Technical Field

[0001] The utility model relates to an integrated water-cooled electric control box structure, in particular to an integrated water-cooled electric control box structure taking into account installation efficiency, reliability and aesthetics, and belongs to the field of mining machinery and equipment. Background Art

[0002] With the proposal of my country's "dual carbon" goals and people's increasing attention to environmental protection, some pure electric mining dump trucks have appeared in the field of mining transportation in recent years, achieving good energy-saving effects. However, these new energy mining trucks have problems such as short driving range for heavy-load uphill conditions, and frequent recharging affects operational efficiency. The extended-range mining dump truck uses the power generation and recharging function of the range extender to greatly reduce the charging frequency of the vehicle and improve the vehicle's attendance rate and driving range. However, since the extended-range mining dump truck contains components such as the range extender power generation module, the system is more complex than that of a pure electric mining truck, and there are more high-power heat dissipation devices, which puts higher requirements on the topological configuration and structural design of the heat dissipation system.

[0003] In the prior art, high-power equipment such as generator controllers, drive motor controllers, and voltage converters are distributed, and cooling pipes need to be extended to different parts to connect with the water inlets and outlets of the equipment, resulting in a large number of cooling pipes on the vehicle frame and difficulty in fixing them. The cooling pipes are inefficient and difficult to install, and are prone to misconnection. While affecting the precision and aesthetics of the frame pipe lines, they are also prone to cross-interference with other pipe lines such as hydraulic pipes, increasing the risk of wear and failure and affecting the stability of the vehicle operation. Summary of the invention

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides an integrated water-cooled electric control box structure which takes into account installation efficiency, reliability and aesthetics.

[0011] The cooling pipeline is connected to the box frame through bolts and clamps, and is also connected to the water inlet and outlet of the controller and the voltage converter through a throat clamp.

[0012] In some embodiments, the number of the fixing plates is two, which are symmetrically arranged at the left and right ends of the box frame, and each fixing plate is provided with a plurality of bolt holes.

[0013] In some embodiments, the cooling pipeline is composed of a metal shaped hard pipe and a rubber hose.

[0014] In some embodiments, the controller includes an all-in-one controller, a generator controller and a drive motor controller; after the cooling pipes of the all-in-one controller, the generator controller, the drive motor controller and the voltage converter are connected, a group of cooling interfaces for docking with the entire vehicle is left.

[0015] In some embodiments, the all-in-one controller and the voltage converter are located in the upper space of the box frame, the generator controller is located in the middle space of the box frame, and the drive motor controller is located in the bottom space of the box frame.

[0016] In some embodiments, at least one triangular reinforcement angle is provided between the fixing plate and the box frame.

[0017] In some embodiments, the box frame is welded together by rectangular square tubes and U-shaped channel steels, and the rectangular square tubes are pre-embedded with nut columns for fixing the box cover and the lifting ears in corresponding positions by bolts.
