Description

Technical Field

[0001] The present invention relates to the technical field of handling devices, and particularly relates to a handling device for barreled magnetorheological fluid. Background Art

[0002] Magnetorheological fluid is a suspension containing magnetic particles, and its rheological properties will change significantly under the action of an external magnetic field. Its rheological properties can be rapidly changed under the action of an external magnetic field. This characteristic enables magnetorheological fluid to have a wide range of applications in many fields. During the production and transportation process of magnetorheological fluid, it is mostly loaded and transported in a barreled manner. To facilitate the transfer of magnetorheological fluid, it is necessary to handle the barreled magnetorheological fluid during the transportation and transfer process. For the convenience of its use, a handling device is required.

[0003] As for the current traditional barreled handling device, it mainly moves and handles the loading barrel by means of a handling vehicle. However, since the magnetorheological fluid is contained in the loading barrel, the overall volume of the barrel is relatively heavy. The traditional handling method mainly uses a forklift for handling. During the alignment process, the forklift is prone to deviation, so it is easy to collide with the barrel during alignment, which is likely to damage the barrel and make it inconvenient to use.

[0026] Specific usage method and function of this embodiment: In the present invention, during the assembly process, by pushing the telescopic clamp 204, the telescopic clamp 204 contracts in the inner extension groove 203 under the action of an external force, and then the connecting block 201 is sleeved on the side facing block 104, so that the connecting block 201 is docked with the middle fixing frame 101. Then, the restraint on the telescopic clamp 204 is released, and the telescopic clamp 204 is elastically reset under the action of the spring, so as to penetrate through the side facing block 104 and then connect the middle fixing frame 101 and the connecting block 201 with screws to maintain the stability of their connection.

Then, through direction operation, independent unloading is performed after the handling of the barreled magnetorheological fluid is completed. At the same time, by continuously controlling the downward movement of the lifting support plate 303, the locking bracket 304 is disengaged from the bottom fixing frame 302 to release the restraint on the loading and unloading cart 301.
