[0022] Specifically, the connecting seat 7 and the fixing block 8 are connected through bolts passing through, and the buffer spring 5 is fixed inside the connecting seat 7 and the pile cap main body 3 by brazing.

[0023] By adopting the above technical solution, the use quality of the buffer spring 5 is ensured, and the use strength of the equipment is ensured.

[0024] Specifically, a fixing steel plate is arranged in the middle inside the pile cap main body 3, and an installation cavity is arranged at the bottom end inside the pile cap main body 3.

[0025] By adopting the above technical solution, the stability and firmness of the installation of the pile cap main body 3 are ensured, and the use quality is guaranteed.

[0026] Specifically, a buffer pad is arranged on the bottom surface of the fixing steel plate.

[0027] By adopting the above technical solution, the buffer effect between the pile cap main body 3 and the pile body is strengthened, and the protection quality of the pile body is improved.

[0028] When this embodiment is in use: When the pile hammer of the pile driver drops, the pile hammer hits the installation cover 1 and makes it move downward. At the same time, the fixing sleeve 9 moves downward along the inner wall of the damping sleeve 2, the connecting seat 7 at the bottom end of the fixing block 8 moves downward along the inside of the damping sleeve 6, and the buffer spring 5 is compressed by the force. When the installation cover 1 contacts the pile cap main body 3, the impact force can be transmitted to the pile body. When the pile hammer moves upward, the buffer spring 5 resets to push the connecting seat 7 and the installation cover 1 above it up again for the next buffer, ensuring the use effect of the pile cap main body 3 and reducing the vibration of the pile body and the noise generated by pile driving.

[0029] Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is: Specifically, the limiting and abutting component 4 includes a threaded hole 41, an abutting block 42, a sliding block 43, a limiting spring 44 and a guiding seat 45.

[0034] In the use of this embodiment: when the pile driver is in use, the pile cap main body 3 can be installed at the upper end of the pile head to protect it. Adjust the pile cap main body 3 to the pile top, then pull the sliding block 43 to compress the limit spring 44, and then fix the pile cap main body 3 by passing a bolt through the threaded hole 41. Release the sliding block 43 to make the limit spring 44 reset, and at the same time, the abutting block 42 abuts against the nut of the bolt to position it, preventing the bolt from loosening during the pile driving process and causing the pile cap main body 3 to become loose, improving the stability and firmness of the equipment during use and ensuring the installation strength.

[0035] The working principle and usage process of the present utility model: when the present utility model is in use, when the pile driver is in use, the pile cap main body 3 can be installed at the upper end of the pile head to protect it. Adjust the pile cap main body 3 to the pile top, then pull the sliding block 43 to compress the limit spring 44, and then fix the pile cap main body 3 by passing a bolt through the threaded hole 41. Release the sliding block 43 to make the limit spring 44 reset, and at the same time, the abutting block 42 abuts against the nut of the bolt to position it, preventing the bolt from loosening during the pile driving process and causing the pile cap main body 3 to become loose, improving the stability and firmness of the equipment during use and ensuring the installation strength;

[0036] When the pile hammer of the pile driver drops, the pile hammer impacts the mounting cover 1 and makes it move downward. At the same time, the fixed sleeve 9 moves downward along the inner wall of the damping sleeve 1, and the connecting seat 7 at the bottom end of the fixed block 8 moves downward along the inside of the damping sleeve 2, and the buffer spring 5 is compressed under force. When the mounting cover 1 contacts the pile cap main body 3, the impact force can be transmitted to the pile body. When the pile hammer moves upward, the buffer spring 5 resets to push the connecting seat 7 and the mounting cover 1 above it up again for the next buffering, ensuring the usage effect of the pile cap main body 3, reducing the vibration of the pile body and the noise generated by pile driving.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
