Abstract
The utility model discloses a heat supply pipeline fixing support. A fixing support base is added at the bottom of a common fixing support, and is connected with a civil engineering buried piece in a welding way; the fixing support and the fixing support base are connected through a main fixing bolt and a rotation guide bolt; a sliding plate is arranged between the fixing support and the fixing support base; bolt holes and bolt grooves are drilled in a base plate of the fixing support and a support plate of the fixing support base in a matching way. As the fixing support and the fixing support base are connected through bolts, the displacement, along three directions, of a pipeline can be limited, the pipeline is limited to rotate along the X and Y axes, the pipeline is allowed to rotate round the Z axis, i.e., plane rotation is realized, thus the torque, in the Mz direction, of the fixing support is eliminated, and the problem that calculation is intransitable due to too-large Mz in the pipeline heat stress calculation is solved.
Description
Technical field
The utility model belongs to industrial working or industrial park heating facility, is to use at the pipeline industrial working heat supply pipeline fixed support larger than the long tube footpath.
Background technique
The long distance of current industrial working or industrial park, major diameter heat supply transfer line, pipeline is because expanded by heating is elongated, and pipeline can carry out extrusion-deformation to the elbow between two fixed supports.Common fixed support not only limits the displacement of heat supply pipeline in X-axis, Y-axis, three directions of Z axis, has also limited simultaneously the rotation of pipeline along X-axis, Y-axis, Z axis.Because common fixed support does not allow pipeline, do not rotate around Z axis, therefore support bracket fastened, horizontally rotating moment Mz can be larger, thereby can destroy fixing rack structure.
The model utility content
The utility model aims to provide a kind of heat supply pipeline fixed support that overcomes above-mentioned prior art deficiency, to solve that common support bracket fastened three received strength all can meet the demands but the problem that horizontal moment can not meet the demands.
The technological scheme of model utility: heat supply pipeline fixed support, in common fixed support bottom, increase the fixed support base, make it to be welded to connect with the civil engineering embedded part, by main fixing bolt, be connected with the rotary steering bolt between common fixed support and fixed support base; Between common fixed support and fixed support base, slide plate is set; On common fixed support base plate and fixed support base support plate, join auger shell keyhole and bolt slot.
The diameter design of main fixing bolt is determined after need calculating according to the size of fixed support horizontal force, guide blot doubles as the torque resistant bolt, its diameter design is definite after need calculating according to the size of the stressed distance of fixed support, and the permission angle of swing of guide blot groove need be carried out calculative determination according to pipeline thermal displacement, duct length etc.Main fixing bolt diameter is selected between M36～M56 according to stress analysis result of calculation; The guide blot diameter is selected between M24～M56 according to stress analysis result of calculation; The permission angle of swing of guide blot groove is best<and 8 °, finally according to result of calculation, determine.
But the utility model is Plane Rotation formula heat supply pipeline fixed support, operation characteristic is as follows: but Plane Rotation formula heat supply pipeline fixed support is owing to for bolt, connecting, therefore pipeline is rotated around main fixing bolt within the specific limits, but do not allow pipeline, on X-axis, Y-axis, three directions of Z axis, displacement is arranged, rotary steering bolt while restriction conduit is along the rotation of X-axis, Y-axis.Because pipeline can be rotated around Z axis, then eliminated the moment of fixed support in the Mz direction, reached the purpose that reduces the stressed distance of fixed support.
The utility model on existing support bracket fastened basis, for stressed less, the characteristics that plane moment is larger of fixed support in industrial working or industrial park heat supply pipeline, but the special Plane Rotation formula heat supply pipeline fixed support that proposes.
Therefore the utility model has the advantages that: due to mode with bolts between common fixed support and fixed support base, at the restriction conduit three direction displacement, restriction conduit allows pipeline to be rotated around Z axis along the rotation of X-axis, Y-axis the time, then eliminated the moment of fixed support in the Mz direction, solved that pipeline thermal Stress calculation Mz is excessive causes calculating intransitable problem.

In figure: the common fixed support of 1-, 2-slide plate, 3-master's fixing bolt, 4-rotary steering bolt, 5-fixed support base, 6-cold conditions pipeline mounting point, deformation curve after the hot expansion of the common fixed support of 7-, but deformation curve after the hot expansion of 8-Plane Rotation fixed support, the 9-sliding support, 10-fixed support, d1-master's fixing bolt diameter, the d2-rotary steering diameter of bolt, θ-bolt slot allows angle of rotation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in FIG. 1 to 3, but the utility model is Plane Rotation formula heat supply pipeline fixed support, common fixed support (1), fixed support base (5), slide plate (2), main fixing bolt (3) and rotary steering bolt (4), consist of, rotary steering bolt (4) doubles as the torque resistant bolt.Fixed support base (5) is arranged under fixed support (1), between common fixed support (1) and fixed support base (5), slide plate (2) is set, common fixed support (1) utilizes main fixing bolt (3) to be connected with rotary steering bolt (4) with fixed support base (5).The dunnage of the base plate of common fixed support (1) and fixed support base (5) is joined auger shell keyhole and bolt slot.
Common fixed support (1) can rotate around main fixing bolt (3) in the scope that is less than the θ angle.Main fixing bolt (3) diameter d 1 is preferably M36～M56; Rotary steering bolt (4) diameter d 2 is preferably M24～M56; The permission rotation angle θ of guide blot groove is preferably<and 8 °.Main fixing bolt (3) diameter d 1=42 ㎜ for example, guide blot diameter d 2=30 ㎜, the permission rotation angle θ of guide blot groove=6 °.
As shown in Figure 4, Figure 5, house-service gas pipe is in plane Z font layout, and the mounting bracket of pipeline is fixed support (10) and sliding support (9), and cold conditions pipeline mounting point (6) as shown in the figure.Expanded by heating distortion after conduit running, when fixed support (10) adopts common fixed support, because part does not allow the pipeline rotation, after the hot expansion of common fixed support, as shown in the figure, common fixed support bears the horizontal torsion moment that pipe deforming produces to deformation curve (7); When fixed support (10) but adopt Plane Rotation formula heat supply pipeline fixed support, but because allowing pipeline, Plane Rotation formula heat supply pipeline fixed support carries out certain rotation around the fixed support center, but after the hot expansion of Plane Rotation fixed support, as shown in the figure, fixed support does not bear the horizontal torsion moment produced because of pipe deforming to deformation curve (8).
