Hydraulic track lifting and lining device
The invention discloses a hydraulic track lifting and lining device. The device comprises a base, an oil cylinder and an oil tank, the oil cylinder comprises an oil cylinder sleeve, a piston and a small piston, and further includes a plunger pump, the plunger pump comprises a plunger base and a pump body installed in the plunger base, the oil tank is installed at one end of the plunger base, a driving motor is installed at the other end of the plunger base, the oil cylinder is installed on the plunger base, the plunger pump is in transmission connection with the driving motor, the oil tank, the plunger pump and the small piston are connected through oil ways, the oil tank and the piston are connected through an oil suction channel, an oil suction one-way valve is arranged on the oil suction channel, and all the oil ways are arranged in the plunger base. After the driving motor is started, the plunger pump is driven to rotate, oil in the oil tank is fed into the small piston through theoil way, the small piston can drive the piston to synchronously stretch out, negative pressure is formed in an inner cavity of the piston in the stretching process of the piston, the oil is sucked into the piston through the oil suction channel, and pressure change in the piston is compensated.
本发明公开了一种液压起拔道器，包括基座、油缸和油箱，所述油缸包括油缸套、活塞和小活塞，还包括有一柱塞泵，所述柱塞泵包括柱塞座和安装在柱塞座内的泵体，所述油箱安装在柱塞座的一端、柱塞座的另一端安装有驱动电机，所述油缸安装在柱塞座上，所述柱筛泵与驱动电机传动连接，所述油箱、柱塞泵与小活塞间油路连接，所述油箱与活塞之间通过一吸油通道连接，所述吸油通道上设置有吸油单向阀，所有油路均设于柱塞座内。驱动电机启动后，带动柱塞泵转动，从而将油箱中的油通过油路送入到小活塞中，小活塞会带动活塞同步伸出，在活塞伸出的过程中，活塞内腔室形成负压，从而通过吸油通道将油吸入活塞中，对活塞内压力变化形成补偿。
