Definitions
- the invention relates to a fall protection for a roller shutter or the like for attacking a motor-driven winding shaft for the roller shutter with a worm wheel arranged on the winding shaft in a rotationally fixed manner and a worm meshing therewith, which is displaceably mounted in the axial direction and axially due to an error-related increase in the speed of the worm wheel is movable against a stop, so that the dynamic self-locking between the worm and the worm wheel brakes the winding shaft.
- a known fall arrest device of this type AT-B-330.429 - its axially displaceably mounted worm gear is connected on the one hand via a worm wheel meshing with it to the winding shaft of a roller shutter armature and on the other hand via a spur gear pair to a drive motor unit which drives a worm gear, which in turn is connected to the winding shaft via a worm wheel meshing with it.
- the winding shaft tries to rotate under the load of the roller shutter curtain in the sense of a fall movement beyond the operating speed and exerts a force on the worm of the fall arrest device via the assigned worm wheel in the direction of its axial displacement without turning the screw because of the self-locking intervention.
- the coupling of the worm to the drive motor unit is interrupted, which is done either by axially shifting the gears of the spur gear pair until they are disengaged, or by destroying a predetermined breaking point in the area formed by the spur gear pair Coupling between the worm and the drive motor unit.
- the axial displacement path of the screw increases up to the stop and thus the fall path of the falling roller shutter curtain, in the latter case there is a correspondingly higher restoration effort.
- the invention has for its object to provide a crash device of the type mentioned, which works quickly and safely, is simple and can also be retrofitted to existing roller doors.
- this object is achieved according to the invention in that the worm is pushed by a servomotor at its nominal speed in the direction of its axis onto the stop and is driven in a controlled manner in adaptation to the rotary movement of the winding shaft in normal operation.
- the assigned worm wheel which is arranged on the winding shaft in a rotationally fixed manner, engages - dynamically self-locking - is driven by a servomotor via a control so that the rotation of the worm wheel does not move the worm or its axis or in one direction just moved to the stop and stops there.
- a nominal speed of the servomotor is assumed, which can only be slightly greater than that which is required in order to maintain the relative position of the screw or its axis at the stop in normal operation. If this happens, the gate will crash faster rotating worm wheel, the worm or its axis is firmly pressed in the direction of the stop and braked there in this position.
- the winding shaft 5 is shown in section transverse to its axis.
- a worm wheel designated overall by 7 is attached in a rotationally fixed manner.
- This worm wheel 7 meshes with a worm 8, a dynamic self-locking being present between these parts.
- the axis 9 of the screw 8 is guided by means of two bearings 10, 11, for example conventional plain bearings, against tilting or other movements as displacements along the axis 9 in device and / or gate-fixed receiving parts 12, 13.
- the axis 9 of the screw 8 can be moved in the direction of the arrow 14 towards a stop 15 fixed to the housing. Furthermore, for damping purposes, a damping body 16, for example foam aluminum, can also be attached to the stop 15 or, as shown, to the free end of the axis 9 of the screw 8.
- the worm 8 is driven in a controlled manner by a servomotor 17 and by means of a controller designated overall by 18.
- the axis 9 of the screw 8 has a collar 19, in the region of whose two ends two on-off switches 20, 21 are arranged, which are connected to the controller 18.
- This controls the servomotor 17 via the output line 22 so that - in normal operation of the roller door - the axis 9 of the screw 8 does not reach the stop 15. Only in the event of a crash, when the limited maximum speed of the servomotor 17 is not sufficient to carry out regulation, does the axis 9 come to rest against the stop 15, as a result of which the crashing gate is braked and held in this braked position.
