Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: an anti-falling protection device for power inspection and maintenance, comprising a base 1, two fixed plates 2 are fixedly connected to the top of the base 1, a pay-off wheel 3 is rotatably connected between the two fixed plates 2, a bracket 4 is arranged outside the two fixed plates 2, a limit position assembly is arranged between the fixed plate 2 and the bracket 4, a hook 5 is fixedly connected to the top of the bracket 4, a limit position shell 6 is arranged on the top of the base 1, a rolling shaft 7 is rotatably connected to the middle of the limit position shell 6, and the limit position assembly can be adjusted by the limit position shell 6 and the rolling shaft 7. , thereby preventing friction between the rope and the base 1 when the rope is pulled, a pressure block 8 is fixedly connected to the bottom of the limit shell 6, and the pressure block 8 is slidably connected to the middle of the base 1, and a pull rope 9 is fixedly connected to the outside of the pressure block 8, and the other end of the pull rope 9 is fixedly connected to the limit plate 10, and a compression spring 13 is fixedly connected to the side of the limit plate 10 close to the pressure block 8, and the other end of the compression spring 13 is fixedly connected to the inside of the base 1, and a connecting plate 11 is fixedly connected to the outside of the limit plate 10, and the connecting plate 11 is slidably connected to the middle of the base 1.
[0033] Reference Figure 1-Figure 3A slide groove 21 is provided in the middle of the base 1, and the connecting plate 11 is slidably connected to the middle of the slide groove 21. The connecting plate 11 can be limited by the slide groove 21, thereby preventing the connecting plate 11 from tilting when moving. At the same time, the limiting plate 10 can only move in parallel, avoiding the problem of deformation and damage caused by the inclined extrusion of the pull rope 9, which can improve the service life of the pull rope 9. The two connecting plates 11 are fixedly connected to the side close to each other with a clamping plate 12. When the staff falls, the rope can squeeze the pressure block 8. At this time, the pull rope 9 can be pulled and the pull rope 9 can drive the limiting plate 10 to compress the compression spring 13. At the same time, when the limiting plate 10 moves, the connecting plate 11 and the clamping plate The cam 12 is used to hold the rope in place and to prevent the worker from falling. The cam 12 is used to hold the rope in place and to prevent the worker from falling. The cam 12 is used to hold the rope in place and to prevent the worker from falling.
[0034] Reference Figure 4 and Figure 5 The limiting assembly includes a support plate 14, which is arranged on the outer side of the fixed plate 2. The adjacent sides of the two support plates 14 are fixedly connected with T-blocks 19, and the T-block 19 is slidably connected to the middle part of the fixed plate 2. A T-slot 20 is opened in the middle part of the fixed plate 2. The T-block 19 is slidably connected to the middle part of the T-slot 20. The T-block 19 can be limited by the T-slot 20, so that the T-block 19 can only move vertically, so that the T-block 19 can slide smoothly in the fixed plate 2. The bracket 4 is fixedly connected to the top of the support plate 14, and the bottom of the support plate 14 is fixedly connected with a pull rope 15, and the other end of the pull rope 15 is fixedly connected with an arc plate 16, and the arc plate 16 is fixedly connected with a compression spring 17 on the side close to the pull rope 15, and the other end of the compression spring 17 is fixedly connected to the inside of the base 1.
[0035] Reference Figure 4 and Figure 5When the bracket 4 moves upward, one end of the pull rope 15 can be pulled under the action of the T-block 19. At this time, when one end of the pull rope 15 moves, the other end pulls the arc plate 16. The arc plate 16 can compress the compression spring 17 when moving. At this time, the base 1 can be placed on a separate shelf in the wire rack. At this time, the tension on the bracket 4 disappears, and the arc plate 16 can be reset by the compression spring 17, so that the base 1 can be fixed. The base 1 can be quickly removed by pulling the bracket 4. The base 1 is slidably connected inside the base 1 with a partition, which is fixedly connected between the arc plate 16 and the compression spring 17. The arc plate 16 can be limited by the partition, so as to prevent the arc plate 16 from tilting when moving, avoiding the problem of deformation and damage of the compression spring 17 due to tilting and squeezing, and the service life of the compression spring 17 can be improved.
[0036] Reference Figure 4 and Figure 5 The base 1 is internally rotatably connected with a roller 18, and the roller 18 and the pull rope 15 are in rolling contact. The roller 18 can support the pull rope 15, thereby preventing the pull rope 15 from rubbing against the base 1 at the corner, which can increase the service life of the pull rope 15 and enable the pull rope 15 to slide smoothly in the middle of the base 1. The bottom of the arc plate 16 is set to an arc shape. The arc shape can open the arc plate 16 when it is squeezed from the bottom, and will not open when the upper part of the arc plate 16 is squeezed, so that the base 1 can be fixed on the wire rack, which can improve the stability of the base 1.
[0037] Working principle: When in use, the limit shell 6 and the rolling shaft 7 can be used to limit the position, so as to prevent friction between the rope and the base 1 when the rope is pulled. When the pressure block 8 is squeezed by the rope, it will drive one end of the pull rope 9 to move. At this time, the limit plate 10 can drive the connecting plate 11 and the clamping plate 12 to approach the falling rope through the pull rope 9, so as to contact the rope and clamp the rope at the same time. At the same time, the compression spring 13 can be compressed when the limit plate 10 moves. When the pressure on the pressure block 8 disappears, the limit plate 10 can drive the connecting plate 11 and the clamping plate 12 away from the rope under the action of the compression spring 13, so as to release the clamping of the pay-off wheel 3.
[0038] Among them, by pulling the hook 5, the bracket 4 can drive the support plate 14 to move. At this time, the pull rope 15 can be pulled, and the pull rope 15 can drive the arc plate 16 to compress the compression spring 17. At this time, the base 1 can be lifted and dropped onto one of the frames in the wire rack. At this time, the bracket 4 is not pulled by external force, and the compression spring 17 can make the two arc plates 16 approach each other, so that the frame can be clamped, and the base 1 can be quickly installed and fixed. At the same time, when the two arc plates 16 are close, the pull rope 15 can be used to pull the bracket 4 downward. At this time, the restriction on the base 1 can be quickly released, and then the base 1 can be conveniently removed, thereby improving the stability of the base 1 when in use, and at the same time, the base 1 can be quickly connected or separated from the wire rack.
[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
