Description
Technical field
The utility model relates to Coal Mine pressure monitoring technical field, is specifically related to a kind of measurement monitoring the displacement of coal mine roadway coal side
Device.
Background technology
Coal side surface displacement changing value is an indispensable part in ore pressure monitor, traditional coal mine roadway coal side surface displacement
Measuring through frequently with manual measurement, generally use laser range finder or tape measure, this measuring method exists inevitably
Human error is often measured inaccurate, and when having multiple measuring point, survey crew's labour intensity is bigger.
Utility model content
The purpose of this utility model is mainly for solving above-mentioned technical problem, and provides a kind of coal mine roadway coal of monitoring to help displacement
Measurement apparatus.
The utility model includes coal mine tunnel top board and coal mine roadway coal side, the measurement dress of described monitoring coal mine roadway coal side displacement
Put and include L-type pointer, Measure Board, a pair Measure Board fixed beam and a pair pallet, described L-type pointer by connecting plate and
One group of rivet is fixedly mounted on coal mine roadway coal and helps, and described Measure Board is provided with scale and regulation long location hole, the pair of torr
Dish is fixedly mounted on coal mine tunnel top board by one group of rivet respectively, and one end of the pair of Measure Board fixed beam is solid respectively
Dingan County is contained on a pair pallet, the adjustable other end being arranged on a pair Measure Board fixed beam of described Measure Board, and L-type refers to
The needle point of pin points to the scale of Measure Board.
The regulation long location hole of described Measure Board is by the adjustable other end being arranged on a pair Measure Board fixed beam of pair of bolts.
Under monitoring original state, the needle point of L-type pointer points to 0 graticule of Measure Board scale.
The pair of Measure Board fixed beam uses shape to make.
The utility model advantage is: the utility model is drawn materials simply, cheap, it is easy to operation, not only can effectively keep away
Exempt from human error, and the labour intensity of survey crew can be greatly reduced, there is good practical value.

Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is described further.
As it is shown in figure 1, the utility model includes coal mine tunnel top board 1 and coal mine roadway coal side 2, described monitoring coal mine roadway coal
The measurement apparatus of side displacement includes L-type pointer 3, Measure Board 4, a pair Measure Board fixed beam 5 and a pair pallet 6, described
L-type pointer 3 is fixedly mounted in coal mine roadway coal side 2 by connecting plate and one group of rivet, and described Measure Board 4 is provided with scale
With regulation long location hole 4-1, the pair of pallet 6 is fixedly mounted on coal mine tunnel top board 1 by one group of rivet respectively, described
One end of a pair Measure Board fixed beam 5 is respectively and fixedly installed on a pair pallet 6, and described Measure Board 4 is adjustable to be arranged on
The other end of a pair Measure Board fixed beam 5, and the scale of the needle point sensing Measure Board 4 of L-type pointer 3.
The regulation long location hole 4-1 of described Measure Board 4 is arranged on a pair Measure Board fixed beam 5 by pair of bolts 7 is adjustable
The other end.
Under monitoring original state, the needle point of L-type pointer 3 points to 0 graticule of Measure Board 4 scale.
Working method and principle: this device utilizes a pair Measure Board fixed beam, rivet, a pair pallet to be fixed on by rule
As geo-stationary point on the midpoint of coal mine tunnel top board, L-type pointer is fixed on Mei Bang midpoint, tunnel the shifting as coal side
Dynamic point, is alignd 0 graduation mark of Measure Board with pointer by regulation scale plate regulation long location hole, then by pair of bolts mark
Chi plate is fixed, by observation pointer corresponding to value produce coal side surface displacement changing value.
