Abstract

The invention relates to a clamping mechanism of a pipe twisting machine. The clamping mechanism comprises an outer shell with teeth, wherein the outer shell with teeth is meshed with a gear driving the outer shell with teeth to rotate for rotation, slope plates are installed on the inner circumferential surface of the outer shell with teeth at intervals, a fixing plate is installed in the middle of the outer shell with teeth, a hole is formed in the middle of the fixing plate, the lower portion of the fixing plate is provided with a pair of slips for clamping a pipe, and outer ends of the slips are respectively and fixedly provided with an idler wheel. The clamping mechanism is compact ad reasonable in structure and convenient to operate, the idler wheels are controlled to move inwards through the action of the slope plates to drive the slips to clamp the pipe, and the clamping mechanism is good in use reliability and high in work efficiency.

Description

Twisting machine clamp mechanism
Technical field
The present invention 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.
Summary of the invention
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 solution adopted in the present invention is as follows:
A 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.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, 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 invention when clamping tube (not).
Fig. 2 is structural representation of the present invention (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 invention 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 Cong Bao get one end forward Hou 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 explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
