Anti-groove leaping protector for pitching steel cable of ship unloader

Abstract

The invention relates to a groove leaping safety device for a pitching steel cable of a ship unloader. In the device, one end of the steel cable is connected to a first drum and then winded around a first pulley group, a first deflection pulley, a second deflection pulley and a second pulley group in turn to be connected to a second drum. The device is characterized in that: an anti-groove leaping pulley is arranged on a first bracket and a second bracket through a pulley shaft, a bearing, a first shaft sleeve and a second shaft sleeve, and the first and second brackets are welded on the bracket of a top pulley group; and the shaft end of the anti-groove leaping pulley is provided with a rotation stopper to prevent the rotation of the pulley shaft. In the invention, when the main beam is lifted upwards, the groove leaping of the steel cable at the position of the top pulley is prevented and the safety accidents caused by the breakage of the steel cable resulting from the fact that groove leaping of the steel cable is not found and handled instantly; and the anti-groove leaping device adopts the pulley, so that when the main beam is lifted upwards, the steel cable dose not rub with the anti-groove leaping device, and the damage and waste of the steel cable caused by friction are avoided.

Description

technical field [0001] The device of the invention belongs to the technical field of engineering machinery, and relates to a safety device for preventing a ship unloader from pitching a steel wire rope from jumping. Background technique [0002] With the development of the economy, the construction of the port is also developing rapidly, and the demand for ship unloaders is also increasing; in some large seaports, due to the high height of seagoing ships, some seagoing When entering the port, it is easy to collide with the main girder of the ship unloader to cause safety accidents, so the ship unloader must be pitched and adjusted according to the height of the seagoing ship; In technology, the device for preventing wire rope hopping is mainly to add a shield at the pulley to prevent the wire rope from hopping, but for the pitching mechanism of the ship unloader, the wire rope at the top pulley of the ship unloader is still very prone to job hopping when the main beam is pi...
