Description

Technical Field

[0001] The utility model relates to a foldable green channel vehicle detector and belongs to the technical field of green channel vehicle scanning. Background Art

[0002] In the context of improving the efficiency of road transportation, green-pass vehicles should unify standards and improve transportation timeliness, so that fresh agricultural products can reach the table faster and reduce waste. Automatic detection systems with X-ray functions should be installed at inspection stations and toll stations to identify genuine green-pass vehicles using the principle of X-ray imaging.

[0003] The perspective imaging rapid inspection system in the prior art is generally a gantry-type or straight-column-type rapid inspection system. The two radiation sources of the straight-column-type rapid inspection system cause two paths of radiation to irradiate two columns of detectors respectively. The data of the two columns of detectors overlap at a large angle. When the data of the two columns of detectors are fused and calculated, the image fusion of the loaded vehicle has a certain distortion. The greater the effective density of the load, the more serious the distortion. The gantry-type rapid inspection system has a crossbeam on the top. Once the toll station needs to pass an overheight vehicle, the rapid inspection system must be temporarily disassembled and reassembled after passing, which is inconvenient. Utility Model Content

[0022] like Figure 1As shown, this embodiment provides a foldable green channel vehicle detector, comprising: a transmitting end column 1, a receiving end column 2, a ray source 3, a detector 4 and a rotary drive device 5, wherein the transmitting end column 1 is arranged relative to the receiving end column 2, the ray source 3 is arranged in the transmitting end column 1, and the detector 4 is arranged in the receiving end column 2;

[0023] The receiving end column 2 adopts an L-shaped design, including: a horizontal arm 21 and a vertical arm 22. The top end of the vertical arm 22 is hinged to the rear end of the horizontal arm 21, the front end of the horizontal arm 21 is arranged toward the transmitting end column 1, and the rear end of the horizontal arm 21 is hinged to a rotary drive device 5 for rotating the horizontal arm 21.

[0024] The slewing drive device 5 includes: a hydraulic cylinder and a bracket 51, wherein the bracket 51 is horizontally connected to the upper part of the receiving end column 2, and hinge points for hinge connection of the hydraulic cylinder are arranged on the upper side of the bracket 51 and the lower side of the cross arm 21.

[0025] The hydraulic cylinder is tiltedly arranged on the bracket 51 .

[0026] Furthermore, the height of the vertical arm 22 of the receiving end column 2 is: 6 meters

[0027] The length of the cross arm 21 of the receiving end column 2 is: 4m.

[0028] The bottoms of the transmitting end column 1 and the receiving end column 2 are relatively fixed on the embedded parts of the installation foundation respectively.

[0029] The detectors 4 are distributed in an array form on the inner sides of the horizontal arm 21 and the vertical arm 22 facing the transmitting end column 1 .

[0030] The ray source 3 is installed in the transmitting cabinet. During normal measurement, the horizontal arm 21 and the vertical arm 22 of the receiving end column 2 remain L-shaped and fixed.

[0031] When the cross arm 21 is raised and rotated, the upward angle is 35°; when the cross arm 21 is folded and rotated, the folded angle is 65°, with the horizontal position of the cross arm 21 being 0°.

[0032] Working process:

[0033] like Figure 2~3 As shown, during normal measurement of the utility model, the cross arm equipped with the detector remains unchanged, and detection is performed according to the received radiation source information;

[0034] When an over-width or over-height vehicle passes, the rod end of the electric control hydraulic cylinder will be retracted to push up the cross arm equipped with the detector, and mechanical parts can be used to limit the position to ensure the safe passage of the vehicle;

[0035] When an over-height vehicle passes and the raised cross arm cannot ensure the vehicle's passage, the rod end of the electric control hydraulic cylinder extends and the cross arm equipped with the detector is folded inward to allow the vehicle to pass safely.

[0036] Considering the passage of super-high vehicles, the utility model sets a folding structure controlled by a hydraulic cylinder to convert hydraulic energy into mechanical energy and fold the receiving column to ensure that the width after folding does not exceed the safety roundabout, so that super-wide and super-high vehicles can pass;

[0037] Secondly, the utility model enables the vehicle to be inspected while driving, can automatically determine the condition of the vehicle to be inspected, and uses one ray emission source to completely cover the irradiated object, saving costs and avoiding the distortion caused by multiple images obtained by multiple ray emission sources and multiple image data.
