DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for transporting a long heavy object, and more particularly, to transporting a long heavy object in a state in which the longitudinal direction thereof coincides with the traveling direction of the transport device (hereinafter simply referred to as "vertically long"). Related to the means by which they are made available.

[0002]

2. Description of the Related Art Conventionally, a large forklift or the like is known as a device for transporting a long heavy object such as a machine tool or an electronic component mounting apparatus and having a self-propelled traveling means. As is well known, in this apparatus, a heavy object or a pallet laid under the fork is supported and transported by two forks provided in a cantilever form in front of a vehicle body.

[0003]

However, with such a conventional transfer apparatus, it is difficult to transfer a long heavy object vertically in a case of transferring it in a factory. This is because if the center of gravity of the long heavy object to be conveyed is located forward of the tip of the fork, the long heavy object falls down from the fork, so that the long heavy object must be supported horizontally inevitably. Because there is no. It is also conceivable to extend the fork long in front of the vehicle body to support it vertically, but the fork has a cantilevered shape, so the tip of the fork may bend too much to support a heavy object. . As described above, the conventional means has a problem in that it is difficult to convey a long heavy object in a narrow space in a factory because the object needs to be supported horizontally long in the traveling direction.

[0004] Therefore, an object of the present invention is to provide means capable of conveying a long heavy object vertically in the traveling direction and easily conveying even a narrow space.

[0005]

SUMMARY OF THE INVENTION The present invention provides a cab having traveling means and a distance between the cabs extending from the cab.
A pair of right and left support frame capable integer, and an arm support portion provided vertically movably to each of the pair of left and right supporting <br/> lifting frame, base end portions to each of the arm support of these Plane view of the arm that is pivoted and rotates horizontally
Two arms are provided in a C shape, and these arms are
It was made to be stretchable in the direction.

[0006]

In the above construction, the arm is opened and approached to the support frame side, the traveling means is driven, and the transfer device is moved so that the long heavy object is vertically positioned between the arms.
Then, the arm is closed to approach the long heavy object, and the arm is engaged with the long heavy object. Next, the arm support is raised, and the long heavy object is suspended in the air. Then, the traveling means is driven to convey the long heavy object in a vertically long state.

[0007]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of a long weight, and FIG. 2 is a side view of the same.

Reference numeral 1 denotes a box-shaped operation cab serving as a main body of the transfer device for the long heavy object W, and S denotes a driver space established in the operation cab. Inside the cab 1, a traveling means 20 including a storage battery, a motor, a transmission mechanism, and the like (not shown) is provided.
(See also FIG. 2). 24 is a driven wheel, 2
Reference numeral 3 denotes the shaft, reference numeral 25 denotes a handle, reference numeral 26 denotes running adjustment levers, and reference numeral G denotes a floor surface.

Reference numeral 2 denotes a pair of left and right support frames extending forward from the driver's cab 1. The support frame 2 is slidable in the direction of the arrow a, depending on the width of the long heavy object W. , The distance T between the support frame 2 and the support frame 2 can be adjusted. Reference numeral 3 denotes an arm support provided in front of the support frame 2. The arm support 3 is supported by links 8 and 11 so as to be able to move up and down. The distal end of the link 11 is pivotally attached to the arm support 3 by a pin 13, and the proximal end thereof is pivotally attached to the support frame 2 by a pin 12. A corner of the key-shaped link 8 is pivotally connected to the support frame 2 by a pin 9, an upper end thereof is pivotally connected to the arm support 3 by a pin 10, and a lower end thereof is pivotally connected to a rear end of the rod 7. Is done.

The front end of the rod 7 is connected to the cab 1
Is connected to a rod driving unit 6 provided therein. The rod driving unit 6 is composed of a hydraulic cylinder (not shown) or the like.
The arm support 3 is moved up and down as a result.

Reference numeral 4 denotes an arm having a base end pivotally attached to the arm support 3. This arm 4 has a C-shape in plan view.
2 Kokururu wear is and, Figure 1b direction about the base end portion (water
With a rotatable horizontal direction), FIG c direction (its length
It can expand and contract in the hand direction) . And one of the support frames
Arm 4 on the side of the support frame 2 and the arm 4 on the side of the other support frame 2
Are provided inside the respective support frames 2 so as to face each other. Reference numeral 5 denotes a support claw whose base end is pivotally attached to the distal end of the arm 4.
It is rotatable in the direction.

The present apparatus has the above-described configuration, and the operation will be described next. First, the arm supporting portion 3 is lowered (see the solid line in FIG. 2), and the arm 4 is moved toward the arm supporting portion 3 and is widely opened. And drive the traveling means 20,
Move the transport device along the longitudinal direction of the long heavy object W,
The arm support 3 is positioned so as to sandwich the center of gravity of the long heavy object W.

Next, while adjusting the length of the arm 4, the arm 4 is closed and the supporting claw 5 is rotated, and the claw 5 is engaged with the long heavy object W. Here, this long heavy object W
Need not be placed on a pallet. Then, the rod driving unit 6 is driven to move the rod 7 to the left in FIG.
The arm support 3 is raised to the position indicated by the dashed line, and
In the air. In this state, the traveling means 20 is driven to transport the long heavy object W in a vertically long state.

[0014]

According to the present invention, there is provided a cab having traveling means,
A pair of left and right support frames extending from the driver's cab and having an adjustable distance therebetween, and an arm support portion provided on each of the pair of left and right support frames so as to be vertically movable ,
It is pivotally mounted the base end portion to each of the arm support of these
Two horizontally rotating arms in a C shape when viewed in plan
And extend and retract these arms in the longitudinal direction.
Since the, between the support frame in accordance with the geometry of the long object
While adjusting the spacing of the arm and the opening angle and length of the arm,
Long and heavy objects can be transported vertically in the traveling direction, and can be easily transported even in a narrow space in a factory.
