Problems solved by technology
At present, exploration tasks with special requirements such as geological prospecting, mountain-crossing expressways, and railway tunnels are usually located in steep mountains, but the maximum climbing angle of crawler-mounted drilling rigs is only 30°, which is not suitable for mountainous areas and difficult to access. The location of the hole, and the price of the crawler truck-mounted drilling rig is usually more than 10 times that of the ordinary core drilling rig, which greatly restricts its popularization

Embodiment 1
[0039] Such as Figure 1-7 As shown, the rigless drilling method with adjustable drilling inclination is based on a core drilling machine, which includes a drilling machine body 11, a power unit, a winch 12, a gearbox, a vertical shaft housing 13 and a vertical shaft 14. The power unit, the winch 12 and the gearbox are all fixedly installed on the drilling rig body 11, the hoisting machine 12 is wound with a steel wire rope 121, the end of the steel wire rope 121 is connected with a lifter 122, and the vertical shaft shell 13 is detachably connected to the drilling rig body 11. The included angle between it and the horizontal plane can be adjusted between 0~360 °, and the vertical shaft 14 is installed in the vertical shaft casing 13, adjusts the angle between the vertical shaft casing 13 and the horizontal plane to realize the adjustment of the angle between the vertical shaft 14 and the horizontal plane. The power generated by the power unit is transmitted to the vertical sh...

A drilling-tower-free drilling method with adjustable drilling inclination is based on a rock core drilling machine, and the rock core drilling machine comprises a drilling machine body, a power device, a winch, a gearbox, a vertical shaft shell and a vertical shaft. The drilling method comprises the following steps: 1, early-stage installation work; 2, installation of a guide wheel A and a guidewheel B; 3, starting of drilling; 4, pulling out of a drill; 5, adding of a new drill rod; 6, drilling; 7, completing of the connection of the new drill rod; and 8, restarting of drilling. The two guide wheels are used for changing the pulling force (pulling out) direction or the pushing force (drilling down) direction of a steel wire rope; and the drilling method overcomes the defect that a traditional rock core drilling machine cannot drill down and pull out smoothly when the drilling inclination is too large, achieves efficient drilling at any angle ranging from 0 degree to 90 degrees (namely the rock core drilling machine is completely horizontal to completely vertical), and has wide market application prospects.
Description
technical field [0001] The invention relates to a geological drilling method, in particular to a drilling tower-less drilling method with adjustable drilling inclination. Background technique [0002] Geological and mineral exploration and engineering geological exploration usually need to use core drilling rigs to complete, and the problem of drilling inclined holes may be encountered during actual operation. [0003] When the existing core drilling rig is installed and used, it is first necessary to determine the drilling position, level the site, assemble the drilling tower, the crown block pulley of the drilling tower is above the center line of the drilling hole, and then adjust the vertical shaft of the drilling machine to the alignment hole position. If you meet the technical requirements for drilling inclined holes, you can only adjust and fix the angle of the vertical shaft within 30° before drilling (that is, the adjustment amount based on the vertical line is ±30...
