Temporary lifting guide system for installation inside combined heat and power plant boilers

Boiler Internal Lifting Guide System with Enhanced Safety via Rack-and-Pinion Gear Engagement and Guide Groove Structure

This technology is a temporary lifting guide system for combined heat and power (CHP) plant boilers. It consists of temporary support members that install multi-level scaffolding at a set distance from the boiler furnace wall, a lifting guide member equipped with rack gears and guide grooves, and a temporary lifting unit that moves along this guide to allow for inspection and maintenance of the furnace wall.

Conventional inspection and maintenance work inside CHP plant boiler furnaces often lacks dedicated temporary lifting equipment, forcing workers to perform high-altitude tasks in unstable positions and posing a high risk of safety accidents.

This technology uses a pinion gear driven by a motor that engages with the rack gear on the lifting guide member to move the lifting platform up and down. Guide rollers are fitted into guide grooves on both sides to prevent detachment, allowing workers to safely ascend, descend, and perform maintenance tasks within the boiler furnace.

Key Features:

• Temporary support members that hold multi-level scaffolding at a set distance from the boiler furnace wall
• A lifting guide member fixed to the temporary support members, featuring a rack gear along one side of the vertical column and guide grooves along both sides
• A temporary lifting unit consisting of a plate-type lifting platform, a pinion gear installed on the platform that engages with the rack gear of the lifting guide member, and a drive motor to rotate the pinion gear
• Guide rollers installed on the lifting platform that fit into the guide grooves on both sides of the lifting guide member to direct the platform's movement and prevent it from detaching
