Embodiment 1

[0029] Embodiment 1: see Figure 1-Figure 7 , a method for repairing an intermediate junction point, the repair method comprising the following steps:

[0030] 1) Rack cleaning; the rack cleaning: classify the front and rear racks of the equipment, rinse them with clean water, and then use a cleaning agent for further cleaning to eliminate oil stains at the intermediate junctions.

[0031] 2) Design "T" type sinker; the step 2) design "T" type sinker; make "T" type sinker: as image 3 As shown, prepare "T" type countersinking sleeves of the same size, and repair the junction points in the middle of the front and rear racks separately, and the repair method of the front and rear frames is the same. For example, when repairing the junction point in the middle of the front rack, put the "T" type countersink into the connection hole of the junction point in the middle of the equipment rack in turn;

[0032] 3) Design an infrared triangle brace to find the center point device; th...

Abstract

The invention relates to a method for repairing an intermediate handover point. The repair method includes the following steps: 1) Cleaning the frame; 2) Designing a "T" type sinking sleeve; 3) Designing a device for finding the center point of an infrared triangular brace; 4) Designing an up and down The splint is fixed symmetrically, and the welding method is heated symmetrically during welding. 5) Design the fixing bracket, 6) After the boring is completed, wear-resistant treatment. Using the method of repairing the intermediate junction of sinking sleeves does not require dismantling the front and rear frames of the equipment, and does not require large-scale lathe boring, which reduces the labor of maintenance personnel and improves the efficiency of equipment maintenance; using the repairing method of intermediate junctions of sinking sleeves, the equipment The multi-layer intermediate hole at the intermediate junction ensures concentricity and reduces wear on the intermediate junction during equipment operation.

Description

technical field [0001] The invention relates to a repairing method, in particular to a repairing method of an intermediate handover point, and belongs to the technical field of mechanical maintenance of mining equipment in underground mines. Background technique [0002] There are currently 28 trackless equipment used underground, 13 trolleys and 6 other auxiliary equipment. All trackless equipment adopts the hinged structure of the front and rear racks. In recent years, with the increase of the service life of the equipment, the wear of the middle hinge point has become more and more serious, the reference holes of the front and rear racks of the equipment have been severely worn and deformed, and the gap between the middle hinge points has become larger and larger, resulting in the non-concentric connection holes of the middle junction points of the rack. affect the safe operation of the equipment. [0003] The middle junction point is severely worn and needs to be repai...
