Quick fixing shaft replacement device for pig casting machine maintenance and fixing shaft replacement method

Abstract

The invention discloses a quick fixing shaft replacement device for pig casting machine maintenance and a fixing shaft replacement method. The quick fixing shaft replacement device comprises a base, a lifting device is fixed on the base, an adjustable replacement support is arranged on an output shaft of the lifting device, a sliding support is slidably arranged on the replacement support, a first driving device used for driving the sliding support to slide is arranged on the sliding support, and a clamping piece used for clamping the fixing shaft is arranged on the sliding support. According to the replacement device, the base is fixed to the horizontal plane below the fixing shaft to be replaced; and the lifting device is started to adjust the height of the clamping piece, a first motor is started to adjust the direction of the clamping piece, a second motor is started to adjust the angle of a control rod, and therefore the clamping piece and the fixing shaft to be disassembled are linearly distributed. The fixing shaft at any height, any position and angle can be placed through the displacement device, the first driving device is started to control the clamping piece to extend to the fixing shaft to be disassembled, the clamping piece clamps the fixing shaft, and the fixing shaft is rotated / pulled to be disassembled.

Description

technical field [0001] The invention relates to a maintenance device for a cast iron machine, in particular to a quick replacement device for a fixed shaft for maintenance of a cast iron machine and a replacement method thereof. Background technique [0002] Iron casting machine is a kind of equipment for casting pig iron blocks in iron workshop, which is composed of endless chain belt equipped with a series of casting moulds. The molten iron is poured into the running mold one by one at one end, and is cooled by spraying water on the way. When the chain belt at the tail of the cast iron machine moves in reverse, the solidified iron pieces will automatically fall off from the mold. [0003] The traditional way to replace the fixed shaft of cast iron machine is to pull out or screw out the fixed shaft manually. The shaft head of the fixed shaft is easy to stick to slag and iron. Therefore, it is difficult, labor-intensive and takes a long time to replace the shaft manually. T...
