Description

Technical Field

[0001] This invention relates to the field of railway sleeper maintenance, and in particular to an energy-saving steam curing device for concrete railway sleepers. Background Technology

[0002] Railway sleepers, also known as railway sleepers, are a type of railway component. Initially, railway sleepers were made of wood, which has good elasticity and insulation properties and is less affected by temperature changes in the surrounding environment. However, with the depletion of forest resources and the increasing awareness of environmental protection, steel sleepers and reinforced concrete sleepers began to be produced to replace railway sleepers.

[0003] During the production of concrete railway sleepers, curing is essential to ensure their quality. Curing should combine steam curing with subsequent moisture retention. After steam curing, the sleepers should be immediately covered with geotextile or plastic film and continuously sprayed with water to maintain moisture.

[0004] However, steam curing and subsequent moisturizing are usually carried out in separate steps, which also require manual demolding and handling, thus affecting production efficiency. Summary of the Invention

[0019] Beneficial effects

[0020] 1. This invention features a steam collection box and a steam generator. Activating the steam generator produces steam, which enters the L-shaped support plate through the outlet to steam-cur the sleepers on the maintenance support. Excess steam enters the steam collection box through several inlets. The high-temperature steam condenses with the condenser column to form water droplets. These droplets drip down the condenser column and are collected in a water collection tank. The water collection tank can be connected to a water pump, water pipes, and nozzles to spray the sleepers, collecting and reusing the steam, thus making the equipment more energy-efficient.

[0021] 2. The present invention provides a covering mechanism to cover the sleepers after steam curing. The covering mechanism includes a rotating roller and a traction roller. The traction roller pulls the covering film. When the covering film is stretched, the rotating roller rotates, which further deforms the coil spring. When the traction force on the covering film disappears, the coil spring returns to its original shape, and the rotating roller rotates in the opposite direction to roll up the covering film. The rotating roller, traction roller and fixed roller can achieve better coverage of the covering film.

[0022] 3. This invention features a removal mechanism and a placement platform. The removal mechanism allows for the neat placement of molds before steam curing, avoiding manual placement of each mold. It also enables the demolding of hardened sleepers. The demolded sleepers fall onto the placement platform and are then transferred to the curing support for secondary curing. The entire process involves minimal human intervention, avoiding manual placement and demolding of molds, as well as the movement of demolded sleepers. This ensures a smooth transition between steam curing and subsequent spray curing, allowing spray curing to continue after steam curing. This avoids the need for separate steam and spray curing processes, resulting in high overall curing efficiency. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1 As shown in the figure, an energy-saving steam curing device for concrete railway sleepers provided in this embodiment of the invention includes an overall support 100, on which side plates 200 are slidably mounted. Figure 2 When the side plate 200 shown slides into the interior of the overall bracket 100, it can form a seal inside the overall bracket 100.

[0039] The overall support 100 has a maintenance support 300 installed inside, a film covering mechanism 400 installed on the maintenance support 300, a removal mechanism 500 installed at the end of the maintenance support 300, and a placement platform 600 installed below the maintenance support 300.

[0040] like Figure 3 As shown, the overall support 100 includes an L-shaped support plate 101. A steam collection box 102 is fixedly mounted on the top of the L-shaped support plate 101. A first mounting plate 103 is fixedly mounted inside the steam collection box 102. The first mounting plate 103 is inclined and has several air inlets 106 arranged in an array on it. The air inlets 106 are inverted funnel-shaped, with the top diameter of the air inlets 106 being smaller than the bottom diameter. A condensation column 107 is fixedly mounted at the upper end inside the steam collection box 102. A steam generator 104 is fixedly mounted on the outside of the steam collection box 102. The steam generator 104 has an air outlet 105. Activating the steam generator 104 generates steam, which enters the L-shaped support plate 101 through the air outlet 105, thus supporting the maintenance support. The sleepers on the support frame 300 are steam-cured. Excess steam enters the steam collection box 102 through several air inlets 106. The high-temperature steam condenses with the condenser column 107 to form water droplets. The water droplets drip down the condenser column 107 onto the first mounting plate 103. The air inlets 106 are designed as inverted funnels to prevent the water droplets and the water accumulated on the first mounting plate 103 from flowing back onto the curing support frame 300. A slot 108 is opened at the bottom of the first mounting plate 103 on the L-shaped support plate 101. The water accumulated on the first mounting plate 103 is discharged through the slot 108. A diversion plate 109 is fixedly installed on the L-shaped support plate 101 below the slot 108. The diversion plate 109 is inclined so that the water flowing out of the slot 108 is diverted through the diversion plate 109.

[0041] like Figure 3As shown, the side panel 200 includes a U-shaped plate 201, and symmetrical through slots are provided on the L-shaped support plate 101. The two U-shaped sides of the U-shaped plate 201 are slidably engaged with the through slots. When the U-shaped plate 201 moves towards the interior of the L-shaped support plate 101, the U-shaped plate 201 gradually slides into the interior of the L-shaped support plate 101, closing off the two sides of the L-shaped support plate 101. A water collection trough 202 is also fixedly provided inside the U-shaped plate 201. A window 203 is provided on the U-shaped plate 201 above the water collection trough 202. U-shaped grooves 204 are provided at the very ends of the two U-shaped sides of the U-shaped plate 201. Figure 2 As shown, after the U-shaped plate 201 slides to the innermost part of the L-shaped support plate 101, the sealing plate is then inserted into the U-shaped grooves 204 on both sides. The U-shaped plate 201, L-shaped support plate 101, steam collection box 102, and sealing plate make the entire device fully enclosed, preventing steam from escaping and enabling steam curing of the sleepers. At this time, the water collection tank 202 on the U-shaped plate 201 also moves to below the diversion plate 109. The condensed water flows through the diversion plate 109 into the water collection tank 202 for collection. The collected water can be used for subsequent membrane curing. The water collection tank 202 can be connected to a water pump, water pipes, and nozzles to spray the sleepers.

[0042] like Figure 4 As shown, the maintenance bracket 300 includes two U-shaped support bases 301, which are fixedly connected by two horizontal plates 302. The two horizontal plates 302 are symmetrically arranged, and an end plate 310 is fixedly provided at the same end of each horizontal plate 302. A side plate 303 is fixedly provided on the side of each horizontal plate 302, and the two side plates 303 are fixedly provided on the outer side of the two horizontal plates 302. A second mounting plate 309 is also fixedly provided between the two U-shaped support bases 301. A T-shaped plate 304 is also fixedly provided on one of the side plates 303. Figure 6 As shown, a mounting groove 306 is provided on the vertically arranged plate of the T-shaped plate 304, and two sliding rods 307 are fixedly installed in the mounting groove 306. A first rack 308 is fixedly installed on the horizontally arranged plate of the T-shaped plate 304, and a first limiting groove 305 is provided on the side of the horizontally arranged plate of the T-shaped plate 304.

[0043] like Figure 4 and 6As shown, the coating mechanism 400 includes a U-shaped seat 401. A first telescopic cylinder 404 is rotatably mounted inside the U-shaped seat 401. A first gear 402 is rotatably mounted on the outer side of the U-shaped seat 401. The U-shaped seat 401 is slidably engaged with a first limiting groove 305. The first gear 402 meshes with a first rack 308 for transmission. A first limiting block (not marked in the figure) is also rotatably mounted on the first gear 402. The first limiting block is slidably engaged with two sliding rods 307. A first motor is installed inside the first limiting block. The first motor drives the first gear 402 to rotate, further realizing the lateral movement of the U-shaped seat 401. A second motor 403 is installed at the rotatable connection between the U-shaped seat 401 and the first telescopic cylinder 404. The second motor 403 drives the first telescopic cylinder 404 to rotate relative to the U-shaped seat 401, realizing the angle change of the first telescopic cylinder 404. Figure 4 As shown, a first mounting block 405 is fixedly mounted on the output end of the first telescopic cylinder 404, and a traction roller 406 is fixedly mounted on the first mounting block 405, as shown. Figure 7 As shown, a first rotating arm 408 is fixedly provided on the outer side of the U-shaped support base 301. A coiling spring mechanism 410 is installed on the first rotating arm 408. A rotating roller 409 is connected to the coiling spring mechanism 410. The coiling spring mechanism 410 is a mechanical device that uses elastic elements (such as coil springs, clock springs, etc.) to store and release energy. When an external force is applied to the coiling spring (such as through rotation or stretching), the spring undergoes elastic deformation, converting mechanical energy into potential energy for storage. After the external force is removed, the spring returns to its original state due to the elastic restoring force, releasing the stored potential energy and driving the mechanism to move. The coiling spring mechanism includes a coiling spring built into 410 and a rotating shaft. The deformation of the coiling spring can realize the rotation of the rotating shaft. The rotating shaft is fixedly connected to the rotating roller 409. A covering film 407 is wound on the rotating roller 409. When the covering film 407 is stretched, the rotating roller 409 rotates, further causing the coiling spring to deform. When the traction force on the covering film 407 disappears, the coiling spring returns to its original deformation, and the rotating roller 409 rotates in the opposite direction to realize the winding of the covering film 407.

[0044] The other end of the covering film 407 is fixedly connected to the traction roller 406. A second rotating arm 412 is rotatably provided on the side plate 303 on the same side as the U-shaped support base 301. The first rotating arm 408 and the second rotating arm 412 are rotatably connected to the U-shaped support base 301 and the side plate 303 through the same rotating shaft 411, and the rotatable connection is driven by a third motor. A second telescopic rod 414 and a second telescopic cylinder 413 are fixedly provided on the second rotating arm 412. The output end of the second telescopic cylinder 413 and the extension end of the second telescopic rod 414 are fixedly connected to the second mounting block 415. A fixed roller 416 is fixedly provided on the second mounting block 415. When in use, the fixed roller 416 can support the covering film 407 between the traction roller 406 and the rotating roller 409, thereby adjusting the position of the covering film 407.

[0045] Combination Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, the covering mechanism 400 is used after steam curing and the cured sleeper has been demolded and placed on the curing support 300. First, the first telescopic cylinder 404 is adjusted to a vertical state and extended. Then, the first gear 402 rotates, and the first gear 402 meshes with the first rack 308 to realize the lateral movement of the first telescopic cylinder 404. During the lateral movement of the first telescopic cylinder 404, the traction roller 406 will move laterally in sync. During the movement of the traction roller 406, the covering film 407 will be pulled. Since the other end of the covering film 407 is wound on the rotating roller 409, and the rotating roller 409 is connected to the coil spring mechanism 410, when one end of the covering film 407 is pulled outward, the covering film 407 will be pulled out. When the length of the covering film 407 is greater than the length of the curing support 300, the covering film 407 will fully cover the top of the curing support 300 by adjusting the traction roller 406 and the fixed roller 416. The maintenance support 300 contains the demolded sleepers. Before covering with film, the sleepers need to be sprayed. After covering with film, they can be sprayed a second time to achieve secondary maintenance of the sleepers.

[0046] like Figure 4 As shown, the extraction mechanism 500 includes a first threaded rod 501 and a first limiting rod 502. The first threaded rod 501 is rotatably connected to the second mounting plate 309, and the first limiting rod 502 is fixedly connected to the second mounting plate 309. A transfer mechanism is threaded onto the first threaded rod 501, and the transfer mechanism is slidably engaged with the first limiting rod 502. Figure 5As shown, the transfer mechanism includes a transfer plate 505, a mating block 503 is fixedly provided at the bottom of the transfer plate 505, and second limiting blocks 504 are symmetrically arranged on both sides of the mating block 503. Moving plates 506 are slidably provided on both sides of the transfer plate 505. The sliding connection between the moving plates 506 and the transfer plate 505 can be achieved by a third cylinder. The output end of the third cylinder is connected to the moving plates 506. The distance between the two moving plates 506 is changed by the extension and contraction of the output end of the third cylinder. A first clamping arm 507 is rotatably mounted on one end of a movable plate 506. A rectangular groove 509 is also provided on the movable plate 506, within which a second threaded rod 510 is rotatably mounted. A fourth motor is connected to the end of the second threaded rod 510, and the fourth motor is fixedly connected to the movable plate 506. When the fourth motor rotates, the second threaded rod 510 rotates. A third limiting block 511 is threaded onto the second threaded rod 510, and a second clamping arm 508 is rotatably mounted on the third limiting block 511. The second clamping arm 508 is rotatably connected to the first clamping arm 507. When the second threaded rod... When 510 rotates, the third limiting block 511 slides in the rectangular groove 509. When the third limiting block 511 moves to the front end of the rectangular groove 509, the angle between the second clamping arm 508 and the first clamping arm 507 becomes smaller, and the second clamping arm 508 and the first clamping arm 507 form a triangular clamping plate. The clamping function is realized by changing the distance between the two moving plates 506. At the same time, when clamping is not required, the second clamping arm 508 and the first clamping arm 507 can be controlled to rotate to a horizontal position, and the second clamping arm 508 and the first clamping arm 507 can be hidden on the moving plate 506.

[0047] like Figure 8 As shown, a third mounting plate 512 is rotatably mounted on the side end face of each of the two U-shaped support bases 301. The rotatable connection between the U-shaped support base 301 and the third mounting plate 512 is driven by a fifth motor 513, which is fixedly connected to the U-shaped support base 301. A rectangular plate 515 is rotatably mounted on each of the two third mounting plates 512. The rotatable connection between the third mounting plate 512 and the rectangular plate 515 is driven by a sixth motor 514, which is fixedly connected to the third mounting plate 512. A second limiting groove 516 is provided on each of the two rectangular plates 515. Figure 10As shown, during the lateral movement of the transfer mechanism driven by the first threaded rod 501, the second limiting block 504 on the transfer mechanism gradually moves into the second limiting groove 516 and cooperates with it. When the transfer mechanism is completely separated from the first threaded rod 501 and the first limiting rod 502, the transfer mechanism moves to the position between the two rectangular plates 515 and cooperates with the two rectangular plates 515 to form a whole. (It should be noted that when the transfer mechanism is no longer threadedly engaged with the first threaded rod 501, it may be necessary to push it forward manually to achieve complete separation of the transfer mechanism from the first threaded rod 501 and the first limiting rod 502. Similarly, when the transfer mechanism needs to return to the first threaded rod 501 and the first limiting rod 502, it also needs to be pushed manually.)

[0048] like Figure 9 As shown, several un-demolded sleepers and molds are placed on the maintenance support 300, such as... Figure 4 , Figure 5 and Figure 7 As shown, during use, the control transfer mechanism moves to below the outermost mold, then the second clamping arm 508 and the first clamping arm 507 are rotated into a triangular shape, and the position of the moving plate 506 is adjusted so that the second clamping arm 508 and the first clamping arm 507 clamp and fix the mold. Then, the transfer mechanism continues to move until it is completely separated from the first threaded rod 501 and the first limit rod 502. At this time, the transfer mechanism moves the mold together to the position between the two rectangular plates 515, and the two rectangular plates 515 are driven by the sixth motor 514. The two rectangular plates 515 rotate synchronously with the transfer mechanism and the mold. With manual or mechanical tapping, the sleeper formed in the mold is demolded. The demolded sleeper falls onto the placement platform 600 and is placed neatly. After demolding, the mold needs to be removed manually. Repeat the above steps to complete the demolding of the sleeper after steam curing. During the process of the transfer mechanism moving the mold again, it is necessary to control the second clamping arm 508 and the first clamping arm 507 to rotate to a horizontal position. This ensures that the transfer mechanism can move to the bottom of the next mold.

[0049] like Figure 9 and Figure 11As shown, the placement platform 600 includes a third threaded rod 601 fixedly and rotatably mounted on an L-shaped support plate 101, and a second limiting rod 602 fixedly mounted on the L-shaped support plate 101. The third threaded rod 601 is driven by a ninth motor, which is fixedly mounted on the L-shaped support plate 101. A moving block 603 is threadedly fitted onto the third threaded rod 601. A third telescopic cylinder 604 is fixedly mounted on the moving block 603. A locking block is fixedly mounted at the output end of the third telescopic cylinder 604. A placement plate 608 is slidably mounted above the third telescopic cylinder 604. A rectangular slot is provided on the back of the placement plate 608, and the length of the slot is slightly less than the length of the placement plate 608. Tracks 606 are symmetrically fixed on two U-shaped support bases 301. Each track 606 has a moving groove 607 on its upper surface. A matching limiting strip 605 is also fixedly provided at the bottom of the placement plate 608. The length of the limiting strip 605 is the same as the length of the placement plate 608. The placement plate 608 can move within the moving groove 607. This embodiment provides a method for the movement of the placement plate 608 and the moving groove 607. Specifically, a second rack is fixedly provided on the bottom surface of the moving groove 607, and a gear is rotatably provided at the bottom of the placement plate 608. When the limiting strip 605 is located within the moving groove 607, the second rack and the second gear mesh. The horizontal movement of the placement plate 608 can be achieved by driving the second gear to rotate through the seventh motor. At this time, the third threaded rod 601 remains stationary. During the horizontal movement of the placement plate 608, the third telescopic cylinder 604 moves relative to the placement plate 608. The locking block on the third telescopic cylinder 604 will move to the very end of the locking groove on the back of the placement plate 608 (e.g., Figure 12 (As shown), at this time, control the third telescopic cylinder 604 to extend and lift the placement plate 608 upward, then drive the third threaded rod 601 to rotate, the third telescopic cylinder 604 begins to move, and drives the placement plate 608 on it to move synchronously towards the inside of the maintenance bracket 300 until it moves to the innermost side, then the third telescopic cylinder 604 shortens and drives the placement plate 608 on it to descend, until the limit strip 605 on the placement plate 608 returns to the moving groove 607, the second rack and the second gear mesh, and the third telescopic cylinder 604 returns to the position as shown. Figure 11 The location shown.

[0050] like Figure 9 , Figure 11 and Figure 12 As shown, when the removal mechanism 500 begins to remove the molds one by one and flips them for demolding, the placement plate 608 moves in coordination with it to ensure that the placement plate 608 is always located below the flipped mold. The placement plate 608 is used to receive the demolded sleepers. When the placement plate 608 is neatly filled with sleepers, the placement plate 608 rises above the two horizontal plates 302 (as shown). Figure 4As shown, when the foremost sleeper contacts the end plate 310, the placement plate 608 is lowered, and the sleeper on the placement plate 608 is neatly transferred to the two horizontal plates 302. At this time, it is sprayed in conjunction with the water collection tank 202. After spraying, the film covering mechanism 400 is controlled to cover the sleeper and a second spray is performed to achieve secondary maintenance of the sleeper.
