Description

Rail for cutting cutting angle of rail cutter and rail cutter kit including the holder {Holder for adjusting cutting angle of rail cutter and rail cutter kit comprising the holder}

The present invention relates to a rail cutter, and more specifically, a rail cutter and a supporter to enable fine angle adjustment in a state in which a rail cutter used to cut a railroad rail for repairing a railroad rail is fixed to the rail by a fixed support. Rail cutting machine is installed between the cutting angle adjustment holder and the cutting angle adjustment rail including the holder.

In general, railway rails support the wheels to guide the driving resistance and the driving track of the wheels. The rails are mainly manufactured in an 'I'-shaped cross section protruding from the head part and the foot part.

Due to the constant load and external environmental factors of railroad cars, there is a constant need for maintenance and repair of railroad rails that are broken, deflected, warped, distorted, and twisted incorrectly. The situation is being done using manpower.

In particular, when a damage occurs in the connection portion of the rail is known rail cutting machine that can be repaired by inserting a new rail as much as the cut portion by cutting the damaged portion.

However, the rail cutter known to date has a problem that it is difficult to precisely match the rail and the right angle to the cutting edge of the rail cutter because it is not fine angle adjustment once it is fixed to the rail by a fixed support.
