[0002] The elevator shaft, abbreviated as the hoistway, is a vertical passage in a building specially used for elevators to travel up and down. Its cross-section is rectangular or square. Generally, one shaft is used by one elevator. Under special circumstances, two or more elevators can share one shaft in parallel. Doorways are opened on the floor of each floor, and hoistway doors can be installed. The hoistway is equipped with guide rails for the elevator car and the counterweight to slide. The bottom pit of the hoistway is equipped with buffers for the elevator car. The motor and transmission machinery are mostly installed at the top of the hoistway.

[0003] An existing patent (publication number: CN 218261451 U) discloses an elevator shaft side wall car anti-collision protection device, which is equipped with a vibration sensor to monitor the vibration of the car surface, thereby avoiding the problem that the car vibrates due to collision and the corresponding protective measures cannot be taken. By arranging a hydraulic rod, a connecting plate, a thrust plate, a buffer spring, a conical column and a cylinder, the collision of the car can be better buffered, thereby achieving the purpose of reducing the vibration caused by the collision of the car, and playing a role in conveniently and quickly eliminating the shaking caused by the collision of the car, thereby avoiding the collision of the elevator car with the side wall of the shaft, causing the car to vibrate, affecting the riding comfort of the passengers, and increasing the safety hazards of the passengers.

[0004] However, the above technical solution still has certain defects. The elevator shaft side wall car anti-collision protection device fixes the shaft body and the connecting shell through a stabilizing plate. However, if the internal device of the connecting shell is damaged after fixation, it is not convenient to disassemble the connecting shell, so it takes a lot of time to repair. For this reason, an elevator shaft side wall car anti-collision protection device is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0028] The quick release mechanism 200 includes an insert block 290 arranged inside the slot 110, a servo motor 240 is arranged inside the insert block 290, a rotating rod 230 is connected to the output end of the servo motor 240, a wire rope 220 is fixed to the outer wall of the rotating rod 230, one end of the wire rope 220 away from the rotating rod 230 is fixedly connected to a limiting block 210, the limiting block 210 is arranged inside the limiting groove 120 and is clamped therewith, one end of the wire rope 220 of the limiting block 210 is fixed with a return spring 250, one end of the return spring 250 away from the limit block 210 is fixed with a frame 260, the frame 260 is fixed inside the insert block 290, one end of the insert block 290 away from the slot 110 is fixed to the outer wall of the connecting shell 270, and the outer wall of the connecting shell 270 is provided with an insert block 290.

[0029] When the anti-collision mechanism 300 inside the connecting shell 270 fails, the servo motor 240 is started to drive the rotating rod 230 to rotate. When the rotating rod 230 rotates, it drives the rope 220 to move, so that the limit block 210 is removed from the limit groove 120. At this time, the staff can separate the connecting shell 270 from the well body 100, and then maintain the inside of the anti-collision mechanism 300. Conversely, during installation, the slider 280 and the insert block 290 are used for positioning and insertion. Then the servo motor 240 reverses the tension of the contact rope 220, and drives the limit block to be inserted into the limit groove 120 and locked with it through the reset spring 250, so that the connecting shell 270 and the well body 100 can be quickly disassembled and assembled, avoiding the need to spend a lot of time on disassembly, resulting in extended subsequent maintenance time.

[0030] Please refer to Figures 2 to 4 Through grooves are provided on both sides of the well body 100, and sliding grooves are provided on the inner walls of the through grooves, and the sliding grooves match the sliders 280, the slots 110 and the limit slots 120 are symmetrically arranged according to the transverse central axis of the well body 100, and an anti-collision mechanism 300 is fixed on the inner wall of the connecting shell 270.

[0031] The through grooves on both sides of the well body 100 are provided for the push plate 330 to move, and the sliding grooves are provided for the slider 280 to be inserted.

[0032] Please refer to Figure 1 and Figure 4 The anti-collision mechanism 300 includes a telescopic column 310 fixed on the inner wall of the connecting shell 270, a push plate 330 is fixed on the end of the telescopic column 310 away from the inner wall of the connecting shell 270, a buffer spring 320 is provided on the outer wall of the telescopic column 310, and the buffer spring 320 is fixed between the inner wall of the connecting shell 270 and the push plate 330, and a plurality of groups of rollers 340 are provided on the end of the push plate 330 away from the telescopic column 310, and the plurality of groups of rollers 340 are distributed in a linear array, and a track 350 is provided on the other side of the roller 340 and is slidably connected thereto, and the track 350 is opened on the outer wall of the car 400.

[0033] The push plate 330 is buffered and displaced by the telescopic column 310 and the buffer spring 320 in the anti-collision mechanism 300. When the car 400 collides, the roller 340 contacts the track 350, so that the buffer spring 320 is used to reduce the shock of the push plate 330 to avoid vibration of the car, thereby protecting the safety of the passengers. The structure is simple and easy to maintain.

[0034] During use, when the anti-collision mechanism 300 inside the connecting shell 270 fails, the servo motor 240 is started to drive the rotating rod 230 to rotate.

At this time, the staff can separate the connecting shell 270 from the well body 100, and then maintain the inside of the anti-collision mechanism 300. Conversely, during installation, the slider 280 and the insert block 290 are used for positioning and insertion, and then the servo motor 240 reverses the tension of the contact wire rope 220, and drives the limit block to be inserted into the limit groove 120 and contact it with it through the reset spring 250. The locking mechanism 300 can quickly disassemble and assemble the connecting shell 270 and the shaft body 100, thereby avoiding the need to spend a lot of time on disassembly, which would extend the subsequent maintenance time. The push plate 330 is buffered and displaced by the telescopic column 310 and the buffer spring 320 in the anti-collision mechanism 300. When the car 400 collides, the roller 340 contacts the track 350, so that the buffer spring 320 is used to reduce the shock of the push plate 330 to avoid vibration of the car, thereby protecting the safety of the passengers. The structure is simple and easy to maintain. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
