Detailed Implementation

[0019] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figure 1-4 As shown, this utility model provides a fully hydraulic bulldozer 100, including a bulldozer blade (not shown), a front frame 1 and a rear frame 2. The bulldozer blade is fixed on the rear frame 2, and the front frame 1 is welded to the rear frame 2.

[0021] In this embodiment, specifically, a first mounting hole 11 is provided on the front frame 1.

[0022] In this embodiment, specifically, the rear frame 2 includes a left frame 21, a right frame 22, and a transverse reinforcing rib 3 transversely arranged between the left frame 21 and the right frame 22. The front ends of the left frame 21 and the right frame 22 are connected to a rear upright frame 23. The left frame 21 has a second mounting hole 212, and the right frame 22 has a third mounting hole 222. The pin passes through the second mounting hole 212 and the third mounting hole 222 to fix the bulldozer blade to the rear frame 2. When it is necessary to install or remove the pin (not shown in the figure), the pin is removed from the first mounting hole 11.

[0023] In this embodiment, specifically, the transverse reinforcing rib 3 includes a balance beam 31 and a crossbeam 32. The crossbeam 32 is provided with an installation structure 321. The balance beam 31 is fixed to the front end of the rear frame 2, and the crossbeam 32 is fixed to the rear end of the rear frame 2. The balance beam 31 is I-shaped. The upper end of the front frame 1 abuts against the lower side of the balance beam 31. When the front frame 1 is subjected to torsional load, the strong bending and torsional cross section of the I-shaped balance beam 31 can provide effective support, prevent the front frame 1 from undergoing excessive deformation, and thus significantly improve the torsional resistance of the front frame 1.

[0024] In this embodiment, specifically, the left frame 21, right frame 22, rear upright frame 23, and crossbeam 32 form a fixed frame, within which the radiator 4 is fixed. The crossbeam 32 serves as both a reinforcing structure for the bulldozer 100, where the left frame 21, right frame 22, rear frame 23, and reinforcing plate 26 work together to significantly improve the overall structural strength and deformation resistance of the bulldozer 100, effectively resisting stress impacts under complex working conditions, and a fixing structure for the radiator 4. Through the mounting structure 321 set on the surface of the crossbeam, the radiator 4 can be installed quickly and accurately without the need for additional complex auxiliary supports, greatly simplifying the radiator installation process and balancing the stability of the bulldozer 100 with the ease of installation of the radiator 4.

[0025] The radiator 4 is fixed within a fixed frame formed by the left frame 21, right frame 22, rear upright frame 23, and crossbeam 32, forming a stable installation structure. During bulldozer operation, this effectively reduces the impact of vibration on the radiator 4, preventing it from becoming loose or displaced, ensuring that the radiator 4 is always in good working condition, guaranteeing the heat dissipation effect of the hydraulic system, and improving the working performance of the bulldozer 100.

[0026] In this embodiment, specifically, a first fixing hole 211 is provided on the left frame 21, and a second fixing hole 221 is provided on the right frame 22.

[0027] In this embodiment, specifically, the rear frame 2 also includes a floor frame 24 and a pivot mounting frame 25, which are laterally arranged between the left frame 21 and the right frame 22.

[0028] In this embodiment, specifically, reinforcing plates 26 are arranged on the inner sides of the left frame 21 and the right frame 22. The reinforcing plates 26 include reinforcing plate one 261, reinforcing plate two 262, and reinforcing plate three 263.

[0029] In this embodiment, specifically, the rear frame 2 is welded into an integral structure by the left frame 21, the right frame 22, the rear upright frame 23, the bottom plate frame 24, the pivot mounting frame 25, the balance beam frame 31, and the crossbeam 32.

[0030] In this embodiment, specifically, reinforcing plate 1 261 is provided on the upper end of the balance beam frame 31, reinforcing plate 2 262 is provided on the lower side of the crossbeam 32, and reinforcing plate 3 263 is provided vertically at both ends of the crossbeam 32.

[0031] The left frame 21 and right frame 22 of the rear frame 2 serve as the main longitudinal load-bearing structures, transmitting the force from the ground upwards. The balance beam 31 and crossbeam 32 in the transverse stiffeners 3 provide transverse connection and reinforcement, dispersing and transmitting longitudinal and transverse forces to ensure uniform stress distribution throughout the bulldozer 100. The reinforcing plates 26 further enhance the connection strength of key components, preventing stress concentration and structural damage, thereby ensuring the structural stability and load-bearing capacity of the frame under complex working conditions.

[0032] In this embodiment, specifically, the radiator 4 is fixed to the rear end of the rear frame 2. The radiator 4 includes a fan 41 and a heat dissipation module 42. The fan 41 is arranged facing the inside of the rear frame 2, and the heat dissipation module 42 is arranged facing the outside of the rear frame 2.

[0033] In this embodiment, specifically, the heat dissipation module 42 has a third fixing hole 421 on its side. Screws are used to fix the heat dissipation module 42 to the left frame 21 and the right frame 22 through the first fixing hole 211, the second fixing hole 221, and the third fixing hole 421. The mounting structure 321 on the surface of the crossbeam 32 provides a mounting reference for the radiator 4. The third fixing hole 421 on the side of the heat dissipation module 42 is connected to the first fixing hole 211 on the left frame 21 and the second fixing hole 221 on the right frame 22 by screws, forming a stable fixing structure. This fixing method is not only convenient to install, but also ensures that the radiator 4 is firmly fixed to the frame.

[0034] In this embodiment, specifically, the heat dissipation module 42 in the radiator 4 is arranged vertically.

[0035] The beneficial effects of this utility model of a fully hydraulic bulldozer are as follows: 1. The "I"-shaped balance beam frame 31 has excellent anti-torque performance and can more efficiently distribute and transfer the huge load from the front frame 11 to the left frame 21 and right frame 22, avoiding stress concentration and improving the rigidity and durability of the overall structure of the rear frame 2.

[0036] 2. The rear frame 2 adopts a structural design in which the left frame 21, right frame 22, rear upright frame 23, bottom plate frame 24, pivot mounting frame 25 and transverse reinforcing rib 3 are welded into one piece. In particular, the fixed frame formed by the crossbeam 32 and other components greatly improves the overall rigidity and deformation resistance of the frame.

[0037] 3. The crossbeam 32 serves the dual functions of reinforcing the frame and fixing the radiator. The fixing holes on the left frame 21 and the right frame 22, as well as the fixing holes on the side of the heat dissipation module 42, allow the radiator 4 to be installed using only screws. No additional complex auxiliary brackets are required, which greatly reduces the installation difficulty and assembly time, improves production efficiency, and also reduces manufacturing costs.
