Description

An inspection shoe for easy balance

technical field

The invention relates to the technical field of auxiliary equipment for inspection equipment, in particular to an inspection shoe that is convenient for balance.

Background technique

According to the general requirements for on-site conditions in the safety technical specification for special equipment "Stationary Pressure Vessel Safety Technology Supervision Regulations", the user unit and related auxiliary units should do a good job of technical treatment after shutdown and safety inspection before inspection as required. Do relevant preparations.

When inspecting the inner surface of some super-large-volume pressure vessels and atmospheric pressure vessels, inspectors need to crawl on the wall for macroscopic inspection, thickness measurement and non-destructive testing. Often the walls of the container are curved, with a gentle slope that can be crawled on. The existing method is to set up climbing facilities such as scaffolding and portable ladders for inspection. For adopting this method, on the one hand, it is time-consuming and laborious; Scaffolding and portable ladders are not easy to support and erect. In addition, for super-large containers, wearing inspection shoes and directly crawling on the wall of the equipment while wearing a seat belt will make the inspection more convenient and efficient. We noticed that when the daily inspection shoes are used on a sloped equipment wall, since the heel and toe are not on the same level, it is difficult for the inspector to control the balance to carry out the inspection. The inspectors bring greater inspection difficulty, and the existing inspection shoes do not have the ability to self-adaptively adjust the inclination to improve the balance of the human body. In view of this, it is necessary to improve the existing inspection shoes.
