[0005] Patent Document 1: Japanese Patent Application Publication No. 8-245191 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] In the technology described in Patent Document 1, firstly, when supporting electric vehicles or other vehicles with partially missing wheels (such as accident vehicles) using the wheel portion, it is difficult to adjust the vehicle for horizontal support. When removing batteries from a vehicle carrying batteries as weights and transferring them to a platform, if the vehicle tilts, problems such as the battery falling and the operator's hand easily getting caught between the battery and the platform can occur. Secondly, there is a problem that after moving the movable support according to the vehicle's wheelbase and track width, installing anti-movement fasteners is time-consuming.

[0008] The present invention was made in view of the above, and its object is to provide a vehicle platform that enables easy leveling of the vehicle and facilitates the removal of heavy objects such as batteries with high safety.

[0009] Methods for solving problems

[0010] The vehicle support frame of the present invention includes: a first support portion for supporting a first wheel of a vehicle; a second support portion for supporting a second wheel of the vehicle that is located away from the first wheel along the width direction of the vehicle; a third support portion for supporting a third wheel of the vehicle that is located away from the first wheel along the length direction of the vehicle; a fourth support portion for supporting a fourth wheel of the vehicle that is located away from the third wheel along the width direction of the vehicle; a first frame having the first support portion and the second support portion at a predetermined height; and a second frame separate from the first frame and having the third support portion and the fourth support portion at a predetermined height, wherein the first frame... The first support portion or the second support portion moves in the width direction of the vehicle. In the second frame, the third support portion and the fourth support portion move in the length direction of the vehicle. The third support portion or the fourth support portion also moves in the width direction. The first support portion has a first height display portion and a first lifting adjustment portion between itself and the first frame. The second support portion has a second height display portion and a second lifting adjustment portion between itself and the first frame. The third support portion has a third height display portion and a third lifting adjustment portion between itself and the second frame. The fourth support portion has a fourth height display portion and a fourth lifting adjustment portion between itself and the second frame.

[0011] Therefore, by adjusting the position of each support to match the vehicle size, the underfloor drive battery of all vehicles can be removed. By separating the legs front and back, space for people and clamps to pass through can be created at least in the left and right directions of the vehicle, which can improve the workability of battery replacement and other operations and make it easier to level the vehicle, thus achieving a high level of safety in the removal of heavy objects such as batteries.

[0012] Furthermore, the vehicle support frame of the present invention includes: a first support portion for supporting a first wheel of a vehicle; a second support portion for supporting a second wheel of the vehicle that is located away from the first wheel along the width direction of the vehicle; a third support portion for supporting a third wheel of the vehicle that is located away from the first wheel along the length direction of the vehicle; a fourth support portion for supporting a fourth wheel of the vehicle that is located away from the third wheel along the width direction of the vehicle; a first frame having the first support portion and the second support portion at a predetermined height; and a second frame separate from the first frame and having the third support portion and the fourth support portion at a predetermined height, wherein the first frame... In the first frame, either the first or second support portion moves in the width direction of the vehicle. In the second frame, the third and fourth support portions move in the length direction of the vehicle, and the third or fourth support portion also moves in the width direction. The first frame has a first beam erected in the width direction. The first beam has a bottom and a sidewall portion. The sidewall portion is located at both ends of the bottom of the first beam in the width direction and above the bottom of the first beam. The first or second support portion has a first spring and a first roller, or a second spring and a second roller, deformable due to the weight of the vehicle, on its bottom surface. Two rollers roll on the bottom of the first beam and move inside the width direction of the sidewall of the first beam. The second frame has a second beam erected in the length direction and a first movable part that moves along the second beam. The first movable part has the third support. The second beam has a second beam bottom and a second beam sidewall. The second beam sidewall is located at both ends in the width direction of the second beam bottom and above the second beam bottom. The first movable part has a third spring and a third roller that deform due to the weight of the vehicle on its bottom surface. The third roller rolls on the bottom of the second beam and moves inside the width direction of the sidewall of the second beam. The first movable part also has a third support. The vehicle platform has a third beam and a second movable part that moves along the third beam. The second movable part has the fourth support part. The third beam has a bottom and a sidewall portion. The sidewall portion is located at both ends of the bottom of the third beam in the width direction and above the bottom of the third beam. The second movable part has a fourth spring and a fourth roller that deform due to the weight of the vehicle on its bottom surface. The fourth roller rolls on the bottom of the third beam and moves inside the sidewall portion in the width direction. When the vehicle platform is not carrying a vehicle, the height dimension of the first spring and the first roller or the height dimension of the second spring and the second roller is larger than the height dimension of the sidewall portion of the first beam.When a vehicle is mounted on the vehicle frame, the height dimension of the first spring and the first roller, or the height dimension of the second spring and the second roller, is less than or equal to the height dimension of the side wall of the first beam. When the vehicle frame is not mounted on the vehicle, the height dimension of the third spring and the third roller is greater than the height dimension of the side wall of the second beam. When the vehicle frame is mounted on the vehicle, the height dimension of the third spring and the third roller is less than or equal to the height dimension of the side wall of the second beam. When the vehicle frame is not mounted on the vehicle, the height dimension of the fourth spring and the fourth roller is greater than the height dimension of the side wall of the third beam. When the vehicle frame is mounted on the vehicle, the height dimension of the fourth spring and the fourth roller is less than or equal to the height dimension of the side wall of the third beam.

[0013] Therefore, after the movable support is moved according to the dimensions of the vehicle's wheelbase and track, the time spent installing fasteners to prevent movement can be omitted, and it can be easily fixed.

[0014] In the above invention, the first support portion, the second support portion, the third support portion and the fourth support portion are provided with wheel stops to prevent the rotation of the vehicle's wheels.

[0015] In the above invention, the first frame has a first beam erected in the width direction, and a first support or a second support that moves in the width direction clamps the first beam from above and below with rollers and moves along the first beam in the width direction. The second frame has a second beam erected in the length direction and a first movable part that moves along the second beam. The first movable part clamps the second beam from above and below with rollers and moves along the second beam in the length direction. The first movable part has a third beam erected in the width direction and a second movable part that moves along the third beam. The second movable part clamps the third beam from above and below with rollers and moves along the third beam in the width direction.

[0016] In the invention described above, among the first support portion, the second support portion, the third support portion, and the fourth support portion, the support portion that moves in the width direction has a side plate that contacts the side of the supported wheel and moves in the width direction by being pressed against by the wheel.

[0065] Figure 2 This is a side view of an electric vehicle (EV). The EV has a drive battery (BAT) located under the floor, which powers the motors that drive the wheels. In the following description, the wheelbase of the EV is defined as L, and the track width as W.

[0066] Figure 3This is a front view of the vehicle mounting platform 1 before mounting the electric vehicle (EV). The operator removing the drive battery (BAT) from the EV first moves the rear wheel support 20 in the X-axis direction so that the distance between the first support 31 and the third support 21, and the distance between the second support 32 and the fourth support 22, become the wheelbase (L) of the EV. Here, since the rear wheel support 20 can move in the X-axis direction using the rollers WR of the movable part 20R and WL of the movable part 20L, the operator can easily adjust the distance between the first support 31 and the third support 21, and the distance between the second support 32 and the fourth support 22.

[0067] Furthermore, the operator sets the interval between the first support portion 31 and the second support portion 32 to be shorter than the wheel track width, i.e., W, and also sets the interval between the third support portion 21 and the fourth support portion 22 to be shorter than the wheel track width, i.e., W. Here, since the second support portion 32 can move in the Y-axis direction using the roller WC of the movable portion 30, and the fourth support portion 22 can move in the Y-axis direction using the roller WD of the movable portion 20C, the operator can easily adjust the interval between the first support portion 31 and the second support portion 32, as well as the interval between the third support portion 21 and the fourth support portion 22.

[0068] Figure 4A and Figure 4B This diagram illustrates the operation of mounting an electric vehicle (EV) on a vehicle mounting platform 1. The operator (OP) is shown below. Figure 4A As shown, the electric vehicle (EV) is placed on the fork of the forklift FT, with the left side of the left front wheel pressing against side plate 322 and the left side of the left rear wheel pressing against side plate 222, causing the electric vehicle (EV) to move in the +Y direction. Because the left side of the left front wheel presses against side plate 322 and the left side of the left rear wheel presses against side plate 222, therefore, as... Figure 4B As shown, the movable part 30 causes the second support part 32 to move in the +Y direction, and the movable part 20C causes the fourth support part 22 to move in the +Y direction.

[0069] Figure 5A This diagram shows the state in which an electric vehicle (EV) is mounted on a vehicle mounting platform 1. (As shown in the diagram...) Figure 4B As shown, with the right front wheel on the first support 31 and the right rear wheel on the third support 21, the operator OP lowers the forks of the forklift FT, placing the right front wheel on the first support 31, the left front wheel on the second support 32, the right rear wheel on the third support 21, and the left rear wheel on the fourth support 22. Since each wheel of the electric vehicle EV mounted on the vehicle platform 1 is located between the wheel stops of each support, forward and backward movement is suppressed.

[0070] Figure 5BThis diagram shows the state in which the electric vehicle (EV) will be placed in front of the vehicle mounting platform 1. (See diagram below.) Figure 5B As shown, even if the interval between the first support portion 31 and the third support portion 21, and the interval between the second support portion 32 and the fourth support portion 22 are longer than the wheelbase L, by having the right rear wheel of the electric vehicle EV contact the wheel stop 211F and the left rear wheel contact the wheel stop 221F when the fork teeth of the forklift FT are lowered, the movable portions 20L and 20R move in the +X direction. Therefore, the interval between the first support portion 31 and the third support portion 21, and the interval between the second support portion 32 and the fourth support portion 22, can be matched with the wheelbase L of the electric vehicle EV.

[0071] Figure 5C This diagram shows the state of an electric vehicle before and after being placed on a height-adjusting platform for a vehicle in one embodiment. Figure 5B The lifting mechanism of each tire support in this embodiment. Figure 5C The example shown is an enlarged view of region S0, which is part of the support.

[0072] That is, such as Figure 5C As shown, the first support 31 has a scale 44a serving as a first height display and a lifting amount display 44b, and a hydraulic jack 45 serving as a first lifting adjustment unit, located between it and the first platform 3. Similarly, the second support 32 has a scale 44a serving as a second height display and a lifting amount display 44b, and a hydraulic jack 45 serving as a second lifting adjustment unit, located between it and the first platform 3. Furthermore, the third support 21 has a scale 44a serving as a third height display and a lifting amount display 44b, and a hydraulic jack 45 serving as a third lifting adjustment unit, located between it and the second platform 2. Similarly, the fourth support 22 has a scale 44a serving as a fourth height display and a lifting amount display 44b, and a hydraulic jack 45 serving as a fourth lifting adjustment unit, located between it and the second platform 2.

[0073] like Figure 5C As shown, a hollow, four-sided prism tire support guide 43 is disposed on the outer side of the tire support base 44. Furthermore, a hydraulic jack 45 is fixed to the tire support base 44. By raising and lowering the hydraulic jack 45, the tire support guide 43 can be raised and lowered along the tire support base 44. That is, the tire support guide 43, the tire support base 44, and the hydraulic jack 45 constitute a lifting mechanism. Using a scale 44a attached to four locations on each tire support base 44 and a lifting amount display 44b, the lifting amount of each tire support guide 43 is adjusted relative to the tilt angle of the vehicle mounted on the first to fourth racks using trigonometric ratios and trigonometric functions. This allows for high-precision adjustment of the vehicle's levelness.

[0074] In this way, even if a tire is partially missing in an accident vehicle, the vehicle can be raised and lowered using the hydraulic jack 45 built into the tire support. The vehicle's level can be precisely determined and maintained using the attached scale 44a and the lifting amount display 44b. That is, even if a tire is partially missing in an accident vehicle, by raising or lowering the hydraulic jack 45 at the tire support base 44 at the missing tire location, the tilt can be calculated based on the scale 44a attached to each tire support base 44 and the lifting amount display 44b, or by using a tilt meter (not shown) to add the height displacement corresponding to the tilt height that makes the tilt angle approximately 0 degrees. This ensures a high degree of vehicle levelness and allows for high-precision matching with the table lift and the forklift's bearing surface (horizontal plane), thus enabling the battery to be removed horizontally.

[0075] Figure 5D This diagram shows the electric vehicle mounted on a vehicle platform in front of and behind a wheel-holding platform. Figure 5D Examples of the various support components are shown. Figure 5D The example shown is to illustrate as Figure 5B An enlarged view of region S, a portion of the support shown.

[0076] That is, such as Figure 5DAs shown, the first platform 3 has beams 301F and 301R, which serve as first beams, erected in the width direction. Beams 301F and 301R have a first beam bottom and a first beam sidewall portion, which is located at both ends of the first beam bottom in the width direction and above the first beam bottom. The first support portion 31 or the second support portion 32 has a spring 48a (first spring) and a roller 49a (first roller) on its bottom surface, which deforms due to the weight of the vehicle; or a spring 48b (second spring) and a roller 49b (second roller). The roller 49a or roller 49b rolls on a travel track 46, which serves as the bottom of the first beam, and moves inside the travel track sidewall 46a, which serves as the sidewall of the first beam, in the width direction. The second platform 2 has beams 23R and 23L, which are erected in the longitudinal direction as second beams, and movable parts 20R and 20L, which are movable parts in the first movable direction and move along the beams 23R and 23L. The movable parts 20R and 20L, which are the first movable parts, have a third support 21. The beams 23R and 23L, which are the second beam bottom, have a running track sidewall 46a, which are located at both ends in the width direction of the second beam bottom and above the bottom of the second beam bottom. The movable parts 20R and 20L, which are the first movable parts, have a spring 48a, which is a third spring and a roller 49a, which are third rollers, on their bottom surfaces. The roller 49a, which is the third roller, rolls on the running track 46, which is the bottom of the second beam, and moves inside the running track sidewall 46a, which is the second beam sidewall, in the width direction. Movable parts 20R and 20L, which are first movable parts, also have beams 201F and 201R, which are third beams erected in the width direction, and movable part 20C, which is a second movable part that moves along beams 201F and 201R. Movable part 20C has a fourth support 22. The beams 201F and 201R, which are third beams, have a travel track as the bottom of the third beam and travel track sidewalls 46a, which are located at both ends in the width direction of the bottom of the third beam and above the bottom of the third beam, and serve as the sidewalls of the third beam. Movable part 20C, which is a second movable part, has a spring 48b, which is a fourth spring that deforms due to the weight of the vehicle, and a roller 49b, which is a fourth roller, on its bottom surface. The roller 49b rolls on the travel track 46, which is the bottom of the third beam, and moves inside the travel track sidewall 46a, which is the sidewall of the third beam, in the width direction.The dimensions in the height direction of spring 48a (first spring) and roller 49a (first roller) when the vehicle platform is not carrying a vehicle, or the dimensions in the height direction of spring 48b (second spring) and roller 49b (second roller) are larger than the dimensions in the height direction of the running track sidewall 46a (first beam sidewall). The dimensions in the height direction of spring 48a (first spring) and roller 49a (first roller) when the vehicle platform is carrying a vehicle, or the dimensions in the height direction of spring 48b (second spring) and roller 49b (second roller) are larger than the dimensions in the height direction of the running track sidewall 46a (first beam sidewall). The dimensions in the degree direction are less than or equal to the height dimension of the travel track sidewall 46a, which serves as the sidewall of the first beam. When the vehicle platform is not carrying a vehicle, the height dimensions of the spring 48a (the third spring) and the roller 49a (the third roller) are larger than the height dimension of the travel track sidewall 46a, which serves as the sidewall of the second beam. When the vehicle platform carries a vehicle, the height dimensions of the spring 48a (the third spring) and the roller 49a (the third roller) are less than or equal to the height dimension of the travel track sidewall 46a, which serves as the sidewall of the second beam. When the vehicle platform is not carrying a vehicle, the height dimensions of the spring 48b (the fourth spring) and the roller 49b (the fourth roller) are larger than the height dimension of the travel track sidewall 46a, which serves as the sidewall of the third beam. When the vehicle platform carries a vehicle, the height dimensions of the spring 48b (the fourth spring) and the roller 49b (the fourth roller) are less than or equal to the height dimension of the travel track sidewall 46a, which serves as the sidewall of the third beam.

[0077] Therefore, the tire support 47, which can be adjusted arbitrarily in the front-rear and left-right directions to match the size of the vehicle, has a driving function. Due to the weight of the vehicle after it is placed, the springs 48a and 48b at the lower part of the tire support 47 sink. As a result, the lower part of the tire support 47 strongly interferes with the upper part of the travel track 46. Therefore, the frictional resistance between the lower part of the tire support 47 and the upper part of the travel track 46 can suppress the front-rear movement and the left-right movement and maintain the position.

[0078] Specifically, such as Figure 5D As shown, the tire support 47, springs 48a and 48b, and rollers 49a and 49b are integrally formed. Before the vehicle is placed and mounted ( Figure 5D (See the left figure). Through the action of springs 48a and 48b, the lower part of the tire support 47 is in a non-contact state with the upper part of the travel track 46. In this state, the tire support 47 can move freely in the front-rear and left-right directions, thus allowing it to match the size of the vehicle.

[0079] Next, when the vehicle is mounted, the tire support 47, which has been raised by springs 48a and 48b, sinks and is fixed by friction through strong interference with the upper part of the travel track sidewall 46a of the travel track 46, thus maintaining the position of the tire support 47. At the same time, it is possible to avoid applying the full weight of the vehicle to the rollers 49a and 49b. Therefore, a portion of the vehicle's weight is distributed across the travel track 46, the travel track sidewall 46a, and the tire support 47, thereby improving the durability of the rollers 49a and 49b.

[0080] With this configuration, the springs 48a and 48b located at the rollers 49a and 49b of each traveling trolley prevent contact with the front and rear beams and left and right beams when moving in their respective forward and backward and left and right directions, allowing the traveling trolleys to move smoothly in these directions. Furthermore, after the vehicle is mounted, the weight of the vehicle causes each tire support and each trolley with a traveling function to sink via the springs 48a and 48b on each traveling track 46. This causes strong interference between each traveling trolley and the front and rear beams and left and right beams, distributing the vehicle's weight and reducing the load on the traveling wheels of the traveling trolleys, thus improving durability. Additionally, the need to install four fixing parts to prevent trolley movement is eliminated, thus improving work efficiency.

[0081] In conventional technologies, when placing a vehicle onto a platform with part of its wheel missing, such as in a wrecked vehicle, it is difficult to maintain the vehicle horizontally. Therefore, when removing the battery using a lift or forklift, the vehicle's tilt does not result in a level position, and the battery is removed while unstable. This could lead to the operator's hand being caught in the falling battery, or the battery falling to the ground and potentially trapping the operator or damaging the battery. Furthermore, the entire weight of the vehicle is concentrated on one fixed part of the tire support and the three supporting parts of the running wheels. This reduces the durability of the three supporting parts of the running tires, making smooth forward, backward, left, and right movement difficult. Even when four anti-movement fixings are installed in the running tire support, the efficiency of fixing varies depending on the vehicle's size.

[0082] In contrast, in this embodiment, by installing a lifting mechanism on the tire support, the vehicle can be kept level even when at least one, two, or three of the four wheels of a vehicle such as an accident vehicle are missing. When disassembling components such as large drive batteries mounted under the floor, disassembly can be carried out stably while maintaining a level position by matching the support clamp's worktable lift and flat tray. Furthermore, for the tire support, which can move arbitrarily along the wheelbase and track directions, the manual fixing mechanism, which is matched to the vehicle's size, can be replaced by automatic fixing at any position using the vehicle's own weight.

[0083] Figure 6 This diagram illustrates the operation of removing the drive battery (BAT) from an electric vehicle (EV). The operator (OP) lowers a platform lift (TL) for holding the drive battery (BAT) between platform 1 (3) and platform 2 (2) under the EV. The OP then places the drive battery (BAT) removed from under the EV's floor onto the platform lift (TL) and moves it out between platform 1 (3) and platform 2 (2).

[0084] Here, the electric vehicle (EV) is supported not by the rocker panel, but by the wheels. Therefore, the drive battery (BAT) removed from under the floor will not interfere with the part supporting the EV, allowing for easy removal of the drive battery BAT. Furthermore, the vehicle mounting platform 1 can adjust the X-axis position of the rear wheel support 20 to match the wheelbase (L), and adjust the spacing between the third support 21 and the fourth support 22, as well as the spacing between the first support 31 and the second support 32, to match the track width (W). Therefore, the drive battery BAT can be removed from various vehicle models, from small cars to large cars. Additionally, the vehicle mounting platform 1 can independently adjust the spacing between the third support 21 and the fourth support 22, as well as the spacing between the first support 31 and the second support 32. Therefore, even EVs with different track widths at the front and rear wheels can be supported. Furthermore, in the vehicle support platform 1, the first platform 3, which supports the front wheels, and the second platform 2, which supports the rear wheels, are separate. Therefore, when the operator (OP) and the work platform lift (TL) move downwards towards the electric vehicle (EV), there are no obstructions in their movement paths, allowing for efficient operation. Additionally, in this embodiment, each movable part is configured to clamp a beam, thus preventing it from detaching from the beam. Moreover, when the vehicle mounted on the vehicle support platform 1 is a hybrid vehicle or a plug-in hybrid vehicle, various vehicle models can be mounted, and components can be removed from under the floor. Furthermore, when the vehicle mounted on the vehicle support platform 1 is a motor vehicle, various vehicle models can be mounted, and work can be performed under the floor.

[0085] [Variation Example]

[0086] The embodiments of the present invention have been described above, but the present invention is not limited to the embodiments described above and can be implemented in various other ways. For example, the present invention can be implemented by modifying the embodiments described above as follows. Furthermore, the embodiments described above and the following modifications can also be combined. Embodiments constructed by appropriately combining the constituent elements of the various embodiments and modifications described above are also included in the present invention. In addition, those skilled in the art can easily derive further effects and modifications. Therefore, the broader scope of the present invention is not limited to the embodiments and modifications described above, and various changes can be made.

[0087] Figure 7 This is a front view of a vehicle support platform according to a modified embodiment of the present invention. In the present invention, the position of the support leg 212F can also be set from... Figure 1B The position shown is offset to the -X direction, and the position of the support leg 312R is set from the position shown. Figure 1B The position shown is offset in the +X direction. In this modified example, even if the wheelbase, L, is the same, the distance from support leg 212F to support leg 312R becomes longer, thus ensuring a large space under the electric vehicle EV.

[0088] In this invention, the fourth support portion 22 may also be configured without side plates 222, and the second support portion 32 may also be configured without side plates 322. In this configuration, when the electric vehicle EV is mounted on the vehicle frame 1, the spacing between the first support portion 31 and the second support portion 32 is adjusted in advance to match the wheelbase width W of the electric vehicle, and the spacing between the third support portion 21 and the fourth support portion 22 is also adjusted.

[0089] Figure 8A as well as Figure 8BThis is a schematic diagram of the third support portion 21A of a modified embodiment of the present invention. The beam 23Ra is an H-beam, a member that replaces the beam 23R and is erected along the X-axis from the support column 25R to the support column 26R. A fixing plate 217, which is a strip-shaped sheet metal, is fixed along the X-axis at the end of the beam 23Ra in the -Y direction. Multiple through holes 217a extending in the Y-axis direction are formed in the fixing plate 217 along the X-axis direction. The support leg 212 is a member that supports the base plate 210 and is fixed to the base 215. The base 215 is a rectangular plate-shaped member, with plate-shaped and trapezoidal side plates 213 fixed at its ends in the +Y and -Y directions. A roller support portion 216 that supports the roller WRa is fixed below the base 215. A rectangular and plate-shaped side plate 214 is fixed to the side plate 213. The side plate 214 supports the roller WRb. The third support 21A can clamp the beam 23Ra from the +Z and -Y directions using rollers WRa and WRb, and move in the X-axis direction. With this configuration, the beam 23Ra is clamped vertically by rollers WRa and WRb, and the beam 23Ra is clamped in the Y-axis direction by the side plate 214, thus preventing the third support 21A from detaching from the beam 23Ra. Furthermore, a through hole 214a is formed in the side plate 214, extending in the Y-axis direction. The rod-shaped portion of the pin 218, which is in the shape of a lifting eye bolt, is inserted into the through hole 214a and the through hole 217a from the -Y direction. After the operator places the right rear wheel of the electric vehicle EV on the third support 21A, they insert the pin 218 from the -Y direction side into both the through hole 214a and the through hole 217a. When pin 218 is inserted into both through holes 214a and 217a, even if a force in the X-axis direction is applied to the third support portion 21A, pin 218 will still be engaged with the fixing plate 217. Therefore, it is possible to prevent the rear wheel support portion 20, the fourth support portion 22, and the third support portion 21A from moving in the X-axis direction. Furthermore, the other fourth support portion 22 and second support portion 32 can also be configured in the same way as the third support portion 21A, with corresponding fixing plates 217 provided on the beam, and pin 218 used to prevent movement in the Y-axis direction.

[0090] In this invention, the configuration may also be as follows: the fourth support portion 22 is fixed to the movable portion 20L, the third support portion 21 is movable in the Y-axis direction, the second support portion 32 is fixed to the beam 33L, and the first support portion 31 is movable in the Y-axis direction. In this modified example, the electric vehicle EV is transported by a forklift FT from the +Y-axis direction to the -Y-axis direction and placed on the vehicle platform 1.

[0091] Alternatively, the front wheels can be placed on the second support platform 2, and the rear wheels can be placed on the first support platform 3. In this case, the fourth support part 22 supports the right front wheel of the electric vehicle EV, the third support part 21 supports the left front wheel of the electric vehicle EV, the second support part 32 supports the right rear wheel of the electric vehicle EV, and the first support part 31 supports the left rear wheel of the electric vehicle EV.
