Description

Technical Field

[0001] This utility model belongs to the field of furnace cleaning technology, specifically relating to a robot specially designed for cleaning furnaces. Background Technology

[0002] The furnace is an important component of the boiler combustion system. Its interior is subjected to high temperature, high pressure and corrosive gases for a long time, which can easily lead to problems such as ash accumulation and coking. These impurities not only reduce the boiler's thermal efficiency, but may also cause furnace blockage, increased wear, and even safety accidents. Traditional manual cleaning methods have problems such as high labor intensity, harsh working environment and many safety hazards, which make it difficult to meet the requirements of modern industrial production for high efficiency, safety and environmental protection. Utility Model Content

[0003] The purpose of this invention is to provide a robot specifically designed for cleaning the furnace, which can improve boiler operating efficiency, reduce production costs, and ensure production safety.

[0004] The specific technical solution adopted by this utility model is as follows:

A hydraulic motor is fixedly connected to the top of the second mounting plate. A rotating shaft is fixedly connected to the output end of the hydraulic motor. The bottom end of the rotating shaft passes through the mounting frame and is fixedly connected to a connecting U-shaped plate. A support bearing is rotatably connected to the outer surface of the rotating shaft. The outer ring of the support bearing passes through the bottom and inner surface of the mounting frame.

The robotic arm 11 can flexibly adjust its angle to adapt to the complex working environment inside the furnace for cleaning work. This mechanized cleaning of the furnace inner wall replaces manual cleaning, greatly improving the boiler's operating efficiency and reducing costs. To improve production costs and ensure production safety, the support bearing 6 and mounting flange 7 distribute the weight of the lower robotic arm 11 to the mounting frame 1 and the second mounting plate 3, thereby preventing the lower robotic arm 11 from placing excessive load on the hydraulic motor 4 and effectively avoiding damage to the hydraulic motor 4 due to excessive load. The first oil cylinder 15 effectively controls the extension and retraction of the moving U-shaped plate 13, allowing the moving U-shaped plate 13 to flexibly extend and retract to adapt to different sizes of furnace inner walls. The detachable support U-shaped plate 14 allows for flexible disassembly and replacement after long-term wear and tear.
