Embodiment Construction

[0018] The following combination Figure 1 ~ Figure 4 , a preferred embodiment of the present invention is described in detail.

[0019] Such as Figure 1 ~ Figure 3 As shown, the pairing fixture of the small-pitch tube row includes two pairing fixture assemblies connected concentrically through the connecting plate 5, and each pairing fixture assembly includes two inserting plates 2, which are arranged at the bottom ends of the two inserting plates 2 The supporting block 3 between them, and the fastening device 1 arranged between the top ends of the two inserting boards 2 .

[0020] Among them, such as Figure 4 As shown, the thickness of the insert plate 2 is smaller than the gap between adjacent pipes 4; and the interval width between the two insert plates 2 is set correspondingly to the tube row pitch, so that each insert Each plate 2 can be inserted from the gap between adjacent tubes 4 .

[0021] The supporting block 3 is arranged in a V shape or a U shape, so that t...

Abstract

The invention relates to a fitting clamp for a fine-pitch tube bundle, which comprises two fitting clamp assemblies concentrically connected through a connecting plate; each fitting clamp assembly comprises two insertion plates, a tray and a fastening device, wherein the tray is arranged between the bottom ends of the two insertion plates; the fastening device is arranged between the top ends of the two insertion plates; the thickness of each insertion plate is less than a gap between two adjacent pipes; and the spacing width between the two insertion plates and the pitch of the adjacent pipes are correspondingly arranged. The fitting clamp for the fine-pitch tube bundle can be suitable for the concentric fitting operation on the end part of the fine-pitch tube bundle in an integrated gasification combined cycle (IGCC) gasification furnace or a large-capacity circulating fluid bed (CFB) boiler, is convenient for welding and is capable of effectively ensuring the product manufacturing quality and cycle.

Description

technical field [0001] The invention relates to a pipe row alignment fixture, in particular to a pipe row alignment fixture for small pitches. Background technique [0002] At present, under the background of advocating energy saving and emission reduction, in addition to the higher and higher grades of power plant boilers, the structure of the internal heating surface components is gradually becoming more and more compact. With the development of new technologies such as IGCC (Integrated Gasification Combined Cycle) gasifiers and large-capacity CFB (Circulating Fluidized Bed) boilers, the increasingly narrow internal welding space has put forward higher requirements for manufacturing processes. [0003] At present, for the 300MW CFB boiler project, the panel superheater assembly is composed of 20 tubes with a diameter of 51mm arranged at a pitch of 63mm. In theory, the gap between adjacent tubes is only 12mm. Under such conditions, if there is no effective pipe row matchin...
