Description

Technical Field

[0001] The invention belongs to the field of web welding and relates to a mechanical clamp technology, in particular to a crane web angle steel reinforcement assembly clamp. Background Art

[0002] The web of a crane is an important component of the crane's main beam. The web can withstand various loads when the crane is working, including the weight of the hoisted objects, the weight of the crane itself, and the dynamic loads during operation. The web also helps to maintain the stability and rigidity of the crane's main beam, preventing the main beam from deforming or twisting when subjected to force. The web can transfer the load from one part of the crane to another, ensuring that the entire crane structure is evenly stressed.

[0003] The main purpose of welding angle steel on the web is to enhance the strength and stability of the web. As a reinforcement material, angle steel can provide additional support and rigidity, especially in areas where the web needs to bear large loads or stress concentration. Welding angle steel can effectively improve the load-bearing capacity of the web and prevent the web from deforming or breaking under high stress. In addition, the welding of angle steel can also improve the force distribution of the web and reduce local stress concentration, thereby extending the service life of the web.

[0004] In the belly welding of cranes, welding is usually carried out with a simple welding fixture. During the welding process, a downward pressure is applied to the angle steel so that the angle steel is close to the belly plate to complete spot welding. However, the fixture is inconvenient to move and has no precision. Welding is often completed based on the workers' experience. This fixture cannot meet the requirements of fast welding and precision, and this welding fixture usually requires multiple workers, resulting in a waste of manpower.
