[Problems to be solved by the device]

 However, the cleaning process and the drying process of the pipe end threaded portion, which are performed before the above-mentioned inspection, are usually separated, and if the pipe end threaded portion is subjected to the inspection process after these steps, it leads to the inspection process. It took a considerable amount of time until the end, and as a result, the work efficiency in the process of inspecting the pipe end thread was significantly reduced.

By the way, since recent high-speed threading machines have extremely high threading workability, one inspector can perform all the cleaning, drying and inspection of the pipe end thread on this line. If we try to do so, we will not be able to meet the cycle time of the above thread cutting machine, and we will not be able to achieve the desired work efficiency.

Within the cycle time of the above threading machine, in order to smoothly perform all the cleaning, drying and inspection of the pipe end thread portion and achieve the desired work efficiency, the pipe end thread portion should be cleaned and cleaned. This can be achieved by deploying a total of two people, one as a dedicated staff for the drying work and one as a dedicated staff for the subsequent inspection work, but the inconvenience of increasing the number of staff, reducing labor, and anti-rationalization is there.

The present invention has been made in view of the above problems, and in order to perform inspection of the pipe end threaded portion efficiently and efficiently, cleaning and drying of the pipe end threaded portion are continuously performed in the same device. It is an object of the present invention to provide a washing / drying device for a pipe end threaded portion that can be used in the above.

[0008]

[Issue to achieve the task]

 In order to achieve the above object, in the pipe end thread cleaning and drying device according to the present invention, a base that is supported so as to be able to move up and down with respect to the installation surface and a back and forth movable device that is mounted on this base are installed. It is composed of a moving carriage and a washing / drying unit mounted on the moving carriage.The above-mentioned washing / drying unit sprays washing water inwardly when the moving truck is moved forward to carry in the steel pipe. A ring nozzle for spraying cleaning liquid that can clean the pipe end thread part of the steel pipe, and when the steel pipe is carried out by retracting the moving carriage, air is sprayed inward to inject the pipe end screw part of the above steel pipe. Air blow ring nozzles that can dry the outer surface and the ring nozzles are installed so as to penetrate in the axial direction of the ring nozzles.When moving the carriage back and out the steel pipe, air is sprayed. It is now possible to dry the inner surface of the pipe end thread. Is characterized in that a linear nozzle Buro.

[0009]

[Action]

 Thus, according to the present invention, the washing / drying unit for washing and drying the pipe end screw portion is mounted on the movable carriage, and the base supporting the movable carriage so as to be movable back and forth can be moved up and down with respect to the installation surface. Since it is supported by, the height can be adjusted to match the height position of the pipe end thread portion of the steel pipe to be washed and dried, and washing and drying can be performed.

Since the movable carriage is arranged so as to be movable back and forth on the base, by moving the movable carriage forward, the pipe end ridge portion of the steel pipe is installed in the cleaning / drying unit mounted on the movable carriage. It is possible to carry in and wash the pipe end thread part by injecting the washing water inward from the washing liquid jet ring nozzle.

Next, after cleaning the pipe end screw part, when the moving carriage is retracted to carry out the steel pipe, air is jetted inward from the air blow ring nozzle and the linear nozzle for air blow is used. Since the air is jetted outward from the inside, the jetting of these air dries both the inner and outer surfaces of the pipe end threaded portion.

As described above, the cleaning and drying of the pipe end thread portion are performed in series in the same apparatus, so that the work efficiency is improved, and therefore the subsequent inspection work can be efficiently performed.
