[0015] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is the front view of the present invention; Figure 2 This is a three-dimensional schematic diagram of the present invention; Figure 3This is an assembly diagram of the basic boom 1, foot pedal 1, basic boom 2, foot pedal 2, gear plate, drive motor, mounting block, rotating rod, and gear in this utility model. The bridge inspection vehicle frame includes: a slewing platform 1 mounted on the vehicle, a main boom 2 connected and mounted on the slewing platform 1, and a vertical boom 3 connected and mounted to the other end of the main boom 2 via a connecting frame 4; The slewing platform 1 and the main boom 2 are connected by the same main boom luffing cylinder 5, and the main boom 2 and the connecting frame 4 are connected by the same connecting frame luffing cylinder 6. A basic boom 7 is provided on one side below the bottom end of the vertical boom 3. A foot pedal 10 is installed on the basic boom 7. Two slide rails 11 are installed on the top of the foot pedal 10. The two slide rails 11 are symmetrically distributed front and back. The same basic boom 12 is slidably mounted on both slide rails 11. The basic boom 12 is adapted to the basic boom 7. A foot pedal 13 is mounted on the basic boom 12.

[0016] A toothed plate 14 is installed at the bottom of the second basic boom 12. The toothed plate 14 is located between the two second basic booms 12, and there is a gap between the toothed plate 14 and the top of the second basic boom 12.

[0017] Two mounting blocks 16 are installed at the bottom of the basic boom 7. The two mounting blocks 16 are symmetrically distributed front and back. The same rotating rod 17 is rotatably mounted on the two mounting blocks 16. A gear 18 is fixedly sleeved on the rotating rod 17. A drive motor 15 is installed on the corresponding mounting block 16. The output shaft of the drive motor 15 is fixedly connected to one end of the rotating rod 17.

[0018] The bottom of the pedal 10 has an opening, through which the gear 18 passes and meshes with the toothed plate 14.

[0019] The basic boom 7 and the vertical boom 3 are both equipped with the same basic boom luffing cylinder 8 at their bottom ends, and a movable structure 9 is provided between the basic boom 7 and the vertical boom 3.

[0020] The movable structure 9 includes a fixed block and a concave block. The fixed block is installed on the basic boom 7, and the concave block is installed on the vertical boom 3. The fixed block and the concave block are rotatably connected.

[0021] The main boom luffing cylinder 5 can be an engineering cylinder of model HSGL01-200 / 125-1000, the connecting frame luffing cylinder 6 can be a cylinder of model HSGL01-160 / 100-800, and the basic boom luffing cylinder 8 can be a cylinder of model HSGL01-125 / 80-600.

[0022] The drive motor 15 can be a three-phase asynchronous motor of model Y100L1-4. This motor has high starting torque and stable operating performance, and can provide sufficient power for the rotation of gear 18 to drive the basic boom 12 to slide smoothly on the slide rail 11.

[0023] The working principle of the bridge inspection vehicle frame provided by this utility model is as follows: The first step: Based on the vehicle, drive it to the bridge location to be inspected. The slewing platform 1 starts working on the vehicle. It can rotate at a certain angle through the slewing mechanism (the slewing platform is a pre-existing technology structure, so its structural principle will not be elaborated here). Adjust the direction of the main boom 2 so that it is aligned with the part of the bridge to be inspected. The main boom luffing cylinder 5 starts to move. Through the extension and retraction of the piston rod, it pushes the main boom 2 to swing up and down around its connection point with the slewing platform 1, changing the elevation angle of the main boom 2, thereby adjusting the working height and position. The second step: After the main boom 2 is adjusted to the appropriate position, the connecting frame luffing cylinder 6 works. The piston rod of the connecting frame luffing cylinder 6 extends and retracts, driving the connecting frame 4 to rotate around its connection point with the main boom 2, thereby adjusting the angle and position of the vertical boom 3, so that the vertical boom 3 is closer to the bottom of the bridge or other locations that need to be inspected. The third step: The basic boom luffing cylinder 8 between the basic boom 7 and the vertical boom 3 is activated. According to the actual testing requirements, the angle between the basic boom 7 and the vertical boom 3 is adjusted by the extension and retraction of the piston rod, further fine-tuning the working position. At the same time, if it is necessary to adjust the position of the basic boom 12, the drive motor 15 is started, and its output shaft drives the rotating rod 17 to rotate. The gear 18 on the rotating rod 17 rotates accordingly. Since the gear 18 meshes with the toothed plate 14, and the toothed plate 14 is installed at the bottom of the basic boom 12, the basic boom 12 slides along the slide rail 11 under the drive of the gear 18, realizing the position adjustment and providing a more suitable working platform for the testing personnel.
