Description

Technical Field

[0001] The present invention relates to a mine compressed air driven low-residue gear oil filling station, which involves a pneumatic filling device capable of automatically filling gear oil through wind energy. The invention belongs to the technical field of gear oil filling, and particularly relates to a gear oil pneumatic filling device that uses wind energy to provide motive force for a pneumatic component, drives the filling component to operate through the pneumatic component, and thus outputs the gear oil evenly and continuously. Background Art

[0002] At present, during the operation of the tunnel boring machine, most of the abnormal faults are caused by poor lubrication and abnormal wear in the early stage. Therefore, the tunnel boring machine needs to be filled with gear oil to prevent tooth surface wear, abrasion, sintering, etc., and to extend its service life. However, there are some problems in the process of gear oil filling. First, gear oil filling is generally completed by manual filling, which is inefficient and labor-intensive. In addition, the gear oil is exposed to the air for a long time, which will reduce the lubrication performance and service life of the gear oil. Secondly, when the tunnel boring machine is repaired and supplemented with 320 heavy-duty gear oil, the 320 gear oil will become sticky due to the viscosity of the gear oil. The larger the density and the poorer the fluidity, the uneven distribution of gear oil on the gear surface will occur. In addition, the position and size of some refueling holes in the tunnel boring machine may lead to inconvenience in operation and oil overflow during refueling, increasing the risk of oil contamination, and the operator needs to work in an unstable or unsafe posture, which increases the safety risk. There are some automatic filling devices on the market, but most of them use motors to drive the output of gear oil. The motor may malfunction in harsh environments such as high temperature and high pressure, and the electric sparks generated when the motor is running can easily cause underground gas explosions. Explosion-proof devices need to be installed to ensure operational safety, which is inconvenient to use.

[0003] Announcement No. CN214663603U discloses a handheld gear oil filler, which consists of a cylinder, a piston, a handle, a cavity, an oil inlet one-way valve and an oil outlet one-way valve. The handle and the piston are fixedly connected. The piston passes through the cylinder from one end of the cylinder. A groove is provided on the outer surface of the piston. The oil seal is embedded in the groove. The other end of the cylinder is provided with an oil inlet one-way valve and an oil outlet one-way valve. The oil inlet one-way valve consists of a blocking ball I, a spring I and an oil inlet hole. The oil outlet one-way valve consists of a blocking ball II, a spring II and an oil outlet hole. The aperture cross-sections of the oil inlet hole and the oil outlet hole are equal, and the diameters of the blocking balls I and II are larger than the oil inlet hole and the oil outlet hole, respectively. The diameter of the hole, blocking ball I blocks the oil inlet hole, blocking ball II blocks the oil outlet hole, the suction generated by pulling and the pressure generated by pushing are equal, the oil inlet one-way valve is open, the oil outlet one-way valve is closed, the suction is negative pressure, the oil inlet one-way valve is closed, the oil outlet one-way valve is open, the pressure is positive pressure, the filler is the oil inlet one-way valve and the oil outlet one-way valve alternating switching process; Announcement No. CN218913683U discloses an automatic gear oil filler, including a filling shell, the inner side of the upper end face of the filling shell is provided with a mounting groove, the inner side of the mounting groove is provided with a filling tank, and the two ends of the upper end face of the filling tank are respectively provided with a discharge port and a feed port. A heat conducting plate and a heating copper wire are provided on the inner side of the filling tank, thereby facilitating the preheating of the gear oil inside the filling tank. A transmission shaft is provided at the center of the inner wall of the filling tank, and filter blades are provided at each of the four ends of the transmission shaft. A brush is provided at one end of the filter blade, which is in close contact with the inner wall of the filling tank, so that when the transmission shaft rotates, the filter blades are driven to stir the gear oil inside the filling tank. The gear oil filling device is driven by a motor during operation to drive the output of the gear oil. The motor may malfunction in harsh environments such as high temperature and high pressure. At the same time, the seals of the motor may not be able to withstand the pressure difference, resulting in lubricating oil leakage or external contaminants entering the motor, affecting normal operation and refueling effect. The motor drive device involves electrical components, which have safety hazards such as short circuit and leakage. These risks are particularly prominent in harsh environments. Moreover, large amounts of gear oil exposed to air for a long time will reduce the lubrication performance and service life of the gear oil. Air mixed in the gear oil is also prone to forming foam, which affects the compressibility of the gear oil and may lead to insufficient oil supply. Summary of the Invention

[0100] The filling hemisphere (15) is fixed on the side of the connecting column (14) near the top through the through hole in the middle.

[0101] Preferably, the cross-sectional diameter of the filling hemisphere (15) increases gradually from one end to the half thereof in an arc shape, and remains unchanged from the half thereof to the other end thereof. The filling hemisphere (15) and the container (7) are coaxially arranged.

[0103] Preferably, the filling vane (16) is provided in plurality, and the plurality of the filling vanes (16) are arranged equidistantly along the circumference of the connecting column (14). The filling vane (16) is in a sheet-like structure, and the width of the filling vane (16) increases gradually in an arc shape from the top to the five-sixths position, and decreases gradually in an arc shape from the five-sixths position to the bottom.

[0108] Preferably, the homing blade (19) has a rough surface;

[0109] Preferably, the airflow entering the filling air cylinder (2) flows in the opposite direction of the filling vane (16), and the airflow entering the homing air cylinder (13) flows in the opposite direction of the homing vane (19);

[0110] When in use, during the gear oil filling process, first close the stop valve (10) on the oil filling port (11) to prevent the gear oil from overflowing from the oil filling port (11), then open the stop valve (10) on the oil outlet (9), remove the filling sealing cover (3), connect the air inlet pipe and the filling air cylinder (2), and use the high-speed air flow under the mine to act on the filling wheel blade (16) to drive the connecting column (14) to rotate, thereby driving the screw (24) to rotate, so that the thread in the movable sleeve (21) and the screw (24) cooperate, thereby driving the filling plate (22) to move downward, and as the filling plate (22) moves downward, it will exert pressure on the gear oil inside the container (7), so that the gear The oil flows out from the oil outlet (9). When the gear oil inside the container (7) is insufficient, the stop valve (10) on the oil outlet (9) is closed, and the stop valve (10) on the refueling port (11) is opened to relieve the pressure inside the container (7). The filling sealing cover (3) is fixed to the filling air cylinder (2), and the return sealing cover (12) is removed. The air inlet pipe and the return air cylinder (13) are connected. The air flow acts on the return blade (19) to drive the connecting column (14) to rotate in the opposite direction, thereby moving the filling plate (22) upward until the filling plate (22) reaches above the oil inlet. At this time, the container (7) can be refueled through the refueling port (11);

[0111] The oil inlet is combined with a stop valve (10) to release pressure inside the container (7) after refueling is completed, thereby reducing resistance when the filling plate (22) rises;

[0112] The design of one end of the support rod (8) first extending vertically downward to halfway and then extending obliquely downward in a straight line in the opposite direction of the central axis to the other end can enhance the stability of the entire device and prevent it from tipping over;

[0113] The design of placing the oil outlet (9) at the bottom of the container (7) can ensure that the gear oil in the container (7) flows out as much as possible, avoiding waste due to residue, and at the same time preventing the gear oil from accumulating at the bottom for a long time, thereby affecting the lubrication effect;

[0114] The diameter of the filling plate (22) is slightly smaller than the diameter of the inner side of the container (7), and a sealing strip is provided on the side of the filling plate (22). The side of the sealing strip contacts the inner side of the container (7). The sealing strip has an elastic deformation force design, which enables the filling plate (22) to be closely attached to the inner wall of the container (7) during the downward movement, thereby preventing the gear oil from remaining on the inside of the container (7) and maintaining the cleanliness of the inner wall of the container (7). The elastic deformation of the sealing strip can scrape off the gear oil adhering to the inner wall of the container (7), and at the same time, the friction force is small under the lubrication of the gear oil.

[0115] A rubber pad is provided below the filling plate (22). The thickness of the rubber pad is greater than 5 mm, and can play a buffering role when the filling plate (22) contacts the bottom of the container (7), reducing the damage to the container (7) and the filling plate (22) caused by the impact force. At the same time, the thicker rubber pad can undergo a larger elastic deformation when it touches the bottom, squeezing the residual gear oil and effectively removing the gear oil residue at the bottom of the container (7);

[0116] The windshield (18) is fixedly placed on the inner side of the sealing cylinder (4), and a second sealing bearing (20) is provided between the windshield (18) and the connecting column (14), which can isolate the windshield (18) from the top and bottom, thereby preventing the air from flowing into the other end during the process of the airflow at one end acting on the filling blade (16) or being attributed to the blade, thereby causing the blade to malfunction and affecting the filling of the gear oil;

[0117] The design of connecting the top of the filling vane (16) and the bottom of the filling hemisphere (15) and the hemispherical shape can effectively reduce air resistance, making the operation of the filling vane (16) more stable;

[0118] The filling vane (16) is in a sheet-like structure, and the width of the filling vane (16) increases gradually in an arc shape from the top to the five-sixths position, and decreases gradually in an arc shape from the five-sixths position to the bottom. The wider part in the middle can provide sufficient power for the filling vane (16) to drive the screw (24) to rotate, and the narrower ends help reduce resistance;

[0119] The filling blade (16) has a 5-degree twist from the top to the third of the blade along the axial direction of the connecting column (14), and a 45-degree twist from the third of the blade to the bottom of the blade along the axial direction of the connecting column (14). The twisted blade can receive more airflow and provide sufficient power for the rotation of the lead screw (24), and at the same time helps to generate different torques at different parts of the blade, so as to provide a more uniform and stable torque output throughout the entire rotation cycle.

[0120] The rough surface of the filling blade (16) and the rough surface of the homing blade (19) can increase the adhesion of the wind flow and increase the friction between the fluid and the blade surface, thereby facilitating the formation of a stable boundary layer of the fluid on the blade, reducing the fluid separation phenomenon, and more effectively converting wind energy into the rotational kinetic energy of the screw (24);

[0121] The filling blade (16) cooperates with the return blade (19) to form a wind-driven rotational power design of the lead screw (24), which can avoid the gear oil being polluted by directly injecting mine air into the container (7), and at the same time avoid the situation in which the gear oil at the air outlet position is emptied and the gear oil at other positions does not flow due to direct injection of air during the process of filling relatively viscous gear oil, thereby improving the gear oil filling efficiency;

[0122] The purpose is to provide motive power for the pneumatic components through wind energy, drive the filling components to operate through the pneumatic components, and thus output the gear oil evenly and continuously.

[0123] It should be noted that, unless otherwise expressly specified or limited, the terms "placed in," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections such as hemming, rivet connection, pin connection, adhesive connection, and welding connection; detachable connections such as threaded connection, snap connection, and hinge connection; or integral connection; electrical connection; direct connection; indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
