Abstract

The invention provides a mine car pull rod seat welding maintenance method. A pull rod seat is prevented from being integrally cut, only parts, provided with holes, on old side plates (a first side plate and a second side plate) are cut off, and repair welding of new side plates (a third side plate and a fourth side plate) are carried out at the cutting positions; and specifically, the old first side plate is firstly cut off, spot welding is carried out on the new third side plate with the old second side plate as a standard, then the old second side plate is cut off, the new fourth side plateis arranged with the new third side plate as a standard, and the third side plate and the fourth side plate are welded to the original cut-off positions, so that the consistency of the positions of pin holes in the new side plates and pin holes in the old side plates is effectively guaranteed, and maintenance and replacement of the pull rod seat can be achieved under the condition that an original pull rod seat is not disassembled.

Description

technical field [0001] The invention relates to the technical field of maintenance of a tie rod seat of a mine car, in particular to a method for welding and repairing a tie rod seat of a mine car. Background technique [0002] The tie rod seat of the 60-ton mining dump truck is the connection interface between the power system and the frame, and is located under the steel structure of the frame. It is integrated with the steel structure of the frame by welding. [0003] Due to the heavy load, heavy tasks and harsh working conditions of the mining dump truck, the connecting hole on the tie rod seat connected to the power system gradually wears out, and its shape gradually changes from round to oval. If you continue to use it, there will be a big security risk. Therefore, it is necessary to consider repairing the tie rod seat. [0004] To realize the repair of the tie rod seat, the traditional method is to ship the whole vehicle from the mine to the company's manufacturing ...
