Abstract
An anti-jamming shell of steel-wire rope type electric block comprises a shell, which is characterized in that: each inner end face of two supporting rings on the shell is arranged with a convex sleeve with the diameter not less than the diameter of the drum. The distance of two inner end faces of two convex sleeves is more than or equal to the length of the drum. The distance L between the convex sleeve and the drum is more than zero and less than the radius of the steel-wire rope.
Description
Technical field:
The utility model relates to a kind of elevator machinery accessory, particularly a kind of steel-wire rope type electric block anti-sticking rope shell.
Background technology:
Existing steel-wire rope type electric block, the normal accident that the wire line shoe rope takes place and take off rope, its reason mainly is that the inside face of shell two end flanges is bigger apart from the distance at reel edge, when oblique lift heavy thing phenomenon takes place, at this moment, if the gap will be caused and take off the rope accident greater than the diameter of rope, if the gap is less than the diameter of rope, and greater than the rope radius the time, though steel rope can not take off rope, can take place in the stuck gap between reel and flange of steel rope, cause the stuck accident of steel rope.
Summary of the invention:
The utility model technical issues that need to address are a kind of steel-wire rope type electric block anti-sticking rope shells of design, and steel rope can not be stuck and can not break away from reel to reducer output shaft or on the motor front end cover and accidents caused yet.The technical solution of the utility model is, steel-wire rope type electric block anti-sticking 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 protruding cover and the reel are L, the radius of 0＜L＜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 is stuck and takes 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,
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 is 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, being convenient to reel releases in housing, distance between the two protruding cover opposing end faces 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 in the protruding cover between the top of the top of drift angle 5 and reel drift angle 6 should be less than the radius (referring to Fig. 3) of steel rope.Owing on flange, be provided with protruding cover, the length of protruding cover gap excessive between reel termination and the end face of flange can be resolved (greater than the diameter of steel rope), make the radius of this gap less than rope, thereby this steel-wire rope type electric block shell can not cause the accident that steel rope is stuck and take off rope because of tiltedly drawing weight, this reel does not change the standard of reel and the outer cooperative dimensioning of shell simultaneously, has made things convenient for user's installation and maintenance.
Claims (2)
