Description

Technical Field

[0001] The present invention relates to the technical field of rail transportation equipment, in particular to a locomotive track sand spreading device. Background Art

[0002] Railway transportation relies on the traction and braking adhesion friction generated by the interaction between wheels and rails to enable train operation. With the construction of high-speed railways, the traction load of electric locomotives has increased significantly, making improving locomotive adhesion performance a crucial issue. Therefore, to ensure the normal operation of rail vehicles, sanding operations are required as needed during travel to increase the friction between the rails and the wheels. This sanding operation is usually performed by a sanding device.

[0003] The existing sand spreading device can basically meet the use requirements of the locomotive, but the sand spreading pipe at the bottom of the sand spreading device under the existing technology is connected to the inside of the sand storage box. The water vapor in the air can easily enter the sand storage box through the sand discharge pipe. The sand is easy to clump when it gets damp, and the agglomerated sand is easy to clog the sand discharge pipe, thereby hindering the discharge of the sand. Summary of the Invention

[0013] Furthermore, the reset mechanism also includes several connecting blocks 2 fixedly connected to the inner wall of the sand leakage tube, the end of the connecting block 2 away from the inner wall of the sand leakage tube is fixedly connected to a fixed rod, the end of the fixed rod away from the connecting block 2 is slidably connected to a rotating ring 2, the rotating ring 2 is rotatably connected to the connecting rod 1, and the end of the fixed rod away from the rotating ring 2 is provided with a reset spring.

[0014] Furthermore, the reset mechanism also includes a movable frame slidably connected to the bottom of the output rotating shaft, the end of the movable frame away from the output rotating shaft is slidably connected to the fixed rod, the top of the movable frame is fixedly connected with a rotating sleeve, the rotating sleeve is slidably connected to the output rotating shaft, a limiting groove is provided at the end of the rotating sleeve away from the movable frame, a movable ring is rotatably connected inside the limiting groove, the side wall of the movable ring is rotatably connected to several connecting rods 2, and the end of the connecting rod 2 away from the moving ring is rotatably connected to the toggle rod.

[0015] The present invention has the following beneficial effects:

[0016] (1) According to the present invention, when the locomotive track sand spreading device is used, sand can first be put into the interior of the sand storage box by adding material, and the sand and gravel are guided to the bottom plate through the sand guide inclined plate. When the locomotive starts to start, the DC motor at the bottom of the protective cover is first started, and the output end of the DC motor drives the output shaft to rotate. The rotation of the output shaft drives several sliding frames on the fixed block to rotate. The rotation of the sliding frame drives the toggle rod to rotate. At this time, the rotation of the toggle rod is squeezed with the driving plate. When the toggle rod and the driving plate are squeezed, the toggle rod toggles the arc-shaped blocking piece at one end of the driving plate to squeeze the squeezing spring along the arc-shaped rod. At this time, the arc-shaped blocking piece is separated from the sand inlet hole on the inner wall of the sand discharge tube. Such a setting is conducive to opening the sand inlet hole on the sand discharge tube. At this time, the sand enters the interior of the sand discharge tube through the sand inlet hole, thereby ensuring that when the device is used, the sand can be controlled to enter the interior of the sand discharge tube through the sand inlet hole and be discharged to the locomotive track through the sand discharge pipe at the bottom of the sand discharge tube.

[0017] (2) According to the present invention, when the device is not in use, the extrusion spring squeezes the arc-shaped blocking piece to move along the arc-shaped rod toward one end close to the sand inlet hole under the elastic force of the extrusion spring. This arrangement is conducive to the arc-shaped blocking piece blocking the sand inlet hole, isolating the sand material inside the sand storage box from contact with the outside air, thereby preventing external moisture from entering the interior of the sand storage box from the bottom of the sand outlet pipe, preventing the sand material from getting damp and agglomerated, and thus preventing the agglomerated sand material from clogging the inside of the sand outlet pipe, thereby ensuring that the sand material in the device is discharged smoothly; in addition, the sand material can be screened through the sand outlet tube to prevent large pieces of sand material from clogging the sand outlet pipe.

[0018] (3) The present invention sets a breaking mechanism. When the toggle rod and the driving plate are squeezed, the toggle rod toggle the arc-shaped blocking piece at one end of the driving plate to squeeze the squeezing spring along the arc-shaped rod. The arc-shaped blocking piece drives the rotating column at one end of the connecting rod to move along the outer wall of the sand discharge tube. At this time, the rotating column drives the gear to move along the gear ring. Under the meshing action of the gear ring, the gear drives several breaking rods on the rotating column to rotate. This setting is conducive to the rapid rotation of the breaking rod to break up the agglomerated sand materials near the sand inlet hole, thereby accelerating the rate at which the sand materials pass through the sand inlet hole into the inside of the sand discharge tube. On the other hand, it is conducive to quickly stirring the sand materials near the sand inlet hole to avoid the sand materials clogging the sand inlet hole, thereby ensuring the stable operation of the device.

[0019] (4) The present invention sets a reset mechanism. When the toggle rod and the driving plate are squeezed, the toggle rod toggle the arc-shaped blocking piece at one end of the driving plate to squeeze the squeezing spring along the arc rod. The arc-shaped blocking piece drives the rotating ring 1 at one end of the bottom rotating rod to move. The movement of the rotating ring 1 drives the rotating ring 2 at one end of the connecting rod 1 to slide downward along the fixed rod. The fixed rod slides downward and drives the moving frame to squeeze the reset spring downward. At this time, the moving frame drives the moving ring inside the limiting groove at one end of the rotating sleeve to move downward. The moving ring moves downward and drives the toggle rod at one end of the connecting rod 2 to move along the sliding frame toward one end of the fixed block. When the toggle rod is out of contact with the driving plate, the squeezing spring drives the arc-shaped blocking piece to reset. This setting is conducive to the arc-shaped blocking piece to move back and forth, thereby ensuring that the sand material continuously enters the sand outlet tube from the sand inlet hole.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The sand output control mechanism 2 includes a sand output cylinder 201 fixedly connected to the top of the base plate 13. The end of the sand output cylinder 201 away from the base plate 13 is fixedly connected to a protective cover 202. The bottom of the protective cover 202 is fixedly connected to a DC motor 203. The output end of the DC motor 203 is fixedly connected to an output shaft 204. The end of the output shaft 204 close to the DC motor 203 is fixedly connected to a fixed block 205.

[0037] The sand output control mechanism 2 also includes a plurality of sliding frames 206 fixedly connected to the side wall of the fixed block 205, and the internal sliding connection of the sliding frame 206 is connected to the toggle rod 207, and the side wall of the sand output tube 201 is provided with a plurality of groups of sand inlet holes 208. The function of this component is that when the locomotive track sand spreading device is used, the sand material can first be put into the interior of the sand storage box 1 through the feeding 11, and the sand and gravel are guided to the bottom plate 13 through the sand guide inclined plate 12. When the locomotive starts to start, the DC motor 203 at the bottom of the protective cover 202 is first started, and the output end of the DC motor 203 drives the output shaft 204 to rotate. The rotation of the output shaft 204 drives the plurality of sliding frames 206 on the fixed block 205 to rotate, and the rotation of the sliding frame 206 drives the toggle rod 207 to rotate. When the movable rod 207 rotates, the toggle rod 207 rotates and is squeezed with the driving plate 212. When the toggle rod 207 is squeezed with the driving plate 212, the toggle rod 207 toggles the arc-shaped blocking piece 211 at one end of the driving plate 212 to squeeze the squeezing spring 213 along the arc rod 210. At this time, the arc-shaped blocking piece 211 is disengaged from the sand inlet hole 208 on the inner wall of the sand discharge tube 201. This arrangement is conducive to opening the sand inlet hole 208 on the sand discharge tube 201. At this time, the sand enters the interior of the sand discharge tube 201 through the sand inlet hole 208, thereby ensuring that when the device is used, the sand can be controlled to enter the interior of the sand discharge tube 201 through the sand inlet hole 208 and be discharged onto the locomotive track through the sand discharge pipe 15 at the bottom of the sand leakage tube 14.

[0038] The sand output control mechanism 2 also includes a plurality of connecting blocks 209 fixedly connected to the inner wall of the sand output cylinder 201. The end of the connecting block 209 away from the inner wall of the sand output cylinder 201 is fixedly connected to an arc rod 210. The middle part of the arc rod 210 is slidably connected to an arc blocking piece 211. The arc blocking piece 211 fits with the sand inlet hole 208 on the inner wall of the sand output cylinder 201. The side of the arc blocking piece 211 away from the inner wall of the sand output cylinder 201 is fixedly connected to a driving plate 212. The driving plate 212 fits with the sliding frame 206. The function of this component is to squeeze the spring 213 when the device is not in use. Under the action of force, the extrusion spring 213 squeezes the arc-shaped blocking piece 211 and moves along the arc rod 210 toward one end close to the sand inlet hole 208. This arrangement is conducive to the arc-shaped blocking piece 211 blocking the sand inlet hole 208, isolating the sand inside the sand storage box 1 from contact with the outside air, thereby preventing external moisture from entering the interior of the sand storage box 1 from the bottom of the sand outlet pipe 15, preventing the sand from getting damp and agglomerating, and thus preventing the agglomerated sand from clogging the inside of the sand outlet pipe 15, ensuring that the sand in the device is discharged smoothly; in addition, the sand can be screened through the sand outlet cylinder 201 to prevent large pieces of sand from clogging the sand outlet pipe 15.

The crushing mechanism 3 includes a gear ring 301 fixedly connected to the upper and lower outer walls of the sand discharge cylinder 201 . A connecting rod 302 is fixedly connected to the top of the arc-shaped blocking piece 211 .

[0040] Example 2 is distinguished from Example 1 in that: Figures 1-10 As shown, the crushing mechanism 3 also includes a rotating column 303 rotatably connected to the end of the connecting rod 302 away from the arc-shaped blocking piece 211, and both ends of the rotating column 303 are fixedly connected to a gear 304, which meshes with the gear ring 301, and the side wall of the rotating column 303 is fixedly connected to a plurality of crushing rods 305, which are close to the outer wall of the sand discharge tube 201. The function of this component is to set the crushing mechanism 3. When the toggle rod 207 is squeezed with the driving plate 212, the toggle rod 207 toggles the arc-shaped blocking piece 211 at one end of the driving plate 212 along the arc rod 210 to squeeze the extrusion spring 213, and the arc-shaped blocking piece 211 drives The rotating column 303 at one end of the connecting rod 302 moves along the outer wall of the sand discharge tube 201. At this time, the rotating column 303 drives the gear 304 to move along the gear ring 301. Under the meshing action of the gear ring 301, the gear 304 drives several breaking rods 305 on the rotating column 303 to rotate. On the one hand, this arrangement is conducive to the rotation of the breaking rods 305 to quickly break up the agglomerated sand materials near the sand inlet hole 208, thereby accelerating the rate at which the sand materials pass through the sand inlet hole 208 and enter the sand discharge tube 201. On the other hand, it is conducive to quickly stirring the sand materials near the sand inlet hole 208 to avoid the sand materials clogging the sand inlet hole 208, thereby ensuring the stable operation of the device.

[0041] A reset mechanism 4 is provided directly below the arc-shaped blocking piece 211. The reset mechanism 4 includes a rotating rod 401 rotatably connected to the bottom of the arc-shaped blocking piece 211. The end of the rotating rod 401 away from the arc-shaped blocking piece 211 is rotatably connected to a rotating ring 1 402.

The end of the fixed rod 405 away from the connecting block 404 is slidably connected to a rotating ring 2 406. The rotating ring 2 406 is rotatably connected to the connecting rod 1 403. The end of the fixed rod 405 away from the rotating ring 2 406 is sleeved with a reset spring 407.

[0043] The reset mechanism 4 also includes a movable frame 408 slidably connected to the bottom of the output rotating shaft 204, and the movable frame 408 is slidably connected to the fixed rod 405 at one end away from the output rotating shaft 204. The top of the movable frame 408 is fixedly connected with a rotating sleeve 409, and the rotating sleeve 409 is slidably connected to the output rotating shaft 204. A limiting groove 410 is provided at one end of the rotating sleeve 409 away from the movable frame 408. A movable ring 411 is rotatably connected inside the limiting groove 410, and a side wall of the movable ring 411 is rotatably connected to a plurality of connecting rods 412.

When the toggle rod 207 is squeezed with the driving plate 212, the toggle rod 207 toggles the arc-shaped blocking piece 211 at one end of the driving plate 212 to squeeze the extrusion spring 213 along the arc rod 210. The arc-shaped blocking piece 211 drives the rotating ring 1 402 at one end of the bottom rotating rod 401 to move, and the rotating ring 1 402 moves and drives the rotating ring 2 406 at one end of the connecting rod 1 403 to slide downward along the fixed rod 405. The fixed rod 405 slides downward and drives the moving frame 408 to squeeze the return spring 407 downward. At this time, the moving frame 408 drives the moving ring 411 inside the limiting groove 410 at one end of the rotating sleeve 409 to move downward. The moving ring 411 moves downward and drives the toggle rod 207 at one end of the connecting rod 2 412 to move along the sliding frame 206 toward one end close to the fixed block 205. When the toggle rod 207 is out of contact with the driving plate 212, the extrusion spring 213 drives the arc-shaped blocking piece 211 to reset. This arrangement is conducive to making the arc-shaped blocking piece 211 move back and forth, thereby ensuring that the sand material continuously enters the sand outlet tube 201 from the sand inlet hole 208.

[0044] A specific application of this embodiment is:

[0045] When the locomotive track sand spreading device is used, sand can first be put into the interior of the sand storage box 1 through the feeding 11, and the sand and gravel are guided to the bottom plate 13 through the sand guide inclined plate 12. When the locomotive starts to start, the DC motor 203 at the bottom of the protective cover 202 is first started, and the output end of the DC motor 203 drives the output shaft 204 to rotate. The rotation of the output shaft 204 drives several sliding racks 206 on the fixed block 205 to rotate, and the rotation of the sliding rack 206 drives the toggle rod 207 to rotate. At this time, the rotation of the toggle rod 207 and the driving plate 212 are squeezed. When the toggle rod 207 and the driving plate 212 are squeezed, the toggle rod 207 toggles the arc-shaped blocking piece 211 at one end of the driving plate 212 to squeeze the squeezing spring 213 along the arc-shaped rod 210. At this time, the arc-shaped blocking piece 211 is disengaged from the sand inlet hole 208 on the inner wall of the sand discharge tube 201. This arrangement is conducive to opening the sand inlet hole 208 on the sand discharge tube 201. When the sand material is discharged from the sand discharge tube 15, the sand material is prevented from entering the sand discharge tube 15 and the sand material is discharged to the sand discharge tube 15.

[0046] By setting the crushing mechanism 3, when the toggle rod 207 is squeezed with the driving plate 212, the toggle rod 207 toggles the arc-shaped blocking piece 211 at one end of the driving plate 212 to squeeze the extrusion spring 213 along the arc-shaped rod 210, and the arc-shaped blocking piece 211 drives the rotating column 303 at one end of the connecting rod 302 to move along the outer wall of the sand discharge tube 201. At this time, the rotating column 303 drives the gear 304 to move along the gear ring 301. Under the meshing action of the gear ring 301, the gear 304 drives the rotating column 303 to move along the outer wall of the sand discharge tube 201. 3 on the plurality of breaking rods 305 rotate, such a setting is conducive to the breaking rod 305 rotating quickly to break up the agglomerated sand material near the sand inlet hole 208, thereby accelerating the rate at which the sand material passes through the sand inlet hole 208 into the sand outlet tube 201, and on the other hand is conducive to quickly stirring the sand material near the sand inlet hole 208, avoiding the sand material from clogging the sand inlet hole 208, and ensuring the stable operation of the device; by setting the reset mechanism 4, when the toggle rod 207 and the driving plate 212 are squeezed The toggle rod 207 toggles the arc-shaped blocking piece 211 at one end of the driving plate 212 along the arc-shaped rod 210 to squeeze the squeezing spring 213. The arc-shaped blocking piece 211 drives the rotating ring 1 402 at one end of the bottom rotating rod 401 to move. The rotating ring 1 402 moves and drives the rotating ring 2 406 at one end of the connecting rod 1 403 to slide downward along the fixed rod 405. The fixed rod 405 slides downward and drives the moving frame 408 to squeeze the return spring 407 downward. At this time, the moving frame 408 drives the rotating sleeve 409 to move. The movable ring 411 inside the end limit groove 410 moves downward, and the movable ring 411 moves downward to drive the toggle rod 207 at one end of the connecting rod 212 to move along the sliding frame 206 toward the end close to the fixed block 205. When the toggle rod 207 is out of contact with the driving plate 212, the extrusion spring 213 drives the arc-shaped blocking piece 211 to reset. This arrangement is conducive to the reciprocating movement of the arc-shaped blocking piece 211, thereby ensuring that the sand material continuously enters the sand outlet tube 201 from the sand inlet hole 208.
