The main body assembly comprises a main body part 1, a lining part and a hinge part 6, wherein the main body part 1 is provided with a through hole 3, the lining part is arranged in the through hole 3, one side of the through hole 3 is provided with a gap, the hinge part 6 is rotatably arranged on one side of the gap, and the hinge part 6 can rotate to the gap and is covered on the gap. In the above main body assembly, the main body 1 is a main component for clamping the pipe body equipment such as the oil pipe, and the bushing portion is used for properly filling the through hole 3 by placing the pipe body equipment in the through hole 3, and simultaneously plays a role in reducing the abrasion between the bushing portion and the pipe body equipment such as the oil pipe. The hinge part 6 is used for clamping or loosening the pipe body equipment in the through hole 3, and the hinge part is rotated to enable the movable hinge rotating handle to be close to the through hole 3 to completely clamp the pipe body equipment such as an oil pipe in the through hole 3 and the like, so that the pipe body equipment can be clamped. Similarly, the movable leaf is rotated in the reverse direction to loosen the pipe body equipment. The driving assembly includes a first driving part connected to the hinge part 6 for driving the hinge part 6 to rotate, and the first driving part is connected to the control unit. The first driving part is used for driving the loose leaf to rotate, and can enable the loose leaf to have a continuous acting force, so that the loose leaf always pushes the pipe opening body equipment tightly in the clamping process. The first driving part is connected with the control unit, and the action control of the first driving part is realized through the control unit, so that the rotation of the loose leaf can be effectively controlled. The turning output end of the turning unit 11 is connected to one side of the main body 1 to drive the main body 1 to rotate, and the turning unit 11 is connected to the control unit. Above-mentioned upset subassembly 11 can realize the upset of body equipment, and at the actual hoist and mount in-process, no matter hang out the oil well with body equipment such as oil pipe, still hang into with the oil well, all need place body equipment level, consequently upset subassembly 11 can make body equipment overturn to suitable position, makes things convenient for the installation or the depositing of body equipment. Consequently, this open upset elevator of hydraulic pressure side can accomplish the hoist and mount to body equipment such as drilling rod, oil pipe, sucker rod automatically, has practiced thrift the human cost, reaches to have promoted work efficiency, can also eliminate the potential safety hazard that operating personnel manual operation brought simultaneously.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
