Elevator mechanism for vehicle-mounted radiation detection system and vehicle-mounted radiation detection system

The invention discloses an elevator mechanism for a vehicle-mounted radiation detection system and the vehicle-mounted radiation detection system, and relates to the technical field of detection of large objects, such as containers. The elevator mechanism comprises a driving motor and at least two spiral elevators, wherein the driving motor is respectively connected with the spiral elevators through a transmission device; the lower ends of elevating rods of the spiral elevators are used for connecting radiation detection equipment; and the elevator mechanism also comprises a mounting component used for connecting the elevator mechanism onto a vehicle body of the vehicle-mounted radiation detection system. According to the elevator mechanism and the vehicle-mounted radiation detection system, the radiation detection equipment is driven by the at least two spiral elevators to move in the height direction, so that the condition that the elevator mechanism is arranged in a narrow transverse space is avoided, and the adjusting stability is improved. Since the elevator mechanism is arranged in the vehicle-mounted radiation detection system, the vehicle-mounted radiation detection system is more convenient to mount, more compact in structure, more stable in adjustment, and is stronger in applicability.
