Technical Field

[0001] The present application relates to the technical field of extreme cold bulldozers, and in particular to an auxiliary starting system for extreme cold bulldozers. Background Art

[0002] Bulldozer is a kind of earth-moving machinery that can dig, transport and dump rock and soil. It has a wide range of uses in open-pit mines. For example, it is used to build dumps, level automobile dumps, pile up scattered ore and rock, level work platforms and construction sites, etc. It is not only used for auxiliary work, but also for main mining work. For example: stripping and mining of sand ore beds, traction and boosting of scrapers and plows, and lowering the height of stripping steps in cooperation with other earth-moving machinery when there is no transportation mining method.

[0003] When the bulldozer needs to be started, the battery supplies power to the electric starter motor, which drives the electric starter motor to rotate at high speed, thereby driving the engine crankshaft to rotate, compressing the air and diesel mixed combustible gas in the engine cylinder to ignite, start the engine, and the bulldozer can work normally; but in extremely cold conditions, the battery power decays significantly, and often the vehicle cannot be started after being parked overnight. At the same time, the battery has to supply power to systems such as fuel heating and intake heating, which greatly shortens the battery life and greatly affects the normal use of the bulldozer in extremely cold conditions.

[0004] Therefore, there is an urgent need for an auxiliary starting system for extreme cold bulldozers to solve the problem that the battery activity of the current bulldozer is reduced and the capacity is greatly attenuated under extremely low temperature conditions, and it is difficult to start the bulldozer when the vehicle is turned off or after transportation, and other vehicles are often required to assist in starting.

[0020] It should be understood by those skilled in the art that the embodiments described below are only preferred embodiments of the present disclosure, and do not mean that the present disclosure can only be implemented through the preferred embodiments. The preferred embodiments are only used to explain the technical principles of the present disclosure, and are not used to limit the protection scope of the present disclosure. Based on the preferred embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present disclosure.

[0021] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0022] The technical solution proposed in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0023] Figure 1 The present invention provides an auxiliary starting system for an extreme cold bulldozer. Figure 1 As shown, the system provided in the embodiment of the present application mainly includes: a controller 1, an ambient temperature sensor 2, an intelligent meter 3, a battery 4, an engine 5, an air compressor 6, an air tank 7, a pressure sensor 8, and an air motor 9.

[0024] It should be noted that:

[0025] The controller 1 is connected to the ambient temperature sensor 2, the intelligent meter 3, the battery 4, the engine 5, the air compressor 6, the gas tank 7 and the pressure sensor 8 respectively, and can be any feasible device or apparatus capable of controlling other devices, such as a single-chip microcomputer chip, etc. It can control the gas tank 7 to control the air motor 9 to start alone, the air motor 9 and the battery 4 to start together, the battery 4 to start and other multi-working mode control, so as to realize energy-saving green control.

[0026] The ambient temperature sensor 2 is a device or apparatus capable of performing temperature detection and is used to detect the external ambient temperature.

[0027] The smart meter 3 is a pressure data display meter, which is used to display the pressure value of the pressure sensor 8 through the controller 1 .

[0028] The storage battery 4 is an existing storage battery 4 , and can detect the voltage of the storage battery 4 and upload it to the controller 1 .

[0029] The engine 5 is also connected to the air motor 9 and the air compressor 6. Specifically, the air compressor 6 can be installed at the flywheel of the engine 5 or at the transfer case of the bulldozer. An electromagnetic clutch is installed at the connection between the air compressor 6 and the power device to control the connection and disconnection of the air compressor 6 and the engine 5. The air motor 9 can be installed at the starting gear of the engine 5.

[0030] The gas tank 7 is also connected to the air motor 9, the pressure sensor 8 and the air compressor 6. The pressure sensor 8 of the gas tank 7 detects the pressure of the gas tank 7 in real time and feeds back the pressure value to the controller 1 to control the electromagnetic clutch between the air compressor 6 and the engine 5, thereby ensuring that the air pressure in the gas tank 7 is within the design pressure range. When the ambient temperature sensor 2 detects that the ambient temperature is lower than the temperature T or the controller 1 detects that the voltage of the battery 4 is lower than U, the starting battery 4 is insufficient and the vehicle cannot be started. At this time, the controller 1 controls the gas tank 7 to supply high-pressure compressed air to the air motor 9, driving the air motor 9 to rotate at a high speed instantly, completing the auxiliary start of the engine 5. As an example, the gas tank 7 is connected to the air motor 9 and the air compressor 6 with a hose. In order to resist low temperature, the hose in this application can be made of low-temperature resistant silicone material. In addition, in order to reserve an accessory pipeline interface on the gas tank 7, the radiator compressed air cleaning or vehicle maintenance pneumatic tools can be connected through the quick pipeline interface during vehicle maintenance.

[0031] The pressure sensor 8 is any feasible device or apparatus capable of detecting the pressure in the gas storage tank 7 .

[0032] Based on the above description, those skilled in the art can understand that the present application discloses an auxiliary starting system for an extreme cold type bulldozer, a controller 1, an ambient temperature sensor 2 connected to the controller 1, an intelligent instrument 3, a battery 4, an engine 5, an air compressor 6, an air tank 7 and a pressure sensor 8; wherein the engine 5 is also connected to an air motor 9 and an air compressor 6, and the air motor 9, the pressure sensor 8 and the air compressor 6 are also connected to the air tank 7.

[0033] The specific operation process is as follows: during normal operation, the pressure sensor 8 detects the pressure of the air tank 7 in real time and feeds back the pressure value to the controller 1 to control the on and off of the electromagnetic clutch between the air compressor 6 and the engine 5, thereby ensuring that the air pressure in the air tank 7 is within the design pressure range. When the ambient temperature sensor 2 detects that the ambient temperature is lower than the temperature T or the controller 1 detects that the voltage of the battery 4 is lower than U, the starting battery 4 is insufficient and the vehicle cannot be started. At this time, the controller 1 controls the air tank 7 to supply high-pressure compressed air to the air motor 9, driving the air motor 9 to rotate at high speed instantly, completing the auxiliary start of the engine 5; the controller 1 starts the air motor 9 alone, the air motor 9 and the battery 4 electric motor start together, and the battery 4 electric motor starts independently; an accessory interface is reserved on the air tank 7, and the radiator compressed air cleaning or vehicle maintenance pneumatic tools can be connected through the quick interface during vehicle repair and maintenance.

Without departing from the technical principles of the present disclosure, those skilled in the art can split and combine the technical solutions in the above-mentioned various embodiments, and can also make equivalent changes or replacements to the relevant technical features.
