Description

Balance lifting appliance for welding H-shaped steel

Technical Field

The invention relates to the technical field of steel structure processing, in particular to a balance lifting appliance for welding H-shaped steel.

Background

In practical engineering application, the welded H-shaped steel section can be processed, designed and combined at will along with engineering, and can be manufactured into special specifications to match the practical requirements of special engineering; through the economical design, the section moment, the section coefficient, the compression resistance and the bearing load are optimized and improved. Based on the flexibility of welding H-shaped steel and other excellent holes, the welding method is widely applied to structures such as beams, columns and the like of a building steel structure.

In practice, however, H-shaped steel with narrow flange plates, 100mm/150mm in width and 40mm in web thickness is frequently encountered; this dimension results in the flap having a single edge projecting width dimension that is too narrow, only 30mm/55 mm. If the 10mm leg size is subtracted, the edge clearance is only 25mm, 45 mm. In the actual manufacturing process, due to the narrow flange plate, the H-shaped steel with the structure is very difficult to hoist and turn in the processes of assembling, submerged arc welding, riveting, cleaning, shipping and the like; due to the fact that the clamping size is small, clamping force is not enough, safety is extremely low when the lifting clamp is used, and finally the traditional lifting clamp cannot be used. Even if the chain and the steel wire rope are used for binding, hoisting and overturning, the operation efficiency is extremely low. Therefore, how to solve the problem of safe and efficient lifting in the manufacturing process is critical.
