[0032] The adjustable upper protective device for a dump truck and the vehicle provided by the utility model are now described.

[0033] like Figures 1 to 3 As shown, the adjustable upper protection device of the dump truck provided by the first embodiment of the present invention includes a lower protection component 10, a middle protection component 20 and an upper protection component 30. The lower protection component 10 is used to be connected to the vehicle body; the middle protection component 20 is detachably connected to the upper part of the lower protection component 10; the upper protection component 30 is detachably connected to the upper part of the middle protection component 20; wherein, the lower protection component 10 and the upper protection component 30 can be detachably connected.

[0034] Compared with the prior art, the adjustable upper protective device for the dump truck provided in this embodiment is more convenient when in use. Since the lower protection assembly 10, the middle protection assembly 20 and the upper protection assembly 30 are detachably connected, the height of the top of the upper protection assembly 30 can be adjusted by choosing whether to install the middle protection assembly 20, thereby adjusting the overall height of the adjustable upper protective device of the dump truck to meet usage requirements.

[0035] like Figures 1 to 6 As shown, the present invention provides a specific implementation method based on the first implementation method as follows:

[0036] The upper part of the lower section protection assembly 10 and the upper part of the middle section protection assembly 20 are both provided with at least two sockets 41, and the two sockets 41 are arranged at intervals; the lower part of the middle section protection assembly 20 and the lower part of the upper section protection assembly 30 are both provided with plugs 42 that are plugged into and matched with the sockets 41; among them, the plug 42 at the lower part of the upper section protection assembly 30 can be plugged into and matched with the socket 41 at the upper part of the lower section protection assembly 10.

[0037] Through such a plug-in structure, the disassembly connection between the lower section protection component 10, the middle section protection component 20 and the upper section protection component 30 can be conveniently and reliably realized. By choosing whether to install the middle section protection component 20, the height of the top of the upper section protection component 30 can be adjusted, thereby adjusting the overall height of the adjustable upper protection device of the dump truck to meet the usage requirements.

[0038] A pin hole 43 is provided between the socket 41 and the plug 42 so as to connect and fix the socket 41 and the plug 42 via a pin, thereby improving the reliability of the connection.

[0039] There is a margin between the plug 42 and the socket 41 to achieve positioning by plugging; the upper part of the lower section protection component 10, the lower and upper parts of the middle section protection component 20, and the lower part of the upper section protection component 30 are all provided with corresponding bolt holes 44 to achieve a more precise and detachable connection by bolts.

[0040] During manufacturing, welding deformation and connection errors can easily lead to difficulties in achieving a precise and tight connection between the plug 42 and the socket 41. However, the bolt holes 44 can be drilled after the lower, middle, and upper guard assemblies 10, 20, and 30 are manufactured, resulting in greater precision. This allows for a margin between the plug 42 and the socket 41, allowing them to position and provide some support. The bolt holes 44, in conjunction with the bolts, allow for a precise and tight connection between the lower, middle, and upper guard assemblies 10, 20, and 30, preventing loosening or wobbling.

[0041] The upper part of the lower section protection component 10, the lower and upper parts of the middle section protection component 20, and the lower part of the upper section protection component 30 are all provided with a bending edge 45, and the bolt hole 44 is provided on the bending edge 45. The direct bending form is conducive to simplifying the production process, avoiding welding deformation, and ensuring the accuracy of the connection position; the bending edge 45 is provided with an avoidance groove at the position corresponding to the socket 41 or the plug 42 to ensure the plug-in fit of the socket 41 and the plug 42.

[0042] like Figure 4As shown, the upper protection assembly 30 includes an upper main board 31, an upper bending plate 32, an upper flap 33 and an L-shaped reinforcing side panel 35. The lower portion of the upper main board 31 is used for detachable connection with the upper portion of the lower protection assembly 10 or the upper portion of the middle protection assembly 20; the upper bending plate 32 is connected to the upper portion of the upper main board 31, and is set at an angle to the upper main board 31; the upper flap 33 is connected to the upper bending plate 32 for rotation and limiting; the L-shaped reinforcing side panels 35 are respectively connected to the sides of the upper main board 31 and the upper bending plate 32 for reinforcement.

[0043] When the upper flap 33 is turned up, it can be stacked on the upper part of the upper bending plate 32, and when the upper flap 33 is turned back, it can be flush with the upper bending plate 32. In this way, the occupancy of the cargo box space can be reduced by folding the upper flap 33, reducing the risk of upper protection being broken.

[0044] The upper main board 31 and the upper bending plate 32 are an integral structure formed by bending. Direct bending is conducive to simplifying the production process, avoiding welding deformation, and ensuring the accuracy of the connection position; the upper flap 33 and the upper bending plate 32 are rotatably connected through the hinge 34 to achieve the flipping and limiting of the upper flap 33.

[0045] like Figure 5 As shown, the middle section protection assembly 20 includes a middle section main board 21 and side wing panels 22. The middle section main board 21 is provided with a socket 41 on the upper part and a plug 42 on the lower part. The side wing panels 22 are provided on both sides of the middle section main board 21 and are provided at an angle to the middle section main board 21. The middle section main board 21 and the side wing panels 22 are an integral structure formed by bending. The direct bending form is conducive to simplifying the production process, avoiding welding deformation, and ensuring the accuracy of the connection position.

[0046] like Figure 6 As shown, the lower section protection assembly 10 includes a lower section main board 11, a mounting plate 12 and an L-shaped reinforcement rod 13. A socket 41 is provided on the upper part of the lower section main board 11. The mounting plate 12 is connected to the lower part of the lower section main board 11 and is set at an angle to the lower section main board 11. The L-shaped reinforcement rod 13 is respectively connected to the lower section main board 11 and the mounting plate 12 for reinforcement.

[0047] The lower section protection assembly 10, the middle section protection assembly 20 and the upper section protection assembly 30 are all provided with reinforcement tubes, and the ends of the reinforcement tubes form sockets 41 and plugs 42, so as to ensure the strength of the sockets 41 and the plugs 42 while also being able to strengthen the lower section protection assembly 10, the middle section protection assembly 20 and the upper section protection assembly 30.

[0048] The vehicle provided in the second embodiment of the present invention includes the above-mentioned adjustable upper protective device of the dump truck.

[0049] Compared with the prior art, the vehicle provided in this embodiment has the above-mentioned adjustable upper protective device for dump trucks. Since the lower protection assembly 10, the middle protection assembly 20 and the upper protection assembly 30 are detachably connected, the height of the top of the upper protection assembly 30 can be adjusted by choosing whether to install the middle protection assembly 20, thereby adjusting the overall height of the adjustable upper protective device of the dump truck to meet usage requirements.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
