Abstract

The invention discloses a bidimensional orientating device for a coal mine underground roadway, which is composed of: a marking mechanism, a rotation mechanism, an indicating mechanism, an isolation mechanism and an assistant mechanism. The marking mechanism is composed of a longitude and latitude sphere shell (1), longitude scales (2) and latitude scales (3); the rotation mechanism is composed of a rotatable shell (4) and a warpwise groove (5); the indicating mechanism is composed of a screw rod pointer (6), a control nut (7), a telescopic rod (11) and a leveling ball (15); the isolation mechanism is composed of a control handle (8), a control panel (9) and an isolation ball (10); the assistant mechanism is composed of a connection board (12), an adjustable connection rod (13), an adjusting nut (14) and the leveling ball (15). The bidimensional orientating device works in a dead zone of a theodolite or a total station instrument and overcomes the defects of the theodolite or total station to some degree, avoids tunneling into an abandoned roadway and avoids safety and economic loss caused by constructing a waste hole and mis-penetrating a wasted and abandoned roadway.

Description

technical field [0001] The invention relates to an instrument used in underground coal mines, in particular to a measuring instrument used in underground tunnels of coal mines, that is, a two-dimensional orientation device for underground tunnels in coal mines. Background technique [0002] At present, in the blind area of ​​the theodolite or total station, if the design orientation cannot be given in time and accurately, it will be impossible to avoid excavation of abandoned roads, unavoidable construction waste drilling, and unavoidable safety losses and economic losses caused by misleading old empty roads. Contents of the invention [0003] The invention overcomes the disadvantages of the original device, can give the design orientation timely and accurately, works in the blind area of ​​the theodolite or the total station, can make up for the deficiency of the theodolite or the total station to a certain extent, avoids the waste roadway excavation, and avoids constructi...
