[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] As mining dump trucks become larger, their fuel tanks also increase in size and height, making traditional refueling methods inconvenient and slow. Currently, a bottom-mounted quick-fill method is used, but the quick-fill port suffers from severe oil contamination, leading to blockages and a high failure rate. The dusty conditions in mining areas, combined with the high levels of oil and fumes at the quick-fill port, cause dust to accumulate, further clogging the port and damaging parts. Furthermore, the exposed quick-fill port is easily damaged during operation, rendering it unusable.

[0023] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a protective device for a quick fuel filler port on a mine car. Figure 1 As shown, it includes a hinge base 1, a hinge shaft 2, a mounting plate 3, a protective cover 4, a protective frame 5, a mounting post 6, an adsorption magnet 7, and a sealing sleeve 8; the hinge base 1 has mounting plates 3 at both ends and a hinge shaft 2 in the middle; the lower end of the mounting plate 3 is provided with a protective cover 4, one side of the protective cover 4 is provided with a mounting frame, the lower end of the mounting frame is provided with a mounting post 6, and an adsorption magnet 7 is installed on the mounting post 6.

[0024] The protective cover 4 and the protective frame 5 work together to cover the quick filling device 9, thereby preventing dust from entering the filling port of the quick filling device 9 and preventing blockage. Furthermore, the protective cover 4 can be rotated through the cooperation of the hinge seat 1, the hinge shaft 2 and the mounting plate 3, which makes it easy to open the protective cover 4 during filling and close the protective cover 4 when filling is completed. It also works with the protective frame 5 to prevent the filling port from being bumped. It is suitable for the working environment of mining dump trucks.

[0025] The hinge shaft 2 passes through the hinge base 1 and the mounting plate 3. The hinge base 1 and the hinge shaft 2 are movably connected, and the hinge shaft 2 and the mounting plate 3 are movably connected.

[0026] Specifically, when the protective cover 4 is opened or closed, the hinge shaft 2 rotates on the hinge frame, thereby opening and closing the protective cover 4. When refilling is required, the hinge shaft 2 rotates clockwise, and the protective cover 4 opens for refilling. After refilling is completed, the hinge shaft 2 rotates counterclockwise, and the protective cover 4 closes. To facilitate rotation, a bearing can be installed on the hinge frame and fitted onto the hinge shaft 2.

[0027] Mounting plate 3 and protective cover 4 are fixedly connected. The upper end of protective cover 4 is a circular plate 41, and the lower end of protective cover 4 is a square plate 42. The square plate 42 and the circular plate 41 are an integral structure. The circular plate 41 is located on one side of the protective frame 5, and the square plate 42 is located on one side of the mounting column 6.

[0028] Specifically, two mounting plates 3 are provided. The upper end of the mounting plate 3 is connected to the hinge shaft 2, and the lower end of the mounting plate 3 is fixedly connected to the protective cover 4. The protective cover 4 is installed in the required position through the mounting plate 3.

[0029] Specifically, the circular plate 41 of the protective cover 4 is used to cooperate with the protective frame 5 to prevent dust from entering the rapid filling device 9, and the square plate 42 of the protective plate is used to cooperate with the adsorption magnet 7 to adsorb the protective plate at the mounting column 6 position, so that the rapid filling device 9 is sealed.

[0030] The protective frame 5 is a circular frame, and a sealing sleeve 8 is installed on the protective frame 5. The sealing sleeve 8 is detachably connected to the protective frame 5 and is located between the protective frame 5 and the protective cover 4. The sealing sleeve 8 increases the sealing between the protective cover 4 and the protective frame 5, further preventing dust from entering the filling port and preventing blockage.

[0031] Specifically, the sealing sleeve 8 has good elasticity, can withstand compression and stretching to a certain extent, and can return to its original shape after deformation. It has excellent sealing performance, which can effectively prevent leakage of liquids and gases, and can also absorb vibration and impact, reducing noise transmission.

[0032] like Figure 2 As shown, the mounting post 6 is a cylindrical structure with a mounting groove 61 on it. An adsorption magnet 7 is installed inside the mounting groove 61. The side of the adsorption magnet 7 is in close contact with the inner wall of the mounting groove 61. The adsorption magnet 7 and the mounting post 6 are detachably connected.

[0033] Specifically, when the protective cover 4 is closed, it is held in place by the magnetic magnet 7, thus preventing the protective cover 4 from opening during bumps and allowing dust to enter, providing better protection and making it easier to open the protective cover 4.

[0034] Specifically, to ensure the protective cover 4 can be attracted, it can be made of iron or some magnetic alloy materials. The articulated frame, protective frame 5, and one end of the mounting post 6 are all fixedly connected to the mine car body. A handle is also provided on the protective cover 4 for easy opening during filling.

[0035] How to use the quick fuel filling port protection device for mining trucks: When refueling is required, pull the protective cover 4 to separate the square plate 42 part of the protective cover 4 from the adsorption magnet 7, and then refuel; after refueling, release the protective cover 4, so that the square plate 42 part of the protective cover 4 is attracted to the adsorption magnet 7, thereby allowing the protective cover 4 and the protective frame 5 to cooperate to seal the quick refueling device 9, effectively preventing the filling port from being blocked, and thus preventing damage to internal parts; the protective cover 4 and the protective frame 5 prevent splashed sand and gravel from colliding with the quick refueling device 9, thereby effectively preventing the filling port from being bumped, suitable for the working environment of mining dump trucks.

[0036] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
