Description

Technical Field

[0001] The invention relates to the technical field of steel pipes, in particular to the technical field of steel pipe purging. Background Art

[0002] As my country's industrial development shifts from quantity to quality, steel pipes are increasingly used in industries such as petrochemicals, energy, medical care and aviation, and customers have higher and higher requirements for the delivery status of steel pipes. After straightening and grinding, steel pipes are prone to have attachments such as floating rust and iron oxide powder on their surfaces. If they are not removed by blowing or other methods, such impurities may accumulate in the gaps during subsequent processing and form defects such as slag inclusions and pores during welding, ultimately affecting the quality of the steel pipes leaving the factory.

[0003] At present, most factories use manual handheld nozzles to blow steel pipes; however, dust can easily spread in the workshop environment during the blowing period, which on the one hand causes serious pollution to the operating environment, and on the other hand affects the physical and mental health of workers; in addition, there are automatic blowing devices on the market, such as a steel pipe inner wall blowing device with announcement number CN204448726U; however, such devices often require the operator to assist in unloading after the blowing is completed or to be equipped with an additional unloading mechanism for electric unloading, and cannot directly unload the material step by step during the blowing period, resulting in relatively low work efficiency. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to provide a steel pipe purging device with a simple overall structure. It can not only clean impurities in the pipe, but also does not require manual unloading or the installation of an electric unloading mechanism.

[0005] To achieve the above-mentioned purpose, the present invention proposes a steel pipe purging device, including a purging mechanism, a transposition mechanism, a unloading mechanism, a main frame and a central controller. The purging mechanism has a nozzle and a guide wheel rotatably arranged on the periphery of the nozzle. The purging mechanism is driven by the transposition mechanism to make the nozzle and the guide wheel synchronously enter and exit the steel pipe horizontally placed on the main frame along the pipeline. The transposition mechanism is driven by the unloading mechanism to drive the steel pipe to roll along the main frame from the feeding end to the unloading end. The central controller is electrically connected to the purging mechanism, the transposition mechanism and the unloading mechanism respectively.

[0006] Preferably, the transposition mechanism includes a transposition substrate, a transposition motor, a transposition nut, a transposition screw rod, a transposition slider and a transposition track. The transposition motor and the transposition track are respectively fixed on the transposition substrate. The transposition nut is rotatably built into the transposition motor. The transposition screw rod horizontally penetrates the transposition motor and is threadedly connected to the transposition nut. The transposition slider is slidably connected to the transposition track and fixed to the transposition screw rod.

[0007] Preferably, the purging mechanism includes an air pipe, a nozzle, a guide wheel, a duct and a pressurizing device, one end of the air pipe is respectively equipped with a nozzle and a guide wheel and the other end is connected to the pressurizing device through the duct, and the air pipe is also fixed together with the transposition slider.

The unloading base plate is fixed to the main frame and is also equipped with the unloading motor, the unloading bracket and the unloading track. The unloading screw is rotatably connected to the unloading bracket and driven to rotate by the unloading motor. The unloading nut is threadedly connected to the unloading screw and can slide along the unloading track through the unloading slider. The unloading slider is fixed to the transposition base plate.

[0009] Preferably, the main frame includes a main supporting substrate and a main supporting base, the main supporting substrate is installed on the main supporting base and is provided with air leakage mesh holes, a fan is also installed above and / or below the main supporting substrate, and the central controller is electrically connected to the fan.

[0010] Preferably, a material blocking plate is further provided on the side of the main supporting substrate opposite to the transposition mechanism.

[0011] Preferably, it further comprises a sub-frame and an auxiliary feeding mechanism, wherein the sub-frame is arranged close to the feeding end of the main frame, and the auxiliary feeding mechanism is located between the sub-frame and the main frame and can transfer the steel pipes from the sub-frame to the main frame one by one.

[0012] Preferably, the sub-frame includes a sub-support substrate and a sub-support base, the sub-support substrate is installed on the sub-support base and is arranged lower than the main support substrate, the auxiliary loading mechanism includes a roller frame, a rotating roller, a loading motor and an electromagnet, the roller frame is installed between the main support base and the sub-support base, the rotating roller has a built-in electromagnet and is rotatably connected to the roller frame.

[0013] Beneficial effects of the present invention: 1) By combining the purge mechanism, the transposition mechanism, the unloading mechanism, the main frame and the central controller, the transposition mechanism can be used to drive the purge mechanism to synchronously extend the nozzle and the guide wheel along the pipeline into the steel pipe placed horizontally on the main frame. Then, while the nozzle is blowing the pipeline, the unloading mechanism is used to indirectly roll the steel pipe along the main frame from the feeding end to the unloading end to automatically complete the unloading. The overall structure is simple, which can not only realize the cleaning of impurities in the pipe, but also does not require manual unloading or the installation of an electric unloading mechanism; 2) A main support base plate with air leakage mesh holes and a main support base that elevates the main support base plate are used to form a main frame, and a fan is added above and / or below the main support base plate, so that the fan can be used to simultaneously blow the steel pipe externally while the steel pipe is rolling and being blown internally, so that the steel pipe can finally be cleaned of impurities both inside and outside; 3) By setting a sub-frame at the feeding end of the main frame, and setting an auxiliary feeding mechanism composed of a roller frame, a rotating roller, a feeding motor and an electromagnet between the main frame and the sub-frame, the steel pipes can be transferred one by one from the sub-frame to the main frame by turning on and off the electromagnet during the process of the feeding motor driving the rotating roller to rotate, thereby realizing automatic feeding of the steel pipes.
