Description

DETAILED DESCRIPTION OF THE INVENTION The present 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 actuators, they must be collapsed before being transported under bridges, inside tunnels, etc. due to size restrictions.

There is no particular problem in tearing down these devices at the manufacturing factory, as large cranes, powerful lifting machines, etc. can be easily used. However, once these devices are shipped to the distribution site, such powerful equipment is not readily available. Therefore, there is a need for a device that allows these large devices to be erected normally after being transported on their side without using a powerful hot water machine. Conventionally, this type of device
A raising device such as that described in Japanese Patent No. 772 has been developed.

As shown in FIG. 1, this device is provided with a swinging member 2 having a curved bottom surface on one side of an induction electric device 1 and rotating the induction electric device at the beginning of the lifting stroke of the transfer electric device 1. When the first cable 3 pulls the induction electrical equipment 1 in the direction of rotation and the second cable 4 moves the center line of the center of gravity of the induction electrical equipment 1 away from the end of the swinging member 2, the induction electrical equipment 1 This system controls the sudden standing upright of the robot, and then gradually loosens this restraining force to gently complete the final stage of the raising process. After each linear movement when the center line of weight b of 1 leaves the curved bottom surface of swinging member 2,
Since rearward slippage occurs, this is prevented by the third cable 5 and the fourth cable 6'. As described above, in the conventional lifting device, the curved bottom surface of the swinging member 2 is cut off before the induction electric device 1 is properly erected, making the lifting operation very unstable, which poses a safety problem. occurs, and the first and fourth cables 1, 2, and 3
, 4 requires four-point operation, which has the disadvantage of making the work extremely complicated.

This invention was made to eliminate the drawbacks of the above-mentioned conventional devices, and has a curved surface extending from the side to the bottom of the induction electric device, and is mounted so that the curved surface is in contact with the ground. The device is equipped with horizontal and vertical jacks built into the upright board and the upright board, and a mechanism for sliding the electrical equipment in the horizontal and vertical directions using the jacks. The purpose of the present invention is to provide an extremely stable erecting device for induction electric equipment by moving the center of gravity so as to rotate and erect the induction electric equipment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the erecting device for induction electric equipment according to the present invention will be described below with reference to FIGS. 2 to 6 using a transformer as an example.

In the figure, 11 is a transformer as an induction electric device, 12
13 is a reinforcing member for the transformer 11, which is fixed to the transformer 11 by fastening with bolts and nuts.

Reference numeral 14 denotes a vertical jack when the transformer 11 is in the upright state, and one end is fixed to the upright plate 12 by fastening with screws.

Reference numerals 15 and 16 refer to guide plates that can be slid in the horizontal direction and pulled in the vertical direction when the transformer 11 is in an upright state, and as shown in FIG. 6, the other end of the jack 14 and the guide plate 15 are connected by screws. The guide plate 16 and the reinforcement 13 of the transformer are fixed by fastening or the like, and the guide plates 15 and 16 are fixed by fastening with screws 20 or the like, so that the guide plates 15 and 16 can be moved on the anti-friction surface 21.

Reference numeral 17 denotes a horizontal jack when the transformer 11 is in an upright state, and as shown in FIG. 6, one end is fixed to the upright plate 12 by screws or the like.

18 and 19 are guide plates that can slide in the vertical direction when the transformer 11 is in an upright state, and can be pulled and pushed in the horizontal direction, and the end of the jack 17 and the guide plate 18 are fixed by fastening with screws, etc. The guide plate 19 and the reinforcing member 13 of the transformer are fixed to each other by fastening screws 201 or the like.

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

As shown in FIG. 3, the transformer 11 which has been laid down on its side is kept in a position where the center of gravity G is at the center of the circular arc, so that the upright device located on the top side holds the transformer 11 lying on its side and stops. First, the jack 14 is operated to the retracting side (in the direction of arrow B). Since one end of the jack 14 is fixed to the upright plate 12, the guide plates 15, 16, the transformer reinforcement 13, the transformer 11, and the guide plate 19 move in the direction of arrow B. As the transformer 11 moves toward the bottom, the center of gravity G also begins to move in the direction of arrow B. Until the center of gravity G reaches the arc center 0, it remains lying on its side, but
If the center of gravity G moves to the lower side of the arc center ○, the transformer 11
etc., are transferred along the arc surface 12a and begin to become independent. FIG. 4 shows a state in which the jack 14 has been completely retracted and is in the middle of being raised. Next, the jack 17 is operated toward the extrusion side (in the direction of arrow A). Since one end of the jack 17 is fixed to the upright plate 12, the guide plates 18, 19, the transformer reinforcement 13, the transformer 11, and the guide plate 16 move in the direction of arrow A. As the transformer 11 moves in the direction of arrow A, the center of gravity G also moves in the direction of arrow A, and the transformer 11 further rolls along the arcuate surface 12a and continues to stand on its own. FIG. 5 shows the upright position. Next, the transformer 11 that has been stabilized in an upright state is jacked up, and the upright plate 12 and the like are removed to complete the upright operation. As described above, according to the present invention, an upright plate having a curved surface extending from the side surface to the bottom surface of an induction electric device is attached so that the curved surface is in contact with the ground, and the It is designed to be erected manually, and does not require a large crane or the like, and is easy to work with.
By arbitrarily selecting the desired value through the operation of , it is possible to easily control the standing operation of the transfer electric equipment, which has a great practical effect.
