Synchronously-ejecting welding mechanism for lower welding of steel bar trusses

Abstract

The invention relates to a synchronously-ejecting welding mechanism for the lower welding of the steel bar trusses, which is particularly used for synchronously welding the steel bar trusses and belongs to the technical field of the steel bar trusses. The synchronously-ejecting welding mechanism for the lower welding of the steel bar trusses comprises a synchronous connecting rod, wherein two ends of the synchronous connecting rod are connected with a first synchronous gear and a second synchronous gear respectively; a first speed reducer and a third speed reducer are symmetrically arranged on a first frame; the first speed reducer and the third speed reducer are connected by a first transmission connecting rod; two ends of the first transmission connecting rod are connected with the first frame through a first transmission connecting rod seat; the middle part of the first transmission connecting rod is provided with a first bevel gear; the first bevel gear is connected with the first synchronous gear in an engagement way. The welding mechanism provided by the invention is adjustable so as to be capable of meeting various specifications, as well as be available for simultaneous adjustment and synchronous lifting.

Description

technical field [0001] The invention relates to a synchronous welding mechanism for welding and ejecting a steel bar truss, in particular to the synchronous welding of a steel bar truss, and belongs to the technical field of a steel bar truss. Background technique [0002] The reinforced truss mainly consists of one upper string bar (straight bar), two lower string bars (straight bar), and two web bars (wave-shaped). The upper string bar and the web bar bar, and the lower string bar and the web bar bar are integrated by resistance welding. The lower welding process is realized by the welding of the lower welding mechanism. In the prior art, the lower welding mechanism cannot be raised or lowered during the welding process, or cannot be raised and lowered at the same time, and cannot handle welding requirements of different specifications. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above deficiencies, so as to provide a synchr...
