Definitions

  • the invention relates to an excavator, consisting of a support frame, each with a pair of support arms on opposite sides thereof, on which wheel and / or footrests are arranged, and a superstructure which can be rotated about an approximately vertical axis relative to the support frame and on which a digging, Cutting or machining tools carrying boom attacks.
  • Excavators of this type are very mobile and can therefore be used in the most difficult terrain, because to move the excavator, the front end of the support frame is raised during operation by supporting the digging tool against the ground, the excavator by moving the tool supporting boom moved back and forth or steered by turning the superstructure and then lowered back onto the footrests, so that the excavator moves gradually by repeating these operations.
  • To adapt the excavator to uneven terrain it is known to pivot each support arm independently and independently of the others in a vertical plane. However, only a so-called walking movement is possible here.
  • the present invention has for its object to provide an excavator that can perform both a pure walking movement and a pure driving movement without the need for the arrangement of edges on all four support arms, the steering should be made possible in a simple manner .
  • At least one height-adjustable wheel is arranged on the superstructure, and at least one of the wheels arranged on the superstructure and on the support arms is designed to be driven.
  • a quick changeover is created in a structurally simple manner in order to be able to convert the excavator from a pure walking movement into a pure driving movement.
  • the height of such a wheel can be adjusted using structurally simple means, no additional measures being required for the steering during the travel movement, since this steering can be carried out in a simple manner by rotating the superstructure about an approximately vertical axis.
  • the measure according to the invention also brings a significant advantage in terms of space, since wheels do not have to be additionally attached to the free ends of at least one pair of support arms. It is therefore possible to design the footrests arranged at the free ends of these support arms in a necessary manner, since the space conditions are not influenced by additional wheels to be attached. In addition, the usability of the excavator is much greater, since relatively narrow support arms are required, especially in difficult and steep terrain, on which then no additional ballasts projecting laterally should be at the front.
  • the excavator operator can quickly switch from a walking operation to a driving operation, it being very important that the wheel additionally arranged on the superstructure of the excavator does not impede the excavator operator in terms of either the least or the unobstructed view.
  • the excavator consists of a support frame 1, a pair of support arms 2 and 3 being arranged on opposite sides of the support arm frame 1. Wheels 4 and footrests 5 are arranged on these support arms.
  • the superstructure 6 of the excavator can be rotated relative to the support frame 1 about an approximately vertical axis 7.
  • a boom 8 acts on this superstructure 6, only a part of this boom 8 being shown in FIGS. 1 and 3.
  • G rab cutting or machining tools are then arranged at the free end of this boom 8, the movement of the boom and these tools being effected by hydraulic cylinders.
  • a height-adjustable wheel 9 is arranged on the superstructure 6.
  • This d ad 9 is expediently arranged on the side of the superstructure 6 opposite the boom 8 and held at the free end of an arm 11 which can be pivoted about a horizontal axis 10 on the superstructure.
  • This arm 11 is pivotally held by a hydraulic cylinder 12.
  • One or both wheels 4 can be equipped with a hydraulic drive in order to achieve a driving movement.
  • the excavator When working, the excavator is in the position shown in Figs. 1 and 2, i.e. digging or other work is carried out with the boom between the two support arms 2.
  • the support arms 3 with the wheels 4 are arranged opposite the boom 8.
  • the tool arranged at the free end of the boom 8 is supported on the ground, and by lifting and bending the boom 8 the support arms 2 are raised on the one hand and on the other hand the excavator itself is pulled further in the direction of the arrow 13.
  • the support arms 2 After lifting the boom, the support arms 2 are lowered again so that the footrests 5 are used. Work can now continue at the new location.
  • the wheel 9 arranged on the superstructure 6 is located on the rear of the driver's cab 14 and is therefore in no way a hindrance during the excavation work.
  • the wheel 9 is also provided on the side of the superstructure 6 opposite the arm 8.
  • a supporting part 20 is connected to the superstructure 6 so as to be pivotable about a horizontal axis 21, wherein this supporting part 20 can be pivoted downwards into a driving position or upwards into a rest position by hydraulic cylinders 12.
  • the wheel 9 is held in an approximately U-shaped support arm 23, the support arm 23 being pivotable about the axis 22 relative to the support part 20.
  • This axis 22 lies in an approximately vertical plane and is oriented approximately vertically in the driving position (FIG. 6), the angle of the axis 22 to the vertical depending on the adjustment angle of the support part 20 deviating accordingly from the vertical. It only has to be achieved that the wheel 9 receives a steering lock by rotating the support arm 23 about the axis 22.
  • the wheels 4 and 9 can be dimensioned differently or can also have the same size (diameter, width).
  • the pivot axis 22 between the support arm 23 and the support member 20 is seen in the operating position of the wheel 9 at a horizontal distance from the axis of rotation 24 of the wheel 9.
  • the wheel 9 directly below the support part 20, so that the support arm 23 is aligned in an approximately vertical position, in which case the axes 22 and 24 intersect.
  • a corresponding steering deflection can also be achieved in a simple manner in such an embodiment.
  • a hydraulic cylinder 25 is provided which engages both on the support arm 23 and on the support part 20.
  • This hydraulic cylinder 25 engages one leg of the U-shaped support arm 23, so that when the piston of the hydraulic cylinder is pushed or retracted, the support arm 23 is entangled about the axis 22 becomes.
  • the support part 20 is shown in the drawing as a closed plate, it being possible, of course, to choose from different design variants. Of course, a pure frame construction is also possible. If appropriate, it would also be possible with a corresponding structural design to provide only one hydraulic cylinder 12 instead of the two hydraulic cylinders 12 for pivoting the supporting part 20.
  • the structural design of the support arm can also be carried out in various ways. It would also be conceivable to provide only a type of L-shaped design for the support arm 23, so that the wheel 9 can then be attached to one leg of this support arm 23 on the fly.
  • the excavator For digging or other work, the excavator is in a position in which the boom lies between the two support arms 2, that is to say in a position pivoted by 180 ° with respect to the illustration in FIGS. 1 and 2. If a longer distance is now to be covered with the excavator, it is easy to switch to driving mode, namely by initially rotating the superstructure 6 about the vertical axis 7 by approximately 180 °, so that the supporting frame 1 remains in the same position and thus the support arms 2 and 3 of the boom 8 now point in the other direction, as shown in FIGS. 1 and 2. Now the wheel 9 with the supporting part 20 can be pivoted downwards by the hydraulic cylinders 12, so that the wheel 9 is supported on the drivable floor. The support arms 2 and thus the footrests 5 are raised solely by correspondingly depressing the wheel 9. Of course, it is possible to additionally raise the footrests 5 by actuating the hydraulic cylinders 15.
  • the superstructure can remain aligned in the longitudinal direction of the excavator, particularly in narrow passages, so that in such cases the wheel alone can be pivoted relative to the height-adjustable support part.
  • the configuration according to the invention is thus designed in a structurally simple manner so that an excavator which essentially functions as a walking excavator when used in work is so that it can be continuously converted into a mobile excavator if required.
