Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of braking machinery, and particularly relates to a manual emergency release device for an electric hydraulic block-type brake. BACKGROUND

[0002] At present, the electric hydraulic block-type brake used in the gate opening and closing equipment of domestic hydraulic engineering is always in a braking state when there is no power driving due to its working principle. In some special cases, the electric hydraulic block-type brake is always in a locked state, which is not conducive to operation when there is no power. The emergency solution is to use auxiliary tools to manually pry the lever part of the electric hydraulic block-type brake, and the lever movement releases the brake, thereby achieving the purpose of unlocking the brake. The above method has certain defects: the randomness of the manual prying position may cause damage to the equipment body, and the safety risk of personnel operation is large. Therefore, the opening and closing equipment needs to consider adding the opening and closing operation condition under no power driving when designing. SUMMARY
