Specific embodiment
Reference picture 1-4, a kind of unit head 1 locking device for rock-core borer of the present utility model, rock-core borer includes
Unit head 1 and sliding sleeve 3, described sliding sleeve 3 is fixedly installed a pair the gripper shoe 5 with circular arc hatch frame, and unit head 1 sets
Put in described a pair of gripper shoe 5, be connected by rotating shaft between unit head 1 side and two gripper shoes 5, and be provided with for driving
The overturning oil cylinder 2 that dynamic unit head 1 overturns around the shaft, two gripper shoes 5 are fixedly connected with cylinder bracket 6, the bore section of overturning oil cylinder 2
It is connected with cylinder bracket 6 pivot joint, cylinder rod portion is connected with unit head 1 pivot joint.
Unit head 1 opposite side is provided with power head locking mechanism 4, and power head locking mechanism 4 includes being fixed on two gripper shoes 5
Between U-shaped mouth clamp 42, unit head 1 is provided with saddle rotary shaft 41, saddle rotary shaft 41 is arranged with handle reverse 45, turns over
Change hands handle 45 and include interior eccentric adjusting sleeve 451 and handle portion 452, interior eccentric adjusting sleeve 451 is enclosed within saddle rotary shaft 41, upset
Turnbuckle 44 is arranged with the interior eccentric adjusting sleeve of handle 45 451, turnbuckle 44 includes cannula portion 441 and bolt shank
442, cannula portion 441 is set in the interior eccentric adjusting sleeve 451 of handle reverse 45, and bolt shank 442 is used for blocking with U-shaped mouth clamp 42
Connect in succession, bolt shank 442 is also threaded with lock nut 43.The present embodiment is preferred, the eccentric throw that interior eccentric adjusting sleeve is 451
For 1.4-1.6mm.
Unit head 1 locking device of the present utility model, relies on power head locking mechanism 4 to can achieve that unit head 1 is locked
On sliding sleeve 3, rely on overturning oil cylinder 2 can realize the upset of unit head 1, specifically, unit head 1 need during locking it is only necessary to
By the bolt shank 442 of turnbuckle 44 and with reference to lock nut 43, turnbuckle 44 is stuck on U-shaped mouth clamp 42, then
Handle reverse 45 is pressed down on, interior eccentric adjusting sleeve 451 rotates around saddle rotary shaft 41, in interior eccentric adjusting sleeve 451 relatively
Thick side rotates to top position, by cannula portion 441 jack-up of turnbuckle 44, thus bolt shank 442 is strained, realizes
