Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a device for erecting induction electrical equipment that has been tipped on its side.

When transporting large induction electrical equipment, such as power transformers and accelerators, they are transported on their sides to avoid dimensional restrictions such as under bridges or inside tunnels.

It is not a particular problem to overturn these devices on their side in a manufacturing factory because large cranes, powerful lifting machines, etc. can be easily used.

However, once these devices have been transported to the installation site, such powerful equipment is not readily available.

Therefore, there is a need for a device that allows these large devices to be properly erected after being transported on their side without using a powerful lifting machine or the like.

Conventionally, a lifting device as described in Japanese Patent Publication No. 52-15772 has been developed as this type of device.

As shown in FIG. 1, this device has a swinging member 2 which has a curved bottom surface on one side of the induction electric device 1 and rotates the induction electric device 1 at the beginning of the lifting stroke of the induction electric device 1. When the first cable 3 pulls the induction electrical equipment 1 in the rotating direction and the second cable 4 moves the center of gravity of the induction electrical equipment 1 away from the end of the swinging member 2, the induction electrical equipment 1 is controlled so that it suddenly stands up straight, and then this restraining force is gradually loosened so that the final stage of the lifting process is completed slowly, but the initial stage of the lifting process and When the center line of the center of gravity of the induction electric device 1 leaves the curved bottom surface of the swinging member 2, slippage occurs in the linear movement backward direction, so this is prevented by the third cable 5 and the fourth cable 6. There is.

As mentioned above, in the conventional lifting device, the swinging member 2
Since the curved bottom surface of the induction electric device 1 can be stepped off before it is properly erected, the erecting operation becomes extremely unstable, causing a safety problem, and the first to fourth cables 3, 4, 5
．． This method has drawbacks such as requiring a four-point operation using a 6-point system, making the work extremely complicated.

This invention was developed to solve the drawbacks of the conventional devices mentioned above, and it has a curved surface that extends from the side to the bottom of the induction electric device, and the upright is installed so that the curved surface is in contact with the ground. A plate, a rolling member that is removably inserted between the curved surface and the ground, and an operation mechanism that moves the rolling member in a rising direction, and rotates and raises the induction electric device through the curved surface. By doing so, it is an object of the present invention to provide a device for erecting induction electric equipment that is easy to work with and has a very stable erecting operation.

Hereinafter, one embodiment of the erecting device for induction electric equipment according to this invention will be described with reference to FIGS. 2 to 7 using a transformer as an example.

In the figure, 11 is a transformer as an induction electric device, 12
are a pair of upright plates, and support surfaces 12C and 12d, which are mutually perpendicular flat surfaces that contact the bottom surface 11a and one side surface 11b of the transformer 11, are formed on the inside, and an arcuate surface 12a is formed on the outside. It is formed.

The upright plate 12 is fixed to the transformer 11 by fastening with bolts and nuts or by welding.

Reference numerals 13 and 14 indicate suspension ears provided on the top of the transformer 11, and 15 indicates a transfer member that is removably inserted between the arcuate surface 12a and the ground. It is composed of rollers 15b that are pivoted to sandwich the upright plate 12 and roll on the ground.

Reference numeral 16 designates a pair of string-like members that respectively connect both ends of the shaft 15 a and the hanging ears 14 via guide pins 12 b on the upright plate 12 , and reference numeral 17 designates a turnbuckle inserted between the string-like members 16 . Adjust the length of the string member 16.

18 and 19 are support stands, G is the center of gravity of the transformer 11, and O is the center of the arc of the arc surface 12a.

Next, the operation of the upright device configured as described above will be explained.

First, since the arc center O is located on the top side of the center of gravity G, the transformer 11 receives a rotational force in the direction of the arrow A, but when the turnbuckle 17 is operated, the string-like member 16 is held in tension and rolls. Since the member 15 acts as a wedge against the arcuate surface 12H, it rests horizontally on the support stand 18.

Next, when the turnbuckle 17 is operated to gradually extend the length of the string member 16, the rolling member 15 is pushed out in the direction of arrow C, and the transformer 11 is moved in the direction of arrow A via the arcuate surface 12a. After gradually rotating and passing through the state shown in FIG. 4, the operation of the turnbuckle 17 is stopped and the standing up is finally completed in the state shown in FIG. 5 due to the wedge action of the rolling member 15. For safety reasons, it is supported by a support stand 19 to stabilize it in an upright position.

The above explanation is for the case where the arc center O is closer to the top than the center of gravity G, but if the arc center O is closer to the bottom than the center of gravity G, the rotational force in the direction of arrow A in the figure does not act from the beginning, so the center of gravity It goes without saying that it is necessary to pull from the hanging lug 13 side until the position of G moves in the direction A from the vertical line passing through the arc center O.

Next, the transformer 11 stabilized in the upright state is jacked up and the upright plate 12 is removed to complete the upright operation.

In the above embodiment, in order to move the rolling member 15 in the upright direction, the hanging lug 14 of the transformer 11 and the rolling member 1 are used.
5 and a turnbuckle 17 inserted therein are used, but of course this is not limiting.

For example, the structure of the rolling member 15 may be changed to the shaft 15.
By making the frictional resistance between a and the roller 15b variable and adjusting it, it is also possible to shift it in the standing direction.

As described above, according to this invention, there is provided an upright plate which has a curved surface extending from the side surface to the bottom surface of the induction electric device and is attached so that the curved surface is in contact with the ground, and a space between the curved surface and the ground. The device is equipped with a rolling member that is inserted in a manner that can be transferred to the robot, and an operating mechanism that moves the rolling member in the upright direction, and by rotating and uprighting the induction electric equipment through the curved surface, the work is easy and It is possible to provide an erecting device for an induction electric device whose erecting operation is extremely stable.
