Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a suspension crane. Background Art

[0002] A suspension crane is a common lifting equipment. It has a hook suspended on a lifting beam and can move horizontally along the track of the beam, as well as be lifted and lowered vertically through a lifting mechanism. This type of crane is usually used in factories, warehouses, docks and other places to carry out cargo handling and lifting operations. Publication No. CN208617247U discloses a suspension crane. By providing a reinforcing rod between the support and the beam, the bearing capacity of the beam is higher, thereby making the crane more widely used. By arranging the reinforcing rod on the surface of the driven platform, the reinforcing rod rotates with the beam when the beam rotates, thereby ensuring the service life of the reinforcing rod. However, the shaking phenomenon that is difficult to avoid when the suspension crane is lifting cargo may cause the cargo to become unstable or sway, increasing the risk of the cargo falling off or tilting, which may affect the safety and efficiency of the operation. At the same time, the shaking may cause the relative position between the hook and the cargo to change during the lifting process, reducing the accuracy and precision of the operation, which may cause the cargo to fail to be accurately placed or docked. Therefore, it needs to be improved. Utility Model Content

[0026] Embodiment 2

[0027] See also Figure 1 , 2 A fixing box 19 is fixedly installed on one side of the pillar 2, and a partition plate 20 is fixedly installed inside the fixing box 19. The fixing box 19 is convenient for placing notebooks and markers, so that the staff can record the lifting height, weight and other data in real time.

[0028] Working principle: When the staff operates the suspension crane, they use the hook hanging under the jack 4 to lift the goods, and start the motor 6 in the jack 4 to make the hook rise vertically. Then the staff starts the motor 6, and then the motor 6 drives the threaded rod 7 to rotate, so that the lifting plate 10 can be lifted up under the joint action of the threaded rod 7 and the slide bar 9. As the goods rise vertically, the pull rope 15 moves upward until the lifting plate 10 rises to the bottom of the goods, thereby supporting the vertically rising goods lifted by the jack 4. At this time, the vertical lifting of the goods is stopped. During the lifting operation, the goods are moved in the horizontal direction of the crossbeam 3 through the lifter 4, and then the goods are moved between the two sets of anti-sway baffles 12, so as to prevent the goods from shaking during the lateral shifting process, avoid the goods from falling off or tilting due to instability or swaying, and improve the safety of the operation until the goods move to the top of the groove 13. Similarly, the goods are vertically lowered through the lifter 4 until the goods move to the specified position. At the same time, the anti-sway baffle 12 is also used to prevent the relative position between the hook and the goods from changing, thereby improving the accuracy and precision of the operation.
