Novel mining laser range finder

Abstract

The invention discloses a novel mining laser range finder. The novel mining laser range finder consists of a lens cleaning device, a data acquisition device, a supporting device and a fixed device, wherein the lens cleaning device comprises an infrared raindrop sensor, a conveying pipe, a built-in spray head, a wiper and the like, the laser lens can be cleaned to ensure that laser signals are notblocked by coal dust on the surface of the lens; the data acquisition device comprises a seal housing, a laser emitting end, a laser receiving end, a laser lens, a horizontal retainer, an operation controller and a transmission cable, the laser emitting end and the receiving end are mounted in the horizontal retainer to ensure horizontal emission of the laser signals; the supporting device comprises a supporting rod, bolts and the like and plays a supporting role in the novel mining laser range finder; the fixed device comprises a reflecting groove and other fixed components, and the reflecting groove can be fixed to the upper part of a roadway. According to the novel mining laser range finder, when the roadway inclines, automatic leveling can be realized, the measurement precision is guaranteed, meanwhile, the lens coal dust is automatically wiped, the service life is long, and the monitoring is stable.

Description

technical field [0001] The invention belongs to the field of deformation measurement of surrounding rocks in mining engineering, and in particular relates to a novel mine-used laser range finder. Background technique [0002] With the increase of coal mine mining depth, the roadway is under the action of "three highs and one disturbance", and the roadway converges and deforms violently. The specific performance is that the roof sinks a lot, the floor bulges and the two sides converge seriously. , leading to a series of problems such as blocked passage of personnel, difficulties in smooth transportation of materials, and blocked ventilation of roadways, which seriously restrict the safe production of coal mines. In order to solve such problems, it is necessary to explore the law of convergence deformation of surrounding rock and formulate corresponding control measures. Therefore, obtaining the law of deformation of surrounding rock is the most critical step. At present, the...
