One side of the opening of the detector manifold 15 is connected to the circular arc detector manifold 15.
如图2所示，旋转弧形探测器1通过带孔的回转支承件11固定在回转轴10上，回转支撑件11上的孔套合在回转轴10上，回转支撑件11固定在旋转弧形探测器1远离开口部一侧。As shown in Fig. 2, the rotary arc detector 1 is fixed to the rotary shaft 10 via a perforated rotary support member 11, and the hole in the rotary support member 11 is fitted over the rotary shaft 10, and the rotary support member 11 is fixed to the rotary arc. The shape detector 1 is away from the side of the opening.
如图2、图3至图5所示，旋转弧形探测器的转动机构2是电动推杆装置，电动推杆装置包括通过通电自动伸缩的连接杆20，电动伸缩杆包括两个端部，其中一个端部固定在X射线检查设备上，另一个端部连接旋转弧形探测器1远离开口部一侧的牵引轴上22，牵引轴22与回转轴10之间有足够大的距离。电动伸缩杆2对旋转弧形探测器1的力矩足够大，使旋转弧形探测器1沿回转轴10转动。为了进一步提高旋转弧形探测器在电动推杆装置伸缩时灵活转动，电动推杆装置的伸缩杆的一端是通过转动轴21固定在X射线检查设备上的。在电动伸缩杆伸缩时，电动推杆装置也沿转动轴转动。在此需要说明的是，本发明中，转动机构2不限于电动推杆装置，能使旋转弧形探测器1沿回转轴10转动的装置都可以实现本发明(例如，液压装置、气动装置、齿轮、链轮等传动机构。)。As shown in FIG. 2, FIG. 3 to FIG. 5, the rotating mechanism 2 of the rotating arc detector is an electric push rod device, and the electric push rod device includes a connecting rod 20 that automatically expands and contracts by energization, and the electric telescopic rod includes two end portions. One of the ends is fixed to the X-ray inspection apparatus, and the other end is connected to the traction shaft 12 on the side of the rotating curved detector 1 away from the opening, and the traction shaft 22 is sufficiently distant from the rotary shaft 10. The torque of the electric telescopic rod 2 to the rotating arc detector 1 is sufficiently large to rotate the rotary arc detector 1 along the rotary shaft 10. In order to further improve the flexible rotation of the rotating arc detector during the expansion and contraction of the electric push rod device, one end of the telescopic rod of the electric push rod device is fixed to the X-ray inspection device by the rotating shaft 21. When the electric telescopic rod is stretched, the electric push rod device also rotates along the rotating shaft.

The line connecting the center of the detector crystal 5 and the target is perpendicular to the tangent of the detector crystal 5 and the arc. The connection between the center of each detector crystal 5 and the target line is the best for receiving energy when the corresponding detector crystal 5 is perpendicular to the tangent of the circular arc. Multiple detector crystals 5 In the range of a certain angle of the radiation of the radiation generating device 3, the adjacent detector crystals are arranged side by side and equidistantly arranged from the target of the emission source, and the spacing of the adjacent detector crystals is not more than 0.5 mm. With this arrangement, the L-type detector effectively reduces the scattering problem of the ray, and the effect is better in reducing the scattering and improving the resolution of the wire. In addition, the theoretical gap of adjacent detector crystals is small, and there is no spatial reflection of rays, which can effectively reduce the scattering of edge rays.

Before installation, the detector crystals 5 are relatively straight and slit in the same reference plane by means of an open area such as an external platform. That is, the reference of each detector crystal 5 is uniform, and the relative positions are identical. This is easy and convenient to operate, and it is easy to find the datum. The two-channel security inspection machine based on the rotating arc detector 1 provided by the invention forms two different correction tables in the self-test process. When different channels are selected, the corresponding correction table is called, and the corresponding radiation generating device 3 emits X. The beam of light meets the corresponding channel application and achieves corresponding image processing.
下面以基于旋转弧形探测器1的双通道安检机应用于双通道X射线检查设备为例，对基于旋转弧形探测器1的双通道安检机的工作过程详细说明。本旋转弧形探测器1旋转动力采用电动推杆装置2驱动，旋转弧形探测器1旋转至左、右两个通道时采用两套基准定位装置定位旋转弧形探测器1的旋转到位情况，基准定位装置优选是带接近传感器的探测器基准块。如图3所示，当使用左通道时，左侧射线发生装置3射出X射线光束，连接杆20打开伸出，旋转弧形探测器1绕回转轴10顺时针旋转。当旋转弧形探测器1向左旋转到位后，通过探测器左基准块定位旋转弧形探测器1的旋转面的相对位置，利用探测器左基准块的接近传感器确定旋转到位情况，实现旋转弧形探测器1在左通道的准确到位。同理当使用右通道时，如图4所示，右侧射 线发生装置3射出X射线光束，连接杆20收缩，旋转弧形探测器1绕回转轴10逆时针旋转。当旋转弧形探测器1向右旋转到位后，通过探测器右基准块定位旋转弧形探测器1的旋转面的相对位置，利用探测器右基准块的接近传感器确定旋转到位情况，实现旋转弧形探测器1在右通道的准确到位。旋转弧形探测器1在两个通道之间绕回转轴10切换时，各个探测器晶体5相对应靶点位置一致，也就是发射和接收距离相差不大，实现两通道指标的变化一致性，便于图像处理。本发明通过旋转机构实现不同通道的不同X光机的射线探测需求，根据安检机的输送带信号接收到的货物信号，驱动电动推杆装置2，实现对应的收缩和打开，选择性的根据探测器左/右基准块的传感器准确定位，成为不同通道的探测器。The following is a detailed description of the working process of the dual-channel security inspection machine based on the rotating curved detector 1 by using a two-channel security inspection machine based on the rotating curved detector 1 as an example for a two-channel X-ray inspection apparatus. The rotating power of the rotating arc detector 1 is driven by the electric push rod device 2, and when the rotating curved detector 1 is rotated to the left and right channels, two sets of reference positioning devices are used to position the rotating arc detector 1 to rotate. The reference positioning device is preferably a detector reference block with a proximity sensor. As shown in FIG. 3, when the left channel is used, the left ray generating device 3 emits an X-ray beam, the connecting rod 20 is opened and extended, and the rotating curved detector 1 is rotated clockwise around the rotary shaft 10. After the rotating arc detector 1 is rotated to the left, the relative position of the rotating surface of the rotating arc detector 1 is positioned by the left reference block of the detector, and the rotation sensor is determined by the proximity sensor of the left reference block of the detector to realize the rotating arc. The shape detector 1 is accurately positioned in the left channel. Similarly, when using the right channel, as shown in Figure 4, the right side shot The line generating device 3 emits an X-ray beam, the connecting rod 20 contracts, and the rotating curved probe 1 rotates counterclockwise about the rotary shaft 10. After the rotating arc detector 1 is rotated to the right, the relative position of the rotating surface of the rotating arc detector 1 is positioned by the right reference block of the detector, and the rotation sensor is determined by the proximity sensor of the right reference block of the detector to realize the rotating arc. The shape detector 1 is accurately positioned in the right channel. When the rotating arc detector 1 is switched between the two channels around the rotary axis 10, the positions of the respective detector crystals 5 corresponding to the target point are the same, that is, the transmission and reception distances are not much different, and the change of the two-channel index is consistent. Easy to image processing. The invention realizes the radiation detection requirements of different X-ray machines of different channels by the rotating mechanism, drives the electric push rod device 2 according to the cargo signal received by the conveyor belt signal of the security inspection machine, realizes the corresponding contraction and opening, and selectively according to the detection. The sensors of the left/right reference block are accurately positioned to become detectors for different channels.
