[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-3 One embodiment of this utility model is an elevator verticality detection device, comprising:

[0030] The housing 1 has an LED light 16 mounted on its top front end. A frame 15 is fitted around the outer wall of the LED light 16, and both sides of the frame 15 are slidably connected to the top side of the housing 1. A colored light-transmitting plate is provided on the rear side of the frame 15. A trigger head on the front side of the frame 15 triggers its sliding motion. When the trigger head, used for detecting the verticality of the elevator rail, triggers the frame 15 to slide, the color of the light emitted by the LED light 16 through the colored light-transmitting plate changes. The trigger head includes a rotating mechanism fixedly connected to the front side of the housing 1. The base 11 and the detection rod 12 located on the front side of the housing 1 are provided. The front end of the detection rod 12 is rotatably connected to a rotating wheel that abuts against the elevator slide rail. The inner wall of the rear end of the detection rod 12 is rotatably connected to the outer wall of the base 11. Torsion springs are provided on both the left and right sides of the rear end of the detection rod 12. The outer wall of the rear end of the detection rod 12 is connected to the frame 15 through a meshing assembly. The meshing assembly includes teeth 13 fixedly connected to the outer wall of the detection rod 12. A rack 14 is fixedly connected to the front side of the frame 15. The teeth 13 and the rack 14 mesh with each other.

[0031] Specifically, the LED light 16 emits penetrating, strong light. After passing through the colored light-transmitting plate, the strong light is reflected in color to the human eye. As the colored light-transmitting plate moves with the frame 15, the color of the strong light changes, and the human eye immediately detects this color change. When the device ascends on the elevator rail, the torsion spring connected to the detection rod 12 is compressed. The force generated by the resetting is applied to the detection rod 12, causing the wheel on the detection rod 12 to continuously contact the surface of the elevator rail. When the wheel moves to a twisted, protruding, or concave area of ​​the elevator rail, the wheel in contact with the elevator rail moves along the twisted surface, causing the detection rod 12 connected to it to change angle. This causes the detection rod 12 to rotate on the rotating seat 11, and the teeth 13 on its rear side engage with the rack 14, causing the frame 15 connected to the rack 14 to move. This causes the colored light-transmitting plate to move with the frame 15, changing the color of the light emitted by the LED light 16 and alerting elevator inspectors that there is an abnormality in the elevator rail at this location.

[0032] The rear wheel frame 2 is slidably connected to the left and right sides of the rear end of the housing 1. The bottom side of the rear wheel frame 2 is rotatably connected to the climbing wheel 3. The climbing wheel 3 is connected to the motor 6 through the transmission assembly. The motor 6 is used as the driving source to drive the climbing wheel 3 to rotate so that the device can climb on the elevator sliding track. The transmission assembly includes a first synchronous wheel 7 and two second synchronous wheels 8. One side of the first synchronous wheel 7 is fixedly connected to the driving end of the motor 6, and the other side of the first synchronous wheel 7 is rotatably connected to the connecting seat 5. One side of the second synchronous wheel 8 is rotatably connected to the inner wall of the rear wheel frame 2, and the other side of the second synchronous wheel 8 is connected to the top side of the climbing wheel 3 through two meshing bevel gears. The first synchronous wheel 7 and the two second synchronous wheels 8 are connected through the inner side of the synchronous belt. The front wheel frame 17 is fixedly connected to the front side of the rear wheel frame 2. The bottom side of the front wheel frame 17 is rotatably connected to the auxiliary wheel 18. The adjacent sides of the two front wheel frames 17 are slidably connected to the housing 1.

[0033] Specifically, when the device is displaced, the motor 6 drives the synchronous pulley 7 to rotate, which in turn drives the synchronous pulley 8 to rotate via the synchronous belt. Under the action of two meshing bevel gears, the two climbing wheels 3 are driven by the synchronous pulley 8, causing them to rotate in opposite directions. This causes the climbing wheels 3, which are in contact with the elevator rail, to move on the elevator rail through friction.

[0034] The slide 4 has a connecting seat 5 slidably connected inside it. The motor 6 is fixedly connected to the bottom side of the connecting seat 5. An adjustment component is provided on the front and rear sides of the connecting seat 5 to adjust the distance between the two rear wheel frames 2 to accommodate elevator slide rails of different widths. The adjustment component includes a bidirectional screw 10 rotatably connected to the bottom of the housing 1. The bidirectional screw 10 is located on the front side of the slide 4. The front side of the rear wheel frame 2 is threadedly connected to the outer wall of the bidirectional screw 10. The top side of the middle end of the bidirectional screw 10 is connected to a screw 9 through two meshing bevel gears. The front end of the connecting seat 5 is threadedly connected to the outer wall of the screw 9. The threaded connection part is an additional protrusion. The top side of the screw 9 penetrates the top side of the outer wall of the housing 1 and is connected to the top side of the housing 1 through a damping shaft, so that the screw 9 cannot rotate when it is not subjected to sufficient external force, which plays a stabilizing role and prevents the two climbing wheels 3 from loosening during the climbing and lifting operation. A force application handle is fixedly connected to the top side of the screw 9.

[0035] Specifically, when adjusting the distance between the climbing wheel 3 and the auxiliary wheel 18, the screw 9 is rotated by turning the force handle connected to the screw 9. This rotation causes the double-acting screw 10 to rotate through two meshing bevel gears, thereby displacing the rear wheel frame 2. This adjusts the distance between the climbing wheel 3 connected to the rear wheel frame 2 and simultaneously causes the front wheel frame 17 and the auxiliary wheel 18 to slide on the housing 1. The screw 9 drives the connecting seat 5 to move, thereby displacing the first synchronous wheel 7. After the second synchronous wheel 8 moves with the rear wheel frame 2, the synchronous belt remains taut. The maximum displacement limit is limited to the normal wrap angle of the synchronous belt, ensuring normal transmission between the first synchronous wheel 7 and the second synchronous wheel 8.

[0036] Working Principle: Before testing the elevator slide rail, the device is adjusted according to the specifications of the elevator slide rail. The climbing wheel 3 and auxiliary wheel 18 are placed on the elevator slide rail. By turning the force handle connected to the screw 9, the screw 9 rotates, which in turn drives the bidirectional screw 10 to rotate through two meshing bevel gears. This causes the rear wheel frame 2 to move, adjusting the distance between the climbing wheel 3 connected to the rear wheel frame 2. Simultaneously, the front wheel frame 17 and auxiliary wheel 18 slide on the housing 1. The screw 9 drives the connecting seat 5 to move, which in turn drives the synchronous wheel 7 to move. After the synchronous wheel 8 moves with the rear wheel frame 2, the synchronous belt remains taut. Then, the motor 6 is started, driving the synchronous wheel 7 to rotate. The synchronous wheel 7 drives the synchronous wheel 8 to rotate through the synchronous belt. Under the action of the two meshing bevel gears, the two climbing wheels 3 move... The lifting wheel 3 is driven by the synchronous wheel 8, which causes the two climbing wheels 3 to rotate in opposite directions. The climbing wheels 3, which are in contact with the elevator slide rail, move on the elevator slide rail through friction. When the device climbs on the elevator slide rail, the torsion spring connected to the detection rod 12 is compressed. The force generated by the reset is applied to the detection rod 12, causing the rotating wheel on the detection rod 12 to continuously contact the surface of the elevator slide rail. When the rotating wheel moves to the area of ​​the elevator slide rail that is twisted, protruding or concave, the rotating wheel in contact with the elevator slide rail moves along the twisted surface and drives the detection rod 12 connected to it to change its angle. The detection rod 12 rotates on the rotating seat 11 and causes the teeth 13 on its rear side to mesh with the rack 14, causing the frame 15 connected to the rack 14 to move. This causes the colored light-transmitting plate to move with the frame 15, causing the color of the light emitted by the LED light 16 to change, reminding the elevator inspector that there is an abnormality in the elevator slide rail.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
