Roadway roof and floor dynamic instrument and construction method thereof

Abstract

The invention discloses a roadway roof and floor dynamic instrument and a construction method thereof. The roadway roof and floor dynamic instrument is composed of a top base, a rotating device, a displacement rod, an anti-impact-wave sleeve, a driver, a comprehensive dial plate, a constant-damping hydraulic device and a base. The top base is fixed on a top plate, and a hemispherical clamping groove formed in the center is connected with the rotating device. The upper end of the displacement rod is fixedly connected with the rotating device, and the lower end is sleeved by the anti-impact-wavesleeve. The anti-shock wave sleeve is a concave circular triangular sleeve, so that the influence of blasting impact waves is reduced; the driver is a drive mechanism and is connected with the anti-impact-wave sleeve; the comprehensive dial plate is fixed to the side face of the driver and can display the approaching amount of the top plate and the bottom plate; meanwhile, an alarm device is arranged and can give an alarm sound and light when someone approaches in a certain distance range to prevent personnel collision; a constant damping hydraulic device is connected with the anti-impact-wave sleeve and the rotating device up and down and is provided with a pressure release valve, compression and resilience of a displacement rod are guaranteed; and the rotating device is connected with the base fixed to the bottom plate.

Description

technical field [0001] The invention relates to a roof and floor dynamic instrument, in particular to a roof and floor dynamic instrument used in the roadway monitoring field and a construction method thereof. Background technique [0002] In recent years, with the continuous improvement of mining technology, my country's mineral industry has developed better and faster. With the continuous increase of mining depth, the pressure of mines is more obvious, and the disasters caused are becoming more and more serious, such as roof collapse. Accidents such as roadway deformation and rock pressure impact occur frequently, which have become important factors affecting production safety and seriously threaten the production safety of mining and the safety of employees. As the main component of the mine production system, the roadway is responsible for the important tasks of normal production, transportation, ventilation and pedestrians of the entire mine. The relative stability of t...
