Description
Technical Field
The utility model belongs to the technical field of cold rolling mill mechanical equipment and specifically relates to a large-scale shaft coupling heating heat preservation device of rolling mill.
Background
The main transmission device, the coiling machine and the like in the steel rolling production process flow are connected with the motor through the large-scale coupler, the large-scale coupler of the rolling mill needs to be replaced when worn due to high rolling speed of cold rolling, the replacement can be completed within 3 days, and 2 persons are needed for 4 hours by adopting manual heating; because the heating temperature of the coupler has higher requirements and the surface can not be annealed, the heating temperature of the coupler needs to meet certain conditions: the heating temperature cannot exceed 210 ℃ so as to avoid influencing annealing and shorten the service time; the heating speed cannot be too high, so that the heating temperature of the coupler is not uniform; the heating temperature of the coupling is accurately controlled, and the heat preservation needs time; and errors in manual monitoring are avoided. The common heating method has uneven heating, the temperature is not easy to control, the annealing of the coupler is easy to cause, and the service time of the coupler is influenced.
Disclosure of Invention
The utility model aims at solving the existing problem above, provide and maintain simple, digital display, without personnel monitor, self-heating keeps warm, time can be established, during hoist and mount, the large-scale shaft coupling heating heat preservation device of rolling mill that heating heat preservation device is difficult for removing.
The utility model discloses large-scale shaft coupling of rolling mill heating heat preservation device, its characterized in that: the heating and heat-preserving device is provided with a base, a heating and heat-preserving cover is buckled on the base, a lifting table is arranged on the base, a rotating table for placing a coupler is arranged on the lifting table, the heating and heat-preserving cover is provided with a shell, the shell is of a vacuum jacket structure, the vacuum jacket structure forms a vacuum heat-preserving layer, a heating resistance wire and heat-preserving cotton are arranged on the inner wall of the shell from inside to outside, a heating and heat-preserving controller is arranged on the outer wall of the shell, a digital display screen is arranged on the heating and heat-preserving.
The bottom of the base is provided with rollers.
The side of four bights of base all is equipped with fixed earrings.
The top of the heating and heat-preserving cover is provided with a lifting lug.
The utility model discloses simple structure, it is convenient to maintain, digital display, without personnel's control, self-heating keeps warm, and the time can be established the advantage such as.
