Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for the inner wall of silicone hoses used in automobiles, and in particular to a hose inner wall cleaning device. Background Technology

[0002] In the automotive hose manufacturing industry, the problem of residual rubber fragments inside the hoses poses a significant safety hazard to subsequent vehicle operation and has become a key production pain point that the industry needs to address. As critical connecting components for core parts such as engines, automotive hoses are prone to generating and retaining fine rubber fragments inside the hose cavity during cutting, forming, and fluidization processes. If these residual rubber fragments are not thoroughly cleaned before leaving the factory, they can cause serious malfunctions after the hoses are installed and put into use due to the special operating conditions of the engine. Currently, the mainstream solution in the industry is a high-speed fan cleaning method, which involves introducing a high-speed airflow into the hose and using the impact force of the airflow to blow out the fine rubber fragments from the cavity. However, this cleaning solution has significant technical flaws and cannot meet the high-precision and high-reliability processing requirements of automotive hoses. On the one hand, the high-speed airflow has limited effectiveness in cleaning fine rubber fragments in hidden locations inside the hose, such as bends and dead corners inside joints. The airflow is prone to forming eddies in these areas, which cannot generate effective impact force, resulting in some rubber fragments still adhering to the inner wall of the hose cavity, and the cleaning is incomplete. On the other hand, the impact force of the high-speed airflow is difficult to control precisely. If the impact force is too small, it will not be able to peel off stubborn residual rubber fragments. If the impact force is too large, it may damage the inner wall of the hose, destroy the structural integrity of the hose, and affect the service life and sealing performance of the hose. Summary of the Invention

[0003] The technical problem to be solved by this utility model is that the high-pressure blower currently used for cleaning the inner wall of pipes has the defects of incomplete cleaning and damage to the pipes.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a hose inner wall cleaning device, including a frame, a connecting rod installed at the top of the frame and a mounting ring horizontally rotatably installed in the middle of the frame. The bottom of the mounting ring is provided with a fixing clamp for holding the hose. The top of the connecting rod is connected to a water supply pipe. The bottom of the connecting rod is provided with a water groove communicating with the water supply pipe. The bottom of the connecting rod is fixed with a pull rope, and the bottom of the pull rope is connected to a counterweight ball.

[0005] Preferably, a first mounting bracket and a second mounting bracket are fixed to the middle and top of the upright frame, respectively. A fixing ring is fixedly connected to the movable end of the first mounting bracket, and the mounting ring is coaxially rotatably connected to the fixing ring. The middle part of the connecting rod is hinged to the second mounting bracket.

[0006] Preferably, a drive motor is fixed on the first mounting bracket, and a drive gear is fixedly connected to the output end of the drive motor. A driven gear ring is coaxially fitted on the outer wall of the mounting ring. The drive gear meshes with the driven gear ring, and a slot is provided on the outer wall of the fixed ring for the drive gear to extend into.

[0007] Preferably, both ends of the outer wall of the mounting ring are coaxially fixedly fitted with connecting rings, and the inner wall of the fixing ring is provided with an annular protrusion. The annular protrusion is located between the two connecting rings, and the top and bottom ends of the annular protrusion are respectively attached to the bottom of the top connecting ring and the top of the bottom connecting ring.

[0008] Preferably, an electric pull rod is hinged between the second mounting bracket and the top of the connecting rod.

[0009] Preferably, connectors are fixedly connected to both sides of the bottom of the mounting ring, and the fixing clip is installed at the bottom end of the connector.

[0010] Preferably, the pull rope is in a traction state and is located at the inner edge of the mounting ring.

[0011] This utility model provides a hose inner wall cleaning device, which has the following beneficial effects.

[0012] This equipment, through a combination of water supply pipe and counterweight ball traction rope design, breaks the limitations of traditional high-speed fans that rely on airflow impact. The water supply pipe can deliver cleaning medium to the inner wall of the hose. With the counterweight ball traction rope, as the hose rotates with the installation ring, it can form physical friction and medium flushing in areas that are difficult for airflow to reach, such as bends and dead corners inside joints. This effectively removes stubborn residual rubber and avoids local residue. Compared with the shortcomings of high-speed fans in cleaning dead corners, it greatly improves the rubber cleaning rate and ensures that the turbocharger system will not be damaged by carbonization of residual rubber after the hose is installed.

[0016] like Figure 1 and Figure 2 As shown, this utility model provides a hose inner wall cleaning device, including a frame 1, a connecting rod 10 installed at the top of the frame 1, and a mounting ring 9 horizontally rotatably installed in the middle of the frame 1. The bottom of the mounting ring 9 is provided with a fixing clamp 7 for holding the hose. The top of the connecting rod 10 is connected to a water supply pipe 11. The bottom of the connecting rod 10 is provided with a water groove 12 communicating with the water supply pipe 11. The bottom end of the connecting rod 10 is fixed with a pull rope 13, and the bottom end of the pull rope 13 is connected to a counterweight ball 14.

[0017] During the internal cleaning of the hose, two clamps 7 are used to hold the top of the hose vertically. Then, a counterweight ball 14 is inserted from the top of the hose, which drives the pull rope 13 through the hose. The water supply pipe 11 is turned on, and water is supplied through the water tank 12. The water flows along the pull rope 13, and the installation ring 9 is rotated. During the rotation of the installation ring 9, the inside of the hose is cleaned by the pull rope 13 and the water flow, thus ensuring the quality of the internal cleaning of the hose. After the hose is cleaned once, the other end of the hose is clamped and cleaned again in the same way.

[0018] like Figure 1 As shown. A first mounting bracket 2 and a second mounting bracket 3 are fixed to the middle and top of the upright frame 1, respectively. A fixing ring 5 is fixedly connected to the movable end of the first mounting bracket 2. The mounting ring 9 is coaxially rotatably connected within the fixing ring 5. The connecting rod 10 is hinged to the second mounting bracket 3 at its middle. By secretly rotating the first mounting bracket 2 and the second mounting bracket 3 at the middle and top of the upright frame 1, the pull rope 13 and the mounting ring 9 are installed. The pull rope 13 is located directly above the mounting ring 9, which prevents the pull rope 13 from damaging the rubber tube.

[0019] like Figure 1 As shown. A drive motor 4 is fixed on the first mounting bracket 2. A drive gear 8 is fixedly connected to the output end of the drive motor 4. A driven gear ring 92 is coaxially fitted on the outer wall of the mounting ring 9. The drive gear 8 meshes with the driven gear ring 92, and a slot is provided on the outer wall of the fixing ring 5 for the drive gear 8 to extend into. When the drive motor 4 is started, the drive gear 8 rotates. The rotation of the drive gear 8 drives the driven gear ring 92 to rotate, which in turn drives the mounting ring 9 to rotate, thereby causing the rubber tube clamped below the mounting ring 9 to rotate.

[0020] like Figure 1 and Figure 2As shown. Both ends of the outer wall of the mounting ring 9 are coaxially fixedly fitted with connecting rings 91. The inner wall of the fixing ring 5 is provided with an annular protrusion, which is located between the two connecting rings 91. The top and bottom ends of the annular protrusion respectively fit against the bottom of the top connecting ring 91 and the top of the bottom connecting ring 91. First, the mounting ring 9 is rotated and installed inside the fixing ring 5. Then, the two connecting rings 91 are welded together. The vertical positioning of the mounting ring 9 is achieved through the cooperation between the annular protrusion inside the fixing ring 5 and the connecting rings 91.

[0021] like Figure 1 As shown. An electric pull rod 15 is hinged between the second mounting bracket 3 and the top of the connecting rod 10. By controlling the extension and retraction of the electric pull rod 15, the angle of the connecting rod 10 is adjusted, thereby moving the position of the pull rope 13 to accommodate different sizes of hoses.

[0022] like Figure 1 As shown, to ensure that the clamped tubing rotates along with the mounting ring 9 during rotation, connectors 6 are fixedly connected to both sides of the bottom of the mounting ring 9, and the fixing clips 7 are installed at the bottom ends of the connectors 6.

[0023] like Figure 1 As shown, to ensure that the pull rope 13 accurately cleans the inner wall of the clamped hose, the pull rope 13 is in a traction state and is located at the inner edge of the mounting ring 9.
