Definitions

  • the present invention relates to a material handling device with an articulated hose carrier and a suction hose for attachment to a suction excavator.
  • the invention also relates to a suction excavator with the material handling device, articulated hose carrier, and suction hose.
  • a suction excavator is a vehicle with a chassis that supports a preferably tipping material collection container.
  • a suction excavator has a telescopic arm with two telescopic arms. The end of each telescopic arm facing the container is mounted on a tilting axis around which the material collection container can rotate, with the end of each telescopic arm facing the chassis.
  • one end of the suction hose is attached to the suction excavator, and the other end has a suction nozzle through which material can be drawn in. The drawn-in material is transported through the suction hose and placed into the material collection container.
  • a suction hose is known to have a larger diameter than standard hoses, such as those used for pumping water or supplying liquid concrete.
  • Known articulated hose carriers for suction excavators have adjustable joints between individual sections, allowing the sections to be moved or rotated in a single plane. Furthermore, rotation of the articulated hose carrier around a pivot point is enabled by a rotary drive, with this rotary drive forming the connection between the articulated hose carrier and the vehicle.
  • the plane in which the articulated hose carrier is located The working area can thus be described by the axis of rotation of the rotary drive and the pivot direction of the first link attached to the rotary drive; it is regularly perpendicular to the vehicle floor or chassis.
  • the connection is therefore a rotatable mounting bracket.
  • a typical articulated hose carrier for suction dredgers has a number n of links, preferably n ⁇ 4, with joints located between them, whereby an angular change can be effected between each link by means of an associated drive.
  • n ⁇ 4 a number of links, preferably n ⁇ 4, with joints located between them, whereby an angular change can be effected between each link by means of an associated drive.
  • simpler articulated hose carriers with fewer than four links are also possible.
  • suction excavators have a limited working area or range because their sections can only move in one plane.
  • a broad range of applications is generally preferred for suction excavators, as a wide variety of areas need to be worked on or cleared of material. For example, intersecting pipes in the ground need to be completely cleared, or construction debris needs to be extracted from a building.
  • To cover the required working area it is sometimes necessary to reposition the vehicle. This is necessary, however, as maneuvering space on construction sites is usually limited, or manual assistance by a person using a shovel or similar tool is required. Therefore, a more flexible material handling device, especially one with an additional degree of freedom for the articulated hose carrier, is desirable for certain applications.
  • the articulated arm consists of a swivel base and four segments, the swivel base having a rotary joint controlled by a hydraulic motor.
  • the EP 0 166 800 A1 Figure 1 shows a headpiece for a mobile or stationary refueling system, comprising a refueling coupling and a pipeline.
  • the pipeline consists of five pipe sections, each connected by a swivel joint with a single degree of freedom. Three of the five swivel joints have parallel axes of rotation. The other two swivel joints have axes of rotation perpendicular to the aforementioned axes of rotation of the three swivel joints.
  • the headpiece has an additional swivel joint at one end, which serves as a connection to the refueling system. Due to the use of rigid pipe sections, the refueling range is limited.
  • the articulated hose carrier has at least three links, whereby an angle change can be effected between adjacent links by means of an associated drive.
  • the US 3,495,878 A This describes a pipe device for the pneumatic conveying of bulk material.
  • the device comprises a stationary pipe, a rotatable pipe rotatably connected at one end to the end of the stationary pipe, and a flexible, bendable pipe unit connected at its other end to the rotatable pipe.
  • a first drive unit causes a rotary movement of the rotatable pipe and the flexible pipe unit.
  • a second drive unit is provided for bending the flexible pipe unit, thereby causing a lifting movement.
  • the DE 10 2018 004 334 A1 Describes a suction dredger with a chassis and a superstructure mounted on the chassis.
  • the superstructure includes a suction nozzle for picking up material. and a suction boom arm with at least one arm section for supporting the suction boom.
  • the suction boom arm is pivotable about a first pivot axis running parallel to a vertical axis of the suction excavator.
  • the suction boom arm is mounted at one end facing the superstructure on a support element.
  • the support element, together with the suction boom arm, is pivotable relative to the superstructure about a second pivot axis running parallel to a longitudinal axis of the suction excavator and can also be fixed together with the suction boom arm in various pivot positions relative to the superstructure.
  • the EP 3 399 108 B1 Figure 1 shows an articulated suction arm of a suction dredger.
  • the suction arm comprises at least two parts defined in the same plane and pivotally connected to each other along a first axis perpendicular to the plane.
  • the two parts define a rear and a front end.
  • a base section is pivotally connected to the rear end along a second axis perpendicular to the plane.
  • Pivoting linkages are arranged on the base section to pivot the at least two parts along a third axis defined in the plane.
  • a nozzle located in the region of the front end is configured to connect to the front end of a suction line.
  • the nozzle defines a fourth axis defined in the plane according to an initial position.
  • the suction arm includes a tilting device configured to change the orientation of the nozzle so that the fourth axis can be tilted to one side or the other of the plane.
  • Eccentrically arranged hydraulic cylinders are used as the tilting device, capable of tilting the fourth axis, or the corresponding section of the suction arm, by approximately 10°. Larger inclinations, for example of about 90°, are possible due to the The chosen design does not allow for this. Therefore, certain areas underground cannot be reached by the nozzle.
  • An object of the present invention is to provide a material handling device for suction dredgers with an enlarged or more easily accessible working area, without the risk of the suction hose being damaged or its diameter reduced during the movement of the articulated hose carrier, so that a continuous material flow is maintained in any working position.
  • a working position of the suction nozzle should be accessible from different directions without the suction dredger having to change its position.
  • the problem is solved by a material handling device with an articulated hose carrier and a suction hose according to the attached claim 1, and by a suction dredger with the material handling device with articulated hose carrier and suction hose according to the dependent claim 10.
  • the material handling device comprises an articulated hose carrier and a suction hose, wherein the articulated hose carrier supports and guides the suction hose.
  • the material handling device is attached to a suction excavator, so that material can be conveyed via the suction hose into a container of the suction excavator.
  • the necessary negative pressure and suction airflow are generated by a fan unit of the suction excavator.
  • the articulated hose carrier has a rotatable mounting bracket at a first end, by means of which the articulated hose carrier can be attached to the suction excavator.
  • the mounting bracket can be a
  • the articulated hose carrier is a pivot joint or swivel joint with an axis of rotation.
  • the axis of rotation of the mounting bracket is typically perpendicular to the vehicle floor, and the mounting bracket is usually attached to the rear of the suction excavator in the direction of travel.
  • the mounting bracket allows the articulated hose carrier to be moved with the suction hose.
  • the material handling device includes a suction nozzle, which is attached to the distal end of the suction hose.
  • the articulated hose carrier consists of a number n of links, where n ⁇ 3, and preferably n ⁇ 4, between each of which a hinge joint (hereinafter also referred to simply as a joint) is formed.
  • Each hinge joint is associated with a drive, the drives being preferably hydraulically operated. Alternatively, electric or pneumatic drives can be used. All joints have the same degree of freedom, i.e. , all links of the articulated hose carrier can be moved or pivoted in a single common plane by means of the joints and their drives.
  • the material receiving device further comprises at least one pivot joint, which is arranged between the last (most distal) hinge joint located on the link where the suction nozzle is situated, and the first hinge joint located closest to the rotatable mounting bracket.
  • the pivot joint is located between the last and the penultimate hinge joint, i.e., between the two hinge joints furthest from the proximal end of the articulated hose carrier.
  • the swivel joint is located one or two links further towards the proximal end of the joint hose carrier. Assembled. This increases the range of motion of the suction nozzle, as several links can be moved out of the plane defined by the axis of rotation of the mounting bracket and the position of the second link.
  • two swivel joints can also be arranged on the articulated hose carrier. This allows the articulated hose carrier to be guided around a corner of a building or a similar obstacle, for example.
  • the material handling device advantageously enables work in larger work areas without having to move the suction excavator to which the device is attached.
  • the swivel joint makes it possible, for the first time, to move entire sections of the articulated hose carrier out of the usual working plane.
