Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1 and 2, the present invention 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.
Specific works process of the present invention is as follows: when needs are from appointed place carrying safety valve to checking table verification seat, the controlled Systematical control of apparatus of the present invention carries out corresponding movement.Angle adjusted by first whirligig, makes clamp and safety valve point-blank, is pressed into hydraulic oil in the first hydraulic jack, and piston rod is extended, and first crossbeam and second cross beam slowly decline, and drives lifting support steadily to decline.Be pressed into hydraulic oil in 3rd hydraulic jack, slide block moves together along with piston rod, and clamp are advanced further, from safety valve more close to.Then the further vernier angle of the second whirligig, makes clamp just to safety valve.And then be pressed into hydraulic oil in the second hydraulic jack, clamp drop to suitable height together along with piston rod, and be pressed into hydraulic oil in clamp oil cylinder, clamping plate open, and stretch into safety valve neck; Then hydraulic oil is unloaded in clamp oil cylinder, clamping plate clamping safety valve.First hydraulic jack unloading hydraulic oil, clamp improve certain distance, ensure that there is certain altitude on safety valve and ground.Then the first whirligig rotates to an angle, and makes clamp and safety valve roughly just to checking table.First hydraulic jack unloading hydraulic oil, piston rod declines, and first crossbeam and second cross beam drive the lifting of band lifting support, make safety valve exceed checking table certain distance.3rd hydraulic jack press-in hydraulic oil, slide block moves forward together along with piston rod, when safety valve is roughly on checking table gripping mechanism, stops.Then the second whirligig fine-adjustment rotary, makes the center of safety valve just in time at three-jaw center.Then be pressed into hydraulic oil in the second hydraulic jack, allow safety valve just in time steadily drop on scroll chuck.Clamp oil cylinder press-in hydraulic oil, piston rod extends, and claw magnifies, and unclamps safety valve.Then safety valve convey mechanical arm completes carrying work.Return to reference position, prepare next safety valve of carrying.
