Embodiment Construction
[0014] Such as image 3 , 4 As shown, the deflection rope puller is suitable for the rope discharge method relative to the broken line rope groove drum. After wire rope is drawn from broken line rope groove reel, walk around the rope groove of arranging rope pulley 4, then, wind out from rope pulley rope groove. The rope pulley 4 divides the wire rope between the broken line rope groove reel and the rope pulley into two sections with different lengths. The rope pulley 4 slides back and forth on the rope shaft 3 along with the winding of the steel rope on the broken line rope groove reel under the effect of the axial resultant force of the two sections of steel ropes. The upper deflection frame 1 and the clamp 2 installed thereon, the rope shaft 3, the rope pulley 4 and the rope retaining bar 5 also deflect under the effect of two sections of wire ropes relative to the radial resultant force of the rope pulley 4. Whenever the rope pulley 4 slides past the midpoint of the rop...

Abstract
The invention discloses a deflection-type rope arranger belonging to the technical field of engineering machinery, and particularly relates to a rope arranger for assisting a broken-line rope groove winding drum to wind a steel wire rope in multiple layers. The rope arranger is mainly formed by an upper deflection frame, hoops, a rope arrangement shaft, a rope arrangement pulley, rope retaining rods, bolts, a swing bearing, a pin shaft (I), a reset device, a lower bearing frame, a pin shaft (II) and folding type connecting rods. Through controlling the deflection processes of the upper deflection frame, and the hoops, the rope arrangement shaft, the rope arrangement pulley and the rope retaining rods arranged on the upper deflection frame, a rope-feeding deflection angle formed by winding the steel wire rope through the broken-line rope groove winding drum is controlled within the optimal range at any time. Meanwhile, the adverse effect of the steel wire rope vibration on winding the rope is restrained, so that the steel wire rope is protected maximally, the speed of wire fracture and ultimate failure caused by abrasion and plastic deformation is reduced, the problem of rope disorder is solved from the root, and the service life of the steel wire rope is greatly prolonged. The deflection-type rope arranger provided by the invention is characterized by adopting a pure mechanical design without the need for adding other powers, and in addition, being simple in structure, convenient to install, good in stability, high in cost performance, and very applicable to various large-scale winding machines.
Description
technical field [0001] The invention belongs to the technical field of construction machinery, and in particular relates to a rope rower for assisting the multi-layer winding of steel wire ropes by a broken line rope groove reel. Background technique [0002] The broken line rope groove drum can realize the regular multi-layer winding of the wire rope; it can not only ensure the large capacity of the hoisting machinery, but also effectively prolong the service life of the wire rope. Therefore, it has been widely used in the fields of oil drilling, mining industry, building construction, aviation lifting, deep sea exploration and lifting industry; especially the application of double broken line rope groove drum is more common. However, in practical applications, problems such as rapid broken wires, disordered ropes and short-term failures of steel wire ropes often occur, which have many adverse effects on engineering construction. [0003] At present, there are mainly the f...
