Description
Technical field
The present invention relates to a kind of geological drilling equipment, be specifically related to a kind of hydraulic-driven deep hole rock-core borer for Science Drilling.
Background technology
Along with the development of national economy, the demand of various SOLID MINERAL RESOURCES is increased day by day, people find available resources at the more depths of having to earth's surface; The needs that also have some geological sciences probings, meet the detection of the mankind to earth deep tissue structure, to understand in time the motion change of the earth's crust, can make early warning timely to geological disasters such as earthquakes, reduce the loss that disaster is brought.All need enough abilities and facilitate durable drilling equipment to equip, will have the ability of drilling deep hole, have again the ability of boring relatively large diametric hole.But, can meet rig that the deep hole of these two kinds of abilities can core few.
At present, traditional rock-core borer mainly comprises mechanical spindle-type core drill and hydraulic power hair style rock-core borer.Machinery spindle-type core drill adopts motor or internal combustion engine that power is provided mostly, drives gyrator, the hoist engine operation of rig by machine driving forms such as clutch, gearbox, transfer cases, drives feeding system operation by hydraulic drive.Deep hole rock-core borer requires large to power, traditional machine dimensions drill is subject to mechanically operated restriction and can not infinitely amplifies, not only heavy, and various operating grips are apart from dispersion, rig operating personnel inconvenience manipulation, and operating grip needs very large operating physical force, labor strength increasing.Do not bore ginseng and show and report to the police, in deep well drilling process mesopore, accident probability is larger; Because the main executive component of mechanical spindle-type core drill is machine driving and speed change, cause that its transmission efficiency is lower, gear is complicated, thereby caused the defect of the large poor efficiency of energy consumption; And hydraulic cylinder feed system is limited by hydraulic cylinder travel, need frequent fall bar, easily cause core plugging at the bottom of hole, service working time is lengthened, and gyrator can not double as unloading instrument, the operating efficiency of mechanical spindle-type core drill and job safety performance are limited by very large.
Hydraulic power hair style rock-core borer, its revolution, feed with the mechanism such as lifting drilling tool and all drive with hydraulic driving mode, be generally crawler belt or vehicle loading, emphasize the mobility of rig, more applicable for medium and shallow boring, there is following defect for deep well drilling: mast is few compared with the drill string of short each extraction, the non-cutting time while having increased drilling and workman's labour intensity;
Be greater than mechanical spindle-type core drill although it feeds stroke, it is still less that it feeds stroke, can not meet deep drilling requirement, increase the number of times that adds stacks, and cleaning bottom of hole that can not long stroke, increase the risk of boring collapse hole and bit freezing, increase working time and operating cost; Unit head can be realized high speed rotary to meet the requirement of small-bore diamond drilling technique, but large diameter requirement can not meet deep well drilling perforate time, and moment of torsion is inadequate.
