Abstract
The utility model relates to a split type adjustable weight used in oil production and lifting equipment of oil fields. The weight of the utility model comprises a main weight and an auxiliary weight, wherein the main weight and the auxiliary weight are fixed by a connecting strip and a pin shaft which are fixed on the weight; the main weight is mainly composed of a weight box and guide rope pulley sets fixed at the two sides of the weight box, and each guide rope pulley in the guide rope pulley sets is guided by the guide rope fixed on a tower. The split type adjustable weight provided by the utility model has the following advantages that the installation is convenient, the adjustment is simple and convenient, the operation is smooth, the weight can be increased and decreased as needed and the best balance effect can be realized.
Description
Technical field
The utility model relates to the accessory in a kind of oil extraction in oil field lifting equipment, applies to specifically play on the tower shelf type oil pumping machine of oil field the split type adjustable weight of balanced action.
Background technique
Individual well tower shelf type oil pumping machine and a machine twin-well tower shelf type oil pumping machine all need counterweight, and counterweight is positioned at pylon, and to pumping unit, steady effect is played in operation.During tower shelf type oil pumping machine work, steel wire rope or belt one end connects lifting sucker rod, and one end connects counterweight, and counterweight realizes and pumping via upper saw pulley.Because pumping unit is operated in field, pylon road clearance size is larger, and counterweight wind-engaging carries impact greatly, counterweight is constantly vibrated and is even rocked in upper and lower working procedure, accelerate structural member wearing and tearing, reduce service life of steel wire rope, disconnected rope even occurs and fall well security incident.And traditional counterweight adopts cement and packing to mix to build to form, monoblock counterweight cannot be according to hole condition load control balancer weight.And wire rope in use, length cannot regulate, and uses after a period of time, and the deformation meeting that wire rope occurs causes counterweight run-off the straight, causes peril when serious.
Model utility content
In order to address the above problem, the utility model provides a kind of split type adjustable weight.That this adjustable weight has is easy for installation, it is easy to regulate, operate steadily, and can to counterweight, can increase and can subtract, realize optimum balance effect as required.
The technical solution of the utility model is: a kind of split type adjustable weight, comprise main counterweight and secondary counterweight, and described main counterweight and secondary counterweight are fixed by the connection strap and the bearing pin that are fixed in counterweight; Described main counterweight is comprised of ballast box and the conductor rope wheels that are fixed on ballast box both sides, and each rope-guiding wheel in conductor rope wheels is led by the conductor rope being fixed on pylon.
Above-mentioned main counterweight is suspended to the lower end of wire rope, and wire line thimble is on the cylinder of pumping unit.
One end of above-mentioned wire rope is directly connected with main counterweight, and the other end is to be connected with main counterweight by turn-bucklet.
In above-mentioned main counterweight, be fixed with suspension ring.
The beneficial effects of the utility model are: in such scheme, adopt split type adjustable weight structure, counterweight is divided into main counterweight and secondary counterweight two-part, by turn-bucklet structure being set and in main counterweight both sides, rope-guiding wheel being set, the rope-guiding wheel in main counterweight moves along the conductor rope being fixed on pylon.That this split type adjustable weight has is easy for installation, it is easy to regulate, operate steadily, and can to counterweight, can increase and can subtract, realize optimum balance effect as required.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of main counterweight in Fig. 1;
Fig. 3 is the side view of main counterweight shown in Fig. 2.
The main counterweight of 1-in figure, the secondary counterweight of 2-, 3-connection strap, 4-bearing pin, 5-conductor rope, 6-rope-guiding wheel, 7-counterweight conductor rope wheels, 8-ballast box, 9-suspension ring, 10-turn-bucklet, 11-wire rope.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
By shown in Fig. 1 to Fig. 3, this split type adjustable weight comprises main counterweight 1 and secondary counterweight 2, described main counterweight 1 is fixedly connected with bar 3 with the edge of secondary counterweight 2, two connection straps 3 are connected and are fixed by bearing pin 4, as shown in Fig. 1, by connection strap 3 and bearing pin 4, connect and take apart, realize the combination of main counterweight 1 and secondary counterweight 2 with separated, while applying to individual well tower shelf type oil pumping machine, main counterweight and secondary counterweight two-part are used simultaneously; While applying to twin-well oil-pumping machine, only use main counterweight, thereby reach the effect that regulates counterweight; Above-mentioned main counterweight 1 is mainly comprised of ballast box 8 and the conductor rope wheels 7 that are fixed on ballast box both sides, conductor rope wheels 7 comprise some rope-guiding wheels 6, each rope-guiding wheel 6 is by conductor rope 5 guiding that are fixed on pylon, and wherein, conductor rope 5 is positioned at the groove of rope-guiding wheel, conductor rope 5 is fixed on pylon, during work, when counterweight is moved up and down, the rope-guiding wheel in main counterweight moves along the conductor rope being fixed on pylon, prevent that counterweight from rocking, kept the stable of counterweight integral body.
Above-mentioned main counterweight 1 is suspended to the lower end of wire rope 11, and wire rope 11 is looped around on the head roll of pumping unit; In order to adjust the center of gravity of counterweight, one end of wire rope 11 is directly connected with counterweight, and the other end is to be connected with main counterweight 1 by turn-bucklet 10, when there is skew in counterweight center of gravity, can change the length of turn-bucklet by twisting turn-bucklet 10, make counterweight in equilibrium position.
In addition, in above-mentioned main counterweight 1, be fixed with suspension ring 9, suspension ring 9, when installing and keep in repair, can directly be lifted on counterweight on pylon platform, make it with cylinder in disengaged position.
The remaining larger space of main counterweight 1 inner chamber, can fill weight, according to need of work, by increasing and decreasing the filling weight in main counterweight, realizes optimum balance effect.
