Abstract
The invention relates to a cord core drilling tool for a tunnel subhorizontal hole, capable of improving the applicability of the cord core drilling tool in the construction of the tunnel subhorizontal hole. A cord core drilling tool product special for a subhorizontal tunnel is absent in the market at present, only individual user unit for constructing large-angle declined holes improves a ground cord core drilling tool for reluctant use, and the advantages of the cord core drilling technology are not brought into play. By designing a lug boss for fishing a spear and a composite positioning mechanism for opening a clamp and positioning a core shaft, the cord core drilling tool effectively prevents the single-sided clamping in the process of drilling the subhorizontal hole. An inner tube assembly has a sectional structure, the rapid connection and disconnection of an inner tube are realized, and the problem between shorter stroke of the drill and longer inner tube is solved. A mud pump pumps the inner tube assembly and a hydrostatic bailer for providing power for constructing the subhorizontal hole. The cord core drilling tool effectively solves the problem of the applicability of the cord core drilling tool during the construction of the subhorizontal hole, and improves the working efficiency of drilling operation.
Description
Technical field
The present invention relates to a kind of cord core drilling tool for tunnel subhorizontal hole.
Background technology
The tunnel exploration can be saved a large amount of probing workloads with respect to the earth's surface exploration, application at the mineral resources exploration development field is also comparatively general, and the wire line coring drilling technology has obtained widely concern with advantages such as its rate height of coring, drilling efficiency are high, geological effect is good.The tunnel exploration often needs construction to creep into lower inclined hole, near-horizontal hole along mineral deposit layer band except the nearly upright opening of constructing, or even upper uphole.During surface drilling, the space is unrestricted, the rig stroke can be done more greatly, the length of corresponding drilling tool inner tube assembly also can be grown, and the drilling tool inner tube length of standard is 3000mm, and the long stroke of rig can guarantee disposable proposition inner tube assembly, but in the tunnel, creep into, the stroke of rig is partially short, and length of tube is long in the cord coring drill of ground drilling, uses inconvenience in the tunnel; When construction, adopting near upright opening, can rely on free gravity to transfer inner tube assembly and fisher, and near-horizontal hole when advancing, can't be realized by hole drill the free releasing of inner tube assembly and fisher with facing upward in the tunnel; The mechanism that the common employing of the bullet care positioner of cord coring drill leans on the tension force of tension spring that the bullet card is opened, it is rear fixing to realize that inner tube assembly puts in place, prevent the inner tube vibration that makes progress, the location was reliable when nearly upright opening crept in this mechanism, but when near-horizontal hole creeps into, be subjected to the impact of Action of Gravity Field own, produce easily monolateral phenomenon of being blocked, positioning function lost efficacy.The cord coring drill product that does not have in the market the special use of nearly adit, only there is the Subscriber Unit of inclined hole under other construction wide-angle that inadequate use is improved with cord coring drill in ground, do not given play to the advantage of Trend of Wireline Core Drilling Techniques, result of use is poor.

The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
A kind of cord core drilling tool for tunnel subhorizontal hole involved in the present invention is the technological improvement of carrying out with the basis of cord coring drill at existing nearly upright opening.
At first, the present invention is designed compound detent mechanism in inner tube assembly, the bullet fastening position mechanism and the axle detent mechanism that namely are comprised of axle 5, cushion block 6, spring 7, tension spring 8, bullet card 9, guide 10 and bullet deck 11.Tension spring 8 is connected with the bullet card by guide 10 connections, and the gross thickness of bullet card both wings equates with the notch width that plays deck 11, utilizes elastic cylindrical pin that tension spring 8 and bullet card 9 are connected on the bullet deck 11.When inner tube assembly was transferred in drill string, tension spring 8 made bullet card 9 outside opened with certain angle, and along drill string inwall down sliding, in case arrive proper site, bullet card 9 continues outwards to open under the effect of tension spring 8, and its both wings are attached on the drill string inwall.Axle 5 is connected to by elastic cylindrical pin and drags on the lance seat 1, and cushion block 6 is connected with recovery tube and is formed dead connection by pin, between axle 5 and the cushion block 6 spring 7 is set, and axle 5 is axially arranged with slippage slot.When bullet card 9 opened under the effect of tension spring 8 fully, axle 5 can enter under the effect of spring 7 in the bullet card cavity.Drilling tool is non-perpendicular when creeping into, inner and outer pipe and drag for spearhead 1 and be easy to eccentric phenomena occur because of non-perpendicular transferring, and so compound locate mode has effectively guaranteed inner and outer pipe and the concentricity of dragging for spearhead 1, prevents from transferring the monolateral stuck phenomenon that occurs in the process.The present invention also is provided with locating convex block at the outer round surface that drags for spearhead 1, and effect also is to prevent when lateral aperture creeps into, and drags for spearhead 1 and the eccentric imagination occurs under the self gravitation effect, can not enter smoothly fisher during salvaging, improves the reliability of transferring and salvaging.
Secondly, inner tube assembly of the present invention adopts segmentation structure, and spring housing 19, spring 20, sliding lock set 21, bearing pin 22 and connecting axle 23 namely are set at the middle part of inner tube assembly, forms the quick release mechanism of inner tube assembly.Connecting axle 23 links to each other by bearing pin 22 with spring housing 19, and bearing pin 22 cylindricals are provided with sliding lock set 21, is provided with spring 20 between sliding lock set 21 and the spring housing 19, makes inner tube assembly do as a whole use; When salvaging inner tube, inner tube assembly is proposed to expose the aperture to connecting axle 23 first, unclamp sliding lock set 21, get bearing pin 22, just inner tube assembly can be divided into up and down two parts, propose respectively.The long stroke of rig can guarantee disposable proposition inner tube assembly, but creeps in the tunnel, and the stroke of rig is partially short, and length of tube is long in the cord coring drill of ground drilling, uses inconvenience in the tunnel.And segmented inner tube assembly of the present invention design, the contradiction between having solved effectively that the stroke of rig is partially short and growing as far as possible with interior length of tube.
In addition, the present invention adopts slush pump pumping inner tube assembly and waterpower fisher.During the pumping inner tube assembly, steel wire cable 27 is passed logical cable formula water swivel, steel wire cable 27 is connected on the wire clips cover 28 of flume conveyer, the sealing function lower nip flume conveyer of the press water of slush pump connecting axle 30 on flume conveyer, thereby the propelling inner tube assembly, connecting axle 30 adopts nylon material, is convenient to the conveying of waterpower, blocking cap 32 Front-end Design are spherical, are reduced in jammed probability in the drill string hole; When salvaging inner tube assembly, the waterpower fisher drags for spearhead 1 by recovery hook 35 at the bottom of transferring to the hole under the slush pump pressure water action, carry inner tube assembly.During the nearly vertical operation of drilling tool, inner tube assembly and fisher can rely on self gravitation to transfer at the bottom of the hole, but under the tunnel of nearly horizontal operation angle condition, inner tube assembly and fisher arrive assigned address by executing power outward, the present invention utilizes the mode of slush pump pumping, effectively improve lowering velocity, improved the applicability of drilling tool.
