Background technique
At present, ultra supercritical unit main steam temperature advanced in the world has reached 600 DEG C, generating efficiency reaches 46%, if main steam temperature is brought up to more than 700 DEG C further, generating efficiency will close to even more than 50%, and this technology is exactly 700 DEG C of ultra supercritical power generation technology in Chinas of global power industry extensive concern.
Traditional horizontal pipe deferent portion pattern is three hole pipe clamps, as shown in accompanying drawing 4 and Fig. 5.After pipeline steam temperature meets or exceeds 700 DEG C, the ferrite that existing pipe clamp uses, martensite and austenite heat-resistance stainless steel material can not meet the requirement of usability, and the necessary working strength of pipe clamp is higher, the better high temperature resistant nickel base alloy of creep properties.Because the price of nickel-base alloy is extremely expensive, be ten times of traditional heat-resistant material price to decades of times, three traditional hole pipe clamp nickel-bass alloy material consumptions large (bolt and nut in two pipe clamping pieces, thermal insulation layer all needs to adopt nickel-base alloy), manufacturing process complexity (techniques such as thermoforming, heat treatment, welding, flaw detection need be adopted), cost of production is high, has been not suitable for applying in 700 DEG C of ultra-supercritical power generation technologies.In order to meet China's 700 DEG C of ultra-supercritical power generation technologies test needs, seeking a kind of novel structure, to manufacture 700 DEG C of simple, cost-saving high-temperature pipe U-tube folders particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of novel structure, manufactures 700 DEG C of simple, cost-saving high-temperature pipe U-tube folders.
The purpose of this utility model is achieved in that
A kind of 700 DEG C of high-temperature pipe U-tube folder, it comprises U-shaped steel band, V-type dunnage, two groups of connecting bolt assemblies, two groups of channel-section steels, two pieces of connecting bolt backing plates, two hexagon nuts, two hexagon thin nuts and load boatswain chair, the channel-section steel of two groups of lateral arrangement is connected with load boatswain chair, top, two ends, channel-section steel left and right arranges connecting bolt backing plate, hole is opened at connecting bolt backing plate center, described connecting bolt assembly comprises pull bar, U-nut, bearing pin and cotter pin, the epimere of pull bar is through connecting with described hexagon nut after the through hole of channel-section steel and connecting bolt backing plate and locking with described hexagon thin nut, the epimere of U-nut is the nut of opening upwards, the hypomere of U-nut is the U-shaped intermediate plate that Open Side Down, the nut of U-nut is threaded with the lower end of pull bar, the two ends of U-shaped steel band are embedded in the U-shaped intermediate plate of two U-nuts respectively, the attachment hole that two bearing pins insert U-shaped steel band two ends is respectively connected with U-shaped steel band, and lock with cotter pin, pipeline is longitudinally set up on U-shaped steel band, the V-type dunnage that channel-section steel is arranged downwards props up the top of pipeline.
Compared with prior art, the beneficial effects of the utility model are:
The utility model 700 DEG C of high-temperature pipe U-tube folders adopt U-shaped steel band to add double flute die formula, fit with pipeline Lower Half outer surface inside the U-shaped face of U-shaped steel band, increase the area of contact that pipe clamp and pipeline carry, reduce the localized stress of pipeline, thus prevent from causing localized injury to pipeline, stop traditional three hole pipe clamps simultaneously and taken off the possibility of carrying, carried more reliably for high-temperature pipe provides; U-shaped steel band and connecting bolt assembly joint are in outside thermal insulation layer, and the parts contacted with high-temperature pipe only have U-shaped steel band and V-type dunnage, thus substantially reduce the number the application of nickel-base material; V-type dunnage plays the role of positioning between pipeline and pipe clamp, do not carry by pipe load, though there is part to enter thermal insulation layer inside, without the need to adopting nickel-base material, adopts traditional exotic material; Pipe clamp in-site installation is easy with dismounting, only need carry out the simple operationss such as plug bearing pin, tightening nut and just can complete.Therefore these 700 DEG C of high-temperature pipe U-tube fixtures have novel structure, manufacture simple, cost-saving advantage.

Wherein:
U-shaped steel band 1, V-type dunnage 2, connecting bolt assembly 3, pull bar 3.1, U-nut 3.2, bearing pin 3.3, cotter pin 3.4, channel-section steel 4, connecting bolt backing plate 5, hexagon nut 6, hexagon thin nut 7, load boatswain chair 8, pipeline 9.
Embodiment
See Fig. 1 ~ Fig. 3, the one that the utility model relates to 700 DEG C of high-temperature pipe U-tube folders, it comprises U-shaped steel band 1, V-type dunnage 2, two groups of connecting bolt assemblies 3, two groups of channel-section steels 4, two pieces of connecting bolt backing plates 5, two hexagon nuts 6, two hexagon thin nuts 7 and load boatswain chair 8
Described load boatswain chair 8 is longitudinally arranged, before and after described load boatswain chair 8, two long sides respectively open a notch, weld, have bearing holes above described load boatswain chair after the channel-section steel 4 of two groups of lateral arrangement snaps in this notch respectively, be connected with root by suspension and support link, pipe loadings is effectively passed to root.Channel-section steel about 4 two ends welded top connecting bolt backing plate 5, hole is opened at connecting bolt backing plate 5 center.
Described connecting bolt assembly 3 comprises pull bar 3.1, U-nut 3.2, bearing pin 3.3 and cotter pin 3.4.The epimere of pull bar 3.1 is through connecting with described hexagon nut 6 after the through hole of channel-section steel 4 and connecting bolt backing plate 5 and locking with described hexagon thin nut 7.Described U-nut 3.2 adopts integrated machine to shape, and the epimere of U-nut 3.2 is the nut of opening upwards, and the hypomere of U-nut 3.2 is the U-shaped intermediate plate that Open Side Down, and the nut of U-nut 3.2 is threaded with the lower end of pull bar 3.1.
