The invention discloses a preferential steering double-loop braking quantitative open-type system of a mine vehicle, and relates to the technical field of associated equipment of underground coal mines. The system comprises a gear pump, a safety valve set, a preferential valve, a steering gear, a steering oil cylinder assembly, a prefill valve, a main manifold block, an energy accumulator assembly, a double-line braking valve, a running braker assembly, a control valve, a lifting oil cylinder assembly, an oil return filter, an oil suction filter and a hydraulic oil tank. The preferential steering double-loop braking quantitative open-type system is simple in structure, and the number of applied elements and components is small; and by means of reasonable connection of all connectors of theabove components, preferential steering and double-loop braking of underground trackless auxiliary transportation equipment can be achieved well.
Description
technical field [0001] The invention relates to the technical field of related equipment in underground coal mines, in particular to a dual-circuit brake quantitative opening system with priority steering for mining vehicles. Background technique [0002] Underground coal mine trackless auxiliary transportation equipment has the characteristics of high efficiency, multi-purpose, flexible maneuverability and advanced technology. It has been widely used in some foreign countries with advanced coal mining technology, such as the United States, Australia, the United Kingdom, South Africa and other countries. And has developed rapidly. In the mid-to-late 1990s, in order to change the situation that coal mine auxiliary transportation methods lagged behind the development of mining technology, large mining areas such as Shendong, Yanzhou and Jincheng successively introduced complete sets of trackless rubber wheel transportation equipment, which were used in flat tunnels, vertical s...
