Definitions

  • the invention relates to a switch-off device for an escalator for initiating the stoppage of an endless, consisting of several steps and two link chains arranged laterally next to the steps, guided between two balustrade sockets, a walkable lead with two horizontal runs, an inclined run and two transition arches, which step immediately comes into effect if it detects a malfunction of the moving step belt or a defect in the step belt.
  • each escalator must have a number of monitoring and shutdown devices. For example, the backward running of an upward escalator must be prevented, or a downward escalator must not exceed the normal speed by more than 20% and it must be stopped automatically when this excess speed is reached. An escalator must also be switched off when a step descends, i.e. if, for whatever reason, the step surface of a step would no longer be guided through the comb in a perfectly horizontal position.
  • DE-PS 628 503 has disclosed such a device for switching off an escalator, which responds by approximately 20% when the normal speed selected between two predetermined step belt speeds is exceeded.
  • the step belt is moved by a DC motor, which drives the main shaft via a reduction gear and a chain gear.
  • a governor working according to the centrifugal force system is driven by a chain from the main shaft and monitors the driving speeds, whereby an electromagnet adjusts a regulator sleeve of the regulator in accordance with the selected normal driving speed, so that the regulator only responds at both adjustable driving speeds and stops the escalator when an approximately equal excess speed occurs.
  • a selector switch for a small and a high speed and a direction switch are accommodated in an apparatus cabinet.
  • EP-PS-082 074 Another device for switching off an escalator has become known from EP-PS-082 074, in which each individual step is monitored with the aid of at least one distance sensor arranged in the return of the step band, in conjunction with a logic circuit. In the absence of a step, the logic circuit triggers a false signal at the command of the distance sensor and causes the escalator to be shut down immediately via a relay.
  • the invention is therefore based on the object of proposing a device for switching off escalators, by means of which a plurality of independent safety devices can be monitored and by means of which the escalator is switched off when one of the monitored safety devices responds.
  • a balustrade of an escalator arranged on both sides of a step belt 3 is designated by the number 1.
  • the step belt 3 consists of a number of steps 4, which are fastened between two endlessly circulating link chains 5, each to one of the step axes 13 connecting the two link chains 5, and forms an accessible feed and a return.
  • the advance of the step belt 3 is in turn divided into a lower horizontal run 3.1, an upper horizontal run 3.2, an oblique run 3.3 and a lower and an upper transition curve 3.4, 3.5.
  • Each stage 4 always has a step 3 that can be entered in advance horizontally guided tread surface 4.1, a riser 4.2, two side plates 4.3, two chain rollers 6 mounted on the step axis 13 between the plates of the plate chain 5 and two drag rollers 7.
  • the chain rollers 6 are placed on a chain guide 14, the drag rollers 7 on a roller guide 15.
  • the lead of the step belt 3 is guided between two balustrade bases 2 arranged below the balustrades 1.
  • a light barrier 8 with a transmitter 10, a receiver or reflector 11 and one which is emitted transversely to the direction of travel of the step belt 3 is emitted on both sides of the balustrade base 2 Beam of light 12 installed.
  • a light barrier 9 with a transmitter 10, a receiver or reflector 11 and a light beam 12 is provided on both sides of the balustrade base 2 at the lower end of the skew 3.3 of the step belt 3 before the transition to the lower transition arch 3.4.
  • the position of the light barrier 8, 9 is selected such that the light beam 12 is directed directly over the link plates of the link chain 5 transversely to the step belt 3 from one balustrade base 2 to the other and interrupted by each step 4 between the bearings of the chain rollers 6 and the riser 4.2 is, while it can be received between the riser and the bearings of the chain rollers 6 of the adjacent stage 4 unhindered by the receiver 11 of the light barrier 8, 9.
  • the device described above works as follows:
  • the light barriers 8, 9 installed in the skew 3.3 of the step belt 3 in front of the upper transition arch 3.5 or in front of the lower transition arch 3.4 in the balustrade bases 2 are monitored by a known electronic evaluation circuit.
  • the step belt 3 drives past the upper light barrier 8 for the upward escalator, or the lower light barrier 9 for the downward escalator, the periodically received light-thinking intervals with a light-dark pattern stored for the corresponding normal operation compared and evaluated. If there is any change in the intervals or the pattern, e.g.
  • the escalator is switched off immediately and stopped by the normal service brake.
  • the distance between the light barriers and the tip of the comb is selected so that it is greater than the distance traveled, for example one of the Device for switching off an escalator as a defective step until it comes to a standstill, or an escalator running at approx. 20% overspeed from the moment of the detected overspeed until the escalator comes to a complete standstill.
