Abstract
The utility model provides a crane device capable of preventing a steel wire rope from skipping. The crane device at least comprises a bracket and a press lever arm, wherein the press lever arm is fixedly clamped on the bracket through an inserting bolt and comprises a horizontal press lever arm and a vertical press lever arm, the horizontal press lever arm extends out of the bracket and is arranged above a reel, and the vertical press lever arm is arranged above a limit switch. According to the crane device disclosed by the utility model, the press lever arm is arranged in the bracket, one end of the press lever arm is arranged above the reel and the other end of the press lever arm is arranged above the limit switch in the bracket, so that the steel wire rope of the reel of a crane can be effectively prevented from skipping during winding, the abrasion of the steel wire rope can be reduced and the service life of the steel wire rope is prolonged.
Description
Technical field
The utility model relates to crane assemblies machinery, relates 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.
The utility model content
The purpose of the utility model is to provide a kind of anti-steel rope Skipping-rope device of reel of hoisting crane, and 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 above-mentioned utility model purpose, the utility model 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 the further improvement of the utility model, said horizontal struts arm and the orthogonal setting of vertical depression bar arm.
As the further improvement of the utility model, 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 beneficial effect of the utility model is: 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 reel of a kind of hoisting crane of the utility model;
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 utility model is elaborated; But should be noted that; These embodiments are not the restriction to the utility model; The function that those of ordinary skills do according to these embodiments, method, or structural equivalent transformation or substitute all belong within the protection domain of the utility model.
Join the specific embodiment of anti-steel rope Skipping-rope device of the reel of a kind of hoisting crane of the utility model 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 the feasibility embodiment of the utility model; They are not the protection domain in order to restriction the utility model, allly do not break away from equivalent embodiment or the change that the utility model skill spirit done and all should be included within the protection domain of the utility model.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and under the situation of spirit that does not deviate from the utility model or essential characteristic, can realize the utility model with other concrete form.Therefore; No matter from which point; All should regard embodiment as exemplary; And be nonrestrictive, the scope of the utility model 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 utility model.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.
