Definitions

  • the invention relates to a hoist for people and / or loads.
  • the object of the present invention is to provide a hoist for people and / or loads, which is structurally simple, so that not only is it easy to maintain but also provides an operating option that allows untrained personnel to steer leave or even transport loads alone.
  • the individual elements should be of conventional design, so that the hoist is composed of elements that can be quasi taken from a kit.
  • the object is achieved by a combination of features which are known in some cases and is characterized by
  • a control unit for synchronously or separately adjusting the blade angle of the rotors, the control unit starting from the housing or being integrated in the housing.
  • Coaxial rotor systems are known per se. Their construction and handling is quite complex, so that a corresponding type of drive has not or only little success.
  • a cardanic pivoting of a drive in connection with hoists such as helicopters / gyrocopters is also known.
  • a connection with coaxial rotor systems is not known in practice. However, it should offer considerable advantages over known arrangements, in particular with regard to simple maneuverability.
  • Control units for synchronously or separately adjusting the blade angles of the rotors can also be referred to as known.
  • the known here require complex components such as swash plate, intermediate storage, cyclic sheet measurement, etc.
  • the control unit is based on a so-called control stick, which is arranged in a passenger compartment and can be operated by a pilot.
  • the combination proposed according to the invention - coaxial rotor system, cardanically pivotable drive and a self-proposing control unit based on the housing accommodating the drive - represents a hoist for people and / or loads that is simple in structure, offers easy operation and maintenance friendliness that was not to be expected.
  • the known state of the art Technology no suggestion that all functionally important elements of the hoist start from a single housing, which itself is not a passenger compartment or the like.
  • the drive comprises a reduction gear operated by one or more drive units, such as a load-dividing bevel gear, between whose plate or bevel gears, the necks of which pass into the drive shafts for the rotors or represent them themselves, a transverse shaft which is rotatable about its longitudinal axis is guided by means of the at least one push rod passing through the housing and parallel to the drive shafts for the rotors is displaceable, the push rod above the housing interacting with a ring element surrounding the drive shaft of the lower rotor and axially displaceable to the latter, the position of which determines the blade angle setting, and below of the housing can be uncoupled from the control rod guided within the drive shaft for the upper rotor and determining the blade angle position.
  • drive units such as a load-dividing bevel gear
  • the cross shaft can also be located above or below the ring gear or the housing, without affecting the simplicity of the construction.
  • Two push rods are preferably arranged diametrically to the drive shafts for the rotors and have toothings which mesh with gear wheels arranged on the transverse shaft. If the cross shaft is now rotated by means of an operator or by remote control using, for example, an electric motor, the ring element is displaced by the interaction with the lifting rods, which rotates with the drive shaft for the lower rotor, so that in this way the blade angle setting in desired extent can be changed.
  • the cross shaft naturally has a self-locking feature that prevents unwanted turning.
  • a pivot lever extends from the housing, with which the housing can be pivoted gimbally with the rotors with respect to a supporting frame which comprises the passenger compartment. If loads are to be transported alone with the hoist according to the invention, the loads can be pivoted in relation to the housing by means of electrical, hydraulic or similarly actuatable actuating elements, this being possible remotely or pre-programmed.
  • the housing receiving the drive and the control unit can be designed to be displaceable and / or pivotable relative to the supporting frame in the form of, for example, the passenger compartment.
  • the housing can be connected to the cell via a tube, which in turn is rigidly connected to the cell.
  • a fork can emerge from the support frame in the form of the cell, which pivots in the housing, the fastening axis preferably running above the reduction gear. This results in an optimal weight distribution.
  • the housing can interact with a pipe running horizontally or almost horizontally to a supporting strut, which is rotatable about its longitudinal axis and has a bearing journal which penetrating from the housing and extending in this elongated hole arrangement.
  • the housing is displaceable with respect to the pin so that the pivot point of the housing can be off-center.
  • the torque resulting from this can act on a preloaded lifting cylinder which is located between the housing and the support frame.
  • the torque is determined by the position of the trunnion in the slot arrangement.
  • the resulting easy maneuverability is obvious.
  • the housing can be moved using a trim wheel.
  • the trimming / control can also be brought about by the fact that the housing is arranged centrally or eccentrically in relation to the bearing journal and the pretensioning of the lifting cylinder, which is located between the support frame and the housing, is varied.
  • the pivotability can also be achieved in that the torsionally rigid tube connected to the housing is based on a supporting strut running horizontally or almost horizontally in the supporting frame, which is rotatable about its longitudinal axis and pivotable about an axis running perpendicular to the longitudinal axis.
  • the transmission can be designed as a differential and the control of the vertical axis (course control) can also be carried out by deflecting the residual thrust of the turbine. In this way, the negative reaction to an unevenly distributed torque on the rotors in the event of control deflections can be prevented.
  • a semi-gimbal suspension of the lifting unit i.e. a degree of freedom tilting around the transverse axis
  • a cyclic blade control which would only be needed for control around the longitudinal axis, for example.
  • Fig. 1 shows a schematic illustration of a hoist in side view
  • Fig. 3 shows a hoist according to Fig. 1 and 2 for the transport of loads.
  • a lifting mechanism 10 which comprises a coaxial rotor system comprising rotors 12 and 14, a housing 16 and a support frame 19.
  • the rotors 12 and 14, which have rotor blades of the same size and in opposite directions, are actuated by a drive unit 24, for example in the form of an internal combustion engine or a turbine, via drive shafts 18 and 20, which start from a load-dividing bevel gear mechanism 22.
  • a freewheel 26 and a powershift clutch 28 can also be connected between the drive unit 24, which should be emphasized.
  • the bevel gear 22 itself comprises two bevel or ring gears 30 and 32, the necks of which pass into the drive shafts 18 and 20.
  • the drive shafts 18 and 20 are supported relative to the housing 16 by schematically illustrated bearings 72, 74 and 76.
  • the housing 16 is received in a bearing 34 in order to enable a cardanic pivoting.
  • the bearing 34 which is arranged above the housing 16, starts from the support frame 19. This provides the possibility of pivoting the housing 16 together with the drive unit 24 and the rotors 12 and 14 in relation to the support frame 19, which results in good maneuverability with a simple construction.
  • a control unit 36 is provided in or emanating from the housing 16, which enables the blades of the rotors 12 and 14 to be synchronized or decoupled - the latter for torque compensation - be adjusted.
  • the control unit 36 now has the following structure in the exemplary embodiment.
  • a cross shaft 38 which runs between the plate or bevel gears 30 and 32 of the reduction gear 22, cooperates with two push rods 40 and 42, which in turn interact via a bearing 44 with a ring or cylinder element 46, via which the blade angle adjustment of the rotor 14 he follows.
  • the ring element 46 rotates with the drive shaft 20, but is axially displaceable in relation to the push rod position.
  • the push rods 40 and 42 are arranged diametrically to one another with respect to the drive shaft axis.
  • the former In order to enable an axial displacement of the push rods 40 and 42 depending on the rotation of the cross shaft 38, the former have an external toothing 48 and 50 which mesh with gear wheels 52 and 54 which are arranged on the cross shaft 38.
  • the cross shaft 38 in turn opens into a lever 56 which can be detected in the area below the housing 16 and can be pivoted, for example, by an operator to the desired extent, in order to bring about the required blade angle adjustment.
  • the transverse shaft can also be actuated via an electric motor (not shown) or a similarly acting element, the actuation of which is optionally carried out remotely or pre-programmably. This is advantageous if the hoist 10 according to the invention is to be used, for example, only for the transport of loads or the like, without even operating personnel sitting in the hoist.
  • the push rods 40 and 42 open below the housing 16 into a cross rod 58, from which a control rod 60 extends, which extends within the drive shaft 18.
  • the blade adjustment of the rotor 12 can then - as shown - on the control rod 60 consequences .
  • intermeshing gearwheel elements which are fastened, for example, to the lower end of the push rods 40, 42, 60, to achieve a decoupled or opposite working of the push rods by rotating the push rods 40, 42, 60 by means of a Thread is converted into an axial movement.
  • a handle 62 can be actuated.
  • this decoupling can also take place via an electric motor or the like, not shown. This can also result in the possibility of automatic torque control.
  • the control according to the invention which is arranged in the housing 16 or starts from it, ensures that, with a simple construction, the blade angles of the rotors 12 and 14 are set securely without the need for structurally complex control sticks in the region of the support frame 19.
  • a lever 64 extends from the housing 16 and can have a gas lever at the lower end.
  • the throttle lever can also be arranged on the lever 56. If the lever 64 is pulled in relation to the supporting frame, moved forwards or pivoted sideways, the trajectory changes to the corresponding extent.
  • Fig. 3 The embodiment of Fig. 3 is intended to illustrate that the lifting mechanism 10 according to the invention can be used solely for the transport of loads 66 which are received by a support frame 68 which extends above the housing 16 and in relation to the latter is gimbal pivotable. Otherwise, the other elements of the hoist 10 according to FIG. 3 with those of Fig. 1 and 2 are of the same design, so that there is no need for further discussion.
  • a frame 70 extends from the housing 16 in order to enable the hoist 10 to land or take off safely.
