DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0047] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0048] refer to Figures 1 to 10 As shown, the inspection system of the embodiment of the present invention includes a door-shaped frame for forming an inspection channel, and the door-shaped frame includes a cabin 1 for installing a radiation source and two vertical support arms 2 respectively arranged on both sides of the cabin 1 and supporting the cabin 1, and the vertical support arms 2 are telescopically arranged so that the height of the cabin 1 can be changed. When the inspection system needs to be transferred and transported, the vertical support arms 2 are controlled to retract so as to reduce the overall height of the inspection system to meet the transportation height requirements; after arriving at the work site, the vertical support arms 2 are controlled to extend so that the height of the inspection channel meets the requirements of the inspection operation, so the inspection system of the embodiment of the present invention can better meet the transfer and transportation requirements. Moreover, when the inspection system of the embodiment of the present invention is used as a vehicle inspection system to inspect vehicles, since the height differences of various vehicles are large, the height of the cabin can be adjusted according to the height of the actual vehicle to be inspected, thereby expanding the applicability range of the inspection system of the embodiment of the present invention.

[0049] According to the following Figures 1 to 10 The specific structure and working process of the inspection system of a specific embodiment of the present invention are described in detail.

[0050] The inspection system of this embodiment is a vehicle inspection system, but each structure of the inspection system of this embodiment can be applied to inspection systems for inspecting various other objects.

[0051] It should be noted that in the following description, "front" refers to the position of the vehicle relative to the inspection system when it has not entered the inspection channel, "rear" refers to the side opposite to "front", and "left" and "right" refer to the left and right directions formed when facing the front.

[0052] like Figure 1As shown, the vehicle inspection system of this embodiment includes a cabin 1 for installing a radiation source and two vertical support arms 2 for supporting the cabin 1. The two vertical support arms 2 and the cabin 1 form a door-shaped frame. The door-shaped frame forms an inspection channel. The two vertical support arms 2 are telescopically arranged. Figure 1 and Figure 2 The vertical support arm 2 is shown in a retracted state. Figure 3 The vertical support arm 2 is shown in an extended state.

[0053] Specifically, the inspection system of this embodiment is 3.45m high when in working state, and the inspection channel is 2.5m high at this time, which can meet the requirements of detecting various vehicles. The inspection system of this embodiment is 2.35m high when in transport state, which can meet the height requirements of transport.

[0054] Preferably, if Figure 3 As shown, the vertical support arm 2 includes a first segment 21 and a second segment 22 arranged in the vertical direction, the cabin 1 is arranged on the second segment 22, and the second segment 22 is movably arranged relative to the first segment 21. The second segment 22 moves downward relative to the first segment 21 to retract the vertical support arm 2, and the second segment 22 moves upward relative to the first segment 21 to extend the vertical support arm 2.

[0055] Specifically in this embodiment, the first segment 21 is sleeved on the outer side of the second segment 22 .

[0056] Preferably, if Figure 5 As shown, a first guide structure 23 is provided on the first segment 21, and a second guide structure 24 is provided on the second segment 22. The first guide structure 23 and the second guide structure 24 are slidably matched. The second segment 22 moves relative to the first segment 21 through the slidable match between the first guide structure 23 and the second guide structure 24, so that the second segment 22 moves along a certain path, thereby improving the stability of the extension and retraction of the vertical support arm 2. Moreover, the slidable match between the first guide structure 23 and the second guide structure 24 can reduce the friction between the two, thereby reducing wear and extending the service life.

[0057] Specifically in this embodiment, the first guide structure 23 includes a first guide block extending in the vertical direction. The second guide structure 24 includes a second guide block extending in the vertical direction. A vertical convex strip is provided on one of the mating surface of the first guide block that cooperates with the second guide block and the mating surface of the second guide block that cooperates with the first guide block. The first guide block and the second guide block achieve sliding fit through the fit between the vertical convex strip and the mating surface, thereby reducing the contact area between the first guide block and the second guide block, further reducing friction and thus reducing wear.

[0058] Specifically, in this embodiment, the first segment 21 and the second segment 22 are both square structures. Corresponding guide blocks are arranged on the four sides of the first segment 21 and the second segment 22, so as to ensure the stability of the movement of the second segment 22 relative to the first segment 21.

[0059] Of course, in other embodiments not shown in the drawings, the first segment and the second segment may also be in other shapes, such as a columnar shape, a polyhedral structure, etc.

[0060] In this embodiment, the inspection system further includes a hydraulic cylinder for driving the second segment 22 to move relative to the first segment 21 .

[0061] In order to lock the second segment 22 at the set position and fix the cabin 1 at a certain position when the second segment 22 reaches the set position, the inspection system of this embodiment also includes a position locking device, which is used to limit the movement of the second segment 22 after the second segment 22 reaches the set position.

[0062] Specifically in this embodiment, Figure 5 As shown, the position locking device includes a locking screw 25. The locking screw 25 is screwed on the first segment 21 and when the locking screw 25 is in a tightened state, the end of the locking screw 25 abuts against the second segment 22. When it is necessary to control the movement of the second segment 22, the locking screw 25 is rotated to make its end away from the second segment 22 to complete the unlocking, and the second segment 22 is separated from the abutment of the locking screw 25 so that it can move under the drive of the hydraulic cylinder. When the second segment 22 reaches the specified position, the locking screw 25 is rotated to make its end move in a direction close to the second segment 22 to abut against the second segment to prevent the second segment from swinging.

[0063] Preferably, the position locking device of this embodiment further includes a protrusion disposed on the second segment 22 and disposed corresponding to the position of the locking screw 25. The protrusion may be made of a material with a large friction coefficient. Alternatively, the end surface of the protrusion that abuts against the locking screw 25 may be made of a material with a large friction coefficient. Such an arrangement may increase the friction force when the locking screw 25 abuts against the second segment 22, prevent disengagement, and ensure the reliability of the position locking device.

[0064] Preferably, the inspection system of this embodiment further includes a position feedback device. The position feedback device sends an in-position signal when the second segment 22 reaches the set position. When the second segment 22 reaches the set position, the in-position signal is sent. After receiving the in-position signal, the staff rotates the locking screw to make the locking screw abut against the second segment. At this time, the locking screw and the second segment are in a tight fit state, and no further adjustment is required by the staff.

[0065] Preferably, the position feedback device and the position locking device can also be coupled and arranged. After the second segment 22 reaches the set position, an arrival signal is sent, and the position locking device receives the arrival signal and automatically performs a position locking action, thereby realizing automatic control.

[0066] Specifically, Figure 4 As shown, the position locking device of this embodiment includes an upward travel switch 15, a downward travel switch 16, an upward positioning screw (not shown in the figure) and a downward positioning screw 17. When the vertical support arm 2 is extended, after the upward travel switch 15 receives the feedback signal of the upward positioning screw, the upward travel switch 15 sends an electrical signal to the oil pump used to supply oil to the hydraulic cylinder. After receiving the electrical signal, the oil pump stops supplying oil to the hydraulic cylinder and the locking screw locks the second segment to prevent the second segment from swinging. When the vertical support arm 2 is retracted, after the downward travel switch 16 receives the feedback signal of the downward positioning screw 17, it sends an electrical signal to the oil pump, the oil pump stops working, and the inspection system can be transferred.

[0067] Preferably, in order to ensure that the telescopic movement of the left and right vertical support arms can be synchronized, the movement control of the left and right vertical support arms in this embodiment is controlled according to the following strategy: only when both the rising travel switch on the left vertical support arm and the rising travel switch on the right vertical support arm are triggered, the two hydraulic cylinders used to control the movement of the two vertical support arms respectively stop supplying oil at the same time. In other words, if only one of the two rising travel switches is triggered, the oil pumps used to supply oil to the two hydraulic cylinders work normally. The control strategy when the vertical support arm is lowered is the same as above and will not be repeated here.

[0068] like Figure 1 As shown, the inspection system of this embodiment further includes a cross arm 5 disposed between the two support seats 3. A detector is installed in the cross arm 5. The cross arm 5 is disposed opposite to the cabin 1 and is installed with a detector for receiving radiation, thereby obtaining a perspective image of the interior of the vehicle.

[0069] In order to prevent the inspection system from shaking, ensure the position stability of the inspection system and improve the imaging performance of the inspection system, such as Figure 1 , Figure 2 and Figure 7 As shown, the inspection system of this embodiment further includes two support seats 3 respectively arranged below the two vertical support arms 2. The lower ends of the vertical support arms 2 are located in the middle of the support surface of the support seats 3. The boundary lines of the support surface of the support seats 3 all exceed the boundary lines of the lower ends of the vertical support arms 2. The arrangement of the support seats 3 increases the ground contact area of ​​the inspection system, thereby facilitating the stability of the inspection system.

[0070] Preferably, in order to further increase the grounding area of ​​the inspection system, the support base 3 of this embodiment includes a support base body 31 and an auxiliary support body 32 arranged at the end of the support base body 31 in the length direction. The auxiliary support body 32 is foldably arranged relative to the support base body 31. The auxiliary support body 32 is foldably arranged relative to the support base body 31. When the inspection system is in working state, Figure 7 As shown, the auxiliary support body 32 is unfolded to the front and rear ends of the support base body 31; when the inspection system is in the transfer transportation state, as shown Figure 1 and Figure 2 As shown, the auxiliary support body 32 is folded to the inner side of the support base body 31 so as to reduce the length of the entire inspection system in the front-to-back direction for easy transportation.

[0071] In other embodiments not shown in the drawings, the auxiliary support body 32 may also be retractably arranged relative to the support seat body 31, for example, the auxiliary support body 32 may be movably arranged inside the support seat body 31. When a transfer is required, the auxiliary support body 32 moves toward the inside of the support seat body 31 to reduce the length of the inspection system in the front-to-back direction; when the transfer to the work site requires entering the working state, the auxiliary support body 32 moves toward the outside of the support seat body 31 to increase the ground contact area of ​​the inspection system.

[0072] In order to improve the grounding stability of the inspection system, the inspection system of this embodiment further includes three main support plates 4 arranged at the lower sides of the two support seats 3. One of the three main support plates 4 is arranged below one of the two support seats 3, and the other two of the three main support plates 4 are arranged below the other of the two support seats. The three main support plates 4 form a plane so that the inspection system is in a plane so that the inspection system can be in a plane at different work sites, thereby ensuring the stability of the inspection system.

[0073] Since the three support plates are on the same plane, the inspection system may tilt and swing when a vehicle passes by. In order to prevent the above phenomenon from occurring and thus ensure the safety of the inspection system, the inspection system of this embodiment further includes an auxiliary support plate 8 disposed below the auxiliary support body 32. When the inspection system tilts due to the passage of a vehicle, the auxiliary support plate 8 plays an auxiliary fixing role for the inspection system, thereby improving the anti-overturning performance of the inspection system.

[0074] In order to ensure that the vehicle enters or exits the inspection channel smoothly, a clearer and more stable perspective image can be obtained. Figure 1 As shown, the inspection system of this embodiment further includes a support ramp 6 disposed between the two support seats 3 , and the cross arm 5 is fixedly disposed relative to the support ramp 6 .

[0075] Specifically, the cross arm 5 of this embodiment is fixedly connected to the supporting ramp 6 by means of positioning pins and bolts.

[0076] Preferably, if Figure 1 As shown, the inspection system of this embodiment also includes an auxiliary ramp 7 arranged on the supporting ramp 6. The auxiliary ramp 7 includes a first auxiliary ramp and a second auxiliary ramp located on the left and right sides respectively. The setting of the auxiliary ramp allows the vehicle to be inspected to pass directly, thereby realizing a quick inspection. The first auxiliary ramp and the second auxiliary ramp correspond to the positions of the left and right wheels of the vehicle to be inspected, respectively. Compared with the prior art that requires laying the auxiliary ramp on the entire width in the left and right directions, the weight of the inspection system can be reduced, which is convenient for transfer.

[0077] In order to facilitate the transition, the auxiliary ramp 7 of this embodiment is foldably arranged relative to the supporting ramp 6. Figure 1 The auxiliary ramp 7 is shown in a state where it is folded inward.

[0078] In other embodiments not shown in the drawings, the auxiliary ramp 7 can be telescopically arranged relative to the supporting ramp 6, which can also reduce the transition volume of the inspection system.

[0079] In order to conduct a comprehensive inspection of the inspected vehicle, the inspection system of this embodiment further includes a vertical detection arm 11 disposed on the side of the vertical support arm 2. A detector is mounted on the vertical detection arm 11. The detector on the vertical detection arm 11 receives the radiation from the radiation source to inspect the interior of the vehicle.

[0080] Since the inspection system needs to be installed on site after the transfer, and during the installation and adjustment of the inspection system, the position of the vertical detection arm 11 also needs to be adjusted.

[0081] In order to adjust the position of the vertical detection arm 11, the inspection system of this embodiment further includes a position adjustment mechanism for adjusting the position of the vertical detection arm 11. The position adjustment mechanism is used to adjust the angle of the vertical detection arm and also to adjust the position of the vertical detection arm in the front-to-back direction and in the left-to-right direction.

[0082] Preferably, the position adjustment mechanism includes a connecting seat for connecting the vertical detection arm 11 and the vertical support arm 2, the connecting seat includes a first connecting portion for connecting to the vertical detection arm 11 and a second connecting portion for connecting to the vertical support arm 2, and the fixed position between the vertical detection arm 11 and the first connecting portion can be set variably; the fixed position between the vertical support arm 2 and the second connecting portion can be set variably.

[0083] Specifically in this embodiment, Fig. 9 and Fig.10As shown, the connection seat of this embodiment includes an L-shaped connection seat. The L-shaped connection seat includes a first seat body P and a second seat body Q arranged perpendicularly to each other. The first seat body P forms a first connection portion. The second seat body Q forms a second connection portion. The fixed position between the first seat body P and the vertical detection arm 11 can be variably set to adjust the position and angle of the vertical detection arm 11 in the front-rear direction.

[0084] Specifically, a first long hole is provided on one of the first base body and the vertical detection arm 11, and a first connecting member is provided on the other of the first base body and the vertical detection arm 11, and the first connecting member is inserted into the first long hole. The length direction of the first long hole is arranged along the front-to-back direction. For example, the first long hole is provided on the first base body, and the first connecting member is provided on the vertical detection arm 11. Since the first connecting member can move in the first long hole, space is left for the front-to-back movement of the vertical detection arm 11. Moreover, when the angle of the vertical detection arm 11 needs to be adjusted, the vertical detection arm can also be controlled to rotate around the connection between the first connecting member and the first long hole.

[0085] Specifically in this embodiment, the inspection system includes two connection sockets arranged along the vertical direction, namely a first connection socket 13 and a second connection socket 14 .

[0086] In order to achieve the left-right position adjustment of the vertical detection arm, Fig. 9 and Fig.10 As shown, the fixing positions of the second seat body Q and the vertical support arm 2 of this embodiment are adjustable. Specifically, the fixing positions of the second seat body Q and the first segment 21 are adjustable.

[0087] Specifically, a second long hole is provided on one of the second seat body Q and the first segment 21, and a second connecting member is provided on the other of the second seat body Q and the first segment 21. The second connecting member is inserted into the second long hole, and the second long hole is provided along the left-right direction. For example, the second seat body Q is provided with a second long hole, and the vertical detection arm 11 is provided with a second connecting member. Since the second connecting member moves in the second long hole, space is left for adjusting the position of the vertical detection arm 11 in the left-right direction.

[0088] In this embodiment, the length directions of the first long hole and the second long hole are perpendicular to each other. However, in other embodiments not shown in the drawings, the length directions of the first long hole and the second long hole may also be arranged at other angles, as long as the position adjustment of the vertical detection arm in the front-back and left-right directions can be achieved. Of course, in this embodiment, the length direction of the first long hole is set to the front-back direction, and the length direction of the second long hole is set to the left-right direction, which is more convenient for position adjustment.

[0089] After adjusting the position of the vertical detection arm 11, it is also necessary to locate the position of the vertical detection arm 11. Therefore, the position adjustment mechanism of this embodiment also includes a first limiting structure for limiting the position of the vertical detection arm 11 relative to the first seat body P. The first limiting structure includes a first abutting seat provided on the vertical detection arm 11 and a first adjustment column and a second adjustment column respectively abutting against the first abutting seat on both sides along the length direction of the first long hole. The first adjustment column and the second adjustment column are movably arranged on the first seat body P along the length direction of the first long hole. Before adjusting the position of the vertical detection arm, the first adjustment column and the second adjustment column respectively abut against the two sides of the first abutting seat, so the position of the vertical detection arm is fixed. When the position of the vertical detection arm is to be adjusted, the first adjustment column or the second adjustment column is rotated to make it away from the corresponding side of the first abutting seat, and then the vertical detection arm is controlled to move a set distance. After reaching the position, the first adjustment column and the second adjustment column are rotated to make them abut against the corresponding side of the first abutting seat to complete the positioning.

[0090] Preferably, in order to fix the first adjustment column and the second adjustment column within the moving range, the position adjustment mechanism of this embodiment further includes a fixing portion for fixing the first adjustment column and / or the second adjustment column. In this embodiment, the first adjustment column and the second adjustment column are studs, and the fixing portion can be a nut.
