[0027] Example

[0028] In order to solve the problem that the hoisting equipment used for hoisting paper roll A in the prior art cannot clamp the paper roll quickly when in use, and cannot prevent it from falling off, which may easily cause property losses and personnel losses, reference is made to Figure 1 and Figure 2 As shown, the present application discloses an anti-drop lifting device, comprising:

[0029] Mobile platform 10;

[0030] A robot 20, the robot 20 is connected to the mobile platform 10 and is driven to move by the mobile platform 10;

[0031] The lifting and fixing mechanism 30 includes a door frame 31, a lifting drive assembly 32 and a coil clamp 33. The door frame 31 is installed on the execution end 21 of the robot 20. The lifting drive assembly 32 is arranged above the inside of the door frame 31. The coil clamp 33 is connected to the lifting drive assembly 32 and driven to lift.

[0032] The anti-slip mechanism 40 includes a rotation drive component 43, an anti-slip base plate 41 and a telescopic blocking component 44. The anti-slip base plate 41 is hinged to the bottom of one side of the door frame 31 through a hinge shaft 42. The rotation drive component 43 is arranged on the door frame 31 corresponding to one side of the hinge shaft 42 and is connected to the hinge shaft 42. The telescopic blocking component 44 is arranged on the bottom of the other side of the door frame 31 to fix the anti-slip base plate 41 in a flat state.

[0033] During the specific implementation, the mobile platform 10 is controlled to drive the robot 20 to move to the loading position, the operator prevents the paper roll from falling, and clamps the paper roll clamp 33 after the lifting drive component 32 drives it to descend (after the paper roll is clamped, the lifting drive component 32 drives the paper roll clamp 33 to rise). After that, the rotating drive component 43 is controlled to drive the anti-slip bottom plate 41 to rotate to the bottom of the door frame 31 and be in a horizontal state. After it is in place, the telescopic blocking component 44 is actuated to fix the anti-slip bottom plate 41. Finally, the mobile platform 10 drives the robot 20 to move to realize the lifting of the paper roll.

[0034] Specifically, the mobile platform 10 of the present application includes a first servo screw-driven slide, and the base of the robot 20 is fixed on the first servo screw-driven slide. Driven by the first servo screw-driven slide, the robot 20 will move above it.

[0035] In this embodiment, a connecting column 22 is provided on the execution arm of the robot 20, and an ear seat 311 is provided at the top center of the door frame 31. The connecting column 22 is clamped inside the ear seat 311 and fixed thereto by bolts (not marked). Through this design, the door frame 31 of the present application can be quickly installed and disassembled with the robot 20. In short, it can reduce the installation intensity of the operator and improve work efficiency.

[0036] In this embodiment, the lifting drive assembly 32 of the present application includes two second servo screw-driven slides 321, and the two second servo screw-driven slides 321 are respectively vertically arranged on the inner walls on the opposite sides of the door frame 31, and a lifting plate 322 is connected between the two second servo screw-driven slides 321. When driving the coil clamp 33 to lift and lower, the two second servo screw-driven slides 321 will synchronously drive the lifting plate 322 to perform smooth lifting and lowering movements.

[0037] In this embodiment, the coil clamp 33 of the present application includes a bidirectional screw slide 331 and two clamping plates 332. The bidirectional screw slide 331 is arranged at the bottom of the lifting plate 322. The two clamping plates 332 are respectively connected to the two driving parts of the bidirectional screw slide 331, and the clamping surfaces of the two clamping plates 332 are respectively provided with plug-in protrusions 333 for inserting into the hollow part of the coil. Under the drive of the bidirectional screw slide 331, the two clamping plates 332 will move towards or away from each other. In this way, the two plug-in protrusions 333 respectively arranged on the two clamping plates 332 can be inserted into the hollow part of the paper roll or detached from the hollow part of the paper roll, thereby realizing the clamping and loosening between them.

[0038] In this embodiment, the rotation drive assembly 43 includes a servo motor 431 whose output shaft is connected to a reducer 432. The reducer 432 and the servo motor 431 are both arranged on the door frame 31 corresponding to one side of the hinge shaft 42, and the drive shaft of the reducer 432 is connected to the hinge shaft 42. Under the cooperative drive of the servo motor 431 and the reducer 432, the hinge shaft 42 will drive the anti-slip base plate 41 to rotate to the bottom of the door frame 31, so as to catch the paper roll detached from the roll clamp 33 and prevent it from directly hitting the ground, causing casualties and property losses.

[0039] In order to prevent the paper roll from falling off in the other two directions, the present application provides at least two blocking columns 411 above the front and rear sides of the anti-slip bottom plate 41, respectively. If the paper roll falls off, it will be restricted on the anti-slip bottom plate 41 and will not fall off again, thus having a higher safety factor.

[0040] In the present embodiment, the telescopic blocking assembly 44 includes a hydraulic cylinder, and a socket 412 is provided on the free side of the anti-slip base plate 41, so that the anti-slip base plate 41 is fixed when the piston rod of the hydraulic cylinder extends into the socket 412.
