Background

After a powdery material storage is used for a certain period of time, the phenomenon that the powdery material storage is full and empty once being put occurs, namely the effective storage of the storage is greatly reduced. In this case, in order to make the powdery material storage capable of being used normally, it is necessary to perform a storage cleaning operation for cleaning the material remaining in the storage and restoring the storage function of the storage. The existing cement silo cleaning equipment mainly comprises a lifting mechanism, a rotating mechanism and a silo cleaning mechanism, wherein the lifting mechanism and the silo cleaning mechanism are commonly in flexible connection, support in a silo is lacked, and cleaning efficiency is low.

The design of the supporting platform in the warehouse can overcome the defect of flexible connection, and a stable fulcrum is provided for the warehouse cleaning machine. However, due to the requirement of sealing and waterproofing the top of the cement silo, the opening of the top is strictly limited, i.e. the smaller the opening, the better. For example, chinese patent with the patent name of in-warehouse supported work platform warehouse cleaning mechanism, which is published under the publication of CN205312698U, discloses an in-warehouse supported work platform warehouse cleaning mechanism, wherein a supporting mechanism of the in-warehouse supported work platform warehouse cleaning mechanism uses a supporting arm as a supporting platform, but the supporting mechanism does not consider the problem of the size of a top opening, and cannot enter the warehouse in a limited aperture, thereby being extended to a working state. The support mechanism neglects the limitation of various factors under the actual working condition and has high implementation difficulty.
