[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-3 As shown, a silencer device for a pile driver used in engineering construction includes a pile driver component 1, the pile driver component 1 includes a silencer component 2 sleeved on the outside, the pile driver component 1 can be driven to maintain vertical reciprocating motion and axial rotation along the silencer component 2, the silencer component 2 is provided with buffer mechanisms distributed in a circular array, the inner wall of each buffer mechanism is fitted and abutted with a buffer block 208, and the buffer block 208 is filled with silencer cotton 209.

[0026] The main purpose of the pile driver silencer for engineering construction is to silence the pile driving work to the greatest extent through the silencer cotton 209 filled in the buffer block 208 and the second springs 210 arranged in an array inside, and the buffer block 208 fits the sleeve rod 201 close to the pile column 101, and the silencer outer shell 204 slides downward along the sleeve rod 201 to abut against the ground; the buffer block 208 is also abutted by the first springs 206 distributed in a circular array inside the silencer inner groove 205 and the abutment block 207 arranged at the end of the first spring 206, so as to buffer and unload the force through the elasticity of the first spring 206 and the second spring 210.

[0027] In the technical solution provided by this utility, Figure 1 and Figure 2 It can be seen that the pile driver assembly 1 includes a pile driving column 101, and a pile driving head 102 is provided at the bottom of the pile driving column 101 for performing pile driving work.

[0028] In the technical solution provided by this utility, Figure 1 , Figure 2 and Figure 3 It can be seen that the silencer assembly 2 includes a sleeve rod 201 sleeved on the outer wall of the pile driver assembly 1, and the inner wall of the sleeve rod 201 is provided with a rotation groove 202 to maintain axial rotation around the pile driver assembly 1. The pile driver assembly 1 inside the sleeve rod 201 can be axially rotated, thereby facilitating the pile driving and drilling work.

[0029] Furthermore, a slide groove 203 is provided on the outer wall of the sleeve rod 201, so that the silencer shell 204 slidably arranged on the outer wall of the sleeve rod 201 can slide vertically. The slide groove 203 is equipped to drive the silencer shell 204 to maintain vertical reciprocating motion, so that the silencer shell 204 abuts against the ground, thereby blocking the space between the ground end of the pile driver component 1 and the outside world, avoiding the noise of the pile driving work from being transmitted, and performing the silencer work.

[0030] Furthermore, a silencer inner groove 205 is provided inside the silencer outer shell 204, and a buffer mechanism is arranged in a circular array inside the silencer inner groove 205. The buffer mechanism specifically includes first springs 206 distributed in an array and arranged in a circular array in the silencer inner groove 205 away from the inner wall of the pile driver assembly 1, and each first spring 206 is provided with an abutment block 207 at the end close to the pile driver assembly 1. The buffer block 208 can be abutted by the abutment block 207, thereby abutting the silencer inner groove 205. Then, through the elasticity of the first spring 206, the rebound force exerted on the pile driver assembly 1 during the pile driving operation can be elastically relieved, thereby preventing the force exerted on the pile driver assembly 1 from being unable to be discharged outwards and causing damage due to long-term use.

[0031] Furthermore, each abutment block 207 is provided with a buffer block 208 away from the outer wall of the first spring 206, and the interior of the buffer block 208 is provided with a second spring 210 distributed in an array, which can make the buffer block 208 full of elasticity, thereby relieving the unloading force and performing noise reduction. The noise reduction work can be further performed by the noise reduction cotton 209 filled inside.

[0032] Furthermore, the bottom of the silencer shell 204 is provided with fixing blocks 211 distributed in a circular array, and the side profile of the fixing blocks 211 is specifically triangular. When the silencer shell 204 abuts against the ground, the fixing blocks 211 with a triangular side profile can be used to fix the silencer shell 204 to avoid axial rotation.

[0033] Working principle: First, align the pile driver assembly 1 with the desired pile driving range for insertion, then slide the silencer housing 204 downward through the slide slot 203, and insert it into the ground through the fixing blocks 211 at the bottom, thereby assisting the pile driver assembly 1 to work steadily;

[0034] Then the pile driving column 101 is driven to rotate axially to perform pile driving. During the pile driving, an abutment block 207 is provided at the end of each first spring 206 close to the pile driver assembly 1. The abutment block 207 can abut the buffer block 208, thereby abutting the silencer inner groove 205. The elasticity of the first spring 206 can elastically relieve the rebound force of the pile driver assembly 1 during the pile driving, thereby preventing the pile driver assembly 1 from being damaged due to the inability to discharge the force outwards and long-term use.

[0035] The buffer block 208 is also provided with second springs 210 distributed in an array, so that the buffer block 208 can be full of elasticity, thereby relieving the unloading force and performing noise reduction. The noise reduction work can be further performed by the noise reduction cotton 209 filled inside.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
