XY-4T tower crane integrated drilling rig Ⅰ. Application Scope The XY-4T core drill rig, integrated rig with tower into one unit, consists of XY-4 drill rig and mast-type drill tower, with the function of hydraulic lifting and lowering of tower. The rig is simple in structure, reasonable in design, light in weight, easy to operate; it is in a wide range adjusting angle. It is especially suitable for drilling of hole with great slope angle. XY-4T tower-crane integrated core drilling rig is suitable for diamond and cemented carbide drilling of solid deposits, as well as for engineering geology, shallow oil, natural gas, and groundwater drilling, as well as for hydrological wells, tunnel ventilation, drainage and dam grouting It is especially suitable for drilling inclined holes with a drilling depth of less than 800m and a range of 45-90°. Technical Features
1. The tower adopts a four-edged mast assembly structure, ground installation, and hydraulic lifting of the tower. When the main engine moves back and the vertical shaft leaves the orifice, the movable pulley block of the crane can move forward, which can compensate for the backward movement of the main engine. The drilling tower can also adjust the angle clockwise for inclined hole operation.
2. The drilling rig has more speed series (8 stages) and a reasonable speed range, and the low speed torque is large. Therefore, the drilling rig has strong technological adaptability and a wide range of use, which is not only suitable for small-diameter diamond core drilling, but also meets the requirements of large-diameter carbide core drilling and some engineering drilling.
3. The drilling rig is light in weight, good in disassembly, easy to relocate, and suitable for operation in mountainous areas.
4. The structure is simple and the layout is reasonable, which is convenient for maintenance, maintenance and repair.
5. The drilling rig has two reverse rotation speeds, which is convenient for accident handling.
6. The center of gravity of the drilling rig is low, the fixing is firm, the moving vehicle is stable, and the stability is good when drilling at high speed.
7. The instrument is complete, which is convenient for the observation of various drilling parameters.
8. The operating handle is centralized, easy to operate, simple and flexible.
9. The mud pump is driven independently, and the power configuration and airport layout are more flexible.
