[0001] The utility model belongs to the technical field of vibroflot, and specifically relates to a high-power vibroflot for deep stratum foundation treatment. Background Technique

[0002] The upper part of the vibroflot is a motor, and the lower part is a vibrating body. When the motor rotates, it drives the shaft of the vibrating body to rotate through an elastic coupling. An eccentric block is installed on the shaft to generate a horizontal vibration force.

[0003] When installing the vibroflot, it is positioned on a long-distance guide rod, and then the guide rod is suspended on the crane arm. The vibration generated by the vibroflot during construction will be transmitted to the guide rod and the crane arm. The greater the vibration of the guide rod, the greater the danger to the crane.

[0004] Therefore, we propose a high-power vibroflot for deep stratum foundation treatment to solve the existing problems. Content of the Utility Model

The vibration generated by the vibroflot during construction will be transmitted to the guide rod and the crane arm. The greater the vibration of the guide rod, the greater the danger to the crane as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a high-power vibroflot for deep stratum foundation treatment, including a housing, a chassis and a feed pipe. The housing and the chassis form the vibroflot body. An eccentric component is rotatably arranged inside the housing. A hollow motor is arranged inside the chassis.

The guide rod is suspended on the crane through structures such as steel wires. At this time, control the vibroflot to move downwards. The hollow motor works to drive the eccentric assembly to rotate, thereby generating a horizontal vibration force to perform hole-making treatment on the specified surface. Through the coaxial hollow design everywhere, the medium water and the medium sand material directly fall from the central axis of the vibroflot into the hole to complete the sand filling operation;

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: a high-power vibroflot for deep stratum foundation treatment, including a housing 1, a chassis 2 and a feeding pipe 4. The housing 1 and the chassis 2 form the vibroflot body. An eccentric assembly is rotatably arranged inside the housing 1. A hollow motor 8 is arranged inside the chassis 2. The hollow motor 8 drives the eccentric assembly. A vibration damping assembly is arranged on the upper surface of the chassis 2. The vibration damping assembly, the eccentric assembly and the hollow motor 8 are in a coaxial state and a through hole is arranged at the axis. At this time, the high-power vibroflot body for deep stratum foundation treatment moves downward, and the eccentric assembly rotates to generate a horizontal vibration force to perform hole-making treatment on the specified surface. Through the coaxial hollow design everywhere, the medium water and the medium sand material directly fall from the central axis of the vibroflot into the hole for sand filling operation. During the vibration of the vibroflot, through the design of the vibration damping assembly, most of the vibration force transmitted to the connecting column 5 can be absorbed and buffered and released. The feeding pipe 4 is movably inserted into the central axis hole of the connecting column 5, and the bottom end of the feeding pipe 4 extends into the central axis hole of the hollow motor 8, and the material enters the coaxial hole along the feeding pipe 4.

[0025] The eccentric assembly is composed of a shaft head 11, an eccentric block 12, a shaft rod 13 and a shaft seat 14. The shaft head 11 is rotatably arranged at the top of the housing 1. The shaft rod 13 is arranged at the bottom of the shaft head 11. The shaft seat 14 is arranged at the bottom of the shaft rod 13. The shaft seat 14 is rotatably arranged at the bottom end of the inner wall of the housing 1. The top end of the shaft head 11 is fixed on the output end of the hollow motor 8. When the hollow motor 8 works, the shaft rod 13 is driven by the shaft head 11 to rotate on the shaft seat 14. Through the design of the eccentric block 12, the high-power vibroflot body for deep stratum foundation treatment vibrates.

[0026] The shock-absorbing component is composed of a buffer shell 3, a connecting column 5, a steel plate rubber ring 9, and a steel plate rubber plug 10. The buffer shell 3 is arranged on the upper surface of the chassis 2 through a positioning component. The steel plate rubber ring 9 is arranged on the inner wall of the buffer shell 3. The steel plate rubber plug 10 is slidably arranged on the inner wall of the steel plate rubber ring 9. The connecting column 5 is arranged on the inner wall of the steel plate rubber plug 10. The inner diameter of the top opening of the buffer shell 3 is smaller than the diameter of the steel plate rubber plug 10. Through the soft contact design of the steel plate rubber ring 9 and the steel plate rubber plug 10, most of the vibration force transmitted to the connecting column 5 can be absorbed and buffer-released.

[0027] The positioning component is composed of a flange 6 and mounting bolts 7. The flange 6 is fixed on the lower surface of the buffer shell 3. Each mounting bolt 7 is inserted into the flange 6 and thread-fixed on the upper surface of the chassis 2. Through the design of the positioning component and the sliding contact design of the steel plate rubber ring 9 and the steel plate rubber plug 10, the shock-absorbing component can be conveniently disassembled and replaced.

[0028] Working principle: When it is necessary to use a high-power vibroflot for deep stratum foundation treatment, the guide rod can be fixed to the top of the connecting column 5. The guide rod is hung on a crane through structures such as steel wires. At this time, control the vibroflot to move downwards. The hollow motor 8 works to drive the eccentric component to rotate, thereby generating a horizontal vibration force to perform hole-making treatment on the specified surface. Through the coaxial hollow design everywhere, the medium water and medium sand material directly fall from the central axis of the vibroflot into the hole for sand filling operation;

[0029] At the same time, during the vibration of the vibroflot, through the soft contact design of the steel plate rubber ring 9 and the steel plate rubber plug 10, most of the vibration force transmitted to the connecting column 5 can be absorbed and buffer-released. Through the design of the positioning component and the sliding contact design of the steel plate rubber ring 9 and the steel plate rubber plug 10, the shock-absorbing component can be conveniently disassembled and replaced.

[0030] It should be noted that the structure of the hollow motor 8 is an existing mature technology, and its working principle and internal structure are known to those skilled in the art of this technical field. The present utility model only utilizes its function and does not improve its internal structure. Therefore, it will not be described in detail here. Those skilled in the art can make any selection according to their needs or convenience.

[0031] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
