Definitions

  • the invention relates to a rope as a suspension element for lifts, which is connected to a cabin or load suspension means, the rope consisting of synthetic fibers.
  • steel cables are used in elevator construction, which are connected to the cabins or the load handling devices and counterweights, in the simplest case 1: 1.
  • the use of steel cables has some disadvantages. Due to the high weight of the steel cable, the lifting height of an elevator system is limited.
  • the coefficient of friction between the metal traction sheave and the steel cable is so low that the coefficient of friction must be increased by various measures such as special groove shapes or special groove feedings in the traction sheave or by increasing the wrap angle.
  • the steel cable between the drive and the elevator car acts as a sound bridge, which means a reduction in driving comfort. In order to reduce these undesirable effects, complex constructive measures are required.
  • steel ropes endure a lower number of bending cycles than synthetic fiber ropes, are exposed to corrosion and require regular maintenance.
  • a steel cable is also used as a suspension element, which has the disadvantages mentioned above. Furthermore, due to the small length of the running surface of the rope pulley in relation to the length of the steel rope, the elastic insert is heavily worn and therefore has to be replaced often, which entails high maintenance costs.
  • the invention has for its object to propose a rope as a suspension for lifts of the type mentioned, which does not have the aforementioned disadvantages and by means of which the driving comfort is increased.
  • the measures listed in the subclaims permit advantageous developments and improvements of the synthetic fiber rope specified in claim 1.
  • the Sheathing the synthetic fiber rope creates higher friction values on the traction sheave, so that the loop can be kept smaller.
  • the coefficient of friction can be influenced by different properties of the casing surface. This enables the traction sheaves to be standardized, since different groove shapes are no longer required.
  • the traction sheave diameter must be 40 times the rope diameter.
  • the traction sheave diameter can be chosen significantly smaller due to their nature. Compared to steel ropes, synthetic fiber ropes, with the same diameter ratios, allow a significantly larger number of bending changes.
  • a sheathing 2 surrounds an outermost strand layer 3.
  • the sheathing 2 made of plastic, preferably polyurethane, increases the coefficient of friction of the rope 1 on the traction sheave.
  • the outermost strand layer 3 must have such high binding forces to the sheathing 2 that it does not shift due to the shear forces occurring when the rope 1 is loaded or bulges form. These binding forces are achieved by spraying (extruding) the plastic sheath 2 so that all the spaces between the strands 4 are filled and a large holding surface is formed.
  • the strands 4 are twisted or beaten from individual aramid fibers 5.
  • each individual strand 4 is treated with an impregnating agent, for example a polyurethane solution.
  • an impregnating agent for example a polyurethane solution.
  • the ability of the rope 1 to change bends depends on the proportion of polyurethane in each strand 4. The higher the proportion of polyurethane, the higher the bending performance. However, the load-bearing capacity and the modulus of elasticity of the synthetic fiber rope 1 decrease with increasing polyurethane content.
  • the polyurethane content for impregnating the strands 4 can, for example, between ten and sixty percent, depending on the desired bending alternating power lie.
  • the individual strands 4 can expediently also be protected by a braided sheath made of polyester fibers.
  • a friction-reducing intermediate jacket 7 is therefore attached between the outermost strand layer 3 and the inner strand layer 6.
  • the same friction-reducing effect can be achieved by treating silicone of the strands 4 underneath.
  • the wear is kept low in the outermost strand layer 3 and in inner strand layers 6, which perform the most relative movements when the rope bends on the traction sheave.
  • Another means of preventing frictional wear on the strands 4 could be an elastic filling compound which connects the strands 4 to one another without reducing the flexibility of the rope 1 too much.
  • elevator ropes Unlike pure tether ropes, elevator ropes have to be turned or braided very compactly and tightly so that they do not deform on the traction sheave or start to turn due to the intrinsic twist or deflection.
  • the gaps and voids between the individual layers of the strands 4 are therefore filled by means of filling strands 9, which can act as a support against other strands 4, in order to obtain an almost circular strand layer 6 and to increase the degree of filling.
  • These fillets 9 are made of plastic, e.g. made of polyamide.
  • the aramid fibers 4 consisting of highly oriented molecular chains have a high tensile strength. In contrast to steel, the aramid fiber 5 has a rather low transverse strength due to its atomic structure.
  • the strands 4, twisted or beaten from aramid fibers 5, including the filler strands 9, are tied in layers to the left or right in a layer around a core 10.
  • the friction-reducing intermediate sheath 7 is attached between an inner and the outermost strand layer 3.
  • the outermost strand layer 3 is covered by the sheath 2.
  • the surface 11 of the casing 2 can be structured.
  • the task of the sheathing 2 is to ensure the desired coefficient of friction with the traction sheave and to protect the strands 4 from mechanical and chemical damage and UV rays.
  • the load is borne exclusively by the strands 4.
  • the rope 1 constructed from aramid fibers 5 has a substantially higher load-bearing capacity and only one fifth to one sixth of the specific weight compared to a steel rope with the same cross section. For the same load-bearing capacity, the diameter of a synthetic fiber rope 1 can therefore be reduced compared to a conventional steel rope. By using the above materials, the rope 1 is completely protected against corrosion. Maintenance like steel cables, e.g. to grease the ropes is no longer necessary.
  • Another embodiment of the synthetic fiber rope 1 consists in the different design of the sheathing 2.
  • each individual strand 4 is provided with a separate sheath which is closed all round, preferably made of polyurethane or polyamide.
  • a sheath 2 surrounding the entire outermost strand layer 3 each individual strand 4 is provided with a separate sheath which is closed all round, preferably made of polyurethane or polyamide.
  • the further construction of the synthetic fiber rope 1 remains identical to the embodiment described in FIGS. 1 and 2.
  • FIG. 3 shows a schematic representation of an elevator installation.
  • a car 13 guided in an elevator shaft 12 is driven by a drive motor 14 with a traction sheave 15 via the synthetic fiber rope 1 according to the invention.
  • a counterweight 16 At the other end of the rope 1 hangs a counterweight 16 as a compensating element.
  • the coefficient of friction between rope 1 and traction sheave 15 is now designed such that further promotion of cabin 13 is prevented when counterweight 16 is placed on a buffer 17.
  • the cable 1 is fastened to the cabin 13 and to the counterweight 16 via cable end connections 18.
  • the coefficient of friction between rope 1 and a deflection sheave should be as small as possible in order to keep the friction losses low.
  • the deflection sheave does not transmit any drive torque to the rope 1.
  • the sheathing 2 can also be made of polyamide instead of polyurethane to reduce the coefficient of friction.
  • FIG. 4 shows a schematic representation of an elevator installation with a 2: 1 sheathing.
  • rope end connections 18 for the synthetic fiber rope 1 are not attached to the cabin 13 and to the counterweight 16, but rather in each case to the upper shaft end 19.
  • the shape of a groove 20 of the traction sheave 15 coupled to the drive motor 14 of the elevator is preferably semicircular for optimum fitting of the rope 1. Since the rope 1 deforms somewhat under load on the support surface, an oval groove shape can also be selected. These simple groove shapes can be used because the plastic jacket 2 generates a sufficiently high coefficient of friction. At the same time, the wrap angle of the rope 1 on the traction sheave 15 can be reduced due to the high friction values.
  • the groove shape of the traction sheave 15 can be designed identically for lifts of different loads, since the coefficient of friction is determined by the surface structure 11 and the material of the casing 2.
  • the dimensions of the traction sheave 15 can be reduced due to the smaller rope diameter of the synthetic fiber rope 1 and the associated smaller possible traction sheave diameter.
  • a smaller traction sheave diameter leads to a smaller drive torque and thus to a smaller motor size.
  • the production and warehousing of the traction sheaves 15 are also considerably simplified and cheaper.
  • the large contact surface of the rope 1 in the groove 20 also results in smaller surface pressures, which considerably extends the life of the rope 1 and traction sheave 15.
  • the rope 1 made of aramid fibers 5 also does not allow transmission of the frequencies emanating from the traction sheave 15. An excitation of the cabin 13 via the cable 1 which reduces the driving comfort is thus omitted.
