Description

Technical Field

[0001] This utility model relates to the field of tower maintenance technology, and in particular to a foot-operated anti-slip support structure for tower maintenance. Background Technology

[0002] In fields such as power transmission and communication signal transmission, iron towers are usually required as supporting carriers for laying cables. In order to ensure the safe and stable operation of communication, power and other infrastructure, iron towers usually need to be inspected regularly. During this process, maintenance personnel often need to stand on the iron tower and perform maintenance work by using foot support structures.

[0003] Chinese patent CN217872616U discloses a safety protection platform for climbing towers. The key technical features are: a U-shaped round rod with an anti-slip mechanism on its inner side. This anti-slip mechanism includes an inner reinforcing rod, whose front and rear ends are fixedly connected to the right sides of the inner front and rear ends of the U-shaped round rod. The left sides of the inner front and rear ends of the U-shaped round rod are fixedly connected to the front and rear ends of an outer reinforcing rod. A rod body is fixedly connected to the left side of the middle portion of the inner reinforcing rod, and the left end of the middle portion of the rod body is fixedly connected to the middle portion of the outer reinforcing rod. In this invention, the anti-slip mechanism prevents the entire platform from slipping, while also making the structure more stable. Combined with the U-shaped handrail, it provides handholds during climbing. The semi-circular arrangement on the outer side adds attachment points for safety belts or large safety hooks, providing reliable moving attachment points for construction or maintenance personnel climbing up and down.

[0004] Existing technologies often have the following drawbacks: When maintenance pedals are stepped on, the lack of a stopper at the edge makes it easy for maintenance personnel to slip and miss the pedal, resulting in poor maintenance safety.

[0005] Therefore, this utility model provides a foot pedal anti-slip support structure for tower maintenance. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that in the existing technology, the maintenance pedals are prone to slipping and falling when stepped on because the edges lack a restraining component, resulting in poor maintenance safety. Therefore, this utility model proposes an anti-slip support structure for tower maintenance foot pedals.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a foot pedal anti-slip support structure for tower maintenance, including a foot pedal, two handrails fixedly connected to the upper surface of the foot pedal, a first moving block and a second moving block slidably connected to the surfaces of the two handrails, the first moving block and the second moving block being respectively disposed at both ends of the handrails, and a stop bar fixedly connected to the side of the first moving block and the second moving block that are close to each other, the stop bar being disposed on the side of the two handrails that are close to each other.

[0008] The effect achieved by the above components is as follows: by setting the first and second moving blocks, the stop bar and the handrail can be connected at the same time, ensuring that the stop bar can move closer to or away from the foot pedal. During maintenance work, the stop bar can restrict the position of the maintenance personnel and avoid slipping and stepping into the air due to stepping on the edge of the foot pedal as much as possible.

[0009] Preferably, a connecting rod is fixedly connected to the side of the first moving block and the second moving block that are close to each other. The connecting rod is disposed between the handrail and the foot pedal. A side plate is fixedly connected to the side of the first moving block that is away from the connecting rod.

[0010] The effect achieved by the above components is that, through the linkage rod, the movement of the first moving block can drive the second moving block to move synchronously.

[0011] Preferably, a toothed plate is fixedly connected to the side of the side plate away from the first moving block, and two gears are rotatably connected to the side of the foot pedal near the toothed plate, with the toothed plate meshing with the gears.

[0012] The effect achieved by the above components is that, through the toothed plate and gears, the accuracy of the position adjustment of the side plate and the first moving block can be improved during their movement, and the position of the side plate and the first moving block can be easily restricted.

[0013] Preferably, two first sliding grooves are provided on the side of the foot pedal near the gear, and the first sliding grooves on the two foot pedals are all located on the side of the gear away from the gear plate. The surfaces of the first sliding grooves on the two foot pedals are slidably connected to first sliders. Two limiting plates are slidably connected on the side of the foot pedal near the gear, and the two limiting plates are fixedly connected to the first sliders.

[0014] The effect achieved by the above components is that the limiting plate can be connected to the foot pedal through the first slider, and the limiting plate can move closer to or away from the gear, thereby restricting and releasing the rotation of the gear.

[0015] Preferably, two fixing plates are fixedly connected to the side of the foot pedal near the gear, and control rods are slidably connected to the inner walls of the two fixing plates. A control plate is fixedly connected to the end of the control rod near the limit plate, and the control plate is fixedly connected to the limit plate.

[0016] The above components achieve the following effects: the position of the limit plate can be easily adjusted by the control lever and control plate, and the stability of the moving limit plate can be improved by the fixed plate.

[0017] Preferably, a circular plate is fixedly connected to the surface of the control rod, the circular plate is disposed on the side of the fixed plate away from the limiting plate, a closed cylinder is sleeved on the surface of the circular plate, the closed cylinder is fixedly connected to the side of the fixed plate away from the limiting plate, a spring is sleeved on the surface of the control rod, the spring is disposed inside the closed cylinder, and the two ends of the spring are fixedly connected to the circular plate and the closed cylinder respectively.

[0018] The above components achieve the following effects: the enclosed cylinder, circular plate, and spring can restrict the position of the control lever; the enclosed cylinder can also shield and seal the spring, minimizing the risk of corrosion.

[0019] Preferably, two second sliding grooves are provided on the side of the foot pedal near the control lever, and a second slider is slidably connected to the surface of each of the two second sliding grooves on the foot pedal. A limit strip is fixedly connected to the side of the second slider near the control lever, and a limit plate is fixedly connected to the end of the control lever near the limit strip.

[0020] The effect achieved by the above components is as follows: the limit strip can be connected to the foot pedal by the second slider, while ensuring that the limit strip can move relative to the foot pedal. The limit strip and the limit plate can restrict the position of the control lever.

[0021] In summary: 1. In this utility model, by setting the first moving block, the second moving block and the stop bar, the position of the maintenance personnel's legs can be restricted when the maintenance personnel step on the foot pedal, thereby avoiding the maintenance personnel stepping on the edge of the foot pedal as much as possible, reducing the risk of slipping and falling, and thus improving the safety during the maintenance process.

[0022] 2. In this utility model, the position of the stop bar can be easily adjusted by the setting of the limiting plate, gear, toothed plate and side plate, so that the stop bar can be easily moved closer to the foot pedal when the foot pedal is not needed, so that maintenance personnel can easily grab the handrail to climb the tower.

Detailed Implementation

[0025] Reference Figure 1 As shown, this utility model provides a technical solution: a foot pedal anti-slip support structure for tower maintenance, including a foot pedal 1. Two handrails 2 are fixedly connected to the upper surface of the foot pedal 1. A first moving block 3 and a second moving block 4 are slidably connected to the surfaces of both handrails 2. The first moving block 3 and the second moving block 4 are respectively located at both ends of the handrails 2. A stop bar 5 is fixedly connected to the side of the first moving block 3 and the second moving block 4 that is close to each other. The stop bar 5 is located on the side of the two handrails 2 that is close to each other. Through the first moving block 3 and the second moving block 4, the stop bar 5 can be connected to the handrails 2 while ensuring that the stop bar 5 can move closer to or away from the foot pedal 1. During maintenance work, the stop bar 5 can restrict the position of the maintenance personnel, minimizing the risk of slipping and falling due to stepping on the edge of the foot pedal 1.

[0026] The following is a detailed explanation of its overall setup and function.

[0027] Reference Figures 1-5As shown in this embodiment: a connecting rod 6 is fixedly connected to the side of the first moving block 3 and the second moving block 4 that are close to each other. The connecting rod 6 is located between the handrail 2 and the foot pedal 1. A side plate 7 is fixedly connected to the side of the first moving block 3 that is away from the connecting rod 6. Through the connecting rod 6, the movement of the first moving block 3 can drive the second moving block 4 to move synchronously. A toothed plate 8 is fixedly connected to the side plate 7 that is away from the first moving block 3. Two gears 9 are rotatably connected to the side of the foot pedal 1 that is close to the toothed plate 8. The toothed plate 8 meshes with the gears 9. Through the toothed plate 8 and the gears 9, the position adjustment accuracy of the side plate 7 and the first moving block 3 can be improved during their movement, and the positions of the side plate 7 and the first moving block 3 can be easily restricted. Two first sliding grooves are formed on the side of the foot pedal 1 near the gear 9. Both first sliding grooves on the foot pedal 1 are located on the side of the gear 9 away from the gear plate 8. First sliders 11 are slidably connected to the surfaces of the first sliding grooves on both foot pedals 1. Two limiting plates 10 are slidably connected to the side of the foot pedal 1 near the gear 9, and both limiting plates 10 are fixedly connected to the first sliders 11. Through the first sliders 11, the limiting plates 10 can be connected to the foot pedal 1, and the limiting plates 10 can move closer to or further away from the gear 9, thereby restricting and releasing the rotation of the gear 9.

[0028] Two fixing plates 13 are fixedly connected to the side of the foot pedal 1 near the gear 9. Control rods 14 are slidably connected to the inner walls of both fixing plates 13. A control plate 12 is fixedly connected to the end of the control rod 14 near the limit plate 10, and the control plate 12 is fixedly connected to the limit plate 10. The control rods 14 and control plates 12 allow for easy adjustment of the position of the limit plate 10, and the fixing plates 13 improve the stability of the moving limit plate 10. A circular plate 20 is fixedly connected to the surface of the control rod 14, located on the side of the fixing plate 13 away from the limit plate 10. A closed cylinder 15 is fitted onto the surface of the circular plate 20, fixedly connected to the side of the fixing plate 13 away from the limit plate 10. A spring 16 is fitted onto the surface of the control rod 14, located inside the closed cylinder 15, with both ends of the spring 16 fixedly connected to the circular plate 20 and the closed cylinder 15, respectively. The enclosed cylinder 15, circular plate 20, and spring 16 restrict the position of the control lever 14. The enclosed cylinder 15 also shields and seals the spring 16, minimizing the risk of corrosion. Two second sliding grooves are provided on the side of the foot pedal 1 closest to the control lever 14. Second sliders 18 are slidably connected to the surfaces of these grooves. A limit strip 19 is fixedly connected to the side of the second slider 18 closest to the control lever 14, and a limit plate 17 is fixedly connected to the end of the control lever 14 closest to the limit strip 19. The second sliders 18 connect the limit strip 19 to the foot pedal 1 while allowing the limit strip 19 to move relative to the foot pedal 1. The limit strip 19 and limit plate 17 effectively restrict the position of the control lever 14.

[0029] Working principle: When maintenance personnel step on foot pedal 1 to perform tower maintenance, firstly, the limiting strip 19 moves, causing the second slider 18 to slide on the surface of the second groove on foot pedal 1. This moves the limiting strip 19 away from the limiting plate 17, preventing it from obstructing the movement of the limiting plate 17. Then, the control plate 12 moves, causing the limiting plate 10 to move away from the gear 9, releasing the restriction on the rotation of the gear 9. During this process, the control plate 12 moves the control rod 14 and the circular plate 20 to slide on the inner walls of the fixed plate 13 and the enclosed cylinder 15. At the same time, the first slider 11 slides on the surface of the first groove on foot pedal 1. When the limiting strip 19 is between the fixed plate 13 and the limiting plate 17, the limiting strip 19 is released, and under the action of gravity... The limit bar 19 moves back to its original position, the control plate 12 is released, and under the action of the spring 16, the limit plate 17 moves closer to the limit bar 19, which restricts the position of the limit plate 10. Then, the stop bar 5 is moved away from the foot pedal 1. At the same time, the first moving block 3 drives the second moving block 4 to move synchronously on the surface of the handrail 2 through the connecting rod 6. The first moving block 3 drives the toothed plate 8 to move through the side plate 7, so that the gear 9 rotates on the surface of the foot pedal 1. After the position of the stop bar 5 is adjusted, the limit bar 19 is moved away from the limit plate 17. Under the action of the spring 16, the control plate 12 drives the limit plate 10 to move closer to the gear 9, which restricts the rotation of the gear 9. Then, maintenance work can be carried out. By setting the first moving block 3, the second moving block 4, and the stop bar 5, the position of the maintenance personnel's legs can be restricted when they step on the foot pedal 1, thereby minimizing the risk of them stepping on the edge of the foot pedal 1, reducing the risk of slipping and falling, and improving safety during the maintenance process. By setting the limit plate 10, gear 9, toothed plate 8, and side plate 7, the position of the stop bar 5 can be easily adjusted, so that when the foot pedal 1 is not needed, the stop bar 5 can be easily moved closer to the foot pedal 1, making it easier for maintenance personnel to grab the handrail 2 and climb the tower.
