Technical Field
[0001] This utility model relates to the field of polishing and rust removal technology for tee elbows, and more specifically, to a rust removal device for the inside of a tee elbow. Background Technology
[0002] A tee elbow is a pipe fitting used for connecting pipes. It is typically made of materials such as cast iron, stainless steel, or plastic. A tee elbow has three connections: two in a straight line and the third at an angle, commonly 90 degrees or 45 degrees. It is mainly used to change the direction of pipes and to branch pipe connections, enabling piping systems to be laid out and fluid transported according to design requirements. It is widely used in various piping systems such as water supply and drainage, gas, heating, and chemical industries.
[0003] Publication No. (CN220498690U) discloses a polishing device for tee elbows, including a base. A groove is provided on one side of the base, and a motor is fixedly connected inside the groove. A threaded rod is fixedly connected to the output end of the motor, and a moving block is threadedly connected to the outside of the threaded rod. A sliding plate is fixedly connected to the upper part of the moving block, and a fixing plate is fixedly connected to the upper left part of the base. Positioning seats are fixedly connected to the upper parts of both the sliding plate and the fixing plate. This invention effectively fixes the elbow body, facilitating polishing of tee elbows of different specifications and preventing the elbow body from falling off during polishing, thus improving processing stability. Furthermore, it can effectively polish both the exterior and interior of the tee elbow, making the surface and interior of the tee elbow smoother and cleaner, thereby improving its quality.
[0004] However, this polishing device for tee elbows has the following drawbacks: the elbow is fixed by a positioning block, but the positioning block itself cannot be adjusted to suit elbows of different specifications. It can only position and maintain a stable effect for a single specification of elbow. At the same time, it cannot rotate or move up and down after fixing to guide the tee elbow to the grinding wheel and perform precise grinding and rust removal. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rust removal device for the inside of a tee elbow, so as to solve the problem that the prior art cannot achieve stable fixing of the tee elbow, while realizing angle adjustment and up-and-down movement of the elbow.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rust removal device for the inside of a tee elbow, comprising...
[0007] A base is provided, with an outer shell fixedly connected to the outside of the base. A hydraulic cylinder is also fixedly connected to the outside of the base. A fixed disk is fixedly connected to the drive end of the hydraulic cylinder. A rotating disk is rotatably connected to the outside of the fixed disk. A movable rod is movably connected to the inner wall of the rotating disk. A locking block is fixedly connected to the outside of the movable rod. A top block is movably connected to the outside of the movable rod. Multiple locking plates are fixedly connected to the inner wall of the rotating disk. Two push blocks are slidably connected to the inner wall of the rotating disk. Gaskets are fixedly connected to the outside of each push block. A moving block is fixedly connected to the outside of each push block. A spring is fixedly connected to the inner wall of the moving block. An adjustment assembly for adjusting subsequent components is slidably connected to the inner wall of the rotating disk.
[0008] The adjusting assembly includes a pressure plate, which is slidably connected to the inner wall of the rotating disk. A locking pin is fixedly connected to the inner wall of the pressure plate, and a spring is sleeved on the outside of the locking pin. Multiple slots are provided on the outside of the fixed disk.
[0009] A grinding wheel is movably connected to the outside of the housing, and a vacuum tube is fixedly connected to the inner wall of the housing.
[0010] The second spring is fixedly connected to the outside of the pressure plate, and the end of the second spring away from the pressure plate is fixedly connected to the inner wall of the rotating disk.
[0011] The locking pin is externally slidably connected to the inner wall of the rotating disk, and externally movably connected to the inner wall of the slot.
[0012] The card block is externally slidably connected to the inner wall of the rotating disk, and externally movably connected to the outside of the card plate.
[0013] The top block is slidably connected to the inner wall of the rotating disk, and the outside of the top block is in contact with the outside of the moving block.
[0014] The movable block is externally slidably connected to the inner wall of the rotating disk, and one end of the spring away from the movable block is fixedly connected to the inner wall of the rotating disk.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In the above solution, by placing the tee elbow above the rotating disk, pushing the movable rod causes the top block to press against the moving block. The moving block is deformed by a spring to allow the top block to enter, while simultaneously driving the push block to move and lock the tee elbow. The push block is fixed by a gasket to avoid rigid collision and increase friction. Rotating the movable rod causes the locking block to lock outside the locking plate, improving the fixing stability.
[0017] In the above solution, by setting an adjustment component, when adjusting the angle, pulling up the locking pin causes the pressure plate connected to it to squeeze the second spring, causing the locking pin to disengage from the slot of the fixed plate, allowing the rotating plate to rotate; after reaching the appropriate position, releasing the locking pin causes the second spring to rebound, and the locking pin to re-engage into the slot for fixation. Then, starting the cylinder pushes the grinding wheel into the T-junction elbow, while the motor drives the grinding wheel to rotate, and the dust suction pipe is turned on to remove the dust, completing precise rust removal.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0024] As attached Figure 1 To be continued Figure 3 An embodiment of this utility model provides a rust removal device for the interior of a tee elbow, including...
[0025] Base 1 serves as the fundamental support structure for the entire rust removal device, providing a reliable support platform for installation and stable operation. An outer shell 2 is fixedly connected to the outside of base 1. The outer shell 2 surrounds the base 1, protecting the internal structure and maintaining the overall appearance of the device, preventing internal components from being damaged by external impacts. A hydraulic cylinder 3 is also fixedly connected to the outside of base 1. The hydraulic cylinder 3 provides power output, offering necessary power support for fixing and operating the tee elbow, and is a key power component for achieving automated operation. A fixed plate 4 is fixedly connected to the drive end of the hydraulic cylinder 3. When the hydraulic cylinder 3 operates, the extension and retraction of its drive end drives the fixed plate 4 to move accordingly, thereby adjusting the position of the fixed plate 4 for better operation of the tee elbow. A rotating plate 5 is rotatably connected to the outside of the fixed plate 4. This rotatable connection allows for angle adjustment of the tee elbow, enabling rust removal operations at different angles, improving the comprehensiveness and accuracy of rust removal. A movable rod 6 is movably connected to the inner wall of the rotating disk 5. The movable rod 6 moves within the inner wall of the rotating disk 5, and its movement drives the movement of other components. A locking block 7 is fixedly connected to the outside of the movable rod 6. The locking block 7 moves with the movable rod 6, further securing the tee elbow and increasing stability. A top block 8 is movably connected to the outside of the movable rod 6. The top block 8 moves accordingly as the movable rod 6 moves. Multiple locking plates 9 are fixedly connected to the inner wall of the rotating disk 5. These plates cooperate with the locking block 7. When the locking block 7 is engaged with the outside of the locking plate 9, it effectively fixes the position of the movable rod 6, thereby improving the stability of the tee elbow. Two push blocks 10 are slidably connected to the inner wall of the rotating disk 5. These push blocks 10 slide along the inner wall of the rotating disk 5, and their sliding is a crucial step in securing the tee elbow. The movement of the push blocks 10 locks the tee elbow in place. Each push block 10 is externally fixed with a gasket 11. The gasket 11, being made of elastic and flexible material, prevents rigid collisions between the push blocks 10 and the tee elbow, while simultaneously fitting tightly against the interior of the tee elbow, increasing friction and making the fixation of the tee elbow more stable. A movable block 12 is externally fixed to the push blocks 10. The movable block 12 moves along with the push blocks 10, interacting with the top block 8. Under the pressure of the top block 8, it moves, thereby driving the push blocks 10 to perform corresponding actions. A spring 13 is fixedly connected to the inner wall of the movable block 12. When the top block 8 presses the movable block 12, the spring 13 will deform and buffer the pressure of the top block 8 through its own elasticity. At the same time, after the top block 8 is removed, the spring 13 can return to its original shape and drive the movable block 12 to reset.
[0026] The adjustment assembly includes a pressure plate 14, which slides on the inner wall of the rotating disk 5. It is a crucial component of the adjustment assembly, using its sliding motion to drive the movement of other parts and achieve angle adjustment. The pressure plate 14 is externally slidably connected to the inner wall of the rotating disk 5, ensuring free movement of the pressure plate 14 within the rotating disk 5. A locking pin 15 is fixedly connected to the inner wall of the pressure plate 14, engaging with a slot 17 on the fixed disk 4. The engagement and disengagement of the locking pin 15 within the slot 17 fix and adjust the angle of the rotating disk 5. A second spring 16 is sleeved on the outside of the locking pin 15. This spring 16 deforms when the locking pin 15 is subjected to external force, storing and releasing energy to control its position and ensure smooth angle adjustment. The fixed disk 4 has multiple slots 17 on its outside. The slots 17 are evenly distributed on the outside of the fixed disk 4. They cooperate with the locking pins 15. When the locking pins 15 are locked in the slots 17, the angle of the rotating disk 5 is fixed. When the locking pins 15 are removed from the slots 17, the rotating disk 5 rotates to adjust the angle.
[0027] A grinding wheel 18 is movably connected to the outside of the housing 2. The grinding wheel 18 is a key component for removing rust from the inside of the tee elbow, rotating and moving to grind the inner wall of the tee elbow and remove rust. A suction pipe 19 is fixedly connected to the inner wall of the housing 2. When the grinding wheel 18 grinds and removes rust from the tee elbow, it generates a large amount of dust. The suction pipe 19 can promptly suck up this dust, maintaining a clean working environment and preventing the dust from harming the health of the operators.
[0028] Spring 16 is externally fixed to the outside of pressure plate 14, with one end of spring 16 fixed to the outside of pressure plate 14. This connection allows spring 16 to deform accordingly as pressure plate 14 moves, thereby controlling the position of locking pin 15. The end of spring 16 away from pressure plate 14 is fixedly connected to the inner wall of rotating disk 5, and the other end of spring 16 is also fixed to the inner wall of rotating disk 5. This ensures that spring 16 can work stably under external force, storing and releasing energy to provide the necessary power support for angle adjustment.
[0029] The locking pin 15 is externally slidably connected to the inner wall of the rotating disk 5. This sliding connection allows the locking pin 15 to move freely within the rotating disk 5, facilitating engagement and disengagement with the slot 17 on the fixed disk 4, thus adjusting the angle. Alternatively, the locking pin 15 is externally movably connected to the inner wall of the slot 17. When the locking pin 15 is engaged with the inner wall of the slot 17, the angle of the rotating disk 5 is fixed. When angle adjustment is needed, the locking pin 15 is pulled away from the inner wall of the slot 17, causing the rotating disk 5 to rotate and thus adjusting the angle.
[0030] The locking block 7 is externally slidably connected to the inner wall of the rotating disk 5. This sliding connection allows the locking block 7 to move along with the movable rod 6, facilitating its engagement with the locking plate 9 to fix the movable rod 6. The locking block 7 is also externally movably connected to the outside of the locking plate 9. When the movable rod 6 rotates, the locking block 7 engages with the outside of the locking plate 9, thus fixing the position of the movable rod 6 and improving the stability of the tee elbow, ensuring that the tee elbow does not wobble during rust removal operations.
[0031] The top block 8 is externally slidably connected to the inner wall of the rotating disk 5. The sliding of the top block 8 on the inner wall of the rotating disk 5 is a key step in achieving the compression of the moving block 12. The movement of the top block 8 drives the movement of the moving block 12 and the push block 10, thus fixing the tee elbow. The outer surface of the top block 8 is in contact with the outer surface of the moving block 12. When the movable rod 6 pushes the top block 8 to move, the top block 8 will contact and compress the outer surface of the moving block 12, causing the moving block 12 to move due to the deformation of the spring 13, allowing the top block 8 to enter. Simultaneously, it drives the push block 10 to move, thus locking the tee elbow.
[0032] The movable block 12 is externally slidably connected to the inner wall of the rotating disk 5. The movable block 12 slides along the inner wall of the rotating disk 5, and this sliding motion is crucial for fixing the tee elbow. The movement of the movable block 12 drives the push block 10 to perform corresponding actions, thereby achieving the fixing and loosening of the tee elbow. One end of the spring 13, away from the movable block 12, is fixedly connected to the inner wall of the rotating disk 5. This connection allows the spring 13 to deform and store energy when the movable block 12 is pressed by the top block 8. When the top block 8 is removed, the spring 13 returns to its original shape, causing the movable block 12 to reset, thus achieving the loosening operation of the tee elbow.
[0033] The working process of this utility model is as follows:
[0034] First, place the tee elbow above the rotating disk 5. Then, push the movable rod 6. The movable rod 6 will cause the top block 8 to press against the moving block 12. The moving block 12 moves due to the deformation of the spring 13 to allow the top block 8 to enter. At the same time, the moving block 12 drives the push block 10 to move. The tee elbow is then locked in place, and the push block 10 is fixed to the tee elbow by the gasket 11. Due to the characteristics of the gasket 11, rigid collisions between components are avoided. At the same time, the gasket 11 fits tightly against the inside of the tee elbow, increasing the friction and making the fixation of the gasket 11 more stable. At this time, by rotating the movable rod 6, the movable rod 6 drives the locking block 7 to lock onto the outside of the locking plate 9 for fixation, improving the stability of the tee elbow fixation.
[0035] When adjusting the angle, by lifting the locking pin 15, the locking pin 15, connected to the pressure plate 14, squeezes the spring 16. The spring 16 is compressed so that the locking pin 15 leaves the slot 17 in the fixed plate 4 and is no longer locked. Then, the rotating plate 5 is rotated. After reaching the appropriate position, the locking pin 15 is released. The spring 16 releases its potential energy, so that the locking pin 15 continues to be locked in the slot 17 for fixation. In this way, the angle adjustment is completed. The cylinder is started to push the grinding wheel 18 to move into the T-shaped elbow. At the same time, the motor is started to drive the grinding wheel 18 to rotate and the suction pipe 19 is turned on. The dust generated by the grinding wheel 18 grinding and removing rust from the T-shaped elbow is sucked in by the suction pipe 19, realizing precise rust removal by adjusting the angle of the T-shaped elbow.
