Abstract

The invention relates to the technical field of oil pumping units, and discloses an oil pumping unit for oil extraction. The oil pumping unit comprises a base, a groove chamber is formed in the left side of the upper surface of the base, a second movable groove is arranged in an inner cavity of the groove chamber, speed reducing pieces are movably arranged in an inner cavity of the second movablegroove, a speed reducing mechanism is fixedly arranged above the groove chamber, and linkage rods are fixedly connected to the two sides of the top of the speed reducing mechanism. Balance weights arefixedly installed on the two sides of the two linkage rods, and first movable grooves are formed in the inner sides of the balance weights. By utilizing the structure of the speed reducing pieces, aclamping groove, the first movable grooves and the second movable groove, when the device is in use, the deceleration effect can be achieved through transition of tracks and butt connection of the multiple speed reducing pieces and the interiors of the tracks in the working process, abrasion caused by gravity to equipment when the device descends is reduced, therefore, the abrasion speed of the equipment in the using process is delayed, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of oil pumping units, in particular to an oil pumping unit for oil production. Background technique [0002] Beam pumping unit, also known as beam pumping unit and beam pumping unit with crank balance, refers to a pumping unit that contains a beam, reverses direction through a connecting rod mechanism, and balances crank weights, commonly known as a kowtow machine. [0003] The balance of the donkey head part of the existing pumping unit is poor during use, which leads to the fact that the bottom of the rope hanger cannot be perfectly docked with the pumping well during use, resulting in serious wear of the rope hanger. And the balance weight of the existing pumping unit is affected by gravity during use, which causes its motor and deceleration mechanism to be stressed and worn more seriously during use, which greatly increases the production cost of the enterprise. The invention releases a pumping unit for...
