Background
The cylinder for the high-voltage switch is used as one of the devices in the high-voltage switch device, no matter a spiral welded pipe or an extruded pipe is adopted, sharp-angled burrs and metal foreign bodies cannot be arranged on the inner wall of the cylinder, otherwise the sharp-angled burrs and the metal foreign bodies easily cause discharge in a high-voltage occasion, the insulativity of the cylinder is seriously influenced, and therefore the inner wall of the cylinder needs to be polished. However, the length of the cylinder body usually reaches dozens of meters, the inner diameter of the cylinder body is small, and an operator cannot enter the cylinder body, so that the inner wall of the cylinder body needs to be polished by the aid of the device.
For example, the device for cleaning the inner wall of the cylinder disclosed in chinese patent application publication No. CN107088561A includes a supporting shaft (i.e., a supporting rod), and a cleaning brush portion (i.e., a polishing disc assembly) is provided at intervals on the circumferential surface of the supporting shaft. Still the interval is provided with three centering supporting mechanism (promptly supporting mechanism) around the back shaft on the global of back shaft, and centering supporting mechanism includes walking wheel (promptly gyro wheel) and connects walking wheel and the epaxial bracing piece of back (promptly connecting rod), and the walking wheel is connected with the bracing piece through setting up at the terminal spring of bracing piece, and realizes the extrusion contact of walking wheel and barrel inner wall through the spring that sets up. And a driving mechanism (namely a rotary power mechanism) is also arranged at the end part of the supporting rod, and the driving mechanism is in transmission connection with the cleaning brush part and is used for driving the cleaning brush part to rotate so as to realize the polishing of the inner wall of the cylinder body.
However, the cylinder body applicable to the centering support mechanism in the device is limited, and due to the limitation of the expansion amount of the spring, when the inner wall of the cylinder body with an excessively large inner diameter is polished, the travelling wheel cannot be in contact with the inner wall of the cylinder body, the cleaning brush part cannot be supported, and further polishing of the inner wall of the cylinder body cannot be performed; when the inner walls of the cylinders with small inner diameters are polished, the springs are over-compressed, even the whole device cannot enter the cylinders, the service life of the springs and the smooth movement of the centering support mechanism are influenced, and even the inner walls of the cylinders cannot be polished.
