The purpose of this arrangement is to use the inner space of the fixing post 311, and at the same time, the fixing post 311 can protect the jack 91 to some extent. In other embodiments, the lifting column 312 may be disposed side by side with the fixed column 311.

Next, referring to fig. 6 to 8, in one embodiment, the second adjusting assembly 33 includes a fixed plate 331, a movable plate 332, a first trimming module 333 and a second trimming module 335, wherein the fixed plate 331 is fixedly connected to the driving chain 92 of the lifting driving assembly 9 through a bracket 313, the movable plate 332 is rotatably connected to the fixed plate 331 around a second axis Q, the first trimming module 333 is connected between the fixed plate 331 and the movable plate 332 for driving the movable plate 332 to rotate around the second axis Q, the second trimming module 335 is disposed on the movable plate 332 and is fixedly connected to the beam 7, and the second trimming module 335 is used for driving the beam 7 to rotate around a third axis M.

The rotation of the cross member 7 about the second axis Q is represented by the pitch of the cross member 7 as a whole, and the rotation of the cross member 7 about the third axis M is represented by the up-and-down swinging of the left and right sides of the cross member 7.

In the embodiment of the present application, the second adjusting component 33 is used to drive the beam 7 to rotate around the second axis Q and rotate around the third axis M, the two rotations are separated from the translation of the beam 7 in the first direction X and the second direction Y, and the beam 7 does not need to make the translational movement in the first direction X and the second direction Y on the second adjusting component 33, so that the rotation of the beam 7 is not affected, and the actions of the first trimming module 333 and the second trimming module 335 in the second adjusting component 33 are not affected.

In contrast, please refer to, assuming that the second adjusting assembly 33 is further capable of driving the beam 7 to translate in the first direction X, if the midpoint of the beam 7 in the first direction X is not aligned with the second adjusting assembly 33, when the beam 7 performs the pitch adjustment, the distance between the image capturing modules 72 at two ends of the beam body 71 and the vehicle to be inspected is different, and the captured images are different, so as to affect the detection result. Therefore, pitch adjustment can only be performed after ensuring that the cross beam 7 is adjusted in place in the first direction X.

Similarly, assuming that the second adjusting assembly 33 is also capable of driving the cross beam 7 to translate in the first direction X, if the midpoint of the cross beam 7 in the first direction X is not aligned with the second adjusting assembly 33, the distance between the image acquisition modules 72 at both ends of the cross beam body 71 and the vehicle to be inspected is different when the cross beam 7 swings up and down, which affects the detection result.

In the embodiment of the present application, the second fine adjustment module 335 is disposed on the movable plate 332 and is fixedly connected with the beam 7 to drive the beam 7 to rotate around the third axis M, so that the second fine adjustment module 335 can be fixedly connected with a midpoint of the beam 7 along the first direction X, so as to ensure that the left and right sides of the beam 7 are always symmetrical in the pitch adjustment process and the up-down swinging process. Such an arrangement can improve the adjustment efficiency. The left and right sides of the cross beam 7 remain symmetrical throughout the translation of the cross beam in the first direction X, in the second direction Y, in the third direction Z, and during rotation about the first axis P.

In addition, the structure of the second regulating member 33 can be simplified and the volume can be reduced.

Referring to fig. 6 to 8, the first fine adjustment module 333 includes a third screw rod 3333, a third nut 3334 and a connecting rod 3338, the third screw rod 3333 is rotatably mounted on the movable plate 332, the central axis of the third screw rod 3333 is perpendicular to the first direction X, the third nut 3334 is engaged with the third screw rod 3333, the first end of the connecting rod 3338 is rotatably mounted on the fixed plate 331 around the fourth axis N, the other end of the connecting rod 3338 is rotatably connected to the third nut 3334 around the fifth axis L, and the fifth axis L and the fourth axis N are parallel to the second axis Q.

When the third screw rod 3333 rotates, the third nut 3334 moves along the third screw rod 3333, and as shown in fig. 9, the movable plate 332 is pushed to rotate around the second axis Q to adapt to the length of the connecting rod 3338 because the third nut 3334 is rotatably connected with the other end of the connecting rod 3338. As shown in fig. 9, when the third nut 3334 slides up along the third screw rod 3333, an angle between the movable plate 332 and the fixed plate 331 becomes smaller.

Referring to fig. 7 and 8, in one embodiment, the first fine adjustment module 333 further includes a third guide rail 3336 and a third slider 3337, the third guide rail 3336 is fixedly disposed on the movable plate 332 and parallel to the central axis of the third screw rod 3333, the third slider 3337 is disposed on the third guide rail 3336, and the third slider 3337 is fixedly connected with the third nut 3334. When the third nut 3334 moves along the third screw rod 3333, the third slider 3337 is driven to move along the third guide rail 3336 synchronously. The other end of the link 3338 is rotatably coupled to the third slider 3337 about the fifth axis L.

Through the sliding configuration of the third guide rail 3336 and the third sliding block 3337, the third sliding block 3337 can limit the third nut 3334 to rotate around the third screw rod 3333, an additional circumference limiting structure is not required to be arranged for the third nut 3334, torque of the third screw rod 3333 is prevented from being transmitted to the connecting rod 3338 through the third nut 3334, the problems that the connecting rod 3338 deflects and is easy to be blocked are avoided, and smooth pitching adjustment of the movable plate 332 is ensured.

Further, by the arrangement of the third guide rail 3336 and the third slider 3337, the link 3338 may be disposed away from the third nut 3334 in the first direction X. This facilitates the arrangement of the structures within the first trimming module 333, and also allows the second adjusting assembly 33 to have a certain volume, so that a large enough connection area with the bracket 313, the beam body 71, etc. is facilitated, so as to ensure the connection stability between the second adjusting assembly 33 and the bracket 313, the beam body 71.

As shown in fig. 7 and 8, in one embodiment, the third guide rail 3336 and the third slider 3337 are configured to be two, and are respectively located at both sides of the third screw 3333 in the first direction X. The links 3338 may be configured in a group hinged to one of the third sliders 3337, or may be configured in two groups hinged to the third sliders 3337, respectively, as shown in fig. 8.

Thus, the two third sliding blocks 3337 slide on two sides of the third screw rod 3333 respectively, so that the forces of the third sliding blocks 3337 on two sides are balanced, and the sliding of the third sliding blocks 3337 is facilitated.

As shown in fig. 7 and 8, the two third sliders 3337 are fixedly connected by a connecting rod 3340. Of course, in the second direction Y, the connection rod 3340 is disposed to avoid the third screw 3333.

With continued reference to fig. 7 and 8, the first fine adjustment module 333 further includes a first bevel gear 3332 and a second bevel gear 3335 that are engaged with each other, wherein the first bevel gear 3332 is coaxially connected with one end of the third screw rod 3333, for example, is coaxially and fixedly connected with the upper end of the third screw rod 3333, the second bevel gear 3335 is rotatably mounted on the movable plate 332, and the central axis of the second bevel gear 3335 is perpendicular to the central axis of the first bevel gear 3332. By rotating the second bevel gear 3335, the rotation of the first bevel gear 3332 and the third lead screw 3333 can be achieved.

One end of the second bevel gear 3335 is connected to the first hand wheel 3331 by a first rotating lever 3341 for an operator to rotate the second bevel gear 3335. The purpose of this is to allow a worker to operate the rotation of the third screw 3333 from the left or right side of the second adjustment assembly 33. This is considered in that, as shown in fig. 1, the electric cabinet 82 is generally disposed above the second adjustment assembly 33, and thus, the rotation operation of the third screw 3333 may avoid the electric cabinet 82.

In other alternative embodiments, the first bevel gear 3332 and the second bevel gear 3335 may be omitted, and the first hand wheel 3331 may be provided directly at the upper end or the lower end of the third screw 3333, where the space above or below the second adjustment assembly 33 allows.

The second worm wheel 3353 is fixedly connected to the beam body 71 at a center point thereof in the first direction X.

The rotation of the second worm 3352 can be converted into the rotation of the second worm wheel 3353, thereby realizing the rotation of the cross beam 7 about the third axis M, which can adjust the heights of the left and right sides of the cross beam 7.

Referring to fig. 7 and 8, the second fine adjustment module 335 includes a third support plate 3356, the third support plate 3356 is fixedly disposed on a side surface of the movable plate 332 facing the fixed plate 331 (again, the third support plate 3356 is shown in a state of being separated from the movable plate 332), and the second worm 3352 passes through the third support plate 3356 and rotates in the third support plate 3356. In an alternative embodiment, a bearing (not shown) may be provided in the third support plate 3356 for supporting the second worm 3352.

Alternatively, the third support plate 3356 may be provided by a structure such that the third support plate 3356 simultaneously supports the third screw 3333, for example, supports the lower end of the third screw 3333.

In one embodiment, referring to fig. 7 and 8, the second worm 3352 is located between the third nut 3334 and a third slider 3337, and the second worm gear 3353 is located at one axial side, e.g., lower end, of the third screw 3333. The first trimming module 333 and the second trimming module 335 are arranged to cross each other and not to affect each other, and mutually use the space of each other, which makes the structural arrangement of the second adjusting assembly 33 more uniform.

In addition, in order to facilitate rotation of the third screw rod 3333, in one embodiment, as shown in fig. 7 and 8, the second fine adjustment module 335 further includes a third bevel gear 3354 and a fourth bevel gear 3355 engaged with each other, the third bevel gear 3354 is coaxially disposed at one axial end, such as an axial end, of the second worm 3352, the fourth bevel gear 3355 is rotatably mounted on the movable plate 332, and a central axis of the fourth bevel gear 3355 is perpendicular to a central axis of the third bevel gear 3354.
