Description

Technical Field

[0001] The utility model relates to the technical field of suspension devices, in particular to a suspension device for a large cement machine. Background Art

[0002] Cement machinery refers to various production, mixing and molding machines used in the production of cement. In the process of producing the mixing drum in the mixer of cement machinery, a suspension device is needed to lift it up for painting.

[0003] In the prior art, there is a suspension device for a large cement machinery with publication number CN213377396U, which includes a suspension frame and a fixing mechanism, wherein a bottom frame is integrally formed at the inner bottom of the suspension frame, two groups of connecting frames are nested on the inner side of the bottom frame, and a ventilation fan is installed on the inner side of the connecting frame; the fixing mechanism includes a connecting plate and a fixing plate, and the outer walls on both sides of the suspension frame are integrally formed with connecting plates, and the left and right sides of the top plate of the connecting plate are supported by fixing plates, a socket is provided at the top center of the fixing plate, a suspension rod is screwed into the socket, the suspension rod and the connecting plate are provided with first fixing holes corresponding to the positions, first fixing bolts are screwed into the two groups of the first connecting holes, and second fixing holes corresponding to the positions are provided on both sides of the fixing plate and the connecting plate.

[0004] The above patent technology proposes a suspension device for large cement machinery, which has the advantages of faster curing speed of the suspended large cement machinery and no loosening of the connection between the suspension rod and the connecting plate. However, in the actual process of hanging and painting the mixing drum, it is impossible to effectively position the mixing drums of different diameters, resulting in poor stability of the mixing drum after hanging.
