Description

Technical Field

[0001] The invention relates to an automatic lubrication device, in particular to an automatic lubrication device used for a transmission mechanism of a peripheral transmission concentrator, and belongs to the technical field of peripheral transmission concentrators. Background Art

[0002] The peripheral transmission thickener is mainly composed of a circular thickening tank and a rake-type scraper. The solid particles suspended in the slurry in the thickening tank settle under the action of gravity, and the upper part becomes clarified water, so that the solid and liquid can be separated. This thickener is widely used in metallurgy, chemical industry, coal, non-metallic mineral processing, environmental protection and other industries. The transmission mechanism of the peripheral transmission thickener transmits the movement and power of the motor to the truss with the rake hanging on it, so that the truss rotates around the center of the tank at a uniform speed and rakes the concentrated product to the discharge port in the center of the tank bottom. The function of the transmission mechanism is to reduce speed and transmit power. It is an important part of the thickener.

[0003] When the transmission mechanism in the prior art drives the truss to rotate, the long-term operation of the reduction gear in the transmission mechanism will cause wear on its tooth surface, which reduces the transmission efficiency. In order to reduce the wear degree of the reduction gear tooth surface and improve the transmission efficiency, the staff will regularly apply lubricating oil to the tooth surface of the reduction gear, thereby increasing the service life of the reduction gear. However, in the prior art, the application of lubricating oil to the tooth surface of the reduction gear is usually done manually. When the lubricating oil is applied to the tooth surface of the reduction gear manually, the entire transmission mechanism needs to be powered off and stopped, which will have a certain impact on the normal operation of the concentrator, and the lubrication effect of the driving gear will be reduced after a period of time. It is necessary to apply the lubricating oil manually multiple times in the future, which is time-consuming and labor-intensive. Summary of the invention

[0029] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Reference Figure 1-7 , an automatic lubrication device for a transmission mechanism of a peripheral transmission concentrator, comprising a truss 1 and a transmission mechanism body, the transmission mechanism body is installed at one end of the truss 1 away from the concentrating tank, the top of the truss 1 is connected to a top plate 2 through a plurality of support rods, and a first lubrication box 4 and a second lubrication box 5 are respectively installed on the top of the top plate 2, an automatic lubrication mechanism is provided on the outer wall of the second lubrication box 5 close to the transmission mechanism body, the automatic lubrication mechanism comprises a push plate 27 installed inside the second lubrication box 5 and a guide pipe 20 installed on the outer wall of the second lubrication box 5, an oil drain port 24 is provided at the bottom of the end of the guide pipe 20 away from the second lubrication box 5, a track 6 used in conjunction with the transmission mechanism body is also provided at the end of the truss 1 away from the concentrating tank, and a cleaning mechanism for cleaning debris on the track 6 is provided near the transmission mechanism body.

[0031] As a technical optimization solution of the present invention, the transmission mechanism body includes a first drive motor 3 installed on the top of the truss 1, and a first drive gear 10 is installed at the output end of the first drive motor 3. A rotating shaft is also rotatably installed on the top of the truss 1, and a second drive gear 11 meshing with the first drive gear 10 is installed at one end of the rotating shaft close to the first drive motor 3, and a roller 7 moving in the track 6 is arranged at one end of the rotating shaft away from the first drive motor 3. After the first drive motor 3 is started, it can drive the first drive gear 10 to rotate, so that the second drive gear 11 meshing with the first drive gear 10 can rotate synchronously. Since the first drive gear 10 is a small gear and the second drive gear 11 is a large gear, the first drive gear 10 can drive the second drive gear 11 to rotate while it can play a certain deceleration effect, and can synchronously drive the rotating shaft and the roller 7 to rotate while the second drive gear 11 rotates. The roller 7 can drive the truss 1 and the rake frame to rotate in the concentration tank while moving in the track 6, so that the concentrated product in the concentration tank can be raked to the discharge port at the center of the tank bottom.

[0032] As a technical optimization solution of the present invention, the automatic lubrication mechanism also includes a rotating block 31 installed on the outer wall of the output end of the first drive motor 3, and an electric telescopic rod 39 is installed inside the rotating block 31, and its protruding end is connected to an arc plate 40, and the bottom end of the push plate 27 is connected to two sliding rods 29, and the bottom ends of both pass through the bottom of the second lubrication box 5 and the top plate 2 and are jointly connected to the moving plate 30, and the outer walls of the two sliding rods 29 are both covered with reset springs 28.

[0033] As a technical optimization scheme of the present invention, a guide rail 21 is installed on the outer wall of one side of the top plate 2 close to the guide pipe 20, and a sealing plate 23 and a partition 25 are slidably installed in the guide rail 21, and a sliding groove is provided on the outer wall on the side where the sealing plate 23 and the partition 25 are close to each other, and a sponge block 22 is detachably installed in the two sliding grooves, and the top of the sponge block 22 is abutted against the oil drain port 24, and a collection box 38 is also installed on the truss 1 directly below the second driving gear 11. When the first drive motor 3 is started, it drives the first drive gear 10 to rotate, and can synchronously drive the rotating block 31 on the outer wall of the output end of the first drive motor 3 to rotate. After the electric telescopic rod 39 is extended by the external remote control, the arc plate 40 is pushed out. When the rotating block 31 rotates, the arc plate 40 in the extended state can be driven to squeeze the moving plate 30 on its top, thereby pushing the slide bar 29 on the top of the moving plate 30 to move up and down, so that the push plate 27 located at the top of the slide bar 29 moves up and down in the second lubrication box 5, and when the push plate 27 moves upward in the second lubrication box 5, the lubricating oil stored in the second lubrication box 5 is pushed upward to the position of the guide pipe 20. The lubricating oil can enter the guide pipe 20 and flow downward to the oil discharge port 24 opened at the bottom of the end of the guide pipe 20 away from the second lubrication box 5, and be discharged into the sponge block 22 through the oil discharge port 24 for adsorption and storage. When the first drive gear 10 rotates, the tooth surface of the first drive gear 10 can be squeezed with the sponge block 22, and the lubricating oil adsorbed and stored in the sponge block 22 is squeezed onto the tooth surface of the first drive gear 10, and it is automatically lubricated, without the need to manually apply the lubricating oil to the tooth surface of the first drive gear 10 multiple times, and there is no need to cut off the power to the entire transmission mechanism body during the work of applying the lubricating oil to the first drive gear 10, so as to avoid affecting the normal operation of the concentrator.When the tooth surface of the first driving gear 10 does not need to be lubricated, the extended end of the electric telescopic rod 39 can be controlled to retract and return to its original position, driving the arc plate 40 to be stored inside the rotating block 31. At this time, the arc plate 40 will not contact the movable plate 30, so that the automatic lubrication mechanism is in a non-working state; and the length of the extended end of the electric telescopic rod 39 can be controlled to adjust the distance between the arc plate 40 and the rotating plate 31, so that the height of the movable plate 30 moving up and down can be adjusted, so that when there is more lubricating oil in the second lubrication box 5 and the first driving gear 10 needs to be lubricated, the extended end of the electric telescopic rod 39 can be controlled by an external remote control to be shorter, so that the rotating block 31 drives the arc plate 40 to rotate to squeeze the movable plate 30. The push plate 27 is pressed to drive the movable plate 30 to move up and down with a smaller amplitude, ensuring that the push plate 27 can push the lubricating oil into the guide tube 20; when the remaining lubricating oil in the second lubrication box 5 is less, the extended end of the electric telescopic rod 39 can be controlled to extend longer by the outer wall remote control, and then when the rotating block 31 drives the arc plate 40 to squeeze the movable plate 30, the movable plate 30 can be driven to move up and down with a larger amplitude, and the push plate 27 can also be driven to push the lubricating oil into the guide tube 20 for discharge, so that when the amount of lubricating oil stored in the second lubrication box 5 is more or less, the push plate 27 can always push the lubricating oil into the guide tube 20 and discharge it into the sponge block 22 during the up and down movement, which is convenient for lubricating the first driving gear 10 and ensures that the lubrication effect is not affected. Moreover, the first driving gear 10 squeezes the sponge block 22 during the rotation process, so that the lubricating oil absorbed in the sponge block 22 is discharged together, and a part of the lubricating oil flows downward along the outer wall of the first driving gear 10 and the second driving gear 11 to the collecting box 38 for collection. On the one hand, this can prevent this part of the lubricating oil from dripping into the concentration tank and polluting the concentration tank; on the other hand, this part of the lubricating oil can be collected in the collecting box 38. When the second driving gear 11 rotates, the tooth surface of the second driving gear 11 will contact the lubricating oil collected in the collecting box 38 and lubricate the tooth surface of the second driving gear 11, so that the lubrication effect of the first driving gear 10 and the second driving gear 11 is further improved, and the waste of this part of the dripping lubricating oil is avoided.

[0034] As a technical optimization solution of the present invention, a receiving groove is provided on the outer wall of the partition 25 close to the sponge block 22, and an extrusion plate 26 is placed in the receiving groove. A hand-held end is provided on the outer wall of the extrusion plate 26 away from the sponge block 22, and the hand-held end is slidably matched with the partition 25. When the sponge block 22 needs to be replaced after being used for a long time, the handheld end is pulled to drive the partition plate 25, the sealing plate 23 and the sponge block 22 installed between the sealing plate 23 and the partition plate 25 to move together on the guide rail 21 toward the end away from the second lubrication box 5 until the sponge block 22 moves out. At this time, the sealing plate 23 just slides to the bottom of the oil drain port 24 to block the oil drain port 24, thereby preventing the remaining lubricating oil in the guide tube 20 from flowing downward and causing waste; after the sponge block 22 moves out, it is slid and removed and a new sponge block 22 is movably inserted into the slide groove of the outer wall on one side close to the sealing plate 23 and the partition plate 25, and then the handheld end is pushed to drive the sealing plate 23, the sponge block 22 and the partition plate 25 to slide and reset on the guide rail 21; and on the transmission mechanism body When the machine stops working and the first driving gear 10 stops rotating, if there is still lubricating oil remaining in the sponge block 22, the handheld end can be pushed to drive the squeezing plate 26 in the storage groove to move toward the second lubrication box 5 to squeeze the sponge block 22, so as to squeeze out the lubricating oil remaining in the sponge block 22, and flow downward along the surface of the first driving gear 10 to the meshing position of the first driving gear 10 and the second driving gear 11 to lubricate the meshing parts, thereby avoiding rust between the meshing first driving gear 10 and the second driving gear 11 when the concentrator is not used for a long time and the transmission mechanism body is not working, and also avoiding the phenomenon that the lubricating oil remaining in the sponge block 22 cannot be automatically squeezed out and waste after the transmission mechanism body is completed.

[0035] As a technical optimization solution of the present invention, the cleaning mechanism includes an arc-shaped cleaning bucket 8, and the bottom of the truss 1 is provided with a fixed plate 15 whose bottom is in contact with the track 6. The arc-shaped cleaning bucket 8 is rotatably installed on the top of the fixed plate 15 through a rotating shaft set at the bottom, and a discharge bucket 37 is also installed at one end of the arc-shaped cleaning bucket 8 close to the truss 1.

[0036] As a technical optimization scheme of the present invention, a second drive motor 12 is installed on the top of the second lubrication box 5, and the output ends of the second drive motor 12 are respectively installed with the first winding roller 13 and the second winding roller 16, the outer wall of the first winding roller 13 is wrapped with a first pull rope 33, and the end away from the first winding roller 13 is installed with a hook 34, the top of the end of the arc cleaning bucket 8 away from the truss 1 is connected to a counterweight 35, and the top of the end of the arc cleaning bucket 8 close to the truss 1 and the top of the counterweight 35 are both installed with a connecting ring 36 matching the hook 34. When there are debris in the track 6 that affects the movement of the roller 7 of the driving mechanism body, the second driving motor 12 can be started to drive the first winding roller 13 to rotate synchronously, so that the first pull rope 33 wrapped around the outer wall of the first winding roller 13 can slowly extend downward, and while the first pull rope 33 extends downward, the arc-shaped cleaning bucket 8 makes one end of the arc-shaped cleaning bucket 8 with the counterweight block 35 slowly rotate downward to the inside of the track 6 until it abuts against the inner bottom surface of the track 6, and the bottom surface of the counterweight block 35 can just fit against the top of the track 6, so that the arc-shaped cleaning bucket 8 can maintain this state in the track 6, and while the conveying mechanism body drives the truss 1 to rotate, the arc-shaped cleaning bucket 8 The bucket 8 can also move synchronously in the track 6, and can automatically scrape the debris in the track 6 while moving, and automatically collect the cleaned debris at the top of the arc-shaped cleaning bucket 8; as more and more debris is collected at the top of the arc-shaped cleaning bucket 8, the debris cleaned subsequently can push the previously cleaned debris downward at the top of the arc-shaped cleaning bucket 8 until the previously cleaned debris is pushed to the position of the discharge bucket 37, and discharged from the discharge bucket 37 to the outside of the track 6, thereby automatically cleaning the debris in the track 6, thereby avoiding the debris from affecting the movement of the roller 7, and ensuring that the rotation of the truss 1 is not affected, thereby improving the working efficiency of the concentrator. In addition, in winter, when the external ambient temperature is low, water may accumulate in the track 6 and condense into ice in a low temperature environment, affecting the movement of the roller 7. In this case, the hook 34 at one end of the first pull rope 33 away from the first winding roller 13 can be connected and matched with the connecting ring 36 provided on the top of the end of the arc cleaning bucket 8 close to the truss 1, and then the second drive motor 12 is started to drive the first winding roller 13 to rotate, so as to reel in the first pull rope 33, and the end of the arc cleaning bucket 8 close to the truss 1 is pulled upward by the first pull rope 33 which moves slowly upward until the arc cleaning bucket 8 is The bottom of one end of the bucket 8 with the counterweight 35 is in contact with the inner bottom surface of the track 6. At this time, the end of the arc-shaped cleaning bucket 8 close to the truss 1 can always be limited and fixed by the first pull rope 33, so that the arc-shaped cleaning bucket 8 can always maintain this state. When the truss 1 rotates to drive the arc-shaped cleaning bucket 8 to move in the track 6, the arc-shaped cleaning bucket 8 can scrape off the ice in the track 6 and ensure its own stability, thereby avoiding the arc-shaped cleaning bucket 8 from shaking up and down when cleaning the ice in the track 6 and being unable to clean the ice.

[0037] As a technical optimization solution of the present invention, a sliding groove 18 is provided at the bottom of one end of the top plate 2 close to the first driving gear 10, and two sliding rods 19 are symmetrically arranged in the sliding groove 18, and a protective curtain 14 is installed at the bottom of the two sliding rods 19.

[0038] As a technical optimization solution of the present invention, two second pull ropes 32 are wrapped around the outer wall of the second winding roller 16, and the ends of the two second pull ropes 32 away from the second winding roller 16 respectively pass through the two sliding rods 19 and the two ends of the protective curtain 14, and the ends of the two pull ropes away from the second winding roller pass through the two ends of the protective curtain 14 and are connected to anti-slip blocks. When the arc-shaped cleaning bucket 8 cleans the debris in the track 6, a large amount of dust will float out from the track 6, and when the second drive motor 12 drives the first winding roller 13 to rotate, it can also synchronously drive the second winding roller 16, so that the second pull rope 32 wrapped around the outer wall of the second winding roller 16 slowly extends downward, so that the protective curtain 14 that was originally in a retracted state can be unfolded downward together with the second pull rope 32 extending downward, and the first drive gear 10 and the second drive gear 11 of the transmission mechanism body are protected, so as to prevent the dust generated by the arc-shaped cleaning bucket 8 cleaning the track 6 from floating on the surface of the first drive gear 10 and the second drive gear 11, and affecting the transmission between the first drive gear 10 and the second drive gear 11, and also prevent the dust from affecting the lubrication effect of the automatic lubrication mechanism.

[0039] As a technical optimization solution of the present invention, an electric telescopic curtain 17 is installed at the bottom of the top plate 2, and the electric telescopic curtain 17 is located directly above the first drive motor 3. The first lubrication box 4 and the second lubrication box 5 are connected by a connecting pipe 9, and a valve is installed on the top of the connecting pipe 9. The electric telescopic curtain 17 installed at the bottom of the top plate 2 can be used in the cold winter when the transmission mechanism body is used. The transmission efficiency of the first drive motor 3 will be affected in an environment with relatively low temperature. The electric telescopic curtain 17 can be started by an external remote control, so that the electric telescopic curtain 17, which is originally in a contracted state, is unfolded downward to protect the first drive motor 3, so that the heat generated by the first drive motor 3 during operation will not be lost, and the temperature of the first drive motor 3 located inside the electric telescopic curtain 17 will rise, so that the transmission efficiency of the first drive motor 3 will not be affected, ensuring that the first drive motor 3 can operate normally in a low temperature environment; and in a low temperature environment, the lubricating oil stored in the first lubrication box 4 will be affected and become viscous, making the lubricating oil in the first lubrication box 4 The oil cannot be quickly replenished into the second lubrication box 5 through the connecting pipe 9. At this time, the heat generated by the operation of the first drive motor 3 covered by the electric telescopic curtain 17 will be guided by the top plate 2, so that this part of the heat can be absorbed by the first lubrication box 4, thereby increasing the temperature in the first lubrication box 4, reducing the viscosity of the lubricating oil stored in the first lubrication box 4 due to the influence of low temperature, and facilitating the automatic lubrication mechanism to apply the lubricating oil to the tooth surface of the first drive gear 10 under low temperature conditions; at the same time, in the process of the transmission mechanism body driving the truss 1 to rotate, the external environment suddenly produces rain or snow, and the electric telescopic curtain 17 can be controlled by the remote control again to expand downward to protect the first drive motor 3, so as to prevent the external rain from affecting the operation of the first drive motor 3.

[0040] In the present invention, after the first drive motor 3 is started, it can drive the first drive gear 10 to rotate, so that the second drive gear 11 meshing with the first drive gear 10 and the roller 7 rotate, and the roller 7 can drive the truss 1 and the rake frame to rotate in the concentration tank while moving in the track 6, so that the concentrated product in the concentration tank can be raked to the discharge port at the center of the tank bottom.

[0041] When the first drive motor 3 is started and drives the first drive gear 10 to rotate, it can synchronously drive the rotating block 31 on the outer wall of the output end of the first drive motor 3 to rotate, and through a series of structures, drive the push plate 27 to move upward in the second lubrication box 5 to push the lubricating oil stored in the second lubrication box 5 upward to the position of the guide pipe 20, so that the lubricating oil can enter the guide pipe 20 and flow downward to the oil drain port 24, and be discharged through the oil drain port 24 to the sponge block 22 for adsorption and storage. While the first drive gear 10 is rotating, the tooth surface of the first drive gear 10 can be squeezed with the sponge block 22, and the lubricating oil adsorbed and stored in the sponge block 22 is squeezed onto the tooth surface of the first drive gear 10, and it is automatically lubricated, without the need to manually apply the lubricating oil to the tooth surface of the first drive gear 10 multiple times, and there is no need to cut off the power to the entire transmission mechanism body during the work of applying the lubricating oil to the first drive gear 10, so as to avoid affecting the normal operation of the concentrator.

[0042] When there are debris in the track 6 that affects the movement of the roller 7 of the driving mechanism body, the second driving motor 12 can be started to drive the first winding roller 13 to rotate, so that the first pull rope 33 extends downward to drive the arc-shaped cleaning bucket 8 with one end of the counterweight block 35 to slowly rotate downward to the inside of the track 6 until it abuts against the inner bottom surface of the track 6. While the conveying mechanism body drives the truss 1 to rotate, the arc-shaped cleaning bucket 8 can also move synchronously in the track 6. While moving, it can automatically scrape the debris in the track 6, and automatically collect the cleaned debris on the top of the arc-shaped cleaning bucket 8. As more and more debris is cleaned and collected, the debris can be automatically discharged from the discharge hopper 37 to the outside of the track 6, so as to realize automatic cleaning of the debris in the track 6, thereby avoiding the debris from affecting the movement of the roller 7, and ensuring that the rotation of the truss 1 is not affected, thereby improving the working efficiency of the concentrator.

[0043] At the same time, when the arc-shaped cleaning bucket 8 cleans the debris in the track 6, a large amount of dust will float out from the track 6, and when the second drive motor 12 drives the first winding roller 13 to rotate, it can also synchronously drive the second winding roller 16, so that the second pull rope 32 wrapped around the outer wall of the second winding roller 16 slowly extends downward, so that the protective curtain 14 that was originally in a retracted state can be unfolded downward together with the second pull rope 32 extending downward, and the first drive gear 10 and the second drive gear 11 of the transmission mechanism body are protected, thereby preventing the dust generated by the arc-shaped cleaning bucket 8 cleaning the track 6 from scattering on the surface of the first drive gear 10 and the second drive gear 11, affecting the transmission between the first drive gear 10 and the second drive gear 11, and also preventing the dust from affecting the lubrication effect of the automatic lubrication mechanism.
