Abstract

The invention discloses a floating device of an aerial work platform. The floating device of the aerial work platform comprises a pressure oil source, a controller, a left floating device, a right floating device, a frame and a swing bridge, wherein the left floating device comprises a left hydraulic cylinder, a left balance valve and a left locking device, and the right floating device comprises a right hydraulic cylinder, a right balance valve and a right locking device; one end of the left hydraulic cylinder and one end of the right hydraulic cylinder are hinged to the frame; the swing bridge is hinged to the frame; and the other end of the left hydraulic cylinder and the other end of the right hydraulic cylinder are oppositely hinged to the two ends of the swing bridge. The left locking device and the right locking device form second-layer locking of the left hydraulic cylinder and the right hydraulic cylinder, it is guaranteed that an oil cylinder cannot slide, and the aerial work platform cannot tip over due to the sliding of the oil cylinder.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a floating device for an aerial work platform. Background technique [0002] The aerial work platform is a lifting mechanical equipment used for aerial work maintenance. The product has the characteristics of stable structure, flexible movement, stable lifting, convenient operation, and large load capacity, which provides convenience for aerial work units. When the aerial work platform is working, first Move the platform truck to a suitable position, adjust the platform truck to the level, and then fix the platform truck for lifting operations. One function that the aerial work platform depends on during the movement process and adjustment to the level process is the complete vehicle float of the aerial work platform. [0003] The floating of the whole vehicle on the high-altitude platform is realized by adding a floating oil cylinder to the swing bridge. One end of the oil ...
