Abstract
The utility model relates to a mine rig drill stem adjustable clamping mechanism, which belongs to the field of mine drilling machinery and comprises a substrate. The substrate is fixedly provided with a guide rail and a lead screw seat, wherein the guide rail is provided with a sliding rack; the lead screw seat is provided with a lead screw; the lead screw is provided with a lead screw nut; the lead screw nut is fixedly arranged on the sliding rack; the top of the sliding rack is provided with a hoop device; the hoop device comprises a base and two hoops; the two hoops are symmetrically arranged and are connected together through a rotating shaft and the base; the two hoops are respectively provided with an arc-shaped groove; the arc-shaped grooves are provided with clamping blocks; the clamping blocks can be directly clamped on a drill stem body; one hoop is provided with a screw rod with a hand wheel; and the other hoop is provided with a bolt hole. In the utility model, the drill stem can loosen the hooks when drilling, and the hooks are far away from the drill stem through regulating the sliding rack to avoid contacting with the drill stem; the clamping blocks do not damage a blade of the drill stem when clamping the drill stem with the helical blade, thereby achieving the goals of clamping the drill stem and not damaging the blade of the drill stem.
Description
Technical field:
The utility model belongs to mining boring field of mechanical technique, is specifically related to a kind of mine jumbo drilling rod and can regulates clamping mechanism, and drilling rod fixedly clamped when it was mainly used in coal mine roadway boring.
Background technology:
Before the utility model was made, traditional mine jumbo drilling rod clamping mechanism was generally realized clamping by two hydraulic jacks, but it is when clamping has the drilling rod of helical blade, fragile drilling rod blade, spark appears in easy and drilling rod generation friction in boring procedure, brings unsafe factor.And unadjustable position in operation process in case drilling rod breaks away from clamping mechanism, clamp drilling rod again, and is relatively more difficult, so the scope of application is little, and mechanism's complexity, price are also high.
Summary of the invention:
The utility model aims to provide and a kind ofly can clamp drilling rod, does not also damage the mine jumbo drilling rod of drilling rod blade and can regulate clamping mechanism.
The utility model comprises pedestal, is installed with guide rail, screw rodb base on the pedestal, and guide rail is provided with balladeur train, and screw rodb base is provided with screw mandrel, and screw mandrel is provided with the feed screw nut, and the feed screw nut is fixedly mounted on the balladeur train, and the top of balladeur train is provided with the anchor ear device.
Described anchor ear device comprises base, two anchor ears, two anchor ears are symmetrical arranged and link together by rotating shaft and base, be equipped with arc groove on two anchor ears, arc groove is provided with grip block, grip block can directly be clamped on the drilling rod body of rod, one of them anchor ear is provided with the screw rod that has handwheel, and another anchor ear is provided with bolt hole.
When the utility model is holed at drilling rod, can unclamp anchor ear, and by regulating balladeur train away from drilling rod, avoid contacting with drilling rod, its grip block can directly be clamped on the drilling rod body of rod, when clamping has the drilling rod of helical blade, do not damage the blade of drilling rod, thereby reach the purpose that not only clamps drilling rod but also do not damage the drilling rod blade.
It is little to the utlity model has volume, and mechanism is simple, the advantage of adjustable position.

The specific embodiment:
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail, should be appreciated that preferred embodiment only for the utility model is described, rather than in order to limit protection domain of the present utility model.
Embodiment: Fig. 1, shown in Figure 2, present embodiment comprise pedestal 10, the parallel guide rail 7,12 that is equipped with on the pedestal 10, and pedestal 10 is equipped with screw rodb base 18 by bolt, and screw mandrel 9 is arranged on the screw rodb base 18,
The anchor ear device comprises base 10, left side anchor ear 1, right anchor ear 3, left side anchor ear 1, right anchor ear 3 is symmetrical arranged and links together by rotating shaft 16 and base 17, cottor pin 15 prevents that rotating shaft 16 from coming off, left side anchor ear 1, be equipped with arc groove on the right anchor ear 3, be fixed with left grip block 1-1 on the arc groove of left side anchor ear 1, be fixed with right grip block 3-1 on the arc groove of right anchor ear, two grip blocks can directly be clamped on the drilling rod body of rod, pass through bearing pin 13 on the anchor ear 1 of a left side, cottor pin 14 is equipped with threaded rod 2, one end of threaded rod 2 is equipped with handwheel 4, cottor pin 5 prevents that handwheel 4 from coming off, and right anchor ear 3 is provided with the bolt hole that passes threaded rod 2.
The course of work of present embodiment is as follows: when dismounting drilling rod, regulate screw mandrel 9, make balladeur train 6 move to left anchor ear 1, right anchor ear 3 can be held tightly till the position of drilling rod, sees Fig. 5; To stacks the time, left anchor ear 1, right anchor ear 3 first clamping drilling rods are regulated screw mandrel 9 then, make it and stacks are in same axis and are convenient to dock, and see Fig. 6; When boring, unclamp left anchor ear 1, right anchor ear 3, descend and avoid drilling rod by screw mandrel 9, balladeur train 6, see Fig. 4.Can avoid like this in boring procedure, drilling rod and clamping mechanism friction produce spark, prevent to produce unsafe factor.
