Start the motor, and the motor drives the driving shaft 3 to rotate through the reducer. When the driving shaft 3 rotates, it drives the driving sprocket to rotate. When the driving sprocket rotates, it drives the driven sprocket 7 to rotate through the plate chain 6.

[0023] like Figure 1 and Figure 5As shown, the frame 1 has two chain support assemblies, and the two chain support assemblies are respectively used to support the plate chains 6 on both sides. The chain support assembly includes two parallel square steel rails 8, and the length direction of the square steel rails 8 is the same as the conveying direction of the conveyor. An open track groove 81 is arranged on the surfaces of the two square steel rails 8 close to each other. The plate chain 6 includes a chain plate, a roller and a pin, and the chain plate is connected to the pin through the roller. Both ends of the pin of the plate chain 6 are rotatably mounted with a sleeve shaft 9, and the sleeve shafts 9 at both ends of the pin of the plate chain 6 are respectively arranged in the open track grooves 81 of the two square steel rails 8, and the rotation setting of the sleeve shaft 9 can effectively prevent wear. The chain plate of the plate chain 6 is in an L-shaped plate shape, the vertical part of the chain plate is connected to the roller of the plate chain 6, and the transverse part of the chain plate is used to connect the positioning support assembly 5. A plurality of positioning support assemblies 5 are arranged on the plate chain 6, and the positioning support assemblies 5 are used to support the aluminum alloy high-pressure composite gas cylinder by supporting the connecting rods connected to the bottle mouths at both ends of the aluminum alloy high-pressure composite gas cylinder, and at the same time, the aluminum alloy high-pressure composite gas cylinder can be supported to a certain height so that the aluminum alloy high-pressure composite gas cylinder will not collide with the driving shaft 3 and the driven shaft 4.

[0024] like Figure 2-Figure 4 As shown, the positioning support assembly 5 includes a U-shaped seat 55, a base frame 51 and a mounting frame 52. The U-shaped seat 55 is connected to the transverse part of the chain plate of the plate chain 6. The U-shaped seat 55 includes a transverse wall and vertical walls arranged at both ends of the transverse wall. A plurality of threaded through holes are arranged on each of the two vertical walls of the U-shaped seat 55, and a first fixing bolt 56 is arranged in each of the threaded through holes. The base frame 51 is located in the U-shaped seat 55 and is firmly fixed by the first fixing bolt 56. The mounting frame 52 is arranged on the base frame 51, and a bracket 53 is installed on the mounting frame 52. A vertical guide groove is arranged on the mounting frame 52, and the bracket 53 is arranged in the vertical guide groove of the mounting frame 52. The width of the bracket 53 is the same as the width of the vertical guide groove of the mounting frame 52. A threaded hole is provided on the wall of the vertical guide groove of the mounting frame 52, and a mounting through hole 531 is provided on the bracket 53. When the bracket 53 is set in the vertical guide groove of the mounting frame 52, the mounting through hole 531 is aligned with the threaded hole on the wall of the vertical guide groove, and a second fixing bolt 57 is installed in the threaded hole. The bracket 53 can be fixed by tightening the second fixing bolt 57. An adjustment threaded hole is provided on the mounting frame 52 below the bracket 53, and an adjustment bolt 58 is installed in the adjustment threaded hole.

Start the motor of the drive device 2, and the motor drives the driving shaft 3 to rotate through the reducer. When the driving shaft 3 rotates, it drives the driving sprocket to rotate. When the driving sprocket rotates, it drives the driven sprocket 7 to rotate through the plate chain 6. The movement of the plate chain 6 drives the positioning support component 5 to move, and then drives the aluminum alloy high-pressure composite gas cylinder supported by the positioning support component 5 to move, thereby achieving the transportation of the aluminum alloy high-pressure composite gas cylinder. When the plate chain 6 drives the aluminum alloy high-pressure composite gas cylinder to move through the positioning support assembly 5, since the sleeve shafts 9 are rotatably installed at both ends of the pin shaft of the plate chain 6, and the sleeve shafts 9 at both ends of the pin shaft of the plate chain 6 are respectively set in the open track grooves 81 of the two square steel tracks 8, the plate chain 6 is supported by the square steel tracks 8, which effectively improves the load-bearing capacity and can carry the aluminum alloy high-pressure composite gas cylinder. Moreover, the sleeve shafts 9 at both ends of the pin shaft of the plate chain 6 are rotatably set, which can effectively reduce wear and improve the service life of the utility model.

[0026] In summary, the utility model has a positioning support assembly 5 that can stably place the aluminum alloy high-pressure composite gas cylinder, and has the advantage of strong bearing capacity, and can achieve stable transportation of the aluminum alloy high-pressure composite gas.
