Description

Technical Field

[0001] This utility model relates to the technical field of electrical safety devices, and in particular to a rigid guide rail and a fall protection device. Background Technology

[0002] Transmission towers are a common type of power facility used in the power industry. They are typically built in open outdoor areas to erect transmission cables for power transmission. Because transmission towers operate in complex environments with varying climates and temperatures, maintenance personnel need to periodically climb to the top of the towers to inspect and maintain various electrical components to ensure normal operation.

[0003] To prevent falls and other safety accidents during power maintenance personnel's climbing, fall arrest devices need to be installed on transmission towers and connected to the personnel. These devices typically consist of a guide rail, a fall arrestor, a safety rope, and a safety harness. The guide rail connects directly to the tower, the safety rope connects to the fall arrestor, and the safety harness connects to the personnel. To ensure protective effectiveness, these components are usually made of materials without elasticity. This means that during prolonged climbs, maintenance personnel frequently need to adjust their posture and move their limbs. Furthermore, strong winds can cause the safety rope and fall arrestor to sway, potentially pulling them taut and creating a reverse, rigid pulling force. This interferes with posture adjustments and limb movements, causing discomfort and a potential fall hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a rigid guide rail and a fall protection device to solve the problems of interference with body posture adjustment and hand and foot movements, discomfort caused to power maintenance personnel, and potential safety hazards of falling from heights.

[0005] According to one aspect of the present invention, a rigid guide rail is provided, comprising:

[0006] A rigid housing for being movably fitted onto a transmission tower;

[0007] A connecting structure, one end of which is movably connected to the rigid shell;

[0008] A guide rail body, the other end of which is movably connected to the connecting structure, so that the guide rail body can extend and float relative to the transmission tower; and

[0009] A sliding sleeve, which is slidably fitted onto the guide rail body and is used to connect to the fall arrester via a safety rope.

[0010] In one embodiment, the rigid housing includes a first half-shell, a second half-shell, a pin, and a lock body. One side of the first half-shell is rotatably connected to one side of the second half-shell via the pin, and the other side of the first half-shell is locked or unlocked to the other side of the second half-shell via the lock body.

[0011] In one embodiment, the first half-shell and / or the second half-shell are provided with an arc-shaped protrusion on the sidewall facing the transmission tower, and the arc-shaped protrusion is in sliding contact with the transmission tower.

[0012] In one embodiment, the guide rail body includes a first rail body, a connecting body, and a second rail body. The first rail body is connected and fixed to the second rail body through the connecting body. The first rail body and the connecting body are telescopically and floatingly connected to the rigid shell through the connecting structure. The second rail body is slidably sleeved with the sliding sleeve.

[0013] In one embodiment, the connection structure includes a first flexible component and a second flexible component, the first flexible component being connected to one side of the rigid shell, the first rail and the connector, and the second flexible component being connected to the other side of the rigid shell, the first rail and the connector.

[0014] In one embodiment, both the first flexible component and the second flexible component include a first movable rod, a first elastic telescopic unit, and a second movable rod. One end of the first movable rod is rotatably connected to the rigid shell, and the other end of the first movable rod is rotatably connected to one end of the second movable rod. The other end of the second movable rod is rotatably connected to the connecting body. One end of the first elastic telescopic unit is rotatably connected to the rotatable connection between the first movable rod and the second movable rod, and the other end of the first elastic telescopic unit is rotatably mounted on the first rail.

[0015] In one embodiment, the first elastic telescopic unit includes a first spring and a first gas spring, with the first spring sleeved on the outside of the first gas spring.

[0016] In one embodiment, the connection structure further includes a first support component and a second support component, the first support component and the second support component are arranged in a figure-eight shape, and one end of the first support component and the second support component are fixed to the first rail body, and the other end is in movable contact with the outer wall of the rigid shell.

[0017] In one embodiment, both the first support component and the second support component include a second elastic telescopic unit and a support wheel. One end of the second elastic telescopic unit is disposed on the first rail body, and the other end is connected to the support wheel. The support wheel is rolled on the outer wall of the rigid shell.

[0018] According to another aspect of the present invention, a fall arrest device is also provided, which includes the rigid guide rail as described above.

[0019] When using the rigid guide rail in this solution, the rigid shell is connected to the transmission tower to achieve overall installation of the rigid guide rail on the transmission tower. The sliding sleeve is connected to the fall arrestor via a safety rope, thus enabling connection with the power maintenance personnel wearing the fall arrestor on the other end. When the power maintenance personnel need to adjust their posture or move their hands and feet while climbing the transmission tower, or when strong winds exert a blowing force on the safety rope and fall arrestor, the connection structure between the guide rail body and the rigid shell provides the freedom of expansion and contraction, allowing the guide rail body to elastically float relative to the transmission tower (i.e., the rigid shell). This ensures that the safety rope and fall arrestor, even when taut, still have a certain range of freedom of movement, thus avoiding a reverse, rigid pulling force on the power maintenance personnel. This prevents interference with posture adjustments and hand and foot movements, prevents discomfort for the power maintenance personnel, and eliminates potential fall hazards.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0027] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please refer to Figures 1-3 The rigid guide rail 100 described in one embodiment includes a rigid housing 10 for movably fitting onto a transmission tower 200; a connecting structure 20, one end of which is movably connected to the rigid housing 10; a guide rail body 30, the other end of which is movably connected to the connecting structure 20, so that the guide rail body 30 can extend and float relative to the transmission tower 200; and a sliding sleeve 40, which is slidably fitted onto the guide rail body 30 and is used to connect to a fall arrester via a safety rope.

[0030] When using the rigid guide rail 100 in this solution, the rigid housing 10 is connected to the transmission tower 200 to achieve overall installation of the rigid guide rail 100 onto the transmission tower 200. The sliding sleeve 40 is connected to the fall arrestor via a safety rope, thereby enabling connection with the power maintenance personnel wearing the fall arrestor on the other end. When the power maintenance personnel need to adjust their posture or move their hands and feet while climbing the transmission tower 200, or when strong winds exert a blowing force on the safety rope and fall arrestor, the connecting structure 20 between the guide rail body 30 and the rigid housing 10 provides the freedom of expansion and contraction, allowing the guide rail body 30 to elastically float relative to the transmission tower 200 (i.e., the rigid housing 10). This ensures that the safety rope and fall arrestor, even when taut, still have a certain range of freedom of movement, thus avoiding a reverse hard pulling force on the power maintenance personnel. This prevents interference with posture adjustments and hand and foot movements, prevents discomfort for the power maintenance personnel, and eliminates potential fall hazards.

[0031] Please see Figure 1 In one embodiment, the rigid housing 10 includes a first half-shell 11, a second half-shell 12, a pin 13, and a lock body. One side of the first half-shell 11 is rotatably connected to one side of the second half-shell 12 via the pin 13, and the other side of the first half-shell 11 and the other side of the second half-shell 12 are locked or unlocked by the lock body.

[0032] When the lock body unlocks, the first half-shell 11 and the second half-shell 12 rotate open, facilitating their movement to the outside of the transmission tower 200. Then, the first half-shell 11 and the second half-shell 12 rotate and close, and the lock body engages, locking the first half-shell 11 and the second half-shell 12 together. This ensures the rigid housing 10 is reliably fitted onto the outside of the transmission tower 200, achieving the assembly and fixation of the rigid guide rail 100 with the transmission tower 200. Furthermore, the rigid housing 10 can slide relative to the transmission tower 200, allowing the fall arrestor to move along with the power maintenance personnel as they climb.

[0033] Alternatively, the lock body can be a mechanical lock, an electromagnetic lock, or the like.

[0034] Furthermore, the first half-shell 11 and / or the second half-shell 12 are provided with arc-shaped protrusions on the sidewalls facing the transmission tower 200, and the arc-shaped protrusions slide in contact with the transmission tower 200. The first half-shell 11 and / or the second half-shell 12 slide in contact with the transmission tower 200 through the arc-shaped protrusions, resulting in a small contact area and low sliding friction resistance, thus reducing the load on power maintenance personnel wearing fall arrest devices during climbing operations. Preferably, four arc-shaped protrusions are provided, respectively contacting the sidewalls of the transmission tower 200 in four directions, thereby preventing uneven force distribution from causing the rigid shell 10 to tilt and jam, affecting the smooth movement of the fall arrest device.

[0035] In one embodiment, the guide rail body 30 includes a first rail body 31, a connecting body 32, and a second rail body 33. The first rail body 31 is connected and fixed to the second rail body 33 via the connecting body 32. The first rail body 31 and the connecting body 32 are telescopically and floatingly connected to the rigid shell 10 via the connecting structure 20. The second rail body 33 is slidably connected to the sliding sleeve 40. The guide rail body 30, with its three-part structural design, allows the first rail body 31, the connecting body 32, and the second rail body 33 to be dedicated to connecting and assembling with their corresponding components. A sufficiently large safety distance is formed between the sliding head and the connecting structure 20 to avoid interference during the swaying movement of the guide rail body 30.

[0036] Please see Figure 1 Specifically, the connection structure 20 includes a first flexible component 21 and a second flexible component 22. The first flexible component 21 is connected to one side of the rigid shell 10, the first rail 31, and the connecting body 32, while the second flexible component 22 is connected to the other side of the rigid shell 10, the first rail 31, and the connecting body 32. Therefore, the first flexible component 21 and the second flexible component 22 can provide balanced flexible floating support to the guide rail body 30 from both sides, better adapting to different posture adjustments, hand and foot movements, and the blowing force of strong winds from different directions for power maintenance personnel.

[0037] Please see Figure 2 and Figure 3 It should be noted that in one embodiment, the first track 31 and the second track 33 are both hollow cylindrical structures; in another embodiment, the first track 31 has a rectangular cross-section and the second track 33 is a hollow cylindrical structure.

[0038] In an optional embodiment, both the first flexible component 21 and the second flexible component 22 include a first movable rod 21a, a first elastic telescopic unit 21b, and a second movable rod 21c. One end of the first movable rod 21a is rotatably connected to the rigid housing 10, and the other end of the first movable rod 21a is rotatably connected to one end of the second movable rod 21c. The other end of the second movable rod 21c is rotatably connected to the connecting body 32. One end of the first elastic telescopic unit 21b is rotatably connected to the rotatable connection between the first movable rod 21a and the second movable rod 21c, and the other end of the first elastic telescopic unit 21b is rotatably mounted on the first rail body 31. During operation, the two first elastic telescopic units 21b provide telescopic elasticity, and the first movable rod 21a and the second movable rod 21c reciprocate relative to the rigid housing 10 and the guide rail body 30, thereby providing the floating force required by the guide rail body 30 to avoid or reduce the reverse rigid pulling force generated by the tensioned anti-fall device on the power maintenance personnel.

[0039] For example, the first elastic telescopic unit 21b includes a first spring and a first gas spring, with the first spring sleeved on the outside of the first gas spring. This combined elastic structure of the first spring and the first gas spring provides better telescopic force. On the one hand, it can more effectively reduce or even eliminate the reverse pulling force exerted on power maintenance personnel by the tensioned anti-fall device; on the other hand, it provides more reliable support to the guide rail body 30, ensuring the stability of the guide rail body 30's posture and position, and providing better auxiliary support for power maintenance personnel.

[0040] In addition, the connecting structure 20 also includes a first support component 23 and a second support component 24. The first support component 23 and the second support component 24 are arranged in a V-shape, with one end of the first support component 23 and the second support component 24 fixed to the first rail body 31 and the other end in movable contact with the outer wall of the rigid shell 10. The first support component 23 and the second support component 24 provide lateral support for the guide rail body 30 relative to the transmission tower 200, ensuring the stability of the guide rail body 30 relative to the transmission tower 200, and also providing a guiding effect for the fall arrest device that moves with the power maintenance personnel.

[0041] It should be noted that when power maintenance personnel wearing fall arrest devices climb the transmission tower 200, the rigid housing 10, connecting structure 20, and guide rail body 30 can be stationary on the transmission tower 200, while only the sliding sleeve 40 slides relative to the guide rail body 30. The sliding sleeve 40, safety rope, fall arrest device, etc., move together with the power maintenance personnel. Alternatively, the rigid housing 10, connecting structure 20, guide rail body 30, sliding ring, etc., can move together with the power maintenance personnel relative to the transmission tower 200. The choice can be made according to the needs.

[0042] Furthermore, both the first support assembly 23 and the second support assembly 24 include a second elastic telescopic unit and a support wheel. One end of the second elastic telescopic unit is disposed on the first rail 31, and the other end is connected to the support wheel. The support wheel is rolled on the outer wall of the rigid shell 10. The second elastic telescopic unit further provides telescopic floating force and buffers and reduces shock. The support wheel rolls on the transmission tower 200, supporting the fall arrestor that moves with the power maintenance personnel and reducing frictional resistance.

[0043] According to another aspect of the present invention, a fall arrest device is also provided, which includes the rigid guide rail 100 as described above.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
