Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to a self-resetting pneumatic buffer low-sound-pressure breaker hammer needle. Background Technology

[0002] At present, noise reduction technology for impact tools used in construction mainly focuses on two approaches: structural buffering and air propagation path treatment, but there are still obvious shortcomings overall.

[0003] On the one hand, traditional rigid impact hammers, combined with passive buffering elements such as rubber pads and buffer seats, can only reduce the impact peak to a limited extent. They lack adaptive adjustment capabilities for different working conditions such as different media, humidity, temperature, and crushing depth. The impact energy is still transmitted in the form of spikes, which easily leads to rebound and high-frequency noise. On the other hand, although pneumatic buffering schemes using air chambers can achieve a certain amount of energy absorption through gas compression, they are mostly static or semi-adaptive structures, lacking precise valve control and pressure regulation, resulting in uneven energy release and peak fluctuation problems. At the same time, external sound-absorbing covers or sound-absorbing materials mainly act on airborne noise, with limited suppression of solid-borne sound paths, and it is difficult to form a stable and effective local sound field control at the moment of impact. In addition, existing technologies generally lack a unified closed-loop control mechanism for energy buffering, acoustic blocking, and reset processes, resulting in insufficient self-reset capability, easy generation of secondary impacts, and affecting equipment reliability.

[0004] Therefore, to solve the above problems, a self-resetting pneumatic buffered low sound pressure breaker needle is needed, which can balance crushing efficiency and low sound pressure output, and achieve adaptive buffering and release of impact energy and effective blocking of sound propagation path. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide a self-resetting pneumatic buffered low sound pressure breaker hammer needle that can balance crushing efficiency and low sound pressure output, and achieve adaptive buffering and release of impact energy and effective blocking of sound propagation path.

[0006] The self-resetting pneumatic buffer low sound pressure breaker needle of the present invention includes a chisel body, a high-pressure air chamber and damping valve integrated module disposed in the chisel body, a follow-up vacuum sound-absorbing sleeve, and a control and drive integrated module.

[0007] The high-pressure air chamber and damping valve integrated module is located in the middle or near the end of the drill rod body. It is used to convert the impact energy into gas compression energy during the impact process and release it in a controlled manner through the controllable damping valve to reduce the impact peak.

[0008] The follow-up vacuum sound-absorbing sleeve is fitted outside the drill rod body to create a local vacuum environment at the moment the drill rod contacts the broken medium, thereby blocking the solid sound transmission path and attenuating the sound wave propagation.

[0009] The control and drive integrated module is communicatively connected to the high-pressure air chamber, damping valve, and follow-up vacuum sound-absorbing sleeve. It is used for closed-loop control based on force, displacement, and pressure signals to realize the adjustment of impact energy release and self-reset control after the operation is completed.

[0010] Furthermore, the high-pressure gas chamber includes a sealed energy storage chamber. The volume of the energy storage chamber and the initial inflation pressure are designed to match the impact peak value, impact duration, and spectral characteristic parameters to achieve buffered storage and stable release of impact energy.

[0011] Furthermore, the damping valve is a microstructure adjustable valve, whose opening degree and opening rate are dynamically adjusted according to the real-time impact force signal and air chamber pressure signal to achieve staged or continuous energy release.

[0012] Furthermore, the follow-up vacuum sound-absorbing sleeve includes a flexible outer layer structure and a locally rigid support structure, which forms a local negative pressure zone by rapidly venting air or instantaneously expanding the volume at the moment of contact with the drill rod.

[0013] Furthermore, the integrated control and drive module includes a sensor array, a signal processing unit, and a control algorithm module. The sensor array includes a force sensor, a displacement sensor, and a temperature sensor, which are used to acquire multimodal data of the impact process.

[0014] Furthermore, the control algorithm module adopts a closed-loop adaptive control strategy, which presets an energy release curve before impact contact and dynamically adjusts the air chamber pressure release rate and damping valve opening based on real-time feedback during the impact process, so as to achieve impact peak suppression and stable crushing output.

[0015] Furthermore, it also includes a self-resetting mechanism, which is used to drive the chisel body to return to its initial position after the crushing action is completed. The reset action is controlled by the control and drive integrated module.

[0016] Furthermore, it also includes a safety protection module, which includes an abnormal air chamber pressure detection unit, a valve jamming detection unit, and a vibration over-limit protection unit, used to perform pressure limiting release or power-off protection under abnormal conditions.

[0017] Furthermore, the high-pressure air chamber is a multi-chamber parallel structure, with each chamber controlled by independent or linked valves to achieve graded energy storage and stepped energy release, in order to adapt to crushing conditions of different hardness and depth.

[0018] Furthermore, the control and drive integrated module also includes an online learning unit, which is used to analyze historical impact condition data and update control parameters to adapt to working environments under different concrete grades, humidity and temperature changes.

[0019] The beneficial effects of this invention are as follows: The self-resetting pneumatic buffer low sound pressure breaker needle disclosed in this invention achieves active absorption and controllable release of impact energy by integrating a high-pressure air chamber and a damping valve inside the breaker needle. A follow-up vacuum sound-absorbing sleeve is fitted on the outside of the breaker needle to quickly establish a local vacuum environment at the moment of contact. Combined with adaptive control based on sensor signals, the closed-loop energy storage and release and self-resetting process are coordinated and controlled, thereby significantly reducing noise during the crushing process and improving the comfort of the working environment and the efficiency of operation.

[0025] The present invention will be further described below with reference to the accompanying drawings, as shown in the figures:

[0026] This embodiment discloses a self-resetting pneumatic buffer low sound pressure breaker needle, including a chisel body, a high-pressure air chamber and damping valve integrated module, a follow-up vacuum sound-absorbing sleeve, and a control and drive integrated module disposed in the chisel body;

[0027] The high-pressure air chamber and damping valve integrated module is located in the middle or near the end of the drill rod body. It is used to convert the impact energy into gas compression energy during the impact process and release it in a controlled manner through the controllable damping valve to reduce the impact peak.

[0028] The follow-up vacuum sound-absorbing sleeve is fitted outside the drill rod body to create a local vacuum environment at the moment the drill rod contacts the broken medium, thereby blocking the solid sound transmission path and attenuating the sound wave propagation.

[0029] The control and drive integrated module is communicatively connected to the high-pressure air chamber, damping valve, and follow-up vacuum sound-absorbing sleeve. It is used for closed-loop control based on force, displacement, and pressure signals to realize the adjustment of impact energy release and self-reset control after the operation is completed.

[0030] The drill rod body is made of high-strength alloy steel to meet the structural strength and wear resistance requirements under high-frequency impact conditions. The high-pressure air chamber and damping valve integrated module are embedded in the middle of the drill rod or near the force-bearing end to shorten the energy transmission path and improve buffering efficiency. The follow-up vacuum sound-absorbing sleeve is installed on the outside of the drill rod through a tight fit or sliding seal structure and can respond synchronously with the axial movement of the drill rod. The control and drive integrated module is electrically or pneumatically connected to each module through the existing embedded control unit, thereby forming an integrated collaborative system to realize impact energy regulation, sound propagation suppression, and self-reset control after operation.

[0031] In this embodiment, the high-pressure gas chamber adopts a closed energy storage cavity structure. The cavity can be formed through embedded processing or modular assembly. Its volume is designed according to the target impact energy level and can be determined by a combination of theoretical calculation and experimental calibration. The initial inflation pressure is set by pre-filling with an external gas source or by setting an internal gas storage unit, and can be adjusted according to different construction environments. Specifically, by converting the mechanical energy during the impact process into gas compression energy, the impact peak is effectively weakened, and a relatively smooth force output curve is formed during the subsequent release process, thereby balancing crushing efficiency and noise reduction requirements.

[0032] In this embodiment, the damping valve is a microstructure adjustable valve, which can be internally configured with multi-stage flow channels or micropore structures to achieve precise control of gas flow resistance. The valve's opening degree and opening rate can be dynamically adjusted based on real-time acquired impact force and air chamber pressure signals. Specifically, the valve can adopt an electrically controlled proportional valve or a piezoelectrically driven valve structure to achieve millisecond-level response speed, thereby supporting the phased release or continuous smooth release of impact energy and avoiding the sudden energy release phenomenon present in traditional pneumatic systems.

[0033] In this embodiment, the follow-up vacuum sound-absorbing sleeve includes a flexible outer layer and a locally rigid support frame. The flexible layer can be made of wear-resistant rubber or composite elastic material, and the rigid support structure is used to maintain the stability of the sleeve shape. At the instant the drill rod contacts the broken medium, the air in the local working chamber is rapidly discharged or the pressure drops through the set rapid exhaust channel or instantaneous volume expansion structure, thereby forming a short-term negative pressure zone. This negative pressure zone can effectively weaken the coupling propagation path of sound waves between solids and air, especially having a significant suppression effect on high-frequency noise.

[0034] In this embodiment, the integrated control and drive module includes a multi-type sensor array, a signal processing unit, and a control algorithm module. The sensor array is preferably distributed at the key stress-bearing parts of the drill rod to collect information such as impact force, displacement change, and ambient temperature in real time. The signal processing unit filters, extracts features, and identifies the state of the collected data, and inputs the processing results into the control algorithm module, thereby providing a reliable data foundation for subsequent control decisions.

[0035] In this embodiment, the control algorithm module adopts a closed-loop adaptive control strategy, which specifically includes a preset stage and a real-time adjustment stage: before impact contact, an energy release curve is preset using historical data or an empirical model; during the impact process, the rate of change of air chamber pressure and the opening of the damping valve are dynamically adjusted according to the real-time feedback signal to make the impact force output tend to be smooth, thereby effectively suppressing peak impact and maintaining a stable crushing effect; this control strategy can be implemented through an embedded controller and supports online parameter updates.

[0036] In this embodiment, a self-resetting mechanism is also included. The self-resetting mechanism can be an elastic reset structure, a pneumatic reset structure, or an electrically driven reset structure, which is installed at the rear end or support part of the drill rod body. After the crushing action is completed, the control and drive integrated module outputs a control signal to drive the self-resetting mechanism to act, so that the drill rod quickly returns to the initial position, thereby avoiding secondary impact caused by stagnation or rebound, and improving operational safety and continuous operation efficiency.

[0037] This embodiment also includes a safety protection module, which is used to improve operational reliability. The safety protection module includes an abnormal air chamber pressure detection unit, a valve jamming detection unit, and a vibration over-limit protection unit. When the air chamber pressure is detected to exceed a set threshold, a pressure limit release operation is automatically performed. When an abnormal valve response is detected, redundant control or shutdown protection can be triggered. When the vibration amplitude exceeds the safe range, the drive signal can be cut off, thereby avoiding equipment damage or safety accidents.

[0038] In this embodiment, the high-pressure air chamber adopts a multi-chamber parallel structure design, and each chamber can be adjusted by independent valves or linkage control. By controlling the activation sequence and pressure release path of different chambers, graded energy storage and stepped energy output can be achieved, thereby adapting to crushing requirements of different intensities and depths and improving the system's adaptability under complex working conditions.

[0039] In this embodiment, the control and drive integrated module also includes an online learning unit. This unit can analyze historical impact data, environmental parameters, and operational effects, and dynamically update the control strategy through machine learning or parameter optimization algorithms. Specifically, it can automatically adjust the air chamber pressure setting and valve control curve according to different concrete grades, humidity, and temperature conditions, thereby continuously optimizing crushing efficiency and noise reduction performance, and achieving adaptive performance improvement.

[0040] To better understand the self-resetting pneumatically buffered low sound pressure hydraulic breaker needle and related control of the present invention, the following examples are provided for further explanation:

[0041] Example 1. A low-sound-pressure breaking cycle is completed through closed-loop control involving sensing, energy storage, slow release, vacuum barrier, and self-resetting. The specific steps are as follows:

[0042] 1) Preparation phase before operation. The system performs a self-check on the sensor array to ensure that the signal channels for force sensing, displacement sensing, temperature, and chamber pressure are normal; at the same time, the control unit presets an initial energy storage and release strategy based on the site conditions, including the capacity setting of the high-pressure air chamber, the initial air pressure, and the initial shape of the valve opening curve. To adapt to different concrete grades and humidity and temperature conditions, the system quickly replays historical working conditions and initializes parameters before entering operation, forming a preset predictive release curve template.

[0043] 2) S1—Energy Storage Buffer Stage: Before the drill bit actually contacts the hard medium, input data comes from multi-modal signals such as force, displacement, and temperature, as well as the current pressure information of the cavity. The control logic maps the impact energy to a combination of the capacity of the high-pressure gas cavity and the initial gas pressure, so that the impact energy is first stored in the high-pressure gas cavity through gas compression. As the impact is about to enter the hard medium, the control unit evaluates the changes in the force-displacement curve in real time and dynamically regulates the pressure inside the cavity through predictive algorithms to ensure that the energy storage accumulates in a way that meets the low peak value requirements.

[0044] 3) S2—Slow Release Stage: After the impact enters the hard medium stage, the control unit dynamically adjusts the valve damping coefficient to gradually increase the valve opening degree according to the required energy release curve, and ensures the smoothness of the opening and closing sequence through hysteresis characteristics. The output of this stage is a directional release of energy in the early stage of the impact, so that the evolution of the impact force over time presents a smooth curve, significantly reducing the peak value and suppressing rebound.

[0045] 4) S3—Local Vacuum Barrier Formation Stage: At the moment of contact, the follow-up vacuum sound-absorbing sleeve rapidly expels air from the local cavity in the contact area, simultaneously reducing the pressure in the adjacent space to create a local vacuum environment. This local vacuum environment blocks the solid-borne sound transmission path, reducing sound coupling and propagation. Simultaneously, combined with external convection and sound-absorbing materials, it reduces the airborne sound energy. Key parameters include vacuum build-up time, cavity exhaust rate, and the barrier performance of the outer sleeve material, all aimed at achieving a rapid barrier at the millisecond level.

[0046] 5) S4—Adaptive Closed-Loop and Self-Reset Stage: The integrated control and drive module continuously monitors changes in cavity pressure, valve opening rate, and the working status of the sound-absorbing sleeve. Dynamic adjustment of the impact process is achieved through sliding window analysis and adaptive threshold adjustment. Finally, after the crushing stage ends, the self-reset mechanism is triggered, causing the drill rod to quickly return to its initial position, completing one full crushing cycle and preparing for the next round of work. To improve robustness, the system has anomaly monitoring and fault self-recovery mechanisms, such as abnormal air cavity pressure detection, valve jamming protection, and power-off for over-limit vibration.

[0047] 6) Results and Evaluation. Without changing the basic transmission efficiency of crushing force, low noise output is achieved through active buffering and barrier mechanisms; under different concrete grades, humidity and temperature conditions, closed-loop adaptive control can quickly adjust the release curve and vacuum jacket working state to ensure stable low noise output and lower peak impact.

[0048] Example 2. Taking the device-level structure and system integration as the main line, describe in detail the physical structure, coupling method, working interface and safety design of each module.

[0049] 1) Module A: Compact integration of a high-pressure gas chamber and a damping valve. This module is embedded in the middle or near the end of the hydraulic breaker needle. The chamber includes a main chamber and several auxiliary chambers to achieve segmented energy storage. The initial gas pressure is set through the seals and pressure regulating mechanism of the sealed chamber, and a microstructured damping valve is used to achieve a high degree of control over the gas flow. The valve is a miniature valve controlled by an actuator, featuring adjustable opening, hysteresis, and thermal expansion compensation design to ensure long-term stable operation in high-frequency vibration environments. The chamber and valve body achieve overall rigidity and mass balance through high-strength materials and lightweight structural components, and a pressure sensor is provided to provide real-time feedback of the internal pressure.

[0050] 2) Module B: Follow-up Vacuum Absorbing Sleeve. Covering the outside of the drill rod, it employs a flexible-rigid transition structure to cope with high-frequency vibrations and displacements caused by impact. The vacuum chamber rapidly reduces the air volume within the local cavity through a rapid exhaust mechanism, creating a local vacuum environment. The outer casing material must possess wear resistance, heat resistance, and impact resistance, and be equipped with a sealing structure to prevent long-term leakage. This module works collaboratively with the pneumatic buffer module at the pneumatic circuit and control levels to ensure that the follow-up vacuum sleeve can quickly establish and maintain a local acoustic barrier during valve opening and energy storage release phases.

[0051] 3) Module C: Integrated Control and Drive Module. This module integrates a force sensor array, displacement sensor, temperature sensor, air chamber pressure sensor, valve actuator, and an execution unit for the energy release control algorithm. The integrated control system coordinates the operation of the three core modules in a closed-loop manner: high-pressure air chamber energy storage, damping valve opening rate, and the working status of the vacuum sound-absorbing sleeve. The control unit employs an adaptive algorithm, combining historical operating conditions for online learning and parameter updates, outputting timing control signals for valve opening / closing, chamber pressure adjustment commands, and self-reset trigger control signals. The system also features anomaly monitoring and fault self-recovery mechanisms, such as chamber pressure anomaly detection, valve jamming protection, and over-limit vibration power-off, to ensure operational safety and equipment reliability.

[0052] 4) System Coupling and Safety Design. The three main modules are efficiently coupled through mechanical connection points, air passages, and electrical interfaces. The system features a protective housing, interface protection, and quick-maintenance interfaces for easy on-site maintenance and replacement. Internally, the system incorporates redundant paths and a fault self-recovery process, enabling it to switch to a safe operating mode or automatically reset in the event of critical component failure, preventing secondary impacts or abnormal vibrations during operation.

[0053] 5) Alternatives and scalability. The solution can employ a multi-cavity parallel structure to increase energy storage capacity, or introduce a segmented venting curve to improve the stepped energy release. This design enhances the system's adaptability to impact requirements at different depths and in different media, improving overall flexibility and scalability.

[0054] Example 3. Several variant strategies and special application scenarios are given to demonstrate the applicability and flexibility of the present invention under different field conditions.

[0055] 1) Variation of multi-cavity parallel energy storage structure. To improve energy storage capacity and impact energy buffering capability, module A can adopt a multi-cavity parallel or pressure-dividing cavity structure to form a wider energy storage spectrum. The parallel cavities are independently controlled through independent valves / throttling mechanisms, enabling more complex energy release curves, further reducing peak output and adapting to crushing scenarios of varying depths.

[0056] 2) Segmented release curve strategy. The valve opening curve can employ different release strategies at different stages. For example, a smooth release in the initial stage to avoid impact spikes, a slight acceleration in the middle stage to maintain effective transmission, and a fine contraction at the end to reduce rebound. This strategy is achieved through online parameter adjustment of the adaptive control module, which can dynamically switch the release steps according to the on-site operating conditions.

[0057] 3) Environmental Adaptation and Online Learning Module. The system incorporates an online learning module that analyzes and updates strategy parameters based on historical operating data to improve robustness to environmental conditions such as different concrete grades, humidity, and temperature. By learning from previous operating conditions, the control system can quickly converge to a reasonable operating strategy when encountering new field conditions, ensuring stable low-noise output.

[0058] 4) Cross-platform compatibility and networked control. To address different control systems and field network environments, the control program stored on the computer-readable storage medium features mechanisms such as cross-platform compatibility, encrypted data transmission, integrity verification, and access control to ensure the security and stability of field applications. It also provides version management, online updates, and rollback capabilities, facilitating rapid field deployment and managing risks associated with historical versions.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
