Definitions

  • the invention relates to a method for preventing a run-up of two elevator cars which can be moved in the same shaft of an elevator installation and to an elevator installation which can be operated according to the preamble of claim 6.
  • Elevator systems with several elevator cars in the same shaft which are also referred to as multi-mobile elevator systems, usually each have a drive and brake system per elevator car. Furthermore, such elevator systems are equipped with a collision protection system by which collisions of the elevator cars are to be avoided.
  • the emergency stop system should be designed as far as possible so that it does not cause an enlargement of the shaft cross-section.
  • the new elevator system has at least one upper elevator car and a lower elevator car.
  • the two elevator cars can move up and down vertically in a common elevator shaft of the elevator installation, essentially independently of one another.
  • the upper elevator car has a first drive and brake system, which comprises a first holding brake (preferably an engine brake).
  • the lower cab has a second drive and brake system that detects a second holding brake (preferably an engine brake).
  • the first elevator car is equipped with a first (emergency) brake and the second elevator car is equipped with a second (emergency) brake, the function of which will be explained below.
  • the elevator system has a collision protection system in order to avoid collisions between the elevator cars.
  • the collision protection system preferably comprises a first electro-mechanical switching mechanism on the upper elevator car, and a second electro-mechanical switching mechanism on the lower elevator car, with which a deceleration of the upper elevator car by the first holding brake and / or a deceleration of the lower elevator car through the second holding brake can be triggered.
  • the elevator cars and the collision protection system according to the EP-06120359 be educated.
  • an emergency stop system is also provided.
  • the emergency stop system is designed so that it continuously or repeatedly determines the instantaneous state of motion of the two elevator cars after triggering the delay or braking by the holding brakes and triggers an additional braking of one or both moving elevator cars by means of an associated cabin brake, if so taking into account the movement state of the elevator cars on the one hand and taking into account definable braking criteria on the other hand is necessary.
  • the state of motion of the elevator cars is essentially a function of their relative speed.
  • Braking criteria can be set in advance in principle, but advantageously the current state of motion of the elevator cars is included.
  • Fig. 1 shows a simple elevator system 10.
  • the elevator installation 10 has an elevator shaft 11 in which an upper elevator car A1 and a lower elevator car A2 can move vertically.
  • a critical minimum distance d (0) between the two elevator cars A1, A2 is maintained, ie during a normal operation where the instantaneous distance di is greater than the critical minimum distance d (0), the elevator cars A1, A2 can move independently of one another in the Move elevator shaft 11.
  • the elevator installation 10 has a drive and brake unit, wherein preferably each of the pull-out cabins A1, A2 has its own drive and brake system.
  • the elevator installation 10 also has a collision protection system 20.
  • the collision protection system 20 comprises a first electro-mechanical switching mechanism 21, which is arranged in a lower region of the upper elevator car A1, and a second electro-mechanical switching mechanism 22, which is in an upper Area of the lower elevator car A2 is arranged.
  • the two switching mechanisms 21, 22 are vertically aligned one above the other.
  • the collision protection system 20 of the elevator installation 10 preferably has per elevator car A1, A2 its own safety circuit, in which several safety elements, such as safety contacts and switches, are arranged in a series connection.
  • the corresponding elevator car A1 or A2 can only be moved if its safety circuit and thus also all safety contacts integrated in it are closed.
  • the safety circuit is connected to the drive and brake unit of the elevator system 10 or the drive and braking systems of the elevator cars A1, A2 in order to interrupt the driving operation of the corresponding elevator car A1 and / or A2, if the safety circuit by pressing the corresponding electro mechanical switching mechanism 21 and / or 22 is opened.
  • the first switching mechanism 21 comprises a weighting body 23 having a weight G suspended from an elongated flexible support member 24, which in turn is secured to the lower portion of the upper elevator car A1.
  • the overall vertical dimension of the support member 24 and the weight body 23 substantially corresponds to the critical distance d (0) to be maintained between the elevator cars A1, A2.
  • the second switching mechanism 22 comprises a mechanical sensor in the form of a lever 28 (see Fig. 2 ), which acts on a contact switch 34.
  • the weighting body 23 hangs freely on the support element 24, which is under tension by the weight G of the weighting body 23 and is kept stretched.
  • the safety circuit of the first drive and brake unit of the upper elevator car A1 is opened. This triggers the braking of the upper elevator car A1 by means of the first holding brake (designed, for example, as an engine brake).
  • the safety circuit of the second drive and brake unit of the lower elevator car A2 is also opened practically at the same time. As a result, the deceleration of the lower elevator car A2 is triggered by means of the second holding brake (designed, for example, as an engine brake).
  • the emergency stop system according to the invention can also be used in elevator systems 10 whose collision protection system is designed differently or whose holding brakes can be triggered in other ways and / or which are equipped with a safety bus system instead of the mentioned safety circuits.
  • the elevator installation 10 has, in addition to the collision protection system 20, the emergency stop system by which an additional deceleration of the moving elevator cars A1 and / or A2 is achieved after the deceleration of one or both elevator cars A1, A2 by one or both holding brakes can.
  • the triggering of this additional delay takes place taking into account the current state of motion of the elevator cars A1, A2 and on the basis of the emergency stop criteria.
  • the emergency stop system of the invention may include structural elements of a collision protection system 20 and additional structural elements. That is, in this case, the emergency stop system is at least partially integrated with the collision protection system 20.
  • An emergency stop or braking by one or both cab brakes is triggered, in addition to the braking by the holding brakes, if one of the two following emergency stop criteria is met:
  • Fig. 3 shows a diagram with which the flow of the entire braking process using both the holding brakes and the cabin brakes is exemplified.
  • question Q2 is answered with no N, ie if only one of the elevator cars is in motion, then question Q3 is asked.
  • question Q4 is answered with no N, question Q2 is asked again.
  • question Q2 is answered with yes J, ie if both elevator cars A1 and A2 are in motion, then question Q5 is asked.
  • question Q4 is asked for further clarification, that is, question Q4 clarifies whether the relative speed vi (rel) of the elevator cars A1, A2 is zero. If this is the case, then according to box F4 no additional braking with cabin brakes is necessary.
  • a corresponding emergency stop system can also be set up between these elevator cars.
  • Fig. 4 a presently particularly preferred embodiment of an essential part of the emergency stop system 21 is shown. It can be seen the role 30, on which the support means 24 winds up when it is not burdened by the weight of the hanging weight body 23 thereon. On the same shaft 42 as the roller 30 sits a spring output 31, which is also referred to here as energy storage. About a clutch 40, an incremental encoder 32 is grown. The connection is made via an adapter 41.
