[0002] Construction refers to the production activities in the implementation stage of engineering construction, which is the construction process of various buildings. With the development of the construction industry, more and more steel pipes are used in various buildings, and the problem of rusting of steel pipes will also occur. In the process of construction, it is often necessary to use steel pipe rust removal equipment to remove rust on the surface of steel pipes.

[0003] A Chinese patent with announcement number CN216608508U discloses an automated rust removal device for steel pipes used in construction, comprising a rust removal box, a rotating fastening platform, a fastening assembly, an external rust removal assembly, a telescopic hydraulic rod and an internal rust removal assembly, wherein the rust removal box is arranged in a hollow cavity with an opening on one side, the rotating fastening platform is rotatably arranged in one end of the rust removal box, the fastening assembly is arranged in the rotating fastening platform, the external rust removal assembly is symmetrically arranged in both ends of the rust removal box, and the telescopic hydraulic rod is arranged at one end of the rust removal box away from the rotating fastening platform; the automated rust removal device for steel pipes used in construction proposed in this scheme facilitates comprehensive rust removal of steel pipes, and is also convenient for rust removal of steel pipes of different diameters, thereby increasing the scope of application of the device and improving work efficiency.

[0004] Since a large amount of dust and particulate matter will be generated during the grinding and rust removal process, the existing steel pipe rust removal device does not have a dust removal mechanism. A large amount of dust and particulate matter will be directly released into the environment without being filtered and collected by the dust collection mechanism, causing air pollution and having a negative impact on the surrounding environment and human health. Therefore, a rust removal device for construction is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised by the above-mentioned background technology, the utility model proposes a rust removal device for building construction.

[0006] The slidable lifting device is a kind of in-built support, and its top is the support frame, and its top end is provided with a cylinder pressure, and its bottom end is provided with a cylinder pressure, and its top end is provided with a cylinder pressure, and its bottom end is provided with a cylinder pressure. The bottom end of the limit rod is fixedly connected to the mounting seat, the top end of the threaded rod is fixedly connected to a rotating disk, the dust box is equipped with a negative pressure pump, the input hole of the negative pressure pump is connected to an exhaust pipe, and the exhaust pipe is arranged in the dust box, and the output hole of the negative pressure pump is connected to an exhaust pipe. During the grinding and rust removal process, the negative pressure pump is started to extract the gas in the dust box through the exhaust pipe and discharge it through the exhaust pipe, so that the interior of the dust box is in a negative pressure state, so that a large amount of dust and particulate matter generated during the grinding and rust removal process can be sucked into the dust box through the dust suction pipe, so that the dust and particulate matter generated during the grinding and rust removal process can be timely processed and collected. By setting up a dust removal mechanism, the dust and particulate matter generated during the grinding and rust removal process can be greatly reduced, thereby reducing pollution to the surrounding environment, and can significantly reduce the dust concentration in the air, improve the air quality in the workplace, reduce the risk of respiratory diseases, and protect the health of workers.

[0007] Preferably, an arc-shaped filter screen is installed in the dust box, and the arc-shaped filter screen is arranged around the port of the exhaust pipe. When the device is used, the arc-shaped filter screen can be arranged to avoid blockage of the exhaust pipe port, thereby ensuring the normal progress of subsequent dust removal operations.

A second motor is installed on one of the vertical plates, and the output end of the second motor is connected to one end of the screw. During the grinding and rust removal process, the second motor is operated to rotate the screw, and with the cooperation of the T-shaped slide rail, the sliding seat drives the grinding mechanism and the dust removal mechanism to move synchronously, thereby enabling mobile grinding. At the same time, during the grinding and rust removal operation, the dust removal mechanism can follow the movement of the grinding mechanism in real time, and can collect the generated dust and particulate matter in time, thereby ensuring that the grinding area is always kept clean.

When the steel pipe is clamped and fixed, the steel pipe is first passed through the shell cover, and one end of the steel pipe is sleeved on the second rotating body. Then the first pneumatic cylinder is started to move the first rotating body to the other end of the steel pipe. The second pneumatic cylinder is operated to expand the resistance plate outward, so that the steel pipe can be fixed by resistance. By setting the rubber pad, the friction between the resistance plate and the inner wall of the steel pipe can be increased, so that the steel pipe can be clamped and fixed more firmly, which is convenient for the subsequent grinding and rust removal of the steel pipe.

[0013] 1. During the grinding and rust removal process, the utility model starts the negative pressure pump to extract the gas in the dust box through the suction pipe and discharge it through the exhaust pipe, so that the inside of the dust box is in a negative pressure state, so that a large amount of dust and particulate matter generated during the grinding and rust removal process can be sucked into the dust box through the dust suction pipe, so that the dust and particulate matter generated during the grinding and rust removal process can be processed and collected in time.

The dust is discharged through the exhaust pipe 16, so that the inside of the dust box 4 is in a negative pressure state, so that a large amount of dust and particulate matter generated in the grinding and rust removal process can be sucked into the dust box 4 through the dust suction pipe 7, so that the dust and particulate matter generated in the grinding and rust removal process can be timely processed and collected. By setting up a dust removal mechanism, the dust and particulate matter generated in the grinding and rust removal process can be greatly reduced, thereby reducing the pollution to the surrounding environment, and can significantly reduce the dust concentration in the air, improve the air quality in the workplace, reduce the risk of respiratory diseases, and protect the health of workers;

[0029] During the grinding and rust removal process, the second motor 23 is operated to rotate the screw 22, and with the cooperation of the T-shaped slide rail 2, the sliding seat 3 drives the grinding mechanism and the dust removal mechanism to move synchronously, so that mobile grinding can be performed.
