During long-term use, the surface of pipes will accumulate pollutants such as rust, oil stains, and old paint. These pollutants not only affect the appearance of the pipes, but may also reduce the corrosion resistance and service life of the pipes.
[0003] Traditional sandblasting relies heavily on manual operation, which is not only inefficient but also inconsistent, resulting in uneven surface treatment. Furthermore, the dust generated during manual sandblasting not only harms workers' health but may also pollute the production environment and increase cleaning costs. To solve these problems, this utility model provides a fully automatic closed sandblasting device for pipelines. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fully automatic closed sandblasting device for pipelines.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An automatic closed-loop sandblasting device for pipelines includes a protective box. A sealed door is hinged to the back of the protective box. A support frame is fixedly connected to the front of the sealed door. A threaded screw is rotatably connected inside the support frame. Movable seats are threaded onto both ends of the threaded screw. A turntable is rotatably connected to one side of the movable seat. A fixing component is fixedly connected to one side of the turntable. A sandblasting machine is fixedly connected to the upper surface of the protective box. A connecting hose is fixedly connected to the output end of the sandblasting machine. A sandblasting head is fixedly connected to the lower end of the connecting hose. A collection component is fixedly connected to the lower surface of the protective box.
[0007] As a further improvement of this utility model, the fixing component includes a mounting bracket fixedly connected to one side of the turntable. An adjusting bolt is rotatably connected inside the mounting bracket. An adjusting block is threaded onto the surface of the adjusting bolt. An adjusting rod is rotatably connected to both the upper and lower ends of the adjusting block. A rotating rod is rotatably connected to the other end of the adjusting rod. The lower end of the rotating rod is fixedly connected to the mounting bracket. A friction block is fixedly connected to the upper end of the rotating rod. A small motor is fixedly connected to one side of the mounting bracket. The power end of the small motor is fixedly connected to the adjusting bolt.
[0008] As a further improvement of this utility model, the collection component includes a support base fixedly connected to the lower surface of the protective box, a collection box fixedly connected inside the support base, a collection drawer movably connected inside the collection box, a collection channel fixedly connected to the upper surface of the collection box, and the upper end of the collection channel fixedly connected to the protective box.
[0009] As a further improvement of this utility model, a handle is fixedly connected to one side of the support frame, and one side of the handle is fixedly connected to a threaded screw.
[0010] As a further improvement of this utility model, a rotary motor is fixedly connected to one side of the movable seat, the power end of the rotary motor is fixedly connected to one side of the turntable, and an electric push rod is fixedly connected to one side of the protective box, the power end of the electric push rod is fixedly connected to the sandblasting head.
[0011] As a further improvement of this utility model, a viewing glass is provided in the middle of the front of the protective box, and control panels are fixedly connected to both sides of the front of the protective box.
[0012] The beneficial effects of this utility model are:
[0013] By setting up a fixed component, during use, turning the handle drives the threaded screw to rotate. Utilizing the opposing thread design inside the two movable seats, the two movable seats move towards each other, quickly clamping the pipe between the turntables. This allows for clamping pipes of different lengths. Simultaneously, the mounting bracket connected to one side of the turntable can enter the pipe as the turntable moves. Activating the small motor drives the adjusting bolt to rotate, and the linkage mechanism of the adjusting block, adjusting rod, and rotating rod ensures that the friction block can tightly fit against the inner wall of the pipe, achieving a firm fixation of pipes of different diameters. This further enhances the stability of the pipe fixation, not only improving the efficiency of pipe fixation and increasing the versatility of the device, but also ensuring the stability of the fixation.
[0014] By setting up a sandblasting machine, when in use, the sandblasting machine uses a connecting hose and a sandblasting head to sandblast the surface of the pipe. Starting the rotary motor drives the turntable and the pipe to rotate, making the sandblasting treatment more uniform and comprehensive. At the same time, the electric push rod drives the sandblasting head to move, which can sandblast different parts of the pipe, ensuring full coverage and uniform treatment of the pipe surface.
[0015] By setting up a protective box, the design of the protective box and the airtight door creates a closed sandblasting environment during use, effectively preventing sand and dust from flying and spreading, protecting the health of operators and the environment. At the same time, the collection box and collection drawer can collect the sand and dust generated during the sandblasting process, which is convenient for subsequent processing and recycling, reducing environmental pollution.
[0016] In summary, this utility model has many beneficial effects, including efficient fixing and adjustment, comprehensive sandblasting treatment, sealed environment and environmentally friendly design, convenient and visual operation, and stable and durable structure. Attached Figure Description

[0023] Reference Figures 1-4 An automatic closed-loop sandblasting device for pipelines includes a protective box 1. A closed door 2 is hinged to the back of the protective box 1. A support frame 3 is fixedly connected to the front of the closed door 2. A threaded screw 4 is rotatably connected inside the support frame 3. Movable seats 5 are threaded onto both ends of the surface of the threaded screw 4. A turntable 6 is rotatably connected to one side of the movable seat 5. A fixing component is fixedly connected to one side of the turntable 6. A sandblasting machine 7 is fixedly connected to the upper surface of the protective box 1. A connecting hose 8 is fixedly connected to the output end of the sandblasting machine 7. A sandblasting head 9 is fixedly connected to the lower end of the connecting hose 8. A collection component is fixedly connected to the lower surface of the protective box 1.
[0024] In this utility model, the fixing component includes a mounting bracket 16 fixedly connected to one side of the turntable 6. An adjusting bolt 10 is rotatably connected inside the mounting bracket 16. An adjusting block 11 is threadedly fitted onto the surface of the adjusting bolt 10. The threaded engagement between the adjusting block 11 and the adjusting bolt 10 allows the rotation of the adjusting bolt 10 to be converted into the linear motion of the adjusting block 11. An adjusting rod 12 is rotatably connected to both the upper and lower ends of the adjusting block 11. A rotating rod 13 is rotatably connected to the other end of the adjusting rod 12. The two ends of the adjusting rod 12 are rotatably connected to the adjusting block 11 and the rotating rod 13, respectively, forming a lever structure to amplify the motion effect of the adjusting block 11. The lower end of the rotating rod 13 is fixedly connected to the mounting bracket 16, and the upper end of the rotating rod 13 is fixedly connected to a friction block 14. The friction block 14 serves as the final action component of the fixing component, achieving tight fixing of the pipe through its positional changes. A small motor 15 is fixedly connected to one side of the mounting bracket 16. The power end of the small motor 15 is fixedly connected to the adjusting bolt 10, providing power for the rotation of the adjusting bolt 10 and realizing the automated adjustment of the fixing component.
[0025] The collection assembly includes a support base 17 fixedly connected to the lower surface of the protective box 1. A collection box 18 is fixedly connected inside the support base 17. A collection drawer 19 is movably connected inside the collection box 18. The design of the collection drawer 19 makes the cleaning of sand and dust more convenient and improves work efficiency. A collection channel 20 is fixedly connected to the upper surface of the collection box 18. The upper end of the collection channel 20 is fixedly connected to the protective box 1. The collection channel 20 serves as a guide channel for sand and dust, ensuring that sand and dust can smoothly enter the collection box 18.
[0026] A handle 21 is fixedly connected to one side of the support frame 3. The design of the handle 21 facilitates manual operation of the threaded screw 4 by the operator, increasing the flexibility of the device. One side of the handle 21 is fixedly connected to the threaded screw 4. A rotary motor 22 is fixedly connected to one side of the movable seat 5. The rotary motor 22 provides power for the rotation of the turntable 6, realizing the automatic rotation of the pipeline. The power end of the rotary motor 22 is fixedly connected to one side of the turntable 6. An electric push rod 23 is fixedly connected to one side of the protective box 1. The power end of the electric push rod 23 is fixedly connected to the sandblasting head 9. The electric push rod 23 provides power for the movement of the sandblasting head 9, realizing the automatic adjustment of the sandblasting position. A viewing glass 24 is set in the middle of the front of the protective box 1. The design of the viewing glass 24 facilitates the operator to observe the sandblasting process in real time, improving the convenience and safety of operation. Control panels 25 are fixedly connected to both sides of the front of the protective box 1. The setting of the control panels 25 facilitates the operation of the device by the staff.
[0027] In use, the pipe is first placed between the two turntables 6. The handle 21 is turned to rotate the threaded screw 4. Since the threads inside the two movable seats 5 are in opposite directions, the rotation of the threaded screw 4 drives the two movable seats 5 to move towards each other. As the movable seats 5 move, the two turntables 6 also move towards each other until the pipe is clamped in the middle. At the same time, the mounting bracket 16 connected to one side of the turntable 6 will enter the pipe. Then, the small motor 15 is started to drive the adjusting bolt 10 to start rotating. The rotation of the adjusting bolt 10 will cause the adjusting block 11, which is threaded onto its surface, to move along the screw axis. During the movement of the adjusting block 11, the adjusting rods 12, which are rotatably connected to its upper and lower ends, will also change position, thereby changing the angle of the rotating rod 13. When the angle of the rotating rod 13 changes, the friction block 14 fixed at one end will move towards the inner wall of the pipe, so that the two friction blocks 14 are tightly attached to the inner wall of the pipe, thereby firmly fixing the pipe.
[0028] Then, the sandblasting machine 7 is turned on, and the abrasive produced is transported to the sandblasting head 9 through the connecting hose 8 to carry out sandblasting processing on the pipe surface. At the same time, the rotary motor 22 is started to drive the turntable 6 to rotate slowly, thereby driving the pipe to rotate synchronously, ensuring that all parts of the pipe surface can be uniformly sandblasted. The electric push rod 23 is started, and its extension and retraction movement guides the sandblasting head 9 to move along a predetermined trajectory to carry out comprehensive sandblasting operations on different parts of the pipe. During this process, the sand and dust generated by the sandblasting operation flow into the collection drawer 19 in the collection box 18 through the collection channel 20.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
