Description

Technical Field

[0001] The utility model relates to the technical field of grid wheel locking, and more specifically, to a mechanical locking device for a large grid wheel. Background Art

[0002] The working principle of a large grid wheel is based on the dynamic principles of centrifugal jet and thrust runner. Ash slag enters the bins of the grid wheel through the inlet pipe, and then is centrifugally thrown out by the drum blades on the bins. After being pushed by the thrust runner, it is finally discharged to the downstream equipment. During the whole process, the grid wheel feeder will form a sealed cavity. When the rotor rotates, the grid blades will scrape the material out of the bin and form a certain pressure in the cavity, so as to realize continuous and uniform material transportation.

[0003] When it is necessary to clean the inside of the grid wheel, it is necessary for the staff to enter the inside of the grid wheel for cleaning. However, when people enter the inside of the device, the grid wheel will rotate. Therefore, it is necessary to brake the grid wheel to prevent it from rotating. The current method is generally to cut off the power of the grid wheel and insert a crowbar into the gap between the grid wheel and the housing, and use the crowbar to cause extrusion between the grid wheel blades and the housing to lock the grid wheel. However, the crowbar is easily displaced due to external force. Once the locking fails, it is easy to cause personal injury to the internal staff. Therefore, it is necessary to transform and optimize it. Summary of the Utility Model
