Description

Technical Field

[0001] This utility model belongs to the field of transmission line tower construction technology, and in particular, it is a fall prevention safety system for transmission line tower construction. Background Technology

[0002] The safety of construction workers is always a crucial issue during the construction and maintenance of power transmission line towers. Traditional construction methods and existing fall protection systems have certain limitations and shortcomings in practical applications, especially in improving construction safety and work efficiency.

[0003] Most existing fall arrest systems are fixed in place, making it difficult to quickly and safely move them to different work locations according to construction needs. This usually requires manual disassembly and reinstallation of the equipment, a time-consuming and complex process. The inability to flexibly adjust position not only reduces work efficiency but may also force workers to move in dangerous ways. For example, when moving from one tower section to another, the lack of convenient relocation capabilities may force workers to move without proper protection, increasing the risk of falls. Utility Model Content

[0004] The purpose of this utility model is to provide a safety system for preventing falls during the construction of transmission line towers, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fall protection system for the construction of transmission line towers, comprising a transmission line tower assembly, wherein the transmission line tower assembly includes four longitudinal tower frames arranged in a rectangular pattern and multiple horizontal tower beams arranged upwards and welded between the four longitudinal tower frames, wherein a construction fall protection component is hoisted and suspended on one of the horizontal tower beams by an external crane, the construction fall protection component including a frame that sags under its own weight and conforms to the transmission line tower assembly. The system includes a fall arrest support plate, a hook integrally formed on the top of the fall arrest support plate, and multiple fall arrest climbing footboards equidistantly welded to the outer wall of the fall arrest support plate. The hook is hung on the tower beam. A fall arrest safety net box is welded to the bottom outer wall of the fall arrest support plate. The fall arrest safety net box is located below the multiple fall arrest climbing footboards. A displacement drive assembly is provided on the outer wall of the fall arrest support plate near the hook to drive the fall arrest support plate to move along the transverse axis of the tower beam.

[0006] In a preferred embodiment of this design, an opening is provided in the middle of the outer wall of one end of the anti-fall support frame plate near the tower beam, and the displacement drive component is installed in the opening.

[0007] In a preferred embodiment, the displacement drive assembly includes a fixed extension plate welded to the upper part of the opening and located on the outer wall of the fall arrest support plate, a drive wheel rotatably mounted on the bottom surface of the free end of the fixed extension plate, and a drive motor fixed to the top surface of the fixed extension plate.

[0008] In a preferred embodiment, the output axis of the drive motor passes downward through the fixed extension plate and is fixedly connected to the drive wheel, so that the drive motor drives the drive wheel to rotate in the passage.

[0009] In this preferred embodiment, the outer wall of the drive wheel rubs against the outer wall of one of the tower beams to be hung. When the drive motor drives the drive wheel, the drive wheel applies frictional force on the tower beam, thereby driving the fall arrest support plate to move laterally.

[0010] In a preferred embodiment, a lifting ring for use by an external crane is welded to the middle position of the top surface of the outer wall of the hook component.

[0011] In this preferred embodiment, the inner top wall of the hook component is embedded with multiple positioning steel balls that roll and rub against the outer wall of the tower beam. When the drive motor drives the drive wheel to rotate and the drive wheel moves the fall arrest support plate, the positioning steel balls roll inside the hook component, thereby improving the smoothness of the fall arrest support plate's displacement and preventing the fall arrest support plate from getting stuck.

[0012] In this preferred embodiment, the bottom of the fall arrestor box has a welded protective net bottom, and multiple fall arrestor springs are symmetrically installed between the top surface of the protective net bottom and the inner top wall of the fall arrestor box. The fall arrestor springs act as a buffer within the fall arrestor box; when a fall occurs, the impact on the fall arrestor box is reduced by the cushioning effect of the fall arrestor springs.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This fall protection system for power transmission line tower construction integrates fall protection components, including fall protection support plates, hooks, and fall protection climbing footboards, providing a stable working platform for construction workers. In particular, the fall protection net box and its bottom-mounted protective netting, along with multiple symmetrically installed fall protection springs inside, effectively absorb impact and reduce injury in the event of an accidental fall.

[0015] The displacement drive assembly allows the fall arrestor support plate to move along the transverse axis of the tower beam. This enables construction workers to easily adjust their working position according to actual needs, improving work efficiency and flexibility. The fall arrestor support plate naturally conforms to the frame of the transmission line tower assembly under its own weight, and the one-piece molded hook at its top ensures the stable suspension of the entire assembly on the tower beam. This design not only enhances the stability of the overall structure but is also suitable for transmission line towers of different specifications, demonstrating good adaptability.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0026] This embodiment provides, for example Figures 1 to 5 The diagram illustrates a fall protection system for the construction of transmission line towers. It includes a transmission line tower assembly 1, which comprises four rectangularly arranged longitudinal tower frames 2 and multiple upward-arranged horizontal beams 3 welded between the four longitudinal frames 2. A construction fall protection component 4 is hoisted and suspended from one of the horizontal beams 3 by an external crane. The construction fall protection component 4 includes a fall protection support plate 5 that sags under its own weight and adheres to the frame of the transmission line tower assembly 1. The hook 15 is formed on the top of the fall arrest support plate 5 and multiple fall arrest climbing footboards 6 are welded at equal intervals to the outer wall of the fall arrest support plate 5. The hook 15 is hung on the tower beam 3. A fall arrest protection net box 8 is welded to the bottom outer wall of the fall arrest support plate 5. The fall arrest protection net box 8 is located below the multiple fall arrest climbing footboards 6. A displacement drive component is provided on the outer wall of the end of the fall arrest support plate 5 near the hook 15 to drive the fall arrest support plate 5 to move along the horizontal axis of the tower beam 3.

[0027] In this embodiment, an opening 11 is provided in the middle of the outer wall of one end of the fall arrest support plate 5 near the tower beam 3, and the displacement drive component is installed in the opening 11.

[0028] In this embodiment, the displacement drive assembly includes a fixed extension plate 12 welded to the upper part of the opening 11 and located on the outer wall of the fall arrest support plate 5, a drive wheel 13 rotatably mounted on the bottom surface of the free end of the fixed extension plate 12, and a drive motor 14 fixed to the top surface of the fixed extension plate 12.

[0029] In this embodiment, the output axis of the drive motor 14 passes downward through the fixed extension plate 12 and is fixedly connected to the drive wheel 13, so that the drive motor 14 drives the drive wheel 13 to rotate in the port 11.

[0030] In this embodiment, the outer wall of the drive wheel 13 frictionally abuts against the outer wall of one of the tower beams 3 to be hung. When the drive motor 14 drives the drive wheel 13, the drive wheel 13 applies frictional force on the tower beam 3, thereby driving the fall protection support plate 5 to move laterally.

[0031] In this embodiment, a lifting ring 7 for use by an external crane is welded to the middle position of the top surface of the outer wall of the hook 15.

[0032] In this embodiment, multiple positioning steel balls 16 are rolled and embedded in the inner top wall of the hook component 15. The positioning steel balls 16 roll and rub against the outer wall of the tower beam 3. When the drive motor 14 drives the drive wheel 13 to rotate, and the drive wheel 13 drives the fall arrest support plate 5 to move, the positioning steel balls 16 roll inside the hook component 15, thereby improving the smoothness of the displacement of the fall arrest support plate 5 and preventing the fall arrest support plate 5 from getting stuck.

[0033] In this embodiment, the bottom of the fall arrestor box 8 has a protective net bottom 9 welded together with the fall arrestor box 8. Multiple fall arrestor buffer springs 10 are symmetrically installed between the top surface of the protective net bottom 9 and the inner top wall of the fall arrestor box 8. The fall arrestor buffer springs 10 play a cushioning role in the fall arrestor box 8. When a fall occurs, the fall onto the fall arrestor box 8, and the impact is reduced by the cushioning effect of the fall arrestor buffer springs 10.

[0034] Working principle:

[0035] The fall protection system for the construction of this transmission line tower consists of a transmission line tower assembly 1 composed of four rectangular longitudinal frames 2 and multiple tower crossbeams 3 welded upwards between these longitudinal frames. Before construction, the fall protection component 4 is hoisted and hung on a selected tower crossbeam 3 by an external crane. The fall protection component 4 includes a fall protection support plate 5, which naturally sags and adheres to the frame of the transmission line tower assembly 1 under its own weight, and is equipped with hooks 15 for hanging on the tower crossbeams 3, as well as multiple fall protection climbing footboards 6 for workers to use.

[0036] When the fall arrest support plate 5 needs to be moved, the drive motor 14 is started, and its output shaft drives the drive wheel 13 to rotate. The outer wall of the drive wheel 13 frictionally contacts the tower beam 3, and the rotation of the drive wheel 13 moves the fall arrest support plate 5 along the transverse axis of the tower beam 3. During this process, the positioning steel ball 16 rolls and is embedded inside the hook 15, reducing displacement resistance and ensuring smooth movement without jamming. The fall arrest safety net box 8 is located below the fall arrest climbing footboard 6, with a safety net bottom 9 at the bottom, and multiple fall arrest buffer springs 10 are symmetrically installed between the top and bottom. In the event of a fall accident, if a person falls onto the fall arrest safety net box 8, the elasticity of the fall arrest buffer springs 10 will reduce the impact force and provide additional safety.
