Description

Technical Field

[0001] This invention relates to a support device, and more particularly to a support device for X-ray inspection of narrow weld seams in aero-engine casing plates, belonging to the field of aero-engine maintenance and repair process equipment design and manufacturing technology. Background Technology

[0002] The air intake is the flow path through which air is drawn into an aero-engine, and it is one of the "five major components" of an aero-engine. The air intake casing assembly is an important part of the aero-engine air intake. It is located at the front of the engine and mainly includes support plates, adjustable blades, and load-bearing rings. During engine operation, it can introduce a sufficient amount of air into the compressor with minimal flow loss. Therefore, the quality of the air intake casing assembly directly affects the normal operation of all parts of the aero-engine. If, during use, the air intake casing assembly develops faults such as cracked or chipped support plates or detached adjustable blades, it can easily cause serious damage to the engine, leading to a major flight accident with incalculable losses.

[0003] Since the replacement of the intake casing assembly support plate involves in-situ electron beam welding, the quality of the weld needs to be inspected by X-ray in-situ replacement support plate in the intake casing. The weld length should be about 10mm, the width about 1mm, and the thickness about 1.5mm.

[0004] Existing X-ray inspection methods involve placing the inspected part within an effective radiographic field and performing vertical radiographic inspection. However, this approach has several drawbacks: First, the inspection parameters are insufficient to effectively detect weld defects; second, when replacing a narrow weld on the support plate in its original position within the intake casing, the outer ring of the intake casing and other support plates obstruct the weld during vertical radiographic inspection under current conditions; third, the X-ray machine head is too large to be positioned directly above the weld; and fourth, the horizontal and vertical angles of the replacement support plate weld cannot be guaranteed, resulting in ineffective inspection results. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a support device for X-ray inspection of narrow welds on the support plate of an aero-engine casing, which can ensure an effective radiographic angle for the narrow welds of the in-situ replacement support plate and accurately and effectively detect defects in the narrow welds of the in-situ replacement support plate.

[0006] The technical solution adopted to solve the above-mentioned technical problems is: a support device for X-ray inspection of narrow weld seams of aero-engine casing plates, the support device including a base frame, an adjustment component and a support fixing structure, the support fixing structure being arranged on the base frame; during the X-ray inspection of narrow weld seams of aero-engine casing plates, the irradiation angle of the aero-engine casing plate fixed on the support fixing structure in the horizontal and / or vertical directions is adjusted to a specified position by the adjustment component.

[0007] Furthermore, the support device also includes a mobile trailer, on which the base frame is arranged.

[0008] A preferred embodiment of the above solution is that the mobile trailer includes a frame, a mop, and a set of casters, the mop being fixedly mounted on the frame, the set of casters being fixedly mounted on the bottom of the frame, and the base frame being arranged on the frame.

[0009] Furthermore, the base frame includes a base frame, a bogie, and a support frame. The support frame is fixed to the base frame via the bogie. The base frame is detachably fixed to the mobile trailer. The support fixing structure is supported on the support frame with the cooperation of the adjustment assembly.

[0010] In a preferred embodiment of the above scheme, the bogie includes a right-angled truncated cone and an adjusting connector. The adjusting connector is arranged on the side of the top of the right-angled truncated cone with adjustable rotation angle. The bogie is connected to the base frame through the bottom of the right-angled truncated cone, and the support frame is detachably connected to the adjusting connector.

[0011] Furthermore, the supporting and fixing structure is a casing fixing wheel, the aircraft engine casing support plate is arranged on the free end of the casing fixing wheel, and the other end of the casing fixing wheel is arranged on the support frame in an adjustable manner via the adjustment component for horizontal and / or vertical illumination angles.

[0012] In a preferred embodiment of the above scheme, the adjustment assembly includes at least a horizontal illumination angle adjustment device and a vertical angle adjustment device, and the casing fixing wheel is arranged on the support frame through the horizontal illumination angle adjustment device and the vertical angle adjustment device.

[0013] Furthermore, the adjustment assembly also includes an effective illumination angle infrared locator, which is arranged on the housing fixing wheel.

[0014] In a preferred embodiment of the above scheme, a connecting frame is also connected to the lower part of the receiver fixing wheel, the receiver fixing wheel is movably connected to the support frame through the connecting frame, and the horizontal transmission angle adjustment device and the vertical angle adjustment device lock the receiver fixing wheel through the connecting frame.

[0015] The beneficial effects of this invention are as follows: The technical solution provided in this application sets up a support device including a base frame, an adjustment component, and a support fixing structure, and arranges the support fixing structure on the base frame; then, during the X-ray inspection of the narrow weld seam of the aero-engine casing support plate, the irradiation angle of the aero-engine casing support plate fixed on the support fixing structure in the horizontal and / or vertical directions is adjusted to a specified position by the adjustment component. Since the aero-engine casing support plate fixed to the support fixing structure can be adjusted by the adjustment component during the X-ray inspection of the narrow weld seam of the aero-engine casing support plate, the effective irradiation angle of the narrow weld seam of the in-situ replacement support plate of the intake casing can be ensured, achieving the purpose of accurately and effectively detecting defects in the narrow weld seam of the in-situ replacement support plate, and thus judging whether there are welding defects such as incomplete fusion affecting the quality of the intake casing assembly. The repair weld seam of the aero-engine casing support plate inspected using the support device of this application has a high accuracy rate and is easy to operate, making it particularly suitable for X-ray inspection during the in-situ repair of the intake casing assembly support plate.
