Description

Technical Field

[0001] This invention relates to the field of nuclear material storage and transfer technology, specifically to a suspended basket gripper. Background Technology

[0002] During nuclear power plant operation, spent fuel assemblies unloaded from the reactor need to be temporarily stored in spent fuel pools for cooling before subsequent transfer or reprocessing. Traditional spent fuel storage methods primarily use fixed storage racks, operating on a per-assembly basis. However, this method has limited daily processing capacity, making it difficult to meet the efficiency requirements of reprocessing plants. Furthermore, single-assembly operations require multiple transfers, which is not only time-consuming but also increases the risk of assembly falling. In addition, traditional rack storage requires deep pools, resulting in high construction costs and a heavy burden on pool water cooling and purification. To improve the efficiency of spent fuel unloading and transfer in wet storage facilities, basket-style solutions have been increasingly adopted in recent years. Baskets can accommodate multiple sets of spent fuel assemblies at once and reduce the number of transfers through integrated operations. This solution can also reduce the pool depth to approximately 9 meters, reducing water injection volume and operating costs.

[0003] The special structure of the gondola places higher demands on the grabbing tools. To address this, existing technologies, such as CN119018763A, propose an underwater grabbing device for a visualized spent fuel storage gondola, comprising: a grabbing unit including a hook assembly and a movable cylinder, the hook assembly being located on the outer side of the movable cylinder for grabbing the gondola; a drive unit including a cylinder and a cylinder piston shaft, the piston shaft having a cylinder at its top and its bottom extending into the movable cylinder, the cylinder controlling the piston shaft's up-and-down movement within the movable cylinder; and a visualization unit including a camera installed at the lower end of the movable cylinder for observing the connection between the hook assembly and the gondola. Another example is CN220412825U, which proposes a multi-purpose grabbing tool suitable for gondola installation, including a grabbing body and limiting components for positioning the gondola's bottom plate, both detachably connected to the grabbing body; the grabbing body has a first mounting hole for mounting the gondola's bottom plate. This technical solution allows the base plate of the suspended platform to be installed onto the gripper body, making the gripper body serve as the installation base for the suspended platform and thus enabling the installation of the suspended platform.

[0004] However, existing technologies still face technical challenges such as complex structures and high manufacturing costs. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention provides a suspended basket gripper, comprising a positioning bracket, a driving component, and two or more locking components, and further comprising a first transmission mechanism and two or more second transmission mechanisms. The first transmission mechanism is connected to the driving component, and the driving component is capable of driving the first transmission mechanism to move vertically. The first transmission mechanism and the second transmission mechanism are in sliding contact. The locking component comprises a locking seat and a locking member. The locking seat is fixed below the positioning bracket, and the locking member is movably connected to the second transmission mechanism. The driving component is capable of driving the locking member to move horizontally through the first transmission mechanism and the second transmission mechanism to achieve locking of the suspended basket by the locking member.

[0007] Furthermore, the driving component is fixed to the positioning bracket, and two or more locking components are arranged at intervals along the circumference of the driving component, with the driving component located above the locking components.

[0008] Furthermore, the first transmission mechanism includes a first transmission member connected to the driving component; the second transmission mechanism includes an ear seat, a second transmission member, and a first connecting member; the ear seat is fixed below the positioning bracket; the first connecting member is hinged to the locking member; and the second transmission member is hinged to the ear seat and the first connecting member respectively; two or more second transmission members are arranged radially outside the first transmission member at intervals along the circumference of the driving component, and the first transmission member and the second transmission member are in sliding contact.

[0009] Furthermore, the second conductive member includes a first guide portion, a second guide portion, and a first connecting portion. The first connecting portion is hinged to the ear seat, the first connecting portion is fixed to the second guide portion, the first guide portion is fixed to the second guide portion, and the first guide portion is located above the second guide portion.

[0010] Furthermore, the angle between the extending direction of the first guide portion and the extending direction of the second guide portion is between 80° and 150°, and the first guide portion is inclined from bottom to top toward the direction close to the first conductive member.

[0011] Furthermore, the first conductive member includes a plurality of sides extending in a vertical direction, and the first conductive mechanism further includes a roller, the roller being fixed to the side of the first conductive member extending in a vertical direction, and the roller being able to roll along the first guide portion and the second guide portion.

[0012] Furthermore, the first transmission mechanism also includes a guide rod, which is movably fixed to the positioning bracket. The guide rod extends vertically and is movable relative to the positioning bracket in the vertical direction. The lower end of the guide rod is fixed to the first transmission element.

[0013] Furthermore, the guide rod includes a second connecting portion, which is disposed at the uppermost end of the guide rod. The second connecting portion can be connected to an external loading device to allow the guide rod to move in a vertical direction.

[0014] Furthermore, the first transmission mechanism also includes an elastic element, the guide rod passes through the elastic element, and the elastic element is located between the first transmission element and the positioning bracket.

[0015] Furthermore, the locking seat includes a first groove, which is formed on the surface of the locking seat. The opening of the first groove faces downward, and the locking member can move horizontally through the sidewall of the first groove to put the locking member into a locked state.

[0016] Furthermore, the locking member also includes a second groove, which is formed on the surface of the locking member; when the locking member is in the locked state, the opening of the second groove is opposite to the opening of the first groove, and the second groove and the first groove extend in the same direction.

[0017] Furthermore, it also includes two or more guide frames, which are fixed to the lower part of the positioning bracket along the circumference of the driving component. Each guide frame includes a guide slope that is inclined from top to bottom away from the driving component. The outer shell of the basket can slide along the guide slope towards the first groove.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] The present invention will be further described in detail below with reference to specific embodiments, which should not be construed as limiting the scope of protection claimed by the present invention.

[0028] Example

[0029] According to one aspect of the present invention, a basket grabber is provided, such as Figure 1-5 As shown, the system includes a positioning bracket 1, a driving component 2, and two or more locking components 3. It also includes a first transmission mechanism 4 and two or more second transmission mechanisms 5. The first transmission mechanism 4 is connected to the driving component 2, and the driving component 2 can drive the first transmission mechanism 4 to move vertically. The first transmission mechanism 4 and the second transmission mechanism 5 are in sliding contact. The locking component 3 includes a locking seat 31 and a locking member 32. The locking seat 31 is fixed below the positioning bracket 1, and the locking member 32 is movably connected to the second transmission mechanism 5. The driving component 2 can drive the locking member 32 to move horizontally through the first transmission mechanism 4 and the second transmission mechanism 5 to lock the basket.

[0030] Specifically, the suspended platform gripper is mounted on the external loading device for the operation of transferring the suspended platform. The interface between the suspended platform gripper and the external loading device is rigidly connected. The first transmission mechanism 4 and the second transmission mechanism 5 are components that transmit the thrust of the drive component 2 and perform insertion and removal operations and guide the locking component 32 during the lifting process. Neither of them are load-bearing structures, but their structural strength and tensile performance must meet the requirements of long-term use without deformation.

[0031] like Figure 1-2 As shown, the driving component 2 is fixed to the positioning bracket 1, and two or more locking components 3 are spaced apart circumferentially along the driving component 2, with the driving component 2 located above the locking components 3. Specifically, in this embodiment, the vertical projection of the positioning bracket 1 is a quadrilateral, the driving component 2 is fixed at the centroid of the positioning bracket 1, and the locking components 3 are arranged along the sides of the positioning bracket 1. In this embodiment, the locking components 3 are arranged along two opposite sides of the positioning bracket 1.

[0032] Specifically, the driving component 2 is a cylinder. Optionally, all internal seals of the cylinder are made of radiation-resistant material. The cylinder diameter is Φ100mm, the stroke is 120mm, the operating pressure is 0.15~1.0Mpa, and the push / pull force is 785 / 705 kg. This cylinder is equipped with a dedicated three-position five-way valve, ensuring it maintains its original working state even in the event of accidental power failure or pressure relief. This prevents the suspended platform from separating from the gripper and falling due to accidental power failure or pressure relief, improving safety and reliability. An explosion-proof pressure-bearing air pipe is used between the cylinder and the solenoid valve. The outer layer of the air pipe is protected by stainless steel wire, effectively preventing damage from accidental scratches or friction.

[0033] The first transmission mechanism 4 includes a first transmission member 41, which is connected to the driving component 2. The second transmission mechanism 5 includes an ear seat 51, a second transmission member 52, and a first connecting member 53. The ear seat 51 is fixed below the positioning bracket 1. The first connecting member 53 is hinged to the locking member 32. The second transmission member 52 is hinged to both the ear seat 51 and the first connecting member 53. Two or more second transmission members 52 are arranged radially outside the first transmission member 41 at intervals along the circumference of the driving component 2. The first transmission member 41 and the second transmission member 52 are in sliding contact. The second transmission member 52 includes a first guide portion 521, a second guide portion 522, and a first connecting portion 523. The first connecting portion 523 is hinged to the ear seat 51 and fixed to the second guide portion 522. The first guide portion 521 is fixed to the second guide portion 522, and the first guide portion 521 is located above the second guide portion 522.

[0034] Specifically, such as Figure 1-2 As shown, the ear seat 51 is fixed to the lower part of the positioning bracket 1 by welding. The first guide portion 521 and the second guide portion 522 are connected by a smooth arc surface. The angle between the extending direction of the first guide portion 521 and the extending direction of the second guide portion 522 is 115°, and the first guide portion 521 is inclined from bottom to top towards the first conductive member 41. Optionally, in other embodiments, the angle between the extending direction of the first guide portion 521 and the extending direction of the second guide portion 522 can also be 80°, 100°, 120°, 140°, and 150°, etc.

[0035] The first conductive member 41 includes a plurality of sides extending in a vertical direction, and the first conductive mechanism 4 also includes a roller, which is fixed to the side of the first conductive member 41 extending in a vertical direction and is capable of rolling along the first guide portion 521 and the second guide portion 522.

[0036] Specifically, in this embodiment, the first conductive member 41 is a rectangular plate structure, and rollers are disposed at the four corners of the first conductive member 41. When the first conductive member 41 rises, the rollers push the first guide portion 521 and the second guide portion 522 to rotate around the connection point on the first connecting portion 523, thereby causing the first connecting portion 523 to drive the locking member 32 to retract, thus unlocking the locking member 3. When the first conductive member 41 descends, the rollers push the first guide portion 521 and the second guide portion 522 to rotate around the connection point on the first connecting portion 523, thereby causing the first connecting portion 523 to drive the locking member 32 to extend, thus locking the locking member 3.

[0037] like Figure 1-3As shown, the first transmission mechanism 4 further includes a guide rod 42, which is movably fixed to the positioning bracket 1. The guide rod 42 extends vertically and is movable relative to the positioning bracket 1 in the vertical direction. The lower end of the guide rod 42 is fixed to the first transmission member 41. The first transmission mechanism 4 also includes an elastic member 43, through which the guide rod 42 passes. The elastic member 43 is located between the first transmission member 41 and the positioning bracket 1.

[0038] Specifically, the guide rod 42 is movably fixed to the positioning bracket 1 by a nut. The relative position of the guide rod 42 and the positioning bracket 1 is adjusted by the nut, thereby adjusting the extension position of the locking member 32 in the locked state. Throughout the entire process of the first transmission member 41 moving up and down, the elastic member 43 is always in a compressed state.

[0039] Optionally, the first transmission mechanism 4 is provided with two guide rods 42, the elastic element 43 is a spring, and the fixed position on the positioning bracket 1 of the driving component is located between the fixed positions of the two guide rods 42 on the positioning bracket 1.

[0040] The guide rod 42 includes a second connecting portion 421, which is located at the uppermost end of the guide rod 42. This second connecting portion can be connected to an external loading device to allow the guide rod 42 to move vertically. Specifically, the suspended platform gripper also includes a flexible connector. The second connecting portion has a through hole, and the first transmission mechanism 4 is connected to the external loading device through the flexible connector. In case of a fault, it is used to pull the guide rod 42 upwards, thereby causing the locking member 32 to move horizontally and unlock.

[0041] The locking seat 31 includes a first groove 311, which is formed on the surface of the locking seat 31. The opening of the first groove 311 faces downward. The locking member 32 can move horizontally through the side wall of the first groove 311 to lock the locking member 32. Optionally, the locking seat 31 is fixed to the positioning bracket 1 by bolts.

[0042] It should be noted here that the locking state refers to the state of the locking component when the locking component 32 moves horizontally through the side wall of the first groove 311 and the basket shell in the first groove 311, so that the basket shell is connected to the locking component.

[0043] The locking member 32 further includes a second groove 321, which is formed on the surface of the locking member 32. When the locking member 32 is in the locked state, the opening of the second groove 321 is opposite to the opening of the first groove 311, and the second groove 321 and the first groove 311 extend in the same direction. Specifically, when the locking member is in the locked state, the shell of the basket will be locked in the second groove 321 under the action of gravity to prevent accidental operation that would cause the locking member 32 to retract and unlock.

[0044] Optionally, in this embodiment, the main body of the locking component 32 is hard chrome plated and then ground by a high-precision grinding machine to ensure that the guide post part of the component has a sufficiently high surface hardness and a sufficiently low coefficient of friction, thereby ensuring smooth and non-jamming operation. Furthermore, when the locking component 32 is retracted to unlock, its frictional force must be overcome. This frictional force is greater than the force generated by accidental operation, thus preventing accidental unlocking and improving safety performance.

[0045] like Figure 3 As shown, the locking component 32 consists of a rectangular pin and a circular guide post. One end of the circular guide post has a notch and a pin hole, and it is connected to the first connecting component 53 via a pin shaft. The rectangular pin is clearance-fitted with the locking seat 31 to ensure that the locking seat 31 provides sufficient constraint and strength to the rectangular pin while ensuring smooth operation. Simultaneously, the dimensions of the rectangular pin and the dimensions of the suspended platform interface are also clearance-fitted, with a 3mm clearance on one side. Guide grooves are also provided on both sides of the rectangular pin, mainly to prevent the locking component 32 from tilting backwards in the later stages of its movement due to its own weight, ensuring smooth and effective connection.

[0046] Each locking component 32 is equipped with a first limit switch. When the locking component 3 enters the locking state, the first limit switch provides a locking completion signal. If any component fails to provide a signal, the system will issue an alarm signal and prohibit further action. Similarly, when the locking component 3 is locked, the first limit switch will also provide a corresponding signal. Furthermore, the driving component 2 is equipped with a second limit switch. When the locking component 3 enters the locking state, the second limit switch locks the driving component 2, preventing it from moving. When the locking component 3 unlocks, the second limit switch unlocks the driving component 2, allowing it to drive the locking component 32 to move. The first and second limit switches cooperate to achieve a double-layer protection function.

[0047] The suspended basket gripper also includes two or more guide frames 6, which are fixed circumferentially to the lower part of the positioning bracket 1 along the drive component 2. Each guide frame 6 includes a guide slope 61, which slopes from top to bottom away from the drive component 2. The outer shell of the suspended basket can slide along the guide slope 61 towards the first groove 311. Specifically, as... Figure 4-5 As shown, the guide frame 6 is positioned between the two locking components 3 or on the side of the positioning bracket 1 where no locking component 3 is provided. The guide ramp 61 provided in the guide frame 6 can guide, position, and center the suspended basket 9, ensuring that the centering operation is less difficult during operation, and the centering operation can be stably completed within a circumferential range of ±15mm.

[0048] The suspended platform gripper also includes two or more fixing members 7, one end of which is fixed to the top of the positioning bracket 1, and the other end of which is connected to an external loading device. Specifically, as shown in the figure... Figure 6 As shown, the design aims to enhance the connection stability between the grab and the automatic operating device. The design of the fixing component 7 not only ensures the stability of the suspended platform grab during the hoisting process, reducing the operational risks that may be caused by swaying or tilting, but also facilitates the quick disassembly and connection of the suspended platform grab, improving work efficiency.

[0049] The suspended platform gripper also includes a lifting component 8, which is fixed to the positioning bracket 1. The lifting component 8 has multiple through holes for connecting to an external loading device. During the gripping process, the lifting component 8 must bear the weight of both the suspended platform and the gripper itself; it must reliably connect to the external loading device without swaying or tilting, and it must be easy to disassemble and reassemble. Therefore, to ensure sufficient structural strength and safety, the component is designed as a whole, using high-quality stainless steel forgings. Its overall mechanical properties are improved through rigorous heat treatment, and it is then machined as a whole, effectively guaranteeing its structural strength and safety.

[0050] In some embodiments, the external loading device is a crane, and the crane is equipped with a trolley. The process of using the basket grab is as follows: the basket is grabbed and fixed under the trolley and its air and electrical circuits are connected; the trolley and the basket grab move to directly above the basket; the locking mechanism is opened to unlock the locking component; the trolley moves the basket grab downward to contact the underwater basket; the drive component drives the locking component to lock the basket grab to the basket; the trolley rises and moves the basket horizontally to the designated position; the locking mechanism is opened to separate the basket grab from the basket; the lifting action is completed.

[0051] By applying the above-described technical solution of the present invention, at least the following technical effects are achieved: 1. The suspended platform gripper proposed in this invention, through the unique design of the first transmission mechanism and the second transmission mechanism, achieves precise control of multiple locking components by a single drive component, which not only simplifies the equipment structure but also improves operational efficiency.

[0052] 2. The suspended basket gripper proposed in this invention has a second groove formed on the surface of the locking member. When the locking member is in the locked state, the second groove is locked with the outer shell of the suspended basket, ensuring that any misoperation will not cause the locking member to be released and retracted, thus ensuring the safety of operation.

[0053] 3. The suspended platform grab proposed in this invention has a second connecting part located at the uppermost end of the guide rod. In the event of an abnormal power or gas outage, the guide rod can be lifted upwards simply by using the second connecting part, which will ensure that the locking part retracts and unlocks the device.

[0054] 4. The suspended platform grab and guide frame proposed in this invention make the docking of the suspended platform and the grab more convenient, reduce the difficulty of centering, and improve the stability and reliability of operation.
