Abstract
The utility model relates to a special disassembly and assembly pull tube for a crank bushing of a beam pumping unit. A supporting sleeve (2) is coaxially connected with a threaded pull rod (3) in a penetrating way, and an opening is arranged at the center of the upper end of the supporting sleeve; the lower end of the supporting sleeve (2) is opened, and the upper end of the threaded pull rod (3) penetrating through the supporting sleeve (2) is screwed with a movable nut (1); and the lower end of the threaded pull rod (3) is screwed with a fixed nut (4), and a pull piece (5) with a U-shaped groove is clamped beside the fixed nut (4). The supporting sleeve and the threaded pull rod are matched to prolong the axial acting force arm to be used as the special disassembly and assembly tool, which has a simple structure and strong adaptability and is convenient to use. The damage or deformation of the bushing caused by knocking the crank bushing with a hammer in the prior art is avoided, and the site construction is convenient, safe and efficient.
Description
Technical field
The utility model relates to maintenance tool technology or device in the beam pumping unit operation, especially the special-purpose dismounting trombone slide of beam type oil pumping machine crank lining.
Background technology
In the prior art, beam pumping unit is used more extensive in oil field operation.Beam pumping unit also claims girder-like oil pump, beam type crank balanced pumping unit, refers to contain walking beam, and by the linkage commutation, the oil pumper of crank pouring weight balance is commonly called as the machine of kowtowing.Beam pumping unit from oil production method for bar class oil production equipment is arranged.When beam pumping unit was worked, the transmission of motor became moving up and down of horse head through gearbox, toggle, and horse head moves up and down through the plunger that polished rod, sucker rod drive the down-hole deep well pump, thereby constantly the crude oil in the well is extracted out pit shaft.
The oil pumper of at present oil field use, the variation of base area stressor layer, liquid level, oil pressure and oil well are repaired by the jig frequency and the stroke that often need to adjust oil pumper, to guarantee stable and high yields and the long period of development of oil well, beam pumping unit is adjusted parameter and is belonged to handwork, labour intensity is large, and the crank lining to adjust the distance to about 1.5 meters of cement bases, cement base basic horizontal position just can remove and install.When originally changing the crank lining, the method for the parallels that hits with a hammer is taken out the crank lining, not only wastes time and energy but also fragile crank lining, and its handwork labour intensity is large.
Summary of the invention
Goal of the invention of the present utility model provides the special-purpose dismounting trombone slide of a kind of beam type oil pumping machine crank lining, and this installs as specific purpose tool, with crank lining for convenience detach.
The purpose of this utility model will realize by following technical measures: supporting sleeve upper end center drilling, the supporting sleeve lower end is open, the coaxial cross-under thread of supporting sleeve, the activity nut spins on thread passes supporting sleeve, the thread lower end hold-doun nut that spins, the pulling force sheet that has U-lag is connected to by the hold-doun nut.
Advantage of the present utility model and effect: simple for structure as the special dismounting installation special tool, easy to use by cooperating extending shaft to acting force arm with supporting sleeve and thread, strong adaptability.Avoid hitting with a hammer the crank lining in the prior art and cause lining to damage or distortion, convenient during site operation, safe, efficiently.
Description of drawings
Fig. 1 and Fig. 2 are the dismounting of embodiment 1 in the utility model and the structural representation when installing.
Reference numeral comprises: movable nut 1, supporting sleeve 2, thread 3, hold-doun nut 4, pulling force sheet 5.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Supporting sleeve 2 upper end center drillings, supporting sleeve 2 lower ends are open, and supporting sleeve 2 coaxial cross-under threads 3 pass the supporting sleeve 2 upper ends activity nut 1 that spins at thread 3, thread 3 lower ends spin, and the pulling force sheet 5 that has U-lag is connected to hold-doun nut 4 sides.
In the utility model, the steel pipe that cut lengths are suitable is regarded supporting sleeve 2, again a round plate with diameter is welded on the bottom of supporting sleeve 2 as stress surface, open a circular hole at its bottom centre place, the circular hole of thread 3 from bottom centre passed, install a movable nut 1 in the rear end of thread 3 additional, install a hold-doun nut 4 additional at the front end of thread 3; With steel plate make three different-diameters with the disk of U-lag as pulling force sheet 5, be used as dismounting and the push-pull piece of crank lining be installed.
The utility model using method comprises:
Beam type oil pumping machine crank is stopped at horizontal level, inserts the support bar of beam pumping unit in the hanger and be screwed; During dismounting crank lining as shown in Figure 1, suitable pulling force sheet 5 is attached to the crank lining inboard, thread 3 is passed pulling force sheet 5 and crank hole, make its hold-doun nut 4 compress pulling force sheet 5, be enclosed within supporting sleeve 2 on the thread 3 and make its openend be buckled in the crank lining outside, movable nut 1 is screwed in thread 3 ends, after adjusting pulling force sheet 5 and crank lining position, screw in the direction of the clock movable nut 1 (six square nuts) with double offset ring spanner, leave crank hole fully to straight crank lining and fall into supporting sleeve 2; When the crank lining is installed as shown in Figure 2, the crank lining is aimed at crank hole, suitable pulling force sheet 5 is attached to the lining outside, nut pull bar 3 is passed pulling force sheet 5, crank lining and crank hole, make its hold-doun nut 4 compress pulling force sheet 5, be enclosed within supporting sleeve 2 on the thread 3 and to make its openend be buckled in the crank lining inboard, movable nut 1 is screwed in thread 3 ends, adjust the position of nut pull bar 3 and pulling force sheet 5, screw in the direction of the clock movable nut 1 six square nuts with double offset ring spanner, make the crank lining be inserted in crank hole fully.
Advantage of the present utility model comprises: avoids hitting with a hammer the crank lining and causes lining to damage or distortion, and convenient during site operation, safe, efficiently.
