Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a controller for controlling a crane.

[Conventional technology]

The large-sized crane is provided with an integrated driver's cab on the traveling carriage, and the operator operates the girder from this driver's cab while controlling the traveling of the girder, the traverse of the club, and the lifting and lowering of the hooks.

This operator's cab is located at a position where it is easy to operate the crane, and there is no blind spot in the field of view.

[Problems to be solved by the device]

However, the controller installed in the operator's cab is in a position where a seated operator can visually operate the crane while operating it, but the body shape of the operator varies from person to person. Therefore, if the controller is fixed at a fixed position, it becomes difficult for a person with a large body shape or a person with a small body shape to operate.

It is an object of the present invention to make the position of the controller variable so that the crane operator can easily operate at the most suitable position according to the body shape.

[Means for Solving the Problems]

The present invention has been made in order to achieve the above-mentioned object, and a controller installed in a cab of a crane is slidable in a longitudinal direction by a slide pipe arranged in a lateral direction on the front of the cab. The gist of the present invention is to provide a controller on the bracket via an arm that can bend and stretch.

[Action]

By providing the controller installed in the operator's cab of the crane via a flexible arm on a bracket that is slidable in the longitudinal direction by a slide pipe laterally arranged on the front of the operator's cab, The controller is movable and can be easily and quickly adjusted to its height and lateral position, inclination angle, and front-back position according to the operator's body shape so that the operator can drive the vehicle most easily. This can reduce the labor of the operator.

〔Example〕

 The present invention will be described below based on the illustrated embodiments.

In the figure, reference numeral 1 designates a crane cab, in which slide pipes 2 and 3 are arranged and fixed horizontally along the inner side of the windshield of the cab. These slide pipes 2 and 3 are vertically balanced, and are preferably arranged at positions that do not obstruct the operator's field of view and at a position suitable for supporting the controller, and the ends are bracketed (not shown) or the like. It is fixed on the cab side.

These slide pipes 2 and 3 are slidable and bracket
While fitting 4,5, equipped with screw type fasteners 41, 51 on the boss part of this bracket 4,5, move the bracket 4,5 along the slide pipes 2, 3 Fixture 41,
Tighten 51 so that it can be fixed.

Further, an arm 6 is projectingly provided at the tip of the bracket 4 via a tightenable shaft 42, and the angle of the arm 6 with respect to the bracket 4 can be adjusted by loosening the tightenable shaft 42. The tip is pivotally attached to a part of the controller casing 8, and the other bracket 5 is provided with an anti-vibration type telescopic column 7 at the tip, and the column 7 is locked at the lower end of the controller casing 8. .

Therefore, the controller casing 8 is designated by the column 7 and the arm 6.

In the controller configured as described above, the lateral position adjustment of the controller is performed by the fixing members 41,
This is performed by loosening 51 and sliding it along the slide pipes 2 and 3, stopping it at a position preferred by the operator, and fixing it with fixtures 41 and 51. At this time, the protruding angles of the brackets 4 and 5 should be adjusted. This is done by rotating the brackets 4 and 5 in the circumferential direction along the outer peripheral surface of the slide pipe.

Next, the height position of the controller casing 8 and the distance from the window glass surface are loosened by the tightenable shaft 42, and the arm 6 is bent and extended by this shaft portion to adjust the height and inclination angle to a desired value. By fixing 42, the controller casing 8 is fixed at a desired position.

A second embodiment is shown in FIGS. In the figure, the controller is housed in a controller casing 8, and its configuration is the same as that of the first embodiment. Linear bearings 9, 10, and 11 are arranged on the lower and side surfaces of the controller casing 8, respectively, so that they can be moved vertically and horizontally with respect to a horizontal plane and vertically with respect to a vertical plane. Further, set bolts 12 and 13 are provided for each direction and fixed at predetermined positions.

[Effect of device]

According to the present invention, the height, lateral position and inclination angle of the controller can be arbitrarily changed, so it can be installed according to its body shape at the position where the operator can easily operate, improving the operability of the crane. In addition, there is an advantage that the controller can be easily adjusted.
