Description

Technical Field

[0001] The utility model relates to the technical field of guide rail commutators, in particular to a commutator for steering with rigid and flexible guide rails. Background Art

[0002] Tower-high work refers to various work activities performed by workers on towers or similar high structures in industries such as communications, broadcasting and power. Such work often involves repairing, installing and maintaining equipment, etc., which has certain risks and challenges and requires workers to have professional skills and safety awareness. When performing tower-high work, wearing a fall arrester is an indispensable measure. By wearing a fall arrester, the rigid and flexible tracks on the tower are interacted to provide fall prevention measures.

[0003] The current anti-fall rigid track and flexible track cannot be seamlessly connected, nor can they be turned. One can only remove the anti-fall device of the rigid guide rail first, and then use the anti-fall device of the flexible guide rail. In terms of safety, it is not a fully enclosed closed-loop operation and there are safety hazards.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0024] like Figures 1 to 5 As shown, the embodiment of the present utility model provides a commutator for rigid and flexible guide rail steering, comprising a fall arrester body 1, a card slot is provided on the fall arrester body 1, a flexible guide rail steel hinge wire 10 is movably installed on the inner side of the card slot, a movable slot is provided through one side of the fall arrester body 1, and the movable slot is communicated with the card slot, two bolts are threadedly installed on one side of the fall arrester body 1, and an anti-slip plate 2 is movably installed on the outer sides of the two bolts, and the anti-slip plate 2 is tightly attached to one side of the fall arrester body 1, two torsion springs 3 are symmetrically connected to the inner walls of both sides of the movable slot, a positioning block 4 is connected between the two torsion springs 3, and the positioning block 4 is in contact with the flexible guide rail steel hinge wire 10, two shaft blocks 5 are symmetrically fixedly installed on both sides of the positioning block 4, and each shaft block 5 is movably passed through one side of the fall arrester body 1 and fixed by a gasket;

[0025] In an embodiment of the present utility model, the fall arrester body 1 is moved to the flexible guide rail steel hinge wire 10 through the card slot, and the anti-drop plate 2 is installed and fixed on the fall arrester body 1 by two bolts, so that the fall arrester body 1 is installed on the flexible guide rail steel hinge wire 10, and the staff ties the rope to the positioning block 4. When the staff drives the fall arrester body 1 to move along the flexible guide rail steel hinge wire 10 through the rope, the torsion spring 3 uses its own elastic force to support the positioning block 4 and the flexible guide rail steel hinge wire 10 to rub. The positioning block 4 moves with the shaft block 5 as the center under friction, and the staff's high-altitude work on the iron tower is installed and protected by the fall arrester body 1 and the rope.

[0026] Figures 1 to 5As shown, a round sleeve 6 is fixedly installed on one side of the fall arrester body 1, and a threaded hole is provided at the top of the round sleeve 6. A telescopic block 7 is movably installed on the inner side of the round sleeve 6. Two round holes are provided inside the telescopic block 7. A positioning bolt 8 is threadedly installed on the inner side of the threaded hole, and the positioning bolt 8 is located on the inner side of a round hole of the telescopic block 7. A ring ring 9 is fixedly installed on one side of the telescopic block 7. Two flexible guide rail supports 11 are movably sleeved on the outer side of the flexible guide rail steel hinge 10, and the two flexible guide rail supports 11 are respectively located at the top and bottom of the ring ring 9. The two flexible guide rail supports 11 are respectively fixedly installed with a steering gear body through two bolts and two nuts, and the steering gear body is located on one side of the fall arrester body 1. The steering gear body is respectively fixedly installed with two rigid guide rail supports 13 through two bolts and two nuts, and a rigid guide rail round steel joint 14 is fixedly installed on each of the rigid guide rail supports 13.

[0027] In the embodiment of the present utility model, the anti-fall device body 1 slides upward along the flexible guide rail steel hinge line 10. When it slides to the diverter body 12, the anti-fall device body 1 is rotated so that the anti-fall device body 1 drives the ring ring 9 to move through the round sleeve 6, the positioning bolt 8 and the telescopic block 7, so that the ring ring 9 at the back is just inserted into the rigid guide rail round steel joint 14. The staff removes the anti-slip plate 2 and twists the positioning bolt 8 so that the positioning bolt 8 can move away from the current circular hole inside the telescopic block 7. The staff moves the anti-fall device body 1 so that the anti-fall device body 1 drives the round sleeve 6 to move under the action of external force, so that the round sleeve 6 is set on the telescopic block 7. The outer side of the block 7 is used to align the threaded hole with the circular hole position of the telescopic block 7 close to the ring ring 9, so that the slot of the fall arrester body 1 is separated from the flexible guide rail steel hinge wire 10. The staff screws the positioning bolt 8 into the inner side of the circular hole currently aligned with the threaded hole position and fixes the circular sleeve 6 so that it can slide left or right along the rigid guide rail. At this time, the fall arrester body 1 has realized the transition from the flexible guide rail to the rigid guide rail, and can be reversed left and right, which can realize closed-loop anti-fall protection during high-altitude operation of the tower, reduce the unprotected state when the rigid guide rail is switched to the flexible guide rail during operation, reduce safety hazards, and prevent accidents.

[0028] Working principle: The staff moves the fall arrester body 1 to the flexible guide rail steel hinge wire 10 through the slot, and fixes the anti-drop plate 2 to the fall arrester body 1 through two bolts, so that the fall arrester body 1 is installed on the flexible guide rail steel hinge wire 10. The staff ties the rope to the positioning block 4. When the staff drives the fall arrester body 1 to move along the flexible guide rail steel hinge wire 10 through the rope, the torsion spring 3 uses its own elastic force to support the positioning block 4 and the flexible guide rail steel hinge wire 10 to rub. The positioning block 4 moves with the shaft block 5 as the center under friction. The staff's high-altitude work on the iron tower is installed and protected by the fall arrester body 1 and the rope. When sliding to the diverter body 12, the fall arrester body 1 is rotated so that the fall arrester body 1 drives the ring ring 9 to move through the round sleeve 6, the positioning bolt 8 and the telescopic block 7. The ring ring 9 at the back is just inserted into the rigid guide rail round steel joint 14. The staff removes the anti-slip plate 2 and screws the positioning bolt 8 so that the positioning bolt 8 can move away from the current inner side of the circular hole of the telescopic block 7. The staff moves the anti-fall device body 1 so that the anti-fall device body 1 drives the circular sleeve 6 to move under the action of external force, so that the circular sleeve 6 is arranged on the outer side of the telescopic block 7, and the threaded hole is aligned with the circular hole position of the telescopic block 7 close to the ring ring 9, so that the slot of the anti-fall device body 1 is separated from the flexible guide rail steel hinge wire 10. The staff screws the positioning bolt 8 into the inner side of the circular hole currently aligned with the threaded hole position and fixes the circular sleeve 6 so that it can slide left or right along the rigid guide rail. At this time, the anti-fall device body 1 has realized the transition from the flexible guide rail to the rigid guide rail, and can be reversed left and right, which can realize closed-loop anti-fall protection during high-altitude operation of the iron tower.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
