【 Weak current College 】 on elevator emergency rescue---Power By 【 China power house network 】

The elevator was manned by the special equipment, Elevator Safety and reliability is our first concern. However real life due to power outages and failures, fires, accidents and other factors leading to the elevator emergencies occur. How to lift an emergency can make passengers receive timely relief, avoid panic, irrational actions leading to casualties, maximum protection of passengers ' personal security, and device security is doing a good job in the elevator safety work and it is a big issue. With the continuous development of science and technology, the elevator's rescue mode also in pace with the times, now lift rescue more humane, people-oriented on the elevator was fully manifested. Elevator emergency rescue mode has been removed from the traditional "self-help" way to present the most common way "he saved", and to continue to rescue the "automatic" and "remote rescue" and "social specialized rescue" direction. Due to space limitations, this focus on the elevator in a power outage, failure and fire emergency rescue. 1 elevator emergency rescue of basic requirements for the elevator emergency rescue includes effective advocacy, eye-catching alarm mode prompt and effective response and timely rescue and many other aspects. (1) Elevator campaign is to raise awareness of the passenger protect yourself, see important aspects of the basic knowledge and elevator emergency rescue personnel, passengers on the lift there is fear in General, the panic in case of emergency, or do not follow the emergency rescue mode hasty escape that caused the incident. So you want to do a work emergency rescue, the first step to do advocacy work. At present this work done enough place. (2) striking alarm mode prompt. Mainly refers to the elevator car, should have the emergency alarm for instructions to advise passengers of the matters to be noted at this time. (3) effective answer refers to the passengers in distress signal can be effective. (4) timely rescue means receipt of a distress signal, the professionals at maximum speed scene and press the emergency instructions and requirements of the passenger as soon as possible. 2 elevator emergency rescue mode and its development
(1) traditional "self-help": that is, using the car door and safe form of self-help. This is some old elevator in rescue mode. Its basic idea is: when the elevator malfunction was stopped between two floors, passengers may first consider the hand when the last car door (design, the crane rocker must escape death points to ensure that the door can be rubble), so the location available hand pull the hall door wheel will open the door, just consider the escalators from here left; so the location inconvenience will open the door, the Office may then consider open Security window climbing sedan top and then use the same method to open the door to the Office. Elevator on General just car top fittings on a height exceeding siren to be set up with the room 30m intercom system. In addition to the base station or supposes an emergency lock at each end station. Due to the higher failure rate of Elevator, elevator car miles and generally no emergency instructions led off and escape method of accidents caused by wrong from time to time. Now production of elevator has not used this method for rescue.
(2) now common "he saved": this is the embodiment of the emergency, also is the most common ambulance elevator. The basic idea is through the trapped passengers distress signal, by professionals in the ambulance, the car should always have sufficient lighting.
1) passengers in case of emergency, you should take the following calls for help and self protection measures: ① by alarm, intercom systems, mobile phones or elevator car tips way within help, such as the elevator car with patients or other emergency situations, rescue workers should be informed. ② and elevator car doors or opened the car door at arm's length, to listen to management personnel command. ③ When rescuersarrived at the scene before not pry hit the elevator car doors or a security window, may not use any part of the body out of the elevator car. ④ remain calm, to do Flex action to alleviate the emergency stop button on the elevator. GB7588-2003 the elevator manufacturing and installation of the security code for the cabin lighting, emergency warning device requirements of articles: 8.17 car should set permanent electrical lighting, illumination of the control unit should not be less than 50 lx, the cabin floor illumination should not be less than 50lx. 8.17.2 If lighting is incandescent lamp, at least two parallel bulb. 8.17.3 use of Elevator, cabin should have continuous lighting. On power-driven automatic door, when the car stopped at the station, press the door closed automatically 7.8, you can turn off lighting. 8.17.4 should automatically rechargeable emergency lighting power supply under normal lighting power interruption, it can at least be 1W bulb electricity 1h. In normal lighting battery is, it should automatically power up emergency lighting power. 8.17.5 If 8.17.4 power referred to also supply emergency 14.2.3 requirements, its power and alarm device should have a corresponding nominal capacity. 14.2.3 emergency alarm system to enable passengers to 14.2.3.1 the car out for help, installation of passenger car should be easily identifiable and accessible alarm device. 14.2.3.2 the power supply should be from 8.17.4 in emergency lighting power or equivalent power. Note: 14.2.3.2 does not apply to sedan phone and PSTN connections. 14.2.3.3 the device should use an intercom system to continue with the rescue services. In launching this intercom system, the trapped passengers should no longer have to do a different action. 14.2.3.4 If elevator travel greater than 30m, in the car and engine room should be set between 8.17.4 mentioned emergency power supply for 5.10 emergency relief if wells road, staff there were stranded without risk, by car or underground road escape, there should be in the risk Department sets the alarm device. The alarm device shall conform to the requirements of 14.2.3.2 and 14.2.3.3. 15.2.3.1 alarm switch (if any) button is yellow, and marked to identify the bell-shaped symbol: yellow should not and the other button. However, this color can be used to call the registration of "luminescence" signal. 15.12 alarm device accepts the cabin interiorIssue of Corvette, alarm function of Bell or device, it should be clearly marked with the words "the lift alarm." If more than one elevator, should be able to identify is making a call signal cabin.
2) after receiving a distress signal units of measure: elevator use management units shall immediately notify the elevator maintenance units or to lift emergency Center reports. And condolences to those concerned. 16.3 manual should have emergency unlocking key usage, rescue operations.
3) elevator use management unit received a elevator emergencies handler: ① watchkeeping officers found the elevator emergency or receive help signal, shall immediately notify the professional personnel to the scene, at the same time inform the elevator maintenance unit. ② watchkeeping personnel application elevator configuration address intercom system or other feasible way, more informed the elevator car passengers trapped inside. ③ watchkeeping personnel should be aware of the elevator car is parked floor location, trapped, whether patient or other risk factors, such as an emergency should be immediately to the relevant departments and units. ④ elevator use of the management unit of professionals arrives to advance implementation of the rescue program, such as self help, should cooperate with the elevator maintenance units implementing relief. In order to rescue all of the fast, easy, and should be located at door emergency unlocking device.
4) onsite emergency relief implementation first to determine the position of the elevator, and secondly to quickly determine how that site rescue manual emergency operation or electric emergency running control. In General, with the host and disk speed reducer driver wheel with reduction gear can be used manually turning, on the contrary should be used for emergency power operation. If you can use manual turning occasions, an additional emergency power operation is allowed, but in particular for ambulance once only when using a mode of operation. GB7588-2003 the elevator manufacturing and installation of safety norms for on-site emergency provisions are: 12.5 on-site emergency operation 12.5.1 if moves up with rated load capacity of car required operating force not greater than 400N, Elevator drive host should be installed manual emergency operation device to use smooth
