Abstract
The utility model discloses a winding drum with high rope capacity. The winding drum comprises a winding drum body, an end plate at the rope inlet end and a baffle on the other side. A lebus is formed in the winding drum body. A rope inlet gap is formed in the winding drum body or the end plate at the rope inlet end. The end plate at the rope inlet end and the inner side face of the baffle are further respectively provided with the first layer to the mth layer of rope compensation protrusions which are concentrically distributed from inside to outside, wherein m is the maximum number of winding layers of the winding drum. Each layer of rope compensation protrusions are composed of A side protrusions which are arranged on the end plate at the rope inlet end and B side protrusions which are arranged on the baffle. The protruding heights of the rope compensation protrusions and the outer diameters of concentric circles where the rope compensation protrusions are located regularly change according to the winding directions and the diameters of steel wire ropes, so that when being wound on the winding drum, the steel wire ropes at all the layers are restrained between the end plate at the rope inlet end and the baffle by the rope compensation protrusions at the corresponding layers. The winding drum is simple in structure and especially suitable for a hoisting mechanism in which an ultra-long steel wire rope needs to be wound, and by the adoption of the winding drum, the ropes are not disarranged when being wound by multiple layers, an old winding drum can be improved, and a new winding drum can be designed.
Description
Technical field
The utility model relates to a kind of reel, especially a kind of great Rong rope amount reel.
Background technology
The performance of lifting mechanism is directly determining the performance of tower crane, and reel is the critical elements of lifting mechanism.At present, along with the economic development of China, super-high buildings is more and more.Build super-high buildings and need use large-scale superelevation tower crane.And the lifting mechanism of tower crane needs the overlength steel rope, generally, all at 1000m～2000m, due to the restriction of each side, the overlength steel rope can only take to carry out multiple wraps on reel, the general number of turns that is wound around, all more than 8 layers, solves the coiling problem of overlength steel rope on reel.
For multilayer is counted reel, row's rope disorder cable problem is a difficult problem in the industry always.
In industry, generally adopt at present processing fold line grooves on reel to solve row's rope problem, the fold line grooves of each circumference is comprised of the first straight-line groove section, first fold wire casing section, the second straight-line groove section and the second broken line groove section that connect successively, steel rope winding reel one week, complete and move axially a pitch by two broken line groove sections.But in actual use, the broken line slot reel can only guarantee at most not disorder cable of 4 layers of long steel rope of about 500m, after surpassing 4 layers, steel rope will be misaligned, also there will be the disorder cable phenomenon, not only aggravated the wearing and tearing of steel rope, reduce the life-span of steel rope, increased the use cost of tower machine, and weight lifting is unstable, also can causes that skipping of steel wire rope goes out the problems such as reel is outer, serious meeting causes contingency, and the safety in utilization of tower crane is had to material impact.In addition, also have in industry and adopt the servo row system of restricting, but this system bulk weight is large, has additionally increased manufacturing cost, the Installation and Debugging trouble.
Analysis according to the present inventor, the broken line slot reel still occurs that the reason of disorder cable is: owing between steel rope layer and reel two end-stopping plates, having gap, steel rope is on reel during multiple wraps, steel rope easily because the baffle plate gap make between the steel rope of same layer near that circle looseness of steel wire ropes of baffle plate, misaligned.
The utility model content
In order to overcome the deficiency of existing multilayer reel row rope disorder cable, technical problem to be solved in the utility model be to provide a kind of arrange rope neat can be multilaminate coiled great Rong rope amount reel.
The utility model solves the technical scheme that its technical matters adopts: great Rong rope amount reel, comprise spool body, enter the baffle plate of end end plate and opposite side, spool body or enter on the end end plate to be provided with into the rope breach, on spool body, be provided with at the fold line grooves entered between end end plate and baffle plate, fold line grooves comprises grooving linear portion and the grooving broken line be crisscross arranged, enter on the medial surface of end end plate and baffle plate all also to be provided with separately and be respectively ground floor from inside to outside until the benefit rope projection m layer and that distribute with one heart, the maximum Winding Layer that wherein m is reel, every one deck is mended the rope projection and is formed by the B side projection that is arranged on the A side projection on the end end plate and be arranged on baffle plate, each is mended the protruding concentrically ringed external diameter of hill height and place thereof of rope and changes according to the winding direction of steel rope and the diameter rule of steel rope, while making each layer of wirerope-winding on reel, benefit rope projection by equivalent layer constrains between end end plate and baffle plate.
It is definite like this that described ground floor is mended the protruding hill height of rope, in the part corresponding to the breach that enters to restrict, do not mend the rope projection, and hill height is zero; In the part corresponding to the grooving linear portion, it is identical that hill height keeps; In the part corresponding to the grooving broken line, hill height is with wirerope-winding direction monotone variation.
It is definite like this that the described second layer～m layer is mended the protruding hill height of rope, and in the part corresponding to the grooving linear portion, it is identical that hill height keeps; In the part corresponding to the grooving broken line, the hill height dullness is decreased to mends the protruding end of rope.
Defining the concentrically ringed external diameter in the described n layer benefit protruding place of rope is Rn,
Rn=D
