Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heavy object reversing device.

(Prior art and its problems) For example, when machining or inspecting various heavy objects such as cylinder blocks for marine engines, large casting molds, bridges, etc., it is necessary to invert such heavy objects. , such work is extremely dangerous. In order to do this safely, various types of reversing devices, such as crane lifting type and stationary type, have been proposed. Among these, as a stationary reversing device, as shown in FIG.
It is rotatably fixed to a base d by a support arm c provided at the rear of the intersection of the two mounting surfaces a and a', and the mounting base b is rotated 90 degrees by a hydraulic cylinder e, etc. There is a method for inverting a heavy object f. However, with this device, the amount of lateral movement of the mounting table during inversion is large, so a large installation space is required.In addition, the center of gravity of the heavy object also moves significantly, which requires a large amount of power, resulting in an increase in the size of the device. Therefore, it has the disadvantage of high cost.

In addition, in order to solve the drawbacks of such conventional devices,
As disclosed in Japanese Utility Model Publication No. 46-2981, an L-shaped mounting table provided with two opposing mounting surfaces at right angles to each other is rotatably supported, and the mounting table is rolled 90 degrees. There is a device that is designed to flip heavy objects over by using the rolling direction, but both this device and the above-mentioned devices can only flip the heavy object 90 degrees in the rolling direction, and cannot flip the heavy object 180 degrees. It is not possible to flip the object so that the desired side is upward. For this reason, these devices require other cargo handling machines such as a crane to perform such reversal, which causes various problems in terms of operation, cost, workability, etc.

The present invention aims to solve the above conventional problems, and will be explained below based on drawings corresponding to embodiments.

(Means for Solving the Problems) The present invention provides an arc-shaped support member 4 on the rear side of a mounting table 3 provided with two opposing mounting surfaces 1 and 2 at right angles to each other, and the arc-shaped support The member 4 is rotatably supported by a support roller 6 provided on a base 5, and
A driving means D for driving the arc-shaped support member 4 in the rolling direction is provided at a suitable location, and the two mounting surfaces 1,
2, for example, in the case of the illustrated embodiment, the mounting surface 2 is provided with a rotating table 10 that can move forward and backward relative to the mounting surface 1 on the other side. be. Here, the two mounting surfaces 1 and 2 may have an appropriate shape such as a planar shape or a slatted shape. Further, the support rollers 6 are required to be installed at at least two locations along the arc-shaped support member 4, but they may be supported by a plurality or a large number of support rollers (not shown). Of course. Furthermore, if the driving means D is configured to drive the arcuate support member 4 in the rolling direction, it may include a driven joint 7 such as a roller chain or a gear provided along the arcuate support member 4;
In addition to the drive wheel 8 such as a sprocket or gear provided on the base 5, any other suitable mechanism may be used. Incidentally, the drive means D is connected to the driven joint 7 in this way.
and a driving wheel 8, the driving wheel 8
If it is arranged coaxially with the support roller 6 as shown in the figure, there is an effect that even if the arc-shaped support member 4 is not a perfect arc and is distorted, the drive can be performed reliably. However, such a coaxial configuration is not essential. Further, the forward/backward movement mechanism and turning mechanism of the turning table 10 may be any suitable one.

(Function) In such a configuration, the present invention is applied, for example, when the mounting surface 1 on one side is in a horizontal state and the mounting surface 2 on the other side is in an upright state, for example, as shown in FIG. 2b. Then, the heavy object 9 to be turned over is placed on the horizontal loading surface 1 using an appropriate cargo handling machine such as a crane. At this time, it is preferable that the surface of the heavy object 9 on the placement surface 2 side be brought into contact with or close to the turning table 10.

In this state, when the arcuate support member 4 is driven by the drive means D, the arcuate support member 4 rolls while being supported by the support rollers 6. Therefore, the mounting table 3 also rolls at the same time, and the mounting surface 1 gradually inclines, the inclination of the mounting surface 2 gradually becomes gentler, and the heavy object 9 is also gradually turned over. In this way, as shown in FIG.
Stops driving. In this way, the present invention removes the heavy object 9 from its original state, similar to the conventional device described above.
It can be inverted 90 degrees and supported on the rotating table 10 on the mounting surface 2. In this state, the heavy object 9 can be transferred to an appropriate work place by a cargo handling machine, and then in the state inverted 90 degrees. It is possible to carry out machining, inspection, etc.

Next, the heavy object 9 is first placed on the mounting surface 1 (FIG. 4a), turned over 90 degrees as described above, and supported on the rotating table 10 (FIG. 4b). By turning the heavy object 9 by 180 degrees onto the placing surface 2 using the turning table 10 (Fig. 4 c→d) and turning it over again by 90 degrees in the opposite direction (Fig. 4 e), the cargo handling machine can be rotated. Just use the reversing device without using it
Can perform 180 degree flips. Further, by performing such a 90 degree inversion with the rotation angle of the turning table 10 at an angle other than 180 degrees, it is possible to invert the heavy object 9 so that the desired surface is the upper side. In this way, it is sufficient to configure the turning table 10 on either one of the two mounting surfaces 1 and 2, but operability may be improved depending on the application if it is configured on both sides. be able to. The turning table 10 is configured to be able to move forward and backward with respect to the mounting surface 1 on the other side, so that when rotating the heavy object 9, the heavy object 9 is prevented from colliding with the mounting surface 1 on the other side. It can be prevented.

(Effect of the invention) As described above, the present invention provides two
An arc-shaped support member is provided on the rear side of the mounting table provided with two mounting surfaces, and the arc-shaped support member is supported by a support roller provided on the base. Since it is rotated 90 degrees by rolling, the horizontal movement of the mounting table during such rotation is extremely small, so the required horizontal installation space is small, and the weight is reduced when the table is turned over. Since the movement of the center of gravity of the object can be minimized, the power required for reversing is also small, and the device as a whole can be downsized, resulting in a significant reduction in cost. In particular, the present invention
Since at least one of the two mounting surfaces is provided with a turning table that can move forward and backward with respect to the other mounting surface, the above-mentioned 90 degree rotation of the mounting surface,
By combining the rotation with a rotating table, it is possible to not only flip heavy objects 180 degrees, but also flip them with the desired side facing upwards without the need for other cargo handling equipment, making it possible to machine, inspect, etc. these surfaces. It has the special effect of being able to do this efficiently. still,
Of course, the present invention can be used not only for reversing heavy objects, but also for machining or inspection while placed on the above-mentioned placement surface. Further, the base may be fixedly installed on the ground, or may be movable by an appropriate mechanism as the case may be.
