Description

Technical Field

[0001] This invention relates to an ultra-high power vibratory impactor, and more particularly to a slender ultra-high power vibratory impactor with extremely high reliability based on a permanent magnet motor, belonging to the field of vibratory impactor technology. Background Technology

[0002] Currently, to improve the impact force of vibratory compactors to adapt to complex geological environments, permanent magnet motors are being used as replacements for traditional submersible motors. Permanent magnet motors, due to the incorporation of rare earth elements in their rotors, eliminate eddy currents compared to traditional motors (reducing heat loss and energy consumption, resulting in significant energy savings). They also have a stronger magnetic field (generating greater torque with the same current, helping to reduce coil windings and motor size) and faster response (ensuring real-time and precise control, leading to smoother vibratory compactor operation). In summary, the introduction of permanent magnet motors gives vibratory compactors better power input, energy efficiency, longer service life, and faster response speed. Furthermore, to match ultra-high power applications, multiple permanent magnet motors are cascaded to achieve ultra-high power operation while maintaining the compactor's slender shape.

[0003] The conventional method for introducing cables into this type of permanent magnet motor vibratory impactor is through direct connection within a junction box. However, because water and air lines require simple wiring and conduit installation within the junction box, the cable connections cannot be completely sealed during operation. Water ingress can lead to short circuits and other accidents. The operating environment of the vibratory impactor inevitably allows water droplets and moisture to overflow from the water pipe connections, directly contacting the cable joints or condensing there. This water can cause short circuits or potentially drip into the motor through gaps between the copper cable and insulation, further damaging the motor and severely impacting the vibratory impactor's lifespan. Therefore, a highly reliable, slender, ultra-high-power permanent magnet vibratory impactor with excellent sealing performance is needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a highly reliable, slender, ultra-high power permanent magnet vibratory impactor with excellent sealing and waterproof performance.

[0005] The objective of this invention is achieved as follows: A highly reliable, slender, ultra-high-power permanent magnet vibratory impactor is disclosed. The drive motor of the vibratory impactor is composed of multiple cascaded permanent magnet motors. The uppermost drive motor is connected to the hoisting part via a sealing structure. The sealing structure includes a connecting pipe. A partition plate is arranged along the axial direction inside the connecting pipe, and the partition plate divides the cavity of the connecting pipe into an electrical chamber and a pipeline chamber. Sealing plates are respectively arranged at both ends of the partition plate. The partition plate, the sealing plates, and the inner wall of the connecting pipe form a sealed electrical chamber. A wire hole is provided on the sealing plate, and a packing is embedded in the wire hole.

[0006] Preferably, the partition plate is mounted on one side of the electrical cavity with a terminal assembly.

[0007] Preferably, an operating hole is provided on at least one side of the connecting pipe wall, and the operating hole is connected to the electrical chamber. The operating hole is also covered by a cover plate.

The operating plate is screwed onto the partition plate by fastening bolts, and the terminal assembly is mounted on the operating plate.

[0010] A highly reliable, slender, ultra-high-power permanent magnet vibratory impactor is disclosed. The drive motor of the vibratory impactor is composed of multiple cascaded permanent magnet motors. The uppermost drive motor is connected to the hoisting part via a sealing structure. The sealing structure includes a connecting pipe. The upper and lower parts of the inner wall of the connecting pipe are respectively provided with axially arranged partition strips. Two partition plates are provided, which are located on both sides of the partition strips. The upper and lower ends of each partition plate are respectively connected to the upper and lower partition strips by connecting bolts.

Packing is embedded in the wire hole on the sealing plate.

[0011] Preferably, operating holes are provided on both sides of the connecting pipe, and the operating holes are connected to the pipe cavity.

[0013] Preferably, both ends of the connecting pipe are fitted with mounting flanges.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention replaces the conventional external junction box with a connecting pipe, and within the connecting pipe, a partition plate separates and forms a relatively completely sealed electrical chamber, thereby ensuring the complete reliability of the electrical connection.

[0023] See Figures 1-3 This invention relates to a highly reliable, slender, ultra-high-power permanent magnet vibratory shock absorber. The drive motor of the shock absorber is composed of multiple cascaded permanent magnet motors. The uppermost drive motor is connected to the hoisting part via a sealing structure. The sealing structure includes a connecting pipe 1. A partition plate 2 is arranged along the axial direction inside the connecting pipe 1, and the partition plate 2 divides the cavity of the connecting pipe 1 into an electrical chamber and a pipeline chamber. Sealing plates 3 are respectively arranged at both ends of the partition plate 2. The partition plate 2, the sealing plate 3, and the inner wall of the connecting pipe 1 enclose a sealed electrical chamber. The sealing plate 3 is provided with a wire hole, and a packing 4 is embedded in the wire hole, so that the electrical chamber can still be sealed even when cables, temperature sensors, etc. are inserted.

[0024] The partition plate 2 is equipped with a terminal assembly 6 at one end of the electrical cavity, which is used to quickly connect the wiring cable after it is inserted from the end plates 3 at both ends to the two ends of the terminal assembly 6.

[0025] Meanwhile, to facilitate operation of the cables within the electrical chamber, an operating hole 1.1 is provided on the wall of the connecting pipe 1, and the operating hole 1.1 communicates with the electrical chamber. This allows the operator to easily connect the cable inserted into the electrical chamber to the terminal assembly 6 through the operating hole 1.1. After wiring is completed, the cover plate 5 is sealed by bolts onto the operating hole 1.1. To further improve the sealing effect, a continuous sealing flange 1.2 protrudes outward around the operating hole 1.1, and a continuous sealing groove 5.1 is formed inward around the cover plate 5. This allows the sealing flange 1.2 to be inserted into the sealing groove 5.1 to achieve a seal, thereby improving the sealing effect.

[0026] Finally, in order to facilitate the connection, management and maintenance of the pipeline in the pipeline cavity, another operating hole 1.1 is opened on the other side of the pipe wall of the connecting pipe 1. The operating hole 1.1 is connected to the pipeline cavity and is also covered by a cover plate 5.

[0027] In use, the cable is inserted into the electrical chamber through the packing 4 from the two sealing plates 3 and then electrically connected through the terminal assembly 6. At this time, the connection operation is carried out through the operating hole 1.1 connected to the electrical chamber. Then, the cover plate 5 is screwed onto the operating hole 1.1 to achieve a complete seal of the electrical chamber. On the other side, the pipeline chamber is used to connect the water or gas circuit. It can also be operated through the operating hole 1.1 connected to the pipeline chamber. After the operation is completed, the corresponding cover plate 5 is closed. Example 2:

[0028] See Figures 4-5This invention relates to a highly reliable, slender, ultra-high-power permanent magnet vibratory shock absorber. The drive motor of the shock absorber is composed of multiple cascaded permanent magnet motors. The uppermost drive motor is connected to the hoisting part via a sealing structure. The sealing structure includes a connecting pipe 1. A partition plate 2 is arranged along the axial direction inside the connecting pipe 1, and the partition plate 2 divides the cavity of the connecting pipe 1 into an electrical chamber and a pipeline chamber. Sealing plates 3 are respectively arranged at both ends of the partition plate 2. The partition plate 2, the sealing plate 3, and the inner wall of the connecting pipe 1 enclose a sealed electrical chamber. The sealing plate 3 is provided with a wire hole, and a packing 4 is embedded in the wire hole, so that the electrical chamber can still be sealed even when cables, temperature sensors, etc. are inserted.

[0029] The partition plate 2 is equipped with a terminal assembly 6 at one end of the electrical cavity, which is used to quickly connect the wiring cable after it is inserted from the end plates 3 at both ends to the two ends of the terminal assembly 6.

[0030] Meanwhile, to facilitate operation of the cables within the electrical chamber, an operating hole 1.1 is provided on the wall of the connecting pipe 1, and the operating hole 1.1 communicates with the electrical chamber. This allows the operator to easily connect the cable inserted into the electrical chamber to the terminal assembly 6 through the operating hole 1.1. After wiring is completed, the cover plate 5 is sealed by bolts onto the operating hole 1.1. To further improve the sealing effect, a continuous sealing flange 1.2 protrudes outward around the operating hole 1.1, and a continuous sealing groove 5.1 is formed inward around the cover plate 5. This allows the sealing flange 1.2 to be inserted into the sealing groove 5.1 to achieve a seal, thereby improving the sealing effect.

[0031] Finally, to facilitate the connection, management, and maintenance of the pipelines within the pipeline chamber, the difference between Embodiment 2 and Embodiment 1 is that Embodiment 2 does not involve opening a hole in the wall of the connecting pipe 1, thereby reducing the connection between the connecting pipe 1 and the outer wall and improving sealing performance. In this case, an inner operating hole 2.1 is opened on the partition plate 2, and a sealing boss 8.1 is raised on the operating plate 8. The sealing boss 8.1 is embedded in the inner operating hole 2.1, and the outer wall of the sealing boss 8.1 is in close contact with the inner wall of the inner operating hole 2.1. An annular sealing groove 8.2 is provided on the outer wall of the sealing boss 8.1, and a sealing ring 9 is embedded in the sealing groove 8.2. The operating plate 8 is screwed onto the partition plate 2 around its perimeter using fastening bolts, and the terminal assembly 6 is installed on the operating plate 8.

[0032] When it is necessary to operate the pipeline in the pipeline chamber, first remove the cover plate 5, disconnect the upper and lower connecting cables on the terminal assembly 6, then remove the operating plate 8, and operate the pipeline in the pipeline chamber through the inner operating hole 2.1 on the partition plate 2. Example 3:

[0033] See Figures 6-7 This invention relates to a highly reliable, slender, ultra-high-power permanent magnet vibratory impactor. The drive motor of the vibratory impactor is composed of multiple cascaded permanent magnet motors. The uppermost drive motor is connected to the hoisting part via a sealing structure. The sealing structure includes a connecting pipe 1. The upper and lower parts of the inner wall of the connecting pipe 1 are respectively provided with axially arranged partition strips 1.3. Two partition plates 2 are provided, located on both sides of the partition strips 1.3. The upper and lower ends of each partition plate 2 are respectively connected to the upper and lower partition strips 1.3 by connecting bolts, thereby forming an electrical chamber between the two partition plates 2 and the upper and lower partition strips 1.3. Both ends of the two partition plates 2 are provided with sealing plates 3. Packing 4 is embedded in the wire hole on the sealing plate 3 to achieve sealing of the electrical chamber. Two pipeline chambers are formed between the two partition plates 2 and the inner wall of the connecting pipe 1, which are used to connect and install water pipes and gas pipes.

[0034] Meanwhile, to facilitate operation of the cables in the electrical chamber and the pipes in the pipeline chamber, operating holes 1.1 are provided on both sides of the connecting pipe 1, and the operating holes 1.1 are connected to the pipeline chamber. This allows the operator to easily operate inside the cavity of the connecting pipe 1 through the operating holes 1.1. The cover plate 5 is sealed to the operating holes 1.1 by bolts. A continuous sealing flange 1.2 is provided around the operating holes 1.1. A continuous sealing groove 5.1 is formed around the cover plate 5, so that the sealing flange 1.2 is inserted into the sealing groove 5.1 to achieve a seal and improve the sealing effect.

[0035] Meanwhile, an inner operating hole 2.1 is provided on the partition plate 2, and the sealing gasket 10 is attached to the inner operating hole 2.1. The sealing gasket 10 is located between the partition plate 2 and the partition strip 1.3. It is fastened and sealed by connecting bolts. When it is necessary to operate the cable in the electrical cavity, first remove the cover plate 5 on one side of the connecting pipe 1, then unscrew the connecting bolt on the partition plate 2 in the corresponding pipe cavity and remove the partition plate 2 and the sealing gasket 10. Then the cable in the electrical cavity can be operated. The operation method on both sides is similar. The terminal assembly 6 is fixedly installed on any partition strip 1.3. After the cable operation is completed, the partition plate 2 and the sealing gasket 10 are fixedly installed back on the upper and lower partition strips 1.3.

[0036] Meanwhile, in the above three embodiments, both ends of the connecting pipe 1 are fitted with mounting flanges 7, which facilitates the installation of the present invention on the vibratory beater.

[0037] Additionally, it should be noted that the above-described specific implementation is merely an optimized solution of this patent, and any modifications or improvements made by those skilled in the art based on the above concept are within the scope of protection of this patent.
