Abstract
Description
Technical Field
[0001] This utility model relates to the field of fall protection for aerial work platforms, specifically a fall-proof aerial work platform. Background Technology
[0002] Fall protection structures for aerial work platforms typically consist of guardrails, with a fall arrestor bar at the top. This fall arrestor bar is hooked to the hooks on the fall arrestor vest. The bottom of the fall arrestor bar is usually welded with a sheet-like reinforcing rib connected to the guardrail to enhance its installation strength. The hook needs to be manually adjusted to align the groove on the hook with the sheet-like reinforcing rib, allowing for unobstructed hook movement. This method is relatively inconvenient for workers to move around. Utility Model Content
[0003] The purpose of this utility model is to provide a fall-proof high-altitude work platform in order to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fall-prevention high-altitude work platform, including a guardrail, a rotating door rotatably installed at one end of the guardrail, multiple fixed rods fixedly installed at the top of the guardrail, and fall-prevention rods distributed along the trajectory of the guardrail fixedly installed at the top of the fixed rods. The fall-prevention rods do not extend above the rotating door, and a groove assembly is provided inside the fall-prevention rod. A hook assembly is movably connected to the inner wall of the groove assembly.
[0005] As a further embodiment of this utility model: the groove assembly includes a through groove and a sliding groove extending along the distribution trajectory of the fall arresting rod. The through groove and the sliding groove are connected, and end plates are welded to both ends of the fall arresting rod. The bottom end of the end plate is fixedly connected to the top end of the guardrail, and the openings at both ends of the through groove and the sliding groove are closed by the end plate.
[0006] As a further embodiment of this utility model: the hook assembly includes a slider with a spherical structure, the slider being movably connected to the inner cavity of the groove, and one end of the slider being integrally formed with a connecting rod with a columnar structure, the connecting rod passing through a through groove to the outside of the anti-fall rod.
[0007] As a further embodiment of this utility model: the hook assembly further includes a rotating groove formed at one end of the connecting rod, a rotating rod rotatably mounted on the inner wall of the rotating groove, one end of the rotating rod extending through to the outside of the connecting rod, and a connecting ring with an annular structure integrally formed at the end of the connecting rod away from the slider.
[0008] As a further improvement of this utility model, the cross-sections of both the rotating groove and the rotating rod are convex.
[0009] Compared with the prior art, the beneficial effects of this utility model are: By setting up the tank assembly and the hook assembly, the hook can drive the hook assembly to move freely along the tank assembly without any obstruction, eliminating the need for manual adjustment by staff and thus improving work efficiency.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0013] Please see Figures 1-4 In this embodiment of the utility model, a fall-prevention high-altitude work platform includes a guardrail 1, a rotating door 2 rotatably installed at one end of the guardrail 1, a plurality of fixed rods 5 fixedly installed at the top of the guardrail 1, and fall-prevention rods 4 distributed along the trajectory of the guardrail 1 fixedly installed at the top of the fixed rods 5. The fall-prevention rods 4 do not extend above the rotating door 2, and a groove assembly is provided inside the fall-prevention rods 4. A hook assembly is movably connected to the inner wall of the groove assembly.
[0014] In this embodiment: After the worker enters the protective fence 1, the hook of the fall protection vest worn on the body is connected to the hooking component. During the high-altitude operation, as the worker moves inside the protective fence 1, the hooking component can be pulled to move within the trough component. During the movement, there will be no obstruction, and there is no need to adjust the connection between the hook and the hooking component due to obstruction during the movement, which has a more convenient use effect.
[0015] Please refer to this carefully. Figure 3 and Figure 4 The trough assembly includes a through groove 6 and a slide groove 11 extending along the distribution trajectory of the fall arrestor bar 4. The through groove 6 and the slide groove 11 are connected, and end plates 3 are welded to both ends of the fall arrestor bar 4. The bottom end of the end plate 3 is fixedly connected to the top end of the guardrail 1. The openings at both ends of the through groove 6 and the slide groove 11 are closed by the end plate 3. The hook assembly includes a slider 7 with a spherical structure. The slider 7 is movably connected to the inner cavity of the slide groove 11. One end of the slider 7 is integrally formed with a connecting rod 8 with a columnar structure. The connecting rod 8 passes through the through groove 6 to the outside of the fall arrestor bar 4. The hook assembly also includes a rotating groove opened at one end of the connecting rod 8. A rotating rod 10 is rotatably installed on the inner wall of the rotating groove. One end of the rotating rod 10 passes through to the outside of the connecting rod 8. The end of the connecting rod 8 away from the slider 7 is integrally formed with a connecting ring 9 with an annular structure.
[0016] In this embodiment: After the worker enters the guardrail 1, the hook is connected to the connecting ring 9. Then, when the worker walks inside the guardrail 1, the hook can pull the connecting ring 9. The connecting ring 9 pulls the connecting rod 8 through the rotating rod 10. The moving connecting rod 8 pulls the spherical slider 7 to slide in the slide groove 11. The slide groove 11 and the through groove 6 are continuous, so there will be no obstruction during the sliding process. Since the openings at both ends of the slide groove 11 and the through groove 6 are closed by the end plate 3, the slider 7 and the connecting rod 8 can be prevented from separating from the fall arresting rod 4.
[0017] Please refer to this carefully. Figure 4 Both the rotating groove and the rotating rod 10 have a "convex" shaped cross-section.
[0018] In this embodiment: by setting the rotating rod 10, the angle of the connecting ring 9 can be adjusted during the process of the connecting ring 9 being hooked to facilitate use by different workers, and the "convex" structure of the rotating groove and the rotating rod 10 can prevent the rotating rod 10 from detaching.
[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
