Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure hoisting, and particularly relates to a fixing device for a safety rope in steel structure hoisting. Background Technique

[0002] Most of the steel structure hoisting is high-altitude operation. When hoisting a steel beam, a safety rope needs to be set to ensure the operation safety. However, the usual practices are as follows: 1. Set the safety rope on other main structures near the steel beam to be hoisted. However, as the working surface is transferred, it needs to be reset, which is neither safe nor causes a large waste of resources such as labor, materials and machinery; 2. Weld a steel pipe on the steel beam to be hoisted and set the safety rope at the top of the welded steel pipe. This practice may reduce the construction efficiency and even cause irreversible damage to the welded part of the steel beam flange. Therefore, we propose a fixing device for a safety rope in steel structure hoisting to solve the above problems. Content of the Utility Model

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 5 , the present utility model provides a fixing device for a safety rope in steel structure hoisting, including a lifting assembly 1, an A clamping assembly 2 and a B clamping assembly 4 are installed on the lifting assembly 1, and a steel beam 3 is installed on the A clamping assembly 2 and the B clamping assembly 4;

[0024] Among them, the A clamping assembly 2 includes an I-shaped part A 21, an A screw rod 23, an A clamping part 24, a ratchet wheel 25 and a ratchet tooth 26. The I-shaped part A 21 is installed on the lifting assembly 1. An A insertion hole is provided on the I-shaped part A 21. The ratchet wheel 25 is installed on the I-shaped part A 21. The A screw rod 23 is threadedly connected to the ratchet wheel 25, and the A screw rod 23 is arranged in the insertion hole. The A clamping part 24 is installed at the lower end of the A screw rod 23. The ratchet tooth 26 is installed on the I-shaped part A 21, and the ratchet tooth 26 is clamped with the ratchet wheel 25. The upper end of the steel beam 3 is arranged between the I-shaped part A 21 and the A clamping part 24.

[0025] Specifically, when installing the steel beam 3, in order to move it to the designated position, the steel beam 3 needs to be lifted at this time. When lifting, in order to ensure the stability of the steel beam 3 and avoid damaging the steel beam 3, an A-shaped workpiece 21 can be installed on the lifting assembly 1, and a ratchet 25 is installed on the surface of the A-shaped workpiece 21. The A screw rod 23 is slidably arranged in the A insertion hole and is threadedly connected to the ratchet 25. Then, by rotating the ratchet 25, the height of the A screw rod 23 can be changed. Since the A clamping member 24 is installed on the A screw rod 23, the upper end of the steel beam 3 can be arranged between the A clamping member 24 and the lower inner wall of the A-shaped workpiece 21 at this time. By adjusting the height of the A screw rod 23, the upper end of the steel beam 3 can be clamped by the A clamping member 24, so that the steel beam 3 can be stably arranged. And in order to prevent the A screw rod 23 from rising due to the subsequent rotation of the ratchet 25, resulting in the A clamping member 24 being unable to stably clamp the steel beam 3, a ratchet tooth 26 can be arranged on the A-shaped workpiece 21, and the ratchet 25 can be clamped by the ratchet tooth 26 to prevent the ratchet 25 from rotating in the reverse direction.

[0026] In this embodiment, the lifting assembly 1 includes an A-shaped square steel 11 and a B-shaped square steel 12. The A-shaped square steel 11 is installed at the upper end of the A-shaped workpiece 21, and the B-shaped square steel 12 is installed at the lower end of the A-shaped workpiece 21.

[0027] Specifically, during use, in order to enable the A-shaped workpiece 21 to be stably arranged, the A-shaped workpiece 21 is installed at the lower end of the A-shaped square steel 11, and then it can be connected to the upper end of the A-shaped square steel 11 through a safety rope, so that the lifting assembly 1, the A clamping assembly 2 and the steel beam 3 can be lifted.

[0028] In this embodiment, the A clamping assembly 2 further includes a reinforcing rib 22. The reinforcing rib 22 is installed on the A-shaped workpiece 21 and is connected to the surface of the A-shaped square steel 11.

[0029] Specifically, in order to improve the overall strength of the A-shaped workpiece 21, a reinforcing rib 22 can be arranged at the upper end of the A-shaped workpiece 21, and the reinforcing rib 22 is connected to the side end of the A-shaped square steel 11, so that the A-shaped workpiece 21 can be stably connected to the A-shaped square steel 11.

[0030] In this embodiment, the B clamping assembly 4 includes a B-shaped workpiece 41, a B clamping member 42 and a B screw rod 43. The B-shaped workpiece 41 is installed at the end of the B-shaped square steel 12. A limiting groove and a B insertion hole are formed on the B-shaped workpiece 41. The B clamping member 42 is slidably arranged in the limiting groove. The B screw rod 43 is installed at the upper end of the B clamping member 42, and the B screw rod 43 is arranged in the B insertion hole; the lower end of the steel beam 3 is arranged between the B-shaped workpiece 41 and the B clamping member 42.

[0031] Specifically, when clamping the steel beam 3, in order to enable the lower end of the steel beam 3 to be stably installed, a B-shaped workpiece 41 is provided at the lower end of the B-shaped steel 12, and a limiting groove is formed on the surface of the B-shaped workpiece 41. The B clamping member 42 is installed in the limiting groove, the B screw rod 43 is installed on the B clamping member 42, and the B screw rod 43 is slidably arranged in the B insertion hole. At this time, the height of the B screw rod 43 can be adjusted, thereby driving the B clamping member 42 to adjust its height. Then, the lower end of the steel beam 3 can be arranged between the lower inner wall of the B-shaped workpiece 41 and the B clamping member 42, so that the lower end of the steel beam 3 can be clamped by adjusting the height of the B clamping member 42.

[0032] In this embodiment, the B clamping assembly 4 further includes a clamping gear 44, a moving block 45 and a spring 46. The clamping gear 44 is installed on the B-shaped workpiece 41 and is threadedly connected to the B screw rod 43. An installation groove is formed on the B-shaped workpiece 41. The moving block 45 is slidably arranged in the installation groove. The spring 46 is arranged in the installation groove, and the end parts of the spring 46 are respectively connected to the moving block 45 and the inner wall of the installation groove. A clamping block is arranged on the moving block 45, and the clamping block is clamped with the clamping gear 44.

[0033] Specifically, during use, in order to quickly adjust the position of the B screw rod 43, the clamping gear 44 can be threadedly arranged on the B screw rod 43 and rotatably arranged on the B-shaped workpiece 41. Then, by rotating the clamping gear 44, the B screw rod 43 can be driven to adjust its height. In order to prevent the B screw rod 43 from rotating in the reverse direction after the B clamping member 42 clamps the steel beam 3, resulting in unstable clamping, an installation groove can be formed on the B-shaped workpiece 41, and the moving block 45 and the spring 46 are arranged in the installation groove. The moving block 45 and the spring 46 are connected, and the clamping block arranged on the moving block 45 is clamped between the teeth of the clamping gear 44, so that the clamping gear 44 can be limited to prevent the clamping gear 44 from deflecting.

[0034] In this embodiment, the A-shaped steel 11 and the B-shaped steel 12 are similar in size and structure, and the A-shaped workpiece 21 and the B-shaped workpiece 41 are the same in size and shape.

[0035] Specifically, in order to make the B-shaped workpiece 41 have high strength and be not easily damaged, the B-shaped workpiece 41 is adhesively connected to the B-shaped steel 12, and the length of the B-shaped steel 12 can be slightly shorter than that of the A-shaped steel 11. In order to enable the A clamping assembly 2 and the B clamping assembly 4 to have the same clamping position for the steel beam 3, the shapes and sizes of the B-shaped workpiece 41 and the A-shaped workpiece 21 are set to be the same.

[0036] Working principle and usage process of the present utility model: When installing the steel beam 3, at this time, the upper and lower ends of the steel beam 3 can be stably clamped by the A clamping assembly 2 and the B clamping assembly 4. Since the A clamping assembly 2 and the B clamping assembly 4 are stably connected to the lifting assembly 1, at this time, the lifting assembly 1 and the steel beam 3 can be stably connected. Then, by lifting the lifting assembly 1, the steel beam 3 can be stably lifted. By connecting the safety rope to the upper end of the A square steel 11, it is convenient to lift the lifting assembly 1. After lifting the steel beam 3 and moving it to the designated position, the clamping of the A clamping assembly 2 and the B clamping assembly 4 on it can be quickly released, thus facilitating subsequent installation.

[0037] The electronic components and modules used in the content of this utility model can all be parts commonly used in the current market and can achieve the specific functions in this case. Moreover, the specific models and sizes can be selected and adjusted according to actual needs.
