Definitions

  • the invention relates to a weight compensation device for a lifting door, in particular for a high-speed industrial door, with a spring element, a tension element and a winding device, wherein one end of the spring element is fixable on the bottom side, wherein the tension element with one end on the spring element and with the other end on the winding device is fastened, wherein the winding device can be coupled to a drive of the lifting gate, and wherein the tension element on the winding device such up or unwound that the spring element has its greatest bias when a door leaf of the lifting gate is in the closed position, and substantially is relieved when the door leaf is in the open position.
  • the biasing force of the spring element is chosen so that it exceeds the respective weight of the free Torblattin, so not moved out of the door opening Torblattabitess up to a desired balancing point in each case.
  • this compensation point is typically at a gate opening height of 2.5 m.
  • the door leaf moves automatically to an open position with a Clearance height of 2.5 m, if due to a defect in the drive mechanism or by a manual unlocking, for example in the case of a power failure no locking effect by the drive is given more.
  • torsion springs for weight compensation. These are arranged coaxially to a drive shaft and fully tensioned in the closed position of the door leaf and correspondingly relaxed when the door leaf is open.
  • torsion springs are subject to increased wear, which is why their life is limited.
  • torsion springs suffer due to the jerky movements significant dynamic voltage spikes.
  • weight compensation devices of a type have prevailed, as for example in the WO 91/18178 is explained.
  • These have a spring element, typically a coil spring, as well as a tension element attached thereto usually in the shape of a band.
  • the lower end of the spring element is fixedly connected to the ground, while the upper end is coupled by the tension element with a winding shaft arranged on the side of the hoistway winding shaft.
  • the tension element is wound in the course of the closing operation of the lifting gate on this winding shaft with directly superimposed layers, so that the spring element increasingly tensioned.
  • the opening movement of the door leaf is connected to a unwinding of the tension element of the winding shaft, so that in this case results in a relaxation of the spring element.
  • the winding shaft is coupled to the drive of the lifting gate.
  • the invention is therefore based on the object, a generic weight balancing device in such a way that with little design effort required for an effective weight compensation torques can be provided and also an increased life is achieved.
  • a weight compensation device having the features of claim 1. This is characterized in particular by the fact that the tension element at the end facing the winding device has a smaller width than at the end facing the spring element, and that the winding device has a shaft and a guide device mounted thereon, by means of which the tension element can be wound in such a way that the winding layers are contactless to each other, wherein the guide device for this purpose has circumferentially guide surfaces with a continuously growing in the winding direction radius.
  • the weight compensation device according to the invention can thus be used advantageously even for very large and heavy gates.
  • the configuration according to the invention has the advantage that the choice of the effective radius, or the effective lever length on the guide device is ausgestaltbar regardless of the thickness of the tension element, since this only appropriately designed guide surfaces must be formed on the guide means.
  • This allows a professional alone by targeted shaping of the guide means make an individual adjustment of the weight balance to the respective dimension of the Hubtorblatts and its weight, without having to take this example, for example, on the thickness of the tension element, the core diameter of a winding shaft consideration.
  • Another advantage of the weight balancing device according to the invention is that the tension element can be wound free of axial displacements due to its special design. This makes it possible to avoid one-sided loads on the tension element and the wear of this thoroughly stressed in use element can thus be kept low. This has an advantageous effect on the life of the weight compensation device according to the invention.
  • the width of the tension element may increase stepwise from the end facing the winding device to the end facing the spring element, wherein the guide means comprises at least two guide portions which are each formed so spirally and axially offset from each other, that at an inner guide portion an outer pair of guide section connects, the minimum guide surface radius of the maximum guide surface radius of the inner guide portion corresponds.
  • the width of the tension member steadily increases from the end facing the winding device to the end facing the spring element, and that the guide means comprises two guide spirals extending axially from one central portion with increasing radius away from each other extend outside.
  • This also makes a non-contact winding of the tension element possible, but a three-dimensional configuration of the guide surfaces is required.
  • this configuration also makes it possible to provide the guide surfaces provided according to the invention with a radius which increases continuously in the winding direction.
  • the tension member is a chain
  • the tension member can be a stable, yet very flexible in the winding direction configuration of this component of the To provide weight compensation device according to the invention.
  • such a chain has a very high tensile strength, which is why it can be used particularly advantageously on lifting gates with large dimensions of, for example, 8 m width and 6 m height.
  • the tension element is formed as a band.
  • This configuration is particularly advantageous if the width of the tension element increases steadily from the end facing the winding device to the end facing the spring element, since such a design mode with a belt manufacturing technology is easier to implement than with a chain.
  • a material for such a band are, for example, metal or plastic and in particular fiber-reinforced plastics into consideration.
  • the spring element has at least one helical spring.
  • coil springs have already proven themselves in practice in known weight compensation devices many times because of their robustness and reliability.
  • with such coil springs can easily provide the desired spring properties.
  • a lifting gate is provided according to claim 7, which has a door opening covering Torblatt, which is movable by a drive from an open position to a closed position and vice versa, said lifting gate is equipped with a weight compensation device according to the invention.
  • This lifting door thus advantageously takes advantage of the advantageous properties of the weight compensation device according to the invention, so that it has a relatively small number of components and is particularly robust, low-wear and durable.

  • the movement of the door leaf 2 between its end positions is effected by a drive 5.
  • This has a motor 51, here an angle motor, which is received in the region of a side frame in the lintel area and coupled there directly to a drive shaft 52.
  • the drive shaft 52 passes through the spiral section 32 or 42 of the guides 3 and 4 in a central region.
