Description
Technical field
The present invention relates to drilling tool fishing operation field, be specifically related to a kind of slide block type fisher.
Background technology
During some bridges, highway construction, need at ground or water-bed construction drill, special according to different geology
Levying and Structural strength calls, the degree of depth of boring is had nothing in common with each other, and utilizes the drilling tool on rig to implement drilling operation, be drilled with
Steel reinforcement cage is transferred in boring, and then casting concrete is formed for cast-in-situ bored pile.Above-mentioned rig implement drilling operation time, rig
Setting up on the ground, the lower end of the rotating shaft of rig is connected with drilling tool, and rig starts gearing drilling tool and rotates, thus implements boring behaviour
Make, the bore diameter being drilled with is the most identical with the diameter of drilling tool, but above-mentioned rig is during being drilled with, drilling tool often due to
Geological Reasons amplitude of fluctuation is relatively big, causes the accident that drilling tool comes off with rig, if salvaging not in time, certainly will delay whole work
Phase, affect whole project progress, in prior art, mostly utilize lifting rope and suspension hook to implement the salvaging to drilling tool, however above-mentioned
In salvaging mode, when drilling tool is drilled with the deeper position of below ground, above-mentioned suspension hook is utilized not only to be difficult to the mode of lifting rope
Determining the position of drilling tool, and suspension hook is during upper lifting, drilling tool is easy to deflection, thus causes drilling tool cannot pick up at all
Phenomenon, thus need repeatedly to lift operation, until righting drilling tool, drilling tool, above-mentioned salvaging mode difficulty pole can be pulled out
Greatly, the longest.
Summary of the invention
It is an object of the invention to: a kind of slide block type fisher is provided, it is possible to the drill bit with central canal is entered by convenient enforcement
Row is salvaged, and improves and salvages efficiency.
For achieving the above object, the technical solution used in the present invention is:
Slide block type fisher, including fisher body, fisher body is overall in circular cone shape structure, on fisher body
Being provided with directive slide track, directive slide track is laid along fisher body generatrix direction, and directive slide track is along fisher body circumference
Direction is provided with multiple, and directive slide track is provided with guide runner, and described guide runner lateral surface is used for and drilling tool to be salvaged
Central canal inwall against or separate.
The present invention there is also following characteristics:
It is provided with through hole on described guide runner, in described through hole, is provided with alloy dop, one end of described alloy dop
With directive slide track constitute against or separate cooperation, the other end of alloy dop stretch out through hole and with in the central canal of drilling tool to be salvaged
Wall against or separate.
Described alloy dop is rod-like structure, and described through hole is positioned at the aperture of guide runner side and is provided with limiting stand
Rank, alloy dop are provided with position limiting convex ring and constitute against with limited step or separate cooperation.
One end of described fisher body is extended guide section, and described guide section is truncated cone structure, guide section
Large scale end be connected with the large scale end of fisher body, the other end of described fisher body be provided with and elevating mechanism even
The connection bar segment connect.
Length direction along directive slide track is arranged at intervals with multiple installing hole, and described installing hole is counter sink and is provided with peace
Dress bolt, the rod end installing bolt is connected with fisher body.
Described fisher body is provided with the section of threadeding, described threaded section and guide section with the connection end of guide section
On screwed hole constitute threaded cooperation.
The center of described guide section and fisher body offers first, second through hole.
Compared with prior art, the technique effect that the present invention possesses is: in actual fishing operation, utilizes elevating mechanism to incite somebody to action
Above-mentioned fisher explores downward to down-hole, and fisher body stretches in the central canal of drilling tool to be salvaged, during fisher test,
Guide runner slides on directive slide track, owing to fisher body is circular cone shape, the diameter that guide runner lateral surface encloses by
Gradual change is little, so enter salvage drilling tool central canal in, above-mentioned guide runner under the effect of self gravitation along directive slide track
Move down, so that the lateral surface of guide runner and the central canal inwall salvaging drilling tool recline, along with the upper shifting of fisher, boring
Under tool action of gravity, so that the lateral surface of guide runner and the central canal inwall salvaging drilling tool paste tighter and tighter, and then extremely
Conveniently the drilling tool with central canal is salvaged.

Detailed description of the invention
In conjunction with Fig. 1 to Fig. 4, the present invention is further described:
Slide block type fisher, including fisher body 10, fisher body 10 entirety is circular cone shape structure, and fisher is originally
Be provided with directive slide track 20 on body 10, directive slide track 20 along fisher body 10 generatrix direction lay, directive slide track 20 along
Fisher body 10 circumferential direction is provided with multiple, directive slide track 20 is provided with guide runner 30, outside described guide runner 30
Side for the central canal inwall of drilling tool to be salvaged against or separate.
Shown in Fig. 4, in actual fishing operation, utilize elevating mechanism that above-mentioned fisher is explored downward to down-hole, salvage
Device body 10 stretches in the central canal A of drilling tool to be salvaged, and during fisher test, guide runner 30 is at directive slide track 20
Upper slip, owing to fisher body is circular cone shape, the diameter that guide runner 30 lateral surface encloses tapers into, and then entrance is beaten
Dragging in the central canal A of drilling tool, above-mentioned guide runner 30 moves down along directive slide track 20 under the effect of self gravitation, so that
The lateral surface of guide runner 20 and the central canal A inwall salvaging drilling tool recline, along with the upper shifting of fisher, in drilling tool action of gravity
Under, so that the lateral surface of guide runner 30 and the central canal A inwall salvaging drilling tool paste tighter and tighter, and then extremely convenient will band
The drilling tool having central canal salvages.This fisher can effectively shorten the salvaging cycle, improves project progress.
Shown in Fig. 2 and Fig. 3, as the preferred version of the present invention, for improving guide runner 30 and wait to salvage further
The contact friction force of the central canal A of drilling tool, it is to avoid drilling tool comes off from fisher, described guide runner 30 is provided with through hole
31, it is provided with alloy dop 32 in described through hole 31, one end of described alloy dop 32 and directive slide track 20 constitute against or divide
From cooperation, the other end of alloy dop 32 stretch out through hole 31 and with the central canal A inwall of drilling tool to be salvaged against or separate；
In above-described embodiment, during reality is salvaged, guide runner 30, under self gravitation effect, falls to salvage
Device body 10 least significant end, above-mentioned alloy dop 32 and directive slide track 20 against so that alloy dop 32 stretches out through hole 31
And with salvage drilling tool central canal A inwall against, and then will salvage drilling tool clamping fastening, it is ensured that drilling tool is salvaged, on
Alloy dop 32 and through hole 31 clearance fit stated, during test, there is a certain amount of shrinking back in alloy dop 32, it is to avoid
Alloy dop 32 produces against interference with the central canal A upper end of drilling tool to be salvaged, and then guarantees the smooth test of alloy dop 32.
Further, shown in Fig. 2 and Fig. 3, for implementing the spacing of involutory gold card head 32, described alloy dop 32 is in bar
