Description

[Detailed explanation of the idea] The present invention relates to a heavy object reversing device.

For example, when machining or inspecting cylinder blocks of marine engines, large casting molds, bridges, and other heavy objects, it is necessary to turn the heavy objects over.
Such work is extremely dangerous.

In order to do this safely, various reversing devices such as crane-suspended type and stationary type have been proposed.

In this invention, a reversing unit that can freely drive a reversing loop is installed on the left and right sides of a lifting rod that is suspended by a crane via a lifting wire, and by driving the reversing loop, a heavy object is supported in the air. In particular, the present invention is capable of reversing a heavy object to be reversed by extremely rationally attaching the reversing unit to the suspension rod and suspending the suspension rod using the suspension wire. This reduces the required strength of the suspension rod relative to the rated weight and improves operability.

The present invention will be described in detail below based on examples.

Reference numeral 1 denotes a reversing unit in which a reversing /L and -p 2 are suspended and supported so as to be freely drivable.

The reversing loop 2 may be constructed of an appropriate flexible section, such as a wire rope, a nylon sling, or a link chain, depending on the heavy object 3 to be reversed.

Further, the mechanism for driving the reversing loop 2 may be any suitable mechanism such as a mechanism in which the drive wheel 4 is rotated by an electric motor 5 via a suitable speed reduction mechanism.

A moving roller 6 is mounted on the top of the reversing unit 1 configured as described above.
A fitting part 7 is constructed.

In the figure, the fitting part 7 is composed of side plates 8, 8 protruding from the upper part of the reversing unit 1 and the moving roller 6, but if a hanging rod 9 described later can be freely inserted therein. It may be used as appropriate, such as configuring the upper plate.

It may be configured as appropriate, such as by providing a plurality of twisted guide rollers 6.

By fitting the suspension rod 9 into the fitting portion 1, the pair of reversing units 1 are attached to the left and right sides of the suspension rod 9.

The reversing unit 1 can be easily moved by the moving rollers 6.

Here, a plurality of fitting holes 10° 10, 10, . . . are formed in the side portion of the suspension rod 9 in the length direction, and
Bosses 11 corresponding to the fitting holes 10 are provided on both sides of the fitting portion 7, that is, on the side plates 8, 8 in the figure.

The boss 11 is formed to protrude outward, and the protrusion itself is
This is the winding part 13 of the hanging wire 12.

For example, the winding portion 13 may have a smaller diameter on the tip side and may be provided with a brim-like wire stopper plate 14 at the tip, or the wire stopper plate 14 may be used as a rotatable rotating plate as shown in FIG. An appropriate mechanism for preventing the wire from coming off may be provided, such as a wire preventing rod 15 protruding from the rotating plate to the outside of the winding portion 13.

! Alternatively, the winding portion 13 may not be provided with such a mechanism, and the wire retaining rod 15 may be provided protruding from a flange-like plate 17 at the end of the connecting pin 18, as shown in FIG. good.

To summarize the above, as long as the boss 11 is formed to protrude outward and the protrusion itself is used as the winding part 13 for the hanging wire 12, the mechanism for preventing the wire from coming off can be constructed as appropriate. It's good.

Reference numeral 18 is a connecting pin that can be fitted into the fitting hole 10 and the boss 11, and 19 is a member that prevents the connecting pin 18 from being removed.
20 is a handle.

In such a configuration, the heavy object reversing device of the present invention allows the reversing units 1, 1 to rotate the heavy object 3 to be reversed by fitting the connecting pin 18 between the bosses 11 and 11 through the fitting hole 10. It is fixed at appropriate positions on both the left and right sides of the suspension rod 9 depending on the size, and the suspension wire 12 wound around the bosses 11 and 11 is used by being wound around the hook 21 of the crane in an appropriate manner.

In this state, the moving roller 6 is free.

In order to turn over the heavy object 3, after wrapping the reversing loop 2 around both sides of the heavy object 30 placed on the ground,
Lift the hook 21 and lift the suspension rod 9 via the suspension wire 12, thereby moving the heavy object 3 into the reversing loop 2.
to support in the air.

In such a state, the heavy object 3 can be reversed by driving the reversing loop 2, and then the hook 21
By lowering , the heavy object 3 can be placed on the ground in an inverted state.

As described above, the present invention reverses the heavy object 3 while supporting it in the air by driving the reversing loop 2, so that the work of reversing the heavy object 3, which was conventionally very dangerous, can be carried out safely.

In particular, the major features of the present invention are the attachment of the reversing unit 1 and the suspension rod 9, and the suspension configuration of the suspension rod 9 by the suspension wire 12.

That is, as described above, the present invention includes the reversing unit 1 and the suspension rod 9.
The connecting pin 18 that connects and fixes the
0 and fits between the bosses 1111 formed on both sides of the insertion part 70 of the reversing unit 1.
1° 11 is formed to protrude outward and the protrusion itself serves as the winding part 13 of the hanging wire 12, so that the point of action of the gravity of the heavy object 3 applied via the reversing loop 2 and the hanging wire 12 are The point of action of the lifting force applied through the lifting wire 12 coincides with the point of action of the lifting force applied through the lifting rod 12, and therefore, only a compressive force is applied to the lifting rod 9, and no bending moment is generated. The required strength of the suspension rod 9 can be reduced.

This not only reduces the cost, but also reduces the weight of the reversing device, which has the great feature of reducing the load on the crane used in the reversing device of the present invention.

Further, the reversing device of the present invention adjusts the mounting position of the reversing unit 1 with respect to the suspension rod 9 by inserting and removing the connecting pin 18 according to the dimensions of the heavy object 3 to be reversed. Since the moving roller 6 is provided, the reversing unit 1 can be easily moved during such adjustment.
Moreover, the hanging wire 12 is wound around the boss 11.
Since it can move together with the reversing unit 1, it has the great feature that it can be adjusted with light effort even in the case of a large model in which the weight of the hanging wire 120 is considerable.

As described above, the present invention allows the installation of the reversing unit and the lifting rod, as well as the lifting of the lifting rod using the lifting wire, in an extremely rational manner, so that the lifting of the heavy object to be reversed is possible with respect to the rated weight. Not only can the required strength of the lifting rod be reduced, but also the load on the crane that suspends the lifting rod can be reduced, and the installation position of the reversing unit can be adjusted according to the size of the heavy object with extremely simple operation, reducing labor. It has the great feature that it can be carried out using
