Abstract

The invention discloses a vehicle, a hydraulic system and a cut-off device. The cut-off device comprises a manual cut-off valve and a pipeline II, wherein the manual cut-off valve is arranged on a pipeline I, leading to a hydraulic pump from a hydraulic oil tank, the pipeline II is connected with a main air reservoir and is provided with a valve, and the pipeline II is connected with a pneumatic actuator used for controlling the manual cut-off valve. According to the above cut-off device, control over the hydraulic oil tank pipeline valve can be remotely completed, so that cut-off of the pipeline is achieved, the problem that workers cannot approach a combustion-supporting source to work when a fire occurs is solved, and safety and supportability are improved.

Description

technical field [0001] The invention relates to the technical field of railway rail vehicles, in particular to a cutting device. It also relates to a hydraulic system. A vehicle is also involved. Background technique [0002] Rail vehicles have a mature hydraulic system. When in use, the hydraulic oil tank outputs hydraulic oil for combustion aids. [0003] With the relevant requirements for fire prevention of large-scale road maintenance machinery, the hydraulic system needs to consider additional safety issues such as fire prevention on the basis of satisfying its basic work. After a fire breaks out in the existing railway vehicle-related equipment, the operator cannot approach the hydraulic oil tank, and the combustion-supporting source of the hydraulic oil tank cannot be cut off and controlled immediately, and there is a risk of continuous output or leakage of the combustion-supporting hydraulic oil in the hydraulic oil tank , thereby increasing the danger of the fire...
