Device for turning on and turning off charging bell

Abstract

The invention discloses a device for turning on and turning off a charging bell, relates to a device for turning on and turning off a vertical furnace charging bell, and aims at providing the device for turning on and turning off the charging bell, which is simple in structure and is capable of prolonging the service life of a wire rope for lifting the charging bell. The device for turning on and turning off the charging bell comprises a driven wheel (3) connected with a draw bar on the charging bell through a conveyor belt, a driving wheel (2) connected with a winding engine through the conveyor belt, and a guide wheel (1) between the driven wheel (3) and the driving wheel (2), wherein the driven wheel (3) and the driving wheel (2) are small rope wheels; the guide wheel (1) is arranged at the top and is a chain wheel; a chain (4) is wound on the guide wheel (1); one end of the chain (4) is connected with a rotating center of the driven wheel (3); and the other end of the chain (4) is connected with the rotating center of the driving wheel (2).

Description

technical field [0001] The invention relates to a closing and opening device, in particular to an opening and closing device for a shaft furnace charging bell. Background technique [0002] The material bell includes a large material bell and a small material bell, which are respectively used to realize the material distribution and loading of the material bell. There are two openings at the upper and lower ends of the material bell. The opening and closing of the shaft furnace mouth and the lower mouth, the opening and closing device for the shaft furnace bell in the prior art is usually composed of the top guide wheel, the middle guide wheels on both sides, and the 15.5mm guide wheel wound on the top guide wheel and the middle guide wheel. One end of the steel wire rope is connected to the pull rod on the material bell, and the other end of the steel wire rope is connected to the winch. When using this device to lift the shaft furnace material bell, the steel wire rope wou...

[0002] The material bell includes a large material bell and a small material bell, which are respectively used to realize the material distribution and loading of the material bell. There are two openings at the upper and lower ends of the material bell. The opening and closing of the shaft furnace mouth and the lower mouth, the opening and closing device for the shaft furnace bell in the prior art is usually composed of the top guide wheel, the middle guide wheels on both sides, and the 15.5mm guide wheel wound on the top guide wheel and the middle guide wheel. One end of the steel wire rope is connected to the pull rod on the material bell, and the other end of the steel wire rope is connected to the winch. When using this device to lift the shaft furnace material bell, the steel wire rope wound at the position of the top guide wheel is usually subjected to a large force, resulting in the winding on the top. The wire rope at the guide wheel is often severely worn, and because the working stroke of the wire rope is short when it is pulled, and in the process of feeding or distributing the material, some particles will inevitably fall, and these particles fall on the guide wheel and the wire rope. On the contact surface between them, this kind of wear will intensify in the process of repeated and frequent lifting of the material bell, and even break in severe cases, causing the entire wire rope to be scrapped, which in turn leads to the failure of the opening and closing of the material bell, affecting the material bell The work of loading and distributing materials; in addition, using the steel wire rope to cooperate with the guide wheel to transmit the motion has high friction and poor lubrication effect. At the same time, the steel wire rope is prone to slipping during the transmission motion process, which is not conducive to the transmission of motion
