Embodiment Construction

[0010] The hydraulic vibrator disclosed in the present invention is composed of two parts: a vibrator and a power supply system.

[0011] Such as figure 1 As shown, the vibrator consists of a housing with a tapered head 1, a hydraulic motor built in the housing 2, a coupling 3 connected to the output shaft of the motor, a polarization rotor 4 connected to the other end of the coupling, and a polarization rotor 4 A bearing 5 connected to the rotor, a cone-shaped vibrating head 6 connected to the bearing 5, and a water channel 7 wrapped outside the housing 1 are combined.

[0012] The hydraulic motor 2 inside the vibrator is connected to the power supply system through an oil pipe. The power supply system outputs different flows according to different geological formations, and drives the hydraulic motor to drive the polarization rotor 4 and the vibrating head 6 to vibrate at different vibration frequencies to produce different vibrating effects to meet the needs of different formati...

Abstract

The invention discloses a hydraulic vibroflotation device, which is composed of a vibroflotation device and a power supply system. The vibroflotation device is composed of a conical casing in the front, a hydraulic motor inside the casing, a shaft coupling connected with a motor output shaft, a polarizing rotor linked to the other end of the shaft coupling, a bearing connected with the polarizing rotor, a conical vibroflotation small end linked to the bearing, and a water channel embedded inside the casing; the hydraulic motor inside the vibroflotation device is connected with the power supply system through oil pipes. The power supply system comprises a primary working unit and a lubricating and cooling unit. The power supply system can follow different formation demands to adjust output flow rate, drive the hydraulic motor and regulate the output revolution speed to change vibroflotation force, so as to adapt to demands for different formations. Besides, the power supply system also comprises the lubricating and cooling unit to guarantee normal operation of the system; moreover, the power supply system is also added with an accumulator to protect the overall oil circuit system from being damaged via too much vibration.

Description

Technical field [0001] The invention relates to a vibrator applied in the construction process of a vibroflotation method, in particular to a hydraulic vibrator which can adjust the vibration frequency according to different geological layers of the construction site. Background technique [0002] Vibroflotation is to use the vibrator’s strong vibration and pressure water to pour deep into the soil to densify the loose sand foundation, or to fill the soft soil layer with non-cohesive clay particles such as gravel to form a strength greater than the surrounding soil It is a reinforcement technology that makes the column pile and the original foundation soil form a composite foundation to improve the strength of the foundation. This method is mainly used in foundation treatment projects of large-scale construction projects such as thermal power stations and ports. [0003] Vibroflotation is the main construction equipment in vibro-impact construction. At present, the most widely us...
