Sucker rod elevator

Abstract

The embodiment of the invention discloses a sucker rod elevator, and belongs to the technical field of petroleum engineering equipment. The sucker rod elevator comprises a base station body, a rod clamp assembly, a gear moving ring, a distance limiting gear, a motor, a protective cover and a power control system, wherein the rod clamp assembly is located in the center of the base table body, the gear moving ring rotates around the rod clamp assembly, the motor is fixed to the side, opposite to the opening direction, of the base table body through the protective cover, the distance limiting gear is installed on a driving shaft of the motor, a gear part of the distance limiting gear is meshed with a gear part of the gear moving ring, the protective cover is connected with the base table bodyand surrounds the distance limiting gear and the motor, and the power control system is connected with the motor and used for controlling the motor to work. According to the sucker rod elevator, therod clamp assembly is driven by the motor, automatic hooking and unhooking of the sucker rod elevator are achieved, operation efficiency is improved, and safety risks are reduced.

Description

technical field [0001] The embodiment of the present application relates to the technical field of petroleum engineering equipment, in particular to a sucker rod elevator. Background technique [0002] There are a large number of lifting and lowering of sucker rods in the downhole operations of domestic petroleum systems, which generally include a series of work such as manual hanging and picking of elevators, push-pull control of threaded hydraulic tongs, and receiving and sending sucker rods. The sucker rod elevator is the key equipment in the lifting and lowering of the sucker rod. It is connected with the lifting equipment through hooks, rings, etc. to form a lifting system. [0003] The sucker rod elevator is tongue spring self-locking type, and torsion spring and front and rear tongues are installed inside it. In the process of manually hanging and removing the elevator, when the sucker rod needs to be held, the rear tongue is manually pressed, and the rear tongue is ...
