Underground coal mine short-distance multi-purpose special hoisting vehicle device

Abstract

The invention discloses an underground coal mine short-distance multi-purpose special hoisting vehicle device including a mining vehicle chassis, an equipment placing frame, a lifting arm, a rotatingshaft, support leg hydraulic cylinders, a lifting hydraulic cylinder, two sets of wheel pairs, two bump heads, a complete chassis, channel steel, a transition frame, a steel plate, a connection plateand a base. The equipment placing frame is provided with a hydraulic station and a magnetic starter, the hydraulic station is connected with the magnetic starter through a cable, a travel motor and apipe of the hydraulic station are connected and installed, the four corners of the transition frame are equipped with the support leg hydraulic cylinders, the two ends of the lifting hydraulic cylinder are connected to the lifting arm and the rotating shaft, the lifting hydraulic cylinder supports the lifting arm, the magnetic starter converts electrical energy into hydraulic energy through the hydraulic station, the hydraulic energy enters all functional electromagnetic reversing valves through high-pressure oil pipes, the electromagnetic reversing valves are operated to control the hydrauliccylinder and the motor, and therefore the functions of travelling, lifting and stable supporting are realized; and by rotating the lifting arm, material transfer within a large angle range can be realized.

Problems solved by technology

[0002] With the continuous innovation and rapid development of science and technology, the production environment and appearance of coal mines have been continuously improved, the degree of mechanization, informationization, and intelligence has been gradually improved, and the working environment and production conditions of laborers have been greatly improved. , the working mode of laborers is limited by environmental conditions, it is difficult to change fundamentally, coal miners have to engage in heavy physical labor for a long time

[0003] At present, the main form of transportation in coal mines is still rail transportation. In the process of material transfer, material loading and unloading, and equipment installation and withdrawal, the backward methods of manual handling and hand-carrying are still generally used. For heavier materials, they are carried by rooting and hanging Hanging points, using wire rope buckles, chain hoists, etc. for lifting operations, not only the material loading and unloading efficiency is low, the construction period is long, but also the labor intensity of the workers is high, and the safety risk is high

[0004] Under coal mines, materials are generally stored centrally in the transfer yard in the main road and the temporary storage yard in the mining area. Due to the fixed location of the transfer yard in the main road, pneumatic hoists or driving can be installed for auxiliary loading and unloading, while the temporary storage yard in the mining area is due to Due to the limitation of roadway conditions and the installation and withdrawal of the mining head, the location and position will change frequently, and the installation and removal of the pneumatic hoist will be labor-intensive and time-consuming. At this time, a special equipment that can load and unload materials in a short distance in the limited space of the mining area is needed. car device
