Description
Technical field
The utility model relates to the radiation checking technical field, particularly relates to a kind of folding arm mechanism that is used for vehicle-mounted radiation imaging system.
Background technology
Safety inspection has crucial meaning in fields such as anti-terrorism, strike traffic in drugs smugglings.After the calendar year 2001 U.S.'s 911 incidents, people more and more pay attention to the safety inspection of civil aviation.Along with the deep expansion of hitting the traffic in drugs smuggling, also more and more higher simultaneously to the inspection requirements of air container, railway luggage case etc.
With the vehicular imaging system of the immediate prior art of the utility model be the vehicular imaging system of using by the applicant.With reference to accompanying drawing 8A, 8B and 8C, this vehicular imaging system generally comprises the vehicle and the folding arm mechanism of carrying imaging system, this vehicle comprises vehicle body, pilothouse, this vehicle body is divided into generator bay and check system control cabinet along vehicle heading, described folding arm mechanism is placed when folded state on this vehicle body top compactly so that carry and be transported to the place that needs use by vehicle, wherein the perpendicular feeler arm of folding arm mechanism is positioned at this above canyon, thus described canyon generally do not have the requirement in space therefore can do lower can be at the perpendicular feeler arm of placing on its top after folding.Perpendicular feeler arm after folding generally is positioned on the side of principal arm frame of described folding arm mechanism and the minimum point of perpendicular feeler arm is lower than the minimum point of principal arm frame.In the prior art, the swing bearing position of principal arm frame is positioned on the generator bay, this swing bearing position is lower than the plane at the peak place, top of generator bay from the downward-sloping extension of principal arm frame, therefore the stepped appearance shape is had to make in the top of this generator bay, and two parallel planes that are in differing heights are promptly arranged.Therefore in such vehicular imaging system of prior art, the swivel point in the former folding arm mechanism has caused ballasting, and relatively large secondary arm frame has increased the space that takies the cabin body more.The production and processing of such generator bay is than complexity thereby increased production cost.
In the prior art, generator bay is near pilothouse.Accelerator is positioned at perpendicular feeler arm expansion back and detects so that carry out radiant image with the channel position that the principal arm frame forms, therefore control cabinet is nearer relatively apart from this accelerator target spot in the prior art, if generator bay and control cabinet position are exchanged then can be reduced the influence that radiation brings.Thereby wish the control cabinet at personnel place is moved on on this position to increase the protection to personnel.In the prior art, because of generator bay is not the zone of personnel operation, so sink one structure of generator bay there is no any other problem except producing complicated.But prior art this is designed to the radiation protection level that reaches certain, must cause control cabinet when detected state apart from the accelerator target spot nearer thereby this control bulkhead and the more radiation protection material of top needs.Thereby increased the load-carrying of this onboard system, and reduced the adaptability of this onboard system to various countries' vehicle freight weight limit rules, also increased production cost simultaneously.
The folding arm mechanism of prior art is when needs use, at first need will folding folding arm mechanism to be parallel to ground to vehicle body one sideway swivel roughly 90 degree make this folding arm mechanism be approximately perpendicular to the direct of travel of vehicle, thereby will erect then feeler arm be rotated down about 90 degree should perpendicular feeler arm and principal arm frame approximate vertical and be approximately perpendicular to ground, at this moment, folding arm mechanism launches, perpendicular feeler arm is in a side of vehicle body, thereby being suspended to have formed on the principal arm frame by a linkwork is used for the sense channel zone that object to be detected passes through.The opposite side of vehicle body is shifted in the equipment compartment rotation, and the staff carries out the control corresponding operation in control cabinet.
The utility model content
