Universal adjustable pipe female welding bracket

Abstract

The invention belongs to the field of tubular bus welding process attachment devices, and particularly relates to a universal adjustable tubular bus welding bracket. The universal adjustable tubular bus welding bracket comprises an axial supporting base. A plurality of axial guide wheels are distributed on the axial supporting base. Tubular buses are erected on the axial guide wheels, and the outer rims of all the axial guide wheels are matched to form a supporting part. The universal adjustable tubular bus welding bracket further comprises a lifting mechanism. A rotation supporting base is arranged on the lifting mechanism. The roll surfaces of a plurality of circumferential wheels on the rotation supporting base form a contact face. The minimum height of the contact face is lower than the supporting height of the tubular buses on the supporting part of the axial supporting base after the lifting mechanism falls. The maximum height of the contact face is higher than the supporting height of the tubular buses on the supporting part of the axial supporting base after the lifting mechanism rises. The universal adjustable tubular bus welding bracket achieves the online rotation and frontward-backward axial movement capacity in the tubular bus welding process, and therefore the aim of the one-time online welding is achieved under the condition that no mechanical hoisting is needed, the welding speed can be obviously increased, and the welding quality can be obviously improved.

Description

technical field [0001] The invention belongs to the field of auxiliary equipment for welding process of tubular busbars, and in particular relates to a general-purpose adjustable tubular welding bracket capable of one-time on-line welding of tubular busbars without mechanical lifting assistance. Background technique [0002] With the rapid development of my country's economy, the demand for electricity in the whole society is increasing day by day. At present, the low-voltage side of 110kV and 220KV substations adopts 10kV and 35kV voltage levels. With the increase of the main transformer capacity, the rated current of the incoming line side of the low-voltage side of the transformer is also increasing. It is increasingly difficult for conventional rectangular bus bars to meet the requirements of bus heating and short-circuit electromotive force technically and structurally. As a substitute for rectangular busbars, tubular busbars (referred to as tubular busbars) are mainly...

Problems solved by technology

The disadvantage of the above traditional structure is that due to the huge weight of the tube nut itself, how to completely realize the surrounding welding of the end of the tube nut is very important on the tube nut support frame that can only be guided along the tube parent axial direction

However, the actual situation is just the opposite. Since the pipe nut cannot rotate during the above welding process, the pipe nut can only be lifted by a crane after welding for one section, then rotated, and then put down the pipe nut again to continue welding the next section. obviously unavoidable

Even if the human factor is eliminated as much as possible in welding, it can only weld up to 80% of the entire welding workload in a single welding

In addition, due to the need to lift and rotate the pipe nut after welding one section to weld the next section, regardless of whether there is a welding concentricity deviation after the two-section pipe nut connected by only a small end is lifted at the same time, rotated and repositioned And the ensuing welding quality problems; under its own huge self-weight, the lifting operation also needs to wait for the welded tubular busbar to be completely cooled before it can be performed, which greatly increases the welding time, and it is bound to be extremely difficult. Greatly increased the actual construction period, and finally caused great troubles for the construction unit
