Description

Novel anti-swing device for lifting appliance

Technical Field

The utility model relates to a harbour container handling equipment technical field, especially a novel hoist anti-swing device.

Background

The quay crane is a container loading and unloading device arranged at a port and a wharf, a container is hoisted by utilizing a trolley hoist, and the trolley moves on a quay crane girder to realize the loading and unloading of the container. The shore bridge directly works on the ship, and the loading and unloading efficiency and the operation safety of the shore bridge directly influence the loading and unloading capacity of the port and the wharf. At present, the stacking layer number of container in the container ship is more and more big, and for satisfying the operation requirement, the height of bank bridge is also more and more high, at the in-process that bank bridge dolly hoist frequently takes off and land, receives the influence of start-up braking and external environment, and the dolly hoist can take place to sway, has greatly influenced the handling efficiency and the operation safety of bank bridge, and the bank bridge highly big more, the difficult control more of rocking of dolly hoist.

At present, two main ways of preventing a lifting appliance of lifting equipment from swinging are available, one is an eight-rope anti-swinging way, and the other is an electronic anti-swinging way. Eight ropes prevent shaking and utilize wire rope to control the rocking of hoist, and wire rope both need to undertake the effect of restriction hoist and sway, still need to drive the hoist and rise or descend, and the wire rope that prevents shaking is the bearing rope. The eight-rope anti-swing method is complex in winding, a steel wire rope with large length needs to be used, meanwhile, the anti-swing steel wire rope bears the weight, when the lifting appliance swings, the friction of a steel wire inside the steel wire rope is large, and the influence on the service life of the steel wire rope and the service life of the structure is large. In order to reduce the influence on the service life of the steel wire rope as much as possible, the eight-rope anti-rolling device is generally applied to a portal crane with a small height, such as a field bridge. The height of the shore bridge is far greater than that of the field bridge, and the eight-rope anti-shaking mode is not suitable for the shore bridge.

The electronic anti-swing mode collects the information of the lifting appliance by using various sensors and detection elements, processes the collected data by using a computer of the control background, calculates optimal control parameters, feeds the optimal control parameters back to a control system of the trolley, corrects the swing of the lifting appliance and controls the swing amplitude of the lifting appliance. Although the electronic anti-swing mode realizes the control of swing of the lifting appliance, in practical application, the lifting appliance needs frequent lifting and falling, certain friction can be generated in the operation process of the lifting appliance, the operation data of the lifting appliance changes frequently, the operation data of the trolley is adjusted too frequently, the loading and unloading efficiency of a shore bridge and the operation of a driver of the shore bridge are influenced, the initial investment and the maintenance cost of control equipment are high, and the popularization and the use are not facilitated. Therefore, a novel anti-swing device for a shore bridge lifting appliance needs to be developed.
