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 installed in the exit region of the hot rolling strip steel finishing mill, is usually used together with laminar flow cooling equipment, has the main function of conveying finished rolled finished strip steel to a coiler, and is used as important conveying equipment of a production line, the stable operation of the run-out table directly influences the product quality, and once a fault occurs, the production rhythm is influenced and even the whole line production stop is caused. According to the statistics of steel mills, the shutdown rate caused by the reasons of the run-out roller table accounts for more than 25 percent of the full-line shutdown rate.
The traditional output roller bed bearing seat usually adopts bolts to assemble and independently fix rollers on a roller bed frame, and because the speed of strip steel can reach more than 15m/s, the head of the strip steel can generate huge impact force on a roller bed in the transmission process of the strip steel, at the moment, the bolts between the single roller bed bearing seat and the single cross beam of the single roller bed bearing seat and the bolts between the single cross beam and the lower roller bed frame are subjected to huge stress, and frequent impact can cause the loosening or the fracture of the bolts. The roller way motor and the roller way assembly shake along with the single cross beam, scratches the lower surface of the strip steel, increases the coaxiality deviation of the roller way coupler, accelerates the abrasion of the plum blossom pads, and causes the coupler to be disengaged by tooth beating or even the motor base bolt to be cut off.
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 surface material of the roller is abraded quickly, and the abraded roller can scratch the surface of the strip steel, so that the rejection rate is increased. Usually, a layer of wear-resistant hard alloy material is overlaid on the surface of the roller, and overlaying processing should be carried out again after the surface of the roller is worn so as to ensure good surface quality of the strip steel, so that the roller of the run-out table needs to be periodically disassembled and repaired.
The structure schematic diagram of the traditional run-out table is shown in attached figures 1-2. The roller bed mainly comprises a motor 1 ', a bearing seat 2', a roller 3 ', a supporting beam 4', a bolt 5 ', a roller bed frame 6' and the like. The motor 1 ' and the bearing seat 2 ' are both arranged on the 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 fastened on the cross beam 4 ' by bolts; a positioning spigot is arranged between the cross beam 4 'and the roller bed frame 6'; the cross beam 4 ' is combined on the roller frame 6 ' by a bolt 5 '. When the roller way is replaced every time, the bolt 5 ' needs to be opened, the motor 1 ', the bearing seat 2 ', the roller 3 ' and the cross beam 4 ' are integrally hung to a maintenance area to disassemble and repair the roller, after repair, the roller assembly consisting of the motor 1 ', the bearing seat 2 ', the roller 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 ' and the roller way frame 6 ' are closed by the bolt 5 '. Need demolish or install motor base bolt, roll table bearing frame and crossbeam bolt, crossbeam and roll table frame bolt at the change rollgang in-process, adjust motor base gasket height, carry out crossbeam and roll table frame draw-in groove location etc. very loaded down with trivial details, and the operation is inconvenient, and efficiency is very low. Because the output roller ways are large in quantity and fast in abrasion, the disassembly and repair frequency is high, a large amount of time is needed for replacing the output roller ways, the production rhythm is influenced, and the time and economic losses are large.
