Abstract

The invention relates to the technical field of engineering equipment, and provides a movable balance weight lifting device, a method and engineering machine for controlling the device. The movable balance weight lifting device comprises a rotary table (1), a lifting oil cylinder (10) and a locking mechanism; a cylinder barrel of the lifting oil cylinder (10) is fixed to the rotary table, and a lifting piston rod (5) of the lifting oil cylinder is connected with a balance weight (2); a first through hole (11) is formed in the lifting piston rod; the locking mechanism comprises a safety pin (6), and the safety pin is provided with a locking position and an unlocking position, the locking position is inserted into the first through hole to lock the lifting piston rod after the balance weightis lifted to the designated position, and the unlocking position is separated from the first through hole to enable the lifting piston rod to drive the balance weight to move. According to the movable balance weight lifting device and the engineering machine, the lifting oil cylinder can be mechanically locked after the balance weight is lifted to the designated position, and the locking mode ismore reliable.

Description

technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a movable counterweight lifting device, a method for controlling the device and construction machinery. Background technique [0002] At this stage, with the increase in the number of cranes in our country, the safety of crane operations has attracted more and more attention. Counterweight is an important part of wheeled construction machinery, especially large-tonnage cranes often use movable counterweights. When transferring, it is transported separately from the crane, and then lifted to the designated position by the lifting cylinder of the crane itself during operation. Usually, the cylinder barrel of the lifting cylinder is fixed on the turntable, and the movable counterweight moves up and down with the piston rod of the lifting cylinder to realize lifting and lowering. After the movable counterweight is lifted in place, the relative position between the pis...
