The intrinsically safe laser pointer for coal mines uses a semiconductor laser as the light source. It has a portable structure, low power consumption, good beam quality, small size, light weight, easy to install and use. Simple, stable and reliable performance, this product's unique integrated design greatly facilitates installation and adjustment. The product is equipped with an intrinsically safe DC power supply, suitable for factories without AC power supply or frequently moved places, and can work continuously for >
The main uses and scope of application of intrinsically safe laser pointers for type coal mines are:
The pointers are widely used for pointing and positioning the direction of advancement of the tunnel boring machine during tunnel excavation, for guidance and control of the positioning of fully mechanized mining working faces in coal mines, and Positioning and alignment of highways, railways, tunnels, culverts, bridges, high-rise buildings, and pipeline installations, especially suitable for underground use in coal mines with explosive gas environments.
Environmental conditions for use of intrinsically safe laser pointers for coal mines:
Ambient temperature: -℃～+℃
Relative humidity:
Storage temperature: -℃～+℃
Ambient atmospheric pressure: ~
Dimensions:
In coal mines containing explosive gas (methane) and coal dust explosion hazards
In an environment without gas or steam that significantly damages the insulation:< br/> Working principle of intrinsically safe laser pointing instrument for coal mines:
The pointing instrument is driven by a DC power supply to emit a laser beam from a low-power semiconductor laser, which is converged by a universal optical system to turn it into a laser beam with good collimation. By adjusting the horizontal and vertical fine-tuning, it plays the role of alignment and pointing.
