Abstract
The utility model relates to a guide rod structure for a twisting machine. The guide rod structure comprises a bottom cover, wherein a guide rod is arranged in the bottom cover; the exterior of the guide rod is sleeved with a spring, and the exterior of the spring is sleeved with an outer sleeve; the bottom of the outer sleeve is connected with the bottom cover; the head part of the guide rod extends out of the top of the outer sleeve; a through hole is formed in the head part of the guide rod; a positioning pin is mounted in the through hole, and is fixed via a cotter pin. The guide rod structure is reasonable and compact, and convenient to manufacture and install; through arranging the spring on the guide rod in a sleeving way, a damping effect is achieved when the guide rod structure is in use, and under the action of the spring, a buffering role is played on the guide rod, so that the using safety is improved, and the service life of the guide rod is prolonged.
Description
Technical field
The utility model relates to twisting machine, especially a kind of twisting machine guide rod structure.
Background technology
Twisting machine is when the drilling of geological drilling, for a kind of machinery of unloading drilling rod.It can replace manpower unloading drilling rod, alleviates labor strength, improves lifting work efficiency.
Guide rod is one of vitals in twisting machine, and guide rod is installed between the main pincers and secondary pincers of twisting machine, and main clamper is in the top of guide rod, and secondary clamper is in the below of guide rod.
Guide rod of the prior art, adopts firmly and connects, fragile in its use procedure.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of twisting machine guide rod structure rational in infrastructure, thereby makes guide rod in use play the effect of damping, has increased safety and has extended application life.
The technical scheme that the utility model adopts is as follows:
A kind of twisting machine guide rod structure, comprise bottom, in described bottom, be provided with guide rod, the outer cover of described guide rod has spring, and the outside of described spring is nested with overcoat, and described jacket bottom is connected with bottom, described guide rod head stretches out in the top of overcoat, the head of described guide rod has through hole, and alignment pin is installed in described through hole, and described alignment pin is fixed by cottor pin.
Further improvement as technique scheme:
Between described jacket bottom and bottom, be threaded connection, on the inner peripheral surface of described bottom, be provided with internal thread, the bottom of described overcoat is provided with external screw thread;
On described bottom sidewall, have installing hole, also comprise the screw through installing hole, described bottom and overcoat pass through screw fastening.
The beneficial effects of the utility model are as follows:
The utility model is rational in infrastructure, compact, makes with easy for installation, by the effect of the spring that is nested with on guide rod, when it uses, played cushioning effect, under the effect of spring force, guide rod has the effect of buffering, improve safety in utilization, extended its application life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is explosive view of the present utility model.
Wherein: 1, cottor pin; 2, alignment pin; 3, guide rod; 4, overcoat; 5, screw; 6, bottom; 7, external screw thread; 8, spring; 9, through hole; 10, internal thread; 11, installing hole.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As depicted in figs. 1 and 2, the twisting machine guide rod structure of the present embodiment, comprise bottom 6, be provided with guide rod 3 in bottom 6, the outer cover of guide rod 3 has spring 8, the outside of spring 8 is nested with overcoat 4, overcoat 4 bottoms are connected with bottom 6, and guide rod 3 heads stretch out in the top of overcoat 4, and the head of guide rod 3 has through hole 9, the interior installation alignment pin 2 of through hole 9, alignment pin 2 is fixing by cottor pin 1.
Between overcoat 4 bottoms and bottom 6, be threaded connection, be provided with internal thread 10 on the inner peripheral surface of bottom 6, the bottom of overcoat 4 is provided with external screw thread 7.
On bottom 6 sidewalls, have installing hole 11, also comprise the screw 5 through installing hole 11, bottom 6 is fastening by screw 5 with overcoat 4.
In actual installation process, first guide rod 3 is installed in bottom 6, on guide rod 3, overlap upper spring 8, then there is the outside of the guide rod of spring 83 to be nested with overcoat 4 overlapping, overcoat 4 bottoms and bottom 6 are screwed by screw thread, guide rod 3 heads are the main clipper joint with twisting machine by alignment pin 2, the finally secondary clipper joint with twisting machine by bottom 6.Its simple installation, under the effect of spring 8, it has certain cushioning effect while using, and safety is good, long service life.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
