DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, a front protection component includes: a base plate 20, the base plate 20 is a plate with a cross-section of an I-shaped cross section, and the top four corners of the base plate 20 are fixedly connected with connecting rods 21, and the wall surface of the connecting rod 21 is provided with a fixing groove 22, and the fixing groove 22 is internally threaded with a stud 24. This is an existing technology and will not be described in detail here.

[0031] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the protective structure is arranged on the front wall surface of the base plate 20 to prevent the impact of stones. The protective structure includes: a front plate 30, a leakage groove 31, an alignment groove 32 and an alignment plate 28. The front plate 30 is movably connected to the front wall surface of the base plate 20, the leakage groove 31 is opened on the wall surface of the front plate 30, and the alignment groove 32 is symmetrically opened on the two side walls of the front plate 30. The alignment plate 28 is fixedly connected to the front wall surface of the connecting rod 21 located in front of the base plate 20, and the alignment plate 28 can be snapped into the alignment groove 32.

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the front plate 30 is composed of an arc-shaped plate and rectangular plates on both sides of the arc-shaped plate, the leakage groove 31 is a rectangular groove, and a plurality of leakage grooves 31 are evenly arranged on the arc surface of the front plate 30. The spacing between the symmetrical rectangular plates of the front plate 30 can be consistent with the spacing between the positions of the symmetrical connecting rods 21. The alignment grooves 32 are arranged on the side walls of the rectangular plates on both sides of the front plate 30. The alignment grooves 32 are in the shape of inverted right triangles. The alignment plates 28 are in the shape of inverted right triangles. The alignment grooves 32 on each side can adapt to the corresponding alignment plates 28 sizes. The protective structure also includes a connecting block 26, a lock groove 27, a solid block 33, a bolt 34 and a lock column 35. The connecting block 26 is in The top of each connecting rod 21 located symmetrically in front of the base plate 20 is fixedly connected respectively, and a locking groove 27 is opened on the front wall surface of each connecting block 26. The solid block 33 is fixedly connected to the top of the two rectangular plates of the front plate 30 respectively, and the bolt 34 is threadedly connected to the front wall surface of the solid block 33. The lock column 35 is rotatably connected to the rear wall surface of each solid block 33. The locking groove 27 consists of a rectangular groove in the upper part and a cylindrical groove in the lower part. The lock column 35 consists of a cylinder and a rectangular rod at the rear end of the cylinder. The locking groove 27 can adapt to the insertion of the lock column 35. The connecting block 26 has a threaded groove above the lock groove 27 that adapts to the bolt 34.

[0033] When in use, the device is installed to the bottom of the vehicle through the fixed column 25 provided on the wall of each connecting rod 21. When the front plate 30 meets the stone in front, the stone will first contact the curved surface of the front plate 30, and then the smooth wall of the front plate 30 will guide the stone to the side of the front plate 30 so as to miss the stone. When the front plate 30 needs to be disassembled and replaced, the symmetrical bolts 34 are unscrewed from the threaded holes of the connecting block 26, and then the locking column 35 is rotated upward. The locking column 35 can be rotated to the bottom rectangular block and the rectangular groove of the lock groove 27. The front plate 30 can be removed from the wall of the connecting rod 21, and the leakage groove 31 can be separated from the alignment groove 32 at the same time. When installing the front plate 30, the lock column 35 is rotated upward to fit the size of the lock groove 27, and then the alignment groove 32 and the leakage groove 31 are aligned. The solid block 33 and the front wall of the connecting block 26 are directly aligned, and then the bolt 34 is screwed into the corresponding wall of the connecting block 26. After the lock column 35 passes through the lock groove 27, it will automatically rotate downward due to the gravity of the rectangular block of the lock column 35. At this time, the lock column 35 and the lock groove 27 are staggered and locked;

[0034] In summary, by setting up a protective structure, the colliding stones can be effectively guided. The protective structure can make the stones displaced to the side along the curved surface of the front plate 30 by the way that the curved surface of the front plate 30 and the stones first contact each other, thereby avoiding the problem that the stones hit the front plate 30 and deform and then get stuck in the wall of the front plate 30. When the front plate 30 needs to be replaced, it is only necessary to remove the front plate 30 and replace it with a new one. Therefore, compared with the existing technology, the stone protection effect of this solution is better, and the cost of replacing the front plate 30 is lower.

[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, a plurality of identical fixing grooves 22 are formed in a linear array on the wall of the connecting rod 21. A plurality of connecting grooves 23 are also uniformly formed on the wall of the connecting rod 21. A fixing column 25 is fixedly connected to the end of the stud 24. The fixing column 25 is cylindrical, and the connecting groove 23 is circular. The diameter of the connecting groove 23 is smaller than that of the fixing groove 22. Each connecting groove 23 is located between each adjacent fixing groove 22. The connecting groove 23 can communicate with the adjacent fixing grooves 22 and can adapt to the diameter of the fixing column 25.

[0036] In actual use, when it is necessary to adjust the top of the bottom plate 20 to fit the bottom of the vehicle, the stud 24 is displaced from the fixing groove 22 by rotating. At this time, the fixing column 25 is located in the fixing groove 22. Then the entire device is moved downward or upward to fit the bottom of the vehicle, and finally the stud 24 is screwed back into the corresponding fixing groove 22 by rotating.

[0037] In summary, by providing a base plate 20 that can be flexibly adjusted on the bottom of the vehicle, there is no need to create specific models to adapt to vehicles with different bottom heights, so this solution can adapt to vehicles with different bottom heights.

[0038] A wide-body dump truck for mining, not shown in the figure, comprising a vehicle body and all of the above-mentioned front protection components;

[0039] By setting up the front protection component, the bottom of the vehicle can be effectively prevented from being scratched by stones and affecting the vehicle's driving, thereby improving the safety of the vehicle while driving.

[0040] Working principle: The device is installed on the bottom of the vehicle through the fixed column 25 provided on the wall of each connecting rod 21. When the front plate 30 encounters a stone in front, the stone will first contact the curved surface of the front plate 30. Then, due to the smooth wall of the front plate 30, the stone will be guided to the side of the front plate 30 and thus missed.

[0041] When the front plate 30 needs to be disassembled and replaced, the symmetrical bolts 34 are unscrewed from the threaded holes of the connecting block 26, and then the locking column 35 is rotated upward. The locking column 35 can be rotated until the rectangular block at the bottom is aligned with the rectangular groove of the locking groove 27, and the front plate 30 can be removed from the wall of the connecting rod 21. The leakage groove 31 can be synchronously separated from the alignment groove 32. When installing the front plate 30, the locking column 35 is rotated upward to fit the size of the locking groove 27, and then the alignment groove 32 and the leakage groove 31 are aligned. The solid block 33 and the front wall of the connecting block 26 are directly aligned, and then the bolt 34 is screwed into the corresponding wall of the connecting block 26. After passing through the locking groove 27, the locking column 35 will automatically rotate downward due to the gravity of the rectangular block of the locking column 35. At this time, the locking column 35 will be staggered and locked with the locking groove 27.
