Description

Technical Field

[0001] This utility model relates to the technical field of fall protection devices, specifically a self-positioning steering device for fall protection. Background Technology

[0002] In power transmission lines, towers consist of crossarms and tower bodies. When workers climb, fall protection devices are required throughout the process. At the junction of the tower body and crossarm, a switching device is needed to allow the self-locking device to smoothly transition from the tower body to the crossarm without derailment. However, in practice, when workers climb from the vertical sliding rail to the horizontal direction of the crossarm, it is generally necessary to first detach the self-locking device and other components from the vertical sliding rail, change direction, and then place them back into the horizontal sliding rail of the crossarm to ensure the self-locking device functions properly. However, this method increases the risk of workers losing their grip and falling during the reversal process, leading to accidents.

[0003] Existing fall arrestor self-positioning steering devices have poor stability in limiting position after steering adjustment, and the existing fall arrestor self-positioning steering devices have poor stability in the connection between the steering device and the external guide rail, resulting in poor practicality. The present invention provides a fall arrestor self-positioning steering device that solves the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1 to 4 This utility model provides a technical solution: a self-positioning steering device for fall prevention, comprising a steering cavity base 1, an external guide rail 2, a steering guide rail 3, and bolts 4. The steering cavity base 1 has an annular groove with the vertical direction as the depth direction. The end of an annular slider 7 is located inside the annular groove. The steering cavity base 1, the disc 6, and the annular slider 7 all share the same center. The top of the steering cavity base 1 has an arc-shaped groove, and the end of the positioning slider 5 is located inside the arc-shaped groove. The maximum distance between the center of the steering cavity base 1 and the edge of the steering guide rail 3 is less than the minimum distance between the center of the steering cavity base 1 and the arc-shaped baffle 24. The end of the external guide rail 2 is inserted into the connecting base 16. The bottom of the steering guide rail 3 is respectively equipped with a positioning slider 5 and a disc 6. The outer surface of the disc 6 is equipped with an annular slider 7, and the bottom of the disc 6 is equipped with a mating plate. 8. Inside the mating plate 8, a pulley 9 is rotatably connected via a shaft. The pulley 9 abuts against the inner bottom wall of the steering gear cavity base 1. A bolt 4 passes through the through hole and is threadedly connected to a nut 17. A limit groove is formed on the outer surface of the disc 6. A magnetic block 10 is installed inside the limit groove. A rectangular slide groove is formed inside the steering gear cavity base 1. A limit spring 11 is installed inside the rectangular slide groove. A rectangular slider 12 is installed at one end of the limit spring 11. The end of the rectangular slider 12 is located inside the rectangular slide groove. The rectangular slider 12 can slide along the length of the rectangular slide groove. A limit rod 13 is installed at one end of the rectangular slider 12. The end of the limit rod 13 near the magnetic block 10 is inserted into the limit groove. An iron block 14 is magnetically connected to the magnetic block 10. There are two limit grooves. An iron block 14 is installed at one end of the limit rod 13, and a pull plate 15 is installed at the other end of the limit rod 13.

[0028] In use, when the steering guide rail 3 turns, the operator pulls the pull plate 15, causing the limit rod 13 to move the rectangular slider 12 and the iron block 14. This causes the rectangular slider 12 to slide along the length of the rectangular groove, causing the limit spring 11 to contract and separate the iron block 14 from the magnetic block 10. This moves the limit rod 13 and the iron block 14 away from the limit groove. Then, the steering guide rail 3 is rotated, causing the disc 6 to move the annular slider 7, the positioning slider 5, and the pulley 9. The annular slider 7 moves auxiliaryly inside the annular groove, and the positioning slider 5 moves along the length of the arc-shaped groove, serving a positioning and steering function. The pulley 9 assists in the movement. The function of the arc-shaped baffle 24 is to facilitate the steering adjustment of the steering guide rail 3. When the steering guide rail 3 rotates, it acts as a limit to prevent the connector on the worker's body from derailing and to prevent falls. When the positioning slider 5 moves from one end of the arc-shaped slide groove to the other end, the limit rod 13 is aligned with another limit groove on the disc 6. At this time, the pull plate 15 is released, and the elastic tension of the limit spring 11 causes the end of the limit rod 13 to be inserted into the interior of the limit groove, so that the iron block 14 and the magnetic block 10 are magnetically connected, which facilitates the position of the disc 6 and improves the stability of the position of the steering guide rail 3 after steering adjustment.

[0029] Example 2

[0030] Please see Figures 1 to 6 This utility model provides a technical solution: a self-positioning steering device for fall prevention. A connecting base 16 is installed on the outer surface of the steering device cavity base 1. Both the connecting base 16 and the external guide rail 2 have through holes. A nut 17 is installed on the back of the connecting base 16. A cavity frame 18 is installed on the side of the connecting base 16 away from the nut 17. A guide hole is opened inside the cavity frame 18. A guide rod 21 is inserted into the guide hole. A limiting baffle 22 abuts against the end of the bolt 4. A return spring 19 is installed inside the cavity frame 18. An adjusting block 20 is installed at one end of the return spring 19. A guide rod 21 is installed on one side of the adjusting block 20. A limiting baffle 22 is installed on the top of the adjusting block 20. A push block 23 is installed at the bottom of the adjusting block 20. An arc-shaped baffle 24 is installed on the top of the steering device cavity base 1.

[0031] In use, when connecting with the external guide rail 2, insert the external guide rail 2 into the interior of the connecting base 16, aligning the through hole on the external guide rail 2 with the through hole on the connecting base 16. Then push the push block 23, causing the push block 23 to move the adjusting block 20, guide rod 21, and limit baffle 22, causing the return spring 19 to contract under force, moving the limit baffle 22 away from the position corresponding to the through hole, and causing the guide rod 21 to slide along the length direction of the guide hole. Then, the bolt 4 passes through the through hole, and the bolt 4 is threadedly connected to the nut 17 fixed on the connecting base 16. Tighten the bolt 4, and then release the push block 23. Through the elastic tension of the return spring 19, the adjusting block 20 drives the limit baffle 22 to reset, causing the limit baffle 22 to abut against the end of the bolt 4, restricting the position of the bolt 4, preventing the bolt 4 from loosening and falling off, and improving the stability of the connection with the external guide rail 2.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
