Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] In the drawings, the machine base 1 is fixed on the crossbeam 14 of the tundish trolley with bolts, the base of the boom swing cylinder 2 is fixed on the boom 3 with bolts, and the stepped shaft of the machine base 1 is fixed in the shaft hole of the boom 3 At the same time, it cooperates with the output hole of the boom swing cylinder 2 and connects with a key to transmit torque to realize the rotation of the boom 3 relative to the base 1. The nut and the pressure plate at the shaft end can ensure the axial positioning of the boom 3. The stepped shaft of the boom 3 cooperates with the sliding bearing of the forearm 6, and at the same time cooperates with the output hole of the forearm swing cylinder 4 and is connected with a key to transmit torque to realize the movement of the forearm 6 relative to the forearm 3. The shaft end is connected wit...

Abstract

The invention provides a quick change device for a stopper rod for a tundish of a continuous casting machine, which belongs to the technical field of continuous casting machines. The quick change device for the stopper rod consists of a frame, a swing mechanism, a lifting mechanism, clamp forceps and a stopper rod clamping mechanism. The swing mechanism consists of a large-arm swing cylinder, a large arm, a small-arm swing cylinder and a small arm; the lifting mechanism consists of a movable rack, a transverse guide wheel, a longitudinal guide wheel and a lifting cylinder; and the stopper rod clamping mechanism consists of the stopper rod, a connecting head and a stopper rod seat. The stopper rod seat is provided with a locking arm, and the connecting head and the stopper rod seat are locked through the locking arm. When the locking is opened, the clamp forceps grip the connecting head for fixing the stopper rod, and quickly lift up and down or horizontally move to finish the change of the new and old stopper rods. The quick change device for the stopper rod has the advantages of simple motion, convenient operation, accurate stopper rod positioning and short change time, and can realize continuous casting and unstopped stopper rod change, improve the yield of the continuous casting machine and reduce the production cost.

Description

Technical field: [0001] The invention belongs to the technical field of continuous casting machinery, and in particular relates to a stopper quick-changing device for a tundish of a continuous casting machine. Background technique: [0002] The stopper rod is the control element that controls the flow of molten steel from the tundish into the mold. The closing and opening degree of the spherical end of the stopper and the nozzle at the bottom of the tundish can control the on-off and speed of molten steel injection into the crystallizer. When the stopper rod moves up, the molten steel flow area increases and the flow rate increases; on the contrary, when the stopper rod moves down, the flow area decreases until it is completely closed. The lining, nozzle and stopper of the tundish are all made of refractory materials. Due to different operating conditions, there is a big gap in their service life. The service life of the lining and nozzle of the tundish is longer, while the...
