Description
Technical Field
[0001] The invention relates to the field of overhead wire type industrial and mining electric locomotives, and in particular to a multifunctional overhead wire type industrial and mining electric locomotive. Background Art
[0002] my country's coal mining technology has advanced rapidly, significantly improving the mechanization of mining and excavation, significantly increasing recovery efficiency, and significantly reducing the proportion of recovery personnel among underground workers. However, overall efficiency in most Chinese mines remains slow to improve, resulting in low economic returns. While there are many factors contributing to this situation, the backwardness of auxiliary transportation is a major factor.
[0003] Currently, mining electric locomotives produced and used domestically are important auxiliary transportation equipment. These locomotives consist of a carbody and a pantograph mounted on it, a frequency converter, a drive motor, a reduction gearbox, and a driver's control console. The pantograph is in frictional contact with the overhead contact network within the tunnel. The pantograph output is connected to the frequency converter, which in turn is connected to the drive motor, which drives the wheels via the reduction gearbox. The driver's control console panel houses various components for controlling the locomotive, enabling the locomotive to move forward, backward, and stop. Mining electric locomotives also have a fixed sand spreading device, which is used to spread sand onto the rail surface. Under the action of compressed air, sand in the sand bucket is released through a sand outlet pipe and onto the rail surface. Sanding increases the wheel-rail adhesion coefficient, thereby increasing adhesion traction and preventing wheel spin. However, the sand outlet pipe angle of conventional sand spreading devices cannot be adjusted, resulting in poor sanding effectiveness. Furthermore, clogged sand spreading devices are difficult to clean. A multifunctional overhead-trail mining electric locomotive is proposed to address these issues. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting the following technical solutions: a multifunctional overhead wire type industrial and mining electric locomotive according to the present invention comprises a frame, a spring bracket is fixedly connected to the top of the frame, a sand spreading device is symmetrically arranged inside the frame, and the outer surface of the sand spreading device is fixedly connected to the inner wall of the frame;
[0005] The sand spreading device is arranged inside the vehicle frame. By arranging the sand spreading device, the sand spreading angle can be controlled, and the cooperation of the rotating rod and the spiral disk in the storage box can reduce the problem of difficulty in cleaning after the sand spreading device is blocked. The sand spreading device includes a storage box, the top of the storage box is fixedly connected to the motor, the bottom of the motor is rotatably connected to the rotating rod, the outer surface of the rotating rod is fixedly connected to the spiral disk, the bottom of the storage box is fixedly connected to the connecting pipe, the bottom of the connecting pipe is fixedly connected to the sand spreader, and the outer surface of the sand spreader is provided with a guide component. When the sand spreading device is in use, the motor is first used to drive the rotating rod to rotate, thereby causing the rotating rod to drive the spiral disk to rotate in the storage box, thereby causing the agglomerated sand to enter the sand spreader through the connecting pipe and then be discharged through the guide component, and the outer surface of the sand spreader is fixedly connected to the top of the guide component, and the storage box is fixedly connected to a fixed block at one end close to the guide component, and the bottom of the rotating rod is fixedly connected to an extension rod, and the outer surface of the extension rod is provided with a stirring component, and the outer surface of the extension rod is fixedly connected to the top of the stirring component. A discharge rod is connected. Since the orientation angle of the guide component can be controlled, the sand spreading angle can be controlled. The stirring component on the rotating rod can prevent residual sand in the storage box from being discharged. A gap tube is provided inside the connecting pipe. By providing the discharge rod, the uniform flow rate of the sand can be controlled to prevent the sand from entering the storage box into the sandblaster due to the excessively high content of sand ejected in the early stage, which causes the sand in the storage box to be lost too quickly and wasteful. The inner wall of the connecting pipe is fixedly connected to the outer surface of the gap tube. By rotating the discharge rod, the sand flows evenly from the gap between the discharge rod and the gap tube into the connecting pipe, and then the sand is transferred to the guide component through the sand spreader, so that the sand content per unit time in the guide component is relatively uniform, thereby ensuring the sand loss rate. The gap tube is located inside the connecting pipe. By cooperating and rotating between the discharge rod and the gap tube, the agglomerated sand can be broken up, so that the sand on the rail surface is uniform, so that it can stably increase the adhesion coefficient between the wheel and rail, thereby increasing the adhesion traction and preventing the wheel from spinning. The inner wall of the gap tube is in contact with the outer surface of the discharge rod.
[0006] The guide component includes a discharge pipe. By setting the guide component, the direction angle of sand spreading can be controlled. The direction angle of the guide cylinder can be controlled by using the lifting component, so that the guide component can control the sand spreading angle when in use. The outer surface of the discharge pipe is fixedly connected to the connecting cylinder, and the end of the connecting cylinder away from the discharge pipe is fixedly connected to the guide cylinder. Since the connecting cylinder is provided in the guide component, the discharge cylinder and the guide cylinder can still remain connected when the guide cylinder adjusts the angle. The buffer component provided at the bottom of the guide cylinder can reduce the potential energy of the sand when it comes out. Since the surface of the rail surface is small, the sand will not fall too much when it is sprayed onto the rail surface, so that the sprayed sand falls on the rail surface to the greatest extent, thereby ensuring the utilization rate of the sand. The end of the guide cylinder away from the connecting cylinder is fixedly connected to the buffer component, and the outer surface of the guide cylinder is provided with a lifting component, and the outer surface of the guide cylinder is fixedly connected to the inner wall of the lifting component.
[0007] The stirring component includes a collar, and the stirring component is provided to prevent sand from remaining in the storage box. When the rotating rod rotates, the collar drives the support rod to rotate, thereby causing the bottom plate to rotate in the storage box. Since a scratch plate is provided in the bottom plate, the scratch plate will scratch the area at the bottom of the storage box when the bottom plate rotates, thereby causing the sand remaining in the storage box to be discharged from between the discharge rod and the gap tube. The outer surface of the collar is symmetrically provided with a support rod, and the outer surface of the collar is fixedly connected to the top of the support rod, and the bottom of the support rod is fixedly connected to the bottom plate. During the rotation of the stirring component, the agglomerated sand can be broken up, thereby reducing the large pieces of sand from moving to the area between the discharge rod and the gap tube, thereby blocking it and preventing it from being discharged normally. The number of the bottom plates is The top of the lifting plate is fixedly connected to the lifting plate, and the bottom of the lifting plate is fixedly connected to the top of the lifting plate. A buffer cylinder is symmetrically provided on the bottom of the lifting plate, and the bottom of the lifting plate is fixedly connected to the top of the buffer cylinder. A rotating rod is provided on the inside of the lifting plate, and the inner wall of the lifting plate is fixedly connected to the two ends of the rotating rod. A scratch plate is provided on the outer surface of the rotating rod, and the outer surface of the rotating rod is rotatably connected to the top of the scratch plate. A fixed rod is symmetrically provided on the outer surface of the scratch plate, and the outer surface of the scratch plate is fixedly connected to the opposite side of the fixed rod. The end of the fixed rod away from the scratch plate is fixedly connected to a flexible plate.
[0008] The lifting component includes a lifting rod. By setting the lifting component, the direction angle of the guide component can be controlled, and the blocking plate in the fixed tube can be used to control the lifting and lowering, so that the sand remaining in the guide component after the sand spreading device stops can be preserved and discharged again when the sand spreading device is started next time, thereby avoiding waste. The bottom of the lifting rod is rotatably connected to a load-bearing ring, and a limit plate is symmetrically provided at the bottom of the load-bearing ring, and the bottom of the load-bearing ring is fixedly connected to the inner wall of the limit plate. When the lifting component is in use, the movable rod is controlled to move upward by the hydraulic rod, causing the blocking plate to move upward, so that the sand passes from under the blocking plate, thereby reducing the dynamic potential energy of the sand during spraying, reducing the probability of sand falling from the rail surface, and ensuring the utilization of the sand. The top of the blocking plate is fixedly connected to the lifting rod, and the top of the lifting rod is fixedly connected to the placing plate, and the top of the placing plate is fixedly connected to the movable rod, and the top of the movable rod is fixedly connected to the hydraulic rod, and the outer surface of the movable rod is provided with a fixed frame, and the inner wall of the fixed frame contacts with the outer surface of the movable rod, and the outer surface of the movable rod is provided with a guide block, and the outer surface of the movable rod is slidably connected to the inner wall of the guide block, and the outer surface of the guide block is symmetrically provided with a positioning rod, and the outer surface of the guide block is fixedly connected to the inner wall of the positioning rod, and the bottom of the guide block is fixedly connected with a reset spring.
[0009] The buffer component includes a retention frame. By providing the buffer component, the dynamic potential energy of the sand during discharge can be reduced, thereby ensuring the sand content on the rail surface, so that the sand can increase the adhesion coefficient between the wheel and rail, thereby increasing the adhesion traction and preventing the wheel from spinning. A positioning plate is symmetrically provided on the top of the retention frame, and the top of the retention frame is fixedly connected to the bottom of the positioning plate. An elastic plate is provided inside the positioning plate, and the inner wall of the positioning plate is fixedly connected to the top of the elastic plate. A shielding plate is fixedly connected to the bottom of the elastic plate. An inner rod is provided inside the shielding plate. When the sand is ejected from the guide component, it will first accumulate in the guide cylinder. When the gravity of the sand on the shielding plate is greater than the elastic force of the elastic plate, the shielding plate begins to squeeze the elastic plate, so that a gap is generated between the shielding plate and the retention frame, causing the sand to be discharged from the gap onto the rail surface. Since the direction angle of the gap is relatively perpendicular to the rail surface, the utilization rate of the sand is high, and the inner wall of the shielding plate is rotatably connected to the outer surface of the inner rod. The top of the shielding plate is fixedly connected to the top plate.
[0010] The beneficial effects of the present invention are as follows:
[0011] 1. The present invention can control the sand spreading angle by providing a sand spreading device, and the use of the rotating rod and the spiral disk in the storage box can reduce the problem of difficulty in cleaning after the sand spreading device is blocked. When the sand spreading device is in use, the motor is first used to drive the rotating rod to rotate, and then the rotating rod drives the spiral disk to rotate in the storage box, and then the agglomerated sand enters the sand spreader through the connecting pipe, and then is discharged through the guide component. Since the direction angle of the guide component can be controlled, the sand spreading angle can be controlled, and the stirring component on the rotating rod can be used to prevent residual sand in the storage box from being unable to be discharged.
[0012] 2. The present invention can control the uniform flow rate of sand by setting a discharge rod, thereby preventing the sand from entering the sand blaster from the storage box due to the excessively high content of sand ejected in the early stage, which causes the sand in the storage box to lose too much and cause waste. The discharge rod rotates, causing the sand to evenly flow into the connecting pipe from the gap between the discharge rod and the gap tube, and then the sand is transferred to the guide component through the sand spreader, so that the sand content per unit time in the guide component is relatively uniform, thereby ensuring the loss rate of sand. Moreover, the coordinated rotation between the discharge rod and the gap tube can break up the agglomerated sand, so that the sand on the rail surface is uniform, so that the adhesion coefficient between the wheel and rail can be stably increased, thereby increasing the adhesion traction and preventing the wheel from spinning.
[0013] 3. The present invention can control the direction angle of sand spreading by providing a guide component, and can control the direction angle of the guide cylinder by utilizing a lifting component, so that the guide component can control the sand spreading angle when in use. Moreover, since a connecting cylinder is provided in the guide component, the discharge cylinder and the guide cylinder can still be connected when the guide cylinder adjusts the angle. The buffer component provided at the bottom of the guide cylinder can reduce the potential energy of the sand when it comes out. Since the surface of the rail surface is small, the sand will not fall too much when it is sprayed onto the rail surface, so that the sprayed sand falls on the rail surface to the greatest extent, thereby ensuring the utilization rate of the sand.
[0014] 4. The present invention can avoid sand residue in the storage box by providing a stirring component. When the rotating rod rotates, the support rod is driven to rotate through the collar, thereby causing the bottom plate to rotate in the storage box. Since a scratch plate is provided in the bottom plate, the scratch plate will scratch the area at the bottom of the storage box when the bottom plate rotates, thereby causing the sand remaining in the storage box to be discharged from between the discharge rod and the gap tube. In addition, during the rotation of the stirring component, the agglomerated sand can be broken up, thereby reducing the large pieces of sand from moving to the area between the discharge rod and the gap tube, thereby blocking it and preventing it from discharging the sand normally.
[0015] 5. The present invention can control the orientation angle of the guide component by setting a lifting component, and the lifting can be controlled by using the blocking plate in the fixed tube, so that the sand remaining in the guide component after the sand spreading device stops can be preserved and discharged again when the sand spreading device is started next time, avoiding waste. When the lifting component is in use, the movable rod is controlled to move upward by the hydraulic rod, causing the blocking plate to move upward, so that the sand passes from under the blocking plate, thereby reducing the kinetic potential energy of the sand during spraying, reducing the probability of sand falling from the rail surface, and ensuring the utilization rate of the sand.
[0016] 6. The present invention can reduce the kinetic potential energy of sand during discharge by providing a buffer component, thereby ensuring the sand content on the rail surface, so that the sand can increase the adhesion coefficient between the wheel and rail, thereby increasing the adhesion traction and preventing the wheel from idling. When the sand is ejected from the guide component, it will first gather in the guide cylinder. When the gravity of the sand on the baffle plate is greater than the elastic force of the elastic plate, the baffle plate begins to squeeze the elastic plate, so that a gap is generated between the baffle plate and the retention frame, causing the sand to be discharged from the gap onto the rail surface. Since the direction angle of the gap is relatively perpendicular to the rail surface, the utilization rate of the sand is high. BRIEF DESCRIPTION OF THE DRAWINGS

Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.
[0029] Example 1: Use Figures 1-8 A multifunctional overhead wire type industrial and mining motor vehicle 31 according to one embodiment of the present invention is described below.
[0030] like Figures 1-8 As shown, the multifunctional overhead wire type industrial and mining motor vehicle 31 of the present invention includes a vehicle frame 1, a spring bracket 2 is fixedly connected to the top of the vehicle frame 1, a sand spreading device is symmetrically arranged inside the vehicle frame 1, and the outer surface of the sand spreading device 3 is fixedly connected to the inner wall of the vehicle frame 1;
[0031] The frame 1 can increase the adhesion coefficient between the wheel and rail by using the sand spreading device 3 during the movement, so as to increase the adhesion traction and prevent the wheels from spinning;
[0032] The sand spreading device 3 is arranged inside the vehicle frame 1. By setting the sand spreading device 3, the sand spreading angle can be controlled, and the problem of the sand spreading device 3 being difficult to clean after being clogged is reduced by using the rotating rod 40 and the spiral disk 33 in the storage box 32. The sand spreading device 3 includes a storage box 32, the top of the storage box 32 is fixedly connected to the motor 31, the bottom of the motor 31 is rotatably connected to the rotating rod 40, the outer surface of the rotating rod 40 is fixedly connected to the spiral disk 33, the bottom of the storage box 32 is fixedly connected to the connecting pipe 36, the bottom of the connecting pipe 36 is fixedly connected to the sand spreader 37, and the outer surface of the sand spreader 37 is provided with a guide component 35. When the device 3 is in use, the motor 31 is first used to drive the rotating rod 40 to rotate, and then the rotating rod 40 drives the spiral disk 33 to rotate in the storage box 32, and then the agglomerated sand enters the sand spreader 37 through the connecting pipe 36, and is then discharged through the guide component 35. The outer surface of the sand spreader 37 is fixedly connected to the top of the guide component 35, and the storage box 32 is fixedly connected to the fixed block 34 at one end near the guide component 35. The bottom of the rotating rod 40 is fixedly connected to the extension rod 39, and the outer surface of the extension rod 39 is provided with a stirring component 38, and the outer surface of the extension rod 39 is fixedly connected to the top of the stirring component 38. The bottom is fixedly connected with a discharge rod 41. Since the orientation angle of the guide component 35 can be controlled, the sand spreading angle can be controlled. The stirring component 38 on the rotating rod 40 can prevent the residual sand in the storage box 32 from being discharged. A gap tube 42 is provided inside the connecting pipe 36. By providing the discharge rod 41, the uniform flow rate of the sand can be controlled to prevent the sand from entering the sand blaster from the storage box 32. The high content of the early spraying will cause the sand in the storage box 32 to be lost too quickly, resulting in waste. The inner wall of the connecting pipe 36 is fixedly connected to the outer surface of the gap tube 42. The sand is rotated by the discharge rod 41. The sand flows evenly from the gap between the discharge rod 41 and the gap tube 42 into the connecting pipe 36, and is then transferred to the guide component 35 through the sand spreader 37, thereby making the sand content in the guide component 35 more uniform per unit time, thereby ensuring the sand loss rate. The gap tube 42 is located inside the connecting pipe 36. The coordinated rotation between the discharge rod 41 and the gap tube 42 can break up the agglomerated sand, thereby making the sand on the rail surface uniform, so that it can stably increase the adhesion coefficient between the wheel and rail, thereby increasing the adhesion traction and preventing the wheel from spinning. The inner wall of the gap tube 42 is in contact with the outer surface of the discharge rod 41;
[0033] When the sand spreading device 3 is in use, the motor 31 is first used to drive the rotating rod 40 to rotate, and then the rotating rod 40 drives the spiral disk 33 and the stirring component 38 to rotate, stirring the sand in the storage box 32, and then the sand is sprayed out from the sand spreader 37 through the connecting pipe 36, and then the guide component 35 is used to sprinkle the sand onto the rail surface, and the gap tube 42 in the connecting pipe 36 and the discharge rod 41 are used in combination to evenly transfer the sand from the storage box 32 to the sand spreader 37, and the fixed block 34 can be used to control the height of the guide component 35, thereby adjusting the direction angle of the sand when it is sprayed out.
[0034] The guide component 35 includes a discharge pipe 351. By setting the guide component 35, the direction angle of the sand spreading can be controlled. The lifting component 354 can be used to control the direction angle of the guide cylinder 353, so that the guide component 35 can control the sand spreading angle when in use. The outer surface of the discharge pipe 351 is fixedly connected to the connecting cylinder 352. The end of the connecting cylinder 352 away from the discharge pipe 351 is fixedly connected to the guide cylinder 353. Since the connecting cylinder 352 is provided in the guide component 35, the discharge cylinder and the guide cylinder 353 can be adjusted when the angle is adjusted. 353 can still maintain communication, and the buffer component 355 provided at the bottom of the guide cylinder 353 can reduce the potential energy of the sand when it comes out. Since the surface of the rail surface is small, the sand will not fall too much when it is sprayed onto the rail surface, so that the sprayed sand falls on the rail surface to the greatest extent, ensuring the utilization rate of the sand. The end of the guide cylinder 353 away from the connecting cylinder 352 is fixedly connected to the buffer component 355, and the outer surface of the guide cylinder 353 is provided with a lifting component 354, and the outer surface of the guide cylinder 353 is fixedly connected to the inner wall of the lifting component 354;
[0035] When the guide component 35 starts to work, the lifting component 354 cooperates with the fixed block 34 to control the placement angle of the guide cylinder 353, and the connecting cylinder 352 can ensure that the guide cylinder 353 can still maintain communication with the discharge pipe 351 after adjusting the angle, and the buffer component 355 can reduce the impact force of the sand when it is sprayed out, thereby preventing the sand from sliding off the rail surface and causing waste.
[0036] The stirring member 38 includes a collar 381. By providing the stirring member 38, sand can be prevented from remaining in the storage box 32. When the rotating rod 40 rotates, the collar 381 drives the support rod 382 to rotate, thereby causing the bottom plate 383 to rotate in the storage box 32. Since a scratching plate 385 is provided in the bottom plate 383, when the bottom plate 383 rotates, the scratching plate 385 will scratch the area at the bottom of the storage box 32, thereby causing the sand remaining in the storage box 32 to be discharged from the discharge rod 41. The sand is discharged between the discharge rod 41 and the gap tube 42. The outer surface of the collar 381 is symmetrically provided with a support rod 382, and the outer surface of the collar 381 is fixedly connected to the top of the support rod 382.

There are two bottom plates 383, and the bottom plates 383 are symmetrically provided with a support rod 382. The outer surface of the collar 381 is fixedly connected to the top of the support rod 382. The bottom of the support rod 382 is fixedly connected to the bottom of the support rod 383. During the rotation of the stirring member 38, the agglomerated sand can be crushed, thereby reducing the large pieces of sand and moving them to the area between the discharge rod 41 and the gap tube 42, thereby blocking it and preventing it from being discharged normally. The bottom of the bottom plate 383 contacts the inner wall of the storage box 32, and the inner plate 386 is symmetrically arranged inside the bottom plate 383, and the inner wall of the bottom plate 383 is fixedly connected to the outer surface of the inner plate 386.

The bottom of the lifting plate 384 is symmetrically provided with a buffer cylinder 387, and the bottom of the lifting plate 384 is fixed to the top of the buffer cylinder 387. The lifting plate 384 is connected with a rotating rod 389 inside, and the inner wall of the lifting plate 384 is fixedly connected to the two ends of the rotating rod 389, the outer surface of the rotating rod 389 is provided with a scratch plate 385, and the outer surface of the rotating rod 389 is rotatably connected to the top of the scratch plate 385, and the outer surface of the scratch plate 385 is symmetrically provided with a fixing rod 391, and the outer surface of the scratch plate 385 is fixedly connected to the opposite side of the fixing rod 391, and the end of the fixing rod 391 away from the scratch plate 385 is fixedly connected to the flexible plate 390;
[0037] When the stirring component 38 is in use, the ring 381 is first rotated by means of the rotating rod 40, and then the sand in the storage box 32 is cleaned by means of the scratching plate 385 provided in the bottom plate 383. Since the height of the bottom of the storage box 32 is different, the scratching plate 385 always keeps in contact with the bottom of the storage tube with the help of the buffer tube 387, thereby cleaning its surface.
[0038] Example 2: Use Figures 1-8 A multifunctional overhead wire type industrial and mining motor vehicle 31 according to one embodiment of the present invention is described below.
[0039] like Figures 1-8The lifting mechanism 354 is a kind of multifunctional overhead mining motor vehicle 31 of the present invention, based on the first embodiment, the lifting component 354 includes a lifting rod 3541. By setting the lifting component 354, the direction angle of the guide component 35 can be controlled, and the blocking plate 3543 in the fixed tube 3542 can be used to control the lifting and lowering, so that the sand remaining in the guide component 35 after the sand spreading device 3 stops can be preserved and discharged again when the sand spreading device 3 is started next time, thereby avoiding waste. The bottom of the lifting rod 3541 is rotatably connected to the bearing ring 3547, and the bottom of the bearing ring 3547 is symmetrically provided with a limit plate 3546, and the bottom of the bearing ring 3547 is fixedly connected to the inner wall of the limit plate 3546. When the lifting component 354 is in use, the movable rod 3557 is controlled to move upward by the hydraulic rod 3548, causing the blocking plate 3543 to move upward, so that the sand passes through the bottom of the blocking plate 3543, thereby reducing the dynamic potential energy of the sand during spraying, reducing the probability of sand falling from the rail surface, and ensuring the utilization of the sand. The outer surface of the limit plate 3546 is fixedly connected to the fixed tube 3542, the interior of the fixed tube 3542 is provided with a blocking plate 3543, and the inner wall of the fixed tube 3542 is in contact with the bottom of the blocking plate 3543, the top of the blocking plate 3543 is fixedly connected to the lifting rod 3545, the top of the lifting rod 3545 is fixedly connected to the placement plate 3558, the top of the placement plate 3558 is fixedly connected to the movable rod 3557, the top of the movable rod 3557 is fixedly connected to the hydraulic rod 3548, and the movable rod 3545 is fixedly connected to the hydraulic rod 3548. A fixing bracket 3544 is provided on the outer surface of 557, the inner wall of the fixing bracket 3544 contacts the outer surface of the movable rod 3557, a guide block 3549 is provided on the outer surface of the movable rod 3557, and the outer surface of the movable rod 3557 is slidably connected to the inner wall of the guide block 3549, a positioning rod 3559 is symmetrically provided on the outer surface of the guide block 3549, and the outer surface of the guide block 3549 is fixedly connected to the inner wall of the positioning rod 3559, and a return spring 3550 is fixedly connected to the bottom of the guide block 3549;
[0040] When the lifting component 354 starts to be used, the height of the fixed tube 3542 is first controlled by means of the lifting rod 3541 and the fixed block 34, and then the movable rod 3557 is controlled to be raised and lowered by the hydraulic rod 3548, so that the position of the blocking plate 3543 in the fixed tube 3542 changes. When the sand spreading device 3 is working, the blocking plate 3543 moves upward, causing a gap to be formed between the inner wall of the fixed tube 3542 and the bottom of the blocking plate 3543, thereby allowing sand to be discharged from the gap. Due to the obstruction of the blocking plate 3543, the dynamic potential energy of the sand when it is sprayed out is small, and it will not fall from the rail surface.
[0041] The buffer component 355 includes a retention frame 3551. By setting the buffer component 355, the dynamic potential energy of the sand during discharge can be reduced, thereby ensuring the sand content on the rail surface, so that the sand can increase the adhesion coefficient between the wheel and the rail, thereby increasing the adhesion traction and preventing the wheel from idling. The top of the retention frame 3551 is symmetrically provided with a positioning plate 3556, and the top of the retention frame 3551 is fixedly connected to the bottom of the positioning plate 3556. The interior of the positioning plate 3556 is provided with an elastic plate 3553, and the inner wall of the positioning plate 3556 is fixedly connected to the top of the elastic plate 3553. The bottom of the elastic plate 3553 is fixedly connected to a shielding plate 3555. The shielding plate An inner rod 3554 is provided inside 3555. When sand is ejected from the guide component 35, it first accumulates in the guide cylinder 353. When the gravity of the sand on the shielding plate 3555 is greater than the elastic force of the elastic plate 3553, the shielding plate 3555 begins to squeeze the elastic plate 3553, so that a gap is generated between the shielding plate 3555 and the retention frame 3551, causing the sand to be discharged from the gap onto the rail surface. Since the direction angle of the gap is relatively perpendicular to the rail surface, the utilization rate of the sand is high. The inner wall of the shielding plate 3555 is rotatably connected to the outer surface of the inner rod 3554, and the top of the shielding plate 3555 is fixedly connected to the top plate 3552.
[0042] When the buffer component 355 is in use, the elastic plate 3553 and the shielding plate 3555 are first used to block the retention frame 3551. When the sand in the retention frame 3551 accumulates to a certain extent, the shielding plate 3555 is subjected to too much gravity of the sand, causing the shielding plate 3555 to squeeze the elastic plate 3553, causing the elastic plate 3553 to bend and shrink, and then causing a gap to form between the retention frame 3551 and the shielding plate 3555, thereby causing the sand to be discharged from the gap.
