Detailed Description
Embodiments of the present disclosure provide a security inspection apparatus, including: a radiation source which emits radiation; and a detector for detecting radiation emitted by the radiation source, wherein the radiation source and the detector define a security screening path. The source may be an X-ray source or other source. FIG. 1 shows a transmission-type security inspection apparatus, a radiation source and a detector arranged opposite the radiation source defining a security inspection channel; however, the security device may be, for example, a backscatter type security device, in which case the source and detector may be located on the same side and the object being inspected may pass over the security path to be inspected.
In one embodiment, the security device may comprise a shielding housing 1-3, the shielding housing 1-3 being composed of a material capable of shielding radiation, comprising an inlet and an outlet, the security channel being located between the inlet and the outlet of the shielding housing 1-3. Lead door curtains can be arranged at the inlet of the shielding shell 1-3
In one embodiment, the security inspection apparatus may include an entrance additional tape machine 1-6 and an exit additional tape machine 1-5, as shown in fig. 1, the entrance additional tape machine 1-6 having an inclined slope so as to send the articles to the conveyor in the security inspection lane, after the inspection is completed, the articles are sent to the ground through the exit additional tape machine 1-5. In one embodiment, one end of the transfer device protrudes out of the entrance of the shielding housing 1-3 and the other end protrudes out of the exit of the shielding housing 1-3. The inlet attachment tape machine 1-6 is arranged at one end of the conveyor which protrudes out of the inlet of the shielding housing 1-3, and the outlet attachment tape machine 1-5 is arranged at the other end of the conveyor which protrudes out of the outlet of the shielding housing 1-3.
In this embodiment, the security inspection apparatus includes a conveyor 1-2 arranged on a security inspection channel for conveying inspected articles. The articles to be inspected include articles such as luggage, and a cart 1-1 for transporting luggage is also provided at an airport. In the present embodiment, the transfer device 1-2 includes a traction device 2-2 to push the wheels 3-2. This is advantageous in that the conveyor 1-2 comprises traction means 2-2 for pushing e.g. wheels 3-2 of the trolley 1-1, whereby the trolley 1-1 with wheels 3-2 can be pushed through the screening tunnel, so that no baggage is removed from the trolley 1-1 and then re-inspected before being re-loaded onto the trolley 1-1, making screening more convenient and quick.
The conveyor 1-2 further includes a conveyor belt 2-1 configured to support the inspected article and convey the supported inspected article. This is advantageous in that the conveyor 1-2 is thus able to convey baggage through the screening tunnel; in other words, the conveyor 1-2 of the present embodiment is configured in such a manner that it is possible to convey articles such as luggage and the like through the security inspection passage by the conveyor belt 2-1, and also to convey the easily movable cart 1-1 having wheels 3-2, such as a trolley for carrying things and the like, particularly a luggage cart used in an occasion such as an airport, by the traction device 2-2, thereby allowing passengers carrying any articles and/or the cart 1-1, such as an airport or a station, to conveniently pass through the security inspection apparatus, and improving the speed and efficiency of security inspection.
In one embodiment, the conveyor 1-2 further comprises a guide slot 2-5 provided in the conveyor 1-2. In this embodiment, the conveyor belt 2-1 is divided into two parts; the traction means 2-2 are arranged in the guide groove 2-5. In the present embodiment, the traction device 2-2 is disposed in the guide groove 2-5 of the conveyor 1-2, so that the traction device 2-2 does not affect the conveyor belt 2-1 to convey articles such as luggage. However, in other embodiments, the conveyor 1-2 may not include the guide groove 2-5, and the traction device 2-2 is disposed on one or both sides of the conveyor 2-1; alternatively, in one embodiment, the traction device 2-2 is disposed on the upper portion of the conveyor belt 2-1, and although the traction device 2-2 is disposed on the conveyor belt 2-1, the conveyor belt 2-1 has a remaining flat portion, so that the conveyor belt 2-1 still meets the need for conveying articles such as luggage.
In one embodiment, the conveyor 1-2 comprises a pair of drums 2-4, 2-6, and the two portions of the conveyor belt 2-1 form a loop through the pair of drums 2-4, 2-6 for endless movement in the loop. The pair of drums 2-4, 2-6 are rotated simultaneously so that the conveyor belt 2-1 around the pair of drums 2-4, 2-6 can be driven in a loop. Typically, in this arrangement of the conveyor belt 2-1 and the pair of drums 2-4, 2-6, the pair of drums 2-4, 2-6 will moderately tension the conveyor belt 2-1 to move the conveyor belt 2-1.
In one embodiment, the traction device 2-2 includes a flexible drive mechanism and at least one traction rail 3-3 disposed on the flexible drive mechanism that forms a loop that operates to transfer the at least one traction rail 3-3 on the flexible drive mechanism from one end of the security screening channel to the other (e.g., an inlet of the shielding housing 1-3 to an outlet of the shielding housing 1-3). The traction rail 3-3 is configured to abut against the wheel 3-2 to push the wheel 3-2 into movement. When the cart 1-1 with wheels 3-2 is pushed by a passenger to the entrance on the left side of the security inspection device as shown in fig. 1 and 2, the wheels 3-2 of the cart 1-1 ride over one traction rail 3-3 through the action of the passenger cart 1-1, or the traction rail 3-3 moves along with the flexible transmission mechanism along the loop formed by the flexible transmission mechanism, and when the wheels 3-2 enter, the traction rail 3-3 abuts against the wheels 3-2 from the rear of the wheels 3-2 along with the movement of the flexible transmission mechanism, and a transverse force is applied to the wheels 3-2 to push the wheels 3-2 to move forwards. The point at which the traction rail 3-3 contacts the wheel 3-2 is at the upper part of the circumference of the wheel 3-2, i.e. the height of the point at which the traction rail 3-3 contacts the wheel 3-2 is greater than the radius of the wheel 3-2, or the point at which the traction rail 3-3 contacts the wheel 3-2 is above the level of the axis of the wheel 3-2, so that the traction rail 3-3 pushes the wheel 3-2 over the upper half circumference of the wheel 3-2, and the trolley 1-1 is thus pushed through the security screening channel by the traction rail 3-3. In one embodiment of the present disclosure, a traction rail 3-3 is provided that includes a traction shaft 4-3 and a traction sleeve 4-2 that is sleeved over the traction shaft 4-3, the traction shaft 4-3 being connected to a flexible band-like material, the traction sleeve 4-2 being rotatable about the traction shaft 4-3. The traction sleeve 4-2 may be supported on the traction shaft 4-3 by traction bearings 4-1. Such a configuration allows the wheels 3-2 to ride over the traction sleeves 4-2 of the traction rails 3-3, the rotation of the traction sleeves 4-2 allowing the wheels 3-2 to ride easily over the traction axles 4-3, the traction sleeves 4-2 being rotatable during movement of the push cart 1-1 thereby allowing the wheels 3-2 to rotate; also, as the wheels 3-2 leave the traction rail 3-3, rotation of the traction sleeve 4-2 of the traction rail 3-3 reduces friction with the wheels 3-2.
Here, other parts of the cart 1-1 may be placed on the conveyor belt 2-1. However, in other embodiments, the traction device 2-2 of fig. 3 may be arranged solely within the security screening tunnel, such that the other wheels 3-2 of the trolley of the other pulleys (where the trolley 1-1 dedicated to the airport requires the traction device 2-2 to pull the rear wheel because the rear wheel is braked) may be on the ground, the trolley may be pushed by the traction device 2-2 to move through the security screening tunnel; the conveyor belt 2-1 may or may not be arranged in the security inspection channel at this time. The security inspection channel may be provided with only the traction means 2-2, thereby providing a security inspection channel of e.g. a separate inspection trolley 1-1, which is also advantageous in a manner of sorting the inspections.
In one embodiment, the flexible drive mechanism of the traction device 2-2 comprises a flexible strip material 3-1 and two traction rotating shafts 3-0, wherein the flexible strip material 3-1 forms a loop around the two remote traction rotating shafts 3-0, and the flexible strip material 3-1 is circularly operated in the loop through the rotation of the two traction rotating shafts 3-0. The traction spindle 3-0 of this embodiment may be different from the drums 2-4, 2-6 described above; however, in one embodiment, the pulling roll 3-0 may be omitted and the flexible strip material 3-1 wrapped around the pair of drums 2-4, 2-6, the drums 2-4, 2-6 tensioning the flexible strip material 3-1 and moving the flexible strip material 3-1. The configuration mode can simplify the complexity of the whole equipment and reduce the cost. In one embodiment, the flexible strip material 3-1 may be a chain; the flexible strip material 3-1 may be a belt. The traction rail 3-3 may be secured to the flexible strip 3-1 by, for example, welding, fasteners, or other attachment means; the traction rail 3-3 may be a plurality of traction rails 3-3 distributed over the loop of flexible strip material 3-1 as the flexible strip material 3-1 moves.
In one embodiment, the flexible transmission mechanism comprises two flexible band-shaped materials 3-1, and both ends of at least one traction rail 3-3 are fixedly connected to the two flexible band-shaped materials 3-1, respectively, so as to be disposed between the two flexible band-shaped materials 3-1 and arranged in a direction transverse to the running direction of the two flexible band-shaped materials 3-1. The wheels 3-2 of the trolley 1-1 can be placed in the space between the two flexible band-shaped materials 3-1 and the traction rail 3-3, the traction rail 3-3 being moved with the two flexible band-shaped materials 3-1 along the loop formed by the flexible band-shaped materials 3-1, so as to push the wheels 3-2 forward. This arrangement can stably push the wheel 3-2 forward. It is advantageous to provide a plurality of traction rails 3-3 on two flexible strip materials 3-1, so that the wheels 3-2 of the cart 1-1 can be pushed faster by one traction rail 3-3 provided on the flexible strip material 3-1 without waiting for one traction rail 3-3 to run a week and for too long.
In one embodiment, one end of the traction rail 3-3 is fixedly secured to the flexible strip material 3-1 and disposed in a direction transverse to the direction of travel of the flexible strip material 3-1. In this embodiment, the flexible band material 3-1 may be one, and one end of the traction rail 3-3 is fixedly connected to the flexible band material 3-1 and extends in a lateral direction (not shown), for example, one end of the traction shaft 4-3 of the traction rail 3-3 is connected to the flexible band material 3-1, and the traction sleeve 4-2 of the traction rail 3-3 protrudes in the lateral direction of the flexible band material 3-1 for contacting the wheel 3-2 and pushing the wheel 3-2 to move. One traction rail 3-3 can push the wheels 3-2 forward, allowing to simplify the construction of the traction device 2-2 and the whole security device.
In one embodiment, the traction device 2-2 includes a flexible drive mechanism and at least one clamping mechanism 5-1 disposed on the flexible drive mechanism that forms a loop cycle for transferring the at least one clamping mechanism 5-1 on the flexible drive mechanism from one end of the security channel to the other. In this embodiment, at least one clamping mechanism 5-1 is configured to clamp the wheel 3-2 to bring the wheel 3-2 to transfer the wheel 3-2 from one end of the security channel to the other. In this embodiment, at least one clamping mechanism 5-1 is provided on the flexible strip material 3-1 of the flexible drive mechanism, said flexible strip material 3-1 being circulated along the loop for transferring the at least one clamping mechanism 5-1 provided on the flexible strip material 3-1 from one end of the security channel to the other, for example from the inlet to the outlet of the shielding housing 1-3. A plurality of clamping mechanisms 5-1 are provided on the flexible strip material 3-1 of the flexible transmission mechanism so that the wheels 3-2 of the cart 1-1 can be more quickly gripped by one of the clamping mechanisms 5-1 provided on the flexible strip material 3-1 to be pushed without waiting too much time.
In one embodiment, as shown in FIG. 6, at least one clamping mechanism 5-1 includes a channel housing 6-0, and clamping blocks 6-1 disposed on two sidewalls 6-01 (e.g., top) of the channel housing 6-0, the clamping blocks 6-1 being arranged to bear against both sides of the wheel 3-2 and apply a force toward the wheel 3-2 when the wheel 3-2 is placed between the two clamping blocks 6-1. The two clamp blocks 6-1 have elasticity, and the two clamp blocks 6-1 are pressed by the wheel 3-2 to be elastically deformed when the wheel 3-2 is placed between the two clamp blocks. Specifically, one end of the clamping block 6-1 is connected to one side wall 6-01 of the groove-shaped housing 6-0, the clamping block 6-1 extends from one end connected to the one side wall 6-01 of the groove-shaped housing 6-0 toward between the two side walls 6-01 of the groove-shaped housing 6-0, for example, may extend along a portion of an ellipse or a circle, or may extend along a portion of another shape such that the other ends of the two clamping blocks 6-1 are close to each other, the minimum distance between the two clamping blocks 6-1 may be the other ends of the two clamping blocks 6-1, or may be other portions of the two clamping blocks 6-1, for example, when the two clamping blocks have an arc shape, the ends of the clamping blocks 6-1 retract toward the side walls, and the distance between the intermediate portions of the clamping blocks 6-1 is the shortest. When the wheel 3-2 is pressed between the two clamp blocks 6-1 due to gravity, the two clamp blocks 6-1 are pressed by the wheel 3-2 to be elastically deformed, or the wheel 3-2 is clamped by the two clamp blocks 6-1. In this embodiment, the clamp blocks 6-1 have arc-shaped tops, and the axle of the wheel 3-2 may rest on the arc-shaped tops of the two clamp blocks 6-1 (closest portions of the two clamp blocks 6-1), with the lower semicircle of the axle of the wheel 3-2 being clamped by the closest portion of the clamp blocks 6-1. The free ends of the two clamping blocks 6-1, which are not connected to one side wall 6-01 of the groove housing 6-0, can each be oriented in a direction away from each other, so that the free ends of the clamping blocks 6-1 do not interfere with the lower semicircle of the axle of the wheel 3-2 from the clamping blocks 6-1.
In one embodiment, as shown in fig. 7, the two clamp blocks 6-1 are supported toward the middle of the two side walls 6-01 of the channel housing 6-0 by the respective torsion springs 6-2, and the two clamp blocks 6-1 are pressed by the wheel 3-2 while compressing the respective torsion springs 6-2 toward the two side walls 6-01 of the channel housing 6-0 when the wheel 3-2 is placed between the two clamp blocks 6-1.
In another embodiment, as shown in FIG. 7, two clamp blocks 6-1 are each pivotally connected to a corresponding side wall 6-01 of a channel housing 6-0 by a respective bar shaft 6-3, wherein the bar shaft 6-3 includes a bar 6-30 extending transversely and upwardly from the bar shaft 6-3 in the direction of axial extension. The two clamp blocks 6-1 have mutually facing surfaces, both sides of the wheel 3-2 are respectively abutted against one of the mutually facing surfaces of the two clamp blocks 6-1, and the wheel 3-2 presses the two clamp blocks 6-1 because the distance between the mutually facing surfaces of the two clamp blocks 6-1 is smaller than the thickness of the wheel 3-2. In this embodiment, the two clamp blocks 6-1 may not have elasticity, they may pivot around the belt bar rotation shaft 6-3, and are tensioned by the elastic force of the torsion spring 6-2. In this embodiment, the top of the two side walls 6-01 of the channel housing 6-0 is also provided with additional brackets 6-4, which brackets 6-4 may be used to mount the channel housing 6-0 to the flexible strip material of the flexible drive mechanism. In this embodiment, the brackets 6-4 may also be arranged to allow the axle of the wheel 3-2 to rest on two additional brackets 6-4, the underside semicircle of the axle of the wheel 3-2 being clamped by two clamping blocks 6-1. In this embodiment, as shown in fig. 5, the traction device 2-2 may further include a pair of blocking pieces 5-2 disposed at one end of the traction device 2-2 near the exit of the security inspection channel, such that when the at least one clamping mechanism 5-1 moves toward the pair of blocking pieces 5-2, the pair of blocking pieces 5-2 respectively contact the rods 6-30 of the corresponding rod-carrying shaft 6-3 and guide the rods 6-30 to rotate, so that the rod-carrying shaft 6-3 is rotated, and the clamping blocks 6-1 release the wheels 3-2. The distance between the illustrated pair of flaps 5-2 varies in the conveying direction of the conveyor 1-2, in particular the illustrated pair of flaps 5-2 extends from a distance away from the security channel outlet towards a distance close to the security channel outlet and the distance between the illustrated pair of flaps 5-2 gradually decreases.
