[0002] Piling operation for water conservancy construction is an important means of foundation treatment for infrastructure, and its application is becoming increasingly widespread. Currently, the piling equipment used in the infrastructure industry is mainly a pile driver.
[0003] During the use of the piling equipment for water conservancy construction, especially when drilling the ground, a relatively large amount of noise is usually generated. The main reason is that the friction between the pile body of the piling equipment and the soil is relatively large. When the pile body is driven or rotated into the soil layer with great force, the pile body and the surrounding soil experience intense friction and collision, resulting in the generation of mechanical vibration and sound waves. This friction not only increases the noise during the construction process, but also has a negative impact on the surrounding environment, the ecological system, and the health of construction personnel, especially when water conservancy facilities are constructed in urban or densely populated areas. The high noise level of piling operation often leads to discomfort in the surrounding environment and dissatisfaction among residents, and in some specific areas, the noise level may exceed the environmental protection standard, bringing pressure in terms of law and regulation. Therefore, how to reduce the noise generated by the piling equipment for water conservancy construction during the construction process, especially the friction noise generated during drilling and piling, has become an important challenge in current water conservancy engineering construction.

[0032] The vertical support plate 21 is arranged on the pile machine vehicle 1, a telescopic air cylinder 22 is fixedly connected to the inner wall of the vertical support plate 21, an connecting seat 23 is fixedly connected to the output shaft of the telescopic air cylinder 22, a driving motor 24 is fixedly connected to the top of the connecting seat 23, a drill bit 25 is fixedly connected to the output shaft of the driving motor 24, the drill bit 25 is used for drilling and piling, the connecting seat 23 is slidingly connected to the vertical support plate 21, and the pile machine vehicle 1 is used for moving construction.
[0033] The cooling mechanism 4 comprises a communication pipe 41 and a spring 46, one end of the communication pipe 41 is fixedly connected to the inner wall of the annular air bag 33, the other end of the communication pipe 41 is fixedly connected with a fixed square block 42, the inner wall of the fixed square block 42 is fixedly connected with one end of the spring 46, the other end of the spring 46 is fixedly connected with a guide column 43, the outer wall of the guide column 43 is piston-connected with the inner wall of the fixed square block 42, the inner wall of the guide column 43 is rotatably connected with a guide roller 44, the shaft of the guide roller 44 is fixedly connected with a fan 45, the outer wall of the fixed square block 42 is fixedly connected with the inner wall of the hollow block 32, the inner wall of the fixed square block 42 is communicated with the inner wall of the annular air bag 33 through the communication pipe 41, when the annular air bag 33 is in contact with the ground, the annular air bag 33 is compressed and deformed, the compressed air of the annular air bag 33 enters the fixed square block 42 through the communication pipe 41, so that high pressure is formed in the fixed square block 42, the high pressure in the fixed square block 42 drives the guide column 43 and the guide roller 44, so that the guide roller 44 is in contact with the drill bit 25, the cooling mechanism 4 is provided with three, and the three cooling mechanisms 4 are circumferentially arranged on the inner wall of the hollow block 32; the guide rollers 44 of the three cooling mechanisms 4 are in close contact with the drill bit 25 under the action of air pressure, further stabilizing and positioning the rotation of the drill bit 25.
[0034] The protection mechanism 5 comprises a power shaft 51, the power shaft 51 is fixedly connected to the output shaft of the driving motor 24, the bottom of the power shaft 51 is rotatably connected with the drill bit 25, a tapered groove 52 is formed in the inner wall of the drill bit 25, a sliding groove is formed in the inner wall of the power shaft 51, a spring 53 is arranged on the sliding groove of the power shaft 51, one end of the spring 53 is fixedly connected to the sliding groove of the power shaft 51, the other end of the spring 53 is fixedly connected with a tapered block 54, and the outer wall of the tapered block 54 is slidingly connected with the sliding groove of the power shaft 51.
[0035] The driving motor 24 is started to drive the drill bit 25 to rotate through the protection mechanism 5, and the connecting seat 23 and the driving motor 24 are driven by the telescopic air cylinder 22 to move downwards, so that the drill bit 25 moves downwards while rotating to pile.
[0036] When the output shaft of the driving motor 24 drives the power shaft 51 to rotate, the power shaft 51 drives the conical block 54 to rotate, and the conical block 54 is in contact with the conical groove 52 through the spring three 53, so that when the conical block 54 rotates, it also generates a circumferential force on the conical groove 52, driving the drill bit 25 to rotate, until the drill bit 25 encounters a large resistance, at which time the spring three 53 is compressed, causing the conical block 54 to shrink into the sliding groove of the power shaft 51, so that the conical block 54 cannot drive the conical groove 52 to rotate. Specifically, when working normally, the power shaft 51 drives the conical block 54 to transmit power to the drill bit 25 through the conical groove 52, allowing the drill bit 25 to rotate smoothly for piling, but if the drill bit 25 encounters an abnormally large resistance, such as hitting a hard rock or obstacle, the conical block 54 will automatically shrink under the action of the spring three 53 and slide into the sliding groove inside the power shaft 51, cutting off the continuous driving force to the drill bit 25, thereby protecting the drill bit 25 from being stuck or damaged, and also preventing the driving motor 24 from being burned out due to overload, which is equivalent to adding a mechanical overload protection function.
[0037] At this time, the connecting seat 23 drives the hollow block 32 to move downward through the spring one 31, until the hollow block 32 drives the annular air bag 33 to contact the ground, at which time the annular air bag 33 is compressed, and when the annular air bag 33 contacts the ground, it is compressed and deformed, causing the part drilled by the drill bit 25 to be covered, and the hollow block 32 plays a role in isolating noise. The annular air bag 33, as a flexible material, can absorb and buffer the vibration and impact force generated when the drill bit 25 contacts the ground, reducing the friction noise generated by drilling. The compression and flexibility of the annular air bag 33 can effectively block the propagation of sound waves and reduce the outward diffusion of noise, thereby reducing noise pollution in the surrounding environment. In this way, noise interference on the construction environment and surrounding residents can be reduced during piling operations, meeting the requirements of environmental protection and improving the sustainability and social acceptance of construction.
[0038] The compressed air in the annular air bag 33 enters the fixed square block 42 through the communication pipe 41, causing a high pressure to form in the fixed square block 42, which drives the guide column 43 and the guide roller 44, causing the three guide rollers 44 to be in annular contact with the drill bit 25, preventing the drill bit 25 from deviating from the target position or producing irregular vibrations during ground drilling, thereby improving the accuracy and efficiency of construction.
[0039] The guide roller 44 will be driven to rotate by the drill bit 25, the guide roller 44 drives the fan 45 to rotate, and the rotation of the fan 45 drives the air flow to cool the drill bit 25, which can effectively remove the heat around the drill bit 25, reduce the temperature of the drill bit 25, and thus maintain its stable working state, improve the service life and construction efficiency of the drill bit 25.
