Abstract

Aeroengine has the pipe-support structure that in-plane displancement compensates, comprise support, upper slide blocks, downslide motion block, clip, fixing bolt, plate nut, backing plate, sunk head rivet, cushion block A, cushion block B; Wherein: support is fixed on motor mounting edge or fitting seat; Fixing bolt is connected with plate nut with downslide motion block through clip, backing plate, upper slide blocks, support; Pipeline is arranged in clip; Upper slide blocks is connected with support with plate nut by sunk head rivet, fixing bolt.Advantage of the present utility model: make clip can be freely movable in the plane of certain limit, increases pipeline and installs compensation ability, and the inharmonious additional load brought to pipeline of casing and pipeline thermal expansion deformation when effectively can regulate engine operation.Can provide except axial support and the damping function of thinking other directions for pipeline.Can avoid arranging bit shift compensation structure on pipeline body, structure is simple.

Description

A kind of aeroengine has the pipe-support structure that in-plane displancement compensates
Technical field
The utility model relates to aeroengine field, particularly a kind of aeroengine has the pipe-support structure that in-plane displancement compensates.
Background technique
At present, the structure that aeroengine pipeline supporting structure adopts clip to be fixedly connected with support, be fixed on by pipeline on casing, clip applies omnidirectional support and damping function to pipeline, there is not relative displacement between pipeline and casing.But the pipeline worked in high temperature environments, inharmonious due to thermal expansion deformation between pipeline itself and casing, can there is relative displacement in pipeline, apply additional load to pipeline in particular directions and between casing, affect pipeline working life, also bring hidden danger to use safety.In this case, just require that pipe-support structure is while maintenance is to the support of the non-direction of displacement of pipeline and damping function, has in-plane displancement compensation ability, ensure the reliability of pipeline work.
For above present situation, a kind of pipe-support structure with displacement compensation capability need be designed, the form that this structure adopts support, spacer sleeve, slide blocks and backing plate to combine, while meeting the requirement of pipeline bit shift compensation, ensure pipeline reliably working.
Model utility content
The purpose of this utility model is to meet displacement compensation capability, and spy provides the pipe-support structure a kind of aeroengine with in-plane displancement compensation.
The utility model provides the pipe-support structure a kind of aeroengine with in-plane displancement compensation, it is characterized in that: described aeroengine has the pipe-support structure that in-plane displancement compensates, comprise support 1, upper slide blocks 2, downslide motion block 3, clip 4, fixing bolt 5, plate nut 6, backing plate 7, sunk head rivet 8, cushion block A9, cushion block B10;
Wherein: support 1 is fixed on motor mounting edge or fitting seat; Fixing bolt 5 is connected with plate nut 6 with downslide motion block 3 through clip 4, backing plate 7, upper slide blocks 2, support 1; Pipeline is arranged in clip 4; Upper slide blocks 2 is connected with support 1 with plate nut 6 by sunk head rivet 8, fixing bolt 5.
Upper slide blocks 2 and downslide motion block 3 can be radial movable within the scope of the circular hole of support 1, and the activity of slide blocks and Circularhole diameter size, depend on the displacement amount of pipeline during engine operation.
By adjustment clip 4 internal diameter size, can meet fixing different tube diameters pipeline, clip 4, backing plate 7 are all with lining, and can prevent pipeline from touching mill, lining can be resistant to elevated temperatures rubber material.
The height of cushion block A9, cushion block B10 is greater than the thickness of support 1, and to ensure upon connection, upper slide blocks 2, downslide motion block 3 can be movable within the scope of the circular hole of support 1.
Upper slide blocks 2, downslide motion block 3 can be movable within the scope of the circular hole of support 1, make this supporting structure be provided with thermal compensation ability, the inharmonious additional load brought to pipeline of casing and pipeline thermal expansion deformation during effective adjustment engine operation.
Advantage of the present utility model:
Aeroengine described in the utility model has the pipe-support structure that in-plane displancement compensates, make clip can be freely movable in the plane of certain limit, increase pipeline and compensation ability is installed, and the inharmonious additional load brought to pipeline of casing and pipeline thermal expansion deformation when effectively can regulate engine operation.Can provide except axial support and the damping function of thinking other directions for pipeline.Can avoid arranging bit shift compensation structure on pipeline body, structure is simple.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is pipe-support structure structural representation aeroengine with in-plane displancement compensation.
