When the jacking roller is at the same height as the top roller of the bottom plate, the battery can be directly pushed above the bottom plate. S3: When there is a horizontal bar on the side of the battery rack, the operator needs to move the battery body above the bottom plate into the battery rack or move the battery in the battery rack to above the bottom plate, the operator fixes the claw to the battery body, and then the operator rotates the second hand wheel to drive the second synchronous wheel to rotate, and then drives the first synchronous wheel to rotate, and then drives the worm to rotate, and then drives the worm wheel to rotate, and then drives the threaded rod to rotate. Since the threaded rod is threadedly connected to the bottom plate of the trolley, the threaded rod moves up or down when it rotates, and then drives the claw and the battery body to move up, and then the operator moves the bottom plate of the trolley forward and backward, and then moves the claw and the battery body forward and backward, and then replaces the battery body.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention adopts the method that the operator places the battery body on the guide roller surface on the top of the bottom plate.

[0024] As a technical optimization solution of the present invention, the provision of the protective cover 36 can prevent the operator from accidentally touching the first bevel gear 4 or the second bevel gear 5 and causing harm to the operator.

[0025] refer to Figure 3 and Figure 4The battery lifting mechanism 14 includes a lifting bracket 29 arranged on the back of the transfer trolley 1, and the bottom of the lifting bracket 29 is fixedly connected with moving wheels 30 on all sides. The surface of the lifting bracket 29 is hinged with a cylinder 31, and the top of the lifting bracket 29 is hinged with a connecting rod 40.

[0026] As a technical optimization scheme of the present invention, through the setting of the battery lifting mechanism 14, the height of the battery body 25 above the bottom plate 10 is different from the height of the battery body 25 above the battery shelf 12. The operator can use the battery lifting mechanism 14 to push the battery body 25 above the bottom plate 10 directly into the battery shelf 12. The operator adjusts the extension of the oil cylinder 31 to drive the mounting frame 32 to move, and the height of the mounting frame 32 increases. At this time, the connecting rod 40 rotates, and then the operator pushes the battery body 25 above the bottom plate 10 directly to the top of the mounting frame 32, and then starts the oil cylinder 31 to contract, so that the mounting frame 32 is reset, and the mounting frame 32 moves down, so that the bottom of the battery body 25 is in contact with the battery shelf 12, thereby completing the convenient movement of the battery body 25 above the bottom plate 10 to the inside of the battery shelf 12. The setting of the transition wheel 34 can play a supporting role, and the setting of the positioning block 35 can be used to fit and limit the two sides of the battery body 25.

[0030] As a technical optimization solution of the present invention, by providing the lower guide frame 38 and the upper guide frame 39 , the battery body 25 can be limited, thereby improving the stability of the battery body 25 above the bottom plate 10 .

[0031] refer to Figures 1 to 6 A battery transfer vehicle for a nuclear power plant and a transfer method thereof, comprising the following steps: S1: The operator places the battery body 25 on the surface of the guide roller 37 on the top of the bottom plate 10, and limits the battery body 25 under the limiting action of the upper guide frame 39 and the lower guide frame 38. When the operator needs to adjust the battery body 25 above the bottom plate 10 to move up and down, the operator rotates the first hand wheel to drive the first rotating shaft 2 to rotate, and then drives the two first bevel gears 4 on the surface of the first rotating shaft 2 to rotate, and then drives the second bevel gear 5 and the second rotating shaft 3 to rotate, and then drives the sprocket 7 on the surface of the second rotating shaft 3 to rotate, and then drives the chain 8 to rotate, and then drives the third rotating shaft 2 to rotate. The shaft 6 and the sprocket 7 on the surface of the third rotating shaft 6 rotate.

The operator can rotate the third hand wheel, thereby driving the screw rod 27 to rotate, and then driving the push plate 28 to move toward the back. The push plate 28 is located between the upper guide frame 39 and the lower guide frame 38. The push plate 28 can simultaneously push multiple battery bodies 25 above the bottom plate 10 to the back, thereby improving the transportation efficiency of the transport trolley 1 for the battery body 25; S2: When there is no cross bar on the side of the battery shelf, the operator needs to move the battery body 25 above the bottom plate 10 into the battery shelf 12. The operator only needs to place the lifting mechanism 14 under the battery shelf 12, and the operator adjusts the extension of the oil cylinder 31 to drive the mounting frame 32 to move, and the height of the mounting frame 32 is increased. At this time, the connecting rod 40 rotates. When the lifting roller 33 is at the same height as the top roller 37 of the bottom plate 10, the operator can rotate the third hand wheel to rotate the screw rod 27 to drive the push plate 27 to directly push the battery body 25 to the top of the mounting frame 32, and then start the oil cylinder 31 to retract, so that The mounting frame 32 is reset and moved downward, so that the bottom of the battery body 25 is in contact with the battery rack 12. When the operator needs to move the battery in the battery rack 12 to above the bottom plate 10, the operator only needs to place the lifting mechanism 14 under the battery 25 in the battery rack, and the operator adjusts the extension of the oil cylinder 31 to drive the mounting frame 32 to move, and the height of the mounting frame 32 is increased. At this time, the connecting rod 40 rotates, driving the battery 25 to rise and move forward a certain distance. When the lifting roller 33 is at the same height as the top roller 37 of the bottom plate 10, the battery 25 can be directly pushed above the bottom plate 10; S3: When there is a horizontal bar on the side of the battery rack, the operator needs to move the battery body 25 above the bottom plate 10 into the battery rack 12 or move the battery in the battery rack 12 to the top of the bottom plate 10, the operator fixes the claw 19 to the battery body 25, and then the operator rotates the second hand wheel to drive the second synchronous wheel to rotate, and then drives the first synchronous wheel 23 to rotate, and then drives the worm 22 to rotate, and then drives the worm wheel to rotate, and then drives the threaded rod 20 to rotate. Since the threaded rod 20 is threadedly connected to the trolley bottom plate 17, the threaded rod 20 moves up or down when it rotates, and then drives the claw 19 and the battery body 25 to move up, and then the operator moves the trolley bottom plate 17 forward and backward, and then moves the claw 19 and the battery body 25 forward and backward, and then replaces the battery body 25.

[0032] The working principle and use process of the present invention are as follows: when in use, the operator places the battery body 25 on the surface of the guide roller 37 on the top of the bottom plate 10, and limits the battery body 25 under the limiting action of the upper guide frame 39 and the lower guide frame 38. When the operator needs to adjust the battery body 25 above the bottom plate 10 to move up and down, the operator rotates the first hand wheel to drive the first rotating shaft 2 to rotate, and then drives the two first bevel gears 4 on the surface of the first rotating shaft 2 to rotate, and then drives the second bevel gear 5 and the second rotating shaft 3 to rotate, and then drives the sprocket 7 on the surface of the second rotating shaft 3 to rotate, and then drives the chain 8 The third rotating shaft 6 and the sprocket 7 on the surface of the third rotating shaft 6 are driven to rotate. When the chain 8 rotates, the lifting column 9 fixed on the surface of the chain 8 will be driven to move upward, thereby driving the bottom plate 10 to move upward, and then driving the battery body 25 above the bottom plate 10 to move upward. The operator can rotate the third hand wheel, thereby driving the screw rod 27 to rotate, and then driving the push plate 28 to move toward the back. The push plate 28 is located between the upper guide frame 39 and the lower guide frame 38. The push plate 28 can simultaneously push multiple battery bodies 25 above the bottom plate 10 to the back, thereby improving the transportation efficiency of the transfer trolley 1 for the battery body 25.

8. The method for transporting a battery transport vehicle for a nuclear power plant according to claim 7, characterized in that: The following steps are involved: S1: The operator places the battery body (25) on the surface of the guide roller (37) on the top of the bottom plate (10), and limits the battery body (25) under the limiting action of the upper guide frame (39) and the lower guide frame (38). When the operator needs to adjust the battery body (25) above the bottom plate (10) to move up and down, the operator rotates the first hand wheel to drive the first rotating shaft (2) to rotate, thereby driving the two first bevel gears (4) on the surface of the first rotating shaft (2) to rotate, thereby driving the second bevel gear (5) and the second rotating shaft (3) to rotate, thereby driving the sprocket (7) on the surface of the second rotating shaft (3) to rotate, thereby driving the chain (8) to rotate, thereby driving the third rotating shaft (6 ) and the sprocket wheel (7) on the surface of the third rotating shaft (6) rotate. When the chain (8) rotates, it drives the lifting column (9) fixed on the surface of the chain (8) to move upward, thereby driving the bottom plate (10) to move upward, thereby driving the battery body (25) above the bottom plate (10) to move upward. The operator can rotate the third hand wheel to drive the screw rod (27) to rotate, thereby driving the push plate (28) to move toward the back. The push plate (28) is located between the upper guide frame (39) and the lower guide frame (38). The push plate (28) can simultaneously push multiple battery bodies (25) above the bottom plate (10) toward the back, thereby improving the transportation efficiency of the battery body (25) of the transportation trolley (1); S2: When the battery rack has no horizontal bar on the side, and the operator needs to move the battery body (25) above the bottom plate (10) into the battery rack (12), the operator only needs to place the lifting mechanism (14) below the battery rack (12), and the operator adjusts the extension of the oil cylinder (31), thereby driving the mounting frame (32) to move, and the height of the mounting frame (32) is increased. At this time, the connecting rod (40) rotates, and when the lifting roller (33) and the top roller (37) of the bottom plate (10) are at the same height, the operator can rotate the third hand wheel to drive the push plate (27) to directly push the battery body (25) to the top of the mounting frame (32), and then start the oil cylinder (31) to retract, so that the mounting frame (32) can be moved. The mounting frame (32) is reset and the mounting frame (32) is moved downward, so that the bottom of the battery body (25) is in contact with the battery shelf (12). When the operator needs to move the battery in the battery shelf (12) to above the bottom plate (10), the operator only needs to place the lifting mechanism (14) below the battery (25) in the battery shelf. The operator adjusts the extension of the oil cylinder (31), thereby driving the mounting frame (32) to move, and the height of the mounting frame (32) is increased. At this time, the connecting rod (40) rotates, driving the battery (25) to rise and move forward a certain distance. When the lifting roller (33) and the top roller (37) of the bottom plate (10) are at the same height, the battery (25) can be directly pushed above the bottom plate (10); S3: When there is a horizontal bar on the side of the battery shelf, the operator needs to move the battery body (25) above the bottom plate (10) into the battery shelf (12) or move the battery in the battery shelf (12) to above the bottom plate (10). The operator fixes the claw (19) and the battery body (25). The operator then rotates the second hand wheel to drive the second synchronous wheel to rotate, thereby driving the first synchronous wheel (23) to rotate, thereby driving the worm (22) to rotate, thereby driving the worm wheel to rotate, thereby driving the threaded rod (20) to rotate. Since the threaded rod (20) is threadedly connected to the trolley bottom plate (17), when the threaded rod (20) rotates, the threaded rod (20) moves up or down, thereby driving the claw (19) and the battery body (25) to move up. The operator then moves the trolley bottom plate (17) forward and backward, thereby moving the claw (19) and the battery body (25) forward and backward, thereby replacing the battery body (25).
