For example be appreciated that by Fig. 5, the opening 78 in cable 46 process cable positioners 76, any broken ends of scattering can not be passed opening 78.This makes cable be out of shape and has interrupted band rope manufacture process.
In an example, apply the part of process as sheath, check the state of cable so that the problem that the broken ends that prevents to scatter causes.Being arranged on the appropriate position in this shaped device 70 to above-mentioned another similar detector arranges so that guarantee wire rod suitable in band rope manufacture process.
Device for molding 70 is included in the opening 80 on the outlet side 82 of mould housing 72.Opening 80 is preferably shaped to outer shape and the surface of being convenient to control band rope assembly 20.
In the example depicted in fig. 6, the opening 80 of device for molding 70 has non-linear configuration along the part on the formation deflector roll contact zones rope surface of this opening.This non-linear configuration provides the different-thickness of band rope assembly along width.Be appreciated that by accompanying drawing being with the rope assembly to compare with the part that cable is not set of band rope assembly corresponding to the part of cable 46 positions has the thickness that reduces.
The non-linear configuration of the variation on surface 86 and 88 can be configured to accommodate in the variation along the amount of contraction of being with Suo Kuandu that occurs in band rope surface treatment and solidification process.Should be appreciated that the cross section of amount of contraction corresponding to urethane jacket material.In the zone with cable 46, owing to there is cable materials, cable materials is a steel in some instances, so amount of contraction is less.The part that does not have cable of band rope assembly has temporary transient big thickness, and this is because have bigger amount of contraction in these positions of band rope assembly.
The varied in thickness that provides along element width helps to realize final acquisition: flat surface 86 and 88 and on the surface parallel alignment between 86 and 88.Structure type shown in Figure 6 is unique for the scheme of making band rope assembly.In the process of prior art, the mold wheel that is comprised applies the part of station as sheath.This mold wheel is compacted into flat structure with sheath material in operation, and it is as the part of initial cooling procedure.Therefore, the technical scheme that the thickness of non-linear configuration changes as the part of a kind of exemplary form of implementation of the present invention, has solved the problem that occurs the amount of contraction variation in solidification process with unique mode.
In an example, in the thickness of the sheath of making by the opening 80 of device for molding shown in Figure 6, have roughly.05-.10 the variation of millimeter.The overall dimension of specific band rope assembly, the size of cable and selected sheath material will stipulate that the required specific thicknesses of particular case changes.In conjunction with this specification, those of ordinary skill in the art can select suitable size so that satisfy the needs of its particular case.
By the present invention, the band rope or the main body of rope or the length of cable main body can increase significantly.If when wire rod ruptures, cut off the cross section of strand or cable simply, then cause undesirable material discarded, and unavailable strand of many length or cable for most lifts are installed, occur.By using above-mentioned example technique, provide the obvious increase of the length of cable and band rope main body.In an example, the order of magnitude without any the band Suo Changdu that cuts-be welded to connect in being subjected to draw piece is 13km.Therefore, this example technique makes and is subjected to the not only more saving, more effective of draw piece manufacture process.
This exemplary embodiment can comprise one or more broken wires in a certain position.Form each strand and 7 strands form in the example of each cable at 7 wire rods, about 2% of the resistance to tension of a broken wires representative loss continuous wire.This minute differences can obviously not influence intensity, and this is not have broken wires because many wire rods are some or the overwhelming majority in undamaged and a plurality of cables at all.
By this exemplary technology, handle broken wires by this way, that is, increase lift band rope manufacturing efficient relevant with rope and saving property and make and are installed.
Above description only is exemplary, rather than restrictive.Under the situation that breaks away from the spirit and scope of the invention, those of ordinary skill in the art can make various modification and change.Protection scope of the present invention is only limited by following claim.
