Abstract
The utility model relates to a novel clamping-removing pipe structure which comprises a pipe body. An opening is formed in the outer periphery of the pipe body. One end of the opening is arranged at the 1/4 portion of the outer diameter of the pipe body, the other end of the opening is arranged at the 2/4 portion of the outer diameter of the pipe body, and accordingly the opening is communicated along the outer periphery of the pipe body from one end to the other end of the pipe body to form an arc shape. The novel clamping-removing pipe structure is simple and easy to manufacture, the arc opening effectively limits separation of a steel wire rope and the pipe body, potential safety hazards are effectively removed, and safety is improved.
Description
Technical field
The utility model relates to geological drilling field, relates in particular to a kind of novel de-card tubular structure.
Background technology
Back off structure is the mechanism that wire line coring fisher and the inner tube assembly being dragged for are thrown off in hole.Its structure is generally comprised of de-card pipe and impact bar, and the body of existing de-card pipe all arranges horizontal opening at present, and this horizontal opening structure easily makes wire rope deviate from de-card pipe, thereby causes the landing of de-card pipe to cause potential safety hazard.
Utility model content
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of novel de-card tubular structure is provided, and has effectively avoided wire rope and has taken off the separation of card pipe, has eliminated potential safety hazard.
The technical scheme that the utility model adopts is as follows:
A kind of novel de-card tubular structure, comprises body, in the periphery of body, opening is set, one end of opening is arranged on 1/4 place of body external diameter, the other end of opening is arranged on 2/4 place of body external diameter, makes the periphery of opening along body, and is communicated with and forms arc from one end to the other end of body.
Its further technical scheme is:
The radian of opening is 72 ° ± 1 °.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, manufacture easy, by 1/4 place opening being arranged on to body one end external diameter, at 2/4 place of body other end external diameter, opening is also set simultaneously, after this open communication, form arc opening, arc opening has effectively limited the disengaging of wire rope and body, has effectively eliminated potential safety hazard, has improved safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the utility model comprises body 1, in the periphery of body 1, opening 2 is set, one end of opening 2 is arranged on 1/4 place of body 1 external diameter, the other end of described opening 2 is arranged on 2/4 place of body 1 external diameter, make the periphery of opening 2 along described body 1, and be communicated with and form arc to the other end from one end of body 1, the radian of opening 2 is 72 ° ± 1 °.
The utility model is simple in structure, manufacture easy, by 1/4 place opening being arranged on to body one end external diameter, at 2/4 place of body other end external diameter, opening is also set, after this open communication, forms arc opening, arc opening has effectively limited the disengaging of wire rope and body simultaneously, even if one end of wire rope detaches body 1 in the course of the work, thereby its other end must be separated by the restriction of inboard wall of tube body from opening 2, has effectively eliminated potential safety hazard, has improved safety.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to basic structure of the present utility model in the situation that, the utility model can be done any type of modification.
