[0019] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0020] Example: A loading and unloading conveying device, such as Figures 1-4As shown, the system includes four columns 11, with two columns 11 forming a group. A small beam 12 is installed at the top of each group. An equipment frame 13 is installed between the small beams 12 on both sides. A first carriage 21 is installed on the top of the equipment frame 13. A top frame 23 is installed on the top of the carriage. A first upper idler wheel assembly 241 is installed on the top of the top frame 23. Multiple top screw assemblies 33 are installed on the top of the top frame 23. A sprocket assembly 242 is installed on the top of the first carriage 21 corresponding to the top screw assembly 33. An extension frame 29 extends to one side of the top of the first carriage 21. A second carriage is slidably installed on one side of the top of the extension frame 29. 25. A second upper idler wheel assembly 243 is provided on the top of the second carriage 25. A platform 32 is provided below the first carriage 21. A scissor lift platform 3 is provided between the platform 32 and the first carriage 21. A bottom screw assembly 34 is provided on the platform 32. A pull rope for limiting the position passes through the top of the top screw assembly 33, along the first upper idler wheel assembly 241 and the second upper idler wheel assembly 243, and passes down through the bottom of the second carriage 25. It then passes through the sprocket assembly 242 and continues downward to connect with the bottom screw assembly 34. A loose plate lifting device 4 is provided at the bottom of the platform 32. The surface of the loose plate lifting device 4 holds a large loose plate of raw material 5.
[0021] The top of both the left and right sides of the equipment frame 13 is provided with a first slide rail 14. Both ends of the first slide rail 14 are provided with a stop frame 15. The bottom of the first slide 21 is slidably mounted on the first slide rail 14 by a slider. The four corners of the first slide 21 are provided with a buffer 22. Two side frames 264 are provided on one side of the first slide 21. A first reduction motor 26 is provided on one side frame 264. A coupling 261 is provided on the output end of the first reduction motor 26. A rotating shaft 262 is horizontally arranged inside the output end of the coupling 261. The other end of the rotating shaft 262 is mounted on the other side frame 264 through a shaft seat. Gears 263 are respectively sleeved on both ends of the rotating shaft 262. A rack 17 is provided on the inner side of the equipment frame 13 above the gear 263. The rack 17 is laid along the length of the inner side of the equipment frame 13.
[0022] The first slide 21 drives the output shaft 262 to rotate via the first reduction motor 26 on the rear side. At the same time, the gears 263 located at both ends of the shaft 262 rotate synchronously. The gears 263 mesh with the racks 17 fixed to both sides of the equipment frame 13 at the top, so that the first slide 21 can slide left and right on the top of the equipment frame 13 via the first slide rail 14. The stop frames 15 located on both sides of the first slide rail 14 are used to limit the movement of the first slide 21.
[0023] A second geared motor 27 is installed on one side of the top of the first slide 21. The output end of the second geared motor 27 is connected to a lead screw 271. The lead screw 271 extends to one side along the middle position of the extension frame 29 and its end is mounted on the extension frame 29 through a bearing seat. A lead screw seat 251 is threadedly connected to the surface of the lead screw 271. The top of the lead screw seat 251 is installed at the bottom of the second slide 25. Second slide rails 291 are provided on both sides of the top of the extension frame 29. The second slide 25 is slidably mounted on the slide rails by a slider. The second slide 25 is sleeved on the surface of the lead screw 271 through the bottom lead screw seat 251. The two sides of the second slide 25 slide against the top of the extension frame 29 through the second slide rails 291. The lead screw 271 is driven to rotate by the second geared motor 27 on one side, so that the second slide 25 can slide on the extension frame 29.
[0024] The bottom of one side of the scissor lift platform 3 is hinged to the platform 32. The bottom of the other side of the scissor lift platform 3 is slidably connected to the platform 32 via a third slide rail 31, so that the scissor lift platform 3 can lift the bottom platform 32 up and down without affecting the movement of the scissor lift platform 3.
[0025] A cross limit switch 28 is provided on one side of the first slide 21. At both ends of the equipment frame 13 corresponding to the cross limit switch 28, there are two lever brackets 281. The two lever brackets 281 are set to the distance of the maximum linear travel of the first slide 21. When the first slide 21 moves left or right, the cross limit switch 28 on one side touches the lever bracket 281 and the first slide 21 stops moving.
[0026] The principle of this utility model is as follows: by turning on the first reduction motor 26, it drives the rotating shaft 262 on the output end to start rotating. The gears 263 at both ends of the rotating shaft 262 mesh with the rack 17 on the top fixed and equipment frame 13, so that the first slide 21 can slide along the first slide rail 14 to the other side until the cross limit switch 28 on one side contacts one of the toggle brackets 281 to move the cross limit switch 28, thereby stopping the first reduction motor 26.
[0027] Next, the second reduction motor 27 starts, driving the lead screw 271 at the output end to rotate. The lead screw seat 251 on the surface of the lead screw 271 drives the second slide 25 to retract towards the top frame 23 via the second slide rail 291. At this time, the second upper idler wheel assembly 243 on the second slide 25 causes the tension rope on its surface to lose tension, thereby causing the bottom platform 32 to lower. As it lowers, the two sets of scissor lift platforms 3 between the platform 32 and the first slide 21 descend synchronously, stabilizing the descent of the platform 32. The bottom tray lifting device 4 is inserted into the large tray raw material 5 to lift it. Then the second reduction motor 27 is turned on, causing the second slide 25 to move to the other side again. The tension rope is stretched by the second upper idler wheel assembly 243, causing the bottom platform 32 to be lifted upward. After the second slide 25 moves to the other end, the first reduction motor 26 is turned on, causing the first slide 21 to move to the other side until the cross limit switch 28 contacts the toggle block frame 281 on the other side, completing one transport cycle.
[0028] Finally, it should be noted that the above embodiments are merely representative examples of this utility model. Obviously, this utility model is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model should be considered to fall within the protection scope of this utility model.
