Description

Technical Field

[0001] This disclosure belongs to the field of mining truck equipment technology, specifically relating to a hybrid rigid mining truck water tank cover and a rigid mining truck. Background Technology

[0002] The statements herein provide only background information in relation to this disclosure and do not necessarily constitute prior art.

[0003] Rigid mining trucks are large engineering transport vehicles specifically designed for mining operations. They are primarily used for short-distance, heavy-load transportation in open-pit mines, undertaking the efficient transfer of materials such as ore and earth. Their core feature is a rigid frame structure (non-articulated body), providing extremely high load-bearing capacity, reliability, and adaptability to complex terrain, making them a critical transport equipment in mining operations.

[0004] The reliability of the power system and heat dissipation structure of rigid mining trucks directly determines the equipment's operating efficiency. With the increasing prevalence of hybrid technology (engine-generated power + battery-driven operation) in the mining truck field, the heat dissipation system must simultaneously meet the multiple heat dissipation requirements of the engine, battery pack, and electric drive unit. Existing rigid mining trucks typically use a front-mounted radiator, placed at the very front of the engine compartment. While this direct exposure to airflow results in high heat dissipation efficiency, it also makes the radiator susceptible to collision damage. Therefore, front-mounted radiators require protection with a water tank cover.

[0005] Existing water tank cover structures mostly adopt a two-piece rectangular grid design or a single-cavity through-type structure. During maintenance, the tank must be completely disassembled to access the core components of the radiator. At the same time, the single-cavity through-type structure is prone to problems such as turbulence of heat dissipation airflow and hot air recirculation within the cavity, which affects heat dissipation efficiency. Utility Model Content

[0006] The purpose of this disclosure is to provide a hybrid rigid mining truck water tank cover and a rigid mining truck, which can at least solve one of the above-mentioned technical problems.

[0007] To achieve the above objectives, one or more embodiments of this disclosure provide a hybrid rigid mining truck water tank cover, including a water tank cover and a protective mesh assembly bolted to the water tank cover. The water tank cover is composed of a front panel, two side panels, and a supporting frame welded together. The protective mesh assembly includes a heat dissipation mesh and a shaped plate. The shaped plate and the heat dissipation mesh are detachably connected. A partition is provided between the heat dissipation mesh and the heat exchanger.

[0008] Furthermore, a connecting angle steel is provided at the connection between the protective net assembly and the water tank cover.

[0009] Furthermore, the bottom of both sides of the water tank cover is provided with a connecting seat that connects to the front platform of the cover.

[0010] Furthermore, the bottom of the front panel of the water tank cover is provided with connection holes for installing lamp guards.

[0011] Furthermore, the surface of the heat dissipation mesh has a hexagonal mesh structure.

[0012] Furthermore, the partition is welded to the water tank cover.

[0013] Furthermore, the shaped plate and the heat dissipation mesh are bolted together.

[0014] Furthermore, the lighting protection net includes a headlight protection net and a fog light protection net, both of which are made of round steel welded to plate to form a semi-enclosed protective structure.

[0015] Furthermore, the top of the water tank cover is provided with a water inlet with a splash guard.

[0016] Another aspect of this disclosure provides a rigid mining truck, which includes the above-described hybrid rigid mining truck water tank cover and hybrid power system, wherein the hybrid power system includes a generator, a power battery and an electric drive device.

[0017] The beneficial effects of one or more of the above technical solutions are as follows:

[0018] This disclosure improves the overall rigidity of the water tank cover by welding the support frame and the frame structure formed by the front panel and side panels, which can withstand the mechanical impact and vibration under the complex road conditions in the mining area; the protective net assembly and the water tank cover are connected by bolts to achieve modular disassembly and assembly, which facilitates quick maintenance and replacement; the partition set by the cavity between the heat dissipation net and the heat exchanger effectively isolates the heat source and avoids hot air backflow, ensuring heat dissipation stability.

[0024] like Figures 1-3 As shown, this embodiment provides a hybrid rigid mining truck water tank cover, including a water tank cover 1 and a protective net assembly bolted to the water tank cover 1. A connecting angle steel is provided at the connection between the protective net assembly and the water tank cover 1. The protective net assembly is welded to one side of the angle steel, and the other side of the angle steel is provided with bolt mounting holes and is bolted to the water tank cover 1. This ensures the connection strength while enabling modular disassembly and assembly, facilitating maintenance and replacement.

[0025] like Figure 1 and Figure 2 As shown, the water tank cover 1 is composed of a front panel, two side panels, and a supporting frame welded together. The welding connection allows the supporting frame to form a frame structure with the front panel / side panels, improving the overall rigidity and resisting mechanical impacts and vibrations under complex road conditions in the mining area.

[0026] The bottom of both sides of the water tank cover 1 is provided with connecting seats 6 that connect to the front platform of the cover, forming a stable docking with the front platform of the cover and effectively dispersing the gravity load of the equipment; the top of the water tank cover 1 is provided with a water inlet 8 with a splash guard; effectively preventing water from splashing during the water filling process, ensuring cleanliness and safety during use; the bottom of the front panel of the water tank cover 1 is provided with connecting holes for installing lamp guards, including headlight guards 4 and fog light guards 5. Both headlight guards 4 and fog light guards 5 are made of round steel and plate welded to form a semi-enclosed protective structure. The lamp guards welded with round steel and perforated plate can improve the impact energy that can be withstood. They can be detached and installed by fitting with the headlight / fog light guards through the connecting holes.

[0027] like Figure 2 and Figure 3 The described protective mesh assembly includes a heat dissipation mesh 2 and a styling plate 3. The styling plate 3 is detachably connected to the heat dissipation mesh 2 for easy maintenance and replacement. A partition 7 is provided between the heat dissipation mesh 2 and the heat exchanger to effectively isolate the heat dissipation mesh 2 from the engine, ensuring the engine's normal operating temperature. This avoids the turbulence and hot air recirculation problems that easily occur in single-cavity through-type structures. Furthermore, the partition 7 is welded to the water tank cover 1, ensuring the stability and durability of the entire protective mesh assembly.

[0028] The heat dissipation mesh 2 has a hexagonal mesh structure. The hexagonal honeycomb structure of the heat dissipation mesh 2 achieves uniform stress distribution and improves tensile strength.

[0029] The molding plate 3 and the heat dissipation mesh 2 are bolted together, which allows for quick disassembly of the molding plate 3 and maintenance and replacement of the heat dissipation mesh 2 under different working conditions.

[0030] This embodiment also provides a rigid mining truck, including the above-mentioned hybrid rigid mining truck water tank cover and hybrid power system, wherein the hybrid power system includes a generator engine, a power battery and an electric drive device.

[0031] Working principle of this utility model:

[0032] During vehicle operation, the heat source end of the radiator is on the engine side, and the heat dissipation space is small. The heat flow will flow into the cavity between the frame and the engine to form a vortex. There is a cavity between the cold source side of the front end of the radiator and the heat dissipation mesh 2. The inlet of the cavity at the front end of the radiator is blocked by the partition 7, which effectively prevents the hot air from flowing back from the heat source side, thus reducing the heat dissipation efficiency of the radiator.

[0033] While the specific embodiments of this disclosure have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this disclosure. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this disclosure are still within the scope of protection of this disclosure.
