[0021] This pre-tightening machine for installing oil casing and couplings, through the cooperation of a slide rail with a first and second slider, allows for flexible adjustment of the positions of the retainer and fixing bracket, facilitating the connection between the oil casing and coupling. The rotating sleeve inside the retainer, driven by a first electric telescopic rod, drives a first clamp to securely clamp the coupling and rotates it via a rotating mechanism for pre-tightening. The fixing bracket, equipped with a second electric telescopic rod and a second clamp, secures the oil casing. A third electric telescopic rod and a support plate on the bracket provide auxiliary support for the oil casing, ensuring stability during installation. The oil casing dust removal mechanism cleans dust and impurities from the surface of the oil casing before installation, ensuring connection quality. Through the setup of a cleaning pipe rack, nozzle, and blower, the airflow generated by the blower is transmitted through the cleaning pipe rack to the nozzle, which then blows the airflow onto the surface of the oil casing, quickly and effectively removing dust, debris, and other impurities. This device, with several air nozzles arranged in a ring around the casing, can simultaneously clean the oil casing from multiple angles, ensuring that dust and impurities around the casing are removed and avoiding cleaning dead zones. The drive shaft, worm gear, and worm wheel configuration allow the drive shaft to rotate, driving the worm gear on the outer side of the rotating sleeve to mesh with the worm wheel on the outer side, transmitting power to the rotating sleeve and ensuring its stable rotation. The drive shaft is electrically rotated via a motor output connected to one end. The second slider is electrically moved via a fourth electric telescopic rod fixed to one end face of the second slider, allowing the oil casing to fit snugly against the coupling. Supports at the four corners of the frame's bottom enhance the device's stability. This invention effectively achieves rapid cleaning of the oil casing, preventing dust and other impurities from wearing down the threads, and has high practical value. Attached Figure Description
