  • the background for the present invention is safety checks on cargo and passenger tugs. Such lifts must be subjected to regular checks, whereby, for example, characteristic values such as travel paths, braking distances, catching paths and the slip resistance (driving ability) of the cable pull driven by the traction sheave must be determined. This is described in the guidelines for the testing of elevator systems (TRA 102), whereby the TRA 102 are a leaflet of the Federal Minister of Labor and Social Policy.

  • the determined curves can be saved on a data carrier.
  • the evaluation device expediently comprises a computer, preferably a personal computer.
  • the device according to the invention has a force measuring signal transmitter connected to the cable pull, by means of which the forces transmitted by the cable pull and determining the movement sequence of the car can be determined.

  • the rope, the empty car and the counterweight are specifically accelerated or decelerated for checking the adhesion of the rope to the traction sheave during normal operation of the elevator.
  • the movement parameters of the rope and the traction sheave are recorded separately depending on the time.
  • the movement parameters of the rope and traction sheave are also compared with a predetermined limit movement parameter (e.g. a limit curve), the drive capacity of the traction sheave being fulfilled in any case if this limit value is exceeded.
  • a predetermined limit movement parameter e.g. a limit curve
  • the reference numeral 1 designates a traction sheave which has two guide grooves for a cable pull 2 formed in the present case by two cables.

  • the direction of rotation can be determined by evaluating the measurement signals emitted by both light barriers. Such an evaluation circuit is shown in FIG. 6. In addition to path impulses, the number of which is characteristic of the travel path of the car, the circuit also supplies a signal indicating the direction of movement of the car.
  • Fig. 12 shows an embodiment for a double-path transducer which combines the two transducers 7 and 18 in one unit.
  • the two distance sensors are displaceably supported against each other and can thus be pressed with the tread 45 both against the traction sheave and with the running groove 22 'against a supporting cable.
  • the mode of operation of the individual distance sensors corresponds to the sensor in FIGS. 3 and 4.
  • the force measuring signal transmitter has a helical compression spring 28 guided in a guide sleeve 27, which can be compressed by a pull rod 29 which has a disc 30 at one end against which the spring 28 comes into contact and an eyelet 31 at the other end.
  • 32 with a distance transducer is designated by which a displacement of the pull rod 29 against the guide sleeve 27 can be detected and thus a measurement signal for the force acting on the pull rod can be supplied.
  • the Wegslreckenaufillon 32 is shown separately in Fig. 8. Like the distance sensor according to FIGS. 3 and 4, it has a perforated disk 19 'and two light barrier measuring devices 25' and 26 '.
  • the perforated disc 19 ' is connected via an axis of rotation 24' to a drive wheel 33 which comes to bear against the tie rod 29 and is driven by the tie rod.
  • FIG. 9 another embodiment of a force transducer 8 is shown, which differs from the embodiment of FIG. 7 in that a distance sensor is provided for detecting the displacement of the pull rod 29 'against the guide sleeve 27', one with the Drawbar 29 'connected, against the guide sleeve displaceable perforated strip 35 with equidistantly arranged in a line light passage holes 20'.
  • a first light barrier device 25 ′′ and a second light barrier device 26 ′′ are provided for scanning the through holes 20 ′.
  • the connection of the force transducer 8 to the cable 2 and its support on the ceiling 11 is analogous to FIG. 7.
  • the direction of movement of the pull rod can be determined.
  • FIG. 10 shows a further exemplary embodiment of a dynamometer 8, which corresponds in terms of arrangement to the exemplary embodiment according to FIG. 7 and differs from it in that the force between the point of application 34 and the elongated holes of the belt fastening 37a is not direct acts on the spring, but is deflected via the joint 35 and presses on the support balls 36 on the plate springs 38.
  • the plate springs 38 are guided through a sleeve 39 on the outside.
  • the transducer holder 40 is used Recording the distance sensor (dial gauge) 50 according to FIG. 11.
  • the distance sensor dial gauge
  • it has a perforated disk 19 and two light barrier measuring devices 26.
  • the perforated disk 19 is driven by the rack 42 via the gear 43.
  • a return spring is used to eliminate the play between gear 43 and rack 42.
  • this distance transducer can be fixed to the transducer receptacle 40 of the dynamometer FIG. 10 and there it senses the spring travel, translated by the lever ratio joint 35 - support ball 36 - transducer receptacle 40.
  • measurements of travel distances, speeds and accelerations of the car as a function of time or of the path can be carried out as a function of the signals of the control circuit of the elevator system that control the movement of the car carried out and recorded.
  • These curves can be output on the computer screen or on a printer. By comparing with the target curves, statements can be made about the effectiveness of the brake and safety gear.
  • FIG. 13 shows a typical course of a path (s) over time (t) curve (f), as it was recorded during a catching process. As shown in FIG. 13, this curve (f) is output on the screen or on the printer.
  • Two consecutive braking distance measurements can be used to calculate the braking distance of the car loaded with nominal load in the down direction. It is also possible to calculate the braking deceleration when the car is loaded with 1.5 times the nominal load. This is possible because these different braking distances (sleer from to sleer up) are caused by known mass differences. All other masses involved (including rotatory ones) are equally involved in both experiments and can therefore be eliminated. Speeds can also be determined, since the respective times are also stored in a table in the computer for the corresponding routes. The braking distance or deceleration at any load can therefore be calculated by two braking attempts with an empty car. It is therefore possible to make a statement about the brake under load from the empty car.
  • the delay under vice This delay in turn determines the dynamic portion of the driveability test with load. Since this deceleration can be calculated and the decelerated masses (car, counterweight) are known, the dynamic component can also be calculated and replaced by an additional force when testing the driving ability without load.
  • the slip resistance (driving ability) of the cable can also be determined. 7 or 9 or 10 with one or more cables 2 of the cable pull with the aid of a suitable cable clamp 49.
  • the guide sleeve of the force transducer is fastened to a fixed point via a belt strap 47 and a cross member 48, expediently on the ceiling 11 closing the elevator shaft.
  • the tensile force must be increased in the slip test until either a determined limit value is reached and the signal generator emits a warning signal, or the rope or ropes on the traction sheave start to wear out.
  • the slipping that occurs can be visually e.g. can be determined by shifting applied markings or by evaluating the signals of the first distance sensor that can be connected to the cable pull and the second distance sensor that can be connected to the traction sheave.
  • the driving ability can also be determined in the following manner with the device described:
  • the two distance sensors are each motion-connected with the traction sheave and a suspension cable.
  • the control line 9 is connected accordingly to the elevator control.
  • the elevator is now decelerated from full speed with maximum braking effect. From the time the delay is initiated, the travel sensors record the distances traveled, which are stored in the computer with the associated times in a table. By evaluating these tables, it can then be determined whether or how far the suspension cable has slid over the traction sheave. Furthermore, it can be determined at which delay the static friction has overcome and the slipping has started and at which delay the ropes have stopped again relative to the traction sheave (transition from sliding friction to static friction). Since the delayed masses (ropes, car and counterweight) are known or can be determined, the delays can therefore be extrapolated directly to the corresponding forces. It can also be determined from which load the elevator slips and at which load there is static friction again.
  • both position transducers In order to be able to record path differences, both position transducers must either emit the same impulses for the same distances or be synchronized with a correction factor.
  • the two odometers are automatically calibrated with each measuring process. This is achieved as follows: At the beginning of the The braking process, therefore, before the brake is applied, the elevator moves at an almost constant speed. No additional forces act between the suspension cable and the traction sheave. Both odometers travel the same route. If the number of pulses of the two travel meters is now set in relation to each other, this quotient is the synchronization factor of the two travel meters. This synchronization is implemented using software, for example.
  • the device described is also able to check the control circuit of the elevator by checking the chronological sequence of the control signals. E.g. the time it takes for the control to switch off the drive or to apply a brake after a safety switch has been opened can be determined.
  • the evaluation unit has a number of functional devices, some of which are implemented as software solutions.
  • a functional device is provided for determining the speed and / or acceleration values.
  • the measurement of the speed can be triggered by actuating the keyboard or it is triggered by signals from the control circuit of the elevator. Measurement results can be displayed on the screen of the personal computer and, if necessary, can be output as a complete test report on a printer.
  • the acoustic signal generator contained in the interface module 14 can be activated.
  • the screen can also be used to display instructions for operating the device.
  • the sensor interface causes the computer when an external event occurs, e.g. Advance the perforated disc to interrupt its work and update the corresponding internal memory for distance and possibly time.
  • an external event e.g. Advance the perforated disc to interrupt its work and update the corresponding internal memory for distance and possibly time.
  • timers and acoustic signal generators with the necessary control were accommodated in the sensor interface.
  • dispensing with these modules and, instead, controlled by software, using the corresponding modules in the computer.
  • the device and the method according to the invention enable the travel movement of an elevator to be very finely determined with regard to the distance covered and the associated time. Accelerations and decelerations can be recorded in a very fine time grid.
  • the empty car can be braked during the upward travel, with an operator holding a distance sensor 7 against the running suspension cable before and during the deceleration.
  • the fact whether the suspension cable slips on the traction sheave or not can be assessed visually in this case by marking the position of the suspension cable on the traction sheave with a line before the deceleration.
  • the empty elevator car is either accelerated or decelerated.
  • the brake of the elevator is held in the standby position by a brake magnet that is constantly energized. If the power supply to the brake magnet is interrupted for the test procedure, the brake starts. The intended interruption of the current supply for the magnet can be used as a trigger for starting the measuring process.
  • the short period between the interruption of the power supply and the subsequent intervention of the brake can be used to synchronize the distance sensors for the traction sheave and for the rope. During this short period of time there is a constant speed in both parts. During this period, the two distance meters assigned to the support cable and the traction sheave are synchronized by setting the number of counts of the one distance meter in comparison to that of the second knife. The factor determined in this way is used to convert the counting pulses of both sensors into sections. Any manufacturing tolerances between the two odometers as well as different wear are automatically eliminated.
