The logistics robot lifting mechanism, through the arrangement of the electric telescopic rod, the flange, the fixed plate, the arc block, the hook, the hanging ring and the placement box, starts the electric telescopic rod so that its output end drives the placement box to move, which can not only lift the goods in the placement box, but also enhance the stability of the goods during lifting through the coordinated use of multiple steel cables. Through the arrangement of the placement box, the first motor, the threaded rod, the threaded barrel, the support plate, the second motor and the transmission roller, the first motor is started to drive the threaded rod to rotate, so that the threaded barrel drives the goods on the support plate to move outward, so that the device can be docked with the logistics conveying platform, which is convenient for the placement of goods and improves the practicality of the device.

[0004] In the prior art, it is not possible to ensure the stability of the device during the lifting process, and no auxiliary structure for balancing the device is provided, so a logistics robot lifting mechanism is now needed. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides: a logistics robot lifting mechanism, such as Figure 1-Figure 5As shown, it includes a limiting mechanism 1 and a lifting mechanism 6; the limiting mechanism 1 includes two groups of symmetrically installed C-shaped aluminum profile columns 2, and the corresponding sides of the two groups of C-shaped aluminum profile columns 2 are provided with slide grooves 3 and limiting grooves 4, and a synchronous belt 5 is installed inside the limiting groove 4; the lifting mechanism 6 includes a connecting frame 7, and mounting plates 9 are installed on both sides of the connecting frame 7, and two groups of main rollers 11 and measuring guide wheels 12 are rotatably installed on the outer side of each group of mounting plates 9, and a group of synchronous belt tensioning structure 14 is installed on the outer side of each group of mounting plates 9; the synchronous belt tensioning structure 14 includes a positioning frame 15 bolted to the outer side of the mounting plate 9, and a sliding block 17 is elastically installed inside the positioning frame 15, and a second limiting clamping plate 21 is bolted to the outer side of the sliding block 17; each group of main rollers 11 and measuring guide wheels 12 are rotatably installed in contact with the inner wall of the slide groove 3, and the second limiting clamping plate 21 extends into the limiting groove 4 and is installed in cooperation with the synchronous belt 5.

[0029] Preferably, a group of force-bearing plates 8 are bolted to both ends of the connecting frame 7, and a mounting plate 9 is bolted to the outside of each group of force-bearing plates 8. The force-bearing plates 8 installed at both ends of the connecting frame 7 can improve the use strength of the mounting plate 9, so that the components on the outside of the mounting plate 9 can be used more stably.

[0030] Furthermore, two groups of mounting seats 10 are symmetrically bolted on the upper and lower outer sides of each group of mounting plates 9, and a group of main rollers 11 and measuring guide wheels 12 are respectively installed on the outer sides of each group of main rollers 11. The mounting seats 10 installed on the outer sides of the mounting plates 9 limit the main rollers 11 and the measuring guide wheels 12 to ensure the rotation of the main rollers 11 and the measuring guide wheels 12. The main rollers 11 and the measuring guide wheels 12 have different rotation angles. The measuring guide wheels 12 rotate against the two sides of the slide groove 3, and the measuring guide wheels 12 rotate against the inner side of the slide groove 3 to ensure that the device can move more stably.

[0031] Furthermore, a group of first limit clamps 13 are bolted and installed on the outer side of each group of mounting plates 9, and the synchronous belt 5 extends from the inside of the first limit clamps 13. The first limit clamps 13 installed on the outer side of the mounting plate 9 are used in conjunction with the synchronous belt 5. The coordination of the synchronous belt 5, the first limit clamps 13 and the second limit clamps 21 ensures the overall stable lifting of the lifting mechanism 6, and the synchronous belt tensioning structure 14 can adjust the unilateral use position of the lifting mechanism 6 to ensure synchronization of the two sides of the lifting mechanism 6.

[0032] It is worth mentioning that two groups of limit bolts 16 are symmetrically installed inside the positioning frame 15, and the sliding blocks 17 are slidably installed outside the two groups of limit bolts 16. The positioning frame 15 limits the limit bolts 16, and the sliding blocks 17 slidably installed outside the limit bolts 16 can control the movement of the second limit clamp 21 to pull the single-sided synchronous belt 5 to the side, thereby realizing the synchronization of the two sides of the lifting mechanism 6.

[0033] Specifically, a group of buffer springs 18 are installed on the outside of each group of limit bolts 16. The buffer springs 18 are located at the lower part of the sliding block 17, and the two ends of the buffer springs 18 are respectively fixed to the sliding block 17 and the surface of the positioning frame 15. The installed buffer springs 18 can buffer the sliding block 17, and pull the sliding block 17 to the side when the lifting mechanism 6 tilts on one side. The limit bolts 16 pull the sliding block 17 to the side or push the sliding block 17 to ensure the reset of the second limit clamp 21.

[0034] In addition, two groups of movable rods 19 are installed through the upper part of the positioning frame 15. The bottom end of each group of movable rods 19 is fixedly installed with the sliding block 17. The two groups of movable rods 19 further limit the movement of the sliding block 17 to prevent the sliding block 17 from tilting and getting stuck.

[0035] Preferably, a connecting plate 20 is bolted to the outer side of the sliding block 17, and a second limiting clamp 21 is fixedly installed on the outer end of the connecting plate 20. The synchronous belt 5 extends from the inside of the second limiting clamp 21, and the inner sides of the first limiting clamp 13 and the second limiting clamp 21 are provided with tooth grooves 22. The connecting plate 20 limits the second limiting clamp 21, and the tooth grooves 22 opened inside the second limiting clamp 21 and the first limiting clamp 13 are meshed with the synchronous belt 5 to ensure the overall movement of the lifting mechanism 6.

[0036] Furthermore, a limiting frame 23 is fixedly installed on the outer side of the connecting frame 7, and a placement plate 24 is bolted and installed on the upper side of the limiting frame 23. The limiting frame 23 and the placement plate 24 installed on the outer side of the connecting frame 7 ensure the mobility of the objects.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
