[0002] Mining tunneling machines play a crucial role in underground mining operations, serving as key equipment for improving mining efficiency and ensuring construction safety. The structure of a mining tunneling machine includes a main frame, traveling sections at both ends of the main frame, a shovel at the front of the main frame, and a tunneling head mounted above the main frame. When tunneling machines are operating in coal mines, slippery ground conditions and insufficient traction between the tracks and the ground can easily lead to track slippage, affecting the progress of the operation and mining efficiency.

[0010] The anti-slip type track frame for mining tunneling machines is characterized in that: the straight anti-slip ribs and the L-shaped anti-slip ribs are located at the rear end of the pin connecting seat.
[0011] The advantages of the anti-slip track frame of this utility model are as follows: 1. By improving the surface structure of the track and adding ribs (ground ribs), and arranging them in a symmetrical manner, the shear force between the ribs and the ground is used to increase the adhesion between the track and the ground; 2. The combination of straight anti-slip ribs and L-shaped anti-slip ribs can greatly improve the shear force between the track and the ground, thereby improving the anti-slip strength.

[0019] Reference Figure 1-6 As shown, the anti-slip track frame of this utility model for a mining tunneling machine includes a track frame 1 and a track 2 mounted on the track frame 1. A drive wheel 3 and a tension wheel 4 are respectively provided at both ends of the track frame 1. The drive wheel 3 drives the track 2 forward, and the tension wheel 4 tensions the track 2. The track 2 consists of a set of track plates 5 and pins 6 connected to the track plates 5. A drive hole 7 is provided in the middle of the track plate 5, and the teeth 8 of the drive wheel 3 mesh with the drive hole 7. A set of spaced-apart first grooves 9 are provided on both sides of the track plate 5 corresponding to the drive hole 7. Two spaced-apart straight anti-slip ribs 10 are provided on the front sides of both sides of the track plate 5 corresponding to the drive hole 7, and two spaced-apart L-shaped anti-slip ribs 11 are provided on the rear edges of both sides of the track plate 5 corresponding to the drive hole 7.
[0020] Preferably, the included angle of the L-shaped anti-slip rib 11 is 90° < α < 130°. Ideally, the included angle of the L-shaped anti-slip rib 11 is α = 120°, to achieve optimal friction with the ground.
[0021] Preferably, the track plate 5 has a set of spaced-apart pin connecting seats 12 at both ends, and the end face of the pin connecting seat 12 has a second groove 13. The second groove 13 increases the friction with the ground, thereby further improving the anti-slip effect.
[0022] Preferably, the track plate 5 has a boss 14 corresponding to the drive hole 7, and the tension wheel 4 acts on the boss 14. The boss 14 is provided to improve the strength of the track plate 5.
[0023] Preferably, the upper end of the track frame 1 is provided with a track tray 15 supporting the track 2. The track tray 15 includes a base plate 16, an arc-shaped panel 17 disposed on the base plate 16, and a top plate 18 disposed in the middle of the arc-shaped panel 17. The track tray 15 prevents the lower vertical part of the track 2 from contacting the track frame 1, thereby reducing the wear and resistance of the track frame 1.
[0024] Preferably, the straight anti-slip rib 10 and the L-shaped anti-slip rib 11 are located at the rear end of the pin connecting seat 12. Since the force is greatest at the pin connecting seat 12, the shear force of the straight anti-slip rib 10 and the L-shaped anti-slip rib 11 can be improved.
[0025] As stated above, this is not intended to limit the present invention in any way. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed structure and technical content to create equivalent embodiments without departing from the scope of the present invention. However, any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
