Abstract

The utility model relates to a manual device that shifts of beam-pumping unit horse head, including support, chain, circular pull ring and chain block, the support welding at beam-pumping unit base front end middle part, welded a circular pull ring at the center of the lower extreme arc of beam-pumping unit horse head, be provided with a chain block below beam-pumping unit horse head, on the circular pull ring of one end string on beam-pumping unit horse head lower extreme arc of this chain block, on the support of other end system on the beam-pumping unit base. The utility model has the advantages that simple structure has practiced thrift the input of arranging mobile equipment such as crane in the well site, adjusts the position of beam-pumping unit horse head with chain block, and is safe convenient during the use.

Description

Mule-head manual displacement device of pumping unit

Technical field

The utility model relates to a kind of adjusting device of pumping unit horsehead, relates in particular to a kind of mule-head manual displacement device of pumping unit.

Background technology

The consumption of oil sharply increases in recent years, a large amount of oil pumpers is put in the production work in oil field, but the oil pumper that uses is after the well workover effect at present, the load of pumping unit horsehead suspension point is zero, at this time oil pumper is in utmost point non-equilibrium state, motor can't rotate crank body the drive pumping unit horsehead to assigned address, and the well site does not often have crane, the driving lamp lifting appliance, all to make pumping unit horsehead arrive assigned address with special equipment (as workover rig) at every turn, so not only need to be equipped with specially large-scale lifting appliances such as crane, increased to produce and dropped into, but also had certain potential safety hazard.

The utility model content

The utility model provides a kind of mule-head manual displacement device of pumping unit in order to overcome the above problems, and is simple in structure, regulates the position of pumping unit horsehead with Chain block, reduced to produce and dropped into, safe and convenient to use.

The technical solution of the utility model is: mule-head manual displacement device of pumping unit, include bearing, chain, circular draw ring and Chain block, described bearing is welded on the oil pumping unit base front center, welded a circular draw ring at the center of the lower end of pumping unit horsehead arc, below pumping unit horsehead, be provided with one and pull cucurbit, one end of this Chain block hangs on the circular draw ring on the arc of pumping unit horsehead lower end, and the other end ties up on the bearing on the oil pumping unit base.

The utility model has the advantages that: simple in structure, saved the input of arranging motor devices such as crane in the well site, regulate the position of pumping unit horsehead, safe ready during use with Chain block.

Description of drawings

Fig. 1 is a structural representation of the present utility model

1 is oil pumping unit base among the figure, the 2nd, and bearing, the 3rd, pumping unit horsehead, the 4th, circular draw ring, the 5th, Chain block, the 6th, chain.

The specific embodiment

Mule-head manual displacement device of pumping unit, include bearing 2, chain 6, circular draw ring 4 and Chain block 5, described bearing 2 is welded on oil pumping unit base 1 front center, welded a circular draw ring 4 at the center of the lower end of pumping unit horsehead 3 arc, below pumping unit horsehead 3, be provided with one and pull cucurbit 5, the size of this Chain block 5 is selected according to the weight of pumping unit horsehead 3, before oil pumper work, earlier an end of Chain block 5 is hung on the circular draw ring 4 on the pumping unit horsehead 3 lower end arcs, the other end of Chain block 5 is tied up on the bearing 2 on the oil pumping unit base 1, oil pumper is after fulfiling assignment, the load of pumping unit horsehead 3 suspension points is zero, motor can't make the crank body rotation drive pumping unit horsehead 3 and move to assigned address, at this time manually spur the chain 6 on the Chain block 5, pumping unit horsehead 3 is drawn to appointed positions, adopt this kind structure time saving and energy saving, large-scale motor devices such as crane need be set in the well site, reduced the input of cost of production, eliminated the potential safety hazard that may occur when using large-scale motor device, safety very convenient to use should vigorously promote the use.

Claims

1, mule-head manual displacement device of pumping unit, it is characterized in that: include bearing, chain, circular draw ring and Chain block, described bearing is welded on the oil pumping unit base front center, welded a circular draw ring at the center of the lower end of pumping unit horsehead arc, below pumping unit horsehead, be provided with one and pull cucurbit, one end of this Chain block hangs on the circular draw ring on the arc of pumping unit horsehead lower end, and the other end ties up on the bearing on the oil pumping unit base.
