Definitions

  • the invention relates to an electromechanical monitoring device for detecting an unwanted drive away an elevator car from a standstill, a suitably equipped speed limiter and elevator system, a retrofit device for retrofitting an elevator installation with such a device and a corresponding method according to the independent claims.
  • An elevator system is installed in a building. It consists essentially of an elevator car, which is connected via suspension means with a counterweight or with a second elevator car. By means of a drive which acts selectively on the suspension means, directly on the elevator car or the counterweight, the elevator car is moved along, substantially vertical, guide rails.
  • the elevator system is used to transport people and goods within the building over single or multiple floors.
  • the elevator system includes devices to ensure safety of the elevator system.
  • a device protects, for example, when stopping in one floor of the building, the elevator car from unwanted drifting away.
  • braking devices are used, which can slow down the Aufzugzugababine in case of need.
  • the device consists of a clamping device which clamps a moving part at a standstill of the elevator car, a motion sensor which detects a movement of the clamping device and a control device which evaluates the movement and actuates a safety device in case of need.
  • the present invention aims to provide an alternative monitoring device for detecting an unwanted drive away of an elevator car from a standstill, which is easy to install and which is also suitable for retrofitting in an elevator system if necessary.
  • the electromechanical monitoring device includes a follower wheel, which is pressed in case of need to a track of the elevator car.
  • a follower wheel is pressed in case of need to a track of the elevator car.
  • Such a requirement is, for example, a stop in one floor.
  • the electromechanical monitor is in a normal position, i. the Mitlaufrad is distanced from the track and thus does not touch the track.
  • the electromechanical monitoring device is placed in a ready position, i. the follower wheel is pressed against the raceway, whereby it is rotated in a movement of the elevator car according to a direction of movement.
  • the monitoring device further includes a sensor, which detects a rotation of the follower wheel by a predetermined angle of rotation. If the sensor determines that the predetermined angle of rotation has been exceeded, a brake device, preferably a second brake device, is actuated or another action is initiated which fixes or brakes the elevator car. The electromechanical monitoring device is then in its release position.
  • the second braking device may be, for example, a car brake or a safety device which is arranged directly on the elevator car and which is able to hold the elevator car in cooperation with a wall of the elevator shaft or a guide rail of the elevator car, etc.
  • the use of the Mitlaufrades which is pressed in case of need to the track of the elevator car, is advantageous because as a career any track or surface in question comes into question, which runs continuously over the travel path of the elevator car, or represents the route of the elevator car.
  • the Mitlaufrad can be easily designed and is correspondingly low in procurement.
  • a rotary encoder can be used, wherein a rotation angle of the follower wheel is detected.
  • the braking device is triggered when exceeding a preset angle of rotation. If necessary, two or more rotation angle be preset. In this case, when exceeding a first angle of rotation on the follower wheel, the braking device is actuated and when exceeding a further value, for example, a hoe could be extended, which clings in the areas of the elevator door or rail fasteners, etc.
  • a equipped with such a monitoring system elevator system is particularly safe and cheap secured in relation to a drifting away of the elevator car from a stop and it is ideally suited to be installed in an existing elevator system, or retrofitted. If necessary, an existing braking device can be controlled. If no appropriately controllable braking device is present in the elevator, at most an electromechanical actuation, as for example EP0543154 is known to be installed to an existing braking device or it can of course be installed a new remote-controlled brake.
  • a corresponding retrofit device of the monitoring system advantageously includes a support, which includes the required bearings for moving parts, such as a rocker for receiving the Mitlaufrads, etc.
  • a support which includes the required bearings for moving parts, such as a rocker for receiving the Mitlaufrads, etc.
  • Such a retrofit device can be easily made and attached to a track of the elevator car. Further mechanical adjustments are not required because a driving of the Mitlaufrads alone frictionally carried out by pressing the wheel to the track.
  • the retrofitting device advantageously also includes a corresponding electronics box, which contains the necessary circuits for controlling the monitoring device and energy supply units with memory.
  • the follower wheel drives a cam disk.
  • the cam can hereby be assembled directly with the Mitlaufrad.
  • the sensor advantageously an electromechanical switch in this embodiment, is now simply actuated by a cam of the cam disk when the follower wheel or the associated cam disk is rotated.
  • the follower wheel if necessary together with the cam disc, is automatically moved to a neutral position or zero position as soon as the follower wheel is distanced from the raceway.
  • This can be done for example by a spring device or advantageously the Mitlaufrad, or the associated cam plate is designed so that a center of gravity, the cam, or the cam inevitably twists back to the neutral position or zero position.
  • the preset rotation angle corresponds to half a revolution of the follower wheel.
  • a single electromechanical switch can detect a drifting away of the elevator car in both traversing directions. This embodiment makes it possible to provide a very cost-effective and safe monitoring device, since in particular its function is also easy to understand and comprehend.
  • the electromechanical switch is a commercial latching or bistable switch. This means that the switch remains in the switched position after an actuation until it is returned to the normal or working position either manually or by a corresponding remote reset device.
  • this switch is designed so that a circuit for controlling the braking device is closed in the normal or working position and is interrupted accordingly in the actuated or switched position. In this way, the best safety can be achieved, as an interruption in the control always leads to braking.
  • the follower wheel is pressed by means of a pressure spring to the raceway of the elevator car and it is kept distant by means of an electromagnet of the track.
  • the electromagnet is designed such that it can pull the follower against a spring force of the pressure spring.
  • control of the electromagnet is usually equipped with an energy storage, such as a battery, to keep at a power failure in the building the Mitlaufrad, at least during a run after the elevator car to a stop, distanced from the track.
  • an energy storage such as a battery
  • the follower wheel is pressed by means of a weight mass to the track of the elevator car and it is held by means of an electromagnet away from the track.
  • the electromagnet is designed such that it can pull the counter-wheel against a weight mass of the track. This results in a particularly cost-effective and safe execution, since the weight is always safe and available worldwide.
  • This system also corresponds otherwise to the embodiment as explained in connection with the pressure spring, wherein, of course, when installing in an elevator installation, the mounting position has to take into account the course of the weight.
  • the follower wheel or the raceway to which the follower wheel can be pressed, structured, grooved, roughened or be randriert to ensure safe driving of the follower can of course also be made of a material with a high coefficient of friction, such as polyurethane or coated.
  • the track of the elevator car corresponds to a circumference of a speed limiter and the speed limiter is connected to a limiter rope to the elevator car, or connected.
  • This rope rotates the speed limiter in accordance with a movement of the elevator car, whereby the movement of the circumference of the speed limiter directly represents the career of the elevator car.
  • the electromechanical monitoring device is accordingly arranged at the speed limiter or installed directly at the speed limiter, wherein the idler is pressed in case of need to the periphery of the speed limiter.
  • the monitoring device is particularly simple in an existing Elevator installation or attachable, since the device can be mounted stationary in the building and associated electrical wiring can be performed in an elevator control.
  • a replacement speed limiter for an existing elevator installation can now be provided directly.
  • only an existing speed limiter without monitoring device can be exchanged with the new speed limiter with monitoring device.
  • the monitoring device can also be attached to any other disc which is in connection with the elevator car and rotates in accordance with a movement of the elevator car.
  • a disk may be, for example, a traction sheave, a reversing or deflecting roller, a carrying roller or a guide roller.
