Description

[Detailed Description of the Invention] The present invention relates to a device for handling one load using two overhead cranes.

For heavy loads or large-sized loads, use the coupler 10A as shown in Figure 1.
The two overhead cranes A and B are used together to handle cargo.

During cargo handling work, as shown in Figures 1 and 2, the hanging re-beam 9A is hung by the respective hanging tools 13A and 13B of the two overhead cranes A and B, and one load is hooked onto the hanging beam 9A. I will do it.

Each overhead crane A used for such co-suspension work,
B is a hoisting rope 1 hung on hanging tools 13A and 13B conventionally.
Hoisting drum 6A for vertically operating 4A, 14B,
6B was provided on the trolleys 2A, 2B in a direction perpendicular to the main girders IA, 1B.

Therefore, the interval dimension X between the hanging tools 13A, 13B suspended by the suspension ropes 14A, 14B increases, and the length of the suspension beam 9A also increases.

In addition, the width dimension Z of overhead cranes A and H also increases.

In order to reduce each dimension X, Z, the hoisting drums 6A, 6B
One idea would be to make the diameter larger and shorten the length, but in such a case, the height dimension H of the overhead cranes A and B would increase by the increased diameter.

An increase in each of these dimensions X, Z, and H results in the disadvantage that the building in which the overhead cranes A and B are installed must be enlarged.

The purpose of the present invention is to reduce the space required for co-hanging work equipment and to improve the efficiency of cargo handling work.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 8.

Each overhead crane C and D use coupler 10 when working together.
It is considered as one body.

The trolleys 2 of each overhead crane C and D move laterally on the traverse rail 4 on the main girder 1.

A hoisting drum 6 is installed on the trolley 2 in a posture parallel to the span E direction.

A hoisting rope 14 is let out from the hoisting drum 6, and a fourth
As shown in the figure, the hoisting rope 14 passes through the head sheep 17 and the equalizing sheep 16 on the trolley 2 and is hung around the hanging tool 13.

The hoisting drum 6 is rotated by a motor 32 on the trolley 2 via a speed reducer 7, and the hoisting rope 14 is reeled in and let out to move the hoist 13 up and down.

The trolley 2 can traverse up to the area indicated by the two-dot chain line in FIG. 1 by driving the wheels 22 by the motor 34 on the trolley 2 via the speed reducer 36.

As shown in FIGS. 4 and 5, the auxiliary hoisting device moves the auxiliary trolley 3 to each rail 5, 29 of the outer main girder 1 with a wheel 22. 3
0, and an auxiliary hoisting drum 8 is provided on this trolley 3 in a posture parallel to the span E direction.

An auxiliary hoisting rope 45 hangs down from the auxiliary hoisting drum 8, and suspends the auxiliary hoisting tool 20.

The auxiliary hoisting drum 8 is also driven by the same means as described above, and the catching trolley 3 can also be moved laterally to the area indicated by the two-dot chain line in FIG. 3 by the same means as described above.

The suspension beam 9 is lifted by each lifting device 13 of each overhead crane C, D.

At the center of this hanging beam 9, a means 15 for securing the load is provided.

According to the above embodiment, since the hoisting drum 6 is not long in the direction perpendicular to the span E direction, each overhead crane C, D
The distance between each main girder supporting the trolleys 2 can be reduced.

Therefore, the widthwise dimensions of each of the overhead cranes C and D are reduced.

Furthermore, since the interval X between the hanging tools 13 of each overhead crane C and D is also reduced, the hanging beam 9 becomes smaller.

When reducing these dimensions, the diameter of the hoisting drum 6 is not increased, so there is no increase in the height H of each overhead crane C, D.

If the auxiliary hoisting device is installed in the arrangement shown in Figure 4 by taking advantage of the reduction in the widthwise dimension of each overhead crane C and D, the handling range Y of light objects by the auxiliary hoisting device can be made very wide. Therefore, long objects that exceed the cargo handling range Y may be suspended together by the auxiliary hoisting devices on both sides, or the lifting devices 13 and 20 are located far apart, so cargo handling operations must be carried out independently of each other. This also brings about advantages such as being able to improve efficiency by having cargo handling work that matches the cargo role.

As described above, according to the present invention, by using overhead cranes in parallel during co-hanging work, the large required width dimension can be reduced as much as possible without increasing the height dimension, and the auxiliary hoisting device of the auxiliary hoisting device This provides the effect of efficiently performing co-hanging cargo handling work by ensuring as wide an interval as possible and having a configuration that is useful for co-hanging cargo handling of long objects.
