Description of drawings
The structural representation of a kind of drilling tool when first state that Fig. 1 is provided for the utility model embodiment;
The plan structure sketch map that Fig. 2 is a kind of drilling tool of providing of embodiment when first state for the utility model;
The structural representation of a kind of drilling tool when second state that Fig. 3 is provided for the utility model embodiment;
The plan structure figure of a kind of drilling tool when second state that Fig. 4 is provided for the utility model embodiment.
The specific embodiment
In order to make those skilled in the art understand the technical scheme of the utility model better, the utility model is done further to specify below in conjunction with accompanying drawing and specific embodiment.Should be pointed out that description and the description order to concrete structure only is the explanation to specific embodiment in this part, should not be regarded as that the protection domain of the utility model is had any restriction.
Please refer to Fig. 1 to Fig. 4; Wherein, The structural representation of a kind of drilling tool when first state that Fig. 1 is provided for the utility model embodiment; The plan structure sketch map that Fig. 2 is a kind of drilling tool of providing of embodiment when first state for the utility model, the structural representation of a kind of drilling tool when second state that Fig. 3 is provided for the utility model embodiment, the plan structure figure of a kind of drilling tool when second state that Fig. 4 is provided for the utility model embodiment; Combine Fig. 1 to Fig. 4 that a kind of drilling tool that the utility model embodiment is provided is described in detail below simultaneously.
As shown in the figure; This drilling tool comprises brill tube 1, and holder bar axial trough 3 is welded in (or through other fixed connection modes) and bores on the bottom of 1 inwall, and holder bar 2 is hinged with holder bar axial trough 3 through bearing pin; The both sides camber shape of holder bar; The number of holder bar 2 and corresponding with it holder bar axial trough is eight, and per four is one group, and every group is distributed on respectively and bores tube 1 inwall up and down on two circumferential plane; Shown in Fig. 1 or 2, holder bar 2 is attached to and bores on tube 1 inwall (first state), and shown in Fig. 3 or 4, holder bar 2 can rotate 90 ° of expansion (second state) under the restriction of holder bar axial trough 3; One end of holder bar 2 has groove;
In the course of the work, when drilling tool just changeed drilling depth, the holder bar can all be attached to and bore on tube 1 inwall, did not influence the cobble material and got in the brill tube 1; By the time the cobble material gets into and bores after the tube, makes the drilling tool counter-rotating, because an end of holder bar 2 has groove; At this moment, the groove place can clamp-on the assorted soil of rubble, and holder bar 1 can rotate around holder bar axial trough 3; So the groove place of holder bar 2 one ends can receive reaction force under the effect of the assorted soil of rubble, holder bar 2 also can launch up to 90 degree around holder bar axial trough 3 under the effect of reaction force; Promote and bore tube 1, get into the greater particle size cobble that bores in the tube 1 and hold, can be removed outside the hole with boring tube 1 by the holder bar 2 that bores tube 1 bottom.
Need to prove, in the foregoing description, adopt holder bar 1, in other embodiments, can also adopt tabular or bar-shaped holder part, only otherwise influencing its function gets final product as the holder part.
Need to prove, in the foregoing description, use two-layer eight holder bars respectively; Can reach and fish for effect preferably, in other embodiments, can also adopt one deck or the holder bar more than three layers; Every layer holder bar number also is not limited to four; For example, can for one (this kind situation is suitable for having the stratum of big boulder), two, three or more than five, its arrangement mode also not necessarily is limited as and is uniformly distributed with.
Need to prove that in the foregoing description, the maximum angle that the holder bar asks the bar axial trough to rotate relatively is 90 °, can reach and fish for effect preferably, but in other embodiments, this angle can also be other the arbitrary values within 60 ° to 120 °.
A kind of drilling tool that the utility model embodiment provides, through bore be provided with on the tube inwall bottom two-layer eight holder bars and with these eight the corresponding holder bar axial troughs of holder bar, when drilling tool is just changeing when creeping into; The holder bar is in first state, all is attached to bore on the tube inwall, does not influence the cobble material and gets into the brill tube; After the cobble material is packed the brill tube into, make the drilling tool counter-rotating, the holder bar is in second state; The holder bar asks the bar axial trough to turn an angle relatively, and an end of holder bar stretches into and bores in the tube, and the cobble material is held; Promote the brill tube this moment and shift out outside the hole, make the holder bar get back to first state, cobble is released; This drilling tool structure is simple, can effectively solve drilling tool creeps into difficulty or is difficult to fish for the greater particle size cobble on the stratum with greater particle size cobble problem, has improved greatly and has crept into quality and drilling efficiency.
