Definitions
- the invention relates to a climbing aid to support a Person in overcoming height differences, in particular when climbing buildings such as chimneys, lattice masts or Wind turbines above ladders, stairs or the like, comprising a fall protection device, a stationary Constant tension winch with a drive motor and one of the Constant tension winch driven pull element for applying a essentially constant pulling force in an upward direction pointing towards the person to be supported, the Traction is less than one against the Force acting direction of the tension element Weight force component of the person.
- a device for automatic securing of a climber on a climbing wall known that a fall protection device and a Sink prevention device Safety rope of the fall protection device comprises, wherein this latter device either from a counterweight or a fixed, motor-driven constant tension winch is formed, which has a small upward pulling force exerts the pull rope and thus on the climber.
- the device cannot be used as a climbing aid, since it does not allow reversal of movement on the ladder because the Fall protection device a movement of the pull rope in Descent direction blocked. When used as a climbing aid this blockage could only be removed by that the climber jumps off the ladder, otherwise it the fall protection device would not succeed trigger the pulling force of the winch. It also prevents Fall protection device also lowering the pull rope for another climber.
- a similar climbing aid is also known from US-A-4,252,214 known in which the pulley with the pull rope connected counterweight is designed as a piston, which is in a vertical cylinder filled with liquid up and down moved, also here when descending on the ladder from the person descending has a pulling force on the counterweight must be applied to this in the piston upwards pull.
- WO 99/24122 From WO 99/24122 is a climbing aid with a known motorized winches, as well as those on a rope hanging person is carried by the rope and the one above fall protection device engaging the winch on the rope includes.
- this climbing aid does not allow you to get off on Rope without disengaging the fall protection device.
- the rope above the fall protection device also a crash is inevitable.
- Fall protection devices with a along a guide sliding slides are basically known per se just like constant tension winches with a drive motor and one Rope drum, where the from a rope drum to a Pull rope of the winch exerted a predetermined value having.
- Such constant tension winches are used, among other things, as Mooring winches for the mooring lines of ships in ports used where the pull rope is hauled in when rising Water level from the respective ship to the free end of the The pulling force exerted decreases to drift off prevent, and where the pull rope is omitted if at sinking water level from the respective ship to the free one End of the pull rope exerted greater force to hang to prevent the quay wall.
- the invention is based on the object a climbing aid of the type mentioned at the beginning improve that supported person at every point stop and continue to climb up or down, that the climbing aid when descending is not a burden for the descending person, and that the free end of the Traction element easier to the lower end of the ladders, stairs or the like can be moved back to the other people Ascent and, if necessary, a joint stay at the upper end the ladders, stairs or the like.
- the Climbing aid separate devices for Interruption of the energy supply to the drive motor or the Power transmission from the drive motor to the tension element includes which is essentially from any point of the ladder, stairs or The same can be operated, and that the Fall protection device comprises a sled that slidable along a guide separate from the tension element is.
- the drive motor is preferably an electric motor, the Circuit can be closed and interrupted to the Switch the electric motor on or off if that Tension element when climbing the ladder with the constant Tractive force applied or when descending from the ladder should be relieved.
- an electric motor are basically other drive motors can be used, for example internal combustion engines, their ignition can be turned off or turned on as needed Hydraulic motors, the pumping rate of which can be changed as required can, or any other motor that interrupts the Allow energy or power transmission, such as for example Stirling or air engines or spring engines.
- a drum or other Device for winding the tension element which preferably is formed by a rope, but also in the form of a chain or a belt or strap or other flexible Tractive force transmission element may be present, which includes Constant tension winch torque control devices for generation an essentially constant drum torque and thus a substantially constant force in the tension element, which leads to Example one between the drive motor and the drum arranged turbo clutch, slip clutch, induction clutch or may include permanent magnet coupling or at Use of an electric motor or internal combustion engine in the form an electronic control device or when using Hydraulic motors are in the form of a proportional control can, but are not limited to.
- a so-called rotating field magnet is preferred as the drive motor used, i.e. a short-circuit proof three-phase asynchronous motor, the one at a standstill with full mains voltage can be switched on and then a constant torque holds that at low speeds, as by the low ascent speeds when climbing a ladder caused on the drum, not significant changed and thereby in the context of the present invention as is called constant.
- Torque control devices can control the torque of the drum and thus that from the tension element to an ascending person applied traction to a constant fixed value can be set that is less than the weight of one individual person or the smallest weight of a group by persons whose use of the climbing aid is intended and with a weight of the person between 700 and 900 N for example, can be 500 N.
- the Traction is adjustable according to need, for example by regulating the voltage applied to an electric motor or the distance between two clutch plates Magnetic coupling.
- Cord switch can be used, for example with the Circuit of an electric motor used as a drive motor interrupt or close or the ignition of an as Turn off the internal combustion engine used or can be switched on.
- a Remote control can be used, for example, a switch in the circuit of the electric motor or an actuator Torque control device to adjust.
- the constant tension winch can be at the top of the ladders, stairs or the like can be arranged, for example, at Ladders or stairs in shafts or wells are preferred, where the top of the ladder is at ground level.
- the constant draft winch is preferably located at the bottom of the ladders or stairs, being their pulling element is deflected via a deflection device at its upper end.
- a deflector at the top of the
- the constant draft winch can be used on ladders or stairs can also be arranged in between at any level.
- the tension element in the Freewheel from the constant draft winch drum if the energy supply to the drive motor or the power transmission to the tension element is interrupted. That way it can Traction element with a relatively low force from the Drum are withdrawn, this force either without further by those on the ladders, stairs or the like descending person can be applied to their Seat belt or harness the free end of the Traction element is attached, or by one at the free end of the Return weight attached to the tension element, its weight the free end of the tension element, for example, after one Interruption of the energy supply to the drive motor of the Constant tension winch and after loosening the seat belt or Harness to the bottom of the ladder or stairs pulls down.
- the climbing aid can not only be used as support for people used to overcome height differences, but also in addition to the material transport by the free End of the tension element with a material transport container or the like is connected by a guide along the Ladders, stairs or the like can be moved.
- This guide can be, for example, a tensioned rope be formed, or alternatively for ladders, for example by a ladder bar or one parallel to the ladder bars Rail on which the transport container can be moved.
- the tour can also be part of one Form safety device according to applicable Safety regulations on higher ladders or stairs must exist to prevent people from crashing prevent this from stopping on the ladder or stairs to lose.
- These known safety devices usually consist of one along the tour sliding safety carriage, which in the event of a crash blocked and prevented a free fall of the person.
- the safety carriage 8 comprises a locking lever 11 which is pivotable in the carriage 8 is mounted on a safety rope 12 with a seat belt 14 a harness 16 is connected and a positive or frictional holding engagement of the carriage 8 with the Tragholm 4 causes when he falls after the person 10 is pivoted below.
- the harness 16, the one in front Ascent via ladder 2 by ascending person 10 must be created, one known to those skilled in the art Construction and functioning on and should therefore not be closer to be discribed.
- the climbing aid essentially consists of a so-called Constant tension winch 18, which in the illustrated Embodiment near the lower end of the conductor 2 mounted on the bottom of the rotor mast of the wind turbine is, as well as a pull rope 20, which has a at the top of the Head 2 mounted pulley 22 is guided, being one End on a cable drum 24 of the constant tension winch 18 is wound up and its other free end with that Belt harness 16 is connectable, so that with the help of the pull rope 20 an upward pulling force on the harness 16 and thus on a person climbing up the ladder 2 10 can be exercised to give this person 10 the ascent facilitate.
- Constant tension winch 18 which in the illustrated Embodiment near the lower end of the conductor 2 mounted on the bottom of the rotor mast of the wind turbine is, as well as a pull rope 20, which has a at the top of the Head 2 mounted pulley 22 is guided, being one End on a cable drum 24 of the constant tension winch 18 is wound up and its other free end with that Belt harness 16 is
- the free end of the pull rope 20 can be, for example, by means of a Snap hook or the like directly with the harness 16 are connected, however, applies to the illustrated Embodiment on one above the safety carriage 8 on the support bar 4 of the ladder 2 slidable Return carriage 26 on.
- This can with a tether 28 the harness 16 are connected, preferably in Chest area so that the person 10 from the harness 16 in is held in an upright position when climbing the Head 2 slips and hangs on the tether 28.
- an electric drive motor 30 comprises the rotary drive for the cable drum 24
- the clutch 34 is set so that the cable drum 24 at switched on drive motor 30 of this with an im Substantially constant torque is applied.
- This Torque corresponds to a pulling force in the pull rope 20, which is smaller is as the own weight of the respective, on the ladder 2 after rising person 10.
- Rotating field magnet i.e. on short-circuit proof three-phase asynchronous motor
- constant standstill torque by changing the applied voltage can be adjusted.
- Rotating field magnets are for example from Georgii Kobold, August Heine GmbH & Co., Leinfelden-Echterdingen, Germany, available.
- a torque is preferably set which is one Tractive force in the pull rope 20 corresponds to about 500 N, so that when Use the climbing aid on ladder 2 upwards rising person 10 during their ascent with this traction is pulled upwards and thus with a body weight of 750 N the required to climb ladder 2 Energy expenditure is reduced to about a third. If the Ascent ended or should be canceled, for example to descend on ladder 2, the Traction in the pull rope 20 from that standing on the ladder 2 Person be relieved by the energy supply to the Drive motor 30 or the power transmission from the drive motor 30 to the cable drum 24 is interrupted.
- this is in one Feed circuit of the drive motor 30 two cord switches 40, 42 are provided, each by means of a fixed ladder 2 parallel pull cord 44, 46 left and right of the ladder 2 be operated.
- the two pull cords 44, 46 are in annular guides (not shown) along the conductor 2 led upwards and are near the top of the ladder 2 connected by a two-armed rocker arm 48, which in its Center is articulated to the ladder bar 4.
- the left pull cord 44 is pulled up and the left cord switch 40 actuated when one is acting downward Traction is applied to the right pull cord 46, and conversely the right pull cord 46 pulled up and the right cord switch 42 operated when one is down acting tensile force is applied to the left pull cord 44.
- the dead weight of the return carriage 26 is chosen so that it is greater than the sum of the Dead weight of the pull rope 20 between rope drum 24 and Deflection roller 22 and the frictional resistance of the cable drum 24 the constant draft winch 18 switched off. This means that the return carriage 28 after the drive motor 30 is switched off the winch 18 automatically along the support beam 4 down moves when it is released from the harness 16 at the top End of the support beam 4 of the conductor 2 is released.
- the dead weight of the return slide 26 of 50 N is included usually sufficient.
- the return slide 26 can be provided by reversing the direction of rotation of the constant tension winch 18 again to go down, reducing its own weight can be.
- Reversing the direction of rotation of the constant draft winch 18 is also advantageously carried out by operating the pull cords 44, 46, but in this case the circuit in both Cord switches 40, 42 by a first pull on the associated pull cord closed and by another train is interrupted again.
- the two cord switches 40, 42 carry current with reversed polarity to the drive motor 30 of the constant tension winch 18 so that the one for entering or Switching off the upward movement and the other one for switching on or switching off the downward movement is used.
- articulated attached two-armed rocker arm 48 can also be a fixed Bracket for the upper ends of the pull cords 44, 46 is provided be in this case by one or two times Pull up.
- a rotating field magnet As a constant tension winch in addition, two different voltages are provided to apply to the rotating field magnet, namely a higher voltage, which has a standstill torque corresponding to a pulling force of generated about 500 N, and a lower voltage, the one Standstill torque corresponding to a tensile force of approx. 50 N generated so that the constant tension winch 18 and Return carriage 26 exerted tractive forces approximately the scale hold.
- This lower voltage is controlled by a main switch (not shown) turned on and is due to the rotating field magnet on when the higher voltage with one of the cord switches has been switched off.
- Proportional control or the like can also be used be provided with which at least one of the Rotating field magnet applied voltages can change, so the torque of the constant tension winch 18 and thus the pulling force in the pull rope 20 to the weight of an ascending person 10, the Return carriage 26 or one at the end of the pull rope 20 or at Return carriage 26 to adjust attached load.
- the free to connect to the harness 16 needs End of the pull rope 20 not by hand as in the prior art be pulled down to the rise of another To facilitate person 10 with the climbing aid 2. Instead can the return slide 26 after loosening the tether 28th simply by switching off the drive motor 30 or reversing from the direction of rotation to the lower end of the head 2 moves where the harness 16 of another person 10 connected to the carriage 26 for a new ascent can be.
- the support beam 4 serving as a guide for the return slide 26 is at its upper and lower ends with a mechanical Provide a lock that prevents the return carriage 26 leaves his leadership.
- the return carriage 26 itself is further designed so that a tool container (not shown) can be attached, its own weight including the weight of its content and the weight of the Return carriage 26 under the set tractive force in Traction rope of 500 N lies so that the tool container through Switching on the drive motor 30 are pulled upwards can.
- These guides are preferably in the form of eye bolts, welding or Castings (not shown) formed to the rear and protruding laterally at regular intervals on the ladder rail 4 are attached and one eye for the passage of the Have pull rope 20 and the pull cords 44, 46.
