Wherein the position adjusting device 2 can be arranged on the supporting platform 100.

Wherein, the position adjusting device 2 comprises a rotating device 21 and a lifting device 22 arranged on the rotating device 21. The accelerator body 1 is connected with the lifting device 22, and the rotating device 21 is connected with the supporting platform 100. In one aspect the support platform 100 is a vehicle.

The rotating device 21 includes a rotating member 211 and a rotating platform 212 connected to the rotating member 211, and the lifting device 22 is connected to the rotating platform 212 and can rotate together with the rotating platform 212. Wherein the rotary platform 212 is rotatable between a first position and a second position. And, the supporting platform has a first edge 101, when the rotating platform 212 is at the second position, the projection of the accelerator body 1 on the surface of the supporting platform 100 is located outside the first edge 101 of the supporting platform 100, and the projection of the rotating platform 212 on the surface of the supporting platform 100 is located inside the first edge 101 of the supporting platform 100.

In one aspect, when the rotating platform 212 is in the first position, the projection of the accelerator body 1 on the surface of the support platform 100 is at least partially located within the first edge 101 of the support platform 100. Preferably, when the rotating platform 212 is in the first position, the projection of the accelerator body 1 on the surface of the supporting platform 100 is entirely located within the first edge 101 of the supporting platform 100. When the supporting platform 100 is a vehicle, the first edge 101 is a rear edge of the vehicle body in a longitudinal direction.

By adopting the scheme of the application, the accelerator body 1 can be switched between the inside and the outside of the supporting platform 100 under the action of the rotating device 21 and the lifting device 22, and the accelerator body 1 can be positioned in the inside of the supporting platform 100 in the transportation process, so that the transportation is convenient and the length of the platform is reduced. During operation, the accelerator body 1 can be positioned outside the supporting platform 100, so that the accelerator body 1 can be conveniently adapted to working positions with different heights.

In one aspect, when the rotating platform 212 is in the second position, the projection of the accelerator body 1 on the surface of the support platform 100 is adjacent to the edge of the support platform 100. For example, the distance between the projection of the accelerator body 1 on the surface of the support platform 100 and the edge of the support platform 100 is 5-20 cm.

By adopting the scheme, the accelerator body 1 is arranged close to the edge of the supporting platform 100 in the second position, so that the size of the whole equipment is ensured not to be too large in work.

In one aspect, as shown in fig. 4-5, the rotating device 21 further includes a rotating fitting 213, and the rotating element 211 can rotate relative to the rotating fitting 213. Wherein the rotation fitting 213 is disposed on the support platform 100. In one aspect, the rotating device 21 further includes a rotating driving element 214 for driving the rotating element 211 to rotate relatively with respect to the rotating fitting element 213. The rotary driving member 214 may be an electric motor or a hydraulic motor, and a reduction gear and a gear, etc. are provided. In one aspect, the rotating member 211 is a unitary structure with the rotating platform 212.

In one aspect, the rotary drive 214 may be disposed inside or outside the rotary platform 212 (not shown).

In one aspect, as shown in fig. 4, the rotating element 211 has a ring-shaped structure, and the rotating fitting element 213 has a receiving space, such that the rotating element 211 can be placed in the receiving space of the rotating fitting element 213; the inner surface of the ring structure has teeth for mating with the gear of the rotary drive 214; the outer surface of the annular structure of the rotating member 211 and the inner surface of the accommodating space of the rotating fitting member 213 are both smooth structures, so that the outer surface of the annular structure of the rotating member 211 and the inner surface of the accommodating space of the rotating fitting member 213 can relatively rotate and slide. In one aspect, rolling elements (e.g., balls or rolling cones) are provided between the outer surface of the annular structure of the rotating element 211 and the inner surface of the receiving space of the rotation fitting 213. Thus, under the driving of the rotary driving member 214, the rotary member 211 can rotate relative to the outer rotary mating member 213, and the rotary platform 212 can be driven to rotate.

In one aspect, as shown in fig. 5, the rotating element 211 is a ring structure, the rotating fitting element 213 has a shaft structure, the inner surface of the ring structure of the rotating element 211 and the shaft surface of the rotating fitting element 213 are both smooth structures, and the rotating element 211 is sleeved outside the shaft of the rotating fitting element 213 and can rotate relatively. The outer surface of the ring-shaped structure has a tooth structure for cooperating with the gear of the rotary drive member 214. In one aspect, rolling elements (e.g., balls or rolling cones) are provided between the inner surface of the annular structure of the rotating element 211 and the outer surface of the shaft of the rotating fitting 213. Thus, under the driving of the rotary driving member 214, the first rotary member 211 can rotate relative to the rotary mating member 213, and the rotary platform 212 can be driven to rotate. Thus, under the driving of the rotary driving member 214, the first rotary member 211 can rotate relative to the inner rotary mating member 213, and the rotary platform 212 can be rotated.

As shown in fig. 6 to 7, in one aspect, the lifting device 22 includes a slider 221, a lifting rail 222, and a lifting driving device 223. Wherein, under the action of the lifting driving device, the sliding part 221 and the lifting guide rail 222 can generate relative displacement.

Wherein one of the slide member 221 and the lift rail 222 is connected to the rotary platform 212 and the accelerator body 1, respectively. In this way, the relative movement of the accelerator body 1 with respect to the rotary platform 212 can be achieved, and the operating position of the accelerator body 1 can be adjusted.

In one embodiment, the lifting driving device 223 is a cylinder, a gear, a chain wheel, or the like, which can control the accelerator body 1 to stop at any position.

Specifically, the elevating driving means 223 includes a fixed end connected to the rotating platform 212 and a telescopic end connected to the sliding member 221, which is telescopic with respect to the fixed end.

In one aspect, the lift rail 222 is a U-shaped structure having a bottom wall and a first side wall and a second side wall connected to two sides of the bottom wall. The slider 221 slides in an enclosed space formed by the bottom wall and the two side walls. In one aspect, the bottom wall is connected to the rotating platform 221.

In one aspect, a bearing 224 is disposed on the bottom wall and at least one first sidewall of the lifting rail 222, and a groove 225 for receiving the bearing 224 is disposed on the slider 221. The groove 225 has a U-shaped cross section, and both side walls of the groove 225 are engaged with the surface of the bearing 224. Through the cooperation of the bearing 224 and the groove 225, the bearing 224 can limit the movement of the bearing 224 perpendicular to the lifting movement direction while the groove 225 performs the lifting movement, so as to limit the movement of the sliding member 221 perpendicular to the lifting movement direction (when the lifting movement is a vertical direction, the movement in a horizontal direction is limited). In one aspect, a bearing 224 is disposed on each of the first and second sidewalls, and a groove 225 is correspondingly formed on the surface of the sliding member 221 at a position corresponding to the bearing 224. In one aspect the number of bearings on each of the side and bottom walls may be two or more.

With this arrangement, the cooperation of the bearing 224 and the groove 225 ensures that the sliding member 221 can move linearly along the lifting rail, and provides a reaction force against the force applied to the connection point between the sliding member 221 and the lifting rail 222 by the gravity of the accelerator body 1, thereby preventing the sliding member 221 from being detached from the rail and causing damage to the apparatus.

In one aspect, the positions of the bearing 224 and the groove 225 may be reversed, that is, the bearing 224 is disposed on the slider 221 and the groove 225 is formed on the lifting rail 223.

As shown in fig. 7 and 8, in one aspect, an adjusting mechanism 23 is further disposed between the rotating platform 212 and the lifting device 22, and is configured to adjust a positional relationship, including a distance angle, between the lifting device 22 and the rotating platform 212.

In one embodiment, the adjusting mechanism 23 includes three adjusting units 231, the three adjusting units 231 are arranged in a triangle, each adjusting unit 231 is a length-adjustable device, and one end of each adjusting unit 231 is connected to the rotating platform 212, and the other end of each adjusting unit 231 is connected to the lifting device 22 (one of the sliding member 221 or the lifting guide 222). By adjusting the amount of extension and retraction of the three adjustment units, the distance, tilt angle, pitch angle, or the like of the lifting device 22 with respect to the rotating platform 212 can be adjusted.

For example, when the three adjusting units 231 are extended and contracted by the same length, the lifting device 22 is integrally translated with respect to the rotating platform 212, so that the distance between the two can be adjusted. Thus, during operation, the position relationship of the accelerator body 1 relative to the first edge 101 can be correspondingly adjusted, and interference or overlarge distance is avoided.

When the length of one or two of the adjusting units 231 is adjusted, the lifting device 22 is correspondingly deflected, so that the lifting device is tilted or pitched, and the angle of the accelerator body 1 relative to the support platform 100 can be adjusted. And then can conveniently adapt to the scanned object and the actual situation of the detection device, avoid the loss of rays and improve the detection precision.

In one aspect, both ends of at least one of the adjusting units 231 are connected with the rotating platform 212 and the lifting device 22 in a hinged manner. By adopting the scheme, when the inclination angle or the pitching angle of the accelerator body is adjusted, the adjusting range is wider, the adjustment is more flexible and reliable, and the interference possibly generated between the two is avoided.

In one embodiment, four adjusting units 231 are included, and the four adjusting units 231 are arranged in a rectangular shape. By the scheme, the angle can be adjusted more conveniently.

In one embodiment, the adjusting unit 231 is a combined structure of a bolt and a nut, and in another embodiment, the adjusting unit is a nut screw structure or an air cylinder or an oil cylinder.

The application also provides a vehicle-mounted radiation imaging device, which comprises a vehicle and the accelerator, wherein the accelerator body 1 is connected with the vehicle through the lifting device 22 and the rotating device 21.

In one aspect, when the rotating platform 212 is located at the second position, a supporting device is disposed below the rotating platform for supporting the rotating platform at a position outside the rotating member 211 to share the force received by the rotating member 211. Wherein, the contact surface of the supporting device and the rotating platform 212 is a smooth structure. In another aspect, rolling members are provided between the support device and the rotating platform 212. In another aspect, a support device is also disposed below the rotating platform 212 when it is in the first position.

The position adjusting device 2 includes a rotating device 21, a lifting device 22, and an adjusting mechanism 23 disposed therebetween.

The rotating means 21 comprises a rotating member 211, a rotating platform 212 connected to the rotating member 211, a rotating fitting 213 and a rotating drive 214. Under the action of the rotary drive 214, the rotary platform 212 can rotate relative to the rotary fitting 213 along with the rotary element 211. The rotary driving member 214 is a motor and a reduction gear and a gear.

Wherein the rotation fitting 213 is provided on the vehicle 100, which has an accommodation space. The rotating member 211 has a ring-shaped structure, and the rotating member 211 can be placed in the receiving space of the rotating fitting member 213. Wherein the inner surface of the ring-shaped structure of the rotary member 211 has teeth for cooperating with the gear of the rotary drive member 214; the outer surface of the annular structure of the rotating member 211 and the inner surface of the accommodating space of the rotating fitting member 213 are both smooth structures, so that the outer surface of the annular structure of the rotating member 211 and the inner surface of the accommodating space of the rotating fitting member 213 can relatively rotate and slide.

The lifting device includes a slider 221, a lifting rail 222, and a lifting driving device 223. Under the action of the lifting driving device, the sliding member 221 and the lifting guide rail 222 can be relatively displaced. The sliding member 221 is fixedly connected to the accelerator body 1, and the lifting rail 222 is connected to the rotary platform 212 through the adjusting mechanism 23.

The lifting rail 222 is a structure with a U-shaped cross section, and includes a bottom wall, and a first side wall and a second side wall connected to two sides of the bottom wall. The slider 221 is slidable in the enclosed space formed by the bottom wall and the two side walls.

Bearings 224 are provided on the bottom wall, the first side wall and the second side wall of the elevating guide 222, respectively, and a groove 225 for accommodating the bearings 224 is provided on the slider 221. Wherein, the cross section of the groove 225 is U-shaped, and two side walls of the groove 225 are matched with the surface of the bearing 224. Through the matching of the bearing 224 and the groove 225, the bearing 224 can limit the movement of the bearing 224 in the direction perpendicular to the lifting movement direction while the groove 225 performs lifting movement, and further limit the movement of the sliding piece 221 in the direction perpendicular to the lifting movement direction

The adjusting mechanism 23 includes four adjusting units, each of which is a length-adjustable device, one end of which is hinged to the rotating platform 212, and the other end of which is hinged to the lifting rail 222. By adjusting the amount of expansion and contraction of the four adjustment units, the distance, tilt angle, pitch angle, or the like of the lifting device 22 with respect to the rotating platform 212 can be adjusted.

The working process of the scheme of the embodiment 1 of the application is described below by combining the accompanying drawings:

as shown in fig. 1 to 3, in a non-operating state (e.g., a transport state), the rotary platform 212 is located at a first position, and the accelerator body 1 is on the vehicle.

When the operation state needs to be adjusted, the rotation driving device 214 operates to rotate the rotating member 212 relative to the rotating fitting member 213, so as to drive the rotating platform 212 to rotate a certain angle (for example, 90 degrees) to a second operation position, at this time, the rotating platform 212 is located inside the first edge 101 of the vehicle, and the accelerator body 1 rotates along with the rotating platform to be located outside the first edge 101 of the vehicle, as shown in fig. 10-12

The lifting drive device 223 starts to move, so that the sliding member 221 moves relative to the guide rail 222, and the accelerator body 1 is driven to move downwards, and gradually reaches the working position, as shown in fig. 13-14.

When the distance and/or the inclination angle of the accelerator body 1 relative to the rotating platform 212 needs to be adjusted, at least one of the adjusting units 231 is controlled according to the situation, so that the guide rail 222 acts to drive the accelerator body 1 to reach the required position.

When the operation is completed and the accelerator body 1 needs to be adjusted from the operating state to the non-operating state, first, the lifting drive device 223 starts to operate, so that the sliding member 221 moves relative to the guide rail 222, and drives the accelerator body 1 to move upward, so that the bottom surface of the accelerator body 1 reaches the upper side of the vehicle.

The rotary driving device 214 is then operated to rotate the rotary member 212 relative to the rotary mating member 213, so as to rotate the rotary platform 212 by a certain angle (e.g. 90 degrees) to reach the first working position.
