  • Patent number: 10378531
    Abstract: The utility belongs to the field of the non-beam pumping unit, specifically relating to a non-beam pumping unit driven by a motor reduction unit. The non-beam pumping unit driven by a motor reduction unit comprises a base, a tower body and a drive mechanism. The drive mechanism is mounted on the platform, comprising a motor reduction unit, a large roller, a small roller, a belt and a counterweight device. The motor reduction unit drives the large roller to rotate by a coupling, and one end of the belt is connected with a beam hanger and the other end hangs down after wrapping around the large roller and the small roller from the upper side and then connected with the counterweight device. The motor reduction unit is composed of a motor and a planetary gear reducer in series.

  • Patent number: 10233985
    Abstract: The utility model provides a hand brake system used on a non-beam pumping unit, including a drive mechanism mounted at the lower part of the pumping unit and an actuator mounted on a side of the main drive sprocket of the pumping unit, and the drive mechanism and the actuator are connected by a wire rope. In the utility model, the drive mechanism and actuator of the brake system are separately arranged, thus ensuring promptness of braking and eliminating the potential safety hazard of workers falling from a height. The braking mode of the existing brake system on a pumping unit is to achieve the braking function by locking the rotary shaft from the outer side. The braking force upon braking is relatively small and the braking reliability is relatively poor.

  • Patent number: 10184467
    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.

  • Publication number: 20180291988
    Abstract: The utility belongs to the field of the non-beam pumping unit, specifically relating to a single motor non-beam pumping unit with a reducer built in the roller. The single motor non-beam pumping unit with a reducer built in the roller comprises a base, a tower body and a drive mechanism. The upper end of the tower body is provided with a platform and the drive mechanism is mounted on the platform. The drive mechanism comprises a motor, a reduction mechanism, a roller and a belt. According to the utility, the reduction mechanism is built in the roller, so that the damage to the reduction mechanism caused by the natural environment such as wind, rain and sun can be avoided, thus extending the service life and maintenance cycle of the reduction mechanism and improving the stability of operation of the device.
