Technical Field
The utility model belongs to the roller field of tearing open and trade equipment, a device is demolishd to stove roller of stainless steel medium plate annealing stove is related to.
Background
The annealing furnace is a common device for heat treatment in the steel industry, and is one of indispensable devices in the production process of stainless steel medium and heavy plates. The furnace chamber of the annealing furnace is internally provided with a set of complete roller way system, the roller way system consists of a plurality of furnace rollers, the end part of each furnace roller is arranged in bearing seats at the two ends of the furnace body of the annealing furnace, and a transmission motor is connected with the furnace rollers through a universal joint to drive the furnace rollers to run. At present, the surface of a furnace roller of a stainless steel medium plate annealing furnace is cast by a refractory material, the length of the furnace roller is 3000mm, the diameter of the furnace roller is 400mm, the shaft diameter length of one end of the furnace roller is 30mm, and the shaft diameter length of the other end of the furnace roller is 40mm. After the furnace roller is used for a period of time, the refractory material on the surface of the furnace roller is worn and falls off by the plate blank, so that the diameter of the roller is reduced, and the furnace roller cannot meet the process requirements of stainless steel medium plate production, so that the furnace roller needs to be replaced. The difficult point of replacement is mainly in dismantling the furnace roller, the method of dismantling is to dismantle the shaft coupling and the expansion sleeve bearing of the drive side at first, dismantle the bearing end cover of the operation side again, then push out the furnace roller from the operation side out the annealing furnace chamber with the press, and then draw out the furnace roller from the annealing furnace chamber with the help of overhead traveling crane and manpower, adopt the above-mentioned dismantlement mode to waste time and energy, inefficiency, because the furnace roller quantity is more, change, maintenance efficiency is low, workman intensity of labour is big, annealing furnace shut-down time is longer, seriously influences output, causes certain loss for the enterprise.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a stove roller of stainless steel cut deal annealing stove demolishs device to the problem that prior art exists, this dismounting device can be convenient for carry out the dismantlement of stove roller to improve roll table maintenance efficiency, reduce workman intensity of labour.
Therefore, the utility model adopts the following technical scheme:
the furnace roller dismantling device of the stainless steel medium plate annealing furnace comprises a bottom plate, wherein the bottom plate is of a rectangular structure, a plurality of carrier roller sets are uniformly arranged on a central line of the bottom plate, each carrier roller set comprises a horizontal carrier roller and a side carrier roller, the horizontal carrier roller is fixed on the bottom plate through a horizontal carrier roller frame, and the two side carrier rollers are symmetrically arranged on two sides of the horizontal carrier roller through the side carrier roller frames; a fixed pulley is arranged on one side of the central line of the carrier roller group and fixed on the base, a lifting mechanism is arranged above the fixed pulley, a steel wire rope is arranged at the movable end of the lifting mechanism, and the other end of the steel wire rope is wound around the fixed pulley and used for being connected with the furnace roller of the annealing furnace.
Further, the lifting mechanism is a crane.
Further, the included angle between the side carrier roller and the horizontal plane is 30-60 degrees.
Further, the roller sets comprise 6 to 10 groups, and the distance between two adjacent roller sets is 500 to 300mm.
Furthermore, lifting lugs are arranged on the base, and the four lifting lugs are uniformly distributed on four corners of the base.
The utility model discloses following beneficial effect has:
(1) The overhead travelling crane and the steel wire rope are used for traction, manual operation is not needed, the labor intensity of workers is reduced, and the working efficiency is improved;
(2) Through the arrangement of the fixed pulleys and the carrier roller groups, the furnace roller moves linearly along with the carrier roller groups, so that the safety risk in the process of disassembling the furnace roller is reduced;
(3) The structure is simple and reliable, the operability is strong, and the popularization is good.
