Abstract
The utility model discloses an anti-extrusion slot device of a travelling crane steel wire rope. The anti-extrusion slot device comprises a mandrel, wherein a fixed pulley sheet is sleeved outside the mandrel. The anti-extrusion slot device of the travelling crane steel wire rope is characterized in that four small out-of-slot proof pulleys on the same surface with other small out-of-slot proof pulleys are arranged at the outer side of the circumstance on which the fixed pulley sheet is in contact with the steel wire rope; the diameter of the section of a rope wrapping groove of the fixed pulley sheet is more than the thickness of the small out-of-slot proof pulley; the front ends of the small out-of-slot proof pulleys extend into the rope wrapping groove of the fixed pulley sheet; and a basically sealed space is formed by a pulley sheet groove in a fixed pulley block and a groove of the small out-of-slot proof pulleys. Compared with the prior art, the anti-extrusion slot device has the advantage of good rope jumping prevention effect.
Description
Technical field
The utility model relates to elevator machinery driving technical field, and especially the driving steel wire rope safe in operation prevents out slot device.
Background technology
At present, large and medium-sized enterprise more use hoisting crane, especially smelter, because the production material amount of having bad luck of smelter is bigger, crane trolley uses frequent.
In the process of moving operation,, influence normal operation, also bring safety hazard to production because a variety of causes very easily causes the steel rope groove of upspringing out.The original design scheme drawing is like Fig. 1, shown in 2: mainly be made up of protective cover 1, fixed pulley sheet 2, axle 3 and dolly car body 4; Axle 3 is fixed on the dolly car body 4 with protective cover 1; Fixed pulley sheet 2 is installed on the axle 3; Steel rope is wrapped on the fixed pulley sheet 2, prevents the steel rope groove of upspringing out at work by fixed pulley sheet 2 and protective cover 1.Through there is defective in the original structure of field tracking analysis.Mainly be between fixed pulley sheet and protective cover, to have the gap, can not prevent effectively that steel rope from going out groove.
Summary of the invention
For overcoming the deficiency of prior art, the utility model provides a kind of driving steel wire rope anti-extrusion slot device,
It can overcome above shortcoming, can prevent effectively that steel rope from going out groove.
For achieving the above object, the technical scheme that the utility model adopted is following:
A kind of driving steel wire rope anti-extrusion slot device comprises axle, and axle is arranged with the fixed pulley sheet outward, and the periphery that said fixed pulley sheet contacts with steel rope is provided with one at least and prevents the groove small sheave, said fixed pulley sheet with prevent groove small sheave coplane; The fixed pulley sheet with prevent the diameter of groove small sheave two circular arc corresponding positions distance less than rope.
Above-mentioned driving steel wire rope anti-extrusion slot device is describedly prevented the groove small sheave and is provided with two at least along said contact circumference.
Above-mentioned driving steel wire rope anti-extrusion slot device, described prevent the groove small sheave along the contact circumference be provided with four.
Above-mentioned driving steel wire rope anti-extrusion slot device, said upper and lower two small sheaves of preventing in the groove small sheave lay respectively at the place, upper and lower point of contact of steel rope and fixed pulley sheet.
Above-mentioned driving steel wire rope anti-extrusion slot device, said fixed pulley sheet wiring groove diameter of section groove small sheave thickness greater than preventing, prevents groove small sheave front end and stretches into pulley sheet wiring groove.
The beneficial effect of the utility model shows:
The utility model on the excircle wiring groove of fixed pulley sheet with it correspondence be provided with and prevent the groove small sheave, the both sides of steel rope are retrained by two pulley circumference, have avoided steel rope to go out the phenomenon of groove.
Steel rope is skipped rope and gone out groove generally is to begin in the position, point of contact of steel rope entering race; Originally prevent the groove small sheave and comprise two at least; And wherein two upper and lower ends get the position, upper and lower point of contact that two small sheaves lay respectively at steel rope and fixed pulley sheet; Can just begin to prevent that steel rope from beating and go out groove from rope inlet, have and prevent advantage such as groove is effective.
The utility model is provided with four along steel rope with contacting of fixed pulley sheet and prevents the groove small sheave outside the circumferencial direction, increase the obligatory point of steel rope, and along with increasing of obligatory point, anti-rope stretching effect is good more.
With preventing in the wiring groove that groove small sheave front end stretches into the fixed pulley sheet, there is not the space between the two basically, further reduced beating of steel rope, guarantee that steel rope can not go out groove.

The specific embodiment
Come the invention is described in detail with the specific embodiment below:
Like Fig. 3, shown in 4, a kind of driving steel wire rope anti-extrusion slot device comprises dolly car body 4, is fixed with axle 3 on the dolly car body 4, is arranged with two fixed pulley sheets 2 side by side outside the axle 3, and steel rope is wrapped on this fixed pulley sheet 2.
Circular arc that each steel rope contacts with fixed pulley sheet 2 outside is provided with four along its circumference and prevents groove small sheave 5, and these four small sheaves of preventing the upper/lower terminal of groove small sheave lay respectively at the position, upper and lower point of contact of steel rope and fixed pulley sheet 2.
Describedly prevent groove small sheave 5 and be set in and prevent in the groove small sheave rotating shaft 7, prevent that the both sides that groove small sheave rotating shaft 7 are fixed on the dolly car body 4 through fixed block 6.
Said fixed pulley sheet 2 wiring groove diameter of sections are prevented groove small sheave 5 front ends and are stretched into part in the pulley sheet wiring groove greater than the thickness of preventing groove small sheave 5.
This shows; Groove small sheave 5 for single preventing; The basic confined space that forms by the race of preventing groove small sheave 5 and fixed pulley sheet 2; Steel rope can shuttle in this space but can not to around motion, evenly arrange four at the same lower sheave group pulley sheet first half and prevent the groove small sheave, effectively prevent the steel rope groove of upspringing out in the course of the work.
