Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, in particular to a rust removal device for building steel structures. Background Art

[0002] In construction operations, steel plates are an important material for building steel structures. They are exposed to the air for a long time and are easily oxidized by oxygen, moisture and other corrosive media, leading to rust. Especially in humid, rainy or high-salt environments, the rust rate will be faster, and rusted steel plates need to be derusted using rust removal equipment.

[0003] At present, the rust removal device for steel plates usually refers to a hand-push rust removal machine. As a walking rust removal equipment, it is specially designed for rust removal and renovation of larger materials and irregular profiles such as steel plates, iron sheets, and large I-shaped channels. The bottom of the hand-push rust removal machine is usually provided with two walking wheels and a grinding roller. The cooperation of the two can make the rust removal machine move, but when the rust removal machine is being transported, the grinding roller is in a stationary state. If you want to push the vehicle body, you need to press the handle to lift the front grinding roller. The rust removal machine is transported by rotating the two walking wheels, but it is more laborious to press the hand to lift the front grinding roller. Therefore, a rust removal device for building steel structures is needed to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0013] When it is necessary to remove rust from the steel plate, the electric push rod can be turned on by the controller to drive the lifting plate to move downward.

[0027] A rust removal device for building steel structure, the working principle is as follows:

[0028] 1): When it is necessary to perform rust removal on the steel plate, the electric push rod 8 can be turned on by the controller 12 to drive the lifting plate 9 to move downward. As the lifting plate 9 descends, the universal wheel 10 will contact the ground.

[0029] 2): At this time, the electric push rod 8 continues to push, and the moving frame 1 will move upward under the action of the reaction force, thereby making the wire brush roller 5 away from the ground.

Then turn on the motor 2 to drive the wire brush roller 5 to rotate through the belt drive to complete the rust removal operation.

[0031] When the rust removal operation of the steel plate is needed, the electric push rod 8 can be turned on by the controller 12 to drive the lifting plate 9 to move downward. As the lifting plate 9 descends, the universal wheel 10 will contact the ground. At this time, the electric push rod 8 continues to push, and the mobile frame 1 will move upward under the action of the reaction force, thereby making the wire brush roller 5 away from the ground, which can prevent the wire brush roller 5 from contacting the ground during transportation. The rolling of the universal wheel 10 and the walking wheel 3 can facilitate the transportation of the device, and it is more labor-saving when pushing. After pushing the device to the use position, the electric push rod 8 is turned on to move upward. At this time, the wire brush roller 5 will contact the steel plate, and then the motor 2 is turned on to drive the wire brush roller 5 to rotate through the belt drive, so as to complete the rust removal operation. When the wire brush roller 5 rotates, it will slide relative to the cleaning brush 17, so that the impurities accumulated on the wire brush roller 5 can be cleaned, thereby improving the rust removal effect.
