Description

Technical Field

[0001] This utility model relates to the field of pipe pile production technology, and in particular to a rail flatbed transport device for building pipe piles. Background Technology

[0002] In construction engineering, pipe piles are key components of the foundation structure. They are characterized by their large weight, long length, and easy rolling due to their cylindrical shape. The transportation of pipe piles must take into account safety, efficiency, and the characteristics of the pipe piles themselves to avoid breakage, collision, or displacement during transportation. The transportation efficiency of pipe piles directly affects the construction progress.

[0003] Existing methods for transporting pipe piles mostly rely on stacking them on ordinary flatbed trucks, which lacks flexibility in transportation. Furthermore, the lack of specific fixing structures makes it easy for pipe piles to slide and collide, increasing the difficulty of loading and unloading and potentially damaging the piles. In addition, when the transportation device uses a clamping mechanism to hold the pipe pile mold, it often uses point clamping without safety measures. If the clamping is not tight during transportation, the pipe pile mold containing the pipe pile can easily fall off, threatening the safety of workers and site equipment. Utility Model Content

[0004] This utility model aims to provide a rail-mounted flatbed transport device for building pipe piles, which not only has the characteristics of flexible transportation, but also effectively avoids damage to the pile body during transportation, and prevents the pile body from falling easily, thereby eliminating the safety threat to workers and site equipment.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rail flatbed transport device for building pipe piles, including a main beam, a suspension mechanism fixedly installed on the upper part of the main beam, and a plurality of clamping mechanisms and pile-holding mechanisms fixedly installed on the lower part of the main beam, with the clamping mechanisms and pile-holding mechanisms arranged at intervals.

[0006] By adopting the above technical solution, the clamping mechanism and the pile-holding mechanism are used for dual fixation. The clamping mechanism applies pressure to the outer wall of the pipe pile mold through rigid clamping force, and the pile-holding mechanism holds the outer wall of the pipe pile mold. The two are set at intervals to form multi-point fixation.

[0007] The present invention is further configured such that: the clamping mechanism includes a mounting plate, a first driving component and a clamping unit; the first driving component includes a drive motor fixedly mounted on the mounting plate and a drive wheel fixedly connected to the output shaft of the drive motor; the clamping unit includes a drive component, a driving component and a gripper.

[0008] By adopting the above technical solution, the gripper adopts a "surface contact" clamping method. This surface contact method can significantly disperse pressure and avoid deformation caused by excessive local stress on the pipe pile mold.

[0009] The present invention is further configured as follows: the active component includes a first gear meshing with the active wheel, a connecting rod is fixedly connected to the side of the first gear away from the active wheel, the first gear is rotatably connected to the mounting plate through a first pin, the end of the connecting rod is rotatably connected to the gripper through a second pin, the driving component includes a driving rod disposed below the connecting rod, one end of the driving rod is rotatably connected to the mounting plate through a third pin, and the other end is rotatably connected to the gripper through a fourth pin, and two sets of clamping units are provided, which are symmetrically arranged about the pitch circle center line of the first gear, and the transmission is achieved through the meshing of the two first gears of the two clamping units.

[0010] By adopting the above technical solution, the first gear drives the first gear symmetrical to it to rotate. This symmetrical structure allows the two grippers to move closer to or further away from the center at the same time, ensuring that the clamping force on the outer wall of the pipe pile mold is evenly distributed, and avoiding deformation or displacement of the pipe pile mold due to uneven force on one side.

[0011] A further feature of this invention is that the active component and the driving component are symmetrically provided with auxiliary components via the mounting plate. The auxiliary components include a first auxiliary rod and a second auxiliary rod. One end of the first auxiliary rod is rotatably connected to the mounting plate via a first pin, and the other end is rotatably connected to the gripper via a second pin. One end of the second auxiliary rod is rotatably connected to the mounting plate via a third pin, and the other end is rotatably connected to the gripper via a fourth pin. Two sets of auxiliary components are provided, symmetrically arranged with the pitch circle center line of the first gear as the axis.

[0012] By adopting the above technical solution, the symmetry of the auxiliary component, active component, and driving component complements each other, further ensuring the synchronous movement of the grippers on both sides. Even in high-speed transportation or bumpy environments, the auxiliary component can suppress the asymmetrical movement of the grippers and improve clamping stability.

[0013] The present invention is further configured such that the pile-holding mechanism includes a mounting frame, a second drive assembly, a driven assembly located below the second drive assembly, and holding assemblies located on the front and rear sides of the second drive assembly.

[0014] By adopting the above technical solution, the holding component can be used to fix the pipe pile mold in a ring shape, forming multi-point support. Furthermore, the holding component can automatically adjust the ring radius according to the outer diameter of the pipe pile mold, making it suitable for pipe pile molds of different specifications and improving the versatility of the device.

[0015] The present invention is further configured such that: the mounting frame includes a positioning plate, a left side plate and a right side plate are fixedly mounted on the left and right sides of the positioning plate respectively; the second drive assembly includes a cylinder fixed on the positioning plate; a support plate is fixedly connected to the end of the telescopic shaft of the cylinder; support rods are rotatably connected to the ends of the left and right sides of the support plate; a first drive shaft rotatably connected to the lower ends of the two support rods located on the front side is passed through the lower ends of the two support rods located on the rear side; and a second drive shaft rotatably connected to the lower ends of the two support rods located on the rear side is passed through the lower ends of the two support rods; the first drive shaft and the second drive shaft are arranged opposite to each other.

[0016] By adopting the above technical solution, the cylinder drives the support plate to move up and down, and the support rods on the left and right sides synchronously drive the first active shaft on the front side and the second active shaft on the rear side to move in opposite directions or in opposite directions, so as to realize the synchronous action of the holding units on the front and rear sides, ensuring that the pipe pile mold is always in the center position during transportation and avoiding uneven force caused by displacement.

[0017] The present invention is further configured such that: the holding assembly includes a first holding unit and a second holding unit, both the first holding unit and the second holding unit include a clamping arm and a holding rod, the holding rod is fixedly disposed at the lower end of the clamping arm, the vertical angle between the holding rod and the clamping arm is 90°, the first holding unit and the second holding unit are disposed opposite to each other, the distance between the two clamping arms of the first holding unit is greater than the distance between the two clamping arms of the second holding unit, and the distance between the two clamping arms of the first holding unit is greater than the sum of the widths of the two clamping arms of the second holding unit;

[0018] The two ends of the first drive shaft are rotatably connected to the two clamping arms of the first holding unit, and the two ends of the second drive shaft are rotatably connected to the two clamping arms of the second holding unit.

[0019] By adopting the above technical solutions, the design of the holding component significantly improves the anti-falling ability of the pipe pile mold and further resists the vertical falling trend of the pipe pile mold caused by vibration or acceleration.

[0020] A further feature of this invention is that the driven component includes a first driven shaft and a second driven shaft, which are arranged opposite to each other. The first driven shaft passes through the lower end of the left side plate, the upper ends of the two clamping arms of the first holding unit, and the lower end of the right side plate in sequence, and is rotatably connected to these components. The second driven shaft passes through the lower end of the left side plate, the upper ends of the two clamping arms of the second holding unit, and the lower end of the right side plate in sequence, and is rotatably connected to these components.

[0021] By adopting the above technical solution, when the cylinder drives the drive shaft to move up and down, the driven shaft can constrain the movement trajectory of the clamping arm, ensuring that the clamping arms on both sides open or close synchronously, and avoiding uneven force or displacement of the pipe pile mold caused by asynchronous movement.

[0022] The beneficial effects of this utility model are:

[0023] 1. The clamping mechanism and the pile-holding mechanism provide dual fixation. The clamping mechanism generates clamping force through "surface contact" clamping method, applying pressure to the outer wall of the pipe pile mold. The pile-holding mechanism holds the outer wall of the pipe pile mold. The two are set at intervals to form multi-point fixation.

[0024] 2. The clamping mechanism is the main clamping mechanism, and the pile-holding mechanism is the safety clamping mechanism. The pile-holding mechanism can hold the pipe pile mold, increase the contact area, and distribute the pressure. Compared with the existing pipe pile transportation device, it can effectively prevent the pipe pile mold from falling due to loose clamping during the transfer process, eliminating the safety threat to workers and site equipment.

[0025] 3. The clamping mechanism and the pile-holding mechanism can automatically adjust the clamping or encircling radius according to the outer diameter of the pipe pile mold, which is suitable for pipe pile molds of different specifications and improves the versatility of the device.

[0026] 4. The suspension mechanism on the upper part of the main beam can connect the device to the rail transport system, freeing it from the ground movement limitations of traditional flatbed trucks. It can move quickly along the track in scenarios such as factories and construction sites, reducing the impact of ground obstacles on transportation and significantly improving the flexibility and space utilization of transfer.

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] like Figure 1 As shown, this utility model provides a track flatbed transport device for building pipe piles, including a main beam 1, a suspension mechanism 2 fixedly installed on the upper part of the main beam 1, and a plurality of clamping mechanisms 3 and pile-holding mechanisms 4 fixedly installed on the lower part of the main beam 1, with the clamping mechanisms 3 and pile-holding mechanisms 4 arranged at intervals.

[0037] Specifically, the suspension mechanism 2 on the upper part of the main beam 1 can connect the device to the rail transport system, get rid of the ground movement restrictions of traditional flatbed trucks, and move quickly along the track in scenarios such as factories and construction sites, reducing the impact of ground obstacles on transportation and significantly improving the flexibility and space utilization of transfer.

[0038] During the transportation process, the pipe piles are placed in the pipe pile mold. During transportation, the clamping mechanism 3 and the pile holding mechanism 4 clamp and hold the pipe pile mold.

[0039] The clamping mechanism 3 and the pile-holding mechanism 4 provide dual fixation. During transportation, the rigid clamping force of the clamping mechanism 3 applies pressure to the outer wall of the pipe pile mold, while the pile-holding mechanism 4 holds the outer wall of the pipe pile mold, providing a safety function. The two mechanisms are spaced apart to form multi-point fixation. Compared to the traditional method of stacking and transporting on ordinary flatbed trucks, the transportation device of this application can effectively fix the pipe pile mold, avoiding sliding and collisions caused by bumps and turns during transportation, and reducing the risk of damage such as pile cracks and surface wear.

[0040] The pile-holding mechanism 4 can work with the clamping mechanism 3 to hold the pipe pile mold, increasing the contact area and dispersing pressure. Compared with traditional pipe pile transportation devices that only have a clamping mechanism, the pile-holding mechanism provided in this application can effectively prevent the pipe pile mold from falling due to loose clamping during transportation, eliminating the safety threat to workers and site equipment.

[0041] like Figures 2-4 As shown, the clamping mechanism 3 includes a mounting plate 31, a first drive assembly 32, and a clamping unit 33. The first drive assembly 32 includes a drive motor 321 fixedly mounted on the mounting plate 31. The output shaft of the drive motor 321 passes through the mounting plate 31, and a drive wheel 322 is fixedly connected to the end of the output shaft. The clamping unit 33 includes a drive assembly 331, a driving assembly 332, and a gripper 333.

[0042] The gripper 333 uses a "surface contact" clamping method. The gripper 333 clamps the outer surface of the pipe pile mold. Compared with the "point rigid clamping" of the traditional clamping mechanism 3, this surface contact method can significantly disperse pressure and avoid deformation caused by excessive local stress on the pipe pile mold.

[0043] Furthermore, the active component 331 includes a first gear 3311 that meshes with the active wheel 322. A connecting rod 3312 is fixedly connected to the side of the first gear 3311 away from the active wheel 322. The first gear 3311 is rotatably connected to the mounting plate 31 through a first pin 3313. The end of the connecting rod 3312 is rotatably connected to the gripper 333 through a second pin 3314.

[0044] Furthermore, the drive assembly 332 includes a drive rod 3321 disposed below the connecting rod 3312. One end of the drive rod 3321 is rotatably connected to the mounting plate 31 via a third pin 3322, and the other end is rotatably connected to the gripper 333 via a fourth pin 3323. The clamping unit 33 is provided in two sets, which are symmetrically arranged about the pitch circle center line of the first gear 3311, and the transmission is achieved through the meshing of the two first gears 3311 of the two clamping units 33.

[0045] Specifically, the two sets of clamping units 33 are symmetrically arranged about the pitch circle center line of the first gear 3311. When the drive motor 321 drives the drive wheel 322 to rotate, the drive wheel 322 simultaneously drives the first gear 3311 meshing with it to rotate synchronously. The first gear 3311 drives the first gear 3311 on the other side symmetrical to it to rotate. This symmetrical structure allows the two clamping claws 333 to move closer to or further away from the center synchronously, ensuring that the clamping force on the outer wall of the pipe pile mold is evenly distributed, and avoiding deformation or displacement of the pipe pile due to uneven force on one side.

[0046] Furthermore, the connecting rod 3312 in the active component 331 and the driving rod 3321 in the driving component 332 form a linkage structure through a pin. When the drive motor 321 outputs torque, the rotation of the first gear 3311 is transmitted to the gripper 333 through the connecting rod 3312. At the same time, the driving rod 3321 provides reverse support through the third pin 3322, forming a force-amplifying effect similar to a "lever". This structural design can amplify the driving force of the motor, enabling the gripper 333 to apply a greater rigid clamping force to the pipe pile mold, effectively fixing the pipe pile mold.

[0047] The four-bar linkage formed by the connecting rod 3312 and the driving rod 3321 through the pins converts the rotational motion of the first gear 3311 into the linear opening and closing motion of the gripper 333. This motion conversion method has a short and direct path, reduces energy loss in traditional transmission methods, and improves power transmission efficiency. At the same time, the pin connections adopt a low-friction design, which further reduces energy loss and improves the energy efficiency ratio of the drive motor 321.

[0048] Furthermore, the active component 331 and the driving component 332 are symmetrically provided with auxiliary components 34 via the mounting plate 31. The auxiliary components 34 include a first auxiliary rod 341 and a second auxiliary rod 342. One end of the first auxiliary rod 341 is rotatably connected to the mounting plate 31 via a first pin 3313, and the other end is rotatably connected to the gripper 333 via a second pin 3314. One end of the second auxiliary rod 342 is rotatably connected to the mounting plate 31 via a third pin 3322, and the other end is rotatably connected to the gripper 333 via a fourth pin 3323. The auxiliary components 34 are provided in two sets and are symmetrically arranged with the pitch circle center line of the first gear 3311 as the axis.

[0049] Specifically, the two sets of auxiliary components 34 are symmetrically arranged with the center line of the first gear 3311 pitch circle as the axis, which corresponds to the symmetry of the active component 331 and the driving component 332, further ensuring the synchronous movement of the grippers 333 on both sides. Even in high-speed transportation or bumpy environments, the auxiliary components 34 can suppress the asymmetrical movement of the grippers 333 and improve the clamping stability.

[0050] The auxiliary component 34 forms redundant support with the active and driving component 332. Even if a link 3312 or pin experiences slight wear, the auxiliary component 34 can still maintain the normal operation of the gripper 333, reducing the risk of loosening due to single-point failure and improving system reliability.

[0051] like Figures 5-6 As shown, the pile holding mechanism 4 includes a mounting frame 41, a second drive assembly 42, a driven assembly 44 located below the second drive assembly 42, and holding assemblies 43 located on the front and rear sides of the second drive assembly 42.

[0052] The holding component 43 is used to fix the pipe pile mold in a ring shape, forming multi-point support. The holding component 43 can automatically adjust the ring radius according to the outer diameter of the pipe pile mold, which is applicable to pipe pile molds of different specifications and improves the versatility of the device.

[0053] The pile gripping mechanism 4 and the clamping mechanism 3 complement each other, jointly resisting the bumps, vibrations and acceleration changes during transportation, greatly reducing the risk of the pipe pile mold shaking or displacement. Moreover, as an independent fixing unit, the pile gripping mechanism 4 can still maintain the basic fixation of the pipe pile mold even if the clamping mechanism 3 fails, providing safety redundancy.

[0054] Furthermore, the mounting frame 41 includes a positioning plate 411, with a left side plate 412 and a right side plate 413 fixedly mounted on the left and right sides of the positioning plate 411, respectively. The second drive assembly 42 includes a cylinder 421 fixed on the positioning plate 411. A support plate 422 is fixedly connected to the end of the telescopic shaft of the cylinder 421. Support rods 423 are rotatably connected to the ends of the left and right sides of the support plate 422. Taking the overall front and rear orientation of the device as a reference, the lower ends of the two support rods 423 on the front side are provided with a first drive shaft 424 rotatably connected to them, and the lower ends of the two support rods 423 on the rear side are provided with a second drive shaft 425 rotatably connected to them. The first drive shaft 424 and the second drive shaft 425 are arranged opposite to each other.

[0055] Furthermore, the holding assembly 43 includes a first holding unit 431 and a second holding unit 432. Both the first holding unit 431 and the second holding unit 432 include a clamping arm 433 and a holding rod 434. The holding rod 434 is fixedly disposed at the lower end of the clamping arm 433. The vertical angle between the holding rod 434 and the clamping arm 433 is 90°. The first holding unit 431 and the second holding unit 432 are disposed opposite to each other. The distance between the two clamping arms 433 of the first holding unit 431 is greater than the distance between the two clamping arms 433 of the second holding unit 432, and the distance between the two clamping arms 433 of the first holding unit 431 is greater than the sum of the widths of the two clamping arms 433 of the second holding unit 432.

[0056] Specifically, cylinder 421 drives support plate 422 to move up and down, and through support rods 423 on the left and right sides, it drives the first active shaft 424 on the front side and the second active shaft 425 on the rear side to move in opposite directions or in opposite directions, so as to realize the synchronous action of the front and rear holding units, ensuring that the pipe pile mold is always in the center position during transportation and avoiding uneven force caused by displacement.

[0057] When the cylinder 421 extends or retracts, the angles of the two support rods 423 change synchronously, so that the first drive shaft 424 and the second drive shaft 425 move in parallel, automatically adapting to pipe pile molds of different diameters, and achieving precise centering without the need for an additional positioning mechanism.

[0058] Furthermore, the distance between the two clamping arms 433 of the first holding unit 431 is greater than the sum of the widths of the two clamping arms 433 of the second holding unit 432. The positions of the first holding unit 431 and the second holding unit 432 will not conflict. When the holding rod 434 contacts the surface of the pipe pile mold, the inner and outer clamping arms 433 can work together to form a multi-level encircling effect, which significantly improves the anti-falling ability. The angle between the holding rod 434 and the clamping arm 433 is 90°, so that the holding rod 434 can form an upward component force when it contacts the pipe pile mold, further resisting the vertical falling tendency of the pipe pile mold caused by vibration or acceleration.

[0059] The structural design of the holding rod 434 allows it to form a large contact area with the bottom surface of the pipe pile mold, dispersing pressure and avoiding local stress concentration caused by traditional point contact or line contact.

[0060] Furthermore, the two ends of the first active shaft 424 are rotatably connected to the two clamping arms 433 of the first holding unit 431, and the two ends of the second active shaft 425 are rotatably connected to the two clamping arms 433 of the second holding unit 432.

[0061] Furthermore, the driven assembly 44 includes a first driven shaft 441 and a second driven shaft 442, which are arranged opposite to each other. The first driven shaft 441 passes through the lower end of the left side plate 412, the upper ends of the two clamping arms 433 of the first holding unit 431, and the lower end of the right side plate 413 in sequence, and is rotatably connected to these components. The second driven shaft 442 passes through the lower end of the left side plate 412, the upper ends of the two clamping arms 433 of the second holding unit 432, and the lower end of the right side plate 413 in sequence, and is rotatably connected to these components.

[0062] Specifically, when the cylinder 421 drives the drive shaft to move up and down, the driven shaft can constrain the movement trajectory of the clamping arm 433, ensuring that the clamping arms 433 on both sides open or close synchronously, avoiding uneven force or displacement of the pipe pile mold due to asynchronous movement.

[0063] The specific working process of this application:

[0064] S1: Equipment preparation and material loading stage

[0065] Using the upper suspension mechanism 2 of the main beam 1, the entire transportation device is connected and fixed to the rail transportation system, allowing the device to move freely along the track without being disturbed by ground obstacles; driven by the track, the device is moved to the pipe pile storage area, so that the clamping mechanism 3 and the pile holding mechanism 4 are aligned with the pipe pile mold to be transported, and the initial positioning is completed.

[0066] S2: Clamping Mechanism 3 Workflow

[0067] When the drive motor 321 of the clamping mechanism 3 is powered on, the output shaft rotates and drives the drive wheel 322 to rotate. The drive wheel 322 meshes with the first gear 3311. Since the two sets of clamping units 33 are symmetrical about the pitch circle center line of the first gear 3311 and the two first gears 3311 mesh with each other, when the drive wheel 322 rotates, the first gears 3311 on both sides rotate synchronously in opposite directions, one side rotates clockwise and the other side rotates counterclockwise.

[0068] The rotation of the first gear 3311, through a four-bar linkage consisting of connecting rod 3312, driving rod 3321, and pin, converts the gear's rotational motion into the linear opening and closing motion of the gripper 333. Simultaneously, the first auxiliary rod 341 and the second auxiliary rod 342 of the auxiliary component 34 move in sync, enhancing motion stability and providing redundant support. Driven by the four-bar linkage, the grippers 333 on both sides move synchronously towards the center of the pipe pile mold until the "surface contact" grippers 333 adhere to the outer wall of the pipe pile mold. During this process, the "leveraging" effect of the four-bar linkage amplifies the motor's driving force, causing the grippers 333 to apply a rigid clamping force. The auxiliary component 34 suppresses asymmetrical movement of the grippers 333, ensuring uniform force on the pipe pile mold and completing the initial fixing of the pipe pile mold.

[0069] S3: Pile-holding mechanism 4-step workflow

[0070] When the cylinder 421 of the pile clamping mechanism 4 is vented, the telescopic shaft is pulled back, pushing the support plate 422 to move upward. The upward movement of the support plate 422 causes the support rods 423 on both sides of the support plate 422 to rotate around the end, which in turn causes the first active shaft 424 on the front side and the second active shaft 425 on the rear side to move towards each other, clamping the pipe pile mold.

[0071] When the drive shaft moves, the driven shaft passes through the left side plate 412, clamping arm 433, and right side plate 413 in sequence, forming a rotational constraint. The clamping arms 433 of the first holding unit 431 and the second holding unit 432 are limited by the driven shaft and move synchronously towards each other with the drive shaft. The first holding unit 431 and the second holding unit 432 form a "nested" embrace. Because the holding rod 434 forms a 90° angle with the clamping arm 433, when it contacts the pipe pile mold, it not only forms a large area of ​​contact to disperse pressure, but also generates an upward component force to resist the tendency of the pipe pile mold to fall off.

[0072] S4: Pipe Pile Transportation Stage

[0073] The device uses a track system to transport the fixed pipe pile mold to the target location.

[0074] During transportation, the clamping mechanism 3 relies on surface clamping force and the stability of the four-bar linkage to resist the horizontal sliding tendency of the pipe pile mold caused by track bumps and turns; the auxiliary component 34 continuously suppresses the asymmetrical movement of the gripper 333 to ensure clamping reliability.

[0075] The pile-holding mechanism 4 encircles the sides and bottom of the pipe pile mold, dispersing vibration energy and reducing the risk of the pipe pile mold falling off in the vertical direction; even if the clamping mechanism 3 suddenly fails, the pile-holding mechanism 4 can still independently maintain the basic fixation of the pipe pile mold, providing safety redundancy.

[0076] S5: Unloading Stage

[0077] The pile clamping mechanism 4 is released: the cylinder 421 is vented and reversed, the telescopic shaft extends, the support plate 422 moves down, driving the support rod 423 and the drive shaft to move in opposite directions, the clamping arm 433 of the clamping unit opens, and the clamping and fixing of the pipe pile mold is released.

[0078] Clamping mechanism 3 releases: Drive motor 321 reverses, drive wheel 322 drives first gear 3311 to rotate in the opposite direction, and through four-bar linkage with auxiliary component 34, the gripper 333 opens to both sides, releasing the clamping force of the pipe pile.
