The invention relates to a transmission shaft supporting and aligning device, and belongs to the field of rolling mill auxiliary equipment. The transmission shaft supporting and aligning device comprises a release arm rotatably mounted on a supporting base, wherein one end of the release arm is connected to and drives a swing hydraulic cylinder II, and a roller is arranged at the other end of therelease arm, embedded in a drive plate of the transmission shaft and capable of rolling along a track groove in the drive plate; the release arm is provided with a counter shaft arm which is providedwith a telescopic hydraulic cylinder and a slide slot; a telescopic rod of the telescopic hydraulic cylinder is embedded in the slide slot and slides and stretches out and draws back along the slide slot; the end of the telescopic rod is also provided with a roller which can be correspondingly matched with the other track groove in the drive plate of the transmission shaft. According to the scheme, by arranging the release arm and the counter shaft arm, the transmission shaft can be actively and accurately reset, the roller replacing time of a steel tube rolling mill is shortened, and the running reliability of equipment is improved; and meanwhile, when the transmission shaft of the steel tube rolling mill needs to be replaced, the telescopic hydraulic cylinder on the shaft arm can controlthe telescopic rod to retract, so that hoisting of the transmission shaft is not affected, and maintenance is convenient.
Description
technical field [0001] The invention belongs to the field of rolling mill auxiliary equipment, and in particular relates to a transmission shaft support and shaft alignment device. Background technique [0002] The reducer of the steel pipe rolling mill is connected with the roller through a retractable drum-shaped gear-joint shaft. The shaft body of the drum-shaped gear-joint shaft is hollow inside, and a set of spring components is arranged inside the hollow. When changing rolls, the transmission shaft drives the transmission shaft to retract through the disengagement device to break away from the connection with the rolls, and at the same time give way to the roll change channel of the frame. At this time, the transmission shaft is supported by the shaft support device, and the spring inside the transmission shaft is in a compressed state. When the new working frame is pushed in, the transmission shaft will automatically rebound under the action of its internal (compress...
