Definitions

  • the present invention relates to a hydraulic working machine such as a hydraulic excavator.
  • the hydraulic working machine such as a hydraulic excavator is provided with a swing frame provided free to swing on a travel body.
  • a cab for an operator is arranged in a part of the swing frame, and a counterweight is mounted at the rear of the swing frame.
  • various apparatuses such as main apparatuses such as a hydraulic motor and an internal combustion engine as a drive source therefor, various hydraulic cylinders, a working oil tank, a fuel tank for storing fuel of the internal combustion engine, and the like.
  • various apparatuses mounted on the swing frame have a variety of shapes and sizes, and the swing frame also has various sizes depending on the mounting space.
  • the aforementioned cab includes a plurality of shapes of cabs such as a small cab in which a space for an operator is relatively narrow, a relatively large cab which forms a wide space for an operator, and the like.
  • the aforementioned counterweight is provided on the peripheral edge at the rear of the swing frame, but the mounting position of the counterweight (the distance from a rotational shaft of the swing frame) is sometimes changed depending on the difference of uses and constitutions. In such a case, it is necessary to separately design and produce different shapes of swing frames depending on the size of a cab, or a mounting position of a counterweight, posing a disadvantage in that the cost is high.
  • a small swing frame in which a swing locus is substantially accommodated within a circle whose diameter is a clearance, whereas in the case where the actual working spot is relatively wide so that the large main apparatuses are required, a swing frame is also large.
  • the swing frame provided on the hydraulic working machine is different in size adapted for the use. This also makes necessary to design and produce different shapes of a plurality of swing frames, posing a disadvantage in that the cost is high.
  • the hydraulic excavator of this kind there exists those having a plurality of body shapes even for the same class of machine (the main apparatuses such as an internal combustion engine, a tank, etc. are the same). That is, there exists one provided with a swing frame in which swing locus is substantially accommodated within a circle whose diameter is a clearance, and one in which a counterweight extends backward of the body leaving a relatively long distance from a rotary shaft of a swing frame in order to make a weight of a counterweight relatively small so as to reduce the weight of the body. Since these are different in the size of the cab and the position of the counterweight even for the same class of machine, it is necessary to produce swing frames peculiar thereto. Further, it is necessary to separately produce bonnets corresponding to different shapes of swing frames, thus posing a disadvantage in that the cost of producing various hydraulic excavators is high.
  • the present invention overcomes such disadvantages as noted above. It is an object of the present invention to provide a hydraulic working machine in which even if mounting spaces of various apparatuses on a swing frame or uses of the hydraulic working machines are different, and even if the size of cabs or position of counterweights are different in the same class of machine, basic parts of the swing frame are made common to thereby reduce the cost.
  • a hydraulic working machine comprising a travel body and a swing frame provided free to swing on the travel body, the swing frame comprising a basic frame and an extending frame for extending the basic frame, whereby the extending frame is mounted on the basic frame as necessary corresponding to the arrangement on the swing frame of a cab, an internal combustion engine, various apparatuses including a hydraulic apparatus and a counterweight.
  • the basic frame constitutes the swing frame.
  • an extending frame is mounted on the basic frame to constitute a swing frame having a wide mounting space. The extending frame is mounted on the basic frame as necessary as described above whereby the basic frame is made common to form a necessary mounting space, thus reducing the production cost.
  • the basic frame has a minimal size enough to accommodate the cab, the internal combustion engine and various apparatuses including the hydraulic apparatus to form a shape that can be swung substantially within a clearance of the travel body.
  • the basic frame sometimes has a portion projecting somewhat outwardly of the clearance of the travel body while being affected by the arrangement of main apparatuses such as the internal combustion engine and various tanks to be mounted. Even in this case, it will suffice to be formed so as to be substantially swung within the clearance of the travel body.
  • plural kinds of said extending frames are formed in different shapes corresponding to a mounting position of the basic frame.
  • the extending frame is mounted on the basic frame at a location merely required according to the shape of the various apparatuses whereby the swing frame can be formed into a desired shape without newly performing the design and production, thus preventing the increase of cost.
  • the extending frame is mounted on the basic frame depending on the bottom shapes of various cabs.
  • the extending frame is mounted on the basic frame according to various cabs to thereby enable the selective mounting of a cab for a small swing having a shape capable of being swung substantially within a clearance of the travel body, and a normal type cab having a shape outwardly of a clearance of the travel body at least during the swinging.
  • the extending frame is extended from the basic frame, and at least a part of the normal type cab is mounted on the extending frame. That is, in the case where the cab mounted on the extending frame is protruded outwardly from the cab mounting portion, the extending frame is mounted on the cab mounting portion to support the bottom of the cab.
  • the extending frame is mounted on the basic frame according to the mounting position of the counterweight. That is, in the case where the counterweight is mounted on the counterweight mounting portion of the basic frame, the swing frame is constituted without provision of the extending frame. In the case where the counterweight is mounted at a position rearwardly of the counterweight mounting portion of the basic frame, the counterweight can be mounted at a position rearwardly of the counterweight mounting portion of the basic frame through the extending frame.
  • the counterweight for a small swing is mounted on the basic frame without provision of the extending frame.
  • the extending frame is provided on the basic frame to form the extending type counterweight. More specifically, the extending type counterweight is constituted by an extending frame comprising a weight supporting member mounted on the basic frame and a weight member mounted on the extending frame.
  • the weight supporting member which is the part of the extending frame is provided on the basic frame and the weight member is provided on the weight supporting member.
  • An under cover is provided on the basic frame when the extending type counterweight is mounted to thereby cover a gap between the basic frame and the weight member.
  • the extending frame comprising the frame extending member mounted on the basic frame and the weight member are constituted integrally whereby the extending type counterweight can be provided in the state where the gap between the basic frame and the weight member is covered without an under cover.
  • the weight of the extending type counterweight is made smaller than that of the counterweight for a small swing to thereby make the shape of the swing frame common to reduce the weight of the body.
  • the counterweight for a small swing may be mounted without mounting the extending frame on the basic frame.
  • the extending frame is merely provided.
  • the end shape of the counterweight for a small swing is of a substantially circular shape around a swinging axis of the basic frame on which the counterweight for a small swing is mounted
  • the end shape of the extending type counterweight is of a substantially circular shape having substantially the same radius as the counterweight for a small swing.
  • the rear end of the extending type counterweight is made to have the same shape as the rear end of the counterweight for a small swing.
  • a rear bonnet for covering the rear portion of the basic frame and a bonnet for covering the front portion of the basic frame are provided.
  • the extending type counterweight provided with an extending frame is provided at the rear of the basic frame, the extending frame is covered by the rear bonnet, and an intermediate bonnet for covering the rear portion of the basic frame is provided between the rear bonnet and the front bonnet.
  • the gap between the rear bonnet and the front bonnet can be covered by the intermediate bonnet. Further, since the shape of the rear bonnet can be made common, the increase of production cost can be reduced.
  • a deck cover corresponding to the counterweight for a small swing and an extending deck cover corresponding to the extending type counterweight are selectively mounted on the basic frame.
  • the gap formed when the extending type counterweight is mounted on the basic frame can be filled by the extending deck cover.
  • a hydraulic working machine comprising a travel body and a swing frame provided free to swing on the travel body, the swing frame comprising a basic frame and an extending frame for extending the basic frame, whereby the extending frame being mounted on the basic frame as necessary corresponding to the constitution required according to the uses of the hydraulic working machine.
  • the extending frame is mounted on the basic frame to form a space capable of mounting the large main apparatuses.
  • the basic frame can be used common, thus reducing the cost.
  • the plural kinds of the extending frames are formed different in shape corresponding to the mounting position of the basic frame, and the extending frames are separately selectively mounted on the basic frame whereby the extending frames can be mounted at locations as necessary for the uses and the swing frame can be formed into the desired shape without newly performing design and production, thus reducing the cost.
  • a hydraulic working machine comprising a travel body; a swing frame provided free to swing on the travel body, the sing frame comprising a basic frame formed into a shape capable of being swung substantially within a clearance of the travel body, and an extending frame for extending the basic frame; a boom journalled vertically rotatably on the swing frame, the boom being journalled rearwardly of a front end edge of the basic frame; a normal type cab having a shape extended outwardly of the clearance of the travel body at least during the swinging, the normal cab being mounted on one side in a lateral direction of the boom in the basic frame and partly mounted on the extending frame; and a counterweight for a small swing having a shape capable of being swung substantially within a clearance of the travel body, the counterweight for a small swing being mounted at the rear of the basic frame.
  • the extending frame is provided frontwardly of the basic frame to mount the normal type cab thereon, whereas the counterweight for a small swing is mounted at the rear of the basic frame so that only the rear portion can be swung within a clearance.
  • the operator can work pleasantly in the wide space for an operator without worrying about the rear portion in the actual working spot.
  • the boom is journalled at the position at the rear of the front end edge of the basic frame whereby even if the counterweight for a small swing capable of being swung within a clearance is provided, the stability of the body can be enhanced by the balance relative to the boom.
