Embodiment
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Figure 1 and 2, the utility model mainly comprises base 1, and base 1 is provided with the first whirligig 2, first whirligig 2 upper end and fixes the first column 4, first column 4 upper end fixed cross beam bracing frame 5.
Hinged second cross beam 7 rear end, piston rod front end of hinged first hydraulic jack 3, first hydraulic jack 3 on first whirligig 2, second cross beam 7 front end connects lifting support 8 through cross beam support frame 5.First whirligig 2 can drive the first column 4 of upper end to rotate together with the first hydraulic jack 3.
Cross beam support frame 5 connects first crossbeam 6 rear end, first crossbeam 6 front end connects lifting support 8.First crossbeam 6 connecting cross beam bracing frame 5 and lifting support 8, make lifting support 8 lower end form fixing fulcrum, and under the promotion of the piston rod of the first hydraulic jack 3, second cross beam 7 can drive lifting support 8 to seesaw around fixed pivot.
Be provided with chute in lifting support 8, the piston rod front end that the 3rd hydraulic jack the 14, three hydraulic jack 14 is fixed in chute one end connects the slide block 15 be slidably connected in chute.3rd hydraulic jack 14 can be with movable slider 15 to seesaw along chute.
Slide block 15 is provided with the second whirligig 9, second whirligig 9 lower end connects the second column 10, second column 10 lower end connects the second hydraulic jack 11, the piston rod front end of the second hydraulic jack 11 connects force rod 12, force rod 12 lower end connects stress support 13, stress support 13 lower end connection clamp 16.Second whirligig 9 can drive the second hydraulic jack 11 and upper link thereof to rotate together, and the second hydraulic jack 11 promotes clamp 16 by piston rod again and moves up and down.
Be provided with rolling bearing in described first whirligig 2 and the second whirligig 9, manually promote the first whirligig 2 and the second whirligig 9 rotates.
As shown in Figure 3, described clamp 16 comprise clamp oil cylinder 16.1, the piston rod front end of clamp oil cylinder 16.1 is by the left connecting rod 16.3 of pinned connection and right connecting rod 16.4, and left connecting rod 16.3 and right connecting rod 16.4 front end are respectively by pinned connection left support plate 16.5 and right support plate 16.6.The two ends of pinned connection fixed head 16.2 are passed through in the rear end of left support plate 16.5 and right support plate 16.6, and left support plate 16.5 is connected left clamping plate 16.7 and right clamping plate 16.8 with the front end of right support plate 16.6 respectively by bearing pin.
