DETAILED DESCRIPTION

[0043] The content of the application will be described in detail below in combination with the drawings and examples of the specification:

[0044] As Figures 1 to 15 shown, an integrated hydraulic cylinder with a protection and adjustment mechanism comprises a cylinder body, which comprises a top cover 10, a bottom cover 11, a cylinder body 12, a piston rod 13 and a piston 14. The top cover 10 and the bottom cover 11 are respectively arranged at two ends of the cylinder body 12. The piston rod 13 is arranged into the cylinder body 12 through the top cover 10. The piston 14 is arranged inside the cylinder body 12. The piston rod 13 is fixedly connected with the piston 14.

[0045] It further comprises a cleaning mechanism and a spraying mechanism.

[0046] The cleaning mechanism is arranged on the top of the top cover 10, and the cleaning mechanism comprises a scraper 15, a rotating ring 16, an extension assembly and a driving assembly; the top of the top cover 10 is further fixedly provided with an annular support plate 17, the rotating ring 16 is located in the annular support plate 17, and a bearing 18 is arranged between the rotating ring 16 and the annular support plate 17, so that the rotating ring 16 rotates in the annular support plate 17; the driving assembly is installed on the top cover 10 and drives the rotating ring 16 to rotate, the extension assembly is installed on the rotating ring 16, and the scraper 15 is arranged at the end of the extension assembly;

[0047] The spraying mechanism is arranged on the top of the top cover 10, and the spraying mechanism comprises a receiving pipe 19, an oil storage box 20, a transmission assembly, an extrusion assembly, a conveying assembly and a plurality of atomizing nozzles 21; the oil storage box 20 is fixedly arranged on the top of the top cover 10 through a mounting plate, the receiving pipe 19 is installed at the bottom of the oil storage box 20 and connected with the oil storage box 20 through an oil outlet pipe 22, the conveying assembly is arranged on the top of the top cover 10, the receiving pipe 19 is fixedly connected with the mounting plate, the plurality of atomizing nozzles 21 are arranged at equal intervals on the conveying assembly, the extrusion assembly is inserted on the receiving pipe 19, and the transmission assembly is arranged between the driving assembly and the extrusion assembly.

[0048] As shown in Figure 1 , 2 , 4, 7, 12, 14, the driving assembly comprises a motor 23 and a driving gear 24; the motor 23 is fixedly arranged on the top of the top cover 10 through an L-shaped plate, and the driving gear 24 is fixedly arranged on the output end thereof; a gear ring 25 is further installed on the rotating ring 16, and the gear ring 25 is in meshing connection with the driving gear 24.

[0049] A dustproof ring 36 is installed on the middle part of the top cover 10, the dustproof ring 36 is sleeved on the outer periphery of the piston rod 13, is used for plugging the gap between the outer wall of the piston rod 13 and the top cover 10, and is used for isolating dust and impurities in the external air outside the cylinder body 12, so as to prevent the dust and impurities from entering the inside of the cylinder body 12 and causing abrasion of the piston 14 and the piston rod 13.

[0050] When the scraper 15 descends until the top of the dustproof ring 36 is attached, the motor 23 is started through the microcontroller, so that the driving gear 24 on the output end thereof rotates; since the gear ring 25 is in rotating connection with the annular support plate 17 through the rotating ring 16 and the bearing 18, and the gear ring 25 is in meshing connection with the driving gear 24, the gear ring 25 rotates; since the scraper 15 is arranged on the gear ring 25 through the extension assembly, the scraper 15 is further driven to rotate one circle around the piston rod 13, and the dust and impurities accumulated on the top of the dustproof ring 36 are concentrated on the position where the dustproof ring 36 on the top is aligned with the scraper 47; then the output end of the first micro electric push rod 26 is retracted through the microcontroller, so as to drive the scraper 15 to reset, that is, to drive the scraper 15 to rise, so as to prevent the scraper 47 from being in contact with the scraper 47 which is about to extend to shovel away the dust and impurities.

[0051] Referring to Figure 7, 9 As shown, the telescopic assembly includes a first miniature electric push rod 26, a slider 27, a guide rail 28, a sliding rod 29, a telescopic spring 30, and a mounting block 31. The guide rail 28 is fixedly installed on the side wall of the toothed ring 25 of the rotating ring 16. The slider 27 is slidably embedded in the guide rail 28. The first miniature electric push rod 26 is fixedly installed on the top of the guide rail 28, and the output end of the first miniature electric push rod 26 is fixedly connected to the top of the slider 27. The sliding rod 29 and the slider 27 are telescopically connected. The mounting block 31 is fixedly installed on the bottom end of the sliding rod 29. The telescopic spring 30 is sleeved on the outer periphery of the sliding rod 29, and both ends of the telescopic spring 30 abut against the slider 27 and the mounting block 31, respectively. One end of the scraper 15 is hinged to the mounting block 31.

[0052] The piston rod 13 of the existing hydraulic cylinder is exposed to outside air during operation, making it prone to the adhesion of dust and impurities. Each time the piston rod 13 retracts into the cylinder body 12, the dust and other impurities adhering to its outer wall tend to accumulate on the top of the dustproof ring 36. When the accumulation reaches a certain level, it can easily cause scratches on the outer wall of the piston rod 13. These scratches can also damage the dustproof ring 36, allowing dust and impurities to enter the cylinder body 12 and damage the piston 14, causing hydraulic oil leakage and reducing the service life of the hydraulic cylinder. At the same time, it will also reduce the working efficiency of the piston rod 13, thereby reducing the working efficiency of the hydraulic cylinder. This hydraulic cylinder is equipped with a micro controller. All electrical devices designed on this hydraulic cylinder are electrically connected to the micro controller. When a large amount of dust and impurities accumulate on the top of the dustproof ring 36, the controller activates the first micro electric push rod 26. Initially, the telescopic spring 30 is in a taut state. When the output end of the first micro electric push rod 26 drives the slider 27 to extend towards the end near the piston rod 13, the insert rod 35 slides from top to bottom inside the slide groove 34. Since the slide rod 29 is slidably connected to the slider 27, the telescopic spring 30 is sleeved with the slide rod 29. The bottom of the slider 27 and the top of the mounting block 31 respectively abut against the two ends of the telescopic spring 30, thereby causing the telescopic spring 30 to change from a taut state to a stretched state. Thus, when the slider 27 slides into place, the mounting block 31 drives the scraper 15 to descend until it is in contact with the top of the dustproof ring 36.

[0053] like Figure 14 As shown, a limiting plate 33 is fixedly provided at the bottom of the guide rail 28. A sliding groove 34 is obliquely opened on the limiting plate 33. An insert rod 35 is fixed on the mounting block 31, and the insert rod 35 extends into the sliding groove 34 and moves back and forth in the sliding groove 34.

[0054] When the slider 27 slides transversely on the outer wall of the guide rail 28, the insertion rod 35 will reciprocate in the interior of the sliding groove 34, so that the mounting block 31 is obliquely lifted under the cooperation of the sliding rod 29 and the expansion spring 30, so as to realize the oblique lifting of the scraper 15 through the mounting block 31. On the one hand, the scraper 15 is facilitated to extend to the top of the dustproof ring 36, and the dust and impurities accumulated on the top of the dustproof ring 36 are scraped to a centralized position in time. On the other hand, the scraper 15 is facilitated to retract from the accumulation position and avoid the approaching shovel plate 47.

[0055] As shown in Figure 5 , the transmission assembly includes a driven gear 37, a rotating shaft 38 and a pad 39. The pad 39 is fixedly arranged on the top of the top cover 10, the rotating shaft 38 is rotatably arranged on the top of the pad 39, and the driven gear 37 is fixedly sleeved on the outer wall of the rotating shaft 38. The driven gear 37 is in meshing connection with the gear ring 25. When the gear ring 25 drives the scraper 15 to rotate and flatly scrape the dust and impurities accumulated on the top of the dustproof ring 36, the driven gear 37 is in meshing connection with the gear ring 25, the driven gear 37 is fixedly connected with the rotating shaft 38, the rotating shaft 38 is rotatably connected with the pad 39, and the pad 39 is fixedly connected with the top of the top cover 10, thereby driving the driven gear 37 to rotate.

[0056] As shown in Figure 5 , 6 , the extrusion assembly includes a rotating disc 40, a connecting rod 41, a sliding bar 42, an extrusion rod 43 and a sliding rail 44. The rotating disc 40 is coaxially connected to the top end of the rotating shaft 38. The top of the top cover 10 is fixedly provided with a mounting table, and the sliding rail 44 is fixedly arranged on the top of the mounting table. The sliding bar 42 is slidingly installed in the sliding rail 44. The connecting rod 41 is hingedly connected to the rotating disc 40 and one end of the sliding bar 42. The extrusion rod 43 is installed on the other end of the sliding bar 42. The extrusion rod 43 extends into the receiving pipe 19. The receiving pipe 19 is provided with an arc-shaped baffle 45 connected with the extrusion rod 43. The receiving pipe 19 is also provided with an oil outlet.

[0057] When the driven gear 37 rotates, since the rotating shaft 38 is fixedly connected with the rotating disc 40, the sliding bar 42 is slidingly connected with the sliding rail 44, the rotating disc 40 and the sliding bar 42 are respectively hinged with the two ends of the connecting rod 41, one end of the extrusion rod 43 is fixedly connected with the sliding bar 42, and the other end of the extrusion rod 43 is inserted with the receiving pipe 19, so that the extrusion rod 43 slides in the inside of the receiving pipe 19 to the end close to the oil outlet, and the lubricating oil previously flowing into the receiving pipe 19 from the oil outlet pipe 22 and the oil receiving port is extruded to the delivery pipe 49. It should be noted that the arc-shaped baffle 45 blocks the oil receiving port each time the extrusion rod 43 slides in the inside of the receiving pipe 19 to the end close to the oil outlet, so as to prevent the lubricating oil in the oil storage box 20 from falling between the extrusion rod 43 and the inside end of the receiving pipe 19 close to the sliding rail 44. When the extrusion rod 43 resets to the initial state each time, the arc-shaped baffle 45 moves away from below the oil receiving port, so as to facilitate the lubricating oil in the oil storage box 20 to automatically flow into the inside of the receiving pipe 19 through the oil outlet pipe 22, to realize automatic filling, and to prepare for the next time for the piston rod 13 to spray lubricating oil.

[0058] As shown in Figure 6 , 7 , 10, 11, 13, the delivery assembly comprises a delivery pipe 49, an annular pipe 50 and a plurality of branch pipes 51; the annular pipe 50 is fixedly arranged on the top of the top cover 10 through a plurality of support rods, and the plurality of branch pipes 51 are fixedly arranged on the annular pipe 50 and extend inwardly, and each of the branch pipes 51 is provided with an atomizing nozzle 21 at the inner end; the oil outlet of the receiving pipe 19 is connected with the annular pipe 50 through the delivery pipe 49; and the top of the oil storage box 20 is provided with an adding pipe 52, and the adding pipe 52 is provided with a sealing plug 53.

[0059] When the lubricating oil previously flowing into the receiving pipe 19 from the oil outlet pipe 22 and the oil receiving port is extruded into the inside of the delivery pipe 49, since the annular pipe 50 is fixedly connected with the top cover 10 through three support rods, the plurality of branch pipes 51 are fixedly connected with the annular pipe 50, and each of the branch pipes 51 is fixedly connected with an atomizing nozzle 21 at the end away from the annular pipe 50, and the end of the receiving pipe 19 close to the delivery pipe 49 is designed as an oil outlet, and the oil outlet and the annular pipe 50 are fixedly connected with the two ends of the delivery pipe 49, so that the lubricating oil is sprayed on the outer wall of the piston rod 13 in an atomized state, that is, the outer wall of the piston rod 13 is coated with lubricating oil, which can increase the contact friction between the piston rod 13 and the dustproof ring 36, reduce the abrasion, prevent the piston rod 13 from being eroded by oxides or acidic gases during work, increase the corrosion resistance, achieve the rust prevention effect, avoid the piston rod 13 from being broken during work, and two effects are beneficial to increase the fit between the parts of the oil cylinder, reduce the friction, reduce the abrasion, achieve the protection effect, and thus improve the hydraulic performance and service life of the hydraulic oil cylinder, and reduce the use cost.

[0060] As shown in Figure 15As shown, the outer wall of the top cover 10, the bottom cover 11 and the piston 14 is sleeved with a sealing ring, the outer wall of the one end of the cylinder body 12 close to the bottom cover 11 is fixedly provided with an oil inlet pipe 55, and the top cover 10 and the bottom cover 11 are each designed with a sealing ring, which is to prevent dust and impurities in the external air from entering the inside of the cylinder body 12 to cause abrasion of the internal parts of the cylinder body 12, the sealing ring designed on the outer wall of the piston 14 is to isolate the hydraulic oil and prevent the hydraulic oil from entering the rod cavity from the rodless cavity, which all play a sealing role, the oil inlet pipe 55 facilitates injection of hydraulic oil into the rodless cavity of the oil cylinder body 12, so as to realize pushing of the piston 14, and then pushing of the piston rod 13 through the piston 14.

[0061] As shown in Figure 3 , 7 , the top of the top cover 10 is fixedly provided with a second micro electric push rod 46, the output end of which is fixedly provided with a shovel plate 47, and the outer wall of the annular support plate 17 is provided with an avoiding gap 48 for the shovel plate 47 to extend out, in the initial state, the bottom of the shovel plate 47 is attached to the top of the top cover 10, when the scraper 15 rises, the second micro electric push rod 46 is started through the controller, so that the output end thereof extends to the dust and impurities accumulated near the top of the dustproof ring 36, since the output end is fixedly connected with the shovel plate 47, the output end drives the shovel plate 47 to extend to the dust and impurities accumulated near the top of the dustproof ring 36, and then the dust and impurities accumulated on the top of the dustproof ring 36 are shoveled through the avoiding gap 48 and discharged from the inner ring of the annular support plate 17, so as to facilitate the user to clean in time, so as to improve the working efficiency of the hydraulic oil cylinder.

[0062] The working principle of the present application: the existing hydraulic cylinder piston rod 13 is easy to stick dust and impurities due to contact with the outside air during work, and the dust and impurities adhered to the outer wall of the piston rod 13 are easy to accumulate on the top of the dustproof ring 36 every time the piston rod 13 retracts into the cylinder body 12. When the accumulated amount reaches a certain degree, not only is the piston rod 13 easy to scratch, but these scratches can also cause damage to the dustproof ring 36, allowing dust and impurities to enter the cylinder body 12 and damage the piston 14, causing hydraulic oil leakage and reducing the service life of the hydraulic cylinder. At the same time, it also reduces the working efficiency of the piston rod 13, thereby reducing the working efficiency of the oil cylinder. The oil cylinder is equipped with a microcontroller, and each electrical device designed on the hydraulic cylinder is electrically connected to the microcontroller. When the dust and impurities accumulated on the top of the dustproof ring 36 are more each time, the first micro electric push rod 26 is started through the controller. In the initial state, the extension spring 30 is in a tight state. When the output end of the first micro electric push rod 26 drives the sliding block 27 to extend towards the end of the piston rod 13, the plug rod 35 slides inside the sliding groove 34 from top to bottom. Since the sliding rod 29 is slidingly connected to the sliding block 27, the extension spring 30 is sleeved with the sliding rod 29, and the bottom of the sliding block 27 and the top of the mounting block 31 are respectively in contact with the two ends of the extension spring 30, thereby causing the extension spring 30 to change from a tight state to a stretched state, so that when the sliding block 27 slides into place, the scraper 15 is lowered by the mounting block 31 until it is in contact with the top of the dustproof ring 36.

[0063] When the scraper 15 is lowered until it is in contact with the top of the dustproof ring 36, the motor 23 is started through the microcontroller, thereby causing the driving gear 24 on the output end to rotate. Since the gear ring 25 is rotatably connected to the annular support plate 17 through the rotating ring 16 and the bearing 18, the gear ring 25 is meshingly connected to the driving gear 24, thereby causing the gear ring 25 to rotate. Since the scraper 15 is designed on the gear ring 25 through the extension assembly, the scraper 15 is further driven to rotate one revolution around the piston rod 13, thereby concentrating the dust and impurities accumulated on the top of the dustproof ring 36 at a position aligned with the shovel plate 47 on the top of the dustproof ring 36. Then the output end of the first micro electric push rod 26 is retracted through the microcontroller, thereby resetting the scraper 15, i.e. driving the scraper 15 to rise, preventing the scraper 15 from being in contact with the shovel plate 47 which is about to extend to shovel away the dust and impurities.

[0064] In the initial state, the bottom of the shovel plate 47 is in contact with the top of the top cover 10. When the scraper 15 rises, the second micro electric push rod 46 is started through the controller, thereby causing the output end to extend towards the dust and impurities accumulated on the top of the dustproof ring 36. Since the output end is fixedly connected to the shovel plate 47, the output end drives the shovel plate 47 to extend towards the dust and impurities accumulated on the top of the dustproof ring 36, thereby shoveling the dust and impurities accumulated on the top of the dustproof ring 36 through the avoidance notch 48 and discharging them from the inner ring of the annular support plate 17, to facilitate timely cleaning by the user.

[0065] When the gear ring 25 drives the scraper 15 to rotate and scrape the dust and impurities accumulated on the top of the dustproof ring 36, the gear ring 25 is connected with the driven gear 37 in meshing, the driven gear 37 is fixedly connected with the rotating shaft 38, the rotating shaft 38 is rotatably connected with the pad 39, and the pad 39 is fixedly connected with the top of the top cover 10, thereby driving the driven gear 37 to rotate.

[0066] When the driven gear 37 rotates, the rotating disc 40 is fixedly connected with the rotating shaft 38, the sliding bar 42 is slidably connected with the sliding rail 44, the rotating disc 40 and the sliding bar 42 are respectively hinged with two ends of the connecting rod 41, one end of the extrusion rod 43 is fixedly connected with the sliding bar 42, the other end of the extrusion rod 43 is inserted with the receiving pipe 19, thereby making the extrusion rod 43 slide in the inside of the receiving pipe 19 to the end close to the oil outlet, extruding the lubricating oil previously flowed into the receiving pipe 19 from the oil outlet pipe 22 and the oil inlet into the conveying pipe 49, and it should be noted that the arc-shaped baffle 45 blocks the oil inlet each time the extrusion rod 43 slides in the inside of the receiving pipe 19 to the end close to the oil outlet, preventing the lubricating oil in the oil storage box 20 from falling between the extrusion rod 43 and the inside end of the receiving pipe 19 close to the sliding rail 44, and the arc-shaped baffle 45 moves away from below the oil inlet each time the extrusion rod 43 resets to the initial state, facilitating the lubricating oil in the oil storage box 20 to automatically flow into the inside of the receiving pipe 19 through the oil outlet pipe 22, realizing automatic filling, and preparing for the next time for the piston rod 13 to spray lubricating oil.

[0067] When the lubricating oil previously flowed into the receiving pipe 19 from the oil outlet pipe 22 and the oil inlet is extruded into the inside of the conveying pipe 49, since the annular pipe 50 is fixedly connected with the top cover 10 through three supporting rods, a plurality of branch pipes 51 are fixedly connected with the annular pipe 50, one end of each branch pipe 51 away from the annular pipe 50 is fixedly connected with one atomizing nozzle 21, the end of the receiving pipe 19 close to the conveying pipe 49 is designed with an oil outlet, and the oil outlet and the annular pipe 50 are respectively fixedly connected with two ends of the conveying pipe 49, thereby making the lubricating oil sprayed on the outer wall of the piston rod 13 in the circumferential direction in an atomized state, i.e. coating the outer wall of the piston rod 13 with lubricating oil, which on the one hand can increase the contact friction between the piston rod 13 and the dustproof ring 36, reduce wear, and on the other hand can prevent the piston rod 13 from being eroded by oxides or acidic gases during work, increase corrosion resistance, thereby achieving the effect of preventing rust, avoiding the piston rod 13 from being broken during work, and both effects are conducive to increasing the fit between the parts of the oil cylinder, reducing friction, reducing wear, playing a protective effect, thereby improving the hydraulic performance and service life of the hydraulic oil cylinder, and reducing the use cost.

[0068] The top cover 10 and the bottom cover 11 are respectively provided with a sealing ring, which is used to prevent dust and impurities in the outside air from entering the inside of the cylinder body 12 to cause abrasion of the internal parts of the cylinder body 12. The sealing ring designed on the outer wall of the piston 14 is used to isolate the hydraulic oil and prevent the hydraulic oil from entering the rod cavity from the rodless cavity, and both of them play a sealing role.
