Description

Technical Field

[0001] The present invention relates to the technical field of train safety, and in particular to a system for ensuring safe travel of trains under icy and snowy conditions. Background Art

[0002] When a train starts on smooth tracks, wheelspin and slip can occur. Besides starting, trains can also experience slippage when encountering rain, snow, or frost, especially when climbing a slope or braking in the former. Train slippage is caused by adverse weather and other factors, and not only affects locomotive performance but also poses a significant risk of accidents. To combat wheel slippage, sanding the rails has long been used to increase friction and prevent slippage.

[0003] However, traditional sand-spreading devices all install a sandblasting nozzle in front of the wheel and then spray sand on the track through the sandblasting nozzle. Because the track surface is covered with snow, the sprayed sand will accumulate on the snow, resulting in poor anti-skid effect after sanding. In addition, because the sandblasting nozzle is always located at the wheel, it is easy to be clogged by dust or other factors during long-term train travel, thus affecting the sandblasting effect of the sandblasting nozzle in icy and snowy weather. To this end, we propose a system to ensure the safe operation of trains in icy and snowy conditions. Summary of the Invention

[0049] In this way, the snow on the train track can be removed by the snow removing mechanism 3, and the quartz sand particles are sprayed on the rail surface in front of the running direction of the wheel by the sand blasting head 5, and the wheel rolling over the quartz sand particles can increase the friction between the wheel and the rail, thereby effectively preventing the wheel from slipping, ensuring that the train in the running stops within the specified braking distance, thereby providing protection for the safe running of the train under the ice and snow conditions.

[0054] In the preferred technical scheme of the embodiment, the recovery mechanism 6 comprises a vertical column 61 fixedly installed at the bottom end inside the secondary box body 2 and a vertical plate 64, a lifting cylinder 62 is slidingly installed outside the vertical column 61, a sliding groove 621 is formed in the outer wall surface of the lifting cylinder 62, the sliding groove 621 is linear at both ends and arc-shaped in the middle, the arc-shaped structure is used to realize the rotation of the lifting cylinder 62, a cylinder plate 68 is rotatably installed at the top end of the lifting cylinder 62, a supporting plate 66 is fixedly installed on one side of the outer wall of the lifting cylinder 62, a round rod 65 is fixedly installed on one side of the outer wall of the vertical plate 64, one end of the round rod 65 away from the vertical plate 64 extends into the sliding groove 621, the diameter of the round rod 65 is consistent with the width of the sliding groove 621, a press switch 63 is fixedly installed at the bottom end inside the secondary box body 2 and located below the lifting cylinder 62, and the press switch 63 is a non-self-locking button switch.

[0055] In this way, when the cylinder plate 68 moves downward, the lifting cylinder 62 will also move downward, at this time, since the round rod 65 is located in the sliding groove 621 and is fixed, the lifting cylinder 62 will move downward along the track of the sliding groove 621 while rotating, the rotating direction is 90 degrees, so the sand blasting head 5 can be moved out of the secondary box body 2 by the supporting plate 66 and located above the track of the train, when the cylinder plate 68 drives the lifting cylinder 62 to move upward, the sand blasting head 5 will be recovered from above the track of the train into the secondary box body 2, so that the sand blasting head 5 can be moved out when the train slips and recovered when the train does not slip, which can avoid the damage of the sand blasting head 5 caused by the long-term location of the sand blasting head 5 above the track and the blockage of the sand blasting head 5.

[0056] It should be noted that when the lifting cylinder 62 rotates the sand blasting head 5 by 90 degrees to move above the track of the train, at this time, the lifting cylinder 62 will also descend to the bottom end of the secondary box body 2, and the lifting cylinder 62 will contact the press switch 63, so the air compressor 9 and the electromagnetic valve 42 can be turned on by the press switch 63, at this time, the quartz sand particles in the sand cylinder 41 will enter into the sand blasting head 5 along the sand guide hose 43 and then sprayed from the sand blasting head 5, when the sand blasting head 5 is recovered from above the track of the train into the secondary box body 2, the lifting cylinder 62 will also move away from the press switch 63, at this time, the press switch 63 is powered off, so the air compressor 9 and the electromagnetic valve 42 can be turned off, which can prevent the quartz sand particles in the sand cylinder 41 from flowing out and avoid the waste of the quartz sand particles.

[0060] In this way, the quartz sand particles in the sand guide hose 43 enter the sand blasting head 5 through the sand inlet pipe 52 and are then blasted out of the sand blasting head 5. Since the sand guide hose 43 is made of soft material and has a length left inside the secondary box body 2, the removal of the sand blasting head 5 is not affected.

[0062] In this way, when the sand blasting head 5 is moved out of the sub-box 2, the protection mechanism 8 is also moved out, at this time, the two hinged plates 82 are moved out of the two inclined plates 671, when the hinged plates 82 lose the extrusion force of the two inclined plates 671, the two hinged plates 82 are unfolded outward under the elastic force of the torsion spring, and the protection cover 86 is turned over around the shaft 81, so that the two protection covers 86 are in an open state, so that the sand blasting head 5 is exposed, when the sand blasting head 5 is retracted into the sub-box 2, the rollers 85 at the ends of the two hinged plates 82 are first rotated to the bottom of the hinged plate 82, and then the hinged plate 82 is moved upward in a straight line, because the spacing of the two inclined plates 671 is smaller and smaller upward, so that the two hinged plates 82 are extruded, so that the two protection covers 86 are rotated to each other, so that the sand blasting head 5 is wrapped, so as to avoid the sand blasting head 5 from being blocked by dust or other pollution when not in use, and ensure that the sand blasting head 5 can stably sand at the critical moment.

[0065] Working principle: when the motor train brake control system autonomously judges that the wheel is idling or sliding, the air cylinder 314 can be controlled to work, and the air cylinder 314 drives the lifting plate 315 to move downward, so that the snow shovel plate 32 and the snow shovel plate 33 can be lowered to the train track, and the snow on the track can be removed by the snow shovel plate 32. When the lifting plate 315 moves downward, the guide column 35 will also move downward, so that the connecting rod 74 can be driven to move downward through the sliding support 75, so that the sliding block 72 will also move downward, so that the cylinder plate 68 can be driven to move through the connecting seat 73, and the lifting cylinder 62 will move downward, at this time, since the round rod 65 is located in the sliding groove 621, and the round rod 65 is fixed, therefore, the lifting cylinder 62 will move downward along the track of the sliding groove 621, and rotate at the same time, the rotating direction is 90 degrees, so that the sand blasting head 5 can be moved out of the secondary box body 2 through the supporting plate 66, and the sand blasting head 5 is located above the track of the train, at this time, the lifting cylinder 62 will contact the press switch 63, so that the air compressor 9 and the electromagnetic valve 42 can be turned on through the press switch 63, the quartz sand particles in the sand cylinder 41 will enter the sand blasting head 5 through the sand guide hose 43, and then be sprayed to the track from the sand blasting head 5, the quartz sand particles rolled by the wheels will increase the friction between the wheels and the rails, thereby effectively preventing the wheels from slipping and ensuring that the train stops within the specified braking distance.
