Description

Technical Field

[0001] The utility model relates to the field of spraying equipment, in particular to a steel component pipeline spraying device. Background Art

[0002] During the fabrication of steel structure piping, the inner wall of the pipes needs to be rust-removed, polished, and coated with anti-corrosion agents and paint, depending on the usage scenario and product design requirements.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 6 In the embodiment of the present invention, a steel structure pipeline spraying device includes a central shaft 1, a fixed rod 3, a connecting rod 5 and a nozzle connector 8. The central shaft 1 is a hollow tube. One end of the central shaft 1 is welded with a fixed connector 2. Three fixed rods 3 are provided on the fixed connector 2. One end of the fixed rod 3 is rotatably connected to the fixed connector 2. The other end of the fixed rod 3 is provided with a nylon pulley 4. The middle position of the central shaft 1 is slidably connected to a sliding connector 6. Three connecting rods 5 are rotatably connected to the sliding connector 6. The other end of the connecting rod 5 is rotatably connected to the middle of the fixed rod 3. The top of the central shaft 1 is provided with a nozzle connector 8, and the top of the nozzle connector 8 is provided with a nozzle fixing tube 19. The outside of the nozzle fixing tube 19 is provided with an external thread for threaded connection with the central shaft 1. The locking sleeve 7 is threadedly connected to the central shaft 1. The locking sleeve 7 is rotated to push the sliding connector 6 to move, so that the adjusting rod and the fixing rod 3 can perform an umbrella-like opening and closing movement, so that the utility model can adapt to the inner diameter of steel pipes of different sizes for spraying the inner wall of the pipeline, and has a wide range of uses. A nozzle connector 8 is provided at the top of the central shaft 1, and a nozzle fixing tube 19 is provided at the top of the nozzle connector 8. The outside of the nozzle fixing tube 19 is provided with an external thread for threaded connection with the central shaft 1.

[0022] Among them, a bearing 14 is provided at the center position of the nozzle connector 8, and a connecting pipe 13 is fixedly connected to the inner side of the bearing 14. A driven gear 15 is provided on the top of the connecting pipe 13, and the top of the driven gear 15 is connected to the nozzle fixing cap 9 through a buckle. An L-shaped nozzle 10 is provided inside the nozzle fixing cap 9, and the end of the nozzle 10 without a nozzle is connected to the paint inlet pipe through a clamp. The inside of the nozzle connector 8 is fixedly connected to the motor 17, and a battery 18 is fixedly provided on the opposite side of the motor 17. A driving gear 16 is provided on the top of the motor 17, and the driving gear 16 is engaged with the driven gear 15, so that the nozzle 10 can rotate 360° with the rotation of the motor 17, with a wide spraying range and flexible use.

[0023] Among them, three positioning grooves 21 are evenly distributed on the adjusting external thread 20 on the central axis 1, and three semicircular positioning blocks 22 are provided on the inner side of the sliding connector 6. The positioning blocks 22 are slidably connected to the positioning grooves 21 to prevent the sliding connector 6 from rotating while sliding, making the fixation more firm and increasing stability.

[0024] Among them, the center position of the fixed connecting part 2 is connected to a "human" shaped hook fixing part 11 through a thread, and the center position of the hook fixing part 11 is connected to a dragging hook 12 through a thread.

[0025] The working principle of the present invention is as follows: before use, the end of the nozzle 10 without the nozzle is connected to the paint inlet pipe through a clamp, and the paint pipe passes through the "human" shaped gap of the hook fixing member 11. The present invention is installed on the inner side of one end of the steel structure pipe, so that the nozzle 10 faces the outside of the pipe and is connected to the drag hook 12 using a rope. The locking sleeve 7 on the central axis 1 is rotated, and the locking sleeve 7 pushes the sliding connection member 6 to move, so that the adjusting rod and the fixed rod 3 perform an opening and closing movement similar to an umbrella, thereby driving the adjusting rod to rotate and connect with the fixed rod 3, and the fixed rod 3 is rotated and connected with the fixed connection member 2, so as to change the pulley 4 at the top of the fixed rod 3 and the steel structure pipe. The distance between the inner wall of the pipe and the pulley 4 is adjusted under the pressure of the inner side of the pipe wall to fix the position of the adjusting rod and the fixing rod 3. It can fix steel structure pipes of different sizes and has a wide range of uses. The motor 17 in the nozzle connector 8 is remotely controlled to rotate, and the active gear 16 drives the driven gear 15 to rotate, thereby driving the nozzle 10 fixed on the nozzle fixing cap 9 to rotate. The rotation speed and interval of the motor 17 are controlled by the program to achieve 360° spraying of the pipe wall. The drag hook 12 is pulled at the speed of spraying, so that the three pulleys 4 move at a uniform speed along the inner side of the steel structure pipe wall, which is enough to perform stable spraying operations on longer pipes and improve spraying efficiency and quality.
