Abstract
An offset device for an oil-pumping unit well packing box mainly solves the problem that offset effect of an existing packing box is poor and is characterized in that a rotary sleeve (5) is connected with a packing box pressing box through threads and fixedly locked through a jack screw (6), and a nut block (2) is fixed on the upper end surface of the rotary sleeve (5). A adjustable bolt (1) is horizontally connected with the nut block (2), a right end head of the adjustable bolt (1) is rotatrily connected with a square frame block (3), and the left end surface of the square frame block (3) is connected with an offset wheel (4) through a shaft and a bearing. The offset device for the oil-pumping unit well packing box has the advantages of being good in offset effect, simple in structure and easy to operate.
Description
Technical field:
The utility model relates to the used deviation correcting device of oilfield pumping well packing box, especially rod-pumped well packing box deviation correcting device.
Background technology:
In the oil extraction in oil field field, oil pumper is the important lifting equipment in ground.In order to prevent draining between polished rod and the well head, at well head packing box is installed.And there is tuningout weak effect problem in existing packing box owing to reasons in structure, thereby causes frequent replacing packing, affects well recovery efficient, increases labor strength.
The utility model content:
In order to solve the problem of existing packing box tuningout weak effect.The utility model provides a kind of rod-pumped well packing box deviation correcting device.It is effective that this rod-pumped well packing box deviation correcting device has tuningout, structure and characteristics simple to operate.
The technical solution of the utility model is: this rod-pumped well packing box deviation correcting device comprises adjusts bolt, nut block, frame piece, tuningout wheel and rotary sleeve.Rotary sleeve is threaded connection on packing box pressing cap, and by jackscrew locking, rotary sleeve is fixed with nut block on the upper surface, adjusts bolt and laterally is connected on the nut block, adjust bolt right-hand member head and be rotatably connected to the square frame piece, frame piece left side is connected with the tuningout wheel by axle and bearing.
On the nut block external-adjuster bolt in the such scheme locking nut is arranged.
The utlity model has following beneficial effect: this rod-pumped well packing box deviation correcting device is owing to adopt rotary sleeve to be threaded connection on packing box pressing cap, and lock by jackscrew, rotary sleeve is fixed with nut block on the upper surface, adjusting bolt laterally is connected on the nut block, adjust bolt right-hand member head and be rotatably connected to the square frame piece, frame piece left side is connected with optimizing structure of tuningout wheel by axle and bearing.Utilize rotary sleeve to adjust the eccentric wear direction, recycling is adjusted bolt drive tuningout wheel and is extruded polish rod deviation regulating, thereby improves the tuningout effect, and structure and simple to operate.It is effective that this rod-pumped well packing box deviation correcting device has tuningout thus, structure and characteristics simple to operate.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is Fig. 1 top views.
1-adjusts bolt among the figure, 2-nut block, 3-frame piece, 4-tuningout wheel, 5-rotary sleeve, 6-jackscrew, 7-locking nut.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in the figure, this rod-pumped well packing box deviation correcting device comprises adjustment bolt 1, nut block 2, frame piece 3, tuningout wheel 4 and rotary sleeve 5.Rotary sleeve 5 is threaded connection on packing box pressing cap, and by jackscrew 6 lockings, by the direction that extrudes of rotary sleeve 5 adjustment tuningout wheels 4, polished rod is inclined to one side thereto, and tuningout wheel 4 just rotates to over there by rotary sleeve 5.Rotary sleeve is fixed with nut block 2 on 5 upper surfaces, adjusts bolt 1 and laterally is connected on the nut block 2, makes tuningout wheel 4 produce displacements by nut block 2 and adjustment bolt 1 and extrudes polished rod.On the nut block 2 external-adjuster bolts 1 locking nut 7 is arranged, adjust bolt 1 by locking nut 7 lockings, prevent from becoming flexible, adjust bolt 1 right-hand member head and be rotatably connected to square frame piece 3, frame piece 3 left sides are connected with tuningout wheel 4 by axle and bearing, and by frame piece 3 connecting axles, bearing and tuningout wheel 4, frame piece 3 can only move left and right and can not rotate, by bearing tuningout wheel 4 can be rotated freely, and then reduce the friction of tuningout wheel 4 and polished rod.
Operation principle:
This rod-pumped well packing box deviation correcting device is connected on the packing box pressing cap by rotary sleeve 5.During adjustment, at first find polished rod eccentric wear direction accurately, then tuningout wheel 4 is adjusted to the polished rod eccentric wear over there, by jackscrew rotary sleeve 5 is locked after aiming at, rotation is adjusted bolt 1 and is extruded polished rod again, makes polished rod be positioned at the packing box center, adjust bolt 1 with locking nut 7 lockings at last, namely finish the tuningout operation.
Claims (2)
