Description

Technical Field

[0001] The invention relates to the field of rust removal equipment, and in particular to a handheld physical and chemical steel bar rust removal device and a use method thereof. Background Art

[0002] During the construction process, due to rain or humid environment, large areas of steel bars are prone to rust, especially those stored in steel bar processing sheds or already tied steel bar cages or steel meshes. For rusted steel bars near the steel bar processing shed, it is faster to use the medium and large rust removal machines in the steel bar processing shed, but for already tied steel bar cages or steel meshes and rusted steel bars exposed to the air in uncast reinforced concrete structures, they can only be manually polished or chemically derusted using rust removers. However, manual polishing and rust removal is not only inefficient but also prone to incomplete rust removal; using chemical rust removers for rust removal is very likely to cause environmental pollution, and because traditional chemical rust removal uses a sprayer to spray out a large amount of chemical rust removers, it is also easy to cause certain harm to the health of construction workers.

[0003] At present, there are two main methods for steel bar rust removal in engineering: physical rust removal and chemical rust removal. Physical rust removal mostly uses medium and large steel bar rust removal machines, which are mostly suitable for places where there are more steel bar raw materials and rust occurs more concentratedly. It is not possible to remove rust from rusted steel bars in multiple locations or steel bars that have been tied. Chemical rust removal mostly uses a sprayer to spray chemical rust removers over a large area. Although this method is more convenient, because the amount of chemical rust remover sprayed by the sprayer is small in contact with the steel bar and the amount of chemical rust remover sprayed is large, it will cause serious environmental pollution and waste. Summary of the invention

[0004] In view of the deficiencies of the existing technologies and methods, the present invention provides a handheld physical and chemical steel bar rust removal device and a method of use, which has the advantages of fixed-point, quantitative, good operability, easy portability and high-efficiency rust removal, and solves the problems of the steel bar rust removal device in physical rust removal having a single structure, a large volume, and can only be used for rust removal at a fixed location and cannot be rusted according to the size of the steel bar, which not only increases the workload of the user but also reduces the practicality of the rust removal device; it also solves the problems of resource waste and environmental pollution caused by chemical rust removal.

[0005] In order to realize the above-mentioned technical features, the purpose of the present invention is realized as follows: a handheld physical and chemical steel bar rust removal device, which includes a functional area frame, a steel bar clamp frame is arranged on one side of the functional area frame, and the steel bar clamp frame includes two symmetrically arranged movable opening clamps, and the movable opening clamps are hinged at two ends of one side of the functional area frame through hinges; a movable wire brush for rust removal of steel bars is slidably installed on the inner side of the head of the movable opening clamp through a sliding groove, and an opening and closing mechanism for controlling the opening and closing of the movable opening clamp is installed between the movable opening clamp and the functional area frame; the back of the movable wire brush is connected to a reciprocating power device for driving it to slide back and forth up and down along the sliding groove; a chemical rust removal device for providing a chemical rust remover is installed between the steel bar clamp frame and the functional area frame.

[0010] When the Y-shaped hinge threaded rod is screwed in, the movable opening pliers are opened; when the Y-shaped hinge threaded rod is screwed out, the movable opening pliers are closed; when the Y-shaped hinge threaded rod is completely screwed out, the two movable opening pliers are completely closed, so that the driving gear is meshed with the driven gear.

[0011] The chemical rust removal device includes a chemical storage bin arranged inside the functional area frame, the chemical storage bin is connected to the back of the movable wire brush through a slurry delivery pipe, and the movable wire brush is processed with a through hole for passing the chemical rust remover and providing the chemical rust remover thereto.

[0012] The chemical storage bin stores a chemical rust remover, wherein the chemical rust remover is DMC-802 chemical rust remover;

[0013] The chemical storage bin adopts a separate storage bin to facilitate the addition of DMC-802 chemical rust remover; the slurry delivery pipe is a latex pipe, the DMC-802 chemical rust remover is weakly acidic, and the latex pipe is resistant to acid and alkali corrosion.

[0014] The chemical storage bin is connected with a high-pressure gas jet machine and is used for spraying the chemical rust remover onto the back of the movable wire brush through a slurry delivery pipe.

[0015] The driving gear adopts a universal shaft structure, and the driving gear can perfectly mesh with the driven gear even if there is a slight displacement.

The movable wire brush performs up and down reciprocating motion. Therefore, when the DMC-802 chemical rust remover is sprayed, it will be in uniform contact with the rusted steel bars to achieve the purpose of improving the efficiency of chemical rust removal.

[0028] 4. The movable opening pliers of the present invention are divided into two parts, the left and right parts, and the opening angle of the opening pliers can be controlled by manually controlling the Y-shaped hinge threaded rod. For rusty steel bars of different sizes, the size of the detachable movable wire brush can be selected to achieve the effect of rust removal of steel bars of different sizes;
