Problems solved by technology

[0004] The jib frame is spliced ​​by the main chord. The main chord mainly includes the chord. The end of the chord is connected with a joint, and the ear hinge is welded on the joint. The splicing of different segments of the chord is realized through the ear hinge. The end of the pipe is welded circularly, so the centering and positioning of the ear hinge and the end of the chord is very important. In the prior art, the ear hinge is directly connected to the end of the chord manually. There will be a small displacement between the lug hinge and the chord, which seriously affects the welding quality and welding efficiency.

Abstract

The invention discloses a centering tool for assembling and welding ear hinges and chord pipes, comprising a base and a sliding table. The sliding table is slidably installed on the base; the slidingtable is provided with a positioning mechanism inserted between a pair of lug plates of an lug hinge; the sliding table is provided with a floating mechanism; the floating mechanism is provided with acentering clamping mechanism inserted into a pair of lug holes of the lug hinge; and a jacking mechanism for supporting the bottom of the ear hinge is arranged on the base. The centering tool has theadvantages of being high in positioning precision, low in labor intensity and capable of improving the welding quality and the welding efficiency.

Description

technical field [0001] The invention mainly relates to the welding technology of the main chord, in particular to a centering tool for butt welding of the ear hinge and the chord assembly. Background technique [0002] Crane is a kind of construction machinery capable of lifting, transporting and loading and unloading materials. It is widely used in construction, transportation, ports, energy and farmland water conservancy and other fields, such as building bridges, installing power generation equipment, shipbuilding, and erecting wind power. generator set etc. [0003] In recent years, with the development of large-scale engineering projects such as petrochemical, nuclear power and steel, the demand for hoisting of super-large equipment is increasing, which puts forward higher requirements for the lifting height and lifting capacity of the crane. The boom is one of the important structural parts of the crane, and the performance of the boom has an important influence on th...
