Definitions
- the present invention relates to lifting or traction cables, in particular cables for elevators, that is to say the cables which support the elevator car and transmit to it the movement of the drive drum.
- the type of cable conventionally used for such applications is a mixed cable with eight strands of steel wires wound helically on a core of natural textile with hard fibers, such as sisal.
- a similar cable is also known, but whose core itself is mixed, namely consisting of metal strands and textile fibers for filling.
- the traction cables for elevators can also be cables with metallic strands on a metallic core, independent or not.
- cables are also used comprising natural fibers of the sisal type, or synthetic fibers (polypropylene), the role of which is to form a mattress inserted between the different layers. strands.
- the aim is thus to avoid or at least limit the friction of the wires or strands against each other, and the risks of indentation, in order to improve and maintain the flexibility of the cable, and to avoid breaks in the wires.
- the present invention aims to solve the problems mentioned above. It aims in particular to provide a lifting or traction cable which has, at equal weight, considerably increased breaking strength compared to known all-steel cables or mixed cables, allowing in particular, at equal mass, to increase the payload as well as the stroke height of the elevators, or, at equal load , to reduce the number of strands or the diameter of the cables used.
- the invention relates to a mixed cable comprising a plurality of strands stranded around a core of synthetic material, characterized in that the core is constituted by a core formed by a bundle of synthetic fibers. parallel extending in the longitudinal direction of the cable, and by a compact sheath of thermoplastic material enclosing said core and serving as a winding support for the strands.
- the invention also relates to a mixed strand comprising a plurality of outer wires stranded around a core of synthetic material, this strand being characterized in that the core consists of a core formed by a bundle of parallel synthetic fibers extending in the longitudinal direction of the strand, and by a sheath in thermoplastic material enclosing said core and serving as a winding support for the wires.
- the invention resides in its essential characteristics, in the presence of a composite synthetic core with two components arranged concentrically: a compact sheath but deformable by radial compression (a thermoplastic) which tightly surrounds a formed central core of a bundle of individual fibers, also made of synthetic material, substantially continuous along the length of the cable, and arranged so as to effectively participate in any tensile force exerted on the cable by a load.
- a composite synthetic core with two components arranged concentrically: a compact sheath but deformable by radial compression (a thermoplastic) which tightly surrounds a formed central core of a bundle of individual fibers, also made of synthetic material, substantially continuous along the length of the cable, and arranged so as to effectively participate in any tensile force exerted on the cable by a load.
- the synthetic material serves as padding, to ensure the maintenance of the strands or the wires relative to each other in the section of the cable, and thus to avoid for example friction of the wires. metallic one on the other or even in
- the section and the number of fibers of the cable or strand according to the invention are determined so that the core forms with the metal wires or strands an assembly such as the deformations under load, mainly in elongation, are substantially equivalent for the core of synthetic fibers and for the strands or external metal wires, despite the differences in mechanical characteristics of these materials.
- the sheath surrounding the fibers is made of a deformable but not very compressible material, so that this material creeps during the manufacture of the cable or the strand until filling the free spaces between the core and the strands or wires of the layer directly surrounding the soul.
- the sheath is used in particular to hold the fibers parallel together, ensuring the compactness of the core. It will be noted that the transmission of forces between the strands or external wires and the core is all the better ensured by friction between the sheath and the said strands or external wires as these penetrate into the material of the sheath, since this increases the contact surface. Furthermore, the sheath constitutes an intermediate layer between the strands or external wires and the fibers of the core, which avoids or at least limits the shearing effect of the fibers, which extend in the axial direction, through the external wires. , or the wires of the outer strands, which are transverse to said axial direction.
- the fibers are preferably made of polyethylene or aramid, and the sheath is for example made of extruded polyamide.
- the outer strands of the cable according to the invention may be entirely metallic, that is to say entirely made up of metallic wires, or mixed, and in particular made up of mixed strands themselves conforming to the invention.
- FIG. 1 is a section of a mixed strand according to the invention
- FIG. 2 is a section of a cable according to the invention according to a first embodiment
- FIG. 3 is a section of a cable according to the invention according to a second embodiment.
- the strand represented in section in FIG. 1, comprises a composite synthetic core 4 with a concentric structure: a central core 1 formed by a bundle of free and parallel fibers, the cohesion of which is ensured by a monolithic sheath 3 which corsets the bundle.
- This core is surrounded by a layer of steel wire 2 (here ten in number) wound in a spiral on the sheath 3, and which presses it around the core 1 thereby giving it their imprints, as seen on the drawing.
- the fibers 1 constituting the core are for example fibers of polyethylene, aramid, kevlar®, Twaron®, etc.
- the sheath 3 is made of a thermoplastic material, for example a polyamide, having good adhesion properties with the fibers of the core.
- the cable shown in section in Figure 2 is composed of a core 5 of synthetic fibers similar to the core 4 described above and surrounded by twelve strands of seventeen steel wires. Between the core 11 and the outer layer of strands 12, an intermediate layer of thermoplastic material is interposed, constituting a compact sheath 13 which is pressed around the core by the strands 12. As can be seen in the drawing, the wires strands, located towards the inside of the cable, are embedded in the thermoplastic material of the sheath 13, thus providing a large contact surface and therefore a strong adhesion.
- the latter is further reinforced by the centripetal radial compression effect exerted by the strands on the sheath when tension is exerted on the cable.
- the constituent materials of the core 5, the core 11 and the sheath 13, are of the same type as those indicated for the strand of FIG. 1.
- FIG. 3 shows yet another cable, comprising a core of synthetic fibers 5 provided with a central bundle 11 of synthetic fibers and a sheath of thermoplastic material 13.
- the eight strands 10 are not entirely made of steel, but are in fact strands conforming to that shown in FIG. 1.
- the breaking load of a conventional cable, even a mixed cable is essentially dependent on the metal section which is the sum of the sections of all the wires making up the cable. It practically does not depend on the non-metallic inserts existing in mixed cables, and in particular on synthetic fibers which, having mainly only a function of filling voids between wires or strands, do not take up any part of the load.
- the weight of the cables is primarily due to the weight of the steel wires making it up.
- the breaking load / weight ratio of steel cables is substantially constant, mainly depending only on the construction of the cable and not on its diameter.
- the comparative table below indicates the R / P ratio of the breaking load R, by weight per meter P, for two types of cables, 8 x 19 and 12 x 17, in a common embodiment (col. 2) and made according to the invention (col. 3) respectively.
- the load useful can be increased, or vice versa, for the same load, the weight and the diameter of the cables can be reduced, making it possible to reduce the dimensions of the machines or frames of lifts or similar devices. Also, the service life of the cables according to the invention is increased compared to all-steel cables.
- the implementation of the cables according to the invention does not require any modification of the existing installations: the anchors and the cable terminations are identical to the conventional applications of steel cables; the interface between the drums of the machinery and the cable is always a steel contact on the drum material, which does not modify the conditions of a transmission of movement by adhesion; the removal and replacement criteria are similar, based on the reduction in diameter and the number of broken steel wires; and the cables of the invention are no more susceptible to acts of vandalism than all-steel cables.
- the invention is not limited to the embodiments which have been described above solely by way of example.
- the number of wires of each strand, and the number of strands of the cable can obviously be modified.
- the use of these cables is not limited to their application as elevator cables, and they can also be used as hoisting cables, lines, for mountain or maritime applications, etc. .
