Description

Technical Field

[0001] This utility model relates to the field of rust removal device technology, and in particular to a rust removal device for steel bar surface. Background Technology

[0002] Rust removal devices for steel bars remove rust from the surface of steel bars through mechanical, chemical, or high-pressure water jet methods. Common types include wire brush wheels / shot blasting machines (high-efficiency batch processing), pickling tanks (rapid chemical rust removal), high-pressure water jets (environmentally friendly and non-destructive), and automated rust removal production lines (integrating straightening, rust removal, and other functions).

[0003] Traditional steel bar surface rust removal devices rely on an electric motor to drive a wire brush to rotate at high speed. The rust layer is scraped off through mechanical friction between the wire and the surface of the steel bar. However, because it is difficult to fix the steel bar, the steel bar may shake or shift during rust removal, resulting in uneven pressure on the surface of the steel bar by the rust removal tool. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rust removal device for steel bars, which aims to improve the problem of uneven pressure on the surface of steel bars caused by the difficulty in fixing the steel bars in traditional rust removal devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

A second support plate is fixedly connected to the outer wall of the second motor.

[0008] Preferably, the internal thread of the clamping plate is connected to the outer wall of the threaded rod, and the outer wall of the threaded rod is rotatably connected to the inside of the second support plate.

[0009] Preferably, a tabletop is fixedly connected to the lower surface of the first support plate, the lower surface of the second support plate is fixedly connected to the upper surface of the tabletop, and a support column is fixedly connected to the lower surface of the tabletop.

[0010] Preferably, a first support rod is provided inside the support column, and a sleeve column is slidably connected to the outer wall of the support column.

[0011] Preferably, a second connecting rod is fixedly connected to the outer wall of the first support rod, and a first gear is fixedly connected to the outer wall of the second connecting rod.

[0012] Preferably, the teeth of the first gear are meshed with a second gear, and a third motor is fixedly connected to the outer wall of the second gear.

[0013] Preferably, the outer wall of the third motor is fixedly connected to a second support rod, the inner side of the second support rod is rotatably connected to the outer wall of the second connecting rod, and the outer wall of the second support rod is fixedly connected to the outer wall of the sleeve column.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the second motor drives the second rotating wheel to rotate, and the belt rotates with the rotation of the second rotating wheel.

The inside of the clamping plate 5 is threadedly connected to the outer wall of the threaded rod 8, and the outer wall of the threaded rod 8 is rotatably connected to the inside of the second support plate 12.

[0028] Specifically, the second support plate 12 is used to support the stable operation of the second motor 13. The second motor 13 drives the second rotating wheel 11 to rotate. Driven by the second motor 13, the second rotating wheel 11 drives the belt 10 to rotate. The belt 10 drives the first rotating wheel 9 to rotate. The first rotating wheel 9 drives the threaded rod 8 to rotate. The threaded rod 8 drives the clamping plate 5 to slide.

The clamping plate 5 can firmly clamp the steel bar to prevent shaking, thereby achieving the effect of clamping the steel bar and ensuring that the steel bar remains stable during the rust removal process without shaking or displacement.

[0029] Reference Figures 3-5 A tabletop 14 is fixedly connected to the lower surface of the first support plate 7, and a support column 15 is fixedly connected to the lower surface of the tabletop 14. A first support rod 16 is provided inside the support column 15, and a sleeve column 17 is slidably connected to the outer wall of the support column 15.

Driven by the third motor 21, the second gear 20 drives the first gear 19 to rotate. The first gear 19 drives the second connecting rod 18 to rotate. The second connecting rod 18 drives the first support rod 16 to rotate. The first support rod 16 drives the support column 15 to slide inside the sleeve column 17. The support column 15 drives the table 14 to rise and fall, thereby achieving the effect of raising and lowering the device. This avoids the need to raise your hand for a long time due to the device being too high, which would cause arm pain and fatigue.

[0031] Working principle: When the steel bar surface rust removal device is needed, the second motor 13 drives the second rotating wheel 11 to rotate, which in turn drives the belt 10 to rotate, causing the first rotating wheel 9 to rotate, which in turn drives the threaded rod 8 to rotate, thereby causing the clamping plate 5 to slide. The inside of the clamping plate 5 slides on the outer wall of the first connecting rod 6, thereby achieving the effect of clamping the steel bar. It can firmly fix the steel bar in the rust removal working position, ensuring that the steel bar remains stable during the rust removal process and does not shake or shift.

[0032] When the height of the device is not suitable for the operator, the third motor 21 drives the second gear 20 to rotate, which in turn drives the first gear 19 to rotate, causing the second connecting rod 18 to rotate, which in turn drives the first support rod 16 to rotate, causing the support column 15 to slide, which in turn drives the table 14 to rise and fall. This achieves the effect of raising and lowering the device. When the height of the rust removal device can be adjusted according to the operator's height, the operator can be in a more comfortable operating posture and will not need to raise their arms for a long time due to the device being too high, which would cause arm pain and fatigue.
