Description

Technical Field

[0001] This utility model relates to the field of steel bar rust removal technology, and more specifically to a pre-embedded external steel bar rust removal device. Background Technology

[0002] In engineering construction, a large number of steel bars are usually used as building components. In order to facilitate the rapid construction of the entire building, some steel bars are usually embedded and exposed. These steel bars are exposed to the air for a long time and often rust, which usually requires rust removal treatment.

[0003] Currently, rust removal operations typically involve manual operation using a bucket carried on the back. Workers pump out the rust-removing solution from the bucket and spray it onto the rusted steel bars to remove the rust. However, when removing rust from vertical steel bars, workers must first spray the surface from top to bottom, and then change direction to spray the unsprayed areas from top to bottom again. While this method ensures that the rust-removing solution covers all parts of the steel bars, it is inefficient and time-consuming. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a rust removal device for pre-embedded exposed steel bars to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution:

[0024] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0025] Figures 1-8 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 ~Appendix Figure 8 The present invention will be further described below.

[0026] A rust removal device for pre-embedded exposed rebar includes: a working bucket 1, with two shoulder straps fixedly connected to one side of the working bucket 1; a liquid inlet pipe 5 fixedly connected to the water inlet of the working bucket 1; a protective cap 6 threadedly connected to the outer wall of the liquid inlet pipe 5; an operating column 4 on one side of the working bucket 1; an operating chamber 9 inside the operating column 4; two rust removal components inside the operating chamber 9; a third sliding hole 25 on the outer wall of the operating column 4, communicating with the operating chamber 9; a pressing component inside the third sliding hole 25; and a driving component connected to the pressing component. The pressing component moves up and down along the third sliding hole 25, which drives the two rust removal components to move closer or further apart via the driving component. Each rust removal component includes a waterproof pump 7, which is fixedly connected to the working bucket 1. The inner bottom wall of the working bucket 1 is fixedly connected to the outlet of the diversion pipe 2. The drain pipe of the waterproof pump 7 is fixedly connected to the diversion pipe 2. Two round holes are opened on the outer wall of the diversion pipe 2. The hose 3 is fixedly connected to the inside of the round holes. Two moving columns 18 are provided inside the operating chamber 9. The hose 3 is fixedly connected to the inside of the moving columns 18. A second sliding hole 19 is opened at one end of the operating column 4. The second sliding hole 19 is connected to the operating chamber 9. One end of the moving column 18 passes through the second sliding hole 19 and extends to the outer wall of the operating column 4. A water spray ring 20 is fixedly connected to one end of the moving column 18. Several round holes are opened on the inner wall of the water spray ring 20. The nozzle 21 is fixedly connected to the inside of the round holes. A fixing hole 24 is opened on the outer wall of the water spray ring 20. The hose 3 is fixedly connected to the fixing hole 24.

[0027] Specifically, the rust removal component also includes: a first sliding hole 8, which is located at one end of the operating column 4 and is movably connected to the hose 3.

[0028] In this embodiment, the first sliding hole 8 facilitates the movement of the hose 3 inside the first sliding hole 8.

[0029] Specifically, the pressing component includes: a movable block 17, which is slidably connected inside the third sliding hole 25. Sliding grooves 13 are respectively opened on both sides of the interior of the third sliding hole 25. A sliding block 14 is slidably connected inside the sliding groove 13. The sliding block 14 is fixedly connected to the movable block 17. The pressing component also includes: a fixed rod 15, which is fixedly connected inside the sliding groove 13. A round hole is opened on the top surface of the sliding block 14, which is slidably connected to the fixed rod 15. A first return spring 16 is fixedly connected to the bottom surface of the sliding block 14. The first return spring 16 is located outside the fixed rod 15, and one end of the first return spring 16 is fixedly connected to the inner bottom wall of the sliding groove 13.

[0030] In this embodiment, when the movable block 17 is subjected to force and moves downward, it will slide on the outer wall of the fixed rod 15 through the sliding block 14 and squeeze the first reset spring 16. When the movable block 17 loses external force, the potential energy of the first reset spring 16 is released, which can drive the sliding block 14 and the movable block 17 to reset.

[0031] Specifically, the driving component includes: two connecting rods 12, which are rotatably connected to both sides of the moving block 17; a connecting seat 11 is fixedly connected to one side of the moving column 18; the connecting rods 12 are rotatably connected to the connecting seat 11; a first guide rod 10 is fixedly connected inside the operating cavity 9; a round hole is opened on one side of the moving column 18; the moving column 18 is slidably connected to the first guide rod 10 through the round hole; and the connecting rods 12 are slidably connected to the first guide rod 10.

[0032] In this embodiment, the connecting rod 12, when rotated, will squeeze the connecting seat 11, causing the connecting seat 11 to drive the moving column 18 to move on the first guide rod 10, thereby causing the two moving columns 18 to drive the spray rings 20 away from each other, achieving the effect of adjusting the distance between the two spray rings 20.

[0033] Specifically, the driving component also includes: several second guide rods 23, which are all fixedly connected inside the operating cavity 9; several round holes are provided on one side of the moving column 18; the moving column 18 is slidably connected to the second guide rods 23 through the round holes; a second return spring 22 is fixedly connected to one side of the moving column 18; the second return spring 22 is located on the outer wall of the second guide rods 23; and one end of the second return spring 22 is fixedly connected to the inner wall of the operating cavity 9.

[0034] In this embodiment, when the two movable columns 18 move away from each other, the movable column 18 will slide on the second guide rod 23 and squeeze the second return spring 22 to contract. When the movable column 18 loses external force, the potential energy of the second return spring 22 is released, which can drive the movable column 18 to reset, so that the two movable columns 18 move closer to each other and fit together.

[0035] The working principle and usage process of this utility model are as follows: During use, the worker can carry the work bucket 1 on their back using the shoulder strap, then hold the operating column 4 horizontally and place their thumb on the moving block 17. When rust removal of the vertical reinforcing bars is required, the worker presses down on the moving block 17. The moving block 17 moves downward, causing the sliding block 14 to slide against the outer wall of the fixed rod 15, simultaneously compressing the first return spring 16. At the same time, the downward movement of the moving block 17 causes the connecting rod 12 to rotate, causing the other end of the connecting rod 12 to press against the moving column 18 through the connecting seat 11. The two movable columns 18 slide on the first guide rod 10 and move away from each other. Simultaneously, as the two movable columns 18 move, they also move on the second guide rod 23 and compress the second return spring 22. This causes the movable columns 18 to move the two water spray rings 20 away from each other. Then, the worker can slip the two water spray rings 20 onto the top of the vertical rebar. After the worker releases the movable block 17, the potential energy of the second return spring 22 and the first return spring 16 is released, causing the two movable columns 18 to come together and reset the movable block 17. This shortens the distance between the two spray rings 20 and the reinforcing bars after they come together, ensuring that the rust remover can cover the surface of the vertical reinforcing bars. At this time, the waterproof pump 7 draws the rust remover from the working bucket 1 and pumps it into the spray rings 20 through the diversion pipe 2 and the hose 3. As the worker holds the operating column 4 and moves the spray rings 20 downwards on the vertical reinforcing bars, the nozzle 21 sprays the rust remover onto the surface of the vertical reinforcing bars to achieve the rust removal effect. At the same time, when it is necessary to perform rust removal on the horizontal reinforcing bars, the worker can adjust the operating column 4 to a vertical position. Then, following the above steps, first... The two water spray rings 20 are moved apart, and then inserted from both sides of the outer wall of the transverse steel bar. The two water spray rings 20 are then brought together, so that the distance between the two water spray rings 20 and the transverse steel bar is shortened. Finally, they are moved laterally on the transverse steel bar to remove rust from the transverse steel bar as a whole. Compared with the prior art, this application makes it easier to fit the two water spray rings 20 onto the outer wall of the steel bar by adjusting the distance between them, so as to remove rust from the vertical steel bar and the transverse steel bar respectively. Moreover, the rust removal does not require repeated operation, making the operation convenient and the rust removal efficiency high.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
