Abstract
A mule head of beam-pumping unit with arc-shaped flitch is used for oil extraction in oil field. Two sides of the arc-shaped horse head arc panel are respectively welded with a horse head side panel, a connecting plate is welded between the two horse head side panels, and the two horse head side panels are parallel to each other; the outer side of the horse head arc panel is welded with two arc-shaped flitch plates, the length of the two arc-shaped flitch plates is the same as that of the horse head arc panel, the inner planes of the two arc-shaped flitch plates are contacted with the outer plane of the horse head arc panel, and one side edge of the two arc-shaped flitch plates is respectively contacted with the inner side surface of the horse head side panel. The effect is as follows: the arc flitch welds on the arc surface of beam-pumping unit horse head cambered surface board, has increaseed the radius of horse head cambered surface, carries out the up-down stroke in-process at the sucker rod, can not bump between major diameter hollow polished rod and the horse head.
Description
Technical field
The utility model relates to oil field oil recovery machiner technical field, and particularly the horse head of beam pumping unit is a kind of beam pumping unit horse head that has the arc pasting board.
Background technology
Recover the oil in the oil field both at home and abroad, most of sucker rod pumping that uses.Driving sucker rod with beam pumping unit pumps crude oil is given rise to ground.Some oil fields are because oil-bearing series is many, oil reservoir is thin, so the application of layering lifting oil recovery technique just becomes the well yield of raising oil well, the main means of excavation oil reservoir potentiality.Employed hollow rod diameter is bigger in the layering lifting oil recovery technique, connects hollow polished rod on hollow rod top.And the pumping unit horsehead that beam pumping unit is arranged at present can't be fit to large diameter hollow polished rod.If in layering lifting oil recovery technique, directly use existing beam pumping unit horse head, will inevitably cause problems such as hollow polished rod misaligns, packing box leakage of oil, hollow polished rod eccentric wear, influence and use bigger hollow rod and the hollow polished rod of diameter in the layering lifting producing well.
The utility model content
The purpose of this utility model is: a kind of beam pumping unit horse head that has the arc pasting board is provided, increase the horse head cambered surface radius, so that existing beam pumping unit horse head can adapt to employed large-diameter hollow polished rod in the layering lifting oil recovery technique, solve because of existing horse head and large-diameter hollow polished rod do not match that the hollow polished rod that is caused misaligns, eccentric wear, packing box race wet goods problem.
The technical solution adopted in the utility model is: have the beam pumping unit horse head of arc pasting board, mainly be made up of horse head cambered plate, horse head side panel and pasting board; Both sides at circular arc horse head cambered plate are welded with the horse head side panel respectively, are welded with junction plate between two horse head side panels, and two horse head side panels are parallel to each other.It is characterized in that: be welded with two blocks of circular arc pasting boards in the outside of horse head cambered plate, the length of two blocks of circular arc pasting boards is identical with the length of horse head cambered plate, the inner plane of two blocks of circular arc pasting boards contacts with the outerplanar of horse head cambered plate, and a side of two blocks of circular arc pasting boards contacts with the medial surface of horse head side panel respectively.
The thickness of two blocks of circular arc pasting boards is 10mm, and width is 70mm.
Described welded seam length is 100mm, and the distance between adjacent two weld seams is 100mm.
Fixing and compacting is on the horse head cambered plate with pasting board to adopt frock, and a side of pasting board is close to the horse head side panel, carries out manual welding, and weld seam is an intermittent weld.
The beneficial effects of the utility model: the utility model has the beam pumping unit horse head of arc pasting board, the arc pasting board is welded on the arc surface of pumping unit horsehead cambered plate, strengthened the radius of horse head cambered surface, carry out can not bumping between large-diameter hollow polished rod and the horse head in the up-down stroke process at sucker rod.Solve because of existing horse head and large-diameter hollow polished rod do not match that the hollow polished rod that is caused misaligns, eccentric wear, packing box race wet goods problem.
Description of drawings
Fig. 1 is the beam pumping unit horse head structural representation that the utility model has the arc pasting board.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the A-A sectional drawing of Fig. 2.
Among the figure, 1-horse head cambered plate, 2-horse head side panel, 3-pasting board.
The specific embodiment
Embodiment 1: with a beam pumping unit horse head that has the arc pasting board is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model has the beam pumping unit horse head of arc pasting board, mainly is made up of horse head cambered plate 1, horse head side panel 2 and pasting board 3.Consult Fig. 2.Both sides at circular arc horse head cambered plate 1 are welded with horse head side panel 2 respectively, are welded with junction plate between two horse head side panels 2, and two horse head side panels 2 are parallel to each other.The length that is welded with 3, two blocks of circular arc pasting boards 3 of two blocks of circular arc pasting boards in the outside of horse head cambered plate 1 is identical with the length of horse head cambered plate 1.Consult Fig. 3.The thickness of two blocks of circular arc pasting boards 3 is 10mm, and width is 70mm.The inner plane of two blocks of circular arc pasting boards 3 contacts with the outerplanar of horse head cambered plate 1.Consult Fig. 1.One side of two blocks of circular arc pasting boards 3 contacts with the medial surface of horse head side panel 2 respectively.Adopt manual welding, fusion length is 100mm, and the distance between adjacent two weld seams is 100mm.The general structure of beam pumping unit horse head does not change, and only makes the radius of the arc surface of horse head increase 10mm.
