Description

Technical Field

[0001] The present application relates to the technical field of concrete pipe pile production, and in particular to a pile turning frame for concrete pipe piles. Background Art

[0002] In the production process of concrete pipe piles, in order to ensure the quality of the inner and outer surfaces of the pipe piles, they often need to be turned over during the curing process.

[0003] Existing pipe pile turning devices usually use cranes or special hydraulic turning machines to achieve turning operations. Although these devices can meet production needs to a certain extent, turning operations performed by cranes are not only inefficient but also have high site requirements, making them inconvenient for continuous production and automated assembly lines. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the present application provides a pile-turning frame for concrete pipe piles, which has the advantages of adapting to pipe piles of different lengths and specifications. It solves the problem that existing pipe pile turning devices usually use cranes or special hydraulic turning machines to perform turning operations. Although these devices can meet production needs to a certain extent, the turning operation performed by crane is not only inefficient, but also has high site requirements, which is not convenient for continuous production and the application of automated assembly lines.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a pile-turning frame for concrete pipe piles, comprising a base plate and a turning frame, wherein four support frames are fixedly connected to one side of the upper end of the base plate, and the four support frames are rotatably connected to a first rotating shaft in a group of two, and a plurality of support rods arranged in a linear array are fixedly connected to the inside of the turning frame, and four first rotating seats arranged in a rectangular array are fixedly connected to the upper end of the turning frame, and the four first rotating seats are rotatably connected to a second rotating shaft in a group of two, and the outer walls of the two second rotating shafts are fixedly connected to two guide rollers distributed in a mirror image, and one side of the turning frame is fixedly connected to two second rotating seats distributed in a mirror image.

[0006] Through the above scheme, the device provides a stable support point for the flipping frame through the first rotating shaft that is internally connected to the four support frames in groups of two, so that the flipping frame can maintain balance when flipping the concrete pipe piles, avoiding safety problems caused by unstable center of gravity. The second rotating shaft that is internally connected to the four first rotating seats at the upper end of the flipping frame, and the guide rollers fixedly connected to the outer wall of the second rotating shaft enable the flipping frame to adapt to pipe piles of different diameters more flexibly during the flipping process, thereby improving the flexibility of the device. The multiple support rods arranged in a linear array and fixedly connected inside the flipping frame are used to enhance the structural strength of the flipping frame. The setting of the guide rollers enables pipe piles of different diameters to remain centered at the upper end of the second rotating shaft, avoiding damage to the pipe piles or operational errors due to offset or shaking, and improving the accuracy and safety of flipping.

[0007] Furthermore, support blocks are fixedly connected on both sides of the flip frame, two first electric push rods are fixedly connected inside the two support blocks, the telescopic ends of four first electric push rods in groups of two are fixedly connected to a lifting plate, the upper ends of the two lifting plates are fixedly connected to a mounting seat, the upper ends of the two lifting plates are fixedly connected to two positioning seats in a mirror distribution, the insides of the two mounting seats are fixedly connected to second electric push rods, the telescopic ends of the two second electric push rods are fixedly connected to a clamp, and one side of the two clamps is fixedly connected to two positioning rods in a mirror distribution.

[0008] Through the above scheme, the height of the lifting plate can be adjusted by the first electric push rod fixedly connected inside the support block. This design enables the device to adapt to concrete pipe piles of different diameters, increasing the flexibility and adaptability of use. The mounting seat and positioning seat on the upper end of the lifting plate provide a stable mounting platform for the second electric push rod and the clamp. At the same time, the coordinated use of the positioning seat and the positioning rod can ensure that the clamp can achieve precise positioning when clamping the pipe pile, avoiding damage to the pipe pile or operational errors caused by position offset. The clamp fixedly connected to the telescopic end of the second electric push rod can realize automatic clamping and release of the concrete pipe pile.

[0009] Furthermore, rubber pads are fixedly connected inside the two clamps.

[0010] Through the above solution, the provision of the rubber pad enables the clamp to provide a soft contact surface when clamping the concrete pipe pile, thereby effectively avoiding direct hard squeezing or scratching of the pipe pile surface by the clamp. The rubber pad not only protects the surface of the pipe pile, but also enhances the clamping stability of the pipe pile by the clamp through its elasticity and friction. During the flipping process, the rubber pad can ensure a close fit between the clamp and the pipe pile, preventing the pipe pile from shaking or slipping.

[0011] Furthermore, one side of the bottom end of the turnover frame is fixedly connected to four support columns arranged in a linear array, and the bottom ends of the four support columns are all fixedly connected to rubber blocks.

[0012] Through the above solution, four support columns arranged in a linear array and fixedly connected to one side of the bottom end of the flip frame provide additional support and stability for the entire device. The rubber blocks fixed at the bottom ends of the support columns have good elasticity and shock-absorbing properties. When the device is working, the rubber blocks can absorb and disperse vibrations and noise from the ground, thereby reducing the impact on the surrounding environment and personnel.

[0013] Furthermore, third rotating seats are fixedly connected on both sides of the bottom end of the flip frame, and two fourth rotating seats distributed in a mirror image are fixedly connected to the side of the upper end of the base plate away from the support frame, and hydraulic rods are rotatably connected between the two third rotating seats and the fourth rotating seat.

[0014] Through the above scheme, the flexible flipping control of the flipping frame can be achieved through the hydraulic rod rotatably connected between the third rotating seat and the fourth rotating seat. The telescopic movement of the hydraulic rod can drive the flipping frame to rotate around its bottom, thereby realizing the flipping operation of the concrete pipe pile.

[0015] Furthermore, the bottom end of the base plate is fixedly connected to a rotating base, and the bottom end of the base plate is fixedly connected to four auxiliary wheels arranged in a rectangular array.

[0016] Through the above solution, the design of the rotating base allows the entire device to change direction by rotation, and the four auxiliary wheels arranged in a rectangular array make the device more stable when rotating.

[0017] Furthermore, the two first rotating shafts are both rotatably arranged inside the second rotating seat.

[0018] According to the above solution, the bottom plate is connected to the second rotating seat on one side of the flip frame through the rotating shaft inside the support frame, and flips around the first rotating shaft during flipping.

[0019] Furthermore, the four positioning rods are all slidably arranged inside the positioning seat.

[0020] With the above solution, the positioning rod can provide additional support and stability during the clamping process through the sliding setting, which helps to ensure that the clamp will not loosen or deform due to uneven force when clamping the pipe pile, thereby improving the reliability and safety of the clamping.

[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0022] The present invention relates to a pile-turning frame for concrete pipe piles. The device provides a stable support point for the turning frame through a first rotating shaft that is internally connected to four support frames in groups of two, so that the turning frame can maintain balance when turning over the concrete pipe pile, avoiding safety problems caused by unstable center of gravity. The second rotating shaft that is internally connected to the four first rotating seats at the upper end of the turning frame and the guide rollers fixedly connected to the outer wall of the second rotating shaft enable the turning frame to more flexibly adapt to pipe piles of different diameters during the turning process, thereby improving the flexibility of the device. The multiple support rods arranged in a linear array and fixedly connected inside the turning frame are used to enhance the structural strength of the turning frame. The setting of the guide rollers enables pipe piles of different diameters to remain centered at the upper end of the second rotating shaft, avoiding damage to the pipe piles or operational errors caused by offset or shaking, and improving the accuracy and safety of turning.

[0034] It should be noted that the device can flip the pipe pile, and can also rotate the pipe pile by rotating the base 24 to change its direction.

[0035] The working principle of the above embodiment is:

[0036] Place the pile turning frame in a suitable working position, ensure that the rotating base 24 and the auxiliary wheel 25 at the bottom end of the base plate 1 are in stable contact with the ground, and adjust the overall direction of the pile turning frame by rotating the rotating base 24 as needed to match it with the construction requirements, start the two second electric push rods 15, and make their telescopic ends drive the clamps 17 to move toward the concrete pipe pile, and the rubber pads 18 inside the clamps 17 contact the surface of the pipe pile, and the pipe pile is clamped by continuing to push the second electric push rods 15. The positioning seat 14 and the positioning rod 16 are used in conjunction to ensure that the clamps 17 are in a stable position during the clamping process. To ensure accurate positioning and avoid displacement or shaking of the pile, the hydraulic rod 23 is started, and the turning frame 4 is driven to turn over through its telescopic movement between the third rotating seat 21 and the fourth rotating seat 22. The support rod 5 inside the turning frame 4 enhances the structural strength of the turning frame 4, ensuring the safety and stability of the turning process. When the pile is turned to the desired position, the movement of the hydraulic rod 23 is stopped, and the second electric push rod 15 is started, so that its telescopic end drives the clamp 17 to move away from the pile to release the pile. If the direction of the pile needs to be changed, it can be achieved by rotating the rotating base 24.
