For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] The present embodiment relates to a lifting device for fuel cell assembly, which can help improve the efficiency of workpiece lifting and assembly during the fuel cell system assembly process, and at the same time, can also reduce the use of manpower and improve the safety of the overall operation.

[0046] In terms of overall structure, Figures 1 to 11As shown, the fuel cell assembly hanger of this embodiment includes a base frame 1, a hanging shaft 2 arranged on the base frame 1, and a clamping assembly 3 arranged at two opposite ends of the base frame 1. The hanging shaft 2 is adjustable in height direction of the base frame 1, and a driving rod 21 located above the base frame 1 is arranged on the hanging shaft 2.

[0047] Furthermore, each clamping assembly 3 includes a connecting rod assembly 31 hingedly arranged on the base frame 1 , and connecting parts and clamping claws 32 arranged at both ends of the connecting rod assembly 31 . The clamping claws 32 are located below the base frame 1 , and the connecting parts are transmission-connected to the driving rod 21 .

[0048] At this time, as set above, by adjusting the position of the lifting shaft 2 along the height direction of the base frame 1, and based on the transmission connection between each connecting part and the driving rod 21, when the position of the lifting shaft 2 is adjusted, it can drive each connecting rod assembly 31 to rotate around the corresponding hinge point through the driving rod 21 and the connecting part to form the opening and closing of each clamping claw 32, thereby realizing the clamping and lifting of the workpiece, reducing the use of manual labor, and improving the efficiency and safety of the lifting and assembly of the workpiece during the assembly of the fuel cell system, and has high practicality.

[0049] Based on the overall introduction above, in detail, in this embodiment, in a specific implementation, the driving rod 21 can be threadedly connected to the hoisting shaft 2 along the radial direction of the hoisting shaft 2 to facilitate the disassembly and replacement of the driving rod 21. At the same time, the fuel cell assembly hanger is used for hoisting and assembling various subcomponents in the fuel cell, especially for hoisting and assembling DCDC.

[0050] Furthermore, it should be noted that the expressions related to directions in this embodiment are only exemplary descriptions of this embodiment. In specific implementation, the expressions of directions in this embodiment vary with the different directions in which the fuel cell assembly hanger is set, that is, the directions in this embodiment refer to a relative coordinate system based on the fuel cell assembly hanger.

[0051] In this embodiment, as a preferred implementation form, Figure 1 and Figure 2 As shown, along the height direction of the base frame 1, the hanging shaft 2 is slidably arranged on the base frame 1, and a locking assembly 4 is arranged between the hanging shaft 2 and the base frame 1. Such an arrangement can facilitate the realization of a position adjustable design of the hanging shaft 2 along the height direction of the base frame 1, and the structure and operation are simple and practical.

[0052] In the specific implementation, in this embodiment, as a preferred implementation form, combined with Figure 1 and Figure 5As shown, a mounting cylinder 11 is provided on the base frame 1, and the hanging shaft 2 is slidably arranged in the mounting cylinder 11. At the same time, the locking assembly 4 includes a base 41 arranged on the mounting cylinder 11, and a fastening assembly 42 arranged on the base 41, and the fastening assembly 42 locks the hanging shaft 2 in the mounting cylinder 11.

[0053] Here, the arrangement of the mounting cylinder 11 is conducive to improving the sliding stability of the hoisting shaft 2, and the locking assembly 4 includes a base 41 and a fastening assembly 42, so that the structure is simple and practical, and the locking reliability is high.

[0054] Of course, to ensure the reliability of the lifting, see Figure 3 As shown, the top of the lifting shaft 2 of this embodiment is provided with a lifting ring 23 for lifting, and the bottom thereof is preferably also provided with a second limiting member 24 for limiting the lifting shaft 2 from separating from the base frame 1. Specifically, the second limiting member 24 is located below the base frame 1.

[0055] Secondly, in this embodiment, as a preferred implementation form, see Figure 3 and Figure 4 As shown, the hoisting shaft 2 is provided with a first long hole 22 arranged along the height direction of the base frame 1, and the mounting tube 11 is provided with a mounting hole 111. Figure 6 and Figure 7 As shown, the fastening assembly 42 includes a guide rod 421 disposed on the base 41, a first limit member 424 threadedly disposed on one end of the guide rod 421, a sleeve 422 sleeved on the guide rod 421, and an elastic member 423 disposed between the sleeve 422 and the guide rod 421.

[0056] Furthermore, the guide rod 421 is inserted into the first elongated hole 22 and the mounting hole 111 , the first stopper 424 and the elastic member 423 are respectively arranged on both sides of the mounting tube 11 , and the elastic member 423 presses the hoisting shaft 2 tightly in the mounting tube 11 through the sleeve 422 .

[0057] The main advantage of such a setting is that, through the coordinated use of the first long hole 22, the mounting hole 111 and the fastening assembly 42, the position adjustment of the lifting shaft 2 along the height direction of the base frame 1 can be realized. At the same time, the fastening assembly 42 includes a guide rod 421, a first limit member 424, a sleeve 422 and an elastic member 423. The elastic force of the elastic member 423 can be adjusted by adjusting the relative position of the first limit member 424 on the guide rod 421, so as to facilitate the locking or unlocking of the lifting shaft 2 by the sleeve 422, and has a higher locking convenience.

[0058] In a specific implementation, the guide rod 421 is slidably arranged on the base 41 along the radial direction of the mounting tube 11, and the sleeve 422 is preferably provided with a top portion for tightening the lifting shaft 2, and an extension portion arranged at one end of the top portion close to the first limit member 424 to enhance the sliding stability of the sleeve 422.

[0059] To facilitate the operation of the fastening assembly 42, the present embodiment also preferably provides an operating member 425 at the end of the guide rod 421 away from the first limiting member 424. The elastic member 423 can be a spring provided between the operating member 425 and the sleeve 422, and the spring is also sleeved on the guide rod 421. The above-mentioned operating member 425 can be, for example, an operating handle well known to those skilled in the art, and the first limiting member 424 can be, for example, block-shaped.

[0060] Specifically, when the hoisting shaft 2 needs to be adjusted, the first limiting member 424 can be fixed first, and then the guide rod 421 can be rotated out relative to the first limiting member 424 by the operating member 425, that is, the first limiting member 424 is adjusted along the end away from the elastic member 423, so that the guide rod 421 can move radially along the installation tube 11 in a larger range, and the elastic force of the elastic member 423 on the sleeve 422 is weakened, so that when the hoisting shaft 2 is pulled hard, the hoisting shaft 2 can overcome the elastic force of the elastic member 423 and break free from the restraint of the sleeve 422, and then the position of the hoisting shaft 2 can be adjusted;

[0061] When the hoisting shaft 2 is adjusted into place, at this time, the operating member 425 is screwed into the guide rod 421 relative to the first limit member 424, that is, the first limit member 424 is adjusted along the end close to the elastic member 423, so that the radial movement range of the guide rod 421 along the mounting tube 11 becomes smaller, and the elastic force of the elastic member 423 on the sleeve 422 is increased, so that when the hoisting shaft 2 is pulled with force, the hoisting shaft 2 cannot overcome the elastic force of the elastic member 423, and cannot break free from the tightening and restraint of the sleeve 422, thereby achieving the locking of the hoisting shaft 2.

[0062] Of course, in addition to being set as the above-mentioned structural form, the locking assembly 4 of this embodiment may also adopt a locking structure well known to those skilled in the art, for example, a first elongated hole 22 is set on the mounting tube 11, and a mounting through hole 111 corresponding to the first elongated hole 22 is set on the lifting shaft 2, and the locking fixation between the lifting shaft 2 and the mounting tube 11 is achieved by means of bolts passing through the first elongated hole 22 and the mounting through hole 111.

[0063] In addition, in this embodiment, as a preferred implementation form, combined with Figure 1 , Figure 2 and Figure 8 As shown, each connecting rod assembly 31 includes a first connecting rod 311 and a second connecting rod 312 connected together. In addition, the connecting portion is provided on the first connecting rod 311, the clamping jaw 32 is provided on the second connecting rod 312, and the connecting point between the first connecting rod 311 and the second connecting rod 312 is hingedly provided on the base frame 1.

[0064] Each connecting rod assembly 31 includes a first connecting rod 311 and a second connecting rod 312 , and the connection point between the first connecting rod 311 and the second connecting rod 312 is hinged on the base frame 1 , which is conducive to driving the opening and closing of each clamping jaw 32 through the driving rod 21 .

[0065] In the specific implementation, in this embodiment, as a preferred implementation form, each connecting portion includes a second elongated hole 3111 provided on the first connecting rod 311, and the second elongated hole 3111 extends along the length direction of the first connecting rod 311. At the same time, the driving rod 21 is inserted into each elongated hole. Therefore, it is convenient to realize the transmission cooperation between the driving rod 21 and each first connecting rod 311, and the structure is simple and reliable.

[0066] To ensure the clamping stability of the clamping assembly 3, in this embodiment, as a preferred implementation form, a reinforcement structure is provided between the clamping jaw 32 and the second connecting rod 312 to facilitate improving the connection strength between the clamping jaw 32 and the second connecting rod 312, and the reinforcement structure can be specifically as follows: Fig. 9 As shown, a reinforcing plate 33 is included between the clamping jaw 32 and the second link 312 .

[0067] Among them, the clamping jaw 32 of this embodiment is still as Fig. 9 As shown in , it can be L-shaped in overall visual sense, and includes a transverse rod 321 connected to the second connecting rod 312 and extending along the width direction of the base frame 1, and side connecting rods 322 arranged at both ends of the transverse rod 321, and a clamping plate 323 is arranged between the two side connecting rods 322 to facilitate the clamping of the workpiece. At the same time, the above-mentioned reinforcement plates 33 are preferably arranged on both sides of the second connecting rod 312 along the width direction of the base frame 1, so as to achieve a better structural reinforcement effect.

[0068] At this time, see Figure 8 and Fig.10 As shown, in this embodiment, which is also a preferred implementation form, a detachable clamping pad 34 is provided on the clamping jaw 32 to facilitate replacement of the suitable clamping pad 34 according to different types of workpieces, thereby improving the versatility of the fuel cell assembly hanger.

[0069] In specific implementation, the clamping pad 34 follows the clamping part of the workpiece to improve the clamping stability. For example, when the workpiece is a DCDC, the clamping part is a boss on the periphery of the DCDC, and bolts are arranged on the boss. The clamping pad 34 can be provided with an avoidance hole for avoiding the bolts.

[0070] In addition, in this embodiment, as a preferred implementation form, Figure 1 and Figure 2 As shown, the base frame 1 is provided with a first positioning component 5 for positioning the top of the workpiece to be clamped, and a second positioning component 6 for positioning the side of the workpiece to be clamped, so as to improve the convenience and safety of the lifting process.

[0071] Furthermore, as a preferred implementation form, the first positioning assembly 5 of this embodiment includes a positioning rod 51 arranged along the height direction of the base frame 1, and a positioning block 52 provided on the top of the positioning rod 51, the positioning block 52 is used to abut against the workpiece, and the positioning rod 51 is screwed to the base frame 1. Such an arrangement can realize the position adjustment of the height direction of the positioning rod 51, and is thus suitable for the hoisting of workpieces of different models, which is conducive to the improvement of versatility.

[0072] At the same time, in this embodiment, as a preferred implementation form, two first positioning components 5 are arranged on the base frame 1, and the two first positioning components 5 are respectively arranged on both sides of the width direction of the base frame 1. The advantage of this arrangement is mainly that it is conducive to improving the positioning accuracy and hoisting stability of the workpiece in the height direction of the base frame 1.

[0073] Moreover, in the specific structure, the base frame 1 of this embodiment is also provided with mounting rods 12 corresponding to each first positioning component 5, each mounting rod 12 is extended along the width direction of the base frame 1, and each first positioning component 5 is respectively arranged on the base frame 1 through the corresponding mounting rod 12.

[0074] In addition, in this embodiment, as a preferred implementation form, Fig.11 As shown, the second positioning assembly 6 includes a connecting plate 61 disposed on the base frame 1, and a positioning plate 62 disposed on the connecting plate 61. The connecting plate 61 is positionally adjustable along the length direction of the base frame 1, and the positioning plate 62 is positionally adjustable along the height direction of the base frame 1.

[0075] It can be understood that the connecting plate 61 in the second positioning assembly 6 is adjustable along the length direction of the base frame 1, and the positioning plate 62 is adjustable along the height direction of the base frame 1, which is conducive to adjusting the side positioning position, thereby facilitating improving versatility.

[0076] Of course, the second positioning components 6 of this embodiment are preferably arranged as two spaced apart along the length direction of the base frame 1, so as to provide a better side positioning effect for the workpiece, and in this embodiment, according to the positioning requirements of the side of the workpiece, only the connecting plate 61 can be set to be adjustable in the length direction of the base frame 1, or only the positioning plate 62 can be set to be adjustable in the height direction of the base frame 1.

[0077] In specific implementation, the connecting plate 61 may preferably be L-shaped, with its transverse portion connected to the bottom of the base frame 1, and a third elongated hole 611 extending along the length direction of the base frame 1 is provided on the transverse portion, and a first matching hole corresponding to the third elongated hole 611 is provided on the base frame 1, and bolts are passed through the third elongated hole 611 and the first matching hole, thereby realizing the connection between the connecting plate 61 and the base frame 1, and the position of the connecting plate 61 relative to the base frame 1 is adjustable.

[0078] Similarly, the positioning plate 62 can adopt a connection method similar to that of the connecting plate 61. Specifically, the positioning plate 62 is connected to the longitudinal portion of the connecting plate 61, and a fourth elongated hole 621 extending along the height direction of the base frame 1 can be provided on the positioning plate 62, and a second matching hole corresponding to the fourth elongated hole 621 is provided on the connecting plate 61. Bolts are passed through the fourth elongated hole 621 and the second matching hole to realize the connection between the positioning plate 62 and the connecting plate 61, and the position of the positioning plate 62 relative to the connecting plate 61 is adjustable.

[0079] It is worth mentioning that see Figure 4 As shown, the base frame 1 of this embodiment is also provided with a handle 13 for operating the entire fuel cell assembly hanger. The handle 13 can be arranged on the mounting tube 11 through a first mounting block 131 and a second mounting block 132 that are interlocked with each other, and the first mounting block 131 and the second mounting block 132 can be connected by bolts. The handle 13 can be arranged on the first mounting block 131 or the second mounting block 132.

[0080] The fuel cell assembly hanger of the present embodiment makes the lifting shaft 2 adjustable in the height direction of the base frame 1, and the connecting portion of each clamping assembly 3 is connected to the driving rod 21 by transmission. When the lifting shaft 2 is adjusted in the height direction of the base frame 1, the driving rod 21 and the connecting portion can drive each connecting rod assembly 31 to rotate around the corresponding hinge point to form the opening and closing of each clamping claw 32, thereby achieving clamping and lifting of the workpiece, reducing manual labor, and improving the efficiency and safety of workpiece lifting and assembly during the assembly of the fuel cell system, and has a good use effect.

[0081] Moreover, based on the coordinated use of components such as the first elongated hole 22, the second elongated hole 3111, the first positioning assembly 5, the second positioning assembly 6 and the clamping pad 34, the fuel cell assembly hoist can also be used for hoisting operations of workpieces of different types, thereby helping to improve its versatility.
