Detailed Description
The present invention will be described in detail below with reference to the following examples and accompanying drawings.
Example 1
See fig. 1. The preposed direct-balanced beam-pumping unit comprises a suspension rope 6, wherein the lower end of the suspension rope 6 is connected with a rope hanger 7, and the upper end of the suspension rope 6 is connected with a horse head 10; the balance weight device further comprises a balance weight support 4, a balance weight 3, a roller 1, a connecting belt 2, a base 5 and a top plate 20. The counterweight support 4 stands in front of the horse head 10, the lower end of the counterweight support 4 is fixed on the base 5, and the top plate 20 is arranged at the upper end of the counterweight support 4. The drum 1 is horizontally mounted on a top plate 20. The connecting belt 2 winds the roller 1, one end of the connecting belt 2 is connected with the rope hanger 7, and the other end of the connecting belt 2 is connected with the balance weight 3. The balance weight 3 is arranged in a space surrounded by the balance weight bracket 4 and can move up and down along with the connecting belt 2.
Example 2
See fig. 1. Leading direct balance beam-pumping unit, on the technical scheme basis that embodiment 1 recorded, the gyro wheel is established in the 3 outsides of counter weight, and counter weight support 4 inner wall is equipped with the vertical spout with gyro wheel complex, ensures that counter weight 3 does not sway at the removal in-process, full play good balanced function.
Example 3
See fig. 1. A front direct balance beam pumping unit is characterized in that on the basis of the technical scheme recorded in embodiment 1, circumferential limiting convex rings are arranged on the surfaces of rollers 1 on two sides of the normal winding position of a connecting belt 2, and the connecting belt 2 is ensured not to deviate from a normal running track.
Example 4
See fig. 1. On the basis of the technical scheme recorded in embodiment 1, rolling bearings with reliable performance, high bearing capacity and convenient maintenance are installed at two ends of a rotating shaft of a roller 1 so as to keep the normal working position and the rotating precision of the rotating shaft.
Example 5
See fig. 1. On the basis of the technical scheme recorded in embodiment 1, the bottom of a counterweight support 4 is provided with a first reinforcing rib 21 connected with a base 5, so that the counterweight support 4 can be better fixed; the top of the weight bracket 4 is provided with a second reinforcing rib 22 connected with the top plate 20, which helps the top plate 20 to be better fixed.
Example 6
See fig. 1. The front direct balance beam-pumping unit is characterized in that on the basis of the technical scheme recorded in embodiment 1, a counterweight support 4 is fixed on a base 5 through a high-strength bolt; the high-strength bolt is made of No. 45 steel with high strength and excellent deformation resistance. The adoption of high strength bolt can guarantee the fastness of being connected of counter weight support 4 and base 5.
The basic working principle of the invention is as follows:
when the pumping unit ascends, the horse head 10 is driven to ascend through the reduction gearbox 16, the connecting rod 14 and the walking beam 11, the polished rod 8 is lifted to move upwards, and meanwhile, the balance weight 3 is reversed through the roller 1 to lift the polished rod 8 together to ascend; when the pumping unit moves downwards, the balance weight 3 is driven to move upwards by the dead weight of the polished rod 8.
The invention cancels the crank counterweight, adopts front direct balance, and the balance rate can reach 95-105%. Because the balance rate is manually adjusted, but the balance weight on the original crank is more than 1 ton, the adjustment is complicated and difficult and the potential safety hazard is larger, the oil field requires that the balance rate reaches 70% -130% to be qualified, the balance weight needs to be adjusted backwards when the balance weight is less than 100% to be underbalanced, the balance weight needs to be adjusted backwards when the balance weight is more than 100% to be overbalanced, the balance weight needs to be adjusted backwards and forwards, namely, the balance rate is mainly realized by adjusting the length of the force arm, and the operation is difficult to adjust and then the balance weight is not adjusted when the balance weight meets the requirement through the inspection of the ratio of the downlink current to the uplink current on site. However, the invention changes into counterweight balance, and each piece of 10kg of counterweight iron in the counterweight box can be conveniently increased and decreased, so that accurate balance can be achieved, namely the balance weight reaches 95% -105%.
