Description

Technical Field

[0001] The present invention relates to a torsion elimination device, in particular to a torsion elimination device applied to a vibrator to prevent the generation of torsion and thus affect the service life of the vibrator, belonging to the technical field of vibrators. Background Art

[0002] A vibrator is a special equipment for the vibratory construction process, which is used to compact the foundation to improve its bearing capacity. The vibrator works by using vibration to squeeze the soil to compact the foundation. Therefore, it is always in a vibrating state. During the vibration process, the water channels and electrical circuits connected from top to bottom will inevitably vibrate at the connection points. The main components of a conventional vibrator are: a vibrating body driven by a motor, a shock absorber connected to the vibrating body, and a lifting head connected to the shock absorber via a guide tube. The waterway and the electric circuit are connected to the shock absorber via a guide tube. Currently, a direct connection method is used. However, in actual applications, it is found that due to the presence of vibration during operation, radial torsion is inevitable. At this time, the torque generated can easily tear the water pipes and wires. For this reason, some companies use flexible materials to replace rigid water pipes and use brush conduction to replace conventional direct wire connection. However, this cannot eliminate the torque generated. Once the adjustment capacity of the flexible material is exceeded, this type of flexible water pipe will still be damaged by torsion. At the same time, due to the relatively harsh working environment of the vibrator, the service life of the flexible material water pipe cannot be guaranteed, and the direct application of the brush method has a serious safety hazard of leakage. Therefore, a solution that can solve the above problems is urgently needed. Summary of the Invention

Preferably, a water storage ring 2.1 with an annular structure is provided on the inner wall of the outer shell 2, and the above-mentioned flushing water diversion channel 4.1 is connected to the water storage ring 2.1; an upper sealing ring 101 and a lower sealing ring 102 are embedded on the inner wall of the outer shell 2, and the upper sealing ring 101 and the lower sealing ring 102 are respectively located above and below the water storage ring 2.1; a flushing water volume adjustment nut 15 is screwed on the bottom of the outer shell 2, and the outer wall of the flushing water volume adjustment nut 15 is connected to the inner wall of the outer shell 2 by threaded fitting, the inner wall of the flushing water volume adjustment nut 15 is in sliding contact with the outer wall of the inner shell 1, and the top of the flushing water volume adjustment nut 15 abuts against the lower sealing ring 102;

[0025] The end cover 8 is fixedly connected to the outer shell 2, and the upper end of the central water pipe 5 passes through the end cover 8 and is connected to the upper water pipe joint 9. The central water pipe 5 is sleeved with a slip ring 10, which is located in the inner shell 1. The slip ring 10 includes a rotor 10.1 and a stator 10.2 that is rotatably and slidingly sleeved on the rotor 10.1. The rotor 10.1 is connected to the mounting plate 4 via a connecting seat 11 (and the rotor 10.1 does not contact the outer wall of the central water pipe 5).
