Abstract
The utility model relates to a write off is protected and is detained quick dismounting device. The problem that the in -process easily led to the fact crank pin screw and the interior terminal surface damage of round pin axle is dismantled to the main crank of pumping unit round pin that has now of solving. Its characterized in that: main part (1) right -hand member internal thread connects hammering piece (2), and main part (1) left end external connection has eight claw elasticity cards (10), and left end protrusion in main part (1) the terminal surface of eight claw elasticity cards (10), eight claw elasticity card (10) external connections have staple bolt (3), are connected with between two ends of staple bolt (3) tie bolt (8). Adopting this write off is protected and is detained quick dismounting device, can protecting crank pin screw thread and round pin axle head face when dismantling the crank pin, protective apparatus does not damage, realizes the adjustment of beam -pumping unit stroke.
Description
Technical field
This utility model relates to oilfield, and button quick-release arrangement is protected in a kind of write off.
Background technology
In oilfield process, oil pumper needs when changing crank-pin or adjusting stroke to dismantle crank-pin, at this moment need to use sledgehammer that crank-pin impacts out stroke hole, in the process, easily cause crank-pin screw thread and the damage of bearing pin inner face, affect oil pumper and adjust ginseng operation and cause device damage.Current crank-pin dismounting difficulty, it is easily damaged reason essentially from two aspects: 1, crank-pin coordinates tighter with guide: for taper fit between Crank Pin on Pumping Units and guide, crank, owing to taper fit has latching characteristics, in addition in running, nut fastening dynamics is bigger, life-time service easily causes tarnish resistance locking, thus the most difficult when secondary is dismantled；2, paddle type mill removing method is relatively easy to damage crank-pin: owing to crank-pin is installed relatively tight, during secondary dismounting, majority uses the mode of hammering to take out, but during the flat side of a hammer collides with crank-pin, inevitably results in crank-pin end face and screw thread damage.
Summary of the invention
In order to easily cause crank-pin screw thread and the deficiency of bearing pin inner face damage during overcoming existing detaching crank pin of cooker hood; this utility model provides a kind of write off to protect button quick-release arrangement; this write off is used to protect button quick-release arrangement; crank-pin screw thread and pin roll end face can be protected when dismantling crank-pin; protection equipment does not damages, it is achieved oil pumper stroke adjusts.
The technical solution of the utility model is: button quick-release arrangement is protected in a kind of write off, including cylindrical main body, described main body right-hand member internal whorl connects hammering block, main body left end is externally connected to eight pawl elastic cards, and eight the left end of pawl elastic card protrude from main body end face, described eight pawl elastic cards are externally connected to anchor ear, and connecting between two terminations of anchor ear has turnbuckle.
It is inlaid with three-jaw conversion sleeve inside described eight pawl elastic card left ends.
Described turnbuckle one end connects adjusting nut, and the other end connects eccentric handle by wearing pin bolt, and the outside of turnbuckle is provided with cushion block, and cushion block is placed between anchor ear termination and eccentric handle.
This utility model has the advantages that owing to taking such scheme; this device is stuck on crank-pin screw thread by eight pawl elastic cards or three-jaw conversion sleeve; and existing hammering direct to crank-pin is converted to by hammering block indirection hammering; on the one hand the damage of crank-pin screw thread is avoided; on the other hand crank-pin facet damage is also avoided; thus ensure in crank-pin unloading process safe and reliable, to greatest extent crank-pin is formed effectively protection simultaneously.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is left view of the present utility model.
1-main body in figure, 2-hammering block, 3-anchor ear, 4-eccentric handle, 5-conversion sleeve, 6-wears pin bolt, 7-cushion block, 8-turnbuckle, 9-adjusting nut, 10-eight pawl card.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
Shown in Fig. 1, Fig. 2, button quick-release arrangement is protected in a kind of write off, and including cylindrical main body 1, main body 1 left end is entity, and right-hand member internal whorl connects hammering block 2.Main body 1 left end is externally connected to eight pawl elastic cards 10, has groove outside main body 1 left end, and a part for eight pawl elastic cards 10 is embedded in groove, and the left end of eight pawl elastic cards 10 protrudes from main body 1 end face.Described eight pawl elastic cards 10 are externally connected to anchor ear 3, connect between two terminations of anchor ear 3 and have turnbuckle 8, described turnbuckle 8 one end connects adjusting nut 9, the other end connects eccentric handle 4 by wearing pin bolt 6, and the outside of turnbuckle 8 is provided with cushion block 7, cushion block 7 is placed between anchor ear 3 termination and eccentric handle 4.Anchor ear 3 can be made to hold tightly by tightening adjusting nut 9, be rotated further by eccentric handle 4 and can strain anchor ear 3 further by cushion block 7 and turnbuckle 8, make eight pawl elastic cards 10 clamp further.Can inlay three-jaw conversion sleeve 5 inside described eight pawl elastic card 10 left ends, the internal diameter of three-jaw conversion sleeve 5 is less than eight pawl elastic cards 10, so that it goes for the crank-pin of minor diameter.
When dismantling crank-pin, eight pawl elastic cards 10 being inserted in crank-pin screw thread, adjust the adjusting nut 9 of turnbuckle 8 one end, make that anchor ear 3 is micro-to be held tightly, then move eccentric handle 4, tension anchor ear 3 further, so that eight pawl elastic cards 10 hold crank-pin tightly.Then use sledgehammer hammering device afterbody hammering block 2, crank-pin is taken out.If run into small diameter crank-pin, inside eight pawls of conversion sleeve 5 embedding device, it is contained on crank-pin after reducing inside diameter, is being taken out by hammering.When hammering block 2 is after impact repeatedly deforms breakage, deformation, can individually it be replaced, it is ensured that the Reusability of device.The protection to crank-pin in operation by this device, and its hammering brought plays maximum force, thus ensure adjustment process be smoothed out and efficiency improves, to greatest extent crank-pin is formed effectively protection simultaneously.
