[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] refer to Figures 1 to 4 As shown, a specific implementation of the top-opening hatch test device of the utility model comprises a frame 1, an adjustment slot 11 is opened on the frame 1, a hatch check member 3 and a strut 8 adjustment member 7 are respectively installed in the adjustment slot 11, two ends of the hatch check member 3 and the strut 8 adjustment member 7 are respectively passed through the two sides of the frame 1 and connected with nuts 9, so that the parts can fix the hatch check member 3 and the strut 8 adjustment member 7 under the locking action of the nuts 9, and because they are installed in the adjustment slot 11, the nuts 9 can be loosened according to the hatch to be tested as needed to adjust the positions of the hatch check member 3 and the strut 8 adjustment member 7, so as to facilitate the testing of hatches of different sizes.

[0027] The frame 1 is also connected to a hinge mounting part 6 on one side of the door verification part 3. One end of the hinge mounting part 6 passes through the side of the frame 1 and is coaxially connected to the angle plate 2. The door hinge 4 is connected to the hinge mounting part 6. The door hinge 4 is connected to the test door 5. The strut 8 is connected to the strut adjustment part 7. The strut 8 is selected from any one of an electric push cylinder, an air cylinder or a hydraulic cylinder. The piston rod end of the strut 8 is connected to the end of the test door 5 away from the door hinge 4, so that the strut 8 provides power to push the test door 5 to simulate the opening of the door. After being pushed by the strut 8, the test door 5 rotates along the hinge with the door hinge 4. The door verification part 3 is used to simulate the body part of the aircraft and to verify whether the test door 5 will cause interference when rotating.

[0028] Working principle and its effect:

[0029] When using this device, first adjust the test cabin door 5 to a position that matches its actual position, install the cabin door hinge 4 and then adjust the hinge mounting part 6, rotate the hinge mounting part 6 to a specified angle, and adjust the angle according to the angle indication of the angle dial 2 when adjusting the angle. The scale 1 shown on the angle dial 2 is 1°, and continue to install the test cabin door 5. After the installation is completed, adjust the direction of the outer surface of the test cabin door 5 relative to the installation position of the cabin door hinge 4 to be parallel to the outer surface of the frame 1. At this time, the test cabin door 5 rotates and then drives the hinge mounting part 6 to rotate synchronously through the cabin door hinge 4. The rotation angle data can be obtained according to the angle dial 2. The angle data is equivalent to the offset angle between the cabin door and the installed aircraft body. If the actual cabin door is not a planar shape, it is regarded as the highest point of the edge that contacts the actual body intersecting as a plane.

[0030] After the adjustment is completed, the position of the hinge mounting member 6 is fixed by the nut 9. Then the door check member 3 is adjusted, and its upper surface needs to be flush with the highest vertex of the test door 5. At this time, the door check member 3 represents the actual state of the aircraft fuselage and the upper end of the door, so as to detect whether the test door 5 will interfere with the fuselage during the opening process.

[0031] After the states of the above-mentioned components are adjusted, the strut 8 provides power, thereby realizing the movement state of the door opening detection. In addition, the strut 8 is used as the power source, so the strut 8 of different lengths can be selected according to the form and size of different test doors 5. The struts 8 of different lengths will affect the position of the installation point. Therefore, the test door 5 is taken as a reference here, and the installation point of the strut 8 of the door is first determined. After the strut 8 is selected based on this installation point, it is first installed on the door and then on the frame 1. Since the frame 1 is provided with an adjustment groove 11 for the installation of the strut 8 adjustment member 7, the installation position of the strut 8 adjustment member 7 can be conveniently adjusted up and down. According to this method, the position of the strut 8 adjustment member 7 on the frame 1 is determined, and the strut 8 provides power to simulate the rotation of the test door 5 along the hinge with the door hinge 4 after being pushed by the strut 8. The door verification member 3 is used to simulate the body part of the aircraft and to verify whether the test door 5 will cause interference when rotating.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
