Problems solved by technology

[0003] However, the positioning welding of the above-mentioned crane extension jib body assembly is cumbersome and the welding efficiency is low, and the overturning operation of the jib during the welding process can easily cause deformation of the jib and welding, which directly affects the entire augmentation. The overall performance of the jib frame

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the drawings.

[0034] In the present invention, in order to provide a novel process method for the assembling and positioning welding of the extended boom frame body, firstly, a head and tail type rotatable positioner tooling with a lifting platform is provided. Such as Figure 5 As shown, the head and tail type rotatable positioner tooling with a lifting platform includes a lifting platform 51, a head rotatable positioner 52 and a tail rotatable positioner 53, wherein the head rotatable positioner 52 and the tail The rotatable positioner 53 may have the same structure or a different structure. The head rotatable positioner 52 includes a porous tooling bottom plate 521 and a supporting device 522; the tail rotatable positioner 53 includes a porous tooling bottom plate 531 and a supporting device 532. It can be seen from the figure that the head rotatable positioner 52 and the tail rotatab...

Abstract

The invention provides a head and tail-type rotatable positioner tool with a lifting platform, and a process method for section-increased cantilever crane body assembly positioning welding adopting the tool. In the method, the lifting platform and the head and tail-type rotatable positioner are adopted; the assembly positioning welding of an overall section-increased cantilever crane body is finished in limited ground space, which saves fussy operations of welding piece by piece and assembling finally in conventional welding; simultaneously, the welding of all ventral tubes is performed on a horizontal plane, which saves a trouble in lineation vertical assembly in the conventional welding; moreover, the welding process of the overall positioning welding is finished under the restriction of a tool, which effectively avoids cantilever crane distortion and welding distortion caused by overturning; and therefore, the welding quality and the welding efficiency of the section-increased cantilever crane body are improved fundamentally.

Description

Technical field [0001] The invention relates to a welding device and a process method for positioning welding, in particular, to a welding device and a process method for assembling positioning welding of an extended arm frame body. Background technique [0002] In the prior art, the welding process for assembling the positioning welding of the crane's extended boom body usually adopts the steps of first welding each component separately, and then assembling and welding forming, such as Figure 1-Figure 4 Shown. Specifically, in figure 1 , First place the two main chords 1 on the processing platform 2; figure 2 In the middle, the abdominal tube 3 is assembled between the two main chord tubes 1, and tack welding is performed to form an important part of the boom body "piece"; then, as image 3 In, will figure 2 The two sets of "sheets" welded in the middle are fixed in two layers on the square tooling 4, and the web tube 5 is installed between the two sets of "sheets" along t...
