Following defect is enough deposited in the motion control that in existing single rotary double core barrel, control bullet clamp open and shrink: on the one hand, two play clamp and are contained in and are played in card holder by pin, because play clamp and be rotatable being contained in, play card holder and when open configuration, can stretch out the sidewall that plays card holder, therefore play a normally cylindrical structure of card holder, and be provided with long groove, playing clamp is contained in long groove, and can stretch out from long groove, in order to position playing the bottom of clamp, conventionally also need in playing card holder, bullet deck be set, playing deck is provided with and the groove that plays clamp bottom and coordinate, two play clamp when open configuration, be close to bullet card indoor, play deck by straight pin and bullet card holder, recovery tube connects, so, these component of bullet deck have been increased.
Summary of the invention
The applicant improves for above-mentioned shortcoming of the prior art, and a kind of motion control mechanism that plays clamp is provided, and it can effectively be controlled and play opening and contraction of clamp, and has save bullet deck, simplifies the structure.
Technical scheme of the present invention is as follows:
Play the motion control mechanism of clamp, comprise recovery tube, recovery tube top by elastic cylindrical pin one with drag for lance seat and be connected, drag for lance seat and be positioned at recovery tube, drag for lance seat below and be provided with bullet card holder, recovery tube is connected with bullet card holder by elastic cylindrical pin two, two play clamp and are arranged on rotationally and are played in card holder by bearing pin, and two play clamp and are positioned at the long groove that plays card holder, playing card holder is multidiameter structure, and the middle part external diameter that plays card holder is greater than the external diameter that plays card holder top and bottom, long groove is positioned on the described top that plays card holder, and long groove extends to the middle top surface that plays card holder, the described middle top surface that plays card holder is provided with the groove coordinating with the bottom that plays clamp, bearing pin is contained in the described top that plays card holder, the lower end that plays clamp is arranged on rotationally and is played in card holder by bearing pin, between the upper end of two bullet clamp, be connected with tension spring.
Its further technical scheme is:
The upper end in the outside of described bullet clamp is provided with positioning step.
Technique effect of the present invention:
The present invention controls bullet clamp by tension spring and opens, and shrinks by the symmetrical channels compressing bullet clamp on the recovery tube in up, thereby realizes the motion control that plays clamp; By the structure design to the multidiameter of bullet card holder, and the long through-hole that makes assembling play clamp extends to the larger middle part end face of external diameter that plays card holder, after bullet clamp are seated, the bottom that plays clamp is positioned at the detent playing on the middle part end face that the external diameter of card holder is larger, so save bullet deck of the prior art, simplified drilling tool structure; Further, upper end in the outside of described bullet clamp is provided with positioning step, when playing clamp, open and be close to bullet card when indoor, by coordinating with the catch arranging on bullet block head at positioning step, by playing clamp and the butt positioning action that plays block head upper stop piece, improve the connection reliability that plays block head and drilling tool outer tube, avoided the relatively rotating between block head and drill bit of being hit by a bullet of working, can effectively avoid playing the loosening and wearing and tearing of block head.
Accompanying drawing explanation
Fig. 1 is sectional structure schematic diagram of the present invention, in figure, also shows and drags for spearhead.
Fig. 2 is decomposition texture schematic diagram of the present invention, and the bullet card holder in figure is three-dimensional structure diagram, and straight pin is not shown.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1, Fig. 2, the present invention includes recovery tube 1, recovery tube 1 top by elastic cylindrical pin 1 with drag for lance seat 3 and be connected, drag for lance seat 3 and be positioned at recovery tube 1, drag for lance seat 3 tops by elastic cylindrical pin 39 with drag for spearhead 10 and be connected, spring base 11 is positioned at and drags in spearhead 10 by dragging for lance seat 3, dragging for spearhead spring 12 is located on spring base 11, drag for lance seat 3 belows and be provided with bullet card holder 4, recovery tube 1 is connected with bullet card holder 4 by elastic cylindrical pin 28, two play clamp 5 and are arranged on rotationally and are played in card holder 4 by bearing pin 6, and two play clamp 5 and are positioned at the long groove 41 that plays card holder 4, playing card holder 4 is multidiameter structure, and the middle part external diameter that plays card holder 4 is greater than the external diameter that plays card holder 4 tops and bottom, long groove 41 is positioned on the described top that plays card holder 4, and long groove 41 extends to the middle top surface that plays card holder 4, the described middle top surface that plays card holder 4 is provided with the groove coordinating with the bottom that plays clamp 5, bearing pin 6 is contained in the described top that plays card holder 4, the lower end that plays clamp 5 is arranged on rotationally and is played in card holder 4 by bearing pin 6, between the upper end of two bullet clamp 5, be connected with tension spring 7.
In practical application, after inner tube is transferred and is put in place, under the effect of tension spring 7, it is indoor that bullet clamp 5 strut and be close to bullet card, when the basket of drilling tool is filled after rock core, by dragging for lance device, enough firmly drag for spearhead 14, to on the inner tube device of whole drilling tool, carry, in the process of carrying in drilling tool inner tube, by elastic cylindrical pin 1, elastic cylindrical pin 28, elastic cylindrical pin 39, drive on recovery tube 1 and carry, recovery tube 1 symmetrical channels compressing bullet clamp 5 by himself in up process inwardly shrink, and bullet clamp 15 are contracted to and leave bullet card chamber, can take out inner tube and rock core.
