Description

Winch maintenance lifting platform Technical Field The utility model relates to a winch maintenance lifting platform, in particular to a winch maintenance lifting platform, and belongs to the technical field of winch maintenance lifting platforms. Background The winch is core lifting equipment in industries such as mines, ports, buildings, petroleum drilling and the like, is mainly used for heavy object traction, personnel transportation or material lifting (such as mine hoist, port hoisting winch and building construction hoist), has complex working environment, and long-term high-load operation, so that mechanical parts (such as steel wire ropes, braking devices, transmission gears and bearings) are easy to wear, break, rust and the like, and the winch needs to be regularly maintained and overhauled, and according to statistics, the annual failure downtime of the mine winch in China accounts for about 15% -20%, wherein the downtime due to low maintenance efficiency and insufficient safety accounts for more than 40%, and the production efficiency and the operation safety are directly influenced. The winch maintenance needs personnel to approach core components (such as a roller, a reduction gearbox and a head sheave group) to disassemble, detect or replace, the traditional maintenance mode relies on manual construction of a scaffold, a simple elevator or general lifting equipment, however, the traditional scaffold needs manual layer-by-layer construction, the stability is poor, the simple elevator does not have anti-falling protection, personnel falling accident frequency occurs, the winch maintenance also often involves narrow space, high-altitude operation or dust/greasy dirt environment, manual handling tools and parts need climbing or by means of unstable ladders, and personnel fatigue and misoperation (such as bolt leakage and tool falling hurt people) are easily caused.
