Generally, a reducer used by a coal mine scraper consists of a pair of arc bevel gears, a pair of helical gears and a pair of spur gears to form a three-stage reducer; during assembly, industrial gear oil is required to be injected into the speed reducer, and the injection amount is 1/3 of the circular arc bevel gear when the speed reducer is in the horizontal position, so that the transmission lubricity between gears in a working state is ensured; in the fully-mechanized mining process, because the inclination angle of the scraper conveyor is continuously adjusted along with the extension of the excavation surface, the speed reducer fixed on the scraper conveyor can also incline therewith, the industrial gear oil in the speed reducer cannot meet the lubricating effect among the gears of the group at the moment, abnormal sound, oil leakage and gear abrasion of the speed reducer are often caused, and the phenomenon of shaft breakage even occurs, so that the working operation efficiency and the service life of the scraper conveyor can be seriously influenced.
The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art that is known to a person skilled in the art.
Disclosure of Invention
The utility model aims to provide a quick leveling mechanism for a speed reducer of a scraper conveyor, and aims to solve the technical problem that the fault of the scraper conveyor is caused by the conditions of insufficient lubrication, gear oil leakage, serious abrasion among gears and the like of the speed reducer easily caused by the inclination of the angle of the speed reducer in the fully mechanized mining process of a coal mine.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the quick leveling mechanism for the scraper conveyor speed reducer comprises a rack and a speed reducer mounting seat, wherein the speed reducer mounting seat is fixedly arranged on the rack, and the quick leveling mechanism also comprises leveling grooves which are fixedly arranged on the rack and correspondingly arranged along two sides of the speed reducer mounting seat; the leveling groove comprises a first leveling groove used for adjusting the inclination angle of the speed reducer and a second leveling groove used for bearing the weight of the speed reducer.
Preferably, the leveling groove is of a square groove structure.
Preferably, the included angle between the central axis of the circular groove and the vertical direction is 11-13 degrees.
