Description
技术领域technical field
本发明涉及一种油缸自动卸荷的技术领域,更具体地说,它涉及一种连铸机钢包滑板机构油缸自动卸荷装置及工作方法。The invention relates to the technical field of automatic unloading of oil cylinders, more particularly, it relates to an automatic unloading device and working method of an oil cylinder of a ladle sliding plate mechanism of a continuous casting machine.
背景技术Background technique
连铸机在连续浇钢过程中,一个钢包浇完钢水后需用钢包回转台将空钢包转入吊离区待行车吊走,此时安装在钢包的滑板机构上的液压油缸需拆卸,留待下一个新的装满钢水的钢包吊上钢包回转台再将液压油缸安装在滑板机构上循环使用。钢包滑板机构是固定安装在钢包水口侧面,机构内有一油缸安装底座用于安装液压油缸,钢包滑板机构的液压油缸可以安装在滑板机构的油缸安装底座里并可拆卸。钢包滑板机构通过液压油缸活塞杆伸缩来控制滑板机构的开闭,用以控制钢包钢水的流出的流量大小。传统的液压油缸安装方式为人工将液压油缸与油缸安装底座、油缸活塞杆与滑板T型连杆一起精准套合,再用手动插销对油缸实现固定。通常钢包内钢水温度为1500℃左右,滑板机构表面温度在100℃以上。在人工安装与拆卸过程中工人需要忍受长时间的高温烘烤,并存在烫伤的安全隐患,于是采用机器人替代人工操作。使用机器人自动安装、拆除滑板机构油缸就需要人工自动控制油缸压力卸荷,使油缸卡爪与机构连接的摩擦力降到极低,原系统在18MPa情况下,摩擦力极大,超过机器人的受力,机器人不能将油缸自动拆下来。In the continuous casting process of the continuous casting machine, after a ladle has been poured with molten steel, the empty ladle needs to be transferred to the lifting area by the ladle turntable to be lifted away by driving. At this time, the hydraulic cylinder installed on the sliding plate mechanism of the ladle needs to be removed and left to The next new ladle filled with molten steel is hung on the ladle turntable, and then the hydraulic cylinder is installed on the sliding plate mechanism for recycling. The ladle sliding plate mechanism is fixedly installed on the side of the ladle nozzle. There is an oil cylinder mounting base in the mechanism for installing the hydraulic cylinder. The hydraulic cylinder of the ladle sliding plate mechanism can be installed in the cylinder mounting base of the sliding plate mechanism and can be removed. The ladle sliding plate mechanism controls the opening and closing of the sliding plate mechanism through the expansion and contraction of the piston rod of the hydraulic cylinder to control the flow rate of the molten steel from the ladle. The traditional hydraulic cylinder installation method is to manually fit the hydraulic cylinder with the cylinder mounting base, the cylinder piston rod and the sliding plate T-shaped connecting rod, and then use the manual latch to fix the cylinder. Usually, the temperature of molten steel in the ladle is about 1500℃, and the surface temperature of the sliding plate mechanism is above 100℃. In the process of manual installation and disassembly, workers need to endure long-term high-temperature baking, and there is a safety hazard of scalding, so robots are used instead of manual operations. Using the robot to automatically install and remove the slide mechanism cylinder requires manual and automatic control of the cylinder pressure unloading, so that the friction between the cylinder jaws and the mechanism is reduced to a very low level. The original system has a great friction under the condition of 18MPa, which exceeds the load of the robot. force, the robot cannot automatically remove the cylinder.
