    ???? product detail presentation

    Tunnel rig

    Full range

    Tunnel drilling rig refers to the full hydraulic tunnel drilling rig for coal mines. The fully hydraulic tunnel drilling rig for coal mines mainly uses cemented carbide and diamond composite drill bits for rotary drilling. Our company's main production specifications are: ZDY-660, ZDY-1200, ZDY-2000S.

    Fully configured and safe

    The coal mine tunnel rig uses a full hydraulic structure, which is divided into three parts: the main machine, the pump station and the console. The main machine is a split structure.
    Can be further disassembled for easy handling.

    01 uses
    Wide range of applications

    Tunnel drilling rigs are mainly used for drilling gas drainage (drainage) holes, anti-outburst holes, grouting fire extinguishing holes, coal seam water injection holes, geological exploration holes and other engineering holes in coal mines. They are particularly suitable for near-300 horizontal holes in coal mines and Allows use of 900.

    02 Power
    Strong transmission capacity, stable and reliable operation

    Tunnel rig adopts hydraulic transmission mechanism, which has the characteristics of large drilling capacity, fast speed, simple operation, stable and reliable work, and convenient mobile installation.

    Wide range of uses

    Tunnel rigs are divided into two types of derrick and stand, which are adapted to local conditions. Equipped with a high-pressure water generator and a high-pressure sealed drill pipe, the drilling rig can cut seams with low gas permeability, thereby improving gas drainage efficiency and greatly shortening drainage time.

    ???? Product specification

    ????????????????,??????????,??????????????????????? Before installing and driving, check whether the drilling rig is installed smoothly and reliably, and whether the fasteners are loose. Check if the oil level in the hydraulic oil tank in the gearbox is insufficient.

    ?????????,?????????,???????????????,?????????????? Details When tightening the drill rod with a moving chuck, tighten the tile bolts evenly, and check the length of the tile bolts exposed from the chuck body to prevent the tile bolts from touching the feed cylinder.

    ?????????????????????????????????,????? Every time you start, you should check the direction of rotation of the motor, whether the water supply device is flexible, and whether the water supply hose is fixed to prevent rotation.

    ????????????????????????,???????? There are abnormal sounds, vibrations, heat and oil leakage during the turning process. Stop and check immediately.

    ?????????????? The two brakes of the brake winch cannot be braked simultaneously.
