Description

Technical Field

[0001] This invention belongs to the field of nuclear technology, and specifically relates to a sealed transport channel. Background Technology

[0002] In the field of sealed transport technology for radioactive materials, radioactive materials pose a significant hazard and must be transported in sealed transport channels. During transport, there are issues of interference between channels in different directions and the steering of transport vehicles. Due to the sealing issues involved, the steering structure design of RGV trolleys is relatively complex, the steering operation is cumbersome, and in order to ensure that the power structure reduces the impact of radiation, the power is mostly located outside the channel, resulting in difficulties in multi-directional material transfer and poor overall sealing. Summary of the Invention

[0003] This invention provides a sealed transfer channel, which aims to solve the technical problems of cumbersome turning operations and the inability to seal the transportation process in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a sealed transfer channel, comprising:

[0005] A first horizontal passage is provided with a first external track, which is located below the first horizontal passage.

[0006] The second horizontal channel has a second external track, which is located below the second horizontal channel, and the first horizontal channel and the central axis of the second horizontal channel are set at an angle.

[0007] A rotating unit is located at the intersection of the central axes of the first horizontal channel and the second horizontal channel. The rotating unit includes a steering channel, a rotating magnetic field generator, a rotating lifting mechanism, a first stage plate, and an upper turntable. The steering channel is connected to both the first and second horizontal channels. The rotating magnetic field generator is located above and outside the steering channel. The rotating lifting mechanism is rotatably located inside the steering channel, with its top spaced apart from the inner top of the steering channel. The first stage plate is located on top of the rotating lifting mechanism. The upper turntable is rotatably located at the bottom of the steering channel, with its upper end face connected to the rotating lifting mechanism, and the upper turntable rotates circumferentially along the vertical central axis.

[0008] The steering unit includes a lower turntable and a drive motor. The power output end of the drive motor is rotatably connected to the lower turntable. The lower turntable is rotatably located below the steering channel, and the lower turntable is correspondingly arranged with the upper turntable. The central axis of the lower turntable is collinear with the central axis of the upper turntable.

[0009] A non-powered trolley with a secondary stage plate at the bottom;

[0010] The RGV trolley is equipped with a traveling magnetic field generator;

[0011] The RGV trolley moves on the first external track or the second external track, and the RGV trolley drives the unpowered trolley to move within the first horizontal channel or the second horizontal channel.

[0012] In one possible implementation, multiple supports are provided below both the first horizontal channel and the second horizontal channel.

[0013] In one possible implementation, a control unit is also included, which is electrically connected to the drive motor, the rotating magnetic field generator, the RGV trolley, and the traveling magnetic field generator.

[0014] In one possible implementation, the rotating lifting mechanism is a hollow structure.

[0015] In one possible implementation, the support is a rod-shaped structure that extends and retracts along its length.

[0016] In one possible implementation, the support has adjustable feet at the bottom.

[0017] In one possible implementation, the support includes:

[0018] The first branch pipe is set vertically, with a limiting hole at one end and the other end connected to the first horizontal channel and the second horizontal channel;

[0019] The second branch pipe has multiple locking holes at one end, which are arranged longitudinally and linearly along the pipe body of the second branch pipe; and

[0020] A bolt is installed in the limiting hole and inserted into the locking hole to drive the first branch pipe to move relative to the second branch pipe.

[0021] In one possible implementation, the bottom surface of the adjustable support foot is provided with anti-slip texture.

[0022] In one possible implementation, the cross-sections of the first horizontal channel and the second horizontal channel are rectangular.

[0023] In one possible implementation, the drive motor is a servo motor.

[0024] The beneficial effects of the sealed transfer channel provided by this invention are as follows: Compared with the prior art, this invention includes a first horizontal channel, a second horizontal channel, a rotating unit, a steering unit, a non-powered trolley, and an RGV trolley. First, the RGV trolley and the traveling magnetic field generator are started. The traveling magnetic field generator forms a traveling wave magnetic field that is magnetically connected to the second stage plate. While the RGV trolley moves on the first external track, it simultaneously drives the non-powered trolley to move within the first horizontal channel. When the RGV trolley moves to the lower turntable, the non-powered trolley synchronously moves to the upper turntable. At this point, the traveling magnetic field generator is turned off, and the rotating magnetic field generator is started to form a rotating magnetic field. The rotating magnetic field generator and the first stage plate form a rotating magnetic field, which drives the rotating lifting mechanism to rotate. Since the upper turntable is connected to the rotating lifting mechanism, it also drives the upper turntable to rotate. Under the action of the rotating magnetic field, the upper turntable rotates around the central axis. At the same time, the drive motor drives the lower turntable to move in the same direction and frequency. When the rotating unit finishes turning, the rotating unit docks with the second horizontal channel, and the lower turntable docks with the second external track. Finally, the RGV trolley and the traveling magnetic field generator are started and the rotating magnetic field generator is turned off. The RGV trolley continues to drive the unpowered trolley to move in the second horizontal channel, so as to solve the technical problems of cumbersome turning operation and inability to seal the transportation process in the prior art.

[0035] Please refer to the following: Figure 1 and Figure 2 The present invention will now describe a sealed transfer channel.

[0036] A sealed transfer channel includes a first horizontal channel 1, a second horizontal channel 2, a rotating unit, a steering unit, a non-powered trolley 8, and an RGV trolley 9. A first external track is provided outside the first horizontal channel 1, and the first external track is located below the first horizontal channel 1.

[0037] The second horizontal channel 2 is provided with a second external track, which is located below the second horizontal channel 2, and the central axis of the first horizontal channel 1 and the second horizontal channel 2 are set at an angle.

[0038] A rotating unit is located at the intersection of the central axes of the first horizontal channel 1 and the second horizontal channel 2. The rotating unit includes a turning channel 3, a rotating magnetic field generator 4, a rotating lifting mechanism 5, a first stage plate, and an upper turntable 6. The turning channel 3 is connected to both the first horizontal channel 1 and the second horizontal channel 2. The rotating magnetic field generator 4 is located above the outside of the turning channel 3. The rotating lifting mechanism 5 is rotatably located inside the turning channel 3, with its top spaced apart from the inner top of the turning channel 3. The first stage plate is located on top of the rotating lifting mechanism 5. The upper turntable 6 is rotatably located at the bottom inside the turning channel 3, with its upper end face connected to the rotating lifting mechanism 5, and the upper turntable 6 rotates circumferentially along the vertical central axis.

[0039] The steering unit includes a lower turntable 7 and a drive motor. The power output end of the drive motor is rotatably connected to the lower turntable 7. The lower turntable 7 is rotatably located below the steering channel 3, and the lower turntable 7 is correspondingly arranged with the upper turntable 6. The central axis of the lower turntable 7 is collinear with the central axis of the upper turntable 6. The bottom of the unpowered trolley 8 is provided with a second stage plate. The RGV trolley 9 is provided with a traveling magnetic field generator.

[0040] The RGV trolley 9 moves on the first external track or the second external track, and the RGV trolley 9 drives the unpowered trolley 8 to move within the first horizontal channel 1 or the second horizontal channel 2.

[0041] This invention provides a sealed transfer channel. Compared with the prior art, this invention includes a first horizontal channel 1, a second horizontal channel 2, a rotating unit, a steering unit, a non-powered trolley 8, and an RGV trolley 9. First, the RGV trolley 9 and the traveling magnetic field generator are activated. The traveling magnetic field generator generates a traveling wave magnetic field that is magnetically connected to the second stage plate. While the RGV trolley 9 moves on the first external track, it simultaneously drives the non-powered trolley 8 to move within the first horizontal channel 1. When the RGV trolley 9 moves onto the lower turntable 7, the non-powered trolley 8 simultaneously moves onto the upper turntable 6. At this time, the traveling magnetic field generator is turned off, and the rotating magnetic field generator 4 is started to form a rotating magnetic field. The rotating magnetic field generator 4 and the first stage plate form a rotating magnetic field, which drives the rotating lifting mechanism 5 to rotate. Since the upper turntable 6 is connected to the rotating lifting mechanism 5, it also drives the upper turntable 6 to rotate. Under the action of the rotating magnetic field, the upper turntable 6 rotates around the central axis. At the same time, the drive motor drives the lower turntable 7 to move in the same direction and frequency. When the rotating unit finishes turning, the rotating unit docks with the second horizontal channel 2, and the lower turntable 7 docks with the second external track. Finally, the RGV trolley 9 and the traveling magnetic field generator are started and the rotating magnetic field generator 4 is turned off. The RGV trolley 9 continues to drive the unpowered trolley 8 to move in the second horizontal channel 2, so as to solve the technical problems of cumbersome turning operation and inability to seal the transportation process in the prior art.

[0042] In some embodiments, the four-way channel 1 described above can adopt the structure shown in the figure. See also Figure 1 Multiple supports 12 are provided below both the first horizontal channel 1 and the second horizontal channel 2. By providing multiple supports 12, the height of the first horizontal channel 1 and the second horizontal channel 2 is always kept consistent.

[0043] Based on the above embodiments, a control unit is also included. The control unit is electrically connected to the drive motor, the rotating magnetic field generator 4, the RGV trolley 9, and the traveling magnetic field generator. By remotely controlling the control unit, the opening or closing of the electrical connections of the drive motor, the rotating magnetic field generator 4, the RGV trolley 9, and the traveling magnetic field generator can be realized, thereby improving the automation of the equipment.

[0044] In some embodiments, the aforementioned rotating lifting mechanism 5 adopts, for example... Figure 2 The structure shown. See also Figure 2 The rotating lifting mechanism 5 adopts a hollow structure, which not only facilitates the entry and exit of radioactive materials on the upper turntable 6, but also reduces its own weight and reduces the rotation power of the rotating magnetic field generator 4.

[0045] In some embodiments, the aforementioned support 12 is a rod-shaped structure that extends and retracts along its length. By adjusting the length of the support 12, the height of the center lines of the first horizontal channel 1 and the second horizontal channel 2 is adjusted to ensure that the center lines of the first horizontal channel 1 and the second horizontal channel 2 are always kept on the same horizontal line, thus ensuring the stability of the unpowered trolley 8 during transportation.

[0046] Further, see Figure 3 The bracket 12 includes a first branch pipe 121, a second branch pipe 122, and a bolt 123. The first branch pipe 121 is vertically arranged, with a limiting hole at one end and the other end connected to the first horizontal channel 1 and the second horizontal channel 2. The second branch pipe 122 has multiple locking holes 1221 at one end, which are arranged longitudinally and linearly along the pipe body of the second branch pipe 122. The bolt 123 is installed in the limiting hole and inserted into the locking hole 1221 to drive the first branch pipe 121 to move relative to the second branch pipe 122.

[0047] When the length of the bracket 12 needs to be adjusted, the worker removes the bolt 123 from the locking hole 1221 and adjusts the relative position of the first branch pipe 121 and the second branch pipe 122. When the positions of the first branch pipe 121 and the second branch pipe 122 are adjusted to the correct position, the worker inserts the bolt 123 into the locking hole 1221 and installs it in the limiting hole to fix the first branch pipe 121 and the second branch pipe 122, so that the worker can adjust the length of the bracket 12 according to the actual situation.

[0048] Furthermore, the bottom of the support 12 is provided with an adjustable foot 13. Since the accuracy of the tunnel foundation surface is not high, the adjustable foot 13 can be used to fine-tune the support 12 so that the center lines of the first horizontal channel 1 and the second horizontal channel 2 are always kept within the allowable range.

[0049] Furthermore, the bottom surface of the adjustable foot 13 is provided with anti-slip texture to increase the adhesion between the adjustable foot 13 and the tunnel.

[0050] Furthermore, the cross-sections of the first horizontal channel 1 and the second horizontal channel 2 are rectangular, which facilitates the transportation of radioactive materials and the processing and fabrication of the first horizontal channel 1 and the second horizontal channel 2.

[0051] Furthermore, the drive motor is a servo motor, which has the following advantages over stepper motors:

[0052] 1. Precision: It achieves closed-loop control of position, speed, and torque; overcoming the problem of stepper motor step loss;

[0053] 2. Speed: Excellent high-speed performance; the rated speed can generally reach 2000-3000 rpm.

[0054] 3. Adaptability: It has strong overload resistance and can withstand loads three times the rated torque, making it particularly suitable for occasions with instantaneous load fluctuations and requirements for rapid start-up.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
