Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically to a hydraulic breaker pressure boosting and impact-resistant device. Background Technology

[0002] In today's engineering construction field, various construction projects are constantly emerging, such as road and bridge construction, urban building demolition, mining, and tunnel excavation. The demand for efficient and reliable construction equipment is growing daily. With the continuous expansion of project scale and the increasing complexity of construction environments, traditional construction equipment is gradually revealing many shortcomings under certain working conditions, making it difficult to meet the stringent requirements of engineering construction in terms of efficiency, quality, safety, and environmental protection. Traditional hydraulic breakers often suffer from insufficient impact force when dealing with hard rocks, high-strength concrete, and other difficult-to-crush materials, resulting in low crushing efficiency. This not only prolongs the construction cycle and increases construction costs but may also affect the overall project schedule. Furthermore, existing hydraulic breakers do not fully utilize energy during operation; a large amount of energy is wasted during impact and is not effectively recovered and reused. For example, the residual energy after each impact and the piston recoil energy are not fully stored and utilized. The energy used to power the next strike is converted into energy, resulting in a low overall energy utilization rate for hydraulic breakers. Hydraulic breakers generate significant impact force and vibration during operation, causing considerable wear and tear on their components, reducing their lifespan. This vibration is also transmitted to other parts of the construction machinery, affecting its stability and reliability. Furthermore, the intense vibration negatively impacts the surrounding environment and operators, causing noise pollution and reduced operational comfort. Under complex construction conditions, such as prolonged continuous operation or harsh weather conditions, the hydraulic system of the hydraulic breaker may experience pressure fluctuations and excessively high oil temperatures, affecting system stability and reliability. This can lead to a decline in the performance of the hydraulic breaker, or even malfunctions, disrupting the normal progress of construction projects. To improve construction efficiency and quality, reduce construction costs, minimize environmental impact, and ensure the safety and health of construction workers, there is an urgent need to improve and innovate existing hydraulic breaker technology.

[0003] However, existing technologies have the following problems in practical use:

[0004] When the entire device is in use, it cannot effectively improve the crushing efficiency of materials, especially for materials with high hardness or large volume. It cannot complete the crushing operation faster, which greatly reduces the working efficiency of engineering construction and mining. The impact resistance of the breaker is insufficient, and it does not realize the function of energy storage and buffering. It is easy to cause the impact of pressure and flow fluctuations on the system. It cannot directly absorb and buffer the impact and vibration generated by the breaker, which reduces the service life of the equipment. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1 to 6 This utility model provides a hydraulic breaker pressure boosting and impact-resistant device, which is applied to engineering construction scenarios. In this embodiment, the structure of the hydraulic breaker pressure boosting and impact-resistant device is improved to give it the advantages of stability and safety.

[0029] Example 1:

[0030] Please see Figure 1 , Figure 2 and Figure 6 This utility model provides a technical solution: a hydraulic breaker pressure boosting and impact-resistant device, including a main body 1. A limit frame 6 is snapped onto the outer wall of the main body 1. A buffer pad 7 is threadedly connected to the bottom of the limit frame 6. A fixing frame 8 is welded to one side of the main body 1. A breaker rod 9 is fixedly installed at the bottom of the main body 1. A through pin 20 is threadedly connected to the outer wall of the limit frame 6. The through pin 20 passes through the interior of the limit frame 6 and is threadedly connected to the outer wall of the main body 1. Therefore, the setting of the fixing frame 8 enhances the connection stability between the main body 1 and the external equipment. By welding, the fixing frame 8 is firmly combined with the main body 1, ensuring that the main body 1 can be stably installed on the external equipment, such as an excavator, during the operation of the hydraulic breaker, preventing displacement or shaking of the hydraulic breaker due to vibration and impact, thereby ensuring the accuracy and efficiency of the breaker operation. The breaker rod 9, as the direct action component of the hydraulic breaker, is connected to the main body... The fixed installation of 1 ensures that the enhanced impact force can be effectively transmitted to the material to be crushed under the action of the pressure-increasing and impact-resistant device. This fixed installation method guarantees the connection strength between the crushing rod 9 and the main body 1, so that the crushing rod 9 will not loosen or fall off when subjected to strong impact force, thereby improving the reliability and service life of the breaker hammer, and thus improving the efficiency and quality of the entire crushing operation. The threaded connection of the through pin 20 not only enhances the connection strength between the limit frame 6 and the main body 1, preventing the limit frame 6 from shifting or falling off during the operation of the breaker hammer, but also ensures the effectiveness of the limit frame 6 in limiting the buffer pad 7. Through this stable connection structure, the buffer pad 7 can always be accurately located in the predetermined position, effectively absorbing and buffering the impact force and vibration force of the breaker hammer, protecting the key components of the breaker hammer, and extending the service life of the equipment.

[0031] Example 2:

[0032] Please see Figure 3 and Figure 4 In order to ensure that the hydraulic oil does not leak during transmission and to guarantee the normal operation of the entire hydraulic system, a booster cylinder 2 and a high-pressure oil pipe 3 are installed.

[0033] The main body 1 houses a booster cylinder 2. A high-pressure oil pipe 3 is mounted on the top of the booster cylinder 2. A pressure gauge 10 is threadedly connected to the outer wall of the booster cylinder 2. A base support 11 is threadedly connected to the bottom of the booster cylinder 2. A connecting pipe 12 is threadedly connected to the top of the booster cylinder 2. A retaining ring 13 is threadedly connected to the bottom of the high-pressure oil pipe 3. The bottom of the retaining ring 13 is threadedly connected to the internal thread of the connecting pipe 12. Therefore, the threaded connection of the pressure gauge 10 facilitates installation and disassembly while ensuring a tight and stable connection. Through its connection to the outer wall of the booster cylinder 2, the pressure gauge 10 can accurately monitor pressure changes inside the booster cylinder 2 in real time. Operators can use the reading of the pressure gauge 10 to promptly understand the working status of the booster cylinder 2, ensuring its operation within a safe and reasonable pressure range. This effectively prevents damage to the booster cylinder 2 and the entire breaker system due to excessively high or low pressure, ensuring the normal operation and service life of the equipment. The base support 11 is threadedly connected to... The bottom of the booster cylinder 2 provides a stable support, which can withstand the weight of the booster cylinder 2 itself and various forces generated during operation, preventing the booster cylinder 2 from tilting or shifting due to uneven force. This ensures the accuracy and stability of the booster cylinder 2's installation position inside the main body 1, thereby ensuring the normal operation of the booster cylinder 2 and its coordination with other components. The connecting pipe 12 can accurately introduce the hydraulic oil delivered from the high-pressure oil pipe 3 into the booster cylinder 2, ensuring the smoothness and stability of hydraulic oil transmission. Its reasonable design and tight connection with the booster cylinder 2 enable the booster cylinder 2 to effectively pressurize the hydraulic oil, providing a powerful impact force for the breaker. The presence of the fixing ring 13 not only makes the connection between the high-pressure oil pipe 3 and the connecting pipe 12 more secure, able to withstand the impact and vibration of high-pressure hydraulic oil and prevent the oil pipe from falling off or loosening, but also effectively avoids hydraulic oil leakage, ensuring the normal operation of the hydraulic system.

[0034] Example 3:

[0035] Please see Figure 5 In order to provide a stable hydraulic oil source for the operation of the hydraulic breaker, a hydraulic storage tank 4 and an energy storage device 5 are installed.

[0036] A hydraulic storage tank 4 is clamped to the top of the high-pressure oil pipe 3, and an energy storage device 5 is clamped inside the main body 1. A delivery pipe 14 is fixedly installed on the top of the hydraulic storage tank 4, and a regulating valve 15 is clamped to the outer wall of the delivery pipe 14. A branch pipe 16 is fixedly installed on the energy storage device 5, and the bottom of the branch pipe 16 is threadedly connected to the top of the delivery pipe 14. A protective sleeve 17 is fitted onto the outer wall of the energy storage device 5, and a reinforcing ring 18 is welded to the top of the energy storage device 5. A flexible rubber tube 19 is threadedly connected to the top of the reinforcing ring 18. Therefore, the fixed installation of the delivery pipe 14 ensures the tightness and stability of its connection with the hydraulic storage tank 4, preventing leakage during hydraulic oil transmission. Leaks or loosening are observed. As a channel for hydraulic oil to flow out of the hydraulic storage tank 4, the delivery pipe 14 accurately delivers the hydraulic oil from the storage tank 4 to other components, such as the accumulator 5, ensuring the normal operation of the entire hydraulic system and the coordinated work between components. This provides a stable supply of hydraulic oil for the hydraulic breaker's pressurization and impact resistance function. By adjusting the regulating valve 15, the flow rate and pressure of hydraulic oil entering the accumulator 5 and the booster cylinder 2 can be precisely controlled, thereby achieving flexible adjustment of the hydraulic breaker's striking force and operating frequency. Through the branch pipe 16, the hydraulic oil from the storage tank 4 can be introduced into the accumulator 5 for storage and regulation. Simultaneously, the stored hydraulic oil is quickly released back into the hydraulic system when needed, achieving effective energy transfer and storage. The tight connection between branch pipe 16, accumulator 5, and delivery pipe 14 ensures smooth flow of hydraulic oil among the three, providing a reliable channel for accumulator 5 to perform its energy storage and buffering functions. The protective sleeve 17 provides a physical protective barrier for accumulator 5, preventing damage caused by external factors, extending its service life, and improving its operational reliability. Furthermore, the protective sleeve 17 reduces noise and vibration generated by accumulator 5 during operation, improving the working environment and further enhancing its performance. The performance and stability of the entire hydraulic breaker's pressurization and impact resistance device have been improved. The reinforcing ring 18 is firmly connected to the top of the accumulator 5 by welding, which enhances the structural strength of the top of the accumulator 5. It can withstand the pressure of the hydraulic oil inside the accumulator 5 and various impact forces that may be generated during operation, preventing the top of the accumulator 5 from deforming or being damaged due to excessive force. The soft rubber tube 19 provides a flexible connection method for the accumulator 5, which can be used to connect other auxiliary equipment or as a channel for exhaust, overflow, etc., further expanding the function and application range of the accumulator 5, while also ensuring the sealing and stability of the entire hydraulic system.

[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

[0038] In this invention, the working steps of the device are as follows:

[0039] First, the hydraulic oil in the hydraulic storage tank 4 enters the booster cylinder 2 through the high-pressure oil pipe 3. Under the action of the hydraulic oil, the booster cylinder 2 pressurizes the hydraulic oil through its internal booster mechanism, increasing the output hydraulic oil pressure. The pressure gauge 10 on the booster cylinder 2 can display the pressure value inside the cylinder in real time, so that the operator can adjust it according to actual needs. The accumulator 5 is connected to the delivery pipe 14 of the hydraulic storage tank 4 through the branch pipe 16. During the operation of the breaker, when the pressure and flow in the hydraulic system fluctuate, the accumulator 5 can store excess hydraulic oil and quickly release the stored hydraulic oil back into the hydraulic system when needed, increasing the instantaneous flow and pressure of the hydraulic system. To ensure the hydraulic breaker can continuously and stably output powerful impact force, when the hydraulic breaker is performing crushing operations, the impact and vibration forces generated are transmitted through the main body 1 to the buffer pad 7 at the bottom of the limit frame 6. The buffer pad 7 can effectively absorb and disperse these impact and vibration forces, preventing them from directly acting on other parts of the hydraulic breaker and the equipment connected to it, thereby protecting the equipment, reducing wear and extending its service life. The hydraulic oil pressurized by the booster cylinder 2 drives the crushing rod 9 at the bottom of the main body 1 to generate a powerful impact force to crush the material. The fixing frame 8 on one side of the main body 1 ensures that the hydraulic breaker can be stably installed on the external equipment, ensuring the accuracy and stability of the crushing operation.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
