  • 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.

  • Two consecutive braking distance measurements can be used to calculate the braking distance of the car loaded with nominal load in the direction from. 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 rotary) 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. Two braking attempts with an empty car can therefore be used to calculate the braking distance or braking deceleration for any load. It is therefore possible to make a statement about the brake under load from the empty car.

  • the onset of slides can visually e.g. B. by shifting applied markings or by evaluating the signals of the first with the cable and the second with the traction sheave connectable distance sensor.
  • 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 out decelerated at full speed with maximum braking effect. From the time the delay is divided, 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 braking process, before the brake is applied, the elevator moves at an almost constant speed. No additional forces act between the suspension cable and traction sheave. Both odometers travel the same route. If the number of pulses of the two travel meters is now put 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 transmitter 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 recorded very precisely with regard to the distance covered and the associated time. Accelerations and decelerations can be recorded in a very fine time grid.
  • 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 or not the suspension cable slips on the traction sheave can be visually assessed 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 counting pulses from both sensors into sections. Any manufacturing tolerances between the two odometers as well as different wear and tear are automatically eliminated.
