Abstract
The invention provides a steel wire rope skipping preventive device for a winding drum of a crane. The steel wire rope skipping preventive device at least comprises a support and a pressure lever arm fixedly supported on the support through a bolt. The pressure lever arm comprises a horizontal pressure lever arm and a vertical pressure lever arm, the horizontal pressure lever arm extends out of the support and is disposed above the winding drum, and the vertical pressure lever arm is arranged above a limiting switch. Since the pressure lever arm is arranged on the support and one end of the pressure lever arm is arranged above the winding drum while the other end of the pressure lever arm is arranged above the limiting switch in the support, skipping of steel wire ropes on the winding drum of the crane can be effectively prevented, abrasion of the steel wire ropes can be lessened, and the service life of the steel wire ropes is prolonged.
Description
Technical field
The present invention relates to crane assemblies machinery, relate in particular to a kind of anti-steel rope Skipping-rope device of reel of hoisting crane.
Background technology
As everyone knows, hoisting crane generally twines around the surface of reel through adopting reel under the driving of electrical motor, to rotate and driving steel rope, thereby mentions article through steel rope.Yet, steel rope when reel twines, possibly take place to intersect or twine irregular, thereby produce the phenomenon of rope skipping.Will aggravate the wearing and tearing of steel rope like this, shorten the service life of steel rope.
In view of this, be necessary the reel of hoisting crane is improved, to address the above problem.
Summary of the invention
The object of the present invention is to provide a kind of anti-steel rope Skipping-rope device of reel of hoisting crane, it can prevent effectively that the steel rope on the reel of hoisting crane from rope skipping phenomenon taking place when twining, reduce the wearing and tearing of steel rope, improves the service life of steel rope.
For realizing the foregoing invention purpose, the present invention provides a kind of anti-steel rope Skipping-rope device of reel of hoisting crane, and it comprises at least:
Support, and
Be immobilizated in the depression bar arm of said support through a latch, said depression bar arm comprises a horizontal struts arm and a vertical depression bar arm, and said horizontal struts arm extends said support and is arranged at the top of reel, and said vertical depression bar arm is arranged at the top of a limit switch.
As further improvement of the present invention, said horizontal struts arm and the orthogonal setting of vertical depression bar arm.
As further improvement of the present invention, said anti-Skipping-rope device also comprises a control apparatus, and it extends into said support, and with the mutual butt of said horizontal struts arm.
Compared with prior art, the invention has the beneficial effects as follows: a depression bar arm is set in support, and the one of which end is arranged at the reel top, and an end is arranged at the limit switch top in the support.Through such structure, can prevent effectively that the steel rope on the reel of hoisting crane from rope skipping phenomenon taking place when twining, thereby can reduce the wearing and tearing of steel rope, and the service life of improving steel rope.
Description of drawings
Fig. 1 is the front elevation in anti-steel rope Skipping-rope device one specific embodiment of the reel of a kind of hoisting crane of the present invention;
Fig. 2 is the cutaway view of anti-steel rope Skipping-rope device of the reel of a kind of hoisting crane shown in Fig. 1.
The specific embodiment
Below in conjunction with each embodiment shown in the drawings the present invention is elaborated; But should be noted that; These embodiments are not limitation of the present invention; The function that those of ordinary skills do according to these embodiments, method, or structural equivalent transformation or substitute all belong within protection scope of the present invention.
Join the specific embodiment of anti-steel rope Skipping-rope device of the reel of a kind of hoisting crane of the present invention shown in Figure 1.In this embodiment; A kind of anti-steel rope Skipping-rope device 100 of reel 10 of hoisting crane; It comprises at least: support 30, and be immobilizated in the depression bar arm 70 of said support 30 through a latch 703, said depression bar arm 70 comprises a horizontal struts arm 701 and a vertical depression bar arm 702; Said horizontal struts arm 701 extends said support 30 and is arranged at the top of reel 10, and said vertical depression bar arm 702 is arranged at the top of a limit switch 60.
In conjunction with shown in Figure 2, in this embodiment, this anti-Skipping-rope device 100 also comprises a control apparatus 50, and it extends into said support 30, and with said horizontal struts arm 701 mutual butts.In this embodiment, this control apparatus 50 can be bolt.
Steel rope (not shown) can twine round reel 10 under the driving of electrical motor (not shown), and carries out the winding operation of individual layer steel rope round the surface 101 of reel 10.In this embodiment, the minor increment between the surface 101 of horizontal struts arm 701 and reel 10 is 1.2 ~ 1.5 times of the wirerope diameter that twines of reel 10, and is no more than 2 times at most.Support 20 can be fixed in the base 20.
In this embodiment, this limit switch 60 can be regulated through control apparatus 50 with the distance between the vertical depression bar arm 702, with the use of the steel rope that adapts to different-diameter.Take place to intersect or twine when irregular when steel rope twines on the surface 101 of reel 10; Steel rope can push horizontal struts arm 701 vertically upward; And utilize lever principle through latch 703, will drive vertical depression bar arm 702 and move down, thereby trigger limit switch 60.This limit switch 60 can send washout; Thereby the electrical motor that drives reel 10 is stopped operating; Thereby prevent when steel rope from twining on the surface 101 of reel 10 to take place to intersect or twine the generation of rope skipping phenomenon when irregular effectively; Thereby can reduce the wearing and tearing of steel rope, and improve the service life of steel rope.
The listed a series of detailed description of preceding text only is specifying to feasibility embodiment of the present invention; They are not in order to restriction protection scope of the present invention, allly do not break away from equivalent embodiment or the change that skill of the present invention spirit done and all should be included within protection scope of the present invention.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and under the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, scope of the present invention is limited accompanying claims rather than above-mentioned explanation, therefore is intended to the implication of the equivalents that drops on claim and all changes in the scope are included in the present invention.Should any Reference numeral in the claim be regarded as limit related claim.
In addition; Describing according to embodiment though should be appreciated that this specification sheets, is not that each embodiment only comprises an independently technical scheme; This narrating mode of specification sheets only is for clarity sake; Those skilled in the art should make specification sheets as a whole, and the technical scheme among each embodiment also can form other embodiments that it will be appreciated by those skilled in the art that through appropriate combination.
