Abstract
Disclosed is a pre-warning safety detector of a top plate. Existing top plate layer separating devices which are installed and used in coal mine tunnels use scale displacement readings arranged on top plates to indicate the sinking amount of top plates of tunnels. The main defects of the existing top plate layer separating devices include that due to the fact that tunnels are high, observation personnel can not observe the readings easily, the observation is achieved only under the condition that the observation personnel stands on high benches or ladders, inconvenience is caused for the observation personnel and the personnel usually suffers from safety accidents such as fall damage. The pre-warning safety detector of the top plate comprises a top plate layer separating device (3), wherein the top plate layer separating device (3) is installed on a coal mine tunnel shed top (2) through a connecting plate (1), the top plate layer separating device is connected with an intelligent display (5) installed at a position of 1.6 meters high on a tunnel through a data line (4). The pre-warning safety detector is used for safety detection of coal mine tunnel top plates.
Description
Technical field:
the utility model relates to a kind of early warning type roof safety detector.
Background technology:
The roof delamination appearance that
present coal mine roadway is installed and used; All be to utilize the scale displacement readings that is installed on the top board to show the deflection of back; The major defect of its existence be the tunnel than higher, the observation personnel are difficult for its reading of observation, often need stand on stool or the ladder and carry out; Bring many inconvenience for the observation personnel, security incidents such as tumble injury often take place; Personnel are in observation process in part observation, follow the line of least resistance, dislike trouble, save the strength, and do not remove stool, at will deal with assignment from following reading; Sometimes the scene does not just have stool at all and can seek, and brings inconvenience for the observation personnel; Be installed in the sight gauge on the top board, scale is little, sees from the bottom up when personnel observe, and in same level, error in reading is not bigger for sight line and scale; This instrument does not have the acousto-optic warning function, even the amount of crushing reaches maximum limit, is not the observation personnel, does not know that top board has the danger of sinking roof fall yet, tends to damage to the personnel that just walk at this place.
Summary of the invention:
The purpose of
the utility model provides effective, the sensitive early warning type roof safety of a kind of warning detector.
Above-mentioned purpose realizes through following technical scheme:
a kind of early warning type roof safety detector, its composition comprises: be installed in the roof delamination appearance of coal mine roadway ceiling through junction plate, described roof delamination appearance is through data wire connection of intelligent display.
described early warning type roof safety detector, described intelligent display connects on the coal mine roadway side wall through junction plate, and described intelligent display has alarm and alarm lamp.
Beneficial effect:
Improve present roof delamination appearance
1. the utility model; Help 1 in the lane. intelligent display is installed in 6 meters high position; The method that on top board, observe changes in the lane helps observation; The scale signal that is about on the top board is transferred to the intelligent display that help in the lane through the signal of telecommunication, to make things convenient for personnel's observed reading.
the utility model can be set the roof delamination limiting value on intelligent display; Can arbitrarily carry out the setting of danger warning value according to different geological condition, top board lithology, technical requirements,, early warning numerical value is set according to top board condition and experimental data; This instrument is had under the dangerous situation of roof fall at top board; In time send sound and light signal through alarming horn and alarm lamp, prevention personnel pass through from this, avoids personnel to cause injures and deaths.
the utility model shows that with scale changing intelligent digital into through the signal of telecommunication shows, and is directly perceived, accurate, reduces personnel's error in reading; Be convenient to administrative staff's inspection and supervision, the phenomenon that reduces or avoid some of the staff to practise fraud.
the utility model is hung intelligent display in the lane and is helped, and like this, the observation personnel just need not stand on stool or the ladder and on top board, observe, and have reduced the trouble of removing stool or ladder.
Description of drawings:
accompanying drawing 1 is the structural representation of this product.
The specific embodiment:
Embodiment 1:
a kind of early warning type roof safety detector, its composition comprises: be installed in the roof delamination appearance 3 of coal mine roadway ceiling 2 through junction plate 1, described roof delamination appearance is through data wire 4 connection of intelligent displays 5.
Embodiment 2:
Embodiment 3:
Claims (2)
1. early warning type roof safety detector; Its composition comprises: be installed in the roof delamination appearance of coal mine roadway ceiling through junction plate, it is characterized in that: described roof delamination appearance is mounted on the lane through data wire and helps 1. the intelligent display of 6 meters high positions.
2. early warning type roof safety detector according to claim 1 is characterized in that: described intelligent display connects on the coal mine roadway side wall through junction plate, and described intelligent display has alarm and alarm lamp.
