[0016] Beneficial effects

[0017] 1. The present invention is provided with a steam collection box and a steam generating device. When the steam generating device is started, steam can be generated. The steam enters the interior of the L-shaped bracket plate through the air outlet, and steam-cures the sleepers on the curing bracket. The excess steam enters the steam collection box through a number of air inlet nozzles. The high-temperature steam condenses with the condensation column to form water droplets. The water droplets drip downward along the condensation column and pass through the notch to be collected in the water collection tank. The water collection tank can be connected to a water pump, a water pipe and a nozzle to spray the sleepers, collect the steam and reuse it, making the equipment more energy-efficient.

The coating mechanism includes a rotating roller and a traction roller. The traction roller realizes the traction of the covering film. When the covering film is stretched, the rotating roller rotates, further causing the coil spring to deform. When the traction force on the covering film disappears, the coil spring recovers the deformation, and the rotating roller rotates in the opposite direction to realize the winding of the covering film. The rotating roller, traction roller and fixed roller can realize better covering of the covering film.

[0019] 3. The present invention is provided with a taking-out mechanism and a placement platform. The taking-out mechanism can realize neat placement of the molds before steam curing, avoiding manual placement of the molds one by one, and at the same time can realize demolding of the hardened sleepers. The demolded sleepers can fall onto the placement platform and then be transferred to the curing bracket through the placement platform for secondary curing. The whole process has low manual participation, avoiding manual placement of molds, demolding, and movement of the demolded sleepers, so that steam curing and subsequent spray curing are more consistent. Spray curing can continue after steam curing, avoiding the step-by-step implementation of steam curing and spray curing, and the overall curing efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] 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 any creative efforts shall fall within the scope of protection of the present invention.

[0023] like Figure 1 As shown, an energy-saving concrete sleeper steam curing device provided by an embodiment of the present invention includes an integral bracket 100, on which a side plate 200 is slidably provided. Figure 2 When the side panel 200 slides toward the interior of the integral bracket 100 , a seal can be formed inside the integral bracket 100 .

[0024] A maintenance bracket 300 is installed inside the integral bracket 100 , a coating mechanism 400 is installed on the maintenance bracket 300 , a removal mechanism 500 is installed at the end of the maintenance bracket 300 , and a placement platform 600 is installed below the maintenance bracket 300 .

[0025] like Figure 3 As shown, the overall bracket 100 includes an L-shaped bracket plate 101, a steam collection box 102 is fixedly provided on the top of the L-shaped bracket plate 101, a first mounting plate 103 is fixedly provided inside the steam collection box 102, the first mounting plate 103 is tilted, and a plurality of air inlet nozzles 106 are arranged in an array on the first mounting plate 103. The air inlet nozzle 106 is in the shape of an inverted funnel, and the top diameter of the air inlet nozzle 106 is smaller than the bottom diameter. A condensation column 107 is fixedly provided at the upper end of the steam collection box 102, and a steam generating device 104 is fixedly provided on the outside of the steam collection box 102. The steam generating device 104 is provided with an air outlet 105. When the steam generating device 104 is started, steam can be generated, and the steam enters the interior of the L-shaped bracket plate 101 through the air outlet 105, which is conducive to the maintenance support. The sleepers on the frame 300 are steam-cured, and excess steam enters the steam collection box 102 through several air inlet nozzles 106. The high-temperature steam condenses with the condensation column 107 to form water droplets, which drip down along the condensation column 107 to the first mounting plate 103. The air inlet nozzle 106 is set as an inverted funnel to prevent the water droplets and the water accumulated on the first mounting plate 103 from flowing back to the maintenance bracket 300. A slot 108 is opened on the L-shaped bracket plate 101 at the bottom of the first mounting plate 103. The water accumulated on the first mounting plate 103 is discharged through the slot 108. A drain plate 109 is fixedly provided on the L-shaped bracket plate 101 below the slot 108. The drain plate 109 is set at an angle, and the water flowing out of the slot 108 is drained through the drain plate 109.

[0026] like Figure 3 As shown, the side plate 200 includes a U-shaped plate 201, and the L-shaped bracket plate 101 is symmetrically provided with a through groove. The two U-shaped edges of the U-shaped plate 201 slide in cooperation with the through groove. When the U-shaped plate 201 moves toward the inside of the L-shaped bracket plate 101 bracket, the U-shaped plate 201 gradually slides into the inside of the L-shaped bracket plate 101, closing the area on both sides of the L-shaped bracket plate 101. A water collecting trough 202 is also fixedly provided inside the U-shaped plate 201, and a window 203 is provided on the U-shaped plate 201 above the water collecting trough 202. The ends of the two U-shaped edges of the U-shaped plate 201 are both provided with a U-shaped groove 204. Figure 2As shown, after the U-shaped plate 201 is slid to the innermost part of the L-shaped bracket plate 101, the sealing plates are inserted into the U-shaped grooves 204 on both sides. The U-shaped plate 201, the L-shaped bracket plate 101, the steam collection box 102, and the sealing plates make the entire device fully enclosed, preventing steam from escaping and enabling steam curing of the sleepers. At this time, the water collection trough 202 on the U-shaped plate 201 is also moved below the drainage plate 109. The condensed water flows through the drainage plate 109 into the water collection trough 202 for collection. The collected water can be used for subsequent coating curing. The water collection trough 202 can be connected to a water pump, water pipe, and nozzle to spray the sleepers.

[0027] like Figure 4 As shown, the maintenance bracket 300 includes two U-shaped support bases 301, and the two U-shaped support bases 301 are fixedly connected by two horizontal plates 302. The two horizontal plates 302 are symmetrically arranged, and the same end of the two horizontal plates 302 is fixed with an end plate 310. The side positions of the two horizontal plates 302 are fixed with side plates 303. The two side plates 303 are fixed to the outside of the two horizontal plates 302. A second mounting plate 309 is also fixed between the two U-shaped support bases 301, and a T-shaped plate 304 is also fixed on one of the side plates 303. Figure 6 As shown, a mounting groove 306 is provided on the vertically arranged plate on the T-shaped plate 304, two slide rods 307 are fixed in the mounting groove 306, a first rack 308 is fixed on the horizontally arranged plate on the T-shaped plate 304, and a first limiting groove 305 is provided on the side of the horizontally arranged plate on the T-shaped plate 304.

[0028] like Figure 4 and 6 As shown, the laminating mechanism 400 includes a U-shaped seat 401, a first telescopic cylinder 404 is rotatably provided inside the U-shaped seat 401, a first gear 402 is rotatably provided on the side of the outer side of the U-shaped seat 401, the U-shaped seat 401 slides with the first limiting groove 305, the first gear 402 is meshed with the first rack 308 for transmission, and a first limiting block (not marked in the figure) is also rotatably provided on the first gear 402, the first limiting block slides with the two slide bars 307, a first motor is provided inside the first limiting block, the first motor drives the first gear 402 to rotate, and further realizes the lateral movement of the U-shaped seat 401, and a second motor 403 is provided at the rotation connection between the U-shaped seat 401 and the first telescopic cylinder 404, and the second motor 403 drives the first telescopic cylinder 404 to rotate relative to the U-shaped seat 401, so as to realize the angle change of the first telescopic cylinder 404, as shown in FIG. Figure 4 As shown, the output end of the first telescopic cylinder 404 is fixed with a first mounting block 405, and the first mounting block 405 is fixed with a traction roller 406, as shown in FIG. Figure 7As shown, a first rotating arm 408 is fixedly provided on the outer side of the U-shaped support base 301, and a coil spring mechanism 410 is installed on the first rotating arm 408. The coil spring mechanism 410 is connected to a rotating roller 409. The coil spring mechanism 410 is a mechanical device that uses an elastic element (such as a spiral spring, a clockwork spring, etc.) to store and release energy. When an external force acts on the coil spring (such as through rotation or stretching), the spring elastically deforms and converts mechanical energy into potential energy 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 coil spring mechanism includes a built-in coil spring 410 and a rotating shaft. The deformation of the coil spring can realize the rotation of the rotating shaft, and the rotating shaft is fixedly connected to the rotating roller 409. The 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 coil spring to deform. When the traction on the covering film 407 disappears, the coil spring recovers its deformation, and the rotating roller 409 rotates in the opposite direction to realize the winding of the covering film 407.

[0029] The other end of the covering film 407 is fixedly connected to the traction roller 406, and a second rotating arm 412 is rotatably provided on the side plate 303 on the same side of 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 rotating connections are 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, and the output end of the second telescopic cylinder 413 and the extended end of the second telescopic rod 414 are fixedly connected to the second mounting block 415. A fixed roller 416 is fixed 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.

[0030] Combine Figure 4 、 Figure 6 and Figure 7As shown, the coating mechanism 400 in this embodiment is used after steam curing and the cured sleeper has been demoulded and placed on the curing bracket 300. First, the first telescopic cylinder 404 is adjusted to a vertical state and is in an extended state. Then the first gear 402 rotates, and the first gear 402 engages with the first rack 308 to transmit the lateral movement of the first telescopic cylinder 404. During the lateral movement of the first telescopic cylinder 404, the traction roller 406 will be driven to move synchronously laterally. 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 winding spring mechanism 410, that is, 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 bracket 300, the traction roller 406 and the fixed roller 416 are adjusted to achieve full coverage of the top of the curing bracket 300 by the covering film 407. The demoulded rail sleepers are placed in the maintenance bracket 300. Before laminating, the rail sleepers need to be sprayed first, and after laminating, they can be sprayed again to achieve secondary maintenance of the rail sleepers.

[0031] like Figure 4 As shown, the removal 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 threadedly engaged on 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 limit blocks 504 are symmetrically provided on both sides of the mating block 503, and movable plates 506 are slidingly provided on both sides of the transfer plate 505. The sliding connection between the movable plate 506 and the transfer plate 505 can be achieved by a third cylinder, and the output end of the third cylinder is connected to the movable plate 506. The distance between the movable plates 506 on both sides is changed by the extension and contraction of the output end of the third cylinder. A first clamping arm 507 is rotatably provided on one end of the movable plate 506, and a rectangular groove 509 is further provided on the movable plate 506. A second threaded rod 510 is rotatably provided in the rectangular groove 509. The end of the second threaded rod 510 is connected to a fourth motor, and the fourth motor is fixedly connected to the movable plate 506. When the fourth motor rotates, the second threaded rod 510 can be rotated. The second threaded rod 510 is threadedly engaged with a third limit block 511. A second clamping arm 508 is rotatably provided on the third limit block 511. The second clamping arm 508 is rotatably connected to the first clamping arm 507. When the second threaded rod 510 is rotated, the second clamping arm 508 is rotatably connected to the first clamping arm 507. When 510 rotates, the third limit block 511 slides in the rectangular groove 509. When the third limit 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, which cooperates with the change in the spacing between the movable plates 506 on both sides to realize the clamping function. At the same time, when clamping is not needed, 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 are hidden on the movable plate 506.

[0032] like Figure 8 As shown, the side end surfaces of the two U-shaped support bases 301 are rotatably provided with a third mounting plate 512, the rotation connection between the U-shaped support base 301 and the third mounting plate 512 is driven by a fifth motor 513, and the fifth motor 513 is fixedly connected to the U-shaped support base 301, and the two third mounting plates 512 are rotatably provided with a rectangular plate 515, and the rotation connection between the third mounting plate 512 and the rectangular plate 515 is driven by a sixth motor 514, and the sixth motor 514 is fixedly connected to the third mounting plate 512, and the two rectangular plates 515 are provided with a second limiting groove 516, as shown. Figure 10As shown, when the first threaded rod 501 drives the transfer mechanism to move horizontally, the second limit block 504 on the transfer mechanism gradually moves into the second limit groove 516 and cooperates therewith. When the transfer mechanism is completely separated from the first threaded rod 501 and the first limit rod 502, the transfer mechanism moves to a position between the two rectangular plates 515 and cooperates with the two rectangular plates 515 to form a whole (it should be noted that at the end of the threaded cooperation between the transfer mechanism and the first threaded rod 501, it may be necessary to manually push forward to achieve complete separation of the transfer mechanism from the first threaded rod 501 and the first limit rod 502. Similarly, when the transfer mechanism needs to return to the first threaded rod 501 and the first limit rod 502, it also requires human intervention and push).

[0033] like Figure 9 As shown, several un-demolded sleepers and molds are placed on the maintenance bracket 300, as shown in FIG. Figure 4 、 Figure 5 and Figure 7 As shown, when in use, the transfer mechanism is controlled to move to the bottom of the outermost mold, and then the second clamping arm 508 and the first clamping arm 507 are rotated to a triangle shape, and the position of the movable plate 506 is adjusted so that the second clamping arm 508 and the first clamping arm 507 clamp and fix the mold, and then the transfer mechanism is continued to move until the transfer mechanism is completely separated from the first threaded rod 501 and the first limiting rod 502. At this time, the transfer mechanism drives the mold to move to the position between the two rectangular plates 515, and the six motors 514 drive the two rectangular plates 515. Flip, at this time the two rectangular plates 515 drive the transfer mechanism and the mold thereon to flip synchronously, and then cooperate with manual or mechanical knocking to demould the rail sleepers formed in the mold. The demoulded rail sleepers fall onto the placement platform 600 and are neatly placed. After demoulding, the mold needs to be taken out manually, and the above steps are repeated to complete the demoulding of the rail sleepers after steam curing. In 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, so as to ensure that the transfer mechanism can move to the bottom of the next mold.

The placement plate 608 can move in the movable groove 607. This embodiment provides a movement method of the placement plate 608 and the movable groove 607. Specifically, a second rack is fixed on the bottom surface of the movable groove 607, and a gear is provided for rotation at the bottom of the placement plate 608. When the limit bar 605 is located in the movable groove 607, the second rack is engaged with the second gear, and the second gear is driven to rotate by the seventh motor to realize the horizontal movement of the placement plate 608. At this time, the third threaded rod 601 remains stationary. During the horizontal movement of the placement plate 608, the third telescopic cylinder 604 and the placement plate 608 move relative to each other, and the block on the third telescopic cylinder 604 moves to the end of the card slot on the back of the placement plate 608 (such as Figure 12 As shown), at this time, the third telescopic cylinder 604 is controlled to extend to lift the placement plate 608 upward, and then the third threaded rod 601 is driven to rotate, and the third telescopic cylinder 604 begins to move, and drives the placement plate 608 on it to move synchronously toward the inside of the maintenance bracket 300 until it moves to the innermost side, then the third telescopic cylinder 604 is shortened, and drives the placement plate 608 on it to descend, and the placement plate 608 is placed until the limit bar 605 on the placement plate 608 returns to the moving groove 607, the second rack and the second gear are engaged, and the third telescopic cylinder 604 returns to the position shown in FIG. Figure 11 Position shown.

[0035] like Figure 9 、 Figure 11 and Figure 12 As shown, when the taking-out mechanism 500 starts to take out the molds one by one and flips them for demoulding, the placing plate 608 moves in coordination therewith to ensure that the placing plate 608 is always located below the flipped mold. The placing plate 608 is used to receive the rail sleepers after demoulding. When the placing plate 608 is filled with rail sleepers, the placing plate 608 rises to the top of the two horizontal plates 302 (as shown in FIG. Figure 4As shown), when the front sleeper contacts the end plate 310, the placement plate 608 is controlled to descend, and the sleepers on the placement plate 608 are neatly transferred to the two cross plates 302. At this time, the water collecting trough 202 is cooperated to spray, and after spraying, the coating mechanism 400 is controlled to coat, and a second spraying is performed to achieve secondary maintenance of the sleepers.
