Description
Technical Field
[0001] This utility model relates to the field of aviation fuel filtration equipment maintenance technology, and in particular to a tool for disassembling and assembling fuel filter separator elements. Background Technology
[0002] Aviation fuel filters are primarily used to filter impurities and moisture from aviation fuel during the fuel receiving and dispensing processes, and are crucial equipment for ensuring the quality of aviation fuel. With the rapid development of the aviation industry, the supply of aviation fuel from airport fuel depots has increased dramatically, leading to a corresponding increase in the number of fuel pumps and the corresponding fuel filter separators downstream of these pumps. According to industry standards, fuel filter separators require regular inspection and cleaning to ensure their proper functioning.
[0003] In the existing technology, the filter element of the oil filter separator is usually designed as a double layer. During the maintenance of the oil filter separator, the staff needs to remove the upper filter element and the lower filter element in turn to complete the inspection and cleaning of the filter element. However, due to the large size of the fuel filter separator (inner wall height exceeding 2m) and the fact that a single filter element is approximately 110cm high and 15cm in diameter, workers face numerous problems when handling filter elements (especially the lower filter elements): First, operation is difficult; it is hard to directly remove the filter elements, and workers must insert their upper bodies into the fuel filter separator to reach the lower filter elements. If their arm length is insufficient, disassembly is difficult. Second, there are safety hazards; workers can easily inhale volatile aviation fuel vapors after entering the fuel filter separator, posing a risk of poisoning and harming their health. Third, the filter elements are easily damaged; because the surface of the filter elements is covered with aviation fuel and is relatively smooth, it is easy for workers to slip when handling them, resulting in damage, and retrieval after falling is difficult. Fourth, installation efficiency is low; after maintenance, the filter elements need to be precisely aligned with the clamps at the bottom of the fuel filter separator for secure installation, but due to the limited working space, workers' operation is restricted, thus reducing installation efficiency.
[0004] Therefore, there is an urgent need to design a tool for disassembling and assembling oil filter elements to facilitate the disassembly and assembly of filter elements inside the oil filter separator, especially suitable for the disassembly and assembly of lower filter elements. Utility Model Content
[0005] The purpose of this utility model is to overcome the defects of the existing technology and provide a tool for disassembling and assembling oil filter separators that can facilitate workers to quickly and safely disassemble and install the filter element, improve disassembly and assembly efficiency, and ensure the safety of personnel.
[0006] To achieve the above objectives, this utility model provides a tool for disassembling and assembling an oil filter separator element, comprising a rod, a handle, a connector, and a clamping assembly. The clamping assembly includes two clamping blocks, which are movably mounted on one end of the rod. The handle is located at the other end of the rod and has a switch. The connector is connected to the switch and the two clamping blocks respectively, so that the two clamping blocks can be moved closer or further apart through the switch and the connector.
[0007] Preferably, the rod body is hollow, the connector passes through the rod body, the clamping assembly further includes a sleeve, one end of the sleeve is detachably connected to the rod body, and the other end of the sleeve is an open end that gradually widens from top to bottom, and the two clamping blocks are movably installed on the open end through the connector.
[0008] Preferably, the sidewalls of the two clamping blocks are respectively formed with slopes adapted to the open end.
[0009] Preferably, a plurality of limiting grooves are provided on the outer wall of the open end, and the plurality of limiting grooves are respectively provided for the two clamping blocks. The extension direction of the plurality of limiting grooves is consistent with the inclination direction of the slope on the two clamping blocks, and the two clamping blocks are respectively provided with positioning posts passing through the limiting grooves.
[0010] Preferably, the two clamping blocks have grooves on opposite sides, the two grooves form a clamping space for the filter element to extend into, and the bottom of the two grooves is provided with an anti-slip pad.
[0011] Preferably, the connector is a pull rope, one end of the sleeve is sleeved on the rod body, a locking hole is provided on the outer wall of the sleeve, and a fastener that abuts against the rod body is provided in the locking hole.
[0012] Preferably, a plurality of support rods are formed evenly and at intervals along the circumference of the end of the rod away from the handle, and each of the plurality of support rods is provided with a clamping assembly.
[0013] Beneficial effects:
[0014] 1. In this utility model, a tool for disassembling and assembling an oil filter separator element is provided. The rod body is adapted to the installation depth of the filter element. The operator only needs to operate the switch to make the two clamping blocks at the far end of the rod body clamp or release the filter element to complete the disassembly and assembly operation. There is no need for the operator to reach into the oil filter separator. The rod body significantly extends the operating range and overcomes the limitation of the operator's insufficient arm length causing difficulties in disassembling and assembling the filter element. It is especially suitable for disassembling and assembling the lower layer filter element in the oil filter separator.
[0015] 2. In the use of this utility model, an oil filter separator filter element disassembly and assembly tool allows the operator to clamp and release the filter element using the handle and switch at the near end of the operating rod. This effectively prevents the operator from inhaling volatile aviation fuel vapors when probing into the oil filter separator, reducing the risk of inhaling harmful gases and ensuring the health and safety of the operators.
[0016] 3. In the process of using the oil filter separator filter element disassembly and assembly tool of this utility model, the operator can control the clamping force of the two clamping blocks on the filter element by pressing the switch on the handle, thereby ensuring stable contact between the clamping blocks and the filter element, ensuring the stability of the clamping of the filter element by the two clamping blocks, preventing the filter element from slipping and causing damage during disassembly and assembly, reducing the probability of damage to the filter element during disassembly and assembly, and making it reliable in use.
[0017] 4. The tool for disassembling and assembling an oil filter separator element of this utility model allows the operator to simultaneously adjust the installation position of the filter element by rotating their hand. This ensures that the filter element is precisely aligned with the clamp at the bottom of the oil filter separator, thereby simplifying the installation process, improving the convenience of filter element installation, reducing the time spent on repeatedly adjusting the filter element, and significantly improving installation efficiency.

[0032] Example 1:
[0033] This utility model proposes a tool for disassembling and assembling filter elements of an oil filter separator.
[0034] In one embodiment of this utility model, a tool for disassembling and assembling an oil filter separator element includes a rod 1, a handle 2, a connector 3, and a clamping assembly 4. The clamping assembly 4 includes two clamping blocks 5, which are movably mounted on one end of the rod 1. The handle 2 is located at the other end of the rod 1, and a switch 6 is provided on the handle 2. The connector 3 is connected to the switch 6 and the two clamping blocks 5 respectively, so that the two clamping blocks 5 can be moved closer or further apart by the switch 6 and the connector 3.
[0035] Working principle: In the process of using the oil filter separator filter element disassembly and assembly tool of this utility model, the operator grasps the handle 2 on the rod body 1 and presses the switch 6 on the handle 2, so that the two clamping blocks 5 move closer or further apart under the action of the connecting piece 3, thereby clamping or releasing the filter element, which facilitates the disassembly and assembly of the oil filter separator filter element. It is convenient and reliable to use.
[0036] Specifically, such as Figures 1 to 4 As shown, in this utility model of a tool for disassembling and assembling an oil filter separator element, the two ends of the rod 1 are respectively provided with handles 2 and two movably mounted clamping blocks 5. The switch 6 on the handle 2 is connected to the two clamping blocks 5 via a connector 3. This allows the operator to disassemble and assemble the filter element by gripping the handles 2 and operating the switch 6. That is, the rod 1 adapts to the installation depth of the filter element, and the two clamping blocks 5 at the far end of the rod 1 hold or release the filter element to complete the disassembly and assembly operation. This eliminates the need for the operator to probe into the oil filter separator, significantly extending the reach of the rod 1. The operating range overcomes the limitations of insufficient arm length for workers to disassemble and assemble filter elements, making it particularly suitable for disassembling and assembling the lower filter element in an oil filter separator. Furthermore, this utility model's tool for disassembling and assembling oil filter separator elements allows workers to clamp and release the filter element using the handle 2 and switch 6 at the near end of the operating lever 1, effectively preventing workers from inhaling volatile aviation fuel vapors when probing into the oil filter separator, reducing the risk of inhaling harmful gases, and ensuring the health and safety of operators.
[0037] Furthermore, in the use of this utility model's tool for disassembling and assembling oil filter elements, the operator can control the clamping force of the two clamping blocks 5 on the filter element by pressing the switch 6 on the handle 2. This ensures stable contact between the clamping blocks 5 and the filter element, guaranteeing the secure clamping of the filter element. The friction coefficient can be further increased by designing embossing, stripes, or raised dots (such as fish scale patterns or diamond patterns) on the surface of the clamping blocks 5, thereby significantly improving the clamping stability of the filter element and preventing slippage and damage during disassembly and assembly. This reduces the probability of filter element damage during disassembly and assembly, ensuring reliable use. Understandably, when the filter element needs to be installed, the operator can simultaneously adjust the installation position of the filter element by rotating their hand, allowing the filter element to be precisely aligned with the clamps at the bottom of the oil filter separator. This not only simplifies the installation process and improves the convenience of filter element installation, but also reduces the time spent repeatedly adjusting the filter element, significantly improving installation efficiency.
[0038] It is worth noting that, such as Figure 5 and Figure 6 As shown, in the manufacturing process of the oil filter separator filter element disassembly and assembly tool of this utility model, the rod body 1 can be made into a bent rod, thereby forming an eccentric structure to avoid the fixed tie rod used to install the filter element in the oil filter separator, avoiding the interference between the rod body 1 and the fixed tie rod, which would cause difficulties in disassembling and assembling the filter element, and improving the convenience and reliability of use.
[0039] In one embodiment, the rod 1 is hollow, the connector 3 passes through the rod 1, and the clamping assembly 4 also includes a sleeve 7. One end of the sleeve 7 is detachably connected to the rod 1, and the other end of the sleeve 7 is an open end 8 that gradually widens from top to bottom. Two clamping blocks 5 are movably installed on the open end 8 via the connector 3. Specifically, as shown... Figures 1 to 4As shown, in this utility model of a tool for disassembling and assembling an oil filter separator element, the rod body 1 is hollow, allowing the connector 3 to pass through the rod body 1 and connect with the switch 6 of the handle 2 and the two clamping blocks 5. This effectively prevents the connector 3 from being exposed and affecting the operator's operation, and eliminates the risk of the connector 3 getting caught or tangled in a narrow working space, facilitating operation. Furthermore, the sleeve 7 can be detachably connected to the rod body 1 by a threaded connection, which facilitates the disassembly, assembly, and replacement of the sleeve 7, and is beneficial for maintenance. At this time, because the open end 8 of the sleeve 7 is gradually widened from top to bottom, and the two clamping blocks 5 are movably installed in the open end 8 through the connector 3, when the operator presses the switch 6 on the handle 2, the two clamping blocks 5 move into the open end 8 under the action of the connector 3, so that the two clamping blocks 5 can simultaneously abut against the two side walls of the filter element, thereby realizing the clamping operation of the filter element. Moreover, the guiding characteristics of the gradually widened open end 8 effectively reduce the difficulty of aligning the filter element, ensure that the two clamping blocks 5 can contact the filter element synchronously to complete the clamping, and improve the clamping accuracy.
[0040] In one embodiment, specifically, as Figure 1 , Figure 2 and Figure 4 As shown, the side walls of the two clamping blocks 5 are respectively formed with ramps 9 that are adapted to the open end 8. That is, the inclination angle of the ramps 9 is consistent with the taper of the open end 8, so that the two clamping blocks 5 always move smoothly along the predetermined trajectory during the clamping and releasing of the filter element. The structural design is simple and reasonable. At the same time, the automatic centering effect generated by the inclined surface cooperation ensures that the two clamping blocks 5 can automatically adjust to a symmetrical state to clamp the filter element when they approach each other, so that the clamping force is evenly distributed on the side wall of the filter element, thereby ensuring the clamping stability and reliability of the filter element.
[0041] In one embodiment, a plurality of limiting grooves 10 are formed on the outer wall of the open end 8. Each of the limiting grooves 10 corresponds to one of the two clamping blocks 5. The extending direction of the limiting grooves 10 is consistent with the inclination direction of the ramp 9 on the two clamping blocks 5, and each of the two clamping blocks 5 is provided with a positioning post 11 that passes through the limiting groove 10. Specifically, as shown... Figures 2 to 4 As shown, the insertion and engagement of the positioning post 11 and the limiting groove 10 ensures that the clamping block 5 always moves along the inclined direction of the slope 9, thereby effectively preventing the clamping block 5 from moving freely inside the sleeve 7, improving the stability of the movement of the clamping block 5 relative to the sleeve 7, ensuring the clamping stability of the clamping block 5 on the filter element, and making it reliable in use.
[0042] In one embodiment, grooves 12 are respectively provided on opposite sides of the two clamping blocks 5, the two grooves 12 forming a clamping space for the filter element to extend into, and anti-slip pads 13 are provided at the bottom of both grooves 12. Specifically, as shown in the figure Figures 2 to 4As shown, since the two clamping blocks 5 can move closer or further apart under the action of the connecting piece 3, the clamping space can be increased or decreased, thereby enabling this utility model to clamp filter elements of different specifications and sizes, improving applicability and flexibility, and expanding the scope of application. Furthermore, through the contact between the anti-slip pad 13 and the filter element, the anti-slip pad 13 can be made of rubber material (such as fluororubber) with excellent aviation fuel resistance, anti-swelling properties, and a high coefficient of friction. This not only allows the elastic properties of the rubber material itself to adapt to slight deformation of the filter element surface, improving the clamping stability of the filter element, but also prevents excessive clamping force from damaging the filter element. Moreover, by setting embossing, stripes, or raised dots on the anti-slip pad 13, the coefficient of friction can be further increased, thereby effectively improving the clamping effect of the filter element and preventing slippage.
[0043] In one embodiment, the connector 3 is a pull rope, one end of the sleeve 7 is sleeved on the rod 1, and a locking hole is provided on the outer wall of the sleeve 7. A fastener 14 that abuts against the rod 1 is provided in the locking hole. Specifically, as shown... Figures 1 to 3 As shown, in this utility model of an oil filter separator filter element disassembly and assembly tool, a pull rope is used as the connecting piece 3 and is inserted into the hollow rod body 1. This reduces the requirements for the installation accuracy of the connecting piece 3 while ensuring the efficiency of force transmission. Furthermore, the fastener 14 can be a screw, that is, the fastener 14 is threaded into the lock hole, so that the operator can quickly adjust the installation position of the sleeve 7 on the rod body 1 by tightening the fastener 14 (the end of the fastener 14 is in close contact with the surface of the rod body 1 to achieve the fixed limit of the sleeve 7), thereby ensuring that the connecting piece 3 can always tighten the clamping block 5 to ensure the clamping effect of the filter element, and the use is reliable.
[0044] In one embodiment, a plurality of support rods 15 are formed evenly and at intervals along the circumference of the end of the rod 1 away from the handle 2, and a clamping assembly 4 is provided on each of the support rods 15. Specifically, as shown in the figure Figures 1 to 3 As shown, the filter element can be clamped at multiple points through several clamping components 4, thereby significantly improving the clamping effect of the filter element disassembly and assembly tool of the oil filter separator of this utility model and effectively reducing the probability of the filter element loosening.
[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
