Description

Technical Field

[0001] This utility model relates to the field of disassembly and assembly technology of radioactive sources for neutron logging instruments, and particularly to a disassembly and assembly device for radioactive sources for neutron logging instruments. Background Technology

[0002] Neutron logging instruments typically store radioactive sources in a radioactive source container. The radioactive source, placed within the container, is usually secured by threaded connections. The radioactive source has locating slots or holes for disassembly and reassembly. To remove the radioactive source from the container, a specialized disassembly tool is needed to engage the locating slots or holes, unscrew the source, and then remove it from the container. However, because the radioactive source is prone to detaching from the disassembly tool and falling off after contact with the threaded connection, this process is inconvenient for disassembly and reassembly. Utility Model Content

[0009] According to any of the foregoing embodiments of this application, the disassembly and assembly shaft assembly includes a shaft, a coupling, and disassembly and assembly screws. The disassembly and assembly screws are connected to the shaft via the coupling and are used to disassemble and assemble the radioactive source of the neutron logging instrument.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This application provides a device for disassembling and assembling a radioactive source for a neutron logging instrument, which can prevent the radioactive source from falling during disassembly and assembly, and facilitate the disassembly and assembly of the radioactive source.

[0021] Figure 1 This is a cross-sectional structural schematic diagram of the disassembly and assembly device for the radioactive source of a neutron logging instrument in one embodiment of this application. Figure 1 As shown in the figure, this application embodiment provides a disassembly and assembly device 1000 for a neutron logging instrument radioactive source. The disassembly and assembly device 1000 includes a frame body 100, a disassembly and assembly drive component 200, a limiting sleeve 300, and a telescopic component 400. The disassembly and assembly drive component 200 is installed on the frame body 100. The disassembly and assembly drive component 200 includes a disassembly and assembly rotating shaft assembly 210 for disassembling and assembling the radioactive source. The limiting sleeve 300 is installed on the frame body 100. The working end of the disassembly and assembly rotating shaft assembly 210 is coaxially disposed within the limiting sleeve 300. The telescopic component 400 is connected to the disassembly and assembly drive component 200, and the telescopic component 400 can drive the disassembly and assembly rotating shaft assembly 210 to extend and retract relative to the limiting sleeve 300 along its own axial direction.

[0022] It should be noted that the working end of the disassembly and assembly shaft assembly 210 specifically refers to the execution end of the disassembly and assembly shaft assembly 210. The working end of the disassembly and assembly shaft assembly 210 can cooperate with the radiation source. The disassembly and assembly drive component 200 can drive the disassembly and assembly shaft assembly 210 to rotate along its own axis in order to disassemble and assemble the radiation source.

[0023] The telescopic component 400 can drive the disassembly and assembly shaft assembly 210 to extend and retract axially relative to the limiting sleeve 300. This can be understood as the working end of the disassembly and assembly shaft assembly 210 extending or retracting axially into the limiting sleeve 300. For example, when the disassembly and assembly device 1000 is not in use, the working end of the disassembly and assembly shaft assembly 210 can be extended axially into the limiting sleeve 300 to avoid damage to the working end of the disassembly and assembly shaft assembly 210. When it is necessary to disassemble or assemble the radioactive source, the telescopic component 400 drives the working end of the disassembly and assembly shaft assembly 210 to extend axially out of the limiting sleeve 300 to position the radioactive source. During the disassembly of the radioactive source, the telescopic component 400 can gradually drive the working end of the disassembly and assembly shaft assembly 210, along with the radioactive source, into the limiting sleeve 300 to prevent the radioactive source from falling off when it is disconnected from the source container.

[0024] The telescopic component 400 is connected to the disassembly / assembly drive component 200. Specifically, the telescopic component 400 can be connected to the main body of the disassembly / assembly drive component 200, driving the main body of the disassembly / assembly drive component 200 to move axially relative to the limiting sleeve 300; or the telescopic component 400 can be connected to the disassembly / assembly drive component 200, directly driving the disassembly / assembly drive component 210 to move axially relative to the limiting sleeve 300. Specifically, the telescopic component 400 can be selected as one of a hydraulic cylinder, a pneumatic telescopic cylinder, or an electric push rod.

[0025] According to the embodiment of this application, the disassembly and assembly device 1000 for the radioactive source of a neutron logging instrument, in use, the telescopic member 400 drives the disassembly and assembly rotating shaft assembly 210 to move axially relative to the limiting sleeve 300, so that the working end of the disassembly and assembly rotating shaft assembly 210 extends out of the limiting sleeve 300 and cooperates with the limiting groove or positioning hole on the radioactive source. Then, the disassembly and assembly driving member 200 drives the disassembly and assembly rotating shaft assembly 210 to rotate axially, so that the radioactive source is separated from the source container. During the process of the disassembly and assembly rotating shaft assembly 210 driving the radioactive source to rotate synchronously, the telescopic member 400 can drive the disassembly and assembly rotating shaft assembly 210 to move axially synchronously into the limiting sleeve 300, so that at least part of the disassembled radioactive source can enter the limiting sleeve 300, preventing the disassembled radioactive source from falling out, and facilitating the subsequent transportation and installation of the radioactive source. After the disassembled radioactive source is transferred to the installation position, the telescopic component 400 can drive the working end of the disassembly and assembly shaft assembly 210 to extend axially relative to the limiting sleeve 300. At the same time, the disassembly and assembly drive component 200 can drive the disassembly and assembly shaft assembly 210 to rotate axially to complete the installation of the radioactive source.

[0026] like Figure 1 As shown, in some embodiments, the telescopic member 400 is connected to the end of the disassembled shaft assembly 210 opposite to the working end, and the telescopic member 400 drives the disassembled shaft assembly 210 to extend and retract relative to the limiting sleeve 300 along the axial direction.

[0027] like Figure 1 As shown, in some embodiments, the telescopic member 400 includes a cylinder 410, a piston rod 420, and a plurality of two-port solenoid valves 430. The cylinder 410 includes a fluid inlet and a fluid outlet, the two-port solenoid valves 430 are connected to the fluid inlet and the fluid outlet respectively, and the piston rod 420 is connected to the disassembly and assembly shaft assembly 210. By controlling the fluid entering and exiting the cylinder 410 through the two-port solenoid valves 430, the extension and retraction of the piston rod 420 are controlled, thereby causing the disassembly and assembly shaft assembly 210 connected to the piston rod 420 to extend or retract axially relative to the sleeve.

[0028] In some embodiments, the cylinder body 410 is selected as a pneumatic cylinder, and the gas entering and exiting the cylinder body 410 is controlled by controlling two solenoid valves 430 to control the extension and retraction of the piston rod 420. This avoids the liquid leakage and other phenomena that would occur if a hydraulic cylinder were selected.

[0029] In this embodiment, when the working end of the disassembly / removal shaft assembly 210 needs to move axially relative to the sleeve to extend and disassemble the radiation source, the connection between the two-port solenoid valve 430 and the fluid outlet is closed, and the connection between the two-port solenoid valve 430 and the fluid inlet is opened, causing the piston rod 420 to extend and retract, thereby driving the disassembly / removal shaft assembly 210 to extend axially out of the limiting sleeve 300. When the disassembly / removal device 1000 cooperates with the radiation source, the disassembly / removal drive component 200 drives the disassembly / removal shaft assembly 210 to rotate axially to separate the radiation shield from the source container. When the disassembly / removal drive component 200 drives the disassembly / removal shaft assembly 210 to rotate, the connection between the two-port solenoid valve 430 and the fluid inlet is closed, and the connection between the two-port solenoid valve 430 and the fluid outlet is opened, so that the disassembly / removal shaft assembly 210 can retract axially into the limiting sleeve 300 while disassembling the radiation source, preventing the disassembled radiation source from falling.

[0030] like Figure 1 As shown, in some embodiments, the telescopic member 400 also includes a throttle valve installed at the fluid outlet. The throttle valve controls the amount of fluid discharged from the cylinder 410, thereby controlling the movement speed of the disassembly and assembly shaft assembly 210 relative to the limiting sleeve 300.

[0031] like Figure 1As shown, in some embodiments, the disassembly / assembly drive component 200 is a hollow geared integrated servo motor, and the end of the disassembly / assembly shaft assembly 210 opposite to the working end is connected to the piston rod 420. The hollow geared integrated servo motor has high-precision position, speed, and torque control capabilities. By cooperating with the telescopic component 400, the rotation angle and speed of the disassembly / assembly shaft assembly 210 can be precisely controlled, thereby achieving precise control of the movement of the piston rod 420 and meeting the strict requirements for position and speed during the disassembly / assembly process. At the same time, the hollow structure and integrated design make the entire drive device compact and small in size. In situations where installation space is limited, this design can make full use of the limited space, facilitating the layout and installation of the equipment.

[0032] like Figure 1 As shown, in some embodiments, the disassembly and assembly shaft assembly 210 includes a shaft 211, a coupling 212, and a disassembly and assembly screw 213. The disassembly and assembly screw 213 is connected to the shaft 211 through the coupling 212 and is used to disassemble and assemble the radioactive source of the neutron logging instrument.

[0033] In this embodiment, the mounting screw 213 is detachably connected to the rotating shaft 211 via a coupling 212, allowing the mounting device 1000 to replace different types of mounting screws 213 according to the type of radiation source, thus improving the versatility of the mounting device 1000. Furthermore, when the mounting screw 213 becomes worn, damaged, or fails to meet usage requirements during use, it can be easily removed from the coupling 212 for replacement, making maintenance more convenient.

[0034] like Figure 1 As shown, in some embodiments, the disassembly and assembly device 1000 further includes a multi-axis robotic arm, a control component, and a positioning component. The end effector of the multi-axis robotic arm is connected to the frame body 100, the positioning component is installed on the frame body 100, and the control component is electrically connected to the multi-axis robotic arm and the positioning component respectively.

[0035] In this embodiment, when it is necessary to disassemble or assemble the radioactive source of the neutron logging instrument, the operator first inputs the disassembly or assembly command through the human-machine interface. After receiving the command, the control component activates the positioning component to locate the radioactive source. Based on the positioning result, the control component plans the motion trajectory of the multi-axis robotic arm and controls the multi-axis robotic arm to move according to the command, moving the working end of the disassembly / assembly shaft assembly 210 to the installation or disassembly position of the radioactive source. Then, the disassembly / assembly drive component 200 drives the disassembly / assembly shaft assembly 210 to move axially relative to the limiting sleeve 300 to extend the limiting sleeve 300, thereby disassembling the radioactive source.

[0036] Similarly, the positioning component can also locate the installation position of the radiation source, enabling the control component to control the multi-axis robotic arm to transport the disassembled radiation source to the required installation position, thereby completing the installation of the radiation source.

[0037] In some alternative embodiments, the disassembly and assembly device 1000 also includes a movable base, with the multi-axis robotic arm connected to the movable base to facilitate the transport of the disassembly and assembly device 1000.

[0038] like Figure 1 As shown, in some embodiments, the positioning component includes a ranging component 500 and an image acquisition component 600. The ranging component 500 is used to detect the distance information between the radiation source and the disassembly / assembly device 1000, and the image acquisition component 600 is used to acquire the position information of the radiation source.

[0039] The coordinated operation of the ranging component 500 and the image acquisition component 600 provides high-precision, real-time spatial location information for the assembly and disassembly of the radioactive source, ensuring safe and efficient operation.

[0040] like Figure 1 As shown, in some embodiments, the ranging component 500 includes at least one of a laser ranging sensor, an infrared ranging sensor, an ultrasonic ranging device, and a radar ranging sensor.

[0041] like Figure 1 As shown, in some embodiments, the image acquisition component 600 includes a camera, a lens, and a light source. The lens is mounted on the camera, and the light source is mounted on the frame body 100. The camera can be selected as a high-resolution industrial camera. The light source provides uniform illumination to eliminate shadows or reflections, enhance image contrast, and enable the camera to accurately capture clear images of the radiation source and transmit them to the control component.

[0042] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
