[0002] A hammer pile driver is a commonly used pile driving equipment. It uses a mechanical device to drop a heavy hammer from a certain height, and the impact force of the hammer drives the pile into the ground.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a clamp-type hydraulic hammer pile driver, including a mounting frame 1. A fixed column 2 is fixedly connected inside the mounting frame 1. A hydraulic cylinder 3 is fixedly connected to the lower surface of the mounting frame 1. A sliding column 8 is fixedly connected to the output end of the hydraulic cylinder 3. The sliding column 8 slides on the outer wall of the fixed column 2. A support frame 5 is fixedly connected to the bottom end of the fixed column 2. An installation block 9 is fixedly connected to the outer wall of the sliding column 8. A fixed block 4 is fixedly connected to the outer wall of the installation block 9. A support assembly is provided inside the support frame 5 to enhance the stability of the overall structure. The support assembly includes a support rod 1 6. The outer wall of the support rod 1 6 is fixedly connected to the inside of the right side of the support frame 5. A support rod 2 7 is fixedly connected to the inside of the left side of the support frame 5.
[0026] Specifically, mounting frame 1 is used to support and fix fixed column 2, support frame 5 is used to fix support rod 1 6 and support rod 2 7, fixed column 2 is used to support sliding column 8 and mounting block 9, and hydraulic cylinder 3 is used to drive fixed block 4, sliding column 8 and mounting block 9 to move up and down. This allows the hydraulic hammer itself not to bear excessive pressure and load, reduces the wear and damage risk of the hydraulic hammer, extends the service life of the hydraulic hammer, and reduces the cost and time of equipment maintenance and replacement.
[0027] Reference Figure 3 and Figure 4 A motor 10 is fixedly connected to the lower interior of the fixed block 4. A bevel gear 11 is fixedly connected to the output end of the motor 10. A bevel gear 12 is meshed with the tooth end of the bevel gear 11. A threaded rod 13 is threadedly connected to the inside of the bevel gear 12. The outer walls of the bevel gear 12 and the threaded rod 13 are rotatably connected inside the fixed block 4.
[0028] Specifically, the fixing block 4 is used to fix the motor 10, the motor 10 is used to drive the first bevel gear 11 to rotate, the first bevel gear 11 is used to drive the second bevel gear 12 to rotate, the fixing block 4 is used to support the second bevel gear 12 to rotate inside it, the rotation of the second bevel gear 12 is used to drive the threaded rod 13 to rotate, and the rotation of the threaded rod 13 will drive the connecting column 14 to rotate inside the extrusion block 16.
[0029] Reference Figure 4 and Figure 5 A connecting post 14 is fixedly connected to the right outer wall of the threaded rod 13, and a limiting post 18 is slidably connected inside the fixing block 4; a squeezing block 16 is fixedly connected to the right outer wall of the limiting post 18, and an installation groove 17 is opened inside the squeezing block 16; a limiting block 15 is fixedly connected to the right outer wall of the connecting post 14, and the outer wall of the limiting block 15 is set inside the installation groove 17.
[0030] Specifically, the connecting column 14 is used to drive the limiting block 15 to rotate inside the mounting groove 17, the limiting column 18 is used to support the squeezing block 16 to slide, and prevent the squeezing block 16 from shifting position during use. The squeezing block 16 is used to fix the hydraulic hammer, so as to meet the needs of different pile types and pile diameters. Smaller pile diameters may be suitable for finer hydraulic hammers for precise striking, while larger pile diameters require thicker hydraulic hammers to provide greater striking force to ensure the sinking effect of the pile.
[0031] Working principle: When a clamp-type hydraulic hammer pile driver is needed, starting the motor 10 drives the bevel gear 11 to rotate. The rotation of the bevel gear 11 drives the bevel gear 12 to rotate, which in turn moves the threaded rod 13. The movement of the threaded rod 13 moves the connecting column 14 and the clamping block 16. Finally, the clamping block 16 clamps the hydraulic hammer, thus meeting the needs of different pile types and diameters. Smaller pile diameters may be suitable for finer hydraulic hammers for precise driving, while larger diameter piles require thicker hydraulic hammers to provide greater striking force to ensure the pile sinking effect. Starting the hydraulic cylinder 3 drives the fixing block 4 and the mounting block 9. By moving the hydraulic hammer up and down, it is possible to reduce the pressure and load on the hydraulic hammer itself, thereby reducing the risk of wear and damage, extending its service life, and reducing the cost and time of equipment maintenance and replacement. This clamp-type hydraulic hammer pile driver can not only meet the needs of different pile types and diameters—smaller pile diameters may be suitable for finer hydraulic hammers for precise driving, while larger diameter piles require thicker hydraulic hammers to provide greater striking force to ensure the pile sinking effect—but also reduces the pressure and load on the hydraulic hammer itself, thereby reducing the risk of wear and damage, extending its service life, and reducing the cost and time of equipment maintenance and replacement.
