[0002] Underground track is one of the main facilities for transporting coal and personnel in coal mines. Its quality and safety have a significant impact on production safety and the entire process of coal production. The track structure of underground track includes multiple parts such as sleepers, rail seats, switches, and diamond tracks. Among them, sleepers are an important part of supporting the track. The most commonly used sleepers are wooden sleepers and concrete sleepers. The fixation of the track is also a key link to ensure its stability and safety. The main fixing methods currently used include elastic clamping, sand squeezing, and pre-embedded methods.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figure 1 、 2 As shown in Figures 3 and 4, this embodiment proposes an underground track resetter, including a base plate 1, a rectangular frame 2, a No. 1 guide rail 3 and a No. 2 guide rail 4, one end of the base plate 1 is fixedly connected to the rectangular frame 2, one side of the rectangular frame 2 is fixedly connected to the No. 1 guide rail 3, and the other side of the rectangular frame 2 is fixedly connected to the No. 2 guide rail 4. A supporting mechanism is provided at the end of the base plate 1 away from the rectangular frame 2, and the entire resetter is set on the underground track through the rectangular frame 2. The rail car can be powered by an electric locomotive, a battery locomotive, or a winch to move the wheel hub at its bottom to the track through the No. 1 guide rail 3 or the No. 2 guide rail 4, wherein the supporting mechanism can play a limiting role to prevent the rail car from offsetting during movement.

[0020] One side of the No. 1 guide rail 3 and the No. 2 guide rail 4 is provided with a No. 1 slot 6, and the No. 1 guide rail 3 and the No. 2 guide rail 4 are welded to the rectangular frame 2 through the No. 1 slot 6. The outer side of the No. 2 guide rail 4 is fixedly connected with a handle. The No. 1 guide rail 3 and one side of the No. 2 guide rail 4 are placed on the top of the rectangular frame 2 through the No. 1 slot 6, and then the No. 1 guide rail 3, the No. 2 guide rail 4 and the rectangular frame 2 are welded together using a welding gun to connect the rectangular frame 2, the No. 1 guide rail 3 and the No. 2 guide rail 4 into a whole. The entire resetter can be lifted by the handle, which is convenient for driving the entire resetter to move.

[0021] The support mechanism includes a bracket 8, a threaded sleeve 9, a threaded rod 10, a bearing 11 and a pressure block 12. The bottom plate 1 is fixedly connected to the bracket 8 at one end away from the rectangular frame 2. The top of the bracket 8 is provided with a threaded sleeve 9. The internal thread of the threaded sleeve 9 is connected to the threaded rod 10. One end of the threaded rod 10 is rotatably connected to the pressure block 12 through the bearing 11. The shape of the pressure block 12 is set as a conical structure. The shape of the No. 1 guide rail 3 and the No. 2 guide rail 4 is set as a ramp structure. The bottom end of the No. 1 guide rail 3 is overlapped on the sleeper. Because the threaded rod 10 is threadedly matched with the threaded sleeve 9, and the pressure block 12 is rotatably connected to the threaded rod 10 through the bearing 11, the forward and reverse rotation of the threaded rod 10 can drive the pressure block 12 to move back and forth in a straight line along the length direction of the threaded sleeve 9, adjusting one side of the pressure block 12 to a position parallel to one side of the track, and the pressure block 12 of the tapered structure is more in line with the outer wall of the rail car, so as to support the rail car and avoid displacement when the rail car moves.

[0022] A support rail 7 is provided at the top of the rectangular frame 2, and a second slot 15 is provided at the bottom of the support rail 7. The inner wall of the second slot 15 is welded to the top of the rectangular frame 2. A slope is provided on one side of the support rail 7, and the bottom end of the slope is fitted and connected to the track. After the wheel hub of the railcar moves to the top of the track through the No. 1 guide rail 3 or the No. 2 guide rail 4, it continues to move forward and slides onto the track through the slope on the support rail 7 to complete the reset of the entire railcar.

[0023] A group of threaded holes 13 are symmetrically provided on both sides of the rectangular frame 2. The internal threads of the threaded holes 13 are connected to the fastening bolts 5. The interior of the fastening bolts 5 is provided with a hexagonal hole 14. After the rectangular frame 2 is set on the track, the hexagonal wrench is inserted into the hexagonal hole 14, and the fastening bolts 5 are driven by the hexagonal wrench to rotate, so as to screw the fastening bolts 5 toward the track. The fastening bolts 5 on both sides tighten the rectangular frame 2 and the track, making the position of the rectangular frame 2 on the track more stable, thereby preventing the rail car from offsetting when resetting.

[0024] The rectangular frame 2, the first guide rail 3 and the second guide rail 4 are all made of alloy steel. The first guide rail 3 and the second guide rail 4 form an eight-shaped structure. The trailer rail 7 is at the same height as the top of the first guide rail 3 and the second guide rail 4.

[0025] The downhole track resetter is installed on the downhole track through a rectangular frame 2. The track car can be powered by an electric locomotive, a battery locomotive, or a winch to move the wheel hub at its bottom onto the track through the No. 1 guide rail 3 or the No. 2 guide rail 4. The forward and reverse rotation of the threaded rod 10 can drive the pressure block 12 to move back and forth in a straight line along the length direction of the threaded sleeve 9, and adjust one side of the pressure block 12 to a position parallel to one side of the track. The tapered structure of the pressure block 12 fits more closely with the outer wall of the track car, thereby supporting the track car and avoiding displacement when the track car moves.
