Description

[Detailed description of the invention] [Field of industrial application] This invention connects the opening/closing device of the electric opening/closing canopy provided on the gate-shaped pallet and the power supply provided on the carrier vehicle carrying the gate-shaped pallet. Regarding a power supply device.

[Conventional technology]

When transporting heavy objects in steelworks, ports, etc., it is possible to move a transport vehicle between the legs of a gate-shaped pallet, raise the platform of the transport vehicle, and carry the gate-shaped pallet. In most cases, a gate-type pallet equipped with an electrically-operated opening/closing canopy on the top surface of the receiving platform does not include a power source for opening/closing the canopy, so power for the canopy opening/closing device is supplied from the transport vehicle.

[Problem that the invention attempts to solve]

For this reason, conventionally, the driver of the transport vehicle had to get out of the vehicle and manually connect and disconnect the power supply device each time, resulting in poor work efficiency.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a power supply device that can connect and disconnect power between a gate-shaped pallet and a transport vehicle without the driver getting out of the vehicle.

[Means for solving problems]

In order to achieve the above object, the present invention has an electric opening/closing type canopy that covers the upper part of the loading platform of the gate-shaped pallet, which enters between the legs provided on both sides of the lower part of the loading platform, raises the loading platform, and lifts the gate-shaped pallet. In a power supply device that connects a power source provided in a conveyance vehicle to be carried, a contact point for receiving power of the hood opening/closing device is provided on the inside of the leg of the gate-shaped pallet, and a contact point on the gate-shaped pallet side is provided when the conveyance vehicle is carrying a pallet. A contact connected to the power supply is provided at the lower part of the loading platform at a position facing the above-mentioned power supply by means of a cylinder so as to protrude horizontally in the width direction of the vehicle body so as to be connectable to the contact on the gate-type pallet side, and the contact on the gate-type pallet side and the contact on the transport vehicle side. One of the contacts is a clip-shaped contact, and the other is a contact made of a horizontal metal plate that is longer in the horizontal direction.

[Effect]

Thereby, by operating the cylinder, the contacts on the gate-shaped pallet and the contacts on the transport vehicle can be connected and disconnected.

Five conductive metal plates 12, such as rigid trolleys, are placed horizontally in the longitudinal direction of the gate-shaped pallet 1 in the vertical direction with insulators 13 interposed between them so as not to protrude beyond the width of the legs 3 inside the pallet 3. The metal plate 12 is connected to the canopy opening/closing device 5 via a cord 14, and in this embodiment, the metal plate 12 is horizontally connected to the canopy opening/closing device 5 through a cord 14 to allow for an error in stopping the transport vehicle 7 at a fixed point.
The length is 450mm.

On the other hand, a case 15 with an opening on the side of the vehicle body is fixedly installed at the bottom of the loading platform 8 of the transport vehicle 7.
A contact 11 is provided inside. This contact point 11
In this example, five conductive metal plates 17 connected to a power source via cords 16 are provided in the vertical direction through insulators 18, and the metal plate 12 of the contact 6 is held at the tips of these metal plates 17. It is constructed by fixing a clip-shaped connection terminal 19 to the case 15.
It is provided at the tip of a support plate 20 that is movable in the width direction of the vehicle body.

Further, a cylinder 21 is provided inside the case 15, and a rod 22 of the cylinder 21 is connected to a bracket 23 provided behind the contact point 11 of the support plate 20. 20, the contact 11 protrudes from the side of the vehicle body through the opening of the case 15, the metal plate 12 of the contact 6 is held between the clip-shaped connection terminal 19, the contact 6 and the contact 11 are connected, and the rod 22 By contracting the contact point 6 and the contact point 11, the contact point 6 and the contact point 11 can be separated and the contact point 11 can be housed in the case 15.

The cylinder 21 extends the rod 22 and connects the contact 1.
A limit switch 24 is provided on the side of the cylinder 21 to confirm that the rod 22 is retracted, the contact 11 is disconnected from the contact, and the contact 11 is completely stored in the case 15. is built into the cylinder 21.

Further, a dustproof door 25 is provided at the opening of the case 15, and is opened and closed by a link mechanism 26 in conjunction with the expansion and contraction of the rod 22 of the cylinder 21.

With this configuration, the transport vehicle 7 can enter between the legs 3 and 3 of the gate-shaped pallet 1 and move onto the loading platform 8.
When the gate-shaped pallet 1 is lifted up and the gate-shaped pallet 1 is carried, the contact point 6
Since the contact point 11 is in the opposite position, the driver's seat 1
Operate the cylinder 21 from 0 to connect the contacts 6 and 11.
The hood opening/closing device 5 can be connected to operate the hood opening/closing device 5 to safely open/close the hood 4 in a short time, and the contacts 6 and 11 can be disconnected from the driver's seat 10, thereby improving work efficiency. Can be done.

In the above embodiment, the clip-shaped connection terminal 19 is provided on the contact 11 on the transport vehicle 7 side, but the same effect can be achieved even if the clip-shaped connection terminal 19 is provided on the contact 6 side of the gate-shaped pallet 1. play.

[Effect of idea]
