Assembly welding tool of installation bases and connecting method of lifting mechanism and balance arm

Abstract

An assembly welding tool of installation bases is used for welding the installation bases onto a balance arm of a tower crane in an assembled mode, and the installation bases welded in the assembled mode and a plurality of connection bases arranged on a lifting mechanism of the tower crane can be arranged together respectively and correspondingly. The assembly welding tool comprises a frame and a plurality of assembly welding plates arranged on the frame, the positions of the assembly welding plates correspond to the positions of the installation bases, needing to be welded in the assembled mode, on the balance arm, and each assembly welding plate is provided with at least one positioning hole. When the installation bases are welded to the balance arm in the assembled mode, the installation bases can be detachably arranged on the assembly welding plates respectively, and the assembly welding tool enables the installation bases to be positioned on the balance arm. When the positions of connecting holes are determined in the connection bases, the assembly welding tool is placed on the lifting mechanism, the assembly welding plates correspond to the connection bases respectively, and according to the position of the positioning hole in each assembly welding plate, the position of the connecting hole in the corresponding connection base is determined. The invention further provides a connecting method of the lifting mechanism and the balance arm.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a welding fitting for fitting and welding a mounting seat and a connection method for realizing the connection between a lifting mechanism and a balance arm by using the fitting and welding fitting. Background technique [0002] In recent years, with the in-depth development of the construction industry, super-large tower cranes (also referred to as "tower cranes") have been widely used. The tower crane includes a hoisting mechanism and a balance arm, the balance arm includes a forearm section, the hoisting mechanism is installed on the forearm section, and the hoisting mechanism is, for example, a winch. [0003] figure 1 with figure 2 Shown is the hoisting mechanism 1 of the tower crane, only the base portion of the hoisting mechanism 1 is shown in the figure, the bottom of the hoisting mechanism 1 includes four connecting seats 11, and the four connecting seat...

Problems solved by technology

[0008] In the above-mentioned matching welding method for the mounting seat 21, when the production cycle of the balance arm 2 and the lifting mechanism 1 is different, it is necessary to wait for synchronization, and the lifting mechanism 1 must be transferred to the production line of the balance arm 2, and the production efficiency is low; The versatility is poor, and the process of matching and welding numbers is added; the lifting mechanism 1 and the balance arm 2 are relatively heavy, and the work intensity is high; safety hazards in
