Background technology
Jianghan Oil-field is positioned at the oil field on Yangtze middle reaches Jianghan Plain.In process of oil production, when the high pressure valve on water injection pipe, transport pipe, high pressure valve seal ring etc. need to change, must expand or spacing between collapsible tube; Counter weight of beam unit on crank before and after many places such as adjustment balance etc., usually need to use and expand or service tools that convergent force is very large.According to the knowledge of the applicant, existing service tools is as screw jack, hydraulic jack etc., and it all only has jacking the planning function, and ungauged regions tractive function.When carrying out outside jacking expansion to the equipment needed repairing, when inwardly shrinking tractive again, screw jack, hydraulic jack are then helpless, bring very big inconvenience to maintenance.The solution that this problem has never had.
Summary of the invention
The purpose of this utility model is, for existing service tools as screw jack, hydraulic jack etc., only has jacking the planning function, and ungauged regions tractive function.When carrying out outside jacking expansion to the equipment needed repairing, when inwardly shrinking tractive again, screw jack, hydraulic jack are helpless, bring the problem of greatly inconvenience, propose a kind of mechanical retractable device to maintenance.
Technical solution of the present utility model is, mechanical retractable device is combined by pipe expansion joint connector, feather key bar, pipe expansion joint housing, rectangle screw axis, flexible sliding sleeve, copper nut, boosting-rod, arrow wheel transfer device, small bevel gear wheel shaft, bevel pinion, large bevel gear, thrust baring, screw mandrel shaft block, screw mandrel jam nut.Small bevel gear wheel shaft one end is by vowing that wheel transfer device is connected with boosting-rod, and the other end installs bevel pinion.Rectangle screw axis adopts copper nut, prevents from sticky sticking occurs when rotating with flexible sliding sleeve square thread band power; Rectangle screw axis and flexible sliding sleeve control it by feather key bar and make fore and aft motion and rectangle screw axis of getting along well produces and rotates; Rectangle screw axis one end is coordinated by square thread with flexible sliding sleeve; The other end installs large bevel gear, thrust baring, and top is locked by screw mandrel jam nut through screw mandrel shaft block.Bevel pinion is engaged with large bevel gear, and small bevel gear wheel shaft rotates and then drives rectangle screw axis to rotate, and then it is flexible to drive flexible sliding sleeve to produce.
Mechanical retractable device two ends can with lengthening adjusting screw(rod), lengthen pipe link, annular is connected and fixed snap ring, rotary connecting joint is connected by internal and external threads.Lengthen adjusting screw(rod), lengthen that pipe link, annular are connected and fixed snap ring, rotary connecting joint is that internal and external threads connects, mechanical retractable device and annular are connected and fixed can to follow between snap ring, rotary connecting joint to increase according to needs or reduce and lengthen adjusting screw(rod) or lengthen pipe link.
Principle of work of the present utility model is, when the high pressure valve on water injection pipe, transport pipe, high pressure valve seal ring etc. need to change, when must expand or shrink its spacing, the annular at pipe expansion joint two ends is connected and fixed snap ring, rotary connecting joint is fixed on docking facility.Rotate boosting-rod by hand, (during boosting-rod clickwise, pipe expansion joint expands outwardly; During boosting-rod left-hand revolution, pipe expansion joint inwardly shrinks) rotation of boosting-rod drive small bevel gear wheel shaft, bevel pinion also rotates thereupon.Because bevel pinion is engaged with large bevel gear, large bevel gear also rotates thereupon thus drives rectangle screw axis to rotate, and then it is flexible to drive flexible sliding sleeve to produce.Thus reach the equipment room needed repairing apart from the object of expanding or shrinking.
The beneficial effect of a kind of mechanical retractable of the utility model device is: not only expansible, but also to shrink; Easy to use, quick, laborsaving, simple to operate, safe and reliable.

Detailed description of the invention
Below, embodiment of the present utility model is described with reference to the accompanying drawings in detail.
As shown in Figure 1, a kind of mechanical retractable device of the utility model is combined by pipe expansion joint connector (1), feather key bar (2), pipe expansion joint housing (3), rectangle screw axis (4), flexible sliding sleeve (5), copper nut (6), boosting-rod (7), arrow wheel transfer device (8), small bevel gear wheel shaft (9), bevel pinion (10), large bevel gear (11), thrust baring (12), screw mandrel shaft block (13), screw mandrel jam nut (14).Small bevel gear wheel shaft (9) one end is by vowing that wheel transfer device (8) is connected with boosting-rod (7), and the other end installs bevel pinion (10).Rectangle screw axis (4) adopts copper nut (6), prevents from sticky sticking occurs when rotating with flexible sliding sleeve (5) square thread band power; By feather key bar (2), rectangle screw axis (4) and flexible sliding sleeve (5) control that it makes fore and aft motion and rectangle screw axis (4) of getting along well produces and rotates; Rectangle screw axis (4) one end is coordinated by square thread with flexible sliding sleeve (5), and the other end installs large bevel gear (11), thrust baring (12), and top is locked by screw mandrel jam nut (14) through screw mandrel shaft block (13).Bevel pinion (10) is engaged with large bevel gear (11), and small bevel gear wheel shaft (9) rotates and then drives rectangle screw axis (4) to rotate, and then it is flexible to drive flexible sliding sleeve (5) to produce.
As shown in Figure 2, mechanical retractable device two ends can with lengthening adjusting screw(rod) (21), lengthen pipe link (18), annular is connected and fixed snap ring, rotary connecting joint (15) is connected by internal and external threads.Lengthen adjusting screw(rod) (21), lengthen pipe link (18), annular is connected and fixed snap ring, rotary connecting joint (15) is internal and external threads connection.Mechanical retractable device and annular are connected and fixed can to follow between snap ring, rotary connecting joint (15) to increase according to needs or reduce and lengthen adjusting screw(rod) (21) or lengthen pipe link (18).
When the high pressure valve on water injection pipe, transport pipe, high pressure valve seal ring etc. need to change, when must expand or shrink its spacing, mechanical retractable device two ends and annular are connected and fixed snap ring, rotary connecting joint (15) is fixed on docking facility.Rotate boosting-rod (7) by hand, (during boosting-rod clickwise, pipe expansion joint expands outwardly; During boosting-rod left-hand revolution, pipe expansion joint inwardly shrinks) boosting-rod (7) drive rectangle screw axis (4) rotation, bevel pinion (10) also rotates thereupon.Because bevel pinion (10) is engaged with large bevel gear (11), large bevel gear (11) also rotates thereupon thus drives rectangle screw axis (4) to rotate, and then it is flexible to drive flexible sliding sleeve (5) to produce.Thus reach the equipment room needed repairing apart from the object of expanding or shrinking.
