Problems solved by technology

[0002] The workover rig is the main equipment for oilfield workover operations. Most of the current diesel workover rigs and electric workover rigs transmit power to the drum through angle transmission and reduction box, and then realize the workover operation through the swimming system. The system is relatively complicated, which makes the noise during the workover work very loud, the transmission efficiency is low and the failure rate is high, and the corresponding maintenance cost is very high

Abstract

The invention discloses an electric direct drive workover rig. A well site transformer is arranged at a well repair working site, and the workover rig comprises an automobile chassis, an engine, a generator, a frequency converter, a direct drive motor and a roller; the engine, the generator, the frequency converter and the direct drive motor are all fixed to the automobile chassis; the generator is in transmission connection with a gearbox connected with a power takeoff through a gear, and the power takeoff is connected with a rotating shaft of the generator through a transmission shaft; the generator or the well site transformer is connected with the frequency converter and the direct drive motor through an electric control box electrically, and the frequency converter is connected with the direct drive motor electrically; and the roller is in transmission connection with the direct drive motor electrically. The electric direct drive workover rig is not only convenient in operation and high in automation degree, but also reliable in performance, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of workover rigs, in particular to an electric direct drive workover rig. Background technique [0002] The workover rig is the main equipment for oilfield workover operations. Most of the current diesel workover rigs and electric workover rigs transmit power to the drum through angle transmission and reduction box, and then realize the workover operation through the swimming system. The system is relatively complicated, which makes the noise in the workover process very large, the transmission efficiency is low and the failure rate is high, and the corresponding maintenance cost is very high. [0003] Therefore, how to provide an electric direct-drive workover rig has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the present invention provides an electric direct-drive workover rig, which is not only easy to operate, has a high degre...
