Abstract
The utility model relates to a clamping mechanism for a twisting machine. The clamping mechanism comprises a toothed casing, wherein the toothed casing is meshed with a gear driving the toothed casing to rotate for rotation; slope plates are mounted at intervals on the inner circumferential surface of the toothed casing; a fixing plate is mounted in the middle of the toothed casing, and a hole is formed in the middle part of the fixing plate; a pair of slips for clamping a pipe are mounted at the lower part of the fixing plate; the outer ends of the slips are fixedly connected with rolling wheels respectively. The clamping mechanism for the twisting machine is compact and reasonable in structure and convenient to operate; under the action of the slope plates, the rolling wheels are controlled to move inwards, so as to drive the slips to clamp the pipe, the using reliability of the clamping mechanism is good, and the working efficiency is high.
Description
Technical field
The utility model relates to twisting machine, especially a kind of twisting machine clamp mechanism.
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.
Clamp mechanism is one of twisting machine critical component, screwed pipe upper buckled or lower button need to be by clamp mechanism by tube grip, clamp mechanism of the prior art, its dependability is poor, upper buckle or during lower button that completes pipe, pipe can followed and rotated, thereby affect on pipe, buckles and lower work of buckleing, and affects operating efficiency.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of twisting machine clamp mechanism rational in infrastructure, thereby improves its dependability, increases work efficiency.
The technical scheme that the utility model adopts is as follows:
A twisting machine clamp mechanism, comprises band tooth shell, describedly with tooth shell, rotates with driving the gear engagement of its rotation, describedly with interval on the inner peripheral surface of tooth shell, ramp is installed; The middle part being positioned at tooth shell is provided with fixed head, described fixed head middle part perforate, and the bottom that is positioned at fixed head is provided with a pair of slips of clamping tube, and the outer end of described slips is fixed with respectively roller.
Further improvement as technique scheme:
Described with being also arranged at intervals with arc groove on the inner peripheral surface of tooth shell, described arc groove coordinates with roller.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy to operate, by the effect of ramp, controls roller and inwardly moves, thereby drive slips clamping tube, and its dependability is good, and operating efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model when clamping tube (not).
Fig. 2 is structural representation of the present utility model (during clamping tube).
Wherein: 1, band tooth shell; 2, ramp; 3, roller; 4, slips; 5, pipe; 6, fixed head; 7, arc groove.
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 clamp mechanism of the present embodiment, comprises band tooth shell 1, with tooth shell 1, rotates with driving the gear engagement of its rotation, with interval on the inner peripheral surface of tooth shell 1, ramp 2 is installed; The middle part being positioned at tooth shell 1 is provided with fixed head 6, fixed head 6 middle part perforates, and the bottom that is positioned at fixed head 6 is provided with a pair of slips 4 of clamping tube 5, and the outer end of slips 4 is fixed with respectively roller 3.Roller 3 rotates along ramp 2.
With being also arranged at intervals with arc groove 7 on the inner peripheral surface of tooth shell 1, arc groove 7 coordinates with roller 3.
In practical work process, by the rotation of gear drive band tooth shell 1, also and then rotate with the ramp 2 being connected with tooth shell 1, ramp 2 is from thin that one end forwards thick one end to, thereby pushing rolling wheels 3 moves to internal direction, because roller 3 and slips 4 link together, thus also inwardly motion of slips 4, thus slips 4 clampings are contained in inner pipe 5.Gear is rotated further, and because slips 4 has been clamped pipe 5, thereby stops slips 4 to continue inwardly motion, and slips 4 clips pipe 5 and will rotate together along with band tooth shell 1, thereby can complete the upper of screwed pipe 5, buckles or lower work of buckleing.It is easy to use and reliable, and operating efficiency is high.
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.
Claims (2)
1. a twisting machine clamp mechanism, is characterized in that: comprise band tooth shell (1), described band tooth shell (1) rotates with driving the gear engagement of its rotation, and on the inner peripheral surface of described band tooth shell (1), interval is provided with ramp (2); The middle part that is positioned at band tooth shell (1) is provided with fixed head (6), described fixed head (6) middle part perforate, the bottom that is positioned at fixed head (6) is provided with a pair of slips (4) of clamping tube (5), and the outer end of described slips (4) is fixed with respectively roller (3).
