Description

Technical Field

[0001] The invention relates to the technical field of boilers, in particular to the technical field of serpentine pipe installation, and specifically is a boiler serpentine pipe fixing device. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy in the fuel, electrical energy, and steam, high-temperature water or organic heat carrier with a certain amount of thermal energy output by the boiler. In large boilers, the serpentine pipe systems such as superheaters and economizers in the boiler flue are sometimes supported between the walls, and the pipe system is composed of several circles of pipes. The serpentine pipe systems such as superheaters and economizers in the boiler flue sometimes adopt a suspended structure. During the operation of the boiler, it is washed by high-temperature flue gas, causing thermal expansion and shaking of the pipe system. The previous solution used several fixed limit devices at the same row of elbows. Due to certain errors in the installation process of the boiler, the reserved gap sizes are different, and the expansion and limiting functions cannot be well played.

[0003] However, most of the existing serpentine pipes inside the boiler flue are fixed by welding, which makes the serpentine pipes more troublesome to maintain and disassemble. In addition, the serpentine pipes are easily shaken by the impact of flue gas during use, resulting in damage to the welding parts, thereby reducing the service life of the serpentine pipes.

[0021] In a preferred embodiment, support plates 11 are fixedly provided at both ends of the base 1, and a threaded rod 12 is rotatably provided on the support plate 11. The upper end of the threaded rod 12 passes through the arc pressure plate 6, and the threaded rod 12 is threadedly connected to the arc pressure plate 6. When the threaded rod 12 rotates, the arc pressure plate 6 can be raised and lowered, thereby realizing the installation and disassembly of the serpentine tube body 2.

[0022] In a preferred embodiment, sprockets 13 are fixedly provided at the top ends of the two threaded rods 12, a chain 14 is provided between the two sprockets 13, and a handle 15 is fixedly provided at the upper end of one of the sprockets 13. The rotation of the handle 15 drives one of the sprockets 13 to rotate, and then the chain 14 drives the other sprocket 13 to rotate, so that the two threaded rods 12 rotate synchronously.

[0023] In a preferred embodiment, a support column 16 is fixedly provided at the bottom end of the arc-shaped shock-absorbing plate 8, and the bottom end of the support column 16 is fixedly provided on a buffer plate 17 inside the base 1, and a first buffer spring 18 is fixedly provided at the bottom end of the buffer plate 17. The side wall of the placement groove 7 is provided with a groove for the arc-shaped shock-absorbing plate 8 to move. When the arc-shaped shock-absorbing plate 8 is squeezed, the buffer plate 17 is squeezed by the support column 16, and the buffer plate 17 squeezes the first buffer spring 18 to achieve buffering of the serpentine tube body 2.

[0024] In a preferred embodiment, a guide rod 19 is fixedly provided inside the mounting groove 10, a moving block 20 is slidably provided on the guide rod 19, a second buffer spring 21 is fixedly provided on one side of the moving block 20, and the moving block 20 squeezes the second buffer spring 21 when moving along the guide rod 19.

[0026] Working principle of the present invention:

[0027] When the serpentine tube body 2 is installed, one of the sprockets 13 is driven to rotate by the handle 15. When the sprocket 13 rotates, the other sprocket 13 is driven to rotate by the chain 14, so that the two threaded rods 12 rotate synchronously. When the threaded rod 12 rotates, the arc pressure plate 6 moves upward, and the bottom end of the serpentine tube body 2 is placed in the placement groove 7 at the upper end of the base 1. The bottom end of the serpentine tube body 2 contacts the arc damping plate 8, and then the handle 15 is rotated in the opposite direction to make the arc pressure plate 6 move downward, and the bottom end of the arc pressure plate 6 contacts the upper end of the serpentine tube body 2. As the arc pressure plate 6 continues to press downward, the arc pressure plate 6 can press the serpentine tube body 2 tightly in the placement groove 7, so that the arc damping plate 8 drives the buffer plate 17 to move downward and squeeze the first buffer buffer 18. When the arc pressure plate 6 moves in the vertical direction, the slider 5 can move inside the slide groove 4. In order to prevent the slider 5 from sliding out of the slide groove 4, a T-type slider and a T-type slide groove can be selected;

[0028] During use, if the serpentine tube body 2 is shaken by the impact of smoke, the bottom end of the serpentine tube body 2 squeezes the arc-shaped shock-absorbing plate 8, and the upper end of the serpentine tube body 2 hits the arc-shaped pressure plate 6. When the arc-shaped shock-absorbing plate 8 is squeezed, it squeezes the buffer plate 17 through the support column 16, and the buffer plate 17 squeezes the first buffer spring 18. When the arc-shaped pressure plate 6 is impacted, it pulls the moving block 20 to move through the connecting rod 9. When the moving block 20 moves, it squeezes the second buffer spring 21, and the buffering of the first buffer spring 18 and the second buffer spring 21 is used to reduce the shock of the serpentine tube body 2.
