    摘要： A fork-arm lift tractor includes a vehicle body, a supporting plate disposed above the vehicle body, a lifting device for driving the supporting plate to be lifted, a front and rear fork-arm assemblies, a front and rear fork-arm drive assemblies. The front fork-arm assembly includes two front fork-arms rotatably disposed at the supporting plate. The rear fork-arm assembly includes two rear fork-arms rotatably disposed at the supporting plate, and the front and rear fork-arms may be deployed or retracted from both sides of the supporting plate. The front fork-arm driving assembly includes a front transmission part, and a front power device disposed at the supporting plate and may drive the front transmission part to move horizontally linearly so as to rotate the two front fork-arms. The rear fork-arm driving assembly has almost the same structure of the front fork-arm driving assembly and is used to rotate the two rear fork-arms.

    摘要： A vehicle detection system includes a transverse detector arm, two vertical detector arms, a radiation source, a plurality of transverse detectors, and a plurality of vertical detectors. The transverse detector arm may be disposed on the ground. Two vertical detector arms are disposed at both ends of the transverse detector arm. The radiation source is located above the transverse detector arm. A plurality of transverse detectors are disposed within the transverse detector arm and are laid along a length direction of the transverse detector arm for receiving ray emitted by the radiation source. The plurality of vertical detectors are symmetrically disposed on the two vertical detector arms, and each of the vertical detectors is disposed towards a center point of the radiation source for receiving ray emitted by the radiation source.

    摘要： The present disclosure relates to a vehicle positioning apparatus. An implementation may comprise a base provided with a recess, wherein each of two opposite sides of an upper edge of the recess are rotatably provided with a flap, and wherein a power unit may be provided on an outer side of a corresponding flap opposite to the recess. Further, the power unit may be adapted for driving the corresponding flap to transfer between a first supporting position and a second supporting position inclining downwardly, wherein the first supporting position is in a range from a position higher than the second supporting position to a position in a same plane as an upper surface of the base. Such vehicle positioning apparatus may achieve precise positioning of a whole vehicle, such as via the wheels of the vehicle, yielding high positioning accuracy, with simple structure, stable transmission, and low production cost.

    摘要： The present disclosure relates to vehicle traction apparatus and radiation imaging check systems. One illustrative implementation may comprise two parallel tracks, two sets of traction mechanisms and a driving unit, wherein the tracks are disposed on a ground. The two sets of traction mechanisms may be respectively disposed on the two tracks. Further, the driving unit may be adapted for driving the two sets of traction mechanisms to synchronously move along the two tracks. In some embodiments, each of the two sets of traction mechanisms includes a body, a cantilever, a lifting driving mechanism and a wheel supporting assembly, and may include features such as the body being mounted on the track, the cantilever being disposed parallel to a direction of the tracks, and/or both ends of the cantilever being respectively connected with the lifting driving mechanism and the wheel supporting assembly.
