Beneficial technical effects of the present utility model is: two mouthfuls of wells are only used a motor, owing to adopted the rope traction mechanism of fixed pulley and movable pulley combination, the wire rope of two oil pumpers oppositely twines mutually, form two oil pumpers structure of counterweight each other, greatly reduced the power of oil pumper.For example with respect to horse head formula or tower-type pumping unit, power of motor can be reduced to a 22KW by two original 40KW.Like this, two oil pumpers just can reduce by a motor, and the coupling of power has become a present motor 22KW by two original motor 80KW, and its energy conservation and consumption reduction effects is conspicuous.And, when a bite oil well overhauls, horse head can be removed from angle of well head rotation, in the end assembling preparation counterweight of wire rope, then the corresponding oil pumper of another horse head still can operate as normal.

Description of drawings

Accompanying drawing 1 is a structural representation view of the present utility model, and accompanying drawing 2 is vertical views of accompanying drawing 1, and the dotted line in the accompanying drawing 2 represents that horse head can move in arbitrarily angled rotation.Because and goal of the invention of the present utility model is far, therefore, supporting facility such as the cat ladder of the frame of not drawing in the accompanying drawing, guardrail.Sequence number in the accompanying drawings is described as: 1, frame, 2, hoist engine, 3, the preparation counterweight, 4, movable pulley, 5,6,7,9, fixed pulley, 8, movable pulley, 10, draw bar, 11,12, steel cable termina, 13,14, wire rope.

The specific embodiment

Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this twin-well oil-pumping machine, has frame [1], hoist engine [2] is installed on the base below frame, have two groups of fixed pulleys [6] and [7] and [5] and [[9] on the top of frame [1], wire rope [13] is fixed in a side of frame by steel cable termina [11], through movable pulley [8] to fixed pulley [7] and [6] break-in, be wound on reel one end of hoist engine [2], another group wire rope [14] is fixed in the opposite side of frame by steel cable termina [11], to fixed pulley [9] and [5] break-in, oppositely be wound on the other end of the reel of hoist engine [2] through movable pulley [4], on frame [1], fix a demountable preparation counterweight [3].Shown in the dotted line in the accompanying drawing 2, the horse head assembly of fixed pulley [5] and [9] and support fixed pulley [9] can be around the axis centre rotation of fixed pulley [5] with the wire rope [13] of a side of lifting drum.Similarly the horse head assembly of fixed pulley [6] and [7] and support fixed pulley [7] can be around the axis centre rotation of fixed pulley [6] with the wire rope [13] of a side of lifting drum
