Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lubrication equipment, and more specifically, to an automatic chain lubrication device. Background Art
[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction. Chain-shaped objects used to block traffic passages (such as in streets, rivers or harbor entrances), and chains used for mechanical transmission. During operation, the chain generates mechanical friction during use, resulting in wear, so lubricating oil is needed to reduce mechanical friction, reduce wear, and increase the service life of the equipment.
[0003] For example, the authorization announcement number CN218023847U discloses an automatic chain lubrication device, which respectively sets a proximity switch and a nozzle at the upper and lower positions opposite to each other on the inner side of the chain, installs an electromagnetic oil valve in the oil pipe connected to the nozzle, and adopts a controller to be electrically connected to the proximity switch and the electromagnetic oil valve respectively. After the proximity switch senses that the chain pin of the chain is approaching, it sends a switch signal to the controller, and the controller immediately opens the electromagnetic oil valve to spray lubricating oil on the other chain pin directly below to implement fixed-point lubrication, and closes after a delay of several seconds, thereby achieving precise lubrication and saving lubricating oil. Compressed air is used as the power source for spraying lubricating oil, which is low in cost. After the proximity switch senses that the chain pin of the chain is approaching, it sends a switch signal to the controller, and the controller immediately opens the electromagnetic air valve to spray lubricating oil quickly, achieving rapid response, so that the chain pin of the chain can be lubricated in time, improving lubrication efficiency and improving wear conditions.
[0004] In the above solution, the nozzle can only lubricate the chain pins, and during use, other positions of the chain will also rust. Although fixed-point lubrication and precise lubrication of the lubricating oil are achieved, the spraying method will still cause waste of the lubricating oil. Utility Model Content

[0022] like Figure 1 to Figure 2 As shown,
[0023] The automatic chain lubrication device comprises a chain 1 and a fixing frame 2 placed on the side of the chain 1. A shell 3 is provided on the fixing frame 2. The shell 3 is formed by connecting two plates. By fixing the fixing frame 2 on the side of the chain 1, the position of the shell 3 is fixed to prevent the shell 3 from affecting the transmission of the chain 1.
[0024] An oil storage tank 4 is provided on the end face of the shell 3, and an accommodating space 5 is provided inside the oil storage tank 4. An oil filling hole 6 is opened on the oil storage tank 4, and a sealing cover 7 is connected to the oil filling hole 6. The sealing cover 7 is plugged into the oil filling hole 6. The oil filling hole 6 is connected to the accommodating space 5. Oil outlet holes 8 are opened on both sides of the oil storage tank 4, and the oil outlet holes 8 are connected to an oil filling pipe 9. The oil filling pipe 9 is provided with a solenoid valve 10 for controlling the outflow of lubricating oil.
[0025] A docking hole 11 is provided on the end face of the shell 3 corresponding to the oil outlet hole 8, and the other end of the oil filling pipe 9 is connected to the docking hole 11. The shell 3 has a cavity 12 inside, and the chain 1 passes through the cavity 12. The cavity 12 is connected to the docking hole 11, and a lubrication component is provided in the cavity 12, and the chain 1 is oiled through the lubrication component.
[0026] The lubrication assembly includes a brush 13 and a sponge strip 14. The brush 13 is arranged corresponding to the docking hole 11. The sponge strip 14 is placed directly below the brush 13. Electric push rods 17 are arranged at both ends of the sponge strip 14. An extrusion plate 18 is arranged at the output end of the electric push rod 17. The extrusion plate 18 is arranged corresponding to the sponge strip 14 and is used to squeeze out the lubricating oil absorbed by the sponge strip 14.
[0027] The electric push rod 17 is electrically connected to a timer 19, and the timer 19 is electrically connected to the solenoid valve 10. The time set on the timer 19 corresponds to the maximum time for the sponge bar 14 to be fully absorbed by the lubricating oil. By setting a suitable time, when the set time is reached, the solenoid valve 10 is closed to stop the delivery of the lubricating oil, and at the same time the electric push rod 17 starts working to squeeze out the lubricating oil in the sponge bar 14.
[0028] A connecting column 20 is adhered to the lower end surface of the sponge strip 14, one end of the connecting column 20 is placed on the inner wall of the cavity 12, and guide holes 21 are provided on both sides of the connecting column 20. The guide holes 21 pass through the lower end surface of the shell 3, and a protective cover 24 is provided on the guide hole 21. The diameter of the protective cover 24 is larger than the diameter of the guide hole 21 to prevent the lubricating oil squeezed out of the sponge strip 14 from contaminating the shell 3.
[0029] An oil receiving box 22 is provided on the lower end surface of the housing 3 corresponding to the guide hole 21, and the squeezed lubricating oil is transported to the oil receiving box 22, thereby avoiding the waste of lubricating oil.
[0030] The oil receiving box 22 is connected to the lower end surface of the shell 3 by screws. A water level alarm 23 is provided on the inner wall of the oil receiving box 22. The water level alarm 23 is electrically connected to the solenoid valve 10. When the lubricating oil in the oil receiving box 22 is reserved to a predetermined amount, the water level alarm 23 sounds an alarm. At the same time, the solenoid valve 10 stops working, making it convenient for the operator to remove the oil receiving box 22 and pour out the lubricating oil in the oil receiving box 22.
[0031] The brush 13 includes a rod body 15 and bristles 16 integrally formed with the rod body 15 . The rod body 15 is detachably connected to the inner wall of the cavity 12 . The rod body 15 is provided with a plurality of through holes for the lubricant to flow out. The lubricant flowing out of the through holes wets the bristles 16 , making it easier for the bristles 16 to lubricate the chain 1 .
[0032] Working principle: When in use, separate the two plates, then wrap the plates on the chain 1, and then fix the two plates together, and align the chain 1 with the bristles 16. Since the housing 3 is connected to the fixing frame 2, the chain 1 will not be affected when it is working. Then the solenoid valve 10 is started, and the lubricating oil flows out from the oil outlet 8, flows into the docking hole 11 through the oil filling pipe 9, and then wets the bristles 16 through the through hole on the rod body 15. The wetted bristles 16 can lubricate the chain 1 passing through. The two sides of the chain 1 are in conflict with the bristles 16 and the sponge strip 14 respectively, and the excess lubricating oil is absorbed by the sponge strip 14. When the sponge strip 14 absorbs a predetermined amount of lubricating oil, the lubricating oil will be absorbed by the sponge strip 14. When lubricating oil is added, the solenoid valve 10 stops working, and the electric push rod 17 drives the extrusion plate 18 to squeeze the sponge strip 14 to squeeze the lubricating oil in the sponge strip 14. The squeezed lubricating oil flows into the oil receiving box 22 through the guide hole 21. When the lubricating oil in the oil receiving box 22 is collected to a set amount, the water level alarm sounds an alarm, and the operator takes out the lubricating oil in the oil receiving box 22. At the same time, the brush 13 is detachably connected to the inner wall of the cavity 12. When the brush 13 is worn, it can be replaced. When the lubricating oil in the oil storage tank 4 is used up, the sealing cover 7 is removed and oil is filled into the oil storage tank 4 through the oil filling hole 6. The operation can be completed without removing the oil storage tank 4.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any common changes and substitutions made by those skilled in the art within the technical solution of the present invention should be included in the protection scope of the present invention.
