Rope arrangement assisting device and crane

Abstract

The invention discloses a rope arrangement assisting device and a crane. The rope arrangement assisting device comprises a roller component arranged on a lifting beam of the crane, and a driving mechanism, wherein the roller component at least comprises a first roller and a second roller; a clearance for allowing the steel wire rope of the crane to pass through is reserved between the first roller and the second roller, and the clearance is adjustable; the driving mechanism is used for driving the first roller and / or the second roller to rotate towards a pretension direction; the pretension direction is the direction of friction force for enabling the first roller and / or the second roller to produce a friction force, deviating from the winding direction, to a steel wire rope. The rope arrangement assisting device enables rope arrangement force of a steel wire rope to be increased, so as to enable the steel wire rope to have low possibility of rope chaos and rope climbing. Therefore, the weight of a hook is reduced, the load suspending performance of the crane can be improved, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a rope arrangement auxiliary device and a crane. Background technique [0002] Crane is a kind of construction machinery capable of lifting, transporting and loading and unloading materials. It is widely used in construction, transportation, ports, energy and farmland water conservancy and other fields, such as building bridges, installing power generation equipment, shipbuilding, and erecting wind power. generator set etc. [0003] The wire rope is one of the important parts of the crane to realize the hoisting. After it is wound on the winch, it goes around the boom and accepts the heavy object by setting the hook. During the construction process, the steel wire rope is prone to rope disorder and rope climbing. The main reason is that the steel wire rope does not have enough rope pulling force, that is, when the hook is empty or the hook is on the ground, the tension of th...

Problems solved by technology

[0004] In addition, the angle of the rope arrangement does not meet the optimum angle range of the reel, which is also one of the reasons for the occurrence of rope chaos and rope climbing

In this case, under certain arm length conditions, the steel wire rope on the drum does not meet the optimum rope entry angle. If the ratio is not in the appropriate range, it will also cause chaos and rope climbing.
