The elevator maintenance procedures

Elevator maintenance can be divided into: maintenance, maintenance, maintenance, the first half of the month a year maintenance. As manufacturers have special requirements, in accordance with the manufacturers requirements (see DB11/040-94).

Zhou Baoyang

Basic requirements: 1 elevator required weekly maintenance time, time of not less than two hours, the requirements of maintenance personnel to set people, timing, fixed ladder for maintenance. 2 on the elevator following parts to check, so as to ensure the normal operation, cleaning, lubrication. 2.1. power switch, safety switch. The total gate and limit of 1.1 control cabinet switch electric appliance element is complete without damage, connection solid. 2.1.2. check the fuse, fuse contact, firm connection, there should be no spark phenomenon. 2.1.3. stop, security window, the bottom hole, limit and other safety switch contacts should be a good, normal, reliable action. No cross connection. 2.2. traction machine: the appearance of body should ensure the clean and bright. 2.1 the reducer A. should run smoothly without abnormal vibration. The B. gearbox oil surface height should be kept within the prescribed level line. The C. gearbox oil temperature of not more than 85 DEG C; no friction sound, sound of collision or other noise should be 2.2.2. motor A. motor in operation, if there is abnormal sound should stop staircase check whether there is foreign intrusion of sliding bearing, the bearing is damaged. B. motor oil should be in the vicinity of oil lens center. C. motor use environment temperature should not be higher than 40 DEG C, the temperature rise should not be higher than the nameplate specified. D. motor bearing is not more than 4mm. 2.3. brake. 1 1 steady and reliable action, no skid, brake shoe contact surface is not less than 70%. The 2.3.2. brake is not open, the shoe should hold close, turning round with no hand can dynamic disk. 2.3.3. brake open, both sides gap should be consistent, and four angles on both sides of the average gap value should be less than 0.7mm. 2.3.4. brake opening and closing should flexibly and freely, not more than 60 DEG C temperature rise of coils. 2 control cabinet, electrical elements 2.4.1 cabinet should work normally, instrument accuracy. 2.4.2 no heating phenomenon, each contact point contact tightly without adhesion loss phenomenon; 2.4.3 cabinet anti switch no oil no dust. 2.5. speed system, 2.5.1. speed limiting wheel: clean appearance, flexible action, no obvious month RBI, smooth asphalt, rope nip no foreign body oil, no abnormal wear of wheel groove. 3 2 up rope wheel and a safety clamp device: clean appearance, smooth asphalt, stable rotation, the tensioner mat gas, safety clamp the linkage mechanism is flexible, the jaw and the rail side work surface gap between 2-3mm. 4 layer selection system selector rotation and sliding part of clean and sufficient oil amount, contact cleaner, proper pressure. 5 hall, 2.7.1 hall, elevator door system of car door closed normally, should be able to connect to the door lock network; minimum length of engagement locking element is 7mm, at this time should not be outside the hall door to hand opens. 2.7.2 safety contact plate, photoelectric device with reliable function. 2.7.3. hall door, car door, rotating parts and slide: rotating parts cleaning, can freely rotate, add lubricating oil, slide, debris removal, slide refueling, hanging door wheel, door slider wear timely replacement. 2.7.4. door opening and closing mechanism for opening and closing of the total: clean, activities and rotating parts cleaning refueling, belt tightness appropriate, without slipping, the removal of carbon deposition, cleaning door machine. 6 level explicit system, select, outbound system. 2.8.1. each element indicates normal function, button move freely without jamming. 2.8.2 light display normal, clean and dust-free. 2.9. well system, the 2.9.1. car, counterweight guide shoe and uniform clearance, shoe lining without serious wear. 2.9.2. oil box, oil brush without defect, rail lubrication good. 2.9.3. wire rope tension uniform and no broken strand. 2.10. health, iron gate to the machine room corridor; computer room; car roof; pit and other parts should be kept clean, no garbage, clean out the dirt and dust.

Monthly maintenance

Monthly maintenance is based on the main cleaning maintenance, elevator parts of lubrication, inspection, especially for safety device inspection. 3.1. reducer, 3.1.1. reducer should be no abnormal noise, remove surface dust grease. 3.1.2. worm gear oil for rolling bearing gas, check the coupling has no damage. 3.1.3. check the traction wheel each rope groove wear is consistent, bolt fastening the traction wheel parts. 3.2. motor, generator, removing dust and dirt of the inner and the outer 3.2.1. 3.2.2. velocimetry system works normally, drive system without injury. The lubrication conditions between the 3.3. brake 3.3.1. check the electromagnetic iron core and copper sleeve. 3.3.2. fastening the connecting bolt. Not more than 60 DEG C L 3.3.3. coil temperature. 3.4. speed system, 3.4.1. to clear the rope clamping jaw position of foreign body, oil. Part of the rotary pin shaft gas 3.4.2. 3.4.3. check the governor pulley and a tension pulley wheel groove, there is no abnormal wear. 3.4.4. check the tensioning device and electric switch and action is normal. 3.5. control cabinet, excitation cabinet. 3.5.1. check the various electrical components, instruments, and not sensitive to damage the components should be timely adjusted replacement. 3.5.2. check contactor, relay contact ablation conditions, such as serious uneven shall repair or replace the contact. 3.5.3. check the mechanical interlocking device, to unreliable action should be adjusted. 3.6. wire rope, 3.6.1. Rope Inspection of corrosion and wear, rope bolts should lock, cotter pins are available. 3.6.2. wire rope tension should be uniform. 3.7 hall car door system to remove dust, grease, check each part of the hanging door wheel, door guide rail bearing, daub lubricating oil. 3.8. 3.8.1 clear layer selection system each part of dust and grease, adjust the electrical selector action gap or accuracy. 3.8.2 steel wheel and axle rose rope for refueling, the movable carriage rail lubricating oil. 3.9: to guide rail with automatic lubricating device, should be filling machine lubricating oil. 3.10. safety device, 3.10.1. examination site: open phase protection device, overspeed protection device, mechanical interlocking
