Description

Technical field

[0001] The present invention relates to the field of chemical machinery, and in particular to an assembled operating platform arranged in a reaction container. [Background Technology]

[0002] A reaction vessel refers to a container used to complete physical and chemical reactions of a medium. In industrial production, especially in the chemical, pharmaceutical, fertilizer, and refining industries, reaction vessels are used in large quantities as a pressure-bearing equipment due to process needs. A reaction vessel generally includes a cylinder and internal parts arranged on the cylinder. The cylinder is provided with numerous pipe openings. The internal parts in the reaction vessel require workers to regularly inspect and maintain them. In the prior art, since there is no operating platform in the cylinder for maintenance workers to stand on, maintenance workers need to carry a ladder into the cylinder and then stand on the ladder to inspect the internal parts. When the maintenance work requires the collaboration of multiple people, multiple ladders need to be provided for multiple people to stand on. Not only is the operational safety low, but because the ladder is large, it is not easy to take the ladder in and out of the inspection port of the cylinder, which greatly reduces the maintenance efficiency.

[0003] Therefore, it is necessary to provide an assembled operating platform disposed in a reaction container to solve the above technical problems. [Summary of the invention]

[0004] In order to solve the above problems, the object of the present invention is to provide an assembled operating platform arranged in a reaction vessel with a reliable structure and convenient assembly and disassembly.

The intersection of the upper beam and the lower beam is locked by a second locking piece. The free end of the upper beam is provided with a second positioning hole, and a second positioning piece matching the second positioning hole is welded on the angle steel ring.
