Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar rust removal, in particular to a steel bar rust removal device for construction. Background Art

[0002] Rust is formed when metal reacts with oxygen and water in the air. When oxygen in the air dissolves in water, oxygen reacts with iron in a water environment to form a kind of rust called iron oxide. When iron is completely rusted, its volume expands 8 times. If it is not removed in time, it will accelerate the decay of metals such as steel bars. It is very normal for steel bars to rust. Only when the steel bars are rusted can they be used normally. The most common method is manual rust removal. When removing rust manually, you usually need to hold a tool such as a high-pressure spray gun to spray the rust remover onto the surface of the steel bars. It is troublesome to turn the steel bars manually, but the rust remover is difficult to evenly fall on the steel bars, thus affecting the efficiency of rust removal. Utility Model Content

[0021] An electric telescopic rod 9 is fixedly installed on one side of the limiting tube 5, and a fixing plate 10 is fixedly connected to the output end of the electric telescopic rod 9 and located inside the limiting tube 5. By extending the electric telescopic rod 9, it is convenient to push the fixing plate 10 to fix steel bars of different sizes in the limiting tube 5.

[0022] A limiting groove 11 is provided inside the support plate 12 and on one side of the multiple limiting tubes 5, and a first gear 6 is sleeved on the outer side of the multiple limiting tubes 5. A second gear 7 is rotatably connected to one side of the support plate 12 and located between the multiple first gears 6. An inner ring gear 8 is fixedly installed on the inner wall of the support frame 4, and the multiple first gears 6 are respectively meshed with the second gear 7 and the inner ring gear 8. By utilizing the meshing between the multiple first gears 6, the second gear 7 and the inner ring gear 8, when the second gear 7 rotates, it can trigger the rotation and revolution of the multiple first gears 6, so that the steel bars in the multiple limiting tubes 5 can circulate and move, which is convenient for the rust remover to be evenly sprayed on the surface of the multiple steel bars, which is beneficial to improving the efficiency of steel bar rust removal.

[0023] The distances between multiple first gears 6 are equidistant, so that the moving speeds between multiple steel bars remain consistent. A first connecting shaft 14 is fixedly connected to one side of one second gear 7, and a second connecting shaft 15 is slidably connected inside the first connecting shaft 14. One end of the second connecting shaft 15 is fixedly connected to another second gear 7.

Second pulleys 18 are rotatably connected inside the groove 16 and at both sides corresponding to the first pulley 17. A traction rope 19 is fixedly connected to the outer side of the shaft of the first pulley 17. Both ends of the traction rope 19 are respectively passed around the two second pulleys 18 and fixedly connected to the slider 3. The retraction and release of the traction rope 19 is controlled by the rotation of the second pulley 18, so that the two ends of the traction rope 19 drive the displacement of the slider 3 and the support frame 4, so that the surface of the steel bar blocked by the support frame 4 is exposed. To facilitate all-round rust removal of steel bars, a telescopic spring 20 is fixedly connected between the two sliders 3 to provide a force for the resetting of the two sliders 3.

Since the outer sides of the plurality of limiting tubes 5 are sleeved with the first gear 6, and the plurality of first gears 6 are respectively meshed with the second gear 7 and the inner gear ring 8 inside the support frame 4, the gear teeth 8 are rotated, and the plurality of The first gear 6 and the limiting tube 5 rotate and orbit around each other. Similarly, the steel bars inside the limiting tubes 5 rotate and orbit around each other along with the first gear 6, so that the rust remover is evenly sprayed on the surface of the multiple steel bars. After a period of time, the first pulley 17 inside the base plate 1 can be rotated, and the rotation of the first pulley 17 can be used to control the retraction and release of the traction rope 19, so that the two ends of the traction rope 19 respectively trigger the displacement of the sliders 3 at the bottom of the two support frames 4, exposing the parts of the steel bars blocked by the support frames 4, thereby completing all the rust removal work.
