ZYJ-400/280 column hydraulic rotary drilling rig, hydraulic rotary drilling rig

Description :

　　The ZYJ-400/280 column hydraulic rotary drilling rig uses hard alloy, diamond composite drill bits, and efficient spiral drill rods with coal drill bits for rotary drilling. It is suitable for advanced gas and water detection drilling on rock and mining faces, with drilling depths ranging from 50 to 70 meters. Equipped with supporting and fixed guide rails, the pillar adopts a top tightening method, and a 360 degree adjustable connecting plate is used between the guide rail and the pillar to ensure a 360 degree adjustable hole angle.

　　The ZYJ-400/280 column hydraulic rotary drilling rig adopts a hydraulic transmission mechanism, which has high drilling capacity, fast speed, simple operation, stable and reliable work, and easy movement and installation. Fully automatic top tightening system, stable and reliable, accurate drilling, high precision. Automatic hydraulic control, infinitely variable speed, easy operation, and long distance. The drilling rig has the characteristics of fast rock breaking speed, long drilling distance, time-saving and labor-saving, and high work efficiency.

　　ZYJ-400/280 column hydraulic rotary drilling rig applicable scope

　　ZYJ-400/280 column hydraulic rotary drilling rig is suitable for top blasting holes, drainage holes, gas drainage holes, grouting holes, address exploration holes, and other engineering holes. Suitable for various coal seams and rock formations with a rock strength system f ≤ 10. The drilling rig can drill any hole within the azimuth and inclination range specified in the basic parameter table. Can be used with various forms and specifications of drilling tools, suitable for different drilling requirements.

　　Structural characteristics of ZYJ-400/280 column hydraulic rotary drilling rig

　　The ZYJ-400/280 column hydraulic rotary drilling rig is mainly composed of a pump station, a main engine, an operation console, and drilling tools; Easy to install, disassemble, and move. The pump station is driven by an explosion-proof motor to rotate the oil pump, converting electrical energy into hydraulic energy (pressure oil) for the rotating oil circuit and propulsion oil circuit. The pressure oil is then transmitted to the hydraulic actuator through the one-way valve and directional valve group on the control panel, thereby achieving various functions of the drilling rig. The operation is simple and practical.

　　The structural design is scientifically reasonable, with small size, light weight, fast disassembly, and easy use. Fully automatic top tightening system, stable and firm, accurate drilling, high precision. Automatic hydraulic control, continuously variable transmission, easy operation, and long distance. The host has a small footprint, adapts to various complex environments, and can drill engineering holes in various directions and angles. The drilling rig has fast rock breaking speed, long drilling distance, time-saving and labor-saving, and high work efficiency.
