detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
By Fig. 1 composition graphs 2, Fig. 3, shown in Fig. 4 and Fig. 5, this synthetic protector for sucker rod comprises shell 1, shell 1 is built-in with butterfly spring 2, butterfly spring 2 top contacts with bottom bearing support 5, bearing support 5 soffit is connected with the outer hub of bottom freewheel clutch 4, the star-wheel of bottom freewheel clutch 4 connects Lower shaft sleeve 7, bearing 6 is installed between Lower shaft sleeve 7 and bearing support 5, Lower shaft sleeve 7 upper plane contacts with the star-wheel lower plane of top freewheel clutch 8, the outer hub of top freewheel clutch 8 extends two column types and drives bolt 14, in the oblique slot 17 driving bolt 14 periphery to be placed in shell 1 cylindrical wall is outputed, top freewheel clutch 8 star-wheel upper plane contacts with Upper shaft sleeve 10 lower flat, Upper shaft sleeve 10 top has Step Shaft and pallet 11 to be connected, step is had bottom Upper shaft sleeve 10, on step, plane contacts with the counterbore of end cap 9 lower plane, end cap 9 is connected with shell 1 bolt.
Bolt 14 is driven to be placed in oblique slot 17, when mutual alignment changes, drive bolt 14 to produce when moving up and down and can produce transverse shifting, drive the outer hub of top freewheel clutch 8 to produce to rotate, outer hub drives star-wheel to rotate, star-wheel drives Upper shaft sleeve 10 by frictional force, pallet 11 rotates and the star-wheel of bottom freewheel clutch 4 rotates, and due to the characteristic of freewheel clutch, bottom freewheel clutch 4 prevents this rotation from rotating backward.
Described Lower shaft sleeve 7 upper plane and top freewheel clutch 8 star-wheel lower flat; Described top freewheel clutch 8 star-wheel upper plane and Upper shaft sleeve 10 lower flat, often organize two planar central to have the protruding and circular counter bore of cylinder step to be connected to play centralized positioning effect, plane contact produces enough frictional force under stress makes top freewheel clutch 8 drive associated components to rotate.
Described end cap 9 top is connected with adjustment pad 12, adjustment pad 12 is between end cap 9 upper plane and pallet 11, change the thickness of adjustment pad 12, distance between pallet 11 and end cap 9 is changed, namely change the stroke of whole device, namely drive the lateral separation of bolt 14 in each stroke, thus change the anglec of rotation of each stroke, that is the rotary speed of polished rod.
Above-mentioned bottom freewheel clutch 4 bottom is connected with fairlead 3, fairlead 3 is conical shell, fairlead 3 lower housing portion diameter is greater than the circular hole at shell 1 center, when polished rod pierces into device from shell 1 bottom, can be passed from the through hole of device smoothly by fairlead 3.
All there is through hole at described each connector center, and the diameter of through hole is greater than polished rod, and the object of through hole is through polished rod and can not produces with polished rod and rubs.
Oblique slot 17 position that described shell 1 cylindrical wall is outputed, its exterior cylindrical surface is connected with dustproof sheet 13, is equipped with sliding agent in the inside of shell 1, and dustproof sheet 13 can prevent external dust from entering reduction lubricant effect.
