Abstract
A crank pin screw cap assembling and disassembling device for an oil pumping machine comprises a blocking cap, adjustment springs, adjustment bolts, a strengthening sleeve, a socket wrench and a handle, wherein the handle is fixed on the socket wrench, the strengthening sleeve is provided with an internal thread, a plurality of adjustment bolts evenly penetrates through the right end of the strengthening sleeve, the adjustment springs on the right side of a right end plate of the straightening sleeve are sleeved on the adjustment bolts, and left ends of the adjustment bolts are connected with the blocking cap positioned on the left side of the right end plate of the straightening plate. The right ends of the adjustment bolts contact the left end of the socket wrench, and the straightening sleeve provided with the internal thread can be screwed on an external thread of a crank pin. The straightening sleeve and the crank pin are coaxial, thereby avoiding vibration and movement. The adjustment bolts cannot vibrate and move. The adjustment bolts contact the left end of the socket wrench, thereby liming the socket wrench. Because the adjustment bolts cannot vibrate and move, the socket wrench cannot drop. The crank pin screw cap assembling and disassembling device can achieve the design aim of dismounting the screw cap of the fixed crank pin conveniently.
Description
Technical field
The utility model is a kind of instrument of oil field installation and maintenance oil pumper, is a kind of oil pumping machine crank pin nut handler.
Background technology
The crank of oil pumper connects by crank pins with connecting rod, crank pins by fixed by nut on crank, when oil pumper need be adjusted running parameter or during the crank pins that change to damage; Need crank pins be taken apart from the pin-and-hole of crank, oil pumper is in the long-term work process, because crank pins produces corrosion, distortion; Make the nut of its fixed crank pin be difficult to dismounting, need beat the box spanner that dismounting handle pin uses with iron hammer and could nut be unloaded pine, when beaing box spanner with iron hammer; Vibration causes that easily box spanner comes off, and the operator is abnormally dangerous, often can not accomplish oil pumper adjustment running parameter and the work of changing the crank pins that damages; Influence job schedule, the load affair time, cause personal injury easily; Need take a long time, the manpower of input is also many.
Summary of the invention
The purpose of the utility model is a kind of oil pumping machine crank pin nut handler of design, can be easily the nut of fixed crank pin be disassembled.
The purpose of the utility model has been achieved in that box spanner, handle, and handle is fixed on the box spanner, keeps off cap, regulating spring, adjusting bolt, supporting positive cover in addition; Set upright and be with internal thread, evenly penetrate several on the supporting positive cover right end plate and regulate bolt, regulate suit regulating spring on the bolt; Regulating spring is in supporting positive cover right end plate right side; Regulate the bolt left end and connect the retaining cap, the retaining cap is in supporting positive cover right end plate left side, regulates the left end that the bolt right-hand member can the contact sleeve spanner.
The beneficial effect of the utility model is: sets upright and is with internal thread, can be screwed on the external screw thread of crank pins, so; Supporting positive cover is coaxial with crank pins, can not vibrate and move, and regulates bolt and also can not vibrate and move; After regulating bolt and the left end of box spanner contacting, can limit box spanner, also can not vibrate and move owing to regulate bolt; So box spanner can not come off; Therefore, the utility model can reach purpose of design, can be easily the nut of fixed crank pin be disassembled.
Description of drawings
Accompanying drawing 1 is the installation diagram of the utility model embodiment.
The specific embodiment
1 couple of the utility model embodiment describes below in conjunction with accompanying drawing.
Can know by figure; The embodiment of the utility model has retaining cap 1, regulating spring 2, regulates bolt 3, supporting positive cover 4, box spanner 5, handle 6, and handle 6 is fixed on the box spanner 5, and supporting positive cover 4 has internal thread 7; Evenly penetrate several on supporting positive cover 4 right end plate and regulate bolt 3; Regulate suit regulating spring 2 on the bolt 3, regulating spring 2 is in supporting positive cover 4 right end plate right sides, regulates bolt 3 left ends and connects retaining cap 1; Retaining cap 1 is in supporting positive cover 4 right end plate left sides, regulates the left end that bolt 3 right-hand members can contact sleeve spanner 5.
