Abstract
The invention provides a kind of steel rope that can increase the traction sheave cornerite is solved steel rope to traction sheave skid easily the two-wheel towing machine of using for elevator of problem and the winding method of steel rope thereof.Include two with turn to, same rotating speed, isostructural traction sheave, is processed with on the traction sheave for every steel rope and wears grooving, and the quantity of grooving is no less than two around usefulness.The winding method of steel rope is: after steel rope is successively walked around article one grooving of two traction sheaves, change the second grooving of previous traction sheave over to by article one grooving of a back traction sheave, and then lay out by the second grooving that this grooving forwards a back traction sheave to.After adopting said structure, cornerite is bigger, and the possibility of skidding is few more, and traction sheave and steel rope slide relative reduce, and the wearing and tearing of phase mutual friction are just few more, and will prolong the service life of steel rope and traction sheave.The adverse effect that causes just can be reduced to minimum level because of skidding.
Description
Technical field:
The present invention relates to a kind of building operation and use the elevator technology field, refer in particular to a kind of towing machine of elevator of rope hoisting and the winding method of steel rope.
Background technology:
As guide rail bracket, include the building hoist of rope hoisting cage with steel headframe, at home, particularly use extensively existing history more than 50 years in Guangdong and Hong Kong and Macao.At first use the elevator combination of the theory structure of the single-wheel towing machine (mine friction sheave winder) of indoor elevator and mining hoist use and steel headframe rope hoisting in Guangdong, and effect is better.But only be used for loading, fail to be used for manned.The manned use of indoor elevator has surpassed 150 years history, and mining hoist is also historical long-range with the manned loading of single-wheel towing machine (friction sheave winder), and the single-wheel towing machine is equipped with anti-dropping safety devices such as corresponding anti-break rope, and is reliable and practical.
But use experience for many years shows, when single-wheel towing machine steel rope was worn behind traction sheave parallel laying out, its cornerite was 180 °, and the friction face of steel rope and traction sheave grooving has only circumference half.Add the open-air usage condition in building site and more coarse towing machine process for machining and manufacturing, easily cause the single-wheel towing machine to skid easily, cause steel rope abrasion more serious because of skidding than winch, rope service-life is short, easily broken rope, brings safe addiction to suffer from: the control of elevator craning cage flat bed also is difficult to accurately because of skidding.The corresponding anti-dropping safety device problem of solution is not also arranged in addition, thereby also do not have in Guangdong so far and can use for the building hoist product-feed building site of manned cargo-carrying steel headframe rope hoisting.
Summary of the invention:
The invention provides a kind of steel rope that can increase the traction sheave cornerite is solved steel rope to traction sheave skid easily the two-wheel towing machine of using for elevator of problem and the winding method of steel rope thereof.
For achieving the above object, technical scheme provided by the invention is:
A kind of two-wheel towing machine of using for elevator, its characteristics are: include two with turn to, same rotating speed, isostructural traction sheave, is processed with on the traction sheave for every steel rope and wears grooving, and the quantity of grooving is no less than two around usefulness.
The winding method of the two-wheel towing machine steel rope that a kind of confession elevator is used, this method is: after steel rope is successively walked around article one grooving of two traction sheaves, change the second grooving of previous traction sheave over to by article one grooving of a back traction sheave, and then lay out by the second grooving that this grooving forwards a back traction sheave to.Whenever walk around a pair of grooving, when the steel rope two ends became parallel laying out, its cornerite was 270 °, and when walking around second pair of grooving again, the cornerite of steel rope is 2 * 270 °=540 °.Each root steel rope can be around three pairs, four pairs if necessary ... grooving.It is 3 * 270 °, 4 * 270 ° that corresponding cornerite increases ... etc.
Electrical motor of the present invention drives two same structure sizes by reduction gear apparatus, during traction sheave that same rotational speed turns to, the positive pressure that is caused on traction sheave by lineoutofservice signal pull and the friction force (traction) that produces makes steel rope rotate with traction sheave is realized the lifting of cage.Cornerite is big more, and the possibility of skidding is few more, and traction sheave and steel rope slide relative reduce, and the wearing and tearing of phase mutual friction are just few more, and will prolong the service life of steel rope and traction sheave.The adverse effect that causes just can be reduced to minimum level because of skidding.
Description of drawings
The block diagram of Fig. 1 embodiment of the invention towing machine;
Fig. 2 is the front view of embodiment of the invention towing machine;
Fig. 3 is the birds-eye view of towing machine of the present invention;
Fig. 4 is the winding method scheme drawing of two-wheel towing machine steel rope.
The specific embodiment
See that Fig. 1～shown in Figure 3, present embodiment include the gear cluster that 1,2, three gears of two traction sheaves 3,4,5 are formed, drop-gear box 6, drg 7, motor 8.Two traction sheaves 1,2 are connected with gear 3,5 by transmission shaft respectively, and gear 4 is connected with the output shaft of drop-gear box 6, and the input shaft of drop-gear box 6 is connected with the coupler of drg 7, and motor 8 is connected with the coupler of drg 7.In order to increase safety factor, this example uses two steel ropes, therefore, each traction sheave forms two groups of groovings totally four groovings, that is to say two grooving 1a, 1b on the traction sheave 1 and two grooving 2a, 2b on the traction sheave 2 for a steel wire penetrating, other one group of grooving is for another steel wire penetrating.During work, at first electrical motor 8 startings, drg 7 is opened simultaneously, by the deceleration of drop-gear box 6, forces 1,2 work of two traction sheaves through the gear cluster transmission again.
In addition, two traction sheaves also can only need to guarantee the traction sheave structure by driving device independent drive separately, turn to, rotating speed is identical, and driving device can be mechanical drive or hydrostatic drive etc.
Below in conjunction with accompanying drawing 4, winding to a steel rope is elaborated, and (two or more winding is identical with one, just independently walk around respectively and get final product), at first the end with steel rope 11 is connected with the cage 13 of building hoist by guide wheel group 12, the other end of steel rope 11 is walked around the bottom of article one grooving 14a of first traction sheave 14 through 90 ° of cornerites, after this end is walked around the bottom of article one grooving 15a of second traction sheave 15 through 180 ° of cornerites then, enter the top of the second grooving 14b of first traction sheave 14 again, lay out through 90 ° of cornerites around the second grooving 15b that goes into second traction sheave 15 by its bottom through 180 ° of cornerites,, realize the dipping and heaving of cage 13 after guide wheel group connects counterweight.When the steel rope two ends wear around after, not parallel output (two ends near or two ends separately) time, the size of cornerite than 540 ° or more greatly or less, does not influence practical effect.In sum, every steel rope is through after grooving lays out more than two pairs on the two-wheel towing machine, and its cornerite can be the cornerite of used single-wheel towing machine more than three times, obviously reduces and skids.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so the equivalence that all shapes according to the present invention, structure and principle are done changes, all should be covered by in protection scope of the present invention.
