Abstract
A floating device for an aerial work platform, comprising a pressure oil source (100), a controller (200), a left floating device, and a right floating device, a chassis (700), and a swing axle (600). The left floating device comprises a left hydraulic cylinder (300), a left balance valve (310), and a left locking device; the right floating device comprises a right hydraulic cylinder (400), a right balance valve (410), and a right locking device; one end of the left hydraulic cylinder (300) and one end of the right hydraulic cylinder (400) are hinged on the chassis (700); the swing axle (600) is hinged with the chassis (700); the other end of the left hydraulic cylinder (300) and the other end of the right hydraulic cylinder (400) are hinged on two opposite ends of the swing axle (600); and the left locking device and the right locking device constitute second-level locking of the left hydraulic cylinder (300) and the right hydraulic cylinder (400), thereby ensuring that the aerial work platform will not tip over due to the sliding of the hydraulic cylinders.
