Description

Technical Field

[0001] This utility model relates to the field of handling device technology, specifically a hydraulic pile foundation handling device. Background Technology

[0002] Water conservancy projects require pile foundations to create a solid foundation, which is essential for the stability of the project. Currently, precast piles are commonly used for these foundations, and they are typically manufactured in a factory and then transported to the construction site.

[0003] According to a public notice of a hydraulic pile foundation handling device (Announcement No.: CN222876040U), in the above application, two clamping plates maintain a clamping state on the pile foundation to prevent the pile foundation from slipping or moving, ensuring the safe handling of the pile foundation. After the pile foundation is handled to the designated position, the operator rotates the rotating rod in the opposite direction, so that the clamping plates gradually move away from the pile foundation in the sliding groove. After the clamping plates are completely released from the pile foundation, the operator can remove the auxiliary plate and then take out the pile foundation. This achieves the effect of stably clamping the pile foundation, high handling efficiency, and protection of the pile foundation.

[0004] However, in actual use, the aforementioned equipment requires the pile foundations to be transported at a certain height above the ground using a handling device. Therefore, the pile foundations need vertical displacement during loading and unloading, necessitating the use of tools. Otherwise, damage to the pile foundations could occur, affecting their subsequent service life. However, transporting the pile foundations with tools would increase the transportation burden and reduce transport safety and efficiency. Therefore, we propose a hydraulic pile foundation handling device. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic pile foundation transportation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic pile foundation handling device, comprising a vehicle body, rollers at the bottom of the vehicle body, a push handle fixedly installed at the end of the vehicle body, a storage cavity inside the vehicle body, a detachable insert plate installed on the inner wall of the storage cavity away from the push handle, a loading and unloading assembly inside the storage cavity, the loading and unloading assembly including a limiting groove, the limiting groove being opened on the inner walls of the left and right sides of the storage cavity, a sliding rod movably installed inside the limiting groove, a support plate being fixedly installed through and on the outer wall of the sliding rod, a movable cavity being opened on the upper surface of the support plate, a roller being rotatably installed on the inner wall of the movable cavity, a clamping plate being slidably installed on the arc-shaped inner wall of the roller, and a spring being fixedly connected between the clamping plate and the inner wall of the roller.

[0007] Preferably, the idler roller is coaxially fixedly mounted with a limiting toothed ring, an adjusting seat is slidably mounted on the inner wall of the movable cavity, an adjusting cavity is opened on the inner wall of the adjusting seat, an elastic column is fixedly mounted on the arc-shaped inner surface of the adjusting cavity, a trapezoidal block is fixedly mounted on the end of the elastic column, a threaded slider is slidably mounted on the inner wall of the support plate, an adjusting screw is rotatably mounted on the inner wall of the support plate, and a deceleration assembly is provided inside the adjusting seat.

[0008] Preferably, the number of adjusting seats, movable cavities and rollers is provided in multiple sets. The multiple sets of adjusting seats, movable cavities and rollers are evenly distributed in a linear array on the upper surface of the support plate, and the multiple sets of adjusting seats are fixedly connected to each other by a horizontal plate. At the same time, the outer wall of the center of the multiple sets of adjusting seats is fixedly connected to the outer wall of the threaded slider.

[0009] Preferably, the outer surface of the card plate away from the idler roller is inclined, and the inclined outer wall of the card plate at the top of the idler roller is set towards the side of the vehicle body away from the push handle. The number of card plates is set to multiple sets, and the multiple sets of card plates are evenly distributed in a circumferential array on the arc-shaped outer surface of the idler roller.

[0010] Preferably, the size of the trapezoidal block is adapted to the gap between the teeth on the arc-shaped outer surface of the limiting tooth ring, and the trapezoidal block is set in the shape of a right-angled trapezoid. The elastic column and the trapezoidal block are located at the center of the adjustment cavity near the limiting tooth ring.

[0011] Preferably, the deceleration assembly includes a friction ring, which is fixedly installed on the side wall of the limiting tooth ring. A fastening plate is fixedly installed on the arc-shaped inner wall of the adjustment cavity. A protrusion is fixedly installed on the outer surface of the fastening plate near the limiting tooth ring. A circular hole is provided at the center of the fastening plate.

[0012] Preferably, the inner diameter of the circular hole is larger than the outer diameter of the roller end, and the inner diameter of the circular hole is adapted to the outer diameter of the friction ring. The thickness of the friction ring gradually decreases from the side of the limiting tooth ring outward. The number of protrusions is arranged in multiple sets, and the multiple sets of protrusions are evenly distributed in a circumferential array on the outer wall of the sticking plate near the limiting tooth ring. The width of the protrusion is smaller than the tooth spacing on the arc-shaped outer wall of the limiting tooth ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the mutual cooperation of the support plate, roller, clamping plate, spring, limiting toothed ring, adjusting seat, adjusting cavity, elastic column, trapezoidal block, threaded slider, adjusting screw, friction ring, sticking plate, protrusion, and circular hole, the roller supports the hydraulic pile foundation during loading and reduces its loading resistance. At the same time, the reverse rotation of the elastic column and trapezoidal block and the sliding contact of the clamping plate prevent the hydraulic pile foundation from slipping and being damaged during loading. By adjusting the position of the threaded slider, the relative positions of the elastic column, trapezoidal block, and limiting toothed ring are changed, so that the hydraulic pile foundation will not interfere with the reverse rotation of the roller during unloading. At the same time, the friction deceleration of the protrusion, circular hole, and friction ring prevents the roller from rotating rapidly. Therefore, the hydraulic pile foundation can be unloaded at a relatively slow speed, ensuring its unloading safety and completing the transportation of the hydraulic pile foundation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-8 The diagram shows a hydraulic pile foundation transport device, including a vehicle body 1. Rollers 2 are installed at the bottom of the vehicle body 1, and a push handle 3 is fixedly installed at the end of the vehicle body 1. A storage cavity 4 is formed inside the vehicle body 1. A plate 5 is detachably installed on the inner wall of the end of the storage cavity 4 away from the push handle 3. A loading and unloading assembly is provided inside the storage cavity 4, including a limiting groove 6. The limiting groove 6 is formed on the inner walls of the left and right sides of the storage cavity 4. A sliding rod 7 is movably installed inside the limiting groove 6. A support plate 8 is fixedly installed through the outer wall of the sliding rod 7. A movable cavity 9 is formed on the upper surface of the support plate 8. A support is rotatably installed on the inner wall of the movable cavity 9. Roller 10, a retaining plate 11 is slidably installed on the arc-shaped inner wall of the roller 10, a spring 12 is fixedly connected between the retaining plate 11 and the inner wall of the roller 10, a limiting toothed ring 13 is coaxially fixedly installed on the roller 10, an adjusting seat 14 is slidably installed on the inner wall of the movable cavity 9, an adjusting cavity 15 is opened on the inner wall of the adjusting seat 14, an elastic column 16 is fixedly installed on the arc-shaped inner surface of the adjusting cavity 15, a trapezoidal block 17 is fixedly installed at the end of the elastic column 16, a threaded slider 18 is slidably installed on the inner wall of the support plate 8, an adjusting screw 19 is rotatably installed on the inner wall of the support plate 8, and a deceleration assembly is provided inside the adjusting seat 14.

[0025] Please see Figure 2 , Figure 3 The width of the support plate 8 is adapted to the width of the storage cavity 4, and the length of the support plate 8 is equal to the distance between the inner wall of the storage cavity 4 and the insert plate 5. The inner wall of the vehicle body 1 is provided with a slot adapted to the insert plate 5, so that the support plate 8 can slide along the inner surface of the storage cavity 4 to facilitate the loading and unloading of the hydraulic pile foundation placed on the support plate 8. Specifically, the slot allows the insert plate 5 to be detachably connected to the vehicle body 1, and the position of the insert plate 5 is just right to block the support plate 8 in the horizontal direction to prevent it from slipping out of the vehicle body 1, while ensuring that the transported hydraulic pile foundation will not fall outward, thus ensuring the safety of transportation.

[0026] Please see Figure 4 , Figure 5Multiple sets of adjusting seats 14, movable cavities 9, and rollers 10 are arranged in a linear array and evenly distributed on the upper surface of the support plate 8 to support the hydraulic pile foundation. At the same time, due to the arrangement of multiple sets of rollers 10, when the hydraulic pile foundation moves left and right along the top of the support plate 8, rolling friction can replace sliding friction, reducing the frictional resistance of the hydraulic pile foundation during loading and unloading, and reducing the labor pressure of the workers. The multiple sets of adjusting seats 14 are fixedly connected in pairs by horizontal plates, and the outer wall of the center of the multiple sets of adjusting seats 14 is fixedly connected to the outer wall of the threaded slider 18, so that the threaded slider 18 can drive the multiple sets of adjusting seats 14 to slide along the surface of the support plate 8.

[0027] Please see Figure 6 The outer surface of the end of the pallet 11 away from the roller 10 is set in an inclined shape. The inclined outer wall of the pallet 11 at the top of the roller 10 is set towards the side of the vehicle body 1 away from the push handle 3. There are multiple sets of pallets 11, which are evenly distributed in a circumferential array on the arc-shaped outer surface of the roller 10. At the same time, the inclined surface of the pallet 11 contacts the bottom surface of the hydraulic pile foundation when the hydraulic pile foundation is being fed, which inhibits its downward movement trend. However, it does not interfere with the hydraulic pile foundation as it moves upward along the support plate 8, thus facilitating the safe and stable feeding of the hydraulic pile foundation.

[0028] Please see Figure 7 , Figure 8 The size of the trapezoidal block 17 is adapted to the gap between the teeth on the arc-shaped outer surface of the limiting tooth ring 13, and the trapezoidal block 17 is set as a right-angled trapezoid. The elastic column 16 and the trapezoidal block 17 are set on the side of the center of the adjustment cavity 15 near the limiting tooth ring 13. There are multiple sets of elastic columns 16 and trapezoidal blocks 17. The multiple sets of elastic columns 16 and trapezoidal blocks 17 are evenly distributed in a circumferential array on the arc-shaped inner surface of the adjustment cavity 15. When the support plate 8 is feeding the hydraulic pile foundation, the hydraulic pile foundation moves upward, causing the roller 10 to rotate counterclockwise. At this time, the limiting tooth ring 13 rotates with the roller 10. The teeth of the limiting tooth ring 13 squeeze the inclined surface of the trapezoidal block 17, thereby causing the elastic column 16 to contract. The right-angled side of the trapezoidal block 17 suppresses the reverse rotation tendency of the limiting tooth ring 13, so that the hydraulic pile foundation will not slide downward during the feeding process, ensuring the safety and stability of the hydraulic pile foundation during the feeding process.

[0029] During the material feeding process, the user rotates the adjusting screw 19 to control the threaded slider 18 to drive multiple sets of adjusting seats 14 to slide along the inner wall of the support plate 8, so that the elastic column 16 and trapezoidal block 17 disengage from the limiting toothed ring 13, thereby preventing the trapezoidal block 17 from restricting the reverse rotation of the roller 10, thus facilitating the material feeding work of the hydraulic pile foundation.

[0030] Please see Figure 7 , Figure 8 The deceleration assembly includes a friction ring 20, which is fixedly installed on the side wall of the limiting toothed ring 13. A fastening plate 21 is fixedly installed on the arc-shaped inner wall of the adjusting cavity 15. A protrusion 22 is fixedly installed on the outer surface of the fastening plate 21 near the limiting toothed ring 13. A circular hole 23 is opened at the center of the fastening plate 21. Two sets of deceleration assemblies are provided, and the two sets of deceleration assemblies are mirror images of each other at both ends of the idler roller 10, so that the idler roller 10 is more balanced and stable when subjected to force.

[0031] Please see Figure 7 , Figure 8 The inner diameter of the circular hole 23 is larger than the outer diameter of the end of the idler roller 10, and the inner diameter of the circular hole 23 is matched with the outer diameter of the friction ring 20, so that the circular hole 23 will not interfere with the rotation of the idler roller 10 during normal use. The thickness of the friction ring 20 gradually decreases from the side of the limiting toothed ring 13 outwards, and the maximum outer diameter of the friction ring 20 is matched with the inner diameter of the circular hole 23, so that when the friction ring 20 and the circular hole 23 are fully aligned, the circular hole 23 will have a clamping effect on the friction ring 20. There are multiple sets of protrusions 22, which are evenly distributed in a circumferential array on the outer wall of the sticking plate 21 near the limiting toothed ring 13. The width of the protrusions 22 is smaller than the arc-shaped outer diameter of the limiting toothed ring 13. The tooth spacing on the wall is such that, driven by the threaded slider 18, the clamping plate 21 in the multiple sets of adjusting seats 14 drives the protrusion 22 to engage in the gap between the teeth of the limiting tooth ring 13. This causes the roller 10 to rotate clockwise during the unloading process of the hydraulic pile foundation. At this time, since the elastic column 16 and trapezoidal block 17 disengage from the limiting tooth ring 13, they will not completely block the roller 10 from driving the limiting tooth ring 13 to rotate clockwise. At the same time, since the protrusion 22 blocks the rotation of the teeth of the limiting tooth ring 13, the roller 10 will not rotate too fast, thus avoiding damage to the hydraulic pile foundation caused by excessive speed during unloading and ensuring the safety of the hydraulic pile foundation during loading and unloading.

[0032] Working principle: Push the vehicle body 1 to the bottom of the target and position the vehicle body 1. Then pull out the insert plate 5 upward and pull out the support plate 8 outward until the slide bar 7 moves to the rightmost end of the limiting groove 6. Place the right end of the support plate 8 on the ground. At this time, the support plate 8 is tilted. Then push the hydraulic pile foundation to the left along the upper surface of the support plate 8. Due to the setting of the roller 10, the frictional resistance of the hydraulic pile foundation during the feeding process is reduced until the hydraulic pile foundation is completely inserted into the support plate 8. At this time, lift the right end of the support plate 8 upward and push it into the receiving cavity 4. After the support plate 8 is completely inserted into the receiving cavity 4, insert the insert plate 5 to complete the feeding of the hydraulic pile foundation.

[0033] Afterwards, the staff pushed the handle 3 to transport the hydraulic pile foundation to the target location using the vehicle body 1, and aligned one side of the insert plate 5 of the vehicle body 1 with the unloading position.

[0034] Pull out the insert plate 5 again, then pull out the support plate 8 and place the bottom end of the support plate 8 on the platform where the material needs to be unloaded. Then rotate the adjusting screw 19 so that the threaded slider 18 drives the adjusting seat 14 to disengage the elastic column 16 and trapezoidal block 17 from the limiting tooth ring 13 until the clamping plate 21 is attached to the side of the limiting tooth ring 13. At this time, push the hydraulic pile foundation to the right and unload it under the rolling of the roller 10. Due to the frictional deceleration of the protrusion 22, the circular hole 23 and the friction ring 20, the roller 10 will not rotate quickly. Therefore, the hydraulic pile foundation can be unloaded at a relatively slow speed to ensure its unloading safety and complete the transportation of the hydraulic pile foundation.

[0035] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
