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.

Please refer to Figures 1-4. An embodiment of the utility model provides: a crane that can be stably carried, including a main beam 5, a rope guide 4 is slidably sleeved on the top of the main beam 5, a supporting device 3 is fixedly installed on the bottom end of the rope guide 4, an alignment device 2 is symmetrically slidably installed inside the supporting device 3, a positioning device 1 is fixedly installed at the top center of the supporting device 3, the positioning device 1 includes a synchronization rod 6, a hydraulic cylinder 7 and an alignment rod 8, the synchronization rod 6 is fixedly installed at the top center of the hydraulic cylinder 7, the alignment rod 8 is fixedly installed at the bottom two ends of the synchronization rod 6, the alignment device 2 includes a slide bar 9 and a rack 10, and the slide bar 9 is fixedly installed at the outer center of the rack 10.

The supporting device 3 includes a driving motor 11, a vertical rod 12, a supporting base 13, a hook 14, a gear 15 and a side plate 16. The vertical rod 12 is symmetrically fixedly mounted on the top of the supporting base 13, the driving motor 11 is fixedly mounted on the inner top of the supporting base 13, the gear 15 is fixedly mounted at the bottom center of the driving motor 11, the hook 14 is fixedly mounted on the bottom center of the supporting base 13, and the side plates 16 are fixedly mounted on both sides of the supporting base 13. The side plates 16 are installed on the bottom end of the supporting base 13 through the hook 14, so that the hook 14 can be supported to lift external objects.

The slide bar 9 is slidably inserted on the inner side of the side plate 16 away from the gear 15. The gear 15 is meshed with the rack 10. When the gear 15 rotates, the rack 10 can be driven to move.

The hydraulic cylinder 7 is fixedly mounted at the top center of the support base 13, and the synchronization rod 6 is slidably sleeved on the vertical rod 12, which can ensure that the alignment rod 8 moves up and down along a straight line.

Round holes matching the alignment rods 8 are equidistantly provided on the top of the rack 10 , so that the alignment rods 8 can be easily inserted into the top of the rack 10 .

A through hole is provided on the top end of the side plate 16 to allow the alignment rod 8 to pass through the side plate 16 and connect with the rack 10 .

Working principle: When in use, first place the external materials that need to be hoisted on the hook 14, then the hydraulic cylinder 7 can be started to drive the alignment rod 8 to move out of the circular hole inside the top of the rack 10, and then the drive motor 11 can be started to drive the gear 15 to rotate, and the rack 10 is meshed with the gear 15, so that when the gear 15 rotates, it can drive the rack 10 to move. At the same time, a positioning baffle is installed at the end of the rack 10 away from the gear 15, so that when the rack 10 moves inwardly, it can drive the positioning baffle to contact with the external materials, thereby self-centering the external materials.
