Described clamping device comprises the second oil cylinder, mobile support saddle, and two the second oil cylinders are connected with rotary support by bolt group, the piston rod of each the second oil cylinder is provided with a mobile support saddle.When two the second oil cylinders start, two piston rods will drive mobile support saddle to realize stepping up, unclamping action.Transship to prevent oil cylinder and damage main shaft, improve frictional force during mobile support saddle gripper spindle simultaneously, each mobile support saddle is equipped with four the second Anti-skid sheets.
Described whirligig comprises rotary support, and rotary support is connected with base by limiting plate, bolt group, and described 3rd cylinder is assembled by fixed pin shaft and base, and the piston rod of the 3rd cylinder is connected with rotary support by rotary pin shaft.When the 3rd cylinder starts, piston rod will drive rotary pin shaft, rotary support rotates on base around limiting plate.
A kind of mine drill stem clamp unscrewing of the utility model mechanism, technique effect is as follows:
1), by two the first hydraulic oil cylinder driving, two sliding supports, thus fixing drilling rod.By two the second hydraulic oil cylinder driving, two mobile support saddles, thus clamp drill spindle.Drive rotary support by rotary cylinder, thus drill spindle is rotated realize locking with the internal thread of drilling rod.
2), drilling rod changed by different size rig demand in mining field can be met, accomplish " a tractor serves several purposes ", greatly reduced cost of production.

Detailed description of the invention
As shown in Fig. 1 ~ Fig. 5, a kind of mine drill stem clamp unscrewing mechanism, comprises fastening devices 1, clamping device 2, whirligig 3.
Described fastening devices 1 comprises base 4, and bearing support 8 is fixed on base 4, and two the first oil cylinders 5 are fixedly connected with base 4, the piston rod of each the first oil cylinder 5 are provided with a sliding support 6.During work, bearing support 8 is mainly by bearings drilling rod.When two the first oil cylinders 5 start, two piston rods will drive sliding support 6 to realize stepping up, unclamping action.Transship to prevent oil cylinder and damage drilling rod, improve frictional force during sliding support 6 holding drill pipe simultaneously, each sliding support 6 is equipped with four the first Anti-skid sheets 7.
Described clamping device 2 comprises the second oil cylinder 9, mobile support saddle 10, two the second oil cylinders 9 are connected with rotary support 12, the piston rod of each the second oil cylinder 9 is provided with a mobile support saddle 10.When two the second oil cylinders 9 start, two piston rods will drive mobile support saddle 10 to realize stepping up, unclamping action.Transship to prevent oil cylinder and damage main shaft, improve frictional force during mobile support saddle 2 gripper spindle simultaneously, each mobile support saddle 10 is equipped with four the second Anti-skid sheets 11.
Described whirligig 3 comprises rotary support 12, and rotary support 12 is connected with base 4 by limiting plate 13, and described 3rd cylinder 14 is assembled by fixed pin shaft 15 and base 4, and the piston rod of the 3rd cylinder 14 is connected with rotary support 12 by rotary pin shaft 16.When the 3rd cylinder 14 starts, piston rod will drive rotary pin shaft 16, rotary support 12 to rotate on base 4 around limiting plate 13.
Implementation step:
1): before rig is started working, installed to by drilling rod on bearing support 8, the piston rod simultaneously starting two the first oil cylinders, 5, two the first oil cylinders 5 promotes sliding support 6, four the first Anti-skid sheets 7 and realizes clamping, thus is fixed up by drilling rod.
2): the piston rod starting the second oil cylinder 9, second oil cylinder 9 promotes mobile support saddle 10, four the second Anti-skid sheets 11 and realizes clamping, thus is fixed on rotary support 12 by drill spindle.
3): till rig is switched to neutral gear, drill spindle is dallied.Start that the 3rd cylinder the 14, three cylinder 14 will promote rotary pin shaft 16, rotary support 12, drill spindle realize turning clockwise along limiting plate 13, thus the external screw thread of drill spindle is combined with the internal thread rotation of drilling rod on base 4 simultaneously.
4): stop the first oil cylinder 5, cylinder piston rod is retracted, and sliding support 6 and the first Anti-skid sheet 7 unclamp drilling rod.
5): stop the second oil cylinder 9, cylinder piston rod is retracted, and mobile support saddle 10 and the second Anti-skid sheet 11 unclamp drill spindle.
6): rig is switched to operation range, rig will drive drilling rod to rotate in bearing support 8 by main shaft, realizes bore operation.
7): when bore operation completes, the piston rod restarting the first oil cylinder 5, first oil cylinder 5 promotes sliding support 6, first Anti-skid sheet 7 and realizes clamping, thus is fixed up by drilling rod.
8): the piston rod restarting the second oil cylinder 9, second oil cylinder 9 promotes mobile support saddle 10, second Anti-skid sheet 11 and realizes clamping, thus is fixed on rotary support 12 by drill spindle.
9): till again rig being switched to neutral gear, drill spindle is dallied.Stop the 3rd cylinder the 14, three cylinder 14 to retract, pull rotary pin shaft 16, rotary support 12, drill spindle to realize being rotated counterclockwise on base 4 along limiting plate 13 simultaneously, thus the external screw thread of drill spindle is thrown off with the internal thread of drilling rod.
