The specific embodiment
As shown, rod-pumped well is with the anti-eccentric wear device of rod string rotation, and pressure cap passes loam cake and is threaded with the double clutch axis, and the pressure cap ring set has a handle governor, and pressure cap and handle governor are for being threaded.The double clutch axis by internal thread with set upright the pipe be connected.Loam cake connects housing downwards.Set upright that pipe is connected with housing and both bottom flush.The outer lower portion of bidirectional clutch axis connects thrust ball bearing, bearing support, dish spring successively, and dish circlip cover is set upright pipe and is located in the housing.Double clutch is encircled down by ring and double clutch on the double clutch to be formed, on the double clutch ring and double clutch under ring set on the double clutch axis, ring-side wall is provided with two oblique slots under the double clutch, the position relative with oblique slot is provided with hole stationary balls seat on the housing, and it is interior and spacing by steel ball seat that steel ball is in oblique slot.
Be provided with two three connecting rods between ring and the loam cake on the double clutch, two three connecting rods encircle central axis and are symmetrical arranged on double clutch, and three small ends are fixed on and cover, and three connecting rod lower ends are fixed on the double clutch to be encircled.
Three connecting rods comprise fixed bar, connecting rod, pin and following fixed bar, and pin connects between last fixed bar and the connecting rod, and pin connects between connecting rod and the following fixed bar.
Be provided with sealing ring between loam cake and the pressure cap, prevent that enclosure interior fluid overflow and anti-dust storm from drenching with rain.
Set upright pipe and sealing ring is set, prevent to leak under the inner fluid with the housing junction.
The housing upper side is provided with the outstanding U-shaped projection of symmetry, in order to fixing oil pumper boom hoist cable.
Operating principle is as follows: after the utility model assembles, rod string passed from bottom to top set upright pipe, the double clutch axis is fixed on pressure cap top, the oil pumper boom hoist cable is fixed in the groove of U-shaped projection of housing both sides.When rod string is descending, be converted into from the resistance difference in the oil well that driving force drives pressure cap and double clutch moves upward, because double clutch is the restriction of two gathering sills of ring down, make to encircle under the double clutch and clockwise rotate, thereby drive double clutch axis, pressure cap, 1 set angle of rod string clockwise direction rotation, meanwhile, ring counterclockwise resets on the double clutch; When rod string is up, its gravitational difference drives pressure cap and double clutch moves downward, because the restriction of three connecting rod swing directions, impel ring clockwise direction rotation on the double clutch, and then drive double clutch axis, pressure cap, set upright pipe and rod string 1 set angle that turns clockwise, simultaneously double clutch down ring counterclockwise reset.The utility model in the process of a stroke of sucker rod, realize turning clockwise effect of 2 set angles.In addition, can also adjust the rotary speed that the distance of pressure cap upstream and downstream is regulated rod string by the rotary handle governor.
The utility model utilizes sucker rod lifting load difference to drive the utility model and realizes rod string rotation automatically, change into driving force from the resistance in the oil well when gravity of itself and sucker rod are descending when up sucker rod, double clutch and sucker rod are rotated by certain orientation, reach anti-eccentric wear, anti-breaking purpose of taking off.This device for prolonging the life-span and the pump detection period of oil pipe, sucker rod, thereby improved the overall economic efficiency that oil pumper is produced.In addition, manually actuated adjusting rotary speed of the utility model and driving direction are convenient to adapt to the variation of production status, and mobility is superior.
Superior point of the present utility model is described: one, adopt double clutch, the variation of wire rope direction of rotation is by the cooperation of the two guiding of double clutch during the oil pumper up-down stroke, and then drive being rotatably assorted of rod string, another clutch automatically resets in the time of the i.e. clutch work of the two guiding of so-called double clutch, the two minimizing mechanical loss that cooperatively interacts, the rod string rotating speed is multiplied; Two, adopt flexibly that the handle governor carries out speed governing, can significantly regulate the rotating speed of rod string and the degree of fatigue of spring; Three, pipe and spring assembly are set upright in employing, set upright pipe internal part all can be moved both vertically, and sucker rod is also played a protective role, and spring plays the effect of damping, effectively plays anti-eccentric wear, anti-sticking, cushioning effect; Four, adopt three linkages, can adjust driving direction at any time according to the operational situation of oil pumper, the efficient height, resistance to wear, mechanical loss is low; Five, the whole sealing device that adopts of the utility model, in fill lubrication oil, anti-dust storm drenches with rain, and reduces the internal part wearing and tearing.Above key technology has well prolonged the life-span and the round of visits of mining equipment, for bringing huge economic benefit in the oil field.
Should be noted that at last: above embodiment only is not intended to limit in order to the explanation the technical solution of the utility model; Although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; And not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
