Description
Technical field
The present invention relates to a kind of steel processed workpiece fender guard, specifically be meant easy-to-dismount outside thread petroleum machinery workpiece protective cover.
Background technology
In the middle of the parts of petroleum machinery, particularly in underground instrument, all be cylindric on most of whole workpiece, helicoid hydraulic motor for example, drilling jar, super bumper jars, conventional coring tool, hydraulic accelerator, fishing cup, strong magnetic die, die nipple, beche, anti-circulation is salvaged blue, the reversible slip socket, elevator plug, the integral type short drill pipe, kelly cock, the flechette-type back-pressure valve (BPV), drilling tool stabilizer etc., above workpiece all adopts and forges embryo spare and make by machine up, the two ends of its shaping workpiece or wherein an end have negative thread or outside thread.Wherein helicoid hydraulic motor be a kind of be power with the drill fluid, the positive displacement mud motor that can transfer fluid pressure to mechanical energy, when the mud stream that mud pump pumps is advanced section's motor through bypass disc, import and export at motor forms certain difference of pressure, promote the axis rotation of rotor around stator, and rotating speed and moment of torsion passed to drill bit by versatile spindle and transmission shaft, thereby realize drilling operation; Elevator plug is a kind of instrument that removes drill collar, and it is a short drill pipe, is connected on when being used to remove drill collar on the screw thread of drill collar so that can make a trip with elevator; For the overall dimensions of workpiece; externally threaded thickness, the externally threaded width at its two ends are all less; therefore; in the maintenance and transportation behind Workpiece shaping, all need the outside thread of workpiece is carefully protected, the outside thread that brings with the collision that prevents because of workpiece damages; in case the thread failure of workpiece; will cause sealing property to reduce, even workpiece can not use, cause scrapping.
Summary of the invention
The cylindric workpiece that the objective of the invention is to overcome present petroleum machinery provides a kind of protective cover of easy-to-dismount outside thread petroleum machinery workpiece in the difficult problem that the outside thread that machines the back workpiece damages easily in transportation and storing process.
Purpose of the present invention is achieved through the following technical solutions:
Easy-to-dismount outside thread petroleum machinery workpiece protective cover, comprise shield body, described shield body is made of end face and sidewall, and it is round table-like that integral body is, its inside is cavity structure, be provided with the negative thread that the outside thread with workpiece is complementary in inside surface of side wall, be provided with two vacancy sections through end face at least at the end face of shield body, the end face between the vacancy section is for turning round arm.Shield body is formed by connecting by end face and sidewall, end face is circular, sidewall connects and composes round table-like, end face is arranged on top side wall, in sidewall, be provided with the negative thread that the outside thread with workpiece is complementary, during use, shield body is placed on workpiece end, and rotation shield body, the screw thread of shield body and the screw thread fit of workpiece, shield body gets final product after in the whole receptosomes of the screw thread of workpiece, and the screw thread of shield body embeds in the thread pitch of surface of the work, can effectively reduce screw thread radially and the deformation axially, prevent the thread failure that it takes place because of collision; Dismounting for the ease of shield body, end face in shield body is provided with two vacancy sections through end face at least, summit portion between the vacancy section forms turns round arm, during use, hand is inserted at least two vacancy sections simultaneously, and turn the arm of turning round between the vacancy section, turn round arm and drive shield body and rotate the dismounting that can realize shield body.
Described vacancy section is four, and is uniformly distributed in the end face of shield body, and the described arm of turning round is mutually vertical and be connected to form integral body.Four hollow out zones are evenly distributed on the end face of shield body, and about end face center symmetry, and the arm of turning round between four hollow out zones forms " ten " font of overlooking on the direction, so, both has been convenient to twisting, does not also occupy the more space volume.
Described sidewall bottom is connected with the stacking ring parallel with the end face of shield body.Because shield body is round table-like, occupy certain spatial volume, for the ease of the transportation of shield body with deposit, be provided with the stacking ring in the bottom of shield body sidewall, the diameter of the internal diameter of stacking ring and shield body sidewall bottom is complementary, and is the stacking ring parallel with end face shield body.
At least be provided with two piling beds on described stacking ring, described piling bed is evenly distributed on the upper surface of stacking ring.When shield body stacks, the gravity of himself can compress shield body, the taking-up difficulty that causes shield body, in order to overcome the difficulty that is difficult to take out, the stacking ring is provided with piling bed, piling bed can keep the distance between the stacking ring of shield body, is convenient to instrument or hand and stretches between the shield body, reaches with this and is convenient to purpose separately.
Workpiece is molded into the equipment of changing to from making and uses; need through long time; the connecting bridge of workpiece particularly; long term exposure gets rusty easily in the middle of air; corrosion etc.; therefore need apply machine oil in order to the protection workpiece at surface of the work; but the easy landing of machine oil is difficult for being attached to for a long time the labor cost surface; therefore; after shield body is placed on surface of the work, rotate a circle to two weeks, in the hollow out zone, add machine oil; and then continuation rotation shield body; all enter cavity in the shield body until the outside thread of workpiece, in rotary course, machine oil is coated on the surface of workpiece screw thread with the cooperation of screw thread.
The present invention compared with prior art has following advantage and beneficial effect:
A kind of easy-to-dismount outside thread petroleum machinery workpiece protective cover of 1 the present invention, it is round table-like that shield body is on the whole, portion is provided with negative thread within it, the screw thread of shield body embeds in the thread pitch of surface of the work, can effectively reduce screw thread radially and the deformation axially, prevent the thread failure that it takes place because of collision;
A kind of easy-to-dismount outside thread petroleum machinery workpiece protective cover of 2 the present invention is provided with the stacking ring in the bottom of shield body sidewall, is convenient to the transportation of shield body and deposits;
A kind of easy-to-dismount outside thread petroleum machinery workpiece protective cover of 3 the present invention, the stacking ring is provided with piling bed, piling bed can keep the distance between the stacking ring of shield body, is convenient to instrument or hand and stretches between the shield body, reaches with this and is convenient to purpose separately;
A kind of easy-to-dismount outside thread petroleum machinery workpiece protective cover of 4 the present invention, be provided with the hollow out zone at end face, turn round the dismounting that arm is convenient to shield body between the hollow out zone, the hollow out zone is also simultaneously as oil hole, helps the longer-term storage of workpiece and transportation, maintenance.
