Description
Technical field
The utility model relates to the production equipment field of tube rolling line, is specially a kind of locking top device.
Background technology
Oil and natural gas is human important energy source, and petroleum pipeline production grows up rapidly in China.But in the perforation process of pipe production,, cause the top and then cause a series of serious accidents because the top lock is not tight.
In the locking device of prior art: a kind of is to process one section screw thread on the top that push rod protracts, be used for matching with the internal thread of top, reach the purpose of locking by screw thread, the drawback of this method is, in the operation of rolling, screw thread revolves tighter and tighter, causes the top not follow and changes, every rolling hundreds of props up and will change push rod, influences rhythm of production; A kind of is to lock by hydraulic cylinder, and hydraulic cylinder links to each other with cooling water pipe, and cooling water pipe links to each other with pull bar, one boss is arranged on the pull bar, when hydraulic cylinder is gone to stroke forward, promote water pipe and pull bar, make the pull bar boss just in time arrive the position of locking hoodle, make the locking hoodle overhanging, be stuck on the groove of top, thus locking top, when changing the top, hydraulic cylinder reclaims, pulling water pipe and push rod return away, boss and the dislocation of locking hoodle, hoodle retraction, can easy removal come directly towards, this method can be saved the time of changing the top, and is more convenient, still, because the following aspects causes relatively difficulty of locking:
(1) hydraulic cylinder is walked less than stroke because the several factors build-up of pressure is not enough, and boss is less than the locking position;
(2) the difficult and assurance of water pipe entire length;
(3) rotation in the operation of rolling causes the water pipe bending, and air line distance shortens, and boss is less than the locking position;
(4) because vibration is bigger, the ground square nut that water pipe is connected with pull bar is often loosening;
(5) because rotary speed is different, the boss wearing and tearing, hoodle stretches out inadequately.
Summary of the invention
At the problems referred to above, the utility model provides a kind of locking top device, when can guarantee that locking state is stable, is convenient for changing the top, and simple in structure, low cost of manufacture.
A kind of locking top device, its technical scheme is such: it comprises the top, push rod, hoodle, push rod, described push rod has boss, the afterbody of described top is installed in the cavity and is had hoodle screens groove, it is characterized in that: the afterbody of described top is set in the head of connector, the afterbody of described connector connects the front portion of described push rod, the central shaft of described connector partly has the through hole that runs through, described push rod is housed in the described through hole successively, spring, the both sides of spring are mounted on the rear end face of described push rod respectively, the front end face of push rod, the tail end of described push rod is an evagination round platform, the afterbody periphery of described connector has the rotating shaft through hole, be set with rotating shaft in the described rotating shaft through hole, the lower surface of described rotating shaft is a step surface, vertical plane between low step surface and high step surface is pressed on the front end face of described evagination round platform, the head periphery of described connector has hoodle through hole is installed, hoodle is installed on described hoodle and installs in the through hole, and two of described hoodle is mounted on described hoodle screens groove respectively, boss.
It is further characterized in that: the front portion of described push rod is set in the afterbody of described connector, and seals by sealing shroud;
Described hoodle is installed the head periphery that through hole is distributed in described connector;
The inner water tube of described push rod is communicated with described connector.
After adopting structure of the present utility model, rotating shaft, the low step surface of rotating shaft and the vertical plane between high step surface drive the evagination round platform and reclaim, and then drive the push rod recovery, make the boss of push rod and the location dislocation of hoodle, thereby hoodle and hoodle screens groove unclamp, the locking effect disappears, can dismantle the top this moment, changes new top, and it is convenient, simple to change the top process; Afterwards, the rotating shaft of circling round is under the effect of spring, push rod advances, and makes boss just in time arrive position under the hoodle, promotes hoodle and stretches out, hold out against hoodle screens groove, locking top, its locking stroke relies on rotating shaft control, conveniently accurately, locking state is stable, in the operation of rolling, integral body is rotated together, and boss can not wear and tear, so guarantee the in stable condition of its locking, and overall structure is simple, low cost of manufacture.
