Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an erecting device for erecting a large and heavy material to be erected, such as a transformer core, at a substantially right angle. The purpose of this invention is to provide an elevating device that protects equipment and simplifies crane operation.

Figures 1 to 3 show a conventional standing up device of this type, in which a material to be raised 1 is first placed on an approximately L-shaped main body 2 via a pedestal 3, as shown in Figure 1. However, the pedestal 3 is fixed to the main body 2 by appropriate means so that it does not fall off when the main body 2 is stood up. In addition, as shown in FIG. 1, the main body 2 has its bottom surface 2c in contact with the floor surface 6 when lying down, and uses a support shaft 5, which has one end rotatably pivoted to the support base 4, as a fulcrum for standing up. It is configured to rotate within a predetermined angle, that is, a range of 90 degrees.

Furthermore, a lifting wire 7 is inserted into a hanging hole 2a bored at the free end of the main body 2, and by lifting this lifting wire 7 with a crane (not shown), the material to be erected 1 is supported together with the main body 2. It rotates about the shaft 5 as a fulcrum and stands up at right angles as shown in FIG. Thereafter, a jack 8 is inserted between the lower part of the main body 2 and the floor surface 6 to hold the material 1 to be erected in an erected state.

Since this type of conventional erecting device is constructed as described above, the main body 2 is further lifted up by a crane from the normal erected state of the material 1 to be erected as shown in FIG. 2, as shown in FIG. If the main body 2 is lifted too much and it becomes tilted by θ°, the material 1 to be erected will fall in the direction of arrow A or slide down in the direction of arrow B, which is not only extremely dangerous. However, there is a drawback that the lifting operation of the main body 2 by a crane requires extremely skill.

This invention has been made with attention to this point, and by connecting the main body and the support stand rotatably to each other via a connecting link, and using a plurality of fulcrums for standing up when the main body is lifted. The object of the present invention is to provide an erecting device in which the inclination angle of the main body is made small to prevent the material 1 to be erected from falling or slipping.

That is, although FIGS. 4 to 6 all show one embodiment of the present invention, the same reference numerals as those in the above-mentioned conventional system (FIGS. 1 to 3) refer to the same constituent members and their explanations will be explained. Omitted.

9 is a bearing 2d provided at the back end of the short side of the main body 2.
and a bearing part 4b provided on the rear side of the upper surface of the support base 4 are connected to each other via the support shafts 5 and 10 in a single connecting link of a predetermined length rotatably.
Needless to say, 10 serves as a fulcrum for raising the main body 2. Further, as shown in FIG. 5, the connecting link 9 has a contact portion 9a that contacts the projection 2b of the main body 2 during the standing operation, and a projection 9b that contacts the contact portion 4a of the support base 4. These protrusions 2b, 9b and contact portions 4a,
9a is provided to restrict the upright position of the main body.

Now, as shown in FIG. 4, after the material 1 to be erected is placed on the main body 2 via the pedestal 3, the lifting wire 7 is lifted by a crane (not shown). The material to be erected 1 is attached to the support shaft 5 along with the main body 2.
As shown in Fig. 5,
The material to be erected 1 is erected at right angles at the position where the protrusion 2b abuts the abutting portion 9a of the connecting link 9. After that, a jack 8 is interposed between the lower part of the main body 2 and the floor 6. The material 1 to be erected is held in the erected state.

Next, even if the main body 2 is further hoisted by the crane from the normal upright state of the material 1 shown in FIG. Although the main body 2 moves and tilts by "θ°", the main body 2 hardly tilts, so the material 1 to be erected does not fall or slide down as in the conventional case.

It goes without saying that the inclination angle "θ°" of the connecting link 9 is determined by the distance l between the two support shafts 5 and 10.

As described above, according to the present invention, approximately L
A bearing portion 2d provided at one end of the main body 2 forming a letter shape.
and the bearing part 4b of the support base 4 are connected by a connecting link 9, so that the main body 2 is rotated by one lifting operation using the support shaft 5 as a fulcrum, and the upright device is established. . In addition, if the wire 7 is lifted too high, the support shaft 10 serves as a fulcrum, so the main body 2 hardly tilts, which not only prevents the material 1 to be erected from falling or slipping, but also Since the main body 2 may be lifted up a little too much, it also has the effect that no skill is required to operate the crane.

Claims (1)

[Claims] 1 Approximately L having a mounting surface on which the material to be erected is placed, and a hanging hole provided at one end to be lifted during the erecting operation.
A main body forming a letter shape, provided at the other end of this main body,
