Angle-adjustable crane goods stabilizing system

Abstract

The invention discloses an angle-adjustable crane goods stabilizing system. The angle-adjustable crane goods stabilizing system comprises a guide rail, a walking guide car, a car traction mechanism and a lifting weight stabilizing mechanism; the guide rail is arranged in the length direction of a lifting arm, and is fixed on the lifting arm; the walking guide car is slidingly arranged on the guide rail, and can freely slide along the guide rail; the walking guide car is driven to slide up and down along the guide rail by the car traction mechanism; and the lifting weight stabilizing mechanism includes a constant-tension goods stabilizing winch, a first goods stabilizing guide pulley, a second goods stabilizing guide pulley, a first car goods stabilizing guide pulley, a second car goods stabilizing guide pulley and a goods stabilizing steel wire rope. Through change of the position of the walking guide car mounted on the lifting arm, the rope outlet angle of the goods stabilizing steel wire rope can be conveniently adjusted to keep an optimal goods stabilizing angle and proper steel wire rope tension.

Description

technical field [0001] The invention relates to a cargo stabilizing system, in particular to an angle-adjustable crane stabilizing system. Background technique [0002] Large-scale cranes used in offshore engineering hoisting operations are usually equipped with a cargo stabilization system to prevent excessive swinging of equipment or cargo when hoisting important or large equipment (cargo). For boom luffing cranes, the current common solution is to install a constant tension cargo stabilizing winch at the root of the boom or at the front of the turntable, and then lead out the cargo stabilizing wire rope through a set of fixed guide pulleys on the boom and connect it to the hoisted crane. On the equipment or cargo, the anti-swing of the cargo is realized by retracting and unwinding the steel wire rope action of the cargo stabilizing winch. Although this type of scheme has a simple structure and low manufacturing cost, it has the following insurmountable problems: Since th...

Problems solved by technology

Although this type of scheme has a simple structure and low manufacturing cost, it has the following insurmountable problems: Since the outlet point of the cargo-stabilizing wire rope is fixed, when the working angle of the boom and the lifting height of the equipment (or cargo) change, the cargo-stabilizing wire rope The angle between the equipment (or cargo) varies greatly, and when the angle between the two is too small, the cargo stabilization system hardly works
