In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0051] This embodiment provides a nuclear-grade battery replacement device for replacing a single battery 100 of an AP1000 unit IDS. Figure 1-Figure 4 As shown, the nuclear-grade battery replacement equipment includes a mobile base 10, a slewing mechanism 20, a lifting mechanism 30, a boom mechanism 40 and a lifting mechanism 50. Among them, the slewing mechanism 20 is installed on the mobile base 10, and the execution end of the slewing mechanism 20 can rotate around the vertical axis; the lifting mechanism 30 is installed on the execution end of the slewing mechanism 20, and the execution end of the lifting mechanism 30 can be extended and retracted in the vertical direction; the boom mechanism 40 is installed on the execution end of the lifting mechanism 30, and the execution end of the boom mechanism 40 can be extended and retracted in the horizontal direction; the lifting mechanism 50 is installed on the execution end of the boom mechanism 40, and the execution end of the lifting mechanism 50 can be lifted and lowered in the vertical direction and connected to the battery 100.

[0052] Furthermore, if Figure 1-Figure 4As shown, the mobile base 10 includes a base 11, a moving wheel 12 and a leg assembly 13 installed on the base 11, and a slewing mechanism 20 is installed on the base 11. The ground contact end of the leg assembly 13 can be extended and retracted in the vertical direction, and the leg assembly 13 can be extended and retracted horizontally to retract into the base 11. The nuclear-grade battery replacement equipment can switch between a hoisting state and a mobile state. When the nuclear-grade battery replacement equipment is in a hoisting state, the leg assembly 13 extends and supports the ground, lifts the base 11 and lifts the running wheels off the ground, the lifting mechanism 30 rises, and the boom mechanism 40 extends; when the nuclear-grade battery replacement equipment is in a mobile state, the leg assembly 13 is separated from the ground and retracted into the base 11, the running wheels can roll on the ground, the lifting mechanism 30 retracts to reduce the height of the boom mechanism 40, and the boom mechanism 40 also retracts to the limit position. When the boom mechanism 40 is retracted to the limit position, the projection of the boom mechanism 40 on the horizontal plane does not exceed the base 11.

[0053] Specifically, the nuclear-grade battery replacement equipment provided in this embodiment hoists the battery 100 through the lifting mechanism 50, the arm mechanism 40 and the slewing mechanism 20 respectively drive the lifting mechanism 50 to extend horizontally and rotate around the vertical axis, and the lifting mechanism 30 drives the arm mechanism 40 to rise and fall to adjust the lifting height. The nuclear-grade battery replacement equipment moves on the ground through the mobile base 10. When moving, on the one hand, the leg assembly 13 can be retracted into the base 11, and on the other hand, when the arm mechanism 40 is retracted to the extreme position, the projection of the arm mechanism 40 on the horizontal plane does not exceed the base 11, that is, the lateral size of the nuclear-grade battery replacement equipment when moving does not exceed the base 11, and the structure is compact, which is suitable for moving in a small space. In summary, the nuclear-grade battery replacement equipment provided in this embodiment can flexibly hoist the battery 100 without setting a hoisting point on the building, and the structure is compact, and it can be moved and used in a small space.

[0054] For example, Figure 1-Figure 4 As shown, the leg assembly 13 includes a first arm 131, a second arm 132 and a lifting leg 133. The first arm 131 is slidably disposed on the base 11 in the horizontal direction, the second arm 132 is slidably disposed through the first arm 131 in the horizontal direction, and the lifting leg 133 includes a lifting stud 1331, a leg plate 1332 and a leg hand wheel 1333. The lifting stud 1331 is disposed through the vertical direction and is threadedly connected to an end of the second arm 132 away from the first arm 131. The leg plate 1332 is mounted on the lower end of the lifting stud 1331, and the leg hand wheel 1333 is mounted on the upper end of the lifting stud 1331. The operator can manually pull the first arm 131 and the second arm 132 to extend and retract, and drive the lifting stud 1331 to rise and fall by rotating the leg hand wheel 1333, so that the leg plate 1332 touches the ground or leaves the ground.

[0055] Exemplarily, the leg plate 1332 and the leg hand wheel 1333 are both detachably connected to the lifting stud 1331 by means of pins or buckles. When the nuclear-grade battery replacement device is switched to a mobile state, the leg plate 1332 and the leg hand wheel 1333 can be removed to further reduce the lateral size and weight and improve the flexibility of movement. In some embodiments, the entire leg assembly 13 can also be detachably connected to the base 11 so that the entire leg assembly 13 can be removed in the mobile state to further reduce the lateral size and weight.

[0056] For example, Figure 1-Figure 4 As shown, the base 11 is configured as a rectangular disk structure, and the mobile base 10 includes four leg assemblies 13 , which are respectively installed at the four corners of the base 11 . When the leg assemblies 13 are retracted, the leg assemblies 13 are embedded in the base 11 .

[0057] For example, Figure 1 and Figure 3 As shown, the moving wheels 12 include two universal wheels and two fixed wheels, and the two universal wheels and the two fixed wheels are all installed at the bottom of the base 11.

[0058] For example, Figure 1-Figure 4 As shown, the slewing mechanism 20 includes a slewing reducer 21 and a slewing hand wheel 22. The slewing reducer 21 includes an inner ring, an outer ring and a worm gear reduction assembly. The inner ring is fixed to the base 11, and the outer ring is sleeved on the outer periphery of the inner ring. The outer ring is connected to the lower end of the lifting mechanism 30. The output shaft of the worm gear reduction assembly is connected to the outer ring in a driving manner. The slewing hand wheel 22 is connected to the input shaft of the worm gear reduction assembly. The operator can rotate the slewing hand wheel 22 to drive the outer ring and the lifting mechanism 30 to rotate slowly around the vertical axis to adjust the telescopic direction of the boom mechanism 40.

[0059] Exemplarily, the rotary handwheel 22 is detachably connected to the input shaft of the worm gear reduction assembly by means of pins or snaps. When the nuclear-grade battery replacement equipment is switched to a mobile state, the rotary handwheel 22 can be removed to further reduce the lateral size and weight and improve the flexibility of movement.

[0060] For example, Figure 3 and Figure 4 As shown, the base 11 is configured as a square disk structure. When the nuclear-grade battery replacement equipment is in a mobile state, the slewing mechanism 20 drives the boom mechanism 40 to rotate to the diagonal direction of the base 11, so that the boom mechanism 40 and both sides of the base 11 are at a 45° angle, so as to minimize the lateral size of the boom mechanism 40 in the mobile state.

[0061] For example, Figure 1 and Figure 3As shown, the lifting mechanism 30 includes a fixed column 31, a lifting column 32, a worm gear screw lift 33 and a lifting hand wheel 34. Among them, the lower end of the fixed column 31 is connected to the execution end of the rotary mechanism 20, the lifting column 32 is vertically penetrated in the fixed column 31, the upper end of the lifting column 32 is connected to the boom mechanism 40, the worm gear screw lift 33 is installed on the fixed column 31 and the execution end of the rotary mechanism 20, the upper end of the screw of the worm gear screw lift 33 is connected to the lifting column 32, and the lifting hand wheel 34 is connected to the input shaft of the worm gear screw lift 33. The operator can drive the screw and the lifting column 32 to slowly rise and fall by turning the lifting hand wheel 34 to adjust the height of the boom mechanism 40.

[0062] For example, Figure 1 and Figure 3 As shown, the fixed column 31 is provided with a locking hole, and the lifting column 32 is provided with a plurality of height adjustment holes arranged at intervals in the vertical direction. The lifting mechanism 30 also includes a height locking pin 35, which can be simultaneously penetrated in the locking hole and any height adjustment hole to carry the lifting column 32. When the worm screw lift 33 drives the lifting column 32 and the boom mechanism 40 to rise to a preset height, the locking hole is aligned with one of the corresponding height adjustment holes, and the height locking pin 35 is inserted at this time. The height locking pin 35 penetrates the locking hole and the corresponding height adjustment hole, and then the operator reversely rotates the lifting hand wheel 34 to lower the screw rod to a certain height. At this time, the lifting column 32 is completely supported by the height locking pin 35.

[0063] It should be noted that, on the one hand, the locking hole radially penetrates the fixed column 31, and the height adjustment hole also radially penetrates the lifting column 32. After the locking pin 35 is inserted, it simultaneously penetrates the fixed column 31 and the lifting column 32, thereby improving the reliability of the support. On the other hand, the upper end of the screw rod is floatingly connected to the lifting column 32 through a floating joint, so the screw rod has a certain amount of movement space when the lifting column 32 is supported by the locking pin 35.

[0064] For example, Figure 1 and Figure 2 As shown, the boom mechanism 40 includes a basic arm 41, a first telescopic arm 42, a second telescopic arm 43 and a third telescopic arm 44 which are sequentially connected and slidably connected in the same horizontal direction. The basic arm 41 is installed at the upper end of the lifting mechanism 30, and the lifting mechanism 50 is installed at the third telescopic arm 44. The boom mechanism 40 also includes a boom telescopic driving member 45, one end of which is connected to the basic arm 41, and the other end is connected to the first telescopic arm 42. When working, the operator first selectively pulls out the second telescopic arm 43 and the third telescopic arm 44 according to the hoisting radius corresponding to the position of the battery 100 to be replaced. When the hoisting operation is to be performed, the boom telescopic driving member 45 drives the first telescopic arm 42 to telescope.

[0065] Exemplarily, when the second telescopic arm 43 and the third telescopic arm 44 are fully extended, the effective lifting radius of the boom mechanism 40 is 1740-2240 mm; when the second telescopic arm 43 is extended and the third telescopic arm 44 is retracted, the effective lifting radius of the boom mechanism 40 is 1240-1740 mm.

[0066] Exemplarily, the boom telescopic drive member 45 may be an electric push rod or a hydraulic cylinder.

[0067] Exemplarily, the lifting mechanism 50 adopts an electric hoist, specifically a chain electric hoist, and a hook is provided at the execution end of the lifting mechanism 50, and the hook is used to connect the battery 100.

[0068] Exemplarily, the lifting mechanism 50 is detachably connected to the boom mechanism 40 by fastening bolts. When the nuclear-grade battery replacement device is switched to a mobile state, the lifting mechanism 50 is removed to reduce the lateral size and weight and improve the flexibility of movement.

[0069] For example, Figure 1-Figure 4 As shown, the nuclear-grade battery replacement equipment also includes a counterweight assembly, which includes a counterweight seat 61 and a plurality of counterweight blocks 62. The counterweight seat 61 is installed at the execution end of the slewing mechanism 20, and the plurality of counterweight blocks 62 are detachably installed on the counterweight seat 61. The counterweight seat 61 is located on the side of the lifting mechanism 30 that is away from the extension direction of the boom mechanism 40. The operator can install a corresponding number of counterweight blocks 62 according to the weight of the battery 100 and the lifting radius of the boom mechanism 40 to prevent the nuclear-grade battery replacement equipment from tipping over. When the nuclear-grade battery replacement equipment is switched to the mobile state, the counterweight blocks 62 are removed to reduce the lateral size and weight and improve the flexibility of movement.

[0070] Furthermore, a first locking hole is provided on the counterweight seat 61, and a second locking hole is provided on the counterweight seat 61. After the counterweight block 62 is placed on the counterweight seat 61, the first locking hole is aligned with the multiple second locking holes, and after the locking screw 63 is passed through the first locking hole and the multiple second locking holes, a nut is screwed on the locking screw 63 to fix the counterweight block 62.

[0071] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
