Fixture for assembling and welding universal crane arm standard knot

Abstract

The invention discloses a universal crane boom standard knot assembly welding fixture. The universal crane boom standard knot assembly welding fixture can improve the assembly quality, reduce deflection oversize, improve the work efficiency, realize high-efficient interchange and achieve the welding and assembling of boom standard knots of different length, size, and section type on a fixture. The structure thereof comprises a track device; a movable end and a fixed end are installed on the track device; the fixed end comprises a first end plate and a base; the first end plate is arranged on the base; the base is installed on the track device; the movable end comprises a handcart and a second end plate; the handcart is placed on the track device for traveling, and the second end plate is installed on the handcart; meanwhile, the first end plate and the second end plate are equipped with a movably mounted connector positioning device.

Description

technical field [0001] The invention relates to different types of crane jib standard section assembling and welding tooling, in particular to a universal crane jib standard section assembling and welding tool for various truss structures. Background technique [0002] In the current assembly and welding process of the standard section of the crane jib, the main chord and the connecting web system are usually carried out in the form of actual matching and welding. This assembly and welding method has a disadvantage in one aspect: 1. After welding The size error and deformation of each part of the subsequent standard section are large, and the amount of welding deformation is difficult to control. 2. When the rods are deformed or damaged, it is difficult to match and the interchangeability is poor. 3. Jib standard sections of different lengths and different section types need to use different section types of tooling, which greatly wastes raw materials, money and time. This...
