Description

Technical Field

[0001] This invention relates to the field of track slab production technology, specifically to a production line for a long-faced platform of prestressed concrete track slabs. Background Technology

[0002] Track slabs are slab-shaped components used to support and fix steel rails, distributing the load transmitted by trains through the rails to a base beneath the slab. As my country's high-speed railway construction technology expands globally, higher demands are placed on the quantity and quality of track slabs. High-quality, high-precision track slab production is a crucial aspect of high-speed railway construction technology.

[0003] The production process of track slabs (prestressed track slabs) requires the following steps: First, the formwork must be cleaned to ensure the appearance quality of the concrete. After cleaning the formwork, a layer of release agent is sprayed evenly. Second, the embedded sleeves are installed and lifted, the reinforcing cage is placed and threaded. After threading, the reinforcing bars are initially tensioned, and then spacers are placed before tensioning. After tensioning, insulation testing is performed. Finally, concrete is poured into the mold and vibrated. After steam curing, the tension is released, the tension is removed, and the mold is demolded. Then, water bath curing is performed.

[0004] Existing track slab production lines are not standardized in layout and have low transfer efficiency. Due to the structural limitations of the production molds, transfer is generally carried out by truss cranes, which results in low work efficiency and poor pressure holding effect of the tensioning system, failing to meet people's needs. Therefore, it is necessary to study a pre-tensioned prestressed concrete track slab long-face platform production line. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a production line for long-faced prestressed concrete track slabs, which effectively solves the problems of poor continuity, low transfer efficiency, and poor pressure holding effect of existing track slab production lines.

[0006] To achieve the above objectives, the technical solution adopted by this invention is: a prestressed concrete track slab long-face platform production line, comprising an assembly station, a steel reinforcement cage and tensioning steel reinforcement placement station, a tensioning station, a joint insulation testing station, a concrete pouring and vibration station, a steam curing station, a demolding and dismantling station, a cleaning station, a turning station, a quality inspection station, a water curing station, a drying station, and a warehousing station; wherein the assembly station, steel reinforcement cage and tensioning steel reinforcement placement station, tensioning station, joint insulation testing station, concrete pouring and vibration station, steam curing station, demolding and dismantling station, and cleaning station are arranged in a ring-shaped area, and the last cleaning station is connected to the first assembly station to form a closed square structure assembly line; a central control room is arranged in the middle area of ​​the closed square structure assembly line; The flipping station obtains the semi-finished track plate from the demolding station, flips it so that its bottom surface is facing up, and sends it to the quality inspection station for quality inspection. After quality inspection, it is sent to the water curing station for curing, and then dried in the drying station before being put into storage. The closed square structure assembly line has a transverse transfer device and a longitudinal transfer device; the transverse transfer device includes a transverse track and a positioning block; the transverse track is arranged on both sides of the workstation, and the transfer vehicle can travel on the transverse track; the positioning block is set on the track and extends or retracts from the track under the drive of the drive structure, thereby restricting the movement of the transfer vehicle; the longitudinal transfer device includes a truss crane, which is arranged longitudinally, and the transfer vehicle is equipped with a lifting seat; the truss crane can move longitudinally, and its lifting device is adapted to the lifting seat.

[0007] Furthermore, the transfer vehicle is equipped with a slot that fits into the combined mold. The combined mold includes a bottom mold, side molds, and a tension rod. The bottom mold and side molds are combined into a sealed structure, with corresponding tension holes on opposite side molds. The tension holes include assembly holes and extension holes. The center of the assembly hole communicates with the extension hole. The tension rod includes a drive rod, a top support sleeve, a drive sleeve, engagement teeth, and a spring. The top support sleeve has an outer cavity and an inner cavity on both sides. The interior of the drive rod is connected to the top support sleeve via a solid structure. The support sleeve is connected to form an interlocking cavity between the solid bodies. The outer cavity and the inner cavity are connected by the evenly spaced interlocking cavities. The inner cavity is adapted to the tensioned steel bar. The interlocking cavity is adapted to the upper part of the interlocking teeth and has an inclined structure. The bottom of the interlocking teeth is connected to the bottom of the interlocking cavity by a spring. A thread is provided on the outside of the outer cavity. The drive sleeve is threaded with the outer cavity and can press down on the upper part of the interlocking teeth, so that the end of the interlocking teeth touches the outside of the interlocking cavity along the inclined surface and locks the tensioned steel bar.

[0008] Furthermore, a pressure-holding component is arranged in the tensioning hole of one of the side molds, and a fixing hole is arranged in the opposite side mold. The pressure-holding component includes a top pressure block and a driving component. The top pressure block is nested at the bottom of the assembly hole, and the driving component is arranged at its rear. A top support slope is provided on the outer side of the top pressure block. The driving component is used to drive the top pressure block to advance or retract towards the center of the assembly hole. The bottom of the top support sleeve is provided with a slope that cooperates with the top support slope. A T-shaped driving part is provided at the end of the driving rod on this side.

[0009] Furthermore, the driving component is a hydraulic cylinder.

[0010] Furthermore, the driving component includes a screw sleeve, a lead screw, a bevel gear set, and a drive shaft; the drive shaft extends to the outside of the side mold, and the inner end of the drive shaft is connected to the lead screw via the bevel gear set; the lead screw is rotatably disposed inside the side mold, and the screw sleeve is threadedly connected to the lead screw and fixed to the top pressure block via a connecting rod.

[0011] Furthermore, the tensioning station includes two adjacent tensioning tables. The bottom of the tensioning table is equipped with a hydraulic lifting rod, which can adjust the height of the tensioning table. A tensioning seat is slidably nested on the tensioning table. The tensioning seat has a T-shaped limiting groove. A tensioning hydraulic cylinder is provided on the rear side of the tensioning seat.

[0012] Furthermore, the transfer vehicle includes a base and wheels; the base is provided with a slot for the combination mold to fit, and the wheels include a power wheel and rollers, with the power wheel located in the middle and a self-drive motor mounted on it.

[0013] Furthermore, the side mold is provided with connecting ear plates on both sides, and the bottom mold is provided with fixing ear plates at the four corners. The connecting ear plates are mated to the two sides of the fixing ear plates and fixed by bolts, so that the side molds are assembled into a sealed mold. Multiple reinforcing bolts are also provided at the bottom of the side mold.

[0014] The beneficial effects of the above technical solution are as follows: In this invention, the production line is a closed ring structure. After the side molds and bottom molds are removed and cleaned, they can be directly transported to the assembly station for assembly. After assembly, a release agent is sprayed on them, and then they enter the steel reinforcement cage and tensioning steel reinforcement placement station by translation and rolling. The steel reinforcement cage and tensioning steel reinforcement are arranged in the combined mold. The length of the tensioning steel reinforcement is designed and it enters from the tensioning hole, while also being reserved in the tensioning hole. After completion, it enters the tensioning station by translation and rolling. At the tensioning station, the tensioning table is raised and lowered, and the tensioning rod enters the tensioning seat. The external strong tensioning hydraulic structure applies pressure to the horizontal and longitudinal tensioning rods to tension the steel reinforcement. Then, the drive component is activated, so that the top pressure block is supported at the bottom of the top support sleeve. Due to the limitation of the inclined plane, the two have a large contact surface. When the external hydraulic pressure is removed, the inclined plane structure can decompose the force. The horizontal force is borne by the drive component, and the vertical force is borne by the rigidity of the structure itself. The two forces jointly bear the reset stress of the tensioning steel reinforcement, resulting in good pressure holding effect.

[0015] After tensioning, the track slabs are moved longitudinally using a truss crane and then moved to the node insulation testing station. After the testing is completed, the track slabs are transported to the concrete pouring and vibration station using a truss crane. Then, they are steam cured and demolded in sequence. After demolding, the removed molds are cleaned and then directly moved to the assembly station. Meanwhile, the semi-finished track slabs go through the flipping, quality inspection, and water curing processes. The various stations work together seamlessly, resulting in high production efficiency.

[0016] Therefore, this invention adopts a reasonable layout and improves the combination mold, so that each station can operate in sequence and in an orderly cycle. The production line layout is reasonable, the transfer efficiency is high, the transfer is convenient, the production cost is reduced, and the level of automated operation of the track plate is improved.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1: This example aims to provide a prestressed concrete track slab long-face platform production line, mainly used for assembly line production of track slabs. In view of the fact that the current transfer method is mostly hoisting and the workstation layout is not standardized, resulting in low production efficiency, this example mainly sorts the assembly line layout.

[0020] In this embodiment, as Figure 1The image shows a production line for a prestressed concrete track slab with a long surface platform. The line includes an assembly station, a steel reinforcement cage and tensioning steel reinforcement placement station, a tensioning station, a joint insulation testing station, a concrete pouring and vibration station, a steam curing station, a demolding and removal station, a cleaning station, a flipping station, a quality inspection station, a water curing station, a drying station, and a warehousing station. The assembly station, steel reinforcement cage and tensioning steel reinforcement placement station, tensioning station, joint insulation testing station, concrete pouring and vibration station, steam curing station, demolding and removal station, and cleaning station are arranged in a circular area. The last cleaning station connects with the first assembly station to form a closed square structure assembly line. A central control room is located in the middle of the closed square structure assembly line. In this embodiment, the process from mold assembly to demolding and cleaning is a closed assembly line, and this assembly line is arranged around the central control room for easy control and transfer.

[0021] The side mold 2 is provided with connecting ear plates 5 on both sides, and the bottom mold 3 is provided with fixing ear plates 4 at the four corners. The connecting ear plates 5 are connected to the two sides of the fixing ear plates 4 and fixed by bolts, so that the side molds are combined into a sealed mold. Multiple reinforcing bolts are also provided at the bottom of the side molds.

[0022] The flipping station retrieves the semi-finished track plate from the demolding station, flips it so that its bottom surface is facing up, and sends it to the quality inspection station for quality inspection. After quality inspection, it is sent to the water curing station for curing, and then to the drying station for drying before being put into storage. In this embodiment, the finished track plate is removed from the circular production line and transferred to another area. The operations in the two areas do not interfere with each other, and the process connection is reasonable.

[0023] In terms of transfer, the closed square structure assembly line in this embodiment has a transverse transfer device and a longitudinal transfer device; wherein the transverse transfer device includes a transverse track 22 and a positioning block 23; the transverse track 22 is arranged on both sides of the workstation, and the transfer vehicle can travel on the transverse track 22; the positioning block 23 is set on the transverse track 22, and extends or retracts from the track under the drive of the drive structure, thereby restricting the movement of the transfer vehicle; in this embodiment, the drive structure is a stepper motor or an electric push rod, which can push the positioning block out or rotate it off the track, and reset it when necessary.

[0024] The longitudinal transfer device includes a truss crane 1, which is arranged longitudinally, and a lifting seat is arranged on the transfer vehicle. The truss crane 1 can move longitudinally, and its lifting device is adapted to the lifting seat. As an improvement to the transfer vehicle, a slot is provided on the transfer vehicle, which is adapted to the combined mold 19. The two are in a locking relationship so that the truss crane can lift the combined mold. The transfer vehicle includes a base 20 and moving wheels 21. The base is provided with a slot adapted to the combined mold, and the moving wheels include a power wheel and rollers. The power wheel is located in the middle and a self-drive motor is provided on it.

[0025] Structurally, the combined mold includes a bottom mold 3, a side mold 2, and a tension rod 7. The bottom mold 3 and the side mold 2 are combined into a sealed combined mold structure. Tensioning holes are correspondingly provided on the opposite side mold 2. The tensioning holes include assembly holes and extension holes. The middle part of the assembly hole is connected to the extension hole, and the reinforcing bar can pass through the assembly hole and the extension hole. In terms of shape, the assembly hole is larger than the extension hole, and the extension hole is basically adapted to the outer diameter of the tensioned reinforcing bar.

[0026] Structurally, the tension rod 7 includes a drive rod 72, a top support sleeve 71, a drive sleeve 76, engagement teeth 75, and a spring 77. The top support sleeve 71 has an outer cavity and an inner cavity 73 on both sides. Structurally, the inner cavity 73 faces into the combined mold, and the outer cavity faces outward from the combined mold. The interior of the drive rod 72 is connected to the top support sleeve through a solid 78. The gap between the solids 78 forms an engagement cavity 74. The outer cavity and the inner cavity are connected through the evenly distributed engagement cavities 74, so that the top support sleeve 71 and the drive rod 72 are an integral structure and can withstand a common load. The engagement teeth structure connects the tensioned steel bar 6 integrally with the top support sleeve. The lower part of the engagement cavity is enlarged, and the upper part is a sloping structure between it and the solid. The upper part of the engagement teeth is the drive part 751, and the lower part is the engagement part 752. The engagement part is provided with a tooth-like structure to increase its friction with the tensioned steel bar.

[0027] The inner cavity is adapted to the tensioning bar 6. When the tensioning rod is installed in the assembly hole, the tensioning bar can be placed in the inner cavity 73, thereby determining the biting point of the biting teeth. Structurally, the biting cavity 74 is adapted to the upper part of the biting teeth 75 and is a sloping structure. The bottom of the biting teeth is connected to the bottom of the biting cavity through a spring. The arrangement direction of the spring 77 is adapted to the sloping structure. When the biting teeth move downward along the biting cavity, the bottom of the biting teeth will compress the spring 77, and after the force disappears, it will reset under the action of the spring 77.

[0028] To drive the bite tooth 75 structure, a thread is provided on the outer side of the outer cavity. The drive sleeve 76 engages with the thread of the outer cavity and can press down on the upper part of the bite tooth 75, so that the end of the bite tooth 75 touches the outside of the bite cavity along the inclined surface and locks the tensioned steel bar. Through the threaded advance and self-locking structure, the bite tooth can be pushed forward, so that the bite tooth can be pushed down along the bite cavity. Due to the limitation of the inclined surface structure, the lower bite head of the bite tooth can enter the inner cavity and lock the tensioned steel bar 6.

[0029] A pressure-holding assembly is also arranged in the tensioning hole of one of the side molds, and a fixing hole is arranged in the opposite side mold. A fixing rod is arranged in the fixing hole, and the structure of the fixing rod is as follows. Figure 4As shown in the figure, its internal structure is similar to that of a tension rod, except that it does not have a pressure-holding component, and the end shapes of its fixed top contact sleeve 81 and fixed drive rod 82 are different. The pressure-holding component includes a top pressure block 9 and a drive component. The bottom of the top pressure block 9 is nested in the assembly hole (suitable for the fitting, with a certain limiting structure), and the drive component is provided at its rear. The outer side of the top pressure block 9 is provided with a top support slope. The drive component is used to drive the top pressure block 9 to advance or retract into the center of the assembly hole. The bottom of the top support sleeve 71 is provided with a slope that cooperates with the top support slope. The end of the drive rod on this side is provided with a T-shaped drive part.

[0030] In this embodiment, the driving component is a hydraulic cylinder 10; the tensioning station includes two adjacent tensioning tables 15, the bottom of the tensioning table 15 is provided with a hydraulic lifting rod, which can adjust the height of the tensioning table, a tensioning seat 17 is slidably nested on the tensioning table 15, a T-shaped limiting groove 18 is provided on the tensioning seat 17, and a tensioning hydraulic cylinder 16 is provided on the rear side of the tensioning seat.

[0031] In this embodiment, after assembly, a release agent is sprayed on, and then the assembly moves into the rebar cage and tensioning rebar placement station by a horizontal rolling motion. The rebar cage and tensioning rebar are arranged in the combined mold, the length of the tensioning rebar is designed, and it enters through the tensioning hole, while also being pre-reserved within the tensioning hole. After completion, it moves into the tensioning station by a horizontal rolling motion. At the tensioning station, the tensioning table is raised and lowered, and the tensioning rod enters the tensioning seat. The external high-pressure hydraulic structure applies pressure to the horizontal and vertical tensioning rods to tension the rebar. Then, the drive component is activated, so that the top pressure block is supported at the bottom of the top support sleeve. Due to the limiting effect of the inclined plane, the two have a large contact surface. When the external hydraulic pressure is removed, the inclined plane structure can decompose the force. The horizontal force is borne by the drive component, and the vertical force is borne by the rigidity of the structure itself. The two forces jointly bear the reset stress of the tensioning rebar, resulting in good pressure holding effect.

[0032] Example 2 further illustrates another structure of the driving component.

[0033] In this embodiment, the driving component includes a threaded sleeve 12, a lead screw 11, a bevel gear set 13, and a drive shaft 14. The drive shaft 14 extends to the outside of the side mold, and the inner end of the drive shaft 14 is connected to the lead screw 11 via the bevel gear set 13. The lead screw 11 is rotatably disposed inside the side mold. The threaded sleeve 12 is threadedly connected to the lead screw 11 and fixed to the top pressure block via a connecting rod. In this embodiment, the threaded sleeve can be pushed forward under the drive of the lead screw through the limiting of the connecting rod. In this example, multiple sets of connecting rods are arranged to improve the contact and resistance to reactive forces.

[0034] As a drive structure for the drive shaft, one drive shaft can be extended outward and docked with the drive structure on the tensioning table. Specifically, the drive motor is propelled by translation. The drive motor is equipped with a spline sleeve, and the drive shaft is equipped with a spline shaft. The two dock to realize the transmission of the structure. Multiple drive shafts are connected by chain and sprocket transmission to realize the driving and propulsion of multiple top pressure blocks. This structure does not need to add drive nodes inside, and the pressure holding and propulsion force is realized by external driving force.

[0035] Example 3 further illustrates the structure of the drive sleeve.

[0036] In this embodiment, threads are arranged on both the inner and outer sides of the drive sleeve. The inner thread is connected to the drive rod, and the outer thread is connected to the inner thread of the outer cavity. The double thread connection can further enhance the connection strength between the drive rod and the top support sleeve.

[0037] Meanwhile, the double-threaded structure provides greater pressure on the interlocking teeth, resulting in a stronger interlocking effect and improving the fixing strength of the tensioned steel bars.
