Description

Technical Field

[0001] This application relates to the field of cleaning technology for abruptly expanded cylindrical components, and in particular to a high-pressure cleaning structure for supporting abruptly expanded cylindrical components. Background Technology

[0002] Protruding cylindrical components are commonly used parts in machinery, fluid transport equipment, pressure vessels, and industrial pipeline components. Their unique structure, combining a cylindrical body with a protruding section, makes them prone to accumulating dirt, impurities, and stubborn residues during use. This is especially true in precision machining or complex operating conditions, where the need for cleanliness is even more urgent. This invention is designed to address the cleaning challenges of such parts, aiming to overcome the bottlenecks of traditional cleaning technologies and provide a highly adaptable, safe, and efficient cleaning solution, thereby promoting the upgrading of cleaning technologies in related industrial fields.

[0003] In related technologies, the traditional cleaning of abruptly expanding cylindrical parts mainly adopts two types of solutions: one is to use general-purpose cleaning equipment to flush the parts with fluids through conventional methods such as spraying and soaking, relying on chemical solvents or simple mechanical force to remove dirt; the other is to use manual hand tools to wipe and clean the inside of the parts, specifically treating the residue in the abruptly expanding parts. These two solutions have been applied to some extent in the cleaning of cylindrical parts with simple structures.

[0004] Regarding the aforementioned technologies, traditional cleaning solutions for the complex structure of abruptly expanded cylindrical components have several shortcomings. First, general-purpose cleaning equipment lacks targeted design and cannot cover cleaning blind spots such as the connection between the abruptly expanded part and the cylindrical body, making it difficult to thoroughly remove dirt. Second, the equipment lacks adaptability and cannot flexibly adapt to abruptly expanded cylindrical components of different specifications and shapes, limiting its applicability. Third, the cleaning process requires a large amount of manual intervention, which is cumbersome, costly, and inefficient, and manual operation can easily damage the surface of the parts. In addition, traditional cleaning equipment mostly uses an electrically driven structure, which is prone to safety risks due to electric sparks, leakage, etc., in industrial environments with dust, corrosive media, or special safety requirements. It cannot meet relevant safety standards and is difficult to adapt to the needs of modern industrial production for efficient, precise, and automated cleaning. Summary of the Invention

[0005] To improve the cleaning effect of blind spot dirt in a protruding cylindrical component, this application provides a high-pressure cleaning structure for supporting a protruding cylindrical component.

[0006] A high-pressure cleaning structure for supporting a sudden expansion type cylindrical component includes: The positioning support is provided with a multi-stage support link. The multi-stage support link has a switchable first-stage deployment state and a second-stage deployment state. The first-stage deployment state is used to adapt to the inner wall support of the cylindrical component, and the second-stage deployment state is used to adapt to the protruding inner wall of the cylindrical component. An elastic rolling part is disposed on the positioning support part for rolling contact with the protruding cylindrical part, and the elastic rolling part is made of elastic resin material; The high-pressure cleaning unit is equipped with a cleaning nozzle. The high-pressure cleaning unit is connected to an external high-pressure water pipe to receive high-pressure water flow and spray it from the cleaning nozzle onto the inner wall of the bulging cylindrical component. The positioning support is provided on the outer wall of the high-pressure cleaning unit to keep the high-pressure cleaning unit and the bulging cylindrical component concentric.

[0007] By adopting the above technical solution, the positioning support unit uses the elastic deformation energy of the elastic rolling part to adjust the multi-stage support linkage to the second-stage unfolding state that adapts to the inner wall of the protruding cylindrical part, so as to adapt to the support distance when the cylindrical part has a protruding inner wall. At the same time, the high-pressure cleaning unit provides a uniform circumferential high-pressure water flow, so that the high-pressure cleaning unit maintains the central position during the cleaning process of the protruding cylindrical part, thereby reducing the decrease in cleaning uniformity caused by eccentricity and helping to improve the dirt cleaning effect in blind areas.

[0008] Optionally, the positioning support portion is further provided with: The cleaning connector has multiple locking parts evenly arranged along its periphery. The number of locking parts corresponds to the number of multi-stage support rods and is used to fix it to one end of the multi-stage support rods. An elastic self-locking component is provided on the multi-stage support link for adjusting the switching of the multi-stage support link from the first-stage deployment state to the second-stage deployment state.

[0009] By adopting the above technical solution, the elastic self-locking component is designed to enable the multi-stage support linkage to stably self-lock when switching to the second-stage deployment state or the first-stage deployment state.

[0010] Optionally, the multi-stage support link includes a first connecting rod and a second connecting rod, one end of the first connecting rod is detachably fixed to the locking part, and the other end of the first connecting rod is hinged to one end of the second connecting rod; When in the first-level unfolded state, the first connecting rod and the second connecting rod are inclined together. When in the second-level unfolded state, the angle between the first connecting rod and the second connecting rod increases until they are unfolded to be parallel to each other.

[0011] By adopting the above technical solution, the first connecting rod and the second connecting rod cooperate with each other. The first connecting rod provides a first-level unfolding fixation, thereby forming a second-level unfolding state where the second connecting rod and one end of the first connecting rod can be hinged and rotated to achieve the abutment support adaptation to the protruding inner wall, which facilitates uniform inner wall cleaning by the high-pressure cleaning unit.

[0012] Optionally, the elastic rolling part includes a limiting roller and a moving roller. The limiting roller is disposed on the parallel side wall of the end of the first connecting rod near the second connecting rod, and the moving roller is disposed on the end of the second connecting rod away from the first connecting rod. When switched to the secondary unfolding state, the moving roller abuts against the inner wall of the protruding cylindrical member.

[0013] By adopting the above technical solution, the limiting roller and the moving roller work together. The moving roller provides basic rolling contact to maintain a certain support force. At the same time, the contact and compression between the limiting roller and the inner wall of the protrusion triggers the automatic switching of the secondary expansion state, which helps to improve the timeliness of support adjustment. At the same time, it does not require control by electronic components, which helps to reduce the risk of electricity use.

[0014] Optionally, the elastic self-locking component includes a limiting component and a snap-fit ​​component. The snap-fit ​​component is fixedly connected to the first connecting rod and the second connecting rod. When in the first-level unfolded state, the snap-fit ​​component is elastically snapped into the limiting component. When the limiting roller is squeezed, the squeezing force forces the snap-fit ​​component to compress downward and disengage from the limiting component. The snap-fit ​​component separates from the limiting component, and the second connecting rod switches to the second-level unfolded state with the first connecting rod.

[0015] By adopting the above technical solution, the limiting component and the snap-fit ​​component cooperate with each other. When the limiting roller is squeezed, the snap-fit ​​component and the limiting component can snap-fit ​​with each other to limit the movement, thereby keeping the first connecting rod and the second connecting rod parallel to unfold, so as to accommodate a larger protruding inner wall diameter.

[0016] Optionally, the high-pressure cleaning unit includes a cleaning nozzle and a cleaning tip. One end of the cleaning nozzle has a threaded adapter, which is detachably threaded to the cleaning connector. The cleaning tip is located around the cleaning nozzle and is connected to the interior of the cleaning nozzle.

[0017] By adopting the above technical solution, the cleaning nozzle and the cleaning spray head cooperate with each other and are detachably connected by the cleaning nozzle and the cleaning connector, which facilitates quick disassembly and installation. The high-pressure water flow is sprayed out in all directions by circumferential cleaning nozzles to clean the dirt on the inner wall.

[0018] Optionally, the axis of the cleaning nozzle is inclined to the axis of the cleaning head, and when the cleaning nozzle receives high-pressure water flow to clean the protruding cylindrical component, it provides a counter-thrust force to drive the cleaning head to move.

[0019] By adopting the above technical solution and setting the cleaning nozzles with an inclined orientation, the cleaning nozzles can provide the high-pressure water flow required for cleaning the dirt on the inner wall. At the same time, they can generate the thrust required for movement to drive the entire high-pressure cleaning unit to move. There is no need to configure additional motors and other control components to control the movement, thus improving the safety of the working environment.

[0020] Optionally, multiple cleaning nozzles are provided, and the multiple cleaning nozzles are evenly arranged circumferentially along the axis of the cleaning nozzle.

[0021] By adopting the above technical solution, the arrangement of multiple cleaning nozzles enables the inner wall of the cylindrical component to receive effective cleaning water flow, improves the uniformity of water flow rinsing, and helps to further enhance the dirt removal capability.

[0022] Optionally, the multi-stage support rods are provided in at least three sets, and the three sets of multi-stage support rods are evenly arranged along the circumference of the high-pressure cleaning section.

[0023] By adopting the above technical solution, the setting of at least three sets of multi-stage support rods enables the high-pressure cleaning section to form a triaxial center, which has a better and more robust support effect compared to arranging only two sets of multi-stage support rods.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The positioning support unit uses the elastic deformation energy of the elastic rolling part to adjust the multi-stage support linkage to the secondary unfolding state that adapts to the inner wall of the protruding cylindrical part, so as to adapt to the support distance when the cylindrical part has a protruding inner wall. At the same time, the high-pressure cleaning unit provides a uniform circumferential high-pressure water flow, so that the high-pressure cleaning unit maintains the center position during the cleaning process of the protruding cylindrical part, thereby reducing the decrease in cleaning uniformity caused by eccentricity and helping to improve the dirt cleaning effect in blind areas. 2. The limiting component and the snap-fit ​​component cooperate with each other. When the limiting roller is squeezed, the snap-fit ​​component and the limiting component can snap together to limit the movement, so that the first connecting rod and the second connecting rod remain parallel and unfolded to accommodate a larger protruding inner wall diameter. 3. The limiting roller and the moving roller work together. The moving roller provides basic rolling contact to maintain a certain support force. At the same time, the contact and compression between the limiting roller and the inner wall of the protrusion triggers the automatic switching of the secondary expansion state, which helps to improve the timeliness of support adjustment. At the same time, it does not require control by electronic components, which helps to reduce the risk of electricity use. Attached Figure Description

[0031] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1-5 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0032] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0033] This application discloses a high-pressure cleaning structure for supporting a protruding cylindrical component. The positioning support 1 uses the elastic deformation energy of the elastic rolling part 2-7 to adjust the multi-stage support link 2-1 to a two-stage unfolded state that adapts to the inner wall of the protruding cylindrical component, so as to adapt to the support distance when the cylindrical component has a protruding inner wall. At the same time, the high-pressure cleaning part 2 provides a uniform circumferential high-pressure cleaning water flow, so that the high-pressure cleaning part 2 maintains a central position during the cleaning process of the protruding cylindrical component, thereby reducing the decrease in cleaning uniformity caused by eccentricity and helping to improve the dirt cleaning effect in blind areas.

[0034] Reference Figure 1 and Figure 2A high-pressure cleaning structure for supporting a sudden expansion cylindrical component includes: a positioning support part 1, an elastic rolling part 2-7, and a high-pressure cleaning part 2. The positioning support part 1 has multiple supporting connecting rods 2-1 arranged around its periphery. At least three sets of these multi-stage supporting connecting rods 2-1 are provided; this embodiment uses three sets as an example. The three sets of multi-stage supporting connecting rods 2-1 are spaced apart around the positioning support part 1, forming a triaxial centering. The elastic rolling part 2-7 is located at the end of the multi-stage supporting connecting rods 2-1 and is used to roll against the inner wall of the cylindrical component to facilitate movement within the cylindrical component.

[0035] Specifically, it should be further explained that the elastic rolling part 2-7 includes a limiting roller 2-5 and a moving roller 2-6. The limiting roller 2-5 is disposed on the parallel side wall of the end of the first connecting rod near the second connecting rod, and the moving roller 2-6 is disposed on the end of the second connecting rod away from the first connecting rod. When switched to the second-stage unfolding state, the moving roller 2-6 abuts against the inner wall of the protruding cylindrical part.

[0036] Reference Figures 1-3 The high-pressure cleaning unit 2 is fixedly connected to the positioning support unit 1 via a threaded connection. The high-pressure cleaning unit 2 includes a cleaning nozzle 3-1 and a cleaning nozzle 3-3. One end of the cleaning nozzle 3-1 is provided with a threaded adapter 3-2, which is detachably threadedly connected to the cleaning connector 2-3. The cleaning nozzle 3-3 is located on the periphery of the cleaning nozzle 3-1 and is connected to the inside of the cleaning nozzle 3-1.

[0037] It should be further explained that a rotating connection is formed between the cleaning head 3-1 and the cleaning nozzle 3-3, allowing the cleaning nozzle 3-3 to rotate circumferentially. This provides a rotating spray of water when cleaning the inner wall of the cylindrical component, thus improving the cleaning effect. Furthermore, the axis of the cleaning nozzle 3-3 is inclined to the axis of the cleaning head 3-1. When the cleaning nozzle 3-3 receives high-pressure water and cleans the protruding cylindrical component, it provides an inclined thrust that drives the cleaning head 3-1 to move. Multiple cleaning nozzles 3-3 are provided; this embodiment uses three as an example. The three nozzles are evenly spaced circumferentially to increase the amount of water flowing during cleaning and improve cleaning efficiency.

[0038] Reference Figure 2 The multi-stage support link 2-1 includes a first connecting rod and a second connecting rod. One end of the first connecting rod is detachably fixed to the locking part 2-2, and the other end of the first connecting rod is hinged to one end of the second connecting rod. In the first-stage unfolded state, the first connecting rod and the second connecting rod are inclined together. In the second-stage unfolded state, the angle between the first connecting rod and the second connecting rod increases until they are unfolded to be parallel to each other.

[0039] Reference Figure 2 and Figure 4 , Figure 5 The elastic self-locking component 2-4 includes a limiting component 2-4-1 and a locking component 2-4-2. The locking component 2-4-2 is fixedly connected to the first connecting rod and the second connecting rod. When in the first-level unfolded state, the locking component 2-4-2 is elastically locked to the limiting component 2-4-1. When the limiting roller 2-5 is squeezed, the squeezing force forces the locking component 2-4-2 to compress downward and disengage from the limiting component 2-4-1. The locking component 2-4-2 separates from the limiting component 2-4-1, and the second connecting rod switches to the second-level unfolded state with the first connecting rod.

[0040] During operation, the first-level unfolded state is used to adapt to the inner wall support of the cylindrical component, and the second-level unfolded state is used to adapt to the protruding inner wall of the cylindrical component. Specifically, when the multi-level support linkage 2-1 of the mechanism is in the first-level unfolded state, the elastic self-locking component 2-4 is triggered at the small diameter. When it enters the protruding expansion position, the elastic self-locking component 2-4 opens, the multi-level support linkage 2-1 opens, and the moving resin roller moves after it adheres to the inner wall.

[0041] Reference Figure 2 The positioning support part 1 is also provided with a cleaning connector 2-3 and an elastic self-locking member 2-4. The cleaning connector 2-3 has multiple locking parts 2-2 evenly arranged along its circumference, the number of which corresponds to the number of multi-stage support rods 2-1, for fixed connection to one end of the multi-stage support rods 2-1. The elastic self-locking member 2-4 is disposed on the multi-stage support rods 2-1 and is used to adjust the switching between the first-stage and second-stage deployment states of the multi-stage support rods 2-1. It includes a limiting member 2-4-1 and a locking member 2-4-2. In the initial state, the limiting member 2-4-1 and the locking member 2-4-2 are locked. At the small diameter, the resin roller has a certain elastic force. By squeezing the limiting resin roller, the elastic force is applied to loosen the locking member 2-4-2 and the limiting member 2-4-1, thus releasing the lock.
