Description

Technical Field

[0001] This utility model relates to the field of elevator guide rail installation technology, and in particular to a positioning and calibration device for elevator guide rail installation. Background Technology

[0002] An elevator is a vertical transportation device used to efficiently and safely transport people or goods between different floors inside or outside a building. Driven by electricity, it uses a guide rail system and traction mechanism to achieve the vertical lifting and lowering of the car. The elevator guide rail is a key component of the elevator system, mainly used to guide the vertical movement of the elevator car and the counterweight, ensuring that the elevator maintains a stable, safe and precise trajectory during operation, similar to the constraint of train tracks on the car to ensure consistent running direction.

[0003] A search revealed that Chinese Patent No. CN216997214U discloses a positioning calibration device for elevator guide rail installation. This device addresses issues such as unstable calibration due to shaking during use and the inability to assist workers in installing guide rail brackets. Therefore, it can accurately install guide rails and assist workers in installing guide rail brackets.

[0004] The aforementioned positioning and calibration device improves the accuracy of guide rail installation. However, when installing guide rails in an elevator shaft, it is usually necessary to align the opposing guide rails. In existing technologies, guide rails are typically positioned manually using string lines and horizontal wooden rods to ensure alignment. However, during the positioning process using string lines and horizontal wooden rods, slight offsets can easily occur due to manual handling, causing the positioning position to deviate. This reduces the accuracy of the guide rail installation, necessitating repositioning and installation, reducing installation efficiency, and making it difficult for the elevator to operate normally.

The slider 8 is slidably connected inside the slide groove 2. A driven bevel gear 9 is fixedly connected to the middle of the bidirectional lead screw 4. A stepper motor 10 is fixedly installed on the upper surface of the fixed housing 3. A driving bevel gear 11 is fixedly connected to the output end of the stepper motor 10. Two handles 30 are fixedly connected to one side of the fixed housing 3. The outside of the bidirectional lead screw 4 is set with threads in opposite directions. The threads of the threaded grooves 6 match the threads of the bidirectional lead screw 4. The plate 7 is easy to stick to the inner wall of the elevator shaft.

[0035] As attached Figure 2As shown, the driving bevel gear 11 and the driven bevel gear 9 are meshed. A fixing rod 12 is fixedly connected to one side of the fixed housing 3. Two stepper motors 13 are fixedly installed in the middle of one side of the fixed housing 3. A screw 14 is fixedly connected to the output end of the stepper motor 13. A moving block 15 is threadedly connected to the outside of the screw 14. A first positioning rod 16 is fixedly connected to one side of the moving block 15. The fixing rod 12 can limit the movement of the moving block 15. When the screw 14 rotates, it can push the moving block 15 to move.

[0036] As attached Figure 1 As shown, a first rubber pad 17 is provided at one end of the first positioning rod 16. The first rubber pad 17 is used to protect and buffer the contact surface between the first positioning rod 16 and the guide rail.

[0037] As attached Figure 6 As shown, a vertical calibration component is provided on one side of the first positioning rod 16. The vertical calibration component includes a connecting sleeve 18, which is fixedly connected to one side of the first positioning rod 16. An adjusting rod 19 is slidably connected inside the connecting sleeve 18. A second positioning rod 20 is fixedly connected to one end of the adjusting rod 19. A second rubber pad 21 is provided at one end of the second positioning rod 20. Multiple positioning holes 22 are opened on one side of the adjusting rod 19. A fixing plate 23 is fixedly connected to one side of the connecting sleeve 18. The adjusting rod 19 facilitates the adjustment of the position and height of the second positioning rod 20, and the second rubber pad 21 facilitates the protection and buffering of the contact surface between the second positioning rod 20 and the guide rail.

[0038] As attached Figure 7 As shown, the inner wall of the fixed plate 23 is provided with multiple limiting grooves 28. A limiting block 24 is slidably connected inside the limiting groove 28. A limiting plate 25 is fixedly connected to the lower surface of the limiting block 24. A positioning post 26 is fixedly connected to the middle of the limiting plate 25. A spring 27 is fixedly connected to one side of the limiting plate 25. Multiple springs 27 are fixedly connected to one side of the inner wall of the fixed plate 23.

The limiting block 24 slides inside the limiting groove 28 to limit the movement of the limiting plate 25. The limiting plate 25 is used to prevent the positioning post 26 from sliding out of one side of the fixed plate 23. The spring 27 provides elastic pushing force to the positioning post 26.

[0039] Working principle: When in use, first hold the two handles 30 to lift the mounting plate 1 and place it horizontally in the elevator shaft at a suitable position. Then turn on the stepper motor 10, and use its output end to drive the active bevel gear 11 to rotate. Under the meshing of the active bevel gear 11 and the driven bevel gear 9, the driven bevel gear 9 is driven to rotate, thereby driving the bidirectional lead screw 4 to rotate. When the bidirectional lead screw 4 rotates, under the action of the slider 8 sliding inside the slide groove 2, it drives the two moving rods 5 to move in opposite directions outside the bidirectional lead screw 4, driving the corresponding plates 7 to move closer to the inner wall of the shaft. When the plates 7 on both sides are tightly attached to the inner wall of the shaft, the mounting plate 1 is horizontal and suspended and fixed.

[0040] Then, according to the installation environment, when adjusting the distance between the first positioning rod 16 and the second positioning rod 20, pull the pull frame 29, so that the pull frame 29 drives multiple positioning posts 26 to slide on one side of the fixing plate 23 and the connecting sleeve 18. At this time, the limiting plate 25 follows the movement of the positioning posts 26, causing the limiting block 24 to slide inside the limiting groove 28. One end of the positioning post 26 is disengaged from the corresponding positioning hole 22. Then, the adjusting rod 19 is moved up, so that the adjusting rod 19 slides inside the connecting sleeve 18, which facilitates the second positioning rod 20 to move up and increase the distance from the first positioning rod 16. When the second positioning rod 20 moves up to the appropriate position, the pull frame 29 is released. Under the action of the rebound of multiple springs 27, multiple positioning posts 26 are driven to be inserted into the corresponding positioning holes 22. With the connection of the adjusting rod 19, the second positioning rod 20 is fixed.

[0041] After placing the elevator guide rail in the appropriate position, hold the elevator guide rail with one hand, and then turn on the stepper motor 13 on the corresponding side. Under the action of the screw 14 rotating at its output end and under the action of the fixed rod 12 limiting, the moving block 15 moves in the direction of the screw 14, causing the first positioning rod 16 and the second positioning rod 20 to move and hold the elevator guide rail in place. Then release your hand, so that the elevator guide rail can be assisted in positioning in the appropriate position before proceeding with the next routine installation operation.

[0042] 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.
