An oil tank and a construction machine according to some embodiments of the present invention will be described below with reference to fig. 1.
Example one
The embodiment provides an oil tank which is used for engineering mechanical equipment, and is particularly suitable for an excavator.
Referring to fig. 1, the fuel tank includes a main fuel tank 1, a sub-fuel tank 2, a first liquid level detection element 3, a control valve 4, and a control device 6.
The main oil tank 1 is internally used for storing hydraulic oil, the side wall of the main oil tank 1 is provided with a side-suction main pump oil suction port 7, and the main pump oil suction port 7 is used for communicating a main pump to supply oil to the main pump.
The first liquid level detection element 3 is disposed in the main oil tank 1 and is configured to detect a liquid level in the main oil tank 1, for example, the first liquid level detection element 3 may specifically be a liquid level sensor.
The auxiliary oil tank 2 is also used for storing hydraulic oil, the auxiliary oil tank 2 is fixedly arranged inside the main oil tank 1, and the auxiliary oil tank 2 is located in the upper space inside the main oil tank 1. Because main oil tank 1 is when designing, in order to satisfy main oil tank 1 slope not oil spilling, 15% ~ 20% surplus space can be reserved on the inside upper portion of main oil tank 1, and bellytank 2 sets up in this surplus space with the mode of built-in little oil tank to in time mend oil to main oil tank 1 when the interior fluid of main oil tank 1 reduces. Such design on the one hand make full use of oil tank inner space, increased the holistic volume of oil tank, on the other hand can reduce the height of oil tank (need not to set up the cavity structure in the oil tank bottom for promoting minimum liquid level height), improves the structural stability of oil tank. In addition, the distance from the bottom of the auxiliary fuel tank 2 to the bottom of the main fuel tank 1 is preferably 80% -85% of the height of the main fuel tank 1, so that the auxiliary fuel tank 2 can fully utilize the residual space inside the main fuel tank 1, and the arrangement of the auxiliary fuel tank 2 is more reasonable.
The control valve 4 is arranged at an oil discharge port of the auxiliary oil tank 2, and the control valve 4 is used for controlling whether the auxiliary oil tank 2 is communicated with the main oil tank 1 or not, namely when the control valve 4 is opened, oil in the auxiliary oil tank 2 can flow to the main oil tank 1 from the control valve 4; when the control valve 4 is closed, the secondary fuel tank 2 and the main fuel tank 1 are not communicated. Preferably, in order to avoid the situation that the oil in the main oil tank 1 flows to the auxiliary oil tank 2 when the oil tank shakes or the amount of the oil in the main oil tank 1 is large, the control valve 4 of the present embodiment is configured as a check valve. In addition, in order to ensure that all the oil in the auxiliary oil tank 2 can flow out, the oil discharge port of the auxiliary oil tank 2 is arranged at the bottom of the auxiliary oil tank 2, that is, the control valve 4 is also arranged at the bottom of the auxiliary oil tank 2.
The control device 6 is in communication connection (wired communication connection or wireless communication connection) with the first liquid level detection element 3 and the control valve 4 respectively to acquire a liquid level signal detected by the first liquid level detection element 3 and perform processing, and the processing outputs a control signal to the control valve 4 to control the opening and closing of the control valve 4. Specifically, assuming that the liquid level in the main oil tank 1 reaches the predetermined level 5, the predetermined level 5 is not lower than the position of the main pump suction port 7 of the main oil tank 1, i.e., the predetermined level 5 is higher than or equal to the position of the main pump suction port 7, i.e., a case where the predetermined level 5 is equal to the position of the main pump suction port 7 (the position of the center of the main pump suction port 7) is shown in fig. 1. The first liquid level detection element 3 can acquire the actual liquid level in the main oil tank 1 in real time and transmit an actual liquid level signal to the control device 6, and the control device 6 can compare the actual liquid level signal with the preset liquid level 5 when receiving the actual liquid level signal; if the actual liquid level is less than (or lower than) the preset liquid level 5, it indicates that the oil in the main oil tank 1 cannot be fully supplied to the main pump, and the main pump may have a risk of air suction, and meanwhile, the control device 6 controls the control valve 4 to be opened so as to supplement oil to the main oil tank 1 at the first time, so that the liquid level of the oil in the main oil tank 1 rises, and air-separated oil supply can be realized for the main pump. When the actual liquid level is greater than or equal to (reaches or is higher than) the preset liquid level 5, the control device 6 controls the control valve 4 to be closed, and the auxiliary oil tank 2 does not supplement oil to the main oil tank 1 any more. In the control process, the control device 6, the first liquid level detection element 3, the control valve 4 and the auxiliary oil tank 2 form a minimum liquid level control feedback system, the minimum liquid level in the main oil tank 1 can be guaranteed to be always above a main pump oil suction opening 7 through the system, the main pump is not prone to being sucked, and therefore the stability and the service life of hydraulic components utilizing the oil tank to supply oil are prolonged.
It should be noted that the control device 6 may be a controller with data information comparison and transmission in the prior art.
In addition, in order to facilitate oil replenishment of the main oil tank 1 and the auxiliary oil tank 2, oil replenishment ports (not shown) are respectively formed in the main oil tank 1 and the auxiliary oil tank 2. Preferably, an oil supplementing port of the main oil tank 1 is formed in the top of the main oil tank 1 and is communicated with a first oil supplementing pipe; the oil supplementing opening of the auxiliary oil tank 2 is formed in the top of the auxiliary oil tank 2 and is communicated with the second oil supplementing pipe.
In addition, in order to facilitate understanding of the condition of the oil stored in the secondary tank 2, the present embodiment is provided with a second level detection element (not shown) inside the secondary tank 2 for detecting the level of the oil in the secondary tank 2. The second liquid level detection element may also be a liquid level sensor. Preferably, the second liquid level detection element is also in communication connection with the control device 6, so as to obtain the liquid level information of the second liquid level detection element through the control device 6, when the liquid level in the auxiliary oil tank 2 obtained by the control device 6 is lower than the predetermined liquid level of the auxiliary oil tank 2, the control device 6 may control an oil supplementing device (for example, a second oil supplementing pipe) of the auxiliary oil tank 2 to perform oil supplementing operation, or control a prompting device (for example, an alarm) to send out a prompting message so as to prompt an operator to perform oil supplementing operation.
