Description

Technical Field

[0001] This invention belongs to the field of hydraulic breaker technology, specifically a cylinder component of a hydraulic breaker. Background Technology

[0002] A hydraulic breaker is an engineering tool that uses a hydraulic system as a power source to convert hydraulic energy into high-frequency, high-intensity mechanical impact energy for breaking hard objects such as rocks and concrete. The cylinder is the most crucial working component of a hydraulic breaker. Its function is similar to that of an engine cylinder; it is the key part that converts hydraulic energy into impact mechanical energy.

[0003] Patent CN216589387U discloses a cylinder assembly for a hydraulic breaker, belonging to the field of breaker technology. It solves the technical problems of cylinder scoring in existing hydraulic breakers. This hydraulic breaker cylinder assembly includes a cylinder body and a piston. The piston is installed in a piston bore and can move axially up and down relative to the cylinder body. The piston includes a piston part and a piston part, with a stepped surface at the connection between the piston part and piston part. A working chamber is formed between the inner wall of the cylinder body and the outer peripheral surface of the piston part. A protective groove is provided on the inner wall of the cylinder body. When the piston strikes the chisel, the protective groove and the working chamber communicate, and the stepped surface is located at the opening of the protective groove. This patent can prevent cylinder scoring.

However, during this process, friction exists between the chisel and the guide components inside the cylinder, which easily causes wear and affects the service life of the parts. To solve this problem, manual lubrication is usually performed at regular intervals, but this increases the labor intensity of the operators. Summary of the Invention

[0009] Preferably, an oil injection pipe is inserted into one side of the lower end of the cylinder block, and an oil injection nozzle is provided at one end of the oil injection pipe. A sleeve is fixedly connected to one side of the upper end of the inner cavity of the oil storage block. A sealing rod is slidably connected to the inner cavity of the sleeve. The sealing rod is inserted into and slidably connected to one side of the oil storage block. A spring is fixedly connected to one end of the sealing rod, and the other end of the spring is fixedly connected to one end of the inner cavity of the sleeve.

[0011] Preferably, a second sleeve is slidably connected to one side of the vibrating rod, the upper end of the second sleeve is fixedly connected to the oil storage block, a spring damper is fixedly connected to one side of the upper end of the inner cavity of the oil storage block, the spring damper is located in the inner cavity of the second sleeve, and the piston end of the spring damper is fixedly connected to one end of the vibrating rod.

[0012] Preferably, it also includes an anti-clogging filter component; The anti-clogging filter assembly includes multiple rotating rods evenly distributed around the circumference of the turntable. One end of each rotating rod is fixedly connected to the turntable, and the other end is fixedly connected to a scraper.

[0016] The beneficial effects of this invention are as follows: 1. The hydraulic breaker cylinder component of this invention utilizes an elastic potential energy lubrication system. Whenever the chisel vibrates, a certain amount of lubricating oil flows between the chisel and the wear-resistant sleeve, thereby reducing wear between the chisel and the wear-resistant sleeve and improving the service life of the equipment. Furthermore, the entire lubrication process utilizes elastic potential energy, eliminating the need for manual lubrication by workers, thus reducing their workload.

[0017] 2. The hydraulic breaker cylinder component of this invention utilizes an anti-clogging filter assembly. When lubricating oil flows out through the oil outlet, the filter screen intercepts impurities in the lubricating oil, effectively preventing impurities from flowing with the lubricating oil between the wear-resistant sleeve and the chisel, thus avoiding chisel jamming and accelerated wear on the chisel and wear-resistant sleeve. Furthermore, each time lubricating oil flows out through the oil outlet, each scraper grazes along the surface of a filter screen, scraping impurities adhering to the filter screen elsewhere, preventing impurities from clogging the filter screen. This ensures smooth flow of subsequent lubricating oil and avoids the situation where impurities become stuck between the sealing plate and the filter screen, preventing the sealing plate from failing to seal the oil outlet. Even if impurities remain inside the oil reservoir, operators can maintain cleanliness by periodically cleaning the inside of the oil reservoir. Attached Figure Description

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1-10 The present invention provides a technical solution: a hydraulic breaker cylinder component, including a cylinder body 1 and a chisel 9, the chisel 9 being located in the inner cavity of the cylinder body 1, a wear-resistant sleeve 33 being fixedly connected to one side of the bottom of the inner cavity of the cylinder body 1, the wear-resistant sleeve 33 being slidably connected to the chisel 9, a piston rod 6 being slidably arranged in the inner cavity of the cylinder body 1, an upper oil chamber 11 and a lower oil chamber 7 being respectively arranged on the upper and lower sides of the inner cavity of the cylinder body 1, and a reversing valve 3 being fixedly connected to one side of the outer wall of the cylinder body 1; It also includes elastic potential energy lubrication components; The elastic potential energy lubrication assembly includes an oil storage block 34 fixedly connected to the upper end of the drill rod 9. The lower side of the oil storage block 34 has a plurality of oil outlet grids 13 evenly distributed along the circumference. The lower end face of the inner cavity of the oil storage block 34 has a plurality of sealing plates 15 evenly distributed and slidably arranged along the circumference, and each sealing plate 15 corresponds to an oil outlet grid 13.

[0023] In this embodiment, as Figures 2-10 As shown, a nitrogen chamber 2 is fixedly connected to the upper end of the middle cylinder 1, and one end of the piston rod 6 is located in the inner cavity of the nitrogen chamber 2.

[0024] A reversing valve 3 is fixedly connected to one side of the outer wall of the middle cylinder 1. The reversing valve 3 has an oil inlet 4 and an oil outlet 5 on one side, and an oil port 1 8 and an oil port 2 12 on the other side. The oil port 1 8 is connected to the lower oil chamber 7, and the oil port 2 12 is connected to the upper oil chamber 11.

[0025] An oil injection pipe 10 is inserted into one side of the lower end of the cylinder block 1. An oil injection nozzle 17 is provided at one end of the oil injection pipe 10. A sleeve 19 is fixedly connected to one side of the upper end of the inner cavity of the oil storage block 34. A sealing rod 18 is slidably connected to the inner cavity of the sleeve 19. The sealing rod 18 is inserted into and slidably connected to one side of the oil storage block 34. A spring 20 is fixedly connected to one end of the sealing rod 18. The other end of the spring 20 is fixedly connected to one end of the inner cavity of the sleeve 19.

[0026] A housing 21 is fixedly connected to one side of the upper end face of the inner cavity of the oil storage block 34. A turntable 25 is rotatably arranged on one side of the bottom of the housing 21. A vibration rod 24 is slidably connected to the middle of the turntable 25. Multiple connecting rods 26 are evenly distributed and rotatably arranged along the circumference at the lower end of the vibration rod 24, and one end of each connecting rod 26 is rotatably connected to a sealing plate 15.

[0027] A sleeve 23 is slidably connected to one side of the vibrating rod 24. The upper end of the sleeve 23 is fixedly connected to the oil storage block 34. A spring damper 22 is fixedly connected to one side of the upper end of the inner cavity of the oil storage block 34. The spring damper 22 is located in the inner cavity of the sleeve 23. The piston end of the spring damper 22 is fixedly connected to one end of the vibrating rod 24.

[0028] Specifically, in existing technology, oil is supplied to the inner cavity of the cylinder 1 and its flow direction is controlled to drive the piston rod 6 to reciprocate and strike the chisel 9, thereby achieving the crushing function. However, during this process, there is friction between the chisel 9 and the guide components inside the cylinder 1, which easily causes wear on the components and affects their service life. To solve this problem, manual lubrication is usually added at regular intervals, but this increases the labor intensity of the operators.

[0029] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: First, the middle cylinder 1 is fixedly installed in a suitable position on the hydraulic breaker. Then, the oil injection pipe 10 is pushed to slide on the middle cylinder 1, and the end of the oil injection pipe 10 is used to squeeze the sealing rod 18, causing the sealing rod 18 to retract into the inner cavity of the oil storage block 34 until the oil injection nozzle 17 extends into the inner cavity of the oil storage block 34. Then, an appropriate amount of lubricating oil is added through the oil injection pipe 10, and the lubricating oil is injected into the inner cavity of the oil storage block 34 through the oil injection nozzle 17. After the lubricating oil is added, the oil injection pipe 10 is removed from the inner cavity of the oil storage block 34, and the sealing rod 18 is reset under the action of the spring 20, sealing one side of the oil storage block 34. In addition, the multiple sealing plates 15 in the initial state seal each oil outlet 13, so lubricating oil will not flow out through the oil outlet 13.

[0030] The chisel 9 is brought into contact with the object to be broken, and nitrogen is added to the nitrogen chamber 2 through the air inlet. Then, the hydraulic oil entering the lower oil chamber 7 and upper oil chamber 11 is controlled by the reversing valve 3, oil inlet 4, and oil outlet 5. Simultaneously, the nitrogen compresses the piston rod 6, thus achieving the reciprocating motion of the piston rod 6. This motion method is existing technology, and how the flow of hydraulic oil is controlled is common knowledge to those skilled in the art, and will not be elaborated further here. When the piston rod 6 reciprocates, it pushes the chisel 9 back and forth, using the chisel 9 to break the object. Each time the piston rod 6 completes its impact and retracts, the chisel 9, under the combined action of its own inertia and the object's reaction force, naturally falls back to the waiting position within the constraint range of the wear-resistant sleeve 33, awaiting the next impact of the piston rod 6. This reset method is also common knowledge to those skilled in the art, and will not be elaborated further here. When the drill rod 9 vibrates up and down, the vibrating rod 24 moves up and down due to inertia. When the vibrating rod 24 moves upward, it drives multiple sealing plates 15 to slide at the bottom of the oil storage block 34 and away from the oil outlet 13 through multiple connecting rods 26. The lubricating oil in the oil storage block 34 then flows through the oil outlet 13 into the space between the drill rod 9 and the wear-resistant sleeve 33, lubricating both. Subsequently, the vibrating rod 24 returns to its original position under the action of the spring damper 22, and the multiple sealing plates 15 seal the oil outlet 13 again. This cycle repeats, ensuring that a certain amount of lubricating oil flows into the space between the drill rod 9 and the wear-resistant sleeve 33 whenever the drill rod 9 vibrates, thereby reducing wear on both the drill rod 9 and the wear-resistant sleeve 33 and improving the service life of the equipment. In addition, the entire lubrication process utilizes elastic potential energy, eliminating the need for manual addition of lubricating oil by workers, thus reducing the labor intensity of workers.

[0031] In this embodiment, as Figure 6 , Figure 7 , Figure 10 As shown, it also includes an anti-clogging filter component; The anti-clogging filter assembly includes multiple rotating rods 16 evenly distributed around the circumference of the turntable 25. One end of the rotating rod 16 is fixedly connected to the turntable 25, and the other end is fixedly connected to a scraper 32. One edge of the scraper 32 is in contact with the inner wall of the oil storage block 34. A connecting rod 28 is fixedly connected to one side of the vibrating rod 24.

[0032] A filter screen 14 is fixedly connected to one side of the oil outlet 13.

[0033] A bevel gear 27 is fixedly mounted on the upper end of the turntable 25. A bevel gear 31 and a gear 30 are rotatably mounted on one side of the upper end of the inner cavity of the oil storage block 34. The bevel gear 31 and the gear 30 are fixedly connected, and the bevel gear 27 and the bevel gear 31 mesh with each other.

[0034] A rack 29 is fixedly connected to one end of the connecting rod 28, and the rack 29 meshes with the gear 30.

[0035] Specifically, in the above embodiment, although the oil reservoir 34 can be used to store lubricating oil and intermittently added between the wear-resistant sleeve 33 and the drill rod 9, the added lubricating oil may accidentally contain metal particle impurities. If these impurities flow with the lubricating oil between the wear-resistant sleeve 33 and the drill rod 9, they may not only easily cause the drill rod 9 to jam, but may also aggravate the wear of the drill rod 9 and the wear-resistant sleeve 33. In addition, as the drill rod 9 is frequently impacted, the inner wall of the oil reservoir 34 may peel off, and the resulting metal debris will also flow with the lubricating oil through the oil outlet 13 between the wear-resistant sleeve 33 and the drill rod 9, which will also face the above-mentioned problems.

[0036] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: By installing a filter screen 14 on one side of the oil outlet 13, the filter screen 14 intercepts impurities in the lubricating oil as it flows out of the oil outlet 13. This effectively prevents impurities from flowing with the lubricating oil between the wear-resistant sleeve 33 and the drill rod 9, thus avoiding jamming of the drill rod 9 and exacerbating the wear between the drill rod 9 and the wear-resistant sleeve 33. Although the filter screen 14 can filter out impurities in the lubricating oil, it can also easily become clogged when impurities adhere to it. This not only affects the subsequent flow of lubricating oil but may also prevent the sealing plate 15 from sealing the oil outlet 13 due to impurities getting stuck between it and the filter screen 14. Therefore, to avoid this situation, when the sealing plate 15 blocks the oil outlet 13, the scraper 32 is in contact with the inner wall of the oil storage block 34 and is not within the area of ​​the filter screen 14. When the sealing plate 15 moves away from the oil outlet filter 13, the vibrating rod 24 rises, causing the rack 29 to drive the gear 30 to rotate. This, in turn, causes the turntable 25 to rotate through the cooperation of bevel gear 27 and bevel gear 31. When the turntable 25 rotates, it drives multiple scrapers 32 to rotate simultaneously via the rotating rod 16. The scrapers 32 then slide across the surface of the filter screen 14, scraping away the impurities adhering to the surface of the filter screen 14. When the sealing plate 15 returns to its original position, the scrapers 32 move away from the filter screen 14 again, without affecting the resetting of the sealing plate 15. This cycle repeats. Whenever lubricating oil flows out through the oil outlet filter 13, each scraper 32 slides across the surface of a filter screen 14, scraping away the impurities adhering to the surface of the filter screen 14. This prevents impurities from clogging the filter screen 14, ensuring the smooth flow of subsequent lubricating oil and avoiding the situation where impurities get stuck between the sealing plate 15 and the filter screen 14, preventing the sealing plate 15 from blocking the oil outlet filter 13. Furthermore, even if impurities remain inside the oil storage block 34, operators can keep it clean by regularly cleaning the inside of the oil storage block 34.

[0037] Working principle: First, the middle cylinder 1 is fixedly installed in a suitable position on the hydraulic breaker. Then, the oil injection pipe 10 is pushed to slide on the middle cylinder 1, and the end of the oil injection pipe 10 squeezes the sealing rod 18, causing the sealing rod 18 to retract into the inner cavity of the oil storage block 34 until the oil injection nozzle 17 extends into the inner cavity of the oil storage block 34. Then, an appropriate amount of lubricating oil is added through the oil injection pipe 10, and the lubricating oil is injected into the inner cavity of the oil storage block 34 through the oil injection nozzle 17. After the lubricating oil is added, the oil injection pipe 10 is removed from the inner cavity of the oil storage block 34, and the sealing rod 18 is reset under the action of the spring 20, sealing one side of the oil storage block 34. In addition, the multiple sealing plates 15 in the initial state block each oil outlet 13, and the lubricating oil will not flow out through the oil outlet 13. The chisel 9 is brought into contact with the object to be broken, and nitrogen is added to the nitrogen chamber 2 through the air inlet. Then, the hydraulic oil entering the lower oil chamber 7 and upper oil chamber 11 is controlled by the reversing valve 3, oil inlet 4, and oil outlet 5. Simultaneously, the nitrogen compresses the piston rod 6, thus achieving the reciprocating motion of the piston rod 6. This motion method is existing technology, and how the flow of hydraulic oil is controlled is common knowledge to those skilled in the art, and will not be elaborated further here. When the piston rod 6 reciprocates, it pushes the chisel 9 back and forth, using the chisel 9 to break the object. Each time the piston rod 6 completes its impact and retracts, the chisel 9, under the combined action of its own inertia and the object's reaction force, naturally falls back to the waiting position within the constraint range of the wear-resistant sleeve 33, awaiting the next impact of the piston rod 6. This reset method is also common knowledge to those skilled in the art, and will not be elaborated further here. When the drill rod 9 vibrates up and down, the vibrating rod 24 moves up and down due to inertia. When the vibrating rod 24 moves upward, it drives multiple sealing plates 15 to slide at the bottom of the oil storage block 34 and away from the oil outlet 13 through multiple connecting rods 26. The lubricating oil in the oil storage block 34 then flows through the oil outlet 13 into the space between the drill rod 9 and the wear-resistant sleeve 33, lubricating both. Subsequently, the vibrating rod 24 returns to its original position under the action of the spring damper 22, and the multiple sealing plates 15 seal the oil outlet 13 again. This cycle repeats, ensuring that a certain amount of lubricating oil flows into the space between the drill rod 9 and the wear-resistant sleeve 33 whenever the drill rod 9 vibrates, thereby reducing wear on both the drill rod 9 and the wear-resistant sleeve 33 and improving the service life of the equipment. In addition, the entire lubrication process utilizes elastic potential energy, eliminating the need for manual addition of lubricating oil by workers, thus reducing the labor intensity of workers. By setting a filter screen 14 on one side of the oil outlet 13, when the lubricating oil flows out through the oil outlet 13, the filter screen 14 will intercept impurities in the lubricating oil, thereby effectively preventing impurities from flowing with the lubricating oil between the wear-resistant sleeve 33 and the drill rod 9, which would lead to the drill rod 9 getting stuck and aggravate the wear of the drill rod 9 and the wear-resistant sleeve 33.Although filter screen 14 can filter out impurities in lubricating oil, it can also easily become clogged when impurities adhere to it. This not only affects the flow of lubricating oil but may also prevent the sealing plate 15 from sealing the oil outlet filter 13 because impurities are stuck between the sealing plate 15 and the filter screen 14. Therefore, to avoid this situation, when the sealing plate 15 blocks the oil outlet filter 13, the scraper 32 is in contact with the inner wall of the oil reservoir 34 and is not within the area of ​​the filter screen 14. When the sealing plate 15 moves away from the oil outlet filter 13, the vibrating rod 24 rises, causing the rack 29 to drive the gear 30 to rotate. This, in turn, causes the turntable 25 to rotate through the cooperation of bevel gear 27 and bevel gear 31. When the turntable 25 rotates, it drives multiple scrapers 32 to rotate simultaneously via the rotating rod 16. The scrapers 32 then slide across the surface of the filter screen 14, scraping away the impurities adhering to the surface of the filter screen 14. When the sealing plate 15 returns to its original position, the scrapers 32 move away from the filter screen 14 again, without affecting the resetting of the sealing plate 15. This cycle repeats. Whenever lubricating oil flows out through the oil outlet filter 13, each scraper 32 slides across the surface of a filter screen 14, scraping away the impurities adhering to the surface of the filter screen 14. This prevents impurities from clogging the filter screen 14, ensuring the smooth flow of subsequent lubricating oil and avoiding the situation where impurities get stuck between the sealing plate 15 and the filter screen 14, preventing the sealing plate 15 from blocking the oil outlet filter 13. Furthermore, even if impurities remain inside the oil storage block 34, operators can keep it clean by regularly cleaning the inside of the oil storage block 34.
