Description

Technical Field

[0001] The utility model belongs to the technical field of track switches for rack rail clamping vehicles in mines, and in particular relates to a crossover switch device for switching bidirectional tracks of rack rail clamping vehicles. Background Art

[0002] As the main auxiliary transportation equipment in coal mines, rack rail cars undertake important transportation tasks. Due to the special structure of the rack rail cars, it is necessary to lay special rack rail car tracks from the ground yard to the bottom of the mine. The traditionally laid tracks are one-way "Y" tracks, which are forked at the fork. When multiple vehicles are working at the same time, the vehicles meet each other, which is inconvenient to change lanes and affects work efficiency. This track is suitable for small mines. With the development of large mines, higher requirements are put forward for the transportation capacity and efficiency of rack rail cars. Bidirectional rack rail car tracks are applied, but it is still inconvenient for rack rail cars to change lanes on bidirectional tracks, which affects transportation efficiency.

[0033] like Fig.10 As shown, the left-opening crossover turnout structure is centrally symmetrical with the right-opening crossover turnout structure.

[0034] Working principle: rack rail car No. 1 runs on the left track, rack rail car No. 2 runs on the right track, when rack rail car No. 1 needs to switch from the left track to the right track; the upper and lower sides of the right turnout are carried out simultaneously, first the small cylinder 6 contracts to drive the pin shaft rotating plate 13 to move, but the pin shaft rotating plate 13 can only rotate around the cylinder seat 130, the positioning pin shaft 14 moves backward, so that the one-meter straight rail 7 with the sliding sleeve is unlocked from the straight rail 2 17, and then the large cylinder 9 begins to extend, pushing the sliding rail 5 to move; because the bottom of the sliding rail 8 is fixed to the channel steel, the sliding rail 5 moves on the surface of the long guide rail assembly 13, the long guide rail assembly 24, and the sliding rail 8 through the short guide 15; on the surface of the steel pipe 11 and the steel pipe 2 12 of the long guide rail assembly 13 and the long guide rail assembly 24, there are wear-resistant strips 122 and 25 to make the sliding rail 5 move more smoothly and prevent rust. When the sliding track 5 moves to the limited position of the sliding block 21 and the sliding block 4 24, the large oil cylinder 9 stops extending, the small oil cylinder 6 starts to extend, and the positioning pin shaft 14 moves forward, and the one-meter straight rail 7 with the sliding sleeve is locked with the curved track 18 through the sliding sleeve 1 28 and the sliding sleeve 29. At this time, the No. 1 rack rail car can smoothly change tracks, and the stop plate 27 is fixed on the short guide 15. When the sliding track 5 moves, the stop plate 27 also moves to the appropriate position, and the stop plate 27 intersects with the one-meter straight rail 1 to prevent the No. 2 rack rail car running on the right track from falling off the track.

[0035] When the No. 1 rack rail car has finished changing lanes, the upper and lower sides of the right turnout are opened simultaneously, the small oil cylinder 6 begins to shrink, the positioning pin shaft 14 moves backward, and the sliding rail 5 is unlocked; the large oil cylinder 9 begins to shrink, pulling the sliding rail 5 to move; the sliding rail 5 moves on the surface of the long guide rail assembly 1 3, the long guide rail assembly 2 4, and the sliding rail 8. After the sliding rail 5 moves to the sliding block 1 20 and the sliding block 3 23, the large oil cylinder 9 stops shrinking, the small oil cylinder 6 begins to extend, and the positioning pin shaft 14 moves forward, and the one-meter straight rail with the sliding sleeve is locked with the straight rail 2 17 through the sliding sleeve 1 28 and the sliding sleeve 2 29; after the No. 1 rack rail car successfully completes the lane change, the No. 2 rack rail car can continue to drive straight to operate.

[0036] The working principle of the left-opening crossover turnout is the same as that of the right-opening crossover turnout.
