Abstract
A gapless connector of an upper link rod joint of a pumping unit, which is used by the conventional pumping unit for oil extraction in an oil field, and consists of a crossbeam, a crossbeam support, a support gland, bolts, a lower link rod joint, a steel link rod pipe, the upper link rod joint, an upper joint rib plate and a link rod pin, wherein the crossbeam is welded on the crossbeam support, the centers of both the crossbeam support and the support gland are provided with semi-circular holes in which the link rod pin is mounted, and the link rod is mounted in the semi-circular hole of the crossbeam support, covered by the support gland and fixed by the bolts; the lower link rod joint is welded on the steel link rod pipe, the upper joint rib plate is welded on the upper end of the steel link rod pipe, the lower end of the upper link rod joint is provided with a reserved socket for the steel link rod tube and the upper joint rib plate, and the upper end of the steel link rod pipe is inserted into the lower end of the upper link rod joint and welded. The utility model resolves the following problem of the prior art: after a period of operation, a gap is formed in the connection part, as a result, noise is generated, and production is affected. The utility model can be widely used in the oil extraction operation of convenient pumping units for oil extraction in oil fields.
Description
Technical field:
The utility model relates to the oil pumper connecting rod top connection seamless connectivity device that a kind of oil field oil recovery conventional pumping unit is used.
Background technology:
Recover the oil and generally adopt beam pumping units such as conventional formula down eccentric barbell and diameter-adjusting and torque-changing in the oil field at present, and this kind oil pumper all has the shaft portion transferring power, and the connecting rod lower contact is connected by crank-pin with crank, and top connection is connected with link pin with crossbeam two ends ear seat.This mode weak point is connecting pin and ear seat hole interference fits, behind the running certain hour, because the stressed generation of extruding gap after the gap increases, abnormal noise often takes place, is unfavorable for producing.
The utility model content:
The purpose of this utility model provides a kind of oil pumper connecting rod top connection seamless connectivity device, this device solves behind the connected mode running certain hour that exists in the prior art, because the problem that abnormal noise effect is produced takes place in the stressed generation of extruding gap.
The technical scheme that its technical problem that solves the utility model adopts is: oil pumper connecting rod top connection seamless connectivity device, form by crossbeam, crossbeam bearing, bearing gland, bolt, connecting rod lower contact, connecting rod steel pipe, connecting rod top connection, top connection gusset, link pin: crossbeam and the welding of crossbeam bearing, crossbeam bearing and bearing gland center are equipped with the semicircle orifice that the load lever pin is used, and link pin are put in the semicircle orifice of crossbeam bearing and are built bearing gland bolton; Connecting rod lower contact and the welding of connecting rod steel pipe, be welded with the top connection gusset in the upper end of connecting rod steel pipe, the lower end of connecting rod top connection is provided with the preformed groove of connecting rod steel pipe and top connection gusset, and the lower end welding of the upper end of connecting rod steel pipe being injected the connecting rod top connection constitutes oil pumper connecting rod top connection seamless connectivity device.
The beneficial effects of the utility model are: simple in structure, easy to use, eliminate gap, noiselessness, and can stop the connecting rod case accident and take place, use this to install safe fault-free.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure 1, crossbeam, 2, crossbeam bearing, 3 bearing glands, 4, bolt, 5, the connecting rod lower contact, 6, the connecting rod steel pipe, 7, the connecting rod top connection, 8, the top connection gusset, 9, link pin.
The specific embodiment
In the accompanying drawings, oil pumper connecting rod top connection seamless connectivity device, form by crossbeam 1, crossbeam bearing 2, bearing gland 3, bolt 4, connecting rod lower contact 5, connecting rod steel pipe 6, connecting rod top connection 7, top connection gusset 8, link pin 9: crossbeam 1 and 2 welding of crossbeam bearing, crossbeam bearing 2 and bearing gland 3 centers are equipped with the semicircle orifice of load lever pin 9 usefulness, and it is fastening to build bearing gland 3 usefulness bolts 4 in the semicircle orifice with link pin 9 threading crossbeam bearings 2; Connecting rod lower contact and 6 welding of connecting rod steel pipe, be welded with top connection gusset 8 in the upper end of connecting rod steel pipe 6, the lower end of connecting rod top connection 7 is provided with the preformed groove of connecting rod steel pipe and top connection gusset, the lower end of connecting rod top connection 7 is injected in the upper end of connecting rod steel pipe 6, be welded into oil pumper connecting rod top connection seamless connectivity device.
