Problems solved by technology

But it will cause some damage to the pile body
In addition, although the impact frequency of existing hydraulic rock drills is relatively high, due to the small mass and small impact force of the impact hammer in the body, it cannot meet the needs of drilling large-diameter rock holes.
The main problem is that the impact frequency is low, or the impact force is small

Abstract

The invention relates to a hydraulic excitation high-frequency linear impact device, and belongs to the field of machines. The hydraulic excitation high-frequency linear impact device comprises a hydraulic cylinder, an impact hammer, an impact seat and an impacted body; the hydraulic excitation high-frequency linear impact device is characterized in that the hydraulic cylinder is an unequal-diameter hydraulic cylinder with double output rods; a piston rod of the hydraulic cylinder is connected with the impact hammer, a small-diameter piston rod cavity oil cavity of the hydraulic cylinder is connected to a control oil pipe, a large-diameter piston rod cavity oil cavity of the hydraulic cylinder is connected with a high pressure oil pipe, the high pressure oil pipe is connected with an inputoil pipe, the control oil pipe is connected with the impact valve, and the impact valve is connected to a control motor. The hydraulic excitation high-frequency linear impact device is small in overall quality and high in impact frequency, the impact hammer has high accelerated speed, and high-frequency large impact force can be generated. The work efficiency can be improved, and the effect of rapid pile sinking can be achieved.

Description

technical field [0001] The present invention relates to machines that work in impact mode, such as large-diameter hydraulic rock drills, piling machines and machines that use vibration to work. Background technique [0002] Existing impact machinery such as the impact device of the hydraulic pile driver generally all is to raise the impact hammer to a certain height by means of hydraulic pressure, and then freely falls to strike the pile to make the pile body sink. In order to obtain greater striking force, it is necessary to increase the mass of the impact hammer. The impact frequency of the impact device is very low, generally below 50 times / min, the power consumption is large, and the efficiency is low. This method is to first allow the impact hammer to have a certain potential energy, and then fall freely to strike, which can produce a greater impact on the pile body. But it will cause some damage to the pile body. In addition, although the impact frequency of existin...
