Description

Technical Field

[0001] This utility model relates to the field of fuel filling technology, and more specifically, to a pipeline storage structure for a fuel filling system. Background Technology

[0002] With social development, the application scenarios of excavators have gradually broadened. In some places, it is difficult to use them or the cost of using professional refueling trucks is too high. Therefore, excavators with built-in fuel pumps have gradually gained favor with customers. How to better utilize the fuel pump has become a question that practitioners need to consider.

[0003] On typical fuel filler pumps mounted on a fixed frame, movable hoses are either placed directly in the toolbox or coiled up within the toolbox and pump chamber, hanging from two bent iron rods. This method is relatively simple to construct and operate. If the movable hoses are in the toolbox, the toolbox becomes cluttered with other tools, making tool management difficult. If the movable hoses are in the pump chamber, the numerous hoses there can easily crisscross, hindering their use. Furthermore, due to the harsh working environment of excavators, the lack of separate protective measures makes the hoses susceptible to contamination, which in turn affects the cleanliness of the fuel tank and engine fuel supply system. Utility Model Content

[0004] The purpose of this invention is to provide a pipeline storage structure for fuel filling systems, solving the problem of messy and disorganized moving pipelines in fuel filling pumps and making the internal pipelines harmonious and aesthetically pleasing. It also protects the pipelines from environmental contamination.

[0005] This utility model is achieved through the following technical solution:

[0006] A pipeline storage structure for a fuel filling system includes a housing mounted on a vehicle frame. The housing includes a bent plate connected to a bottom plate and a back plate, and a cover plate connected to the bent plate via hinges. A pipeline connector is provided on the bent plate, with one end connected to a movable pipeline and the other end connected to a filling pipeline. The pipeline connector connects the movable pipeline and the filling pipeline, achieving functional zoning and avoiding mutual interference between pipelines. A suction valve is connected to the movable pipeline and fixed by a hose clamp. A filling pump is connected to the filling pipeline and mounted on the vehicle frame. The filling pump is connected to a fuel tank.

[0007] Furthermore, the oil suction valve is provided with a protective sleeve on the outside, and the protective sleeve is connected to the back plate by a rope; the oil suction valve is provided with a rubber protective sleeve on the outside, which can effectively prevent external impact or vibration from damaging the oil suction valve and extend the service life of the equipment.

[0008] Furthermore, the protective sleeve is equipped with a buckle I, which secures one end of a rope, while the other end of the rope is connected to a buckle II, which is fixed to the back panel. By connecting the protective sleeve to the back panel with a rope and securing it with buckles I and II, the protective sleeve is ensured to remain in place during use, further enhancing safety.

[0009] Furthermore, the protective sleeve material is rubber; using rubber as the protective sleeve material provides good wear resistance and impact resistance, effectively buffering external pressure and protecting internal components.

[0010] Furthermore, the cover plate is provided with a cover plate lock, and the back plate is provided with a lock seat, which cooperates with the cover plate lock to limit the movement.

[0011] Furthermore, the base plate has pre-reserved welding nuts, which, together with anti-loosening sleeves and long bolts, fix the box to the frame. The lower end of the box is lifted by anti-loosening sleeves to prevent direct contact between the box and the frame, and to prevent the protrusion of the frame from affecting the installation of the box, thereby increasing the reliability of the box installation.

[0012] Furthermore, the bending plate is equipped with a control panel, which is connected to the filling pump via a cable. The control panel contains a control switch; pressing the switch on the control panel controls the opening and closing of the filling pump circuit. The control panel is fixed to the bending plate with screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model places the movable pipeline inside a sealed box, which protects the pipeline from contamination and avoids pipeline crossing, making the overall pipeline layout more aesthetically pleasing.

[0015] 2. This utility model has a rope fixed on the back plate, and the other end of the rope is connected to a protective sleeve, so that the pipe opening of the movable pipe faces upward, avoiding the exposure of residual oil in the pipe and contaminating the pipe, and allowing the user to find the fuel filling pump suction valve in time when using it.

[0016] 3. This utility model is equipped with a pipe joint, which connects the movable pipe inside the box with the filling pipe outside the box, separating the pipes of different parts, realizing functional zoning, and avoiding mutual interference between pipes.

[0017] 4. The lower end of the enclosure in this application is supported by an anti-loosening sleeve to prevent direct contact between the enclosure and the frame, thus preventing the frame protrusion from affecting the installation of the enclosure and increasing the reliability of the enclosure installation.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Example 1: A pipeline storage structure applied to a fuel filling system, such as... Figures 1-5As shown, the device includes a housing made of Q235 carbon steel, mounted on a vehicle frame. The housing includes a bent plate 6 connected to a bottom plate 13 and a back plate 7. The bent plate 6 is connected to a cover plate 1 via two hinges 2. A pipe connector 11 is provided on the bent plate 6, with one end connected to a movable pipe 10 and the other end connected to a refueling pipe 19. Connecting the movable pipe 10 and the refueling pipe 19 via the pipe connector 11 achieves functional zoning and avoids mutual interference between pipes. The movable pipe 10 is made of PVC plastic. The movable pipe 10 is connected to a suction valve 14, which is fixed inside the housing by a hose clamp 12. The refueling pipe 19 is connected to a refueling pump 18, which delivers fuel to the pump. The refueling pump 18 is mounted on the vehicle frame and connected to a fuel tank. The refueling pipe 19 is fixed to the inner edge of the vehicle frame by a pipe clamp 20. This utility model places the movable pipe 10 inside a sealed box, which protects the pipe from contamination and avoids pipe crossing, making the overall pipe layout more aesthetically pleasing.
