Abstract
The invention discloses a crane winding drum rope-arranging device. The crane winding drum rope-arranging device comprises a front semiring and a rear semiring which are connected with each other through a connecting sheet, wherein a rope-arranging opening is formed in the front semiring; a plurality of metras screws are arranged on the inner sides of both the front semiring and the rear semiring; each metras screw comprises a screw body; a groove is formed in the middle of each screw body; a spring is mounted in each groove; a steel ball is arranged at the end, close to the end opening of the groove, of the spring. The crane winding drum rope-arranging device can convert the friction relationship between the rope-arranging device and the winding drum from sliding friction to rolling friction, so that the friction between the rope-arranging device and the winding drum is effectively reduced, the abrasion of the rope-arranging device and/or the winding drum is reduced; the metras screws can extend or retract automatically under the pressure of the winding drum, so that a gap cannot be formed between the rope-arranging device and the winding drum, and vibration or noise caused by the gap between the rope-arranging device and/or the winding drum is avoided.
Description
Technical field
The present invention relates to hoisting crane technical field, specifically, relate to a kind of hoist roller rope guide.
Background technology
At present, hoisting crane adopts steel rope that goods is promoted or shifted more, therefore, on the reel of nearly all hoisting crane, have rope guide, current existing rope guide has two kinds of plug helix rope guide and pressing block type rope guides, wherein, plug helix rope guide is to adopt the mode matching with reel plug helix to arrange rope, it is the conventional way of current domestic electric block, and cliding friction between reel plug helix and rope guide disconnects after whole circle casting.This rope guide, due to long-term and reel friction, will produce gap between plug helix and helical tooth, and rope guide easily produces and rocks, and goes down to have noise for a long time, and meanwhile, this rope guide can not be adjusted this gap automatically.And pressing block type rope guide and plug helix rope guide are similar, be also cliding friction, the long-term and reel friction of this rope guide briquetting, very easily causes wearing and tearing, and cord-pressing block needs to manufacture separately, and rope guide ring body needs to process, and cost is relatively high.
For the problem in correlation technique, actv. solution is not yet proposed at present.
Summary of the invention
For the problem in correlation technique, the present invention proposes a kind of hoist roller rope guide, effectively the reduction wear intensity of rope guide and/or reel.
Technical scheme of the present invention is achieved in that
A kind of hoist roller rope guide, comprises the front semi-ring and the rear semi-ring that connect by connecting strap, wherein, the row's of being provided with rope mouthful on described front semi-ring, and the inner side of described front semi-ring and described rear semi-ring is provided with some ripple pearl screws.
Wherein, described ripple pearl screw comprises screw body, and the middle part of described screw body is provided with groove, in this groove, spring is installed, and the one end near described groove port on described spring is provided with steel ball.
Optionally, described some ripple pearl screws are uniformly distributed in described front semi-ring and described rear semi-ring inner side.
Wherein, on described rear semi-ring, be also provided with the bearing being connected with the distance rod on reel.
The present invention is by arranging ripple pearl screw at front semi-ring and rear semi-ring, thereby make the friction law between rope guide and reel become friction of rolling from cliding friction, and then effective reduced the friction force between rope guide and reel, reduce the wear intensity of rope guide and/or reel.
In addition, the present invention is also set to spring and steel ball structure by ripple pearl screw, thereby realize ripple pearl screw under the pressure of reel, can stretch automatically, thereby actv. has prevented from producing gap between rope guide and reel, avoid rope guide and/or reel to rock or noise because gap produces.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain, belongs to the scope of protection of the invention.
As shown in Figure 1-2, according to the hoist roller rope guide of the embodiment of the present invention, comprise the front semi-ring 2 and the rear semi-ring 3 that connect by connecting strap 1, wherein, the row's of being provided with rope mouth 4 on described front semi-ring 2, and the inner side of described front semi-ring 2 and described rear semi-ring 3 is provided with some ripple pearl screws 5.
As shown in Figure 3, in one embodiment, for the structure of ripple pearl screw 5, described ripple pearl screw 5 comprises screw body 6, the middle part of described screw body 6 is provided with groove 7, in this groove 7, spring 8 is installed, and the one end near described groove 7 ports on described spring 8 is provided with steel ball 9.
In the time of practical application, described some ripple pearl screws 5 are uniformly distributed in described front semi-ring 2 and described rear semi-ring 3 inner sides, certainly, in the time of practical application, also can be inhomogeneous distribution, it can design according to actual needs, is all just a kind of optimal case with distributing.
In addition, as shown in Figure 2, in one embodiment, on described rear semi-ring 3, be also provided with the bearing 12 being connected with the distance rod 11 on reel 10.
Understand for convenience technique scheme of the present invention, below by the assembling schematic diagram of the hoist roller rope guide described in the embodiment of the present invention, technique scheme of the present invention is elaborated.
In the time of concrete use, as shown in Fig. 4-5, front semi-ring 2 and rear semi-ring 3 are linked together around reel 10 use connecting straps 1, tighten bolt.Tighten again ripple pearl screw 5 to just withstanding reel 10 plug helixs, install bearing 12 and distance rod 11 with bolt simultaneously, under the effect of bearing 12 and distance rod 11, rope guide can, along with reel 10 rotates and rotates, can only not move on reel 10 axis directions.Rotate and work as lifting mechanism band movable reel 10, the bulb (being steel ball) of the ripple pearl screw 5 on rope guide rolls on reel 10, due to the spiral fluted effect on reel 10, can make rope guide move along axle center, and the row's of playing rope is mobile.
As can be seen here, by means of technique scheme of the present invention, by ripple pearl screw 5 being set at front semi-ring 2 and rear semi-ring 3, thereby make the friction law between rope guide and reel 10 become friction of rolling from cliding friction, and then effective reduced the friction force between rope guide and reel 10, reduce the wear intensity of rope guide and/or reel 10.
In addition, the present invention is also by being set to ripple pearl screw 5 spring 8 and steel ball 9 structures, thereby realize ripple pearl screw 5 under the pressure of reel 10, can stretch automatically, thereby actv. has prevented from producing gap between rope guide and reel 10, avoid rope guide and/or reel 10 to rock or noise because gap produces.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
