Description
Technical Field
[0001] The utility model belongs to the technical field of ship repair and processing, and in particular relates to a device for processing the inner side of a boiler manhole and a hand hole. Background Art
[0002] The ship boiler is a key energy device of the ship, responsible for providing heat energy for the ship. After the boiler has been used for a period of time, it is inevitable that the manhole and hand hole of the boiler will be damaged due to the influence of high temperature and high pressure. Checking the integrity and safety of the boiler is a common project in ship repair. Usually, a valve of the boiler is removed, the valve port is blocked with a sealing plate, the manhole and hand hole of the boiler are closed, and water is poured into the water cavity to test the tightness of the boiler tube by pressurization. In the actual pressure test process, due to the long use time of some boilers, there is corrosion on the inner wall of the manhole and hand hole of the furnace body. Poor treatment will cause poor sealing performance during the pressure test and leakage. The traditional method is to grind the corroded inner side of the manhole and hand hole, place high-pressure gaskets on the manhole and hand hole, and apply iron cement to ensure the smoothness of the inner side of the manhole and hand hole, so that the manhole and hand hole are well sealed after the manhole cover and hand hole cover are covered. However, ferrocement is not resistant to high temperatures. The high-temperature combustion in the boiler causes the inner wall to not fit tightly and leak, which requires repeated disassembly and assembly of the manhole and handhole, seriously affecting the efficiency of the pressure test operation.
[0003] If the furnace manhole and handhole are repaired by arc welding for small corrosion pits and welding for large areas of deep corrosion, grinding is required, but conventional boring machine equipment cannot be processed on site. In view of this situation, a tool is urgently needed to bore the inner side of the boiler manhole to ensure the sealing of the furnace manhole and handhole. Utility Model Content

During the processing, the processing angle can be adjusted by an adjustable support structure to optimize the processing so that the accuracy after processing meets the requirements.
[0044] By studying and analyzing the leakage mechanism of boiler manholes and handholes, a device for processing the inside of boiler manholes and handholes corresponding to boiler manholes and handholes on site was developed, solving the technical problems of boiler manhole and handhole tightness and furnace tube pressure test.
