[0001] The utility model relates to the technical field of filter element replacement, in particular to a filter element disassembly tool. Background Art

[0002] At key hubs such as the first station, distribution station and gate station of natural gas transmission stations, natural gas filters are important devices to ensure the quality and safety of natural gas. Their performance and stability are directly related to the normal operation of the entire gas transmission system. In order to ensure the purity and quality of natural gas, the filter elements in the natural gas filters need to be replaced regularly.

[0003] However, in practical applications, Figure 5 Due to the smooth surface of the filter element, it is difficult for operators to directly grasp the filter element firmly with their hands to remove it. As a result, the filter element in the natural gas filter equipment is often difficult to remove after installation. This not only increases the difficulty of maintenance, but may also affect the normal operation of the gas transmission station. Utility Model Content

[0007] According to the filter element disassembly tool of the embodiment of the utility model, the end of the clamp arm away from the handle is placed inside the filter element, and the connecting rod is pushed, so that the opening between the two clamp arms gradually increases until the two clamp arms are opened and inserted into the filter element, thereby firmly fixing the filter element and keeping the connecting rod immobile. Finally, the handle is held and pulled out to complete the removal of the filter element. The whole process does not require complex tools or complicated steps, but can be completed with simple operations. This not only greatly improves the efficiency of filter element removal, but also effectively reduces the difficulty of maintenance work, ensuring the normal operation of the gas transmission station.

DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] The filter element disassembly tool of the embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, the filter element disassembly tool of the first embodiment of the utility model comprises two clamping arms 1 , and each clamping arm 1 is provided with a first through groove 12 .

[0029] The connecting rod 2 and the two clamping arms 1 are connected to the connecting rod 2 through the first fastening components 3 respectively, and the two first fastening components 3 respectively penetrate the corresponding first through slots 12 and are slidably connected in the first through slots 12 .

[0030] It can be understood that by pushing the connecting rod 2, the size of the opening between the two clamping arms 1 can be changed, which can not only adapt to filter elements of different diameters and improve the application range of the filter element removal tool, but also enable maintenance personnel to easily insert the end of the clamping arm 1 away from the handle 5 into the filter element. The whole process is easy to operate and quick to install, without complicated adjustments or additional tools, which effectively improves the efficiency and convenience of maintenance work.

[0031] It should be noted that by adjusting the clamping force of the first fastening component 3, the dynamic relationship between the clamping arm 1 and the connecting rod 2 can be adjusted. When the opening size between the two clamping arms 1 needs to be adjusted, it is only necessary to appropriately reduce the clamping force of the first fastening component 3. At this time, the connecting rod 2 can slide freely in the first through groove 12, driving the clamping arm 1 to expand or contract accordingly. If the clamping force of the first fastening component 3 is increased, the connecting rod 2 cannot be pushed, which means that the opening of the two clamping arms 1 after opening is fixed.

[0032] The two clamp arms 1 are connected to the handle 5 through the second fastening assembly 4 respectively, and the clamp arms 1 are rotatable relative to the handle 5 . The connecting rod 2 is arranged between the opening between the two clamp arms 1 and the handle 5 .

[0033] Specifically, during the maintenance of the natural gas filter, the maintenance personnel need to disassemble the filter element in the natural gas filter. The relevant personnel insert the end of the clamp arm 1 away from the handle 5 into the interior of the filter element. The relevant personnel holds the handle 5 as a fulcrum with one hand, and pushes the connecting rod 2 into the interior of the filter element with the other hand. The movement of the connecting rod 2 gradually increases the opening between the two clamp arms 1 until the two clamp arms 1 open and penetrate into the filter element, thereby firmly fixing the filter element. Finally, the relevant personnel keeps the hand pushing the connecting rod 2 still, and the hand holding the handle 5 moves in coordination with the body (in the direction away from the filter element), thereby pulling out the filter element.

[0034] In another case, if the filter element is difficult to remove with one hand due to some reasons (for example, jamming during later disassembly due to improper installation), the maintenance personnel can adjust the clamping force of the first fastening component 3 so that the connecting rod 2 is firmly fixed on the clamping arm 1. At this time, the positions of the two clamping arms 1 that are opened and inserted into the filter element remain fixed. In this way, the hand originally used to push the connecting rod 2 is freed, and the maintenance personnel can hold the handle 5 with both hands and apply greater pulling force, thereby overcoming the resistance more easily and smoothly removing the filter element.

[0035] The whole process does not require complicated tools or tedious steps, but can be completed with simple operations. This not only greatly improves the efficiency of filter element removal, but also effectively reduces the difficulty of maintenance work and ensures the normal operation of the gas transmission station.

[0036] In one embodiment of the present invention, Figure 1 As shown, a sharp hook 10 is integrally formed on one end of the clamp arm 1 away from the handle 5 .

[0037] Among them, it can be understood that by setting the sharp hook 10 as above, the clamp arm 1 can more firmly grasp the surface or internal structure of the filter element when inserted into the filter element, thereby increasing the friction and gripping force between the inside of the filter element, making the disassembly process more stable and reliable, thereby improving the disassembly efficiency of the filter element.

[0038] In order to further clarify the above embodiment, in one embodiment of the present utility model, as shown in FIG. Figure 1 As shown, the hook tips of the two pointed hooks 10 face opposite directions.

[0039] Among them, it can be understood that the hook tips of the two sharp hooks 10 are facing oppositely, so that the sharp hooks 10 are facing the inner wall of the filter element, which can form a multi-point fixing effect. This design makes the connection between the clamp arm 1 and the filter element more stable, and reduces the risk of the filter element disassembly tool falling off due to uneven force during the disassembly process. Moreover, since the hook tips are facing oppositely, the two sharp hooks 10 can balance each other when subjected to force, further enhancing the stability between the clamp arm 1 and the filter element.

[0040] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, two second through holes 20 are formed on the connecting rod 2 , and the two second through holes 20 correspond to the two first through slots 12 one by one, respectively, and the second through holes 20 and the first through slots 12 are connected via a first fastening assembly 3 .

[0041] Specifically, by using the first fastening component 3 to penetrate the first through groove 12 and the second through hole 20, the connection between the connecting rod 2 and the clamping arm 1 can be quickly achieved, which simplifies the assembly process of the filter element disassembly tool. The parts can be separated and assembled without complicated tools or cumbersome steps, making maintenance work more flexible and efficient.

[0042] In order to further clarify the above embodiment, in one embodiment of the present utility model, as shown in FIG. Figure 1 As shown, the first fastening assembly 3 includes a first bolt 30 and a first nut 31 .

[0043] The bolt head of the first bolt 30 is attached to the clamp arm 1 , and the screw rod of the first bolt 30 passes through the first through groove 12 and the second through hole 20 and is threadedly connected to the first nut 31 .

[0044] Specifically, the first nut 31 and the first bolt 30 can limit the position of the clamp arm 1 and the connecting rod 2 , and the state between the clamp arm 1 and the connecting rod 2 can be adjusted by adjusting the clamping force between the first nut 31 and the first bolt 30 .

[0045] If the clamping force between the clamp arm 1 and the connecting rod 2 is relatively small when the first nut 31 cooperates with the first bolt 30, one hand can push the connecting rod 2 so that the connecting rod 2 pushes the first bolt 30 to slide in the first through groove 12, thereby lowering the two clamp arms 1 to open and fix the filter element. When removing the filter element, hold the handle 5 with the other hand and move the body away from the filter element to disassemble the filter element.

[0046] Furthermore, if the filter element is difficult to remove with one hand due to some reasons (such as getting stuck during assembly), the maintenance personnel can increase the clamping force between the first nut 31 and the first bolt 30 by rotating the first nut 31, thereby fixing the opening angle of the two clamp arms 1. There is no need to fix the position of the connecting rod 2 by hand. At this time, both hands can be completely released, and the handle 5 can be fully grasped and force can be applied outward to efficiently and stably complete the removal of the filter element, thereby significantly improving maintenance efficiency and operational convenience.

[0047] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the handle 5 is a hollow steel tube.

[0048] Among them, it can be understood that by designing the handle 5 as a hollow steel tube with a lighter weight than a solid steel tube, the filter element disassembly tool is lighter when used, reduces the user's sense of weight, and improves comfort when used. The hollow steel tube is round, which can further improve the comfort of maintenance personnel when holding the handle 5.

[0049] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, a first through hole 11 is provided on one end of the clamp arm 1 adjacent to the handle 5, second through slots 51 are respectively provided at both ends of the handle 5, and four third through holes 50 are provided on the outer wall of the handle 5, each second through slot 51 is adjacent to two oppositely arranged third through holes 50, one end of the clamp arm 1 is inserted into the corresponding second through slot 51, and the two opposite third through holes 50 are connected to the corresponding first through holes 11 via a second fastening assembly 4.

[0050] It can be understood that by providing the second through slot 51, one end of the clamp arm 1 can be easily inserted between the two third through holes 50, and the second through slot 51 can also limit the clamp arm 1, effectively reducing unnecessary shaking or deviation, thereby improving the stability of the clamp arm 1 when rotating.

[0051] In order to further clarify the above embodiment, in one embodiment of the present utility model, as shown in FIG. Figure 1 As shown, the second fastening assembly 4 includes a second bolt 40 and a second nut 41 .

[0052] Among them, the bolt head of the second bolt 40 is attached to the outer wall of the handle 5, the screw rod of the second bolt 40 passes through two oppositely arranged third through holes 50 and the first through hole 11 located between the two oppositely arranged third through holes 50, the second nut 41 is threadedly connected to the screw rod passing through the second bolt 40, and the second nut 41 is attached to the outer wall of the handle 5.

[0053] Specifically, through the above arrangement, the clamp arm 1 is sleeved on the second bolt 40, and the second bolt 40 is used in conjunction with the second nut 41 to limit the clamp arm 1. When the connecting rod 2 is pushed, the clamp arm 1 can rotate with the second bolt 40 as the origin, thereby ensuring the stability of the clamp arm 1 during rotation. When the clamp arm 1 is hooked into the filter element, the connecting rod 2 and the handle 5 can play a double-point support role for the clamp arm 1, thereby improving the stability and reliability of the clamp arm 1 when hooking the filter element and pulling it out.

[0054] In one embodiment of the present invention, the connecting rod 2 and the handle 5 are respectively wrapped with grip sleeves (not shown in the figure).

[0055] It can be understood that the provision of the grip sleeve can increase the comfort of the hand holding the handle 5, while optimizing the hand feel when pushing the connecting rod 2, reducing the direct contact between the hand and the connecting rod 2, and reducing friction and discomfort.

[0056] In summary, the filter element disassembly tooling of the embodiment of the utility model has a compact structure and is easy to operate, which not only greatly improves the efficiency of filter element disassembly, but also effectively reduces the difficulty of maintenance work and ensures the normal operation of the gas transmission station.
