The top end of the tensioning screw rod is provided with a groove, a ball is embedded in the groove, and the tensioning screw rod is abutted to the thimble hole of the belt roller shaft through the ball.
The centers of the two screw holes are positioned on the diameter line of the horizontal direction of the roller shaft. Moment balance when can ensure drum shaft base atress on the one hand, on the other hand can avoid adjusting screw and drum shaft base to produce the interference, has solved the tradition simultaneously because centering is inaccurate, draws the automatic problem that drops of horse.
The arc-shaped groove on the extension plate of the fixed seat is matched with the outer diameter of the roller shaft and can clamp the roller shaft, the sleeve body of the fixed seat is matched with the base of the roller shaft in shape and size, the pull plate is provided with a threaded hole, and the tensioning screw rod and the pull plate form screw rod transmission; during operation, the external power of tensioning lead screw is as the driving body, and the arm-tie will be along with tensioning lead screw's turned angle according to the helical pitch conversion of corresponding specification rectilinear motion, and the arm-tie drives the corresponding rectilinear motion of fixing base realization through adjusting screw, and then dismantles the drum axle base from the belt drum axle. A ball which is fully stained with lithium base grease is placed between the tensioning screw rod and the thimble hole of the roller shaft, so that the tensioning screw rod is changed from friction stress application to rolling stress application, the labor intensity is reduced by more than half, the roller shaft base can be easily dismounted perfectly, and the device can also be suitable for dismounting the shaft bearing block.
The utility model discloses flexible operation, convenient to use have solved that the drum shaft base dismantles the degree of difficulty big, technical problem that intensity of labour is big. The phenomenon that the base of the roller shaft is easy to damage in the maintenance process is avoided; the shaft can be used anywhere on the well, and the technical problem that the maintenance of the belt roller shaft is limited by space is solved.
