Description

Technical Field

[0001] This invention relates to the field of nuclear power plant equipment technology, specifically to a finger sleeve insertion and removal device. Background Technology

[0002] Finger sleeves are crucial components in the nuclear energy field, especially in nuclear power plants, used to support and position fuel assemblies or other critical equipment within the reactor core. Finger sleeves must withstand extreme environments such as high temperatures, high pressures, and radiation; therefore, their material selection, structural design, and manufacturing processes must meet extremely high standards.

[0003] Finger sleeve insertion and removal equipment is mainly divided into two categories: grippers that grab from the top of the reactor core and extractors that pull from the bottom of the reactor core. Both grippers and extractors involve complex mechanical structures and electronic equipment, resulting in high overall costs. While grippers are powerful, they are complex and require a large number of operators, demanding significant space and coordination from the operators. Extractors, on the other hand, can only replace one finger sleeve per refueling cycle and cannot handle broken finger sleeves, which may impose limitations in practical applications. Both types of insertion and removal equipment are relatively complex to operate and have low performance. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a finger sleeve insertion and removal device.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A finger sleeve insertion and removal device, comprising:

[0006] The base provides stable support for the entire device.

[0007] A control box is slidably mounted on the base and slides laterally along the base. The control box provides intelligent guidance for the operation of the equipment through control elements installed inside the control box.

[0008] Z-axis lifting mechanism, which is vertically mounted on the control box;

[0009] The Y-axis moving mechanism is slidably mounted on the Z-axis lifting mechanism and slides up and down along the Z-axis lifting mechanism;

[0010] The insertion and removal mechanism is horizontally slidably mounted on the Y-axis moving mechanism and slides horizontally along the Y-axis moving mechanism, while simultaneously sliding up and down together with the Y-axis moving mechanism along the Z-axis lifting mechanism.

[0011] Furthermore, the insertion and extraction mechanism includes a bracket, an upper roller assembly and a lower roller assembly respectively disposed on the bracket, and clamping assemblies respectively disposed at both ends of the bracket. An insertion and extraction gap is formed between the upper roller assembly and the lower roller assembly, and the insertion and extraction gap corresponds to the clamping cavity of the clamping assembly. The bracket is disposed on the Y-axis moving mechanism. After the finger sleeve is clamped by the clamping assembly, the insertion and extraction mechanism and the finger sleeve are moved as a whole by the Y-axis moving mechanism. After moving to the designated position, the finger sleeve is pulled out laterally by the roller assembly.

[0012] Furthermore, both the upper roller assembly and the lower roller assembly include a drive motor, a transmission assembly, and multiple sets of rollers. The transmission assembly is connected to the output end of the drive motor and transmits power to the rollers. The insertion / removal gap is formed between the rollers of the upper roller assembly and the rollers of the lower roller assembly.

[0013] Furthermore, the clamping assembly includes an upper clamping block and a lower clamping block respectively disposed on the bracket, and clamping grooves are respectively formed on the upper clamping block and the lower clamping block, forming the clamping cavity between the clamping groove of the upper clamping block and the clamping groove of the lower clamping block.

[0014] Furthermore, the outer side of the clamping assembly is provided with a position sensor for detecting the finger sleeve connector, and the position sensor is communicatively connected to the control element in the control box.

[0015] Furthermore, the bracket is also rotatably equipped with guide wheels for guiding the finger sleeve.

[0016] Furthermore, an arc-shaped support is provided between the clamping cavity and the insertion / removal gap to support the finger sleeve.

[0017] Furthermore, the Z-axis lifting mechanism includes a support plate, a first motor, a first screw rod, and a first screw seat. The support plate is vertically mounted on the control box, the first motor is mounted on the support plate, the first screw rod is connected to the output end of the first motor, the first screw seat is slidably mounted on the support plate and connected to the first screw rod, the first screw rod drives the first screw seat to move along the support plate, and the Y-axis moving mechanism is mounted on the first screw seat.

[0018] The support plate is provided with a first slide rail at each end, and the horizontal plate of the Y-axis moving mechanism is provided with a first slide block at each end that slides in cooperation with the first slide rail.

[0019] Furthermore, the Y-axis moving mechanism includes a horizontal plate, a second motor, a second helical rod, and a second helical seat. The horizontal plate is horizontally disposed on the first helical seat, the second motor is disposed on the horizontal plate, the second helical rod is connected to the output end of the second motor, the second helical seat is slidably disposed on the horizontal plate and connected to the second helical rod, the second helical rod drives the second helical seat to move along the horizontal plate, and the insertion and removal mechanism is disposed on the second helical seat.

[0020] The horizontal plate is provided with second slide rails on both sides, and the insertion and extraction mechanism is provided with a second slide block that slides in cooperation with the second slide rails.

[0021] Furthermore, the base is provided with third slide rails on both sides, one side of which is provided with continuous gear teeth that mesh with a drive gear located at the bottom of the control box. The drive gear is driven by a third motor located inside the control box. The other side of the third slide rail is connected to a third slide block located at the bottom of the control box.

[0022] Furthermore, multiple auxiliary positioning blocks are provided on both end faces of the base.

[0023] The present invention has the following beneficial effects: The finger cot insertion and removal device provided by the present invention has a reliable structure. The entire device moves laterally along the base via a control box, and is lifted vertically via a Z-axis lifting mechanism and horizontally via a Y-axis moving mechanism, thus forming movement in three directions (X, Y, and Z). This allows the insertion and removal mechanism to reach any designated position to perform finger cot insertion and removal operations as needed, making it convenient and quick, suitable for various operating locations. Furthermore, during the insertion and removal process, the clamping, guiding, and roller-driven mechanisms effectively prevent damage to the finger cot caused by excessive length, improving performance. In addition, the entire insertion and removal process is fully automated, greatly reducing manual labor intensity. Attached Figure Description

Detailed Implementation

[0031] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0032] like Figures 1 to 3 As shown, a finger cannula insertion and removal device includes a base 1, a control box 2, a Z-axis lifting mechanism 3, a Y-axis moving mechanism 4, and an insertion / removal mechanism 5. The base 1 provides stable support for the entire device. The control box 2 is slidably mounted on the base 1 and slides laterally along the base 1. Intelligent guidance for device operation is provided by control elements installed within the control box 2; these control elements can be microcontrollers. The Z-axis lifting mechanism 3 is vertically mounted on the control box 2, and the Y-axis moving mechanism 4 is slidably mounted on the Z-axis lifting mechanism 3, sliding up and down along it. The insertion / removal mechanism 5 is horizontally slidably mounted on the Y-axis moving mechanism 4 and slides horizontally along it, while simultaneously sliding up and down along the Z-axis lifting mechanism 3 together with the Y-axis moving mechanism 4.

[0033] like Figure 4The insertion / removal mechanism 5 includes a bracket 50, an upper roller assembly 51 and a lower roller assembly 52 respectively mounted on the bracket 50, and clamping assemblies 53 respectively mounted at both ends of the bracket 50. An insertion / removal gap 54 is formed between the upper roller assembly 51 and the lower roller assembly 52, which corresponds to the clamping cavity 533 of the clamping assembly 53. The bracket 50 is mounted on a Y-axis moving mechanism. After the finger sleeve is clamped by the clamping assembly 53, the insertion / removal mechanism 5 and the finger sleeve are moved as a whole by the Y-axis moving mechanism. After moving to the designated position, the finger sleeve is pulled out laterally by the roller assembly. During this process, the position sensor 55 mounted on the outer side of the clamping assembly 53 detects the position of the finger sleeve connector. When the finger sleeve connector is detected, the position sensor 55 transmits the detection signal to the controller. The controller controls the upper roller assembly 51 and the lower roller assembly 52 to work, and then drives the finger sleeve to perform the insertion / removal operation.

[0034] Both the upper roller assembly 51 and the lower roller assembly 52 include a drive motor 510, a transmission assembly, and multiple sets of rollers 511. The transmission assembly is connected to the output end of the drive motor 510 and transmits power to the rollers 511. An insertion / removal gap 54 is formed between the rollers 511 of the upper roller assembly 51 and the rollers 511 of the lower roller assembly 52. ​​The transmission assembly can adopt a belt and pulley structure, with the pulley and rollers 511 coaxially arranged. When the drive motor 510 starts, it transmits power to the rollers 511 through the belt and pulley. The rollers 511 rotate, and under the action of friction, they drive the finger sleeve to move, realizing the insertion and removal operation of the finger sleeve.

[0035] Furthermore, the clamping assembly 53 includes an upper clamping block 530 and a lower clamping block 531 respectively disposed on the bracket 50. Clamping grooves 532 are respectively formed on the upper clamping block 530 and the lower clamping block 531, forming a clamping cavity 533 between the clamping grooves 532 of the upper clamping block 530 and the lower clamping block 531. To improve the smoothness of the insertion and removal operation, a guide wheel 56 for guiding the finger sleeve is also rotatably disposed on the bracket 50. Additionally, due to the relatively long length of the finger sleeve, to prevent bending during insertion and removal, an arc-shaped support 57 is provided between the clamping cavity 533 and the insertion / removal gap 54 to support the finger sleeve. The arc-shaped support 57 provides support to the finger sleeve, preventing uneven stress and bending deformation.

[0036] like Figure 5As shown, the Z-axis lifting mechanism 3 includes a support plate 30, a first motor 31, a first screw rod 32, and a first screw seat 33. The support plate 30 is vertically mounted on the control box 2. The first motor 31 is mounted on the support plate 30. The first screw rod 32 is connected to the output end of the first motor 31. The first screw seat 33 is slidably mounted on the support plate 30 and connected to the first screw rod 32. The first screw rod 32 drives the first screw seat 33 to move along the support plate 30. The Y-axis moving mechanism 4 is mounted on the first screw seat 33. The drive motor 510 is communicatively connected to the controller. The first screw rod 32 is connected to the output shaft of the drive motor 510 via a coupling or bushing. The other end of the first screw rod 32 is connected to the support plate 30 via a bearing. The outer surface of the first screw rod 32 is provided with external helical teeth. The interior of the first screw seat 33 has a through hole, and an internal helical tooth matching the external helical tooth is provided in the through hole. During operation, the drive motor 510 starts, causing the first spiral rod 32 to rotate, which in turn drives the first spiral seat 33, which is fitted on the first spiral rod 32, to move, thereby driving the Y-axis moving mechanism 4, which is set on the first spiral seat 33, to move up and down.

[0037] To improve the stability of the Y-axis moving mechanism 4 sliding along the Z-axis lifting mechanism 3, the present invention provides first slide rails 34 at both ends of the support plate 30, and first slide blocks 35 that slide in cooperation with the first slide rails 34 are provided at both ends of the horizontal plate 40 of the Y-axis moving mechanism 4. This side-supported sliding effectively improves the stability of the sliding process and prevents tilting or shaking during sliding.

[0038] The Y-axis moving mechanism 4 includes a horizontal plate 40, a second motor 41, a second helical rod 42, and a second helical seat 43. The horizontal plate 40 is horizontally mounted on the first helical seat 33. The second motor 41 is mounted on the horizontal plate 40. The second helical rod 42 is connected to the output end of the second motor 41. The second helical seat 43 is slidably mounted on the horizontal plate 40 and connected to the second helical rod 42. The second helical rod 42 drives the second helical seat 43 to move along the horizontal plate 40. The insertion / removal mechanism 5 is mounted on the second helical seat 43. The Z-axis lifting mechanism 3 works on the same principle. The second motor 41 drives the second helical rod 42 to rotate, which in turn drives the second helical seat 43 to move, thereby driving the insertion / removal mechanism 5 to move horizontally. In addition, to improve the stability of the movement, second slide rails 44 are provided on both sides of the horizontal plate 40, and the insertion / removal mechanism 5 is provided with a second slide seat 45 that slides with the second slide rails 44.

[0039] To improve the smoothness of the overall movement of the equipment along the X-axis, such as Figure 6As shown, in this invention, the base 1 has third slide rails 10 on both sides. One side of the third slide rail 10 has continuous gear teeth 11, which mesh with a drive gear 12 located at the bottom of the control box 2. The drive gear 12 is driven by a third motor 14 located inside the control box 2. The other side of the third slide rail 10 has a third slide block 13 connected to it, and the third slide block 13 is located at the bottom of the control box 2. The third motor 14 drives the drive gear 12 to rotate, and the gear meshes with the gear teeth 11 on the slide rail, driving the control box 2 to move along the slide rail in the opposite direction. Thus, the overall movement of the control box 2 and the components on the control box 2 is achieved by the forward and reverse rotation of the third motor 14.

[0040] In order to improve the stability of the equipment, in this invention, multiple auxiliary positioning blocks are provided on both ends of the base 1, which play a positioning role for the base 1.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
