The invention provides a main coil steel wire rope anti-winding device for a large bridge crane. The main coil steel wire rope anti-winding device comprises a steel wire rope blocking assembly used for being mounted between a balance stand and steel wire ropes on the inner side of the balance stand in order to prevent the steel wire ropes on the inner side of the balance stand from being wound around the balance stand during tank retaining. The steel wire rope blocking assembly comprises fixed blocking frames used for being mounted on the outer side faces of pulley block bases at the two endsof a hook table of the bridge crane, and movable blocking frames used for being connected with the two fixed blocking frames in an inserted manner. A frame structure used for encircling all the steelwire ropes on the inner side of the balance frame is formed by the fixed blocking frames and the movable blocking frames. According to the main coil steel wire rope anti-winding device for the large bridge crane, the steel wire rope blocking assembly is arranged between the balance stand and the steel wire ropes, it can be avoided that the steel wire ropes are damaged when the steel wire ropes arewound around the balance stand during tank retaining, and the main coil steel wire rope anti-winding device is simple in structure, convenient to mount and low in use cost.
Description
technical field [0001] The invention relates to the technical field of crane installation, and more specifically, relates to a main winding wire rope anti-winding device for a large bridge crane. Background technique [0002] As we all know, the bridge crane is a kind of lifting device for lifting heavy objects such as tanks. Because of its appearance as a bridge structure, and symmetrically arranged lifting lugs are installed at the bottom of the bridge structure, relying on the hanging function of the lifting lugs, Hoist heavy objects such as tanks to the transport vehicle. However, at the moment when the tank is placed on the transport vehicle (commonly known as "sitting the tank"), the steel wire rope on the inside of the bridge is bent due to sudden looseness, and then it is wound on the balance frame, and it is very easy to break due to the operation of the bridge crane. If the wire rope is broken, it is not only expensive, but also has a long procurement cycle and is...
