[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] Embodiment 1, as Figure 1-2 As shown, the specific design of the above-mentioned key components is described in detail below: the front axle of the mine car includes a main beam 1, and the main beam 1 includes an axle head 101, a side arm 102, and a center beam 103. The axle head 101 is columnar in design and a mounting hole I is arranged in the center of the axle head 101. The mounting hole passes through the axle head 101 along the axis of the axle head 101, one end of the side arm 102 is connected to the axle head 101, and the center beam 103 is horizontally connected to the other end of the side arm 102 away from the axle head 101, and the side arm 102 and the axle head 101 are centrally symmetrically arranged about the center beam 103.

[0020] A bracket II is symmetrically arranged on the center beam 103 near the shaft head 101 by bolt connection or welding. The orientation of the bracket II is consistent with the axial direction of the shaft head 101. A mounting hole II is arranged on the bracket II, and the mounting hole II is used to connect with the oil and gas suspension of the mine car. In this embodiment, in order to enhance the strength of the bracket II, the cross section of the bracket II can be regarded as a right-angle trapezoidal arrangement. In order to facilitate the arrangement of the mounting hole II, its short side is arranged into a semicircle for convenient connection. At the same time, in order to facilitate the connection, a connecting through groove is arranged in the center of the bracket II, and the direction of the connecting through groove is arranged at a vertical angle to the direction of the mounting hole II. In this way, the bracket II forms a structural design of a base and a side plate, so as to facilitate the connection with the XX part of the mine car.

[0021] In order to facilitate the connection with the thrust rod of the mine car, a U-shaped bracket III is symmetrically arranged on the center beam 103 through bolts. Bracket III is arranged on the side of bracket II away from the shaft head 101. Bracket III is arranged in a U shape as a whole. Considering its connection with the thrust rod, in this embodiment, both ends of bracket III are arranged in a square column shape, and a mounting hole III is arranged on the top of bracket III, and the mounting hole III is arranged on the side wall of bracket III.

[0022] In order to strengthen the strength of the center beam 103, a groove 6 is opened on one side of the center beam along the length direction of the center beam 103. The groove 6 is set for two purposes. One purpose is to strengthen the strength of the entire center beam 103, and the other purpose is to improve the strength of the connection with the other end of the thrust rod. For this purpose, a bracket I is provided on the side of the groove 6 adjacent to the side arm 102. The bracket I is connected to the side of the center beam 103 by bolt connection or welding. The bracket I is also U-shaped and the two ends of the bracket I are also square columnar. Unlike the bracket III, connection holes are provided on the end faces at both ends of the bracket I.

[0023] In order to further improve the strength of the front axle beam of the mine car, the entire side arm 102 and the center beam 103 are inclined at 30 degrees. The 30-degree inclined design of the side arm 102 makes the front axle beam of the mine car have better strength, stability and controllability, and is smoother during driving.

[0024] In order to further increase the connection strength, a reinforcing rib 8 is provided at the bottom of the bracket III, which enhances the bearing capacity and stability of the bracket III and improves the strength of the overall structure.

[0025] At the same time, the surface of each component is smoothed to reduce friction and wear between components, extend service life and improve operating efficiency. Bracket I, bracket II and bracket III are made of alloy steel or ductile iron and the surface is anti-corrosion treated to effectively prevent components from corrosion and damage and ensure the stability and reliability of the front axle of the mine car.

[0026] In this embodiment, the shaft head 101, the side arm 102 and the center beam 103 are forged into an integral main beam 1, ensuring that the side arm 102 is inclined at 30 degrees, so that the connection between the fixed parts is firm, and the bracket II is symmetrically arranged on the center beam 103 near the shaft head 101 by welding or bolting, and a mounting hole II is designed thereon; the U-shaped bracket III is symmetrically arranged on the bracket II near the center beam 103 by bolts, ensuring that the bracket III is firmly fixed on the center beam 103, and the U-shaped design makes the connection more stable and more convenient, so that it is convenient for the bracket III to install other components through the mounting hole I, and the surface of the overall main beam 1 structure is smoothed to ensure that the surface of the components is flat and smooth, and the overall appearance and service life are improved. Through the above design, the stability, durability and use efficiency of the front axle of the mine car can be improved, ensuring that the mine car can run smoothly in harsh environments.
