Abstract

The invention belongs to the technical field of auxiliary transportation equipment of underground coal mines, and discloses a narrow mine trackless vehicle power bogie and a walking steering control system. The bogie includes a slew frame, a frame, a swing frame, a swing bridge, a left vertical swing frame, a right vertical swing frame and four working oil cylinders; the left vertical swing frameand the right vertical swing frame are arranged on the two sides of a vehicle, the two ends of each of the left vertical swing frame and the right vertical swing frame are fixedly connected with two wheel fixing frames on one side of the vehicle through a connecting shaft in the vertical direction, the two ends of the swing bridge are provided with first rotating shafts penetrating through the left vertical swing frame and the right vertical swing frame, the swing frame is vertical to the swing bridge, one end of the swing frame is rotationally arranged at the middle portion of the swing bridge, and the other end of the swing frame is hinged to the frame through a second rotating shaft parallel to the swing bridge. A control system includes the bogie, a controller and a hydraulic system, the hydraulic system includes a load-sensitive full hydraulic steering gear, a two-position four-way flameproof solenoid valve, a three-position four-way flameproof solenoid valve and four non-proportionate diverting and collecting valves. The narrow mine trackless vehicle power bogie is small in width and high in flexibility.

Description

technical field [0001] The invention belongs to the technical field of underground auxiliary transportation equipment in coal mines, and in particular relates to a power bogie and a travel steering control system of a narrow trackless vehicle for mining. Background technique [0002] At present, the body width of mine trackless vehicles is generally about 2 meters, which can only be used for transportation in coal mine roadways, and cannot be used in tunnel roadways, resulting in low material transportation efficiency, high labor intensity, and poor safety; in order to achieve rapid and efficient excavation, some Large-scale modern coal mines in China have adopted a full-section rapid and efficient excavation system, which has greatly increased the use of materials such as anchor rods, barbed wire, and drill pipes. These materials can only be transported on both sides of the rapid excavation equipment, and the available width space is 1.2 to 1.4 meters. Existing trackless ve...
