The working principle of the invention is as follows:
the rope head of the old steel wire rope needing to be replaced by the metallurgical crane passes through the opposite pinch wheel surfaces of the driving wheel 43 and the opposite pinch wheel 44, then goes upwards to bypass the guide wheel 16, and is wound and fixed on the winding drum 21; starting the metallurgical crane reversely to enable the old steel wire rope to descend from the metallurgical crane;
the metallurgical crane is a large-tonnage crane, the diameter of the used steel wire rope is several centimeters thick, so the steel wire rope is heavy, the steel wire rope can drive the driving wheel 43 to rotate by means of dead weight in the descending process, the driving wheel 43 drives the reversing gear 41 to rotate, the reversing gear 41 drives the driving wheel 31 to rotate, the driving wheel 31 is in fit connection with the reel driving wheel 23 through surface friction, so the reel driving wheel 23 rotates along with the rotation of the driving wheel 31, and finally the reel 21 rotates to wind the steel wire rope through the reel driving wheel 23.
Usually, the winding drum 21 is in a circular truncated cone shape, and in the process of winding the steel wire rope on the winding drum 21, the winding radius of the steel wire rope changes with the winding thickness and the winding position on the circular truncated cone-shaped winding drum 21, for example, the winding radius of the steel wire rope increases due to the increase of the winding thickness, and the winding radius of the steel wire rope decreases due to the movement of the winding position of the steel wire rope from the lower end to the upper end of the circular truncated cone-shaped winding drum 21, so if the linear speed of the steel wire rope descending is to be constant, the angular speed of the rotation;
in the process of winding the steel wire rope by the winding device, when the winding radius of the steel wire rope is increased, if the original winding drum 21 is continuously kept to rotate at a certain angle, the winding linear speed of the steel wire rope is increased, the steel wire rope is further tightened, the steel wire rope positioned between the guide wheel 16 and the driving wheel 43 is tightened, so that the steel wire rope has an upward force on the driving wheel 43, after the driving wheel 43 is acted by the upward force, the driving seat 34 is integrally pulled up through the vertical rod 46, the driving wheel 31 is driven to move upwards by the driving seat 34, the radius of the contact point of the outer side surface of the winding drum driving wheel 23 and the driving wheel 31 is increased, namely, the transmission ratio between the winding drum driving wheel 23 and the driving wheel 31 is reduced, the angular speed; on the contrary, when the winding radius of the steel wire rope is reduced, the steel wire rope is loosened, the transmission seat 34 is lowered under the action of gravity, the transmission ratio between the reel driving wheel 23 and the transmission wheel 31 is increased, the angular speed of the reel driving wheel 23 is increased, and finally the angular speed of the reel 21 is increased; through the regulation of the angular speed of the winding drum 21, the winding linear speed of the steel wire rope is constant during winding, and the running stability of the device is ensured.
According to the invention, the counterweight 15 is arranged to balance part of gravity of the transmission seat 34, so that the transmission seat 34 can be pulled to move upwards as long as the steel wire rope has a slight upward acting force on the driving wheel 43, and the response speed and the sensitivity are improved;
