The first guide rail 1, the second guide rail 2, the third guide rail 3 and the transmission rail 4 are respectively closed.

In the embodiment of the invention, since the first clamping part 72 is clamped between the first guide rail 1 and the second guide rail 2, the second clamping part 73 is clamped between the third guide rail 3 and the transmission rail 4, and the second clamping part 73 can move along the transmission rail 4, the first clamping part 72 can be driven to move along the first guide rail 1 and the second guide rail 2 through the engagement of the second clamping part 73 and the transmission rail 4, and the carrying vehicle body 6 is driven to move, so that the carrying unit 5 is moved. Therefore, the carrying vehicle body 5 can continuously move along the guide rails (the first guide rail 1, the second guide rail 2, the third guide rail 3 and the transmission rail 4), and if the guide rails are closed guide rails, the carrying vehicle body 5 can circularly move along the guide rails and can vertically move or horizontally move, so that the carrying efficiency of the carrying device is improved.

It should be noted that the shape of the guide rail is not limited in the embodiment of the present invention, and the guide rail may be quadrangular, pentagonal, hexagonal, etc., or elliptical, lumbar, circular, etc. Generally, the shapes of the guide rails are calculated according to the actual conveying requirement, and the shapes of the first guide rail 1, the second guide rail 2, the third guide rail 3 and the transmission rail 4 are calculated by combining the limiting member 71, the first clamping portion 72 and the second clamping portion 73.

As shown in fig. 1 to 3, the number of the carrying units 5 may be plural, and the carrying units 5 may move horizontally and vertically in the first rail 1, the second rail 2, the third rail 3, and the transmission rail 4 by the first engaging portion 72 and the second engaging portion 73, respectively. Since one moving mechanism 7 is provided on each of both sides of the conveyance vehicle body 6, two sets of guide rails (including the first guide rail 1, the second guide rail 2, the third guide rail 3, and the transmission rail 4) are required, the conveyance vehicle body 6 can circularly convey the object, and the object can be conveyed to different heights by the conveying device on the conveyance vehicle body 6. The number of the carrying units 5 can be increased or decreased according to the requirements, and the configuration is flexible; each carrying unit 5 moves individually, shares a guide rail, and cyclically lifts or lowers the object to a specified position.

The limiting member 71 may be rod-shaped, so that the first clamping portion 72 is always clamped between the first guide rail 1 and the second guide rail 2, and the second clamping portion 73 is always clamped between the third guide rail 3 and the transmission rail 4, thereby improving stability of the conveying device.

Optionally, the diameter of the second guide wheel 731 is larger than the diameter of the gear 732.
