Abstract
The utility model discloses an oscillating fixed pulley rope winding jib. The fixed pulley of the oscillating pulley mechanism is fixed on the movable disk, and is fixed on the bracket through a rotation bearing and a static disk. The fixed pulley can swing a certain degree relative to the perpendicular bisector of the roller body rope-holding groove. The winch assembly is fixed on the frame and it consists of a roller body, a transmission wheel, a brake rim and a rotary shaft, wherein the rotary shaft is fixed on the winch base through the bearing seat; the roller body nests on the rotary shaft. The other end is provided with the transmission wheel and the brake rim and can connect with the actuating unit and the brake device. The wire rope wraps around the roller body through the fixed pulley of the oscillating pulley mechanism; it drives the fixed pulley of the oscillating pulley mechanism to swing by the lateral force created during the rope-arrangement process or by adding a small external force, realizing the equal rope-arrangement function of the wire rope on the roller body.
Description
Technical field
The utility model provides a kind of swing type fixed pulley rope guide, relates to the winch rope-discharging mechanism on the bailing equipment in the oil field, belongs to lifting, weight-lifting equipment physical construction technical field.
Background technology
In oil production, from sleeve pipe or oil pipe, drive plug bailing suction crude oil with steel rope, be the new process measure of just having adopted in recent years; The winch that drilling well originally and well workover are used, used steel rope has only more than 200 meter, and be adapt to the used steel rope of bailing suction operation technique at least should be at 500～600 meters, even reach 2000 meters, rope capacity should be complementary with oil well depth.According to mechanics principle, when the winch drum lay winding wire ropes, no matter move to the left or to the right, the recurrence center component that a Yin Lali is all arranged and produce, make winch can not normally arrange rope, therefore, existing winch usually adopts the forced rope method when lay winding wire ropes, on the steel rope between sheave and the winch, apply forced rope power, to guarantee row's rope in order, but steel rope is stressed bigger like this, and the wearing and tearing of rope-arranging mechanism and steel rope strengthen, and service life and reliability reduce, equipment cost improves, and directly has influence on bailing oil work production.
Summary of the invention
The utility model discloses a kind of swing type fixed pulley rope-discharging method, the shortcoming that the resistance that has overcome existing mandatory rope guide is big, power consumption is big.
For achieving the above object, concrete solution is as follows: be made of winch assembly, swing pulley mechanism and support and steel rope, the fixed pulley of swing pulley mechanism is fixed on the Moving plate, rack-mount by rolling bearing, quiet dish, fixed pulley can be swung certain angle with respect to barrel rope slot perpendicular bisector; The winch assembly is fixed on the support, is made of barrel, power wheel, brake hubs and turning cylinder, wherein, turning cylinder is fixed on the winch base by bearing seat, the barrel suit is on it, and the other end is provided with power wheel and brake hubs, can be connected with brake gear with the engine ditch; Steel rope is wrapped on the barrel by the fixed pulley of swing pulley mechanism, by the fixed pulley swing that the side force that produces in row's rope process or an additional very little external force drive the swing pulley mechanism, and the even row of realization steel rope on the barrel function of restricting.
Good effect of the present utility model is: swing pulley mechanism and barrel formation relatively rotate pair, finish relatively rotating of the two by side force or additional very little external force of producing in the rope woolding process, avoided the forced rope device that applies at steel rope middle part, eliminated forced rope power, the wearing and tearing of steel rope and the kinetic equation loss of equipment have been reduced, prolong the service life of steel rope, reduced equipment cost, improved the work efficiency of bailing oil.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.Fig. 2 is the leading sheave constructional drawing.
The specific embodiment
According to Fig. 2, fixed pulley 1 installs on pulley yoke 3 by sheave shaft 2 in the swing pulley mechanism, the bottom of pulley yoke 3 is relatively turnable Moving plate 5 and quiet dish 7, be provided with inner slide and external slideway between Moving plate 5 and the quiet dish 7, be inlaid with bearing 4,6 respectively, quiet dish 7 is fixedly mounted on the support 9, and support 9 is installed on the support 10, and Moving plate 5 and fixed pulley 1 can be swung along slideway; Among Fig. 1, on support 10, also be fixed with winch assembly 11, in winch assembly 11, barrel 13 is fixed on the winch base 12 by transmission shaft 15, end at transmission shaft 15 is provided with brake drum 14 and power wheel 16, be connected with actuating unit, brake gear respectively, steel rope 8 is wrapped on the barrel 13 by fixed pulley 1, start actuating unit and drive power wheel 16,13 rotations of transmission shaft 15 drive barrels, realize the winding of steel rope 8, under a lay winding wire ropes side force or an additional very little external force effect, make fixed pulley 1 swing, finish the even row action of restricting.
