Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, specifically relating to a side protection device for off-highway dump trucks. Background Technology

[0002] Off-highway dump trucks often experience minor collisions while operating in mines, necessitating the installation of side protection devices to safeguard the fuel tank. Currently, some off-highway dump trucks only use two outriggers with protective grilles for protection, which often presents the following problems during use: 1) The outrigger lever arms are long, and prolonged vibration can easily cause the outrigger base plates to crack; 2) In the event of a collision, the outriggers are prone to breakage at the bends, severely affecting the proper protection of the fuel tank. Therefore, it is necessary to propose improvements and optimizations to address these issues. Utility Model Content

[0003] The technical problem solved by this utility model is to provide a side protection device for off-highway dump trucks. By optimizing the protection structure of the fuel tank, a protective cover is formed by connecting the inner ends of the interconnected bracket assembly and the protective grille assembly to the rear end of the vehicle body to protect the fuel tank. Under the premise that the vehicle body structure itself protects the two ends of the fuel tank, all-round protection of the fuel tank from top to bottom and front to back is achieved. The resulting frame structure has good strength and stability, improves the protection effect of the fuel tank, has good vibration resistance and deformation prevention effect, and increases the service life of the protective structure.

[0004] The technical solution adopted by this utility model is: a side protection device for off-highway dump trucks, including a bracket assembly distributed on the inner side below the fuel tank and a protective grille assembly distributed on the outer side above the fuel tank. The inner sides of the bracket assembly and the protective grille assembly are fixedly connected to the rear end of the vehicle body, and the outer end of the bracket assembly is fixedly connected to the lower end of the protective grille assembly, so as to protect the fuel tank by covering it in the protective cover formed by the bracket assembly and the protective grille assembly.

[0005] The bracket assembly includes multiple L-shaped support rods with vertical sections located inside the fuel tank and horizontal sections located below the fuel tank, evenly distributed along the length of the protective grille assembly. The upper ends of the vertical sections of the L-shaped support rods are fixedly connected to the rear end of the vehicle body, and the ends of the horizontal sections of the L-shaped support rods are detachably and fixedly connected to the lower inner wall of the protective grille assembly via a connecting seat plate.

[0006] Furthermore, the connecting seat plate has a groove-shaped structure, and the two side plates of the connecting seat plate are respectively located on both sides of the horizontal section end of the L-shaped support rod, and are detachably fixed to the L-shaped support rod by bolts. The non-open end of the connecting seat plate is detachably fixed to the inner wall of the lower end of the protective grille assembly by bolts.

[0007] Furthermore, a reinforcing plate is fixed on the outer wall of the upper end of the vertical section of the L-shaped support rod, and the upper end of the vertical section of the L-shaped support rod, the reinforcing plate, and the rear end of the vehicle body are fixed together by bolts.

[0008] Furthermore, the protective grille assembly includes two horizontal L-shaped support legs located above the fuel tank and a vertical section located outside the fuel tank, and multiple grille plates horizontally fixed to the outside of the L-shaped support legs from top to bottom. The connecting plate fixed to the end of the horizontal section of the L-shaped support leg is fixedly connected to the rear end of the vehicle body by bolts, and the outer end of the bracket assembly is fixedly connected to the inner wall of the lowest grille plate.

[0009] Furthermore, the connecting plate has multiple reinforcing ribs evenly distributed on its surface, which are located around the outer periphery of the L-shaped leg and fixedly connected to the outer wall of the L-shaped leg.

[0010] Furthermore, a reinforcing inclined plate is provided at the corner position of the upper end of the L-shaped support leg, and the vertical section of the L-shaped support leg is fixedly connected to the corresponding grid plate by multiple bolts.

[0011] Advantages of this utility model compared to the prior art:

[0012] 1. This technical solution optimizes the protective structure of the fuel tank by using a protective cover formed by the interconnected bracket assembly and the inner end of the protective grille assembly fixedly connected to the rear end of the vehicle body to protect the fuel tank. Under the premise that the vehicle body structure itself protects the two ends of the fuel tank, it achieves all-round protection of the fuel tank from top to bottom and front to back, which solves the drawbacks of traditional protective structures such as vibration-induced weld failure and easy deformation due to low structural strength.

[0013] 2. This technical solution increases the strength of the protective structure by adding fixing points to the inner wall of the bottommost grid plate for connection with the support assembly, while also helping to disperse the effects of gravity and vibration, thus improving its service life.

[0014] 3. The protective shield structure formed by connecting the bracket assembly and the protective grille assembly in this technical solution will distribute the force received during a collision to the horizontal section of the L-shaped support rod and L-shaped support leg, which helps to reduce collision deformation and better protect the fuel tank.

[0015] 4. This technical solution has a simple structure, novel design, and low cost. The resulting frame structure has good strength and stability, which improves the protection effect on the fuel tank, has good vibration resistance and deformation prevention effect, and extends the service life of the protective structure.

Specifically, the connecting seat plate 1-2 has a groove-shaped structure, and the two side plates of the connecting seat plate 1-2 are located on both sides of the end of the horizontal section of the L-shaped support rod 1-1, and are detachably fixed to the L-shaped support rod 1-1 via bolts. The non-open end of the connecting seat plate 1-2 is detachably fixed to the lower inner wall of the protective grille assembly 2 via bolts. Specifically, a reinforcing plate 1-3 is fixed on the outer wall of the upper end of the vertical section of the L-shaped support rod 1-1, and the upper end of the vertical section of the L-shaped support rod 1-1, the reinforcing plate 1-3, and the rear end of the vehicle body are fixed together via bolts.

[0022] The specific structure of the protective grille assembly 2 is as follows: The protective grille assembly 2 includes two horizontal L-shaped support legs 2-1 located above the fuel tank and a vertical section located outside the fuel tank, and multiple grille plates 2-2 horizontally fixed to the outside of the L-shaped support legs 2-1 from top to bottom. The connecting plate 2-3 fixed to the end of the horizontal section of the L-shaped support leg 2-1 is fixedly connected to the rear end of the vehicle body by bolts. The outer end of the bracket assembly 1 is fixedly connected to the inner wall of the lowest grille plate 2-2. Specifically, multiple distribution plates are evenly distributed on the surface of the connecting plate 2-3. A reinforcing rib plate 2-4 is fixedly connected to the outer periphery of the L-shaped support leg 2-1 and to the outer wall of the L-shaped support leg 2-1; specifically, a reinforcing inclined plate 2-5 is provided at the corner position at the upper end of the L-shaped support leg 2-1, and the vertical section of the L-shaped support leg 2-1 is fixedly connected to the corresponding grid plate 2-2 by multiple bolts; in the above structure, by adding a fixing point connected to the bracket assembly 1 on the inner wall of the bottom grid plate 2-2, the strength of the protective structure is improved, while also helping to disperse the gravity and vibration effects it receives, thereby improving its service life;

[0023] This technical solution features a simple structure, novel design, and low cost. The resulting frame structure exhibits good strength and stability, enhancing the protection of the fuel tank, providing excellent vibration and deformation resistance, extending the service life of the protective structure, and further reducing maintenance costs.
