Non-beam pumping unit driven by a biaxial motor

Abstract

The non-beam pumping unit driven by a biaxial comprises a base, a tower body and a drive mechanism. The drive mechanism is mounted on the platform, comprising a biaxial motor, a large roller, a small roller, a belt and a counterweight device. The two ends of the biaxial motor are respectively connected with the two ends of the large roller through the chain and the sprocket respectively. The utility uses the biaxial motor instead of the uniaxial motor which in the prior art, the motor and the large roller on both sides are in balance, and solves the problem of partial grinding effectively and prolongs the service life of the bearing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) The utility model is further described as follows with reference to the drawings: According to the embodiment, the non-beam pumping unit driven by a biaxial motor comprises: a base 7, a tower body 1 and a drive mechanism, wherein the base 7 is fixedly mounted on the ground; the lower end of the tower body 1 is hinged on the base 7, and when take the workover the support of the pull rod can be removed and turn the tower body to a horizontal position to create more space for the workover operation.

(7) The pull rod 6 is connected between the tower body 1 and the base 7 and both ends of the pull rod 6 are respectively hinged on the tower body 1 and the base 7, and the hinge point between the tower body 1 and the base 7 and two end points of the pull rod 6 constitute a triangular supporting structure and the upper end of the tower body 1 is provided with a platform 5; the drive mechanism is mounted on the platform 5, comprising a motor reduction unit, a large roller 10, a small roller 9, a belt 4 and a counterweight device

(8) Using the biaxial motor 12 instead of the uniaxial motor which in the prior art, the biaxial motor 12 and the large roller 10 on both sides are in balance, and solves the problem of partial grinding effectively and prolongs the service life of the bearing.

(9) The pull rod 6 is connected to the tower body 1 by means of a hinge support 14, and the hinged support 14 on the tower body 1 has three, the three hinged supports 14 are arranged at equal intervals along the length of the tower body 1. When the pumping unit is in normal operation, the pull rod 6 is connected to the hinged supports 14 located at the middle and needs to be tilted at a small angle to the tower body 1. The pull rod 6 can be connected to the hinge supports 14 located on the uppermost side of the tower body 1. The bolts 13 are provided at a joint between the bottom of the tower body 1 and one end of the base 7, the bolts 13 connect the bottom of the tower body 1 to the base 7. When the tower body 1 is erected, if only supported by the pull rod 6, the pumping unit can operate normally, but the vibration and noise during operation are relatively large. The installation of the bolt 13 can be applied to the tower body 1 to further lock, and thus reducing noise and vibration.

(10) The pull rod 6 is provided with a length adjusting screw 8. The tower body 1 is provided with an angle incidence indicator 2.The inclination angle of the tower body 1 is adjusted by the length adjustment screw 8, and the inclination angle of the inclination angle indicator 2 is used to indicate the inclination angle of the tower body 1. When the length adjustment screw 8 is rotated, the inclination angle is viewed and the adjustment speed can be effectively increased.
