Description

Technical Field

[0001] This utility model relates to the field of safety equipment technology, specifically to a high-altitude fall protection safety system. Background Technology

[0002] In the field of high-altitude work safety, fall arrest systems are crucial equipment for ensuring personnel safety. Existing systems typically use a safety rope connected to a mobile vehicle to provide protection. To prevent the safety rope from twisting during worker movement, a vertical pivot is commonly installed at the upper end of the rope, forming a rotating connection with the mobile vehicle. To ensure convenient installation of the pivot and prevent it from falling downwards, a locking nut is traditionally installed at the upper end. However, this structure has significant drawbacks in practical use: the nut is prone to loosening under long-term vibration and rotation. Once loosened, the pivot will fail to hold, causing the entire fall arrest system to malfunction, seriously threatening the lives of workers at height. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a high-altitude fall protection safety system.

[0004] This utility model is achieved through the following technical solution, providing a high-altitude fall protection safety system, including a safety rope, a longitudinal guide rail, and a longitudinal traverse vehicle that moves on the longitudinal guide rail. The longitudinal traverse vehicle includes a vertical plate, a stepped shaft, and traveling wheels mounted on the upper part of the vertical plate. A lifting ring is fixed to the lower end of the stepped shaft, and the upper end of the safety rope is connected to the lifting ring. The stepped shaft includes a large-diameter section and a small-diameter section arranged vertically. A pressure plate is bolted to one side of the vertical plate, and the pressure plate and the vertical plate wrap around the small-diameter section of the stepped shaft.

[0005] In this design, the upper end of the safety rope is connected to the lifting ring, and the lower end is connected to the safety belt of the worker. When the worker moves longitudinally, the safety rope pulls the traverse vehicle along the longitudinal guide rail. In the event of a fall, the safety rope provides safety protection. When the worker turns and twists the safety rope, the stepped shaft can rotate freely between the upright plate and the pressure plate, preventing the safety rope from twisting. This design uses a stepped shaft to achieve a rotating connection with the upright plate, which is convenient to install and maintain, and effectively avoids loosening of the threads.

[0006] As an optimization, the upright plate has a clearance opening to avoid the large-diameter section. This clearance opening in the design prevents interference friction between the upright plate and the large-diameter section.

[0007] As an optimization, the pressure plate has an arc-shaped groove on its side that fits the small-diameter section. In this design, the arc-shaped groove fits snugly against the small-diameter section, achieving a better wrapping effect.

[0008] As an optimization, the pressure plate includes flat plates at both ends and an arc-shaped plate in the middle. The inner side of the arc-shaped plate is adapted to the small-diameter section, and the flat plates are fixed to the upright plate by bolts. In this design, the arc-shaped plate achieves the wrapping of the outer ring of the small-diameter section.

[0009] As an optimization, a wear-resistant ring is fitted onto the smaller diameter section above the pressure plate. The wear-resistant ring in this design serves to resist wear and is easy to replace, preventing wear on the stepped shaft.

[0010] As an optimization, a horizontal mounting beam is fixed to the upper end of the upright plate, and axles are fixed to both ends of the mounting beam. Each axle has a traveling wheel axled to both ends. In this design, the mounting beam and two axles enable the movement of the four traveling wheels on the longitudinal guide rail.

[0011] As an optimization, two lateral moving vehicles are connected to the longitudinal guide rail, and the two lateral moving vehicles move on two transverse guide rails respectively. When the worker moves laterally, the longitudinal guide rail and the lateral moving vehicles are pulled on the transverse guide rails by a safety rope, thereby achieving follow-up with the worker.

[0012] As an optimization, track wheels are mounted at both ends of the transverse guide rail, and these track wheels travel on a fixed track. The position of the entire safety system can be adjusted by moving the track wheels at both ends of the transverse guide rail along the fixed track, thus adapting to different work positions.

[0013] The beneficial effects of this utility model are as follows: This high-altitude fall protection safety system, through a special structure combining a stepped shaft and a pressure plate, completely eliminates the traditional nut fixing method, fundamentally eliminating the safety hazards caused by loose nuts. The large-diameter section of the stepped shaft naturally forms an axial limit, while the small-diameter section is jointly wrapped by the vertical plate and the bolt-fixed pressure plate, ensuring that the shaft will not fall downwards while allowing it to rotate freely. This design not only solves the problem of safety rope torsion, allowing workers to turn freely without rope entanglement, but also greatly improves the reliability and safety of the system. At the same time, the overall structural layout is reasonable, installation and maintenance are simple, and the position can be flexibly adjusted as personnel move. In the event of a fall, it can provide timely protection, significantly improving the safety level of high-altitude operations, and has significant practical value and promotional significance.

[0015] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0016] like Figures 1-7 As shown, the present invention provides a high-altitude fall protection safety system, including a safety rope 5, a longitudinal guide rail 2, and a longitudinal traverse vehicle 1 that moves on the longitudinal guide rail 2. The lower end of the safety rope 5 is connected to the safety belt of the high-altitude worker, and the upper end is connected to the longitudinal traverse vehicle 1, which enables passive following.

[0017] The longitudinal transfer vehicle 1 includes a vertical plate 11 and traveling wheels 17 mounted on the upper end of the vertical plate 11, such as Figure 4 , 5 As shown, four wheels 17 are installed on the upper end of the upright plate 11 of each longitudinal transfer vehicle 1. In order to achieve the installation of the four wheels 17, a horizontal mounting beam 16 is fixedly connected to the upper end of the upright plate 11 in this embodiment. The length direction of the mounting beam 16 is parallel to the length direction of the longitudinal guide rail 2. Both ends of the mounting beam 16 are fixedly connected to axles 18, and both ends of the axles 18 are axially connected to wheels 17.

[0018] like Figure 4 As shown, the longitudinal guide rail 2 is a hollow structure, and the four wheels 17 travel on the bottom surface inside the hollow structure, with the upright plate 11 extending out of the longitudinal guide rail 2.

[0019] To prevent the safety rope 5 from twisting, the connection point between the safety rope 5 and the longitudinal transfer vehicle 1 needs to be able to rotate. Therefore, the longitudinal transfer vehicle 1 in this embodiment also includes a vertical stepped shaft 12. The stepped shaft 12 includes a large-diameter section and a small-diameter section arranged vertically. The stepped shaft 12 can be a one-piece machined part or it can be machined separately and then fixedly connected.

[0020] A lifting ring 13 is fixedly connected to the lower end of the stepped shaft 12. In this embodiment, the stepped shaft 12 and the lifting ring 13 are integrally formed parts, generally formed by casting or forging. The upper end of the safety rope 5 is connected to the lifting ring 13.

[0021] A pressure plate 14 is bolted to one side of the upright plate 11. The pressure plate 14 and the upright plate 11 enclose the small-diameter section of the stepped shaft 12. This allows the lower end face of the large-diameter section to be supported on the pressure plate 14 and the upright plate 11. To achieve this enclosing effect, the upright plate 11 has a clearance opening to avoid the large-diameter section, allowing the small-diameter section to fit snugly against the upright plate 11. To enhance the fit, an arc-shaped groove adapted to the small-diameter section is formed on the side of the pressure plate 14; this arc-shaped groove is semi-circular. The pressure plate 14 includes flat plates at both ends and an arc-shaped plate in the middle. The inner side of the arc-shaped plate is semi-circular and adapts to the small-diameter section. The flat plates are fixed to the upright plate 11 by bolts. Therefore, the arc-shaped plate and the arc-shaped groove form a circular space, achieving the enclosing of the small-diameter section.

[0022] To prevent long-term wear between the lower end face of the large-diameter section and the pressure plate 14 and the vertical plate 11, a wear-resistant ring 15 is fitted on the small-diameter section above the pressure plate 14 in this embodiment. The wear-resistant ring 15 can be made of tin bronze, which has good wear resistance.

[0023] The longitudinal guide rail 2 can be fixed, which can realize the follow-up protection of personnel moving in the longitudinal direction. Alternatively, two transverse moving cars 3 can be connected to the longitudinal guide rail 2, and the two transverse moving cars 3 can move on two transverse guide rails 4 respectively, thereby realizing the follow-up protection of personnel moving in the transverse direction and improving the working range of personnel.

[0024] In the above scenario, track wheels 6 can also be installed at both ends of the transverse guide rail 4, with the track wheels 6 moving on a fixed track 7. This allows for position adjustment of the entire high-altitude fall protection safety system by manually moving the transverse guide rail 4 or by having it moved using a motor.

[0025] How to use this utility model: In use, the upper end of the safety rope 5 is connected to the lifting ring 13, and the lower end of the safety rope 5 is connected to the safety belt of the worker. When the worker moves longitudinally, the safety rope 5 pulls the longitudinal trolley 1 to move on the longitudinal guide rail 2. When the worker moves laterally, the safety rope 5 pulls the longitudinal guide rail 2 and the lateral trolley 3 to move on the lateral guide rail 4, thus achieving the following movement with the worker. Alternatively, the travel wheels 6 at both ends of the lateral guide rail 4 can move on the fixed travel track 7 to achieve the position adjustment of the entire safety system, thus corresponding to different working positions. When a person accidentally falls, the safety rope 5 provides safety protection. When the worker turns around and causes the safety rope 5 to twist, the step shaft 12 can rotate freely between the upright plate 11 and the pressure plate 14 to prevent the safety rope 5 from twisting.

[0026] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
