Technical Field

[0001] This utility model belongs to the field of radiator core frame reinforcement technology, specifically relating to a reinforcement device for the outer frame of a large excavator radiator. Background Technology

[0002] The radiator core is a common cooling device on excavators, capable of quickly and effectively cooling the engine. Current technology uses an outer frame to protect the radiator core and the cooling fan at its rear. However, existing outer frames are large and heavy, making them prone to structural deformation under the severe vibrations and impacts of excavators. The outer frame may not be securely fixed, easily wobbling, and welds may crack or even break. Furthermore, due to the complex road conditions in which excavators operate, the radiator core is bolted to the outer frame; prolonged exposure to high-frequency vibrations can cause these bolts to loosen, thus affecting the radiator core's cooling effect on the engine.

The third frame 4 has a U-shaped cross-section and is fitted onto the upper end of the first frame 2. Multiple mounting holes of the same size and corresponding in position are provided on both the third frame 4 and the first frame 2. The first frame 2, the second frame 3, and the third frame 4 are connected by bolts passing through the corresponding mounting holes.

Finally, the second frame 3 is placed at the rear end of the first frame 2, aligning the mounting holes. The first frame 2 and the second frame 3 are then fixed with bolts.

[0038] The inclined fixed tube converts impact energy into axial stress, and multiple sets of triangular supports further reinforce the outer frame, integrating it into a whole to prevent the outer frame from shaking when the excavator is working; at the same time, the bolt connection facilitates quick disassembly and replacement, improving efficiency.
