Technical Field

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

[0002] During well logging, when a density logging instrument is needed, the radioactive source must be removed from the source chamber and installed onto the instrument. After logging is complete, the radioactive source must be removed from the density logging instrument. Currently, the placement, removal, and disassembly of radioactive sources are usually done manually. Because radioactive sources have a certain radiation effect on the human body, manually placing, removing, and disassembling radioactive sources from density logging instruments increases the health risks for operators. Utility Model Content

[0004] This application provides a device for disassembling and assembling a radioactive source for a density logging instrument, comprising: a radioactive source clamp, including a housing, a limiting member, and a threading tool; the limiting member is mounted on the housing and can limit the radioactive source to be disassembled or assembled; the threading tool can be threadedly connected to the radioactive source to be disassembled or assembled; a first driving component, installed inside the housing, and drivenly connected to the threading tool; a second driving component, detachably connected to the housing; a positioning component, capable of acquiring the position information of the radioactive source to be disassembled or assembled; and a control component, electrically connected to the first driving component, the second driving component, and the positioning component, respectively.

The end face of the limiting end is provided with a first limiting portion and a second limiting portion at intervals, and at least a portion of the radiation source to be disassembled can be accommodated between the first limiting portion and the second limiting portion.

[0006] According to any of the foregoing embodiments of this application, a first limiting portion and a second limiting portion provided at intervals form a limiting groove, the shape of which matches at least a portion of the outer contour shape of the radiation source to be disassembled.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] This application provides a device for disassembling and assembling radioactive sources for density logging instruments, which can automatically complete the operation process of picking up, placing, installing and disassembling radioactive sources for density logging instruments, avoiding the risk of operators directly contacting radioactive sources, ensuring the health and safety of operators, and improving the automation and intelligence of disassembling and assembling radioactive sources for density logging instruments.

[0025] like Figure 1-2 As shown in the illustration, this application provides a density logging instrument radioactive source disassembly and assembly device 1000. The device includes a radioactive source clamp 100, a first drive assembly 200, a second drive assembly, a positioning assembly 300, and a control assembly. The radioactive source clamp 100 includes a housing 110, a limiting member 120, and a threading tool 130. The limiting member 120 is mounted on the housing 110 and can limit the radioactive source to be disassembled or assembled in its circumferential direction. The threading tool 130 can be threadedly connected to the radioactive source to be disassembled or assembled. The first drive assembly 200 is installed inside the housing 110 and is drivenly connected to the threading tool 130. The second drive assembly is detachably connected to the housing 110. The positioning assembly 300 can acquire the position information of the radioactive source to be disassembled or assembled. The control assembly is electrically connected to the first drive assembly 200, the second drive assembly, and the positioning assembly 300, respectively.

[0026] It should be noted that in this embodiment, the limiting member 120 can be a limiting sleeve 121 or a limiting gripper, etc., as long as it can limit the circumference of the radiation source to be disassembled and installed, and allow it to rotate during the disassembly and installation process.

[0027] The first drive assembly 200 drives the threading tool 130 to rotate, so that the threading tool 130 and the threaded hole of the radiation source M to be disassembled are threaded together. The first drive assembly can be a servo motor 210 assembly or a stepper motor, etc. The servo motor 210 assembly or the stepper motor drives the threading tool 130 to rotate so as to screw into the threaded hole of the radiation source M to be disassembled.

[0028] The second drive assembly is used to position the limiting member 120 and the threading tool 130 of the radiation source clamp 100 with the radiation source to be disassembled or assembled. The second drive assembly can be a multi-axis mechanical wall or a robotic arm.

[0029] The positioning component 300 can be a camera or other imaging component to collect image information or position coordinate information of the radiation source to be disassembled or assembled, so that the control component can control the first drive component 200 and the second drive component to work based on the collected information.

[0030] In this embodiment, when the radioactive source of the density logging instrument needs to be disassembled or assembled, the positioning component 300 first collects its position information, and then sends the collected position information of the radioactive source to be disassembled or assembled to the second drive component. The second drive component can drive the radioactive source clamp 100 to move to the radioactive source to be disassembled or assembled, so that the threading tool 130 can be positioned with the threaded hole of the radioactive source to be disassembled or assembled. At the same time as the threading tool 130 is positioned with the radioactive source to be disassembled or assembled, the limiting member 120 can circumferentially limit the radioactive source to be disassembled or assembled to prevent the limiting member 120 from rotating along the axial direction of the threading tool 130 with the radioactive source to be disassembled or assembled during the disassembly or assembly process. Then the control component controls the second drive component to drive the threading tool 130 to rotate, so that the threading tool 130 can engage with the radioactive source to be disassembled or assembled, thereby completing the disassembly or assembly of the radioactive source to be disassembled or assembled.

[0031] like Figure 1-2 As shown, in some embodiments, the limiting member 120 includes a limiting sleeve 121. The limiting sleeve 121 has a fixed end 121a and a limiting end 121b arranged axially opposite to each other. The fixed end 121a is fixedly connected to the housing 110. The limiting end 121b protrudes from the housing 110. A first limiting portion T1 and a second limiting portion T2 are spaced apart on the end face of the limiting end 121b, and at least a portion of the radiation source to be disassembled can be accommodated between the first limiting portion T1 and the second limiting portion T2.

[0032] It should be noted that in this embodiment, the threading tool 130 is disposed inside the limiting sleeve 121, and the working end of the threading tool 130 is disposed between the first limiting part T1 and the second limiting part T2. Of course, it can be understood that the threading tool 130 can also be disposed outside the limiting sleeve 121, as long as the first limiting part T1 and the second limiting part T2 of the limiting member 120 can circumferentially limit the radiation source to be disassembled after the threaded hole of the threading tool 130 and the radiation source to be disassembled are positioned. The relative positional relationship between the limiting member 120 and the threading tool 130 is not limited.

[0033] In this embodiment, the limiting sleeve 121 is disposed on the outside of the housing 110, and the fixed end 121a is fixedly connected to the housing 110 of the radioactive source clamp 100. The first limiting part T1 and the second limiting part T2 of the limiting end 121b are spaced apart. After the radioactive source clamp 100 and the threaded tool 130 to be disassembled are positioned, at least a part of the radioactive source to be disassembled is clamped between the first limiting part T1 and the second limiting part T2, so that during the process of the threaded tool 130 being screwed into the threaded hole of the radioactive source to be disassembled, the first limiting part T1 and the second limiting part T2 can restrict the circumferential rotation of the radioactive source to be disassembled.

[0034] like Figure 1-2 As shown, in some embodiments, a first limiting portion T1 and a second limiting portion T2, which are spaced apart, form a limiting groove, the shape of which matches at least a portion of the outer contour shape of the radiation source to be disassembled.

[0035] In this embodiment, the first limiting part T1 and the second limiting part T2 form a limiting groove. The sidewall of the limiting groove can restrict the circumferential rotation of the radiation source to be disassembled, and the bottom of the limiting groove can limit the radiation source to be disassembled in the axial direction of the limiting sleeve 121 when the limiting member 120 is engaged with the radiation source to be disassembled, so that the limiting member 120 and the radiation source to be disassembled can better engage. At the same time, the shape of the limiting groove matches at least part of the outer contour shape of the radiation source to be disassembled, further improving the engagement degree between the limiting member 120 and the radiation source to be disassembled.

[0036] like Figure 1-2 As shown, in some embodiments, the threading tool 130 is disposed inside the limiting sleeve 121, and the threading tool 130 and the limiting sleeve 121 are coaxially disposed.

[0037] In this example, the threading tool 130 is disposed within the limiting sleeve 121, and the threading tool 130 and the limiting sleeve 121 are coaxially arranged. On the one hand, the threading tool 130 is protected and dustproofed within the limiting sleeve 121. On the other hand, the placement of the threading tool 130 within the limiting sleeve 121 allows for better positioning of the limiting sleeve 121, the threading tool 130, and the radiation source to be disassembled. Furthermore, because the threading tool 130 and the limiting sleeve 121 are coaxial, the limiting force exerted by the limiting sleeve 121 on the radiation source to be disassembled is relatively balanced when the threading tool 130 engages with the radiation source.

[0038] like Figure 1-2 As shown, in some embodiments, the positioning component 300 includes an image acquisition component 310 and a ranging component 320, both of which are installed inside the housing 110.

[0039] In this embodiment, the positioning component 300 includes an image acquisition component 310 and a ranging component 320. Specifically, the image acquisition component 310 may include an industrial camera and a lens to acquire image position information of the radiation source to be disassembled. The ranging component 320 is used to detect the distance information between the device and the radiation source to be disassembled.

[0040] like Figure 1-2 As shown, in some embodiments, the image acquisition component 310 includes a camera, a lens, and a light source, with the lens and the light source respectively connected to the camera.

[0041] In this embodiment, the light source can provide illumination for the camera during image acquisition, thereby improving the image quality captured by the camera.

[0042] like Figure 1-2 As shown, in some embodiments, the ranging component 320 includes one of a laser rangefinder, an infrared rangefinder, and a radar rangefinder.

[0043] It should be noted that the image acquisition component 310 and the ranging component 320 can be installed inside or outside the housing 110 of the radiation source clamp 100. In this embodiment, it is preferred that the image acquisition component 310 and the ranging component 320 be installed inside the housing 110. The housing 110 has corresponding acquisition holes. On the one hand, the interior of the housing 110 can provide a certain degree of protection and dust prevention for the image acquisition component 310 and the ranging component 320. On the other hand, it can reduce the overall size of the device and make the shape and structure of the device more compact.

[0044] like Figure 1-2As shown, in some embodiments, the first drive assembly 200 includes a servo motor 210, which is installed inside the housing 110, and the drive shaft of the servo motor 210 is coaxially connected to the threaded tool 130 via a coupling.

[0045] In this embodiment, the servo motor 210 is installed inside the housing 110. The drive shaft of the servo motor 210 is coaxially connected to the thread tool 130 through a coupling, which drives the thread tool 130 to rotate axially to screw into the threaded hole of the radiation source to be disassembled and connected to the radiation source by thread. This allows the radiation source clamp 100 to grab the radiation source to be disassembled and disassemble the radiation source.

[0046] like Figure 1-2 As shown, in some embodiments, the density logging instrument radioactive source disassembly and assembly device 1000 further includes a multi-axis mechanical wall connected to the housing 110. The multi-axis mechanical wall is connected to the housing 110 of the radioactive source clamp 100 to drive the limiting member 120 and the threading tool 130 of the radioactive source clamp 100 to move, so as to position it with the radioactive source to be disassembled.

[0047] In some embodiments, the density logging instrument radioactive source disassembly and assembly device 1000 further includes a movable platform on which a multi-axis robotic arm is mounted. This makes the movement and transport of the disassembly and assembly device more convenient. In some optional embodiments, the movable platform further includes a third drive assembly electrically connected to a control assembly to control the third drive assembly to move the movable platform.

[0048] 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.
