I. Overview

1 ．Product Features

YBJ The explosion-proof laser pointer for mining is an instrument that integrates electronics, optics, precision mechanics, and other technologies. It features an aesthetically pleasing appearance, compact size, light weight, and explosion-proof characteristics. The instrument is installed in a fixed configuration and can be quickly secured to anchor bolts using a suspension assembly. The instrument can 360° The range can be coarsely adjusted arbitrarily and finely tuned with high accuracy; adjustment is convenient and braking is reliable. The product features a self-developed optical system and supports both red and green light sources, with spot size and effective range tailored to meet the requirements of underground mining operations. The instrument is equipped with an AC/DC switching power supply module that accepts a wide AC input voltage. AC80V ~ AC245V Power supply with protection function.

II. Structural Features and Operating Principle

1 ．Structural features:

The instrument integrates the power supply module, optics, and precision mechanics into a single unit, featuring an aesthetically pleasing appearance, compact size, and lightweight construction.

Instrument coarse adjustment uses 360° The rotatable locking mechanism features a fixing rod and a suspension assembly with a locking device, making instrument installation more convenient and efficient. The instrument can be finely adjusted via a micro-adjustment mechanism to achieve a range of no less than ±1.5° Make fine horizontal and vertical adjustments within the scope.

2 ．Working principle:

Connect the instrument to the supply voltage. AC127V Subsequently, the power supply module converts the input power into a DC voltage to supply the laser tube, generating a laser beam. This beam is then directed over long distances via an optical system, with a range of 1500 Rice.

IV. Installation, Adjustment, and Use

1 ．Installation

（ 1 ) First, take one φ20 ~ 22 Millimeter-diameter rock bolts (provided by the user) are installed and anchored into the roadway roof.

（ 2 ) Pass the mounting rod through the mounting bracket, then use a wrench to tighten the bolt and secure the instrument to the mounting rod.

（ 3 ) Thread the anchor bolt mounting holes in the suspension assembly onto the anchor bolts previously installed in the roadway roof, then tighten the lock nuts to secure the assembly.

2 ．Adjustment and use

Power Connection: Ensure that the supply voltage is within the AC range specified on the nameplate. Under no circumstances is it permitted to open the enclosure while energized in underground operations!

Connect the instrument’s power cable and ground wire to the correct terminals, verify that all connections are secure and there are no short circuits, then tighten all securing screws before powering on and illuminating the device.

（ 1 ) Perform coarse adjustments of the instrument in the horizontal and vertical directions as required by the aiming of the measuring instrument.

Horizontal coarse adjustment: Loosen the set screw, rotate the instrument along the anchor rod to align the laser beam in the horizontal plane to the desired position (centerline), then tighten the set screw.

Vertical coarse adjustment: Loosen the bolt, slide the instrument along the mounting rod to align the laser beam in the vertical direction to the desired position (at the waistline), then tighten the bolt.

（ 2 ) Then, precisely adjust the direction of the laser beam according to the project requirements, as follows:

Horizontal adjustment: Rotate the left and right horizontal adjustment screws in the same direction simultaneously to move the light spot horizontally; once properly adjusted, lock both screws.

Vertical adjustment: Rotate the upper and lower vertical adjustment screws in the same direction simultaneously to move the light spot vertically. Once properly adjusted, lock both screws.

  Please note: After the spot has been accurately adjusted in both the horizontal and vertical directions, the adjustment screws must be locked simultaneously. The instrument is factory-calibrated to ensure the spot remains within the specified range, so no on-site adjustment is required by the user. If adjustment is nevertheless necessary, please follow the procedures outlined in the troubleshooting section.

V. Safety Warnings

1 ．Do not look directly at the light-emitting window!

2 ．Absolutely no opening the cover while energized!

VI. Maintenance and Servicing

1 . When the instrument is not used for an extended period, it should be stored in a dry, non-corrosive environment.

2 ．The optical system is calibrated before the instrument leaves the factory; do not disassemble it arbitrarily. During transportation, handle with care to avoid severe vibration.

3 . The instrument shall be operated at the specified input power voltage, and both internal and external grounding must be reliable.

4 ．Live maintenance is prohibited; when it is necessary to open the enclosure for maintenance, such work must be performed in a safe location.

5 ．The window glass of the laser output port should be regularly wiped with lens paper or a soft cloth to ensure the surface is clean and free of dust.

6 During maintenance and repair, the instrument must never be opened while energized. The explosion-proof surfaces must be protected from damage. The models, specifications, and parameters of components must not be altered at will. Measures must be taken to prevent loss of explosion protection: avoid damaging the explosion-proof surfaces; ensure that the fasteners on the junction box cover are securely tightened; do not lose the sealing rings in the cable entry devices; and properly tighten the compression screws, among other precautions. When installing the explosion-proof surfaces, apply anti-rust oil; verify that the adjustment mechanisms operate smoothly and that locking is reliable; inspect the sealing-ring fasteners; and replace any damaged parts promptly.

VII. Fault Analysis and Troubleshooting

“ The instrument is not working. ” Please inspect your instrument according to the table below. If the instrument still does not function properly after inspection, please contact a service center or the manufacturer.

VIII. Maintenance Services

1 . In principle, the maintenance of explosion-proof electrical products shall be carried out by the product manufacturer.
