[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0021] like Figure 1 , 2 As shown, the electric cantilever telescopic shelf for nuclear power in a preferred embodiment of the utility model comprises a plurality of groups of support units 1, and each group of support units 1 is distributed in the height direction.

[0022] The support unit 1 includes a plurality of fixed cantilevers 11 arranged side by side and spaced apart in the horizontal direction, a plurality of telescopic cantilevers 12 arranged side by side and spaced apart in the horizontal direction, and a driving mechanism 13. The telescopic cantilevers 12 are provided with positioning parts 121 for horizontally placing and positioning materials. The positioning parts 121 are usually recessed structures or slot structures, which can allow metal materials to be horizontally placed in the positioning parts 121 of each telescopic cantilever 12 to support the metal materials. The number of fixed cantilevers 11 and telescopic cantilevers 12 can be two or more respectively to achieve support for the materials.

[0023] The driving mechanism 13 drives the telescopic cantilever 12 to move horizontally in the length direction relative to the fixed cantilever 11, and adjusts the relative positions of the fixed cantilever 11 and the telescopic cantilever 12. When the telescopic cantilever 12 and the fixed cantilever 11 are staggered and extended, the positioning portion 121 is used for placing materials or taking materials out from the positioning portion 121. After the telescopic cantilever 12 retracts to the inner end onto the fixed cantilever 11, the placed materials are stored or reset after the materials are taken out.

[0024] The electric cantilever telescopic shelf for nuclear power drives the telescopic cantilever 12 to move horizontally through the driving mechanism 13, which can realize the electric extension and retraction of the shelf cantilever, so that the telescopic cantilever 12 can be extended for material placement or removal, which is convenient, fast, safe and stable, and overcomes the problem of difficulty in accessing ordinary shelves on the market.

[0025] The shelf also includes a support column 2 for supporting the fixed cantilever 11, and the lower end of the support column 2 is fixed to the ground by an anchor bolt. The fixed cantilever 11 can be welded to the support column 2, or can be locked to the support column 2.

[0026] The driving mechanism 13 is arranged on the supporting column 2, and can drive the telescopic cantilever 12 to move back and forth in the horizontal direction to achieve telescoping, so as to facilitate the placement or removal of materials.

[0027] The driving mechanism 13 includes a driving motor 131 and a transmission shaft 132. The transmission shaft 132 is rotatably installed. The driving motor 131 drives the transmission shaft 132 to rotate. When the transmission shaft 132 rotates, the telescopic cantilever 12 is driven to move along the length direction through the transmission structure. In this embodiment, a gear is provided on the transmission shaft 132, and the telescopic cantilever 12 is provided with a rack meshing with the gear on the transmission shaft 132. When the transmission shaft 132 rotates, the gear drives the telescopic cantilever 12 to move, thereby realizing the horizontal movement of the telescopic cantilever 12, so that the positioning part 121 can be exposed or retracted. In other embodiments, the transmission shaft 132 can also drive the telescopic cantilever 12 to move through a gear belt.

[0028] Preferably, each telescopic cantilever 12 is slidably matched with a fixed cantilever 11, which can improve the stability of the horizontal movement of the telescopic cantilever 12 and make the movement smoother.

[0029] In some embodiments, the support unit 1 further includes a limiting mechanism 14 for limiting the moving range of the telescopic cantilever 12, so that the telescopic cantilever 12 can move within a set range without colliding with other parts, thereby improving safety.

[0030] Furthermore, the limit mechanism 14 includes two limit switches 141 arranged on the fixed cantilever 11 at intervals along the length direction, and the telescopic cantilever 12 is provided with a limit portion 122 located between the two limit switches 141. When the telescopic cantilever 12 moves back and forth, it can contact the two limit switches 141 respectively. After the limit switch 141 is triggered, the operation of the driving mechanism 13 can be stopped, so that the telescopic cantilever 12 stops moving.

[0031] In this embodiment, the limit part 122 is located near the inner end of the telescopic cantilever 12. When the telescopic cantilever 12 moves to the front end, the limit part 122 touches the limit switch 141, triggering a signal to the control box, and the control box stops the motor according to the signal, thereby stopping the telescopic cantilever 12; when the telescopic cantilever 12 moves to the innermost end, the limit part 122 touches the limit switch 141, triggering a signal to the control box, and the control box stops the motor according to the signal, thereby stopping the telescopic cantilever 12.

[0032] In this embodiment, the limit portion 122 is located near the inner end of the telescopic cantilever 12, and when the telescopic cantilever 12 moves back and forth, it contacts the two opposite sides of the two limit switches 141 to trigger the limit switches 141. In other embodiments, the limit portion 122 may also include two, which are located at the two opposite sides of the two limit switches 141, and when the telescopic cantilever 12 moves, each limit portion 122 can contact a limit switch 141 to achieve position control of the telescopic cantilever 12.

[0033] The electric cantilever telescopic shelf for nuclear power can realize the electric extension and retraction of the shelf cantilever, thereby realizing the direct lifting and retrieval of materials without the risk of crooked or slanted lifting, and improving the inherent safety of nuclear power material lifting. It is necessary to design a cantilever telescopic shelf with electric function made of metal materials specially used for nuclear power.

[0034] It can be understood that the above-mentioned technical features can be used in any combination without limitation.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
