AI Technical Summary

Problems solved by technology

(1) Enlarge the reel and increase the diameter of the reel. After adopting this method, the height of the crane will increase correspondingly. The height of the factory building is also affected
(2) The method of lengthening the drum is simple and effective, but the width or length of the crane must also be adjusted according to the length of the drum, which affects other structures of the crane
However, the structure of this type of reel is simple, and the phenomenon of rope disorder will occur when the steel wire rope is wound more than two layers, which cannot meet the requirements.
The double-folding reel can be wound in multiple layers, which can be applied to ordinary lifting equipment (steel wire rope winding is relatively stable within six layers), but for lifting equipment with large tonnage and high lifting height, it is necessary to wind more than 10 layers of wire rope Due to the accumulation of errors, the phenomenon of disordered ropes is relatively common, which seriously affects the safety performance of lifting equipment.

Abstract

The invention discloses an ultra-large rope capacity coiling drum which mainly resolves the problems of rope mess and complex structure production and the like. The ultra-large rope capacity coiling drum comprises a coiling shaft, two ends of the coiling shaft are provided with a left baffle plate and a right baffle plate in a relatively parallel mode, the coiling shaft is provided with a shaft rope groove, the inner side of the left baffle plate and the inner side of the baffle are both provided with arc parallel grooves, and the arc parallel grooves are distributed at equal intervals. The inner side of the left baffle plate is further provided with a left reversing guide platform which is a double-folding-line rope groove, the corresponding position of the right baffle plate is provided with a right reversing guide platform in a mapping mode, and the right reversing guide platform is also a double-folding-line rope groove. The coiling drum can effectively avoid accumulation errors occurring during multi-layer steel wire rope coiling, rope mess cannot occur even if 20 layers of ropes are coiled on the double-folding-line drum, and the problem that rope mess of the ultra-large rope capacity coiling drum is effectively resolved. In addition, the ultra-large rope capacity coiling drum has the advantages of being low in cost, high in safety and the like.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a reel with a super large rope capacity. Background technique [0002] Lifting equipment is an industry that is closely related to the national economy and the people's livelihood such as urban construction, transportation, and energy development. The reel is an important load-bearing part of the crane. It winds the wire rope through the function of the reducer to realize the lowering or lifting of the lifting weight. It carries the lifting load, retracting and unwinding the wire rope, and the lifting of the object device. Its safety and reliability are very important. It is one of the most important and core components of crane machinery. With the large-scale of modern engineering, the hoisting machinery is also developing towards large-scale, its lifting weight and lift are greatly increased, and the lift can reach hundreds of meters or even thousands of meters, thus put...
