Description
Technical field
This utility model relates to geological prospecting apparatus technical field, refers specifically to a kind of drilling core pipe washer.
Background technology
In geological drilling works, technical staff judges stratum mainly through core form, and taking core is critical work in engineering drilling. Taking of major part stratum (cohesive soil, silt, layer of sand) core is to be crept into by rig machinery, suitably pressurizes in process, and drilling rod transmission pressure, to bottom core barrel, is taked core with static pressure method, is then lifted out earth's surface. During coring, access water pipe at core barrel head, pressurize with water pump, produce horizontal thrust by water pressure, extrude core, core is extruded from the other end. When practical operation, probing coring is repeatedly repeated due to core barrel, core barrel inwall generally remains cohesive soil, silt, sand etc., if core barrel inwall does not get effective washing, the cohesive soil that then remains, silt, sand etc. easily block core barrel, the influence technique personnel judgement to stratigraphic categories. The core remaining in core barrel inwall easily blocks core barrel, also can affect the follow-up core recovery creeping into round trip, has a strong impact on probing work quality and efficiency.
At present, the complete drilling equipment of domestic sale and related accessory, all it is configured without effective core barrel cleaning means. Cleaning method conventional in prior art is to be sling by drilling core pipe with steel wire rope on rig, by beaing, shake the mode of core barrel outer wall, residual core in pipe is made to drop voluntarily, also the thing such as useful drilling rod discloses the mode taken back and forth, What is more, and direct hands puts in draw takes, abnormally dangerous, and operator find to adopt conventional mechanical shock, beat, draw and the means such as take and be difficult to the core of fully erased core barrel inwall, cause inefficiency, there is potential safety hazard. And of long duration, can be more long-pending more thick in pipe.The washer of rock core in drilling core pipe can be effectively removed, it appears particularly necessary therefore it provides a kind of.
Utility model content
Technical problem to be solved in the utility model is the present situation for prior art, it is provided that a kind of simple and reasonable, easy to use, and can be effectively improved the drilling core pipe washer of work efficiency and cleannes.
The technical scheme that the above-mentioned technical problem of this utility model solution adopts is: a kind of drilling core pipe washer, it is characterized in that: include cleaning head and connecting rod, described cleaning head is shaped to cylindrical shape, the front end of described cleaning head is provided with the removing cutter extended forward, this removing cutter in the form of a ring and external diameter less than the internal diameter of cleaning head, the rear end of described cleaning head is provided with the connecting plate of a lateral arrangement, and one end of described connecting rod is connected on this connecting plate.
As further improvement of the utility model, the front end of described removing cutter has blade, and the rear end of described removing cutter is welded on cleaning head by multiple spaced apart connection sheets, and adjacent two connect formation between sheet supplies the spray orifice of current traverse. Adopt such structure, from the current with certain hydraulic pressure of drilling core pipe other end inflow when running into removing cutter, current accelerate owing to internal diameter diminishes suddenly and from the outside scattering of spray orifice, thus the inwall of drilling core pipe is washed away, coordinate remove terminal knife edge before cutter on drilling core inside pipe wall core strike off effect, clean out thus will be attached to core on core barrel inwall fast and effectively.
Further, being provided with near connecting the rounded tabs that sheet is arranged in the inner chamber of described cleaning head, the external diameter of this catch is (1/3)��(1/2) of described cleaning head internal diameter. Current are played barrier effect by arranging of above-mentioned catch, and the current being blocked then can spray from spray orifice with bigger power towards periphery, thus the stronger core removed on drilling core inside pipe wall.
For the ease of connecting, the connection strap that described catch is arranged in catch periphery by interval is welded on the inwall of cleaning head.
In above-mentioned each scheme, described connecting plate is arranged at the middle part of cleaning head rear end and the rear port of cleaning head is divided into two equal-sized semicircles. Adopt this spline structure, it is simple to current flow out from two semicircular ports.
As preferably, the lateral surface of described connecting plate being provided with outward extending threaded post, correspondence, the front end of described connecting rod has the screwed hole being connected with above-mentioned threaded post. Described connecting rod be at least two joint and dismountable type link together; Preferably, it is threaded togather between two described connecting rods. Adopt said structure, it is possible to regulate the length of connecting rod according to the length requirement of basket.
Preferably, described drilling core pipe washer also includes water pump and water pipe, and one end of described water pipe is connected with water source, and the other end of described water pipe is connected with the water inlet end of drilling core pipe, and described water pump is for providing power for the current in water pipe.
Compared with prior art, the utility model has the advantage of: this utility model provides a kind of structure being exclusively used in and cleaning drilling core pipe, this is simple and reasonable, during use, the current with certain pressure are accessed in one end of drilling core pipe, flow out from the other end of drilling core pipe after core on current scour drilling core inside pipe wall, in this process, cleaning head is stretched in drilling core from one end that current flow out by hand-held connecting rod, core on drilling core inside pipe wall can be struck off by the cutter of removing of cleaning head front end, and, there are the current of certain pressure when running into cleaning cutter, owing to the internal diameter of cleaning cutter is less than cleaning head, water velocity can increase and part disperses to wash away on drilling core inside pipe wall, thus quickly, effectively remove the core of attachment on drilling core inside pipe wall, it is effectively increased work efficiency and the cleannes of drilling core pipe, extremely easy to use.
