Description

Technical Field

[0001] This application relates to the field of steam curing technology, and particularly to steam curing systems. Background Technology

[0002] With the rapid development of high-speed railways in my country, the demand for high-quality track slabs is increasing, which places higher demands on the quality and production efficiency of track slabs. In actual production, the production cycle of track slabs is mainly shortened by steam curing. Specifically, the track slabs are placed directly in a steam-filled curing station to accelerate the concrete setting speed, enabling newly poured track slabs to meet the requirements of engineering use in a short time, thus greatly shortening the production period of track slabs.

[0003] Therefore, steam curing is crucial for ensuring track slab quality and improving production efficiency. Existing steam curing processes for track slabs include at least pre-curing, heating, heat preservation, and cooling, each with different temperature requirements. Multiple steam curing stations with varying temperatures are set up in the continuous kiln to match the different processes within the steam curing procedure. However, moving the track slabs between these stations requires manual handling, which is physically demanding and increases the risk of burns for workers. Furthermore, manual operation compromises timeliness and consistency, potentially impacting track slab quality and production efficiency.

[0004] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Summary of the Invention

[0005] The purpose of this application is to provide a steam curing system to solve or alleviate the problems existing in the prior art.

[0006] To achieve the above objectives, this application provides the following technical solution: a steam curing system, comprising:

[0007] A track trolley, on which the track trolley and track trolley mold are mounted;

[0008] A continuous row of kilns, wherein the continuous row of kilns has at least two layers of steam curing channels in the vertical direction, wherein the steam curing channels have a first end and a second end in the extension direction, wherein there are multiple steam curing stations between the first end and the second end, wherein a trolley translation device is provided in the steam curing channel, wherein the trolley translation device can drive the track plate trolley to move in the extension direction of the steam curing channel;

[0010] The trolley translation device includes a power unit, a chain, and a jacking component. The chain extends in the same direction as the steam curing channel. The power unit drives the chain to move from the first end to the second end in the steam curing channel. The jacking component is fixed to the chain and is used to engage with the track trolley to move the track trolley toward the second end when the chain moves from the first end to the second end.

[0011] Furthermore, the power unit can reverse, driving the chain to move from the second end to the first end in the steam curing channel when it reverses.

When the limiting telescopic cylinder is in position, the positioning pin overlaps at least partially with the second-layer positioning adapter structure and the third-layer positioning adapter structure in the vertical direction, and the positioning component limits the lifting frame in the vertically downward direction.

[0039] When the output end of the limiting telescopic cylinder is reset, the positioning pin does not overlap with the second-layer positioning adapter structure and the third-layer positioning adapter structure in the vertical direction, and the positioning component releases the limiting effect on the lifting frame.

[0040] Furthermore, the guide rails are in two sets, with the end faces of the two sets of guide rails located at the four corners of a virtual quadrilateral. The guide rails are provided with guide grooves, which are V-shaped grooves, and the openings of the guide grooves of one set of guide rails are opposite each other.

[0041] The guide rail adapter structure includes a guide wheel and a guide plate. The guide wheel has a guide annular surface, and the cross-section of the guide annular surface is V-shaped.

[0042] The guide plate has a guide surface, which is a V-shaped surface;

[0043] There are two guide plates and two guide wheels. The two guide plates are respectively guided and engaged with two guide rails located on one diagonal of the virtual quadrilateral. The two guide wheels are respectively guided and engaged with two other guide rails. The clamping arm is provided with a sliding groove, and a slider is provided in the sliding groove. The insertion rod is fixed on the slider.

[0044] The track slab transport device also includes a slider telescopic cylinder. The cylinder body of the slider telescopic cylinder is fixed on the clamping arm, and the slider is fixed at the output end of the slider telescopic cylinder. When the slider telescopic cylinder is in position, the trolley track is aligned with the rail of the steam curing station at the same height.

[0045] Furthermore, the clamping arm drive assembly includes a clamping arm telescopic cylinder and two sets of planar four-bar linkages;

[0046] The cylinder body of the clamping arm telescopic cylinder and the planar four-bar linkage are both mounted on the lifting frame.

[0050] When the positioning telescopic cylinder is in position, the pin is inserted into the positioning hole of the steam curing station on the edge of the kiln opening.

[0051] When the output end of the positioning telescopic cylinder is reset, the pin disengages from the positioning hole of the steam curing station.

[0052] Compared with the closest prior art, the technical solution of this application has the following beneficial effects:

[0053] 1) In the continuous kiln opening of the automated production line, the steam curing system automatically completes the steam curing of the first, second, third and fourth rows of track plates with molds, as well as the second and third steam curing stations. This reduces the labor intensity of workers, improves the quality and production efficiency of track plates, and reduces the chance of workers being burned.

[0054] 2) The lifting drive device adopts a wire rope fixing frame, steel wire rope, drum, winch, fixed pulley block, and moving pulley block. It has a simple structure, stable lifting, and mature technology.

[0055] 3) The first and third sections of the wire rope can be balanced by the balancing pulley system, and each wire rope is equipped with four sets of movable pulleys, which can further ensure the smooth lifting of the lifting frame.

[0056] 4) Compared to relying solely on the winch's braking to limit the position of the lifting frame, using positioning components to limit the position of the lifting frame is more precise, ensuring that the trolley track and the steel rail of the steam curing station are at the same height.

[0057] 5) The guide plate and guide wheel work together with the guide rail to ensure reliable up and down directional lifting of the lifting frame without horizontal deviation.

[0058] 6) The pallet can move horizontally, and when it moves up and down on the lifting frame after the slider telescopic cylinder is reset, interference between the pallet and structures such as the vertical guide frame is avoided.

[0059] 7) The transmission between the clamping arm and the clamping arm telescopic cylinder is achieved through a four-bar linkage, which has a simple structure, light weight, reliable transmission, and mature technology.

[0060] 8) The transmission between the four-bar linkage and the clamping arm telescopic cylinder is achieved through the push arm and the torsion shaft. The clamping arm telescopic cylinder can be set in the middle of the lifting frame to avoid interference with the structure at the edge of the lifting frame.

[0061] 9) The rod displacement sensor, controller, and electric valve can ensure that the displacement of the two rods is synchronized.

[0062] 10) Compared to relying solely on the braking of the moving motor to limit the position of the support frame, using a positioning telescopic cylinder and pins to limit the position of the support frame is more precise, ensuring that the position of the support frame is consistent with that of the steam curing station.

[0063] 11) The power unit can reverse, which makes it relatively easy to reset the chain.

[0064] 12) The structure and connection method of the pusher can avoid interference between the pusher and the protrusion during the chain reset process. The structure is simple and easy to process and manufacture.

[0065] 13) The hinge shaft is formed by a portion of the wheel axle. The hinge shaft utilizes the original structure of the roller, which is convenient for processing and manufacturing and saves costs. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0084] This application provides a steam curing system, such as... Figure 11 , Figure 12 and Figure 13As shown, the steam curing system includes: a track trolley, a continuous kiln opening 41, and a track trolley transport device. The track trolley and track trolley mold are mounted on the track trolley, which has downwardly protruding bumps 45.

[0085] The kiln opening 41 has at least two layers of steam curing channels 42 in the vertical direction (three layers in this embodiment), with four steam curing channels 42 in each layer (i.e., four rows of steam curing channels 42). The steam curing channels 42 have a first end and a second end in the extending direction, and multiple steam curing stations are located between the first end and the second end.

[0086] A trolley translation device is provided in the steam curing channel 42, which can drive the track trolley to move in the extending direction of the steam curing channel 42. The trolley translation device includes a power unit 43, a chain 44, and a pusher. The extending direction of the chain 44 is the same as the extending direction of the steam curing channel 42. The power unit 43 is used to drive the chain 44 to move from the first end to the second end in the steam curing channel 42. The pusher is fixed on the chain 44 and is used to engage with the protrusion 45 of the track trolley 5 to move the track trolley towards the second end when the chain 44 moves from the first end to the second end. The power unit 43 can reverse, driving the chain 44 to move from the second end to the first end in the steam curing channel 42.

[0087] The jacking component includes a heavy arm 47 and a light arm 46. The heavy arm 47 and the light arm 46 are integrally formed or connected to form a V-shape at the connection point. A hinge shaft 48 is provided at the connection point. The jacking component is hinged to the chain 44 through the hinge shaft 48. When the jacking component is only subjected to the forces of gravity and the chain 44 and the hinge shaft 48, the heavy arm 47 is in contact with the chain 44, and the light arm 46 extends obliquely upward. The chain 44 is provided with rollers for rolling engagement with the bottom wall of the steam curing channel 42; at least a portion of the roller axles form the hinge shaft 48.

[0088] When the chain 44 moves from the first end to the second end in the steam curing channel 42, the light arm 46 engages with the contacting protrusion 45 to stop and drive the track trolley 5 to move.

[0089] As the chain 44 moves from the second end to the first end in the steam curing channel 42, the protrusion 45 pushes the contacting pusher to swing around the hinge axis 48, so that the pusher avoids the interference of the protrusion 45 on the moving path.

[0090] The track slab transport device has at least two units, respectively located at both ends of the continuous kiln opening 41. One track slab transport device is used to transport the track slab trolley to the first end of the steam curing channel 42, and the other track slab transport device is used to receive the track slab trolley exiting from the second end of the steam curing channel 42. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the track slab transport device includes a support frame, a vertical guide frame 3, a lifting frame 4, a lifting drive device, a clamping arm 6, a clamping arm drive assembly, a pallet 34, a track slab trolley 5, a balance pulley block 14, a positioning assembly, a slider telescopic cylinder 18, a controller, a rod displacement sensor 35, a positioning telescopic cylinder 39, and a pin 37.

[0091] The support frame includes a main frame 1 and a traveling wheel mounting frame 2. The traveling wheel mounting frame 2 is fixed on the main frame 1. A moving motor 9 is installed on the traveling wheel mounting frame 2. The output end of the moving motor 9 is fixed with a traveling wheel 10 through a reducer. The traveling wheel 10 is supported on the edge of the kiln opening and is used to drive the track plate transport device to move in the kiln opening. The track plate transport device is driven by the moving motor 9 and the traveling wheel 10 on the traveling wheel mounting frame 2 to achieve accurate movement of the steam curing stations in the first, second, third and fourth rows.

[0092] The vertical guide frame 3 is fixed to the main frame 1 and has guide rails 24 extending in the vertical direction. Two opposite guide rails 24 form a group, and there are two groups of guide rails 24. The end faces of the two groups of guide rails 24 are located at the four corners of a virtual quadrilateral. The guide rails 24 are provided with guide grooves, which are V-shaped grooves, and the openings of the guide grooves of one group of guide rails 24 are opposite to each other.

[0093] The lifting frame 4 is equipped with a guide rail adapter structure, which cooperates with the guide rail 24 to guide the lifting movement of the lifting frame 4. Specifically, the guide rail adapter structure includes guide wheels 25 and guide plates 26. The guide wheels 25 have a guide annular surface with a V-shaped cross-section. The guide plates 26 have a guide surface with a V-shaped cross-section. There are two guide plates 26 and two guide wheels 25. The two guide plates 26 are respectively guided and cooperate with two guide rails 24 located on one diagonal of the virtual quadrilateral, and the two guide wheels 25 are respectively guided and cooperate with the other two guide rails 24, ensuring that the lifting frame 4 lifts and lowers in a directional manner without horizontal deviation.

[0094] like Figure 5 and Figure 6 and Figure 7As shown, two oppositely arranged clamping arms 6 form a group, and there is at least one group of clamping arms 6. The clamping arms 6 are hinged to the lifting frame 4 via hinge shafts, and each clamping arm 6 is provided with a plug rod 17. A group of clamping arms 6 corresponds to a set of clamping arm drive assemblies. The clamping arm drive assemblies are used to drive the clamping arms 6 to swing around the hinge shafts, so that the clamping arms 6 clamp or release. The clamping arm drive assembly includes a clamping arm telescopic cylinder 31 and two sets of planar four-bar linkages. The cylinder body of the clamping arm telescopic cylinder 31 and the planar four-bar linkages are both mounted on the lifting frame 4. The push rod 28 and the torsion arm 29 form part of the planar four-bar linkages. The output end of the clamping arm telescopic cylinder 31 is connected to the input end of the crank (torsion arm 29) of the two sets of planar four-bar linkages. The output ends of the two sets of planar four-bar linkages are respectively hinged to the two clamping arms 6. Specifically, the output end of the clamping arm telescopic cylinder 31 is connected to the input end of the crank of the planar four-bar linkage through the push arm 30 and the torsion shaft 32. The output end of the clamping arm telescopic cylinder 31 is hinged to one end of the push arm 30, the other end of the push arm 30 is fixedly connected to one end of the torsion shaft 32, and the other end of the torsion shaft 32 is fixedly connected to the input end of the crank of the planar four-bar linkage. The clamping arms 6 open and close during the lifting frame 4: The clamping arms 6 set on both sides of the lifting frame 4 are driven by the planar four-bar linkage, the push arm 30, and the torsion shaft 32, and are opened and closed by the clamping arm telescopic cylinder 31, thus completing the positioning and support of the track plate trolley 5, the track plate mold 40, and the pallet 34.

[0095] The tray 34 is provided with a rod insertion hole. When the clamping arm 6 clamps, the rod 17 is inserted into the rod insertion hole, and when the clamping arm 6 is released, the rod 17 is dislodged from the rod insertion hole. The clamping arm 6 is also provided with a sliding groove 19 and a roller 7. A slider 27 is provided in the sliding groove 19, and the rod 17 is fixed on the slider 27. The cylinder body of the slider telescopic cylinder 18 is fixed on the clamping arm 6, and the slider 27 is fixed at the output end of the slider telescopic cylinder 18. When the slider telescopic cylinder 18 is in the output position, the trolley track 36 is aligned with the steel rail of the steam curing station at the same height. The roller 7 rolls with the lower end face of the tray 34, which enables the tray 34 to move smoothly horizontally under the action of the rod 17 and reduces the stress on the rod 17. The insertion rod 17 between the clamping arms 6 advances and retracts the tray 34: After the insertion rod 17 between the clamping arms 6 is inserted into the insertion hole on the tray 34, it is driven by the slider telescopic cylinder 18 under the guidance of the slider 27 and the slide groove 19, so that the tray 34 rolls on the roller 7 to complete the horizontal advance and retraction.

[0096] The controller is mounted on the main frame 1. Both insertion rods 17 are equipped with insertion rod displacement sensors 35, which transmit rod position signals to the controller. The slider telescopic cylinder 18 is equipped with an electrically controlled valve, which controls the flow rate of the thrust medium input to the slider telescopic cylinder 18. The controller controls the opening degree of the electrically controlled valve, and the insertion rod displacement sensors 35 ensure synchronous displacement of the two insertion rods. The insertion rods 17, sliders 27, and slides 19, through the slider telescopic cylinder 18, complete the horizontal advancement of the track trolley 5, track mold 40, and tray 34, and precisely connect with the rails of each steam curing station.

[0097] The track trolley 5 is used to support the track trolley. The tray 34 is provided with a trolley track 36, and the track trolley 5 is supported on the trolley track 36.

The lifting drive device includes two wire rope fixing frames 11, wire rope 8, drum 16, winch 15, fixed pulley block 12, movable pulley block 33, and balance pulley block 14. The wire rope fixing frames 11 are fixed on the support frame. Both wire rope fixing frames 11 are fixed on the side beam of the main frame 1 located on one side of the drum 16. Two balance pulley blocks 14 are fixed on the side beam located on the other side of the drum 16. The positions of the two balance pulley blocks 14 correspond to the positions of the two wire rope fixing frames 11.

[0099] The two ends of the wire rope 8 are fixed to two wire rope fixing frames 11 respectively. The wire rope 8 is divided into a first section, a second section and a third section along its length. The first section of the wire rope 8 extends from one wire rope fixing frame 11 to the corresponding balance pulley group 14. The second section of the wire rope 8 extends from one balance pulley to another balance pulley group 14. The third section of the wire rope 8 extends from another wire rope fixing frame 11 to the corresponding balance pulley group 14. Part of both the first section of the wire rope 8 and the third section of the wire rope 8 are wound on the drum 16.

[0101] Four sets of movable pulley blocks 33 are installed on the lifting frame 4, and are located directly below the fixed pulley blocks 12. The movable pulley blocks 33 are in rolling contact with the wire rope 8. The wire rope fixing frame 11, the fixed pulley blocks 12, the balance pulley blocks 14 and the movable pulley blocks 33 on the lifting frame 4 are connected by the wire rope 8 and driven by the winch reducer 13, the winch 15 and the drum 16 to realize lifting, braking and lowering, braking.

[0102] The positioning assembly includes a two-layer positioning adapter structure, a three-layer positioning adapter structure, a limiting telescopic cylinder 20, and a positioning pin 21. In this embodiment, the two-layer positioning adapter structure is a two-layer positioning screw 22, and the three-layer positioning adapter structure is a three-layer positioning screw 23. In other embodiments, the two-layer positioning adapter structure and the three-layer positioning adapter structure can also be pin holes provided on the vertical guide frame 3.

[0103] Both the second-layer and third-layer positioning adapter structures are fixed on the vertical guide frame 3. The position of the second-layer positioning adapter structure corresponds to the position of the second steam curing station in the continuous kiln, and the position of the third-layer positioning adapter structure corresponds to the position of the third steam curing station in the continuous kiln. The top surfaces of the second-layer positioning screw 22 and the third-layer positioning screw 23 on the vertical guide frame 3 respectively form positioning surfaces.

[0104] The cylinder body of the limiting telescopic cylinder 20 is fixed on the lifting frame 4, and the positioning pin 21 is fixed on the output end of the limiting telescopic cylinder 20. When the limiting telescopic cylinder 20 is in position, the positioning pin 21 overlaps at least partially with the second-layer positioning adapter structure and the third-layer positioning adapter structure in the vertical direction. The positioning component limits the lifting frame 4 in the vertically downward direction; that is, the extended positioning pin 21 rests on the positioning surface of the second-layer positioning screw 22 or the positioning surface of the third-layer positioning screw 23 to play a limiting role. The positioning pin 21 on the lifting frame 4 extends and retracts through the limiting telescopic cylinder 20. When the lifting frame 4 is lifted to the second or third layer, the corresponding second-layer positioning screw 22 and third-layer positioning screw 23 are used as references, and gravity is used to accurately position the lifting frame 4 in the vertical direction to ensure that the upper surface of the trolley track 36 is at the same height as the upper surface of the kiln mouth steel rail of the steam curing station.

[0105] When the output end of the limit telescopic cylinder 20 is reset, the retracted positioning pin 21 disengages from the second-layer positioning screw 22 or the third-layer positioning screw 23. The positioning pin 21 does not overlap with the second-layer positioning adapter structure or the third-layer positioning adapter structure in the vertical direction, and the positioning component releases the limit on the lifting frame 4.

[0106] like Figure 10 As shown, the positioning telescopic cylinder 39 is mounted on the support frame. The output end of the positioning telescopic cylinder 39 extends and retracts in the vertical direction, and a pin 37 is fixed to the output end of the positioning telescopic cylinder 39. When the positioning telescopic cylinder 39 is in the output position, the pin 37 is inserted into the steam curing station positioning hole 38 set on the edge of the kiln opening to achieve accurate positioning of the track plate transport device. When the positioning telescopic cylinder 39 is reset, the pin 37 is dislodged from the steam curing station positioning hole 38.

[0107] The working process of the steam curing system in this application is as follows:

[0108] 1. The mobile motor 9 drives the walking wheel 10, which in turn moves the track plate transport device to the side of the first row of steam curing stations. The positioning telescopic cylinder 39 drives the pin 37 to insert into the steam curing station positioning hole 38 set at the edge of the hole of the continuous kiln opening, so as to achieve precise positioning.

[0109] 2. The winch 15 drives the lifting frame 4 to lift, and at the same time the positioning pin 21 retracts. When the lifting is completed, the positioning pin 21 is 200 mm below the second layer positioning screw 22 in the vertical direction. The winch 15 stops and the clamping arm drive mechanism drives the clamping arm 6 to open.

[0110] 3. The lifting frame 4 descends under the action of gravity, and when the positioning pin 21 is 2500 mm below the second-layer positioning screw 22 in the vertical direction, the winch 15 stops, and the clamping arm drive mechanism drives the clamping arm 6 to close. At this time, the track plate trolley 5, the track plate mold 40, and the pallet 34 have been supported.

[0111] 4. The winch 15 drives the lifting frame 4 to rise until the positioning pin 21 is 200 mm above the positioning surface of the second-layer positioning screw 22 in the vertical direction. The winch 15 then stops, and the limit telescopic cylinder 20 drives the positioning pin 21 to extend. Under the action of gravity, the lifting frame 4 descends until the positioning pin 21 is in contact with the positioning surface of the second-layer positioning screw 22. The winch 15 then stops, completing the accurate positioning of the lifting frame 4 for the second-layer steam curing station. Figure 9 and Figure 10 As shown.

[0112] 5. The slider telescopic cylinder 18 pushes the slider 27 and the insertion rod 17 on the slider 27, and through the insertion rod 17, pushes the track trolley 5, track mold 40 and pallet 34, so that the trolley track 36 on the pallet 34 is connected with the steel rail of the steam curing station and the height is consistent, thus completing the horizontal advancement of the track trolley 5, track mold 40 and pallet 34.

[0113] 6. The track trolley 5 is moved to the predetermined steam curing position by the trolley translation device, and the insertion rod 17 pulls the tray 34 to reset.

[0114] 7. The winch 15 drives the lifting frame 4 to rise until the positioning pin 21 is 200 mm above the positioning surface of the second-layer positioning screw 22 in the vertical direction, at which point the winch 15 stops. After the positioning pin 21 retracts, the lifting frame 4 descends under the drive of gravity until the positioning pin 21 is 2500 mm below the positioning surface of the second-layer positioning screw 22 in the vertical direction, at which point the winch 15 stops, and the clamping arm drive mechanism drives the clamping arm 6 to open. The winch 15 drives the lifting frame 4 to rise 900 mm and then stops, at which point the clamping arm drive mechanism drives the clamping arm 6 to close.

[0115] 8. The winch 15 drives the lifting frame 4 to lift until the positioning pin 21 is 200 mm below the positioning surface of the second-layer positioning screw 22 in the vertical direction. The winch 15 then stops. This completes one work cycle of lifting the track trolley 5 and the track trolley mold 40 and advancing them to the second-layer steam curing station. The work cycle of lifting the track trolley 5 and the track trolley mold 40 to advance them to the second-layer steam curing station is the same and will not be described again.

[0116] The above steps describe the working process of one of the track slab transport devices. The following steps describe the working process of the other track slab transport device.

[0117] 9. The mobile motor 9 drives the walking wheel 10 to walk to the side of the first row of steam curing stations. The positioning telescopic cylinder 39 drives the pin 37 to insert into the steam curing station positioning hole 38 set at the edge of the hole of the continuous kiln opening to achieve precise positioning.

[0118] 10. The winch 15 drives the lifting frame 4 to rise until the positioning pin 21 is 200 mm above the positioning surface of the second-layer positioning screw 22 in the vertical direction. The winch 15 stops, and the limit telescopic cylinder 20 drives the positioning pin 21 to extend. The lifting frame 4 then descends under the action of gravity until the positioning pin 21 is in contact with the positioning surface of the second-layer positioning screw 22. The winch 15 stops.

[0119] 11. The slider telescopic cylinder 18 pushes the slider 27 and the insertion rod 17 on the slider 27, and pushes the tray 34 and the track trolley 5 through the insertion rod 17, so that the trolley track 36 on the tray 34 is connected with the steel rail of the steam curing station and the height is consistent, thus completing the horizontal advancement of the track trolley 5 and the tray 34.

[0120] 12. The track trolley 5 is moved from the steam curing station to the tray 34 by the trolley translation device, and the slider telescopic cylinder 18 pulls the tray 34 back to its original position through the plug rod 17.

[0121] 13. The winch 15 drives the lifting frame 4 to rise until the positioning pin 21 is 200 mm above the positioning surface of the second-layer positioning screw 22 in the vertical direction. The winch 15 then stops, and after the positioning pin 21 retracts, the lifting frame 4 descends under gravity until the positioning pin 21 is 2500 mm below the positioning surface of the second-layer positioning screw 22 in the vertical direction. The winch 15 then stops, the clamping arm 6 opens, and the lifting frame 4 rises 900 mm. The clamping arm drive mechanism drives the clamping arm 6 to open. After the winch 15 drives the lifting frame 4 to rise 900 mm, it stops, and the clamping arm drive mechanism drives the clamping arm 6 to close.

[0122] 14. The winch 15 drives the lifting frame 4 to rise until the positioning pin 21 is 200 mm below the positioning surface of the second-layer positioning screw 22 in the vertical direction, and then the winch 15 stops.

[0123] This completes one work cycle of pulling the track trolley 5 and track trolley mold 40 out of the second steam curing station. The work cycle of pulling the track trolley 5 and track trolley mold 40 out of the third steam curing station is the same and will not be described again.

[0124] 15. Reverse the power unit, reset the chain, and prepare for the steam curing procedure of the next track plate.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
