Relying on the action of gravity, the wheel hub and the counterweight plate 51 are pressed against the support belt 3. At this time, the connecting rope 6 is in a straightened state, and the elastic compression amount is small; the support belt 3 is wrapped around the outside of the wheel hub and the counterweight plate 51, and the support belt 3 supports and limits the wheel hub. In addition, the support belt 3 is fixedly set on the support seat 2, and the support seat 2 is arranged on the suspension conveyor line 1, so the suspension conveyor line 1 can drive the conveying hub to move.

[0058] Since the support belt 3 is wrapped around the outside of the wheel hub and the counterweight plate 51, the protection of the conveying wheel hub can be improved; when the number of support seats 2 is large and the distance between two adjacent support seats 2 is close, direct collision between two adjacent wheel hubs can also be avoided during the conveying process.

[0059] A first guide pulley 21 and a second guide pulley 22 are provided on the support seat 2; the connecting rope 6 passes around the first guide pulley 21 and the second guide pulley 22, and the two ends of the connecting rope 6 are respectively fixed on the support seat 2 and the fixed block 83, the second guide pulley 22 is close to one end of the connecting rope 6 connected to the support seat 2, and the first guide pulley 21 is close to the support block 82, and the first guide pulley 21 and the second guide pulley 22 both play a guiding role for the connecting rope 6.

[0060] A first opening 31 and a second opening 32 are provided on the support belt 3, the first opening 31 extends to one end of the support belt 3 connected to the hook 41, and the first opening 31 is located between the two hooks 41, and the second opening 32 extends to one end of the support belt 3 fixedly connected to the support seat 2; the first opening 31 and the second opening 32 correspond in position, and the second guide pulley 22 and the second opening 32 correspond in position; the portion of the connecting rope 6 located between the first guide pulley 21 and the second guide pulley 22 bypasses the limiting wheel 71 and forms two strands, and the portion of the connecting rope 6 located between the first guide pulley 21 and the second guide pulley 22 corresponds in position to the first opening 31 and the second opening 32.

[0061] See also Figure 1-Figure 8In this embodiment, the wheel hub is supported and covered by the support belt 3, and the wheel hub is driven to the installation area by controlling the suspension conveyor line 1. When the wheel hub reaches the installation area, and the wheel hub, the support belt 3, etc. are in a stationary state, the wheel hub is located above the side of the rear axle of the electric tricycle to be assembled, as shown in FIG. Figure 7 The state shown; when the two hooks 41 are respectively separated from the first hanging strip 42 and the second hanging strip 43, and the support belt 3 is naturally hung down, under the action of gravity, the wheel hub, the limiting slide cylinder 7, the counterweight plate 51, etc. move downward, and drive the connecting rope 6 to move, and pull the end of the connecting rope 6 connected to the fixed block 83 to move toward the support block 82, causing further compression of the spring 84; by setting the weight of the counterweight plate 51, the limiting slide cylinder 7 and the support column 5 are kept in a horizontal state; as the wheel hub, the limiting slide cylinder 7, the counterweight plate 51, etc. continue to move downward, the compression deformation of the spring 84 gradually increases. Due to the provision of the spring 84, the connecting rope 6, the wheel hub, etc. no longer continue to move downward after moving a certain distance downward. At this time, the wheel hub is just located on the upper side of the rear axle end of the electric tricycle, and the center of the wheel hub is slightly higher than the center of the rear axle end of the electric tricycle, that is, Figure 8 In the state shown, due to the action of the connecting rope 6, the wheel hub is in a suspended state. By holding the outer ring of the wheel hub and applying a certain downward force to the wheel hub, the wheel hub can be easily moved close to the end of the rear axle of the electric tricycle. Since the wheel hub is sleeved on the outside of the limiting slide 7, the wheel hub moves and rotates along the limiting slide 7, and since the support column 5 and the limiting slide 7 are movably connected through the bearing, the limiting slide 7 can rotate, thereby facilitating the rotation of the wheel hub, that is, facilitating the alignment of the mounting hole on the wheel hub with the screw on the rear axle of the electric tricycle that matches the mounting hole, thereby facilitating the manual assembly of the wheel hub to the rear axle of the electric tricycle.

[0062] During the assembly of the wheel hub, there is no need to hold the wheel hub by hand to overcome the overall gravity of the wheel hub. You only need to press down to overcome the elastic force of the spring 84. The spring 84 is made of a suitable material, so you can hold the wheel hub by hand and apply less downward force to achieve the assembly of the wheel hub, thereby achieving the effect of saving time and effort.

[0063] In order to reduce the interference and influence on the hand-held operation of the wheel hub, a notch 511 is provided on the counterweight plate 51 .
