Ground rails 2 are arranged on both sides of the bottom of the frame body 1. A longitudinal moving part 3 is arranged between the top of the ground rail 2 and the bottom end of the frame body 1. Reinforcing plates 5 in the shape of a trapezoid are arranged between the bottoms of both sides at the two ends of the frame body 1 and the two ends at the top of the longitudinal moving part 3. When the longitudinal moving part 3 moves on the ground rail 2, it can drive the crane to move longitudinally. A transverse moving guide rail 6 is arranged at the top end of the frame body 1. A reserved groove 7 is arranged at the middle position of the inner top end of the frame body 1. A transverse moving part 8 is arranged at the top end of the frame body 1. A connecting vertical plate 9 is arranged at the middle position of the bottom end of the transverse moving part 8. An electric hoist main body 10 is arranged at the top end inside the frame body 1. The bottom end of the connecting vertical plate 9 passes through the reserved groove 7 and is fixedly connected to the top end of the electric hoist main body 10. When the transverse moving part 8 moves on the transverse moving guide rail 6, it can drive the electric hoist main body 10 to move horizontally on the frame body 1. A suspension cable 15 is arranged outside the electric hoist main body 10. A hook 11 is arranged at the bottom end of the suspension cable 15. An item is hung by the hook 11, and the suspension cable 15 is driven to be wound and unwound by the electric hoist main body 10 to perform the hoisting and lowering operation of the item.

[0022] As a further implementation manner of this embodiment, as Figure 1 and Figure 2 shown, cleaning push plates 4 are arranged at the bottoms of both ends of the longitudinal moving part 3. The bottom end of the cleaning push plate 4 is in the shape of a "mountain", and the bottom end of the cleaning push plate 4 fits with the top end of the ground rail 2. When the longitudinal moving part 3 moves on the ground rail 2, it drives the cleaning push plate 4 to move on the ground rail 2 to push away and clean the garbage that has fallen inside and outside the ground rail 2. Thus, it is avoided that there are objects on the ground rail 2, which may cause the longitudinal moving part 3 to derail when moving, affecting the stability of the crane when hoisting items, making the crane operate more safely, and there is no need to manually clean the garbage on the ground rail 2.

[0023] As a further implementation manner of this embodiment, as Figure 1-4 shown, a disassembly and assembly component is arranged between the bottom end of the suspension cable 15 and the top end of the hook 11. The disassembly and assembly component includes an installation sleeve 12. The installation sleeve 12 is arranged at the bottom end of the suspension cable 15. An installation seat 14 is arranged at the top end of the hook 11. A positioning through hole 16 is arranged inside the installation sleeve 12, and the positioning through holes 16 are arranged at equal intervals inside the installation sleeve 12. A fastening screw hole 17 is arranged outside the installation seat 14, and the fastening screw holes 17 are arranged at equal intervals outside the installation seat 14. A fastening bolt 13 passes through the inside of the positioning through hole 16, and one end of the fastening bolt 13 is inserted into the inside of the fastening screw hole 17. In this way, the purpose of firmly connecting the installation seat 14 inside the installation sleeve 12 can be achieved, thereby fixedly connecting the hook 11 to the suspension cable 15. By loosening and removing the fastening bolt 13, the hook 11 can be disassembled and replaced, thus achieving the effect of being able to replace and select a suitable hook 11 according to the types of hoisted items, making the application range of the crane wider.

[0024] When in use, the mounting seat 14 is clamped inside the mounting sleeve 12, and the fastening screw holes 17 are aligned with the positioning through holes 16 one by one, and then the fastening bolts 13 are inserted into the positioning through holes 16 and inserted into the fastening screw holes 17 and tightened, so that the mounting seat 14 is firmly connected to the inner side of the mounting sleeve 12, so that the hook 11 and the suspension cable 15 are fixedly connected, and the fastening bolts 13 can be loosened and removed to disassemble and replace the hooks 11 for different purposes to perform lifting and hanging operations on different types of objects;

[0025] Specific working principle:

[0026] When using the electric hoist bridge crane, firstly, the mounting seat 14 is clamped inside the mounting sleeve 12, and the fastening screw hole 17 is aligned with the positioning through hole 16 one by one, and then the fastening bolt 13 is passed through the positioning through hole 16 and inserted into the inside of the fastening screw hole 17 and tightened, so that the mounting seat 14 is firmly connected to the inner side of the mounting sleeve 12, so that the hook 11 and the lifting cable 15 are fixedly connected, and then the lifting cable 15 and the hook 11 are lowered through the electric hoist body 10, and the objects are hung through the hook 11, and then the objects are lifted by the electric hoist body 10, and at the same time, the longitudinal moving part 3 can drive the crane to move longitudinally by moving on the ground rail 2, and the transverse moving part 8 can drive the electric hoist body 10 to move transversely on the frame 1 to adjust the hanging position, and the longitudinal moving part 3 drives the cleaning push plate 4 to move on the ground rail 2 when moving, and pushes away and cleans the garbage falling inside and outside the ground rail 2, so as to avoid objects on the ground rail 2 causing the longitudinal moving part 3 to derail when moving and cause a safety accident.
