Description
Technical field [0001] The invention relates to a shut-off door ratchet backstop system, which can be widely used in a boiler slag conveying system. Background technique [0002] The hydraulic shut-off door is hoisted under the slag shaft at the bottom of the boiler. It is an important equipment to ensure the furnace pressure during boiler maintenance and operation and to ensure the personal safety of maintenance personnel. However, due to long-term operation under severe working conditions, due to many reasons such as structural deformation, the equipment is prone to failure, and there are great hidden dangers to the personal safety of maintenance personnel. Summary of the invention [0003] The object of the present invention is to provide a shut-off door ratchet backstop system that is reliable in structure, realizes backstop, and supports the shut-off door leaf. [0004] In order to achieve the above objective, the shut-off door ratchet check system of the present invention inc...
