2. Description of the Related Art Hot-rolled or cold-rolled steel, strip-shaped sheet metal such as aluminum and copper are used as materials for automobiles, mechanical structures or electrical equipment after being pressed, welded or punched. Has been done. This strip-shaped thin sheet metal is spirally wound by a winder at a rolling mill such as an iron mill and transported to users as a strip coil (hereinafter abbreviated as coil). These coils have various dimensions, but for example, in the case of a steel coil, one coil often reaches several tens of tons, and in order to transport at low cost, a plurality of coils are used by a large-sized and heavy-load carrier. Are being transported. As shown in FIGS. 11 and 12, the coil C is placed and stored in a predetermined number on a large number of pallets 43 having a plurality of W-shaped laterally continuous legs 44 before being transported. When carrying the coil C, as shown in FIG. 13 and FIG. 14, a special carrier 42 having an elevating body frame 45 is advanced below both legs 44 of the pallet 43, and the carrier 42 is palletized. The coil C is placed together with the coil 43, but the coil C is placed on each pallet 43 so as not to be rusted or contaminated by dust due to rainfall during transportation.
A protective cover is attached to cover the.

As a method of attaching the protective cover to the pallet 43, for example, a pair of U-shaped protective covers 46a and 46b each having a length substantially half the length of the pallet 43 shown in FIG.
Back and forth on the platform 47 of the pallet 43 (left and right in FIG. 15)
16, a pair of telescopic (bellows) protective covers 46c and 46d shown in FIG. 16 that are telescopically moved forward and backward (left and right in FIG. 16) on the loading platform 47 of the pallet 43, and a pair shown in FIG. In some cases, the retractable (bellows) protective covers 46e and 46f are rotated leftward and rightward in the transverse direction on the loading platform 47 of the pallet 43 as indicated by the alternate long and short dash line.
The protective covers 46a to 46f shown in FIGS.
Since it has to be attached to each pallet, it has a drawback of high cost. In addition, when the pallet 43 is placed on the carrier 42, the protective cover 46a
It was necessary to operate to connect a power supply for driving ~ 46f and an operation circuit. As a protective cover that solves this drawback, a protective cover device for a lift truck has been filed as an invention by the same applicants as the present applicant, and is disclosed in Japanese Patent Laid-Open No. 62-275854.
It is published as a publication. The protective cover device according to the invention described above comprises a long protective cover 60 made of a rigid material and oriented in the front-rear direction, which is attached to the vehicle body frame 52 of the transport vehicle 51. An overview will be given.

Reference numeral 51 in the drawing is a transport vehicle, and a vehicle body frame 52 that can move up and down is provided above the wheels 51a. As shown in FIG. 18, at positions on both sides of the front and rear ends of the vehicle body frame 52, cylinder mechanisms 53, 53 oriented in the width direction of the vehicle body frame 52 and cylinder mechanisms 54, 54 oriented in the vertical direction are provided. A support mechanism 55 that is movable in the width direction and the vertical direction is provided, and support portions 56 that extend upward are provided at a total of four end portions, that is, front and rear and left and right ends. The cylinder mechanisms 53, 53 are housed in the inner cylinder 59, and the cylinder mechanism 54 is housed in the inner cylinder 66. At the upper part of the support portion 56, a skeleton member made of shaped steel assembled in a lattice shape (not shown) is stretched with a stainless steel plate or the like, and is U-shaped when viewed from the front, and as shown in FIG. A door 57 is provided whose upper part is pivotally supported and whose lower part swings as an open end.
Support pins (not shown) of the supported portion 62 provided near the four corners of the support frame 61 of the protective cover 60 are fitted and supported. The pallet 70 is formed of shaped steel, and chamfers 71 are provided on the upper surfaces of the front and rear ends thereof. On the other hand, the protective cover 6
The chamfered 71
A chamfer 63 corresponding to is provided. The procedure for placing the pallet 70 on which the coil C is placed on the lift truck 51 having the protective cover 60 is as follows.

First, as shown in FIG. 20, the carrier 51 is moved forward in the direction of arrow E so as to approach the pallet 70. Next, the inner cylinder 59, which is concentric with the outer cylinder 58 provided in the lower portion of the vehicle body frame 52 in the widthwise direction at the front and rear ends shown in FIG. Move towards. Further, an inner cylinder 66 which is fixed to the widthwise outer end of the inner cylinder 59 and is concentric with the vertically oriented outer cylinder 65 and which is vertically movable by the cylinder mechanism 54 is moved upward, as shown in FIG. As described above, the support portion 56 is also moved upward, and the gap 52a is formed between the vehicle body frame 52 and the support frame 61 in the vertical direction. In this state, further carrier 5
When 1 is moved to the pallet 70 side, the upper end of one end of the pallet 70 indicated by the chain double-dashed line contacts the lower end of one end of the support frame 61 of the protective cover 60 as shown in FIG. Using the inclinations of 63 and 63, they are inserted into the space in the above-mentioned vertical gap and between the widthwise directions of the support portions 56. Next, inside the support mechanism 55 at the four corners,
As shown in FIG. 19, the third cylinder mechanism 67, which is horizontally arranged and oriented in the front-rear direction, is extended to operate the four stoppers 68.
Rotate upward to stand upright. Also, the carrier 5
1 is entered, the leg portion 72 of the pallet 70 shown in FIG.
Since the support mechanism 55 collides with the above, the cylinder mechanisms 53 and 54 shown in FIG. 18 are both reduced to move the outer cylinder 65 and the inner cylinder 66 so as to be inside the pallet 70.

When the carrier 51 is further advanced, the pallet 70
The stopper 68 shown in FIG.
The body frame 52 is arranged at a predetermined position under the pallet 70, and the protective cover 60 covers the coil C on the pallet 70. Therefore, the two doors 57 at the front and rear ends of the protective cover 60 are closed. Next, the entire body frame 52 is raised and the vertically moving cylinder mechanism 54 is contracted to slightly raise the pallet 70 while the protective cover 60 is in contact with the upper surface of the pallet 70, and the lower ends of the legs 72 are grounded. To emerge from. In this state, as shown in FIG. 21, the coil C
Are covered with a protective cover 60 and a door 57 and transported. Compared with the above-mentioned protective cover device that has protective covers on all pallets including temporary pallets, this protective cover device for lift-type transport vehicles prepares as many protective covers as the number of transport vehicles actually transported. As a result, it is possible to reduce unnecessary costs by reducing the number of protective covers. However, on the other hand, complicated operations such as extension or contraction of three types of cylinder mechanisms, driving of the vehicle body frame, and movement of the transport vehicle are required, which requires a long time for operation and alignment (alignment). ) Has the drawback of being difficult. As a carrier having a protective cover different in structure from the above, Japanese Utility Model Publication No. 3-30183 and Japanese Utility Model Publication No. 2-3132.
There are various types described in Japanese Patent No. 3 or Japanese Utility Model Publication No. 61-21305.

In the body detachable freight vehicle described in Japanese Utility Model Publication No. 61-21305, a body whose whole body is covered with a protective cover that can be opened and closed is detachably attached to the body of the carrier. Although it is a feature, it requires a large number of bodies to temporarily put a large number of coils in a warehouse as described above, and it is very difficult to stack heavy coils on a body covered with a protective cover. It is something. Japanese Utility Model Publication No. 2-33123 relates to a power supply device for supplying power from a power source of a carrier (transport vehicle) to a pallet hood opening / closing device provided with a bellows type hood (protective cover). , A clip-like contact is used for one of the contacts connected to the contact of the gate-type pallet, which is moved by a cylinder provided in the lower part of the loading tray of the carrier to face the power supply and the top opening / closing device. However, since each pallet is provided with a hood, a hood opening / closing device, and the like, there is a drawback that the cost is high because a large number of hoods are required.

[0008]

As a protective cover for preventing rusting or contamination due to rainwater or dust when the coil is transported, it is easier to mount the coil on a transport vehicle as compared with the above-mentioned prior art. Therefore, it was an object of the present invention to develop a protective cover device which has a simple structure and can be manufactured at low cost.

In the separate type protective cover device of the present invention, the combination of the above-mentioned substrate and hood support is the same as that of the conventional pallet with a protective cover. It is possible to arrange the hood assembly of the carrier by the same procedure as that of mounting on the carrier of the vehicle and without requiring complicated operations. That is, the carrier is made to enter the inside of the gate shape formed by the substrate and the hood support,
When the vehicle is stopped with the front end of the loading platform and the end of the substrate aligned, and the loading platform is slightly raised, the hood assembly is released from the engagement by the support platform and placed on the loading platform. In this state, the vehicle moves backward toward the pallet on which the coils are placed, enters the inside of the U-shape, and reaches the predetermined position where the front end of the pallet comes into contact with or comes close to the rear end of the board, and then the carrier truck. To stop and lift the loading platform. In this state, the upper plate of the pallet and the base plate of the hood assembly are substantially continuous with each other, and the protective cover rails fixed to the upper surfaces of the pallet assemblies on both sides in the transverse direction can be brought into close contact with each other. When the drive device of the hood assembly is remotely controlled by the transmitter, the protective cover can move to the pallet side on the rail and cover the entire pallet by the electric power supplied from the solar panel. An electric shutter or door is provided at the end of the protective cover on the moving side.After the predetermined installation of the protective cover is completed, the electric shutter or door is closed to cover the rear end of the pallet. The whole is protected. As described above, the separation-type protective cover device of the present invention eliminates the need to connect a power supply circuit and an operation circuit, eliminates cylinder operation, and attaches and aligns (aligns) the pallet and the protective cover device, as compared with the prior art. Further, it is possible to greatly reduce the cost because only one separate type protective cover device having a simple structure is required for each transport vehicle.
