Design of Power Head of Hydraulic Pile Driver
The usual hydraulic power head can complete the main operation and the feed operation, and there is a power component that automatically repeats the workpiece.Hydraulic pile driverA very simple speed-adjusting transmission mechanism in various ways. The basic concept is that the motor pulls a gear speed-adjusting mechanism, which can complete the functions of boring, milling, drilling, etc., and some have guide rails that can be used in small areas. Straight line movement. The core technology of the hydraulic power head selected by the hydraulic pile driver is the full hydraulic power head. The power is completed by using a three-phase asynchronous motor to drive the axial plunger hydraulic pump. The high-pressure oil output by the hydraulic pump flows to each operating device according to the control valve to drive each Operating device operation.
The advantages of full hydraulic power head compared with traditional power head:
1. With large output torque, it can effectively drill into pebble layers, strongly weathered rock layers and harder geological layers, which greatly expands the construction area of the hydraulic pile driver.
2. The power head can be started with load. In the process of drilling and piling, if the power head stops due to accidental conditions, after the main pump motor is restarted, it can be started in the original area, reducing the control strength of the operator, which is conducive to control, but other power heads cannot do it. .
3. The variability of the power head speed. The change of the formation resistance is fed back to the hydraulic motor of the power head according to the system pressure, and the hydraulic motor control mechanism adjusts the displacement according to the pressure, so that the suitable rotation speed is realized to continue drilling, and the formation adaptability is strong.
4. The weight of the power head is much lighter than the three-ring power head reducer, which reduces the shaking of the entire equipment when the hydraulic pile driver moves with the drill rod. The effectiveness enhances the reliability of the entire equipment and ensures safe construction.
5. The power head and the whole equipment designed by the hydraulic pile driver adopt hydraulic transmission, which effectively reduces the mechanical vibration of the pile driver structure and can extend the service life of the entire equipment structure.
