The support platform and its application according to embodiments of the present disclosure will be described in detail below with reference to fig. 1 to 5 by taking a radiation inspection device as an example.
Fig. 1-2 illustrate a support platform of an embodiment of the present disclosure. Fig. 3 to 5 show a radiation inspection device employing the support platform shown in fig. 1 to 2.
As shown in fig. 3 to 5, the radiation inspection device includes a fixed gantry 1, a movable gantry 2, a scanning apparatus 3, and a support platform. The support platform comprises a bottom platform 4, a sensor 6 and a controller 7.
The fixed frame 1 comprises a fixed frame body 11 and a track 12 arranged on the top of the fixed frame body 11. The movable frame 2 comprises a movable frame body 21 and a traveling device 22 arranged on the movable frame body 21. The movable frame 2 is configured to be carried on the fixed frame 1 by a running gear 22 and to be capable of reciprocating along the rail 12. The scanning device 3 comprises a radiation source 31 and a detector 32, the radiation source 31 and the detector 32 being arranged on the movable housing body 21. The bottom platform 4 is located at the bottom of the stationary gantry body 11 and includes a platform top plate 41 for carrying an object under inspection. The fixed gantry body 11, the movable gantry body 21, and the table top 41 form a scan path P of the radiation inspection device.
When the radiation inspection device inspects an inspected object, such as a vehicle, the traveling device 22 drives the movable rack body 21 to travel along the track 12, so that the scanning device 3 on the movable rack body 21 is carried to synchronously move along with the movable rack 2. Since the track 12 is disposed on the fixed frame 1, instead of walking on the ground or the track disposed on the ground, the walking device 22 can walk on the track 12 stably only by firmly disposing the fixed frame 1 on the ground, and is less affected by the flatness of the ground, so that the movable frame 2 and the scanning device 3 thereon can move stably relative to the fixed frame 1. It is advantageous to ensure that the acquired image does not suffer from quality degradation due to jitter generated by the scanning device 3. On the other hand, it is also advantageous to reduce or eliminate the costs of civil engineering. Because the scanning device 3 moves reciprocally along with the travelling device 22 and the detected object can be placed on the bottom platform 4 to stand still for scanning inspection, the length of the fixed frame 1 is only longer than that of a single detected object, and compared with the setting mode of the scanning device 3 for fixing the detected object, the size and weight of the radiation inspection equipment can be reduced.
As shown in fig. 3 and 4, in some embodiments, running gear 22 includes a plurality of running wheels 221 and a running drive 222. The plurality of road wheels 221 include a drive wheel drivingly connected to a road drive 222. The travel drive device 222 is, for example, a rotary motor. A transmission, which may include, for example, a speed reducer, may also be provided between the travel drive 22 and the drive wheels. For smooth running of the running gear 22, the running gear may further include guide wheels or the like fitted to the sides of the rail.
As shown in fig. 3, the rail 12 is disposed in the left-right direction in the drawing (the front-rear direction in fig. 4 and 5), and the scanning path P formed by the fixed frame body 11, the movable frame body 21, and the platform top 41 is also disposed in the left-right direction in fig. 3 (the front-rear direction in fig. 4 and 5).
The fixing support is of a frame structure, and can comprise a top cross beam, a top longitudinal beam, a bottom cross beam, a bottom longitudinal beam and a plurality of upright posts. In order to make the frame structure firmer, the top, bottom and transverse sides can be provided with middle longitudinal beams, oblique beams and other structures, and reinforcing structures such as reinforcing plates can be properly arranged.
The term "longitudinal" in the embodiments of the present disclosure refers to the same horizontal direction as the extending direction of the rail 12, and the term "transverse" refers to the horizontal direction perpendicular to the "longitudinal; the term "vertical" refers to a vertical direction.
In order to prevent radiation leakage, shielding structures or the like may also be provided at appropriate positions of the frame structure, such as at both lateral sides.
As shown in fig. 3 to 5, the movable frame body 21 includes a top beam 211, a vertical arm 212, and a bottom beam 213. The running gear 22 is mounted on the top beam 211. The top ends of the two vertical arms 212 are connected to both ends of the top beam 211, respectively. The bottom beam 213 is disposed below the platform top plate 41, and two ends of the bottom beam 213 are respectively connected to bottom ends of the two vertical arms 212. This arrangement makes the movable frame body 21 integrally square, facilitates the structural strength of the movable frame body 21 itself, thereby facilitating reduction of deformation, and facilitates reduction of relative positional variation between the radiation source 31 and the detector 32 of the scanning device 3, thereby facilitating acquisition of stability and accuracy of images.
In some embodiments of the radiation inspection device, the radiation source 31 comprises a top radiation element 311 and a side radiation element 312; the detector comprises a bottom detection unit 321 and a side detection unit 322.
The radiation inspection device of the embodiment of the present disclosure is beneficial to the scanning unit forming the top view angle, and is also beneficial to the scanning unit forming the side view angle, and the configuration of the scanning apparatus 3 is more flexible.
As shown in fig. 4, wherein the scanning unit of the top view comprises a top radiation unit 311 of the radiation source 31 and a bottom detection unit 321 of the detector 32, may also comprise a side detection unit 322.
As shown in fig. 5, the scanning unit of the side view comprises a side radiation unit 311 of the radiation source 31 and a side detection unit 322 of the detector 32. The scanning device 3 comprises both a scanning unit of a top view angle and a scanning unit of a side view angle.
As shown in fig. 3 to 5, the top radiating unit 311 is disposed on the top beam 211; the side radiating elements 312 are disposed on the vertical arms 212; the side detection unit 322 is disposed on the vertical arm 212; the bottom detecting unit 321 is disposed on the bottom beam 213.
The side detection unit 322 is mounted within the vertical arm 212. The side detection unit 322 constitutes a side detection arm with the vertical arm 212.
The bottom probe unit 321 is mounted within the bottom beam 213. The bottom detecting unit 321 and the bottom beam 213 constitute a bottom detecting arm that reciprocates as a moving member below the platform top 41.
As shown in fig. 1, in some embodiments, the radiation inspection device may further include a ramp 5 disposed at an end of the bottom platform 4, the ramp 5 gradually decreasing in height from the end of the bottom platform 4 to a side away from the bottom platform 4. The slope table 5 is arranged, so that the upper and lower bottom platforms 4 of the detected object are facilitated. For example, the upper and lower bottom platforms 4 of the vehicle are facilitated, so that the passing rate of the detected object is improved, and the detection efficiency is improved.
The ramp 5 and the bottom platform 4 may be separately, detachably connected or integrally provided.
As shown in fig. 1 and 2, in the radiation inspection apparatus of the embodiment of the present disclosure, a bottom detecting unit 321 is provided below a table top 41, and in order to reduce the influence of the bottom table on the image quality as much as possible, the bottom table 4 includes a movable supporting means 42. The movable supporting device 42 includes a plurality of movable supporting portions 421 and driving portions 422 provided corresponding to the plurality of movable supporting portions 421. The driving part 422 is configured to drive the corresponding movable supporting part 421 to switch between the supporting state and the avoidance state. In the supported state, the movable supporting portion 421 abuts against the bottom surface of the platform top plate 41, and the movable supporting portion 421 supports the platform top plate 41. In the retracted state, the movable supporting portion 421 is separated from the bottom surface of the platform top plate 41, so that the movable supporting portion 421 temporarily does not support the platform top plate 41. In the avoidance state, in order for the bottom detection arm to smoothly pass between each movable supporting portion 421 and the platform top plate 41, the interval between each movable supporting portion 421 and the platform top plate 41 is larger than the height of the bottom cross beam 213 and the bottom detection unit 321 thereon (the height of the bottom detection arm), so that the interval between the movable supporting portion 421 and the platform top plate 41 is configured to be suitable for the bottom of the movable frame body 21 to pass between the platform top plate 41 and the movable supporting device 42 in the avoidance state.
In some embodiments, as shown in fig. 2, to enable automatic switching of the operating states of the plurality of movable supports 421, the radiation inspection device further comprises a sensor 6 and a controller 7. The sensor 6 is configured to detect positional information of the bottom probe arm. The controller 7 is in signal connection with the sensor 6 and the driving part 422, and is configured to operate the driving part 422 according to the position information detected by the sensor 6 to drive the movable supporting part 421 to switch between the supporting state and the avoiding state.
The controller 7 may be implemented as a general purpose processor, a programmable logic controller (Programmable Logic Controller, abbreviated as PLC), a digital signal processor (Digital Signal Processor, abbreviated as DSP), an application specific integrated circuit (Application Specific Integrated Circuit, abbreviated as ASIC), a Field-programmable gate array (Field-Programmable Gate Array, abbreviated as FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any suitable combination thereof for performing the functions described in this disclosure.
The movable supporting portion 421 includes, for example, a telescopic cylinder, a nut screw assembly, a cam rod assembly, a cam or a link structure, etc.; the driving part 422 includes an electric motor, a hydraulic motor, or the like. In addition, a transmission device may be provided between the driving portion and the supporting portion as appropriate. The transmission may perform functions such as speed changing, reversing, synchronizing, etc., such as a gear transmission, a gear rack transmission, a worm gear transmission, etc.
By controlling the working state of each movable supporting device 42 to be in a supporting state or an avoiding state, the unobstructed movement and inspection of the bottom detecting unit 321 are realized on the basis of a thinner platform top plate 41 and no or less reinforcing structure, thereby facilitating the acquisition of a clearer top view scanning image by using a lower-power top radiating unit.
Each radiation unit of the aforementioned radiation source may for example comprise an accelerator, an X-ray machine, an isotope emission device, etc. Each of the detection units of the aforementioned detector may include, for example, a gas detector, a semiconductor detector, a scintillation detector, and the like.
In some embodiments, as shown in fig. 1, the bottom platform 4 further includes a fixed supporting device 43, where the fixed supporting device 43 includes a plurality of fixed supporting portions 431 respectively supported at two ends of the platform top plate 41, and the bottom of the movable frame body 21 is located between the plurality of fixed supporting portions 431 at two ends of the platform top plate 41.
The fixed supporting device 43 is arranged, so that the platform top plate 41 is firmly installed, the position is accurate, and the stable placement of the detected object is ensured.
The following describes the working principle of the support platform according to an embodiment of the present disclosure with reference to fig. 1 and 2. In fig. 1, the movable support device 42 is shown with only the telescopic movable support 421, and the rest is not shown, in order to illustrate the operation principle. The portion of the movable frame body 21 interfering with the movable supporting means 42 relates to the bottom cross beam 213 of the movable frame body 21.
In fig. 1, the operation state switching process of the movable frame body 21 is shown from top to bottom with respect to the movable supporting section 421 at the start of a stroke from the right side to the left side. Fig. 2 shows a control block diagram for controlling the operation of the movable supporting section 421. The movable supporting portion 421 is a telescopic rod, and is in a supporting state of abutting against the lower surface of the platform top plate 41 when it extends upward, and is in an avoiding state of being separated from the lower surface of the platform top plate 41 to avoid the movable frame body 21 when it retracts downward.
First, the movable frame body 21 starts to move rightward, the sensor 6 sends the detected position information of the bottom beam 213 to the controller 7, and the controller 7 sends an instruction to the driving part 422 connected with the movable supporting part 421 on the left side of the movable frame body 21 according to the position information, the driving part 422 acts to drive the movable supporting part 421 to shrink downward and gradually move away from the bottom surface of the platform top plate 41, so that the movable supporting part 421 and the platform top plate 41 form a gap enough for the bottom beam 213 of the movable frame body 21 to pass through and be in an avoidance state, and meanwhile, the supporting parts 422 on the other positions keep the supporting state, so as to ensure that the platform top plate 41 has enough supporting force. The bottom beam 213 of the movable housing body 21 then passes through the space. After the controller 7 determines that the bottom beam 213 has passed the movable supporting portion 421 based on the positional information of the sensor 6, it controls the driving portion 422 to drive the movable supporting portion 421 to extend upward until returning to the supporting state. Then the controller 7 drives the corresponding driving part 422 of the next movable supporting part 421 to act so as to switch the next movable supporting part 421 into an avoidance state, after the bottom beam 213 passes, the next movable supporting part 421 extends upwards to return to a supporting state, and so on until the movable frame body 21 moves to the leftmost end of the bottom platform 4, and one scanning is completed. Thus, the movable frame body 21 can move from the right side to the left side without being blocked on the basis of the movable supporting means 42 and the fixed supporting means 43 integrally and stably supporting the platform top plate 41.
Similarly, the movable frame body 21 can move from the left side to the right side without being blocked on the basis of the movable supporting device 42 and the fixed supporting device 43 integrally and stably supporting the platform top plate 41.
In the moving process of the movable frame body 21, the structure between the detected object and the bottom detection unit 321 is always consistent, and is always the platform top plate 41, so that the influence of the platform top plate 41 and the bottom cross beam 213 on the inspection image of the top view angle is kept consistent, the obtained image quality of the top view angle is higher, no additional image is generated, and the image recognition speed is improved.
In some examples, the bottom platform 4 is fixedly connected with the stationary gantry body 11. On the one hand, the arrangement is beneficial to the overall stability of the radiation inspection equipment and the consistency of the relative positions of the scanning device, the platform top plate and the inspected object, thereby being beneficial to acquiring high-quality scanning images. In addition, the requirements on the ground can be further reduced, and the rapid arrangement of the radiation inspection equipment is facilitated. The bottom platform 4 and the fixed frame body 11 may be detachably and fixedly connected, or may be integrally provided.
When the radiation inspection device of the embodiment of the present disclosure performs inspection, an object to be inspected, such as a vehicle, a container, etc., may be parked on the bottom platform 4 through the ramp 5 and located in the scanning channel P, and the scanning device 3 may walk along the track 12 along the arrow direction in fig. 3 under the driving of the walking device 22, and during the walking process, the radiation source 31 emits scanning rays, the detector 32 detects the rays transmitted and/or scattered by the object to be inspected, so as to complete scanning of the object to be inspected, and generate a scanning image through the image generator.
Fig. 6 is a schematic diagram illustrating the working principle of a bottom platform of a supporting platform and a movable supporting device thereof according to another embodiment of the disclosure. The bottom deck and the movable supporting apparatus thereof of the embodiment shown in fig. 6 are different from the bottom deck and the movable supporting apparatus thereof shown in fig. 1 to 2 in that the movable supporting portion 421 is rotatably provided and the switching between the supporting state and the avoiding state thereof is achieved by the rotational movement of the movable supporting portion 421. In the embodiment shown in fig. 6, the movable supporting portion 421 of the movable supporting means rotates around a horizontal rotation axis located at the bottom of the movable supporting portion 421 in the supporting state.
The bottom platform of the embodiment shown in fig. 6 and the non-illustrated parts of its movable support means are referred to the description of the previous embodiments.
Fig. 7 is a schematic diagram illustrating the working principle of a bottom platform of a supporting platform and a movable supporting device thereof according to another embodiment of the disclosure. The bottom platform and its movable support according to the embodiment shown in fig. 7 are identical to the bottom platform and its movable support according to fig. 6 in that the movable support 421 is also rotatably provided and the switching between the support state and the retracted state is achieved by a rotational movement of the movable support 421. Unlike the embodiment shown in fig. 6, in the embodiment shown in fig. 7, the movable supporting portion 421 of the movable supporting means rotates about a horizontal rotation axis located in the middle of the upper and lower directions of the movable supporting portion 421 in the supported state.
The bottom platform of the embodiment shown in fig. 7 and the non-illustrated parts of its movable support means are referred to the description of the previous embodiments.
As can be seen from the description of the above embodiments, in the support platform according to the embodiment of the present disclosure, the two ends of the platform top plate of the bottom platform are fixedly supported by a plurality of fixed support portions, and the middle is supported by a plurality of movable support portions. The platform top plate is used as a bearing structure for directly contacting a plurality of supporting parts with the supported object, and the movable supporting part in the middle part can be switched between a supporting state and an avoiding state, so that the bottom detection arm can reciprocate below the platform top plate and is not influenced by the movable supporting part under the condition of stably supporting the object. The supporting platform is simple in structure and flexible and convenient to use.
Because a plurality of movable supporting parts are arranged, each movable supporting part can be switched between a supporting state and an avoiding state, the detection signals of the bottom detection unit are not influenced by the bottom platform basically, the scanning unit for forming the top view angle is facilitated, and the quality of the inspection image for improving the top view angle is facilitated. Because the bottom detection arm is stably supported all the time in the process of moving below the platform top plate, the platform top plate can be made of a relatively thin flat plate, and therefore, when the support platform is applied to radiation inspection equipment, high-quality imaging effect can be achieved. The support platform is favorable for maintaining the object to be detected to be motionless in the radiation inspection process, and the scanning device moves, so that the whole structure size of the radiation inspection equipment is favorable for being reduced.
Finally, it should be noted that: the above embodiments are merely for illustrating the technical solution of the present disclosure and are not limiting thereof; although the present disclosure has been described in detail with reference to preferred embodiments, those of ordinary skill in the art will appreciate that: modifications may be made to the specific embodiments of the disclosure or equivalents may be substituted for part of the technical features that are intended to be included within the scope of the claims of the disclosure.
