And then temporarily blocking the hall hole, and placing a fence and a slogan warning. And then removing the top guardrail of the lift car and the pit counterweight guardrail, then removing all connecting lines between the door machine and the lift car top electric box, then removing all connecting lines between the door machine and the top electric box, then removing the lift car door, and finally removing the fixed frames of the door machine and the door machine.
Disassembling the car roof and the side walls;
the door lock loop is closed, the elevator is opened to a maintenance state at the elevator car roof, and then the elevator is opened to a proper position, so that after the elevator car roof is detached, the weight of the elevator car can be reduced, the weight difference with the counterweight of the elevator can be increased, and in general, the elevator can be opened to the top layer. And (3) turning off the three-phase power of the machine room for supplying power to the elevator, detaching the illumination and the fan in the car, and then detaching the car top correction device. When the top of the car is of an integral structure and the decorative roof is arranged in the car, the decorative roof in the car is removed firstly, then the four angles of the car roof are firmly bound by binding ropes on the girder, then the connecting screws are detached, and the car roof is pulled up by pulling the ropes so as to be separated from the four walls of the car. The three-phase electricity is started, a worker on the car roof stands on the girder, the emergency stop switch is normal, the worker drives the car slowly to enable the car to reach a building, then one to two workers are led to go down into the pit, the connection screw of the car wall and the car bottom plate is removed, after the elevator is completely removed, the elevator is slowly lifted, the worker climbs out from the pit, the car wall is separated, the separated car wall is taken out from the well, and then the suspended car roof is slowly put down and moved out of the well by using a rope. And then the elevator slow-running car is moved to the position of the middle floor, a proper number of counterweight blocks are taken down from the counterweight, 4-6 counterweight blocks are generally left, so that the counterweight is slightly heavier than one side of the car, and a worker can work by means of gravity when a machine room is coiled, thereby saving the physical strength.
Removing small parts of the car and cables;
the slow car is driven to the top layer, the three-phase power supply is removed from the machine room, the junction box and the plug-in unit on the car top are removed, the linking end of the machine room and the travelling cable is removed, and the travelling cable is thoroughly pulled out of the well from the machine room or put into the well and pulled out of the well from the pit.
Removing the elevator guide rail and the bracket, wherein the main guide rail and the auxiliary guide rail are removed simultaneously by using an auxiliary unloading device;
a rope is put into a well from a machine room through pulleys, then a part of counterweight is taken down, so that one side of a lift car is unbalanced, at the moment, the lift car is on the top layer, a coiling machine is on a proper position, bolts between a main guide rail bracket and a pressing plate and connecting plates of guide rails and guide rails on the top layer are removed, an auxiliary unloading device is arranged on the lift car, the main guide rail and the auxiliary guide rail are cut and collected in a segmented mode through an auxiliary unloading tool, and then the well is removed from a hoistway door hole of each layer. And finally, pulling the rope manually to drag the bottom guide rail out of the hall door hole of the upper layer.
Removing the bottom plate of the lift car;
the four pull rods of the bottom plate of the car are detached, then the electric hoist is hung on the portal frame, and one end of the bottom plate is lifted by the electric hoist and hung. And then the bottom plate is pulled out of the well, during the period, the hoist can be properly released and pulled to adjust the angle and the position of the bottom plate, so that the bottom plate can be pulled out of the well conveniently, and finally, the electric hoist can be detached.
Dismantling a traction system;
firstly, the tensioning wheel of the pit is removed, then the connection part of the speed limiter wire rope and the pull rod of the upper safety tongs is loosened, and a worker pulls the speed limiter wire rope into a machine room. Because the elevator car bottom plate has been detached in the previous step, the counterweight side of the whole elevator obviously will be heavier than the car side, at this time, the machine room jigger is started, the counterweight frame is put into the pit, the rest counterweight is moved down, and the guide shoes below the counterweight frame are detached. After the balance weight is detached, the weight of the portal frame is larger than that of the balance weight frame, at the moment, a machine room jigger is started again, the portal frame is placed in a pit, then the lower guide shoe and the safety tongs of the portal frame are detached, two of the five steel wire ropes at the connecting end of the portal frame are detached, then the detached two steel wire ropes are pulled into the machine room in the machine room and are bound on a main frame girder, the balance steel wire ropes on the portal frame are detached, then the two bound steel wire ropes are loosened in the machine room, and then the steel wire ropes are tensioned and slowly released until the balance weight frame is placed in the pit.
Cleaning a well and a speed limiter;
firstly, connection of the steel wire ropes and the end of the counterweight frame is removed, then five steel wire ropes in a well are recovered and moved out of the well, the counterweight frame is moved out of the well, guide shoes above the counterweight frame are removed, parts in the portal frame are removed, the parts are moved out of the well, and then the buffer is removed.
Referring to fig. 1 and 2, in other possible embodiments of the present application, in order to enable objects detached from a hoistway to be removed from a hoistway door hole more conveniently and rapidly, a box body with an opening at one side is used for sealing the hoistway door hole, and the box body can be made of a wood board, and a double door is arranged on one side, opposite to the opening side, of the box body, so that the box body is convenient to open and close manually.
Further, in order to make the weight difference between the counterweight side and the car side be too large in the recovery and disassembly processes of the waste elevators, the waste elevators are too fast in the starting process, so that safety accidents are caused, and therefore the number of counterweight blocks should be adjusted timely according to the weight of the disassembled parts, so that the speed of the waste elevators is relatively uniform in the starting process, and the safety performance is improved.
Referring to fig. 3 and 4, the embodiment of the application also discloses an auxiliary unloading device, which is mainly used for the waste elevator recycling unloading method disclosed in the embodiment above, and comprises a bracket 1, a cutting mechanism 2, a storage frame 3 and a weight meter 4.
