Summary of the invention
The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art part, and blanking plug in a kind of oil pipe that can provide convenience for interim shutoff oil pipe is provided.
The utility model is by the following technical solutions:
Blanking plug in a kind of oil pipe, comprise top connection, center-pole, cut off pin, positioning support, location claw, torsionspring, shop bolt, briquetting, leather cup cover, leather cup, leather cup seat, anchor head, slide block, block, the location claw is connected by shop bolt with positioning support, torsionspring is housed on the shop bolt, and the location claw tightly is stuck in the serrated portion on the center-pole under the tensile force effect of torsionspring; Center-pole passes from briquetting, leather cup cover, leather cup, leather cup seat center, center-pole lower end and anchor head threaded engagement; Leather cup and center-pole interference fit, and cup packing mouth down; Anchor head bilateral symmetry position respectively connects a slide block, and slide block and anchor head adopt oat tail groove structure to be slidingly matched the sliding distance of stop limits slide block; It is characterized in that it also comprises the bump cover, being processed with on the axial direction of bump cover can be for the hole of center-pole slip, the bump sleeve wall is processed with along axis direction can be for cutting off the groove that pin slides, groove is about the axis symmetry of bump cover, bump set upper side and top connection threaded engagement, bump cover lower end is connected with center-pole by cutting off pin, cuts off pin and slides in the groove that bump puts that can to drive center-pole mobile in the hole that bump puts.
Effect of the present utility model is: utilize the effect of blanking plug self gravitation to make its free-falling during following blanking plug, utilize the mode of bump to compress the shutoff of leather cup realization oil pipe, can regain down the blanking plug device easily by cutting off pin, the broached-tooth design of location claw and center-pole forms unidirectional self-lock mechanism, improves the stability of shutoff.The oat tail groove structure of anchor head and slide block is slidingly matched, and utilizes block to the restriction of slide block sliding distance blanking plug to be pushed up on can be owing to high-voltage oil liquid after the work and moves, improve the safety of shutoff work.The utility model is not only simple in structure, and safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation
Fig. 2 is an A place partial enlarged drawing among Fig. 1
Among the figure, top connection 1, bump cover 2, center-pole 3, cut off pin 4, positioning support 5, location claw 6, torsionspring 7, shop bolt 8, briquetting 9, leather cup cover 10, leather cup 11, leather cup seat 12, anchor head 13, slide block 14, block 15
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
The utility model is mainly by top connection 1, bump cover 2, center-pole 3, cut off pin 4, positioning support 5, location claw 6, torsionspring 7, shop bolt 8, briquetting 9, leather cup cover 10, leather cup 11, leather cup seat 12, anchor head 13, slide block 14, block 15, being processed with on bump cover 2 axial directions can be for the hole 16 of center-pole 3 slips, bump cover 2 barrels are processed with along axis direction can be for cutting off the groove 17 that pin 4 slides, groove 17 is about the axis symmetry of bump cover, bump cover 2 upper ends and top connection 1 threaded engagement, bump cover 2 lower ends are connected with center-pole 3 by cutting off pin 4, cut off slip in the groove 17 of pin 4 on bump cover 2 can drive center-pole 3 clashing into overlap in 2 the hole 16 mobile.Location claw 6 is connected by shop bolt 8 with positioning support 5, torsionspring 7 is housed on the shop bolt 8, location claw 6 tightly is stuck in the serrated portion on the center-pole 3 under the tensile force effect of torsionspring 7, restriction positioning support 5 can only move downward and can not move upward; Center-pole 3 passes center-pole 3 and anchor head 13 threaded engagement from briquetting 9, leather cup cover 10, leather cup 11, leather cup seat 12 centers; Leather cup 11 and center-pole 3 interference fit, and leather cup 3 seals are down; Anchor head 13 bilateral symmetry positions respectively connect a slide block 14, slide block 14 adopts oat tail groove structure to be slidingly matched with anchor head 13, the sliding distance of block 15 restriction slide blocks 14, anchor head 13 can only be moved down in oil pipe, can not move up, this has guaranteed that blanking plug pushes up on can be owing to high-voltage oil liquid behind the shutoff oil pipe and has moved, has improved the safety of shutoff;
During operation, this blanking plug is delivered by wire rope or pipe bar, when delivering with wire rope, blanking plug under the effect of gravity, free-falling.After being shipped to the precalculated position, on carry wire rope, blanking plug integral body is up, slide block 14 contacts with tube inner wall along the inclined-plane downslide of anchor head 13, make blanking plug on move the restriction that is subjected to slide block 14 and tube inner wall coupling mechanism force, move and make the wire rope tensioning on blanking plug stops, cutting off pin 4 this moment and be on the bump cover 2 groove 17 bottom.Transfer wire rope, bump cover 2 moves downward under action of gravity, because the effect of groove 17, cut off the main part that pin 4 connecting center-pole 3 blanking plugs such as grade and keep motionless, bump cover 2 bump positioning supports 5, make positioning support 5 move downward compression leather cup 11 with respect to center-pole 3, the end opening pressurized of leather cup 11 is expanded to tube inner wall, because the restriction that positioning support 5 is located claw 6 can only move downward and can not move upward, this has just guaranteed the irreversibility of leather cup 11 compressions, cuts off the top that pin 4 is in the groove 17 on the bump cover 2 this moment.On carry wire rope, top connection 1 moves upward with bump cover 2, because the effect of anchor head 13 and slide block 14, it is motionless that the blanking plug main body keeps, make cut off pin 4 be on the bump cover 2 groove 17 bottom, transfer wire rope, utilize bump cover 2 bump positioning supports 5 to realize compressing leather cup 11.Repeat aforesaid operations, closely contact with tube inner wall, reach the effect of shutoff oil pipe up to leather cup 11.Carry wire rope on continuing this moment, cuts off pin 4 and cut off, and promptly recoverable wire rope is finished the work of shutoff oil pipe.
If adopt the pipe bar to deliver, then can directly utilize pipe pole pair bump cover 2 application of forces, make its bump positioning support 5, make positioning support 5 move downward compression leather cup 11 with respect to center-pole 3, accelerate the shutoff process.
