A roadway transport vehicle

Abstract

The invention relates to a roadway material transport vehicle. The roadway material transport vehicle includes a loading platform on which a gravity sensor is arranged; a crawler chassis on which the loading platform is arranged; a hydraulic motor including a first hydraulic The motor and the second hydraulic motor, the reduction box, including the first reduction box and the second reduction box, the first reduction box is connected with the first hydraulic motor, the second reduction box is connected with the second hydraulic motor; the driving wheel, the left wheel is connected with the first The reduction box is connected, and the right wheel is connected with the second reduction box; the one-way control valve is respectively connected with the first reduction box and the second reduction box through the first pipeline; the multi-way reversing valve is respectively connected with the second reduction box through the second pipeline. A hydraulic motor is connected to the second hydraulic motor to control the first hydraulic motor and the second hydraulic motor, and a solenoid valve is installed on the second pipeline; the speed of the material transport vehicle can be adjusted according to the actual road conditions, effectively improving the transportation efficiency of the material transport vehicle , Improve the stability and safety of material transportation.

Description

technical field [0001] The invention relates to the field of coal mining, in particular to a roadway material transport vehicle. Background technique [0002] In the existing coal mine excavation face, the advanced bolt-mining integrated machine is used for operation. The site support material storage point is between 100-200 meters away from the working face. The road at this distance is a newly excavated road with no bottom pavement, and it is difficult for people to walk. [0003] The newly excavated unpaved road surface is usually bumpy. In addition to the installation of the belt conveyor, other equipment and material racks are installed in the roadway, which occupies part of the roadway space and the remaining roadway width is limited. [0004] At present, there are two main ways of transporting materials on the working face: manual loading of materials to the working face, this scheme employs a large number of people and the labor intensity of the staff is extremely ...

AI Technical Summary

Problems solved by technology

[0004] There are two main methods of transporting materials to the working face: Manually carrying materials to the working face. This scheme employs a large number of people and the labor intensity of the staff is extremely high.

According to the current coal mine anti-scour management regulations, the number of people entering the key anti-scour area of ​​the excavation face cannot exceed 9, and this scheme cannot meet the requirements of the current anti-scour management regulations.

Diesel-powered explosion-proof vehicles can also be used to transport materials. First, due to poor road conditions and insufficient space, it is difficult for explosion-proof vehicles to operate and cannot reach the shortest distance from the working face; There is no safe distance for vehicles to walk, and accidents are prone to occur; third, the use of diesel power for explosion-proof vehicles will cause great environmental and noise pollution on the site
