[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention proposes a surface rust-proofing method for cold-drawn steel columns. A cylinder is used to raise and lower a connecting frame, simultaneously raising and lowering a liquid storage tank. This applies pressure to the cold-drawn steel column placed on a moving platform, while rust-proofing liquid flows out through a drain hole. A drive motor then rotates a lead screw, moving the platform so that a brush can apply the rust-proofing liquid to the cold-drawn steel column. When the cylinder's output end retracts, it lowers the second connecting plate, causing one end of the third connecting plate to rise, thus raising the connecting frame. When the cylinder's output end extends, it raises the second connecting plate, causing one end of the third connecting plate to fall, thus lowering the connecting frame. This achieves the pressure application. By controlling the pressure, the application effect of the rust-proofing liquid can be adjusted. The rust-proofing liquid is introduced into the storage chamber through a groove and an inlet, facilitating its outflow through the drain hole. The brush strips and outlets are staggered on the lower surface of the storage tank, which facilitates even application of the rust-preventive liquid. A drive motor rotates the lead screw, causing the slider and sliding frame to move on the base, simultaneously moving the cold-drawn steel column placed on the moving platform, facilitating the brushing operation. During brushing, excess rust-preventive liquid flows through the drain hole into the inclined groove and then into the collection chamber for subsequent unified treatment, preventing waste. The included insert rods, springs, fasteners, and handles facilitate the installation and disassembly of the storage tank, enabling timely cleaning and maintenance. This avoids the problems of manual rust-preventive coating, resulting in substandard coating quality, uneven coating thickness, large areas of brush marks, significant waste of rust-preventive liquid, and a chaotic work environment, severely impacting the surface quality and efficiency of the cold-drawn steel and wasting time and effort.

Furthermore, all embodiments can be used in combination with each other.

[0032] Example 1

[0033] Please see Figures 1 to 9This invention provides a technical solution: a cold-drawn steel column with surface anti-rust treatment, comprising: a first support column 1, a second support column 9 arranged beside the first support column 1, a crossbeam 17 arranged between the first support column 1 and the second support column 9, a first connecting plate 12 arranged above the crossbeam 17, a fourth connecting plate 16 arranged on the first connecting plate 12, push cylinders 11 arranged on both sides of the first connecting plate 12, a second connecting plate 13 and a third connecting plate 14 arranged on both sides of the fourth connecting plate 16, a connecting frame 15 arranged at one end of the third connecting plate 14, and the interior of the connecting frame 15... A liquid storage tank 26 is provided, and the lower surface of the liquid storage tank 26 is provided with a liquid outlet 36 and a coating strip 27; irregularly shaped base blocks 19 are fixed on both sides of the first connecting plate 12, and a push cylinder 11 is provided on the surface of the irregularly shaped base block 19. The push cylinder 11 is fixedly connected to the irregularly shaped base block 19 and the first connecting plate 12 by bolts. The output end of the push cylinder 11 is fixedly connected to one end of the second connecting plate 13, and the other end of the second connecting plate 13 is fixedly connected to the second support rod 22. The third connecting plate 14 is rotatably connected to the second support rod 22 and the first support rod 21. The fourth connecting plate 16 is fixedly connected to the first support rod 21.

[0034] In use, when the output end of the cylinder 11 retracts, it causes the second connecting plate 13 to descend, which in turn causes one end of the third connecting plate 14 to rise, thereby causing the connecting frame 15 to rise. When the output end of the cylinder 11 extends, it causes the second connecting plate 13 to rise, which in turn causes one end of the third connecting plate 14 to descend, thereby causing the connecting frame 15 to descend. This achieves the pressure operation. By controlling the pressure, the coating effect of the rust inhibitor can be adjusted. The rust inhibitor is injected into the storage chamber 44 through the groove 28 and the inlet 24, and the rust inhibitor can flow out through the drain hole 18. The brush strips 27 and the outlet 36 are arranged alternately on the lower surface of the storage tank 26, which is conducive to the even coating of the rust inhibitor.

[0035] Example 2

[0036] Based on Embodiment 1, to collect excess rust inhibitor, a collection frame 5 is provided at the front of the base 4, a drive motor 10 is provided on the side of the base 4, a sliding groove 39 is provided inside the base 4, a lead screw 40 and a slider 41 are provided in the sliding groove 39, a sliding outer frame 3 is provided above the slider 41, a moving platform 43 is provided inside the sliding outer frame 3, the moving platform 43 is located directly below the connecting frame 15, an inclined groove 38 is provided inside the base 4, and a collection cavity 3 is provided inside the collection frame 5. 7. The inclined groove 38 and the collection chamber 37 correspond to each other. The upper surface of the base 4 is provided with a sliding groove 39. The slider 41 is adapted to the sliding groove 39. The surface of the slider 41 is provided with a third through hole 42. The lead screw 40 is adapted to the third through hole 42. A sliding outer frame 3 is fixed above the slider 41. A moving platform 43 is fixed inside the sliding outer frame 3. The moving platform 43 is in the shape of a square plate. The surface of the sliding platform is provided with a leakage hole 18. There are several leakage holes 18. The several leakage holes 18 are evenly distributed on the surface of the sliding platform.

[0037] In use, the drive motor 10 drives the lead screw 40 to rotate, thereby causing the slider 41 and the sliding outer frame 3 to move on the base 4, which in turn moves the cold-drawn steel column placed on the moving table 43, facilitating the coating operation. During coating, excess rust inhibitor will flow through the drain hole 18 into the inclined groove 38, and then into the collection chamber 37, which is convenient for subsequent unified treatment and avoids waste of rust inhibitor.

[0038] Example 3

[0039] Based on Embodiment 2, the liquid storage tank 26 is conveniently installed and disassembled. A rod 33 is inserted into the second through hole 34. A spring 32 is sleeved on the surface of the rod 33. A fastener 29 is fixed to the end face of the rod 33. One end of the spring 32 is fixedly connected to the fastener 29, and the other end of the spring 32 is fixedly connected to the connecting frame 15. A handle 30 is fixed to the surface of the fastener 29. A rubber pad 31 is fixed to the inner surface of the handle 30. First through holes 25 are opened on both sides of the liquid storage tank 26, and the rod 33 can be inserted into the first through hole 25.

[0040] In use, when it is necessary to disassemble the liquid storage tank 26, manually turn the handle 30 to disengage the insertion rod 33 from the first through hole 25 and the second through hole 34, thus disassembling the liquid storage tank 26. When it is necessary to install the liquid storage tank, first manually turn the handle 30 to disengage the insertion rod 33 from the second through hole 34, and then insert the liquid storage tank 26 into the cavity 35 accordingly. When the liquid storage tank is fully inserted into the cavity 35, the first through hole 25 and the second through hole 34 correspond. At this time, release the handle 30, and the insertion rod 33 will automatically insert into the first through hole 25 and the second through hole 34 under the rebound action of the spring 32, thereby limiting the liquid storage tank 26 and realizing the installation of the liquid storage tank 26. The cavity 35 is trapezoidal and corresponds to the connecting frame 15 to prevent flipping. The inner surface of the rubber pad 31 is provided with anti-slip texture to prevent slippage when turning the handle 30.

[0041] Working principle: In actual use, the first support column 1 and the second support column 9 are fixed to the ground by bolts through the limiting holes. The cold-drawn steel column is then placed on the moving platform 43. The connecting frame 15 is raised and lowered by pushing the cylinder 11, which in turn raises and lowers the liquid storage tank 26. This applies pressure to the cold-drawn steel column placed on the moving platform 43, while the rust-preventive liquid flows out through the leakage hole 18. The drive motor 10 drives the lead screw 40 to rotate, thus moving the moving platform 43. The coating strip 27 then applies the rust-preventive liquid to the cold-drawn steel column. This avoids the problems of manual rust-preventive coating, poor coating quality, uneven coating thickness, large areas of brush marks, waste of rust-preventive liquid, and a chaotic working environment, which seriously affect the surface quality and coating efficiency of the cold-drawn steel column and are time-consuming and labor-intensive.
