Description

Technical Field

[0001] This application relates to the technical field of hydraulic breakers, and in particular to a triangular hydraulic breaker. Background Technology

[0002] Currently, in the field of construction machinery, hydraulic breakers are widely used as a highly efficient breaking tool in various industries such as building demolition, mining, and road construction. The power of a hydraulic breaker comes from the pressure provided by an excavator, loader, or pump station. The hydraulic static pressure drives the piston to reciprocate. During the piston's stroke, it strikes the chisel at high speed, transferring energy to the chisel, which then breaks solids such as ore, concrete, and rock. This allows for more efficient breaking operations and improves construction efficiency.

[0003] Regarding the aforementioned technologies: After prolonged use, the drill rod will experience wear and damage, requiring replacement. Replacing the drill rod necessitates the removal and reinstallation of multiple components, such as the locking nut of the drill rod holder and the drill sleeve. This process is cumbersome, resulting in low drill rod replacement efficiency. Summary of the Invention

[0004] To improve the efficiency of chisel replacement, this application provides a triangular hydraulic breaker.

[0005] This application provides a triangular hydraulic breaker, which adopts the following technical solution: A triangular hydraulic breaker, comprising: A hydraulic hammer body, wherein a movable groove is provided on the hydraulic hammer body; The movable mechanism includes a fixed component and a movable component, wherein the movable component is slidably disposed within the movable groove, and the fixed component is disposed between the movable component and the hydraulic hammer body; A chisel is detachably connected to the movable component, with one end of the chisel extending into the movable slot. When the movable component is inserted into the movable slot, the chisel can drive the fixing component to fix the movable component to the hydraulic hammer body.

[0006] By adopting the above technical solution, when the movable component is inserted into the movable slot, the chisel can drive the fixing component to secure the movable component to the hydraulic hammer body. This not only simplifies the chisel replacement process and improves replacement efficiency, but also ensures a stable connection between the movable component and the hydraulic hammer body under high-intensity working conditions, effectively avoiding safety hazards caused by loosening. Simultaneously, because the movable component can slide within the movable slot, the loading and unloading of the chisel is more convenient, reducing operation time and labor intensity, further improving the overall working efficiency of the equipment.

[0007] Optionally, the movable component includes a support base and a movable plate. One end of the support base is slidably connected to the inner wall of the movable groove, and the other end of the support base extends out of the movable groove. The fixing component is connected to the support base and the movable plate respectively. The movable plate is movably connected to the support base. A receiving groove is formed between the movable plate and the support base. The drill rod is inserted into the receiving groove and abuts against the fixing component. When the movable plate disengages from the movable groove, the movable plate can move away from the support base to open the receiving groove.

[0008] By adopting the above technical solution, when the drill rod needs to be replaced, the support base and movable plate are first slid out of the movable slot, and then the movable plate is moved away from the support base, thereby easily opening the receiving slot. This allows for direct removal of the old drill rod and insertion of the new drill rod without disassembling multiple parts, greatly simplifying the replacement process and improving the efficiency of drill rod replacement.

[0009] Optionally, the fixing component includes a fixing block, and the support base and the movable plate are respectively provided with sliding grooves. The sliding grooves are connected to the receiving groove. The fixing block is slidably inserted into the sliding groove. The inner wall of the movable groove is provided with a plug-in groove. When the drill rod is inserted into the receiving groove, the rotation of the drill rod can drive the fixing block to be inserted into the plug-in groove.

[0010] By adopting the above technical solution, once the drill rod is inserted into the receiving groove, and the support base and movable plate drive the drill rod into the movable groove, the fixed block can be moved along the slide groove and inserted into the insertion groove by rotating the drill rod, thereby achieving a stable connection between the movable component and the hydraulic hammer body. This design not only simplifies the installation process of the drill rod but also improves the efficiency and convenience of drill rod replacement. Furthermore, because the fixed block can slide within the slide groove, the entire structure is more flexible and reliable, avoiding safety hazards caused by insecure fixing.

[0011] Optionally, the fixing component includes a reset member disposed within the slide groove, the reset member being used to drive the fixing block to move into the receiving groove.

[0012] By adopting the above technical solution, the reset component is set in the slide groove, which can drive the fixed block to move into the receiving groove, so that the fixed block no longer limits the moving component, thereby simplifying the separation steps between the moving component and the hydraulic hammer body and improving work efficiency.

[0013] Optionally, the fixing block is provided with a first guide surface at one end near the receiving groove, the drill rod is provided with a connecting block, the connecting block is provided with a clearance groove, the inner wall of the clearance groove is provided with a second guide surface, the fixing block can be inserted into the clearance groove, and the drill rod can drive the fixing block to move into the insertion groove through the connecting block.

[0014] By adopting the above technical solution, one end of the fixing block is provided with a first guide surface, while the connecting block on the drill rod is provided with a clearance groove with a second guide surface. When the drill rod is inserted into the receiving groove, the fixing block is inserted into the clearance groove, and the first guide surface and the second guide surface fit together. Thus, when the movable component drives the drill rod to be inserted into the movable groove, rotating the drill rod allows it to smoothly disengage from the clearance groove and accurately insert into the insertion groove through the cooperation of the second guide surface and the first guide surface, thereby achieving rapid locking between the movable component and the hydraulic hammer body. At the same time, this design simplifies the fixing and unlocking operation steps and improves the convenience and efficiency of drill rod replacement.

[0015] Optionally, a buffer assembly is provided in the receiving groove, the buffer assembly abutting against the connecting block and located on the side of the connecting block closer to the hydraulic hammer body.

[0016] By adopting the above technical solution, after the chisel is installed, the hydraulic hammer body can drive the chisel to carry out crushing operations. During this process, the buffer component can absorb the impact force generated by the chisel during the crushing operation, reduce the direct impact on the chisel and the hydraulic hammer body, and thus extend the service life of the chisel and the hydraulic hammer body.

[0017] Optionally, the buffer assembly includes an elastic element and a buffer plate. The buffer plate is slidably disposed within the receiving groove and abuts against the connecting block. The elastic element is disposed between the buffer plate and the inner wall of the receiving groove, and the elastic element is located on the side of the buffer plate away from the connecting block.

[0018] By adopting the above technical solution, the elastic element is set between the buffer plate and the inner wall of the receiving groove, which can compress and deform when the drill rod is subjected to external impact, thereby reducing damage to the connecting block and its surrounding structure. At the same time, the buffer plate is slidably set in the receiving groove, which can flexibly adjust its position according to changes in impact force, further enhancing the buffering effect. This design not only improves the durability and reliability of the equipment, but also extends its service life and reduces maintenance costs.

[0019] Optionally, a buffer pad is provided between the buffer plate and the connecting block.

[0020] By adopting the above technical solution, the buffer pad is placed between the buffer plate and the connecting block, which can effectively absorb the impact force during the insertion of the drill rod, reduce the damage to components caused by the impact, and ensure stable contact between the connecting block and the buffer plate, thereby improving the reliability and service life of the overall structure. In addition, the buffer pad can also play a role in vibration reduction, reduce working noise, and improve operating comfort.

[0021] Optionally, the buffer assembly is provided in two sets, with the two sets of buffer assemblies respectively disposed on the support base and the movable plate, and the two sets of buffer assemblies respectively abutting against the connecting block.

[0022] By adopting the above technical solution, setting up two sets of buffer components can effectively disperse the impact force, reduce the pressure on a single buffer component, and extend its service life. Simultaneously, the two sets of buffer components are respectively installed on the support base and the movable plate, and abut against the connecting block, providing stable buffering in different directions. This further improves the stability and reliability of the system, reduces the risk of damage caused by impact, and ensures the efficient operation of the hydraulic breaker in high-intensity working environments.

[0023] Optionally, the support base and the end of the movable plate extending into the movable groove are respectively provided with a protective plate, which is used to fit against the surface of the hydraulic hammer body.

[0024] By adopting the above technical solution, the protective plate can effectively prevent external impurities from entering the moving groove, avoiding mechanical failures or wear problems caused by impurities, and improving the working stability and service life of the hydraulic breaker. At the same time, the design of the protective plate fitting snugly against the surface of the hydraulic hammer body makes the entire device structure more compact, reduces space occupation, and improves the overall aesthetics and safety of the equipment.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of the moving mechanism and the fixed components, the drill rod can be quickly replaced, which greatly reduces the replacement time and improves the work efficiency on the construction site; 2. Through the cooperation of the support base, movable plate, fixed block, reset component and connecting block, the chisel can drive the fixed block to be smoothly pushed out from the relief groove and accurately inserted into the insertion groove, so as to realize the rapid locking between the movable component and the hydraulic hammer body; 3. Through the cooperation of the elastic element and the buffer plate, the elastic element can absorb the impact force generated by the chisel during the crushing operation, reduce the direct impact on the chisel and the hydraulic hammer body, and thus extend the service life of the chisel and the hydraulic hammer body.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a triangular hydraulic breaker.

[0033] It should be noted that, in the description of this invention, the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] Reference Figure 1 and Figure 2 A triangular hydraulic breaker includes a hydraulic hammer body 1, a movable mechanism 2, and a chisel 3. The hydraulic hammer body 1 has a movable groove 11, the movable mechanism 2 is movably disposed within the movable groove 11, and the chisel 3 is detachably connected to the movable mechanism 2, with one end of the chisel 3 extending into the movable groove 11. This facilitates the hydraulic hammer body 1 striking the chisel 3, thereby causing the chisel 3 to break solids.

[0035] It should be noted that the specific structure of the hydraulic hammer body 1 and how to drive the chisel 3 to break solids in this embodiment are all conventional techniques for those skilled in the art. Therefore, they will not be described in detail in this embodiment.

[0036] Reference Figure 1 and Figure 2 The movable mechanism 2 includes a fixed component 21 and a movable component 22. The movable component 22 is slidably disposed within the movable groove 11, and the fixed component 21 is disposed between the movable component 22 and the hydraulic hammer body 1. When the movable component 22 is inserted into the movable groove 11, the chisel 3 can drive the fixed component 21 to fix the movable component 22 to the hydraulic hammer body 1.

[0037] Reference Figure 2 and Figure 3 The movable component 22 includes a support base 221 and a movable plate 222. One end of the support base 221 is slidably connected to the inner wall of the movable groove 11, and the other end extends out of the movable groove 11. In this embodiment, a limiting block 2211 is fixedly connected to the support base 221, and a limiting groove 12 is formed on the inner wall of the movable groove 11. The limiting block 2211 is slidably inserted into the limiting groove 12 to limit the support base 221, thereby making it difficult for the support base 221 to detach from the movable groove 11.

[0038] The movable plate 222 is hinged to the support base 221, allowing the movable plate 222 to rotate relative to the support base 221. When the movable plate 222 and the support base 221 are inserted into the movable groove 11, the movable plate 222 and the support base 221 can respectively fit against the inner wall of the movable groove 11, so that the hydraulic hammer body 1 can limit the movable plate 222 and the support base 221, making it difficult for the movable plate 222 to rotate relative to the support base 221.

[0039] Reference Figure 2 A receiving groove 223 is provided between the movable plate 222 and the support base 221. The shape of the receiving groove 223 is adapted to the shape design of the chisel 3, and the receiving groove 223 penetrates the end face of the support base 221 near the hydraulic hammer body 1, so that the chisel 3 can be inserted into the receiving groove 223 and extend out of the receiving groove 223.

[0040] When it is necessary to insert the drill rod 3 into the receiving slot 223, first move the support base 221 outward from the movable slot 11. The support base 221 drives the movable plate 222 to the designated position. Then, rotate the movable plate 222 away from the support base 221 to open the receiving slot 223. At this time, insert the drill rod 3 into the receiving slot 223, with one end of the drill rod 3 extending out of the receiving slot 223 to the side of the support base 221 near the movable slot 11. Next, rotate the movable plate 222 towards the support base 221, and then push the movable plate 222 and the support base 221 into the movable slot 11. Secure them using the fixing component 21, thereby enabling the replacement of the drill rod 3.

[0041] Reference Figure 2 The support base 221 and the movable plate 222 are respectively fixedly connected to a protective plate 224 at one end of the movable groove 11. When the support base 221 and the movable plate 222 are inserted into the movable groove 11, the protective plate 224 is in contact with the surface of the hydraulic hammer body 1 to effectively prevent external impurities from entering the interior of the movable groove 11, thereby avoiding mechanical failures or wear problems caused by impurities and improving the working stability and service life of the hydraulic breaker.

[0042] In this embodiment, the support base 221 can be made of high-strength alloy steel, which has good wear resistance and fatigue resistance. The movable plate 222 can be made of lightweight aluminum alloy to reduce the overall weight and facilitate quick replacement of the drill rod 3 by the operator. The protective plate 224 can be made of polyurethane, which has excellent wear resistance and shock absorption performance, effectively resisting the corrosion of the external environment, and the thickness of the protective plate 224 can be adjusted according to the actual situation.

[0043] Reference Figure 2 and Figure 4 The support base 221 and the movable plate 222 are respectively provided with sliding grooves 225, which are connected to the receiving groove 223. The fixing component 21 includes fixing blocks 211 and resetting components 212. The number of fixing blocks 211 is equal to the number of sliding grooves 225, and one fixing block 211 is slidably inserted into one sliding groove 225.

[0044] The number of reset members 212 is equal to the number of fixed blocks 211, and the reset members 212 are disposed within the slide groove 225. In this embodiment, the reset member 212 is an electromagnet, and a metal plate (not shown in the figure) is provided on the side of the fixed block 211 near the support base 221 to facilitate the attraction of the reset member 212, thereby facilitating the reset member 212 to drive the fixed block 211 to move towards the receiving groove 223. In other embodiments, the reset member 212 may also be a spring.

[0045] Reference Figure 4The fixing block 211 has a first guide surface 2111 at one end near the receiving groove 223, and the first guide surface 2111 is inclined. A connecting block 31 is fixedly connected to the drill rod 3. The connecting block 31 is located in the receiving groove 223 and is set corresponding to the fixing block 211. The connecting block 31 has a relief groove 311, and a second guide surface 312 is provided on the inner wall of the relief groove 311. When the drill rod 3 is located in the receiving groove 223, the fixing block 211 can be inserted into the relief groove 311. At this time, the first guide surface 2111 and the second guide surface 312 are parallel and abut against each other.

[0046] Reference Figure 2 and Figure 4 The inner wall of the movable groove 11 is provided with a insertion groove 13, and the limiting groove 12 communicates with the insertion groove 13. When the support base 221 and the movable plate 222 drive the drill rod 3 into the movable groove 11, the fixing block 211 approaches the insertion groove 13. At this time, rotating the drill rod 3 allows it to apply force to the first guide surface 2111 through the second guide surface 312, thereby driving the fixing block 211 to move into the insertion groove 13, so that the fixing block 211 is inserted into the insertion groove 13. This facilitates the use of the fixing block 211 to limit the support base 221 and the movable plate 222, thereby achieving a stable connection between the support base 221, the movable plate 222 and the hydraulic hammer body 1.

[0047] When the drill rod 3 drives the fixing block 211 to be inserted into the insertion slot 13, the positioning slot 311 and the fixing block 211 are misaligned, so that the fixing block 211 can always be limited by the connecting block 31, thereby making the fixing block 211 less likely to fall out of the insertion slot 13 due to vibration, which helps to improve the stability of the overall structure.

[0048] Reference Figure 2 A buffer assembly 23 is provided inside the receiving groove 223. The buffer assembly 23 abuts against the connecting block 31 and is located on the side of the connecting block 31 closer to the hydraulic hammer body 1. When the hydraulic hammer body 1 drives the chisel 3 to perform crushing operations, the buffer assembly 23 can absorb the impact force generated by the chisel 3 during the crushing operation, so as to reduce the direct impact on the chisel 3 and the hydraulic hammer body 1, thereby extending the service life of the chisel 3 and the hydraulic hammer body 1.

[0049] In this embodiment, two sets of buffer components 23 are provided. The two sets of buffer components 23 are respectively provided on the support base 221 and the movable plate 222, and the two sets of buffer components 23 respectively abut against the connecting block 31.

[0050] The buffer assembly 23 includes an elastic element 231 and a buffer plate 232. The buffer plate 232 is slidably disposed in the receiving groove 223, and the two buffer plates 232 cooperate with each other to form a ring, so that the two buffer plates 232 can more fully abut against the connecting block 31.

[0051] An elastic element 231 is disposed between the inner wall of the buffer plate 232 and the receiving groove 223, and the elastic element 231 is located on the side of the buffer plate 232 away from the connecting block 31. In this embodiment, the elastic element 231 is a spring, so that the elastic element 231 can drive the buffer plate 232 to move closer to the connecting block 31.

[0052] When the reset component 212 drives the fixing block 211 to be inserted into the clearance groove 311, the fixing block 211 can abut against the buffer plate 232, so that after the drill rod 3 is disengaged from the receiving groove 223, the fixing block 211 can limit the buffer plate 232, so that there is a gap between the buffer plate 232 and the inner wall of the receiving groove 223 away from the movable groove 11, so as to provide an insertion position for the connecting block 31 on the new drill rod 3, thereby facilitating the rapid replacement of the drill rod 3.

[0053] Reference Figure 2 A buffer pad 233 is fixedly connected to the buffer plate 232, and the buffer pad 233 can fill the space between the buffer plate 232 and the connecting block 31. In this embodiment, the buffer pad 233 is made of rubber material, which can effectively absorb impact force during the operation of the drill rod 3, thereby reducing the possibility of damage to the buffer plate 232 and the connecting block 31 due to collision, and thus improving the reliability and service life of the overall structure. In other embodiments, the buffer pad 233 can also be provided on the connecting block 31.

[0054] The implementation principle of a triangular hydraulic breaker according to an embodiment of this application is as follows: When it is necessary to replace the chisel 3, first rotate the chisel 3 so that the clearance groove 311 is close to the fixed block 211. At the same time, activate the reset component 212, which drives the fixed block 211 to disengage from the insertion groove 13 and insert into the clearance groove 311. Then move the support base 221 and the movable plate 222 outward from the movable groove 11 so that the movable plate 222 disengages from the movable groove 11. At this time, rotate the movable plate 222 away from the support base 221 to open the receiving groove 223, so that the chisel 3 can be taken out from the receiving groove 223.

[0055] Next, insert the new drill rod 3 into the receiving groove 223, and insert the connecting block 31 between the buffer plate 232 and the inner wall of the receiving groove 223, while simultaneously inserting the fixing block 211 into the clearance groove 311. Then rotate the movable plate 222 towards the support base 221 so that the movable plate 222 fits against the support base 221.

[0056] Finally, push the support base 221 and the movable plate 222 into the movable groove 11, so that the drill rod 3 enters the movable groove 11 and the fixing block 211 approaches the insertion groove 13. Then rotate the drill rod 3, and the drill rod 3 drives the fixing block 211 to be inserted into the insertion groove 13 through the connecting block 31, so as to realize the positioning of the support base 221 and the movable plate 222, thereby completing the replacement of the drill rod 3.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
