Hydraulic support top beam tailor-welding tool

Abstract

The invention belongs to the technical field of hydraulic support welding, and particularly relates to a hydraulic support top beam tailor-welding tool. The hydraulic support top beam tailor-welding tool comprises a rectangular welding platform, a locking and positioning device which is located on the front portion of the rectangular welding platform and used for fixing rib plates arranged on thehead of a hydraulic support top beam and a shaft positioning device which is located on the back portion of the rectangular welding platform and used for fixing the tails of hydraulic support top beamparts; the hydraulic support top beam tailor-welding tool further comprises a side positioning device located on the right side of the rectangular welding platform and a side jacking device located on the left side of the rectangular welding platform; and the middle of the rectangular welding platform is provided with a jacking, hoisting and positioning device used for eliminating a gap formed between a hydraulic support main rib plate and a top beam top plate. The hydraulic support top beam tailor-welding tool has the advantages that the tailor-welding efficiency is high, the part positioning size precision is high, the finished product size consistency and the interchangeability are high, and tolerance and gap control is precise.

Description

technical field [0001] The invention belongs to the technical field of hydraulic support welding, and in particular relates to a hydraulic support top beam tailor welding tool. Background technique [0002] The top beam is the main part of the hydraulic support. The hydraulic support is one of the important equipment in the modern coal mining face. The top beam is directly in contact with the coal roof and directly bears the pressure from the coal roof. The top beam mostly adopts a box welding structure. It needs to have sufficient strength and toughness to ensure the safety of the coal mining face; because the structure of the top beam is complex and the section of the box-shaped structure changes greatly, it is necessary to strictly control the gap and position size between the parts in the production process to ensure the safety of the coal mining face. Achieve high welding quality and provide a basis for the processing of hinge holes and subsequent assembly work. In the...

Problems solved by technology

In the original production process, the relative size is mostly controlled by manual scribing and assembly according to the line. It is difficult to effectively control the relative size of each part and the dimensional consistency of the batch finished product. The subsequent welding deformation is effectively controlled by controlling the gap, and It can reduce the processing allowance of the subsequent sequence to improve the processing efficiency; there are many welding defects in the original production process, and the position size and the flatness and straightness of the parts during the processing process are not easy to guarantee, resulting in rework during the production process, making High production cost and low production efficiency
