Definitions

  • the present invention relates to an excavator, in particular Mini excavator, according to the preamble of claim 1.
  • Mini excavators generally use rubber tracks mobile excavators understood. These devices can drive through door openings of a building shell, and are called so-called Construction robots with hydraulic hammers instead of digging holes also used in building renovation.
  • a driver's cabin should be as comfortable as possible be equipped for the user.
  • a driver's seat with sufficient suspension be trained, which, however, a lot of space in the driver's cabin needed.
  • Battery a cabin heater and for example for a dashboard is needed.
  • a cabin heater and for example for a dashboard is needed.
  • Both of the above liquid tanks are usually below the driver's seat or in the engine compartment. This has however, the consequence that, for example, when arranging the Fuel tank under the driver's seat, no space for one Cabin heating remains.
  • the arrangement of the hydraulic oil tank in the engine compartment leads to heating of the oil through the engine heat, making larger oil coolers necessary become, which in turn leads to increased space requirements leads or deteriorates engine accessibility.
  • the object of the invention is therefore with an arrangement of Liquid tanks in the engine compartment or in the driver's cabin to avoid associated disadvantages and at the same time the noise isolation an excavator, especially a mini excavator, to improve.
  • the at least one is essentially across the width of the superstructure extending liquid tank thus fulfills a double function, namely simultaneous noise reduction the separately arranged engine and Valve spaces. Furthermore, an arrangement is according to the invention a liquid tank inside the engine compartment avoided, so that, for example, in the case of a hydraulic oil tank less expensive oil cooling compared to the prior art must be provided. Finally stands by arrangement of the at least one liquid tank according to the invention an increased space in the driver's cabin to disposal.
  • Excavator is a driver's cab with a driver's seat the superstructure of the excavator essentially above of the at least one liquid tank.
  • the engine compartment, the valve compartment and the at least one liquid tank at least partially arranged within a frame of the uppercarriage.
  • the driver's cabin is expediently located below the driver's seat a heating device is arranged.
  • a heating device is arranged.
  • the arrangement according to the invention in the driver's cabin available space in an optimal way be used. It is for example due to the invention Arrangement of the liquid tanks also easily possible to have a relatively large driver's seat To provide a spring frame in the driver's cabin.
  • the Excavator a first and a second liquid tank, these liquid tanks with one positive each or complementarily negatively inclined side wall to each other issue.
  • Liquid tanks are a particularly simple installation of the tanks, for example, in the frame of the superstructure. This allows the two liquid tanks tightly or wedge-like to each other with optimal use of space create, which makes the sound insulation effect favorable is influenced.
  • the liquid tank with The tolerance requirements are also diagonally adjacent side walls reduced to the liquid tanks, whereby an inexpensive production is possible.
  • the respective inclined side walls of the Liquid tanks parallel to the longitudinal direction of the excavator.
  • the at least one liquid tank is advantageously made of metal, especially steel, or plastic. While steel tanks have a particularly high mechanical Strength are excellent, leads in particular the use of plastic tanks for further improvement noise insulation or isolation.
  • the mini excavator shown in Figure 1 has a crawler undercarriage 1 and an uppercarriage 2.
  • the uppercarriage 2 is formed with an uppercarriage frame 6 in which an engine compartment 10 (partially) and a valve chamber 11 are arranged are.
  • a driver's cab 4 is essentially in the middle the superstructure frame 6 arranged.
  • a seat console 13 In the driver's cabin 4 a seat console 13 with a driver seat 14 arranged thereon intended.
  • a heater is located below the driver's seat 14 15 arranged.
  • liquid tanks 20, 21 are two liquid tanks 20, 21 arranged. From Figure 2 it can be seen that the liquid tanks 20, 21 together over the entire Extend the width of the superstructure frame 6. they form thus a separation area between engine compartment 10 and valve compartment 11.
  • the engine compartment 10 is at the rear of a hood 17 or a rear weight 7 limited.
  • the engine compartment 10, which is usually a strong noise and Heat generation is due to a console rear wall 16 of the seat console 13 of the driver's cab 4 and the rear Walls of the tanks 20, 21 to the driver's cabin 4 and Valve chamber 11 separated.
  • the one with liquid, i.e. in the present Example fuel or hydraulic oil, filled Liquid tanks 20, 21 have a strong noise reduction Effect on, especially if made of plastic and are filled with liquid.
  • the driver's cabin 4 is the rear wall of the console 16 covered with insulating material.
  • the expansion is Liquid tanks 20, 21 forward through the dimensions of an articulated cylinder 19 and arranged next to and above it Control devices 12, in particular valves, and to the rear by the dimensions of the arranged in the engine compartment 10 Motor 8 limited.
  • the articulated cylinder 19, which is a limited one Swiveling an excavator boom 3 about an articulation axis 33 causes, together with a rotary motor 35, the Superstructure moved by a pivot bearing 5 relative to undercarriage 1, the tank limit to the valve compartment 11.
  • FIG. 2 shows, as mentioned above, that the liquid tanks 20, 21 over the full width of the superstructure frame 6 extend.
  • Figure 2 is also one with the designed as a hydraulic oil tank Liquid tank 20 connected via suction lines 34 Hydraulic pump 9 shown, which via pressure lines 32 for example the articulated cylinder 19 with hydraulic oil acted upon. Pressure lines 32 are in one Line channel 31 arranged.
  • Figure 3 shows a cross section through the liquid tanks 20, 21, which are arranged in the superstructure frame 6.
  • solid lines of the liquid tanks 20, 21 shows the assembly position, while dash-dotted lines serve to clarify the installation process.
  • the superstructure frame 6 formed with a recess on its top, through which the liquid tanks 20, 21 can be inserted.
  • the liquid tank designed as a fuel tank 21 which is approximately 30 to 40% of the cross-sectional area of the uppercarriage frame 6 occupies through the recess inserted into the superstructure frame 6 and so far to the right moved until its right side wall 41 on the inside the superstructure frame 6 rests.
  • the larger, approximately 60% of the cross-sectional area of the superstructure frame 6 engaging, designed as a hydraulic oil tank 20 second liquid tank through the recess in the superstructure frame 6 will be introduced.
  • the fuel tank 21 with a positive incline Sidewall 23 formed.
  • the hydraulic oil tank 20 has a complementary, negatively inclined Side wall 24 on. After inserting the liquid tank 21 and its shift to the right until it touches with the inside of the upper frame 6 Hydraulic oil tank 20 in the dashed lines in Figure 3 indicated way, taking advantage of the two positive or negatively inclined side walls 23, 24, by means of a pivoting movement through the recess in the superstructure frame 6 are brought into its assembly position. Means the formation of complementary trained Side walls 23, 24, it is thus possible, essentially the entire cross section of the superstructure frame 6 with Fill in the tank space.
  • the conduit 31, which is a small one Occupies part of the cross section of the superstructure frame 6, can in the event that between the lines 32 and the Hydraulic oil tank 20 a gap remains, with insulating material lined against noise and heat become.
  • the removal of the liquid tanks 20, 21 takes place in reverse order, i.e. first is hydraulic oil tank 20 by means of a pivoting movement through the recess in Removed superstructure frame 6, after which the fuel tank 21st after shifting to the left in the area of the recess is also easily removable. It should be noted that the remaining side walls of the liquid tanks 20, 21 a parallel, inclined or other appropriate Can have alignment.
  • the hydraulic oil tank 20 is usually located with its Line duct 31 on the side of the excavator, on the the hydraulic pumps 9 are also arranged.
  • Figure 3 is the hydraulic oil tank 20, for example, with an inflow flange 29 shown with a built-in oil filter 30.
  • the hydraulic tank 20 is usually replaced by a Flow guide wall 27, which the hydraulic oil in a desired direction flows to the total volume of oil to participate in the blending process.
  • the hydraulic tank is thus in an inflow space 28 and Suction chamber 25, on the suction line connections 26 to the hydraulic pumps 9 are attached, divided. Inflow space 28 and suction chamber 25 can optionally in their position be exchanged.
  • the fuel tank 21 is shown as an example in FIG Filler neck 22 shown, depending on the spatial conditions also on a side wall of the fuel tank 21 may be appropriate.
