Utility model content
The problem existing for above-mentioned prior art, the utility model provides a kind of long screw auger driver drilling rod automatic clamping device, when wanting dismounting drilling rod, can automatically clamping supporting seat be turned to drilling rod position drilling rod mandrel is stepped up, fixed; When not needing dismounting drilling rod, can realize automatically and quickly clamping supporting seat is rotated to permanent position, do not affect normal construction operation; Improve efficiency of construction, reduce construction cost, stop potential safety hazard.
To achieve these goals, this long screw auger driver drilling rod automatic clamping device is included in the short drill pipe that outer six square joints and interior six square joints are welded respectively in two ends, more piece short drill pipe is fixedly connected into drilling rod assembly by bearing pin II, drilling rod assembly is nested with casing outward, and casing plays the effect of protection, guide rod assembly;
On the support of described casing, by bearing pin I, connect oil cylinder, described oil cylinder is connected with one end of guiding device by bearing pin III, and the other end of described guiding device connects clamping supporting seat, on described clamping supporting seat, is fixedly connected with arc clamping plate.
Further, described guiding device is universal socket.
Further, on described casing, weld arc positioning baffle.
Compared with prior art, the beneficial effect of this long screw auger driver drilling rod automatic clamping device is:
1, adopt automatic telescopic oil cylinder, the free-extension of oil cylinder can change clamping supporting seat position automatically, and when dismounting drilling rod, oil cylinder can guarantee that clamping supporting seat does quick rotation around bearing pin, and moves to the position that can clamp drilling rod mandrel;
2, clamp that supporting seat can effectively step up by clamping device, fixing drilling rod mandrel, guarantee that drilling rod is quick, for convenience detach, reduce the cycle that manually clamps, changes, improve efficiency of construction, reduction construction cost, stops manually-operated potential safety hazard;
3, by guiding device, can regulate oil cylinder and clamp the bearing pin position between supporting seat, avoid bearing pin stressed excessive and damage.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, this long screw auger driver drilling rod automatic clamping device is included in the short drill pipe 7 that outer six square joints 2 and interior six square joints 5 are welded respectively in two ends, more piece short drill pipe 7 is fixedly connected into drilling rod assembly 3 by bearing pin II 6, drilling rod assembly 3 is outer is nested with casing 4, and casing 4 plays the effect of protection, guide rod assembly 3;
As shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, on the support of described casing 4, by bearing pin I 1, connect oil cylinder 8, described oil cylinder 8 is connected with one end of guiding device 10 by bearing pin III 9, the other end of described guiding device 10 connects clamping supporting seat 11, on described clamping supporting seat 11, is fixedly connected with arc clamping plate 12.Clamping supporting seat 11 can pass through the guide effect of stretching of oil cylinder 8 and guiding device 10 and rotate around bearing pin I 9.
