Description

Technical Field

[0001] This application belongs to the field of vehicle engineering technology, and specifically relates to an integrated fuel tank. Background Technology

[0002] In underground thin coal seam operations, the overall size of engineering vehicles is relatively small due to the limited space in the roadways. Currently, engineering vehicles are often equipped with a single large-volume hydraulic oil tank to meet the hydraulic system's oil requirements. This results in a significant occupation of the vehicle's internal space, making the layout of other components difficult and easily leading to a messy and tangled situation of internal pipes and wiring harnesses. This not only affects the overall aesthetics of the vehicle but also significantly reduces maintenance convenience due to the forced non-optimal layout of components, causing numerous inconveniences for later vehicle maintenance. Furthermore, when it is necessary to add actuators to existing vehicles, or when the oil consumption of existing actuators increases, the original hydraulic oil tank's volume cannot meet the new requirements and cannot satisfy the usage requirements of the added actuators.

[0029] Beneficial effects:

[0030] The integrated oil tank provided in the embodiments of this utility model allows for the elimination of the need for an auxiliary oil tank when the hydraulic oil capacity in the main oil tank meets the usage requirements of the engineering vehicle, without affecting the original vehicle model's operation. When the hydraulic oil capacity in the main oil tank is insufficient, the auxiliary oil tank is installed. When the hydraulic oil in the main oil tank is insufficient, the hydraulic oil in the auxiliary oil tank automatically flows into the main oil tank under gravity, replenishing the hydraulic oil. Furthermore, the vent port ensures that air inside the main oil tank is expelled after the oil enters, preventing air from entering the main oil tank and avoiding pump cavitation during operation, which could damage the pump and cause vehicle downtime.

[0040] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0041] See also Figures 1-4 As shown, according to an embodiment of this application, an integrated fuel tank is provided, which is mounted on an engineering vehicle frame and includes:

[0042] Main fuel tank 1 is mounted on the engineering vehicle frame, and an oil inlet and an exhaust outlet are provided on the top surface of the main fuel tank 1.

[0043] Auxiliary fuel tank 2 is detachably mounted on the engineering vehicle frame. An oil outlet is provided on the auxiliary fuel tank 2, which is located above the main fuel tank 1.

[0044] It also includes a connecting component 3, which is located between the oil outlet and the oil inlet.

[0045] Specifically, the main oil tank 1 is securely mounted on the engineering vehicle frame to directly supply hydraulic oil to the hydraulic system of the engineering vehicle. The auxiliary oil tank 2 is detachably mounted on the engineering vehicle frame, and can be further installed on the mudguard of the engineering vehicle frame. When the hydraulic oil capacity in the main oil tank 1 meets the usage requirements of the engineering vehicle, the auxiliary oil tank 2 does not need to be installed and will not affect the use of the original model. When the hydraulic oil capacity in the main oil tank 1 cannot meet the usage requirements, the auxiliary oil tank 2 is installed. The installation position of the auxiliary oil tank 2 should ensure that the oil outlet on the auxiliary oil tank 2 is located in the same direction as the main oil tank 1. After the auxiliary oil tank 2 is installed on the top surface, the oil outlet of the auxiliary oil tank 2 can be connected to the oil inlet of the main oil tank 1 through the connecting component. When the hydraulic oil in the main oil tank 1 is insufficient, the hydraulic oil in the auxiliary oil tank 2 will automatically flow into the main oil tank 1 under the action of gravity to replenish the hydraulic oil. Moreover, through the setting of the vent, after the oil enters the main oil tank 1, the air inside the main oil tank 1 will be discharged through the vent, preventing air from entering the main oil tank 1. This avoids the pump from sucking in air during use, causing the pump to cavitate, resulting in pump damage and vehicle shutdown.

[0046] An oil filter is installed on the outside of the exhaust port to prevent external impurities from entering the main oil tank 1 during use.

[0047] The main oil tank 1 is equipped with a liquid level sensor to monitor the oil level inside the main oil tank 1. It is equipped with a low oil level alarm. When the oil level inside is lower than the set limit, an alarm will be triggered to remind the driver that there is not enough oil in the tank. At this time, there may be abnormalities such as oil leakage in the pipeline. It is necessary to stop the machine to check for faults. If not handled, it may cause the pump to fail to draw oil, resulting in pump cavitation and damage to the pump.

[0048] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the connecting component 3 includes:

[0049] Connecting barb 31 is provided on the main oil tank 1 and connected to the oil inlet;

[0050] The first connecting pipe 32 is disposed between the connecting barb 31 and the oil outlet.

[0051] Specifically, the connecting component 3 includes a connecting barb 31 and a first connecting pipe 32. The connecting barb 31 is used to connect to the oil inlet on the top surface of the main oil tank 1. One end of the first connecting pipe 32 is connected to the oil outlet of the auxiliary oil tank 2, and the other end is connected to the oil inlet of the main oil tank 1, so as to realize the connection between the oil inlet of the main oil tank 1 and the oil outlet of the auxiliary oil tank 2, so as to facilitate the flow of hydraulic oil in the auxiliary oil tank 2 into the main oil tank 1.

[0052] The connection position of the first connecting pipe 32 and the connecting barb 31 is not higher than the height of the oil outlet, so that when the hydraulic oil in the main oil tank 1 is insufficient, the hydraulic oil in the auxiliary oil tank 2 can automatically flow into the main oil tank 1 under gravity.

[0053] The first connecting pipe 32 can be a flexible hose or a steel pipe, which can connect the oil outlet to the connecting barb 31.

[0054] Combination Figure 2 As shown, in some embodiments, optionally, the connecting barb 31 includes:

[0055] Barbed base plate 311, the barbed base plate 311 is installed on the main oil tank 1;

[0056] The barbed tube 312 is disposed on the barbed base plate 311. The interior of the barbed tube 312 is connected to the oil inlet. A sealing plate 313 is provided on the top surface of the barbed tube 312.

[0057] Connector 314 is disposed on barbed tube 312 and is connected to first connecting tube 32.

[0058] Specifically, the connecting barb 31 includes a barb base plate 311, a barb tube 312, a sealing plate 313, and a connector 314. The barb base plate 311 is installed on the main oil tank 1 and has a through hole inside, which is connected to the oil inlet. The barb tube 312 is vertically welded to the barb base plate 311 and its interior is connected to the oil inlet of the main oil tank 1. The sealing plate 313 is welded to the top of the barb tube 312, which can seal the barb tube 312 from the top. The connector 314 can be installed on the barb tube 312 by disassembly or welding. One end of the first connecting pipe 32 is connected to the oil outlet of the auxiliary oil tank 2, and the other end is connected to the connector 314 to realize the connection of the oil circuit.

[0059] When the connector 314 and the barbed tube 312 are detachably connected, the connector 314 and the barbed tube 312 are connected by threads, and an oil sealing ring is installed inside to achieve sealing performance after connection. The detachable connection makes it easy to replace the connector 314 according to the usage requirements, making the operation more convenient.

[0060] Combination Figure 1 and Figure 3 As shown, in some embodiments, optionally, the auxiliary fuel tank 2 includes:

[0061] Fuel tank body 21;

[0062] The first filter 22 is disposed on the top surface of the oil tank body 21.

[0063] It also includes a second connecting pipe 4, which is disposed between the exhaust port and the first filter 22.

[0064] Specifically, the first filter 22 is an air filter, which is installed on the top surface of the fuel tank body 21 to balance the air pressure inside and outside the fuel tank body 21. It also has the function of adding oil. When oil needs to be added, the first filter 22 can be removed for oil addition.

[0065] The second connecting pipe 4 is connected to the exhaust port and the first filter 22, which can introduce the gas in the main oil tank 1 and the auxiliary oil tank 2 into the first filter 22 for filtration, remove oil mist and impurities that may be carried in the gas, and then discharge the purified gas to avoid oil mist pollution of the downhole environment. At the same time, it prevents impurities from entering the main oil tank 1 through the exhaust port, and also allows the auxiliary oil tank 2 and the main oil tank 1 to communicate with the outside gas, which facilitates the flow of oil.

[0066] The second connecting pipe 4 can be a flexible hose or a steel pipe.

[0067] Combination Figure 1 and Figure 3 As shown, in some embodiments, the auxiliary fuel tank 2 may optionally include:

[0068] Oil drain plug 23 is located on the side of the oil tank body 21;

[0072] Liquid level sensor 27 is disposed on the top surface of the oil tank body 21 and located on one side of the second filter 26.

[0073] Specifically, the drain plug 23 is installed at a low position on the side of the oil tank body 21 or on the bottom surface of the oil tank body 21, so as to completely drain the hydraulic oil in the oil tank body 21 when disassembling the auxiliary oil tank 2 or replacing internal components. The drain plug 23 is connected to the oil tank body 21 by a threaded connection and is equipped with a fluororubber sealing ring to ensure a tight seal.

[0074] The level gauge 24 is installed on the side of the oil tank body 21 and above the drain plug 23. The scale of the level gauge 24 is clearly visible, which can intuitively display the oil level in the tank. The installation position of the level gauge 24 makes it convenient for operators to quickly check the oil status during vehicle maintenance, avoiding overfilling of oil and overflow when the engineering vehicle is bumpy, or underfilling oil and causing hydraulic system failure. It also provides an accurate level reference for oil draining and refilling operations.

[0075] The cleaning cover 25 is located on one side of the level gauge 24 and is connected to the oil tank body 21 via a rotating buckle. It can be quickly opened or closed with a simple 90° rotation, making operation convenient and efficient. After opening the cleaning cover 25, operators can access the interior of the oil tank body 21 to perform maintenance work such as cleaning impurities and replacing the filter element, greatly improving the maintainability of the auxiliary oil tank 2. The cleaning cover 25 has a sealing groove on its edge, and an O-ring is embedded during assembly to ensure a good sealing effect when closed, preventing oil leakage and the entry of external contaminants.

[0076] The second filter 26 is located on the top surface of the oil tank body 21 and on one side of the first filter 22. The second filter 26 is a return oil filter, which can filter out impurities in the oil returned to the oil tank by the actuator.

[0077] The level sensor 27 is installed on the top surface of the fuel tank body 21 and located on one side of the second filter 26. It can monitor the fuel level in the fuel tank body 21 in real time and transmit the data to the vehicle control system. The level sensor 27 has a high and low level alarm function. When the fuel level reaches the preset high or low level threshold, it will immediately issue an alarm through the vehicle display screen and buzzer to remind the operator to take appropriate measures.

[0080] Specifically, protective covers are provided on the outside of the first filter 22, the drain plug 23, the level gauge 24, the cleaning cover 25, and the second filter 26 to protect them from direct collisions with obstacles during use and to improve the service life of each component.

[0081] Combination Figure 4As shown, in some embodiments, optionally, a connecting plate 5 is provided at the bottom of the fuel tank body 21, and a connecting hole is provided on the connecting plate 5.

[0082] Specifically, the connecting plate 5 is welded to the bottom of the fuel tank body 21. There are two connecting plates 5, which are symmetrically arranged on the fuel tank body 21. The connecting plate 5 is detachably connected to the engineering vehicle frame through a connector, which can be a clip or a screw. When using screws for connection, threaded holes are opened at intervals on the connecting plate 5. The threaded holes are connected to the engineering vehicle frame through the screws, resulting in a strong connection and convenient connection.

[0083] Combination Figure 1 and Figure 3 As shown, in some embodiments, optionally, lifting lugs 6 are provided at the four corners of the top surface of the fuel tank body 21.

[0084] Specifically, the lifting lugs 6 are symmetrically installed in pairs at the four corners of the top surface of the fuel tank body 21, so that the fuel tank body 21 is subjected to more balanced force during hoisting, which improves safety. When installing the fuel tank body 21, it is only necessary to use a lifting tool to hoist the auxiliary fuel tank 2 to the designated position, which is convenient for installation.
