Description

Technical Field

[0001] The utility model relates to the technical field of pile drivers, in particular to a base structure and a construction pile driver thereof. Background Art

[0002] During the construction of a construction site, it is necessary to drive piles into the ground. The pile body is mainly rammed into the ground by a counterweight hitting the pile head, and a huge noise will be generated during the impact process.

[0003] The prior art discloses a low-noise construction site pile driver (CN106522225B), which includes a base, a protective shell and a PLC controller. A bracket is fixed in the middle of the upper end of the base through a fixed cone. Lifting rods are arranged on both sides inside the bracket. The lower ends of the lifting rods are fixedly connected with fixed blocks, and a pile body is fixed between the fixed blocks. A partition is arranged outside the bracket, and sound-absorbing cotton is arranged between the partition and the protective shell. A hanging plate is arranged in the middle of the upper end of the protective shell, a counterweight is fixedly connected to the lower end of the hanging plate, and a rope fixing buckle is fixedly connected to the upper end of the hanging plate.

[0004] In the prior art, by setting a protective shell and laying sound-absorbing cotton inside the protective shell, the absorption of noise is realized to achieve the purpose of noise reduction. However, during the rapid descent of the counterweight, the air inside the protective shell will be pushed and flowed, and along with the impact sound wave, simply relying on the sound-absorbing surface to absorb the sound wave has limited effect, and there is room for optimization for the interference during the diffusion of the sound wave to the sound-absorbing cotton.

[0005] Therefore, we propose a base structure and a construction pile driver thereof. Summary of the Utility Model

[0010] An interference structure is provided on the inner wall surface of the second inner container to suppress the propagation of sound waves. The interference structure includes a first drainage pipe, a second drainage pipe, and evacuation holes. The second drainage pipe is fixedly connected to the first drainage pipe, and a sandwich layer is formed between the first drainage pipe and the second drainage pipe.

[0011] As a preferred embodiment of the present utility model, the substrate forms a hollow frustum structure. The tops of the first inner container and the second inner container are both fixedly connected to the inner top surface of the substrate. The sizes of the first inner container and the second inner container decrease uniformly, and the sound insulation cotton is fixedly installed on the inner wall surface of the substrate.

[0012] As a preferred embodiment of the present utility model, the interference structure further includes a valve. The valve is located in the sandwich layer and is fixedly connected to the first drainage pipe.

[0013] As a preferred embodiment of the present utility model, the interference structure further includes a spacer and a sealing plate. The same sealing plates are fixedly provided at both ends of the first drainage pipe. The sealing plates seal the sandwich layer, and the spacer is fixedly connected to the second drainage pipe.

The counterweight block is located in the cavity of the protective shell, and an avoidance groove is provided on the top surface of the protective shell for pulling the counterweight block to lift.

[0017] Beneficial effects

[0018] The present utility model provides a base structure and a construction pile driver thereof. The following beneficial effects are achieved:

[0019] 1. The base structure and its construction pile driver can reduce the diffusion of sound waves during the impact of the counterweight on the pile head by setting sound insulation cotton, the first inner liner and the second inner liner in the protective shell cavity to form a multi-layer structure, and reduce the noise during the piling process. For urban construction, it can reduce the interference to nearby residents. The evacuation holes need to be set near the second inner liner. When the sound waves spread to the inner wall of the second inner liner, part of the sound waves enter the cavity of the second drainage pipe, and then the sound waves propagate along the radial direction of the second drainage pipe. Part of the sound waves enter the evacuation holes, so as to interfere with and consume the diffusion of the sound waves. A number of identical first drainage pipes and second drainage pipes are arranged on the wall surface of the second inner liner to achieve the purpose of noise reduction.

[0020] 2. For the base structure and its construction pile driver, when the sound waves propagate in the second drainage pipe, the sound waves entering the interlayer will cause the air in the interlayer to vibrate. The vibrating air is buffered and absorbed by the rubber-like valve to achieve another noise reduction purpose. The setting of the spacer can make the interlayer form a partition, further improving the interference to the diffusion of the sound waves and having multiple noise reduction effects. After the sound waves passing through the second drainage pipe are absorbed by the sound insulation cotton, the energy of the sound waves is greatly reduced.

[0021] 3. For the base structure and its construction pile driver, by setting the above base structure, the noise of the whole device is at a relatively low level during the construction process, reducing the interference of the huge noise during the piling process to the nearby residents.

Detailed Description of the Preferred Embodiments

[0028] A base structure and its construction pile driver, as shown in Figure 1 and Figure 2As shown, it includes:

[0029] A substrate 10, a plate-like structure for support, with a protective shell 11 fixedly arranged on the top surface of the substrate 10. The protective shell 11 and the substrate 10 together form a sealed chamber;

[0030] As Figure 1 and Figure 2 As shown, a shielding structure is arranged in the cavity of the protective shell 11 for suppressing the propagation of sound waves. The shielding structure includes sound insulation cotton 12, a first inner tank 13 and a second inner tank 14. The sound insulation cotton 12 is fixedly connected to the protective shell 11, the first inner tank 13 is fixedly connected to the sound insulation cotton 12, and the second inner tank 14 is fixedly connected to the first inner tank 13. A first slit cavity is formed between the second inner tank 14 and the first inner tank 13, and a second slit cavity is formed between the first inner tank 13 and the sound insulation cotton 12. The substrate 10 forms a hollow frustum structure. The tops of the first inner tank 13 and the second inner tank 14 are both fixedly connected to the inner top surface of the substrate 10. The sizes of the first inner tank 13 and the second inner tank 14 decrease uniformly. The sound insulation cotton 12 is fixedly installed on the inner wall surface of the substrate 10. In this solution, the sound insulation cotton 12 is a corrugated sponge. By arranging the sound insulation cotton 12, the first inner tank 13 and the second inner tank 14 in the cavity of the protective shell 11 to form a multi-layer structure, the diffusion of sound waves during the process of the counterweight hitting the pile head can be reduced, and the noise during the piling process can be reduced. For construction in urban areas, the interference to nearby residents can be reduced;

[0031] As shown in 3, Figure 4 and Figure 5 As shown, an interference structure is arranged on the wall surface of the second inner tank 14 for suppressing the propagation of sound waves. The interference structure includes a first drainage pipe 20, a second drainage pipe 21 and evacuation holes 22. The second drainage pipe 21 is fixedly connected to the first drainage pipe 20. A sandwich is formed between the first drainage pipe 20 and the second drainage pipe 21. A number of evacuation holes 22 are opened on the wall surface of the second drainage pipe 21, and the evacuation holes 22 communicate with the sandwich. The interference structure further includes a valve 23, and the valve 23 is located in the sandwich and fixedly connected to the first drainage pipe 20. In this solution, the evacuation holes 22 need to be arranged near the second inner tank 14. When the sound waves spread to the inner wall of the second inner tank 14, part of the sound waves enter the cavity of the second drainage pipe 21, and then the sound waves propagate along the radial direction of the second drainage pipe 21. Part of the sound waves enter the evacuation holes 22, so as to interfere with and consume the diffusion of the sound waves. A number of the same first drainage pipes 20 and second drainage pipes 21 are arranged on the wall surface of the second inner tank 14 to achieve the purpose of noise reduction.

[0032] As Figure 5As shown, the interference structure further includes a spacer 24 and a sealing plate 25. Sealing plates 25 of the same structure are fixedly arranged at both ends of the first drainage tube 20. The sealing plates 25 seal the interlayer. The spacer 24 is fixedly connected to the second drainage tube 21. Both the first drainage tube 20 and the second drainage tube 21 are of circular tube structure. The first drainage tube 20 penetrates through the second inner tank 14 and extends to one side of the first inner tank 13. The sealing plate 25 is of annular structure. The outer wall of the sealing plate 25 is fixedly connected to the inner wall of the first drainage tube 20, and the inner wall of the sealing plate 25 is fixedly connected to the outer wall of the second drainage tube 21. The valve 23 is an annular rubber sheet, and the valve 23 is fixedly connected to the inner wall of the first drainage tube 20 and the outer wall of the second drainage tube 21. The valve 23 and the evacuation hole 22 are respectively close to both ends of the second drainage tube 21. The spacer 24 forms a frustum structure, and the smaller end face of the spacer 24 faces the valve 23. As a supplementary explanation of the above solution, when sound waves propagate in the second drainage tube 21, the sound waves entering the interlayer will cause the air in the interlayer to vibrate. The rubber-textured valve 23 buffers and absorbs the vibrating air, achieving another noise reduction purpose. The setting of the spacer 24 can make the interlayer form a partition, further improving the interference with the diffusion of sound waves and having a multiple noise reduction effect. After the sound waves passing through the second drainage tube 21 are absorbed by the sound insulation cotton 12, the energy of the sound waves is greatly reduced.

[0033] Not shown in the figure, a construction pile driver includes a lifter. A counterweight is provided at the output end of the lifter. The following all base structures are provided below the lifter. The lifter is fixedly installed on the top of the substrate 10. The counterweight is located in the cavity of the protective shell 11. An avoidance groove is provided on the top surface of the protective shell 11 for pulling the counterweight up and down. Of course, it should also be used in cooperation with a controller. The controller can be a PLC controller, and the lifter can be a winch. A limiting rod should also be installed in the protective shell 11 to limit the counterweight to maintain linear sliding. The cable on the winch passes through the avoidance groove and is connected to the counterweight to realize pile driving. The specific control method can refer to (Publication No.: CN106522225B), which will not be elaborated here;

[0034] By setting the above base structure, the noise of the whole device is at a relatively low level during the construction process, reducing the interference of the huge noise during pile driving on the nearby residents.

[0035] Working principle of the present utility model: By arranging sound insulation cotton 12, a first inner liner 13 and a second inner liner 14 in the cavity of the protective shell 11 to form a multi-layer structure, the diffusion of sound waves during the impact of the counterweight on the pile head can be reduced. The evacuation holes 22 need to be arranged close to the second inner liner 14. When the sound waves diffuse to the inner wall of the second inner liner 14, part of the sound waves enter the cavity of the second drainage pipe 21, and then the sound waves propagate along the radial direction of the second drainage pipe 21. Part of the sound waves enter the evacuation holes 22, thereby achieving the interference and consumption of the diffusion of sound waves. A number of identical first drainage pipes 20 and second drainage pipes 21 are arranged on the wall surface of the second inner liner 14. When the sound waves propagate in the second drainage pipe 21, the sound waves entering the interlayer will cause the air in the interlayer to vibrate. The rubber-textured valve 23 buffers and absorbs the vibrating air, achieving another noise reduction purpose. The arrangement of the spacer 24 can make the interlayer form a partition, further improving the interference with the diffusion of sound waves and having a multiple noise reduction effect.
