Description

Technical Field

[0001] The utility model relates to the technical field of boiler pipelines, in particular to a high-temperature and high-pressure thermal power plant boiler pipeline connection structure. Background Art

[0002] A thermal power plant, referred to as a thermal power plant, is a plant that uses combustibles (such as coal) as fuel to produce electricity. Its basic production process is: when the fuel is burned, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. Then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy. An existing patent for a thermal power boiler pipeline connection structure, patent publication number CN219665511U, includes a base, a first slide bar is fixed on the top wall of the base, a first threaded shaft is rotatably connected to the top wall of the base in front of the first slide bar, and a first threaded shaft is rotatably connected to the top wall of the base in front of the first slide bar. A slide rod is slidably connected to a placement plate; the utility model places the boiler pipe on the placement plate and fixes the connecting pipe through four arc plates, controls the rotation of the gear through a servo motor, and drives the slider to move circumferentially around the inner diameter of the welding ring through the engagement of the gear and the annular rack, drives the second telescopic rod to be telescoped or extended through the second cylinder, drives the electric-controlled welding gun to weld to the connection between the boiler pipe and the connecting pipe through the second telescopic rod, and drives the electric-controlled welding gun to move circumferentially through the circumferential movement of the slider, thereby performing dead-angle welding on the connection between the boiler pipe and the connecting pipe.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, when the boiler pipe is in use, it is necessary to connect it. At that time, due to its high temperature, it is not convenient to position and connect the two pipes during use, which affects the normal use of the subsequent connection structure. Therefore, we propose a high-temperature and high-pressure thermal power plant boiler pipe connection structure to solve the above-mentioned problems. Utility Model Content
