Definitions
- the invention relates to a counterbalancing device for driving a lifting gate, for position-dependent compensation of the weight of a door leaf of the lifting gate, with a power transmission unit which can be coupled to perform a door leaf lifting the opening movement and the door leaf lowering closing movement on the drive.
- the door leaf is constructed from one or more segments, wherein the respective segment can be flexible or rigid.
- Lifting gates and integrated weight compensation devices are known from the prior art.
- DE 40 15 214 A1 discloses a lifting door with a lamellar armor with bendable lamellae.
- the lifting gate disclosed therein comprises two guideways arranged on the two opposite sides of the door opening and a louvered armor with lamellae spaced apart on hinge bands such that the hinge lugs engage within a space between the adjacent louvers. It is further disclosed that this lifting gate is designed as an industrial lifting gate in the sense of a high-speed door. Such lifting gates are designed as rolling doors that close or release the walk-through or passable door openings.
- tension springs for compensating the weight of the individual slats, which form the door leaf, are used.
- tension springs have the disadvantage that they only have a lifetime of about 200,000 strokes.
- torsion springs have an even shorter life, from about 30,000 to 40,000 strokes.
- tension springs commonly used also have a further disadvantage, namely that they require a lot of space in heavy gates, which must be available in particular on the sides of the door opening. Is a frame of the door not wide enough to accommodate juxtaposed tension springs, of which the necessary Although there is still the possibility of arranging them in succession, both types impair the efficient use of space in the area of a lifting gate.
- Alternative weight compensation devices are known from the prior art, which are used for example in sectional doors.
- DE 102 32 577 A1 discloses a weight compensation device for a sectional door with a rotatably mounted shaft, a cable drum at least one end of the shaft on which a connected to the door leaf of the sectional door pull cable is wound, and at least one torsion spring designed as a helical spring.
- the coil spring is held at a spring end to a stationary receiving part and at the other end of the spring to a receiving body fixed to the shaft and acts as a torsion spring having a particularly short life.
- This object of the invention is achieved in that at least one compression spring is provided, which is arranged so that it supports the opening movement.
- Such compression springs can endure a higher load over many years compared to tension and especially torsion springs, without a failure occurring after a relatively short operating time or maintenance work having to be carried out at an early stage. Tests carried out on certain compression springs have shown that no significant spring deformations have occurred after one million strokes.
- a solution according to the invention is therefore not only inexpensive and durable, but also allows the advantage of a particularly simple and efficient construction.
- Advantageous embodiments are claimed in the subclaims and are explained in more detail below.
- the motion converting device therefore utilizes the force storable in a compression spring to transmit a assisting torque to the transmission.
- the compression spring is arranged substantially horizontally, preferably transversely to the lifting or lowering direction of the door leaf. As a result, a good space utilization can be achieved.
- the weight compensation device can be realized in a particularly compact manner when the door leaf wound up in the raised state surrounds a cavity in which the pressure spring and / or the movement-changing device is arranged.
- the compression spring can be arranged in a hollow cylindrical guide element, wherein the hollow cylinder-shaped guide element for supporting a rotational movement of the power transmission device is mounted rotatably or non-rotatably on a frame. This allows an efficient use of spring force in a compact design.
- the guide element forms a non-rotatable hollow cylinder or the guide element forms the drive shaft configured as a hollow shaft.
- the force of the pressure spring can be used particularly efficiently as a support torque to balance the weight of the door leaf when the compression spring is supported in a force-transmitting manner on a guide element-fixed base part and an actuating element which can be displaced translationally relative to the guide element.
- An advantageous embodiment is characterized in that the drive shaft is in operative relationship with the actuating element, which is displaceable by the compression spring in a longitudinal direction of the drive shaft.
- a gear-like training can be achieved when the actuator is torque-transmitting coupled to the drive shaft, preferably such that a movement of the actuating element along the longitudinal direction forces a torque transmission from the actuator to the drive shaft.
- the actuating element is longitudinally displaceably guided within the hollow shaft, preferably in a groove on the inside of the hollow shaft, which preferably extends substantially in the longitudinal direction.
- the groove is present on the adjusting element and corresponding counter-same projections on the inside of the hollow shaft are present.
- the adjusting element is designed as a spindle nut, it is possible to fall back on a proven conversion element. High forces can be transmitted and used over a long time resilient components.
- a further advantageous embodiment is characterized in that in the drive shaft at least one of these subdividing elastic coupling is formed.
- Such a flexible coupling in particular in the manner of a dog clutch, is advantageous in order to compensate for mechanical over-determination between lateral bearings which are used for supporting the drive shaft. It is possible to use on one side of the dog clutch only radial bearings, whereas on the other side of the dog clutch, a thrust bearing and a radial bearing are combined.
- the invention also relates to a lifting gate, in particular an industrial lifting gate, which has a door leaf, with a drive, such as a motor and a weight compensating device according to the invention explained above.
- a drive such as a motor and a weight compensating device according to the invention explained above.
- Such an engine may be, for example, an electric motor or a hydraulic or pneumatic motor. Internal combustion engines are also possible drive units.
- a viewing window is present that releases the view of the spindle nut. In this way, the adjustment of the individual elements can be controlled relative to one another.
- the viewing window extends along the longitudinal direction and is preferably aligned horizontally.
- Such a horizontal alignment is also offered by the fact that the hollow shaft, or the drive shaft, is normally arranged extending over the door opening in the horizontal direction.
- the spindle nut has an end plate for which a mounting position is marked in the viewing window, an adjustment and a mounting can be carried out easily even with untrained personnel.
- the coupling between the motor and spindle nut can be canceled by the spindle nut preferably by hand and / or using a crank in a desired mounting position can be moved, in which the coupling can be restored.
- a method is advantageous that uses the viewing window to spend after a decoupling of the corresponding elements, the end plate in the planned position and then restore the coupling.
