Abstract
The utility model relates to a wire line coring drill bit fisher which comprises a sleeve and a fishing shaft disposed in the sleeve. A pull rod connected with the fishing shaft in a threaded manner is disposed in the sleeve. An impact connector in clearance fit with pull rod is disposed on the pull rod. A weighing rod connected with the impact connector in a threaded manner is disposed on the impact connector. The fishing shaft is connected with the sleeve through a first screw. A longitudinal groove is formed in the wall of the sleeve. A second screw which can move in the longitudinal grove is disposed on the impact connector. By the structure, compared with the prior art, the wire line coring drill bit fisher has the advantages that when a fisher inner tube assembly meets resistance or during dry hole drilling, the impact connector is used for automatic releasing, releasing tubes required by common fishers can be avoided, time for throwing the releasing tubes is saved, effect is increased, and the wire line coring drill bit fisher is safe and reliable.
Description
Technical field
The utility model relates to a kind of core plugging notifying mechanism of rope core drilling of drilling with boring sample, concrete relates to a kind of core plugging notifying mechanism of rope core drilling fisher.
Background technology
Along with the fast development of China's economy, the demand of mineral resources is increased day by day.We just must find new mineral resources like this, and " 9 5～15 " country takes over and dropped into substantial contribution the resource of large-scale Resources Crisis Mines In China, for looking for ore deposit.New mineral resources major part is distributed in depths, stratum or bad ground.
Wire line coring drilling technology is applied to the existing history more than 30 years of production practices in China, because it has the advantages such as drilling efficiency is high, core recovery is high, labour intensity is low, is widely used.Now become the Main Means that China looks for ore deposit at present.At present conventionally be generally common core plugging notifying mechanism of rope core drilling, comprise drilling tool body, fisher, salvages inner tube assembly when fisher and is hampered or is creeping into dry hole, and while veering away inner tube assembly with fisher, fisher all needs to get back to earth's surface after de-card.Existing fisher adopts conventionally throws in the de-card of de-card pipe, not only waste time and energy, and reliability is poor.
Summary of the invention
Problem to be solved in the utility model is to propose a kind of deep borehole wire-line coring dart for above-mentioned prior art, and it is simple in structure, and cost of production is low, and de-card is easy, quick, safe and reliable.
The problem that the utility model is the above-mentioned proposition of solution is adopted solution to be: a kind of core plugging notifying mechanism of rope core drilling fisher, comprise sleeve and be located at the salvaging axle in sleeve, in sleeve, be provided with and the pull bar of salvaging male thread and being connected, pull bar is provided with the impact joint being connected with pull bar matched in clearance, impacting joint is provided with and the weighted lever that impacts joint screw thread and be connected, salvaging axle is connected with sleeve by screw one, in sleeve wall, offer cannelure, impact joint and be provided with the screw two that can move in cannelure.
In described sleeve wall, offer two parallel cannelures, between two cannelures, be provided with the transverse groove of two cannelures of UNICOM.
The utility model is owing to adopting said structure, and not only simple in structure, cost of production is low, and de-card is easy, quick, safe and reliable, and has improved and crept into work efficiency.During use:
1) when fisher inner tube assembly is hampered, can pass through rope winch tense wire rope, wire rope is by wire clips joint tension weighted lever, impact joint and pull bar, and then loosen wire rope, weighted lever is descending along pull bar together with impacting joint, impact joint and impact salvaging axle, effect lower sleeve at impulse inertia is deviate from descending from locking ball, cover recovery hook afterbody, recovery hook head is opened, discharge the spearhead that drags for of inner tube assembly, thereby fisher and inner tube assembly are departed from, with with the de-card of de-card pipe, compare, the method has been saved the time of throwing in de-card pipe, and more simple and safe reliable.
2) when creeping into dry hole, interior anhydrous because holing, directly throw in inner tube assembly, can damage drilling tool too soon because of falling speed, generally can adopt the fisher inner tube assembly that veers away.Now first the screw of salvaging axle is laid down, the screw that impacts joint is proceeded in the cannelure of sleeve.When inner tube assembly is delivered to outer pipe assembly position, the screw impacting on joint clashes into sleeve, sleeve is deviate from from locking ball descending, and fisher automatic trip card, carries back fisher.Compare with common fisher, saved the time of throwing in de-card pipe herein, improved effect, and safety and reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the K of Fig. 1 is to view.
The specific embodiment
Below in conjunction with by reference to the accompanying drawings the utility model being done to further detailed description.
As depicted in figs. 1 and 2, the utility model comprises sleeve 5 and is located at the salvaging axle 7 in sleeve 5, in sleeve 5, be provided with and the pull bar 4 of salvaging axle 7 and being threaded, pull bar 4 is provided with the impact joint 3 being connected with pull bar 4 matched in clearance, the matched in clearance of impacting joint and pull bar makes the two can relative motion, impacts joint 3 and is provided with and the weighted lever 1 that impacts joint 3 and be threaded, and salvages axle 7 and is connected with sleeve 5 by screw 6, in sleeve wall, offer cannelure A, B, C and transverse groove D, referring to accompanying drawing 2.Impact joint 3 and be provided with the screw 2 that can move in cannelure.The utility model sleeve 5 is socketed in and impacts joint 3 and salvage above axle 7, with locking ball 8 location.When adopting the fisher inner tube assembly that veers away, now the screw 6 of salvaging axle 7 (in B groove) is laid down, will impact the screw 2 of joint 3 from the cannelure A of sleeve 5, in transverse groove D screw-in cannelure C.When inner tube assembly is delivered to outer pipe assembly position, inner and outer pipes assembly stops descending, impacts joint 3 and along pull bar 4, continues descending, the screw 2 impacting on joint 3 is descending together, strike the bottom of short pod C on sleeve 5, force sleeve 5 compressing locking balls, steel ball Compress Spring 9, sleeve 5 is deviate from descending from locking ball, cover recovery hook 10 afterbodys, and recovery hook 10 heads are opened, discharge the spearhead that drags for of inner tube assembly, fisher automatic trip card, carries back fisher.
All the other structures of the present utility model are identical with the structure of existing cord coring drill, do not repeat them here.
