Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pipeline measurement, and particularly relates to an auxiliary measurement tool for a long pipe of light material in an aviation cabin. BACKGROUND

[0002] In the field of spacecraft design, long light pipes, as core components for realizing high thrust-to-weight ratio and low system redundancy, play a key role in various spacecraft. Taking deep space probes with stringent mass constraints as an example, the propellant supply pipeline needs to meet the requirements of high-pressure transmission, low flow resistance coefficient and wide temperature range service of supercritical helium and hydrazine fuel under the constraint of low total mass. Such light long pipes are widely used in various systems of spacecraft: in satellite attitude control systems, they can reduce the moment of inertia and improve the response bandwidth of reaction flywheels; in space station heat pipe radiators, they can ensure the long-term stable operation of two-phase flow circulation systems due to their high thermal conductivity and high cycle fatigue life characteristics.

[0003] However, there are many problems in the conventional measurement method when measuring such light long pipes:

[0004] The long light pipe is small in mass and low in rigidity, and is prone to sagging and bending deformation under its own weight in a natural placement state. If it is directly placed on the ground or an ordinary support, the pipe shape will deviate from the actual installation state, resulting in significant deformation and inaccurate shape observation.

[0005] Existing measurement tools are mostly fixed structures and cannot adapt to the variable spatial orientation of light long pipes. The single-point or small number of support point clamping methods cannot stably clamp multiple branches, cannot adjust the clamping angle according to the bending changes and surface curvature of the pipe, and are prone to extrusion deformation of thin-walled light pipes, damaging the original shape of the pipe.

[0006] Therefore, there is an urgent need for a measurement tool that can solve the above problems to achieve more efficient and stable measurement of light long pipes. SUMMARY

[0010] Optionally, the lengthening piece is a telescopic rod.

[0011] Optionally, the lengthening piece comprises a sleeve and an inner tube, the inner tube slidingly telescoping in the sleeve and being fixed by a fixing structure.

[0012] Optionally, the clamping piece comprises a chuck, the chuck being movably connected with the main rod or the branch rod by a connecting piece.

[0013] Optionally, the base comprises a bottom plate, a connecting column being fixedly connected with the center of the bottom plate, the connecting column being connected with the bottom of the lengthening piece, and the bottom of the lengthening piece being detachably connected with the connecting column.

[0014] Optionally, a plurality of reinforcing ribs are fixedly connected between the connecting column and the bottom plate in the circumferential direction.

[0015] Optionally, the chuck can be universally rotated on the top of the main rod or the branch rod by the connecting piece.
