Description

Technical Field

[0001] This invention relates to the technical field of prestressed construction equipment for bridge engineering, and in particular to a prestressed corrugated pipe preparation vehicle, a prestressed corrugated pipe preparation vehicle assembly, and their usage method. Background Technology

[0002] Prestressed corrugated pipes are key duct-forming materials in post-tensioned prestressed concrete structures. In precast components such as T-beams and continuous beams of highway and railway bridges, their function is to provide pre-reserved channels for prestressed steel strands. During construction, the corrugated pipes are installed in the reinforcement cage of the bottom web of the T-beam according to the design coordinates. After the concrete is poured and reaches the design strength, the prestressed steel strands are threaded into the corrugated pipe channels. Finally, tensioning and grouting are carried out to give the concrete component prestress, thereby significantly improving the structure's load-bearing capacity and crack resistance.

[0003] Currently, the construction process for prestressed corrugated pipes in T-beams typically involves the following steps: after being produced by pipe-making equipment, the corrugated pipes are stacked on the ground or on temporary supports. Then, manual labor, in conjunction with lifting equipment, lifts the corrugated pipes to the T-beam reinforcement cage, where they are installed and fixed according to the design coordinates. After the concrete is poured and cured to reach its strength, the steel strands are threaded into the formwork at a separate threading station. The entire construction process involves multiple stages, including receiving and storing the corrugated pipes, threading the strands, and transporting them into the formwork, all completed in sections at different work stations by different equipment and manual labor.

[0004] However, the existing construction methods have the following technical problems: Firstly, there is a lack of dedicated mobile platforms for receiving and transporting corrugated pipes. After being produced by the pipe-making equipment, corrugated pipes are usually stacked on the ground or on temporary supports awaiting subsequent installation. There is a lack of dedicated mobile platforms that can directly receive and stably support the finished corrugated pipes produced by the pipe-making equipment. The temporary storage and transport of corrugated pipes mostly rely on manual handling or lifting equipment, which is not only inefficient but also makes the pipes susceptible to damage during multiple transports, affecting the quality of the pore formation.

[0005] Secondly, the separate installation and strand threading processes of corrugated pipes affect construction efficiency. In existing T-beam construction, corrugated pipe installation and positioning are usually completed during the rebar tying stage, fixing the corrugated pipes to the rebar cage according to the design coordinates. However, strand threading can only be carried out after the concrete has been poured and cured to reach its strength. This process completely separates the corrugated pipe installation and strand threading operations in time and space, making it impossible to complete the strand threading operation before the corrugated pipes are placed in the rebar cage, resulting in a long overall construction period. If the strand threading process could be moved forward, completed before the corrugated pipes are placed in the formwork, parallel operations could be achieved, effectively shortening the overall construction period. However, there is currently a lack of equipment to support this operation mode.

[0006] Third, there is a lack of flexible expansion solutions for preparing corrugated pipes of different lengths. Due to limitations in production processes and transportation conditions, the maximum length of a single corrugated pipe section is limited, while T-beams come in various lengths, requiring different lengths of corrugated pipes for different T-beams. Single-length preparation equipment is insufficient to meet the needs of various working conditions. Current technology lacks preparation equipment that can flexibly expand according to the production length of corrugated pipes, and there is a lack of modular design for preparing corrugated pipes of multiple lengths, resulting in insufficient adaptability to construction.

[0025] The present invention also provides a method for using a prestressed corrugated pipe material preparation vehicle, which, when used as described above, includes the following steps: S1. Control the prestressed corrugated pipe material preparation vehicle group to move downstream of the prestressed corrugated pipe manufacturing equipment and pick up the cut prestressed corrugated pipe. S2. The prestressed corrugated pipe preparation vehicle group moves the prestressed corrugated pipe to the position for threading the steel strands, and completes the threading process of the steel strands of the prestressed corrugated pipe on the vehicle group. S3. After completing the threading of the steel strands in the prestressed corrugated pipe, move to the bottom web reinforcement cage where the prestressed corrugated pipe needs to be threaded. S4. Adjust the height of the prestressed corrugated pipe through which the steel strands are threaded, and deliver the prestressed corrugated pipe into the bottom web reinforcement cage. S5. Repeat steps S2 to S5 to complete the prestressed corrugated pipe threading process for the bottom web reinforcement cage.

[0026] The beneficial effects of this invention are: This invention uses a mobile walking component to drive a material preparation vehicle to the downstream of the prestressed corrugated pipe. The feeding component on the material preparation vehicle receives the corrugated pipe produced by the upstream pipe-making equipment and provides stable support. The corrugated pipe is then transferred to a transfer and distribution component to receive the incoming material from upstream, assist in completing the threading process, and temporarily store the threaded corrugated pipe. Then, the pipes are separated and transported one by one to the lifting component. After the material preparation vehicle moves to the predetermined position of the bottom web reinforcement cage of the T-beam, the lifting component lifts the corrugated pipe to the predetermined height and transports it into the reinforcement cage. This realizes the integrated operation of the entire process of corrugated pipe from production and reception, support and storage, threading operation to delivery into the mold. It integrates the original independent operations scattered in different work positions and different processes into the same mobile platform, with compact process connection and effectively shortening the construction cycle. The modular design, which combines a driven material preparation vehicle and a driven material preparation vehicle, allows for the addition of one or more driven material preparation vehicles to both ends of the driven material preparation vehicle, depending on the fabrication length of the prestressed corrugated pipe. The driven and driven material preparation vehicles are then connected by a connecting component to form a material preparation vehicle group. This adapts to the construction needs of corrugated pipes for T-beams of different lengths, improves the equipment's versatility and adaptability to different working conditions, and reduces the cost of repeated equipment investment.

[0056] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0057] The following is combined with Figures 1 to 22 This invention provides a detailed description of a prestressed corrugated pipe preparation vehicle, a prestressed corrugated pipe preparation vehicle assembly, and their usage method.

[0058] This invention provides a prestressed corrugated pipe preparation cart, such as... Figures 1 to 21 As shown, it includes: a base frame 1, a feeding assembly 2, a transfer and distribution assembly 4, a lifting assembly 3, a moving and traveling assembly 5, and a control unit 9.

[0059] Specifically, multiple gantry frames 11 are mounted on the base frame 1. A feeding assembly 2 is located on top of the gantry frames 11 and is used to receive the manufactured prestressed corrugated pipes. A transfer and distribution assembly 4 is located on one side of the inner wall of the gantry frames 11, below the feeding assembly 2, and is used to receive upstream material, assist in the threading process, temporarily store and buffer the threaded corrugated pipes, and then separate and transport them one by one to downstream equipment. A lifting assembly 3 is movably mounted on the other side of the inner wall of the gantry frames 11 and is used to receive and transport the prestressed corrugated pipes. A moving and traveling assembly 5 is mounted on the base frame 1 and is used to move along the laid track. A control unit 9 is also mounted on the base frame 1. In a specific implementation, the feeding assembly 2 and the lifting assembly 3 are further electrically connected to the control unit 9 to control the timing of each assembly's actions.

[0060] In the embodiments of this application, such as Figure 3 and Figure 4 As shown, the feeding assembly 2 includes: a first feeding baffle 21, a second feeding baffle 22, and a first linear drive unit 23.

[0061] Specifically, the first feed baffle 21 is installed on the lower side of the top of the gantry frame 11, and the second feed baffle 22 is hinged to the lower side of the top of the gantry frame 11. The first feed baffle 21 and the second feed baffle 22 together form a guide trough 221 for guiding and receiving the prestressed corrugated pipe. A first linear drive unit 23 is rotatably connected to the lower side of the top of each gantry frame 11. The output end of the first linear drive unit 23 is hinged to one side of the second feed baffle 22, and multiple connecting holes 24 are opened on the opposite sides of the first feed baffle 21 and the second feed baffle 22.

[0062] It should be noted that the location and number of the connecting holes 24 in this application are not specifically limited; they can be any location and number that meets the requirement of connecting to the first feed baffle 21 and the second feed baffle 22 of another material preparation vehicle via matching connecting plates and bolts. In specific implementation, such as... Figure 3 As shown, the connecting holes 24 can be selectively opened at the two ends of the opposite sides of the first feed baffle 21 and the second feed baffle 22, and two sets are opened, with three vertically distributed in each set.

[0063] It should also be noted that the structural form of the first linear drive unit 23 in this application is not specifically limited, and it can be any structural form that satisfies the requirement of driving the second feed baffle 22 to deflect and perform opening and closing actions. In specific implementation, such as Figure 3 As shown, the first linear drive unit 23 can be selectively configured as a thin cylinder, and operated synchronously to cause the output end to extend or retract synchronously. Alternatively, the first linear drive unit 23 can be selectively configured as a miniature electric cylinder.

[0064] In this application, by moving the material preparation vehicle downstream of the prestressed corrugated pipe manufacturing equipment, the movement path of the manufactured prestressed corrugated pipe corresponds to the guide trough 221. After the prestressed corrugated pipe is manufactured, it moves axially between the two first feed baffles 21 and the second feed baffle 22. The guide trough 221 guides the prestressed corrugated pipe, and the height is also corresponding, so that one end of the prestressed corrugated pipe is supported during manufacturing to prevent it from bending downward under gravity. After the prestressed corrugated pipe is manufactured, it is cut off and the whole pipe falls into the guide trough 221. At this time, the output ends of each cylinder retract simultaneously, causing the second feed baffle 22 to rotate in a direction away from the first feed baffle 21, thereby separating the second feed baffle 22 and the first feed baffle 21, opening the bottom of the V-shaped guide trough 221, and allowing the prestressed corrugated pipe to slide out of the guide trough 221 and fall into the temporary storage area 41. After the prestressed corrugated pipe is transferred to the temporary storage area 41, the output ends of each cylinder are simultaneously pushed out, thereby pushing the second feed baffle 22 to rotate to one side relative to the first feed baffle 21. The limit output distance of the output end of the first linear drive unit 23 causes the second feed baffle 22 and the first feed baffle 21 to close together, forming the guide trough 221 to continue to receive the next section of prestressed corrugated pipe.

[0065] In the embodiments of this application, such as Figures 9 to 16 As shown, the transfer and distribution assembly 4 includes: a temporary storage area 41, a first lifting part 42, a lifting end plate 43, an unloading unit 44, a storage area 45, and a splitting unit 46.

[0066] Specifically, a temporary storage area 41 is located inside each gantry frame 11 and directly below the discharge direction of the prestressed corrugated pipe. The temporary storage area 41 is a vertical through-slot structure with an open top, used to accommodate the prestressed corrugated pipe. A first lifting section 42 is installed vertically on one side of the gantry frame 11 and corresponds to the temporary storage area 41, with its output end facing upwards, used to lift or lower the prestressed corrugated pipe in the temporary storage area 41. A lifting end plate 43 is installed on the top of the output end of the first lifting section 42, used to catch the falling prestressed corrugated pipe. Unloading units 44 are installed on the lifting end plate 43 and the gantry frame 11 respectively, used to unload the prestressed corrugated pipe from the temporary storage area 41. A storage area 45 is located below the top of the gantry frame 11 and communicates with the opening at the top of the temporary storage area 41, used to store the unloaded prestressed corrugated pipe. The splitting unit 46 is installed on both sides near the discharge port of the storage area 45, and is used to separate individual prestressed corrugated pipes from the storage area 45 one by one and let them flow out.

[0067] In specific implementation, the first lifting part 42, the unloading unit 44 and the splitting unit 46 are further electrically connected to the control unit 9 to control the working status of the first lifting part 42, the unloading unit 44 and the splitting unit 46.

[0068] In specific implementation, such as Figure 14 As shown, the travel distance of the first lifting part 42 corresponds to the temporary storage area 41. When the output end of the first lifting part 42 is in the extreme ejection state, the prestressed corrugated pipe is ejected from the temporary storage area 41. When the output end of the first lifting part 42 is in the lowest retraction state, the prestressed corrugated pipe is lowered to the lowest position of the temporary storage area 41.

[0069] It should be noted that the structural form of the first lifting section 42 in this application is not specifically limited; it can be any structural form that meets the requirements for raising and lowering the prestressed corrugated pipe and bearing the weight of the steel strand bundle. In specific implementation, such as... Figure 10 As shown, the first lifting section 42 can be selectively configured as a lever-type standard cylinder, with each lever-type standard cylinder arranged to operate synchronously so that the telescopic rods extend or retract simultaneously. Alternatively, the first lifting section 42 can be selectively configured as a hydraulic cylinder or an electric cylinder.

[0070] As some preferred embodiments of this application, such as Figure 13 As shown, the temporary storage area 41 consists of a vertical beam 411 installed on one side of the inner wall of each gantry frame 11, and the gap between the vertical beam 411 and the gantry frame 11. In a specific implementation, intermediate connecting rods are further fixedly connected to the vertical beam 411 and one side of the inner wall of the gantry frame 11 near the bottom and middle positions, respectively.

[0071] In this application, the output ends of each first lifting part 42 are simultaneously pushed out and retracted by the control unit 9 to raise and lower the prestressed corrugated pipe. When lowering, the steel strand bundle is inserted into the prestressed corrugated pipe. After the insertion is completed, the prestressed corrugated pipe with the steel strand bundle inserted is raised and then transferred to the storage area 45 by the unloading unit 44, so that the prestressed corrugated pipe with the steel strand bundle inserted is stored in the storage area 45. The unloading of the prestressed corrugated pipe in the storage area 45 is controlled by the splitting unit 46 to control the number of prestressed corrugated pipes discharged.

[0072] As some preferred embodiments of this application, such as Figures 10 to 16 As shown, the unloading unit 44 includes: a tilting pallet 441, a double connecting rod 443, a tension spring 444, a follower 445, and a second linear drive unit 446.

[0073] Specifically, the tilting pallet 441 is hinged to the top of the lifting end plate 43, and the top of the tilting pallet 441 is provided with a material drop trough 442 for placing prestressed corrugated pipes. A double-link member 443 is connected between the other end of the tilting pallet 441 and the lifting end plate 43. The two links of the double-link member 443 can rotate relative to the tilting pallet 441 and the lifting end plate 43 respectively. The double-link member 443 can be folded and unfolded so that the tilting pallet 441 can be tilted towards the temporary storage area 41. A tension spring 444 is connected between one side of the two links of the double-link member 443 to reset the two links of the double-link member 443 after unfolding. A driven member 445 is provided at the hinge point of the two links of the double-link member 443. The second linear drive unit 446 is installed on one side of the gantry frame 11 and is inclined toward the opening side at the top of the temporary storage area 41. A pusher plate 447 is detachably installed on the output end of the second linear drive unit 446 for pushing the follower 445 to unfold the double connecting rod 443.

[0074] In a specific implementation, the second linear drive unit 446 is further electrically connected to the control unit 9 to control the output end of the second linear drive unit 446 to extend and retract.

[0075] In specific implementation, such as Figure 11 and 12 As shown, the connecting rod rotatably connected to the lifting end plate 43 in the double connecting rod 443 further has a stop 4431 on one side. The stop 4431 extends toward the lifting end plate 43 and supports the double connecting rod 443 when it abuts against the lifting end plate 43 to bear the weight of the steel strand.

[0076] It should be noted that the structural form of the material discharge chute 442 in this application is not specifically limited; it can be any structural form that meets the requirements of receiving the prestressed corrugated pipe, preventing the prestressed corrugated pipe from slipping off the flipping pallet 441, and preventing it from sliding out when the flipping pallet 441 is flipped. In specific implementation, such as Figure 11As shown, the material chute 442 can be selectively designed as an inverted trapezoidal structure, allowing the prestressed corrugated pipe to fall into the inverted trapezoidal flipping tray 441, and slide out along one inclined side of the inverted trapezoidal structure during flipping. As a possible alternative implementation, such as... Figure 12 As shown, the material discharge chute 442 can also be optionally made into a V-shaped structure.

[0077] It should also be noted that the structural form of the follower 445 in this application is not specifically limited; it can be any structural form that meets the sliding friction requirements with the pusher plate 447. In specific implementations, such as... Figure 11 As shown, the driven member 445 can be selectively made into a rotary bearing. As a possible alternative implementation, such as... Figure 12 As shown, the driven member 445 can also be optionally a rotating drum or roller.

[0078] It should also be noted that the structural form of the second linear drive unit 446 in this application is not specifically limited; it can be any structural form that meets the requirement of driving the flipping pallet 441 to move linearly and reciprocally. In specific implementations, such as... Figure 13 As shown, the second linear drive unit 446 can be selectively configured as a double cylinder, with each double cylinder arranged to operate synchronously to synchronously control the output end of each double cylinder to extend and retract. As an alternative implementation, the second linear drive unit 446 can also be selectively configured as a three-axis cylinder or a servo electric cylinder (not shown in the figure).

[0079] It should also be noted that the structural form of the pusher plate 447 in this application is not specifically limited; it can be any structural form that satisfies the requirement of pushing the driven member 445 to unfold the double-link member 443. In specific implementation, such as... Figure 15 As shown, the pusher plate 447 can optionally have an arcuate convex surface on one side relative to the follower 445, which facilitates pushing the follower 445 to one side. As an alternative implementation, such as... Figure 16 As shown, the pusher plate 447 may optionally have a semi-circular protrusion on one side relative to the follower 445.

[0080] In this application, by controlling the piston rod of the first lifting part 42 to push out, the lifting end plate 43 is raised to the top of the temporary storage area 41, and the prestressed corrugated pipe falls into the inverted trapezoidal drop trough 442. Under the action of the inverted trapezoidal structure, the prestressed corrugated pipe is limited to prevent it from sliding out of the drop trough 442. Then, the piston rod of the second linear drive part 446 is controlled to retract, so that the prestressed corrugated pipe is lowered to the threading position, and the steel strand bundle is threaded through the prestressed corrugated pipe. The prestressed corrugated pipe with the steel strand bundle threaded through it is then raised to the top of the temporary storage area 41 again. Then, the output end of the second linear drive unit 446 pushes out, driving the pusher plate 447 to move towards the rotating bearing. The arc-shaped convex surface engages with the driven member 445, causing the driven member 445 to roll on the pusher plate 447, causing the double connecting rod 443 to unfold. The unfolding of the double connecting rod 443 causes the tension spring 444 to stretch and store energy, pushing the flipping tray 441 to deflect towards the storage area 45. The prestressed corrugated pipe slides along the inclined surface of the inverted trapezoidal drop chute 442 towards the storage area 45. The prestressed corrugated pipe is transferred to the storage area 45 to await distribution. Then, the output end of the second linear drive unit 446 is controlled to retract back to its original position, and the tension spring 444 releases its elastic force to pull the two connecting rods of the double connecting rod 443 to fold up, ready to receive the next prestressed corrugated pipe.

[0081] Furthermore, such as Figure 11 and 13 As shown, each gantry 11 is equipped with a guide mechanism on one side for guiding the lifting end plate 43, so as to make the lifting end plate 43 rise and fall smoothly. In specific implementation, the guide mechanism is further equipped with a guide rod 421, and each lifting end plate 43 is equipped with a linear bearing 431. Each lifting end plate 43 is slidably connected to the corresponding guide rod 421 through the linear bearing 431.

[0082] In this application, the lifting end plate 43 moves along the outside of the guide rod 421 during lifting and lowering. The sliding friction between the linear bearing 431 and the guide rod 421 makes the movement smoother and avoids jamming, thereby guiding the lifting end plate 43 and making the lifting end plate 43 rise and fall smoothly.

[0083] As some preferred embodiments of this application, such as Figure 13 and 14 As shown, the storage area 45 includes: a first guide groove plate 451, a second guide groove plate 452, and a storage groove 453.

[0084] Specifically, the first guide plate 451 is installed on the lower side of the top of the gantry frame 11. The second guide plate 452 is installed on the side of the upright beam 411 opposite to the first guide plate 451. An S-shaped storage trough 453 is formed between the two opposite sides of the first guide plate 451 and the second guide plate 452. In a specific implementation, the inlet at the top of the storage trough 453 is further oriented upward toward the open opening at the top of the temporary storage area 41, and its outlet is oriented toward the side away from the temporary storage area 41.

[0085] In this application, the prestressed corrugated pipe after being threaded is removed from the temporary storage area 41, slides into the inclined surface of the entrance at the top of the storage trough 453, and then slides along the slope, passing through the four bends of the S-shaped storage trough 453 in sequence. This buffers the prestressed corrugated pipe, prevents it from falling from a high vertical height, and makes the prestressed corrugated pipe more intact. The prestressed corrugated pipe is temporarily stored in the storage trough 453, waiting to be transferred to the lifting assembly 3.

[0086] As some preferred embodiments of this application, such as Figure 13 and 14 As shown, the splitting unit 46 includes a third linear drive unit 461 and a fourth linear drive unit 463.

[0087] Specifically, the third linear drive unit 461 is installed on one side of the upright beam 411 and is arranged perpendicular to the inclined surface of the outlet of the storage tank 453. A baffle plate 462 is detachably installed on the output end of the third linear drive unit 461 to control the number of prestressed corrugated pipes discharged from the storage tank 453. The fourth linear drive unit 463 is rotatably connected to the other side of the upright beam 411. A tilting arm 464 is rotatably connected to one end of the output end of the fourth linear drive unit 463, and the tilting arm 464 is rotatably connected to one side of the upright beam 411 to prevent the prestressed corrugated pipes from sliding out of the outlet of the storage tank 453.

[0088] In a specific implementation, the third linear drive unit 461 and the fourth linear drive unit 463 are further electrically connected to the control unit 9 to control the output ends of the third linear drive unit 461 and the fourth linear drive unit 463 to extend and retract.

[0089] In specific implementation, such as Figure 13 As shown, a triangular baffle is further provided at the middle of the top of the baffle plate 462. The two sides of the triangular baffle are arc-shaped to accommodate the gap between two adjacent prestressed corrugated pipes.

[0090] It should be noted that the structural form of the third linear drive unit 461 in this application is not specifically limited, and it can be any structural form that meets the requirement of providing linear reciprocating movement. In specific implementation, such as Figure 13 As shown, the third linear drive unit 461 can be selectively configured as a double cylinder, with each double cylinder arranged to operate synchronously to synchronously control the output end of each double cylinder to extend and retract. As an alternative implementation, the second linear drive unit 446 can also be selectively configured as a three-axis cylinder or a servo electric cylinder.

[0091] It should also be noted that the structural form of the fourth linear drive unit 463 in this application is not specifically limited, and it can be any structural form that meets the requirement of providing linear reciprocating movement. In specific implementation, such as Figure 14As shown, the third linear drive unit 461 can be selectively configured as a single-axis cylinder, with each single-axis cylinder arranged to operate synchronously to synchronously control the output end of each single-axis cylinder to extend and retract. Alternatively, the second linear drive unit 446 can be selectively configured as a hydraulic cylinder or a servo electric cylinder.

[0092] In this application, the output end of the third linear drive unit 461 is in the ejection state. At this time, the tilting arm 464 is located at the outlet of the storage tank 453. The prestressed corrugated pipe is blocked in the tilting arm 464, and the output end of the third linear drive unit 461 is also in the ejection state. At this time, the baffle part on the baffle plate 462 is located between the first and second prestressed corrugated pipes at the lower position, so that the second prestressed corrugated pipe moves towards the outlet of the storage tank 453. During unloading, first control the lifting assembly 3 to rise to the outlet position of the storage tank 453, then control the output end of the single-shaft cylinder to retract, driving the tilting arm 464 to deflect counterclockwise, so that the first prestressed corrugated pipe moves out of the storage tank 453 and slides along the inclined surface of the tilting arm 464 onto the lifting assembly 3. After unloading is completed, the output end of the single-axis cylinder is controlled to push out, causing the tilting arm 464 to return to its original position and block the outlet of the storage tank 453. Then, the output end of the double cylinder retracts, causing the second pipe to slide to the outlet of the storage tank 453. Subsequently, the output end of the double cylinder pushes out again, causing the baffle plate 462 to return to its initial position and continue to block the next prestressed corrugated pipe, thereby controlling the number of prestressed corrugated pipes unloaded.

[0093] In the embodiments of this application, such as Figures 5 to 8 As shown, the lifting assembly 3 includes: a lifting frame 31, a baffle plate 32, a receiving plate 33, a conveying assembly 34, and a vertical lifting mechanism 35.

[0094] Specifically, the lifting frame 31 is slidably connected to the other side of the inner wall of multiple gantry frames 11 via ball-bearing linear guides, for smooth lifting and lowering along one side of the inner wall of the gantry frames 11. A baffle plate 32 is installed on one side of the top of the lifting frame 31 to limit the rolling range of the prestressed corrugated pipe. A receiving plate 33 is installed on the top of the lifting frame 31 and is symmetrically arranged with the baffle plate 32; the top of the receiving plate 33 has an upwardly inclined slope. A conveying assembly 34 is disposed on the lifting frame 31 for axially moving the prestressed corrugated pipe. A vertical lifting mechanism 35 is disposed on the lifting frame 31 and connected to the other side of the inner wall of the multiple gantry frames 11 for driving the lifting frame 31 to lift and lower.

[0095] In specific implementation, the conveying component 34 and the vertical lifting mechanism 35 are further electrically connected to the control unit 9, and the working status of the vertical lifting mechanism 35 and the control unit 9 is controlled by the control unit 9.

[0096] As some preferred embodiments of this application, such as Figure 6 and Figure 8 As shown, the conveying assembly 34 includes: a plurality of rollers 341 and a first drive motor 342.

[0097] Specifically, several rollers 341 are rotatably connected to the inner walls of opposite sides of the lifting frame 31 near the top, and each roller 341 extends upward to support the prestressed corrugated pipe. A first drive motor 342 is mounted on the lifting frame 31 to drive the rollers 341 to roll synchronously, so as to transport the prestressed corrugated pipe axially.

[0098] Furthermore, each roller 341 has a double-row sprocket 343 installed at one end of its rotating shaft. Two adjacent double-row sprockets 343 are connected in series by a first chain 344. A drive sprocket 345 is fixedly installed at one end of the drive shaft of the first drive motor 342. A second chain 346 connects the drive sprocket 345 to one of the double-row sprockets 343 located at the end.

[0099] In specific implementation, the first drive motor 342 is further made into a speed-regulating and geared motor to adjust the rotational speed of the support roller 341. A common DC or AC motor is used, paired with a PWM controller or frequency converter to meet the needs of production line speed adjustment, process changes, etc., so as to transport the prestressed corrugated pipe with steel strand bundles.

[0100] In this application, the first drive motor 342 is started by the control unit 9. The drive shaft of the first drive motor 342 drives the drive sprocket 345 to rotate. The second chain 346 drives the double-row sprocket 343 to rotate. When the double-row sprocket 343 rotates, the first chain 344 drives the other double-row sprockets 343 to rotate, so that several support rollers 341 rotate synchronously. By controlling the forward or reverse direction of the first drive motor 342, the rotation direction of several support rollers 341 is controlled so as to transport the prestressed corrugated pipe axially, which facilitates the feeding of the prestressed corrugated pipe into the web stirrup skeleton.

[0101] As some preferred embodiments of this application, such as Figures 7 to 3 As shown, the vertical lifting mechanism 35 is a rack and pinion linear module, which includes: rack 351, first drive shaft 352, meshing gear 353, servo reduction motor 354, first drive sprocket 355 and second drive sprocket 356.

[0102] Specifically, multiple racks 351 are vertically installed on one side of the inner wall of each gantry frame 11. Multiple first drive shafts 352 are rotatably mounted on the lifting frame 31 via bearing seats. Two opposing first drive shafts 352 are connected by a coupling to achieve synchronous rotation. Meshing gears 353 corresponding to the positions of the racks 351 are installed on the multiple first drive shafts 352. The meshing gears 353 are meshed with the opposing racks 351. A servo reduction motor 354 is fixedly installed on the lifting frame 31 as a power source. A first drive sprocket 355 is installed at one end of the drive shaft of the servo reduction motor 354, and a second drive sprocket 356 is installed in the middle of the first drive shaft 352. The first drive sprocket 355 and the second drive sprocket 356 are connected by chain drive.

[0103] In use, the control unit 9 controls the servo reduction motor 354 to start according to the control command. The servo reduction motor 354 drives the first transmission sprocket 355 to rotate, and transmits the power to the second transmission sprocket 356 through the chain, thereby driving the first transmission shaft 352 to rotate. The first transmission shaft 352 drives the multiple meshing gears 353 on it to rotate. Since the rack 351 is fixed, the meshing gears 353 will move up and down along the rack 351 while rotating, thereby driving the lifting frame 31 to perform a smooth vertical lifting and lowering movement relative to the gantry frame 11.

[0104] In this application, when the lifting frame 31 is raised and lowered, the gear and rack linear module raises the lifting frame 31 to below the outlet of the storage tank 453. The inclined plate is aligned with the outlet of the storage tank 453, so that the prestressed corrugated pipe slides along the inclined plate between the baffle plate 32 and the receiving plate 33. The baffle plate 32 and the receiving plate 33 restrict the prestressed corrugated pipe to prevent it from rolling off the lifting frame 31. The prestressed corrugated pipe falls on several support rollers 341, which lift the prestressed corrugated pipe. The prestressed corrugated pipe is then conveyed axially by the conveying assembly 34.

[0105] It should be noted that the structural form of the vertical lifting mechanism 35 in this application is not specifically limited, and it can be any structural form that meets the load and provides vertical lifting requirements.

[0106] As an alternative implementation, the vertical lifting mechanism 35 can also be selectively configured as a linear motor module. In a specific implementation, the linear motor module is further fixed to the gantry 11 in the vertical direction along the inner wall of one side of the gantry 11. The lifting frame 31 is connected to the gantry 11 via the linear motor module. The linear motor module is electrically connected to the control unit 9 and is controlled by the control unit 9 (not shown in the figure).

[0107] In use, the control unit 9 powers on the linear motor module, and the mover of the linear motor module moves linearly along the stator under the action of the magnetic field, thereby directly driving the lifting frame 31 connected to it to move vertically up and down along the gantry frame 11.

[0108] As an alternative implementation, the vertical lifting mechanism 35 can optionally be a screw-slider module. In a specific implementation, the screw-slider module further includes a drive motor, a screw, a slider adapted to the screw, and a slide rail adapted to the slider. In a specific implementation, the screw is connected to the gantry 11 via a bearing seat along the vertical direction of the gantry 11, the drive motor is connected to the screw drive, and the slider is fixedly connected to the lifting frame 31 (not shown in the figure).

[0109] When in use, when the drive motor is powered, the motor drives the lead screw to rotate. During the rotation of the lead screw, the lifting frame 31 moves along the ball-type linear guide rail through the slider. By controlling the rotation direction of the motor, the lifting frame 31 is controlled to rise or fall.

[0110] In addition to the above-described embodiments, the vertical lifting mechanism 35 may optionally be a drive assembly including a telescopic cylinder (pneumatic telescopic cylinder, hydraulic telescopic cylinder); the specific connection method is a conventional setting in the art and will not be described in detail here.

[0111] As some preferred embodiments of this application, such as Figures 20 to 21 As shown, it also includes a lifting unit 6, which is disposed at both ends of the base frame 1 along its length and is used to lift both ends of the prestressed corrugated pipe. The lifting unit 6 includes: two mounting brackets 61, a second lifting part 62, and a support plate 63.

[0112] Specifically, two mounting brackets 61 are symmetrically arranged at both ends of the base frame 1 along its length. Two second lifting parts 62 are respectively mounted on the two mounting brackets 61, with the output ends of the second lifting parts 62 perpendicular to the base frame 1 and facing upwards. Two support plates 63 are respectively mounted on the top of the output ends of the two second lifting parts 62, and the support plates 63 are provided with placement grooves 631 for placing prestressed corrugated pipes.

[0113] In practice, two linear bearings for guidance are installed on each mounting bracket 61. Guide rods are slidably installed in each of the two linear bearings, and the top ends of the two guide rods are connected to the bottom of the support plate 63 for guidance.

[0114] In practice, each of the second lifting sections 62 is controlled separately to lift the prestressed corrugated pipe section as needed, so that the threading device can pass through the prestressed corrugated pipe.

[0115] It should be noted that the structural form of the support plate 63 in this application is not specifically limited; it can be any structural form capable of supporting the prestressed corrugated pipe. In specific implementation, such as... Figure 20 As shown, the support plate 63 can optionally be two vertical plates, each with an arc-shaped groove to confine the prestressed corrugated pipe. As an alternative implementation, such as... Figure 21 As shown, the tray 63 can also be selectively configured as one, two, three or more vertical trays, and the tray has a V-shaped groove.

[0116] It should also be noted that the structural form of the second lifting part 62 in this application is not specifically limited, and it can be any structural form capable of lifting and lowering the prestressed corrugated pipe. In specific implementations, the second lifting part 62 can be selectively made into a cylinder. As an alternative embodiment, the second lifting part 62 can also be selectively made into a hydraulic cylinder or an electric cylinder.

[0117] In this application, the prestressed corrugated pipe rests on the support plate 63 at the output end of each of the second lifting parts 62. By controlling the piston rod of each of the second lifting parts 62 to push out, one end of the prestressed corrugated pipe is lifted, causing the threading device to slide from the high point to the low point, so that the threading device passes through the prestressed corrugated pipe. After passing through a section, the output end of the second linear drive part 446 that lifted the section is controlled to retract.

[0118] As some preferred embodiments of this application, such as Figures 17 to 18 As shown, the mobile walking assembly 5 includes: multiple pairs of walking wheels 51, multiple second drive shafts 52, multiple reducers 53, a third drive sprocket 54, and a fourth drive sprocket 55.

[0119] Specifically, multiple pairs of traveling wheels 51 are installed at the bottom of the base frame 1 for movement along the matching guide rails 511 arranged in the direction of movement. Multiple second drive shafts 52 are respectively connected between two opposing inner walls on the same side of the bottom of the base frame 1. The opposing ends of the multiple second drive shafts 52 are connected by couplings 521, and the two end-positioned second drive shafts 52 are respectively provided with second connecting flanges 522. Multiple reducers 53 are installed at the bottom of the base frame 1, corresponding to each traveling wheel 51. A transfer sprocket 531 is fixedly installed at one end of the output shaft and one end of the input shaft of each reducer 53. A third drive sprocket 54 is installed on the axle of each traveling wheel 51 on the same side, and a third chain 541 connects the third drive sprocket 54 to one of the transfer sprockets 531. A fourth drive sprocket 55 is fixedly mounted on the second drive shaft 52 and corresponds to the position of the transfer sprocket 531. A fourth chain 551 connects the fourth drive sprocket 55 to the opposing transfer sprocket 531.

[0120] Furthermore, such as Figure 18As shown, a second drive motor 7 is mounted on the base frame 1, and a second drive sprocket 71 is fixed on its drive shaft. A fifth chain 72 is connected between the second drive sprocket 71 and one of the fourth transmission sprockets 55.

[0121] In specific implementation, the second drive motor 7 is further made into a servo geared motor. This servo geared motor is an integrated transmission device composed of a planetary gear reducer and a servo motor, which is used for precise control and powerful output. The servo motor is responsible for providing precise speed and position control, while the planetary gear reducer reduces the high speed of the motor through its internal gear structure, while increasing the output torque by a factor of two to drive the entire vehicle body to move.

[0122] In specific implementation, bearings are further provided on the two opposite inner walls of the bottom frame 1 near the same side. Each bearing is distributed along the same axis, and a spline shaft for transmission is provided in each bearing. Couplings 521 are installed at both ends of the spline shaft, and the second transmission shaft 52 is connected between the rotating shafts of the two opposite couplings 521.

[0123] It should be noted that the structure of the traveling wheel 51 in this application, which is matched with the guide rail, is not specifically limited; it can be any structure that allows it to roll along the guide rail. In specific implementations, such as... Figure 19 As shown, the guide rail can be optionally made of angle iron, and the traveling wheel 51 is a V-shaped roller used in conjunction with the angle iron. As an alternative implementation, the guide rail can also be optionally made of long steel rail, and the traveling wheel 51 can be an H-shaped roller (not shown in the figure) used in conjunction with it.

[0124] In this application, when the prestressed corrugated pipe preparation cart moves, the second drive motor 7 is started, driving the second drive sprocket 71 to rotate. Through the fifth chain 72, the fourth drive sprocket 55 drives one of the second drive shafts 52 to rotate. Through the coupling 521, each second drive shaft 52 rotates synchronously. When the second drive shaft 52 rotates, it drives each fourth drive sprocket 55 to rotate synchronously. After passing through each reducer 53, it is driven by the third chain 541 to drive each third drive sprocket 54 to rotate synchronously, causing each traveling wheel 51 to rotate synchronously, driving it to move along the guide rail. By controlling the rotation direction of the second drive motor 7, the reciprocating movement of the prestressed corrugated pipe preparation cart is controlled.

[0125] The present invention also provides a prestressed corrugated pipe material preparation vehicle assembly, such as... Figures 1 to 22 As shown, it includes: a drive material preparation vehicle 100, a driven material preparation vehicle 200, and a connecting assembly 8.

[0126] Specifically, the structure of the drive material preparation car 100 is the prestressed corrugated pipe material preparation car described above. The structure of the driven material preparation car 200 is the same as the prestressed corrugated pipe material preparation car described above, but the driven material preparation car 200 does not have the second drive motor 7, the second drive sprocket 71, and the fifth chain 72. A connecting assembly 8 is respectively provided on the drive material preparation car 100 and the driven material preparation car 200, for detachably connecting the drive material preparation car 100 and the driven material preparation car 200.
