[0001] The invention relates to the technical field of open-pit mine dump trucks, and in particular to an open-pit mine dump truck valve protection cover and a use method thereof. Background Art

[0002] In open-pit mining operations, dump trucks are commonly used as transportation tools to carry large amounts of ore and earth. These vehicles usually work in harsh environments, including rugged terrain and changing weather conditions. Under such working conditions, the tires of dump trucks need to be frequently inspected and maintained to ensure the normal operation of the vehicle and safe operation.

[0003] The tire valve is a key component for tire inflation and tire pressure monitoring. As open-pit dump trucks are equipped with upgraded tire pressure monitoring devices, it is necessary to install an external tire pressure sensor on the original valve. After the sensor is installed, the original valve is lengthened by 60mm, which makes it easy to scratch the valve when the car is driving. Since the valve is exposed to the outside, the valve is easily blocked by splashing mud on the ground when the tire is driving. In order to solve these problems, the existing technology chooses to install a protective cap on the valve or use more durable materials to manufacture the valve. However, these solutions often have limitations. For example, the protective cap may fall off under strong impact, or the cost of special materials is high and is not suitable for large-scale applications.

[0004] Therefore, it is necessary to develop a new type of valve protection cover that can effectively protect the valve mouth in harsh working environments, prevent scratches and mud clogging, and also take into account cost-effectiveness and ease of operation. The present invention is produced under the background of such technical requirements, and aims to provide a valve protection cover with simple structure, low cost and good protection effect, so as to improve the reliability and maintenance efficiency of dump trucks in open-pit mine operations.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1

[0029] Reference Figure 1 , which is the first embodiment of the present invention, provides a valve protection cover for an open-pit mine dump truck, the device includes a mounting unit 100, including a mounting plate 101, which is directly fixed on both sides of the tire valve. The design of the mounting plate 101 makes the protection cover fit closely with the tire, and is convenient for installation and removal of the protection cover. The mounting shell 102 arranged on the mounting plate 101 can support and protect the internal protection part 103, and the protection part 103 arranged on the mounting shell 102 is used to resist scratches and silt blockage, and is convenient for daily maintenance and inspection. The design of the mounting unit 100 ensures that the protection cover can be firmly installed on the tire and can remain stable even in harsh working environments. The design of the protection part 103 effectively prevents the valve from being scratched and blocked by silt, thereby extending the service life of the valve; and,

[0030] The self-locking unit 200 includes a door shaft 201 arranged on the mounting shell 102, which can ensure that the protection door 202 can rotate flexibly and remain stable when closed. The protection door 202 arranged on the door shaft 201 can effectively prevent silt and moisture from entering, and the self-locking part 203 arranged on the protection door 202 can prevent accidental opening during vehicle driving, thereby ensuring the reliability of the device. The design of the self-locking unit 200 makes the opening and closing of the protection door 202 simple and quick, which is convenient for daily maintenance and inspection by the staff.

[0031] Among them, two groups of mounting plates 101 are provided, and the mounting plates 101 are symmetrically arranged relative to the mounting shell 102. Each group of mounting plates 101 corresponds to the bolt positions on both sides of the tire, thereby ensuring that the protective cover can evenly withstand the force from both sides during installation, avoiding the displacement or damage of the protective cover caused by uneven installation.

[0032] During use, align the two sets of mounting plates 101 of the valve protection cover with the bolt positions on both sides of the tire valve respectively to ensure that the center of the protection cover is aligned with the valve stem, fix the mounting plates 101 to the tire with bolts, and use the wheel bolts to ensure that the protection cover is stable and immovable. During normal driving of the vehicle, the protection part 103 of the protection cover effectively prevents the valve stem from being scratched and blocked by mud, ensuring normal inflation of the tire and tire pressure monitoring. When it is necessary to inflate the tire or check the tire pressure, the operation can be performed by opening the protection door 202. After the protection door 202 is closed, it can ensure that the protection door 202 will not be accidentally opened during driving of the vehicle, thereby avoiding potential safety risks.

[0033] Example 2

[0034] Reference Figure 1 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the protection part 103 includes an anti-collision plate 103a arranged on the top of the mounting shell 102, and a vent 103b arranged on the anti-collision plate 103a. The anti-collision plate 103a is arranged on the top of the mounting shell 102, which can resist the impact or pressure from the top of the vehicle. It can be suitable for environments such as open-pit mines, where the vehicle may encounter falling stones or other falling objects from high altitude. The vent 103b is arranged on the anti-collision plate 103a to ensure that the pressure inside and outside the valve mouth is constant, avoid inaccurate tire pressure monitoring caused by poor air circulation, and prevent larger objects or silt from entering the protective cover.

[0035] Compared with Example 1, further, the self-locking part 203 includes a fixing plate 203a arranged on the protective door 202, and an opening pin 203b arranged on the mounting shell 102. The fixing plate 203a is arranged on the protective door 202 to provide stable support and fixation when the protective door 202 is closed, and the fixing plate 203a is precisely matched with the opening pin 203b on the mounting shell 102, so that the locking is more stable and reliable. When the protective door 202 is closed, the opening pin 203b is inserted into the fixing plate 203a to achieve self-locking, ensuring that the protective door 202 will not be accidentally opened due to vibration or external force during the driving of the vehicle, thereby protecting the valve nozzle from damage, and the staff can easily open and close the protective door 202 to perform maintenance and inspection of the valve nozzle, thereby extending the service life of the protective cover.

[0036] Compared with Example 1, further, a threaded hole 101a is provided on the mounting plate 101, which can directly cooperate with the bolts on the tire to fix the protective cover, facilitate installation by the staff, and can make the connection between the protective cover and the tire more stable, reducing the risk of loosening or falling off of the protective cover due to loose installation. At the same time, the design of the threaded hole 101a enables the protective cover to adapt to bolts of different models and specifications, thereby improving the versatility and adaptability of the product. When the protective cover needs to be maintained or replaced, the threaded hole 101a makes the disassembly process more convenient, and the staff can quickly remove the bolts and take down the protective cover for necessary inspection or replacement.

[0037] Compared with Example 1, further, the inner wall surface of the installation shell 102 is bonded with shock-absorbing cotton, which can further reduce the impact of external impact on the valve mouth and improve the overall protective performance of the protective cover. The shock-absorbing cotton can effectively absorb and disperse the impact force and protect the valve mouth from direct impact, especially in harsh environments such as open-pit mines, and can effectively protect the valve mouth from damage.

[0038] Compared with Example 1, further, the protection door 202 can freely rotate around the door axis 201180°, so that when the staff needs to inflate, inspect or maintain the valve mouth, they can easily open the protection door 202 without removing the entire protective cover, making the opening and closing of the protection door 202 more convenient and improving work efficiency. After use, the protection door 202 can be easily rotated back to its original position to continue to protect the valve mouth from external damage, and it is more intuitive for the staff to operate, effectively avoiding the staff from forgetting to continue locking the protection door 202 after opening it, thereby improving the stability of the device, and at the same time facilitating the staff to check and improve work efficiency.

[0039] The remaining structures are the same as those of Example 1.

[0040] Example 3

[0041] Reference Figure 1 , which is the third embodiment of the present invention, provides a method for using a valve protection cover of an open-pit mine dump truck, comprising:

[0042] When in use, the protective cover is installed on the bolts on both sides of the valve mouth through the threaded holes 101a on the mounting plate 101, so that the protective door 202 faces upward, which is convenient for the staff to check or repair the valve mouth;

[0043] At this time, the valve is located inside the mounting housing 102 and can be fully protected by the protective cover, and the top of the valve does not touch the inner wall of the anti-collision plate 103a, which effectively prevents the valve from rubbing or colliding with the inner wall of the anti-collision plate 103a due to vibration or impact during vehicle driving, thereby protecting the valve from damage and ensuring the safety of the valve in harsh environments and the convenience of maintenance.

[0044] Compared with Example 2, further, when it is necessary to inflate the tire or replace the sensor, the operation can be carried out by opening the cotter pin 203b. The cotter pin 203b is located on the mounting shell 102 and cooperates with the fixing plate 203a on the protective door 202 to maintain the stability and safety of the protective door 202 when it is in a closed state. After unlocking, the protective door 202 can be easily opened to expose the valve stem. The design of the protective door 202 allows it to rotate freely around the door axis 201180°, providing sufficient operating space and making the operation more convenient for the staff. After the operation is completed, close the protective door 202 and re-lock the cotter pin 203b to ensure that the protective cover remains in a closed state during the driving of the vehicle and continues to protect the valve stem.

[0045] Compared with Example 2, further, when the tire is running, the anti-collision plate 103a effectively prevents the splashing of ground mud onto the valve stem, and the staff can observe the status of the valve stem and the sensor at any time through the air vent 103b. The anti-collision plate 103a is located on the top of the mounting shell 102, which can block the splashing of ground mud and gravel during driving, and effectively protect the valve stem from pollution and damage, which is particularly important in muddy or dusty open-pit mining environments, ensuring the cleanliness and normal function of the valve stem. The air vent 103b is not only for air circulation, but also provides an observation window, so that the staff can check the status of the valve stem and the sensor at any time, which increases the practicality of the protective cover, while improving the efficiency and accuracy of monitoring, reducing the number of times the protective door 202 is opened, thereby reducing the complexity and time of maintenance.

[0046] The remaining structure is the same as that of Example 2.
