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 present invention aims to provide an uprighting device that protects the device and improves the workability and safety of materials to be uprighted.

Figures 1 to 3 show a conventional standing up device of this type, in which a material 1 to be raised 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, there are cases where the material to be erected 1 is placed directly on the main body 2 without using the above-mentioned pedestal 3. Furthermore, this pedestal 3 is used as a gate-shaped trolley to move it onto the main body 2 and scoop it up as it is. In some cases.

Reference numeral 9 denotes a connecting link that connects the bearing portion at one end of the main body 2 and the support stand 4 via support shafts 5 and 10, and the support shaft 5 serves as a fulcrum when the main body 2 moves to stand up. Further, a lifting wire 7 is inserted through the lifting hole 2a bored in the free end lifting portion of the main body 2, and by lifting this lifting wire 7 with a crane (not shown), the material to be erected 1 is lifted together with the main body 2. It rotates around the support shaft 5 as a fulcrum for standing up, 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 member 1 to be erected in an erected state.

Thereafter, the lifting wire 7 may be removed from the main body 2 and the material 1 to be erected may be directly lifted and transported to another location, or the assembly work may be performed in the erected state.

Next, even if the main body 2 is further lifted too far by the crane from the normal standing state of the material 1 to be erected, only the connecting link 9 will be connected to the support shaft 1, as shown in FIG.
0 as a fulcrum and tilts by θ°, but since the inclination angle of the main body 2 is small, the material 1 to be erected is unlikely to fall in the direction of arrow A or slide down in the direction of arrow B. As shown in FIG. 2, when the width H of the material to be erected 1 increases, the height of the support base 4 and the height of the jack 8 must be increased as shown in FIG. As the length L of the material 1 to be erected increases, the center of gravity W of the material 1 to be erected becomes higher.
If the distance l between the axes is not made long, the material 1 to be erected will easily fall in the direction of arrow A.

In order to deal with these problems, the support base 4 must be made larger as described above, and the length of the connecting link 9 must be increased, which not only increases the cost of the device itself, but also increases the cost of the device itself. Since the occupied area becomes larger and the height of the member 1 to be erected becomes higher, the workability and safety are extremely poor, and there are drawbacks such as the need for measures against accidents in the event of an earthquake.

This invention was made with attention to this point, and wheels that roll on the floor are pivotally connected to a main body that is rotatably connected to a support base via a connecting link,
It is an object of the present invention to provide an uprighting device that does not require a large supporting stand or the like even when the width and length of a material to be uprighted increases.

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.

Reference numeral 11 denotes a wheel rotatably pivoted to a corner of the approximately L-shaped main body 1 by an axle 12;
contacts the floor surface 6 and rolls only when the main body 1 rotates from lying down to standing up.

Further, as shown in FIG. 4, the connecting link 9 connecting the support base 4 and the bearing portion 2c of the main body 2 has a contact portion 9 with which the protrusion 2b of the main body 2 comes into contact during the standing operation.
a, and a protrusion 9b that abuts on the floor surface 6.
is provided to restrict the upright position of the main body 1.

Since the erecting device of the present invention is constructed as described above, as shown in FIG. Crane the hanging wire 7 (not shown)
When the material to be erected 1 is lifted up by the main body 2, the material 1 to be erected starts to rise together with the main body 2, and at the same time, the wheels 11 roll in contact with the floor surface 6 and guide the main body 2 in the direction of the arrow shown in FIG. From the moment the protrusion 9b of the link 9 contacts the floor 6, it rotates about the support shaft 5 as an upright fulcrum, and as shown in FIG. At the position where it contacts 9a, the material to be erected 1 is erected at right angles, and then the jack 8 is inserted between the lower part of the main body 2 and the floor surface 6 to bring the material 1 to be erected into an erected state. Retained.

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 it is tilted by θ° (Fig. 3),
Since the inclination angle of the main body 2 is extremely small, the material 1 to be erected does not fall or slide as in the conventional case. Note that when the material to be erected 1 is lying down, the connecting link 9 that connects the main body 2 and the support base 4 is in an inclined state. Since l can be made longer than conventional ones, it is not only possible to improve the stability of the material to be erected due to excessive lifting, but also by increasing the distance between the shafts l can reduce the lifting force required by a crane, etc. be.

As described above, according to the present invention, the bearing part at one end of the L-shaped main body and the support base fixed to the floor are connected by a link, and the wheels that roll in contact with the floor are attached to the corners of the main body. This not only makes it possible to significantly reduce the height of the support base 4, but also allows the height of the material to be erected to be maintained even when the width and length of the material to be erected increases. It has an excellent effect of significantly improving workability and safety.
