[0006] In order to achieve the above-mentioned purpose, the utility model adopts the technical scheme: a lifting clamp without damaging H-shaped steel cross structures, comprising two shape plates, a round hole and an oblong hole are formed on the shape plates, the positions of the round hole and the oblong hole correspond to the bolt holes on the web of the H-shaped steel cross structure, a lifting round hole is arranged above the shape plates, the shape plates are installed on the web through a bolt and nut structure, and the two shape plates are spliced by passing a lifting hook through the lifting round hole.

[0007] Through the above technical scheme, the bolt and nut structure can shorten the distance between the two shape plates, the shape plates can be closely attached to the web during use, the weight of the web is not borne by the bolts, the design of the oblong hole can bypass the damaged bolt holes, and the bolts can be fixed in the complete bolt holes.

[0008] The lifting clamp without damaging H-shaped steel cross structures of the utility model is further provided as follows: the lifting hook comprises a U-shaped connecting rod and a cylinder, the cylinder is matched with the lifting round hole, and the cylinder penetrates through the U-shaped connecting rod.

[0009] Through the above technical scheme, the shape plates can slide on the cylinder, the shape plates can be closely attached to the web, and the U-shaped connecting rod can pass through the lifting rope.

[0010] The lifting clamp which does not damage the H-shaped steel cross structure is further provided with: the diameter of the cylinder is greater than the diameter of the bolt hole.

[0011] By adopting the above technical scheme, it is ensured that the force that can be borne by the cylinder is greater than the force that can be borne by the bolt nut.

[0012] The lifting clamp which does not damage the H-shaped steel cross structure is further provided with: the length of the oblong hole is greater than the length of the straight line which connects the positions of the three bolt holes on the same straight line on the web plate.

[0013] By adopting the above technical scheme, the undamaged bolt hole can be selected in the oblong hole.

[0014] The lifting clamp which does not damage the H-shaped steel cross structure is further provided with: the lifting hole is located on the median line of the circular hole and the oblong hole.

[0015] By adopting the above technical scheme, the stability of positioning is ensured.

[0016] Compared with the prior art, the lifting clamp which does not damage the H-shaped steel cross structure has the following beneficial effects:

[0017] 1. The bolt nut structure of the lifting clamp which does not damage the H-shaped steel cross structure can shorten the distance between the two shape plates, and in use, the shape plates can be close to the web plate, so that the bolt can avoid bearing all the weight of the web plate.

[0018] 2. The design of the oblong hole of the lifting clamp which does not damage the H-shaped steel cross structure can bypass the damaged bolt hole, so that the bolt can be fixed in the complete bolt hole. BRIEF DESCRIPTION OF DRAWINGS
