[0018] The utility model is further explained and illustrated below in conjunction with the accompanying drawings:

[0019] Example 1, see Figure 1-Figure 4 A rotating track for a material transport vehicle in an underground coal mine comprises a support rod 1, a turntable 3 and a track bottom plate 4. The support rod 1 is inserted into the ground, a pressure plate 2 is arranged on the top of the support rod 1, a turntable 3 is rotatably connected above the pressure plate 2, a track bottom plate 4 is arranged above the turntable 3, tracks 401 are respectively arranged on both sides of the track bottom plate 4, and a limiting hook plate 5 is arranged at the end of the track 401.

[0020] Support pillars 6 are arranged around the bottom of the turntable 3 . There are four support pillars 6 , which are evenly distributed on the ground A. A roller 7 is arranged on the top of each support pillar 6 .

[0021] The pressing plate 2 and the supporting rod 1 are an integrated structure. An insertion hole B is dug on the ground A, and the supporting rod 1 is inserted into the insertion hole B. The pressing plate 2 is fixedly connected to the ground A by bolts 8.

[0022] A limiting hole 301 is dug at the center of the top surface of the turntable 3 , and a plug post 405 is provided at the center of the bottom surface of the track bottom plate 4 . The position of the plug post 405 corresponds to the position of the limiting hole 301 .

[0023] A positioning ring 402 is provided on the inner side of one end of the track 401. There are two positioning rings 402, and plug rods 403 are inserted into the two positioning rings 402. A limiting hook plate 5 is provided in the middle of the plug rod 403. The limiting hook plate 5 is buckled on the track 401, and an plug plate 404 is provided on the track 401 below the limiting hook plate 5. The track 401 is fixedly connected to the positioning ring 402 by bolts.

[0024] In the above description, there are two tracks on each track base plate, and a limiting hook plate is arranged at the end of each track, and the two limiting hook plates are symmetrically distributed, that is, a limiting hook plate is arranged at the left end of one of the tracks, and a limiting hook plate is arranged at the right end of the other track.

[0025] In the above description, the insertion rod can be rotated in the positioning ring. By rotating the insertion rod, the limit hook plate can be buckled on the track. At this time, there is a gap between the limit hook plate and the track. The gap is blocked by inserting a column in the gap, and then the insertion rod is fixed by the bolts outside the positioning ring. Because the insertion rod and the limit hook plate are fixed together, the insertion rod is fixed, and the limit hook plate can also be fixed.

[0026] In the above description, the turntable and the track base plate are plug-in connected, and both ends of the track base plate extend out of the ends of the turntable, and the height of the track stacked on the base plate is consistent with the height of the tracks on both sides of the intersection.

[0027] In the above description, a rotating mechanism is provided between the turntable and the pressure plate. When in use, the direction of the track bottom plate can be changed by manually rotating the turntable.

[0028] Specific construction method:

[0029] S1. Dig a hole B on the ground at the track intersection, make the depth of the hole B greater than the length of the support rod 1, insert the support rod 1 into the hole B, make the pressure plate 2 located on the ground B, and fix the pressure plate 2 to the ground with bolts;

[0030] S2. According to the outer diameter of the turntable 3, the roller 7 is installed on the ground B below the turntable 3. After the turntable 3 is installed, the track base plate 4 is installed on the turntable 3 so that the plug 405 at the bottom of the track base plate 4 is inserted into the limit hole 301;

[0031] S3. After the installation is completed, the material transport vehicle can be used. When the material transport vehicle moves to the rotating track, the limit hook plate 5 at the right end of one of the tracks 401 is opened, and the plug plate 404 there is removed, and then the limit hook plate 5 at the left end of the other track 401 is buckled on the corresponding track 401, and the plug plate 404 is inserted on the track 401 below the limit hook plate 5, and the bolts outside the positioning ring 402 are tightened to fix the limit hook plate 5 on the track 401;

[0032] S4, after the limit hook plate 5 is arranged, the turntable 3 is rotated to align the right end of the track 401 with the track on the right, and then the staff quickly moves the material transport vehicle to the track bottom plate 4, and buckles the limit hook plate 5 at the right end of one of the tracks 401 on the corresponding track 401, and fixes the limit hook plate 5 with bolts. At this time, both limit hook plates 5 are buckled on the track 401;

[0033] S5. The staff rotates the turntable again to align the left end of the track 401 with the track on the left, opens the limit hook plate 5 at the exit end of the track 401, and removes the plug plate 404. The material transport vehicle quickly passes through the rotating track and walks on the normal track.

[0034] When in use, when the mine car moves from right to left along the track to the intersection, at this time, it is necessary to open the limit hook plate on the right end of the track bottom plate, and buckle the limit hook plate on the left end of the track bottom plate on the track, so that when the transport trolley enters the track bottom plate, it will not rush down from the track bottom plate; when the mine car is completely moved to the track bottom plate, it is necessary to buckle the just opened limit hook plate on the track again and fix it with bolts. At this time, the two limit hook plates on the track bottom plate are in a merged state, and the staff can turn the turntable to change the moving direction of the mine car.

[0035] After the staff has adjusted the direction of the turntable, they only need to open the limit hook plate at the exit end, and the mine car can quickly move to the track on the other side of the intersection.

[0036] In the above description, during construction, it is necessary to dig grooves and holes at the intersection of the curves so that the height of the track piled on the bottom plate is consistent with the height of the tracks on both sides of the intersection of the curves.

[0037] The rotating turnout has been used at the intersection of the transport chute connecting tunnel and the outer section of the transport chute. When transporting materials, it is no longer necessary for manual labor to unload the materials first and then hang them under the monorail. Now it is only necessary to push the mine car onto the rotating turnout manually, and then use the rotating turnout to rotate the mine car 90 degrees, so that the direction of the mine car body is consistent with the travel direction of the monorail, which is convenient for the monorail to lift materials.

[0038] The utility model arranges rollers around the bottom of the turntable, which not only play a supporting role, but also facilitate the overall rotation under the action of the driving mechanism, so that the mine car can be quickly rotated at a 90-degree intersection, so that the direction of the mine car body is consistent with the walking direction of the monorail crane, reducing the labor intensity of underground workers, improving work efficiency, and being easy to promote.
