Description

Technical Field

[0001] This invention relates to the field of foreign object detection technology, and more particularly to an assembled rotating arm structure for foreign object detection at airports. Background Technology

[0002] An airport foreign object detection vehicle (FODV) is a device used to detect foreign substances, debris, or objects on aircraft runways. It is commonly used for the maintenance of airport runway safety, as foreign objects pose a significant threat to the safety of airport flights. With the development of technology, in order to ensure the safe operation of flights, people have been committed to the development of vehicle-mounted swing arms and the research on their stability. This is to ensure that the detection unit carried by the swing arm can perform detection smoothly and efficiently. The use of the swing arm is inseparable from the swing arm system. The swing arm is usually combined with the swing arm to ensure the smooth extension and retraction of the swing arm. It can be said that the swing arm is the carrier for the long-length swing arm to work and detect foreign objects.

[0003] To increase the detection range, existing cantilever mechanisms mostly adopt telescopic structures. However, during foreign object detection at airports, gaps exist between the telescopic arm sections, causing the cantilever to sway during extension and retraction, resulting in slow extension and retraction speeds and affecting detection efficiency. Furthermore, excessive arm angles can easily occur, damaging the detection equipment. Summary of the Invention

[0004] The present invention aims to provide an assembled rotating arm structure for foreign object detection at airports, in order to overcome the shortcomings of the prior art. The technical problem to be solved by the present invention is achieved through the following technical solution.

[0005] An assembled rotating arm structure for foreign object detection at airports, mounted on a detection vehicle, comprises:

[0006] The base is used to connect to the inspection vehicle and serves as the mounting base for various components;

[0007] The rotating shaft assembly has two sets, which are rotatably connected to the two free ends of the base respectively. The base is equipped with a drive assembly for driving the rotating shaft assembly to rotate.

[0008] A cantilever frame is fixed to the rotating shaft assembly so that when the driving assembly drives the rotating shaft assembly to rotate, the cantilever frame drives the cantilever inside it to rotate and unfold.

[0009] It also includes a tensioning assembly mounted on the rotating shaft assembly. The tensioning assembly includes at least a traction member and a winding member. One end of the traction member is fixed to the end of the cantilever, and the other end of the traction member is wound or unwound through the winding member.

[0010] Furthermore, the base includes a U-shaped frame composed of an upper fixed plate, a fixed base plate, a front vertical plate, and a rear vertical plate connected in sequence on their sides. At least one set of mounting bases for connecting with the testing vehicle is also installed at the bottom of the fixed base plate.

[0011] Furthermore, the rotating shaft assembly includes a shaft member and a rotating member, the rotating member being mounted on the base, and the shaft member being fixedly connected to the rotating member.

[0012] Furthermore, the rotating component includes double-row cylindrical roller bearings and tapered roller bearings, which are respectively mounted on the upper fixed plate and the fixed base plate. The rotating component includes a main shaft and an arm shaft connected to the main shaft via a coupling.

[0013] Furthermore, the cantilever frame includes an upper fixed frame and a lower fixed frame fixed to the arm shaft, the upper fixed frame and the lower fixed frame forming a frame structure, in which the cantilever sleeve is installed.

[0014] Furthermore, the cantilever sleeve includes an upper cantilever plate and a lower cantilever plate, which together form an opening for accommodating the cantilever. The cantilever sleeve is fixedly connected to the upper and lower fixing frames.

[0015] Furthermore, the tensioning assembly includes an auxiliary rod mounted on the arm shaft. The auxiliary rod is inclined and a mounting plate is installed between it and the arm shaft. A left rope plate and a right rope plate are respectively provided on the top two sides of the mounting plate. The left rope plate and the right rope plate are fixed together by screws. A motor is fixedly mounted on the left rope plate or the right rope plate, and the shaft end of the motor is located between the left rope plate and the right rope plate.

[0016] Furthermore, the traction component is a steel wire rope, one end of which is wound around the shaft end of the motor, and its free end is connected to the cantilever inside the cantilever frame.

[0017] Furthermore, it also includes a corner detection component, which is installed on the base and is used to detect and alarm when the cantilever frame rotates to a preset position.

[0018] Furthermore, the corner detection component includes a torque sensor and a microcontroller electrically connected to the torque sensor. The torque sensor is equipped with a torque probe, and the microcontroller is also electrically connected to an alarm.

[0019] The embodiments of the present invention have the following advantages:

[0020] The assembled swing arm structure for airport foreign object detection provided in this embodiment of the invention uses a wire rope tensioning structure to control the wire rope to be smoothly extended and retracted synchronously by a motor during the outward extension or retraction of the cantilever, so that a certain tension is always maintained between the main shaft of the swing arm and the end of the cantilever.

[0021] This makes the connection between the cantilever and the cantilever sleeve more secure, while reducing vibration during the rotation and extension of the cantilever, accelerating the extension and retraction speed of the cantilever, preventing bending and swaying, and improving the efficiency of the inspection work.

[0022] Secondly, the torque sensor is set up so that when the torque probe is fully extended, it is subjected to force and twists, thereby triggering the torque sensor. The torque sensor transmits a signal to the microcontroller, which then controls the alarm to sound, thereby reminding the inspection personnel that the cantilever has been extended to the preset position and the inspection work can be carried out. This avoids the cantilever sleeve being extended too much, which could cause damage to the rotating arm structure or inspection unit, thus ensuring the efficient operation of the inspection work.

Detailed Implementation

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] Reference Figure 1-4 An assembled rotating arm structure for foreign object detection at airports, mounted on a detection vehicle, comprises:

[0030] The base is used to connect to the inspection vehicle and serves as the mounting base for various components;

[0031] Specifically, the aforementioned base includes a U-shaped frame consisting of an upper fixed plate 3, a fixed base plate 9, a front vertical plate 10, and a rear vertical plate 25 connected sequentially on their sides. At least one set of mounting bases 16 for connecting with the inspection vehicle is also installed at the bottom of the fixed base plate 9. In this embodiment, two sets of mounting bases 16 are provided to enhance the installation stability of the base.

[0032] The rotating shaft assembly has two sets, which are rotatably connected to the two free ends of the base, and the base is equipped with a drive assembly for driving the rotating shaft assembly to rotate.

[0033] Furthermore, in this invention, the rotating shaft assembly includes a shaft member and a rotating member, the rotating member is mounted on the base, and the shaft member and the rotating member are fixedly connected.

[0034] Specifically, the rotating component includes a double-row cylindrical roller bearing 6 and a tapered roller bearing 15, which are respectively mounted on the upper fixed plate 3 and the fixed base plate 9. The rotating component includes a main shaft 1 and an arm shaft 12 connected to the main shaft 1 via a coupling 5. In this embodiment, a drive motor is installed on the base to drive the main shaft 1 to rotate, so that the cantilever frame can be rotated and opened. In other embodiments, those skilled in the art know that a hydraulic cylinder or a pneumatic cylinder can be used to directly drive the cantilever frame to make it rotate circumferentially along the arm shaft 12.

[0035] The cantilever frame is fixed to the pivot assembly so that when the drive assembly drives the pivot assembly to rotate, the cantilever frame drives the cantilever inside it to rotate and unfold.

[0036] Furthermore, the cantilever frame in this invention includes an upper fixed frame 13 and a lower fixed frame 14 fixed to the arm shaft 12. The upper fixed frame 13 and the lower fixed frame 14 form a frame structure. A cantilever sleeve is installed in the frame structure. The cantilever sleeve is used to install the cantilever. A telescopic mechanism can be installed on the cantilever sleeve to drive the telescopic movement of the cantilever. In this embodiment, a hydraulic cylinder can be installed on the cantilever sleeve to drive the cantilever.

[0037] More specifically, in this embodiment, the cantilever sleeve includes an upper cantilever plate 7 and a lower cantilever plate 8. The upper cantilever plate 7 and the lower cantilever plate 8 form an opening for accommodating the cantilever. The cantilever sleeve is fixedly connected to the upper fixing frame 13 and the lower fixing frame 14.

[0038] It should be noted that a tensioning assembly is also included, which is installed on the rotating shaft assembly. The tensioning assembly includes at least one traction member and one winding member. One end of the traction member is fixed to the end of the cantilever, and the other end of the traction member is wound or unwound through the winding member.

[0039] Specifically, the tensioning assembly includes an auxiliary rod 2 mounted on the arm shaft 12. The auxiliary rod 2 is inclined and a mounting plate 11 is installed between it and the arm shaft 12. A left rope plate 17 and a right rope plate 19 are respectively provided on the top two sides of the mounting plate. The left rope plate 17 and the right rope plate 19 are fixed together by a screw 18. A motor 20 is fixedly mounted on the left rope plate 17 or the right rope plate 19. The shaft end of the motor 20 is located between the left rope plate 17 and the right rope plate 19. In this embodiment, a winding drum can be fixed to the shaft end of the motor 20 to fix the wire rope 4. In this embodiment, the motor 20 is a stepper motor or a servo motor to ensure precise control of the wire rope winding.

[0040] Furthermore, in this embodiment, the traction component is a steel wire rope 4, one end of which is wound around the shaft end of the motor 20, and its free end is connected to the cantilever inside the cantilever frame. In other embodiments, those skilled in the art can use nylon rope to achieve the same technical effect.

[0041] Specifically, in this invention, a wire rope tensioning structure is used to control the wire rope to be smoothly extended and retracted synchronously by a motor during the outward extension or retraction of the cantilever.

[0042] This makes the connection between the cantilever and the cantilever sleeve more stable, while reducing vibration during the rotation and extension of the cantilever, accelerating the extension and retraction speed of the cantilever, preventing bending and swaying, and improving the efficiency of the inspection work.

[0043] Furthermore, the present invention also includes a corner detection component, which is mounted on the base and is used to detect and alarm when the cantilever frame rotates to a preset position.

[0044] For example, the aforementioned corner detection component includes a torque sensor 23 and a microcontroller 24 electrically connected to the torque sensor 23. The torque sensor 23 is provided with a torque probe 21, and the microcontroller 24 is also electrically connected to an alarm 22. In this embodiment, the alarm 22 can be an audible and visual alarm.

[0045] Specifically, the torque sensor 23 is set up so that when the torque probe 21 is fully extended, it is subjected to force and twists, thereby triggering the torque sensor 23. The torque sensor 23 transmits a signal to the microcontroller 24, and the microcontroller 24 then controls the alarm 22 to sound an alarm, thereby reminding the inspection personnel that the cantilever has been extended to the preset position and the inspection work can be carried out. This avoids the cantilever sleeve being extended too much, which could cause damage to the swing arm structure or the inspection unit, thus ensuring the efficient operation of the inspection work.
