Description

Technical Field

[0001] The utility model relates to the technical field of welding devices for lifting accessories, in particular to a welding device for lifting accessories for cranes. Background Art

[0002] Crane refers to a multi-action lifting machinery that can lift and carry heavy objects vertically and horizontally within a certain range. It is also called a crane, a gantry crane, a crane, and a tire crane. The main features of the crane are: its driving cab and the lifting control room are combined into one, and it is evolved from a crawler crane (crawler crane). The crawler and the traveling bracket of the walking mechanism are transformed into a chassis with tires, which overcomes the disadvantage of the crawler plate of the crawler crane (crawler crane) causing damage to the road surface. It belongs to material handling machinery. Some lifting equipment has the working characteristics of intermittent movement, that is, the corresponding mechanisms of the actions of picking up materials, moving, unloading, etc. work alternately in a working cycle. The development and use of cranes in the market are becoming more and more extensive. Due to the frequent accidents of lifting and traveling with weights without outriggers, the driving speed is also faster than that of crawler cranes; the operation is stable, the lifting weight is large, and it can travel with weights within a specific range, but it must ensure that the road is flat and solid, the tire pressure meets the requirements, and the lifting distance from the ground shall not exceed 50CM; it is forbidden to travel long distances with loads. In order to ensure the safety of the operation, it is basically forbidden to carry out lifting operations without outriggers in China. The types of steel wire ropes used in cranes include phosphate coated steel wire ropes, galvanized steel wire ropes and smooth steel wire ropes. Lifting accessories are key components in cranes. Since lifting accessories need to withstand huge tensile forces, they cannot be assembled using other connection methods. Welding is required to ensure the firmness of lifting accessories.
