JPH0749198Y2 - Heavy object positioning device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a positioning device for positioning a heavy object.

[Prior Art] FIG. 4 and FIG.
Shown in the figure.

In FIG. 4 and FIG. 5, 1 is a bogie main body frame, 2
Is a Y-direction moving frame, 3 is an X-direction moving frame, 4 is a traveling wheel, and 5 is a vertical cylinder.

On the carriage body frame 1, a Y-direction moving frame 2 that can be finely moved in the Y direction shown in the figure is attached via a guide roller 6, and on the Y-direction moving frame 2, X-direction finely moving is possible.
The direction moving frame 3 is attached via a guide roller 7. The X-direction moving frame 3 is equipped with a vertical cylinder 5. With the above combination, positioning in the three-dimensional direction is performed and heavy objects are loaded.

[Problems to be solved by the device]

 The above-mentioned conventional technique has the following problems.

The ground clearance from the ground surface of the dolly to the uppermost vertical cylinder part is inevitably high because of the two-stage mounting of the Y-direction moving frame and the X-direction moving frame on the dolly body,
The height of the entire device cannot be lowered. Therefore, when a target heavy object is mounted, the heavy object must be placed at a high position and can be positioned only at a high position.

An object of the present invention is to provide a heavy object positioning device capable of lowering the level of mounting a target heavy object, that is, reducing the height of the positioning device.

[Means for solving problems]

Minimize the height of the platform for heavy objects (improvement in stability)
As means, the Y-direction moving frame and the X-direction moving frame on the positioning carriage are made into a single frame rather than the conventional two-stage type, and a drive cylinder for driving the frame is also arranged on the same level as the frame. Structure (configuration).

[Action]

By using a single X-direction and Y-direction moving frame arranged on the upper surface of the bogie, the ground clearance becomes lower than that of the conventional structure, and the versatility is expanded.

[Conventional example]

An outline of the configuration of a positioning carriage as one embodiment of the present invention is shown in FIGS.

In FIG. 1, 1 is a bogie body frame, 12 is an XY movement frame, 13 is an outrigger, 4 is a traveling wheel, 5 is a vertical cylinder, 6a and 6b are Y direction adjustment cylinders, 7 is an X direction movement cylinder, 8a and 8b show guide grooves.

In FIG. 1, outriggers 13 and traveling wheels 4 are provided at the four corners.
An XY moving frame 12 having an up / down cylinder 5 vertically movable in the Z direction in the figure is fixedly mounted on the upper surface of the trolley body frame 1 in which the X and Y directions in the figure are slidable. The XY moving frame 12 has a pair of Ys, one end of which is slidably supported in the XX direction by a guide groove 8a provided on the bogie body frame 1 side and the other end of which is pin-coupled to the frame 12.
The direction adjusting cylinders 6a, 6b and one end of the XY moving frame 12 of the Y direction adjusting cylinder 6b are supported so that one end is slidably supported in the YY direction by a guide groove 8b provided on the bogie body frame 1 side. An X-direction moving cylinder 7 is attached to each pin, which is a common point, and the pins are also attached.

2 and 3 show the operating state of the XY moving frame 12 in the drive operation of the drive cylinders 6a, 6b7.

First, the rods of the Y-direction adjusting cylinders 6a and 6b having the driving direction in the YY direction in the figure are moved in and out on average, so that the XY moving frame 12 is slid parallel to the YY direction, and then the XX moving frame is moved. By moving the rod of the X-direction moving cylinder 7 which has a driving direction in the direction, the XY moving frame 12 is moved.
Slide and move in the XX direction.

Further, by changing the outputs of the Y-direction adjusting cylinders 6a and 6b, the XY moving frame 12 can be moved with rotation about the Z axis. During this operation, the Y-direction adjusting cylinders 6a and 6b on the short rod length side follow the movement of the frame 12 to a position uniquely determined so as to follow the guide groove in the XX direction on the long rod length side. Slide through 8.

The above operation is performed to position the XY moving frame 12 at a predetermined position, and then the lifting cylinder 5 is used to lift up a heavy load. The rotational movement about the X axis and the Y axis can be realized by controlling the stroke of each of the four cylinders 5 for up and down, the left and right cylinders, and the front and rear cylinders. Reference numeral 9 in FIG. 3 is an XY slide shoe for supporting the XY moving frame 12 on the trolley body frame 1.

[Effect of device]

The heavy object positioning device according to the present invention includes a movable bogie body frame, an XY movement frame slidably supported on the bogie body frame, and a heavy goods installation installed at four corners of the XY movement frame. Upper and lower cylinders for XY
A pair of Y-direction adjusting cylinders which give movement to the moving frame in the Y direction and which can slide on the carriage body frame in the X direction, and give movement to the XY moving frame in the X direction, and which themselves By having one cylinder for moving in the X direction which is slidable in the Y direction on the carriage body frame, the following effects are produced.

(1) X-axis, Y-axis, Z-axis, around X, around Y,
It can be positioned with six degrees of freedom around Z.

(2) In the conventional two-stage frame type, as the ground height of the dolly becomes higher, the pedestal surface for supporting the weight of the heavy object becomes higher, and it is not possible to position it at a low position. Positioning at a low position is possible, and the level of the entire dolly can be lowered compared to the conventional dolly, and the versatility is expanded, and the pedestal can be lowered and the stability is improved.
