Tailor Welding Method of Hydraulic Support Shelter Beam

Abstract

The invention discloses a welding method of a hydraulic bracket shield beam. The welding method comprises welding of a left box-shaped main rib, a right box-shaped main rib, a top plate, a balance lug base and a cover plate: (1) welding of the left box-shaped main rib and the right box-shaped main rib: inner main rib plates, outer main rib plates, inner hinge lug plates and outer hinge lug plates of the left and right box-shaped main ribs are put in appointed positions of an assembly platform; and internal rib plates are assembled between the inner and outer main rib plates of the left and right box-shaped main ribs for positioned welding for reinforcement; (2) welding of the top plate and the balance lug the top plate is put in an appointed position of the assembly platform; and a middle rib plate module and the balance lug base are assembled in the middle position of the surface of the top plate for positioned welding and reinforcement; (3) the left box-shaped main rib and the right box-shaped main rib are assembled together; and (4) the shield beam is overally welded. The welding method of the hydraulic bracket shield beam has the advantages of simple welding process, high operability, large reduction of the welding difficulty under the precondition of guaranteeing the assembly precision, and improvement of the welding efficiency.

Description

technical field [0001] The invention relates to a hydraulic support shield beam, in particular to a tailor welding method for a hydraulic support shield beam. Background technique [0002] As the main support equipment in coal mine fully mechanized mining equipment, hydraulic support has the characteristics of large volume and weight, harsh service conditions, and many box-type welded structures. The cover beam is the main structural part of the hydraulic support, which is composed of box-shaped main rib components, top plate, internal rib plate, ear plate, cover plate and other parts. At present, the tailor welding method in the manufacturing process of the cover beam is to first draw the position lines of the four main ribs on the top plate, and then use the mandrel to assemble four sets of main rib components (for welds that are difficult to weld after assembly, pre-buried Welding), then use the inspection mandrel to inspect the coaxiality of the hinge holes of the four ...

AI Technical Summary

Problems solved by technology

[0003] With the advancement of technology, the automatic operation method of welding robot is gradually being applied to the tailor welding of hydraulic support structural parts, while the traditional tailor welding method is obviously difficult to meet the production requirements of tailor welding robot

Especially in the way of directly assembling the four sets of main rib components on the top plate, due to the limitation of the robot welding torch, most of the welds on the four sets of main rib components after assembly will be difficult to weld, and if the four sets of main rib components are assembled before assembly The welds are all welded well, and a large amount of welding will lead to serious deformation of the main ribs, which will cause great difficulties in the subsequent assembly of internal ribs, cover plates and other components
