Description

[0002] As an important infrastructure of transportation, railways carry a large number of passenger and freight transportation tasks around the world. Railway sleepers are an important part of railway tracks. As a key component of railway tracks, railway sleepers play a vital role. They directly bear the pressure from the rails and evenly distribute the pressure to the roadbed foundation, thereby ensuring the stability and smoothness of the railway track. In the production process of sleepers, stacking operations are a key link.

[0003] However, most of the existing sleeper stackers cannot automatically reciprocate and clean the clamping plate during its movement, resulting in a large amount of impurities and foreign matter on the surface of the clamping plate, affecting the tightness and firmness of the clamping sleeper, which may endanger the safe operation of the equipment.

[0004] At the same time, most of the existing sleeper stackers are not convenient for cleaning the surface of the sleepers, so the surface cleanliness of the sleeper products is low, which easily affects the tightness of the sleeper stacking, further causing the sleepers to slide or misalign during stacking and transportation, affecting the stability of the sleeper products when stacked.

The dust generated in the process of cleaning the clamping and conveying mechanism 2 by the cleaning mechanism 3 is absorbed by the dust suction and blowing mechanism 4. During the upward resetting of the clamping and conveying mechanism 2, the dust suction and blowing mechanism 4 is driven to blow air toward the surface of the sleeper.

[0049] When in use, the sleeper product can be clamped by starting the clamping and conveying mechanism 2, and the clamped sleeper product can be stacked on the surface of the second roller conveyor 102, thereby realizing the automatic stacking of the sleeper product. At the same time, during the downward movement of the clamping and conveying mechanism 2, the cleaning mechanism 3 can clean the clamping plate 208, and at the same time, the dust suction and blowing mechanism 4 can be driven to absorb some of the dust and impurities generated during cleaning. During the upward movement of the clamping and conveying mechanism 2, the upper surface of the sleeper during the clamping process can be effectively cleaned, thereby improving the stability of multiple sleepers when stacked.

[0050] like Figure 5 104, the product transfer mechanism 1 comprises a first roller conveyor 101 and a second roller conveyor 102, the first roller conveyor 101 is located in the middle of the upper end of the second roller conveyor 102, the upper surface of the first roller conveyor 101 is fixedly connected to an assembly rack 103, a pallet 105 is provided at the upper end of the second roller conveyor 102, a stacked sleeper 106 is stacked at the upper end of the pallet 105 on one side, a single sleeper 107 is provided at the upper part of the rear end of the first roller conveyor 101, and the first roller conveyor 101 near the front end is provided with a plurality of rails. A support plate 104 is fixedly connected in the middle, and the lower surface of the support plate 104 is fixedly connected to the front and rear ends of the middle part of the upper surface of the second roller conveyor 102, wherein a single sleeper 107 can be transmitted in sequence through the first roller conveyor 101, and a pallet 105 can be transmitted in sequence through the second roller conveyor 102 to move the pallet 105 to the stacking position, and the stacked sleepers 106 can also be transmitted to the tail end of the second roller conveyor 102. At this time, the staff can use a forklift to transfer the sleeper products in sequence.

[0051] like Figure 6 and Figure 7The clamping and conveying mechanism 2 includes a servo motor 201 and a clamping frame 206. The servo motor 201 is fixedly connected to the upper part of the front end outer wall of the assembly frame 103. The output end of the servo motor 201 is fixedly connected to a one-way screw rod 202. The rod body of the one-way screw rod 202 is sleeved with a one-way slider 203. The middle part of the upper surface of the fixed plate 204 is fixedly connected to the lower surface of the one-way slider 203. The two sides of the upper surface of the fixed plate 204 are fixedly connected to a long electric telescopic rod 205. The output end of the long electric telescopic rod 205 is fixedly connected to the clamping frame 206. The clamping frame 206 is far A short electric telescopic rod 207 is fixedly connected to the middle of one side of the fixed plate 204, and a clamping plate 208 is fixedly connected to the output end of the short electric telescopic rod 207. The two sides of the upper surface of the fixed plate 204 are fixedly connected to the limiting plates 209. The two sides of the inner top surface of the assembly frame 103 are provided with limiting grooves 108. The limiting plates 209 are slidably connected inside the limiting grooves 108. Specifically, in the process of stacking the sleepers, the one-way screw rod 202 can be rotated by starting the servo motor 201. At this time, the one-way slider 203 drives the fixed plate 204 and the clamping frame 206. The clamping frame 206 is moved to the designated position, and the long electric telescopic rod 205 is started to make the clamping frame 206 and the short electric telescopic rod 207 move toward the direction of the single rail sleeper 107. When the clamping frame 206 moves to the designated position, the long electric telescopic rod 205 is stopped and the short electric telescopic rod 207 is started. At this time, the clamping plate 208 moves toward the single rail sleeper 107 under the action of the short electric telescopic rod 207 and clamps and fixes the single rail sleeper 107. At this time, the servo motor 201 is started first to make the one-way slider 203 drive the clamping frame 206 Move a certain distance in the direction of the second roller conveyor 102, and then start the long electric telescopic rod 205 to reset the clamping frame 206. At this time, the single sleeper 107 also moves upward, and then the servo motor 201 can make the single sleeper 107 in the clamping process move synchronously in the direction of the second roller conveyor 102. When it moves to the specified position, the single sleeper 107 can be stacked on the surface of the pallet 105 in sequence through the alternating cooperation of the long electric telescopic rod 205 and the short electric telescopic rod 207, thereby realizing the stacking of the sleeper products in sequence.

[0052] like Figure 8 and Fig. 9The cleaning mechanism 3 includes a long rotating rod 301 and an active tooth plate 302. The long rotating rod 301 is rotatably connected to the rear end of the upper surface of the clamping frame 206. The two active tooth plates 302 are respectively fixedly connected to the two sides of the rear end of the inner top surface of the assembly frame 103. The outer walls of both sides of the long rotating rod 301 are fixedly connected with driven gear cylinders 303. The driven gear cylinders 303 and the active tooth plates 302 are meshed with each other. Both sides of the upper surface of the clamping frame 206 are rotatably connected with bidirectional reciprocating screws 304. The middle part of the upper surface of the clamping frame 206 is rotatably connected with a short rotating rod 305. The outer wall in the middle of the long rotating rod 301 is fixedly connected to the first bevel gear 306. The outer wall of the rear end of the short rotating rod 305 is fixedly connected to the second bevel gear 307. The outer wall in the middle of the bidirectional reciprocating screw 304 and the short rotating rod 305 are fixedly connected to the second bevel gear 307. The outer wall of the front end of the rod 305 is fixedly connected to a transmission wheel 308, and the outer wall of the transmission wheel 308 is sleeved with a toothed belt 309. Reciprocating sliders 310 are sleeved on both sides of the rod body of the bidirectional reciprocating screw 304. The end of the reciprocating slider 310 away from the short rotating rod 305 is fixedly connected to a connecting rod 311, and the end of the connecting rod 311 away from the reciprocating slider 310 is rotatably connected to a transmission rod 312. The outer wall of the lower end of the transmission rod 312 is sleeved with a cleaning sleeve 314, and the cleaning sleeve 314 cleans the clamping plate 208 during the reciprocating movement. The edges of the upper surface of the clamping frame 206 on both sides are fixedly connected to an intermediate gear rack 315, and the outer wall of the upper end of the transmission rod 312 is fixedly connected to an intermediate gear 313, and the intermediate gear 313 and the intermediate gear rack 315 are fixedly connected. The long rotating rod 301 and the bidirectional reciprocating screw 304 are both located at the lower end of the fixed plate 204, and the first bevel gear 306 is meshed with the second bevel gear 307. Specifically, in the process of stacking the sleepers, the fixed plate 204 and the clamping frame 206 can be moved to the specified position by starting the servo motor 201. At this time, the driven gear cylinder 303 will move to the upper end of the active gear plate 302, and then the fixed plate 204 and the clamping frame 206 can be moved downward by starting the long electric telescopic rod 205. The driven gear cylinder 303 will mesh with the active gear plate 302. At this time, the long rotating rod 301 will drive the first bevel gear 306 to rotate, and mesh with the second bevel gear 307 to rotate the short rotating rod 305. At this time, the two-way reciprocating screw 304 starts to rotate under the action of the transmission wheel 308. At this time, the reciprocating slider 310 starts to reciprocate on the rod body of the two-way reciprocating screw 304, and at the same time drives the connecting rod 311, the transmission rod 312 and the intermediate gear 313 to reciprocate. At this time, the intermediate gear 313 will mesh with the intermediate gear rack 315 during the reciprocating movement, so that the transmission rod 312 drives the cleaning sleeve 314 to start rotating. At this time, the cleaning sleeve 314 in the moving and rotating process starts to wipe the surface of the clamping plate 208. When the clamping frame 206 reaches the position to be clamped of the sleeper product, the reciprocating slider 310 drives the cleaning sleeve 314 to move to the original position on the rod body of the two-way reciprocating screw 304. When the clamping plate 208 clamps the sleeper product,Restart the servo motor 201 to make the one-way slider 203 drive the clamping frame 206 to move a certain distance toward the direction of the second roller conveyor 102, so that the driven gear cylinder 303 does not mesh with the active gear plate 302. Therefore, the clamping plate 208 is wiped and cleaned every time it is used, which can effectively reduce foreign matter and impurities adhering to the surface of the clamping plate 208, improve the stability of the clamping plate 208 when clamping the sleeper, and effectively reduce the possibility of the sleeper falling off.

The front end and the rear end of both sides of the clamping frame 206 are respectively fixedly connected with a ventilation box 412, and the lower end of the ventilation box 412 is through-connected with a plurality of ventilation heads 413, and the lower end of the outer wall of one side of the negative pressure box 401 is fixedly connected with a filter box 414, and the end of the lower part of the negative pressure box 401 away from the middle of the fixed plate 204 is through-connected with a long connecting pipe 415, and the long connecting pipe 415 The upper part is connected with a first short connecting pipe 416, the lower end of the first short connecting pipe 416 is connected with the upper end of the filter box 414, the lower part of the long connecting pipe 415 close to the tube body is connected with a second short connecting pipe 418, the end of the second short connecting pipe 418 away from the long connecting pipe 415 is connected with the lower end of the filter box 414, the lower end of the long connecting pipe 415 is fixedly connected with a bellows 420, the lower end of the bellows 420 is connected with the ventilation box 412, the front end and the rear end of one side of the inner bottom surface of the negative pressure box 401 are fixedly connected with the guide rod 404, the sealing plate 402 is slidably connected to the outer wall of the guide rod 404, the middle part of the first short connecting pipe 416 is fixedly connected with a first one-way valve 417, the middle part of the long connecting pipe 415 is fixedly connected with a second one-way valve 419 Specifically, in the process of stacking the sleepers, the fixing plate 204 and the clamping frame 206 can be moved to the position of the sleepers to be clamped by starting the servo motor 201, and then the clamping frame 206 can be moved downward by starting the long electric telescopic rod 205. At this time, the bottom plate 410 will drive the L-shaped connecting frame 411, the guide sleeve 408 and the intermediate tooth plate 409 to move downward. At this time, the intermediate tooth plate 409 will mesh with the intermediate gear cylinder 405, and the positioning tooth plate 403 will drive the sealing plate 402 to move upward. At this time, the interior of the negative pressure box 401 will generate negative pressure due to the upward movement of the sealing plate 402. At this time, the second one-way valve 419 is in a closed state, and the first one-way valve 417 is in an open state. At this time, under the action of the negative pressure inside the negative pressure box 401,The ventilation box 412 starts to inhale air through the ventilation head 413, and at the same time, the cleaning sleeve 314 rotates and reciprocates on the outer wall of the clamping plate 208. At this time, the dust generated in the process of the cleaning sleeve 314 cleaning the clamping plate 208 will be adsorbed by the ventilation head 413, thereby reducing the phenomenon of dust impurities adhering to the surface of the clamping plate 208 again. At the same time, the gas inhaled inside the ventilation box 412 will pass through the bellows 420 and the second short connecting pipe 418 to enter the interior of the filter box 414. The filter net inside the filter box 414 will filter the inhaled gas, and then enter the interior of the negative pressure box 401 through the first short connecting pipe 416 and the long connecting pipe 415. When the clamping plate 208 clamps the sleeper product, the servo motor 201 is started to make the one-way slider 203 drive the clamping frame 206 toward The second roller conveyor 102 moves a certain distance in the direction of the second roller conveyor 102 so that the driven gear cylinder 303 does not mesh with the active gear plate 302. When the long electric telescopic rod 205 is started to make the clamping frame 206 return to its original position, the sealing plate 402 is located at the upper end of the negative pressure box 401, and the bottom plate 410 drives the L-shaped connecting frame 411, the guide sleeve 408 and the middle gear plate 409 to move upward. At this time, the middle gear plate 409 will mesh with the middle gear cylinder 405 and make the positioning gear plate 403 drive the sealing plate 402 to move downward inside the negative pressure box 401. At this time, the gas inside the negative pressure box 401 is pressurized. At this time, the pressurized gas will enter the interior of the ventilation box 412 through the long connecting pipe 415 and the bellows 420, and then be sprayed to the sleeper product by multiple ventilation heads 413. At this time, some debris and dust on the surface of the sleeper product will be blown away and blown off, thereby improving the cleanliness of the surface of the sleeper product and making the stacked sleepers more tightly connected, so that the sleeper products are not prone to sliding or dislocation during stacking and transportation, thereby improving the stability of the stacking. Among them, the long electric telescopic rod 205 is controlled to make the clamping frame 206 move up and down reciprocatingly to realize the transportation of the sleeper product. First, the cleaning mechanism 3 can be driven to automatically reciprocate and clean the clamping plate 208 during the downward movement, which effectively reduces the impurities and foreign matter on the surface of the clamping plate 208, thereby making the clamping plate 208 fit more closely when clamping the sleeper product, thereby improving the firmness of the clamping plate 208 when clamping the sleeper product, and ensuring the safe operation of the equipment. Secondly, it can automatically absorb part of the dust generated during the cleaning process of the cleaning mechanism 3, thereby reducing the possibility of foreign matter and dust generated during the cleaning process adhering to the surface of the clamping plate 208 again, further ensuring the neatness of the clamping plate 208. Thirdly, the cleaning operation of the cleaning mechanism 3 can be automatically performed in the process of the clamping frame 206 approaching the sleeper product. At the same time, the disengagement mechanism of the driven gear cylinder 303 and the active gear plate 302 is simple and effective, which improves the automation degree of the equipment and reduces unnecessary energy waste and operation steps. Fourthly, the dust suction and blowing mechanism 4 can assist in dust suction during the descent of the clamping frame 206, and can blow air to the surface of the sleeper product during the ascent of the clamping frame 206, thereby improving the cleanliness of the upper surface of the sleeper product.The stacked sleepers are more tightly connected, so that the sleeper products are not prone to sliding or dislocation during stacking and transportation, and the stacking stability is improved. Fifth, the cleaning of the clamping plate 208 and the sleeper products does not require human intervention, the cleaning frequency of the clamping plate 208 is high, and there is no need to add corresponding electrical components, thereby saving the use cost of the device.

[0054] Specifically, the working principle of the high-efficiency stacker for railway sleepers is as follows: during the process of stacking sleepers, the fixed plate 204 and the clamping frame 206 can be moved to the specified position by starting the servo motor 201, and the driven gear cylinder 303 will move to the upper end of the active gear plate 302, and then the fixed plate 204 and the clamping frame 206 will be moved downward by starting the long electric telescopic rod 205. The driven gear cylinder 303 will mesh with the active gear plate 302, and the long rotating rod 301 will drive the first bevel gear 306 to rotate, and mesh with the second bevel gear 307 to rotate the short rotating rod 305. At this time, the bidirectional reciprocating screw 304 starts to rotate under the action of the transmission wheel 308, and the reciprocating slider 310 starts to rotate. The rod body of the bidirectional reciprocating screw 304 moves back and forth, and at the same time drives the connecting rod 311, the transmission rod 312 and the intermediate gear 313 to move back and forth. In the process of the short rotating rod 305 rotating, the transmission wheel 308 near the middle will rotate with the short rotating rod 305. At this time, under the action of the engagement of the toothed belt 309 and the middle transmission wheel 308, the transmission wheels 308 on both sides can rotate synchronously, thereby driving the bidirectional reciprocating screw 304 to rotate. At the same time, the bidirectional reciprocating screw 304 is provided with two sets of reciprocating thread structures for the corresponding reciprocating sliders 310 to move back and forth in two directions of a metal. When the bidirectional reciprocating screw 304 rotates, the reciprocating sliders 310 in the corresponding two directions will move in the bidirectional reciprocating screw 304. The rod bodies move and approach each other. At this time, the intermediate gear 313 will mesh with the intermediate gear frame 315 during the reciprocating movement, so that the transmission rod 312 drives the cleaning sleeve 314 to start rotating. At this time, the cleaning sleeve 314 in the moving and rotating process starts to wipe the surface of the clamping plate 208. When the clamping frame 206 reaches the position to be clamped of the sleeper product, the reciprocating slider 310 drives the cleaning sleeve 314 to move to the original position on the rod body of the bidirectional reciprocating screw 304. When the clamping plate 208 clamps the sleeper product, the servo motor 201 is started again to make the one-way slider 203 drive the clamping frame 206 to move a certain distance in the direction of the second roller conveyor 102, so that the driven gear cylinder 303 does not mesh with the active gear plate 302, thereby Once, wipe and clean it, which can effectively reduce foreign matter and impurities adhering to the surface of the clamping plate 208, improve the stability of the clamping plate 208 when clamping the rail sleeper, and then start the long electric telescopic rod 205 to make the clamping frame 206 move downward, at this time the bottom plate 410 will drive the L-shaped connecting frame 411, the guide sleeve 408 and the middle tooth plate 409 to move downward, at this time the middle tooth plate 409 will mesh with the middle gear cylinder 405, and make the positioning tooth plate 403 drive the sealing plate 402 to move upward, at this time the interior of the negative pressure box 401 will generate negative pressure under the action of the upward movement of the sealing plate 402, at this time the second one-way valve 419 is in a closed state, the first one-way valve 417 is in an open state, at this time under the action of the negative pressure inside the negative pressure box 401,The ventilation box 412 starts to absorb air through the ventilation head 413, and the cleaning sleeve 314 rotates and reciprocates on the outer wall of the clamping plate 208. At this time, the dust generated in the process of the cleaning sleeve 314 cleaning the clamping plate 208 will be adsorbed by the ventilation head 413, thereby reducing the phenomenon of dust impurities adhering to the surface of the clamping plate 208 again. At the same time, the gas sucked into the ventilation box 412 will pass through the bellows 420 and the second short connecting pipe 418 to enter the interior of the filter box 414. The filter net inside the filter box 414 will filter the inhaled gas, and then enter the interior of the negative pressure box 401 through the first short connecting pipe 416 and the long connecting pipe 415. When the clamping plate 208 clamps the sleeper product, the servo motor 201 is started again to make the one-way slider 203 drive the clamping frame 206 to move a certain distance in the direction of the second roller conveyor 102, so that the driven gear cylinder 303 does not mesh with the active gear plate 302. When the telescopic rod 205 makes the clamping frame 206 return to its original position, the sealing plate 402 is located at the upper end of the negative pressure box 401, and the bottom plate 410 drives the L-shaped connecting frame 411, the guide sleeve 408 and the middle tooth plate 409 to move upward. At this time, the middle tooth plate 409 will mesh with the middle gear cylinder 405 and make the positioning tooth plate 403 drive the sealing plate 402 to move downward inside the negative pressure box 401. At this time, the gas inside the negative pressure box 401 is pressurized. At this time, the pressurized gas will enter the interior of the ventilation box 412 through the long connecting tube 415 and the bellows 420, and then be sprayed to the sleeper product by multiple ventilation heads 413. At this time, some debris and dust on the surface of the sleeper product will be blown away and blown off, thereby improving the cleanliness of the surface of the sleeper product and making the stacked sleepers more tightly connected, so that the sleeper product is not easy to slide or dislocate during stacking and transportation, thereby improving the stability of the stacking.
