Description

Technical Field

[0001] The present application relates to the technical field of hydraulic oil detection, and in particular to a hydraulic oil tank, a rotary drilling rig and an alarm method. Background Art

[0002] The main working medium of the current rotary drilling rig is hydraulic oil. The hydraulic actuators include pumps, valves and other parts. When the hydraulic oil passes through the contraction section of the valve port, the pressure at the section decreases, causing a large amount of air to precipitate from the hydraulic oil, resulting in cavitation.

[0003] When these small bubbles enter the hydraulic oil tank through the oil return system, they accumulate in the hydraulic oil tank. When the machine is working, these small bubbles will be carried to the high-pressure areas such as the pump room, valves and hoses along with the hydraulic oil. Due to the increase in pressure, the volume of the bubbles will shrink sharply or burst, and the air in the bubbles will be integrated into the hydraulic oil again. At the moment of gas bursting, high temperature and high pressure will be generated, and hydraulic shock will occur, resulting in cavitation, causing peeling and corrosion on the surface of hydraulic components, reducing the service life of pumps, valves and hoses, and increasing the maintenance cost of the whole machine. Summary of the invention

[0038] Embodiment 1

[0039] See also Figures 1 to 3As shown, the hydraulic oil tank provided by the present application includes an oil tank body 101, an oil return cylinder 102, a bubble sensor 103 and an alarm device 104; the oil return cylinder 102 is arranged in the oil tank body 101, and is used to filter the hydraulic oil; the oil outlet 105 of the oil return cylinder 102 is connected to the oil tank body 101, so that the hydraulic oil flows from the oil return cylinder 102 into the oil tank body 101; the bubble sensor 103 is installed in the oil tank body 101 and immersed in the hydraulic oil, and the bubble sensor 103 is used to detect the bubble content of the hydraulic oil in the oil tank body 101; the bubble sensor 103 is electrically connected to the alarm device 104, and when the bubble content exceeds a preset value, the alarm device 104 sends an alarm message.

[0040] Specifically, the hydraulic oil tank includes an oil tank body 101, an oil return cylinder 102, a bubble sensor 103 and an alarm device 104. The oil return cylinder 102 is provided with an oil inlet and an oil outlet 105. The hydraulic oil enters the oil return cylinder 102 from the oil inlet, and enters the oil tank body 101 from the oil outlet 105 after being filtered. When the hydraulic oil flows out from the oil outlet 105, the pressure decreases, causing gas to precipitate from the hydraulic oil, thereby generating bubbles. A bubble sensor 103 is provided in the oil tank body 101 to detect the bubble content of the hydraulic oil. When the bubble content is small, the impact on the hydraulic components is small, and the alarm device 104 does not work. When the bubble content increases to a preset value, the impact on the hydraulic components is large, and the alarm device 104 sends an alarm message to notify the operator to handle it.

[0041] The hydraulic oil tank provided in the present application has a bubble sensor 103 disposed in the tank body 101 to detect the bubble content of the hydraulic oil. When the bubble content is too high, the operator is notified through the alarm device 104 to prevent excessive bubbles from causing damage to the hydraulic components.

[0042] In an optional solution of this embodiment, the bubble sensor 103 is installed on the side wall of the oil tank body 101 , and the movement path of the bubbles in the hydraulic oil can pass through the detection range of the bubble sensor 103 .

[0043] Generally speaking, the oil inlet of the oil return cylinder 102 is located at the top, and the oil outlet 105 is located at the bottom. When the hydraulic oil is discharged from the oil outlet 105, bubbles are generated from the oil outlet 105. The bubble density is small and thus the bubbles move upward. In this embodiment, the bubble sensor is installed on the side wall of the oil tank body 101. When the bubbles rise, the bubbles can pass through the detection range of the bubble sensor 103, thereby more accurately detecting the bubble content.

[0044] In an optional solution of this embodiment, the alarm device 104 includes an electrically connected controller 106 and a display screen 107; the controller 106 is electrically connected to the bubble sensor 103, and when the bubble content in the hydraulic oil exceeds a preset value, the controller 106 controls the display screen 107 to display an alarm message.

[0045] Specifically, the hydraulic oil tank is installed on the vehicle frame, and the display screen 107 can be installed in the vehicle's cab. When the bubble content in the hydraulic oil exceeds a preset value, the controller 106 receives a signal and feeds back the result to the display screen 107 in the cab, reminding the driver that the bubble content in the tank is currently high and whether to take measures to eliminate the bubbles.

[0046] In an optional solution of this embodiment, the alarm device 104 also includes an alarm sound generator; the alarm sound generator is electrically connected to the controller 106, and when the bubble content in the hydraulic oil exceeds a preset value, the controller 106 controls the alarm sound generator to output an alarm sound.

[0047] In this embodiment, an alarm sound generator is also provided, so that when the driver fails to notice the information on the display screen 107 while driving the vehicle, the driver can be reminded by sound.

[0048] Embodiment 2

[0049] The second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment are not described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0050] See also Figure 2 and Figure 3 As shown, in an optional scheme of this embodiment, a defoaming device 108 is also included; the defoaming device 108 is installed in the oil tank body 101 and immersed in the hydraulic oil, and the defoaming device 108 is used to eliminate bubbles in the hydraulic oil to reduce the bubble content in the hydraulic oil and prevent excessive bubbles from causing damage to the hydraulic components.

[0051] In an optional solution of this embodiment, the defoaming device 108 is electrically connected to the controller 106. When the bubble content exceeds a preset value, the controller 106 can control the defoaming device 108 to eliminate bubbles in the hydraulic oil. When the bubble content is small, the impact on the hydraulic components is small, and the defoaming device 108 can be stopped to save energy; when the bubble content increases to a preset value, the impact on the hydraulic components is large, and the defoaming device 108 needs to be started for defoaming. In this embodiment, the defoaming device 108 is electrically connected to the controller 106 to realize the automatic defoaming operation.

[0052] It should be noted that bubbles with smaller diameters are easy to separate out from the hydraulic oil, and small bubbles are easy to be integrated into the hydraulic oil again, while bubbles with larger diameters are not easy to be integrated into the hydraulic oil. Optionally, the defoaming device 108 can realize the aggregation of bubbles with smaller diameters into bubbles with larger diameters, so that large bubbles are not easy to be integrated into the hydraulic oil, thereby avoiding the influence of bubbles on the hydraulic actuator.

[0053] In an optional solution of this embodiment, a start switch is further included, which is electrically connected to the defoaming device 108 and is used to start the defoaming device 108. The driver can manually control the start of the defoaming device 108. When the driver receives an alarm message, he can click the start switch to start the defoaming device 108, and the defoaming device 108 is powered on to perform a bubble discharge operation.

[0054] An optional solution of this embodiment further includes an adsorbent 109 ; the adsorbent 109 is located in the oil tank body 101 , and the adsorbent 109 is arranged at the oil outlet 105 , and the adsorbent 109 is used to adsorb bubbles.

[0055] In this embodiment, the adsorption member 109 is arranged at the oil outlet 105. Preferably, the adsorption member 109 is in a plate shape and is arranged around the oil outlet 105. The bubbles discharged from the oil outlet 105 can be immediately adsorbed on the surface of the adsorption member 109 to prevent the bubbles from following the hydraulic oil to flow to the hydraulic actuator.

[0056] In an optional solution of this embodiment, the defoaming device 108 is installed on the surface of the adsorbent 109 and faces the oil outlet 105. A large number of bubbles are produced at the oil outlet 105. The defoaming device 108 is installed on the surface of the adsorbent 109 and faces the oil outlet 105, which can eliminate the bubbles in time and has a better defoaming effect.
