[0032] Please also read Figure 1 and Figure 2 Now, a sealed transport channel steering transport device provided by the utility model is described.

[0033] A sealed transport channel steering transport device comprises a four-way channel 1, a rotating magnetic field generator 2, a rotating sling mechanism 3, a rotating magnetic field secondary plate and an upper turntable 4. The rotating magnetic field generator 2 is arranged above the outside of the four-way channel 1, and the rotating magnetic field generator 2 is used to generate a rotating magnetic field; the rotating sling mechanism 3 is rotatably arranged inside the four-way channel 1, and the top of the rotating sling mechanism 3 is spaced from the inner top of the four-way channel 1; the rotating magnetic field secondary plate is arranged on the top of the rotating sling mechanism 3; the upper turntable 4 is rotatably arranged at the bottom inside the four-way channel 1, and the upper end surface of the upper turntable 4 is connected to the rotating sling mechanism 3, and the upper turntable 4 rotates around the vertical central axis.

[0034] The utility model provides a sealed transport channel steering transport device. Compared with the prior art, the utility model includes a four-way channel 1, a rotating magnetic field generator 2, a rotating sling mechanism 3, a rotating magnetic field secondary plate and an upper turntable 4. When the radioactive material is transported to the position of the turntable, the rotating magnetic field generator 2 is started to form a rotating magnetic field; the rotating sling mechanism 3 is driven to rotate, and since the upper turntable 4 is connected to the rotating sling mechanism 3, the upper turntable 4 is driven to rotate at the same time; the upper turntable 4 rotates around the central axis under the action of the rotating magnetic field, so as to solve the technical problems of cumbersome steering operation and complex structural design of nuclear materials in a confined space in the prior art.

[0035] In some embodiments, the four-way channel 1 may adopt a structure as shown in the figure. Referring to the figure, the four-way channel 1 includes a channel body 11 and a plurality of brackets 12, and the plurality of brackets 12 are arranged at the lower part of the channel body 11. By arranging a plurality of brackets 12 at the lower part of the channel body 11, the height of the channel body 11 is always kept consistent.

[0036] On the basis of the above embodiment, it also includes a control unit, which is electrically connected to the rotating magnetic field generator 2. The control unit is started. Since the control unit is electrically connected to the rotating magnetic field generator 2, the rotating magnetic field generator 2 can be remotely controlled by remotely controlling the control unit, thereby improving the automation of the equipment.

[0037] In some embodiments, the rotating sling mechanism 3 adopts a structure as shown in the figure. Referring to the figure, the rotating sling mechanism 3 adopts a hollow structure, which not only facilitates the radioactive materials to enter and exit the upper turntable 4, but also reduces its own weight and reduces the rotation power of the rotating magnetic field generator 2.

[0038] In some embodiments, the bracket 12 is a rod-shaped structure that is telescopic along the length direction. The height of the center line of the channel body 11 can be adjusted by adjusting the length of the bracket 12 to ensure that the center line of the channel body 11 always remains horizontal.

[0039] For further information, see Figure 4 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 channel body 11; a plurality of positioning holes 1221 are arranged at one end of the second branch pipe 122, and the positioning holes 1221 are arranged linearly and longitudinally along the tube body of the second branch pipe 122; the bolt 123 is installed in the limiting hole and plugged into the positioning hole 1221 to drive the first branch pipe 121 to move relative to the second branch pipe 122.

[0040] When the length of the bracket 12 needs to be adjusted, the worker removes the bolt 123 from the positioning hole 1221 and adjusts the relative position relationship between 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 into place, the worker inserts the bolt 123 into the positioning 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 actual conditions.

[0041] Furthermore, an adjusting foot 13 is provided at the bottom of the bracket 12. Since the foundation surface of the tunnel itself is not very accurate, the adjusting foot 13 can be provided to fine-tune the bracket 12 so that the center line of the channel body 11 is always kept within the allowable range.

[0042] Furthermore, the bottom surface of the adjusting foot 13 is provided with anti-skid grooves to increase the adhesion between the adjusting foot 13 and the tunnel.

[0043] Furthermore, the cross section of the channel body 11 is rectangular, which is convenient for the transportation of radioactive materials and the processing and manufacturing of the channel body 11 .

[0044] Furthermore, the four-way channel 1 also includes:

[0045] A lower turntable 5 is disposed at the bottom outside the four-way passage 1, and the lower turntable 5 is disposed corresponding to the upper turntable 4;

[0046] A driving motor, the power output end of which is rotatably connected to the lower turntable 5, and the driving motor drives the lower turntable 5 and the upper turntable 4 to rotate synchronously;

[0047] Wherein, the driving motor is electrically connected to the control unit.

[0048] The transport trolley 7 is arranged to move in the four-way channel 1. The RGV trolley 6 is provided with a traveling wave magnetic field generator. The transport trolley 7 is provided with a traveling wave magnetic field secondary plate. When the RGV trolley 6 moves outside the four-way channel 1, the traveling wave magnetic field generator drives the traveling wave magnetic field secondary plate to move, thereby driving the transport trolley 7 to move. When the transport trolley 7 travels to the position of the upper turntable 4, when the RGV trolley 6 travels to the lower turntable 5, the rotating magnetic field generator 2 drives the upper turntable 4 to rotate, while the control unit controls the drive motor to move, driving the lower turntable 5 to rotate synchronously. When the turn is completed, the RGV trolley 6 is started, and the RGV trolley 6 drives the transport trolley 7 to continue to travel in the four-way channel 1.

[0049] Furthermore, the drive motor adopts a servo motor, which has the following advantages over a stepper motor:

[0050] 1. Accuracy: It realizes closed-loop control of position, speed and torque; it overcomes the problem of stepping motor losing step;

[0051] 2. Adaptability: It has strong overload resistance and can withstand loads three times the rated torque. It is particularly suitable for occasions with instantaneous load fluctuations and requirements for rapid starting.

[0052] 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 in the protection scope of the present invention.
