Description

Technical Field

[0001] The utility model relates to the field of steel structure installation, in particular to a steel structure auxiliary bolt tightening device. Background Art

[0002] In large-scale steel structure projects, bolt connection becomes a key means to ensure structural stability and safety due to the large size and complex structure of the components. However, in the actual installation process, facing these huge steel structure components, the bolt tightening operation often faces many challenges.

[0003] Specifically, after the bolt passes through the mounting hole of the steel structure component, since the tail of the bolt has not been fixed at this time, during the subsequent tightening process, the bolt itself is likely to rotate along with the rotational force applied by the tightening tool. This "follow-up" phenomenon not only makes the tightening operation difficult, but also may cause the bolt to fail to be properly tightened to the predetermined torque, thereby affecting the connection strength and stability of the entire structure.

[0004] Therefore, it is necessary to provide a new steel structure auxiliary bolt tightening equipment to solve the above technical problems. Utility Model Content

[0028] The working principle of the steel structure auxiliary bolt tightening device provided by the utility model is as follows:

[0029] First, the key component of the equipment, the "-shaped connection seat 4, is accurately placed at the connection between the steel beam 3 and the connection piece 2, and is fixed with bolts to ensure a firm connection with the steel structure; this step provides a solid foundation for subsequent bolt tightening operations;

[0030] Next, a tool such as an inner hexagonal wrench is inserted into the inner hexagonal groove 13 at one end of the threaded rod 6 and rotated; as the threaded rod 6 rotates, the threads on it are tightly matched with the threads 9 in the connecting groove 8 inside the U-shaped connecting seat 4, generating an axial moving force; this force drives the threaded rod 6 to drive the clamping block 5 to move axially along the guide structure of the U-shaped connecting seat 4 until the rubber block in the clamping block 5 is tightly fitted to the steel beam 3;

[0031] At the same time, the rotation of the threaded rod 6 also compresses the return spring 10 located in the connecting groove 8 through the interaction between the pad 12 and the piston 11; this compression process not only provides the necessary buffer and guidance for the rotation of the threaded rod 6, but more importantly, it leads to an increase in the air pressure in the hollow part of the connecting groove 8 and the "-shaped connecting seat 4; as the air pressure increases, the airbag 7 installed on one side of the "-shaped connecting seat 4 gradually expands, and its elastic and wear-resistant material and anti-slip texture on the surface ensure close contact and firm fixation with the bolt head, effectively preventing the bolt from rotating during the tightening process;

[0032] Finally, with the auxiliary fixation of the airbag 7, the operator can easily apply torque to the bolt through the tightening tool to complete the tightening operation; during the whole process, the L-shaped connecting seat 4, threaded rod 6, clamping block 5 and airbag 7 and other components work together to achieve fast and stable tightening of the bolt, greatly improving work efficiency and tightening quality.
