References herein to "first", "second", etc., are for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicit indication of the number of technical features indicated.
Referring to fig. 1-5, the invention provides an annealing furnace roll changing polishing system, which comprises a roll changing device 1, a roll storage rack 2 and a furnace roll deburring grinding machine 3, wherein the roll changing device 1 comprises a frame, two slide rails 12 arranged on the frame in parallel, a slide seat 13 arranged between the two slide rails 12, a slide seat driving mechanism 4 for driving the slide seat 13 to move along the length direction of the slide rails 12, a swing arm 14 rotationally connected with the slide seat 13, a swing arm driving mechanism 5 arranged on the slide seat 13 and used for driving the swing arm 14 to swing, a clamp 6 arranged on the swing arm 14 and a cooling mechanism 7 for cooling a furnace roll; the clamp 6 is used for clamping the furnace roller; the furnace roller nodule removing grinding machine 3 is used for removing nodules on the furnace roller; the roller storage frame 2 is used for storing a plurality of furnace rollers.
In practical application, as shown in fig. 3, when the furnace roller 90 works in the annealing furnace 91, the furnace roller is in a high-temperature state, and a water cooling system is required to cool and dissipate heat, so as to prolong the service life of the furnace roller; therefore, one end of each furnace roller 91 is provided with a rotary joint 92 in advance, each rotary joint 92 is provided with a water inlet joint 93 and a water outlet joint 94, the water inlet joint 93 and the water outlet joint 94 are respectively provided with a switch 95, a water flow channel is arranged inside the furnace roller, the water inlet joint 93 on the rotary joint is connected with a water inlet pipe 96 of a water cooling system, the water outlet joint 94 of the rotary joint is connected with a water outlet pipe 97 of the water cooling system, cooling water flows through the water flow channel of the furnace roller, and heat exchange is carried out on the furnace roller to realize heat dissipation and temperature reduction.
When the furnace roller works in the annealing furnace for a period of time, the furnace roller surface nodules become old furnace rollers, and the roller needs to be replaced in time, at the moment, the switches 95 on the water inlet connector 93 and the water outlet connector 94 are closed to block the cooling water in the water flow channel of the furnace roller, then the water inlet switch and the water outlet switch of the water cooling system are disconnected, and then the water inlet pipe 96 and the water outlet pipe 97 of the water cooling system are disconnected with the rotary connector 92. Then, the operator controls the slide seat driving mechanism 4 to act, and drives the slide seat 13 to move towards the furnace roller direction; the swing arm 14 is moved to the lower part of the furnace roller 90, then the swing arm driving mechanism 5 drives the swing arm 14 to gradually swing upwards until the swing arm 14 tends to be horizontal, the furnace roller 90 is clamped by matching with the clamp 6, and at the moment, because the furnace roller is still in a high-temperature state, the furnace roller 90 needs to be continuously cooled through the cooling mechanism 7; the carriage drive mechanism 4 then drives the carriage 13 to move away from the annealing furnace 91, so that the furnace rolls are extracted from the annealing furnace. When the furnace roller 90 is cooled to a preset temperature range (the cooling time is 15 minutes to half an hour), the worker loosens the clamp 6, disconnects the cooling mechanism 7 from the old furnace roller, and lifts and transports the old furnace roller to the roller storage frame 2 beside the roller changing device 1; finally, a new furnace roller on the roller storage frame 2 is hoisted to the clamp 6, the clamp 6 clamps the new furnace roller, then the slide seat driving mechanism 4 drives the slide seat 13 to move towards the direction close to the annealing furnace, and meanwhile, the swing arm driving mechanism 5 drives the swing arm 14 to swing so as to adjust the angle of the new furnace roller entering the annealing furnace and ensure that the new furnace roller smoothly enters the annealing furnace to realize installation; after the new furnace roller is installed, the clamping is loosened, the slide seat driving mechanism 4 drives the slide seat 13 to move towards the direction far away from the annealing furnace, and a water inlet pipe and a water outlet pipe of the water cooling system are respectively connected with a rotary joint on the new furnace roller, so that the new furnace roller can dissipate heat and cool when in work.
After finishing roll changing work, the staff can hoist the old furnace roller on the roller storage frame 2 to the furnace roller deburring grinding machine 3 located beside the roll changing device 1, and the excircle of the furnace roller is polished and renovated by the furnace roller deburring grinding machine 3 so as to remove the sponge iron nodules attached to the surface of the furnace roller. And the old furnace roller after being polished and debugged is changed into a new furnace roller and is hoisted and transported back to the roller storage frame 2 for caching to wait for roller replacement. Therefore, the annealing furnace roller-changing polishing system provided by the invention not only can assist workers in completing roller-changing work, but also can polish and renovate the replaced old furnace roller on site, and not only can the time and labor cost consumed by lifting the old furnace roller and the new furnace roller for a long distance be reduced, but also the transportation cost of transporting the new and old furnace roller between polishing and renovating factories can be reduced.

It can be understood that when the swing arm 14 on the sliding base 13 moves to the lower part of the old furnace roller, the first water pipe 71 can be connected with the water inlet joint 93 on the old furnace roller, then the second water pipe 72 is connected with the water outlet joint 94 on the old furnace roller, the water cooler conveys the cooling water to the water flow channel of the old furnace roller through the first water pipe 71, so that the old furnace roller dissipates heat and cools, and then the cooling water flows back to the water cooler through the second water pipe 72; naturally, the old furnace roller can be cooled after the clamp 6 clamps the old furnace roller according to actual conditions. Because the drag chain 74 can constrain the first water pipe 71 and the second water pipe 72, on one hand, the first water pipe 71 and the second water pipe 72 are arranged neatly and cannot be intertwined with each other, and part of the first water pipe 71 and the second water pipe 72 can smoothly change the bending position along with the movement of the sliding seat 13; on the other hand, the free ends of the first water pipe 71 and the second water pipe 72 can move along with the sliding base 13, so that the old furnace roller is in a cooling state in the working process of drawing the old furnace roller out of the annealing furnace 91, the old furnace roller is prevented from rapidly heating up after being cooled by a water cooling system, and the cooling time of the old furnace roller is shortened better.
