Description

Technical Field

[0001] The utility model belongs to the technical field of spraying devices, and in particular relates to a spraying device used for anti-corrosion and anti-rust treatment of seamless steel pipes. Background Art

[0002] Seamless steel pipes offer advantages such as high strength, good toughness, corrosion resistance, light weight, and impact resistance. They are a high-strength, high-toughness steel material that can be widely used in industries such as construction and machinery, and are particularly effective in treating steel structures and steel corrosion. Seamless steel pipes have excellent weathering and corrosion resistance, making them adaptable to use in diverse environments. The production of seamless steel pipes requires careful attention to detail, such as the treatment of the inner and outer walls of the pipes and the anti-corrosion treatment of the seamless steel pipes. Failure to do this properly can lead to severe corrosion or even unusability. Therefore, spraying equipment is required to ensure the corrosion resistance and waterproofing of seamless steel pipes.

[0003] However, the conventional device still has the following problems when used:

[0004] It is difficult for traditional spraying equipment to spray the inner and outer walls of seamless steel pipes at the same time. Some spraying equipment can only spray the outer wall of seamless steel pipes, which makes it difficult to meet the production needs of seamless steel pipes. It is also difficult to quickly transfer the seamless steel pipes after spraying, which is inconvenient for the next step of processing of the seamless steel pipes and has slow work efficiency. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide a spraying device for anti-corrosion and anti-rust treatment of seamless steel pipes, which has the advantages of being able to spray the inner and outer walls of seamless steel pipes at the same time and facilitating the transfer of seamless steel pipes after spraying.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A spraying device for anti-corrosion and anti-rust treatment of seamless steel pipes includes a conveying platform, a plurality of transmission rollers rotatably engaged between inner walls on both sides of the conveying platform, first rotating wheels installed at both ends of the transmission rollers, a transmission mechanism engaged with the first rotating wheels installed on one side of the conveying platform, and a steel pipe body installed on one side of the transmission rollers;

[0008] A rotating mechanism that cooperates with the steel pipe body is installed inside the conveying platform. Two working plates are installed on one side of the conveying platform. An external spraying mechanism that cooperates with the outer side of the steel pipe body is installed between the two working plates. A control box is installed at one end of the conveying platform, and an internal spraying mechanism that cooperates with the inner side of the pipe body is installed on one side of the control box.

[0009] Preferably: the transmission mechanism includes a support plate installed on one side of the conveying platform, a bidirectional motor is installed on the upper side of the support plate, the output end of the bidirectional motor is fixedly connected to the first rotating wheel away from the control box, and the transmission between the multiple first rotating wheels is coordinated with a first belt. Through the bidirectional motor and the first belt, when the bidirectional motor is working, it drives the first rotating wheel to rotate, and causes the multiple transmission rollers to rotate at the same time, transmits the steel pipe body on the transmission roller, and pushes the steel pipe body to move along the length direction of the conveying platform, which is convenient for spraying the steel pipe body and at the same time convenient for transferring the steel pipe body after spraying out of the conveying platform.

[0010] The transmission gear of the present invention is a gear which is connected with the gear to be transferred to the transmission gear of the present invention, and the gear is connected with the gear to be transferred to the transmission gear of the present invention.

[0011] Preferably: the external spraying mechanism includes a spraying ring installed between two working plates, a plurality of external nozzles matching the outer side of the steel pipe body are installed inside the spraying ring, a plurality of L-shaped rods are installed on one side of the spraying ring, and an outer brush plate matching the outer side of the steel pipe body is installed at one end of the L-shaped rod. The internal spraying mechanism includes an inner nozzle installed on one side of the control box, an inner nozzle is installed at one end of the inner nozzle, two connecting rods are installed on the circumference of the inner nozzle, and an inner brush plate matching the inner wall of the steel pipe body is installed at one end of the connecting rod. The length of the inner nozzle is consistent with the length of the steel pipe body, and the outer nozzle and the inner nozzle are both arc-shaped. The outer nozzle and the inner nozzle are used to facilitate the simultaneous spraying of the outer and inner walls of the steel pipe body, and the steel pipe body is rotated at the same time by cooperating with the rotating mechanism, so that the outer brush plate and the inner brush plate can evenly apply the sprayed steel pipe body, making the spraying more uniform and meeting the rust and corrosion prevention production requirements of seamless steel pipes.

[0012] Preferably: the peripheral side of the transmission roller is arranged in an arc shape, and a control device is installed on one side of the control box. The arc-shaped transmission roller can avoid the steel pipe body from being misaligned during spraying, which causes the outer brush plate and the inner brush plate to be unable to paint the steel pipe body. At the same time, the contact area between the transmission roller and the steel pipe body is increased, so that the transmission roller can better push the steel pipe body to move.

[0013] Compared with the prior art, the beneficial effects of the present invention are:
