Abstract
The utility model relates to an unloading tool for a swim beam type oil pumping unit crankpin and relates to a double force locking sleeve. The front part of sleeve bores are first orthohexagonal apertures which can be sleeved on anti-drop nuts; the central section of the sleeve is provided with a plurality of torsional force locking apertures used for inserting into reinforcing long rods and for stirring the sleeve for rotation. The unique features of the double force locking sleeve lie in that the front end of the sleeve bores are circular apertures located in front of the first orthohexagonal apertures and used for sleeving with the anti-drop nuts; the circular apertures shares an identical central shaft with the first orthohexagonal apertures and the diameter is equal to the size of an orthohexagonal diagonal line. The sleeve is welded with ear piers located outside the sleeve and used for hammering force application of large hammers. The double force locking sleeve has the advantages of convenience in use, a simple structure and a long centralizing distance; and moreover the double force locking sleeve is safe and reliable, and portable for use, and can increase the centralizing distance and direct bearing points as much as possible.
Description
(1) technical field
The utility model relates to the handling instrument of the beam type oil pumping machine crank tip, relates to a kind of pair of power locking sleeve.
(2) background technology
Beam pumping unit is when tight, loose crankpin locking nut and screwed retaining ring, the conventional sleeve spanner only designs in the torsion locking hole and to insert afterburning long thick stick and stir sleeve and rotate and carry out loosening, tighten of nut, but not hammering realizes tight, loose to nut, cause dynamics can't finish inadequately fastening with unclamp nut, operator can flexiblely adopt the way of inserting afterburning short thick stick and the afterburning short thick stick of weight hammering in the torsion locking hole when work high above the ground, sleeve usually occurring is flown by big hammering, the power thick stick falls, and security incident such as injures by a crashing object.Secondly, tight, the loose also instrument of neither one safety box lunch of screwed retaining ring.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, provide a kind of easy to use, simple in structure, set upright distance, safe and reliable two power locking sleeves.
The utility model is achieved by the following technical solution:
Of the present utility model pair of power locking sleeve, the front portion of sleeve endoporus is for being enclosed within the positive hexagonal hole of first on the screwed retaining ring, the sleeve middle part is provided with several and is used to insert the torsion locking hole that afterburning stock is stirred the sleeve rotation, its special character is: the front end of sleeve endoporus be positioned at the first positive hexagonal hole front be used to be enclosed within circular hole on the screwed retaining ring, the circular hole and the first positive hexagonal hole are positioned on the same central shaft and are diameter with positive hexagonal hole circumscribed circle diameter.The torsion locking hole is preferably four that are positioned on the same circle.
Of the present utility model pair of power locking sleeve, the rear portion of sleeve endoporus are to be used to be enclosed within the positive hexagonal hole of second on the locking nut.
Of the present utility model pair of power locking sleeve, be welded with on the sleeve be positioned at self the outside the ear pier that is used for the sledgehammer hammering application of force.Ear is honest preferably on the circle at torsion locking hole place and in the space between each torsion locking hole.
Described ear pier is two that are located along the same line.
The beneficial effects of the utility model are, easy to use, simple in structure, safe and reliable, light easy-to-use, in tight, the loose process of screwed retaining ring, combine the advantage of afterburning long thick stick and weight hammering to greatest extent, avoided sleeve to be flown the problem that He Ligang falls by big hammering.
(4) description of drawings
Fig. 1 looks schematic diagram for the master of this utility model.Fig. 2 is the complete section schematic diagram of Fig. 1.
Among the figure: 1 sleeve body, 2 ear piers, 3 second positive hexagonal holes, 4 first positive hexagonal holes, 5 torsion locking holes, 6 circular holes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.
Of the present utility model pair of power locking sleeve, the front portion of sleeve endoporus is for being enclosed within the positive hexagonal hole 4 of first on the screwed retaining ring, the sleeve middle part is provided with several and is used to insert the torsion locking hole 5 that afterburning stock is stirred the sleeve rotation, the front end of sleeve endoporus be positioned at the first positive hexagonal hole front be used to be enclosed within circular hole 6 on the screwed retaining ring, the circular hole and the first positive hexagonal hole are positioned on the same central shaft and are diameter with positive hexagonal hole circumscribed circle diameter.The torsion locking hole is preferably four that are positioned on the same circle.The rear portion of sleeve endoporus is to be used to be enclosed within the positive hexagonal hole 3 of second on the locking nut.Be welded with on the sleeve be positioned at self the outside the ear pier 2 that is used for the sledgehammer hammering application of force.Ear is honest preferably on the circle at torsion locking hole place and in the space between each torsion locking hole.Described ear pier 2 is two that are located along the same line.
Of the present utility model pair of power locking sleeve inserted the slotting double end that is improved to of the single head of conventional sleeve, A head (being the rear portion) dismounting locking nut, B head (promptly anterior) dismounting screwed retaining ring.And the diagonal of B the first positive hexagonal hole 4 as Circularhole diameter in the end, the lathe car advances 30 millimeters, the interior six side's thickness that keep 20 millimeters of inner ends, 30 millimeters the thickness of setting upright has just been arranged when the tense-lax screwed retaining ring like this, when guaranteeing to use sleeve dismounting screwed retaining ring, in any angle, sleeve can both insert 30 millimeters thickness at least.During the screwed retaining ring dismounting, the B end of sleeve body 1 is enclosed within on the screwed retaining ring, promptly the first positive hexagonal hole is enclosed within on the screwed retaining ring, and the circular hole 6 of its front 30 millimeters deep is enclosed within on the locking nut of screwed retaining ring front, afterburning stock is inserted torsion locking hole 5 carry out the operation of dismounting screwed retaining ring.When locking nut was installed, the second positive hexagonal hole 3 of the A of sleeve body 1 end was enclosed within locking nut, afterburning stock is inserted torsion locking hole 5 carry out fasteningly, and during the locking nut dismounting, screwed retaining ring unloads already, and this sleeve A holds and is enclosed within locking nut and unclamps.
Two firm ear piers 2 of corresponding welding between the position that keeps the interspersed afterburning long thick stick in former four holes (the about welding), in the torsion locking hole, insert long thick stick pretension and locking sleeve and nut during operation earlier, just can easily finish for four, five times with the weight hammering again the tight or loose operation of locknut.
