Problems solved by technology

The traveling box is a key component of the coal shearer. Since the traveling box is driven by an open gearbox, the gear chamber is directly connected to the underground coal mining face. Extremely harsh, complex and changeable stress conditions, heavy maintenance work during use, and gears often fail due to severe wear
In addition, the traction power of the walking box is as high as 200kW, the number of transmission gears is large, the size is large, and the heat dissipation is high. It is difficult to meet the needs of lubrication and cooling by using the traditional oil dripping device
[0003] Therefore, there is a lack of a lubricating and cooling device and method for the walking box of a coal mining machine nowadays, which solves the problem of lubrication and cooling of the internal gears of the extra-high power walking box

Abstract

The invention discloses a lubricating and cooling device and method for a walking box of a coal mining machine. The device comprises an oil drip lubricating mechanism arranged on the top of the walking box of the coal mining machine and a cooling mechanism arranged on the walking box of the coal mining machine, wherein the oil drip lubricating mechanism comprises an oil drip box body, a drip tubeand an oil drip adjusting part; and the oil drip adjusting part comprises a sealing cover, an adjusting screw rod, a circular protection cylinder and a drip tube. The method comprises the following steps of 1, mounting the oil drip lubricating mechanism and the cooling mechanism; 2, adjusting the oil drip lubricating mechanism and the cooling mechanism; and 3, lubricating and cooling the walking box of the coal mining machine. According to the lubricating and cooling device and method for the walking box of the coal mining machine, lubricating oil and cooling water are mixed to lubricate and cool a transmission gear in the walking box, so that the aims of lubricating and cooling of a walking box inner gear of the super-high-power walking box are achieved.

Description

technical field [0001] The invention belongs to the technical field of lubricating and cooling a traveling box of a coal mining machine, and in particular relates to a lubricating and cooling device and method for a traveling box of a coal mining machine. Background technique [0002] Coal is the main energy source of our country and has supported the development of our country's economy for many years. At this stage, our country produces about 3.5 billion tons of raw coal every year. Shearer is the key equipment of coal production, its efficient and reliable operation is directly related to the economic benefits of coal enterprises. The traveling box is a key component of the coal shearer. Since the traveling box is driven by an open gearbox, the gear chamber is directly connected to the underground coal mining face. Extremely harsh, complex and changeable stress conditions, heavy maintenance work during use, and gears often fail due to severe wear. In addition, the tract...
