The invention discloses a courtyard hob with an oil storage compensation balance system and an oil injection method, the courtyard hob comprises a wheel body, a wheel shaft, a bearing assembly and a sealing assembly, the bearing assembly and the sealing assembly are arranged between the wheel body and the wheel shaft, and a containing groove matched with the sealing assembly and the bearing assembly is formed between the wheel shaft and the wheel body. According to the raise hob with the oil storage compensation balance system and the oil injection method, suction is generated in the bearing assembly through vibration of the hob, meanwhile, slurry pressure acts on the oil storage bag, and lubricating oil in the oil storage bag continuously enters the containing groove through the oil guide channel to lubricate the bearing assembly; the oil storage bag is used for balancing the pressure difference inside and outside the containing groove when the hob wheel body works, so that the sealing assembly can normally work for a long time under the small inside and outside difference, drilling fluid is prevented from entering the containing groove, leakage of lubricating fluid is avoided, and enough lubricating grease can be stored to be continuously supplemented into the containing groove; and the bearing assembly is in a sealed state and works under a good lubrication condition.
Description
technical field [0001] The invention relates to the technical field of patio hob, in particular to a patio hob with an oil storage compensation balance system and an oil injection method. Background technique [0002] As an important mining equipment and important equipment for hydropower station construction, raise drilling rig is widely used in underground transportation tunnels and wellbore construction with stable geological conditions. The drill rod and the drill bit are driven to rotate, and at the same time, the propulsion cylinder applies the drill bit to propulsive force during drilling, and applies the cutter head to reverse the lift force and act on the rock during hole reaming. The patio hob is the most important rock-breaking tool, and the quality of the patio hob reflects the quality of the patio drilling. [0003] The quality of the patio hob is related to the quality of bearing lubrication and the reliability of the seal. The bearing lubrication and the amou...
