Rail clamping device structure

Abstract

The invention discloses a rail clamping device structure (20) which comprises a frame (1), a cam mechanism (7) and clamp plates (3, 6), wherein the cam mechanism (7) is installed on the frame (1) and can rotate around the rotating center thereof; the clamp plates (3, 6) are pivoted to the frame (1) through an axis pin (11); one ends of the clamp plates (3, 6) can be connected between a first position (A') and a second position (B') of the cam mechanism (7), thereby driving the clamp plates (3, 6) to pivot around the axis pin (11) and driving the pivoting movement corresponding to the pivoting movement of the clamp plates (3, 6) around the axis pin (11); and the other ends of the clamp plates (3, 6) can respectively form a joint with a rail (17) to realize clamping and disengagement, thereby realizing releasing.

Description

technical field [0001] The invention relates to a rail-type X-ray safety inspection system, in particular to a rail clamp structure used in the system. Background technique [0002] At present, there are two main working modes of the security inspection system: the first one is that during the security inspection operation, the radiation source and detector are not fixed, and the inspection items are scanned through the movement of the radiation source and detector. The second is that the radiation source and the detector are stationary during the security inspection operation, and the inspected items can pass through the radiation scanning area to complete the scanning. Among them, the second working method is divided into two categories: one is a fixed workplace, such as a luggage security inspection system, and the other is an unfixed workplace, such as a vehicle-mounted security inspection system. [0003] In the customs cargo security inspection in some port cities, th...

AI Technical Summary

Problems solved by technology

If the security inspection machine is used to work in a fixed workplace, all items need to be transported to the entrance of the security inspection machine one by one for security inspection. This method needs to carry all the inspected goods, and the workload is too large

With the above-mentioned vehicle-mounted mobile inspection equipment, it is necessary to transfer the vehicle-mounted safety inspection system to each inspection place, and the vehicle-mounted mobile inspection equipment has strict restrictions on the volume and weight of the inspected goods, and the working space of the equipment operator is narrow.
