    The anti falling object platform of the low-pressure cylinder of the steam turbine is designed according to the internal structure of different low-pressure cylinders. The main material of the low-pressure cylinder anti falling object platform is multi-layer Kevlar cloth, and the auxiliary materials are high-strength synthetic fiber ropes with rope sleeves at both ends. The metal hanging parts are made of 304 stainless steel and galvanized parts.    At present, the low-pressure cylinder anti falling object platform designed by our company is fixed inside the low-pressure cylinder by binding. 5-6 people can work in one low-pressure cylinder, and the installation time is completed within 4 hours. The design of the anti falling object platform for the low-pressure cylinder of the steam turbine is lightweight, easy to install, fire-resistant, anti smashing, and has no risk of falling. It can effectively handle falling objects above the cylinder and protect the cooling titanium pipes inside the low-pressure cylinder. Avoiding the risk of falling from traditional scaffolding and steel grating installation inside low-pressure cylinders. Compared to the traditional method of installing anti falling objects on low-pressure cylinders, it has improved work efficiency. The anti falling object platform of the low-pressure cylinder of the steam turbine can be reused multiple times, and it is convenient to store after use. At present, our company's low-pressure cylinder anti falling object platform for steam turbines is used in Yangjiang Nuclear Power Plant, Lingdong Nuclear Power Plant, and Fangchenggang Nuclear Power Plant.

The pressure type bolt elongation measuring ruler (hereinafter referred to as the measuring ruler) is a specialized measuring tool used to compare and measure the length of steam turbine cylinder bolts before and after hot tightening.The characteristic of our company's research and development of a pressure type bolt measuring ruler is that when measuring the length of the same bolt before and after hot tightening, the pressure of the measuring ruler's pressure plate is consistent with each time it hooks the bolt under the action of the pressure spring. Therefore, the comparison measurement of bolt elongation before and after hot tightening is more accurate.
