Interlocking device for lifting and limiting of ladle cover of vertical heating device and using method thereof

Abstract

The invention relates to an interlocking device for lifting and limiting of a ladle cover of a vertical heating device and a using method of the interlocking device. The interlocking device mainly comprises supporting frame, a height limiter and a speed reducer middle rotary shaft and is characterized in that the lifting and limiting of the ladle cover of the vertical heating device are controlled through the height limiter, the height limiter is connected with the tail end of the speed reducer middle rotary shaft, and the height limiter is fixed to the supporting frame. An electric motor drives the speed reducer middle rotary shaft to rotate, the middle rotary shaft rotates to drive a height limiter winding drum to rotate, a winding drum shaft drives a worm and a worm gear to rotate, a cam on a worm gear shaft rotates synchronously, the flange part of the cam is in contact with a limit switch when rotating to a certain position, the limit switch acts to cut off a power source which rises or falls, so that the ladle cover of the heating device is stopped at the limiting position, limiting is adjusted by adjusting the height limiter, and thus the positioning function is achieved. According to the interlocking device for lifting and limiting of the ladle cover of the vertical heating device and the using method of the interlocking device, lifting and limiting of the ladle cover of the vertical heating device are controlled through the height limiter, the problem that limiting failures occur easily in the prior art is effectively solved, and the use effect is remarkable.

Description

technical field [0001] The invention relates to a lifting and lowering interlocking device for a vertical roaster cover, which is a lifting control tool for a vertical roaster cover, and relates to the technical field of steelmaking equipment, in particular to a vertical ladle Roaster cover lifting interlocking device. The invention also relates to a method for using the up-and-down and position-limiting interlocking device for the cover of the vertical toaster. Background technique [0002] The ladle is widely used in the steel casting industry. It is a kind of equipment used to receive molten steel and pour or bottom pour the molten steel into the mold to obtain castings. It is also used in the refining of molten steel outside the furnace. The ladle generally needs to be baked after it is newly built and before it is filled with molten steel. The device used to bake the ladle is called a ladle baker, also known as a ladle baker. [0003] The lifting limit of the ladle ve...

Problems solved by technology

[0004] In order to solve the problem of failure of the limit position of the cover of the steel-making ladle baker and to improve the reliability of the limit interlock of the cover, the invention discloses a lift limit interlock device of the cover of the vertical baker. The equipment uses a height limiter for limit chain control, which has the advantages of light weight, small size, convenient installation and debugging, sensitive and accurate response, stable and reliable, and long service life. The interlocking of the roaster is more stable and reliable, and the service life is longer, which is convenient for maintenance and repair

The height limiter is used to effectively solve the problem of frequent failure of the previous limit. The height limiter is adopted, which is reliable in action, convenient in control and remarkable in use effect.
