Embodiment 1

[0049] Such as Figure 1-5 Shown, a kind of natural gas overhead pipeline street straddling supporting device, comprises the natural gas overhead pipeline 1 spanning between two buildings; At least one steel wire rope 4 at the end and symmetrically arranged along the support member 2; wherein, the other end of the steel wire rope 4 is fixedly connected to the support member 2 so that the steel wire rope 4 has tension.

[0050]In the present invention, by setting the support piece 2 in the lower part of the natural gas overhead pipeline 1, and connecting the support piece 2 and the two ends of the natural gas overhead pipeline 1 through the steel wire rope 4, the support piece 2 is simultaneously connected with the natural gas overhead pipeline as a rigid bending member. The middle part of the pipeline 1 and the two end parts of the natural gas overhead pipeline 1 as tension members enable the support 2 to play a supporting role for the middle part of the natural gas overhead p...

Embodiment 2

[0092] The only difference from Example 1 is that, as Figure 7-11 The end connection device 5 includes a U-shaped frame 54, a turn-over limiting plate 55 arranged on the upper side of the U-shaped frame 54, a limiter connected to the upper part of the turn-over limit plate 55 and fixedly connected to the inner wall of the U-shaped frame 54. The block 58, the extruding plate 59 arranged on the lower side inside the U-shaped frame 54 and used to extrude the natural gas overhead pipeline 1 in the U-shaped frame 54, and the one-way limit mechanism 7 that can limit the downward movement of the extruding plate 59 , the flipping limiting plate 55 is rotatably connected to the wall of the U-shaped frame 54 through a rotating shaft 56 , and the rotating shaft 56 is also connected to the wall of the U-shaped frame 54 through a scroll spring 57 .

[0093] Such as Figure 8 and 10 As shown, because the long natural gas overhead pipeline 1 in the prior art adopts the scheme of adding su...

Abstract

The invention provides a natural gas overhead pipeline street crossing support device, and relates to the technical field of pipeline erection. The natural gas overhead pipeline street crossing support device comprises a natural gas overhead pipeline, a supporting part and at least one steel wire rope, wherein the natural gas overhead pipeline is arranged between two buildings in a crossing mode,the supporting part is connected with the lower portion of the middle of the natural gas overhead pipeline, the at least one steel wire rope is connected with the two ends of the natural gas overheadpipeline and is symmetrically arranged along the supporting part, and the other ends of the steel wire ropes are fixedly connected with the supporting part to enable the steel wire ropes to have tension. Compared with the prior art, the capacity of a natural gas street crossing pipeline itself is effectively increased, and no external measures are adopted or the external measures are adopted as little as possible; the crossing distance of the overhead pipeline is effectively increased, and for a street which exceeds 5-6m of the crossing limit of an original pipeline, the crossing can be easilycompleted; due to the fact that construction is not carried out on the user wall and the ground, the construction site coordination work and difficulty due to adopting other measures are effectivelyreduced; and the natural gas overhead pipeline street crossing support device is simple and convenient to manufacture and construct, easy to operate, easy to master and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of pipeline erection, in particular to a street-crossing support device for overhead natural gas pipelines. Background technique [0002] Existing natural gas low-pressure garden overhead piping has the following characteristics when crossing the street: [0003] (1) Pipes and fittings: the pipe diameter is small, mostly between DN32-DN65, generally not larger than DN80, and the radius of pipe fittings such as elbows is small. The rigidity and bending resistance of the pipeline itself are small. Referring to the "Code for Construction and Quality Acceptance of Urban Gas Indoor Engineering" CJJ94-2009, the support spacing of DN32-DN65 overhead pipelines is 3-6m, and the span of the pipeline itself is relatively small. [0004] CJJ94-2009 bracket spacing (m) DN65 6 DN50 5 DN40 4.5 DN32 4 [0005] Span requirements: The span generally does not exceed 12m. According to th...
