[0038] The above embodiments can be summarized based on the following description in conjunction with the accompanying drawings.
[0039] like Figure 1 As shown, a truck cab avoidance device for protecting drivers requiring scanning and inspection includes a detection device fixed to the side of the truck's necessary route to scan and inspect the truck compartment, a distance measuring device 1 to measure the distance between the truck cab 4 and the truck cab-to-compartment connection 5, and a control device that controls the detection device based on data obtained from the distance measuring device 1. The detection device is a radiographic scanning device, and the truck cab avoidance device requires at least one distance measuring device 1. When all distance measuring devices 1 measure the desired information, the control device controls the detection device to immediately operate.
[0040] The distance measuring device 1 is fixed at least on one side of the route that the truck must pass through. Figure 2 As shown, the distance measuring device 1 is fixed on the left side of the route that the truck must pass through; Figure 3 As shown, the distance measuring device 1 is fixed on the right side of the route that the truck must pass through; Figure 4 As shown, the distance measuring device 1 is fixed on the upper side of the route that the truck must pass through; Figure 5 and Figure 6 As shown, the distance measuring device 1 is fixed on the left side, right side and upper side of the route that the truck must pass through.
[0041] like Figure 1-6As shown, the truck can also travel in the opposite direction through the plane 3 of the detection device perpendicular to the truck's route to inspect the train car. The truck can first pass through the plane 2 of the distance measuring device 1 perpendicular to the truck's route, and then pass through the plane 3 of the detection device perpendicular to the truck's route; or it can first pass through the plane 3 of the detection device perpendicular to the truck's route, and then pass through the plane 2 of the distance measuring device 1 perpendicular to the truck's route. The vertical distance between the plane 3 of the detection device perpendicular to the truck's route and the plane 2 of the distance measuring device 1 perpendicular to the truck's route does not exceed 100 mm.
[0042] In some embodiments, as Figure 5 As shown, when the cab-carriage connection 5 reaches the plane 2 of the distance measuring device 1 perpendicular to the route the truck must pass through, and all the distance measuring devices 1 measure the expected information, the control device controls the detection device to work immediately, and the truck car passes the plane 3 of the detection device perpendicular to the route the truck must pass through. Figure 6 As shown, when the truck compartment leaves the distance measuring device 1 and the plane 2 perpendicular to the route the truck must pass through, the control device controls the detection device to stop working.
