Definitions

  • the invention relates to a device for protecting Persons from the danger of being crushed by the Penetration of a transport device in the one or several people temporarily occupied work space.
  • Workrooms of this type are, for example, shaft pits and Shaft heads in elevator shafts. Their temporary occupation by persons is due to the periodic, correct maintenance and Control work on the existing ones in these rooms technical facilities.
  • Relevant regulations, e.g. the EN81, to protect themselves there temporarily people stopping that these rooms are appropriate Dimensions should have, taking into account the full travel distance to the end positions of the transport device sufficient safety height for the person working in it Guarantee staff. But that is not always the case possible, especially when retrofitting elevator systems in existing buildings.
  • the lane limiter is as Stop plate formed with a fastening hook, the is hung there in elongated holes on the guide rails, where the journey of a transport device to protect People must be limited.
  • the patent specification CH 667 638 describes one in the A protective device in the form of a shaft pit pivotable mounting device, in which at Opening the bottom shaft door when one is not present Cabin automatically a stop support in the clearance profile the transport device swivels. This is the Shaft pit area against the intrusion of the Transport device secured and the requested Personal protection in principle. After leaving the Manually, the mounting device is placed in the shaft pit Starting position brought.
  • Facilities of this type consist of mechanical and electrical components throughout Operating time of a transport device its full Must maintain functionality. This Functionality must therefore be checked periodically to ensure that the To guarantee protection. Manual reset there is a certain danger from the inside of the shaft Included when closing the shaft door through a second person from outside and also means one considerable loss of comfort during use.
  • a Protective device of the type described above create their function a safe protection for you Fitter guaranteed, even if he is careless or incorrect operation caused by negligence, the any inoperability is noticed immediately and the is comfortable to use.
  • FIG. 1 shows a cabin 1 in a shaft 2 shown, which on roller guides 4 Guide rails 5 moves in the up and down direction.
  • At 27 is the lowest cabin position indicated, which is the cabin occupies when it goes to the lowest floor level 16.
  • A is located on a buffer base 14 low-friction pivot bearing 11, on which a pivot buffer 8 is arranged vertically.
  • the low-friction pivot bearing 11 can be designed as a knife bearing, as in the mechanical weighing technology is used.
  • the upper Completion of the swivel buffer 8 is in the form of a laterally projecting buffer plate 9, which as a support for an impact edge 6 on the cabin 1 is used.
  • the foot of the Swivel buffer 8 is designed as a buffer lever 10, the after left ends in a joint 29 and its right horizontal Continuation as an actuating finger 30 for two redundant ones Safety switch 13 is shaped.
  • One on the buffer socket 14 attached actuator 12 is on its plunger 31 with the Joint 29 of the buffer lever 10 connected.
  • a thickening of the Diameter of the swivel buffer 8 is about half the height as switching edge 32 for a position switch 15 educated.
  • the swivel buffer 8 In the drawn state, the swivel buffer 8 is in the Actuator 12 shown repelled starting position and the buffer plate 9 is outside one Line of movement 7. In this position of the swivel buffer 8 can the cabin 1 without hindrance to the bottom floor 16 drive. So that the swivel buffer remains in this position, the actuator 12 must be extended in order to have a continuous To exert thrust on the joint 29 and so the To keep swivel buffer 8 in the swiveled back position.
  • FIG 3 shows the usual picture of a shaft door front with a shaft door 17 and one, for example in one Fighter 19 arranged as a triangular pin 18 Lock actuator, which by means of the known Triangular key for unlocking the shaft door 17 is used.
  • the memory circuit is activated via a, on Triangular pin 18 shaped switching curve 22. If the For example, triangular bolts are rotated by 90 ° Latch switch 21 brought into the latch position according to Fig.5 and remains in this position after releasing the Triangular bolt 18, which then, as is common practice, by Spring force turns back to the position shown in Fig. 6. For one Resetting the latching switch is an activation of the Reset element 20 required.
  • the reset element 20 can for example be designed as an electromagnet.
  • 7 and 8 is the front view of the two-stage Arrangement of an unlocking and triggering device 26 shown.
  • FIGS. 9 and 10 The mechanics and function of this two-stage unlocking and Tripping device can be seen from FIGS. 9 and 10.
  • a first triangular pin 18 when it is actuated a pawl 33 over a nose 34 of a shift slide curve 24 raised.
  • Slider 23 are manually pushed to the right, with what second lock actuating element, or a triangular pin 25 is made accessible and at the same time the latching switch 21st is brought into memory.
  • the final The shaft door is only unlocked by the Actuation of the second triangular pin 25.
  • the reset the latching switch 21 is carried out in the same way as already previously described.
  • the slide 23 is after that Actuation preferably by a spring, not shown withdrawn to its original position.
  • the detent switch 21 then remains in the actuated position and must, as already described, with the reset element 20 be neutralized again.
  • FIG. 11 shows a simplified version of the Attachment device.
  • Pivoting buffer 8 instead of Pivoting buffer 8 uses a rigid pivoting lever 48, which in the same way as the swivel buffer 8 from Actuator 12 is actuated via the plunger 31.
  • the Swivel lever 48 is mounted in the swivel bearing 11 and the left End of the foot part of the pivot lever 48 actuated in swung out the safety switch 13, too again in the same way as the actuating finger 30 of the Swivel buffer 8.
  • the swivel lever 48, or its Swivel bearing 11 is on the top of an example frame 46 welded together from steel plates.
  • the actuator 12 is on an inner wall of the frame 46 attached and the frame 46 itself is over a Fastening fitting 47 in this way with a guide rail connected that it held in both horizontal axes is, however, in the event of a collision with a cabin the pivot lever 48 after a certain vertical braking distance can do below.
  • the frame 46 is that this is possible placed on a normal shaft buffer 45.
  • the Manhole buffer 45 can, depending on the mass and speed of the Cabin, an energy storage or energy be consuming type.
  • A is shown as an example Energy-storing type with a dampening effect.
  • the device according to the invention works as follows: In order to be able to get into the pit 3, the cabin 1 sent to a higher floor.
  • the bottom one Landing door 17 can be unlocked and Tripping device 18, 25, 26 and the standardized
  • the triangular key can be unlocked and opened.
  • the Triangular bolt 18 or 25 is depending on the version Memory circuit openly accessible or with a Screw cover or covered with a slider 23.
  • the Actuation of the triangular pin 18 and in the execution 7-10 of the second triangular pin 25 after pushing back the slider 23 sets the Latch switch 21 in the locked position, whereby the Safety circuit of the elevator control is interrupted. Now the shaft door 17 can be opened manually and in the Open position can be locked.
  • the two are opposite arranged swivel buffer 8 by switching off the Actuator 12 automatically within the line of motion 7 and thus tilted into the range of motion of the cabin 1.
  • this Entry into shaft pit 3 will be there additionally existing control switch actuated so that a multiple interruption of the Safety circuit is present. The maintenance and Control work can now be carried out safely.
  • the device according to the invention can in principle for any funding facilities are used, which at Maintenance rooms limited in depth or height at the end points endangered.
