Description

Technical Field

[0001] This utility model relates to the field of pipe pile manufacturing, and in particular to a pipe pile centrifuge. Background Technology

[0002] In the field of pipe pile production and manufacturing, the pipe pile centrifuge is the core equipment for achieving dense molding of concrete pipe piles. Its operating effect directly determines the key performance of pipe piles such as structural strength and durability. As a commonly used foundation component in construction engineering, pipe piles are widely used in housing construction, bridges, municipal engineering and other scenarios, and have an important impact on the overall stability of the project.

[0003] In the current use of pipe pile centrifuges, once the pipe pile jumps, the resulting vibration will be directly transmitted to the entire equipment. This problem will not only aggravate the wear of transmission components such as rollers and bearings and shorten the service life of the equipment, but also form a vicious cycle of jumping and vibration. The vibration of the equipment itself will further amplify the jumping amplitude of the pipe pile, causing the offset of the pipe pile mold to increase continuously. In severe cases, it may even cause the mold to fall off, posing a great safety hazard to the production process. Utility Model Content

[0023] As attached Figure 1 To be continued Figure 4As shown: A pipe pile centrifuge includes a base plate 13 and a pipe pile mold 12. A fixing block 3 is fixedly connected to one side of the base plate 13. A first rotating shaft 4 is rotatably connected to the upper surface of the fixing block 3 via a bearing. A turntable 5 is fixedly connected to the upper surface of the first rotating shaft 4. A first slide rail 17 is formed on the upper surface of the fixing block 3. A first slider 19 is slidably connected inside the first slide rail 17. Multiple support columns 20 are fixedly connected to the upper surface of the first slider 19. The upper surface of each support column 20 is fixedly connected to the bottom surface of the turntable 5. A support rod 6 is fixedly connected to the upper surface of the turntable 5. A cylinder 9 is fixedly connected to the outer surface of the support rod 6. A moving plate 8 is fixedly connected to the output end of the cylinder 9. Two sets of mounting frames 10 are fixedly connected to the bottom surface of the moving plate 8. An auxiliary wheel 7 is rotatably connected to the interior of each set of mounting frames 10 via a bearing. A first track 1 adapted to the auxiliary wheel 7 is fixedly connected to the outer surface of the pipe pile mold 12. 1. A first fixed frame 1 is fixedly connected to the bottom surface of the fixed block 3. A first motor 2 is fixedly connected inside the first fixed frame 1. The output end of the first motor 2 is fixedly connected to the bottom surface of the first rotating shaft 4 through a reducer. When the first motor 2 is started, its output end drives the first rotating shaft 4 to rotate through the reducer. Since the first rotating shaft 4 is fixedly connected to the turntable 5, the turntable 5 rotates synchronously with the first rotating shaft 4. At the same time, the third motor 28 is started. The output end of the third motor 28 directly drives the second rotating shaft 33 to rotate, which in turn drives the active wheel 34 on the outer surface of the second rotating shaft 33 to rotate. The cylinder 9 is started. The output end of the cylinder 9 pushes the moving plate 8 to move downward. The moving plate 8 drives the two sets of mounting frames 10 and the auxiliary wheel 7 in the mounting frame 10 to move downward synchronously until the auxiliary wheel 7 is tightly attached to the first track 11 on the outer surface of the pipe pile mold 12, forming a radial limit on the pipe pile mold 12 and restricting the radial displacement of the pipe pile mold 12 during the centrifugal process.

[0024] The upper surface of the base plate 13 has three second slide rails 29, and each of the three second slide rails 29 has a second slider 31 slidably connected inside. The upper surfaces of the three second sliders 31 are all fixedly connected to a connecting plate 32. The inner wall of one of the second slide rails 29 is rotatably connected to a lead screw 23 via a bearing. The outer surface of the lead screw 23 is threadedly connected to the outer surface of one of the second sliders 31. The outer surface of the base plate 13 is fixedly connected to a second fixing frame 21, and the interior of the second fixing frame 21 is fixedly connected to a second motor 22. The output end of 2 is fixedly connected to one end of the lead screw 23 via a reducer. When it is necessary to adapt to different specifications of pipe pile mold 12, the second motor 22 is started. The output end of the second motor 22 drives the lead screw 23 to rotate via the reducer. The lead screw 23 is threadedly engaged with the corresponding second slider 31, which drives the second slider 31 to slide along the second slide rail 29, thereby driving the connecting plate 32, the first fixed plate 18, the second rotating shaft 33 and the driving wheel 34 to move as a whole. The distance between the driving wheel 34 and the driven wheel 26 is adjusted to adapt to pipe pile mold 12 of different lengths.

[0025] Three first fixing plates 18 are fixedly connected to the upper surface of the connecting plate 32. The outer surfaces of the three first fixing plates 18 are rotatably connected to a second rotating shaft 33 via bearings. Two drive wheels 34 are fixedly connected to the outer surface of the second rotating shaft 33. A third fixing frame 30 is fixedly connected to one side of the connecting plate 32. A third motor 28 is fixedly connected inside the third fixing frame 30. The output end of the third motor 28 is fixedly connected to one end of the second rotating shaft 33. Three second fixing plates 25 are fixedly connected to the upper surface of the base plate 13. The outer surface of the second fixed plate 25 is rotatably connected to the third rotating shaft 27 via bearings. The outer surface of the third rotating shaft 27 is fixedly connected to the driven wheel 26. The pipe pile mold 12 is placed above the driving wheel 34 and the driven wheel 26. The second track 24 on the outer surface of the pipe pile mold 12 is in contact with the driving wheel 34 and the driven wheel 26. When the driving wheel 34 rotates, it drives the pipe pile mold 12 to rotate through the friction with the second track 24. The driven wheel 26 rotates synchronously with the rotation of the pipe pile mold 12, providing stable support and auxiliary transmission for the pipe pile mold 12.

[0026] Two second tracks 24, which are adapted to the driving wheel 34 and the driven wheel 26, are fixedly connected to the outer surface of the pipe pile mold 12. Four support legs 14 are fixedly connected to the bottom surface of the base plate 13. Mounting plates 15 are fixedly connected to the bottom surface of each of the four support legs 14. Multiple fixing holes 16 are opened on the upper surface of each of the four mounting plates 15. The pipe pile mold 12 rotates at high speed under the drive of the driving wheel 34 to achieve centrifugal compaction of concrete. During the process, the fit structure between the auxiliary wheel 7 and the first track 11 can buffer the vibration impact of the pipe pile mold 12 and reduce the transmission of vibration to the base plate 13, support legs 14 and other components. At the same time, the support column 20 under the turntable 5 cooperates with the first slider 19 to further improve the stability of the equipment operation and ensure the safe and efficient centrifugal operation.

[0027] Working principle: When this pipe pile centrifuge is working, the first motor 2 is started first. Its output end drives the first rotating shaft 4 to rotate through the reducer. The turntable 5, which is fixed to the first rotating shaft 4, rotates accordingly. The first slider 19, which is connected to the support column 20 below the turntable 5, slides along the first slide rail 17 on the fixed block 3, providing stable support for the turntable 5. Then, the third motor 28 is started to drive the second rotating shaft 33 and the two driving wheels 34 on the outer surface to rotate. The pipe pile mold 12 is placed on the driving wheel 34 and the driven wheel 26. The two second tracks 24 on its outer surface are in contact with the driving wheel 34 and the driven wheel 26. 34 drives the pipe pile mold 12 to rotate through friction, realizing the centrifugal operation foundation transmission. Then, the cylinder 9 is started, and its output end pushes the moving plate 8 to move down, causing the auxiliary wheels 7 in the two sets of mounting frames 10 to press against the first track 11 of the pipe pile mold 12 to form a radial limit. If it is necessary to adapt to different specifications of pipe pile mold 12, the second motor 22 is started to drive the lead screw 23 to rotate, so that the second slider 31 threadedly connected to it slides along the three second slide rails 29, driving the connecting plate 32 and the drive wheel 34 to adjust the spacing. At the same time, the auxiliary wheel 7 cooperates with the first track 11 to buffer vibration and ensure stable operation of the equipment.
