Description

Technical Field

[0001] The utility model relates to an attachment device for a safety belt for high-altitude operations in a large range, and is particularly applicable to the safety protection of high-altitude operators in large-span steel structures and high-rise frame structures, belonging to the field of civil engineering. Background Art

[0002] Large-span steel structure factory sheds, high-rise frame buildings, etc. are very common in modern construction. High-altitude operations have extremely high requirements for the personal safety of operators. The traditional method mainly involves workers hanging the safety belt on a nearby safety attachment point. There are certain problems: (1) Workers always need to change their working positions. The length of the safety belt is limited, and when changing the working point, it takes a long time to re-fasten the safety belt; (2) There are safety hazards during the process of unfastening and fastening the safety belt each time. The more frequent the number of times, the higher the safety risk. Summary of the Invention

[0003] The utility model provides an attachment device for a safety belt for high-altitude operations in a large range to ensure the personal safety of high-altitude operators and reduce the construction time.

[0004] To solve the above problems, a proposed attachment device for a safety belt for high-altitude operations in a large range includes a positioning device, a positioning steel wire rope, and a movable steel wire rope. Four groups of positioning devices are respectively fixed at the four corner points of the building top surface. Two groups of positioning steel wire ropes are straightened and arranged in parallel, and the four endpoints at both ends of the two groups of positioning steel wire ropes are respectively fixed on the four groups of positioning devices. The two ends of the movable steel wire rope are respectively lapped on the two groups of positioning steel wire ropes through movable snap rings.

[0005] In the aforementioned attachment device for a safety belt, each group of positioning devices includes a top plate, a bottom plate, and a positioning column. Bolt holes are respectively formed at the four corners of the top plate and the bottom plate in a one-to-one correspondence. The top plate and the bottom plate are respectively arranged on the upper and lower sides of the building components on the top floor of the building, and the building components are clamped between the top plate and the bottom plate through high-strength bolts passing through the bolt holes to achieve connection and fixation. The bottom of the positioning column is welded and fixed to the top plate, and the positioning column has a steel wire rope connection part;

[0006] In the aforementioned attachment device for a safety belt, the steel wire rope connection part includes four positioning steel bars respectively fixed on the opposite sides of the positioning column. The four positioning steel bars and the positioning column form a "work" - shaped card slot structure for positioning the fixation of the end of the steel wire rope.

[0007] In the aforementioned attachment device for a safety belt, each group of positioning steel wire ropes is composed of three φ5mm steel wire ropes.

[0008] Compared with the prior art, the utility model has high structural stability, simple processing and can be reused. The operation is simple and convenient, which greatly reduces the time cost of continuously attaching safety belts during the movement of workers at high altitudes and reduces the safety risks during the movement of workers at high altitudes. This structure has been successfully practiced in the construction of multiple buildings, with excellent use effects, significant social and economic benefits, and important guiding significance and promotion value.

[0011] To make the objectives, technical solutions and advantages of the utility model more clear, the following will further elaborate on the utility model in conjunction with the drawings. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0012] Embodiment

[0013] Referring to Figure 1 and Figure 2 , in this embodiment, the safety belt attachment device for large-scale high-altitude operations is improved. The improved safety belt attachment device includes a positioning device 1, a positioning steel wire rope 2 and a movable steel wire rope 3. Four groups of positioning devices 1 are respectively fixed at the four corner points of the building top surface. Two groups of positioning steel wire ropes 2 are straightened and arranged in parallel, and the four endpoints at both ends of the two groups of positioning steel wire ropes 2 are respectively fixed on the four groups of positioning devices 1. Each group of positioning steel wire ropes 2 is composed of three φ5mm steel wire ropes. The two ends of the movable steel wire rope 3 are respectively lapped on the two groups of positioning steel wire ropes 2 through movable snap rings.

[0014] The positioning device 1 includes a top plate 11, a bottom plate 12 and a positioning column 13. Bolt holes 14 are respectively provided at the four corners of the top plate 11 and the bottom plate 12 in a one-to-one correspondence. The top plate 11 and the bottom plate 12 are respectively arranged on the upper and lower sides of the building components on the top floor 4 of the building, and the building components are clamped between the top plate 11 and the bottom plate 12 through high-strength bolts passing through the bolt holes 14 to achieve connection and fixation. The bottom of the positioning column 13 is welded and fixed to the top plate 11. The positioning column 13 has a steel wire rope connection part 15. The steel wire rope connection part 15 includes four positioning steel bars respectively fixed on the opposite sides of the positioning column 13. The "I"-shaped slot structure is formed by the four positioning steel bars and the positioning column 13 to position the fixation of the end of the positioning steel wire rope 2.

[0015] The specific operation key points of this safety belt attachment device are as follows:

[0016] (1) Installation of positioning card slots

[0017] During the construction of the top floor 4 of the building, install the positioning card slots of this device at the four corner points ABCD on the top surface of the building. The positioning card slot consists of a top plate 11, a bottom plate 12, and a positioning column 13: The top plate 11 and the bottom plate 12 are made of Q235 steel plates with a thickness of 1 cm, with holes drilled at the four corners, and clamped to the building components through high-strength bolts to be fixed on the building; the positioning column 13 is made of a φ50mm steel pipe and welded to the top plate 11 through a stiffening plate 16. The height can be freely adjusted according to the on-site construction conditions, and 4 steel bars are welded at the top as positioning steel bars (wire rope connection part 15).

[0018] (2) Installation of wire ropes

[0019] Use a wire rope with a diameter of 5 mm. Fix the wire rope between AB with 3 wire rope clips and install it between the positioning steel bars of the positioning columns 13 at the two corner points A and B. Fix the wire rope between CD with 3 wire rope clips and install it between the positioning steel bars of the positioning columns at the two corner points A and B. The two ends of the wire rope between AC are respectively lapped on the previous two groups of wire ropes with movable snap rings, so that it can move freely.
