DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the utility model, the utility model is further clearly and completely explained below in combination with the reference drawings and in combination with embodiments.

[0018] A typical embodiment of the utility model provides a steel structure roof life line auxiliary installation device, as shown in Figure 1 The steel structure roof life line auxiliary installation device comprises a clamping plate 1, a clamping plate gear 2, an adjusting rack 3, a main support body 4, an arc-shaped support rod 5 and a clamping plate connecting rod 7.

[0019] The main support body 4 is a box body structure and is composed of a top surface, a bottom surface and front and rear side surfaces.

[0020] The front and rear sides of the support body 4 are rotatably mounted with a clamping plate gear shaft 6, and the clamping plate gears 2 are fixedly connected with the clamping plate gear shaft 6. The two clamping plate gears 2 are rotatably mounted inside the main support body 4 in left-right symmetry through the clamping plate gear shaft 6. The adjusting rack 3 is arranged between the two clamping plate gears 2 and is in mesh with the two clamping plate gears 2, and the adjusting rack 3 penetrates through the top and bottom of the support body 4. The clamping plate gear shaft 6 is fixedly connected with one end of a clamping plate connecting rod 7, and the other end of the clamping plate connecting rod 7 is directly or indirectly connected with the clamping plate 1. The arc-shaped support rods 5 are fixedly connected to the rear side of the support body 4, and the lifeline is mounted at the top end of the plurality of arc-shaped support rods 5.

[0021] According to the above embodiment, the clamping plate gears 2 are driven to rotate by moving the adjusting rack 3 up and down, and then the clamping plate connecting rod 7 is driven to rotate, so that the opening width between the two clamping plates 1 changes. The two clamping plates 1 can be clamped on the roof steel beam, and the inner side of the clamping plate 1 is welded or fixed by bolts to the outer side of the steel beam at a determined position. A plurality of lifeline auxiliary installation devices according to the embodiment are arranged at intervals on the edge of the steel structure roof, and the lifeline passes through the front end of the arc-shaped support rod and forms a closed loop.

[0022] In a preferred embodiment, a plurality of positioning holes 8 are arranged at intervals on the adjusting rack 3, and a mounting hole is formed in the front side wall of the support body 4. A positioning pin 9 is inserted into any one of the positioning holes 8 from the mounting hole, and the positioning pin 9 is used to limit the continuous movement of the adjusting rack 3. The positions of the two clamping plates 1 are fixed by using the positioning pin 9.

[0023] In a relatively specific embodiment, a lifeline position ring 10 for the lifeline to pass through is arranged at the top end of the arc-shaped support rod 5, which prevents the lifeline from falling off and ensures a safe area.

[0025] The lifeline position ring and the lifeline position hole described above can be arranged simultaneously or individually. The difference between the lifeline position ring and the lifeline position hole is that the lifeline position hole is a small hole directly formed at the top end of the arc-shaped support rod, while the lifeline position ring is a circular ring fixed at the top end of the arc-shaped support rod. The diameter of the lifeline position ring is larger than that of the lifeline position hole.

[0026] In a relatively specific embodiment, the clamping plate 1 and the clamping plate connecting rod 7 are connected through a clamping plate overpass rod 12. The two ends of the clamping plate overpass rod 12 are connected with the clamping plate 1 and the clamping plate connecting rod 7 respectively through bolts.

[0027] During construction, first, the main support body 4 is determined according to the width of the section steel, the opening width of the clamping plate is determined by moving the adjusting rack, the clamping plate is clamped on the steel beam, then the positioning pin 9 is placed in the positioning hole 8, and the opening size of the clamping plate is further fixed. The inner side of the clamping plate 1 and the inner side of the main support body 4 are fixed on the outer side of the section steel to determine the position, at this time, the arc-shaped supporting rod 5 is placed on the upper part of the roof, the above device is completely installed on the outer side of the section steel, and finally, the lifeline is passed through the lifeline position ring and forms a closed loop.

[0028] The scope of protection of the utility model is not limited to the above specific embodiments, for those skilled in the art, the utility model can have multiple variations and alterations, and any modification, improvement and equivalent replacement made within the concept and principle of the utility model should be included in the protection scope of the utility model.
