Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] like Figure 1-5 As shown, the present invention provides a device for transporting a shielding container for a target after irradiation, comprising: a transport trolley assembly and a hot chamber matching roller conveyor assembly, wherein the hot chamber matching roller conveyor assembly works in conjunction with the transport trolley to carry and transport the shielding container.

[0025] The transfer trolley assembly includes: the transfer trolley body, a shielding isolation plate 1, a guiding and positioning mechanism, a vehicle-mounted electric roller conveyor 3, a limit stop bar 4, a control power supply box 5, a wheel system assembly, and a transfer bracket 14; the hot chamber matching roller conveyor assembly includes: a stop cylinder 8, a pneumatic clamp 9, a position switch 10, a heavy-duty clamping cylinder 11, an internal roller conveyor 12, and a transition roller conveyor 17. The guiding and positioning mechanism includes guide positioning holes 2 and guide positioning pins 13. The wheel system assembly includes directional wheels 6 and omnidirectional wheels 7.

[0026] like Figure 1 As shown, the transfer trolley body is equipped with a vehicle-mounted electric roller conveyor 3, which is mounted on the transfer trolley body via a vehicle-mounted electric roller conveyor mounting bracket.

[0027] The transfer trolley body is equipped with a shielding isolation plate 1, which is located on the outer periphery of the vehicle-mounted electric roller conveyor 3. The shielding isolation plate 1 is set along three continuous edges other than the front end of the transfer trolley body, and an opening for transferring the shielding container is formed at the front end of the transfer trolley body. The shielding isolation plate 1 is made of 40mm thick Q235B isolation plate, which can fully protect the transfer operators and reduce the radiation dose to the personnel.

[0028] The front end of the transfer trolley body is provided with a guide positioning hole 2. A guide positioning pin 13 is installed on the lower structural component 18 of the side shielding door of the hot chamber. The side of the lower structural component 18 away from the guide positioning pin 13 is installed on the hot chamber shielding plate. The outer edge of the lower structural component 18 is flush with the side shielding door. The upper part is the side shielding door guide rail. The side shielding door is arranged above the lower structural component 18. Figure 6 As shown, the position and size of the guide positioning hole 2 match the guide positioning pin 13 installed on the hot chamber. When the transfer trolley assembly docks with the hot chamber, the guide positioning pin 13 is inserted into the guide positioning hole 2. Through the cooperation of the guide positioning hole 2 and the guide positioning pin 13, the guide positioning of the transfer trolley assembly is achieved, ensuring accurate positioning and docking between the vehicle-mounted electric roller conveyor 3 and the internal roller conveyor 12 of the chamber. The docking status of the transfer trolley with the hot chamber in the working state is as follows: Figure 7 As shown. The end of the vehicle-mounted electric roller conveyor mounting bracket near the front end of the transfer trolley body is equipped with a limit stop 4. The limit stop 4 is used to limit the shielding container and prevent the shielding container from moving on the vehicle-mounted electric roller conveyor 3 during transportation.

[0029] In one specific embodiment, the number of limit bars 4 provided on the vehicle-mounted electric roller conveyor mounting bracket is one.

[0030] In the specific implementation process, the shielding container is limited by rotating the limit stop 4 to the horizontal position, and the shielding container is transferred by rotating the limit stop 4 to the vertical position.

[0031] The transfer trolley is equipped with a control power supply box 5, which is connected to the onboard electric roller conveyor 3. The control power supply box 5 is used for powering and controlling the onboard electric roller conveyor 3, enabling it to stop, move forward, and reverse. The control power supply 5 is designed with a pluggable power interface, which connects to the reserved power interface in the hot chamber to draw power for the onboard electric roller conveyor 3.

[0032] In one specific embodiment, the control power supply box 5 is mounted on the shielding isolation plate 1, such as... Figure 2 As shown.

[0033] The bottom of the transfer trolley is equipped with directional wheels 6 and omnidirectional wheels 7. The two directional wheels 6 are symmetrically installed at the front end of the bottom of the transfer trolley, and the two omnidirectional wheels 7 are symmetrically installed at the rear end of the bottom of the transfer trolley. The directional wheels 6 and omnidirectional wheels 7 ensure the small turning radius, operability and stability of the transfer trolley during operation.

[0034] In practice, the omnidirectional wheel 7 also has a brake self-locking function, which is used to stop the transfer trolley and keep it in the stopped position.

[0035] The vehicle-mounted electric roller conveyor 3 is equipped with a transfer bracket 14, which is detachably connected to the vehicle-mounted electric roller conveyor 3. The shielding container is placed on the transfer bracket 14. The transfer bracket 14 is used to support and position the shielding container and to isolate it from the vehicle-mounted electric roller conveyor 3, so as to avoid direct contact and contamination between the vehicle-mounted electric roller conveyor 3 and the shielding container.

[0036] The transfer tray 14 can be designed in various structural shapes to match a variety of shielding containers.

[0037] In one specific implementation, such as Figure 5 As shown, the transfer bracket 14 includes a detachable lifting lug 15 and an emergency towing hook 16. The detachable lifting lug 15 is provided on the transfer bracket 14 and is used to lift the transfer bracket 14 onto the vehicle-mounted electric roller conveyor 3 by a lifting device. The rear end of the transfer bracket 14 is provided with an emergency towing hook 16, which is used to deal with the transfer operation of the shielded container under abnormal working conditions such as power failure and roller conveyor mechanical failure.

[0038] When the transfer bracket 14 is hoisted onto the vehicle-mounted electric roller conveyor 3, the front end of the transfer bracket 14 is on the same side as the front end of the transfer trolley body.

[0039] Figure 5 The transfer tray 14 shown is one type, and its specific structural shape can be adapted to the shielding container.

[0040] like Figure 3 As shown, the internal roller conveyor 12 of the chamber is installed on the bottom layer of the hot chamber through the internal roller conveyor mounting bracket. The internal roller conveyor mounting bracket is fixedly connected to the bottom plate of the hot chamber by welding. The position and size of the vehicle-mounted electric roller conveyor 3 are matched with the internal roller conveyor 12 of the chamber. The internal roller conveyor 12 of the chamber and the vehicle-mounted electric roller conveyor 3 cooperate to push the shielding container between the transfer trolley and the hot chamber through the rotation friction of the roller conveyor, which can complete the transfer of the shielding container in and out.

[0041] like Figure 7 As shown, when the transfer trolley assembly docks with the hot chamber, there is a gap between the vehicle-mounted electric roller conveyor 3 and the internal roller conveyor 12 of the chamber, consisting of a side shielding door and a hot chamber shielding plate. To effectively ensure the transfer stability of the shielded container, a transition roller conveyor 17 is provided on the hot chamber shielding plate for supporting and transferring the shielded container. The transition roller conveyor 17 is a non-powered mechanism that only supports and transfers the shielded container and does not provide transmission power.

[0042] A stop cylinder 8 is installed at the end of the roller conveyor mounting bracket inside the chamber, away from the transfer trolley assembly. The stop cylinder 8 is connected to the roller conveyor mounting bracket inside the chamber by bolts. The stop cylinder 8 is used to buffer and position the shielding container entering the hot chamber, reducing the impact of the large shielding container on the roller conveyor mounting bracket inside the chamber. By limiting the stop cylinder 8, the shielding container is stopped at the designated position, that is, the shielding container reaches the designated position, providing precise positioning for the shielding container.

[0043] like Figure 3 As shown, a pneumatic clamp 9 is installed at the end of the roller conveyor mounting bracket inside the box, away from the transfer trolley assembly. The pneumatic clamp 9 is used to press and clamp after the shielding container is in place, to longitudinally position the shielding container and prevent it from moving on the roller conveyor.

[0044] like Figure 3 As shown, a powerful clamping cylinder 11 is installed at the middle position of the roller conveyor mounting bracket inside the chamber. The powerful clamping cylinder 11 is used to press and clamp after the shielding container is in place, and to perform lateral positioning of the shielding container.

[0045] A position switch 10 is installed on one side of the roller conveyor mounting bracket inside the chamber. The position switch 10 is used to detect the position of the shielded container and provide a container position feedback signal.

[0046] The hot chamber roller conveyor assembly also includes a PLC controller, which is connected to a position switch 10. The position switch 10 sends a container position feedback signal to the PLC controller. Based on the container position feedback signal, the PLC controller generates action commands to control the operation of the internal roller conveyor 12, pneumatic clamp 9, and heavy-duty clamping cylinder 11, thereby enabling the internal roller conveyor 12 to stop and rotate (including forward and reverse rotation), the pneumatic clamp 9 to clamp and release, and the heavy-duty clamping cylinder 11 to clamp and release.

[0047] In the specific implementation process, the stop cylinder 8 works in conjunction with the position switch 10. When the shielding container reaches the designated position after being limited by the stop cylinder 8, the position switch 10 detects that the shielding container has reached the designated position, generates a container position feedback signal, and sends the container position feedback signal to the PLC controller. Based on the container position feedback signal, the PLC controller generates a stop operation command, controls the internal roller conveyor 12 of the chamber to stop, and simultaneously interlocks the pneumatic clamp 9 and the heavy-duty clamping cylinder 11 to press and clamp, performing longitudinal and lateral positioning of the shielding container. By coordinating the stop cylinder 8 and the position switch 10, the internal roller conveyor 12 of the chamber stops after the shielding container reaches the designated position, providing precise positioning for the shielding container. When it is necessary to rotate the shielding container out, the PLC controller generates a rotation operation command, controls the pneumatic clamp 9 and the heavy-duty clamping cylinder 11 to release, simultaneously opens the shielding door on the hot chamber side, and delays the rotation of the internal roller conveyor 12 of the chamber, realizing the rotation of the shielding container.

[0048] The PLC controller is connected to the control power supply box 5. The action commands generated by the PLC controller are matched with the control operations of the control power supply box 5, so that the action commands generated by the PLC controller for the internal roller conveyor 12 are consistent with the control operations of the control power supply box 5 for the vehicle-mounted electric roller conveyor 3. This enables the internal roller conveyor 12 to stop, rotate forward or reverse synchronously with the vehicle-mounted electric roller conveyor 3, thereby realizing the entry and exit operations of the shielded container.

[0049] The shielded container, supported by the transfer tray 14, is transferred together with the transfer tray 14 into the inner roller conveyor 12 of the hot chamber, avoiding direct contact and contamination with the inner roller conveyor 12, thus reducing the amount and difficulty of decontamination operations.

[0050] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. All contents not described in detail in the present invention can be derived from existing technologies.
