Abstract
The utility model relates to one and unloads effective guide rod structure, comprise the guide rod be placed in overcoat, the spring being placed on guide rod outer wall is provided with between overcoat and guide rod, the lower end of overcoat is connected with bottom spiral, the two ends up and down of described spring abut with the upper and lower side of overcoat respectively, the lower end of described overcoat is fixed with latch, the lower surface of latch abuts with bottom upper surface, latch is with the arcuate structure identical with outer casing outer wall, with outer screw on latch, the sidewall of overcoat is with the inner bolt hole corresponding with outer screw, in outer screw, screw has lock-screw, described lock-screw runs through the center that described inner bolt hole puts in described spring.Of the present utility model rational in infrastructure, compact, manufacture and installation is convenient, is nested with spring, plays good shock absorbing effect on guide rod; Latch structure is set, the axially-movable of restricted internal spring and rotary motion, reduces wearing and tearing, reduce noise, improve safety in utilization, extend its application life.
Description
Technical field
The utility model relates to geological prospecting apparatus field, particularly relates to a kind of guide rod structure unloading pipe machine.
Background technology
Unloading pipe machine is when the drilling of geological drilling, for the one machinery of unloading drilling rod.It can replace manpower unloading drilling rod, alleviates labor strength, improves lifting work efficiency.Guide rod unloads one of vitals in pipe machine, and guide rod is installed between the main pincers that unload pipe machine and secondary pincers, 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 Hard link, lacks Cushioning Design, easily damage because torsion is excessive and axial compression is excessive in its use procedure.
Had the guide rod setting up spring at present, solved Hard link Problems existing, but the employing of its spring is directly nested with mode, spring easily rotates on guide rod, and when guide rod uses, wearing and tearing are comparatively large, and noise is larger; Overcoat in guide rod and easily loosening due to long-time rotary motion between bottom.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of and rational in infrastructure unloads effective guide rod structure, thus make guide rod in use play the effect of damping, add safety and extend application life.
The technical scheme that the utility model adopts is as follows:
One unloads effective guide rod structure, comprise the guide rod be placed in overcoat, the spring being placed on guide rod outer wall is provided with between overcoat and guide rod, the lower end of overcoat is connected with bottom spiral, the two ends up and down of described spring abut with the upper and lower side of overcoat respectively, the lower end of described overcoat is fixed with latch, the lower surface of latch abuts with bottom upper surface, latch is with the arcuate structure identical with outer casing outer wall, with outer screw on latch, the sidewall of overcoat is with the inner bolt hole corresponding with outer screw, in outer screw, screw has lock-screw, described lock-screw runs through the center that described inner bolt hole puts in described spring.
The beneficial effects of the utility model are as follows:
Of the present utility model rational in infrastructure, compact, manufacture and installation is convenient, is nested with spring, plays good shock absorbing effect on guide rod; Latch structure is set, the axially-movable of restricted internal spring and rotary motion, reduces wearing and tearing, reduce noise; Latch and bottom near, increase bottom and the axial force of outer inner room, prevent spiral connection from delivering to, improve safety in utilization, extend 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, guide rod; 2, overcoat; 21, inner bolt hole; 3, latch; 31, outer screw; 4, bottom; 5, spring.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1 and Figure 2, the present embodiment unload effective guide rod structure, comprise the guide rod 1 be placed in overcoat 2, be provided with the spring 5 being placed on guide rod 1 outer wall between overcoat 2 and guide rod 1, the lower end of overcoat 2 is connected with bottom 4 spiral, and the two ends up and down of spring 5 abut with the upper and lower side of overcoat 2 respectively, the lower end of overcoat 2 is fixed with latch 3, the lower surface of latch 3 abuts with bottom 4 upper surface, latch 3 and bottom 4 near, prevent bottom 4 and overcoat 2 spirals to be connected loosening; Latch 3 is with the arcuate structure identical with overcoat 2 outer wall, with outer screw 31 on latch 3, the sidewall of overcoat 2 is with the inner bolt hole 21 corresponding with outer screw 31, in outer screw 31, screw has lock-screw, lock-screw runs through the center that inner bolt hole 21 puts in spring 5, namely lock-screw runs through the side of spring 5, the axially-movable of restraining spring 5 and rotary motion.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
