Lift truck for replacing or overhauling disconnecting switch

Abstract

A lift truck for replacing or overhauling a disconnecting switch comprises a base, trundles, stand columns, a hand wheel, a left transporting base, a left tackle, a left pulley, beams, a right pulley, a right trolley, a right transporting base, a limit plate and a winch, wherein the trundles are installed on the lower portion of the base, the two stand columns are installed on the left side and the right side on the base, the hand wheel is installed on the lower portion of the left side stand column, the left pulley is installed on the upper portion of the left side stand column, the left transporting base is fixedly connected with the left tackle, and the left tackle is installed on the left side stand column. The winch is installed on the right side of the upper portion of the base, the right pulley is installed on the upper portion of the right side stand column, the right trolley is installed on the right side stand column, the right transporting base is fixedly connected with the right trolley, and two ends of the two beams are welded between the two stand columns. The lift truck for replacing or overhauling the disconnecting switch has the advantages of being simple in principle structure and capable of achieving rising and falling through a hand mode or an electric mode, effectively saving physical power of maintainers and improving overhauling or replacing efficiency of a disconnecting link practically, so that reliability of mains supply is improved.

Description

technical field [0001] The invention relates to a lifting tool, in particular to an isolating switch replacement and overhaul lifting vehicle. Background technique [0002] The overhaul period of the 66 kV isolating switch is 4-5 years. In the actual overhaul work, since the weight of the single switch of each phase has reached more than 65 kg, the maintenance personnel need to lift the single switch by more than two meters during the maintenance process. It is often transported up and down at a high height, and the staff often suffers from muscle strain or the knife switch falls off, which is very easy to cause danger and causes great difficulties to the maintenance work. Contents of the invention [0003] The purpose of the invention is to save the physical strength of the maintenance personnel, avoid the risk of the knife switch falling off, and improve the efficiency of the overhaul and replacement of the knife switch. In particular, it provides an isolating switch rep...
