Description

Technical Field

[0001] The present invention relates to a gantry and pallet for transporting a switchgear panel (SWG) on a truck, specifically a gantry for transporting a switchgear panel.

Background Art

[0002] Conventionally, when transporting multiple switchgear panels on a truck, as shown in Fig. 4(a), the switchgear panels S are placed in parallel side by side (without being placed on a gantry) in the width direction of the loading platform T1 of the truck T, and the two switchgear panels S are fixed to the truck T with ropes L. After transporting to the site, as shown in Fig. 4(b), the ropes are removed on site, and the switchgear panels S are unloaded from the truck T one by one using a crane C or a forklift.

[0003] However, since only two switchgear panels S are directly placed on the loading platform T1 of the truck T, when one switchgear panel S is unloaded from the truck T using a crane C or a forklift, the other switchgear panel S may become unstable and sway. For this reason, there is a risk that the switchgear panels S may come into contact with each other or the other switchgear panel S may topple over. Therefore, it is necessary for the operator M to use a catwalk K or the like to guide one switchgear panel S and pay careful attention.

[0004] Furthermore, even when one switchgear panel S has been unloaded from the truck T, as shown in Fig. 4(c), since one switchgear panel S remains directly placed on one side in the width direction of the loading platform T1 of the truck T, there is a risk that the switchgear panel S is unstable and may topple over. Therefore, it is necessary for the operator M to pay attention and hold down the switchgear panel S on the truck T if necessary.

[0005] On the other hand, there is known a loading platform that enables easy loading and unloading of members and can prevent the members from collapsing during transportation (see, for example, Patent Document 1). This loading platform includes a base placed on the truck bed, a substantially triangular prism-shaped support frame erected over the entire width in the longitudinal center portion of the base, and floorboards placed on the base on both sides of the support frame.

Summary of the Invention

Problems to be Solved by the Invention

[0007] By the way, the loading platform described in Patent Document 1 may be suitable for loading plate-shaped members, but the switchgear panel is in the shape of a box-shaped cabinet and is a heavy object, so it cannot be stably placed on the truck bed using the loading platform described in Patent Document 1.

[0008] Therefore, an object of the present invention is to provide a mounting platform for transporting a switchgear panel that enables two switchgear panels to be stably placed in the width direction of the truck bed.

Means for Solving the Problems

[0009] To solve the above problems, the invention according to claim 1 includes a base plate extending and placed in the width direction of the truck bed, and two fixed on the base plate, on which switchgear panels are respectively placed It includes one pedestal body, and with the base plate placed on the cargo bed of the truck, the two pedestal bodies are fixed on the base plate such that the two pedestal bodies are arranged in parallel in the width direction of the cargo bed of the truck. Bolt holes are formed in the two pedestal bodies at the same positions as the bolt insertion holes formed at the lower part of the switch gear panel. It is a pedestal for transporting a switch gear panel, characterized by the above.

[0010] The invention according to claim 2 is characterized in that, in the pedestal for transporting a switch gear panel according to claim 1, the planar shape of the pedestal body is formed to be substantially the same as the outer shape of the lower surface of the switch gear panel.

[0011] The invention according to claim 3 is characterized in that, in the pedestal for transporting a switch gear panel according to claim 1 or 2, the length of the base plate in the width direction of the cargo bed is set to be substantially the same as the width dimension of the cargo bed.

[0012] The invention according to claim 4 is characterized in that, in the pedestal for transporting a switch gear panel according to claim 1 or 2, the length of the base plate in the width direction of the cargo bed is adjustable.

Advantages of the Invention

[0013] According to the invention described in claim 1, by placing the base plate on the cargo bed of the truck, placing the switch gear panel on each of the two pedestal bodies, and fastening the bolts through the bolt insertion holes of the switch gear panel and the bolt holes of the pedestal body, the switch gear panels are placed in a state of being arranged in parallel in the width direction of the cargo bed of the truck. In this way, since two switch gear panels are placed and fixed in parallel via the pedestal bodies on the base plate extending in the width direction of the cargo bed of the truck, it is possible to maintain a stable placement state of the two switch gear panels during transportation.

[0014] Also, even when one switchgear panel is lifted by a crane or the like and removed from the truck, the other switchgear panel remains placed and fixed on the base plate extending in the width direction of the truck bed, so it is possible to maintain a stable state. Moreover, since bolt holes are formed at the same positions as the bolt insertion holes of the switchgear panel and it is only necessary to fasten the bolts through the bolt insertion holes and the bolt holes, no additional processing or design changes are required for the switchgear panel.

[0015] According to the invention described in claim 2, since the planar shape of the gantry body is formed to be substantially the same as the outer shape of the lower surface of the switchgear panel, substantially the entire bottom of the switchgear panel is supported by the gantry body. Therefore, it is possible to place the switchgear panel more stably.

[0016] According to the invention described in claim 3, since the length of the base plate in the width direction of the truck bed is set to be substantially the same as the width dimension of the truck bed, the base plate is sandwiched by the side flanges of the truck, and the base plate is prevented from shifting on the truck bed. Therefore, it is possible to place and transport the switchgear panel more stably.

[0017] According to the invention described in claim 4, since the length of the base plate in the width direction of the truck bed is adjustable, by adjusting the length of the base plate according to the width dimension of the truck bed, the same effect as that of claim 3 can be obtained. As a result, it is possible to apply this gantry for transporting the switchgear panel to a plurality of types of trucks having different width dimensions of the truck bed.

Embodiments for Carrying out the Invention

[0019] Hereinafter, this invention will be described based on the illustrated embodiments.

[0020] (Embodiment 1) FIG. 1 is a perspective view showing a mount 1 for transporting a switchgear panel according to this embodiment. This mount 1 for transporting a switchgear panel is a mount - pallet for transporting a switchgear panel S by a truck T, and mainly includes one base plate 2 and two mount bodies 3. Here, it is assumed that the switchgear panel S has a substantially rectangular - parallelepiped and box - type shape in which a circuit breaker, a transformer, etc. are housed in a cabinet, and the front and back are wide and the depth is narrow.

[0021] The base plate 2 is a metal plate that is placed extending in the width direction of the loading platform T1 of the truck T. That is, it is a metal plate having a substantially rectangular planar shape, and is formed so as to extend over substantially the entire length in the width direction of the loading platform T1 when placed on the loading platform T1 of the truck T. Specifically, as shown in FIG. 2(a), with respect to the width dimension D1 of the loading platform T1 in a state where the side fender T2 of the truck T is raised, the length of the base plate 2 in the width direction of the loading platform T1 (the length in the width direction of the base plate 2) D2 is set to be substantially the same dimension (slightly shorter than the width dimension D1). Thereby, the gap with the side fender T2 becomes small, and the base plate 2 does not shift (move) in the width direction of the loading platform T1.

[0022] Also, the length D2 of the base plate 2 in the width direction of the loading platform T1 is longer than the width required to place two switch gear boards S as described later (the depth for two units), and the length of the base plate 2 in the depth direction of the loading platform T1 is set to be longer than the length (front width) of the switch gear board S. That is, in a state where two switch gear boards S are placed on the base plate 2, a margin part (surplus part) is formed around the switch gear board S.

[0023] Furthermore, the thickness and weight of the base plate 2 are set so that even when only one switch gear board S is placed on the base plate 2 as described later (Figs. 2(b) and (c)), the switch gear board S is stabilized (does not shake) by the weight of the base plate 2. Also, at the four corners of the base plate 2, ring-shaped hooks 21 are attached for suspending the base plate 2, that is, the switch gear board transport stand 1, or fixing it to the truck T with wires.

[0024] The two pedestal bodies 3 are made of metal and fixed on the base plate 2, and are each a pedestal on which the switch gear board S is placed. Their planar shape is formed to be substantially the same as the outer shape of the lower surface of the switch gear board S. That is, the outer shape (outline) of the lower surface of the switch gear board S in this embodiment is substantially rectangular and has a substantially rectangular frame-shaped bottom.

[0025] And this pedestal body 3 has substantially the same shape and configuration as the pedestal / stand when the switch gear board S is installed at the installation site. Specifically, it is composed of a channel (section steel) with a U-shaped cross-section, arranged substantially rectangularly with the opening of the channel facing inward, and its planar shape is formed to be substantially the same as the frame-shaped bottom of the switch gear board S. As a result, substantially the entire bottom of the switch gear board S is supported by the pedestal body 3.

[0026] ​These two pedestal bodies 3 are fixed on the base plate 2 such that, with the base plate 2 placed on the loading platform T1 of the truck T, they are arranged in parallel in the width direction of the loading platform T1 of the truck T. That is, they are fixed on the base plate 2 such that the long sides of the two pedestal bodies 3 are adjacent to each other and the short sides of the two pedestal bodies 3 extend linearly in the width direction of the loading platform T1. Thereby, when the switch gear panel S is placed on each pedestal body 3, the wide surfaces (front or back) of the two switch gear panels S face and are adjacent to each other, and the side surfaces (narrow surfaces) of the two switch gear panels S are placed and arranged so as to extend in the width direction of the loading platform T1.

[0027] Here, a gap between the two pedestal bodies 3 is set so that the two switch gear panels S are placed and arranged in this manner. Also, in this embodiment, the pedestal body 3 is fixed to the base plate 2 by welding, but it may be fixed by bolt fastening so that the pedestal body 3 can be attached to and detached from the base plate 2.

[0028] Further, bolt holes 31 are formed in each pedestal body 3 at the same positions as the bolt insertion holes formed at the lower part of the switch gear panel S. That is, a plurality of bolt insertion holes (dummy holes) for installing the switch gear panel S are formed at the frame-shaped bottom of the switch gear panel S, and a plurality of bolt holes 31 having the same diameter (width) as these bolt insertion holes are formed so as to overlap the bolt insertion holes. In this embodiment, these bolt holes 31 are formed in the upper surface portions of both short sides of the pedestal body 3 and are elongated holes along the short sides of the pedestal body 3. Then, when the switch gear panel S is placed on the pedestal body 3, bolts (reference numeral 4 in FIG. 2) are inserted into the bolt insertion holes of the switch gear panel S and the bolt holes 31 of the pedestal body 3, and nuts are tightened on the bolts, so that the switch gear panel S is temporarily fixed to the pedestal body 3.

[0029] Next, a method of transporting the switch gear panel S using the pedestal for transporting the switch gear panel 1 having such a configuration will be described.

[0030] To load the switch gear panel S onto the loading platform T1 of the truck T, first, as shown in Fig. 2(a), place the mounting frame 1 for transporting the switch gear panel on the loading platform T1 such that the width direction of the base plate 2 extends in the width direction of the loading platform T1. At this time, a wire may be hung on the hook 21 of the base plate 2 and tightened on the truck T to fix the base plate 2, that is, the mounting frame 1 for transporting the switch gear panel, to the truck T. Next, place the switch gear panel S on each frame body 3 and temporarily fix it by bolt fastening as described above. Subsequently, raise the side stabilizers T2 and the rear stabilizers T3 of the truck T and fix the two switch gear panels S to the truck T with ropes L.

[0031] In this state, transport the switch gear panel S to the installation site, and as shown in Fig. 2(b), remove the ropes and lower each switch gear panel S from the truck T one by one using a crane C or a forklift. At this time, first, remove only the bolts 4 between one switch gear panel S and the frame body 3, and lower one switch gear panel S from the truck T as shown in Fig. 2(c). Subsequently, remove the bolts 4 between the other switch gear panel S and the frame body 3 and lower the other switch gear panel S from the truck T.

[0032] As described above, according to this mounting frame 1 for transporting the switch gear panel, the base plate 2 is placed on the loading platform T1 of the truck T, the switch gear panel S is placed on each of the two frame bodies 3, and bolt fastening is performed through the bolt insertion holes of the switch gear panel S and the bolt holes 31 of the frame body 3, so that the switch gear panels S are placed and fixed in parallel in the width direction of the loading platform T1. In this way, since the two switch gear panels S are placed and fixed in parallel on the base plate 2 extending in the width direction of the loading platform T1 of the truck T via the frame body 3, the two switch gear panels S during transportation can maintain a stable placement state.

[0033] Also, even when one switch gear board S is lifted by a crane C or the like and lowered from the truck T, the other switch gear board S remains placed and fixed on the base plate 2 extending in the width direction of the loading platform T1 of the truck T, so it is possible to maintain a stable state. Moreover, bolt holes 31 are formed at the same positions as the bolt insertion holes of the switch gear board S, and it is only necessary to bolt and fasten through the bolt insertion holes and the bolt holes 31, so no additional processing or design changes are required for the switch gear board S.

[0034] In addition, since the planar shape of the pedestal body 3 is formed to be substantially the same as the outer shape of the lower surface of the switch gear board S, substantially the entire bottom of the switch gear board S is supported by the pedestal body 3. Therefore, it is possible to place the switch gear board S more stably.

[0035] Furthermore, since the length D2 of the base plate 2 in the width direction of the loading platform T1 is set to be substantially the same as the width dimension D1 of the loading platform T1, the base plate 2 is sandwiched by the side blades T2 of the truck T, and the base plate 2 is prevented from shifting on the loading platform T1. Therefore, it is possible to place and transport the switch gear board S more stably.

[0036] (Embodiment 2) FIG. 3 is a diagram showing the telescopic mechanism of the carrier 1 for transporting the switch gear board according to this embodiment. In this embodiment, the configuration is different from that of Embodiment 1 in that the length of the base plate 2 in the width direction of the loading platform T1 of the truck T is adjustable. For the components having the same configuration as those in Embodiment 1, the same reference numerals are given, and the description thereof is omitted.

[0037] In this embodiment, as shown in FIGS. 3(a) and 3(b), telescopic plates 22 are provided on both sides (both ends in the width direction) of the base plate body 20 to form the base plate 2. That is, the base plate body 20 has substantially the same configuration and shape as the base plate 2 in Embodiment 1, is a metal plate with a substantially rectangular planar shape, and is formed to extend in the width direction of the loading platform T1 of the truck T when placed on the loading platform T1. However, on the lower surface side of both sides, fitting portions 20a, which are spaces (steps), are formed along the side edges. Further, a plurality of long holes 20b extending in the width direction of the base plate body 20 are formed along the side edges, penetrating through the portions (thin plate portions) where the fitting portions 20a are formed.

[0038] On the other hand, the telescopic plate 22 is a strip-shaped metal plate extending along both sides of the base plate body 20, and a fitting portion 22a with a thin thickness and a contact portion 22b with a thick thickness extend over the entire length. Further, a plurality of weld bolts 23 are arranged on the upper surface side of the fitting portion 22a so as to face the long holes 20b.

[0039] In this way, the fitting portion 22a of the telescopic plate 22 is fitted into the fitting portion 20a of the base plate body 20, the weld bolt 23 is inserted into the long hole 20b, and the nut 24 is tightened on the weld bolt 23, thereby connecting the base plate body 20 and the telescopic plate 22. In this connected state, the fitting portion 20a and the telescopic plate 22 are formed so that the thickness of the base plate 2 is substantially uniform over the entire surface.

[0040] Then, by sliding the telescopic plate 22 in the width direction with respect to the base plate body 20 and tightening the nut 24 on the weld bolt 23, the length of the base plate 2 in the width direction of the loading platform T1 can be adjusted. For example, as shown in FIGS. 3(a) and 3(b), when the telescopic plate 22 is contracted toward the base plate body 20, the width of the base plate 2 becomes narrower, and as shown in FIGS. 3(c) and 3(d), when the telescopic plate 22 is extended away from the base plate body 20, the width of the base plate 2 becomes wider.

[0041] As described above, according to this embodiment, since the length of the base plate 2 in the width direction of the loading platform T1 of the truck T is adjustable, by adjusting the length of the base plate 2 according to the width dimension D1 of the loading platform T1, it is possible to prevent the base plate 2 from shifting on the loading platform T1, similar to Embodiment 1. As a result, it becomes possible to apply this switchgear panel transport stand 1 to a plurality of types of trucks T with different width dimensions D1 of the loading platform T1.

[0042] As described above, the embodiments of the present invention have been described in detail. However, the specific configuration is not limited to this embodiment, and even if there are design changes and the like within the scope not departing from the gist of the present invention, they are included in the present invention. For example, in the above embodiment, the case where the bolt holes 31 of the stand body 3 are long holes has been described, but they may be screw holes into which bolts are screwed. Also, the case where only one stand body 3 is provided in the depth direction of the loading platform T1 of the truck T has been described, but the base plate 2 may be lengthened in the depth direction of the loading platform T1, and a plurality of stand bodies 3 may be provided in the depth direction.
