Electric control type diesel pile driver
The invention discloses an electric control type diesel pile driver which comprises a guide rod, a top cross beam and a piston, an electric control fuel system and an electric control unit are arranged on the piston, and a first position sensor and a second position sensor are arranged on the outer side of the piston. The electronic control fuel oil system comprises a fuel oil pump assembly, an oil nozzle assembly and a two-position three-way electromagnetic valve, an oil outlet of the fuel oil pump assembly leads to a pressure oil port P of the two-position three-way electromagnetic valve, a working oil port A of the two-position three-way electromagnetic valve leads to an oil inlet of the oil nozzle assembly, and an oil return port T of the two-position three-way electromagnetic valve is connected to the oil tank; and the electric control unit is electrically connected with the two-position three-way electromagnetic valve. The first position sensor and the uppermost piston ring of the piston body are located on the same plane. The contact points of the second position sensor, the impact pin and the crank arm are located on the same plane. According to the diesel pile driver, the injection control starting time and the injection control pulse width can be adjusted according to working conditions, fuel oil can be injected into the air cylinder at the optimal time, and automatic and accurate control over the oil injection amount and oil injection timing is achieved.
本发明公开了一种电控式柴油打桩机，包括导杆、顶横梁和活塞，活塞上设置有电控燃油系统和电控单元，该活塞的外侧设置有位置传感器一和位置传感器二；电控燃油系统包括燃油泵组件、喷油嘴组件和两位三通电磁阀，燃油泵组件的出油口通向两位三通电磁阀的压力油口P，两位三通电磁阀的工作油口A通向喷油嘴组件的进油口，两位三通电磁阀的回油口T则连向油箱；电控单元与两位三通电磁阀电连接。位置传感器一与活塞活塞体最上一道活塞环处于同一平面上。位置传感器二与撞击销和曲臂的接触点处于同一平面上。该柴油打桩机能根据工况调整喷射控制开始时刻及喷射控制脉宽，燃油能在最优时刻喷入气缸，实现对喷油量及喷油正时自动、精准控制。
