The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model:
A kind of casing-pipe clamping device for full-casing-pipe full-slewing drilling machine comprises transmission case 1, clamping cylinder 4, connecting rod 3, voussoir 7, pivoting support 2 and 11, pivoting support outer ring 2-1, pivoting support inner ring 2-2, reducing spacer 8 and pot cone 10; Described voussoir 7 is connected with pivoting support outer ring 2-1 by connecting rod 3, and pivoting support inner ring 2-2 is connected with transmission case 1; Described reducing spacer 8 is the fan-shaped arc plate, and radius of circle equates with the exradius of sleeve pipe 12 in the arc plate, and the extrados of reducing spacer 8 is installed in voussoir 7 inboards by bolt; Described pot cone 10 is by transmission case 1 and reductor 6, and hydraulic motor 9 connections obtain power, and the inner ring of pot cone 10 is made the trumpet type taper hole, and the tapering of described trumpet type taper hole is consistent with the tapering of the oblique cambered surface of voussoir 7; Described clamping cylinder 4 is four, and four clamping cylinders 4 link together lift platform 13 and transmission case 1.Four clamping cylinder 4 equal circumference are distributed on the lift platform 13.The clamp mechanism that described voussoir 7, connecting rod 3 and reducing spacer 8 form is six groups or eight groups, and six groups or eight groups of clamp mechanism are uniformly distributed along the circumference at sleeve pipe 12 peripheries.Described connecting rod 3 upper ends are hinged by jointed shaft I 3-2 and support I 3-1, and described support I 3-1 upper end is bolted on the 2-1 of pivoting support outer ring; Connecting rod 3 lower ends are hinged by jointed shaft II 3-3 and voussoir 7.The piston rod of described clamping cylinder 4 is connected with lift platform 13 by support 5, and the cylinder body of clamping cylinder 4 is connected with transmission case 1.
By for the effect of further understanding structural feature of the present utility model, application technology means and institute's expection and reaching, show mode of occupation of the present utility model be described below:
Before the use, adjust support oil cylinder 15, make base 16 parallel to the ground, if rat holing, base 16 is adjusted to the position with the inclined hole central vertical.According to the difference of 12 mouthfuls of external diameters of sleeve pipe, select corresponding reducing spacer 8 to be installed on the voussoir 7.
During use, rodless cavity to clamping cylinder 4 is sent into hydraulic oil synchronously, the piston rod elongation of clamping cylinder 4, cylinder body promotes to move on transmission case 1, connecting rod 3 and the voussoir 7, this moment, the inclined-plane of voussoir 7 broke away from the restriction that pot is bored 10 inclined-planes, and reducing spacer 8 is automatically outwards mobile and sleeve pipe 12 disengagings under 7 drives of wedge chopsticks.Sleeve pipe 12 is put between six reducing spacers 8, rod chamber to clamping cylinder 4 is sent into hydraulic oil synchronously, the piston rod retraction of clamping cylinder 4, cylinder body pulling transmission case 1, connecting rod 3, voussoir 7 and reducing spacer 8 move down, in descending process, the inclined-plane of voussoir 7 is bored under the restriction on 10 inclined-planes and reducing spacer 8 moves simultaneously at pot, and reducing spacer 8 intrados move closer to sleeve pipe 12 outer walls, until reach the clamped condition of setting.Because six voussoirs 7 are simultaneously stressed, guarantee that sleeve pipe 12 distortion are little, centering is good., along with the increase of clamping cylinder 4 charge oil pressures, the clamping force of clamp sleeve 12 increases.
After sleeve pipe 12 clamps, primer fluid pressure motor 9, the output shaft of reductor 6 drives upper rotary support outer ring 2-1 by transmission case 1 and rotates, and upper rotary support outer ring 2-1 drives voussoir 7 by connecting rod 3 and pot cone 10 that is attached thereto, reducing spacer 8 drive sleeve pipes 12 cut and creep into.
The above; be better case study on implementation of the present utility model; be not that the utility model is imposed any restrictions; every any simple modification, change and equivalent structure of above embodiment being done according to the utility model technical spirit changes, and all still belongs in the protection domain of technical solutions of the utility model.
