Definitions

  • the invention relates to a device for suspending a car or a counterweight in an elevator installation and method for assembling and maintaining suspension means according to the preamble of the independent claims.
  • Such an elevator system is shown in DE2333120, in which a car and a counterweight are suspended by means of steel belt hangers.
  • Several pulleys are combined to form a pulley unit, which is connected to the car or to the counterweight.
  • the individual pulleys are arranged on a common axis, so that the individual pulleys can rotate differently.
  • the pulley units must be matched to the number of steel straps used and assembled accordingly. An alignment of the pulley unit on the take-off direction of the bands can be done only as a whole and an individual length compensation of the bands of uneven load distribution, aging and wear or inaccurate assembly is not possible with this pulley unit.
  • Object of the present invention is now to propose a device which overcomes the aforementioned disadvantages.
  • the invention relates to a device for suspending a car or a counterweight in an elevator installation and method for mounting and maintaining suspension means, wherein the car or the counterweight hangs on carrying straps and the straps are connected by means of a plurality of pulleys to the car or counterweight ,
  • the device for suspending a car or a counterweight is designed in such a way that each deflecting roller is installed in a separate deflecting roller unit, each deflecting roller unit provides space for each individual carrying belt and each carrying belt is connected to the own deflecting roller unit with the car or with the counterweight ,
  • the advantage of this invention is the fact that each strap is assigned its own deflection roller unit.
  • the provision of the pulley unit for a particular job is thereby easily possible because the number of Umlenkrollenizien depends directly on the number of straps.
  • the device is suitable for use in the modernization of existing plants. Modernization consists of partially or completely replacing parts of an existing elevator installation. A typical modernization approach is to replace an old drive system.
  • a new drive system works preferably with suspended suspension and with strap.
  • the drive system can be operated with low torques and correspondingly low motor current, which enables the use of cost-effective assemblies.
  • the inventive device for suspending cabin or counterweight is best suited for this purpose because it has small dimensions, and is ideally connected to existing cabins or counterweights. Another advantage results from the direct usability of the deflection roller unit for mounting the support belt in an elevator installation. This simplifies the assembly process.
  • the pulley unit is individually adjustable in an advantageous embodiment. It can therefore be used to compensate for change in length of the strap.
  • the use of a tension bolt for connecting the pulley unit to the car, or to the counterweight allows each individual pulley unit to adjust to a required take-off direction of the support belt.
  • the withdrawal direction is understood to mean the direction which corresponds to the resulting force line, which results from the force sum of the support belt running up and down on the deflection roller unit.
  • Suspension means 6 are fastened here in the region of the shaft head 8 or directly to a drive unit 4 by means of suspension end fastening 9.
  • the support means 6 extends in a first section to a suspension 7 of the car, which is arranged on the car 2 and is guided in a second section from the car 2 to a drive or deflection disc of the drive unit 4.
  • a third section of the suspension element leads further from the drive unit 4 to a suspension 7 of the counterweight 3 arranged at the counterweight 3 and from the counterweight 3 to a counterweight-side suspension element end fastening 9.
  • the suspension element 6 is formed by a carrying strap 6.
  • the cross section of the support belt 6 is flat, wherein the traction serving surface may be smooth or shaped.
  • at least two carrying straps 6 carry the car 2 and the counterweight 3.
  • the carrying straps 6 are arranged next to one another.
  • each suspension element 6 is connected to the car 2 or to the counterweight 3 by means of its own deflection roller unit 10.
  • Direct neighborhood means that no other parts are arranged between the carrying straps 6 than those which serve to guide, hold or fix the carrying means 6, including the necessary safety distances.
  • the advantage of this solution is that it is easily possible to provide the deflection roller unit 10 for a specific application.
  • the number of pulley units 10. 1 , 10. 2 , 10. 3 to be delivered depends on the number of support belts 6 provided.
  • a job-specific pre-assembly of the pulley assemblies 10 is dispensed with. Furthermore, the individual deflection roller units 10 are individually rotatable and / or adjustable about an axis to a withdrawal direction of the respective support belt The distance of the deflection roller units 10 to the car 2, or to the counterweight 3 is adjustable, for example by threaded rods 20.
  • the individual deflection roller units 10 can be used to compensate for changes in length of the support strap 6. Length changes may occur during installation, for example, due to different support belt lengths, or they occur during operation, for example, due to unequal loading of the support strap 6, on.
  • the deflecting roller unit according to the invention can also be used without limitation for elevator systems with a split carrying belt arrangement.
  • the deflection roller unit 10 includes a deflection roller 11.
  • the deflection roller 11 is tuned to the width BT of the support belt.
  • the guide pulley unit 10 shown thus offers space for exactly one carrying strap 6. This allows an optimal use of the space as no unnecessary space is lost.
  • the guide roller 11 is mounted on an axle 12, advantageously by means of roller bearings 13, and the axle 12 is connected to a U-carrier 14, which holds the guide roller 11 laterally.
  • the axis 12 is, for example, provided on one side with a rotation 15 and caulked on the other side with the U-carrier 14.
  • the caulking is done by the axle 12 is provided with a shoulder and flange 16, which is widened to the U-carrier 14.
  • This embodiment is particularly space-saving and therefore allows small distances between adjacent pulley units 10. 1 , 10. 2
  • the support belt 6 comprises the deflection roller 11 usually with a peripheral angle of approximately 180 °.
  • a spacer 17 is arranged in the region of the deflection roller 11, which the carrying strap 6 does not comprise.
  • the spacer 17 may be made in one or more pieces. The spacer 17 determines the distance between the U-beam 14 formed by the U-leg on the side of the U-beam 14 which is open with respect to the U-shape and prevents it from falling objects into the inlet zone of the support belt. 6
  • the U-beam 14 forms at its, the spacer 17 opposite end of a semicircular arc.
  • This sheet forms the receptacle for a cylinder 18, which has a transverse bore 19.
  • a draw bolt 20 is inserted through the transverse bore 19 and is provided at its, the guide roller 11 facing the end with a nut 21, preferably a castle nut, and Sich ceremoniesssplint 22.
  • the tension bolt 20 establishes the connection of the deflection roller unit 10 with the car 2 or the counterweight 3.
  • the deflection roller unit 10 is adjustable about an axis defined by the tension bolt AV.
  • the arranged in the U-carrier 14 cylinder 18 also allows adjustment of the Umlenkrolleniser 10 about the axis of the cylinder 18th
  • the cylinder 18 is secured by means of a locking plate 23 against lateral slipping.
  • the securing plate 23 prevents damage to the deflection roller 11 by the tension bolt 20.
  • the design shown requires little space, is inexpensive to produce and it is adjustable according to a withdrawal direction of the strap 6.
  • the deflection roller unit 10 is designed such that the claimed by the deflection roller unit 10 width BU less than 1.7 times the width BT of the support belt 6 corresponds.
  • the example shown provides space for a strap 6 of about 30mm width BT.
  • the associated pulley unit 10 requires a width BU of about 43mm.
  • a distance of adjacent pulley units 10 can be set at about 48mm.
  • Existing elevator systems with suspension cables often have a suspension cable spacing of approximately 48 mm. The inventive design can thus for the modernization existing elevator systems are used excellently.
  • Existing connection hole patterns of cabin and counterweight can be taken over. This is inexpensive because the modernization interface is placed in an easily definable location.
  • the tension bolt 20 is secured to the end of the deflection roller 11 with a securing split 22, preferably a Federsplint. This allows easy assembly and disassembly of the pulley unit 10 in case of need.
  • a fixed attachment may be a screw head, which transmits the carrying capacity of the strap 6 on the car 2 or the counterweight 3. This attachment is advantageous when there is no room for more adjustable fixings.
  • An adjustable attachment is as shown in Figure 3, a threaded stud 20, on which a threaded nut 21 is arranged with a corresponding lock and Sich ceremoniesssplint, which transmits the carrying capacity of the strap 6 on the car or the counterweight.
  • a compensation of elongation of a support belt 6 takes place in that the support belt 6 is tensioned or relaxed by means of the tie rod 20 or by adjusting the threaded nut 21 on the tension bolt 20. This is advantageous because a large elongation of the support belt 6 can be compensated by this setting, as a Length change in the tension bolt 20 corresponds to a double change in length of the suspension element 6. An adjustment of the tension of the support belt 6 by means of the tension bolt 20 is thus very space-saving.
  • Vorteihaft type at least one carrying strap end fastening 9 or a deflection roller unit 10 is designed with a spring-loaded bias. As a result, different expansions or elongations of a plurality of support belts 6 can be compensated for one another during operation of the elevator installation 1.
  • An embodiment of the attachment of the deflection roller unit 10, as shown in FIG. 4, provides that a spring 24 arranged on the tension bolt 20 makes it possible to compensate for different expansion or elongation of the suspension belt 6.
  • the tension bolt 20 is hinged at both ends via a ball socket.
  • the attachment leads at one end of the tension bolt 20 to the car or to the counterweight and at its other end to the cylinder 18 of the pulley unit 10th This is advantageous because the deflection roller unit 10 can adjust in accordance with a withdrawal direction of the support means 6 and the tension bolt 20 is thus substantially freed from bending stresses.
  • the guide roller 11 is shaped according to an embodiment of the support belt 6. It has a smooth deflection surface or a structure. If necessary, it is provided with lateral shoulders. The person skilled in the art defines the design corresponding to the requirement for traction, noise or guidance accuracy.
  • the center axes AZ of the plurality of deflection rollers 11 arranged on the car 2 or the counterweight 3 are arranged on a vertical plane EK.
  • the axes 12 of a plurality of deflection roller units 10 are arranged in a line as viewed from above. Viewed from the side, the axles 12 can be adjusted to different height levels, as can be seen in FIG.
  • the center axes AZ of the guide rollers 11 are arranged on mutually parallel vertical planes EG 1 , EG 2 , EG 3 .
  • the axles 12 of a plurality of deflection roller units 10 are arranged displaced parallel to one another from above.
  • a skew range which as a rule is achieved by tilting the common attachment of the deflection roller units 10, can be increased.
  • the device according to the invention can also be used as a single deflection roller unit at any location in the shaft.
