Definitions

  • the invention relates to a device for erecting and aligning a tiltable telescopic mast mounted on a transport vehicle, which can be moved from a horizontal or almost horizontal transport position in a vertical plane by means of one or more lifting cylinders
  • DE 31 05 621 C2 describes a device for erecting and aligning a vehicle mounted on a transport vehicle.
  • a lifting device which likewise comprises a tiltable telescopic mast mounted on a transport vehicle, the transport vehicle being supported on the ground by means of support arms
  • the object of the present invention is a device of the aforementioned type, which makes it possible to mount a tiltable telescopic telescope mounted on a transport vehicle.
  • masts can be erected and aligned in a simple manner in the vertical direction with a short expenditure of time, small bending moments being exerted on these mechanical parts due to the short movements of the individual parts, and the process of erecting and aligning is easy.
  • the device described above is used, which is characterized in that it comprises: a) a support frame for the telescopic mast, which is connected to the vehicle frame via three lifting elements height adjustable, b) four, pivoted and mounted on the support frame lowerable outrigger, which can be swung out and lowered by operating only one pulling device.
  • each support arm is connected to the support frame via an overhead gimbal bearing and an underlying guide pin that slides in a link guide of the support frame.
  • the pulling device which causes both the pivoting out and the lowering of each support boom, is a spindle drive. This enables a safe, play-free and exact lowering of the jib.
  • the lower end of the support arm facing the support frame, on which the pulling device engages can be drawn into a guide located underneath, which is located in the support frame. It is hereby achieved that after the lowering of the support arms, which bring about the support of the extended telescopic mast, a mechanically very stable system is formed.
  • the three lifting elements which are attached between the support frame for the telescopic mast and the vehicle frame are and cause the height adjustment between this Surah ⁇ men and this vehicle frame, dimensioned so that after setting up and aligning the telescopic mast, the transport vehicle can be lifted from the ground by suitable actuation of the lifting elements.
  • the telescopic mast only has contact with the ground and the transport vehicle lifted off the ground via the four support booms, advantageously with the interposition of floor panels, which now has its vehicle frame and the threaded spindles on the carrier frame of the telescopic mast hangs, represents a ballast, which contributes to the further stabilization of the telescopic mast.
  • the lifting elements and / or the lifting cylinder are formed by threaded spindles or by hydraulic drives or hydraulic motors.
  • Telescopic masts can have a considerable height of e.g. have up to 45.
  • Such mobile telescopic masts can e.g. can be used as antenna masts for directional antennas, in particular parabolic antennas.
  • the carrier frame represents the central unit of the antenna carrier, to which all elements to be moved are coupled.
  • All the forces acting on the telescopic mast are absorbed and transferred via the articulated support brackets.
  • Two torsionally rigid bearing blocks for a pivot bearing are provided on the support frame in a manner known per se, around which the telescopic mast attached to it is transported horizontally or almost horizontally ⁇ position can be erected in the vertical position. This is achieved by means of the lifting cylinder or cylinders in a manner known per se.
  • the carrier frame is connected to the vehicle frame via lifting elements. Since the transprot vehicle is usually practical in the longitudinal and transverse directions at the installation site of the mast.
  • the carrier frame is first aligned as horizontally as possible, in particular in the plane transverse to the longitudinal axis of the transport vehicle, by actuating the three lifting elements which are attached between the carrier frame and the vehicle frame. Alignment in the longitudinal axis of the transport vehicle can take place at the same time as far as the movement of the lifting elements allows.
  • the lifting devices are then still a corresponding length, z. B. 20 cm, extended further, d. H. the distance between the carrier frame and the vehicle frame is increased by this 20 cm while maintaining the previously set distances.
  • the four outrigger arms are then pivoted out and lowered one after the other, advantageously one after the other.
  • the support brackets are mounted on the support frame so that when the pulling device is actuated they first swing out of their transport position against the vehicle and are then lowered. This lowering takes place only until each support arm has contact with the ground, this contact advantageously taking place via base plates for better weight distribution and the support arms engage with their outer end designed as a ball in the ball socket of the base plate. Subsequently, by actuating the lifting cylinder or cylinders, the telescopic mast still in the transport position is erected vertically in the swivel bearing, with the mast being aligned exactly vertically here.
  • the telescopic mast was aligned vertically in this way both in the vertical plane parallel and transversely to the longitudinal axis of the transport vehicle, and this orientation is not changed by the individually lowering of the four support brackets to the ground, so the vertical one remains Get alignment of the telescopic mast.
  • the telescopic mast is then only expediently extended, i.e. brought to its full length.
  • FIG. 1 is a side view of a transport vehicle with a telescopic mast in the transport position
  • 2 shows a side view of the transport vehicle with the telescopic mast erected and the jibs swung out and lowered
  • FIG. 3 shows a detailed illustration of the bearing ends of a jib
  • 4 shows a plan view of the support frame with the bearing points for the support arm and the guides for the lower end of the support arm;
  • Fig. 5 is a side view of the support frame.
  • the transport vehicle is designated 11 in FIG. 1.
  • the transport vehicle has a vehicle frame 3, on which the threaded spindle 4 'is integrated at the rear end of the vehicle and two threaded spindles 4 are integrated into the support frame 1 behind the driver's cab, which is formed by a lattice work, as better shown in FIG 5 can be seen.
  • the threaded spindles are supported on the vehicle frame 3 downwards.
  • two support arms 5 are shown on the front side of the vehicle, which bear against the transport vehicle 11 in the transport position.
  • the support arms are articulated at the top and bottom of the support frame 1.
  • Two bearing blocks 13 are attached to the support frame, only the front bearing block being visible.
  • a pivot bearing 14 is located on this bearing block, around which the telescopic mast 2 can be erected when the lifting cylinder 15 is actuated, as shown in FIG. 2.
  • the support frame 1 has already been lifted a short distance from the vehicle frame 3 by actuating the threaded spindles 4 and 41 and is oriented so that the erected, retracted telescopic mast is set up as vertically as possible.
  • the support arms 5 have already been swung out and lowered, whereby they have contact with the floor via the floor plates 16.
  • the spherical ends 17 of the support arms which are shown in FIG. 3, engage in these base plates 16.
  • the telescopic mast can be extended and, if desired, the transport vehicle
  • FIG. 3 shows the end of a support arm that can be articulated on the support frame, 7 ′ representing the upper bearing point.
  • This upper bearing is a cardanic bearing, so that a lowering of the support arm after pivoting out of the transport position is possible.
  • a pulling device advantageously a spindle drive, engages at the lower bearing point 12 of the support arm 5, which causes both the pivoting out of the support arm and its lowering.
  • FIG. 4 Such a pulling device is schematically designated 6 in FIG. 4.
  • 9 denotes the lower guide pin, which engages in the link guide 8 shown at the top right in FIG. 4.
  • the upper pivot point 7 and the guide pin 9 are not perpendicular to one another, so that when the pulling device 6 is actuated and the guide pin 9 is thus moved in the link guide 8, both the pivoting and lowering of the support arm S is brought about.
  • the cross-shaped lateral guides 10 for the lower end of the outrigger 5 are also shown.
  • FIG. 5 shows a side view of the support frame 1 from FIG. 4, from which the arrangement of the threaded spindles 4 and 4 'and the articulation points of the support arms 5 at 7 and 8 are evident, as well as a bearing block 13 with the pivot bearing 14.
  • the pulling device 6 is advantageously also a threaded spindle, the pulling rod engaging by means of a ball 18 in the lower bearing point 12 of the jib - see FIG. 3.
