Description

  The present invention relates to a construction machine sensor storage device that stores a sensor that obtains three-dimensional distance data by projecting a light beam onto an object.

  Construction equipment such as backhoes and vibrator backhoes is contaminated by rebounding of earth and sand, concrete, etc. when working on site. Since the rebound of such earth and sand and concrete will be settled over time, cleaning work is performed at an early stage after the construction equipment is used.

Such a cleaning operation is performed by spraying ultra-high pressure water onto the soiled portion with a water jet gun or the like. For example, Patent Document 1 (Japanese Patent Application Laid-Open No. 2011-173064) discloses a water jet gun that injects ultrahigh pressure water from an injection nozzle, which is used in a cleaning operation of construction equipment.

It is a top view of construction equipment 1 in which sensor storage device 10 for construction machines concerning an embodiment of the present invention is carried.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a construction device 1 on which a construction machine sensor storage device 10 according to an embodiment of the present invention is mounted. FIG. 2 is a top view of the construction equipment 1 on which the construction machine sensor storage device 10 according to the embodiment of the present invention is mounted.

  In the present embodiment, a backhoe will be described as an example of the construction equipment 1 on which the construction machine sensor storage device 10 is mounted. However, the construction machine sensor storage device 10 according to the present invention may include other constructions such as a vibrator backhoe. It can also be applied to the device 1.

  In the construction equipment 1, it is assumed that an operator gets on the cockpit 7 and performs an operation. Moreover, the construction equipment 1 has the turning part 5 which turns by an operator's operation.

  In order to cope with the computerized construction, the construction device 1 is provided with a sensor 50 on the roof portion 8 of the cockpit 7. In the present embodiment, as such a sensor 50, a three-dimensional scanner that projects light rays onto an object and acquires three-dimensional distance data that is a set of point cloud data will be described as an example. However, the sensor to be used is not limited to this.

  As the sensor 50, for example, UST-20LN manufactured by Hokuyo Electric Co., Ltd. is used. Data acquired by such a sensor 50 is taken into an information processing terminal such as a personal computer provided in the cockpit 7 and is referred to by an operator appearing in the cockpit 7.

  The sensor 50 as described above is stored in the construction machine sensor storage device 10 according to the present invention. The construction machine sensor storage device 10 is attached to the roof portion 8 of the cockpit 7.

  First, as a construction machine sensor storage device 10, a pair of first rail members 11 are attached to the roof portion 8 of the cockpit 7 from the front to the rear. A pair of second rail members 12 are provided so as to be movable on the pair of first rail members 11. The pair of second rail members 12 are movable in the X-X ′ direction in the drawing.

  Further, a cover case 20 is provided on the pair of second rail members 12 so as to be movable on the second rail members 12. A sensor 50 is accommodated in the cover case 20, and the cover case 20 is movable in the Y-Y 'direction in the figure. Therefore, the cover case 20 is movable in the two-dimensional direction of the X-X ′ direction and the Y-Y ′ direction on the roof portion 8.

  Further, the cover case 20 can be temporarily fixed by fixing means (not shown) at any point within the movable range in the X-X ′ direction and the Y-Y ′ direction. Thereby, it is possible to prevent the cover case 20 from moving due to vibration or the like.

  Furthermore, the cover case 20 is configured to be able to release the temporary fixing and move the movable case to an arbitrary point within the movable range. Therefore, the cover case 20 that houses the sensor 50 can be positioned at the most suitable position for acquiring data by the sensor 50 within the movable range.

  The cover case 20 may be moved manually within the movable range in the XX ′ direction and the YY ′ direction. However, the cover case 20 may be moved non-manually by providing driving means. You can also In that case, it is preferable that the cover case 20 is moved by an operation from inside the cockpit 7. In addition, the temporary fixing can be performed non-manually, and in this case as well, the temporary fixing / releasing of the cover case 20 is performed by an operation from inside the cockpit 7. It is preferable to configure.

  The cover case 20 is a substantially rectangular parallelepiped case body having no one surface. The cover case 20 houses a sensor 50 such as a three-dimensional scanner. The sensor 50 projects a light beam onto the object, projects the light beam from the opening 25 of the cover case 20, and acquires data relating to the front of the cockpit 7. The data acquired by the sensor 50 is assumed to be used for construction management.

  In the vicinity of the opening 25 of the cover case 20, a cover plate 30 that rotates about a rotation shaft 27 is provided. The cover plate 30 is rotated about the rotation shaft 27 so that the cover 25 has an opening 25 and the cover case 20 has an opening 25 closed by the cover 30. Can be taken.

  Although the opening 25 can be opened and closed by manually rotating the lid plate 30, the opening and closing of the opening 25 can be performed by rotating the lid plate 30 non-manually by providing a driving means or the like. Can also be configured. In the latter case, it is preferable that the opening 25 is opened and closed by the operation of the cockpit 7 by the rotation of the cover plate 30.

  FIG. 3 is a view for explaining opening and closing of the lid plate 30 of the construction machine sensor storage device 10 according to the embodiment of the present invention, and FIG. 3 (A) shows a state in which the opening 25 is opened by the lid plate 30. FIG. 3B is a diagram showing a state in which the opening 25 is closed by the lid plate 30.

  When the construction equipment 1 is engaged in work at the site, the state shown in FIG. The state in which the opening 25 in FIG. 3A is opened indicates a state in which the sensor 50 is operated to project a light beam onto the object and acquire three-dimensional distance data in front of the cockpit 7. ing. Thereby, the operator can refer to the data acquired by the sensor 50 in the cockpit 7.

  On the other hand, after the construction equipment 1 is used on site, the construction equipment 1 is cleaned with ultra-high pressure water. At this time, the state shown in FIG. As shown in FIG. 3B, by setting the opening 25 to be closed by the cover plate 30, it is possible to prevent the ultrahigh pressure water from being applied to the sensor 50 and damaging the sensor 50.

  Note that it is not preferable that the high-pressure water is applied to the cover case 20 in which the sensor 50 is accommodated during the cleaning operation of the construction equipment 1 with the ultra-high-pressure water. It may be fixed. FIG. 4 shows a state in which the cover case 20 is in the X ′ direction (as close to the rear as possible) and the Y ′ direction (as close to the boom as possible) within the movable range. By adopting such a position, it is possible to prevent the cover case 20 from being affected as much as possible by the ultrahigh pressure water in the cleaning operation of the construction equipment 1.

  As described above, the construction machine sensor storage device 10 according to the present invention covers the sensor 50 and opens and closes the cover case 20 having an opening in the direction in which the sensor 50 projects a light beam and the opening 25 of the cover case 20. Therefore, according to the construction machine sensor storage device 10, when the construction equipment is cleaned, the opening 25 of the cover case 20 is closed by the lid plate 30. It can be prevented that the ultrahigh pressure water is applied to the sensor and the sensor 50 is damaged.
