Abstract
The utility model relates to a power-off device for the limit protection of a steel wire rope. The device comprises a machine table and is characterized in that a rotatable link rod, a limit switch which is pressed against the link rod and a spring for resetting are fixedly arranged on the machine table, wherein the free end of the spring is fixedly connected with a guide plug pin; and the guide plug pin is accommodated on the link rod. By the power-off device, a diagonal angle and a state of winding the steel wire rope on a winding drum are monitored, and power-off protection is carried out in an abnormal situation, so that safe accidents are avoided.
Description
Technical field
The utility model has related to the steel-wire rope type electric block field, has especially related to a kind of breaker device that is used for the limit protection of steel rope.
Background technology
Along with the development of cucurbit technology, no matter being aspects such as structure or material, all constantly innovating and development rope guide, CD type used for electric hoist rope guide is the rope guide that China uses the earliest; Structure is complicated, processing, and mounting or dismounting, maintenances etc. are all not good; Rope guide has the nodular cast iron manufacturing and wear-resisting, simple in structure, and mounting or dismounting are convenient; The rope conductor rope of coming in and going out is steady, is a kind of desirable rope guide that uses, and tiltedly draws protection to be no more than 15 degree.
The rope guide of steel rope cucurbit of the prior art only has guiding steel wire and restricts away along device, excessively tiltedly draw in the use rope guide to damage easily and cause use dangerous.
The utility model content
The purpose of the utility model is to overcome above-mentioned technical matters, and a kind of breaker device that is used for the limit protection of steel rope is provided, and it realizes that steel rope twines unlikely disorder, has improved work efficiency greatly.
The technical scheme that the utility model adopted is:
A kind of breaker device that is used for the limit protection of steel rope; It comprises board; It is characterized in that; Limit switch that on said board, is installed with rotating link rod, compresses each other with said link rod and the spring that is used to reset, the also affixed guiding latch of the free end of said spring, said guiding latch is put and is dissolved on the said link rod.
Aforesaid a kind of breaker device that is used for the limit protection of steel rope is characterized in that, around said board, also is installed with the spacing anti-collision body that is used to compress said link rod.
Aforesaid a kind of breaker device that is used for the limit protection of steel rope is characterized in that said limit switch also comprises the micro-switch that is used to compress said link rod.
Aforesaid a kind of breaker device that is used for the limit protection of steel rope is characterized in that, also is installed with the bolt that is used to compress link rod at the free end of said link rod.
The beneficial effect of the utility model is: the rope guide of the breaker device that the utility model provides is that a nip drum is positioned over the suitable position of reel, and when steel rope was wrapped on the reel, nip drum can make steel rope free in and out just; When steel rope breaks away from drum rope groove, just touch nip drum, nip drum is ejected certain distance; Drive a micro-switch this moment, cut off the rising power supply, suspension hook one segment distance descends this moment; Again rise; Make steel rope reinstall grooving and twine, realize that steel rope twines unlikely disorder, improved work efficiency greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the scheme drawing that the utility model is used for steel-wire rope type electric block.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
With reference to shown in Figure 1; It comprises board 2; Limit switch 4 that on said board 2, is installed with rotating link rod 3, compresses each other with said link rod 3 and the spring 5 that is used to reset; The also affixed guiding latch 6 of the free end of said spring 5, said guiding latch 6 is put and is dissolved on the said link rod 3, around said board 2, also is installed with the spacing anti-collision body 7 that is used to compress said link rod 3; Said limit switch 4 also comprises the micro-switch 8 that is used to compress said link rod 3, also is installed with the bolt 9 that is used to compress link rod 3 at the free end of said link rod 3.
Continue with reference to shown in Figure 1, said spring 5 is installed on the board 2, and the reseting performance of spring 5 acts on the guiding latch 6, makes the link rod 3 of accommodating guiding latch 6 can recover normal condition as early as possible; On board 2, also be provided with spacing anti-collision body 7 in addition, the link rod 3 that is used to conflict prevents that micro-switch 8 from too oppressing, and when link rod 3 leaves micro-switch 8, makes limit switch 8 open, and cuts off the electricity supply, and has avoided the generation of safety misadventure.
With reference to shown in Figure 2, it comprises reel 11, is provided with nip drum 12 at the periphery of reel 11; Between nip drum 12 and reel 11, be provided with grooving, grooving is accommodated steel rope 10, makes nip drum 12 that steel rope 10 is freed in and out; When steel rope 10 breaks away from reel 11 groovings, just touch nip drum 12, nip drum 12 is ejected certain distance; Drive a micro-switch 8 this moment, cut off the rising power supply, suspension hook one segment distance descends this moment; Again rise, make steel rope 10 reinstall grooving and twine, realize that steel rope 10 twines unlikely disorder.
More than show and described groundwork, principal character and the advantage of the utility model.The technical personnel of the industry should be understood; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification sheets that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain by appending claims and equivalent circle thereof.
