Problems solved by technology
[0004] In the prior art, the steering mechanism of the mining dump truck has many connection links, which causes the problems of reduced operating efficiency and reduced reliability. In addition, since the steering gear is fixedly arranged under the floor of the cab, it is difficult to install and disassemble it. The bolts must be plugged from the upper part of the walking platform of the whole vehicle, and at the same time tightened and fixed at the bottom of the walking platform, which is inconvenient for loading, unloading and maintenance

The invention provides a steering control mechanism of a mining dump truck and the mining dump truck. The steering control mechanism of the mining dump truck comprises a steering gear and a partition plate, wherein the steering gear is connected with the first end of a steering column tube, the steering gear and the steering column tube share the same axis, the second end of the steering column tube is connected with a steering wheel, a fixing frame is arranged between the first end and the second end of the steering column tube, the fixing frame is used for being connected with a cab framework of the mining dump truck, the partition plate is connected with the steering gear and the steering column tube, and the partition plate is used for being connected with the cab framework to form a cabin to seal the steering gear. The steering control mechanism of the mining dump truck can improve the control efficiency and the reliability, and be convenient to disassemble, assemble and maintain.
Description
technical field [0001] The invention relates to the technology of mine vehicle control equipment, in particular to a steering mechanism of a mine dump truck and the mine dump truck. Background technique [0002] At present, heavy-duty mining dump trucks all adopt hydraulic power steering and are equipped with a steering gear. The steering gear is connected to the steering cylinder through a hydraulic oil pipe, and the steering cylinder is hydraulically driven to perform wheel steering. The steering gear must be isolated from the driver during installation, and the steering gear can be disassembled from the cab without dismantling the oil pipe as much as possible during maintenance to prevent oil leakage. [0003] Please refer to figure 1 , the steering mechanism of the existing mining dump truck includes a steering wheel 203, the steering wheel 203 is connected to the steering column tube 202, and the steering column tube 202 is connected to the top of the connecting rod 10...
