Description

Technical Field

[0001] This utility model relates to the technical field of refueling auxiliary devices, and in particular to a portable refueling auxiliary device. Background Technology

[0002] Existing multi-functional refueling vehicles are mostly developed as special-purpose vehicles, with complex designs, high manufacturing and maintenance costs, and cumbersome operation procedures from deployment to withdrawal, requiring specialized training for relevant personnel. Furthermore, during accompanying support missions, refueling vehicles also face practical problems such as large target size, poor mobility, and limited adaptability, making them difficult to effectively deploy at the grassroots level.

[0003] Currently, a large number of old-style fuel tankers equipped at the grassroots level, taking the CA1253P7K2L7T1E model as an example, only have fuel storage functions and cannot directly refuel mission vehicles, making it difficult to meet the fuel needs of the troops for routine missions. In addition, directly retiring and replacing these fuel tankers would result in a huge waste of resources. Therefore, there is an urgent need to design an auxiliary device that can connect fuel tankers with mission vehicles for refueling. Utility Model Content

The small diameter end of the variable diameter conical part is fixedly connected to the assembly docking part as a whole. The assembly docking part is adapted to be installed in a docking groove provided on the valve cover, and the assembly docking part is limited and fixed by the connecting components provided on both sides of the valve cover.

[0007] The oil inlet connection and the valve cover are provided with through holes on both sides at the mounting connection assembly, and hinge seats are provided on both sides of the through holes of the oil inlet connection and the valve cover.

[0008] The connecting assembly consists of a clamp head, a pin, and an operating handle. The clamp head is an irregular circular structure with an eccentric hole. The pin passes through the eccentric hole of the clamp head and hinges the clamp head between two sets of hinge seats. The clamp head is located at the through hole and is connected to the operating handle.

[0009] Furthermore, limiting grooves are provided on both sides of the outer wall of the assembly docking part, and the position of each limiting groove corresponds to and matches the position of the clamp head.

[0010] Furthermore, the valve cover is provided with an oil outlet and a connecting end is provided at the oil outlet. The connecting end is used to connect with the oil pipeline to supply oil to the vehicle to be refueled.

[0011] Furthermore, the number of oil outlets is ≥1.

[0012] Furthermore, a first sealing ring is provided inside the oil inlet connection to enhance the sealing performance after the oil inlet connection is connected to the oil outlet of the tanker truck.

[0013] Furthermore, a second sealing ring is provided at the bottom of the mating groove of the valve cover to enhance the sealing performance after the assembled mating part is connected to the valve cover.

[0014] The beneficial effects of this utility model are:

[0015] This utility model provides a refueling auxiliary connection device that enables connection between old-style tank trucks that are currently unable to transport oil and vehicles that need refueling. The device achieves the required diameter change through the variable-diameter conical part on the valve body, and connects to the vehicle needing refueling through the connection ends at the multiple oil outlets on the valve cover and the oil pipeline, thereby solving the problem of old-style tank trucks being unable to supply oil.

[0027] Example 1

[0028] like Figure 3 As shown, the valve body 1 is composed of an oil inlet connection part 11, a variable diameter conical part 12 and an assembly docking part 13. The oil inlet connection part 11 is fixedly connected to the variable diameter conical part 12 and located at the large diameter end. The small diameter end of the variable diameter conical part 12 is fixedly connected to the assembly docking part 13 as a whole.

[0029] like Figure 1 and 5 The oil inlet connection 11 has connecting components on both sides, and the assembly docking part 13 is adapted to be installed in the docking groove provided on the valve cover 2. The assembly docking part 13 is limited and fixed by the connecting components provided on both sides of the valve cover 2. Specifically, through holes 21 are provided on both sides of the oil inlet connection 11 and the valve cover 2 at the locations where the connecting components are installed, and hinge seats 4 are respectively provided on both sides of the openings of the through holes 21 on the oil inlet connection 11 and the valve cover 2. The connecting components are installed between the two sets of hinge seats 4.

[0030] The connecting assembly consists of a clip 51, a pin 6, and an operating handle 52. The clip 51 is an irregular circular structure with an eccentric hole. The pin 6 passes through the eccentric hole of the clip 51 and hinges the clip 51 between two sets of hinge seats 4. The clip 51 is located at the through hole and is connected to the operating handle 52.

[0031] like Figure 5 and 6 Limiting grooves 131 are provided on both sides of the outer wall of the assembly docking part 13, and the position of each limiting groove 131 corresponds to and matches the position of the clamp head 51.

[0032] like Figure 4 The valve cover 2 is provided with an oil outlet 22 and a connecting end 3 is provided at the oil outlet 22. The connecting end 3 is used to connect to the oil pipeline and supply oil to the vehicle to be refueled. The number of oil outlets 22 is ≥1.

[0033] like Figure 5 A first sealing ring 7 is provided inside the oil inlet connection part 11 to enhance the sealing performance after the oil inlet connection part 11 is connected to the oil outlet of the tank truck. A second sealing ring 8 is provided at the bottom of the mating groove of the valve cover 2 to enhance the sealing performance after the assembled mating part 13 is connected to the valve cover 2.

[0034] Example 2

[0035] The specific operation for refueling using this utility model is as follows:

[0036] Safety setup: Install two sets of electrostatic grounding devices on the oil truck and the vehicle to be refueled respectively. During installation, fix one end of the cable to the rear bumper of the vehicle and connect the other end to the ground through ground spikes. The distance between the two ground spikes should be no less than 20m and should not affect the oil transfer operation.

[0037] In this utility model, the valve body is installed as follows: After closing the unloading valve on the oil truck, the oil inlet connection part 11 of this utility model is directly connected to the unloading port inside the oil tanker's unloading box. The connection components on both sides of the oil inlet connection part 11 are used for limiting and fixing. By rotating the operating handle 52 to a vertical state, the clamp 51 abuts against the unloading port of the unloading box to complete the connection operation. The first sealing ring 7 embedded inside the oil inlet connection part 11 achieves oil-gas sealing. The oil inlet connection part 11 is integrally connected to the variable diameter tapered part 12. The small diameter end of the variable diameter tapered part 12 is integrally set with the assembly docking part 12 to change the unloading port diameter of the oil tanker to adapt to valve covers 2 of different sizes. The variable diameter component is then installed.

[0038] In this utility model, the valve cover is installed as follows: after the oil inlet port of the valve cover 2 is connected to the oil outlet port of the assembly docking part 13, the valve cover 2 is fixed by the connecting components on both sides. The second sealing ring embedded inside the valve cover 2 is used to achieve oil-gas sealing. The oil outlet end 3 of the valve cover 2 is connected to the fuel dispenser hose, and the interface is reinforced with an interface clamp. The valve cover is then installed.

[0039] Installation of refueling accessories: Take 3 or 6 refueling hoses of 20m or 30m in length (select the length and quantity of the hose according to the actual working range and needs), connect one end to the oil outlet end 3 of valve cover 2, and connect the other end directly to the refueling gun with metering. All interfaces are reinforced with interface clamps. The refueling components are now assembled.

[0040] After completing the above steps, when refueling, you need to depress the clutch of the tanker truck, turn on the power take-off switch, and the vehicle body will start to supply power. Then, align the metered refueling nozzle with the fuel filler port of the transport vehicle (the vehicle to be refueled), and open the unloading valve on the tanker truck to complete the refueling operation.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
