Various disadvantages be present in the pipe clamp structure and assembly method of above two form：1) the pipe clamp width of generally use is 60mm, respectively there is 20mm space at both ends after assembling, and the light pipe segment of total 100mm length can not weld fin, need to be in welding fin The light pipe of certain length is reserved during pipe.Such as the economizer hand that length is 10m, pipe clamp everywhere is typically provided with, that is, has 400mm's Pipe no longer can not effectively exchange heat after being coated by pipe clamp, account for the 4% of total length, reduce the heat exchange utilization rate of H type finned tubes；2) Both ends and the space of fin are 20mm after pipe clamp assembling, it is contemplated that the external force effect during rigging error and transport lifting, It is easily caused pipe clamp to move along tube length direction, the space increase of pipe clamp and fin, makes the excessive light without any safeguard measure Under the washing away of flue gas heavy wear occurs for pipe, and substantial amounts of engineering confirms that the abrasion of light pipe is to cause province's coal at pipe clamp The major reason of device leakage；3) after pipe clamp and pipe misplace, the pipe clamp that every pipe is arranged is uneven, can not ensure during installation Transverse pitch, the transverse pitch of local pipe row is varied, dust stratification easily occurs in pitch smaller part, pitch larger part is easily formed Smoke corridor, wear；4) economizer tube clamping structure is complicated, manufacture difficulty is high, rigidity needs further to be improved.

The content of the invention

In order to solve the above-mentioned technical problem mesh of the present utility model carries, there is provided one kind is simple in construction, manufacturing cost is low, applicable Property it is high, rigidity is good, be easily assembled, improve economizer hand service life, improve heat exchange efficiency, be easily installed maintenance boiler save The H type finned tube pipe clamp structures of coal device.

Technical scheme includes support beam or suspention beam, and at least a set of pipe clamp knot is connected with the support beam or suspention beam Structure, the pipe clamp structure are made up of at least two groups comb plate, comb joint groups arranged forwards, backwards along light pipe diameter, and the comb plate, comb joint group is by two pieces Comb plate, comb joint is formed, and semicircle tube seat is provided with a side of the comb plate, comb joint, and after the corresponding splicing of two pieces of comb plate, comb joints, formation, which has, to supply The pore that light pipe passes through, the both ends of two pieces of comb plate, comb joints are corresponding to weld.

Connected between two groups of comb plate, comb joint groups in the pipe clamp structure through connecting plate.

The connecting plate is connected between the end of two groups of comb plate, comb joint groups.

The spacing between two groups of comb plate, comb joint groups in a set of pipe clamp structure is 80~100mm.

Adjacent two clamp sleeve is interstructural at intervals of 2000~3000mm.

Beneficial effect：

The utility model has following advantage compared with traditional pipe clamp：1) quantity that comb plate, comb joint only needs respective tube to arrange is cut Groove is cut open, without punch forming, manufacturing process is simple, and welding job amount is small, is easy to assemble；2) due to two pieces of corresponding folders of comb plate, comb joint Dress forms pore, and it is only thickness of slab that it, which clamps thickness, directly can be installed between fin, without reserved 100mm light pipe straight sections, certainly During fin is matched somebody with somebody in dynamic makeup, build-up tolerance can be effectively controlled, ensures the finned tube accuracy of manufacture；3) due to no longer remaining in advance The light pipe segment of pipe clamp structure is installed, this part light pipe segment can be with normal mounting fin, and the fin at pipe clamp can participate in normally changing Heat, improve heat exchange efficiency；4) comb plate, comb joint can be directly arranged between two fins, and gap is small between fin, it is ensured that pipe clamp hangs down Straight degree, fixed with connecting plate between the end of two groups of comb plate, comb joint groups, both enhanced the rigidity of pipe clamp, and can ensures that pipe clamp will not be Larger movement occurs on optical tube length direction, avoids producing that pitch is excessive or the generation of too small phenomenon, so as to mitigate transporting and hoisting Or the abrasion of local dust stratification or smoke corridor to light pipe.5) pipe clamp structure of the present invention can be connected realization branch with support beam in bottom Support, also realization lifting can be connected with hoisting beam at top, very flexibly.
