The invention relates to an auxiliary supporting rod assembly and a coal cutter walking box hoisting method, the supporting rod assembly comprises a supporting rod and a nut, the head end and the tail end of the supporting rod are each provided with an external thread section, the middle of the supporting rod is a polished rod section, and the external thread section at the tail end can be screwed with the nut; the hoisting method comprises the following steps: (1) enabling the traction part to be in a horizontal state, and hoisting the walking box to be close to the traction part; (2) enabling a supporting rod to respectively penetrate through U-shaped notches in the end surfaces of the left side and the right side of the walking box, screwing the head end of the supporting rod into a shell of the traction part, sleeving a chain on the supporting rod to hoist the walking box in a vertical state, screwing a nut at the tail end of the supporting rod, and hoisting the walking box to be close to the traction part; (3) pushing the walking box towards the traction part, (4) finely adjusting the position of the walking box to enable the walking box to be aligned with the positioning seam allowance of the traction part, and (5) detaching the chain and the supporting rod assembly, and installing screws to fix the walking box on the traction part. The device can be used for the underground operation environment, is simple and efficient, can improve the installation efficiency of the walking box, and remarkably reduces the operation intensity.

    本发明涉及一种辅助支撑杆组件及采煤机行走箱吊装方法,所述支撑杆组件包括支撑杆和螺母,支撑杆的头、尾端均设有外螺纹段,中间为光杆段,尾端的外螺纹段与螺母能相互旋合;所述吊装方法包括步骤:1)使牵引部处于平放状态,将行走箱吊至牵引部附近,2)用支撑杆分别穿过行走箱左右两侧端面上的U形豁口,将支撑杆头端旋进牵引部壳体,将链条套在支撑杆上将行走箱呈竖直状态吊起,把螺母拧紧在支撑杆尾端,3)将行走箱向牵引部推进,4)微调行走箱的位置使行走箱与牵引部的定位止口对齐,5)卸下链条和支撑杆组件,安装螺钉将行走箱固定在牵引部上。本发明能用于井下作业环境,简单高效,能提高行走箱的安装效率,显著降低作业强度。
