Problems solved by technology

[0006] To sum up, the traditional support truck has the disadvantages of large turning radius, difficult steering, or poor yaw stability. It is urgent to develop a support truck that can solve the above two problems at the same time and is more suitable for the road conditions of coal mine underground roads.

Abstract

The invention relates to the technical field of underground coal mine railless auxiliary transportation, in particular to an integrated bracket carrying vehicle with double steering gears. The integrated bracket carrying vehicle with the double steering gears comprises a U-shaped vehicle frame, a front vehicle frame connected to the front end of the U-shaped vehicle frame through pins, hydraulic suspension, a steering system with the double steering gears, a lifting device arranged on the U-shaped vehicle frame, a diesel power system arranged in the front vehicle frame, and a cab mounted on the front vehicle frame; one part of the steering system with the double steering gears is arranged in the cab, and the other part of the steering system with the double steering gears is arranged in the U-shaped vehicle frame; and the U-shaped vehicle frame and the steering system with the double steering gears are connected to the hydraulic suspension. According to the integrated bracket carryingvehicle with the double steering gears, a front steering wheel set and a rear steering wheel set can be controlled by the main steering gear and the auxiliary steering gear correspondingly, the driving controllability is greatly improved, the contradiction between high-speed driving controllability and low-speed turning flexibility is avoided, the problem that the vehicle has the difficulty in adjusting the attitude when reversing to load a hydraulic support is solved, and steering flexibility and high-speed driving stability are improved.

Description

technical field [0001] The invention relates to the technical field of underground trackless auxiliary transportation in coal mines, in particular to a double-steering integral support carrier. Background technique [0002] The support truck is a special vehicle for transporting hydraulic supports underground in coal mines. It usually has an articulated structure with front and rear frames. The front frame carries the power assembly and cab, and the rear frame is a U-shaped frame structure for carrying hydraulic supports. When loading the vehicle, make the U-shaped frame face the hydraulic support, and then reverse the vehicle until the U-shaped frame fully or partially accommodates the hydraulic support, and then mount the hydraulic support with the chain on the lifting device. With the heavy hydraulic support, the carrying capacity of the support truck has grown from 30 tons to 100 tons, the inner turning radius has also developed from 2.5 meters to 4.8 meters, and the out...
