Abstract

The invention discloses a floating device for an aerial work platform. The floating device of the aerial work platform of the present invention includes: a pressure oil source, a controller left floating device, a right floating device, a vehicle frame and a swing bridge, the left floating device includes a left hydraulic cylinder, a left balance valve and a left locking device, and the right floating device Including the right hydraulic cylinder, right balance valve and right locking device, one end of the left hydraulic cylinder and one end of the right hydraulic cylinder are hinged on the frame; the swing bridge is hinged with the frame, the other end of the left hydraulic cylinder is connected to the other end of the right hydraulic cylinder Relatively hinged at both ends of the swing bridge. The left locking device and the right locking device constitute the second layer of locking of the left hydraulic cylinder and the right hydraulic cylinder to ensure that the oil cylinder will not slide, and the aerial work platform will not tip over due to the oil cylinder sliding.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a floating device of 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. Move the platform car to a suitable position, adjust the platform car to the level, and then fix the platform car for lifting. One function that the aerial work platform needs to rely on during the moving process and adjustment to the level is the whole vehicle floating of the aerial work platform. [0003] The floating of the whole vehicle of the high-altitude platform is realized by adding a floating oil cylinder to the swing bridge. One end of the oil cylinder is connected to the frame, and the other end is connected or...
