[Problems to be solved by the invention]
However, the roller drawing operation shown in FIG. 7 has a risk factor such as the roller coming off, is not safe, and requires a large number of workers, and therefore has a low work efficiency.
[0015]
Although the method using the portal jig shown in FIG. 8 is safe, there is a case where it cannot be transported to a place with a narrow entrance such as an electric room that cannot be used because the use space is wide and workability is poor. In addition, there is a form in which the control panel is inclined or laid down for a site with a narrow frontage. In this case, in order to lift and tilt the control panel, a balancer accompanying the movement of the center of gravity is required, and the apparatus itself becomes large. Also, the weight of the apparatus increases, and it becomes a problem to carry the apparatus itself to a narrow site or high place.

In addition, the safety pin 34C is connected to the carriage 10 or the like by a chain or the like (not shown) to prevent loss.
[0029]
Next, with reference to FIGS. 3 and 4 together with FIGS. 1 and 2, a method of transporting the control panel using the transport device of the present embodiment will be described.
[0030]
As shown in FIG. 3, the onboard crane 101 of the truck 100 lowers the control panel 200 from the loading platform 102 to, for example, a floor 300 close to the electrical room, and removes the fall prevention fittings 201 attached to both sides of the control panel 200.
[0031]
Next, in the control panel 200, the touchment 40 is attached to both sides of the control panel 200 in place of the fall prevention metal fitting 201.
[0032]
Next, as shown in FIG. 4, the operators 401 and 402 bring the two transfer devices (the transfer devices 501 and 502) shown in FIGS. 1 and 2 closer to the control panel 200.
[0033]
Next, the operators 401 and 402 adjust the vehicle width variable mechanism 20 of the transfer devices 501 and 502 according to the entrance of the electric room or the like into which the control panel 200 is carried, and the distance between the changed wheels. Is fixed with a fixing tool 25.
[0034]
Next, the operators 401 and 402 put the support fittings 34 of the transfer devices 501 and 502 below the attachment 40, position the drop-off prevention protrusions 34 </ b> A of the support fitting 34 in the holes 41 of the attachment 40, and the hydraulic jack 33. The operation lever 33C is operated to slightly jack up, and the drop-off preventing projection 34A of the support bracket 34 is exposed from the hole 41 of the attachment 40. Then, the safety pin 34C is inserted into the hole 34B of the drop prevention protrusion 34A. Thus, the control panel 200 is supported from both sides by the transfer devices 401 and 402.
[0035]
Next, the operators 401 and 402 operate the operation lever 33C of the hydraulic jack 33 to lift the control panel 200 to a height at which the control panel 200 is separated from the floor 300 and does not interfere with the obstacle being transported. Transport to an electrical room etc. to the installation position.
[0036]
Next, the operators 401 and 402 remove the safety pin 34C from the hole 34B of the drop prevention protrusion 34A, and then operate the cock of the hydraulic jack 33 to release the lifting operation. As a result, the control panel 200 can be lowered by its own weight and the pulling force of the spring mechanism 35, and the control panel 200 can be fixed to the floor 300.
[0037]
Next, the operators 401 and 402 separate the transfer devices 501 and 502 from the attachment 40 of the control panel 200, and remove the attachment 40 from the control panel 200, thereby completing a series of transfer operations.

Even when the attachment position of the attachment 40 attached to the control panel 200 is low, it is possible to safely leave and land without requiring temporary work such as tilting the control panel 200 to float.
[0040]
Further, according to the transport device of the present embodiment, the vehicle width varying mechanism 20 is provided with the scale 23, so that the insertion amount of the movable pipe 22 on one side or both sides with respect to the fixed pipe 21 can be defined and fixed. A hole 24 is formed in the pipe 21, and the vehicle width can be fixed by inserting or screwing the fixing tool 25 into the hole 24, so that a balance can be ensured during conveyance and the operation can be performed stably.
[0041]
Furthermore, according to the transport device of the present embodiment, the large-diameter wheel 11 is arranged on the side where the operator is located, and the small-diameter wheel 12 is arranged on the side supporting the control washer 200. A minimum width corresponding to the width of the control panel 200 can be maintained, and it can be used at a narrow entrance or passage in a work site, and can be transported safely without falling.
[0042]
Further, according to the transport device of the present embodiment, the support fitting 34 is provided with the drop-off prevention protrusion 34A that is inserted into the hole 41 of the attachment 40 provided on the control panel 200 that is the object to be transported, and the support pin is provided by the safety pin 34C. 34 and the attachment 40 are fixed, so that the control panel 200 can be prevented from falling off, which contributes to safety.
[0043]
As the drop-off preventing protrusions attached to the support bracket 34, a protrusion 34D having a square cross section as shown in FIG. 5 and a protrusion 34E with a spring shown in FIG. 6 can be employed. In the case of the projection 34E with a spring shown in FIG. 6, when a portion other than the hole 41 of the jig attachment 40 is positioned, the projection 34E is pushed in, and when a part of the hole 41 is peeked on the axis of the projection 34E, the spring force Can be positioned easily.
[0044]
A small-diameter wheel 12 is attached to the conveyed object side, and a large-diameter wheel 11 is attached to the other, but a large-diameter wheel is attached to the conveyed object side, and a small-diameter wheel is attached to the other. It is also possible and can be selected as appropriate depending on the weight of the object to be conveyed, the form of the conveyance path, and the like. Moreover, it can replace with the hydraulic jack 33 and the electric jack by battery drive or external power supply drive is also employable. Furthermore, the number of dropout prevention protrusions may be one or a plurality. In addition, as the shape, material, and the like of the support bracket 34, the attachment 40, and the like, appropriate ones can be adopted according to required strength, the shape of the object to be conveyed, and the like.
