Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
For ease of description, left end is front end in Fig. 1 main view, and right end is rear end.
As shown in Figure 1, act arm slipping mechanism described in the utility model is by rotatable pedestal 7, to be mounted on drilling machine removable
On dynamic chassis, 3 rear end of slip base is hinged on the support base 4 of pedestal 7 by the second pin shaft 10, and the front end of slip base 3 passes through the
Three pin shafts 12 and 20 piston rod of tower oil cylinder are hinged, the branch that cylinder seat passes through the first pin shaft 8 and 4 side of support base after tower oil cylinder 20
Fagging 13 is hinged, and when playing the elongation of tower oil cylinder 20, slip base 3 can be center of circle rotation, front end with second pin shaft 10 of its rear end
It lifts.3 rear end of slip base is hinged by the 6th pin shaft 16 and cylinder seat after sliding oil cylinder 18, and sliding 18 piston rod of oil cylinder passes through the 7th
Pin shaft 17 is hinged with the sliding rack 2 for being installed on 3 upper end of slip base, and sliding oil cylinder 18 can drive sliding rack 2 when making stretching motion
Make flexible sliding motion, sliding oil cylinder 18 is parallel with the sliding rail of sliding rack 2.2 front end of sliding rack by the 8th pin shaft 22 with
The supporting plate 21 of 1 lower end of turntable is hinged；21 rear end of supporting plate is hinged by the 5th pin shaft 15 and 19 piston rod of elevating ram, elevating ram
Cylinder seat is hinged by the 4th pin shaft 14 and 2 upper rear end of sliding rack after 19, when elevating ram 19 makees stretching motion, can make turntable 1
