The surface covering method is to protect the steel components by spraying, plating, infiltrating, and coating a layer of corrosion-resistant metal or non-metallic material on the surface of the steel structure component. Before the surface of the steel structure component is covered and protected, it is generally necessary to carry out surface pretreatment such as rust removal on the steel structure component. At present, sandblasting rust removal machines are generally used to carry out pretreatment such as rust removal on the steel surface.

One end of the first threaded rod 5 is rotatably mounted on one side inside the cleaning chamber 2, and the first guide rod 6 is fixedly mounted on the bottom of the corresponding two sides inside the cleaning chamber 2. The outer surface of the first threaded rod 5 is symmetrically threaded with a first connecting block 7, and the bottoms of the two first connecting blocks 7 are respectively slidably mounted on the first guide rod 6. The middle parts of the two first connecting blocks 7 are respectively fixedly mounted with a first spray gun 8, and the first spray gun 8 is provided with a first pipe. The first pipe runs through one side of the cleaning chamber 2 and extends outside the cleaning chamber 2, and the first pipe is connected to a sandblasting machine, which is not shown in the figure.

[0027] The use method and advantages of the utility model: When the I-beam sandblasting and rust removal device is used, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using the device, firstly, the electrical equipment in the device is connected to an external power supply and switch. When using the device to perform sandblasting and rust removal on an I-beam, when it is necessary to adjust the position of each spray gun, first turn on the switch of the first motor 4 to make it work. The first motor 4 drives the first threaded rod 5 to rotate. Since the outer wall of the first threaded rod 5 is symmetrically provided with opposite threads, and one end of the first connecting block 7 is slidably mounted on the first guide rod 6, the rotation of the first threaded rod 5 causes the two first connecting blocks 7 to move relative to each other to achieve a change in the distance between the first spray gun 8 and the I-beam. Similarly, turning on the second motor 9 is switched on and off to make it work. Since the outer wall of the second threaded rod 11 is symmetrically provided with opposite threads, the second motor 9 drives the support block 10 to rotate, which makes the two second connecting blocks 13 move relative to each other to change the distance between the second spray gun 14 and the I-beam. That is, the distance between the two first spray guns 8 and the second spray gun 14 and the I-beam can be adjusted respectively according to the functional I-beams of different sizes. By adjusting the distance according to the size of the I-beam, the spray gun can adapt to the surface of the workpiece more accurately, ensure that the sandblasting particles are evenly distributed on the surface of the workpiece, improve the depth and uniformity of sandblasting and rust removal, and thus obtain better surface treatment effect.

[0029] After the rust removal operation is completed, the switch of the fan 19 can be turned on, and the fan 19 works to transport gas into the delivery pipe 17. The air is sprayed out through the first air outlet hood 15 to clean the surface of the first threaded rod 5. At the same time, the air enters the second air outlet hood 16 through the branch pipe 18 and is sprayed out to clean the surface of the second threaded rod 11. This can prevent dust from falling on the first threaded rod 5 and the second threaded rod 11 during sandblasting and affecting the position adjustment of the first connecting block 7 and the second connecting block 13.
