Problems solved by technology

When the sling with this structure bears different loads on the left and right pull rod components, the welding machine will not be level, but the level cannot be adjusted, which will bring great inconvenience to the operation of the welding machine during the welding process.
The Chinese patent No. 201020184223.5 discloses a spreader with an adjustable center of mass. It forms a lifting lug adjustment mechanism through connecting rods, nuts, adjusting handles and other parts. Although it can adjust the position of the lifting lug, it has complex structure and adjustment The disadvantages of cumbersome operation and prone to jamming
In addition, the existing spreader does not have the insulation function and cannot be used on the hanging welding machine

Abstract

The invention discloses a leveling lifting appliance for a suspension type welding machine. The leveling lifting appliance comprises a lifting lug and two draw bar assemblies and further comprises a screw, a beam and a U-shaped bolt, a connection sleeve is arranged on the lower portion of the lifting lug, the connection sleeve is sleeved on the screw, two adjusting screw nuts are in threaded connection with the screw, the two adjusting screw nuts respectively abut against the two ends of the connection sleeve, one draw bar assembly is respectively hinged with the two ends of the screw, each draw bar assembly comprises a jaw bolt, a first nut, a sleeve, a plug, an insulation sleeve and a draw bar, the lower portion of the draw bar is fixedly connected with the beam, and the end portion of the U-shaped bolt penetrates through a jack on the beam to be installed and connected onto the beam through a second nut. The leveling lifting appliance is simple in structure, simple and convenient to adjust and operate and applicable to the suspension type welding machine and has an insulation function.

Description

technical field [0001] The invention relates to a rail welding device, in particular to a hanger for a hanging welding machine. Background technique [0002] At present, the hanger of the suspension welding machine is mainly composed of lifting lugs and two pull rod assemblies connected on the lifting lugs. When the sling with this structure bears different loads on the left and right pull rod assemblies, the welding machine will not be level, but the level cannot be adjusted, which will bring great inconvenience to the operation of the welding machine in the welding process. The Chinese patent No. 201020184223.5 discloses a spreader with an adjustable center of mass. It forms a lifting lug adjustment mechanism through connecting rods, nuts, adjusting handles and other parts. Although it can adjust the position of the lifting lug, it has complex structure and adjustment The disadvantages of cumbersome operation and prone to jamming phenomenon. In addition, the existing spr...
