Description

Pipe rotate device based on type I steel beam

The present invention relates to a pipe rotator for rotating a pipe for welding or cutting, and to a removable pipe rotator based on an I-type steel beam to be detachably used based on the I-type steel beam.

In heavy industry, chemical and shipbuilding industry, pipes are cut, processed and welded in order to use pipe piping materials, but in the past, the operator directly rotates the handle of the machine itself. In order to solve this uneven problem and to simplify the pipe processing work, a pipe rotator that rotates the pipe is used.

Pipe piping material is long and heavy, while the pipe is circular in cross section, so that the pipe is rotated at a constant speed and the cutting, welding, or processing is performed in order to process the pipe.

Existing pipe rotator adopts the method that the machine rotates along the pipe after cutting or fixing the oxygen or plasma cutting torch to the pipe with a band, so it takes a long time to install and secures space for the machine to rotate. Due to the inconvenience to use the situation is suffering from the use.

And, long pipes should be rotated in a horizontal state. Machines such as welding or cutting machine should be kept horizontal to the pipes, and cutting or welding should be made. In addition, there is a problem that it is difficult to rotate in a horizontal state, and also because the long length of the pipe to support one or two rollers far away from the machine, it was difficult to level with the roller and the machine.

In the present invention, in the welding or cutting operation while rotating the pipe, the pipe rotator can be simply installed horizontally while being rotated regardless of the diameter of the pipe, and the pipe is rotated at a constant speed by a motor. It is to make welding or cutting work.

The present invention makes it easy to install the pipe rotating device and the auxiliary roller by using the I-type steel beam, and the two rotary rollers and the guide rollers are installed in the pipe rotating device while the rotating rollers are rotated by the motor. It is made by changing between two rotary rollers in accordance with the diameter of the pipe placed between the rotary roller and the guide roller, so that the pipe is rotated by a constant speed with the rotary roller even if the pipe of any diameter is raised.

In particular, the present invention can be easily installed in a horizontal state by simply moving to be installed on the I-type steel beam, the rotary roller to rotate while supporting the pipe is rotated in the same direction by receiving the rotational force of the motor to the chain The gap between the rotating rollers is made by varying the diameter of the pipe.

The auxiliary roller of the present invention is installed only the rotating roller and the guide roller so that the smooth rotation is made in the state of supporting the pipe regardless of the pipe diameter.

In the present invention, since the pipe rotating device and the auxiliary roller are installed in the I-type steel beam, there is an advantage that the installation and movement are easy and can be used by adjusting the horizontal state. There is an advantage.

In addition, the present invention can be a constant speed rotation of the pipe in the support state, it is possible to ensure the quality when the pipe is cut or welded using an electric cutting grinder or oxygen and plasma cutting torch.
