<br> With the deepening of China's modernization process, more and more high-rise buildings, as a high-rise building of transportation - elevators, their number also will be increased, especially in the young municipality of Chongqing is ushered in an unprecedented development, .According to statistics, the main city of Chongqing has a lift capacity in the country thirty-one provinces (autonomous regions) ranked tenth, and its growth rate is staggering. .Chongqing City, the only lift as the legal test units - Chongqing City, the quality and safety testing center special equipment bears more than a thousand of the city's thirteen thousand elevator's inspection work, the task facing the elevator is a very difficult test, which we detected in the elevator .The management is both an opportunity and a challenge. .This paper will analyze the conditions of the elevator defects detected on the detection of the impact of the work, and proposed to increase the quality of elevator inspection, protection of test security, improve the detection efficiency of the proposal. .First, the current testing conditions the elevator and the main reason of defects under the supervision and inspection of the elevator the relevant requirements of the testing conditions, supervision and inspection of the elevator should be improved in the case of testing conditions used by the elevator unit testing agencies to test applications. .However, due to various factors, many of the elevator is currently not available in the testing conditions to detect the case, which makes testing work has been greatly affected. .We are currently testing the following conditions exist several defects in the main analysis. .1. .Confused by the elevator test site in Chongqing in 2004 more than 1000 sets a new installation of the elevator inspection found that approximately 80% of the lift does not have the test on-site detection of chaotic conditions, mainly in the following aspects: (1) Lift the power supply does not meet the requirements ., usually temporary construction power to the majority, the power source neither there is a big specification also security risks. .(2) does not flow channel leading to the engine room, stairs without rails, do not have the necessary lighting. .(3) detection of various types of cross-site operating conditions are more prevalent all kinds of noise. .(4) do not have the room, wells and pit lighting, water pit serious. .(5) wells are not completely closed, building materials, internal injuries can easily fall into the wells and testing personnel to test the safety of personnel posed a great threat. .2. .Working poor self-installation and maintenance units under "Regulations on Safety Supervision of Special Equipment" and "Lift Supervision and Inspection Rules," Supervision and Testing of the relevant provisions of the elevator installation and maintenance unit is built on the basis of the self. .However, the actual situation is like? .According to incomplete statistics, the work of the entire inspection unit for self-installation and maintenance caused by inadequate inspection and testing work could not carry out the work difficult to carry out the ratio of approximately 60%. .Mainly in the following aspects. .(1) installation and maintenance units without self links, direct inspection after installation. .(2) installation and maintenance units although there are aspects of self, but self-test report is not complete and sign the above persons without self-self-test unit did not sign, the seized items vague, test data mistaken identity. .(3) Although more standardized self-report writing, but the self-test results and actual test results there is a big difference. .3. .Units on-site installation and maintenance personnel are not in place with the supervision and inspection of the elevator, "the provisions of the lift when carrying out supervision and inspection, elevator installation and maintenance units must be concerned with the testing personnel to the scene detection. .However, contrary to expectations although many elevators have a certain amount of testing on-site co-workers, but the detection efficiency is still not high, resulting in this regard are the following reasons. .(1) with The quality is not high mainly in the testing process are not familiar with. .(2) with the proportion of people with disorders, mainly in electrical, fitter, disproportionate number of porters. .(3) with the staff is not the elevator installation elevator installers do not understand. .To sum up, causing the current condition of the elevator main defects detected although the reasons are many, but their roots are the following. .1. .With the real estate market continues to "heat up" on the increasing demand in the elevator, however, some real estate developers because of lack of capacity for project management and financial operation of the divergence caused by the elevator approach can not be installed at the scheduled time. .2. .As the elevator unit of their own on-site installation of the management is weak, pre-installation installation personnel, installation of equipment investment is not enough, resulting in extended installation period, in order to produce for examination within the time stipulated in the contract the elevator, only late in the installation of grab hard work, making a large installation quality .discount. .3. .Units using the unit and installation of the elevator on the subjective acceptance of the neglect, which is caused by defects in the elevator of the important reasons testing conditions. .Many units currently use the elevator in the elevator contract signed so-called formalities in order to avoid the trouble of signing with the elevator supply unit is the "key project", making use of the elevator unit indifferent about installation issues, and elevator installation .units can not limit the contract to the use of relatively more reasonable demands, the lift does not have the acceptance of this condition, and the use of units to meet the needs of inspection, which is testing the work smoothly lift a layer of cast .shadow. .4. .As noted earlier management of the unit of their own installation and maintenance is more confusion on the elevator inadequate quality control during installation, and installation of officers, staff self-responsibility is not strong, leading to installation of the elevator can not be a problem in the pre-test to receive timely lift .solution, making the elevator work is often detected at a very passive situation. .Second, elevator testing conditions on the detection of the elevator through the elevator on the current testing conditions and related defects analysis of the causes, we believe that the maturity of the elevator test conditions the smooth development of the elevator inspection plays a very important role. Mainly reflected in the following .aspects. .1. .Confusion on the detection of the elevator inspection site running smoothly with great impact. .For example: We have a building on the city's elevator inspection examination revealed that in addition to the elevator machine room surrounded by four walls, the room has neither doors nor lighting, room was filthy and there are some ground water, .power to the elevator from the ground through the work, leading to the room lighting and the channel is not blocked, in which some scaffolding. .When we see these situations, the emotional impact of our testing is undoubtedly exist. .This sentiment is no doubt the quality of testing, testing efficiency, testing the impact of their own security is greater. .On the other hand the detection of the chaotic scene on the detection of physical and mental health personnel, and security testing process problems have a higher requirement. .2. .Working poor self-installation and maintenance units carry out the work on the detection of low efficiency is mainly reflected in the detection, testing pass rate significantly reduced, while safety inspectors also constitute a certain threat. .Since the work of poor self-test allows us to work always in the side of adjustment, edge detection and rectification of a disordered state, while extending the detection time to detect the reduction will increase the efficiency of detection units of the costs, the passing rate of detection of significant .After lowering the lift makes a lot of testing after the first time that virtually had to re-test also increased the cost of installation and maintenance unit. .Large amount of lift as the on-site installation of mechanical and electrical products, if ignored, while the quality of installation and maintenance can not work through the self-test to make timely and effective, no doubt the lives and safety inspectors gave a big threat. .July 2004 at a residential area on the city's elevator inspection of a test found that the direction of the lift installed anti governor, balancing factor seriously overweight, 125% of rated load test emergency stop test is invalid, even more shocking .Acceptance of the elevator before we have put into use. .If you can not unexpected because the safety gear action, the consequences are very serious, the above result, each of us to field test personnel pinched the sweat. .3. .Units on-site installation and maintenance personnel are not in place with the detection of the influence is evident, most notably the work can not be detected in an efficient and orderly atmosphere for the work, it is true, the elevator inspectors testing process no doubt should bear the main .work, but because of the rapid development of a variety of elevator technology elevator control systems and mechanical parts, the installation process there is always some differences, therefore, the work start to finish testing the product needs to know the circuit structure, mechanical structure, the installation .personnel involved in process relies entirely on the technical capacity of inspectors to complete their inspection work is not realistic. .To sum up, the elevator on the detection of test conditions can be divided into positive and negative effects of the two aspects of testing from the current situation a larger proportion of adverse effects, in order to reduce such adverse effects and improve the quality of the elevator inspection .and efficiency measures must be taken. .Third, some suggestions 1. .Units should use the elevator as the elevator elevator inspection work put into use before a major event in the elevator as his property, can not turn a blind eye, as much as possible according to lift and acceptance testing conditions must possess to meet, urge to install units, .create an environment conducive to the acceptance of the elevator inspection. .2. .Installation and maintenance units should strengthen quality management, establish a strong self-awareness, strengthen self-responsibility staff on the elevator with acceptance conditions must be arranged prior to the acceptance of strict self-test, and strive to install the defective, dangerous problems, eliminate .Prior to the acceptance. .And to strengthen communication between units and elevator use. .3. .Installation and maintenance units in response to project quality, testing conditions are ripe, the adequacy of staffing as a measure of several important conditions for the lift test, can not meet the above aspects of the case do not rush to test, because test results can be desired but .known. .4. .Testing testing organizations as the protagonist of the elevator should be considered at an appropriate time for installation and maintenance units to detect a lack of understanding of this process the soft underbelly of their necessary training to enable them to work on the testing associated with the essentials, safety and security .and other sectors have gained a better understanding for the detection of the smooth progress of the work and lay a solid foundation. .Create a good testing environment, attention to the elevator inspection work, can not rely solely on one aspect of the effort to achieve, it will take some time, a certain environment, the joint efforts of all aspects in order to gradually be changed. .And this change is that we want to see. .It can lift units can be expected to use the time to lift into the legitimate operation; elevator installation units through reasonable arrangement, strict self-test to make their products through testing and to obtain a certain profit; elevator inspection agencies to improve the detection .detection efficiency and quality, reduce labor intensity detected. .Testing conditions and testing is not difficult to see the dialectical relationship between the several interests is a win-win, I believe that in the near future with the gradual improvement of conditions of the elevator inspection, elevator inspection will be into the high-quality, high efficiency development track..
