The flexible drive left and right lever of oil cylinder synchronously rotates around bearing pin, drives the left and right slide block along slide rail in opposite directions or reverse slide, to realize left and right, clamps the clamping of secondary pawl to steel pipe.This device adopts automatic centering clamping mechanism can meet Automatic-clamping centering steel pipe, adopts Driven by Hydraulic Cylinder can meet the clamping force of large-diameter steel pipe.Especially in the assembling and unloading process of Hydraulic Station, adopt this device can improve efficiency of assembling.This device, simple in structure, easy and simple to handle.
Description of drawings
Fig. 1 is the utility model hydraulic-driven self-centering pipe fitting cramping arrangement front view.
Fig. 2 is each parts assembly relation schematic diagram of the utility model hydraulic-driven self-centering pipe fitting cramping arrangement.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As Fig. 1, shown in 2, hydraulic-driven self-centering pipe fitting cramping arrangement, comprise right slide block 1, the secondary pawl 2 of right clamping, left slider 3, limiting plate 4, right lever 5, oil cylinder 6, lever left 7, slide rail 8, the secondary pawl 9 of left clamping, front shroud 10, bearing pin 11, oil cylinder bearing pin 12, back shroud 13, split pin 14, screw 15.Limiting plate 4 is provided with stopper slot 41, for inverted U-shaped opening stopper slot, limiting plate 4 be screwed the back side of slide rail 8 (below), right slide block 1, left slider 3 are assemblied in respectively track 8 the right and lefts, and the upper end of right lever 5, lever left 7 is separately fixed on right slide block 1, left slider 3 with jointed shaft 17.
Described slider-actuated mechanism, formed by lever left 7, right lever 5, bearing pin 11 and oil cylinder 6, lever left and right lever middle part are equipped with hinged support plate (71,51), the hinged support plate is equipped with hinge hole (hinge hole 72 on lever left), bearing pin 11 passes the hinge hole of two hinged support plates, and lever left and right lever is hinged, in the spacing stopper slot at limiting plate 41 of bearing pin 11; The two ends of oil cylinder 6 are hinged on respectively the lower end of lever left and right lever, and the upper end of lever left is hinged on left slider, and the upper end of right lever is hinged on right slide block.
