Self-adaptive floating breathing device and breathing oil tank with same

Abstract

The invention discloses a self-adaptive floating breathing device and a breathing oil tank with the same. The breathing device comprises a slidable floating breathing block arranged in the oil tank, the floating breathing block communicates with the outside through a breathing hose arranged on the floating breathing block, and when the oil tank is inclined, the floating breathing block slides to ahigh point to be prevented from being in contact with oil liquid. According to the breathing device, the gradient change can be automatically induced, the breathing position can be automatically changed according to change of the inclination angle of the oil tank, so that the breathing position is always kept at the highest position of the oil tank. Through the action of the breathing system, theinclination angle of the oil tank is automatically induced, a power traction block slides to the lower side, at the same time, the floating breathing block is dragged to slide to the higher side along a guide rod, so that the position of a breathing opening is always at the highest position to be prevented from being submerged by the oil liquid; and the floating breathing block communicates withthe atmosphere through the breathing hose and an air filter, so that the normal breathing function of the oil tank can be met even when the inclination angle of the oil tank is large or the angle change is large.

Description

technical field [0001] The invention belongs to the technical field of coal mine machinery, and in particular relates to an adaptive floating breathing device and a breathing oil tank with the breathing device. Background technique [0002] The roadway excavation face machine excavation process usually uses a cantilever type roadheader, and the climbing ability of the roadheader is generally below 18°. When the inclination angle of the coal seam is large or the coal seam fluctuates violently due to the influence of the geological structure, due to the limitation of the climbing ability of the roadheader itself, it is impossible to continue to use the machine-dug construction roadway, which restricts the mechanized and efficient production of the coal roadway to a certain extent. This is also a problem that is difficult to solve in the process of coal production in our country. [0003] At present, many domestic scientific research institutes and mining companies have carrie...
