Described laser instrument 4 is cylindrical, and head has flange arrangement, and three screws 402 established for 401 1 weeks by ring flange.
Described laser holder 8 is fixed on enclosure interior, has the circular groove 801 matched with laser instrument upper flange plate, and the screw 2 802 being equipped with aperture 803 at center and matching with ring flange.
Described laser holder 8 and ring flange 401 tabling on laser instrument are also fastening by three sunk screws 403, and the degree of tightness of adjustment three screws makes the laser beam axis of laser instrument and housing set up correspondence position relation.
Described measuring instrument is powered by power module 2.
The design's tool housing adopts engineering plastics manufacture, and apparatus measures part adopts micro electronmechanical angular transducer as core parts, LCD liquid crystal digital display (with back lighting).Instrument internal is equipped with semiconductor laser, because laser instrument profile have employed the mounting structure of designed, designed, easy to adjust when making to install instruction, the effective overall precision that improve instrument.Instrument entirety adopts explosion-proof (essential safe type) project organization, and instrument adopts hermetically sealed design, and integral protection grade can reach IP66, meets underground coal mine requirement of explosion proof.
Beneficial effect
Because instrument have employed engineering plastics shell, save copper material, aluminium, the overall weight of instrument reduces 2/3, light instrument decreases the pressure to lining rope in measuring process, decreases the pseudo-angle of lining rope to the impact of measuring, decreases the part of machining in instrument processing process, instrument assembling is also simple many, easy to carry.Because instrument have employed the feature of numerical monitor in its precision, stability, carry, measure the various aspects such as operation and all will obviously be better than dial type tilt gauge.
