Description

Technical Field

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

[0002] At present, most of the abnormal faults in the operation of the tunnel boring machine are caused by poor lubrication and abnormal wear in the early stage. Therefore, gear oil needs to be added to the tunnel boring machine to prevent tooth surface wear, abrasion, sintering, etc., and 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. This refueling method is inefficient and labor-intensive, and 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 large degree and poor fluidity will cause uneven distribution of gear oil on the gear surface. In addition, the position and size of some refueling holes of the comprehensive excavator may cause inconvenience in operation and oil overflow during refueling, increasing the risk of oil contamination, and the operators need 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 are driven by motors to drive the output of gear oil. The motors may fail in harsh environments such as high temperature and high pressure, and the electric sparks generated when the motors are running can easily cause gas explosions underground. Explosion-proof devices are needed to ensure operation safety, which is inconvenient to use.

[0003] Announcement No. CN214663603U discloses a handheld gear oil filler, which is composed of a cylinder, a piston, a handle, a cavity, an oil inlet check valve and an oil outlet check valve. The handle and the piston are fixedly connected. The piston penetrates 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 check valve and an oil outlet check valve. The oil inlet check valve is composed of a blocking ball I, a spring I and an oil inlet hole. The oil outlet check valve is composed 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, and 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 opened, 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 opened, the pressure is positive pressure, and the filler is the process of alternating switching of the oil inlet one-way valve and the oil outlet one-way valve; Announcement No. CN218913683U discloses an automatic gear oil filler, including a filling shell, the inner side of the upper end surface 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 surface 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 arranged on the inner side of the filling tank, so as to facilitate preheating of the gear oil inside the filling tank. A transmission shaft is arranged at the center of the inner wall of the filling tank, and filter blades are arranged at the four ends of the transmission shaft. A brush is arranged at one end of the filter blade close to the inner wall of the filling tank, so as to facilitate the transmission shaft to rotate and drive the filter blade to stir the gear oil inside the filling tank. The gear oil filling device uses a motor drive during operation to drive the output of the gear oil. The motor may fail in harsh environments such as high temperature and high pressure. At the same time, the seal of the motor may not be able to withstand the pressure difference, resulting in leakage of lubricating oil or external pollutants entering the motor, affecting normal operation and refueling effect. The motor drive device involves electrical components, and there are safety hazards such as short circuit and leakage. Especially in harsh environments, these risks are more prominent, and a large amount of gear oil is exposed to the air for a long time, which will reduce the lubrication performance and service life of the gear oil. Air mixed in the gear oil is also easy to form foam, which affects the compressibility of the gear oil and may cause insufficient oil supply. Summary of the invention

One end of the connecting column (14) is rotatably connected to the sealing plate (1) via a bearing, and the connecting column (14) passes through the windshield plate (18) and is connected to the other end of the lead screw (24). The inner ring surface of the first sealed bearing (17) is fixedly placed on the side surface of the middle part of the connecting column (14), and the outer ring surface of the first sealed bearing (17) is fixedly connected to the inner ring surface of the windshield plate (18).

Preferably, the cross-sectional diameter of the filling hemisphere (15) increases gradually in an arc shape from one end to the half thereof, and remains constant from the half thereof to the other end. The filling hemisphere (15) and the container (7) are coaxially arranged. The filling vane (16) is fixedly placed on the side of the connecting column (14), the filling vane (16) is placed between the sealing plate (1) and the wind shield (18), and the top end of the filling vane (16) is connected to the bottom surface of the filling hemisphere (15). Preferably, a plurality of the filling blades (16) are provided, and the plurality of the filling blades (16) are arranged at equal distances along the circumference of the connecting column (14). The filling blades (16) are in a sheet-like structure. The width of the filling blades (16) gradually increases in an arc shape from the top to the five-sixths position, and gradually decreases in an arc shape from the five-sixths position to the bottom. The width of the top of the filling blade (16) is the same as the cross-sectional ring width of the bottom end of the filling hemisphere (15).

Preferably, the filling impeller (16) has a rough surface. The homing hemisphere (25) is fixed on the side surface of the connecting column (14) near the bottom end through a through hole opened in the middle. Preferably, the homing hemisphere (25) and the filling hemisphere (15) are symmetrically arranged with respect to the wind deflector (18). The homing blade (19) is fixedly placed on the side of the connecting column (14), the homing blade (19) is placed between the connecting plate (6) and the wind deflector (18), and the homing blade (19) and the filling blade (16) are in a mirror image structure; Preferably, the homing blade (19) has a rough surface; Preferably, the airflow entering the filling air cylinder (2) flows in the opposite direction of the filling wheel blade (16), and the airflow entering the homing air cylinder (13) flows in the opposite direction of the homing wheel blade (19); When in use, during the gear oil filling process, the stop valve (10) on the filling port (11) is first closed to prevent the gear oil from overflowing from the filling port (11). Then, the stop valve (10) on the oil outlet (9) is opened, and the filling sealing cover (3) is removed. The air inlet pipe and the filling air cylinder (2) are connected, and the high-speed airflow under the mine is used to act on the filling impeller (16) to drive the connecting column (14) to rotate, thereby driving the lead screw (24) to rotate, so that the thread in the movable sleeve (21) and the lead screw (24) cooperate, thereby driving the filling plate (22) to move downward. As the filling plate (22) moves downward, pressure is applied to the gear oil in the container (7), so that the gear The oil flows out from the oil outlet (9). When the gear oil in 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 airflow acts on the return impeller (19) to drive the connecting column (14) to rotate in the opposite direction, so that the filling plate (22) moves 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); 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; The design in which one end of the support rod (8) first extends vertically downward to a halfway point and then extends obliquely downward in a straight line in the opposite direction of the central axis to the other end can enhance the stability of the overall device and prevent it from tipping over; 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 completely as possible, thereby 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; The diameter of the filling plate (22) is slightly smaller than the diameter of the inner side surface of the container (7), and a sealing strip is arranged on the side surface of the filling plate (22). The side surface of the sealing strip is in contact with the inner side surface 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 inside 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; A rubber cushion layer is disposed under the filling plate (22). The rubber cushion layer is designed to be thicker than 5 mm and can play a buffering role when the filling plate (22) contacts the bottom of the container (7), thereby reducing damage to the container (7) and the filling plate (22) caused by impact force. At the same time, the thick rubber cushion layer can undergo a large elastic deformation when it touches the bottom, thereby squeezing the residual gear oil and effectively removing the gear oil residue at the bottom of the container (7); The windshield (18) is fixedly placed on the inner side of the sealing cylinder (4), and a second sealing bearing (20) is placed between the windshield (18) and the connecting column (14), so that the windshield (18) can be isolated from top to bottom, thereby preventing the air from flowing into the other end during the process of the airflow at one end affecting the filling of the impeller (16) or the impeller, thereby causing the impeller to fail to rotate and affecting the filling of the gear oil; The top of the filling wheel blade (16) is connected to the bottom of the filling hemisphere (15), and the hemispherical shape can effectively reduce air resistance, making the operation of the filling wheel blade (16) more stable; The filling blade (16) is in a sheet-like structure, and the width of the filling blade (16) gradually increases in an arc shape from the top to the five-sixths position, and gradually decreases in an arc shape from the five-sixths position to the bottom. The wider middle portion can provide sufficient power for the filling blade (16) to drive the lead screw (24) to rotate, and the narrower ends help reduce resistance; The filling wheel blade (16) has a 5-degree twist from the top to the third of the connecting column (14) in the axial direction, and has a 45-degree twist from the third of the connecting column (14) to the bottom of the connecting column (14) in the axial direction. 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 fan blade, so as to provide a more uniform and stable torque output throughout the entire rotation cycle. 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 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 fluid separation, and more effectively converting wind energy into rotational kinetic energy of the screw (24); The design of the filling wheel blade (16) cooperating with the return wheel blade (19) to form a wind-driven rotational power for the lead screw (24) can avoid directly injecting mine air into the container (7) to cause gear oil contamination, 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 air injection during the process of filling relatively viscous gear oil, thereby improving the gear oil filling efficiency; The purpose is to provide motive power for the pneumatic component through wind energy, drive the filling component to operate through the pneumatic component, and thus output the gear oil evenly and continuously.

4. A mine compressed air driven low residual gear oil filling station according to claim 1, characterized in that The diameter of the filling plate is slightly smaller than the diameter of the inner side of the container, and a sealing strip is arranged on the side of the filling plate. The side of the sealing strip is in contact with the inner side of the container. The sealing strip has an elastic deformation force, which enables the filling plate to be close to the inner wall of the container during the downward movement, thereby preventing the gear oil from remaining inside the container and maintaining the cleanliness of the inner wall of the container. The elastic deformation of the sealing strip can scrape off the gear oil adhering to the inner wall of the container, and the friction force is small under the lubrication of the gear oil. The height of the filling plate is less than the height of the moving sleeve, and a rubber pad is arranged under the filling plate. The thickness of the rubber cushion layer is greater than 5mm, which can play a buffering role when the filling plate contacts the bottom of the container, reducing the damage of the impact force to the container and the filling plate. At the same time, the thicker rubber cushion layer can undergo a larger elastic deformation when touching the bottom, squeeze the residual gear oil, and effectively remove the gear oil residue at the bottom of the container. The refueling port is communicated with the container, and the oil outlet is communicated with the container. A stop valve is also provided on the container, and two stop valves are provided, one of which is connected to the refueling port, and the other is connected to the oil outlet.

9. A mine compressed air driven low residual gear oil filling station according to claim 1, characterized in that The cross-sectional diameter of the filling hemisphere increases gradually in an arc shape from one end to the half, and remains unchanged from the half to the other end. The filling hemisphere and the container are coaxially arranged. There are multiple filling vanes, and the multiple filling vanes are arranged equidistantly along the circumference of the connecting column. The filling vanes are sheet-like structures. The width of the filling vanes increases gradually in an arc shape from the top to the five-sixths, and decreases gradually in an arc shape from the five-sixths to the bottom. The width of the top of the filling vane is the same as the cross-sectional ring width of the bottom end of the filling hemisphere. The filling vane has a 5-degree twist along the axial direction of the connecting column from the top to the one-third, and a 45-degree twist along the axial direction of the connecting column from the one-third to the bottom. The wider middle part can provide sufficient power for the filling wheel blade to drive the rotation of the screw, and the narrower two ends help reduce resistance; the twisted blades can absorb more airflow and provide sufficient power for the rotation of the screw, while helping to generate different torques at different parts of the fan blades, so as to provide more uniform and stable torque output throughout the rotation cycle; the filling wheel blade has a rough surface, and the return wheel blade and the filling wheel blade have a mirror structure. The rough surface of the return wheel blade can increase the adhesion of the wind flow and increase the friction between the fluid and the blade surface, which is conducive to the formation of a stable boundary layer of the fluid on the blade, reducing fluid separation, and more effectively converting wind energy into the rotational kinetic energy of the screw.

10. A mine compressed air driven low residual gear oil filling station according to claim 1, characterized in that The design of the filling wheel blade cooperating with the return wheel blade to form wind-driven rotational power for the screw can avoid gear oil contamination caused by directly injecting mine air into the container, and at the same time avoid the situation in which the gear oil at the air outlet position is emptied while the gear oil at other positions does not flow due to direct air injection during the filling of relatively viscous gear oil, thereby improving the gear oil filling efficiency.
