Definitions

  • the present invention relates to an elevator installation, in which at least one safety system is provided against uncontrolled vertical movements of a load-receiving means or a counterweight of the elevator installation.
  • the safety system comprises at least one safety gear with a braking device, which can be brought into an activated, braking and a deactivated, non-braking state, wherein the safety device in the activated state, the load-receiving means frictionally connects to a guide rail.
  • the non-braking state of the braking device is also referred to as the normal operating state.
  • the safety system comprises at least one activation mechanism activating the brake device.
  • a limiter rope is used, which is guided in the upper region of the hoistway around the sheave of a speed limiter and in the lower part around a Umlenkseilario, one of the extending between these sheaves strands of the governor rope is coupled to an activation mechanism of the safety gear on the load receiving means.
  • the movements of the load receiving means or the counterweight are thereby transmitted via the governor rope on the pulley of the speed limiter, so that during a movement of the load receiving means or the counterweight, this sheave performs a rotational movement whose rotational speed is proportional to the travel speed of the load receiving means.
  • the overspeed governor works by blocking the pulley of the overspeed governor or by activating a rope brake on the overspeed governor if an inadmissible high speed of the load handler or counterweight occurs.
  • the limiter rope and thus the strand of the limiter rope which moves synchronously with the load suspension means or with the counterweight are stopped.
  • the stationary governor rope activates the activation mechanism of the still moving load-carrying means or the counterweight mounted safety gear and the load-receiving means is brought to a standstill.
  • load-carrying means is to be understood below to mean both load-bearing means, such as elevator cars, and counterweights.
  • JP 2000 31261 Another safety device for a driving body is disclosed.
  • the safety device is actuated by a torque detecting device when a force acting on a brake drum torque exceeds a predetermined value.
  • the publication font EP 1 902 993 A1 discloses a safety gear with a locking roller in a pivotable guide device. To catch the elevator car, the locking roller is pressed by pivoting the guide device against a guide rail and clamped or wedged due to the relative movement between the guide rail and guide means between a respect to the guide rail inclined track of the guide means and the guide rail.
  • To activate the safety gear is an electromagnet, which allows a disrupted power supply, a spring-driven movement of the guide means, whereby the locking roller is pressed against the guide rail.
  • the object of the present invention is to provide a safety gear which is optimized in its activation, but if necessary also in their reset function. In particular, it should be achieved that the least possible expenditure of force or expenditure of energy is required to activate the safety gear.
  • the solution of the task consists essentially of a mounted on the load receiving device catching means comprising a cooperating with a guide rail of the load receiving means braking device, which braking device includes a rotatable about a cam axle cam, wherein the safety gear comprises an electrically controlled activation mechanism to activate the safety gear the Turning cam about an activation rotation angle and wherein the cam is designed so that it comes into contact with the guide rail as a result of the rotation about the activation rotation angle, whereby the guide rail moving relative to the safety gear when the load handling device moves the cam rotates into a position, in which the braking device and thus the safety gear generates an intended braking action with respect to the guide rail.
  • the solution has the advantage that for activating the safety gear by an actuator only the cam rotated by a triggering rotation angle and not as in EP 2 112 116 A1 the housing with the entire, heavy safety gear must be moved sideways.
  • the electrically controlled activating mechanism comprises a pivotally mounted activating lever, an electromagnet and an activating spring, the activating lever being fixed by the electromagnet turned on in an initial position corresponding to a normal operating condition of the braking device, and driven by the activating spring by turning off the electromagnet in the direction an end position is movable, wherein the activation lever is coupled to the cam so that the movement of the activation lever from its initial position towards the end position causes the rotation of the cam about the activation rotation angle and thereby brings the cam to the guide rail in contact.
  • the ratio between the holding force that the solenoid can exert in the initial position with the voltage applied to the activating lever to the electromagnetically acting force of the preloaded activating spring is in a range of 1.5: 1 to 3: 1, but is preferably about 2: 1.
  • the electromagnet is thus preferably designed so that it exerts only a secure holding function on the activation lever.
  • one electronic speed limiter for example, in case of overspeed, causes an interruption of the power supply to the solenoid, the activation lever changes from its initial position towards the end position.
  • the activation lever driven by the force of the activation spring causes the cam to rotate, for example by a first contact surface in an end region of the activation lever engaging a driver of the cam.
  • the electromagnet is turned off, whereby the activation lever performs an activating movement from its initial position in the direction of the end position.
  • its first contact surface drives the driver of the cam so that the cam is rotated and leaves its preferably spring-positioned normal position, whereby the periphery of the cam comes into contact with the guide rail.
  • the end portion of the activation lever may have a second contact surface, which becomes effective in the following case. If the cam, for example, due to inaccurate or too elastic guidance of the lifting device in contact with the guide rail device, the cam can be rotated by the guide rail, so that the safety device is activated unintentionally. In such a case, only one of usually two safety gears is activated while the second safety gear remains inactive. In order to avoid this situation, a second contact surface may be arranged in the end region of the activation lever such that the driver of the inadvertently rotated cam causes the associated activation lever to leave its initial position and move in the direction of the end position. This can be detected, for example, by a detector or switch, so that either mechanically or electrically, the second safety gear can also be activated approximately synchronously.

  • the brake device or the caliper is preferably mounted displaceably at right angles to the guide surfaces of the guide rail or the guide web with respect to a support frame of the load receiving means on which the entire safety gear is mounted.
  • the support frame can also be an integral part of the load handling device.
  • the cam plate is preferably a disc mounted on a rotational axis fixed to the brake caliper, the periphery of which has a feathering directed in normal operation against the guide rail flattening, wherein adjoining the flattening a peripheral portion which has an increasing radius with increasing rotational angle.
  • first normal operating state of the safety gear causes the flattening a sufficient distance between the cam and the guide rail.
  • the cam is rotated by the activation lever to the activation angle of rotation, whereby the subsequent to the flattening, increasing in radius peripheral portion of the cam comes into contact with the guide rail.
  • This has the consequence that the cam is further rotated by the relative to the safety gear moving guide rail in a position in which the braking device and thus the safety gear generates a braking effect against the guide rail.
  • a first step is characterized in that the activation lever is no longer held by the solenoid, that is released.
  • the activation spring causes a pivoting movement of the activation lever, whereby the rotatably mounted in the brake caliper cam is rotated by an activation rotation angle, so that the flattening of the cam rotated away from a parallel to the guide rail facing position and adjacent to the flattening, im Radius increasing peripheral portion of the cam comes into contact with the guide rail.
  • the activation spring must be like this be designed so that it can turn the cam about the required activation rotation angle via the activation lever.
  • the contact between the increasing radius in the peripheral portion of the cam and moving relative to the safety device guide rail causes further rotation of the cam until the cam has reached a position in which the cam reinforced by interaction with other elements of the braking device to the Guide rail is pressed and causes the braking device generates an intended braking action against the guide rail.
  • the force of the activation spring of the activation lever is no longer required.
  • at least a part of the peripheral surface of the cam may be provided with a toothing or micro-toothing.
  • the braking surfaces of the brake elements of the braking device are arranged at a small angle to the longitudinal direction of the guide rail, so that when initiating the braking operation in a downward movement of the load receiving means first create the lower ends of the brake elements to the guide rail.
  • vibrations or a chatter or even jumping of the brake elements can be avoided, especially during the downward movement of the load-receiving means.
  • a preferred embodiment variant of a disclosed safety gear has a second spring in addition to the activation spring.
  • This spring may for example be a tension spring, the the cam is positioned yielding in its normal position.
  • this spring is referred to as a retaining spring.
  • the retaining spring is designed and arranged so that the cam is held in its normal position during normal operation of the elevator system.
  • the retaining spring is sufficiently yielding, so that the rotation of the cam by the activation lever or by the guide rail is not hindered.
  • the retaining spring may be coupled to the activation lever such that upon release and subsequent movement of the activation lever, a bias of the retaining spring is reduced.
  • the braking device is vertical, d. H. in the direction of travel of the lifting device slidably mounted on the support frame of the lifting device. This is done, for example, by the braking device is guided by means of support bolts in vertical slots in the support frame.

  • the entire, the electromagnet and the activation lever with its pivot bearing comprehensive activation mechanism is mounted directly to the support frame in the embodiment described here.
  • a further embodiment variant of a disclosed safety gear may include a switch for detecting the brake or the brake device. This switch detects the initial position of the activation lever and is activated during movements of the latter. It thereby gives a signal interrupting the safety circuit of the elevator installation, so that when the brake or braking device is put into operation, the drive of the elevator installation is switched off.
  • the activation spring of the activation lever can be configured instead of a torsion spring as a compression spring, tension spring or bending spring.

  • the speed limiter system 200 provides that when a first overspeed VCK is reached, the roller 28 can no longer completely traverse the valleys between the elevations of the cam 19 and thus the pendulum 26 begins to raise counterclockwise.
  • This erection movement activates a pre-contact switch 29, which electrically switches off and disengages the drive unit 6 via a control line 30 and via a controller 31.
  • the controller 31 is connected to a control device 63 for the entire elevator installation 100, in which all control signals and sensor data flow together.
