Definitions

  • the present invention relates to the structure of a construction machine which travels by means of a running truck and performs work by two types of working machines, i.e., a first working machine and a second working machine.
  • Fig. 2 shows a conventional construction machine for civil engineering operations having two types of working machines.
  • the construction machine 30 has a loading shovel 32, which is a loading machine, installed on the front of a vehicle body 31, and a backhoe 33, which is an excavating and earth removal machine, installed on the rear of the vehicle body 31.
  • the loading shovel 32 is able to rotate upwards and downwards within the range shown by the arrow A, but is unable to rotate side to side (horizontally), and the backhoe 33 is able to rotate upwards and downwards within the range shown by the arrow B, but is only able to rotate 90° to either side horizontally.
  • a construction machine 30 with such a structure cannot have the loading shovel 32 on the front and the backhoe 33 on the rear positioned in the same horizontal direction.
  • An advantage of this structure is that it is not necessary to prepare two construction machines, that is, a construction machine for excavation and earth removal work and a construction machine for loading work.
  • the construction machine of this structure has poor operating efficiency because the loading shovel 32 for loading work and the backhoe 33 for excavation and earth removal work can only be used one at a time.
  • the present invention has been made in view of the foregoing situation, and it is an object of the present invention to greatly improve operating efficiency by enabling high level work, wherein two types of working machine are made to operate in cooperation with each other while expanding the operating range of the working machines.
  • the present invention provides a construction machine which travels by means of a running truck, for carrying out work using a first working machine and a second working machine, characterized in that a first base table for supporting the first working machine is disposed above the running truck in such a manner as to rotate freely in a horizontal direction; and a second base table for supporting the second working machine is disposed above the first base table in such a manner as to rotate freely in a horizontal direction.
  • the operating range is expanded and working efficiency is greatly improved, because the first working machine and second working machine can rotate freely in a horizontal direction without interfering with each other.
  • first working machine and second working machine can be positioned on the horizontal direction, it is possible for these two working machines to operate in cooperation with each other so as to enable high level work whereby the working efficiency is greatly improved.
  • Fig. 1 is a side view showing the configuration of a construction machine 20 according to an embodiment of the invention.
  • a running truck 1 is a truck having the function of traveling.
  • the running truck may be of, for example, a crawler type.
  • a wheeled truck (with tires) may also be employed.
  • a turning mechanism 3 which freely turns 360° in a horizontal direction, is provided, and a first base table 2 is fixedly provided on this turning mechanism 3.
  • a loading shovel 4 which is a first working machine, is supported on the end of this first base table 2.
  • the loading shovel 4 can thereby be rotated freely in a horizontal direction through the operation of the turning mechanism 3, as required.
  • the loading shovel 4 is supported by the first base table 2 in such a manner as to move up and down freely.
  • the backhoe 7 can thereby be positioned arbitrarily ,as required, in a horizontal direction through the operation of the turning mechanism 6 without interfering with the loading shovel 4.
  • the backhoe 7 is an excavating front end comprising an excavating bucket and a multiple-jointed arm.
  • a turning mechanism 10 which freely turns 360° in a horizontal direction, is provided on top of the second base table 5, and a driving floor 12 is provided on this turning mechanism 10.
  • a driver's seat and group of operating levers 9 are provided on this driving floor 12.
  • the driver's seat 8 can thereby be positioned arbitrarily in a horizontal direction through the operation of the turning mechanism 10, as required. This allows the driver's seat 8 to be oriented in the same direction as the direction in which the loading shovel 4 and the backhoe 7 are turned. When work is carried out in a particular direction, the operator can always view the work without being in a very uncomfortable position.
  • the turning centers of the turning mechanism 3, the turning mechanism 6, and the turning mechanism 10 may be on the same axis or offset appropriately with respect to each other.
  • 11 is a body cover which houses an engine for driving the running truck 1 and working machines 4 and 7, hydraulic equipment, etc.
  • the backhoe 7 can be turned in a full 360° range as noted above, it is possible to carry out excavation and earth removal work in a full horizontal range, like with an ordinary hydraulic shovel. Therefore, operating efficiency is greatly improved, because, unlike the conventional construction machine 30 having two types of working machine as shown in Fig. 2, the range for carrying out excavation and earth removal work is not limited.
  • the loading shovel 4 can also be turned in a full 360° range, the loading shovel 4 can be placed in a position and orientation which do not interfere with the excavation and earth removal work by the backhoe 7.
  • the loading shovel 4 can also function as an outrigger to ensure stability during work performed with the backhoe 7.
  • An ordinary small hydraulic shovel generally has an earth removal blade installed on the front of the vehicle.
  • This earth removal blade can function as an outrigger for ensuring stability during excavation work, but can ensure adequate stability only when the shovel is oriented in the same forward direction as the earth removal blade.
  • the loading shovel 4 can function as an outrigger by positioning it in the same direction as in the backhoe 7. As a result, stability is ensured for the full range of turning, and is thereby vastly improved.
  • loading work can be carried out in a full range of horizontal directions. For this reason, carrying out of loading work is not limited to in a forward direction, as with the conventional construction machine 30 having two types of working machines shown in Fig. 2. In fact, the loading work can be carried out in flexible loading attitudes so that operating efficiency is greatly improved. Incidentally, loading work using this loading shovel 4 can be carried out smoothly if the second base table 5 is turned in a direction so as not to interfere with the work and if the backhoe 7 is stowed in a folded position.
  • the operating efficiency can be greatly improved by turning the loading shovel 4 and backhoe 7 in the same direction so that such a work cooperation can be made with these working machines that the backhoe 7, having excavated the earth and sand or gravel, directly loads the excavated earth, etc. to the loading shovel 4.
  • the working machines 4 and 7 are able to rotate in a full range (360°) in a horizontal direction.
  • the turning range limited to a necessary range. Since the work cooperation by these two working machines can be carried out as long as the loading shovel 4 and backhoe 7 are turned in the same direction. Therefore, the loading shovel 4 may be limited to a turning range of 90° to either side thereof.
  • the working machines are presumed to be a loading shovel 4 and a backhoe 7, other embodiments in which other types of working machines are used as appropriate for the work, are also possible.
  • an earth moving blade capable of moving upwards and downwards may be installed instead of a loading shovel 4 capable of moving upwards and downwards.
  • the second working machine 7 is installed rotatably in a horizontal direction, above the first working machine 4 which is rotatable in a horizontal direction.
  • the present invention is not limited to this configuration and other types of working machine, depending on the work, may be installed, so as to rotate freely in a horizontal direction, above the second working machine 7.
  • the present invention can be applied to other types of machinery which carry out work using two types of working machines, as well as to construction machinery.
