Technical Field

[0001] This utility model relates to the field of filter cartridge delivery technology, and in particular to a quick-change and lightweight delivery device for filter cartridges in a plant. Background Technology

[0002] As the first step in the natural gas supply process, filtration is primarily used to remove impurities, moisture, and particulate matter from the gas to ensure gas quality and supply safety. During gas transmission, storage, and use, the regular replacement of filter elements is crucial for maintaining their proper function and extending their service life. Therefore, a convenient, quick-change device for dispensing filter elements at the gas station is needed.

[0003] The quick-change lightweight delivery device for filter cartridges in a facility is a device specifically designed for the rapid replacement of filter cartridges in facility environments. Traditional filter cartridge replacement methods often require workers to manually carry heavy filter cartridges, which not only increases the labor intensity of workers but may also lead to low work efficiency and safety hazards. In addition, previous delivery devices often adopted an integrated design with a fixed overall height, resulting in poor overall versatility and compatibility, and making them unsuitable for various types and specifications of filter cartridges. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a quick-change lightweight delivery device for station filter cartridges, which aims to improve the problem that previous delivery devices often adopted an integrated design with a fixed overall height, resulting in poor overall versatility and compatibility.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A portable quick-change filter cartridge delivery device for a plant includes a semi-circular base. A second fixed guide groove and a first fixed support are fixedly connected to the inner wall of the semi-circular base. A threaded movable component is slidably connected inside the second fixed guide groove. A threaded screw is threaded inside the threaded movable component. A threaded adjusting nut is threaded to the outer wall of the threaded screw. A reverse threaded screw is threaded to the inner thread of the threaded adjusting nut. A reverse threaded fixing component is threaded to the outer wall of the reverse threaded screw. A second support rod is rotatably connected to the outer wall of the reverse threaded fixing component. A stabilizing screw is rotatably connected to the inner wall of the second support rod. A first support rod is rotatably connected to the outer wall of the stabilizing screw. A second fixed support is rotatably connected to the outer wall of the first support rod. A semi-circular support plate is fixedly connected to the outer wall of the second fixed support. A first fixed guide groove is fixedly connected to the outer wall of the semi-circular support plate. A connecting assembly is provided on the outer wall of the threaded screw to assist in the rotation of the threaded screw.

[0007] Preferably, the connecting assembly includes a universal coupling, the outer wall of which is fixedly connected to the outer wall of the spur threaded rod, and a push rod is provided on the outer wall of the universal coupling.

[0008] Preferably, the inner wall of the semi-circular support plate is slidably connected to an extension support plate.

[0009] Preferably, the extended support plate has a fixing nut connected to its internal thread.

[0010] Preferably, the outer wall of the fixing nut is threaded into the interior of the semi-circular support plate.

[0011] Preferably, the outer wall of the semi-circular base is fixedly connected with a directional wheel.

[0012] Preferably, the outer wall of the reverse tooth fixing member is rotatably connected to the inside of the first fixed support.

[0013] Preferably, the interior of the first fixed guide groove is slidably connected to the outer wall of the second support rod.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, by rotating the hand push rod, the universal coupling is driven to rotate, which in turn drives the spur screw to rotate. The spur screw movable part drives one end of the first support rod to move, thereby causing the second fixed support to move upward. Then, the second support rod is pulled to rotate on the first fixed support through the first fixed guide groove, thus achieving the effect of adjusting the height of the semi-arc support plate as needed.

[0016] 2. In this utility model, by tightening the fixing nut, the extension support plate can be installed and disassembled as needed. When the extension support plate is not needed, it can be disassembled to save storage space and reduce the size and weight of the device, making it easy to carry and transport. At the same time, it also achieves the effect of making the filter element stable inside filters of various sizes. Attached Figure Description

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a quick-change and lightweight delivery device for station filter cartridges, comprising a semi-arc base 1. A second fixed guide groove 16 and a first fixed support 18 are fixedly connected to the inner wall of the semi-arc base 1. A slidable orthogonal threaded movable part 14 is slidably connected inside the second fixed guide groove 16. A slidable threaded lead screw 6 is threaded inside the slidable movable part 14. A slidable / reverse threaded adjusting nut 8 is threaded to the outer wall of the slidable threaded lead screw 6. A reverse threaded lead screw 7 is threaded to the inner wall of the slidable lead screw 7. A reverse threaded fixing part 15 is threaded to the outer wall of the reverse threaded fixing part 15. A second support rod is rotatably connected to the outer wall of the reverse threaded fixing part 15. 19. The inner part of the second support rod 19 is rotatably connected to a stabilizing screw 13. The outer wall of the stabilizing screw 13 is rotatably connected to a first support rod 9. The outer wall of the first support rod 9 is rotatably connected to a second fixed support 10. The outer wall of the second fixed support 10 is fixedly connected to a semi-circular support plate 2. The outer wall of the semi-circular support plate 2 is fixedly connected to a first fixed guide groove 11. The outer wall of the spur threaded rod 6 is provided with a connecting assembly, which is used to assist the rotation of the spur threaded rod 6. The connecting assembly includes a universal coupling 5. The outer wall of the universal coupling 5 is fixedly connected to the outer wall of the spur threaded rod 6. The outer wall of the universal coupling 5 is provided with a push rod 4.

[0025] Specifically, the semi-circular base 1 supports and fixes the second fixed guide groove 16 and the first fixed support 18. By rotating the push rod 4, connected by the universal coupling 5, it drives the spur threaded rod 6 to rotate in the spur threaded movable part 14. The spur threaded rod 6 drives the reverse threaded rod 7 to rotate in the reverse threaded fixed part 15 through the spur threaded adjustment nut 8. The stabilizing screw 13 supports and limits the first support rod 9 and the second support rod 19, thereby improving the support of the first support rod 9 and the second support rod 19. The second fixed support 10 and the second fixed guide groove 16 limit the first support rod 9.

[0026] Reference Figure 3 and Figure 4 An extension support plate 12 is slidably connected to the inner wall of the semi-circular support plate 2; a fixing nut 17 is threadedly connected to the inside of the extension support plate 12; and the outer wall of the fixing nut 17 is threadedly connected to the inside of the semi-circular support plate 2.

[0027] Specifically, the extension support plate 12 can be installed onto the semi-circular support plate 2 as needed via the fixing nut 17, which serves to connect the extension support plate 12 and the semi-circular support plate 2.

[0028] Reference Figure 1 - Figure 4 The outer wall of the semi-circular base 1 is fixedly connected to the directional wheel 3; the outer wall of the reverse tooth fastener 15 is rotatably connected to the inside of the first fixed support 18; the inside of the first fixed guide groove 11 is slidably connected to the outer wall of the second support rod 19.

[0029] Specifically, the directional wheel 3 assists in pushing the whole unit to the appropriate position for installation, and the first fixed support 18 limits the reverse-tooth fixing part 15. The first fixed guide groove 11 and the first fixed support 18 limit the second support rod 19.

[0030] Working principle: When the device is needed, firstly, the entire assembly is pushed to the appropriate position for installation using the directional wheel 3. Then, by rotating the hand push rod 4, the universal coupling 5 is rotated, causing the spur threaded rod 6 to rotate. This rotation is then transmitted to the spur threaded adjustment nut 8, which in turn rotates the reverse threaded rod 7. During clockwise rotation, the spur threaded movable part 14 slides along the second fixed guide groove 16 on the semi-circular base 1 in the direction parallel to the spur threaded rod 6. This causes one end of the first support rod 9 to move via the spur threaded movable part 14. At this time, the other end of the first support rod 9 experiences an upward force during the movement, causing the second fixed support 10 on the upper semi-circular support plate 2 to move upward. The semi-circular support plate 2 then pulls the second support rod 19 on the first fixed support 18 through the first fixed guide groove 11, thereby rotating the entire semi-circular support plate 2. The extended support plate 2 moves upward, and to lower it, simply rotate the push rod 4 counterclockwise according to the above steps and tighten the fixing nut 17. This allows for the installation and removal of the extended support plate 12 as needed. This device not only achieves the effect of adjusting the height of the semi-circular support plate 2 as needed, thus ensuring that the filter element can be placed and removed easily and stably, thereby simplifying the replacement process and improving work efficiency, but also ensures that the filter element maintains a horizontal or stable posture during replacement and use, reducing potential damage or safety issues caused by shaking or tilting. It also achieves the effect of installing and removing the extended support plate 12 as needed. Depending on the specific location of the filter element or the working environment, the extended support plate 12 can be installed or removed to adapt to different height or space limitations, thereby ensuring that the filter element can be replaced smoothly and that the filter element can be stably installed inside filters of various sizes.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
