Description

Technical Field

[0001] This utility model relates to the technical field of fuel tank arrangement, specifically a hoisting fixture for a large-capacity vehicle-mounted hydrogen supply system. Background Technology

[0002] Hydrogen fuel cells, as a method of utilizing hydrogen energy, have the advantages of high energy conversion efficiency. Furthermore, they offer convenient fuel acquisition and short refueling times, and their reaction process produces only water, making them environmentally friendly. The hydrogen fuel supply system, a crucial component of hydrogen fuel cells, primarily provides high-pressure hydrogen to the fuel cell stack, supplying the operating energy for the entire vehicle.

[0003] Traditional hydrogen supply system hoisting often involves installing lifting rings on the system, with the rings typically located at the top of the main longitudinal beam. This means the system can only be hoisted from the top, making the process quite difficult. Furthermore, for highly integrated systems, such as those with the vehicle cooling unit mounted on top of the hydrogen supply system, traditional lifting ring installation is no longer suitable.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. The hoisting device has a flexible hoisting position in the hydrogen supply system, which can meet the hoisting needs of various systems. Compared with traditional lifting rings, its arrangement position on the system is more flexible and less affected by the height of the hydrogen supply system.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-3As shown, this technical solution discloses a lifting fixture for a large-capacity vehicle-mounted hydrogen supply system, including a support end 1 and a lifting end 2. The support end 1 and the lifting end 2 are detachably connected. The support end 1 includes a support body 11, which is L-shaped. A weight-reducing hole 12 is provided at the bottom of the support body 11. A connecting bracket 13 is provided on one side of the support body 11, with the side of the connecting bracket 13 away from the support body 11 bent downwards. Several threaded holes are provided on the side of the support body 11. Through the threaded holes on one side of the support body 11, the support end 1 can be installed on the hydrogen supply system. This lifting fixture allows for flexible placement in the hydrogen supply system, meeting the lifting requirements of various systems. Compared with traditional lifting rings, its placement on the system is more flexible and less affected by the height of the hydrogen supply system. The weight-reducing hole 12 on the support body 11 can reduce the weight of the support end 1 while ensuring the strength of the support body 11. The angle of the connecting bracket 13 is not limited, as long as it serves as a limiting function, thus limiting the lifting end 2 and improving the limiting effect of the device.

[0022] This embodiment can be further configured such that: the support body 11 is provided with a number of reinforcing ribs 14, three of which are shown in the figure. The specific shape and structure can also be designed according to actual needs. The reinforcing ribs 14 and the support body 11 are welded together. The structure of the reinforcing ribs 14 can improve the strength of the support body 11.

[0023] This embodiment can be further configured such that: the lifting end 2 includes a lifting bracket 21 and a lifting ring 22, the lifting bracket 21 and the lifting ring 22 are detachably connected by a pin, the detachable connection facilitates the installation and connection of the lifting end 2, improves the installation efficiency of the tooling, and saves installation time.

[0024] This embodiment can be further configured such that the hoisting bracket 21 is C-shaped, and several threaded holes are provided on both sides of the hoisting bracket 21. The C-shaped configuration facilitates the installation of other structures on the inner side of the hoisting bracket 21, and the structure is simple and easy to operate.

[0025] This embodiment can be further configured as follows: a first limiting block 211 is provided on the hoisting bracket 21, and the first limiting block 211 is connected to the hoisting bracket 21 by screw threads. A limiting groove 212 is provided on the first limiting block 211, and a limiting plate 15 is provided at the bottom of the bracket body 11. The limiting plate 15 and the limiting groove 212 are used in conjunction. The limiting plate 15 and the limiting groove 212 can improve the connection tightness between the hoisting end 2 and the bracket end 1, and improve the stability of the tooling during hoisting. In addition, a second limiting block 23 is provided. Two second limiting blocks 23 are provided, and the two second limiting blocks 23 are respectively connected to the two sides of the hoisting bracket 21 by screw threads. The second limiting blocks 23 can prevent the bracket end 1 from moving left and right, and improve the connection stability between the bracket end 1 and the hoisting end 2. The addition of multiple limiting blocks makes the entire hoisting process more stable and more convenient.

[0026] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
