However, due to the structure of the existing positioning pin, that is, the existing positioning pin is usually a smooth round rod structure, the existing positioning car walking mechanism often appears the phenomenon of reducer shaking, oil leakage and brake damage caused by the disengagement of the reducer positioning pin during operation, thereby increasing the frequency of disassembly and inspection of the whole positioning car walking mechanism.

[0004] At the same time, due to the large diameter size of the brake disc used in the brake system of the existing positioning car walking mechanism, the reducer guard cannot be directly taken out during the disassembly and maintenance replacement of the reducer, and the brake system part needs to be disassembled, thereby causing the time-consuming and laborious whole disassembly process, and often taking more than 12 hours for the disassembly and maintenance of the reducer, thereby seriously affecting the increase of unloading efficiency and vehicle port parking time, and increasing the maintenance cost. UTILITY MODEL CONTENTS

[0005] The utility model aims at the oil leakage, damage accidents and low disassembly efficiency of the brake system in the positioning car walking mechanism during the operation of the existing positioning car walking mechanism, proposes and designs a positioning pin for positioning car walking mechanism and positioning car walking mechanism to overcome the above problems, thereby reducing the disassembly and inspection time of the positioning car walking mechanism and improving the unloading efficiency.

[0006] In order to achieve the above purpose, the technical scheme provided by the utility model is as follows: a positioning pin for positioning car walking mechanism, which comprises a cylindrical rod body, the lower end of the cylindrical rod body is provided with a chamfer, the upper end of the cylindrical rod body is provided with a shoulder, the upper end of the shoulder is provided with an internal thread hole, and a threaded plug is screwed in the internal thread hole. At this time, when the positioning pin provided by the utility model is applied, on the one hand, the whole positioning pin can be axially blocked through the shoulder part, thereby effectively avoiding the sinking and falling of the positioning pin, and on the other hand, the internal thread of the positioning pin can be effectively protected from damage by external force and rust while the positioning pin is conveniently disassembled, thereby improving the maintenance efficiency.

[0007] Further, the diameter of the shoulder is 36mm, the diameter of the cylindrical rod body is 30mm, and the positioning pin is blocked by the shoulder, effectively avoiding the sinking and falling of the positioning pin.

[0008] Further, the diameter of the hole of the internal threaded hole is 20mm.

[0009] In addition, the utility model provides a positioning car walking mechanism, it includes the positioning pin for positioning car walking mechanism of above.

[0010] Further, it also includes a drive motor, the output shaft of the drive motor is drivingly connected with a speed reducer, the output shaft of the speed reducer is provided with a hydraulic disc brake and a wheel assembly, the outer diameter of the brake disc of the hydraulic disc brake is smaller than the hole diameter of the lower shoulder of the speed reducer, so that the support can be directly taken out from bottom to top without disassembling the brake disc, thereby improving the disassembly and inspection efficiency of the speed reducer.

[0011] Further, the outer diameter of the brake disc is 530mm, and the hole diameter of the lower shoulder of the speed reducer is 540mm.

[0012] From the above technical solution, the utility model has the following advantages: the utility model not only solves the problem of high time consumption in disassembly and inspection of the speed reducer, but also eliminates the phenomenon of loosening and damage of the speed reducer caused by the falling and sinking of the positioning pin, maximally reduces the factors affecting the maintenance efficiency, and achieves the effect of reducing the maintenance cost and time.
