Description

Technical Field

[0001] This invention relates to the field of sample tube storage technology, and more particularly to an oil sample tube storage device. Background Technology

[0002] Oil sample tubes serve as benchmark tubes. They are used in certain stages of sample tube production and drilling operations to compare the diameter of the target tube. Typically, the required sample tubes are selected manually and then transported to a conveyor line for testing and comparison. The process of transporting sample tubes usually requires two to three workers, and the sample tubes typically weigh between 80 and 450 kg, making the transportation process inherently risky. Summary of the Invention

[0003] The purpose of this application is to provide an oil sample tube storage device to solve the aforementioned technical problems existing in the prior art.

[0004] This application is implemented as follows: This application provides an oil sample storage device, including a frame, a turntable, a first drive component, and a lifting assembly. The turntable has multiple mounting slots extending through both sides of its axial direction, distributed circumferentially along the turntable. The slot openings are located on the circumferential sidewalls of the turntable, and the mounting slots are used to install oil sample tubes. The turntable is rotatably mounted on the frame. The first drive component is connected to the turntable and drives it to rotate. The lifting assembly includes a second drive component and a movable part. The second drive component is connected between the frame and the movable part and drives the movable part to move, thereby switching the lifting assembly between a folded state and a lifted state. When the lifting assembly is in the folded state, the projection of the lifting assembly along the axial direction of the turntable onto the turntable surface is located within the area enclosed by all the mounting slots. During the process of switching the lifting assembly from the folded state to the lifted state, the movable part moves outward from the turntable, thereby lifting the oil sample tube located in one of the mounting slots to the outside of the turntable along the direction of gravity. The movable part is configured to drive the oil sample tube to move along its axial direction.

[0005] The technical solution provided in this application can achieve the following beneficial effects: In this application, a turntable is used to integrate and place oil sample tubes. The position of the oil sample tubes can be adjusted by rotating the turntable, eliminating the need for manual adjustment and making it easier to select suitable oil sample tubes. At the same time, a lifting component is configured to lift the oil sample tubes to the outside of the storage device and drive the oil sample tubes to move along their axial direction to transport the oil sample tubes to the conveyor line for testing and comparison. The entire process does not require manual control of the position of the oil sample tubes or hoisting of the oil sample tubes, thereby avoiding the risks caused by manual operation of the oil sample tubes and reducing labor costs. The transportation of oil sample tubes is achieved through the cooperation of the lifting component and the turntable, improving the convenience of using oil sample tubes.

Detailed Implementation

[0009] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0010] This application provides an embodiment of an oil sample tube storage device, which can be referred to as [reference needed]. Figure 2 As shown, the storage device includes a frame 100, a turntable 200, a first drive unit 300, and a lifting assembly 400. The frame 100 is the main structure of the storage device and serves as the mounting base for the other components. The turntable 200 is rotatably mounted on the frame 100, and the first drive unit 300 is connected to the turntable 200 to drive the turntable 200 to rotate.

[0011] The structure of turntable 200 can be referenced. Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, the turntable 200 is provided with multiple mounting slots 210 extending through both sides of its axial direction, and the multiple mounting slots 210 are distributed circumferentially along the turntable 200. The openings of the mounting slots 210 are located on the peripheral sidewalls of the turntable 200, and the mounting slots 210 are used to mount oil sample tubes 800. The oil sample tubes 800 can be assembled into the mounting slots 210, and the mounting slots 210 restrict the position of the oil sample tubes 800. At the same time, one turntable 200 can be used to mount multiple oil sample tubes 800. (See reference...) Figure 3 As shown, the oil sample tube 800 is integrated together, and the position of the oil sample tube 800 can be easily adjusted by rotating the turntable 200.

[0012] The oil sample tube 800 comes in various specifications. For example, the specifications of the oil sample tube 800 installed in each mounting slot 210 are different. According to the actual use requirements, the turntable 200 is rotated to rotate the oil sample tube 800 with the target specification to a position that is easy to remove.

[0013] The lifting assembly 400 includes a second drive member 410 and a movable part 420. The second drive member 410 is connected between the frame 100 and the movable part 420, that is, the movable part 420 is connected to the frame 100 through the second drive member 410. The second drive member 410 is a drive mechanism used to drive the movable part 420 to move, thereby allowing the lifting assembly 400 to switch between a folded state and a lifted state.

[0014] The lifting assembly 400 has a folded state and a raised state. When the lifting assembly 400 is in the folded state, its projection along the axial direction of the turntable 200 onto the surface of the turntable 200 lies within the enclosed area of ​​all the mounting slots 210. The turntable 200 is rotatable. During the rotation of the turntable 200, the lifting assembly 400 remains within the enclosed area formed by all the mounting slots 210. The oil sample tubes 800 mounted in the mounting slots 210 do not interfere with the lifting assembly 400, and the lifting assembly 400 does not affect the normal rotation of the turntable 200. The turntable 200 can be driven to rotate by the first driving component 300, changing the position of the oil sample tubes 800 mounted on the turntable 200. Simultaneously, after the oil sample tubes 800 are installed on the turntable 200, the lifting assembly 400 is located within the enclosed area of ​​multiple oil sample tubes 800, making full use of the storage device's space, thereby reducing the overall volume of the storage device and achieving a miniaturized design.

[0015] During the transition from a folded to a raised state, the movable part 420 moves outward from the turntable 200, thereby lifting the oil sample tube 800 located in one of the mounting slots 210 outward from the turntable 200 by gravity. The lifting assembly 400 is mounted on the frame 100, and its position does not change as the turntable 200 rotates. The direction of movement of the movable part 420 of the lifting assembly 400 is fixed. By rotating the turntable 200, one of the oil sample tubes 800 mounted on the turntable 200 is rotated into the movement path of the movable part 420 of the lifting assembly 400. The second drive member 410 drives the movable part 420 to move, thus lifting the oil sample tube 800 outward from the turntable 200. Furthermore, the lifting direction of the movable part 420 on the oil sample tube 800 is along the direction of gravity. The movable part 420 can support the oil sample tube 800 during the lifting process and stabilize the position of the oil sample tube 800.

[0016] Furthermore, the movable part 420 is configured to drive the oil sample tube 800 to move along its axial direction. The movable part 420 can drive the oil sample tube 800 to move it from above the turntable 200 to the conveyor line, eliminating the need for manual hoisting of the oil sample tube 800. Simultaneously, the movable part 420 can also be used to move the oil sample tube 800 from the conveyor line to above the turntable 200. During the process of the lifting assembly 400 switching from the lifting state to the folding state, the oil sample tube 800 moves synchronously into the mounting slot 210 as the movable part 420 moves, completing the return of the oil sample tube 800 to its original position.

[0017] In actual use, multiple oil sample tubes 800 of different specifications are installed on the turntable 200. After selecting the target specification oil sample tube 800, the first drive component 300 drives the turntable 200 to rotate, rotating the target specification oil sample tube 800 to the highest position of the turntable 200, so that the oil sample tube 800 is located on the moving path of the movable part 420 of the lifting component 400. At this time, the lifting component 400 is in a folded state. Then the first drive component 300 stops running, and the second drive component 410 starts running, driving the movable part 420 to move relative to the frame 100. The movable part 420 switches from the folded state to the lifting state. During the movement, the movable part 420 simultaneously drives the oil sample tube 800 located on its moving path, lifting the oil sample tube 800 outside the turntable 200 along the direction of gravity. At this time, the lifting component 400 is fully switched to the lifting state. Then the movable part 420 can be controlled to drive the oil sample tube 800 to move along its axis, and transport the oil sample tube 800 from above the turntable 200 to the conveyor line.

[0018] After the oil sample tube 800 is used, one end of the oil sample tube 800 is brought into contact with the movable part 420 to activate the movable part 420. The movable part 420 is then activated to drive the oil sample tube 800 to move along the axial direction of the oil sample tube 800, so that the entire oil sample tube 800 is moved above the storage device. Then, the lifting assembly 400 is controlled to switch from the lifting state to the folding state. As the movable part 420 moves, the oil sample tube 800, supported by the movable part 420, is reassembled into the mounting slot 210 of the turntable 200.

[0019] Different specifications of oil sample tubes 800 are installed on the turntable 200. The position of the oil sample tubes 800 is adjusted by rotating the turntable 200, and the required oil sample tube 800 is adjusted to the target position without the need for manual control of the position of the oil sample tube 800. At the same time, the lifting component 400 can also lift the oil sample tube 800 outside the turntable 200, and the moving part 420 can also drive the oil sample tube 800 to move along its axial direction to transport the oil sample tube 800 to the conveyor line for testing and comparison. The entire process does not require manual control of the position of the oil sample tube 800, which can effectively avoid the risks caused by manual control of the position of the oil sample tube 800, reduce labor costs, and fully ensure the safety of operators. At the same time, the whole process is convenient and quick, which can improve the ease of use of the oil sample tube 800.

[0020] In some embodiments, the storage device also includes a housing that covers the frame 100, as can be seen from... Figure 1 As shown, this is to protect the inside of the storage device.

[0021] In some embodiments provided in this application, reference may be made to Figures 4 to 6 As shown, the lifting assembly 400 also includes a connecting rod 430, which is arranged along the axial direction of the turntable 200, and the axial direction of the connecting rod 430 is parallel to the axial direction of the turntable 200. The connecting rod 430 is also connected to a second drive member 410, which drives the connecting rod 430 to move along its axial direction. There are multiple movable parts 420, all of which are mounted on the connecting rod 430 and arranged along the length of the connecting rod 430.

[0022] The second driving component 410 simultaneously drives multiple movable parts 420 to move via the connecting rod 430, ensuring that the movement of the multiple movable parts 420 remains synchronized. This maintains synchronized lifting of the movable parts 420 at both ends of the connecting rod 430, improving the support stability of the movable parts 420 on the oil sample tube 800. Furthermore, the more movable parts 420 there are, the stronger the support effect on the oil sample tube 800 and the better the driving effect.

[0023] For reference Figure 5As shown, the movable part 420 includes a support rod 421. One end of the support rod 421 is rotatably connected to the connecting rod 430 via a first rotating shaft 440, and the other end is used to contact the oil sample tube 800. The support rod 421 is also connected to the frame 100 via a second rotating shaft 450. One end of the second driving member 410 is rotatably connected to the frame 100 via a third rotating shaft 460, and the other end is rotatably connected to the connecting rod 430 via one of the first rotating shafts 440. The first rotating shafts 440, the second rotating shaft 450, and the third rotating shaft 460 are arranged in parallel and perpendicular to the axial direction of the connecting rod 430. The connecting rod 430 is simultaneously connected to multiple movable parts 420, that is, the connecting rod 430 is simultaneously connected to multiple support rods 421 via the first rotating shafts 440, and the second driving member 410 is rotatably connected to the connecting rod 430 via one of the first rotating shafts 440.

[0024] The second drive member 410 can drive the connecting rod 430 to move along its axial direction, and the two ends of the second drive member 410 rotate through the first rotating shaft 440 and the third rotating shaft 460 respectively to adjust the relative distance between the connecting rod 430 and the second rotating shaft 450 in the direction of gravity, thereby driving the support rod 421 to rotate around the second rotating shaft 450 so that the lifting assembly 400 switches between the folding state and the lifting state.

[0025] The support rod 421 has two ends, one of which is used to contact the oil sample tube 800, and the other end is rotatably connected to the connecting rod 430 via a first rotating shaft 440. A portion of the area between the two ends of the support rod 421 is also rotatably connected to the frame 100 via a second rotating shaft 450. The support rod 421 can rotate around the second rotating shaft 450 as its axis of rotation. Simultaneously, the first rotating shaft 440 also rotates around the second rotating shaft 450. However, since the first rotating shaft 440 is connected to the connecting rod 430, the position of the connecting rod 430 must also be adjusted to ensure that the support rod 421 can rotate smoothly around the second rotating shaft 450. Furthermore, the connecting rod 430 connects to multiple support rods 421 simultaneously; therefore, the connecting rod 430 needs to be translated as a whole to change its position to ensure that multiple support rods 421 can rotate simultaneously around the second rotating shaft 450.

[0026] As the second driving member 410 drives the connecting rod 430 to move axially, the movement of the connecting rod 430 drives the support rod 421 to rotate around the second pivot 450. Simultaneously, the connecting rod 430 must translate for the support rod 421 to rotate smoothly around the second pivot 450. During the translation of the connecting rod 430, the rotation of the second driving member 410 causes both the second driving member 410 and the frame 100 to rotate. This translation of the connecting rod 430 causes the second driving member 410 to rotate around the third pivot 460, and the second driving member 410 also rotates relative to the connecting rod 430 via the first pivot 440. Only in this way can the connecting rod 430 translate, and only then will the distance between the connecting rod 430 and the second pivot 450 change in the direction of gravity. This allows multiple support rods 421 to rotate simultaneously around the second pivot 450, changing the position of the support rods 421.

[0027] As the support rod 421 rotates, the lifting assembly 400 switches between a folded state and a lifting state. Figure 6 In the middle, the lifting assembly 400 is in a folded state. At this time, the second drive member 410 is tilted relative to the connecting rod 430, and the axis of the second drive member 410 is indicated by a dashed line. Figure 4 and Figure 5 In the middle, the lifting component 400 is in the deployed state.

[0028] The process of switching the lifting assembly 400 from the folded state to the lifting state can be found in the following reference. Figures 6 to 4 As shown, the second drive component 410 is a cylinder structure. The second drive component 410 is shortened, and the connecting rod 430 moves to the left as a whole. At the same time, it moves downward and then upward, driving the support rod 421 to rotate clockwise. The end of the support rod 421 away from the first rotating shaft 440 moves outward toward the turntable 200, and lifts the oil sample tube 800 during the movement.

[0029] The process of switching the lifting assembly 400 from the lifting state to the folding state can be found in the following reference. Figures 4 to 6 As shown, the second drive member 410 is a cylinder structure. When the second drive member 410 extends, the connecting rod 430 moves to the right as a whole, and at the same time moves downward and then upward, driving the support rod 421 to rotate counterclockwise. The end of the support rod 421 away from the first rotating shaft 440 rotates towards the turntable 200 and retracts into the enclosed area of ​​the multiple oil sample tubes 800.

[0030] In some implementation methods, reference may be made to Figure 12As shown, the movable part 420 also includes a roller 422 and a third drive component 423. The roller 422 is mounted on the end of the support rod 421 away from the first rotating shaft 440 and is used to contact the oil sample tube 800. The roller 422 directly contacts the oil sample tube 800. The third drive component 423 includes a drive motor 423a, a conveyor belt 423b, and two conveyor wheels 423c. The drive motor 423a is mounted on the support rod 421 and located on the side of the roller 422 near the second rotating shaft 450. The drive motor 423a and the roller 422 are arranged side by side. One conveyor wheel 423c is coaxially fixed with the roller 422, and the other conveyor wheel 423c is coaxially fixed with the output shaft of the drive motor 423a. The conveyor belt 423b is sleeved on the two conveyor wheels 423c. The drive motor 423a is used to drive the roller 422 to rotate, thereby driving the oil sample tube 800 to move along its axial direction. The rollers 422 and the drive motor 423a are arranged side by side. Through the cooperation of the drive motor 423a, the conveyor belt 423b and the two conveyor wheels 423c, the overall volume of the lifting assembly 400 is minimized, making it easier to use the lifting assembly 400.

[0031] The roller 422 at the end of the support rod 421 contacts the oil sample tube 800. The roller 422 is driven to rotate by the third drive member 423, thereby driving the oil sample tube 800 to move axially. In some preferred embodiments, the radial dimension of the roller 422 first decreases and then increases along its axis of rotation. The diameter of the roller 422 is smallest in the middle, making it less likely for the oil sample tube 800 to slide towards either end of the roller 422 after contact with it. Furthermore, the support rods 421 at both ends of the roller 422 can protrude relative to the roller 422, preventing the oil sample tube 800 from slipping off the ends of the roller 422.

[0032] In some embodiments, the support rod 421 includes a first sub-rod 421a and a second sub-rod 421b connected to each other, as can be seen from... Figure 12 As shown, the included angle between the first sub-rod 421a and the second sub-rod 421b is less than 180 degrees. The first sub-rod 421a is connected to the first rotating shaft 440, and the second sub-rod 421b is used to contact the oil sample tube 800. The included angle between the first sub-rod 421a and the second sub-rod 421b is less than 180 degrees, and their relative bending helps to improve the overall structural strength of the support rod 421. Moreover, the space required for the rotation of the bent support rod 421 is smaller, and the size of the enclosed area of ​​the multiple oil sample tubes 800 can be set smaller, which is conducive to the miniaturization design of the overall storage device.

[0033] For reference Figure 12As shown, in some embodiments, the support rod 421 has a mounting cavity inside, and the roller 422 and the drive motor 423a are both mounted inside the mounting cavity. Both ends of the roller 422 are rotatably mounted inside the mounting cavity, and the drive motor 423a is directly fixed inside the mounting cavity. The conveyor belt 423b and the conveyor wheel 423c are mounted on the side of the support rod 421. The support rod 421 can also be connected to a protective cover, which encloses the conveyor belt 423b and the conveyor wheel 423c.

[0034] In the embodiments provided in this application, the oil sample tube 800 is assembled in the mounting groove 210 of the turntable 200. In some preferred embodiments, two turntables 200 are provided, and a drive shaft 500 connects the two turntables 200, allowing the two turntables 200 to rotate synchronously via the drive shaft 500. The frame 100 includes a crossbeam 110, through which the drive shaft 500 passes. The crossbeam 110 can improve the overall structural stability of the frame 100. (See reference...) Figure 9 As shown.

[0035] refer to Figures 4 to 6 As shown, the connecting rod 430 and the second drive member 410 are located on one side of the crossbeam 110, the support rod 421 passes through the crossbeam 110 and extends to the other side of the crossbeam 110, and the second rotating shaft 450 is fixed to the side of the crossbeam 110 away from the connecting rod 430. By setting the crossbeam 110 to facilitate the installation of multiple second rotating shafts 450, and by centrally arranging the crossbeam 110, drive shaft 500 and connecting rod 430, the size of the storage device can be minimized.

[0036] In some optional embodiments of this application, the storage device further includes a strip 600, which can be referred to Figure 7 As shown, the stop bar 600 is fixed to the frame 100 and sleeved on the turntable 200. The stop bar 600 is used to prevent the oil sample tube 800 located in the mounting groove 210 from detaching from the mounting groove 210. The top of the stop bar 600 is provided with a passage notch, which allows the oil sample tube 800 installed in the mounting groove 210 to pass through the passage notch under the drive of the lifting assembly 400.

[0037] The turntable 200 has mounting grooves 210 on its circumference. Therefore, a stop bar 600 is needed to cooperate with the turntable 200. Even if the opening of the mounting groove 210 faces downward, and the oil sample tube 800 moves downward under gravity, the stop bar 600 can limit the oil sample tube 800 and prevent it from detaching from the turntable 200. In practice, the stop bar 600 can be made of POM material to reduce friction between the oil sample tube 800 and the stop bar 600.

[0038] The size of the passage gap should not be too large. During the rotation of the turntable 200, the oil sample tube 800 located on the lifting path of the lifting component 400 should be kept within the range corresponding to the passage gap to prevent other oil sample tubes 800 from accidentally falling out of the mounting slot 210.

[0039] There are various specifications for the oil sample tube 800. The size of the mounting groove 210 on the turntable 200 needs to be set to correspond to the oil sample tube 800. In some embodiments, the larger mounting groove 210 and the smaller mounting groove 210 are arranged alternately to balance the force on the turntable 200 and avoid excessive force on one side of the turntable 200, which would cause the entire equipment to tilt to one side.

[0040] In some embodiments provided in this application, the storage device further includes a detection component 700, the ultimate purpose of which is to detect whether the oil sample tube 800 located on the lifting path of the lifting component 400 is the target sample tube. See also... Figure 8 and Figure 11 As shown, the detection assembly 700 includes multiple proximity sensors 710 and multiple identification rods 720. All proximity sensors 710 are installed at equal intervals along the radial direction of the turntable 200 on the frame 100. All identification rods 720 are installed on the turntable 200, and each identification rod 720 corresponds to a mounting slot 210, rotating as the turntable 200 rotates. The proximity sensors 710 are used to detect the identification rods 720 at corresponding positions, and the number of proximity sensors 710 corresponding to each identification rod 720 is different.

[0041] It is understood that the proximity sensor 710 has a detection path, and objects located on its detection path can be detected. The identification rod 720 rotates with the turntable 200. When any identification rod 720 rotates into the detection path of the proximity sensor 710, the proximity sensor 710 can identify the identification rod 720. Furthermore, each identification rod 720 has a different length, and the number of proximity sensors 710 that can detect each identification rod 720 is also different. The length of the identification rod 720 can be determined by the number of detection results from all proximity sensors 710, thereby distinguishing multiple identification rods 720 and thus identifying the corresponding oil sample tube 800 in the mounting slot 210, making it easier to select the oil sample tube 800.

[0042] In some preferred embodiments, the detection path of the proximity sensor 710 is located at its top, that is, the proximity sensor 710 is used to detect the identification rod 720 corresponding to the oil sample tube 800 located on the lifting path of the lifting assembly 400, and to determine whether the oil sample tube 800 is the target sample tube by judging the length of the identification rod 720.

[0043] In some embodiments, the detection component 700 is mounted on one side of the turntable 200. In other embodiments, when the storage device includes two turntables 200, all proximity sensors 710 are divided into two groups, with the two groups of proximity sensors 710 located on both sides of the two turntables 200 respectively, and all identification rods 720 are divided into two groups, with the two groups of identification rods 720 located on both sides of the two turntables 200 respectively.

[0044] The proximity sensors 710 need to be installed at equal intervals along the axis of the turntable 200 on the frame 100. The more mounting slots 210 there are, the more proximity sensors 710 there are, and the larger the installation space required. By dividing the proximity sensors 710 into two groups, the space on both sides of the two turntables 200 can be fully utilized, so that the size of the storage device can be made as small as possible.

[0045] A photoelectric sensor is also installed on the transport path of the oil sample tube 800 to detect the position of the oil sample tube 800, so as to transport the oil sample tube 800 to the transport line or transport the oil sample tube 800 from the transport line back to the storage device.

Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
