Abstract
Disclosed is an oil and water well mouth flange bolt disassembly and assembly spanner dropping prevention device. The oil and water well mouth flange bolt disassembly and assembly spanner dropping prevention device is characterized in that an upper flange and a lower flange are connected into a whole through a plurality of bolts and nuts, a polygon head of each bolt faces downward, threaded rods are welded on sleeves, the threaded rods are respectively vertical to the sleeves, lower nuts are respectively connected with the threaded rods, an inner polygon of each sleeve sleeves the polygon head of each bolt, insertion pieces are inserted between the upper flange and the lower flange after the insertion pieces sleeve the threaded rods, the lower nuts are connected with the threaded rods, the insertion pieces are located between two bolts after the insertion pieces sleeve the threaded rods and are inserted between the upper flange and the lower flange, and can not rotate, the polygonal sleeves which sleeve the heads of the bolts can not rotate, and therefore the bolts can not rotate, and the nuts can be rotated and dismounted by using a tool. Due to the fact that the insertion pieces can not fall, workers do not need to support the sleeves, the workers can keep far away from the nuts, and if the nuts can not be demounted due to corrosion, the workers can use a sledge hammer to knap the nuts, and then can conveniently and rapidly dismount the nuts. Accordingly, the oil and water well mouth flange bolt disassembly and assembly spanner dropping prevention device has good practicability.
Description
Technical field
The utility model is a kind of instrument of dismounting pipeline connecting flange, particularly a kind of oil-water well wellhead flange bolt disassembly spanner anti-drop device.
Background technology
Pipeline connecting flange is fixed into one by bolt, nut, at the scene when dismounting flange bolt, nut need to two spanners could be by its dismounting, one of them spanner is used for screwing bolt, nut, spanner is for preventing that the bolt of the other end or nut are in company with rotation, and two spanners need to have respectively operating personnel holding up.Therefore, use instrument many at present in the time of dismounting flange bolt, nut, operating personnel are also many.When flange is during in specific position, the bad installation of spanner, operating personnel's body is difficult to put in place, and dismounting flange is very inconvenient, and labour intensity is large.In the time can not dismantling after nut corrosion, knocking with sledgehammer is best dismounting way, but owing to having personnel holding up spanner, dare not knock nut with sledgehammer, causes in outdoor well head coupling nut dismounting not get off.
Summary of the invention
The purpose of this utility model is a kind of oil-water well wellhead flange bolt disassembly spanner anti-drop device of design, makes its dismounting flange bolt, nut convenient, fast.
The purpose of this utility model is achieved in that and comprises nut, upper flange, lower flange, bolt, upper flange, lower flange overlap bolt by counting, nut links into an integrated entity, the polygon head of bolt under, also comprise inserted sheet, upper cap nut, lower nut, screw rod, sleeve, screw rod is welded on sleeve, screw rod is vertical with sleeve, lower nut is connected on screw rod, the inner polygon of sleeve is sleeved on the polygon head of bolt, after inserted sheet is through on screw rod, insert between upper flange, lower flange, lower nut is connected with screw rod.
The beneficial effects of the utility model are: inserted sheet is through and on screw rod, inserts upper flange, after between lower flange, inserted sheet is between two bolts, inserted sheet can not rotate, making to entangle the polygonal sleeve of bolt head can not rotate, also just make bolt not rotate, just can be disassembled with instrument rotary nut, because inserted sheet can not fall, do not need workman to hold sleeve, workman can be away from nut, if nut does not get off because of corrosion dismounting, just can knock nut with sledgehammer, can be convenient, fast nut is disassembled, therefore, the utlity model has good practicality.
Brief description of the drawings
Accompanying drawing is the installation diagram of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As seen from the figure, embodiment of the present utility model comprises nut 1, upper flange 2, inserted sheet 3, lower flange 4, upper cap nut 5, lower nut 6, screw rod 7, sleeve 8, bolt 9, upper flange 2, lower flange 4 are linked into an integrated entity by number cover bolt 9, nut 1, the polygon head of bolt 9 under, screw rod 7 is welded on sleeve 8, screw rod 7 is vertical with sleeve 8, lower nut 6 is connected on screw rod 7, the inner polygon of sleeve 8 is sleeved on the polygon head of bolt 9, after inserted sheet 3 is through on screw rod 7, insert between upper flange 2, lower flange 4, lower nut 6 is connected with screw rod 7.
Regulate the position of lower nut 6 on screw rod 7 according to the thickness of lower flange 4, make its upper cap nut 5, lower nut 6 can clamp inserted sheet 3, the position of wearing screw rod 7 on inserted sheet 3 is elongated slot, and it not only can be through on screw rod 7, also can insert between upper flange 2, lower flange 4.
