Definitions

  • the present invention relates to a fall protection device for lifting doors, hatches, lattice doors and such commercial doors with vertical or partially vertical opening and closing movements.
  • a fall protection device for lifting doors, hatches, lattice doors and such commercial doors with vertical or partially vertical opening and closing movements.
  • an accessory of the suspension device such as a wire rope, a compensating spring, chain and the like
  • a door which is pulled up can fall, which can result in a serious accident.
  • the legal safety regulations in accordance with the trade regulations, building laws, occupational safety and traffic jam laws can be met by attaching systems that cause the same to fall if the cable is clamped or damaged, the spring cable breaks, the cable on which the door is suspended, etc. prevent.
  • the present invention aims to provide suitable protection against such accidents.
  • At least two separate steel cables or chains must be used to suspend vertically opening and closing doors.
  • the cables are made of retracted galvanized wire ropes and they are constructed as prescribed in the standard NEN 3231: "Steel cables, parallel constructions for lifting and pulling devices”.
  • the fall arrest device as mentioned at the outset is characterized according to the invention by housings which are fastened on one side or on both sides of the door opening, depending on the weight of the door, on the upper side of vertical guide rails on the wall or the portal construction, and in which one is mounted axle, on which a drum is welded, on the contour surface of which a securing tape is wound, and on which a locking wheel is also welded, which is connected to a self-winding flat coil spring, which exerts a force which keeps the securing tape wound while in secant shape attached recesses in the outline of this locking wheel fits a pawl from a lock holder which blocks the rotation of the axle in one direction when the pawl engages in one of the recesses in the secant direction.
  • this button is provided with an electrical switch which allows the current to pass through in a neutral state.
  • the power supply is interrupted by the action of these buttons as a result of slackening or tearing of the cables.
  • a tilting mechanism is mounted on each spring that is used, which is tilted by the force developed by the spring during the winding process. In the tilted state, an electrical switch is operated which allows the current to pass through.
  • the spring tears or loosens the spring will be in a neutral position, eliminating the force that should keep the tilt mechanism in a tilted position.
  • an electromagnet is located above the ratchet wheel in the above-mentioned housings, which holds the pawl up.
  • the blocking for securing when the cable breaks can therefore be caused, as described, by the mechanical pushbutton device (rod with fork) towards the pawl or by an electromagnet mounted above the pawl, which no longer exerts its force when a circuit flows through a cable switch , is interrupted.
  • the ratchet wheel is centrally connected to the axle as it is to the drum on which the securing tape is wound.
  • the end of the security band running out of the housing is connected to the door.
  • the securing band When moving upwards, the securing band is wound onto the drum as a result of the self-winding flat spiral spring, which acts on the locking wheel, which is welded onto the mounted axle.
  • reliable checking of the correct functioning of the safety device is possible manually by interrupting the circuit, which corresponds to the situation which occurs in the case of cables which are not tightly tensioned, in the event of cable breaks, spring breakage or slack springs.
  • the security band is attached to the underside of the door.
  • a pawl (6) which is held up by an electromagnet (10) or a rod (8).
  • the pawl is fastened with a hinge joint in the pawl holder (9).
  • the electromagnet (10) is fed from a transformer 220/24 V (18).
  • a cable button (11) is attached behind each lifting cable (14).
  • this button actuates an electrical switch (15) which allows the current to pass through.
  • Each torsion spring (7) attached in front of the door is coupled to a tilting mechanism (12).
  • this mechanism When the spring is normally tensioned, this mechanism is tilted due to the torsional force of the spring and becomes the electric one Switch (16) actuated, which passes current in this position. If the electrical components are connected in series (Fig. 3), the electromagnet is actuated. If the resilient pusher (13) is now pressed, the pawl on the electromagnet is lifted and held in this position.
  • the mechanism continues to return to the neutral position through the attached tension spring, as a result of which the electrical switch (16) no longer allows current to pass.
  • the electromagnet (10) is no longer supplied with current and the pawl (6) can no longer be held up. Due to its own weight and the attached tension spring, the pawl quickly falls down and engages in one of the recesses
  • the door If the door is blocked by the lock, it can only be opened further by lifting it with a forklift, for example.
  • the self-winding drum (2) By engaging the pawl (6), the self-winding drum (2) can only turn to the left, which means that the door can only be moved upwards.
  • the pawl immediately engages in the recess, which immediately brings the door back into the safe position.
  • a blocked door can only be closed by lifting the door slightly and then pressing and holding the resilient handle (13) until the forklift has lowered the door completely.
  • the handle (13) is released, the pawl (6) immediately engages in the recess and the door is immediately brought to a safe standstill.
  • the drum with the belt can only turn when the lifting cables and springs are taut and the circuit is closed.
  • a lifting door with a height of about 6 m.
  • a weight of 800 kg is secured by a device according to the invention, which consists of two housings according to the accompanying figures, with the interacting parts shown therein, a flat spiral spring which engages the locking wheel from a length of about 12 m in a stretched state Stainless steel band.
  • Other dimensions are of course possible.
  • the weight of the door can be increased to 400 kg.
  • the shear stress in the recess of the ratchet wheel then becomes 2
  • the securing band has a tensile strength of 1571 kg. With a safety factor of 3.9, the permissible load is 400 kg.
  • the electrical installation is carried out in accordance with the requirements of NEN 1010.
  • the switch is a closed contactor, which has a mechanically forced interruption switching function, as specified in VDE 0660, T 206 and VDE 0113, I.E.C. 44.
  • the magnetic core is provided with a copper layer.
  • the device described is approved for this purpose by
