Abstract

The invention discloses an underground excavation machine hydraulic control system and a flow distribution system, and relates to the technical field of engineering machines. The technical problem that in the prior art, the function is singular, and consequently the work efficiency is low is solved. The underground excavation machine hydraulic control system comprises a hydraulic power unit and an executing device. The hydraulic power unit is connected with the executing device and can input power hydraulic oil sufficient for driving the executing device to work into the executing device. The executing device at least comprises a material excavating and charging mechanism, a walking mechanism, a groove milling mechanism and a punching mechanism. The walking mechanism is connected with a frame of an underground excavation machine and can drive the underground excavation machine to walk and/or turn. According to the flow distribution system, the flow distribution system is an LUDV flow distribution system and comprises the underground excavation machine hydraulic control system provided by any technical scheme in the embodiment. The flow distribution system is used for enhancing the function of the underground excavation machine hydraulic control system, and the efficiency and the performance of the underground excavation machine hydraulic control system are improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a hydraulic control system of an underground excavator and a flow distribution system provided with the hydraulic control system of the underground excavator. Background technique [0002] During domestic subway construction, the shield machine cannot complete the construction of the platform, and can only be completed with less special equipment. Although some general-purpose equipment with related functions, such as excavators, loaders, etc.) have replaced manual labor to a certain extent , but because of its single function, low energy saving, difficulty in compound action, low efficiency and other defects, it is difficult to meet the working conditions of underground excavation. [0003] The applicant found that: the prior art has at least the following technical problems: [0004] In the existing technology, due to the closed and narrow space of the platform, ...
