Description
Technical Field
The invention relates to the technical field of hot-rolling run-out tables, in particular to a hot-rolling run-out table device capable of being replaced quickly.
Background
The hot rolling run-out table is arranged in the outlet area of the hot rolling strip steel finishing mill and is usually matched with laminar flow cooling equipment for use, the main function is to convey finished strip steel which is rolled to a coiling machine, the main function is to serve as important conveying equipment of a production line, the stable operation of the run-out table directly influences the quality of the product, and once the product fails, the production rhythm is influenced and even the whole line production is stopped. According to statistics of steel plants, the shutdown rate caused by the run-out table accounts for more than 25% of the full line shutdown rate.
The traditional run-out table bearing seat is characterized in that the roller is assembled and independently fixed on the table frame by bolts, the speed of strip steel can reach more than 15m/s, the head of the strip steel can generate huge impact force on the table during the transmission process of the strip steel, at the moment, the bolts between the single table bearing seat and the independent cross beam and the bolts between the independent cross beam and the lower table frame are stressed greatly, and the bolts are loosened or broken due to frequent impact. The roller way motor and the roller way assembly shake along with the single beam, scratch is caused on the lower surface of the strip steel, the coaxiality deviation of the roller way coupler is increased, abrasion of a plum blossom pad of the roller way coupler is accelerated, and the coupler is meshed and separated even bolts of a motor base are sheared.
In addition, under the high temperature condition, the roller of the run-out table rubs with the surface of the strip steel at a high speed, the material on the surface of the roller wears faster, and the worn roller scratches the surface of the strip steel, so that the rejection rate is increased. In general, a layer of wear-resistant hard alloy material is deposited on the surface of the roller, and the deposited welding process is carried out again after the surface of the roller is worn to ensure good surface quality of strip steel, so that the roller of the output roller way needs to be disassembled and repaired regularly.
The structure schematic diagram of the traditional run-out table is shown in figures 1-2. Mainly comprises a motor 1', a bearing seat 2', a roller 3', a supporting cross beam 4', a bolt 5', a roller way frame 6', and the like. The motor 1' and the bearing seat 2' are arranged on the cross beam 4 '; an adjusting gasket group is arranged between the motor 1 'and the cross beam 4'; the motor 1' drives the roller 3' supported by the two bearing seats 2' to rotate through a coupling; the motor 1' and the bearing seat 2' are both assembled on the beam 4' by bolts; a positioning spigot is arranged between the cross beam 4 'and the roller way frame 6'; the cross beam 4' is clamped on the roller frame 6' by bolts 5 '. When the roller way is replaced every time, the bolts 5' are required to be opened, the motor 1', the bearing seat 2', the rollers 3' and the cross beam 4' are integrally hung to a maintenance area to detach and repair the rollers, after repair, the roller assembly formed by the motor 1', the bearing seat 2', the rollers 3' and the cross beam 4' is integrally hung back to the roller way frame 6', the clamping grooves between the cross beam 4' and the roller way frame 6' are accurately aligned, and then the cross beam 4' is combined with the roller way frame 6' by using the bolts 5 '. The motor base bolts, the roller bearing seats and the beam bolts, the beams and the roller frame bolts, the motor base gasket height adjustment, the positioning of the beams and the roller frame clamping grooves and the like are required to be removed or installed in the process of replacing the output roller bed, so that the operation is very complicated, the operation is inconvenient, and the efficiency is very low. As the number of the output roller ways is large, the abrasion is rapid, the disassembly and repair frequency is high, a great amount of time is required for replacing the output roller ways, the production rhythm is influenced, and the time and economic loss are large.
