Description

Technical Field

[0001] The utility model relates to the technical field of boarding bridge inspection, in particular to a boarding bridge inspector. Background Art

[0002] The three aircraft approach deceleration / stop devices and two infrared approach deceleration switches on the boarding bridge require regular maintenance and inspection. Daily inspections of these devices require the collaboration of at least two personnel. One person, standing on the ground, manually presses the device to verify the proper retraction and spring rebound. Another person, standing on the apron, uses an object to block the infrared proximity switches and verify their proper function and detection range.

[0003] The inspection process still requires multiple people, and it is impossible to accurately check the spring rebound force or directly measure the detection distance of the infrared pick-up deceleration. It is necessary to rely on experience to judge the aging fatigue of the spring and use a tape measure to measure whether the infrared detection distance is normal. For this reason, we provide a boarding bridge inspector. Utility Model Content

[0021] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0022] Please refer to Figures 1 to 3 As shown, the present invention provides an aircraft bridge inspection device, comprising a telescopic rod 1, the output end of which is fixedly connected to an adapter 2, one end of which is detachably connected to a retractor 3. An infrared distance sensor 4 is disposed within the adapter 2. During actual implementation, during inspection, the telescopic rod 1 is extended and retracted, thereby expanding the rubber on the aircraft bridge. After expansion, the rubber automatically retracts to detect the fatigue level of the spring. The retractor 3 is provided to conveniently hook into the hole of the rubber sleeve, and can simultaneously provide support and dragging depending on the mode of use. When distance measurement is required, the infrared distance sensor 4 can perform length measurement, thereby completing the length detection. The use of the infrared distance sensor 4 provides high detection accuracy.

[0023] Optionally, length scale lines are provided on the telescopic rod 1. In actual implementation, length scale lines are provided on the telescopic rod 1 to facilitate length observation and intuitive use.

[0024] Optionally, the adapter 2 has a cavity inside, and the infrared ranging sensor 4 is fixedly mounted in the cavity. A chip battery 21 is also provided inside the adapter 2 to power the infrared ranging sensor 4. In actual implementation, the chip battery 21 is embedded in the adapter 2 to facilitate installation. The chip battery 21 powers the infrared ranging sensor 4 and can be replaced if it runs out of power.

[0025] Optionally, the outer wall of the adapter 2 has external thread teeth, the outer wall of the hook 3 has internal thread teeth, and the adapter 2 is threadedly connected to the hook 3. In actual implementation, the threaded connection method is used to facilitate the assembly of the hook 3 and the adapter 2.

[0026] Optionally, the handle, front end and surface of the retractor 3 of the telescopic rod 1 are all provided with rubber 5, which is an insulating and pressure-resistant material. In actual implementation, the rubber 5 can play an insulating effect and effectively avoid the risk of electric shock when in use.

[0027] Optionally, the hook front end of the draw hook 3 has a magnet 6, which is used to absorb tools and parts for maintenance.
