Problems solved by technology

[0002] The standard section of the tower crane is generally a quadrilateral truss structure, and its single section length is generally more than 2.5 meters. In this way, the welding tooling equipment occupies a large area, and workers need to climb up and down for welding to improve the welding accuracy, otherwise it will affect the welding accuracy of the standard joint, and because of the large amount of welding, a large number of welding will be generated during the welding process Smoke and dust, the pollution is relatively serious, and will endanger the health of workers

Abstract

The invention discloses a tower crane standard joint welding device and a method. The tower crane standard joint welding device and the method solve the problems that a standard joint welding tool in the prior art is large in floor area, and smog generated due to welding harms the human body health, and have the beneficial effects that dust can be effectively removed and the welding precision and quality are improved. According to the scheme of the tower crane standard joint welding device, the tower crane standard joint welding device comprises a bottom frame, a positioning mold and a smoke collecting hood, wherein the bottom frame supports a rotating mechanism; the positioning mold is used for positioning a main limb of a to-be-welded standard joint, and the rotating mechanism is in contact with the positioning mold so that the positioning mold can be driven to rotate due to rotation of the rotating mechanism; the smoke collecting hood is used for collecting soot generated due to welding from the position above the positioning mold and / or the side portion; the smoke collecting hood communicates with a pipeline; an outer pipeline is inserted into one side of the pipeline to be arranged; a lifting mechanism is arranged between the pipeline and the outer pipeline, and the outer pipeline is connected with a slewing mechanism; and through the slewing mechanism and the lifting mechanism, the pipeline is driven to lift and rotate, so that the standard joint where welding is completed is elevated from the positioning mold.

Description

technical field [0001] The invention relates to the field of tower cranes, in particular to a welding device and method for a standard section of a tower crane. Background technique [0002] The standard section of the tower crane is generally a quadrilateral truss structure, and its single section length is generally more than 2.5 meters. In this way, the welding tooling equipment occupies a large area, and workers need to climb up and down for welding to improve the welding accuracy, otherwise it will affect the welding accuracy of the standard joint, and because of the large amount of welding, a large number of welding will be generated during the welding process Smoke and dust, pollution is relatively serious, and will endanger the health of workers. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a welding device for a standard section of a tower crane. The overall equipment occupies a relative...
