Description

Technical Field

[0001] The invention relates to the technical field of outdoor crushing construction, and in particular to a noise reduction and protection visualization device for a crushing hammer. Background Art

[0002] Hydraulic breaker, also known as hydraulic breaker or hydraulic stone breaker, has become an important working tool of hydraulic excavator, which can more effectively clear floating stones and soil in rock crevices when excavating building foundations.

[0003] During operation, the drill rod of a current hydraulic breaker contacts the surface being treated. The impact force provided by the internal piston rod shatters the surface, thereby achieving the desired construction goal. However, the hydraulic breaker produces a high level of noise during operation, generating large amounts of dust and flying rocks as it breaks the surface. This can easily cause harm to surrounding personnel and equipment, increasing the risk of construction operations. Currently, some technicians install protective covers and other structures on the drill rod to reduce noise, dust, and flying rocks. However, these structures present problems: conventional protective covers struggle to coordinate effectively with the movement of the drill rod, easily forming gaps between the cover and the work surface, resulting in ineffective sound insulation. The cover is also susceptible to damage from impact during use. Furthermore, the protective cover blocks the operator's line of sight, making it difficult to observe and assess the condition of the work surface, impacting the efficiency and quality of construction operations.

[0004] Clearly, there's still room for improvement in the current handling of noise, dust, and flying rocks during hydraulic breaker operations. Optimization is needed to improve protection around the drill rod, reduce the impact of noise, dust, and flying rocks on the surrounding environment, and ensure sufficient visibility to improve operational efficiency. Therefore, a more reasonable technical solution is needed to address the technical issues currently encountered. Summary of the Invention

[0005] In order to overcome at least one of the defects mentioned above, the present invention proposes a noise reduction and protection visualization device for a breaker hammer, which aims to form a protective structure at the drill rod through the device, which can cooperate with the movement of the drill rod to maintain strict protection, improve the control of noise, dust and flying stones, and at the same time make it easier for operators to see the internal picture, thereby ensuring work efficiency and quality.

[0006] In order to achieve the above objectives, the visualization device disclosed in the present invention can adopt the following technical solutions: A noise reduction and protection visualization device for a breaker hammer comprises a connecting portion connected to a breaker hammer body, a movable cover body is arranged below the connecting portion, and the movable cover body comprises an upper cover body fixedly matched with the connecting portion, and a lower cover body slidably connected to the upper cover body; a visual monitoring component is arranged in the connecting portion, and the visual monitoring component is used to capture the image inside the movable cover body; a protective component for protecting the visual monitoring component is arranged at the connecting portion, and a cleaning component for cleaning dust inside the movable cover body is also provided.

[0007] The visualization device disclosed above is connected to the breaker hammer via a connecting portion. A movable cover is mounted over the drill rod, with the upper cover fixed relative to the drill rod and the lower cover movable relative to the drill rod. When the breaker hammer moves toward the construction surface, the lower cover first contacts the construction surface before the drill rod. As the drill rod continues to approach the construction surface, the upper and lower covers move relative to each other. During construction, the upper and lower covers always cover the construction site, preventing internal dust and impurities from escaping and also preventing flying rocks from flying out. At the same time, the movable cover can isolate noise within the movable cover to avoid affecting the surrounding environment.

[0008] Furthermore, the structure of the connection portion can take various forms and is not limited to a single one. Here, we optimize and propose one feasible option: the connection portion includes a connecting frame, the upper end of which is connected and fixed to the breaker body, and the lower end of the connecting frame forms a mounting cavity, and the visual monitoring assembly is disposed in the mounting cavity. When adopting this solution, the connecting frame is connected and fixed by holding the breaker body tightly.

[0009] Furthermore, the upper and lower housings can be configured in a variety of ways, and are not intended to be exclusive. Here, we propose an optimized and feasible option: the upper housing comprises a cylindrical barrel, and the lower housing is provided with a corresponding cylindrical barrel section. The cylindrical barrel and the cylindrical barrel section slide together via connecting rails. When adopting this solution, the cylindrical barrel and the cylindrical barrel section can be cylindrical or square.

[0010] Furthermore, the coordination of the upper and lower covers is subject to certain restrictions. Under normal conditions, the upper and lower covers maintain their maximum extension length. This can be achieved through a variety of solutions. Here, we optimize and propose one feasible option: an elastic push component is further provided between the upper and lower covers. The elastic push component applies an elastic recursive force to the lower cover, causing the lower and upper covers to slide relative to each other and extend to their maximum position. When adopting the above solution, the number of elastic push components is not unique; several can be provided at intervals to provide a uniform and stable elastic push force.

[0011] Furthermore, the elastic push assembly can be constructed in various forms, and its structure is not limited to a single form. Here, optimization is performed and one of the feasible options is proposed: the elastic push assembly includes guide grooves arranged at intervals on the side walls of the upper cover body, and guide rods are arranged in the guide grooves and are subjected to the elastic push force of the push spring. The guide rods are connected to the lower cover body and drive the lower cover body to slide in the longitudinal direction.

[0012] Furthermore, the elastic push assembly is easily contaminated with dust at the construction site, so it needs to be cleaned to maintain the elastic push force. This can be achieved in a variety of ways. Here, we optimize and propose one feasible option: the guide rod is provided with a dirt removal brush. The dirt removal brush is located at the lower end of the guide rod. When the lower cover slides toward the lower part of the upper cover, the dirt removal brush brushes impurities in the guide groove downward. When adopting the above solution, the dirt removal brush is located on the guide rod and removes dust and other impurities accumulated in the guide groove.

[0013] Furthermore, the protective assembly protects the visual monitoring assembly from dust or rocks. A variety of options are possible for this protective assembly, and its structure is not strictly limited. Here, we propose an optimized and feasible option: the protective assembly includes a transparent protective plate positioned within the mounting cavity. The plate covers the visual monitoring assembly and blocks dust and debris from the active body. When this solution is employed, the transparent protective plate can be made of high-strength PVC.

[0014] Furthermore, the cleaning assembly is used to actively clean the interior of the movable cover. Its structure is not limited to a single one. Here, an optimization is made and one feasible option is proposed: the cleaning assembly includes a dust collection assembly disposed on the lower cover, the dust collection assembly includes an air inlet disposed on one side of the lower cover and a dust collector disposed on the other side of the lower cover; the cleaning assembly also includes a spray assembly disposed on the upper cover, the spray assembly includes a plurality of spray heads for spraying water mist. When adopting the above solution, the spray assembly also includes a water pipe and a connected water pump and water tank for spraying water mist into the movable cover.

[0015] Furthermore, in order to reduce the noise impact on the surrounding environment, the inner wall of the upper cover and the lower cover is provided with a sound-absorbing layer. When adopting the above solution, the sound-absorbing layer can be made of sound-absorbing foam.

[0016] Furthermore, in order to enhance the sealing performance, a dustproof sealing ring is provided at the lower end of the upper cover body to seal the annular gap formed between the upper cover body and the lower cover body. When the above solution is adopted, the dustproof sealing ring can be a rubber ring.

[0017] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in the present invention include: The present invention provides a visualization device, and the movable cover cooperates with the action of the breaker hammer to better fit the construction surface, forming a sufficient coverage of the construction surface, and well controlling the noise, dust and flying stones generated by the construction, thereby keeping the construction surface clean and quiet, reducing safety hazards, and providing a visual picture, which makes it convenient for operators to understand the actual situation of the construction location, thereby ensuring construction efficiency and quality.

[0022] This embodiment will be further explained below with reference to the accompanying drawings and specific examples.

[0023] In view of the noise, dust, flying stones and other phenomena existing in the breaker hammer construction in the prior art, the following embodiments are optimized and overcome the defects existing in the prior art.

[0024] Example like Figure 1 、 Figure 2As shown, this embodiment provides a noise reduction and protection visualization device for a breaker hammer, including a connecting part 1 connected to the breaker hammer body 8, a movable cover body is provided below the connecting part 1, and the movable cover body includes an upper cover body 2 fixedly matched with the connecting part 1, and a lower cover body 4 slidingly connected to the upper cover body 2; a visual monitoring component 10 is provided in the connecting part 1, and the visual monitoring component 10 is used to capture the image inside the movable cover body; a protective component for protecting the visual monitoring component 10 is provided at the connecting part 1, and a cleaning component for cleaning dust inside the movable cover body is also provided.

[0025] The visualization device disclosed in this embodiment is connected to the breaker hammer through the connection part 1. The movable cover body is sleeved on the outside of the drill rod 9, and the upper cover body 2 is fixed relative to the drill rod 9, and the lower cover body 4 is movable relative to the drill rod 9. When the breaker hammer moves toward the construction surface, the lower cover body 4 first contacts the construction surface. At this time, the drill rod 9 has not yet contacted the construction surface. When the drill rod 9 continues to approach the construction surface, the upper cover body 2 and the lower cover body 4 move relative to each other. During the construction process, the upper cover body 2 and the lower cover body 4 always cover the construction site, preventing internal dust and impurities from escaping outward, and also preventing flying rocks from flying outward. At the same time, the movable cover body can isolate noise within the movable cover body to avoid affecting the surrounding environment.

[0026] The structure of the connecting portion 1 can take various forms and is not limited to a single one. This embodiment optimizes and adopts one feasible option: the connecting portion 1 includes a connecting frame, the upper end of which is connected and fixed to the breaker body 8, and the lower end of which forms a mounting cavity 101. The visual monitoring assembly 10 is disposed in the mounting cavity 101. When adopting the above solution, the connecting frame is connected and fixed by holding the breaker body 8.

[0027] The upper cover 2 and lower cover 4 can be configured in a variety of ways, and are not intended to be limited to a single configuration. This embodiment optimizes and employs one feasible option: the upper cover 2 comprises a cylindrical barrel, and the lower cover 4 is correspondingly provided with a cylindrical barrel section 401. The cylindrical barrel and cylindrical barrel section 401 are slidably engaged via connecting slide rails. When this configuration is employed, the cylindrical barrel and cylindrical barrel section 401 can be cylindrical or square.

[0028] Preferably, a conical barrel section 402 is further connected to the bottom of the cylindrical barrel section 401 .

[0029] The coordination of the upper cover 2 and the lower cover 4 is subject to certain restrictions. Under normal conditions, the upper cover 2 and the lower cover 4 maintain their maximum extension length. This can be achieved through a variety of solutions. This embodiment optimizes and adopts one feasible option: an elastic push component is further provided between the upper cover 2 and the lower cover 4. The elastic push component applies an elastic recursive force to the lower cover 4, causing the lower cover 4 and the upper cover 2 to slide relative to each other and extend to the maximum position. When adopting the above solution, the number of elastic push components is not limited; several can be provided at intervals to provide a uniform and stable elastic push force.

[0030] The elastic push assembly can be constructed in various forms, and its structure is not limited to a single form. This embodiment is optimized and adopts one of the feasible options: the elastic push assembly includes guide grooves 201 arranged at intervals on the side walls of the upper cover body 2, and a guide rod 203 is provided in the guide groove 201 and is subjected to the elastic push force of the push spring 202. The guide rod 203 is connected to the lower cover body 4 and drives the lower cover body 4 to slide in the longitudinal direction.

[0031] The elastic push assembly is easily contaminated with dust at the construction site, so it needs to be cleaned to maintain the elastic push force. This can be achieved in a variety of ways. This embodiment optimizes and adopts one feasible option: the guide rod 203 is provided with a dirt removal brush 204. The dirt removal brush 204 is located at the lower end of the guide rod 203. When the lower cover 4 slides toward the lower part of the upper cover 2, the dirt removal brush 204 brushes impurities in the guide groove 201 downward. When adopting the above solution, the dirt removal brush 204 is located on the guide rod 203 and removes dust and other impurities accumulated in the guide groove 201.

[0032] The protective assembly protects the visual monitoring assembly from dust or rocks. Various options are available for the protective assembly, and their structure is not strictly limited. This embodiment optimizes and adopts one feasible option: the protective assembly includes a transparent protective plate 102 positioned within the mounting cavity 101. This plate covers the visual monitoring assembly and blocks dust and debris from the active body. When this solution is used, the transparent protective plate 102 can be made of high-strength PVC.

[0033] Preferably, in this embodiment, a flip plate is provided in the installation cavity 101, which is used to carry the visual monitoring component and drive the visual monitoring component. Under the action of the flip plate, the visual monitoring component can be flipped to the working position and the idle position. When flipped to the working position, the visual monitoring component faces the movable cover and is used to capture the image. When flipped to the idle position, the visual monitoring component is retracted into the installation cavity 101 for protection.

[0034] In some other embodiments, the visual monitoring component may also include a camera body and a mesh protection net. The mesh protection net is installed in front of the camera objective lens and is made of a high-strength, impact-resistant material, such as a high-strength metal alloy or special engineering plastic, which can effectively resist the impact of flying gravel. The mesh size of the mesh protection net is precisely designed to block gravel without significantly affecting the imaging quality of the camera. In terms of the imaging principle, the pinhole imaging principle is used to ensure the camera's visual function. Pinhole imaging is an imaging method based on the principle of linear propagation of light. When light passes through a small hole, an inverted real image is formed on the other side of the hole. The mesh of the mesh protection net is equivalent to a small hole. After passing through the mesh, the light enters the camera objective lens and forms a clear image. By rationally designing the size and distribution of the mesh, it can be ensured that the imaging quality meets the actual monitoring needs.

[0035] The cleaning assembly is used to actively clean the interior of the movable cover. Its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the cleaning assembly includes a dust collection assembly disposed on the lower cover 4, the dust collection assembly including an air inlet 6 disposed on one side of the lower cover 4 and a dust collector 7 disposed on the other side of the lower cover 4; the cleaning assembly also includes a spray assembly disposed on the upper cover 2, the spray assembly including a plurality of spray heads 5 for spraying water mist. When adopting the above solution, the spray assembly also includes a water pipe and a connected water pump and water tank for spraying water mist into the movable cover.

[0036] In order to reduce the noise impact on the surrounding environment, the inner wall surfaces of the upper cover 2 and the lower cover 4 are provided with a sound absorbing layer 11. When the above solution is adopted, the sound absorbing layer 11 can be made of sound absorbing foam.

[0037] In order to enhance the sealing performance, a dustproof sealing ring 3 is further provided at the lower end of the upper cover 2 to seal the annular gap formed between the upper cover 2 and the lower cover 4. When the above solution is adopted, the dustproof sealing ring 3 can be a rubber ring.

[0038] The above are the implementation methods listed in this embodiment, but this embodiment is not limited to the above optional implementation methods. Those skilled in the art can arbitrarily combine the above methods to obtain other various implementation methods. Anyone can derive other various implementation methods based on the inspiration of this embodiment. The above specific implementation methods should not be understood as limiting the scope of protection of this embodiment. The scope of protection of this embodiment should be based on the definition in the claims.
