Description

Technical Field

[0001] This utility model relates to the field of high-altitude electrical work technology, specifically a safety fall-prevention buffer device for high-altitude electrical work. Background Technology

[0002] In high-altitude electrical work, workers are required to operate from high-altitude poles, towers, cables, and other overhead locations, facing a significant risk of falling. A fall can cause serious personal injury and even endanger the worker's life. Therefore, reliable fall protection devices are crucial for ensuring personnel safety in high-altitude electrical work.

[0003] Currently, to address the risk of falls, workers are typically equipped with safety ropes and buckles. The safety rope connects the worker to the buckle by securing the buckle to a pole or other stable structure, thus providing protection. However, in an actual fall, the worker's weight can cause the safety rope to experience immense tension instantly. If this tension exceeds the rope's load-bearing capacity, it can easily break, rendering the safety rope ineffective.

[0004] To address this issue, existing technologies employ a buffer spring between the safety rope and the buckle, hoping to cushion the impact of a fall through the spring's elastic deformation, thus preventing the safety rope from breaking. However, this single-spring buffer structure has significant shortcomings: firstly, the spring's buffering effect is limited; under significant impact, the spring's deformation quickly reaches its limit, making it difficult to effectively absorb the impact; secondly, the spring is prone to elastic fatigue after prolonged use, leading to a decline in buffering performance. Furthermore, the spring's extension and contraction direction is singular, providing buffering force only along the axial direction, which cannot cope with the multi-directional forces under complex fall conditions, still posing a risk of the safety rope breaking and failing to adequately guarantee the safety of workers.

[0005] Therefore, there is an urgent need for a high-altitude electrical work safety fall protection buffer device with better cushioning effect and higher reliability to make up for the shortcomings of existing technologies. Utility Model Content

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0030] Example

[0031] As shown in Figure 1-4, the high-altitude electrical work safety fall protection buffer device is a key piece of equipment to ensure the life safety of high-altitude workers. Its overall structural design fully considers the complexity of the working environment and safety requirements.

[0032] The device includes a safety rope 2, a buckle 3, and a buffer assembly 4 connecting the two components. The end of the safety rope 2 away from the buffer assembly 4 is fixed to the protective vest 1 by a high-strength stitch. The stitching adopts a double-thread double-stitch process, and the stitch spacing is controlled at 3-5mm to ensure the connection strength.

[0033] The protective vest 1 is made of Kevlar fiber, which has extremely high tensile strength and abrasion resistance, while being lightweight and not placing too much burden on the workers. Adjustable Velcro closures are provided at the shoulders and waist of the protective vest 1, allowing for flexible adjustment to suit different body types, ensuring a secure and comfortable fit. When worn by workers at heights, it provides basic protective support.

[0034] The buffer component 4 is the core part of the entire device that enables the buffer and fall protection function, and its specific structure is as follows:

[0035] The support cylinder 41 is made of die-cast aluminum alloy, featuring light weight and high strength. Its sealed end is fixed to the safety rope 2 with four 5mm diameter stainless steel rivets evenly distributed in a ring to ensure connection stability. The support cylinder 41 is 20-30cm long and has an inner diameter of 8-10cm. It has side holes 42 communicating with its interior, with a length of 15-20cm and a width of 3-4cm. These side holes 42 allow the follower plate 45 to pass through and provide sufficient space for its movement.

[0036] The guide rod 43 is made of high-strength alloy steel with a diameter of 1.5-2cm. It is fixed to the inner wall of the bearing cylinder 41 by welding. The weld joint is ground to ensure a smooth surface and avoid wear on other parts. The guide rod 43 is parallel to the axis of the bearing cylinder 41, and its length matches the length of the bearing cylinder 41.

[0037] The insertion post 44 is also made of aluminum alloy, with a diameter of 6-8cm. One end is inserted into the bearing cylinder 41 through the open end of the bearing cylinder 41, and the other end is fixed to the buckle 3 with bolts of type M8. There are two bolts, symmetrically distributed. The insertion post 44 is 10-15cm long inside the bearing cylinder 41 to ensure sufficient movement distance to achieve a cushioning effect during a fall.

[0038] The follower plate 45 is made of stainless steel with a thickness of 1-1.5cm. It is welded to one end of the insertion post 44 located inside the bearing cylinder 41 and penetrates the bearing cylinder 41 radially. The follower plate 45 has a guide hole that matches the guide rod 43, with a diameter 0.5-1mm larger than the diameter of the guide rod 43. It slides along the length of the bearing cylinder 41 guided by the guide rod 43. A spring 46 is fitted onto the outer surface of the guide rod 43, on the side of the follower plate 45 near the buckle 3. The spring 46 is made of high-strength spring steel with a diameter of 3-4cm, a free length of 8-10cm, and an elastic coefficient that has been precisely calculated to provide appropriate cushioning force during a fall.

[0039] The elastic strip 48 is made of polyurethane elastic material, which has good elasticity and wear resistance, and is fixed to the guide rod 43. The elastic strip 48 is wavy in shape, with a wave height of 2-3cm and a wavelength of 5-6cm, and it protrudes outward along the radial direction of the guide rod 43. The surface of the elastic strip 48 near the safety rope 2 is provided with protrusions to prevent the plug-in post 44 from detaching from the bearing cylinder 41. The protrusions are 0.5-1cm high and evenly distributed. The surface of the elastic strip 48 near the buckle 3 is smooth to reduce friction with the follower plate 45.

[0040] The guide rod 43 has a accommodating cavity 47 on its periphery. The accommodating cavity 47 has a depth of 1-1.5cm and a width of 3-4cm. The two ends of the elastic strip 48 are fixed to the two ends of the accommodating cavity 47 with glue. The fixing points are reinforced to ensure that the elastic strip 48 will not fall off when subjected to force.

[0041] When the follower plate 45 moves along the guide rod 43 to the elastic strip 48, the elastic strip 48 exerts a compressive force on the follower plate 45 in the radial direction toward the insertion post 44. In the event of a fall, the worker falls downwards, causing the protective vest 1 to move downwards, and the safety rope 2 to tighten. At this time, the buckle 3 is fixed at the fixed point, and the insertion post 44 moves outwards relative to the bearing cylinder 41. The follower plate 45 slides along the guide rod 43 away from the safety rope 2, and the spring 46 is compressed, generating a certain amount of buffering force. When the follower plate 45 moves to the elastic strip 48, the wavy structure of the elastic strip 48 exerts a radial compressive force on the follower plate 45, further dissipating the energy generated by the fall and providing secondary buffering. Simultaneously, the protrusions on the elastic strip 48 prevent the follower plate 45 from moving excessively, avoiding the insertion post 44 from detaching from the bearing cylinder 41 and ensuring the safety of the device.

[0042] This application utilizes the elastic strip 48 to create a radial pressure on the follower plate 45 towards the insertion post 44 when the follower plate 45 moves along the guide rod 43 to the elastic strip 48, thereby providing cushioning and significantly improving the cushioning effect. Compared with traditional cushioning devices, this device, through the dual cushioning effect of the spring 46 and the elastic strip 48, can more effectively absorb the impact force generated during a fall, reducing injury to workers. Furthermore, the materials and dimensions of each component have been carefully selected and designed to ensure the strength and reliability of the device, enabling it to function effectively in various complex high-altitude electrical work environments.

[0043] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
