Description

Technical Field

[0001] This disclosure relates to the technical field of transfer equipment, and more particularly to a transfer equipment for an electric stack. Background Technology

[0002] During the transfer and assembly of fuel cell stacks, the stacks need to be placed in a housing and then lifted and moved onto an electric vehicle. Since the stacks are made up of hundreds of battery cells tightly compressed together by steel belts, disc springs, end plates and other parts, the stacks are relatively large in size and weight. Moving them onto the electric vehicle using traditional chain hoisting is time-consuming and labor-intensive.

[0003] Moving the fuel cell stack using traditional hoisting methods may cause it to tilt due to uneven placement of multiple lifting rings on the hoisting chain. This not only requires multiple people to work together, thus delaying the overall production line schedule, but also the tilted or uneven hoisting can easily cause collisions, leading to equipment damage and posing safety hazards to nearby operators. Utility Model Content

[0004] One of the technical problems that this disclosure aims to solve is the safety hazard that exists during the transfer of fuel cell stacks.

[0005] To address the aforementioned technical problems, this disclosure provides a fuel cell stack transfer device, comprising a horizontally movable chassis, a lifting mechanism mounted on the chassis, a lifting platform mounted on top of the lifting mechanism, and a support platform mounted on the lifting platform. The lifting mechanism is capable of driving the lifting platform to move up and down relative to the chassis. The support platform is configured to support the fuel cell stack and is capable of horizontally moving relative to the lifting platform between a first position and a second position. In the first position, the support platform is completely located above the lifting platform, and in the second position, the support platform extends horizontally from the lifting platform.

[0006] In some embodiments, the support platform is provided with two first limiting blocks spaced apart along a first horizontal direction and two second limiting blocks spaced apart along a second horizontal direction, wherein the first direction is perpendicular to the second direction.

[0007] In some embodiments, the first limiting block can be adjusted in position relative to the support platform along the first direction, and the second limiting block can be adjusted in position relative to the support platform along the second direction.

[0008] In some embodiments, the lifting platform is provided with a guide rail, and the bottom of the support platform is provided with a slider that is slidably disposed on the guide rail.

[0009] In some embodiments, the guide rail is provided with a limiting hole, and a pluggable locking pin is provided in the limiting hole. The locking pin is used to restrict the horizontal movement of the support platform located at the first position relative to the lifting platform.

[0010] In some embodiments, the lifting platform is provided with two support bars that extend in a first horizontal direction and are parallel to each other, and the guide rails are respectively provided on the surfaces of the support bars that are opposite to each other.

[0011] In some embodiments, the lifting platform is provided with two blocks spaced apart along the first direction, and the bottom of the support platform is provided with a boss located between the two blocks. In the first position and the second position, the boss stops against the two blocks respectively.

[0013] In some embodiments, the chassis is provided with an upwardly extending handle.

[0014] In some embodiments, the lifting mechanism is a scissor-type telescopic mechanism.

[0015] Through the above technical solutions, the support platform can realize the lifting and horizontal movement of the fuel cell stack, and can move the fuel cell stack to other carriers more smoothly, realizing the translational transfer of the fuel cell stack, ensuring the safety of the fuel cell stack, and eliminating safety hazards to operators.

[0028] refer to Figure 1 and Figure 2 As shown, this solution provides a transfer device for a fuel cell stack, including a horizontally movable chassis 1, a lifting mechanism 4 disposed on the chassis 1, a lifting platform 5 disposed on top of the lifting mechanism 4, and a support platform 8 disposed on the lifting platform 5. The lifting mechanism 4 can drive the lifting platform 5 to move up and down relative to the chassis 1. The support platform 8 is configured to support the fuel cell stack and can move horizontally relative to the lifting platform 5 between a first position and a second position. In the first position, the support platform 8 is completely located above the lifting platform 5. In the second position, the support platform 8 extends horizontally from the lifting platform 5.

[0029] The chassis 1 can move horizontally on the ground or other supporting surfaces, thereby moving the fuel cell stack on the support platform 8. The chassis 1 can be pushed manually or driven by an electric drive unit.

[0030] The lifting mechanism 4 can drive the lifting platform 5 and the support platform 8 to move up and down. When it is necessary to move the fuel cell stack onto the support platform 8, the height of the support platform 8 and the lifting platform 5 can be lowered. When it is necessary to move the fuel cell stack on the support platform 8 to other locations, such as the electric vehicle 13, the lifting mechanism 4 can drive the lifting platform 5 and the support platform 8 to rise to a height that matches other structures.

[0031] The support platform 8 can move horizontally relative to the lifting platform 5, for example, it can be moved manually. When it is necessary to transfer the fuel cell stack to the electric vehicle 13, the support platform 8 can be moved from a first position to a second position, with the support platform 8 located above the electric vehicle 13. Then, the support platform 8 can be lowered to allow the protruding structure extending from the side of the fuel cell stack to be supported on the electric vehicle 13. Finally, the support platform 8 moves from the second position to the first position relative to the lifting platform 5, thus realizing the transfer of the fuel cell stack.

[0032] In this solution, the support platform 8 can move the fuel cell stack vertically and horizontally, allowing it to be moved more smoothly to other carriers, thus achieving the translational transfer of the fuel cell stack, ensuring its safety, and eliminating safety hazards to operators.

[0033] In some embodiments, the support platform 8 is provided with two first limiting blocks 9 spaced apart along a first horizontal direction and two second limiting blocks 10 spaced apart along a second horizontal direction, the first direction being perpendicular to the second direction. The fuel cell stack is disposed on the support platform 8, between the two first limiting blocks 9 and the two second limiting blocks 10. The first limiting blocks 9 restrict movement of the fuel cell stack along the first direction, and the second limiting blocks 10 restrict movement of the fuel cell stack along the second direction. The fuel cell stack is generally a cuboid structure, and the first limiting blocks 9 and the second limiting blocks 10 can respectively engage with the sides of the fuel cell stack to restrict its movement.

[0034] In some embodiments, the first limiting block 9 is adjustable in position relative to the support platform 8 along the first direction, and the second limiting block 10 is adjustable in position relative to the support platform 8 along the second direction. The position of the first limiting block 9 relative to the support platform 8 along the first direction is adjustable to accommodate fuel cell stacks of different sizes. The first limiting block 9 can be bolted to the support platform 8, and the support platform 8 can be provided with multiple bolt holes along the first direction. Fixing the first limiting block 9 to different bolt holes allows the first limiting block 9 to be located in different positions, with different distances between two first limiting blocks 9. The arrangement of the second limiting block 10 is similar to that of the first limiting block 9, and will not be repeated here.

[0035] In some embodiments, the lifting platform 5 is provided with a guide rail 11, and the bottom of the support platform 8 is provided with a slider 12 slidably mounted on the guide rail 11. The slider 12 can guide the support platform 8 to slide on the guide rail 11, reducing frictional resistance during movement.

[0036] In some embodiments, the guide rail 11 is provided with a limiting hole, and a removable locking pin is provided in the limiting hole. The locking pin is used to restrict the horizontal movement of the support platform 8 located in the first position relative to the lifting platform 5. The limiting hole can be located on the upper surface of the guide rail 11. After the locking pin is inserted into it, it can stop the support platform 8 located in the first position along the front side in the first direction, thereby restricting the support platform 8 from moving towards the second position. After the locking pin is removed, the support platform 8 can move relative to the lifting platform 5.

[0037] In some embodiments, the lifting platform 5 is provided with two support bars 6 extending in a horizontal first direction and parallel to each other, and guide rails 11 are respectively provided on the opposing surfaces of the support bars 6. (See reference) Figure 1 As shown, the support bar 6 is roughly formed into a strip structure with a quadrilateral cross section. Guide rails 11 are provided on the surfaces of the two support bars 6 facing each other. The support bar 6 can make the guide rails 11 form a gap with the upper surface of the lifting platform 5, allowing other components to be installed on the upper surface of the lifting platform 5 and the bottom surface of the support platform 8.

[0038] In some embodiments, the lifting platform 5 is provided with two stops 7 spaced apart along the first direction, and the bottom of the support platform 8 is provided with a boss located between the two stops 7. At the first position and the second position, the boss stops against the two stops 7 respectively. When the support platform 8 moves to the second position, the boss (not shown in the figure) on its bottom surface contacts one of the stops 7, which restricts its continued movement in the direction from the first position to the second position. When the support platform 8 moves to the first position, the boss contacts the other stop 7, which also restricts its continued movement in the direction from the second position to the first position.

[0039] In some embodiments, the bottom of the chassis 1 is provided with rollers 2. Four rollers 2 can be provided on the bottom surface of the chassis 1, and the rollers 2 can reduce the friction between the chassis 1 and the ground.

[0040] In some embodiments, the chassis 1 is provided with an upwardly extending handle 3. The handle 3 can be roughly shaped like a door, making it convenient for operators to push the transfer equipment to move using the handle 3.

[0041] In some embodiments, the lifting mechanism 4 is a scissor-type telescopic mechanism. The scissor-type telescopic mechanism can be electrically powered, with its lifting and telescopic movement driven by electricity.

[0042] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.
