Abstract
A crank-detaching tool for a pumping unit is composed of a support part and a drawing part, which is characterized in that the support part is provided with an n-shaped frame, a round central hole is provided in the center of the cross beam of the n-shaped frame, a steel jacket is inserted into the central hole with the upper diameter larger than the diameter of the central hole and the lower diameter smaller than the diameter of the central hole, the lower end of the steel jacket is provided with left-hand external thread in cooperation with a left-hand locknut, both of which are positioned by a positioning lock, and the steel jacket is limited in the central hole of the cross beam to rotate; the drawing part is provided with a central shaft with external thread in cooperation with the steel jacket whose inner diameter is provided with internal thread, and the bottom end of the central shaft is welded together with a drawing machine which is composed of a lateral beam, two drawing jaws sliding on the two ends of the lateral beam, a pull rod provided with external thread and between the two drawing jaws, and a tightening bidirectional nut screwed on the pull rod. The tool draws off a crank pin quickly, saving time and labor.
Description
One, technical field
The utility model is a kind of Crank Pin on Pumping Units puller that is used for pulling up when oil pumper is transferred stroke crank-pin or replacing crank-pin.
Two, background technology
In field produces, for pumpingh well, in order to satisfy the field produces needs, change the manufacturing parameter of rod-pumped well, improve crude output, transferring the length of stroke is regular work, and transferring length of stroke is to realize by the position, hole of removable crank pin on crank.Because of the oil pumper load is heavier, generally at the 3-12 ton, this heavy load is all transmitted by the crank-pin carrying and is finished, and crank-pin is to be in the same place by tapering or key connecting with crank hole, and tightens crown nut and be equipped with cap in the end.When transferring stroke, will be equipped with cap earlier and crown nut unloads, with the direct hammering of sledgehammer, pin is pounded out, because the pin tension often smashes the pin screw thread, pin smashes and also needs more to renew, and pounds will slicing off with cutter of not coming out.Beat also danger close of sledgehammer on oil pumping unit base, work and operating personnel's trick also are ordinary affair.And the method for operating of this clumsiness, cause the oil well off-time long, rate when influence is produced.
Three, summary of the invention
The purpose of this utility model provides a kind of Crank Pin on Pumping Units puller, makes saving of labor when transferring stroke, saves time, safety, reduces oil well and stops the well time, rate when improving oil well production.
The technical solution of the utility model realizes in the following manner:
The utility model is by supporting part and pull up part and form, it is characterized in that supporting part is provided with n shape support, transoms center at n shape support is provided with round center hole, upper diameter is greater than center-hole diameter, insert in its centre bore less than the steel bushing of center-hole diameter the bottom, the steel bushing lower end is provided with that the left-hand thread external screw thread cooperates with the left-hand thread locknut and both locking bits that are positioned, and rotates in the transoms centre bore steel bushing is spacing; Pull up partly to be provided with and have externally threaded central shaft, the steel bushing that is provided with internal thread with internal diameter cooperates, the bottom of central shaft and by crossbeam, at the crossbeam two ends slidable two pusher dogs, between two pusher dogs, be provided with externally threaded pull bar and be screwed in the office that pulls up that the two-way nut of tension on the pull bar forms and weld together.
Steel bushing top is provided with hexagon, and use matches with custom-designed Hexagonal jacket spanner.
The upper surface, center of central shaft bottom and crossbeam welds together.
The pusher dog lower end is provided with eave tile and is 90 degree, and the eave tile position is provided with the anti-slip tank of indention.
The utility model is used to transfer stroke, shortened to half an hour by one hour original time spent, and prevented the crank-pin damage, the economical with materials expense, safe and reliable, alleviated working strength of workers, thereby rate when having improved oil well production has increased crude output, is the ideal tools that oil pumper is transferred stroke, filled up this blank in the field production management, had excellent popularization and be worth.
Four, description of drawings

Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is by supporting part and pull up part and form, it is characterized in that supporting part is provided with n shape support, transoms center at n shape support is provided with round center hole, upper diameter is greater than center-hole diameter, insert in its centre bore less than the steel bushing of center-hole diameter the bottom, the steel bushing lower end is provided with that the left-hand thread external screw thread cooperates with the left-hand thread locknut and both locking bits that are positioned, and rotates in the transoms centre bore steel bushing is spacing; Pull up partly to be provided with and have externally threaded central shaft, the steel bushing that is provided with internal thread with internal diameter cooperates, the bottom of central shaft and by crossbeam, at the crossbeam two ends slidable two pusher dogs, between two pusher dogs, be provided with externally threaded pull bar and be screwed in the office that pulls up that the two-way nut of tension on the pull bar forms and weld together.
