Description

Technical Field

[0001] The utility model belongs to the field of steel bar anti-rust devices, in particular to a pre-buried exposed steel bar anti-rust device. Background Art

[0002] Pre-embedded steel bars are placed in the structure in advance according to the design drawings, and then the concrete is poured. Because they are inside the concrete, the appearance quality of the original object itself and whether it is placed accurately cannot be seen after the construction is completed. Before proceeding to the next process, it must be ensured that the pre-embedded exposed steel bars are not rusted and corroded before subsequent construction can be carried out. In order to prevent the pre-embedded exposed steel bars from rusting, two methods are usually used: sealed wrapping for rust prevention and brushing for rust inhibitors. Although the wrapping for rust prevention method can better achieve rust prevention effects, it is more expensive and the installation and disassembly are more troublesome. The method of brushing for rust inhibitors usually adopts the method of manual brushing, which not only makes the construction personnel work under great pressure but also fails to complete the brushing more evenly, thereby causing waste of rust inhibitors and affecting the rust prevention effect.

[0017] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0018] Example 1

[0019] The present embodiment describes a pre-buried exposed steel bar anti-rust device, such as Figure 1As shown, it comprises a first fixed tube 2, wherein the upper and lower ends of the first fixed tube 2 are provided with second fixed tubes 1 which can rotate freely left and right with the first fixed tube 2, so as to facilitate the installation of steel bars inside the first fixed tube 2;

[0020] A third fixing tube 3 is horizontally fixed to the outer side wall of the first fixing tube 2, so as to facilitate the operator to hold it;

[0021] The third fixed tube 3 is provided with a driving assembly for driving the second fixed tube 1 to rotate, and the second fixed tube 1 is provided with a plurality of brushes 7 for painting the surface of the steel bar, so as to facilitate rapid and uniform painting of the surface of the steel bar;

[0022] The second fixed pipe 1 located at the bottom is provided with a liquid storage bottle 6 for injecting rust inhibitor into the interior thereof, so as to facilitate brushing the rust inhibitor on the surface of the steel bar with a brush 7 .

[0023] The third fixed pipe 3 is in a rectangular structure as a whole, and the corners are rounded, so that the operator can exert force better, so that the operator can maintain stability and avoid slipping when the second fixed pipe 1 rotates to apply the anti-rust agent to the steel bars;

[0024] The outer surface of the third fixing tube 3 can also be covered with an anti-slip sleeve to increase friction, which is convenient for operators to hold the tube better and improves comfort.

[0025] like Figure 1 and Figure 2 As shown, a sealing sleeve 13 is provided between the two second fixed tubes 1 to prevent the rust preventive agent from entering the first fixed tube 2, and the sealing sleeve 13 is elastic, so as to block the splashing rust preventive liquid during the painting process, which is convenient for avoiding waste and preventing the rust preventive liquid from entering the first fixed tube 2 to damage the second gear 10, the first gear 11 and the bearing, thereby improving their service life;

[0026] The sealing sleeve 13 is installed between the inner side walls of the two second fixed tubes 1. When the sealing sleeve 13 is installed between the outer side walls of the two second fixed tubes 1, the opposite end faces of the second fixed tubes 1 are provided with inclined surfaces inclined toward the outer ends thereof. For example, the bottom face of the second fixed tube 1 located at the top is provided with a funnel-shaped inclined surface which is upward and contracted inward, and the top face of the second fixed tube 1 located at the bottom is similarly provided with a funnel-shaped inclined surface which is symmetrically distributed therewith, so that the rust inhibitor splashed on the sealing sleeve 13 can flow downward quickly, thereby reducing waste and lowering the difficulty of cleaning to a certain extent.

[0027] Example 2

[0028] This embodiment further illustrates the technology. Figure 1 and Figure 2As shown, the driving assembly includes two first gears 11, the two first gears 11 are respectively mounted on the second fixed tube 1, and a second gear 10 meshing with the two first gears 11 is vertically arranged between the two first gears 11, a first through hole connected to the third fixed tube 3 is opened on the first fixed tube 2, a connecting rod 12 freely rotating therewith is passed through the first through hole, and one end of the connecting rod 12 is fixed to the second gear 10, and the other end is connected to the motor 5, so that the two second fixed tubes 1 are driven to rotate by the motor 5, thereby driving the brush 7 inside thereof to paint the steel bars;

[0029] The motor 5 is a servo motor, so that the speed can be adjusted accurately.

[0030] The rotation between the second fixing tube 1 and the first fixing tube 2 and the rotation between the connecting rod 12 and the first through hole are both completed through the bearing. Figure 1 and Figure 2 As shown;

[0031] The outer end of the third fixed tube 3 is provided with a sealing plug 4 for sealing it, and the sealing plug 4 is in interference fit or threaded fit with it, which is convenient for maintenance of the motor 5 and installation of the battery when in use.

[0032] A second through hole communicating left and right is provided on the side wall of the second fixed tube 1 located at the bottom, the liquid outlet end of the liquid storage bottle 6 is threadedly matched with the second through hole, and a second brush is provided at the liquid outlet end of the liquid storage bottle 6 located in the second fixed tube 1, and the second brush fits against the surface of the steel bar, so that the rust inhibitor can be injected into the second fixed tube 1 by squeezing the liquid storage bottle 6 and applied to the surface of the steel bar by the second brush, and further evenly applied by the brush 7 when the second fixed tube 1 is moved up and down.

[0033] like Figure 1 and Figure 3 As shown, a baffle 9 is horizontally fixed to the outer end of the second fixed tube 1, and a third through hole is provided on the baffle 9 for the steel bar to pass through. A sealing block 8 is provided in the third through hole to seal it, and a "cross" opening for the steel bar to pass through is provided at the center of the sealing block 8. When the steel bar is located in the third through hole, the sealing block 8 fits with the surface of the steel bar to facilitate blocking the rust inhibitor. At the same time, the rust inhibitor is applied to the surface of the steel bar again during the up and down movement of the second fixed tube 1, which reduces the waste of the rust inhibitor to a certain extent.

[0034] A gap is left between the baffle plate 9 located above and the top surface of the second fixed tube 1, and a groove is formed between the top surface of the second fixed tube 1 and the baffle plate 9, so that the rust inhibitor scraped off by the sealing block 8 can be collected when the second fixed tube 1 moves up and down, thereby further reducing the waste of the rust inhibitor and reducing the environmental pollution caused by the rust inhibitor, making cleaning easier.

[0035] The working principle is to first insert the steel bar into the second fixed tube 1, then install the liquid storage bottle 6 filled with rust inhibitor in the second through hole, and then start the motor 5 to drive the second fixed tube 1 to rotate. At the same time, the operator holds the third fixed tube 3 to drive the second fixed tube 1 to move up and down.
