Description
Technical Field
The invention relates to a rope coring drilling tool suitable for large-caliber horizontal engineering geological exploration.
Background
With the deep development of national strategic super engineering Chuangzang railway construction, engineering geological exploration faces new challenges. The geological conditions of the Chuanhang railway engineering are complex, the construction risk is high, and the existing equipment cannot adapt to the geological conditions at high altitude, so that the comprehensive geophysical prospecting geological forecast precision is low. And coring by horizontal drilling is a more intuitive method of geology exploration. Therefore, the research on long-distance, large-caliber, near-horizontal and high-precision drilling machines and tools is carried out, so that the geological forecast requirement of the construction of the ultra-long tunnel of the tibetan railway is met, the construction safety is ensured, and the construction efficiency is improved. The rope coring drilling technology has the advantages of high drilling efficiency, small disturbance degree on samples and the like, and is widely applied to the field of small-caliber geological exploration. However, the large-caliber long-distance near-horizontal exploration has the following main differences compared with the conventional geological exploration: conventional geological exploration typically has borehole diameters between 75mm and 150mm, with a near vertical borehole solution being the dominant borehole diameter, while large bore long distance horizontal exploration typically has borehole diameters between 300mm and 600mm, with a near horizontal borehole solution being employed. The increase of the diameter of the drill hole obviously increases the whole weight (the sum of the weight of the drill tool and the weight of the obtained core sample) of the drilling tool while increasing the number of the drilled core samples, the conventional geological exploration drilling tool usually adopts a spearhead structure to be matched with a fishing hook component in a fisher to realize the fishing and lifting of a drilling tool assembly, and the spearhead is a stress concentration point in the operation process. As the overall quality of the drill tool increases significantly, the risk of spearhead strength failure increases and the chances of potential drilling accidents increase. Compared with the vertical drilling scheme, the drilling tool is influenced by the gravity action when the nearly horizontal drilling is adopted, and the eccentric wear phenomenon of the drilling tool is easy to occur in the conveying process, so that the running resistance is increased. In addition, when the drilling tool is delivered for operation, the elastic clamping plate of the conventional drilling tool slides downwards against the inner surface of the drill rod under the action of spring force, and the abnormal abrasion is serious. In order to improve the positioning reliability of the elastic clamping plate, the spring stiffness is often required to be improved, meanwhile, the abrasion degree of the elastic clamping plate is increased, and the technical contradiction is more prominent in the process of delivering the deep hole. In fishing operation, the conventional wire line core drill usually depends on the retraction jack connected with the spearhead to move a certain distance along the axial direction, so as to realize the retraction of the ejection jack. The card receiving mode requires that enough movement clearance must be provided between the bullet card board and the bullet card stopper in the outer pipe assembly, and the bullet card board and the bullet card stopper are easy to be pushed up when drilling in a complex stratum, so that the card cannot be received smoothly, and the risk of the drill clamping accident is increased. At present, the rope core drilling tool for large-caliber near-horizontal engineering exploration mainly aims at enlarging the structure size on the premise of continuing using a conventional structure form, the advantages of a rope core drilling technology in large-caliber horizontal exploration are not fully exerted, and the working reliability and the stability are reduced.

In the rope coring drilling tool suitable for large-caliber horizontal engineering geological exploration, the upper end of the pushing mechanism is in threaded connection with the central hole of the joint, and the pushing mechanism is provided with the locking nut.
In the rope coring drilling tool suitable for large-caliber horizontal engineering geological exploration, the lower part of the clamping jaw is provided with a through hole, the roller is arranged in the through hole through an elastic cylindrical pin, and the elastic cylindrical pin is parallel to the cylindrical pin.

In the rope core drill suitable for large-caliber horizontal engineering geological exploration, the capturing mechanism is of a bell jar type structure, and the bottom of the capturing mechanism can be meshed with the top of the clamping jaw.
Compared with the prior art, the invention has the beneficial effects that:
1) when the fishing and lifting operation is carried out, the total weight of the drilling tool is jointly borne by the plurality of claws in the elastic clamp assembly, so that the stress load of a single claw is reduced; compared with a spearhead structure form, the invention can avoid the risk of spearhead strength failure caused by overlarge load and improve the reliability of the operation process.
2) The clamping jaw has the functions of positioning the spearhead and the elastic clamping plate of the conventional drilling tool, and can reduce the number of parts of a drilling tool assembly, so that the structure is simpler and more compact. In the horizontal throwing process, the roller at the lower part of the clamping jaw is in contact with the wall of the drill rod, so that the centering effect is achieved, the running resistance of the drilling tool is reduced, and the eccentric wear of the drilling tool caused by the gravity is reduced; the clamping jaws in the elastic clamp assembly can be in a folded state when horizontally delivered, so that the phenomenon of excessive abrasion in the delivery process is avoided, and the service life is long.
3) In the process of fishing, the catching mechanism of the fisher is used for forcing the clamping jaws to contract radially, compared with a mode that the conventional drilling tool realizes the contraction of the elastic clamping plate by moving the clamping cylinder for a certain distance axially, the contraction performance of the fishing tool is quicker and more reliable, the risk that the conventional drilling tool cannot normally fish due to the fact that the movement clearance between the elastic clamping plate and the elastic clamping stopper is lost when the conventional drilling tool drills in a complex stratum can be avoided, the reliability is high, and the fishing tool is convenient to operate. In addition, the water passing annular area of the water path system is increased, and the overall water passing performance of the drilling tool is improved.
