Description

Technical Field

[0001] This utility model relates to the field of thermal power boiler tube clamp technology, and in particular to an adjustable-angle thermal power boiler tube clamp. Background Technology

[0002] Thermal power boilers are the core energy conversion equipment in thermal power plants. They use coal, natural gas, heavy oil, etc. as fuels, and release heat energy through fuel combustion in the furnace to heat the working fluid in the boiler into high-temperature and high-pressure steam. They are mainly composed of furnace, burner, heating surface, flue, etc. The core function is to convert the chemical energy of fuel into the thermal energy of steam to provide power for the rotation of steam turbine, which in turn drives generator to generate electricity. The equipment must meet the requirements of efficient combustion, full utilization of heat, and environmental protection emissions. It is a key hub connecting fuel combustion and power generation, and directly affects the efficiency, stability and environmental protection level of thermal power generation.

[0003] Tube clamps for thermal power boilers are key components for fixing pipes on the heating surface of thermal power boilers. They are made of high-temperature and corrosion-resistant materials and are suitable for the complex high-temperature environment inside the boiler. Through the clamping structure, the pipes are precisely fixed in the preset position. They also have the functions of limiting, shock absorption and anti-displacement. They can prevent the pipes from loosening or deforming due to thermal expansion and contraction and airflow impact, and prevent the risk of leakage.

[0004] Thermal power boiler pipes undergo complex displacements due to thermal expansion and contraction. Traditional fixed pipe clamps restrict the free expansion and contraction of the pipes, leading to stress concentration and weld cracking.

[0005] Therefore, it is necessary to provide an adjustable-angle tube clamp for thermal power boilers to solve the above-mentioned technical problems. Utility Model Content

The adjusting screw is threaded through the front of the limiting frame, and the rotating structure is used to rotatably connect the positioning plate to one end of the adjusting screw.
