Description

Technical Field

[0001] This utility model belongs to the field of aviation inspection technology, and in particular is a device for detecting the installation gap of an aircraft airtight door. Background Technology

[0002] Airtight doors are a crucial component of aircraft, ensuring the airtightness of the cabin. Their installation clearance is a direct indicator of the door's installation effectiveness. Airtight door loading equipment applies different forces to both sides of the door to check the installation clearance. It must be fixed to an aircraft ramp, where the installation clearance is narrow. Traditional equipment, when loading the door, applies "push" and "pull" forces to both the inside and outside of the door, requiring adjustment of the loading position. This adjustment necessitates manual control of the door's opening and closing, and the ramp's raising and lowering to switch between the two states, increasing the risk of collision between the aircraft and the loading device. Utility Model Content

[0003] The purpose of this invention is to provide a device for detecting the installation gap of an aircraft airtight door.

[0004] This utility model has a simple structure and is easy to use.

[0005] The technical solution of this utility model is: a device for detecting the installation gap of an aircraft airtight door, including a bracket, a telescopic drive rod on the bracket, a 90° deflection support at the end of the telescopic drive rod, the 90° deflection support being connected to a sensor mounting base via an adjusting rod, and a push state sensor and a pull state sensor respectively installed on the front and rear sides of the sensor mounting base.

[0006] In the aforementioned device for detecting the installation gap of aircraft airtight doors, a set of lifting wheels is provided at the bottom of the bracket.

[0007] In the aforementioned device for detecting the installation gap of an aircraft airtight door, the telescopic drive rods are arranged in a pair and are parallel to each other.

[0008] In the aforementioned device for detecting the installation gap of aircraft airtight doors, the telescopic drive rod is an electric actuator.

[0009] In the aforementioned device for detecting the installation gap of an aircraft airtight door, the adjusting rod is a double-ended stud.

[0010] In the aforementioned device for detecting the installation gap of aircraft airtight doors, the support frame is a steel frame structure.

[0011] The advantages of this invention are: It solves the problem of the loading joint being too high to extend beyond the lower edge of the airtight door due to its combination of a double-headed stud lifting structure and a 90° deflection support. It eliminates the need for manual control of the airtight door's opening and closing, or the lifting and lowering of the inclined platform, to switch between the "push" and "pull" states. The entire adjustment process is reliable, visible, and controllable.

[0012] This utility model is easy to move and simple to operate. The main body is made of welded steel frame, which is simple to manufacture. It uses a structure that conforms to the principles of human mechanics, making it flexible to move and easy to use.

[0013] This utility model has a simple structure, conforms to the principles of ergonomics, requires no manual adjustment of the airtight door and inclined platform, and is operated manually by the operator. The entire process is easy to observe. It is simple in structure, easy to manufacture, easy to install and use, and has a simple principle. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0017] Example 1. A device for detecting the installation gap of an aircraft airtight door, configured as follows: Figure 1 As shown, the device includes a bracket 7, on which a telescopic drive rod 6 is provided. The end of the telescopic drive rod 6 is provided with a 90° deflection support 5. The 90° deflection support 5 is connected to the sensor mounting base 3 via an adjusting rod 4. A push state sensor 2 and a pull state sensor 1 are respectively installed on the front and rear sides of the sensor mounting base 3.

[0018] The bottom of the bracket 7 is equipped with a set of lifting wheels 8.

[0019] The telescopic drive rods 6 are arranged in a pair, and the two telescopic drive rods 6 are parallel to each other.

[0020] Telescopic drive rod 6 is an electric actuator.

[0021] Adjusting rod 4 is a double-ended stud.

[0022] Support 7 is a steel frame structure.

[0023] Push status detection:

[0024] Move the loading inspection device onto the inclined platform 10;

[0025] Raise the lifting wheel assembly 8 to its highest position so that the bracket 7 is in direct contact with the inclined platform floor 10;

[0026] Connect bracket 7 to inclined platform floor 10;

[0027] The height requirement for the "push" state is achieved by adjusting the height of the double-ended stud 4.

[0028] By adjusting the preset value of the push sensor 2, the electric push rod is controlled to push the airtight door 9. When the pushing force is constant, the installation gap of the airtight door 9 is checked.

[0029] When the pressure reading meets the requirements, it is confirmed that the airtight door 9 is installed without any problems;

[0030] When the pressure reading does not meet the requirements, the installation gap on the airtight door 9 is manually adjusted until the pressure reading meets the requirements.

[0031] Manipulate electric actuator 6 to return it to its initial position.

[0032] Pull status detection:

[0033] By adjusting the 90° deflection support 5, it can be rotated 90 degrees;

[0034] Control the electric actuator to bring it to its maximum extension position;

[0035] By adjusting the 90° deflection support 5, it is restored to its original angle, and the tension sensor 1 is used to hook the airtight door 9.

[0036] The electric push rod 6 is retracted and pulled by adjusting the preset value of the pull sensor 1. When the pulling force is constant, the installation gap of the airtight door is checked.

[0037] When the pressure reading meets the requirements, it is confirmed that the airtight door 9 is installed without any problems;

[0038] When the pressure reading does not meet the requirements, the installation gap on the airtight door 9 is manually adjusted until the pressure reading meets the requirements.

[0039] The 90° deflection support 5 was adjusted again to rotate it 90 degrees.

[0040] Control the electric actuator 6 to retract it to its initial position;

[0041] Adjust the 90° deflection support 5 to restore its original angle.

[0042] Disconnect the support 7 from the inclined platform floor 10;

[0043] Lower the lifting wheel assembly 8 to its lowest position so that the support 7 is no longer in contact with the inclined platform floor 10; the test is now complete.
