Patent Images
1. A trailer security inspection system, comprising:
- a protective wall forming an inspection passage for passage of a trailer;
a radiation imaging system effecting a security inspection of the trailer passing through said inspection passage; and
a traction arrangement adapted for hauling the trailer;
wherein;
the traction arrangement comprises;
a machine base;
a guide rail mounted on the machine base;
a slide cooperating with the guide rail;
a rotatable traction arm rotatably connected to the slide via a rotation shaft; and
a drive arrangement driving the slide to move along the guide rail;
the drive arrangement comprises a positive and reverse rotatable decelerating motor mounted on the machine base and a transmission mechanism;
the transmission mechanism comprises two chain wheels and a chain cooperating with the two chain wheels;
one of the two chain wheels is coupled to an output shaft of the motor; and
the slide is connected to the chain.

5. A trailer security inspection system, comprising:
-
a protective wall forming an inspection passage for passage of a trailer; a radiation imaging system effecting a security inspection of the trailer passing through said inspection passage; a traction arrangement that is adapted for hauling the trailer and that comprises; a machine base; a guide rail mounted on the machine base; a slide cooperating with the guide rail; a rotatable fraction arm rotatably connected to the slide via a rotation shaft, wherein, mounted on the slide are first and second stops limiting a rotation scope of the traction arm; and a drive arrangement driving the slide to move along the guide rail; an automatic expanding mechanism that urges the traction arm to rotate; and a locking arrangement adapted for locking the traction arm. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A trailer security inspection system, comprising:
-
an inspection passage; a radiation imaging system that performs a security inspection of a trailer when the trailer is at a predetermined position within the inspection passage; and a traction arrangement adapted for hauling the trailer, wherein the traction arrangement includes; a guide rail; a slide connected to and slidable along the guide rail; a traction arm rotatably connected to the slide via a rotation shaft and having mounted thereon a hook; an automatic expanding mechanism; a locking mechanism; an unlocking mechanism; and a drive arrangement configured to; drive the slide along the guide rail in a first linear direction towards an entrance of the inspection passage, the driving of the slide in the first direction causing engagement of the traction arm with the automatic expanding mechanism, the engagement with the automatic expanding mechanism causing the traction arm to rotate about the rotation shaft in a first rotating direction towards the entrance until the traction arm is locked in a locked state by the locking mechanism thereby preventing the traction arm from rotating in a second rotating direction reverse of the first rotating direction, the trailer being connectable to the hook when the traction arm is in the locked state; and subsequent to the locking of the traction arm in the locking position, drive the slide in a second linear direction reverse of the first linear direction towards an unlocking position at which the unlocking mechanism engages the locking mechanism to release the traction arm from the locked state, the driving of the slide causing the traction arm and connected trailer to pass through the predetermined position prior to reaching the unlocking position, the traction arm being rotatable about the rotation shaft in the second rotating direction after release of the traction arm from locked state. - View Dependent Claims (15, 16, 17, 18, 19, 20)
