Description

The present invention deals with the technical field of removing the blockade lid in hydraulic work, and particularly relates to the blockade lid removing device for hydraulic work.

In irrigation works, Y-shaped pipelines are often used in areas where sediments are likely to accumulate due to pipeline communication. Further, by closing one opening of the pipeline with a blocking lid, if the lid is removed for maintenance or the like, it is convenient to remove foreign matter inside the pipeline, and communication can be performed more easily. However, the sealing lids currently used are basically screwed together and are wrapped with sealing tape due to their sealing property, which is very complicated when removed. In addition, the work of removing the lid is basically time-consuming and laborious as a whole, because the worker often manually twists and removes the lid using the removing device. Furthermore, the existing removal device requires the operator to manually fix it to the lid, and it is difficult to adjust the holding force against the lid. Therefore, if the force is too strong, the lid will be deformed and difficult to remove. If it is too weak, it will be slippery and difficult to remove. The present invention can solve the above problems.
