Description

Technical Field

[0001] The present invention relates to the technical field of security inspection equipment, and in particular to a high-speed intelligent security inspection machine performance testing tool. Background Art

[0002] Existing security inspection machines use rolling conveyor belts as transmission devices, which cannot effectively brake the inspection objects placed on them. When the transmission speed is fast, the inspection objects cannot be braked in time after passing through the security inspection machine, which can easily cause the inspection objects to fly out of the conveyor belt or be damaged. In order to avoid the problem of the inspection objects not being able to be braked in time, some security inspection machines have begun to use transmission devices that can control the acceleration and deceleration of the inspection objects, such as screw drives or chain drives.

[0003] Although the lead screw drive or chain drive can effectively solve the problem of acceleration and deceleration of the detected object, this technology also has obvious shortcomings. First, the lead screw drive has a long acceleration and deceleration distance, which increases the overall size of the equipment and is not convenient for flexible use. The chain drive has poor operating stability and cannot pass through the scanning section of the security inspection machine at a uniform speed, affecting the equipment recognition effect; secondly, the lead screw and chain are both made of metal, which will interfere with the X-ray recognition results when passing through the scanning section of the security inspection machine, affecting the recognition accuracy.

[0027] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0028] This embodiment provides a high-speed intelligent security inspection machine performance testing tool, such as Figure 1-3 As shown, it includes an adjustable support mechanism 101, an adjustable rotating mechanism 107, a motor and a transmission device 102, an expandable guide rail mechanism 103, a pulley and a tensioning device 104, a transmission platform 105 and an electric control cabinet 106.

[0029] In this embodiment, the total length of the detection tooling is 6553 mm, the maximum width is 1605 mm, the maximum height is 1493 mm, and the maximum width of the passage into the security inspection machine is 450 mm.

[0030] like Figure 4 As shown, the adjustable support mechanism includes a suction cup foot 1, an aluminum alloy profile bracket 2 and a height-adjustable crossbeam 3.

[0031] The bottom of each support leg 21 of the aluminum alloy profile bracket 2 is provided with a suction cup foot 1, which is used to strengthen the firmness of the aluminum alloy profile bracket when it is supported on the ground to prevent excessive inertia from causing displacement and causing equipment damage when a large load moves at high speed.

[0032] A crossbeam 3 is provided between the two supporting legs 21 on the front side of the aluminum alloy profile bracket 2 and between the two supporting legs 21 on the rear side of the aluminum alloy profile bracket 2. Each crossbeam 3 can move up and down along the two supporting legs 21 connected thereto and be fixed at any height.

[0033] More specifically, each support leg 21 of the aluminum alloy profile bracket 2 is provided with a vertically extending groove 22 on its inner side, and a slider 4 with bolts is installed at both ends of each crossbeam 3. The slider 4 can be slidably assembled in the groove 22 of the support leg 21 at the corresponding position, and can be fixed at any position on the support leg 21 by tightening the bolts. When the bolts are loosened, the crossbeam can slide up and down along the groove using the slider. When the crossbeam is to be fixed at a certain position, the bolts are tightened so that the bolts are fastened to the support leg, thereby fixing the slider and the bracket. The height adjustment range of the crossbeam is 30cm-120cm from the ground.

[0034] like Figure 5As shown, an adjustable rotating mechanism is provided on both sides of the bracket, and the adjustable rotating mechanism includes a steering wheel 5, a rotating shaft support seat 10, a rotating shaft, an angle scale 6, an angle lock, a rotation angle pointer 7, a load-enhanced bracket 8 and a guide rail support platform 9. Among them, the load-enhanced bracket 8 and the rotation angle pointer 7 are both installed on the guide rail support platform 9, the steering wheel 5 is connected to the guide rail support platform 9 through a rotating shaft, the rotating shaft is rotatably arranged in the rotating shaft support seat 10, and the angle scale 6 is fixed to the rotating shaft support seat 10; the rotating shaft support seat 10 is installed on the front crossbeam of the adjustable support mechanism, and the load-enhanced bracket 8 is connected to the rear crossbeam of the adjustable support mechanism through a movable latch; the rotation angle pointer 7 and the angle scale 6 can be locked by an angle lock. In this embodiment, the angle lock position bolt. When in use, open the angle lock and slowly turn the steering wheel 5, the guide rail support platform 9 rotates through the shaft, and the rotation angle pointer 7 also rotates. When the angle scale 6 moves to the specified scale, the angle lock is locked to complete the angle adjustment of the motor and the transmission device 102. The adjustable rotation mechanism can achieve any angle adjustment between -90° and 45°. The main purpose of the load-enhanced bracket is to strengthen the motor and the transmission device 102 in high-strength, large-load, and long-term operation scenarios to prevent deformation and damage to the equipment.

[0035] The motor and transmission device include a servo motor, a reduction mechanism, a synchronous belt 11, a driving wheel and a driven wheel 12; on the adjustable rotating mechanism on one side, the servo motor and the reduction mechanism are fixed to the guide rail support platform 9 through a motor fixing bracket and a reduction mechanism fixing bracket respectively; the driving wheel is connected to the servo motor through the reduction mechanism, and the two ends of the synchronous belt 11 are respectively wound around the driving wheel and the driven wheel 12. The servo motor provides power, and the reduction mechanism converts the power of the servo motor into power suitable for the synchronous belt 11 according to the designed transmission ratio. When the angle of the guide rail support platform changes, the servo motor and the reduction mechanism follow the change. The synchronous belt transmits the power of the servo motor to the transmission platform, driving the transmission platform to accelerate, decelerate and move at a uniform speed.

[0036] like Figure 6As shown, the expandable guide rail mechanism includes a segmented carbon fiber composite guide rail, a receiving tray 15 and a deceleration damper 16; the segmented carbon fiber composite guide rail includes a carbon fiber composite long tube 13 and two carbon fiber composite short tubes 14, the two carbon fiber composite short tubes 14 are respectively fixed on the guide rail support platform 9 of the adjustable rotating mechanism on both sides through the guide rail fixing bracket, and the two ends of the carbon fiber composite long tube 13 are respectively connected to the two carbon fiber composite short tubes 14 through the receiving tray 15, and the carbon fiber composite short tube 14 is a part that passes through the security inspection machine channel. The carbon fiber composite short tube 14 is provided with markings of the starting position, the end position and the middle position of the uniform transmission section. When in use, it is necessary to align the marking of the middle position of the uniform transmission section with the position of the X-ray scanning section in the security inspection machine channel. The deceleration damper 16 is installed on the guide rail fixing bracket. In the scenario of high-speed operation with a large load, when the design inertia is exceeded and the deceleration distance is too short, it is used for passive braking, which can effectively prevent equipment damage and other dangerous situations outside the design scenario.

[0037] The pulley and tensioning device include a mechanical tensioning device 17; the driven wheel 12 is connected to the mechanical tensioning device 17, and the mechanical tensioning device 17 is installed on the guide rail support platform 9 of the adjustable rotating mechanism on the other side. The driven wheel 12 is rotatably connected to the mechanical tensioning device 17, and the mechanical tensioning device 17 is used to adjust the forward and backward movement of the driven wheel 12 along the extending direction of the synchronous belt 11. The mechanical tensioning device can adjust the forward and backward position of the driven wheel on the guide rail support platform, and then adjust the tightness of the synchronous belt, so that the synchronous belt is kept in the best transmission state.

[0038] like Figure 7 As shown, the transmission platform includes a loading tray 18, a composite material bolt 19, a ceramic bearing, a composite material pulley 20, a composite material synchronous belt pressure plate 23, a composite material anti-collision baffle 24 and a non-metallic binding belt; the loading tray 18 is made of POM plastic material, which is provided with a fixing hole and is used when the non-metallic binding belt fixes the detection body; a ceramic bearing is provided inside the composite material pulley 20, and the composite material pulley 20 is rotatably connected to the lower end of the composite material bolt 19 through the ceramic bearing, and the upper end of the composite material bolt 19 is connected to the bottom of the loading tray 6; the loading tray 18 is placed on the carbon fiber composite material long tube 13, and the composite material pulley 20 can slide on the carbon fiber composite material long tube 13; the composite material pulley 20 is connected to the synchronous belt 11 through the composite material synchronous belt pressure plate 23, and is driven by the synchronous belt 11 to move on the carbon fiber composite material long tube 13.

[0039] The electric control cabinet is composed of a cabinet body, a cabinet door, a touch LCD screen, a button panel, a servo motor driver, a PLC host, a power controller, relays, a brake resistor, a circuit breaker, terminals, etc. The main function of the electric control cabinet is to control the detection tooling to automatically complete the entire process of acceleration, uniform speed, deceleration, and transmission of the detection object back to the starting position after stopping according to the given detection speed.

[0040] The detection fixture of the present embodiment was tested. The standard test body was driven by a synchronous belt to accelerate to 3.5m / s, and then passed through the security inspection equipment at a uniform speed for security inspection performance testing. The uniform motion distance was 1m. After the standard test body ran out of the security inspection machine as a whole, the servo motor controlled the speed to decelerate to a standstill. The results showed that the servo motor controlled the acceleration, uniform speed (detection), and deceleration processes of the detection body, which was easy to control; the acceleration and deceleration distances of the detection equipment were short, and the length of the entire equipment was less than 7m; the test system was easy to install, disassemble and transport.

It has a stable structure and the operation process is precise and controllable.
