Description

Technical Field

[0001] This utility model relates to the field of foundation treatment equipment technology, specifically a vibratory compactor with a modular vibratory compactor head. Background Technology

[0002] Vibro-compactors, as key equipment in vibro-compacting construction for foundation treatment, play a vital role in engineering construction. Traditional vibro-compactors are mostly of monolithic construction; however, this presents several drawbacks in practical applications. Firstly, when components such as the casing or vibro-compacting mechanism are damaged, repair or replacement requires operation of the entire device, which is not only difficult and costly but also time-consuming, severely slowing down project progress. Secondly, the adjustment of vibro-compacting parameters, such as vibration force and hole depth adaptability, is limited by the overall structure, making it difficult to flexibly address the diverse performance requirements of different soil types and construction techniques. Furthermore, vibration transmission interference is a significant problem; vibrations generated by the submersible motor are easily transmitted to the casing, affecting equipment stability and service life. The frictional losses during the rotation of the vibro-compacting mechanism are also high, reducing the reliability and efficiency of equipment operation. Therefore, developing vibro-compactors with modularity, ease of maintenance, adjustable parameters, and stable operation has become an urgent need for the industry.

[0003] The existing vibratory compactors still have the following problems when in use: the maintenance process is cumbersome, because due to the integral structure, the damage to a small part also requires the whole to be affected, which increases the maintenance cost and time; the parameter adjustment lacks flexibility, and it is impossible to quickly adjust key parameters such as vibration force according to different construction scenarios; the equipment operation stability is poor, and vibration transmission and rotational friction affect the equipment life and construction effect.

[0005] To address the shortcomings of existing technologies, this invention provides a vibratory punch with a modular vibratory punch head, solving the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vibratory punch with a modular vibratory punch head, comprising a housing assembly and a vibratory punching mechanism; wherein, the housing assembly includes a combined housing, an assembly groove, and a rotating seat; the vibratory punching mechanism includes a threaded pipe connection, a rotary joint, a water jet pipe, a hollow shaft, a connecting block, an eccentric block, a shock-absorbing support, a submersible motor, a pulley, and a transmission belt.

[0008] As a further embodiment of this utility model: the combined shell is a multi-segment modular structure, and each segment is adapted and spliced ​​by flange connection, snap-fit ​​splicing or threaded connection. The upper and lower ends of the inner wall of the combined shell are provided with assembly grooves, and rotating seats are installed inside the assembly grooves.

[0010] As a further embodiment of this utility model: the submersible motor is installed in the combined housing through a shock-absorbing support. The output end of the submersible motor, pulley, and transmission belt constitute a transmission mechanism to drive the hollow shaft and eccentric block to rotate. The eccentric block is assembled with the hollow shaft through a connecting block, and the eccentric block is a replaceable structure. It is connected by bolts or pins, and eccentric blocks of different masses and eccentricities can be replaced according to construction needs to adjust the vibration force parameters.

[0011] As a further improvement of this utility model: the assembly of the rotating seat and the assembly groove of the combined housing is a bearing fit or a self-lubricating bushing fit, which ensures the stability and low friction of the vibratory impact mechanism during rotation; the shock-absorbing support adopts rubber shock-absorbing pads, spring shock absorbers or composite shock-absorbing structures to reduce the vibration transmitted to the combined housing during the operation of the submersible motor and improve the stability of the equipment; the two pulleys are respectively fixedly connected to the top output end of the submersible motor and sleeved on the outside of the hollow shaft, and the transmission mechanism composed of the pulleys and the transmission belt is equipped with tension adjustment components, such as tensioning wheels and adjusting bolts, to adjust the tension of the transmission belt and ensure transmission efficiency and stability.

[0014] 2. In this utility model, by using replaceable eccentric blocks in combination with different connection and adaptation methods, the eccentric blocks can be flexibly replaced to adjust the vibration force according to the soil quality and construction process requirements, thus broadening the application range of the vibratory compactor and meeting diverse construction scenarios.

[0024] The combined shell 11 has a multi-segment modular structure. Each segment is connected by flange, snap-fit ​​or threaded connection. The upper and lower ends of the inner wall of the combined shell 11 are provided with assembly grooves 12. Rotating seats 13 are installed inside the assembly grooves 12. The vibratory punching mechanism 2 rotates with the combined shell 11 through the rotating seat 13 to form a modular and detachable vibratory punching head structure.

[0025] The hollow shaft 24 is fixedly connected between two rotating seats 13. The water jet pipe 23 passes through the hollow shaft 24, and the top end of the water jet pipe 23 is adapted to connect with the external pipeline via a rotary joint 22 and a threaded pipe connector 21. The threaded pipe connector 21 is adapted to the threaded mounting groove on the top of the rotating seat 13. The rotary joint 22 is rotatably assembled on the top end of the threaded pipe connector 21 to realize the rotational connection between the water jet pipe 23 and the external pipeline, thus avoiding pipe entanglement.

[0026] The submersible motor 28 is installed inside the combined housing 11 via the shock-absorbing support 27.

Different eccentric blocks 26 with different masses and eccentricities can be replaced according to construction needs to adjust the vibration force parameters.

[0027] The assembly of the rotating seat 13 and the assembly slot 12 of the combined housing 11 is a bearing fit or a self-lubricating bushing fit, which ensures the stability and low friction of the vibratory impact mechanism 2 during rotation; the shock-absorbing support 27 adopts a rubber shock-absorbing pad, spring shock absorber or composite shock-absorbing structure to reduce the vibration of the submersible motor 28 during operation and transmit it to the combined housing 11, thereby improving the stability of the equipment; the two pulleys 29 are respectively fixedly connected to the top output end of the submersible motor 28 and sleeved on the outside of the hollow shaft 24.

Adjust the tension with the tension adjustment component.

[0029] Before construction, the submersible motor 28 is started for commissioning, and the rotational stability, vibration output, and water jet pipe 23 of the vibratory compaction mechanism 2 are tested. During construction, the vibratory compactor is hoisted to the work position. If the vibration force needs to be adjusted, the machine is stopped and the eccentric block 26 is replaced. The operation of the submersible motor 28 causes the eccentric block 26 to rotate, generating vibration force, which, in conjunction with the water jet pipe 23, jets water to complete the soil vibratory compaction operation. If a section of the combined outer shell 11 is damaged, the machine is stopped, the corresponding section is disassembled, and repaired or replaced. Daily inspections are conducted on the splicing joints, rotating seat 13, and transmission belt 210. Regular maintenance is performed on the vibratory compaction mechanism 2, including cleaning components, inspecting and replacing worn parts, and testing the performance of the shock absorber support 27 and the submersible motor 28.
