Abstract

The invention discloses an oil feeding device comprising a hydraulic cylinder. A cylinder body piston separates a gas chamber from a liquid chamber. The gas chamber is provided with a gas inlet which provides kinetic energy for the cylinder body piston. The liquid chamber is provided with an oil outlet through which oil is fed into a vehicle hydraulic system. An integrated quick connector is arranged between the oil outlet and the hydraulic system. The liquid chamber is further provided with an oil injection hole used to feed oil into the vehicle hydraulic system, and the oil injection hole is connected with an oil storage tank. A cut-off valve is arranged between the oil injection hole and the oil storage tank, and a cut-off valve is arranged between the oil outlet and the integrated quick connector. The oil feeding device further comprises an oil return tank which is connected with the hydraulic system to realize oil return and gas discharge. A safety valve used for pressure relief is arranged between the gas inlet and a gas source. A pilot-operated one-way speed control valve used for controlling the oil feeding speed is arranged between the safety valve and the gas inlet. By adopting the oil feeding device, air can be prevented from entering the hydraulic system to affect the execution thereof, and the purpose of efficient and safe oil feeding is achieved.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to an oil replenishing device. Background technique [0002] With the rapid development of my country's track construction, the market demand for various types of oil replenishment devices is increasing. [0003] At present, the brake actuators and rescue support components of most maglev vehicles adopt the method of gas-hydraulic pressurization. Due to the complicated connection of hydraulic pipelines, there are many leakage points; therefore, any leakage of pipelines or internal pressure of hydraulic components Leakage will directly affect the execution force of hydraulic actuators and threaten driving safety. [0004] In the prior art, manual oil replenishment is usually used; since the circuits of the hydraulic components of the magnetic levitation vehicle are relatively independent, when leakage occurs in multiple circuits, oil must be manually replenished one b...
