A material blocking device for an automated production line for conveying radioactive materials

Abstract

This invention provides a material-stopping device for an automated production line for radioactive material transport, belonging to the field of radioactive material transport. The device includes material-stopping sensors located on opposite sides of the automated production line and a base plate. The base plate has a mounting seat, the bottom of which is fixedly connected to a slide block. The slide block is fitted with a first slide rail. One end of the mounting seat has a carrier pusher block, and its side has a first rack that meshes with a gear. The gear rotates under the action of a servo motor, driving the mounting seat to move, causing the carrier pusher block to push and press the carrier to stop the material. A limit sensor is installed on the base plate to limit the first rack. This device can stop the material. After the sorting and detection camera sorts and detects the samples in the carrier and determines the material's destination, the servo motor rotates in the opposite direction, causing the carrier pusher block to retract. This avoids the entire line stopping and affecting the transport of other materials, improves transport efficiency, and prevents radiation damage to personnel from radioactive materials.

Description

Technical Field

[0001] This invention relates to the field of radioactive material conveying technology, and in particular to a material blocking device for an automated production line for radioactive material conveying. Background Technology

[0002] In the field of nuclear chemical engineering, the production and analysis of radioactive materials require material transfer from the receiving / dispatching point to the receiving point. During this transfer, the materials need to be classified and tested to determine their target orientation. Current operating models include two methods: complete line shutdown for classification and testing, and manual classification and testing. Complete line shutdown for testing reduces the transfer efficiency of automated production lines, while manual testing involves significant physical exertion for personnel. Furthermore, prolonged exposure to radioactive materials by classification and testing personnel can lead to radiation exposure, seriously harming their health.

[0003] For the reasons mentioned above, it is necessary to design a material blocking device for an automated production line for radioactive material transportation, so as to change the existing method of shutting down the entire line or manually inspecting, improve the transfer efficiency, reduce the labor intensity of personnel, realize the fully automated operation, and reduce the radiation dose received by operators. Summary of the Invention

[0004] The purpose of this invention is to provide a material blocking device for an automated production line for conveying radioactive materials. This device can stop radioactive materials on the automated production line, which facilitates the classification and detection of materials, determines the target direction, improves the sampling efficiency, reduces the labor intensity of operators, and reduces the radiation risk to operators.

[0005] This invention provides a material blocking device for an automated production line for conveying radioactive materials, comprising: a material blocking sensor and a base plate. The base plate is fixedly installed on one side of the automated production line, and the material blocking sensor is disposed on the opposite side of the base plate. A mounting seat is provided on the base plate, and the bottom of the mounting seat is fixedly connected to a slide block. The slide block is adapted to be installed on a first slide rail. A carrier push block is provided at the end of the mounting seat near the material blocking sensor. A first rack is provided on the side of the mounting seat, and the first rack is adapted to be meshed with a gear for transmission. The gear can rotate under the action of a servo motor, thereby driving the mounting seat and the slide block to move together along the first slide rail, and the carrier push block pushes and presses the carrier to achieve material blocking.

[0006] Preferably, a limit sensor is installed on the base plate, and the limit sensor is used to limit the extreme position of the first rack.

[0007] Preferably, the first slide rail is a linear slide rail, and its axis is perpendicular to the extension direction of the automated production line.

[0008] Preferably, the servo motor is mounted on the bottom of the base plate, and the output shaft of the servo motor passes through the base plate and is adapted to the gear provided on its surface to drive its rotation.

[0009] Preferably, a limit mechanism is also provided on the base plate. When the first rack moves to the limit position, the limit sensor senses the limit mechanism, and the servo motor stops rotating.

[0010] Preferably, the limiting mechanism includes a second slide rail and a limiting block located on the side of the gear away from the first rack. The limiting block is adapted to and installed on the second slide rail and can slide along it. A second rack adapted to mesh and drive the gear is provided on one side of the limiting block. When the gear rotates, the second rack and the first rack move in opposite directions.

[0011] Preferably, the gear is a spur gear, and the first rack and the second rack are spur racks that mesh with the gear.

[0012] Preferably, the second slide rail is a linear slide rail, and the axis of the second slide rail is parallel to the axis of the first slide rail.

[0013] Preferably, the limit sensor is located at the end of the second slide rail away from the stop sensor.

[0014] Preferably, both the limit sensor and the stop sensor are photoelectric position sensors.

[0015] The technical solution of this invention involves setting up a baffle sensor and a base plate on both sides of an automated radioactive material conveying line. A first slide rail and a slide block are provided on the base plate. The slide block can move along the first slide rail, and a mounting base is fixedly installed on the slide block. A carrier pusher is provided at the end of the mounting base near the baffle sensor. A first rack is provided on the side of the mounting base. A gear and a servo motor are provided on the base plate. When the baffle sensor detects a carrier containing radioactive material, the servo motor drives the gear to rotate, thereby causing the rack, mounting base, and slide block to move relative to the first slide rail. This moves the carrier pusher to the other side of the automated conveying line, clamping the carrier. After the classification and detection camera classifies and detects the samples inside the carrier to determine the destination of the material transfer, the servo motor rotates in the opposite direction, causing the carrier pusher to retract. This avoids affecting other material conveying due to line shutdown, improves transfer efficiency, changes the operating procedures of the detection personnel, and essentially avoids radiation damage to personnel during the transfer of radioactive materials.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features.

Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they may refer to a fixed connection, a detachable connection, or an integral connection; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; and they may refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] like Figure 1 As shown, this invention proposes a material blocking device for an automated production line for conveying radioactive materials, comprising: a material blocking sensor 1 and a base plate 2. The base plate 2 is fixedly installed on one side of the surface of the automated production line, and the material blocking sensor 1 is disposed on the opposite side of the base plate 2. A mounting seat 3 is disposed on the base plate 2, and the bottom of the mounting seat 3 is fixedly connected to a slide 4. The slide 4 is adapted to be installed with a first slide rail 5, which is disposed on the surface of the mounting seat 3. The first slide rail 5 is a linear slide rail, and its axis is perpendicular to the extension direction of the automated production line. A carrier push block 6 is disposed at the end of the mounting seat 3 near the material blocking sensor 1. A first rack 7 is disposed on the side of the mounting seat 3. The first rack 7 is adapted to be meshed with a gear 8 for transmission. The gear 8 can rotate under the action of a servo motor 9, thereby driving the mounting seat 3 and the slide 4 to move together along the first slide rail 5, and the material blocking is achieved by pushing and pressing the carrier through the carrier push block 6.

[0024] In this embodiment, the servo motor 9 is fixedly installed on the bottom of the base plate 2. The output shaft of the servo motor 9 passes vertically through the base plate 2 and is fitted with the mounting hole of the gear 8 on its surface. When the material blocking sensor 1 detects a carrier containing radioactive material, the output shaft of the servo motor 9 rotates, thereby driving the gear 8 to rotate, causing the first rack 7 and the mounting base 3 to move closer to the material blocking sensor 1. The carrier pusher 6 pushes the carrier to move laterally and then presses it to block the material, thus achieving material blocking.

[0025] Specifically, a limit sensor 10 is also installed on the base plate 2. The limit sensor 10 is used to limit the extreme position of the first rack 7 to prevent the first rack 7 from moving too far and separating from the gear 8. It can also prevent the servo motor 9 from running unnecessarily and avoid wasting power.

[0026] The base plate 2 is also provided with a limit mechanism to limit the extreme movement position of the first rack 7. When the first rack 7 moves to the extreme position, the limit sensor 10 senses the limit mechanism, and the system controls the servo motor 9 to stop rotating to prevent the first rack 7 from disengaging from the gear 8.

[0027] Specifically, the limit sensor 10 is located at the end of the second slide rail 11 away from the stop sensor 1. The limiting mechanism includes the second slide rail 11 and the limiting block 12 located on the side of the gear 8 away from the first rack 7. The second slide rail 11 is fixedly installed on the surface of the base plate 2. It is a linear slide rail with its axis parallel to the axis of the first slide rail 11. The limiting block 12 is adapted to be installed on the second slide rail 11 and can slide along it. A second rack 13 is provided on one side of the limiting block 12 and is adapted to mesh with the gear 8. When the gear 8 rotates, the second rack 13 and the first rack 7 move in opposite directions. When the first rack 7 moves towards the stop sensor 1, the limiting block 12 moves towards the limiting sensor 10 under the action of the gear 8 and the second rack 13.

[0028] In this embodiment, gear 8 is a spur gear, and the first rack 7 and the second rack 13 are spur racks that mesh with gear 8. Limit sensor 10 and stop sensor 1 are both photoelectric position sensors. When the carrier or limit block 12 passes through it, the photoelectric position sensor detects the obstruction, sends an electrical signal, and causes the system to perform a corresponding action.

[0029] The working principle of the material blocking device of the present invention is as follows:

[0030] When the material blocking sensor 1 detects a carrier containing radioactive material, the servo motor 9 drives the gear 8 to rotate counterclockwise. The gear 8 meshes with the first rack 7 and the second rack 13 simultaneously, causing the mounting base 3 and the slide 4 to move relative to the first slide rail 5. This moves the carrier pusher 6, pushing the carrier to the other side of the automated production line and clamping it. At this time, the second rack 13 drives the limit block 12 to move towards the limit sensor 10. When it reaches the position of the limit sensor 10, the limit sensor 10 sends an electrical signal, and the system controls the servo motor 9 to stop. After the classification and detection camera classifies and detects the samples in the carrier and determines the destination of the material transfer, the servo motor 9 rotates in the opposite direction, causing the carrier pusher 6 to retract. This avoids affecting the transportation of other materials due to the shutdown of the entire line, improves the transfer efficiency, changes the operating procedures of the testing personnel, and basically avoids radiation damage to personnel during the transfer of radioactive materials.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
