Automobile Elevator Manufacturers introduces the maintenance precautions of the pit part:
- The maintenance personnel wait for the elevator at the entrance of the hall on the bottom floor, and set up obstacles to prevent people from approaching. After the elevator opens, call the elevator to the top floor. After the elevator stops at the top floor, open the hall door and carry out the pit. Partial maintenance.
2. After opening the hall door, take a photo of the emergency stop button of the pit, turn on the lighting of the pit, and observe whether there is water in the pit. If there is water, you need to notify Party A to confirm the notification on the spot, and require the user to perform water treatment or waterproof treatment in the near future. .
3. Check the state of the pit ladder, check whether the tensioning device is operating normally, otherwise it should be adjusted mechanically; check whether the limit switch is in the positive position, if it is not in the normal position, it should be pulled back. The distance between the bottom plane of the tensioning wheel and the ground of the pit should be 500-50MM, and the rope should be cut if it exceeds the regulations.
4. Do the over-travel test of the terminal limit switch, and the over-travel distance is 50-70MM away from the sill of the upper and lower terminal hall doors. The over-travel test of the terminal limit switch is carried out, and the over-travel distance is 150-200MM away from the sill of the upper and lower station halls.
5. Check the gap between the compensation chain and the ground. The distance between the compensation chain and the ground is more than 300MM.
6. Check the buffer distance of the counterweight. The buffer distance of the hydraulic buffer is 250-400, and the buffer distance of the polyurethane or spring buffer is 150-350. If it does not meet the requirements, the lower buffer pressure block of the counterweight should be disassembled. If not, notify A The square unit shall do the processing of stopping the elevator and cutting the steel wire rope.
7. Check the wear of the tensioner wire rope, check the lighting of the pit, and clean up the sundries in the pit.
8. Compensation chain failure: There is a sound of hitting the chain during operation, which is caused by the increase or shortening of the compensation chain. The length of the compensation chain should be adjusted; the safety gear wire rope tensioner is faulty: there is a grinding wire rope sound or abnormal sound during operation. The safety pliers wire rope should be adjusted and the bearing should be replaced; buffer failure: the buffer is rusted, inactive, and the hydraulic oil is insufficient. The rust should be removed and the hydraulic oil should be replenished.
