Description

Technical Field

[0001] The utility model relates to the technical field of mining trucks, in particular to a mining truck with a multi-section vehicle body. Background Art

[0002] In mining operations and large-scale engineering projects, mining trucks are critical transportation equipment, carrying the heavy responsibility of transporting ore, waste rock, or construction materials from the mining site to processing or storage locations. Traditional mining trucks typically utilize a unibody design with a fixed body. This design offers good stability and load-carrying capacity, but its flexibility and adaptability are limited when navigating the complex and changing mining terrain and operating environment. Specifically, when navigating rugged mining roads, unibody mining trucks can struggle to maintain stability due to their excessively long body and high center of gravity, increasing the risk of rollover or overturning. To address these issues and improve the efficiency and safety of mining trucks in complex mining environments, multi-section mining truck designs are gradually emerging on the market. These shorter bodies offer greater stability during operation. Currently, mining truck bodies are primarily connected by ropes and chains. These ropes and chains are prone to wear and breakage after prolonged exposure to heavy loads and frequent vibration, making them prone to accidents. Therefore, developing and designing safer mining trucks is of great significance. Utility Model Content

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] A mining truck with a multi-section body includes a swing frame 1 and a front body 2; the swing frame 1 is a square plate with a circular hole in the middle of the square plate for connecting to the front body 2; a limit assembly 11 is provided at the lower part of the side of the square plate facing the front body 2, and two hinge plates 12 for connecting to the rear body are respectively provided at the upper and lower parts of the other side of the square plate, and a safety lifting ear 3 is provided at the top of the square plate; a safety lifting ear 3 is provided at the top of the compartment wall of the front body 2 facing the swing frame 1, and a pin shaft 4 can pass through the safety lifting ears 3 on the swing frame 1 and the front body 2 in sequence; a circular protrusion for connecting to the swing frame 1 is provided on the outer wall of the compartment of the front body 2 facing the swing frame 1; a bearing is provided between the swing frame 1 and the front body 2, the inner ring of the bearing is connected to the circular protrusion, and the outer ring of the bearing is connected to the circular hole; a baffle 21 is provided at the lower part of the outer wall of the compartment, and the baffle 21 is located below the limit assembly 11.
