Abstract
The utility model belongs to oil field workover rigs, and particularly relates to a multi-purpose hydraulic workover rig. The multi-purpose hydraulic workover rig comprises a footing (1), a lead screw (2), a nut (3), an upper slip housing (11) and a lower slip housing (4), wherein two oil cylinder sleeves (8) which are the same are symmetrically fixed between the upper slip housing (11) and the lower slip housing (4) in an axial direction; a piston rod I (9) and a piston I (7) are mounted in each sleeve (8); a slip seat (13) is mounted in the inner center of the upper slip housing (11) as well as in that of the lower slip housing (4); a slip (14) is mounted between the slip seats (13); the periphery of the slip (14) is fixed through a pressure plate (12); oil cylinders (16) are mounted on four inner edges of the upper slip housing (11) as well as on those of the lower slip housing (4) in radial directions; pistons II (17) are mounted in the oil cylinders (16); and end surfaces are sealed through oil cylinder covers (15). The multi-purpose hydraulic workover rig has the advantages that multiple purposes can be realized through one machine; the investment for equipment maintenance is saved; the operation is safe and reliable; the size is small; the weight is light; and the use is convenient.
Description
Technical field
The utility model belongs to oil field well workover machinery, particularly a kind of multifunction hydraulic workover rig.
Background technology
At present, the oil field, home and abroad is for pulling out the unfreezing operation by force, press down the tubing string operation, the anti-top operation of tubing string, boring the anti-top operation of plug etc. and need to adopt light maintenance and overhaul facilities and usefulness, do not have a kind ofly can solve the equipment that above-mentioned operation can both be finished, to finishing equipment that light maintenance can satisfy, so just can reduce workover cost just without overhaul facilities.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides that a kind of volume is little, in light weight, cost is low, saves the multifunction hydraulic workover rig of workover cost.
The technical scheme that the utility model technical solution problem adopts is: the multifunction hydraulic workover rig comprises footing, leading screw, screw, on, the lower slips housing, be characterized in last, axial symmetry is fixedly adorned two identical oil cylinder cylinder sleeves between the lower slips housing, dress piston rod one and piston one in the cylinder sleeve, last, dress slip spider in center in the lower slips housing, be installed between the slip spider watt, the slips periphery is fixed with pressing plate, last, four edge's radial direction charge of oil cylinders in the following watt of housing, dress piston two in the oil cylinder, end face seals with oil cylinder cover, oil cylinder bolt and last, the lower slips housing is located by connecting.Piston rod two flexibly connects with slide block with slip spider.
The beneficial effects of the utility model are: the multifunction hydraulic workover rig can be realized one-machine-multi-function, saves the maintenance of equipment investment; Realize operated from a distance, safe and reliable; Volume is little, in light weight, and is easy to use.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is a multifunction hydraulic workover rig structure sectional view.
Fig. 2 is the A-A sectional view of Fig. 1.
Among the figure, the 1-footing; The 2-leading screw; The 3-screw; 4-lower slips housing; The 5-round nut; Cylinder cap under the 6-; 7-piston one; The 8-cylinder sleeve; 9-piston rod one; 10-upper cylinder half cap; 11-upper slips housing; The 12-pressing plate; The 13-slip spider; The 14-slips; The 15-oil cylinder cover; The 16-oil cylinder; 17-piston two; The 18-slide block; The 19-spring; The 20-double-screw bolt; 21-piston rod two;
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, multifunction hydraulic workover rig footing 1, leading screw 2 are fixed on the lower slips housing 4 by screw 3, and following cylinder cap 6 is fixed on lower slips housing 4 upper ends by double-screw bolt 20; Cylinder sleeve 8 is threaded with following cylinder cap 6, and the upper end connects upper cylinder half cap 10; Piston rod 1 is in cylinder sleeve 8 inside, and the lower end connects round nut 5, and piston 1 is fixed on the piston rod 1.Upper slips housing 11 two ends are connected with piston rod 9 upper ends, form with piston rod 1, can up or decline.Pressing plate 12, slip spider 13, slips 14, spring 19 are formed clamping body in upper slips housing 11, be connected with piston 2 17 by slide block 18.Oil cylinder 16 is fixed on the upper slips housing 11 by double-screw bolt 20, and left end has oil cylinder cover 15 airtight, and piston rod 2 21 flexibly connects with slip spider 13 usefulness slide blocks 18.
The operating principle of multifunction hydraulic workover rig is: by hydraulic control, pressurizeing in cylinder sleeve 8 promotes piston 1, drives piston rod 1 and the 11 whole up or declines of upper slips housing, thereby reaches hoisting and pressing action of tubing string; Pressurization in oil cylinder 16 promotes piston 2 17, drives clamping body that pressing plate 12, slip spider 13, slips 14, spring 19 form and move ahead or retreat upper slips housing 11 in, thereby reach holding tightly and unclamping action of tubing string.
