Description

Technical Field

[0001] This utility model relates to the technical field of protective equipment for steel cable chain components, and more specifically, to a vertical steel cable chain anti-sway structure. Background Technology

[0002] Steel cable carriers consist of several units and are used to pull and protect cables. They can be installed horizontally or vertically. Vertical steel cable carriers are mainly used in equipment such as stacker cranes that require height lifting. These types of equipment have long vertical lifting heights, requiring steel cable carriers to pull and protect the equipment cables. Existing vertical steel cable carriers mostly use unidirectional steel cable carrier fixing grooves to limit the vertical steel cable carrier, but the limiting effect is not good enough. In actual operation, the steel cable carrier still swings when the equipment starts and stops, which has a certain impact on the service life and stability of the steel cable carrier. In severe cases, it can cause the steel cable carrier to break and the equipment to stop operating. Utility Model Content

[0003] The purpose of this invention is to provide a vertical steel cable chain anti-sway structure. This anti-sway structure can move up and down to limit the bending position of the vertically suspended steel cable chain, which has a good anti-sway effect and can effectively improve the service life and stability of the steel cable chain, thereby improving the safety and reliability of high-altitude operations.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A vertical steel cable chain anti-sway structure includes a vertically suspended steel cable chain disposed inside a concave fixing groove. The inner ends of both sides of the concave fixing groove are machined with vertically penetrating slots, and the slots are machined with vertically arranged teeth at equal intervals. The lower curved area of ​​the steel cable chain is provided with an upper stabilizing roller and a lower stabilizing roller, respectively, which are symmetrically arranged and penetrate the surface cover plate of the steel cable chain. One side of the upper stabilizing roller and the other side of the lower stabilizing roller are machined with circular anti-sway baffles. A rotating shaft is connected outward from the center of the outer side of the anti-sway baffle of the upper stabilizing roller. The outer end of the rotating shaft is fixedly connected to the inner rotating part of a rotating bearing seat via a nut. Both ends of the outer non-rotating part of the outer ring of the rotating bearing seat are connected inward to rotating sleeves via L-shaped connecting rods.

[0006] As a further optimization of this solution, a gear is fitted on the outer side of the rotating sleeve, and the gear engages with the vertically arranged tooth grooves inside the through groove.

[0007] As a further optimization of this solution, a connecting column is connected outward at the center of the other side of the upper stabilizing roller. The connecting column is connected to the rotating shaft on the other side of the lower stabilizing roller via a transmission belt. An anti-overrun baffle with a diameter larger than the connecting column is machined at the outer end of the connecting column.

[0008] As a further optimization of this solution, the radius of the anti-sway baffle is larger than the radius of the upper stabilizing roller and contacts the side of the steel cable chain. When the steel cable chain is lifted or lowered, it drives the anti-sway baffle to rotate in both directions.

[0009] As a further optimization of this solution, the upper and lower stabilizing rollers slide up and down in the tooth grooves through the gears on both sides, following the up-and-down synchronous movement of the curved area at the lower end of the steel drag chain.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0011] This invention utilizes an upper and lower stabilizing roller structure, which respectively contact and drive the steel cable chain above and below the curved area at its lower end. When the steel cable chain is lifted or lowered, the side-mounted anti-sway baffles rotate in both directions, simultaneously causing the upper and lower stabilizing rollers to move synchronously up and down along the concave fixing groove, following the curved area at the lower end of the steel cable chain. During this process, the anti-sway baffles on both sides can limit the movement of the inner steel cable chain, reducing swaying during its movement. This provides a good anti-sway effect, effectively improving the service life and stability of the steel cable chain, and enhancing the safety and reliability of the aerial work platform.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0017] To address the issue that existing vertical steel cable carriers often use unidirectional steel cable carrier fixing grooves to limit the vertical steel cable carrier, which is not effective enough, the steel cable carrier still swings during equipment startup and shutdown. This affects the service life and stability of the steel cable carrier and can even cause it to break or stop operating.

[0018] like Figure 1 As shown, this application includes a vertically suspended steel cable chain 1 disposed inside a concave fixing groove 2. The inner ends of both sides of the concave fixing groove 2 are machined with vertically penetrating through grooves, and the through grooves are machined with vertically arranged toothed grooves 3 at equal intervals. The upper and lower sides of the lower bending area of ​​the steel cable chain 1 are respectively provided with an upper stabilizing roller 4 and a lower stabilizing roller 5 with a structure that is symmetrical to each other and penetrates the surface cover plate of the steel cable chain 1.

[0019] like Figure 2 As shown, a circular anti-sway baffle 6 is machined on one side of the upper stabilizing roller 4 and the other side of the lower stabilizing roller 5. A rotating shaft 7 is connected outward from the center of the outer side of the anti-sway baffle 6 of the upper stabilizing roller 4. The outer end of the rotating shaft 7 is fixedly connected to the inner ring rotating part 9 of the rotating bearing seat through a nut 8. Both ends of the outer side of the non-rotating part 10 of the outer ring of the rotating bearing seat are connected inward to a rotating sleeve 12 through an L-shaped connecting rod 11. A gear 13 is fitted on the outer side of the rotating sleeve 12. The gear 13 meshes with the vertically arranged tooth groove 3 inside the through groove.

[0020] like Figure 3 As shown, a connecting column 16 is connected outward at the center of the other side of the upper stabilizing roller 4. The connecting column 16 is connected to the rotating shaft 7 on the other side of the lower stabilizing roller 5 via a transmission belt 12. An anti-overrun baffle 14 with a diameter larger than the connecting column 16 is machined on the outer end of the connecting column 16.

[0021] Specifically, the anti-sway baffle 6 has a larger radius than the upper stabilizing roller 4 and contacts the side of the steel cable chain 1. When the steel cable chain 1 is raised or lowered, it drives the anti-sway baffle 6 to rotate in both directions. The upper stabilizing roller 4 and the lower stabilizing roller 5 slide up and down in the tooth groove 3 through the gears 13 on both sides, and move up and down synchronously with the lower bending area of ​​the steel cable chain 1. During the process, the anti-sway baffles 6 on both sides can limit the inner side of the steel cable chain 1, reduce the swaying of the steel cable chain 1 during the movement, and have a good anti-sway effect. This can effectively improve the service life and stability of the steel cable chain 1 and improve the safety and reliability of the high-altitude work equipment.
