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, and the weight of the chord is very heavy, so the delivery of the chord is very important. If the delivery of the chord is not in place before welding and during the welding process, it will seriously affect the welding quality and welding quality. efficiency

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 and figure 2 As shown, an embodiment of the pipe feeding device used for butt welding of the ear hinge and the chord group of the present invention includes a frame 1, a lifting mechanism 2 and a transfer mechanism 3, and the lifting mechanism 2 is fixed on the frame 1 Above, the transfer mechanism 3 is installed on the frame 1, and the transfer mechanism 3 can move linearly along the frame 1. When assembling, use the hoisting device to hoist the chords to the transfer mechanism 3, and the transfer mechanism 3 linearly moves along the frame 1 to transport the chords to the assembling position, and then the lifting mechanism 2 rises to lift the chords Lift up to the butt weld point. The tube feeding device realizes the linear delivery of the string tube through the transfer mechanism 3, ensuring that the str...

Abstract

The invention discloses a pipe feeding device for ear hinge and chord pipe assembly welding. The pipe feeding device comprises a rack, a lifting mechanism and a transferring mechanism, wherein the lifting mechanism is fixedly arranged on the rack, and the transferring mechanism is arranged on the rack and can linearly move along the rack. The pipe feeding device has the advantages of being simpleand reliable in structure, accurate in conveying and capable of improving the welding quality and the welding efficiency.

Description

technical field [0001] The invention mainly relates to the chord welding technology, in particular to a pipe feeding device 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 the lifti...
