Abstract
The utility model discloses a steel-wire chuck-proof and rope detaching-proof electric hoist case, relating to a crane accessory. The technical problem solved by the utility model is to design a steel-wire chuck-proof and rope detaching-proof electric hoist case, in which the steel wire can not detach the reel and be chucked on an output shaft of a reducer or on the front cover of a motor to cause accident. The technical proposal of the utility model is that the steel-wire chuck-proof and rope detaching-proof electric hoist case comprises a case, of which a protruding sleeve is arranged on the inner end surface of each of the two flanges; the diameter of the protruding sleeve hole is not less than the outer diameter of the reel; the distance between the inner end surfaces of the two protruding sleeves is bigger than the length of the reel; the distance between the inner corner angle of the protruding sleeve and the corner angle of the reel is less than the radius of the steel wire; and the distance between the inner end surfaces of the two protruding sleeves is bigger than the length of the reel. The utility model can be applied on a steel-wire electric hoist.
Description
Technical field:
The utility model relate to a kind of elevator machinery accessory, particularly a kind of steel-wire rope type electric block the anti-sticking rope, take off the shell of rope.
Background technology:
Existing steel-wire rope type electric block, the normal steel rope that takes place takes off rope, blocks the accident of restricting from its reel, its reason mainly is that the inside face of shell two end flanges is bigger apart from the distance at reel edge, steel rope often takes place when steel rope is wound into the termination of reel to come off or stuck on reducer shaft and motor front end cover, accidents caused from reel.
Summary of the invention:
The technical matters that the utility model Technology Need solves is a kind of steel-wire rope type electric block anti-sticking anticreep rope shell of design, and it is stuck to reducer output shaft or on the motor front end cover and accidents caused that steel rope can not break away from reel.The technical solution of the utility model is, steel-wire rope type electric block anti-sticking anticreep rope shell, comprise shell, it is characterized in that: on the inner end surface of two flanges of shell, respectively be provided with a protruding cover, the diameter of protruding trepanning is not less than the external diameter of reel, the length of the distance 〉=reel between the inner end surface of two protruding covers, the distance between the interior drift angle of protruding cover and the drift angle of reel is less than the radius of steel rope.Distance between the inner end surface of two protruding covers equals the length of reel.The utility model technology is owing to be provided with protruding cover on the inner end surface of flange, thereby has compared with the prior art and prevent that steel rope from being blocked or take off the advantage that the rope accident takes place.
Description of drawings:
Fig. 1 is a vertical section structure scheme drawing of the present utility model, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the partial enlarged drawing of Fig. 1.
The specific embodiment:
In conjunction with above accompanying drawing the utility model is described in detail, the reel of electric block, shell be normalisation all, under the condition of the outer cooperative dimensioning that does not change shell 3, about respectively be provided with a protruding cover 2 on the inner end surface of two flanges 1, the slightly larger in diameter of protruding trepanning is in the external diameter of reel 4, distance between the opposing end faces of two protruding covers equals the length of reel, also can be greater than the length of reel, but all should meet the following conditions, promptly after reel assembling in the enclosure, the gap L that the interior drift angle 5 of protruding cover and the drift angle of reel are 6 should be less than the radius (referring to Fig. 3) of steel rope.Owing to be provided with protruding cover on flange, the length of protruding cover has solved the problem of taking off rope and card rope with the gap between existing reel termination and the end face of flange (greater than the diameter of steel rope), does not also change the outer cooperative dimensioning of reel and shell.
Claims (2)
1, steel-wire rope type electric block anti-sticking anticreep rope shell, comprise shell, it is characterized in that: on the inner end surface of two flanges of shell, respectively be provided with a protruding cover, the diameter of protruding trepanning is not less than the external diameter of reel, the length of the distance 〉=reel between the inner end surface of two protruding covers, the distance between the interior drift angle of protruding cover and the drift angle of reel is less than the radius of steel rope.
2, steel-wire rope type electric block anti-sticking anticreep rope shell as claimed in claim 1, it is characterized in that: the distance between the inner end surface of two protruding covers equals the length of reel.
