Description

Technical Field

[0001] This application relates to the technical field of water conservancy construction, and particularly relates to a handling device for pile foundation construction in water conservancy projects. Background Technique

[0002] The pile foundation is a commonly used deep foundation form, which is composed of foundation piles and a bearing platform connected to the top of the piles. If the entire pile body is buried in the soil and the bottom surface of the bearing platform contacts the soil mass, it is called a low-capacity pile foundation. If the upper part of the pile body is exposed above the ground and the bottom of the bearing platform is above the ground, it is called a high-capacity pile foundation. Building pile foundations are usually low-capacity pile foundations, while high-capacity pile foundations are commonly used in water conservancy projects such as bridges and docks.

[0003] Currently, the construction of pile foundations is usually divided into two categories: precast piles and cast-in-place piles. The pile foundations used in water conservancy projects are usually mainly precast piles. During construction, several pile foundations need to be transported to different construction positions respectively. When transporting the pile foundations, the staff first fix them with steel ropes and then use a crane to lift and transport them, resulting in low construction efficiency. Summary of the Invention

[0019] 2. When it is necessary to export the pile foundations from the blanking port, drive the baffle frame to slide away from the driving roller through the second driving part. The limiting frame continues to close the blanking port under the elastic force of the first elastic part. After that, drive the driving roller to rotate through the first driving source. The driving roller abuts against the surface of the pile foundation and squeezes the pile foundation, extruding the pile foundation from between the driving roller and the driven roller. When the pile foundation is being extruded, the limiting frame slides towards the baffle frame. When the pile foundation is extruded from between the driving roller and the driven roller, the limiting frame continues to close the blanking port under the elastic force of the first elastic part, preventing a large amount of pile foundations from sliding down from the blanking port position, thereby facilitating the control of the amount of pile foundations sliding down from the blanking port.

[0033] Refer to Figure 1 , 3 , two guide rods 43 are fixedly arranged on the transfer frame 4. The length directions of the two guide rods 43 are both vertical. Two guiding holes are vertically formed on the sliding frame 3. The guide rods 43 correspond to the guiding holes one by one, and the guide rods 43 are slidably inserted into their respective corresponding guiding holes. The guide rods 43 prevent the transfer frame 4 from shaking during the transportation of the pile foundation.

[0034] Refer to Figure 4 , a feeding port 21 is formed on the top wall of the material box 2, a blanking port 22 is formed on the bottom wall of the material box 2, an inclined guide plate 23 is fixedly arranged in the material box 2, and the inclined guide plate 23 is inclined downward along the direction close to the blanking port 22. A limiting mechanism for preventing the pile foundation from sliding down from the blanking port 22 is arranged on the material box 2. The limiting mechanism includes a material blocking frame 24 and a second driving member 25. A receiving groove 26 is formed on the side wall of the blanking port 22. The material blocking frame 24 is slidably arranged in the receiving groove 26. The second driving member 25 includes a hydraulic cylinder. The hydraulic cylinder is fixedly arranged in the receiving groove 26, and the piston rod of the hydraulic cylinder extends into the receiving groove 26 and is fixedly connected to the material blocking frame 24.

[0035] Refer to Figure 4 , a driving roller 27 is rotatably arranged in the blanking port 22. The axial direction of the driving roller 27 is perpendicular to the sliding direction of the material blocking frame 24. A first driving source 28 for driving the driving roller 27 to rotate is arranged on the frame 1. The first driving source 28 includes a first motor. The first motor is fixedly arranged on the frame 1, and the output shaft of the first motor is coaxially and fixedly connected to the driving roller 27.

[0036] Refer to Figure 4 Figure 4 , one end of the material baffle 24 close to the driving roller 27 is provided with an installation groove 251. A limiting frame 252 is slidably arranged in the installation groove 251 along the axial direction perpendicular to the driving roller 27. A first elastic member 253 for driving the limiting frame 252 to slide towards the driving roller 27 is arranged on the material baffle 24. The first elastic member 253 includes a compression spring. The compression spring is arranged in the installation groove 251. One end of the compression spring is fixedly connected to the bottom wall of the installation groove 251, and the other end of the compression spring is fixedly connected to the limiting frame 252. A driven roller 29 is rotatably arranged on the limiting frame 252. The axial directions of the driving roller 27 and the driven roller 29 are parallel.

[0037] All the pile foundations to be transported are stored in the material box 2. When it is necessary to export the pile foundations from the blanking port 22, the material baffle 24 is driven to slide away from the driving roller 27 by the hydraulic cylinder. The limiting frame 252 continues to close the blanking port 22 under the elastic force of the compression spring, and the driving roller 27 abuts against the driven roller 29. Then, the driving roller 27 is driven to rotate by the first motor. The driving roller 27 abuts against the surface of the pile foundation and extrudes the pile foundation, and the pile foundation is extruded from between the driving roller 27 and the driven roller 29. When the pile foundation is being extruded, the limiting frame 252 slides towards the material baffle 24. After the pile foundation is extruded from between the driving roller 27 and the driven roller 29, the limiting frame 252 continues to close the blanking port 22 under the elastic force of the compression spring, preventing a large amount of pile foundations from sliding down from the position of the blanking port 22, so as to facilitate controlling the amount of pile foundations sliding down from the blanking port 22. According to the number of pile foundations required to be placed at the construction position, when the number of pile foundations sliding down from the blanking port 22 reaches the specified number, the material baffle 24 is driven to slide towards the driving roller 27 by the hydraulic cylinder, thereby preventing the limiting frame 252 from sliding and closing the blanking port 22.

[0038] Refer to Figure 4 、 5 5 , a plurality of guide plates 51 are arranged on one side of the guide frame 5 close to the material box 2. Adjacent two guide plates 51 are connected by hinges. The guide plates 51 located on both sides are respectively hinged to the guide frame 5. Anti-slip pads 511 are fixedly arranged at the ends of the guide plates 51 far from the guide frame 5. The anti-slip pads 511 are made of rubber material, and anti-slip stripes are arranged at the ends of the anti-slip pads 511 far from the guide plates 51.

[0039] Refer to Figure 6, a plurality of buffer sleeves 52 are fixedly arranged on the material guiding frame 5. A buffer rod 521 is slidably inserted into the buffer sleeve 52 along the axial direction of the buffer sleeve 52. A second elastic member 522 for driving the buffer rod 521 to slide towards the material guiding plate 51 is arranged in the buffer sleeve 52. The second elastic member 522 includes a return spring. The return spring is arranged in the buffer sleeve 52. One end of the return spring abuts against the material guiding frame 5, and the other end of the return spring abuts against the buffer rod 521. The buffer rods 521 all abut against the respective material guiding plates 51. The pile foundation falling from the blanking port 22 drops onto the material guiding frame 5, and the impact force when the pile foundation drops is offset by the return spring. Through the arrangement of the anti-slip pads 511, the pile foundation rolls on the material guiding plate 51. When the pile foundation rolls on the material guiding plate 51, the material guiding plate 51 at the position of the pile foundation slides towards the material guiding frame 5 under the influence of the gravity of the pile foundation, while the material guiding plate 51 under the pile foundation arches away from the material guiding frame 5 under the support of the buffer rod 521 and the return spring, so as to decelerate the rolling of the pile foundation on the material guiding frame 5, and effectively reduce the impact force of the pile foundation on the placement groove 42 and the transfer rack 4 when the pile foundation enters the placement groove 42.

[0040] Refer to Figure 7 , a first driving member 44 for driving the placement rack 41 to rotate is arranged on the transfer rack 4. The first driving member 44 includes a servo cylinder. One end of the servo cylinder is hinged to the transfer rack 4, and the piston rod of the servo cylinder is hinged to the placement rack 41. After the transfer rack 4 transports the pile foundation to the ground at the construction position, the servo cylinder is used to drive the placement rack 41 to rotate, so as to facilitate pouring out the pile foundation from the placement groove 42.

[0041] Refer to Figure 7 , a buffer plate 45 is slidably arranged in the placement groove 42 along the direction perpendicular to the bottom wall of the placement groove 42. The buffer plate 45 is adapted to the inside of the placement groove 42. A guide block is fixedly arranged on the buffer plate 45. A guide groove is formed in the side wall of the placement groove 42 along the sliding direction of the buffer plate 45. The guide block is slidably arranged in the guide groove. A third elastic member 46 for driving the buffer plate 45 to slide away from the placement rack 41 is arranged on the placement rack 41. The third elastic member 46 includes shock-absorbing springs. A plurality of shock-absorbing springs are arranged. A plurality of storage grooves are formed in the bottom wall of the placement groove 42. The storage grooves correspond to the shock-absorbing springs one by one. The shock-absorbing springs are arranged in the storage grooves. One end of the shock-absorbing spring abuts against the bottom wall of the storage groove, and the other end of the shock-absorbing spring abuts against the buffer plate 45. When the pile foundation enters the placement groove 42 on the placement rack 41, the impact force of the pile foundation on the placement rack 41 is reduced by the shock-absorbing springs and the buffer plate 45.

[0042] The implementation principle of a pile foundation construction handling device in an embodiment of this application is as follows: The pile foundations to be handled are stored in the material box 2. Each steering oil cylinder 12 drives the corresponding bracket 14 to rotate respectively to adjust the moving direction of the frame 1. Then, each servo motor 13 drives the corresponding driving wheel 11 to rotate, so as to drive the frame 1 to move and drive the pile foundation to the construction position. After that, the hydraulic cylinder drives the baffle 24 to slide away from the driving roller 27. The limiting frame 252 continues to close the blanking port 22 under the elastic force of the compression spring, and the driving roller 27 abuts against the driven roller 29. Then, the first motor drives the driving roller 27 to rotate. The driving roller 27 abuts against the surface of the pile foundation and extrudes the pile foundation, and extrudes the pile foundation from between the driving roller 27 and the driven roller 29. According to the number of pile foundations required to be placed at this construction position, the number of pile foundations sliding out from the blanking port 22 is controlled. When the number of pile foundations sliding down from the blanking port 22 reaches the specified number, the hydraulic cylinder drives the baffle 24 to slide towards the driving roller 27, thereby preventing the limiting frame 252 from sliding and closing the blanking port 22.

[0043] The pile foundations sliding down from the blanking port 22 fall onto the material guiding frame 5. The impact force when the pile foundations fall is offset by the return spring. Through the setting of the anti-slip pad 511, the pile foundations roll on the material guiding plate 51. When the pile foundations roll on the material guiding plate 51, the material guiding plate 51 at the position of the pile foundation slides towards the material guiding frame 5 under the influence of the gravity of the pile foundation, while the material guiding plate 51 under the pile foundation arches away from the material guiding frame 5 under the support of the buffer rod 521 and the return spring, so as to decelerate the rolling of the pile foundations on the material guiding frame 5. Then, the pile foundations enter the placement groove 42 of the placement frame 41. Then, the second motor drives the lead screw 15 to rotate, drives the sliding frame 3 to slide, and then the third motor drives the wire winding wheel 32 to rotate, thereby driving the transfer frame 4 to lift and lower, and transporting the pile foundations to the ground at the construction position. The servo cylinder drives the placement frame 41 to rotate, so as to facilitate pouring out the pile foundations from the placement groove 42 and complete the handling of the pile foundations. Then, continue to drive the frame 1 to move to the next construction position and repeat the above steps. When handling the pile foundations, it is efficient and fast, greatly improving the efficiency of handling the pile foundations.

[0044] The above are all the preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
