Description

Technical Field

[0001] The present invention relates to the technical field of breaker hammers, and specifically to a breaker hammer core with high strength, wear resistance and impact resistance. Background Art

[0002] The breaker hammer core is a powerful device applied in the field of demolition engineering. Driven by a hydraulic system, it can crush huge hard objects in a very short time and plays an important role in industries, mines and construction, etc. Especially in occasions such as demolishing buildings and excavating ores, the essence of the breaker hammer core is a high-speed piercing tool. When firmly installed on equipment such as excavators, users only need to apply pressure to the front, and the breaker hammer core can quickly break and crush the object to be broken. In recent years, the technology of the breaker hammer core has been continuously innovated and developed. The breaker hammer core has started to develop towards the intelligent direction. By introducing devices such as sensors, controllers and actuators, the automatic control and remote monitoring of the equipment are realized. At the same time, in order to meet the requirements of environmental protection regulations, manufacturers have continuously developed more environmentally friendly breaker hammer cores to reduce the impact of noise and vibration on the environment; During the use of the existing breaker hammer cores, various failures caused by various factors such as poor rotor balance, loose fixing of the lining plate and insufficient lubrication will cause the breaker hammer cores to malfunction. The weak striking force of the breaker hammer core will not only reduce the crushing efficiency, but also exacerbate the wear of the core and other components. At the same time, during the crushing process, the presence of iron blocks in the ore, incorrect selection of the hammer head material and poor friability of the ore will also cause wear of the breaker hammer core.

[0003] 1. Patent document CN109281604B discloses a percussion core for hydraulic crushing and a hydraulic breaker hammer. The above patent has overcome the problems that the structure of the percussion core for hydraulic crushing in the prior art is complex and a large amount of materials are required for production, resulting in high production costs.

[0004] 2. Patent document CN111519687B discloses an assembly method for a shock-absorbing component of a silent breaker hammer. The above patent has achieved a gapless fit between the first shock-absorbing pad, the second shock-absorbing pad, the core and the housing. During the use process, the main movement of the entire breaker hammer is up and down, but its shaking is mainly back and forth. The first shock-absorbing pad and the second shock-absorbing pad are arranged on the front and back sides, ensuring that the core will not swing back and forth in the housing, reducing the impact on the housing, ensuring that the core will not move around in the housing, and greatly reducing the probability of housing cracking and core failure.

[0005] 3. Patent document CN217537134U discloses a breaker hammer core. The above patent has achieved the advantages of not being easy to fall off of the flat pin, not being easy to damage the flat pin stop pin, and not being easy to fall off of the bushing stop pin.

[0006] 4. The patent document CN221663768U discloses a breaker core. The above patent realizes driving the handle to rotate manually, the handle drives the eccentric wheel to rotate, the eccentric wheel squeezes the cross plate to move, the cross plate compresses the first spring, the cross plate drives the round rod to move downward, the round rod drives the splint to move outward, and the splint no longer fixes the drill rod. This method facilitates the removal and replacement of the drill rod, thereby improving the replacement efficiency of the drill rod.

[0007] In summary, inspired by the above patent, this application has developed a function that can adjust the perpendicular relationship between the drill rod and the surface of the object to be broken, a function that can understand the hardness and structure of the object to be broken, a function that can maintain the pressure stability of the equipment, and a function that can clean the drill rod and dissipate heat from the equipment, in order to solve the problems of increased wear of the drill rod, low crushing efficiency, increased equipment loss, increased energy consumption, the frequency of the breaker core fluctuating rapidly and slowly during operation, low impact force, and decreased equipment performance existing in the existing breaker core.

[0025] Embodiment 1: Please refer to Figure 1 、 Figure 2 and Figure 3 , a high-strength, wear-resistant and impact-resistant breaker core, comprising a body 1, a controller 8, a drill rod 2, a hydraulic assembly 7 and a correction assembly 6. The correction assembly 6 and the hydraulic assembly 7 are connected to the controller 8 through signal lines; A controller 8 is installed in the middle of the inner wall of the body 1, a drill rod 2 is installed at the lower part of the inner wall of the body 1, a correction assembly 6 is installed on the upper side of the outer wall of the drill rod 2, and a hydraulic assembly 7 is installed on the upper side of the outer wall of the correction assembly 6; The correction assembly 6 includes: a magnetostrictive displacement sensor 4, a rotation module 10 and a connector 11. The magnetostrictive displacement sensor 4 and the rotation module 10 are connected to the controller 8 through signal lines, and the rotation module 10 is connected to the drill rod 2 through the connector 11; A magnetostrictive displacement sensor 4 is installed on the left side of the outer wall of the body 1, a rotation module 10 is installed on the upper side of the outer wall of the drill rod 2, and a connector 11 is installed on the lower side of the outer wall of the rotation module 10; The rotating module 10 includes: an outer ring 12, an inner ring 13, a rotating shaft 14, an adjusting gear 15, a transmission rod 16 and a knob 17. The rotating shaft 14 is connected to the transmission rod 16 through the adjusting gear 15, and the knob 17 is connected to the controller 8 through a signal line. An inner ring 13 is installed on the upper side of the outer wall of the drill rod 2, an outer ring 12 is installed on the outer side of the inner ring 13, a rotating shaft 14 is installed on the inner side of the outer wall of the inner ring 13, an adjusting gear 15 is installed on the upper side of the outer wall of the rotating shaft 14, a transmission rod 16 is installed on the left side of the outer wall of the adjusting gear 15, and a knob 17 is installed on the upper side of the outer wall of the transmission rod 16; Furthermore, after the operator installs the breaker hammer movement, the operator connects the drill rod 2 to the rotating module 10 through the connector 11 when replacing the drill rod 2. The magnetostrictive displacement sensor 4 is provided with a waveguide, a movable magnetic ring and an electronic chamber. The magnetostrictive displacement sensor 4 uses the magnetostrictive principle to generate a strain pulse signal through the intersection of two different magnetic fields to accurately measure the position. When a current pulse is generated in the electronic chamber, the pulse is transmitted in the waveguide and a circular magnetic field is generated outside the waveguide. When the magnetic field intersects with the magnetic field generated by the movable magnetic ring installed on the drill rod 2, due to the effect of magnetostriction, the strain mechanical pulse signal generated in the waveguide will be transmitted in the waveguide at a fixed sound speed and detected by the electronic chamber.

When the angle between the drill rod 2 and the surface of the object to be crushed is not 90°, the operator controls the knob 17 to rotate through the controller 8, and drives the rotating shaft 14 to adjust the angle between the drill rod 2 and the surface of the object to be crushed through the transmission rod 16 and the adjustment gear 15, and stops adjusting when the angle is 90°, thereby realizing the function of adjusting the vertical relationship between the drill rod 2 and the surface of the object to be crushed, solving the problems of increased wear of the drill rod 2, damage to the piston rod 34 and low crushing efficiency, being able to generate greater impact force, reducing energy dispersion and energy consumption, extending the service life of the equipment, and improving the crushing efficiency of the equipment.

[0026] Example 2: Please refer to Figure 1 , Figure 2 and Figure 5 , a high-strength wear-resistant and impact-resistant breaker hammer core, a detection component 9 is installed on the left side of the outer wall of the body 1, and the detection component 9 is connected to the controller 8 through a signal line; The detection component 9 includes: an ultrasonic sensor 3 and a hardness detection module 5, and the ultrasonic sensor 3 and the hardness detection module 5 are connected to the controller 8 through a signal line; An ultrasonic sensor 3 is installed on the left side of the outer wall of the body 1, and a hardness detection module 5 is installed on the left side of the outer wall of the body 1; The hardness detection module 5 includes: a compressor 29, a first spring 30, a speed sensor 31, and an impact block 32.

On the right side of the outer wall of the compressor 29, a speed sensor 31 is installed; Furthermore, inside the ultrasonic sensor 3, there are a transmitter, a receiver, and a control unit. High-frequency acoustic wave pulses are emitted to the object to be broken through the transmitter. After encountering the object to be broken, they are reflected, refracted, or scattered. After the receiver receives the reflected echo, it is converted into an electrical signal. By analyzing the time, amplitude, and phase changes of the reflected echo, the internal structure of the object to be broken can be inferred, including the position, size, and nature of defects, etc. At the same time, because objects of different materials have different propagation speeds and attenuation characteristics for ultrasonic waves, the material of the object to be broken can also be detected. After completing the detection of the material and internal defects of the object to be broken, the hardness detection module 5 compresses the first spring 30 through the compressor 29, and launches the impact block 32 towards the object to be broken at a certain speed. The speed sensor 31 detects the meeting speed of the impact block 32 after hitting the surface of the object to be broken. The hardness of the object to be broken is calculated through HL = 1000×Vr / Va, where HL is the Richter hardness value, Vr is the rebound speed of the impact block 32, and Va is the impact speed of the impact block 32. It realizes the function of understanding the hardness and structure of the object to be broken, solves the problems of low crushing efficiency, increased equipment loss, and increased energy consumption, can optimize the crushing method of the breaker core, reduces the crushing energy consumption, improves the crushing efficiency, and reduces the impact and wear on the breaker core.

At the same time, when rapid action or large flow rate oil supply is required, the first accumulator 21 and the second accumulator 22 can quickly release the stored pressure oil to instantly meet the needs of the hydraulic cylinder 19. While absorbing pressure fluctuations and replenishing flow, the first accumulator 21 and the second accumulator 22 can also absorb the heat inside the equipment, thereby reducing the operating temperature of the equipment.

The rotation module 10 includes: an outer ring 12, an inner ring 13, a rotating shaft 14, an adjusting gear 15, a transmission rod 16, and a knob 17. The rotating shaft 14 is connected to the transmission rod 16 through the adjusting gear 15, and the knob 17 is connected to the controller 8 through a signal wire. The inner ring 13 is installed on the upper side of the outer wall of the drill rod 2, the outer ring 12 is installed on the outer side of the outer wall of the inner ring 13, the rotating shaft 14 is installed on the inner side of the outer wall of the inner ring 13, the adjusting gear 15 is installed on the upper side of the outer wall of the rotating shaft 14, the transmission rod 16 is installed on the left side of the outer wall of the adjusting gear 15, and the knob 17 is installed on the upper side of the outer wall of the transmission rod 16. Furthermore, the structure of the rotation module 10 is that the outer ring 12 wraps the inner ring 13. The main body of the rotation module 10 is arranged inside the inner ring 13. The outer ring 12 wrapping the inner ring 13 forms a nested structure, making the connection between the drill rod 2 and the rotation module 10 firmer, not easily loosening and falling off. During the working process of the breaker core, the close fit between the outer ring 12 and the inner ring 13 can withstand greater impact force and torque. When the drill rod 2 is subjected to impact force, the connection method of the outer ring 12 wrapping the inner ring 13 can disperse the impact force to a larger contact surface, reducing the pressure borne per unit area, being able to reduce the wear and damage of the equipment, achieving the improvement of the impact resistance of the breaker core, solving the problems of easy damage of the equipment, increased equipment failure rate, and low working efficiency, being able to increase the stability and reliability of the connection, being able to disperse the impact force generated during the operation, and extending the service life of the equipment.

[0030] Working principle: After the operator installs the breaker core, when replacing the drill rod 2, the drill rod 2 is connected to the rotating module 10 through the connector 11. When the magnetostrictive displacement sensor 4 generates an electric current pulse in the electronic chamber, the pulse is transmitted in the waveguide tube and generates a circumferential magnetic field outside the waveguide tube. When the magnetic field intersects with the magnetic field generated by the movable magnetic ring installed on the drill rod 2, due to the magnetostrictive effect, a strain mechanical pulse signal will be generated in the waveguide tube and transmitted in the waveguide tube at a fixed sound speed and detected by the electronic chamber. By measuring the transmission time of the strain mechanical pulse signal, the vertical relationship between the drill rod 2 and the object to be broken is measured, and the information is transmitted to the controller 8. When the angle between the drill rod 2 and the surface of the object to be broken is not 90°, the operator controls the rotation of the knob 17 through the controller 8, and drives the rotating shaft 14 through the transmission rod 16 and the adjusting gear 15 to adjust the angle between the drill rod 2 and the surface of the object to be broken, and stops adjusting when the angle is 90°. At the same time, the structure of the rotating module 10 is that the outer ring 12 wraps the inner ring 13, and the main body of the rotating module 10 is arranged inside the inner ring 13. The outer ring 12 wraps the inner ring 13 to form a nested structure, making the connection between the drill rod 2 and the rotating module 10 firmer and not easy to loosen and fall off. During the working process of the breaker core, the close fit between the outer ring 12 and the inner ring 13 can withstand greater impact force and torque. When the drill rod 2 is subjected to an impact force, the connection method of the outer ring 12 wrapping the inner ring 13 can disperse the impact force to a larger contact surface, reducing the pressure borne per unit area; The ultrasonic sensor 3 infers the internal structure of the object to be broken, including the defect position, size and nature, etc., by analyzing the time, amplitude and phase changes of the reflected echo. At the same time, due to the different propagation speeds and attenuation characteristics of ultrasonic waves in objects of different materials, the material of the object to be broken can also be detected. After completing the detection of the material and internal defects of the object to be broken, the hardness detection module 5 compresses the first spring 30 through the compressor 29, and launches the impact block 32 towards the object to be broken at a certain speed. The speed sensor 31 detects the meeting speed of the impact block 32 after hitting the surface of the object to be broken, and calculates the hardness of the object to be broken through HL = 1000×Vr / Va. Among them, HL is the Richter hardness value, Vr is the rebound speed of the impact block 32, and Va is the impact speed of the impact block 32; A first accumulator 21 and a second accumulator 22 are respectively arranged at the oil inlet 38 and the oil outlet 39 of the hydraulic cylinder 19 to remove the pressure fluctuations generated during the oil inlet and oil outlet processes of the hydraulic cylinder 19. At the same time, when rapid movement or large-flow oil supply is required, the first accumulator 21 and the second accumulator 22 can quickly release the pressurized oil stored therein to instantaneously meet the requirements of the hydraulic cylinder 19. While absorbing pressure fluctuations and supplementing flow rate, the first accumulator 21 and the second accumulator 22 can also absorb the heat inside the equipment, reducing the working temperature of the equipment. Inside the hydraulic cylinder 19, a lengthened cylinder body 33 provides a longer movement distance for the piston rod 34, increasing the force when the piston rod 34 reaches the drill rod 2 position; The temperature sensor 23 focuses the infrared rays radiated by the hydraulic component 7 on the infrared sensor through an optical system and converts them into electrical signals. After being amplified, filtered, and converted by the signal processor, the temperature information is transmitted to the controller 8. During the operation of the hydraulic component 7, the water flow in the circulation pipe 26 exchanges heat with the water flow in the water tank 24 to ensure the normal temperature inside the equipment. After the breaker core completes the breaking work, the operator opens the water valve 27 through the controller 8 to connect the pressurizing unit 28, the water tank 24, and the nozzle 25. The pressurizing unit 28 pressurizes the water flow in the water tank 24 and flushes the drill rod 2 through the nozzle 25.
