Abstract
Description
Technical Field
[0001] The utility model relates to the field of high-altitude operation safety protection in the machinery manufacturing industry, in particular to a novel safety suspension rod. Background Art
[0002] In the manufacturing process of some large-scale mechanical equipment, due to the high height of the mechanical equipment, workers usually need to perform high-altitude operations during welding or equipment assembly. According to the safety protection regulations for high-altitude operations, personnel need to use corresponding safety ropes to ensure their lives when performing high-altitude operations. Usually, a tensioned steel wire rope is fixed on the installation boom, and the personnel use a buckle to hang the safety rope on the steel wire rope during high-altitude operations. Since the existing safety boom is a vertically set rod, it does not have a climbing structure itself, and other climbing equipment is required for assistance when in use, and the steel wire rope is only tightly fixed at its top, which cannot effectively ensure its safety. For this reason, we designed a new type of safety boom. Utility Model Content
[0003] In order to solve the technical problem that other climbing equipment is needed for assistance during use, the utility model provides a novel safety lifting rod.
[0004] The utility model is implemented by the following technical scheme: a novel safety boom, comprising two symmetrically arranged counterweight bases, each of which is fixed with a climbing column designed to be vertically upward, the climbing column comprising four supporting columns distributed in a rectangular structure, a plurality of equally spaced reinforcing frames welded from bottom to top between the four supporting columns, and the reinforcing frame comprising four square steels, a plurality of equally spaced climbing frames welded from bottom to top between the four supporting columns, and the climbing frame comprising three connecting rods, and the three connecting rods are distributed in a U-shaped structure;
[0005] A self-locking hand winch is fixed above the left counterweight base, a wire rope is arranged on the wire wheel of the self-locking hand winch, and the other end of the wire rope passes through the reinforcement frames of two climbing columns and is connected above the right counterweight base.
[0006] As a further improvement of the above scheme, a fixed hanging ring is fixed above the counterweight base on the right side, and a hook is provided at the end of the wire rope away from the self-locking hand winch. The hook is hung on the fixed hanging ring, and one end of the wire rope is overlapped on the square steel of the reinforcement frame, and the wire rope is hung on the fixed hanging ring through the hook. Thereafter, the self-locking hand winch is rotated to make the wire rope in a tensioned state, so that the height of the wire rope can be adjusted as needed to make it at a suitable working height.
[0007] As a further improvement of the above solution, the edges of the four square steels of the reinforcement frame are chamfered to form an arc surface, and a portion of the inner square steel is cut away to form an arc groove, and the wire rope can be placed in the arc groove. When the wire rope is hung on the fixed hanging ring, the wire rope can also be wrapped around the square steel several times, thereby ensuring the firmness of the connection.
[0008] As a further improvement of the above solution, there is a spacing of 2m between two adjacent reinforcement frames, and a standing frame is slidably arranged above the multiple reinforcement frames, wherein the standing frame includes a rectangular frame, and a wire mesh is laid above the rectangular frame. Workers can stand on the standing frame when performing their work, which provides a place for the workers to stand and also enables the workers to not have to climb on the climbing frame all the time, thereby improving safety.
[0009] As a further improvement of the above solution, a guide column is provided above the steel on the outward side of the reinforcement frame, and a limited sliding groove is provided on the inward side surface of the guide column;
[0010] A guide slider is arranged on the rear side of the outward surface of the rectangular frame, and the guide slider slides forward and backward in the guide slot, so that the whole standing frame can move forward and backward without completely separating from the climbing column, thereby facilitating people to stand on the standing frame.
[0011] As a further improvement of the above solution, the front and rear side surfaces of the standing frame are flush with the front and rear outer surfaces of the two square steels in the reinforcement frame, and the distance between the inward side of the standing frame and the inner square steel is 5-10 cm, so there will be no collision with the wire rope.
[0012] Compared with the prior art, the beneficial effects of the present invention are:
[0013] 1. The utility model provides a plurality of climbing frames on the climbing column, and the climbing frames are in a U-shaped structure. The structure has a climbing function and also forms a protective frame structure, which is similar to a safety cage, thereby ensuring the safety of personnel when climbing. No additional climbing auxiliary equipment is required during the climbing operation. The adjustable steel wire rope is provided to make the climbing operation safer.
[0014] 2. A standing frame is set up on the climbing column by sliding it back and forth, so that people have a standing point during the climbing process, and the height between each two adjacent standing frames is low, so that even if people step on empty feet, there is support and protection below, which improves safety.

[0021] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.
[0022] Embodiment:
[0023] Please combine Figure 1-Figure 4 In this embodiment, a new type of safety boom includes two symmetrically arranged counterweight bases 1. Vertically upwardly designed climbing columns 2 are fixed above both of the two counterweight bases 1. The climbing column 2 includes four support columns 21 distributed in a rectangular structure. A plurality of equally spaced reinforcement frames 22 are welded between the four support columns 21 from bottom to top, and the reinforcement frame 22 is composed of four square steels. A plurality of equally spaced climbing frames 23 are welded between the four support columns 21 from bottom to top, and the climbing frame 23 includes three connecting rods, and the three connecting rods are distributed in a U-shaped structure;
[0024] A self-locking hand winch 5 is fixed above the left counterweight base 1. A steel wire rope 4 is arranged on the wire wheel of the self-locking hand winch 5. The other end of the steel wire rope 4 passes through the reinforcement frame 22 of the two climbing columns 2 and is connected above the right counterweight base 1.
[0025] A fixed hanging ring 6 is fixed above the right counterweight base 1. A hook 41 is arranged at one end of the steel wire rope 4 away from the self-locking hand winch 5. The hook 41 is hung on the fixed hanging ring 6. One end of the steel wire rope 4 is lapped on the square steel of the reinforcement frame 22, and the steel wire rope 4 is hung on the fixed hanging ring 6 through the hook 41. Then, by rotating the self-locking hand winch 5, the steel wire rope 4 can be in a tensioned state, so that the height of the steel wire rope 4 can be adjusted according to needs to make it at a suitable working height.
[0026] The edges of the four square steels of the reinforcement frame 22 are all chamfered to form an arc surface, and a portion of the inner square steel is cut away to form an arc groove, and the wire rope 4 can be placed in the arc groove. When the wire rope 4 is hung on the fixed hanging ring 6, the wire rope 4 can also be wrapped around the square steel for several turns, thereby ensuring the firmness of the connection.
[0027] There is a spacing of 2m between two adjacent reinforcement frames 22, and a standing frame 3 is slidably arranged on top of multiple reinforcement frames 22, wherein the standing frame 3 includes a rectangular frame 31, and a wire mesh 32 is laid on top of the rectangular frame 31. Support rods are also arranged on the left and right sides of the inside of the reinforcement frame 22, and the two support rods are respectively located on the left and right sides below the rectangular frame and they are in sliding contact. The support rods can support the left and right sides of the rectangular frame 31 of the standing frame 3 below. At the same time, the spacing between the two support rods is large, and it will not cause obstacles to climbing. Workers can stand on the standing frame 3 when performing operations, which provides a place for workers to stand and also enables workers to not have to climb on the climbing frame 23 all the time, thereby improving safety.
[0028] A guide column 7 is arranged above the steel on the outward side of the reinforcement frame 22, and a limited position slide groove is arranged on the inward side surface of the guide column 7;
[0029] A guide slider is provided on the rear side of the outward surface of the rectangular frame 31 , and the guide slider slides forward and backward in the guide slot. The entire standing frame 3 can move forward and backward without completely separating from the climbing column 2 , making it convenient for people to stand on the standing frame 3 .
[0030] The front and rear surfaces of the standing frame 3 are flush with the front and rear outer surfaces of the two square steels in the reinforcing frame 22, and there is a 5-10 cm gap between the inner side of the standing frame 3 and the inner square steel, so there will be no collision with the wire rope 4.
[0031] The implementation principle of a new type of safety boom in the embodiment of the present application is as follows: in actual use, a forklift or an aerial vehicle can be used to place the two safety booms in a suitable position, and the wire rope 4 is passed through one end of the wire rope 4 and overlapped on the square steel of the reinforcement frame 22, and the wire rope 4 is hung on the fixed hanging ring 6 through the hook 41. Then, the self-locking hand winch 5 is turned to make the wire rope 4 in a tensioned state. Before the wire rope 4 is hung on the fixed hanging ring 6, the wire rope 4 can also be wound around the square steel for several turns, thereby ensuring the firmness of the connection. After that, when the worker is working at height, he can climb up along the climbing frame 23 (after being above the standing frame 3, he can reset the standing frame 3 with his feet). When encountering the standing frame 3, he only needs to move the standing frame 3 forward to continue climbing up. When climbing to the required height, the worker can use his feet to move the standing frame 3 backward to reset it. At this time, he can stand on the standing frame 3, and then he can connect the installation rope buckle to the wire rope 4, and then he can carry out aerial work;
[0032] By arranging a plurality of climbing frames 23 on the climbing column 2, and the climbing frames 23 are in a U-shaped structure, the structure has a climbing function, and also forms a protective frame structure, which is similar to a safety cage, thereby ensuring the safety of personnel when climbing. No additional climbing auxiliary equipment is required during the climbing operation, and the adjustable steel wire rope 4 is provided, so that the climbing operation is safer;
[0033] By sliding a standing frame 3 forward and backward on the climbing column 2, personnel have a standing point during the climbing process, and the height between every two adjacent standing frames 3 is relatively low, so that even if a person misses a step, there is support and protection below, thereby improving safety.
[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
