Regarding installation elevator social practice report

For the thorough knowledge of elevator total structure and the installation whole process, I have been in royal springs bay engaged in a month of elevator's installation work.

From the Angle of speaking, use elevator points passenger lifts, HuoTi, passenger amphibious ladders, sickbed ladder, housing ladder, sundry ladder, special ladder, etc, this practice is installed, the passenger lifts. Elevator by room, elevator car, hall door, well bild a basic components, on the function criterion existence tractive system, guiding system, elevator car system, weight balance system, safety protection devices system and electrical control system, etc.

Pack ladder belong to high-risk assignments, and various, ready to work require fittings is plenty. Generally by 4 to 6 members installation team, including skilled machinery installation fitter and electrician. The installation of mechanical and electrical parts should be adopted parallel operation. Before installation, according to the packing list and relevant technical data and open the package, and for all parts and materials, understand the ladder model, the control mode. According to the arrangement review well tao leave holes, legs, pit depth, top height, layer stand number, layer door type, Wells translumenal endoscopic plane size, if any discrepancy is timely correction. Installation personnel must abide by the installation work site practice should supervise each other, you have to wear a helmet, wearing a seatbelt. In the well, tao measurement to do: understand well at the entrance of the gate of the inner tao plastering type and thickness, Wells tao template airstrip guide centerline and elevator car centerline and size according to the provisions of civil engineering drawings, consider plasterer layer thickness and decide, Should be in advance of the plumbline is marking good fixed position, Measuring record form, to determine the maximum deviation, individual size according to the optimal scheme of the plumbline is revalued fixed position, Cleaning Wells way, erection scaffold, Each machine elevator hoistway tao executes independent power supply, at the bottom of the entrance set switch; Construction power for the power supply should be sent to the telecom room and site of the construction site.

The next mechanical part of installation procedures can be as follows: resettlement model frame, made guide rail, pack of heavy loading buffers, bearing beam, install layer door, spelling elevator car, car door loaded, its frame, open the door machine, guide boots, a safe grips, overload device, pack traction machine, guide wheel, speed device, traction rope, compensation devices. The electric parts installation program for: installation power lines or trough, the layer indicator, summon boxes, fire switch, control cabinets, computer room wiring, well way, computer room of electrical devices. They should be parallel operation, order is for reference only. And clean Wells tao rooms, slow fast commissioning adjustment, the last delivery acceptance.

Above concrete in one part of the detailed installation method is as follows:

Guide installation: 1, according to guide frame the plumbline is, pit channel steel, its levelness does not exceed 2/1000. 2 and removal, guide frame QianChui linear guide rail, according to each column from the center tip-to-face 15mm place, with sample under vertical suspension frame. 3, in room holds a firm pulley below the roof, will guide by the abyss by root upward, first set up shop in 10 millimeter root bottom guide pad or guide seats. 4 "clean guide joints and bolt connection and firm, guide rail linking piece slightly compaction, wait for after correction in firmly.

Install elevator car, will put in elevator car chassis frame fixed chassis meantime mat with the technical specifications of the rubber anti-shock pad, adjust the elevator car frame braces, make the elevator car bottom on the horizontal plane not levelness does not exceed 3/10000. Will assemble good car top, with the hand type hoists hanging in ShangLiang below; Will the car wall and car around the top, sedan chair wall between bolt, and have the car door calibration square rule side thereof wall of lead sag should not exceed 1/10,000, Install armrest, condole top, operation box; etc. Install elevator car door, have door machine elevator car door the collision force should be no more than 150N, if there is safety touch boards, the collision force is not more than 50N; All the installation is completed by hand type hoists brought, in litters bottom USES below balance iron adjust balancing.

The electric parts, well within the tao wire laying wire tube type of installation, determine first installation position of each layer, according to the plumbline is the junction boxes, power lines supporting frame anchor bolt and boldly fixed, according to the number of wires required to determine the wiring diagram specifications of power lines needed tube number, measurement of each layer &type spacing between power lines interception length, the conductor through the wire tube, both ends must show orifice 500mm lengths of wire, convenience and wiring board connection. Wire should be avoid moisture wear tube, sewage immersed.

Somewhere, buffer, safety plier, computer room, traction machine, guide wheel etc parts unknown wrote.

After the elevator installed, its readiness, failure rate and service life depends largely on the routine maintenance. To formulate maintenance plan, take day, week, month, season, year cycle, key in the sun, moon and yearly check to daily inspection, the annual inspection as an example to illustrate. Daily inspection maintenance content includes: 1, in addition to the elevator repairing test, and every day in the engine room should be made within patrol sex is checked. 2, check the brakes, relays, contactor such action is normal operation; Whether at various levels in normal working voltage range. 3, check the room temperature, humidity and motor and reducer, brakes, temperature. 4, listen to the sound and abnormal vibration are betting. 5, smell smell appear without anomalies. 6, inspection operation box of button, switch work; Refers to the layer and direction indicator is normal or not. Yearly check of maintenance scope mainly check-over elevator, and according to the new ladder commissioning procedures test. If stop used longer and earthquake, fire need a detailed examination rear can use.

Maintenance elevator is the most important search for fault. General method of transpedicular elevator in maintenance condition, ensure all layers door closed, in the telecom room point start elevator slow or slow down certain. When can point start elevator running, and coleorhiza sound, smell, can be sure: 1, mechanical system no problem: 2 and the Lord drag circuit: no problem. Fault out in electric control circuit in. Conversely, the fault may be out in the mechanical system or main drag circuit. At first the mains switch, disconnect again, if it can be manually dish car manual plate, the car and no abnormal failure of main drag circuit. If the manual dish car also cannot make elevator car running, or abnormal or different sound, then can judge fault of mechanical system.

Install the elevator is high-risk homework, each installation team should maintain rigorous work style. Through this social practice, the harvest is not only the elevator installation technology, more important is the unity cooperation consciousness, analytical thinking, etc.
