Driving mechanism for lifting type buried transformer

Abstract

The invention discloses a driving mechanism for a lifting type buried transformer. The lifting type buried transformer comprises a bearing platform arranged in a pit in a lifting mode and a transformer substation arranged on the bearing platform. The driving mechanism includes a power cylinder, a first driving wheel, a second driving wheel and a driving strip, wherein the power cylinder is arranged in the pit and is positioned on one side of the bearing platform; the first driving wheel is rotatably arranged at an end part of a piston rod of the power cylinder; the second driving wheel is rotatably arranged on an inner side wall of the pit; and the driving strip is in transmission connection with the first driving wheel and the second driving wheel, two ends of the driving strip are connected to the bearing platform and the piston rod respectively, and the driving strip can sequentially wind the first driving wheel and the second driving wheel. According to the driving mechanism, the power cylinder is used for driving lifting, and besides a telescopic stroke of the power cylinder, the driving stroke is increased through cooperation of the first driving wheel, the second driving wheel and the driving strip so that the accumulated driving stroke is matched with the lifting stroke of a transformer substation, and the transformer substation can be smoothly lifted to the ground.

Description

technical field [0001] The invention relates to the field of lift-type buried substations, in particular to a driving mechanism for lift-type buried substations. Background technique [0002] A substation is a place to change the voltage, and converts the high-voltage current delivered by the power plant into a low-voltage current for users. Therefore, the substation is generally installed in a crowded place. For safety considerations, lift-type underground substations are generally used, and the substation can be lifted and lowered in the pit, and its safety performance is relatively high. [0003] At present, for lift-type underground substations, the substation is usually set on a scissor-type lifting platform, and the scissor-type lifting platform drives the substation to realize lifting. However, the scissor lift platform has a complex structure and high cost, and it is difficult to install in the pit. Therefore, people consider using a power cylinder to drive the lift...

AI Technical Summary

Problems solved by technology

However, the scissor lift platform has a complex structure and high cost, and it is difficult to install in the pit. Therefore, people consider using a power cylinder to drive the lifting of the load-bearing platform.

However, due to the need to accommodate the entire substation, the depth of the pit is usually relatively deep, and because the power cylinder itself has a certain height, the telescopic stroke of the piston rod cannot match the lifting stroke of the substation, resulting in the inability to install the substation. smoothly ascended to the ground
