Abstract
The invention provides a limiting structure for an S-shaped piping system, which is used for preventing pipes of the piping system from being deformed by longitudinal heating under the condition that S-shaped pipes are long in the horizontal direction, and ensuring the thermal efficiency of a boiler. The limiting structure comprises S-shaped pipes which are arranged horizontally, wherein the horizontal segments of the S-shaped pipes are long; the upper layers and the lower layers of the S-shaped pipes are hoisted on upper transverse beams through hoisting assemblies; and the hoisting assemblies are positioned at the middle positions of the horizontal segments of the S-shaped pipes. The limiting structure is characterized in that limiting blocks are arranged between the upper layers and the lower layers at the two ends of the horizontal segments of the S-shaped pipes at certain intervals; the upper sides of the limiting blocks are connected with upper layer S-shaped pipes by welding; and the lower sides of the limiting blocks are connected with lower layer S-shaped pipes by welding.
Description
Technical field
The present invention relates to the syndeton technical field of boiler coiled pipe, be specially a kind of position limiting structure of snakelike piping.
Background technology
Large coal powder boiler has the snakelike piping of many horizontally disposed superheater, reheater or economizers, often adopt structures such as pipe clamp, column pipe or end portion supports to be used as fixture, but under the long situation of coiled pipe horizontal segment, be heated the back owing to there not being spacing point to cause pipe deformation between the pipe of piping is vertical, influence the thermal efficiency of boiler.
Summary of the invention
At the problems referred to above, the invention provides a kind of position limiting structure of snakelike piping, it guarantees coiled pipe under the long situation of level, the back pipe that is heated between the pipe of piping is vertical can not be out of shape, and guarantees the thermal efficiency of boiler.
A kind of position limiting structure of snakelike piping, its technical scheme is such: it comprises horizontally disposed coiled pipe, the horizontal segment of described coiled pipe is longer, be lifted on the crossbeam on top between the upper and lower layer of described coiled pipe by the lifting assembly, described lifting assembly is positioned at the medium position of the horizontal segment of described coiled pipe, it is characterized in that: be arranged at intervals with limited block between the upper and lower layer at the two ends of the horizontal segment of described coiled pipe, the upside of described limited block is welded to connect its upper strata coiled pipe, and the downside of described limited block is welded to connect the coiled pipe of its lower floor.
It is further characterized in that:
Described limited block is concrete, and set-up mode is as follows at interval: be provided with limited block after three vacancies at interval between the upper and lower layer of every end in the two ends of the horizontal segment of described coiled pipe, be separated with a vacancy between between the upper and lower adjacent limited block at the two ends of the horizontal segment of described coiled pipe.
After adopting structure of the present invention, the long coiled pipe of horizontal segment has gone out medium position and has been provided with outside the lifting assembly, be arranged at intervals with limited block between the going up of its horizontal segment two ends, the layer, it guarantees that coiled pipe is under the long situation of level, the back pipe that is heated between the pipe of piping is vertical can not be out of shape, and guarantees the thermal efficiency of boiler; In addition, at interval limited block is set between the going up of horizontal segment two ends, the layer, left for the horizontal segment two ends enough be subjected to thermal deformation surplus, the not situation that can interfere.
Description of drawings
Fig. 1 is a front view structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view structure enlarged diagram.
The specific embodiment
See Fig. 1, Fig. 2, it comprises horizontally disposed coiled pipe 1, the horizontal segment of coiled pipe 1 is longer, the crossbeam that is lifted on top by lifting assembly 2 between the upper and lower layer of coiled pipe 1 (does not draw among the figure, belong to existing mature technology), lifting assembly 2 is positioned at the medium position of the horizontal segment of coiled pipe 1, be arranged at intervals with limited block 3 between the upper and lower layer at the two ends of the horizontal segment of coiled pipe 1, the upside of limited block 3 is welded to connect its upper strata coiled pipe, and the downside of limited block 3 is welded to connect the coiled pipe of its lower floor.
Limited block 3 is concrete, and set-up modes are as follows at interval: 4 be provided with limited block 3 after three vacancies at interval between the upper and lower layer of every end in the two ends of the horizontal segment of coiled pipe 1, be separated with a vacancy 4 between between the upper and lower adjacent limited block 3 at the two ends of the horizontal segment of coiled pipe 1.
Claims (2)
