Underground grease car for coal mine

Abstract

The invention particularly relates to an underground grease car for a coal mine. The underground grease car for the coal mine solves the problem that time and labor are wasted, cost is high, and grease extraction efficiency is low when the existing grease is stored by digging caves. Grease containers are arranged on a flat car side by side, grease level displaying meters and grease filling pipes are arranged on the lateral walls of the grease containers, a filtering screen is arranged at the upper ends of the grease filling pipes, and grease outlets are arranged at the bottoms of the lateral walls of the grease containers. A grease pot storing tank and a manual grease pumping unit storing tank are arranged in front of and at the rear end of the grease containers, a pneumatic grease pumping unit storing tank is arranged at the upper end of the grease pot storing tank, and a pneumatic grease pumping unit is arranged in the pneumatic grease pumping unit storing tank. The pneumatic grease pumping unit comprises a frame, wherein a gear pump and a pneumatic drilling machine which are vertically distributed are fixed on the frame, the pneumatic drilling machine is connected with the gear pump through a drilling chuck, and a grease sucking pipe communicated with a grease barrel and a grease discharging pipe communicated with the grease filling pipes of the grease containers are arranged on the gear pump. By means of the underground grease car for the coal mine, the starting-up efficiency is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to a grease storage device, in particular to an underground grease truck in a coal mine. Background technique [0002] With the continuous improvement of the degree of mining mechanization, the mining equipment used in the underground mining face is becoming more and more precise and durable, and the lubrication of mechanical transmission and hydraulic transmission are also becoming more and more popular. Supply custodial work is also increasingly important. [0003] At present, coal mines generally dig caves near the underground working face to store grease, that is, as a temporary grease storage for the underground working face. Since opening a grease depot requires deliberately drilling a cave near the working face, it takes a lot of manpower and time, and the corresponding cost is relatively large. Moreover, the distance between the grease depot and the working face is relatively long, and it is also more troublesome for work...
