DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will further describe the present application in detail with reference to the attached Figure 1 - Figure 4 drawings.

[0019] Embodiment 1:

[0020] A warehousing and logistics lifting and conveying device, including a base 1. Both outer walls of the base 1 are rotatably connected with first lifting rods 5. The outer walls of the first lifting rods 5 are hingedly connected with second lifting rods 6. Above the second lifting rods 6 is a connecting frame 17, and the connecting frame 17 is hingedly connected with the second lifting rods 6 on both sides. The inner walls of the two second lifting rods 6 are rotatably connected with driving blocks 7. By controlling the distance between the two driving blocks 7, the first lifting rod 5 and the second lifting rod 6 can be contracted or expanded, thereby controlling the rise or fall of the device, facilitating the loading and unloading of items. Between the two driving blocks 7 is a bidirectional lead screw 8, and the bidirectional lead screw 8 is threadedly connected with the two driving blocks 7. The threads on both sides of the bidirectional lead screw 8 are symmetrically and oppositely arranged. The threads between the bidirectional lead screw 8 and the two driving blocks 7 can achieve self-locking, and the self-locking condition of the thread depends on the helix angle of the thread, the friction coefficient, and the load received. The self-locking condition of the thread can be calculated by the following formula: self-locking condition = friction coefficient × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above content is all prior art, and in actual applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated here. By driving the bidirectional lead screw 8 to rotate, the two driving blocks 7 can be driven to move, thereby changing the distance between the two driving blocks 7, facilitating the lifting of the device. The outer wall of the connecting frame 17 is fixedly connected with a load-bearing seat 9. Both outer walls of the load-bearing seat 9 are provided with conveyor belts 11. A driving wheel is arranged inside the conveyor belt 11. Through the conveyor belts 11 on both sides, it is convenient to convey items, thereby improving the loading and unloading efficiency of items. And a transmission component is arranged between the two conveyor belts 11 of the load-bearing seat 9. Through the transmission component, it is convenient to synchronously drive the driving wheels, thereby realizing the smooth operation of the two conveyor belts 11.

[0021] Among them, the transmission component includes a transmission shaft 16. The two conveyor belts 11 are transmission-connected through the transmission shaft 16. The outer wall of the load-bearing seat 9 on one side of the transmission shaft 16 is fixedly connected with a support frame 13, and both the support frame 13 and the outer wall of the transmission shaft 16 are provided with sprocket discs 14. A chain 15 is arranged between the two sprocket discs 14, and the chain 15 is engaged with the two sprocket discs 14. One of the sprocket discs 14 is rotatably connected with the support frame 13, and the other sprocket disc 14 is fixedly connected with the transmission shaft 16. Thus, by driving the sprocket disc 14 rotatably connected to the support frame 13 to rotate, it can synchronously drive the sprocket disc 14 located on the transmission shaft 16 to rotate through the chain 15, thereby completing the rotation of the transmission shaft 16, and the transmission shaft 16 synchronously drives the driving wheels adapted to the conveyor belts 11 on both sides to rotate, completing the drive of the conveyor belts 11.

[0022] Both outer walls of the load-bearing seat 9 are fixedly connected with baffles 10. Through the baffles 10, it is convenient to limit the items and prevent them from falling.

[0023] On both outer walls of the load-bearing seat 9, second brackets 4 are fixedly connected. On both outer walls of the base 1, first brackets 2 are fixedly connected. Telescopic rods 3 are arranged between the first brackets 2 and the second brackets 4, and the telescopic rods 3 are fixedly connected to the first brackets 2 and the second brackets 4. The second brackets 4 facilitate the limitation of the load-bearing seat 9, avoiding the left and right movement of the load-bearing seat 9 under the action of the first lifting rod 5 and the second lifting rod 6, and enabling it to only move up and down.

[0024] On the outer wall of the support frame 13, a servo motor 12 is fixedly connected, and the output shaft of the servo motor 12 is fixedly connected to the sprocket disc 14. By starting the servo motor 12 through an external power supply, the output shaft of the servo motor 12 completes the driving of the support frame 13.

[0025] The implementation principle of a warehousing and logistics lifting and conveying device according to an embodiment of the present application is as follows: Place the device at the position where handling or discharging is required, and make the conveying directions of the two conveyor belts 11 correspond to the discharge port or the feed port. First, when the device needs to rise, place the items on the two conveyor belts 11 on the load-bearing seat 9. The worker only needs to rotate the bidirectional lead screw 8, so that the bidirectional lead screw 8 drives the driving blocks 7 on both sides to move towards each other, shortening the distance between the two driving blocks 7. Through the articulated connection of the first lifting rod 5 and the second lifting rod 6, the first lifting rod 5 and the second lifting rod 6 drive the load-bearing seat 9 to rise through the connecting frame 17, and then raise the items on the load-bearing seat 9 to an appropriate position. Then, start the servo motor 12 by turning on the external power switch, so that the output shaft of the servo motor 12 drives the sprocket disc 14 to rotate, so that the sprocket disc 14 drives another sprocket disc 14 to rotate synchronously through the chain 15, and then completes the driving of the transmission shaft 16. The transmission shaft 16 can drive the driving wheels located on the conveyor belt 11 to rotate synchronously, and then the driving wheels drive the conveyor belt 11 adapted to them to rotate and convey, so that the items are conveyed to an appropriate position. Secondly, when the device needs to descend, the bidirectional lead screw 8 can be rotated in the reverse direction, so that the bidirectional lead screw 8 drives the driving blocks 7 on both sides to move in the opposite direction, increasing the distance between the two driving blocks 7, and then the first lifting rod 5 and the second lifting rod 6 contract, causing the items on the load-bearing seat 9 to descend.

[0026] The above text describes an exemplary implementation manner of a warehousing and logistics lifting and conveying device provided by the present disclosure with reference to preferred embodiments. However, those skilled in the art can understand that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above specific embodiments, and various combinations of the technical features and structures proposed by the present disclosure can be made, without exceeding the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
