Weak current College】 【elevator proposal.

<br> <br> Elevator-series products <br> <br> Elevator is the building's vertical transportation, its pros and cons of choosing the configuration is related to the rational utilization of the whole building, in particular on high-rise modern buildings .. Excellent selection configuration means that passengers and goods in building a fast, convenient and safe circulation, means increasing construction area utilization, energy saving devices and while reducing costs. Therefore in the architectural design phase, architects, engineers and owners of elevator should closely matching .reasonable elevator, elevator to truly become the Qu on solidification structure of the music beats in harmony. <br> Elevator configuration should seriously understand building itself and use environment, including the use of a building, size, height, passenger and freight traffic, etc .. For example, in the elevator traffic analysis you need to know the following: (1) building applications, Office building, residential, hotels, Department stores, hospitals, libraries, station, etc., there are multifunctional, multipurpose complex, such as .intelligent buildings. Even office building, a company dedicated to building and private building, zoning rental building, tiered rental building. (2) floors, floor height, the elevator lift height. (3) the number of the building and in the distribution of .each layer. (4) the effective use of the various layers of the area and its purpose (such as a conference room, restaurant, sales shops, offices, etc.). (5) every person who use of floor area. (6 .) building on the ground floor there are around, or transit station, the underground streets, etc. Selection configuration process should consider a number of factors, for convenience, the following will be to influence the factors affecting the efficiency of the lift convey the main .line and take into account other relevant factors. <br> 1 elevator type selection <br> Each type of elevator has its function configuration requirements and use, on its reasonable choice it is necessary to ensure efficient traffic building. Elevator by purpose into passenger elevator ., the freight elevator, passenger and freight elevators, escalators, residential elevator beds, modifications, sightseeing lifts, boat lifts, vehicle lifts, construction elevators, etc., there are also some special-purpose lifts such as: explosion-proof elevator, cold .storage elevators, escalators, lifts for persons with disabilities for household use, mine lift, power plants, such as elevators, fire lift. Such as sightseeing lift can be installed in indoor or outdoor, a circle, lozenges, etc, passengers can watch through .exterior glass car wall. Again such as handicapped elevator, it is ordinary disabled passenger lifts, wheelchair platform elevator and stairs lift chairs, characterized by cabin size, door width, manipulation etc. should fit to take a wheelchair passengers or blind access and manipulation, .generally also set voice-announce and fault sound alarm. Wheelchair use escalator several adjacent cascade can linkage formation support wheelchair platform. <br> Lift the drive way into traction lifts, hydraulic lift, linear motor driven lift, rack and pinion lifts, Web- .driven elevator, screw elevator, oblique lift, etc. Traction lifts is divided into AC elevator and elevator. AC elevator went through Exchange single-speed, AC two-speed, frequency adjusting speed, and other development phase, final variable speed elevator with its .good speed performance and comfort, energy efficiency, driving device is small, the noise low, flat layer of high precision, high reliability and low circuit loading, become the mainstream elevator products. Elevator with speed performance, speed range, etc., but require .DC power supply and motor maintenance difficult, now commonly used for gearless driven 2.00m / s above speed elevator. Hydraulic elevator has well road structure strength requirements low, Wells road utilization high, lifting loads large, stable operation, reliable, flexible room layout and .other features, often used for lifting height lower than 30m, at less than 1.00m / s in the elevator, particularly suited to some old buildings where additional lift. Hydraulic elevator in Europe and the usage is very big, but because of their high energy .consumption, pump noise (using immersion oil-pump can reduce noise), operational state susceptibility to influence, the oil temperature to process tubing, such as security and disclosure issues have recently received a MRL challenges. Linear motor driven elevator use linear motor principle, .generally in the whole coil well road, car, or to reload a permanent magnetic materials, the use of optically controlled technology or radio control, apply to future 1000m high-rise building. Oblique lift cabin in inclined shaft road running along the Rails in, .is a tourist and transport in one of the ramp, travel can exceed 200m. But in order to secure the maximum speed limit is 4.00m / s and the maximum speed limit reduction for 0.5gn. <br> Elevator control according to manipulated is divided .into the handle switch control, button controls, signal control and set control, parallel control, group control and so on, now developed to the single staircase set control and intelligent elevator group control. Press room location into the elevator on the engine room, computer .room, side room and machine-roomless (traction systems and control cabinet placed well road). Elevator by traction machine has no gear consists of a gear-driven (including v-belt driven) and no gear drives, etc. <br> Escalators .and elevators compared to conveying capacity, which can effectively use the architectural space, layers and layers between the continuous conveying passengers that applies to passenger focus of public places such as shopping malls, train stations, airports, theatres, etc. Escalator features according to their .structure is divided into standard, slim type, aggravation. Slim type applies to passenger traffic is not too large and the need to save space, increase the type suitable for large traffic of public transport. The lifting height is divided into small lift height, the .lifting height, great lifting height escalators. The location of the drive unit is divided into end-driven (or chain) and intermediate driver type (or rack), which can be installed more than one set of driving device, applies to the escalator for .large lifting height. According to the driving control into the regular type and frequency control type, which can be through the sensor without people take time to achieve low-speed operation or stopped, passengers coming to automatically revert to the rated speed to save energy and .extend equipment life. By ladder routes-divided into linear type, multiple gradient type, spiral. Multiple grade levels are in the middle of the General, when the great lifting height can reduce fears of passengers on height, and can and building construction stair coordination .configuration. Spiral can save space, with decorative art. <br> Automatic sidewalk can be horizontal transport, allowed less than 12 ° of tilt, applicableIn airports, supermarkets (carrying the shopping trolley). The structure is divided into time-(most common .), belt, two-wire. Recently, Japan has accelerated-belt automatic sidewalk, ie automatic sidewalk to segmentation, passengers from low-speed segment of the entry, and then enter the section of the high speed running smoothly, and then enter the .low-speed segment of the left, so that the passengers up and down automatically when the sidewalk, shortens long stroke of staircase time. <br> Elevators, escalators, automatic sidewalk reasonable match can effectively play their respective strengths. <br> <br .> <br> <br>.
