[0027] See Figures 1 to 8 , the present invention is a vertical rotary material conveying device with adjustable width, having a frame 6. On the frame, there are arranged in parallel a retractable chain conveying mechanism m3 and a retractable chain conveying mechanism n4. The structures of the retractable chain conveying mechanism m and the retractable chain conveying mechanism n are the same. The conveying chains in the retractable chain conveying mechanism m and the retractable chain conveying mechanism n are arranged in a way that they are aligned left and right and staggered in the vertical height position; there is also a synchronous driving mechanism 2, which drives the retractable chain conveying mechanism m and the retractable chain conveying mechanism n to achieve synchronous cyclic operation; there is also a circulating trolley mechanism 5 between the retractable chain conveying mechanism m and the retractable chain conveying mechanism n. The circulating trolley mechanism circulates together with the conveying chains in the retractable chain conveying mechanism m and the retractable chain conveying mechanism n. The retractable chain conveying mechanism m and the retractable chain conveying mechanism n are arranged parallel to each other front and back but staggered by a certain height in the vertical direction, where:

[0028] The structures of the retractable chain conveying mechanism m and the retractable chain conveying mechanism n are the same, and both include four steering sprockets and a closed-loop chain 17. The four steering sprockets are respectively a fixed steering sprocket 7, a movable steering sprocket a 10, a movable steering sprocket b 13, and a movable steering sprocket c 14. The four steering sprockets are arranged in a rectangle, and the closed-loop chain is wound around the four steering sprockets. Among them, the movable steering sprocket a is supported and installed by a vertical adjustment device, the movable steering sprocket b is supported and installed by a 45° oblique adjustment device, and the movable steering sprocket c is supported and installed by a horizontal adjustment device;

[0029] The circulating trolley mechanism has a supporting frame. Further, in this embodiment, the supporting frame has a frame body 18, and rows of supporting rollers 20 are installed on the frame surface. At the middle of the two sides of the supporting frame, there is a welding shaft 22 respectively. One end of one welding shaft is fixedly connected with a vertical plate A 21 vertically downward, and the end of the other welding shaft is fixedly connected with a vertical plate B 23 vertically upward. A transverse clamping shaft 24 is fixedly connected to the lower end of the vertical plate A and the upper end of the vertical plate B respectively. A chain connecting seat 19 is installed on each clamping shaft through a bearing 25. One of the chain connecting seats is fixedly connected to the conveying chain in the retractable chain conveying mechanism m, and the other chain connecting seat is fixedly connected to the conveying chain in the retractable chain conveying mechanism n.

[0030] Further, in the present invention, the vertical adjustment device has a vertical chute plate 8, and a vertically sliding slider a 9 is installed in the vertical chute plate. The slider a is connected to the axle of the movable steering sprocket a, and the slider a is driven by a vertical driving mechanism and moves up and down along the vertical chute plate for adjustment; the 45° oblique adjustment device has an oblique chute plate 11, and a 45° obliquely sliding slider b 12 is installed in the oblique chute plate. The slider b is connected to the axle of the movable steering sprocket b, and the slider b is driven by an oblique driving mechanism and moves obliquely at 45° along the oblique chute plate for adjustment; the horizontal adjustment device has a horizontal chute plate 15, and a horizontally sliding slider c 16 is installed in the horizontal chute plate. The slider c is connected to the axle of the movable steering sprocket c, and the slider c is driven by a horizontal driving mechanism and moves left and right along the horizontal chute plate for adjustment; further, in the present invention, the vertical driving mechanism, the oblique driving mechanism, and the horizontal driving mechanism are any one of a ball screw, a trapezoidal screw, and a linear slide rail guiding gear / chain / band.

[0031] The above chute plate and the corresponding slider are actually to open a chute on a long strip plate. The slider can slide flexibly in the chute. The movement of the slider can be driven by any one of a ball screw, a trapezoidal screw, and a linear slide rail guiding gear / chain / band. Their connection with the slider is relatively simple and easy to achieve, and it is also a very common transmission method in actual mechanical transmission. For example, a ball screw can be inserted into the slider, and the rotation of the screw can drive the slider to move in the chute.

[0032] Furthermore, the synchronous drive mechanism described in this embodiment has a synchronous motor 29, the output end of the synchronous motor is connected to a bidirectional output reducer 28, and the bidirectional output reducer is connected to a synchronous shaft 27 on each output side, and each end of each synchronous shaft is connected to the wheel axle of the fixed steering sprocket 7 on the corresponding side through a set of transmission sprocket chain mechanisms 26 and drives the corresponding fixed steering sprocket to rotate.

[0033] Furthermore, the bearing mounted on the pallet shaft in this embodiment is a deep groove ball bearing; the chain connecting seat is an ear plate structure, and the chain connecting seat and the corresponding conveying chain are connected with screws.

[0034] The synchronous drive mechanism of the present invention comprises a synchronous motor composed of a single motor with a hollow shaft, a synchronous shaft with bidirectional output, and a sprocket chain transmission, thereby ensuring synchronous driving of two closed-loop chains, namely, double chains.

[0035] See also Figure 4 , retractable chain conveyor mechanisms m and n: are both composed of 4 steering sprockets, one of which is a fixed steering sprocket with a relatively fixed position, the movable steering sprocket c can move horizontally, and the movement method can be adjusted by ball screw, trapezoidal screw, linear slide guide gear / chain / belt and other transmission horizontal reciprocating adjustment, the movable steering sprocket a can move vertically, and the movement method can be adjusted by ball screw, trapezoidal screw, linear slide guide gear / chain / belt and other transmission vertical reciprocating adjustment, the movable steering sprocket b is a slidable steering tensioning sprocket, which is adjusted by moving the slider up and down 45°. No matter how the four steering sprockets are adjusted, they are always arranged in a rectangular shape. The total length of the closed-loop chain is unchanged, that is, the circumference remains unchanged, as shown in the figure X+Y=constant value, so when adjusting, according to the loading requirements of the carriage width of different trucks, the Y value in the figure can be adjusted in advance to adapt to the width requirements of the carriage. After the adjustment, the circulating trolley mechanism will also move accordingly.

[0036] Circulating trolley mechanism: The two ends of the supporting frame are respectively connected to two closed-loop chains, which are staggered up and down and can rotate individually. Through the synchronization of the closed-loop chains on both sides, it is ensured that the points where the supporting frame (both ends) are connected to the chains are always in a vertical state, so that the vertical plates A and B at both ends are always in a vertical state up and down, thereby ensuring that the vertical plates and welding shafts connected to the frame are always vertical, thereby ensuring that the supporting frame is always level and preventing the material from falling.

[0037] See attached Figure 5 , 6As can be seen from 7, no matter where the chain connection seats move along with their respective closed-loop chains, since the two closed-loop chains are misaligned and the two vertical plates are also vertically misaligned, a force will be formed, causing the vertical plates A and B to always remain vertical. In this way, the supporting frame will always remain horizontal and will not tip over, and the goods above will always remain in a stable state of cyclic transportation.

[0038] As the goods are conveyed from one side to the other in a cycle along with the closed-loop chain, the stacking personnel can cooperate on both sides and use the conveying equipment of the present invention for loading or unloading operations, which is efficient and fast.

[0039] The present invention has a wide range of applications, can support the loading of trucks with fixed wall panels, and supports vehicle models of different widths;

[0040] The present invention has a fast conveying rhythm. Compared with the loading of other similar RGV transfer methods on the market, this robot can match the speed of the front-end delivery and conveying, and operates in a pipeline manner, improving the operation efficiency.

[0041] The structure of the present invention is simple and compact, which is convenient for maintenance.
