An apparatus for tripping oil pipe and a system for automatic well workover comprises an elevator transfer device for transferring an elevator connected with an oil pipe, the elevator transfer device being structured for enabling continuous, automatic tripping operations of the oil pipe. The elevator transfer device comprises a lifting assembly used for lifting and releasing an oil pipe engaged with the elevator, and an elevator transport assembly used for transferring an elevator at a wellhead and/or an elevator on the lifting assembly. The apparatus for tripping oil pipe can lower the labor intensity and improve operation safety.

Apparatus for tripping oil pipe and system for automatic well workover

A crank-type non-beam pumping unit, including a belt, a foundation, a crown sheave, a frame, a support rod, a belt pulley, a pin shaft, a crank, a transmission shaft, and a bracket. The bottom of the frame is disposed on the foundation, and the top of the frame is supported by the support rod. The top of the support rod is hinge connected to the frame, and the bottom of the support rod is hinge connected to the foundation. The bracket is disposed on the foundation, the transmission shaft is disposed on the bracket, and the crank is disposed on the transmission shaft. The crank rotates synchronously with the transmission shaft, and the belt pulley is disposed on one end of the crank via the pin shaft. One end of the belt bypasses the crown sheave, and is connected to a smooth sucker rod.
