Definitions
- the invention relates to a method and a device for determining the Ablegereife a support means of a lift.
- the car call signals are detected and used to calculate the travel times that the car needs to travel from the call floors to the destination floors. Subsequently, the calculated travel times are compared with wear values in order to determine the manhole section in which the car moves the most frequently. Based on this finding, the wear of the corresponding cable section is now examined.
- this embodiment has the following disadvantage. Due to the fact that the travel time depends not only on the slip, but additionally on some other parameters, such as the load in the cabin, you can conclude by the detection of driving time only relatively inaccurate on the prevailing slip. If the travel time is prolonged, this can have different causes. Greater slippage is just one of several possible causes. Presentation of the invention
- An object of the invention is to provide a method and a device for determining the Ablegereife a Tragmit- means of a lift, with the Ablegereife the support means is particularly precisely determined.
- the suspension element is divided into several sections. For each of the sections, it is determined whether the section passes the drive pulley and / or one or more of the pulleys during a trip, and if so, a degree of ripeness representing the discard condition is increased accordingly.
- the inventive device for determining the Ablegereife comprises in addition to the above-mentioned features a controller for controlling the elevator and an evaluation unit which is connected to the controller.
- the evaluation unit is designed and operable such that it determines the degree of ripeness for each of the sections on the basis of the data received by the controller about the travel destinations.
- the type of bending is determined and, in the case of taken into account for a specific determination of the degree of maturity. This is particularly advantageous in the case of counterbends because they allow the suspension element to be particularly heavily worn.
- a backbend in the determination of the degree of ripeness is taken into account more than a simple bending.
- the wrap angle is taken into account in the section-wise determination of the degree of ripeness.
- the determination of the Ablegereife can be made even more precise.
- the diameter of the deflection rollers is taken into account in the section-wise determination of the degree of ripeness. This also allows the determination of the Ablegereife made even more precise.
- a service message is generated when the maturity level for one of the sections has exceeded a certain value. In this way, regular manual checks of the with the
- the support means is additionally monitored by an optical control device.
- the determination of the Ablegereife can be made even more precise and secure.
- FIG. 1 shows a simplified illustration of an elevator with a traction sheave.
- FIG. 2 shows the counting principle for an elevator according to FIG. 1.
- FIG. 3 shows a simplified illustration of an elevator with four deflection rollers.
- FIG. 4 shows a table and a diagram with four runs of the elevator according to FIG. 3.
- FIG. 5 again shows the diagram with the four rides of the elevator and below a travel table.
- FIG. 6 shows a diagram with the positions of the deflection rollers on the individual cable sections.
- Figure 7 shows a flow chart for the method for determining the Ablegereife a support means of a lift. Ways to carry out the invention
- a suspension element for example an aramide rope
- corresponding tests are carried out in advance and empirical values are used.
- the arrangement of the traction sheave, the deflection rollers, the cable guide, the wrap angle, the traction sheave and the deflection roller diameter have an influence on the stability or the wear.
- the knowledge gained from this leads to a bending cycle number that indicates the maximum number of bending cycles that are permitted before the suspension element is ready for disposal.
- the bending cycle number is also referred to below as the limit bending cycle number. The more often the suspension element is bent, the greater is its wear.
- the permissible number of bending cycles of that support means section which is the most stressed plays a special role. As long as the bending cycle number of the most heavily loaded support means section is not exceeded, the support means need not be replaced.
- deflection rollers In the embodiments of the invention described here, all types of rollers are referred to as deflection rollers. For example, deflection rollers should fall under the term deflection rollers.
- FIG. 1 shows a simplified representation of an elevator with a 1: 1 suspension.
- a cabin 8 is connected to a counterweight 9 via a suspension element 5, which is also referred to below as a suspension cable or shortly as a cable.
- the support means 5 may also be a belt or belt and is guided over a traction sheave 20.
- the suspension element 5 is driven via the traction sheave 20, which is coupled to a drive, not shown.
- the cable section Ai as shown in FIG. 1, is located underneath the traction sheave 20.
- the cable section Ai carries the reference symbol Ai (t ⁇ ) in this position.
- the cabin 8 is located on the floor 11 and the cable section Ai is now partly on the traction sheave 20.
- the cable section Ai carries the reference symbol Ai (tl) in this position.
- the control of the elevator by means of an elevator control 31.
- the determination of the Ablegereife the support means 5 by means of an evaluation unit 32, which is connected to the elevator control 31.
- the support means 5 is first divided into as many sections Ai as there are floors. Then each floor is assigned that portion of the suspension element which lies on the traction sheave 20 when the cabin 8 is in the corresponding floor. Thus, for example, that support means section which on the traction sheave 20 when the car is on the floor 12, the section number A12 is assigned.
- a storage space is assigned to each floor or the corresponding support means section in which each entrance to the floor, each exit from the floor in the opposite direction and each passage of the corresponding floor is counted.
- this is shown graphically.
- On the left is the shaft with a total of 25 floors (-2 to 22) shown, right next to a symbolic representation of a first drive 1 of the cabin from the floor 0 to the floor 8.
- the corresponding memory is shown, the be also referred to as Biege Call Congress Inc.
- the memory comprises as many memory locations as the building floors has less than one, that is, in the present exemplary embodiment, a total of 24 memory locations SP1 to SP24 for a total of 24 cable sections A1 to A24.
- the first cable section Al is located at the counterweight 9 and the 24th cable section A24 at the cabin 8.
- the car 8 moves from the floor 0 to the floor 8 during the journey 1.
- the evaluation unit 32 receives the floor information (call information) from the elevator control 31 and then increases the contents of the corresponding eight memory locations SP3 to SP10 by the value of one.
- the car 8 moves from the floor 8 by three floors further up to the floor 11.
- the cable sections All to A13 are moved over the traction sheave 20 and thereby subjected to a bend. Therefore, the values in the next three memory locations SPI1, SP12 and SP 13 are also increased by the value one.
- the cabin moves from floor 11 down to floor -1.
- the values in the corresponding memory locations SP13 to SP2 are again increased by the value one.
- the car moves up to the floor 3 during travel 4, so that the values in corresponding memory locations SP2 to SP5 are again increased by the value one.
- the largest value in the bending change memory corresponds to the maximum number of bending cycles of the elevator installation.
- a total of three memory locations SP3, SP4 and SP5 are assigned the value 3. This means that during the four journeys the three support means sections A3, A4 and A5 were each subjected to a bending cycle three times.
- a degree of maturity R (Al) 0
- the suspension element section A2 2
- the support center section A3 a maturity R (A3) 3.
- the call information from the elevator control 31 can be used and evaluated. For example, a gray code can be used for this purpose.
- the described embodiment can be integrated into the elevator control 31 or executed as a separate appliance, which is equipped with a corresponding interface to the elevator control 31.
- the floor information can then be transmitted via the interface.
- the elevator control 31 and the evaluation unit 32 can be combined in the same housing or in the same module.
- the individual cable sections can be loaded in addition to the bends via the traction sheave with bends over the pulleys on the counterweight or on the cab.
- the pulleys are also referred to here as Pulleys or pulleys. In the second embodiment described here, these bends are not counted separately. It is assumed that each section of cable is bent both over the pulley and over the pulleys on the counterweight or cab. For this reason, it is spoken of bending cycles and not bending bends.
- One bend cycle includes both the bend over the traction sheave and the bends over the corresponding pulleys.
- a separate limit bending cycle number is determined for each elevator layout (disposition) by means of corresponding service life tests with defined traction sheave and pulley diameters.
- FIG. 3 shows in simplified form a lift with a 2: 1 suspension.
- the support cable 5 is attached to a first attachment point 6 on the shaft and leads via a first guide roller 1, which is secured to the counterweight 9, via a traction sheave 2, which is fixed to the shaft and further deflection rollers 3 and 4, on the
- Bottom of the cabin 8 are arranged, to a second attachment point 7 in the shaft.
- the shaft is after th by a bottom 10 and bounded above by a ceiling 13.
- FIG. 4 shows a table and a diagram with four journeys F1-F4 of the elevator.
- the shaft height for example, in meters and right next to it, the floors are given as numbers 0 to 50.
- the floors are given as numbers 0 to 50.
- the car 8 moves from the floor 0 to the landing 8.
- the car continues to the floor 32.
- the cabin moves on to the floor 25.
- the fourth drive F4 finally drives the Cabin back to floor 0.
- the positions of the three pulleys 1, 3 and 4 as well as the traction sheave 2 on the rope 5 are given as absolute values in meters relative to the beginning of the rope at attachment point 6.
- Figure 5 again shows the diagram with the four trips Fl to F4 of the elevator and below the resulting trip table. It can be seen from this table which position the four pulleys 1 to 4 have at the beginning of the respective journey (start) and at the end of this journey on the carrying cable 5.
- the deflection roller 1 is 0.8 m from the beginning of the rope (attachment point 6).
- the guide roller 1 is then 24.8 m from the beginning of the rope. This means that there are 24.8 m of rope between the deflection roller 1 and the attachment point 6. The rope is thus at the time Fl from
- Pulley 1 on the route between 0.8 m and 24.8 m overrun. From the travel table shown in Figure 5, the diagram shown in Figure 6 can be derived, in which the positions of the pulleys 1 to 4 are shown on the individual cable sections Al, A2, A3 to AN.
- Figure 7 shows a flow chart for the method for determining the Ablegereife the suspension element of an elevator.
- the rope 5 is divided into N sections Al to AN and the positions of the pulleys 1 to 4 on the rope are assigned to each floor 0-50.
- the attachment point 6 forms the zero point or reference point. However, the reference point can also be any other location, such as the attachment point 7. Thereafter, the overrun rope length is recorded for each trip Fl to F4 and each pulley 1 to 4 (see FIG. 5).
- Those cable sections with the most or most damaging bending changes can be detected at any time.
- a limit can be set for the permissible damage, ie for the permissible number of bending changes.
- S5 When this number is reached (S5), a service message can be issued (S6) to indicate that the suspension means should be replaced.
- S6 When this number is reached (S5), a service message can be issued (S6) to indicate that the suspension means should be replaced. But it can also be determined only the section on the rope, which has received the greatest damage. In the latter case, this cable section can then be visually or by means of auxiliary equipment, e.g. magnetically inspected.
- R (Ai) of the rope section Ai applies in this case:
- R (Ai) SB + 4 * RB
- a support means section Ai is subject to a simple bend when this support means section Ai is bent on one of the deflection rollers or on the traction sheave in a first direction. If this support means section Ai is bent at a later time in the opposite direction, this support means section Ai is then subject to a return bend.
- the suspension element section which is located on the deflection roller 3 in the cabin position POS1 shown in FIG. 3, is subject to a simple bend. Later, when the car is then in the position P0S2, the support means section is located on the traction sheave 2 and is now also subject to a back bend.
- the evaluation unit 32 (FIG. 3) can thus ascertain, on the basis of certain geometries which result from the elevator layout, for example the parameters HI-H4, HQ and BK and the lifting height of the car 8, whether a particular cable section Ai during a journey simple bending and / or a back bend is subjected.
- the diameter of the deflection rollers is marked with the reference symbol D.
- D the diameter of the pulleys
- the wrap angle can also be taken into account when determining the maturity.
- the weighting factor GF can be related to the diameter D of the deflection roller. For a deflection roller with a small diameter D, the weighting factor GF is increased. selects as in a pulley with a large diameter D. Similarly, the weighting factor GF may be related to the wrap angle of the traction sheave.
- the weighting factor GF is selected to be smaller than if the wrap angle of the suspension element on the drive pulley is small.
- the weighting factor can be related to the load hanging on the suspension element. The larger this load, the greater the weighting factor GF is chosen.
- the suspension element 5 can additionally be monitored with an optical control device 30 (FIG. 1). There- Through the determination of the Ablegereife can be made even more precise and secure.
- an optical control device 30 for example, a video camera can be used, but the support means 5 can also be optically controlled by a service technician. In the optical control, for example, attention is paid to wire breaks, bubbles in the bearing support and changes in the geometry of the suspension.
