The YBJ-500C explosion-proof laser alignment instrument for mining is an integrated device that combines electronic, optical, and precision mechanical technologies. The instrument is designed for fixed installation and can be quickly secured to anchor bolts using a suspension assembly. It offers arbitrary coarse adjustment over a 360° range with fine, high-accuracy adjustments; adjustment is convenient, and the braking mechanism is reliable. The product features a self-developed optical system and supports both red and green light sources, with beam spot size and effective range tailored to meet the requirements of underground mining operations. It is powered by a AC–DC conversion power module that accepts a wide-range AC input of 127 V and includes protective functions. The instrument is primarily used in coal mine roadways during excavation to provide precise positioning of center and waist lines, as well as directional guidance for the installation of transport pipelines, conveyor belts, ventilation ducts, water pipes, and cable routes. It can also provide straight-line guidance for tunneling in subways, highways, railways, bridges, tunnels, culverts, oil pipelines, and drainage projects. By integrating the power module, optical components, and precision mechanics into a single unit, the instrument boasts an aesthetically pleasing appearance, compact size, and lightweight design. Coarse adjustment is achieved via a 360° rotatable locking mechanism, while installation is facilitated by a fixed mounting rod and a suspension assembly with locking devices, making instrument fixation both convenient and rapid. A fine-adjustment mechanism allows for lateral and longitudinal adjustments within a range of no less than ±1.5°. After being connected to a 127 V AC power supply, the power module converts the voltage to DC to power the laser tube, generating a laser beam; this beam is then collimated and directed over long distances by the optical system, achieving an effective range of up to 500 meters.
