Description

Technical Field

[0001] The utility model relates to the technical field of dismountable lifting tools for cranes, and specifically relates to a dismountable lifting tool for a hanging beam crane. Background Technique

[0002] A crane refers to a multi-action lifting machine that vertically lifts and horizontally transports heavy objects within a certain range. Also known as an overhead crane, a bridge crane, a hoist, the main characteristics of a tire crane are: its driving cab and lifting control cab are combined into one, and it is evolved from a crawler crane (crawler hoist). The crawler and walking support parts of the traveling mechanism are changed into a chassis with tires, overcoming the disadvantage of the crawler plate of the crawler crane (crawler hoist) damaging the road surface, and it belongs to a material handling machine.

[0003] A rotary electromagnetic hanging beam crane disclosed in the utility model patent application publication specification CN217650768U of China. Although this rotary electromagnetic hanging beam crane has the advantages of being convenient for daily maintenance and preventing swaying during work, it still has disadvantages: First, in the actual use process of this rotary electromagnetic hanging beam crane, it is often necessary to replace the lifting tool according to different lifting objects. When the entire lifting tool is replaced, it requires multiple people to cooperate in the replacement, and it takes a lot of time to replace the lifting tool, resulting in low efficiency; Second, when the lifted goods are offset in position on the crane during the actual use process of this rotary electromagnetic hanging beam crane, it will cause the center of gravity of the crane to be unstable, posing a certain safety hazard. And when the offset angle of the goods is too large, the goods may fall, and at the same time, the long-term unstable center of gravity will damage the components of the bridge crane.

The positioning block 11 is adapted to the positioning groove 12 and is clamped in the interior of the positioning groove 12. The insertion slots 13 are two and symmetrically arranged left and right and penetrate the side surface of the disassembly and assembly part 6. The threaded grooves 14 are also two and symmetrically arranged and are located inside the mounting block 10. The settings of the mounting block 10 and the installation groove 9 can initially install the disassembly and assembly part 6 and the mounting part 7. The settings of the positioning block 11 and the positioning groove 12 reposition and install the disassembly and assembly part 6 and the mounting part 7. The positioning block 11 is fixedly installed on the inner top of the installation groove 9. The positioning groove 12 is opened at the top of the mounting block 10. The insertion slot 13 is opened on the side surface of the mounting block 10. The threaded groove 14 is opened at the bottom of the insertion slot 13. A fixing mechanism is arranged on the side surface of the mounting part 7. The fixing mechanism includes a fixing rod 15, a pulling frame 16, an insertion rod 17, and a threaded column 18. The fixing rod 15 is inserted into the interior of the insertion slot 13. The pulling frame 16 is fixedly installed at the end of the fixing rod 15 and is located outside the side surface of the disassembly and assembly part 6. The insertion rod 17 is inserted into the interior of the fixing rod 15. The threaded column 18 is fixedly connected to the end of the insertion rod 17. The threaded column 18 is threadedly connected to the interior of the threaded groove 14. The other end of the insertion rod 17 horizontally penetrates the entire pulling frame 16 and is located outside. The setting of the fixing mechanism can ensure that the connection between the disassembly and assembly part 6 and the mounting part 7 is more stable.

[0025] When using this detachable sling for a hanging beam crane, when it is necessary to replace and install the sling of the hook 8 at the bottom, first insert the mounting block 10 into the interior of the installation groove 9, ensure that the positioning block 11 is clamped in the interior of the positioning groove 12 for preliminary positioning and installation, then insert the end of the insertion rod 17 with the threaded column 18 into the interior of the fixing rod 15, and rotate the insertion rod 17 so that the threaded column 18 is threadedly connected to the interior of the threaded groove 14. At this time, the fixed installation connection between the disassembly and assembly part 6 and the mounting part 7 can be completed. When it is necessary to disassemble, screw the threaded column 18 out of the interior of the threaded groove 14, and pull out the insertion rod 17 from the interior of the fixing rod 15, then pull out the fixing rod 15 from the interior of the insertion slot 13 through the pulling frame 16, and the mounting block 10 can be taken out of the interior of the installation groove 9 to complete the disassembly. It is very convenient to use and the operation is simple.
