[0014] The present invention provides an automatic lubricating oil filling device for mining equipment. When in use, the base structure is installed near the part that needs lubrication through the connecting hole thereon. When filling oil, the servo motor located on the outer frame is started, and the servo motor starts to drive the angle rotating shaft to rotate. The rotation of the angle rotating shaft drives the inner frame and the dust plate to rotate. When it rotates to the required angle, the servo motor stops running. At this time, the angle of the rotating cylinder is rotated to the opening to align with the oil filling position, and the electric telescopic rod is started. The electric telescopic rod starts to drive the toggle gear to move. The movement of the toggle gear first drives the first large lift angle threaded cylinder to rotate, and the first large lift angle threaded cylinder is rotated. The rotation of the angle thread barrel drives the closing plate to rotate and open along the direction of the guide rail. During the rotation and opening process, the inner side of the closing plate will wipe the nozzle of the oil nozzle. When the closing plate is fully opened, the toggle tooth disengages from the first large-angle thread barrel and moves to the second large-angle thread barrel.

After the oil nozzle is further accurately aligned with the position where oil needs to be injected, the electric telescopic rod stops running, and the oil injection device starts to deliver lubricating oil to the oil nozzle, and the oil nozzle injects lubricating oil to the position where oil needs to be injected. After the oil injection is completed, the oil injection device is turned off and the electric telescopic rod is started again to run in the reverse direction. The electric telescopic rod runs in the reverse direction to drive the toggle gear to reset. During the reset of the toggle gear, the second large lift angle threaded barrel is first reset. The reset of the second large lift angle threaded barrel drives the oil nozzle to move into the connecting barrel. When the oil nozzle is reset, the toggle gear disengages from the second large lift angle threaded barrel and moves to the first large lift angle threaded barrel to engage with the first large lift angle threaded barrel. The toggle gear continues to move to drive the first large lift angle threaded barrel to reset. The reset of the first large lift angle threaded barrel drives the closing plate to rotate and reset along the guide rail, and The nozzle of the fuel injector is wiped to prevent the fuel injector from being contaminated by dust and other impurities generated by the internal environment of the mine during the oil filling process, thereby ensuring the smooth flow of the fuel injector. At the same time, the closing plate is completely closed to prevent the mine environment from affecting the unused fuel injector. When the closing plate is closed, the electric telescopic rod stops running, and the servo motor is started. The servo motor reverses to drive the angle rotation shaft to rotate, and the angle rotation shaft drives the inner frame and the dustproof plate to rotate and reset. At this time, the dustproof plate, the angle rotation shaft and the base structure constitute a closed environment to prevent dust from entering the inner frame and affecting the internal parts, thereby improving the service life of the present invention.

[0015] Compared with the prior art, the present invention can set the rotation angle of the servo motor and the oil filling amount of the oil filling structure according to actual conditions during installation, and set the oil filling amount in advance according to different oil filling positions required, thereby realizing the timing, quantitative, point-by-point automatic and intelligent lubrication functions of the lubrication parts of various mechanical equipment in the mine, realizing oil filling automation, liberating labor, improving production efficiency, extending the life of the lubrication parts of the mine fixed device, reducing the equipment failure rate, liberating the status quo of traditional underground manual oiling, reducing maintenance and repair time, saving fixed equipment replacement costs, and at the same time protecting the fuel injector and various components according to the environmental problems of the mine, so that the fuel injector and various components can maintain a good service life and stable use efficiency in complex environments.

[0031] In the present invention, a protective cover 19 is provided on the outside of the servo motor 4. The protective cover 19 is installed on the outside of the servo motor 4 and fixedly connected to the outer frame 1. The protective cover 19 on the outside of the servo motor 4 protects the servo motor 4 from being affected by the complex environment of the mine and allows it to operate normally, thereby improving the service life of the servo motor 4.

[0032] In the present invention, a control panel 20 is provided on the dustproof plate 5. The control panel 20 is installed on the dustproof plate 5 and is electrically connected to the servo motor 4. The control panel 20 is electrically connected to the electric telescopic rod 13. The control panel 20 is electrically connected to the oil filling structure 7. The control panel 20 can facilitate users to operate the oil filling automation of the present invention.

[0033] In the present invention, the two guide rails 15 on the inner frame 6 are respectively located at the upper and lower ends of the inner frame 6 and correspond to each other, and the closing plates 16 on the two guide rails 15 are symmetrical to each other.

[0034] Through the use of wires by those skilled in the art, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components are electrically connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0035] In this embodiment, the use steps of the present invention are divided into the following steps: Step 1: Before installing the device of the present invention, fix the base structure 2 near the part that needs lubrication. The fixed position is selected to be a position that is close to the lubrication part and does not affect the operation of the equipment. The base structure 2 that is compatible with it can be replaced according to the shape of the fixed position (such as a flat surface, an arc surface or a special-shaped surface). When replacing, tighten the fastening bolts 204 and pull the plug 201 out of the outer frame 1. After replacing the fixing plate 202 of the required shape, reinsert the plug 201 into the outer frame 1 and tighten the fastening bolts 204 to fix the position of the plug 201. At this time, the device of the present invention can be fixed near the part that needs lubrication through the connecting hole 203 on the fixing plate 202. Specifically, the device of the present invention can be fixed by passing a bolt, a clamp or a rope through the connecting hole 203, or the device of the present invention can be fixed near the part that needs lubrication by the suction cup electromagnet 205 on the fixing plate 202. Specifically, the suction cup electromagnet 205 is energized to cause it to be adsorbed and fixed near the part that needs lubrication.

[0036] Step 2: After installing the present invention, the rotation angle of the servo motor 4 and the oil filling amount of the oil filling structure 7 are set according to actual conditions. According to the required mine equipment and the oil filling position, the rotation angle of the servo motor 4 and the oil filling amount of the oil filling structure 7 are set in advance on the control panel 20. The rotation angle of the servo motor 4 is based on the ability to align the oil nozzle 8 with the oil filling position, and the oil filling amount of the oil filling structure 7 is based on the actual requirements of the mine equipment and the oil filling position, and the oil is stored in the oil storage cylinder 701 in advance through the oil storage port 702.

[0037] Step 3: Before oiling is required, start the servo motor 4 located on the outer frame 1. The servo motor 4 starts to drive the angle rotating shaft 3 to rotate. The protective cover 19 on the outside of the servo motor 4 protects the servo motor 4 from being affected by the complex environment of the mine and operates normally, thereby improving the service life of the servo motor 4. The angle rotating shaft 3 rotates to drive the inner frame 6 and the dust plate 5 to rotate. When it rotates to the angle set in advance, the servo motor 4 stops running. At this time, the angle of the rotating cylinder 10 rotates to the oiling position, and then the electric telescopic rod 13 starts to drive the toggle gear 12 to move. The movement of the toggle gear 12 first drives the first large lift angle threaded cylinder 11 to rotate. The rotation of the first large lift angle threaded cylinder 11 drives the rotating cylinder 10 to rotate. The rotation of the rotating cylinder 10 drives the closing plate 16 to rotate and open along the direction of the guide rail 15. The process of the closing plate 16 from closed to open is as follows Figure 5 As shown; during the process of rotating and opening, the wiping block 18 on the inner side of the closing plate 16 will wipe the mouth of the fuel injector 8. When the closing plate 16 is fully opened, the toggle tooth 12 disengages from the first large-angle threaded cylinder 11 and moves to the second large-angle threaded cylinder 14. At this time, the toggle tooth 12 drives the second large-angle threaded cylinder 14 to rotate, and the rotation of the second large-angle threaded cylinder 14 drives the fuel injector 8 engaged with it to move toward the outside of the opening of the rotating cylinder 10. The limit block 17 on the fuel injector 8 enables the fuel injector 8 to move more stably along the specified direction until the fuel injector 8 is further accurately aligned with the position where oil needs to be injected, and the electric telescopic rod 13 stops running.

[0038] Step 4: When the oil filling starts, the oil filling device 7 starts to transport lubricating oil to the oil nozzle 8, and the oil nozzle 8 fills the position that needs lubrication with oil. When the oil filling device 7 starts, the pump in the oil storage cylinder 701 transports the oil in the oil storage cylinder 701 along the connecting oil pipe 703 and the telescopic tube 705 to the oil nozzle 8. The connecting oil pipe 703 is a hose, and the pipe inlet 704 prevents dust from entering the inside of the connecting cylinder 9 through the gap, and plays a sealing function. The telescopic tube 705 can provide telescopic range for the movement of the oil nozzle 8.

[0039] Step 5: After the oil filling is completed, the oil filling device 7 is closed and the electric telescopic rod 13 is started to run in the reverse direction. The electric telescopic rod 13 runs in the reverse direction to drive the toggle tooth 12 to reset. In the process of resetting the toggle tooth 12, the second large lift angle threaded cylinder 14 is first driven to reset. The reset of the second large lift angle threaded cylinder 14 drives the oil nozzle 8 to move into the connecting cylinder 9. When the oil nozzle 8 is reset, the toggle tooth 12 is disengaged from the second large lift angle threaded cylinder 14 and moves to the first large lift angle threaded cylinder 11 to engage with the first large lift angle threaded cylinder 11. The toggle tooth 12 continues to move to drive the first large lift angle threaded cylinder 11 to reset. The reset of the first large lift angle threaded cylinder 11 drives the closing plate 16 to rotate along the guide rail 15 Turn to reset, and wipe the mouth of the fuel injector 8 to prevent the fuel injector 8 from being contaminated by dust and other impurities generated by the internal environment of the mine during the oiling process, to ensure the smooth flow of the fuel injector 8, and at the same time, the closing plate 16 is completely closed to prevent the mine environment from affecting the unused fuel injectors. When the closing plate 16 is closed, the electric telescopic rod 13 stops running, and the servo motor 4 is started. The servo motor 4 reverses to drive the angle rotation shaft 3 to rotate, and the angle rotation shaft 3 is reset to drive the inner frame 6 and the dustproof plate 5 to rotate and reset. At this time, the dustproof plate 5, the angle rotation shaft 3, the base structure 2, and the outer frame 1 constitute a closed environment to prevent dust from entering the inner frame 6 and affecting the internal parts.
