Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a device for attaching an operation panel such as an operation control panel of various equipment to a fixed frame such as a main body of the equipment.

(Conventional technology) In order to reduce the burden of fatigue on the operator on an operation panel where the operator is engaged in monitoring or operation work for a relatively long period of time, the operation panel should be adjusted to suit the operator's sitting height and overall body length. It is desirable to install it at an appropriate height.

(Problem that the invention aims to solve) However, because the conventional operation panel is fixed to a fixed frame with bolts etc. according to the average sitting height and height of the operator, short operators Operators are forced to take an awkward position with their heads facing upwards, and tall operators are forced to hunches their backs and face downwards. Therefore, the purpose of the present invention is to create an operating panel that can select the optimal installation height corresponding to the operator's height, and that will prevent the operating panel from detaching from the rotating body and popping out unexpectedly due to human error. Another object of the present invention is to provide a mounting device.

(Means for Solving the Problems) Hereinafter, using the reference numerals in the attached drawings, the operation panel mounting device of the present invention will be described.

The hydraulic cylinder 9 is pivotally connected, and the base end 14a is pivotally connected to the distal end of the plunger 12 or the main body base end 9a with the horizontal pivot 11, and the intermediate part 14b is connected to the horizontal pivot 16.
a hook plate 14 pivotally connected to the rotating body 1;
It is attached to the operation panel 5 and consists of a pin 1 that engages and disengages from the tip end hook portion 14c of the hook plate 14.

(Embodiment) In the illustrated embodiment, a rotating body 1 made of a plate material is bent so as to receive an operation panel 5, and forms a biaxial hinge together with horizontal pivots 2 and 4. That is,
The base end portion 1a is divided into a plurality of cylindrical portions, a movable cylindrical body 1c is inserted between the cylindrical portions, and the horizontal pivot 2 is fitted into the cylindrical portion and the movable cylindrical body 1c. 1
c is welded and fixed to the projecting portion 3a of the fixed frame 3. Further, the tip portion 1b is also divided into a plurality of cylindrical portions, and a movable cylindrical body 1d is inserted between the cylindrical portions.
The horizontal pivot 4 is fitted into the cylinder portion and the movable cylinder body 1d,
The movable cylinder 1d is located at the lower end 5a of the back surface of the operation panel 5.
It is welded and fixed.

The stay 6 is composed of a bifold type stay with a stopper connected by a pivot 13, and is arranged so that the pivot 13 is parallel to the horizontal pivot 2, etc., and the base end 6a is connected to the upper surface of the rotating body 1. The upper end portion 6b is pivotally attached to the middle portion of the side surface of the operation panel 4.

The fluid cylinder 9 is constituted by a hydraulic cylinder, and the tip of the plunger 12 is connected to the side wall 3 of the fixed frame 3.
b, and the base end portion 9a of the main body is pivotally connected to the middle portion of the lower surface of the rotating body 1. Note that an air cylinder can also be used as the fluid cylinder 9, and is not particularly limited. In addition, the base end of the main body is fixed to the side wall 3 of the frame 3.
b, and the tip of the plunger may be pivoted to the middle part of the lower surface of the rotating body 1. As stay 6,
A telescoping stay can also be used and is not particularly limited.

Further, in the illustrated embodiment, a case 19 fixed to the upper end 5b of the operation panel 5, a receiver 20 provided on the rotating body 1, and a movable handle 21 inserted into the case 19 so as to be linearly slidable. , a latch 22 pivotally attached to the case 19 and engaging and disengaging from the receiver 20;
A handle consisting of an operating link 23 which is pivotally attached to the case 19 and whose one end is connected to the inner end of the movable handle 21, and a spring 24 which biases the latch 22 to rotate in the direction of engagement and retention with the receiver 20. Equipped with a device, the latch 22 can be opened by the straight drawer of the movable handle 21.
is rotated to release the engagement between the latch 22 and the receiver 20.

(Function) In the state shown in Fig. 4, the fluid pressure cylinder 9
The plunger 12 of is operated most backward into the main body,
The operation panel 5 is set at the lowest position.
The hook plate 14 engages with a pin 18 attached to the operation panel 5. The flow of fluid pressure into and out of the fluid pressure cylinder 9 is blocked by a suitable valve device, and the operation panel 5 is held fixed at the position.

Here, when the plunger 12 of the fluid pressure cylinder 9 is operated to protrude by operating the valve device, the rotating body 1 rotates upward about the horizontal axis.

At this time, the hook plate 14 is urged to rotate in a counterclockwise direction about the horizontal pivot 16, that is, in a direction in which the end hook portion 14c of the hook plate and the pin 18 are more firmly engaged. Therefore, at this stage, the operation panel 5 is firmly fixed to the rotating body 1.

Further, as the plunger 12 continues to project, the horizontal pivots 10, 11, and 16 are aligned in a straight line, and from this point on, the tip hook portion 14c of the hook plate 14 and the pin 18 begin to separate. and,
When the protruding operation is performed to the maximum extent, the engagement between the hook plate 14 and the pin is completely automatically released as shown in FIG.

Then, pull the movable handle 21 of the handle device to disengage the receiver 20 and the latch 22,
The operation panel 5 is unlocked from the rotating body 1. When the movable handle 21 is further pulled to open the stay 6, the operation panel 5 rotates upward about the horizontal pivot 4, rises diagonally from the upper surface of the rotating body 1, and is set at the highest position. The state shown in FIGS. 1 and 2 is reached.

At this stage, the hydraulic cylinder 9 is locked again by the valve device, and the operation panel 5 is fixedly held in this position. A similar process is followed when operating the operation panel 5 from a high position to a low position, and the hook plate 14 and pin 18 automatically shift from the disengaged state to the engaged state.

By changing the retraction distance of the plunger 12 of the fluid cylinder 9, the operation panel 5 can be set to an arbitrary height position between the highest position shown in FIG. 2 and the lowest position shown in FIG. be done.

(Effects of the invention) As described above, according to the mounting device of the invention, the operation panel 5 can be easily installed at the optimum height position corresponding to the sitting height and whole body length of the operator, so that it can be used for various equipment operation tasks. Monitoring work, etc. can be performed with less fatigue and burden.

In addition, when the operation panel 5 is in a low position, such as when the operation panel 5 is housed in a panel storage section on the front of the device, the hook plate 14 and pin 18 are further strengthened as the rotating body 1 moves in the opening direction. Since the engaging force is applied, the operation panel 5 is firmly fixed to the rotating body 1. Therefore, there is no risk of the operation panel 5 detaching from the rotating body 1 and popping out unexpectedly due to human error.
