Description of the Drawings

[0016] Figure 1 is a schematic structural diagram of the present utility model. Detailed Embodiments

[0017] The following is combined with Figure 1 and further illustrates the technical solution of the present utility model through specific embodiments.

[0018] As Figure 1 shown in the mobile rapid roll changing device for replacing the roller 18 on the roll-equipped device 17, including: a trolley 1, an electric trolley 7, a cross beam 5, a lifting drive mechanism, a first upright post 2, a hanging rod 11 and a hook plate. The trolley 1 and the first upright post 2 are distributed on both sides of the roll-equipped device 17. In this embodiment, rollers 9 are respectively arranged at the bottoms of the trolley 1 and the first upright post 2, and the movement is flexible. It can be assembled near the roll-equipped device 17, occupies a small space, and has good adaptability to obstacles above the roll-equipped device 17.

[0019] A second upright post 3 extending upward is arranged on one side of the trolley 1 away from the roll-equipped device 17. The cross beam 5 is horizontally arranged on the first upright post 2 and the second upright post 3. In this embodiment, first through holes corresponding to the first upright post 2 and the second upright post 3 are arranged on the cross beam 5, and first nuts 6 located below the cross beam 5 are arranged on the first upright post 2 and the second upright post 3, which is convenient for adjusting the height of the cross beam 5 and has good adaptability to the height of the roll-equipped device 17.

[0020] A first guide rail 15 is longitudinally arranged on the trolley 1, and a roller positioning seat 16 is arranged on the first guide rail 15. In this embodiment, V-shaped grooves are arranged on the roller positioning seat 16 at intervals along the length direction of the first guide rail 15, and several old rollers and new rollers can be horizontally placed.

[0021] As Figure 1 shown, the electric trolley 7 is arranged on the cross beam 5. As Figure 1 shown, a second guide rail 4 located below the electric trolley 7 is transversely arranged on the cross beam 5 to guide the movement of the electric trolley 7 and avoid deflection.

[0022] The lifting drive mechanism 8 is arranged on the electric trolley 7 and moves with the electric trolley 7. The hanging rod 11 is horizontally arranged below the cross beam 5 and connected to the lifting drive mechanism 8. In this embodiment, the lifting drive mechanism 8 adopts an electric hoist, which has a simple structure and can perform forward and reverse operations through a configured controller to realize the lifting of the hanging rod 11.

[0023] The hook plates 13 are symmetrically arranged on the hanging rod 11 and extend downward. A supporting block 14 corresponding to the end of the roller 18 is arranged on the inner side of the bottom of the hook plate 13. In this embodiment, a clamping groove is concavely arranged at the top of the supporting block 14, and the two ends of the roller 18 can be clamped and lifted by using the clamping groove. The supporting block 14 and the roller 18 are lifted through the lifting drive mechanism 8 and the hanging rod 11, and then the electric trolley 7 is used for transverse movement, so as to realize the transfer of the roller between the roller positioning seat 16 and the roller-equipped device 17, and the roller 18 can be quickly replaced, improving the convenience of maintaining the roller-equipped device.
