[0002] The processing of spiral pipes generally uses professional machines to coil steel plates (or steel coils) into a spiral shape and then weld them into shape. However, in the actual work process, the steel plates may not be processed in time after being transported to the company.

[0003] Steel plates are exposed to the air for a long time, such as being placed in the enterprise in the form of rolls, which can easily cause rust on the side of the steel plates. Therefore, rust removal is required before the spiral tube is welded and formed. For example, the patent: Rust removal device for spiral tube making machine, application number: CN201020549317.8, has circular steel brushes driven by motors at the upper and lower parts of the positions where the edges of the steel plates on both sides of the input cavity pass. The steel brushes need to be driven by four motors at the same time for rust removal, which has the problems of high equipment cost, large space occupied by equipment installation, and inconvenient use. Utility Model Content

[0004] The embodiment of the present application provides a spiral tube welding rust removal device, which can simultaneously remove rust on both sides of a steel plate by driving a wire brush with two motors. At the same time, after the wire brush is worn, based on the hinged relationship formed between the motor and the mounting part, the wire brush slightly tilts downward and can still continue to remove rust on the side of the steel plate. The use is very convenient and can also reduce equipment costs and reduce the space occupied by the equipment.

[0005] An embodiment of the present application provides a spiral tube welding rust removal device, which is used to remove rust on the side of a steel plate before spiral tube welding. The spiral tube welding rust removal device includes mounting parts vertically symmetrically arranged on both sides of a spiral tube welding assembly line and motors correspondingly installed on the mounting parts, wherein a wire brush is installed on the output shaft end of the motor, and the base of the motor is hinged to the mounting part through a pin shaft, so that in the process of the wire brush contacting the steel plate to be welded, the wire brush can gradually tilt downward as the wire brush wears without losing contact with the steel plate to be welded.

[0006] In a possible implementation manner, the mounting member is implemented as a channel steel, and the opening of the mounting member is located at the bottom.

[0007] In a possible implementation, the mounting member is evenly provided with a plurality of positioning holes matched with the pin shaft in the length direction.

[0008] In a possible implementation, the spiral tube welding rust removal device further includes a counterweight, and the counterweight is connected to the motor to increase the weight of the motor on the inner side of the pin shaft.

[0009] In one possible implementation, the counterweight member includes a protective cover and a counterweight block, wherein the protective cover is disposed on the motor and covers the top and sides of the motor at the same time, wherein the counterweight block is symmetrically connected to both sides of the protective cover, i.e., both sides of the motor.

[0010] In a possible implementation, a clearance gap is formed at the bottom of the protective cover at one end close to the steel plate to be welded.

[0011] Beneficial effect: Compared with the prior art, the spiral tube welding rust removal device provided by the present application is provided with mounting parts on both sides of the spiral tube welding assembly line, and a motor is connected to the mounting parts in a hinged manner. In the initial state, the wire brush at the output shaft end of the motor is basically facing the steel plate to remove rust from the steel plate. After long-term use, as the wire brush wears, the wire brush at the output shaft end of the motor gradually tilts downward, and the rust removal can be continued through the wire brush close to the upper part, thereby extending the service life of the wire brush for wearing parts to a certain extent. When the wire brush is replaced with a new one after being used for a period of time, the equipment cost can be effectively reduced, the rust removal quality can be ensured, and the equipment occupies a small space and is easy to use.

[0012] These and other purposes, features and advantages of the present invention are fully reflected in the following detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] refer to Figure 1 , the embodiment of the present application provides a spiral tube welding rust removal device, which is used to remove rust on the side of the steel plate before spiral tube welding. The spiral tube welding rust removal device includes a mounting member 10 vertically symmetrically arranged on both sides of the spiral tube welding assembly line and a motor 20 correspondingly installed on the mounting member 10, wherein a wire brush 30 is installed on the output shaft end of the motor 20, and at the same time, the base 21 of the motor 20 is hinged to the mounting member 10 through a pin shaft 22, so that in the process of the wire brush 30 contacting the steel plate to be welded, as the wire brush 30 wears, the wire brush 30 can gradually tilt downward without losing contact with the steel plate to be welded. In this way, under normal circumstances, the motor 20 drives the wire brush 30 to basically face the side of the steel plate to remove rust from the steel plate. After long-term use, as the wire brush 30 is worn, the wire brush 30 can gradually tilt downward without losing contact with the steel plate to be welded. As the amount of wear on the brush 30 increases gradually, under the hinged action of the pin shaft 22, the output shaft end of the motor 20 and the wire brush 30 gradually tilt downward, and the rust removal treatment continues to be performed by relying on the upper part of the wire brush 30, which can extend the service life of the vulnerable wire brush 30 to a certain extent. After the wire brush 30 continues to be used for a period of time, the staff will replace it with a new wire brush, which is easy to use. At the same time, it can also avoid the problem that the wire brush 30 maintained in a fixed position cannot be properly rusted after wear. Therefore, the spiral tube rust removal device provided in the present application can ensure the quality of rust removal.
