Abstract

The invention relates to a horizontal pipeline limiting device and a horizontal pipeline limiting method. The horizontal pipeline limiting device comprises an outer pipe and an inner pipe, wherein the inner pipe is embedded into the outer pipe in a rotatable manner; the upper end of the inner pipe is fixedly connected with the outer surface of a horizontal pipeline to be limited; the lower end of the outer pipe is fixedly connected with a civil engineering structural member; and a gap is reserved between the upper end of the outer pipe and the outer surface of the horizontal pipeline to be limited. The outer surface of the horizontal pipeline to be limited is connected with the upper end of the inner pipe, and the inner pipe is embedded into the outer pipe in the rotatable manner; meanwhile, the lower end of the outer pipe is fixedly connected with the civil engineering structural member, and the gap is reserved between the upper end of the outer pipe and the outer surface of the horizontal pipeline to be limited; therefore, the linear displacement of the horizontal pipeline to be limited in both the radial direction and the axial direction is restricted (but the angular displacement cannot be restricted); as the axial limitation and the radial limitation are at the same position, three-directional limitation can be realized without an error; and furthermore, the limiting device is convenient to manufacture, and occupies a short section of the horizontal pipeline to be limited.

Detailed description of the invention
As shown in Figure 6,7, a kind of horizontal pipe stopping means, including outer tube 10 and inner tube 20, said inner tube 20 is rotatable Be embedded in outer tube 10, the upper end of said inner tube 20 with treat that spacing horizontal pipe 1 outer surface is fixing and be connected, described outer tube 10 Lower end and civil engineering structure part 30 fixing be connected, and the upper end of described outer tube 10 and treating between spacing horizontal pipe 1 outer surface Leave spacing.
By treating that spacing horizontal pipe 1 outer surface is connected with the upper end of inner tube 20, and by the most embedding for inner tube 20 Be located in outer tube 10, be connected fixing for the lower end of outer tube 10 and civil engineering structure part 30 simultaneously, and the upper end of outer tube 10 with wait to limit Spacing is left, it is simple to inner tube 20 rotates, no matter so treating that spacing horizontal pipe 1 is radially between horizontal pipe 1 outer surface of position Or axially displacement of the lines all can restrained (but angular displacement does not retrains), due to axial limiting and the most spacing at same position, can Spacing free from errors to realize three-dimensional, and stopping means is easy to process, occupies and treats that spacing horizontal pipe 1 length is short, will not Occupy the locational space of other suspension and supports.
The upper end of said inner tube 20 with treat the laminating of spacing horizontal pipe 1 outer surface, and the upper end of inner tube 20 with treat spacing The welding of horizontal pipe 1 outer surface, with reference to table 1, described outer tube 10 length h and inner tube 20 length H meet following relation: outer pipe range Degree h=inner tube length H-treats that the outer diameter D/2-of spacing horizontal pipe treats the insulation thickness-reserved length of spacing horizontal pipe 1 Degree, length in reserve described in table 1 is 30mm, and length in reserve may select in the range of 20mm-50mm, has both guaranteed that outer tube 10 can be internally Pipe 20 plays good position-limiting action, is avoided that again outer tube 10 interference effect inner tube 20 rotates.Wherein, spacing horizontal pipe is treated Insulation thickness refer to treat the thickness of adiabator of spacing horizontal pipe 1 outer surface parcel, general treats spacing horizontal tube Road 1 is heat distribution pipeline, needs at outer wrapping adiabator, if without wrapping up heat insulating material, insulation thickness is zero.Described outer tube 10 Internal diameter 1mm-2mm bigger than the external diameter of said inner tube 20, to ensure that inner tube 20 can insert outer tube 10 smoothly.The lower end of described outer tube 10 Welding with civil engineering structure part 30, the lower end of said inner tube 20 contacts with civil engineering structure part 30 but does not welds, and wherein in table 1, k is weldering The height of seam.
Table 1
Air vent 110 is offered respectively on described outer tube 10 and inner tube 20.Welding process is discharged by described air vent 110 The gas of middle generation, the diameter of described air vent 110 is generally 20mm-30mm, it is ensured that smooth in exhaust and outer tube 10 and inner tube 20 Intensity.Air vent 110 on outer tube 10 described in the present embodiment mutually runs through with the air vent 110 in inner tube 20, makes inner tube Gas in 20 can preferably be discharged.
A kind of horizontal pipe limit method, comprises the steps:
Air vent 110 offered respectively by outer tube 10 and inner tube 20;
The lower end of outer tube 10 is welded with civil engineering structure part 30;
Inner tube 20 being embedded in outer tube 10, the lower end of said inner tube 20 contacts with civil engineering structure part 30 but does not welds, institute State the upper end of inner tube 20 and treat spacing horizontal pipe 1 outer surface laminating and weld, and the upper end of described outer tube 10 with treat spacing Horizontal pipe 1 outer surface between leave spacing.
This horizontal pipe limit method is simple to operate, and wherein above-mentioned steps can mutually be replaced according to practical operation demand, order Change, preferably press said sequence operation, air vent 110 offered respectively by outer tube 10 and inner tube 20, it is simple to the weldering in subsequent step Aerofluxus in termination process, no matter radially or axial displacement of the lines all can restrained (but angular displacement be not so treating spacing horizontal pipe 1 Constraint), by the horizontal pipe that the method is spacing, its axial limiting and radial direction are the most spacing at same position, can be free from errors real Existing three-dimensional is spacing, and occupancy level duct length is short, will not occupy the locational space of other suspension and supports.
Wherein, described outer tube 10 length and inner tube 20 length meet following relation: outer length of tube=inner tube length-treat is spacing The external diameter/2-of horizontal pipe treat the insulation thickness-length in reserve of spacing horizontal pipe, length in reserve is 20mm-50mm, treats The insulation thickness of spacing horizontal pipe refers to treat the thickness of the adiabator of spacing horizontal pipe 1 outer surface parcel.By outer tube 10 are arranged to meet above-mentioned relation with the length of inner tube 20, better assure that the RADIAL displacement treating spacing horizontal pipe 1 with Axially displacement of the lines all can be restrained, and angular displacement simultaneously is not retrained, and meets spacing demand.
Each technical characteristic of embodiment described above can combine arbitrarily, for making description succinct, not to above-mentioned reality The all possible combination of each technical characteristic executed in example is all described, but, as long as the combination of these technical characteristics is not deposited In contradiction, all it is considered to be the scope that this specification is recorded.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that, for those of ordinary skill in the art For, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention Protect scope.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
