Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings. In the description of the present application, it is to be understood that the terms "upper", "lower", "left", "right", "front", "rear", "horizontal", "vertical", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings.
The specific embodiment is as follows:
the hydraulic oil tank with the oil quantity monitoring function shown in fig. 1 comprises a shell 1, wherein a cylindrical oil tank 2 is arranged inside the shell 1, the upper end of the oil tank is an open end, the edge of the open end of the upper end of the oil tank is connected with the inner side of the top of the shell 1 through a flexible connection 9, and the flexible connection 9 can be realized through a silica gel cloth flexible connection. The tank bottom of the oil tank 2 is planar, a weighing sensor 3 is arranged at the middle position of the tank bottom of the oil tank 2, and the weighing sensor 3 can adopt a resistance strain type weighing sensor. An oil inlet pipe 4 and an oil outlet pipe 6 are arranged on the top of the shell 1 in a penetrating mode, one end of the oil inlet pipe 4 is located in the shell 1 and is placed in the oil tank 2, one end, located outside the shell 1, of the oil inlet pipe 4 is connected with an electromagnetic valve 5, and the oil inlet pipe 4 is opened or closed through controlling the electromagnetic valve 5. The end of the oil outlet pipe 6 located inside the housing 1 extends to the bottom of the oil tank 2, and in order to prevent impurities existing at the bottom of the oil tank 2 from entering the oil outlet pipe 6 after a long time use, a filter screen 12 may be provided at the end of the oil outlet pipe 6 located at the bottom of the oil tank 2. An oil pump 7 is connected to one end of the oil outlet pipe 6 outside the housing 1, and when oil needs to be taken out from the oil tank 2, the oil pump 7 is started to suck out the oil. In order to conveniently monitor the oil amount, a display 8 for displaying the oil amount is arranged on the side wall of the casing 1, and the display 8 can be implemented by a digital tube display or a liquid crystal display.
In order to ensure the stability of the oil tank 2 in the housing 1, a plurality of cylinders 10 for guiding are symmetrically arranged in the circumferential direction at the bottom of the oil tank 2. The symmetric arrangement along the circumferential direction means that when the number of the cylinders 10 is 3, the distance between each cylinder and the center of the bottom surface of the oil tank 2 is equal, and the included angle between two adjacent cylinders along the circumferential direction of the bottom surface of the oil tank is 120 degrees; for another example, when the number of the cylinders 10 is 4, the distance between each cylinder and the center of the bottom surface of the oil tank 2 is equal, and the included angle between two adjacent cylinders along the circumferential direction of the bottom surface of the oil tank is 90 degrees. When the air cylinder 10 is arranged at the bottom of the oil tank 2, the height between the air cylinder 10 and the weighing sensor 3 may be mismatched, so that a base 11 is arranged at the bottom of the housing 1, and the weighing sensor 3 is arranged on the base 11.
The oil quantity monitoring of the hydraulic oil tank is realized in the following way:
the weighing sensor 3 weighs the oil tank 2, and the weight of the oil tank 2 minus the weight of the tank body of the oil tank 2 is the weight of the hydraulic oil in the oil tank 2. Then the weight of the hydraulic oil is converted into the volume of the hydraulic oil, and the volume formula of the cylinder can convert the hydraulic oil with a certain volume into the height of the hydraulic oil in the oil tank 2 on the premise of knowing the area of the bottom surface of the oil tank 2. Finally, the height value of the hydraulic oil is displayed by a display 8 under the electrical control.
