Description

Technical Field

[0001] This utility model relates to the field of rail cutting technology, specifically a rail cutting device for track construction that is easy to adjust. Background Technology

[0002] Steel rails are the main component of railway tracks. Their function is to guide the wheels of locomotives and rolling stock, bear the enormous pressure from the wheels, and transmit this pressure to the sleepers. Steel rails must provide the wheels with a continuous, smooth rolling surface with minimal resistance. In electrified railways or automatic block signaling sections, steel rails can also serve as track circuits.

[0003] During daily use, steel rails can suffer various types of damage, including wear, breakage, cracks, railhead damage, and cracks in rail web bolt holes. Therefore, during routine track maintenance, rails must be replaced to ensure safe train operation. This necessitates cutting the rails.

[0004] Existing handheld cutting devices are prone to instability during cutting, affecting the flatness of the cut surface. Therefore, a rail cutting device for track construction that is easy to adjust is proposed to facilitate the cutting of rails. Utility Model Content

The first motor 13 drives the second lead screw 12, which is guided by the second guide rod 10, thereby driving the movable seat 11 to move. The movable seat 11 drives the cutting wheel 15 to move via the L-shaped mounting plate 14. The second motor 16 drives the cutting wheel 15 to rotate, thus cutting the rail by moving and rotating the cutting wheel 15. The entire device is fixed on the rail and guided by the second guide rod 10, eliminating the need for manual handling or support, thereby improving the stability of the cutting and effectively increasing the flatness of the cut surface.

[0028] The first fixing mechanism 1 is connected to the second fixing mechanism 2 as a whole through the adjustment mechanism, so that the device can be fixed to two rails at the same time, thereby improving the stability of the device fixing.

[0038] The working principle of this utility model is as follows:

[0039] In use, the connecting seat 8 on the first fixing mechanism 1 slides on the extension connecting rod 19 to adjust the distance between the first fixing mechanism 1 and the second fixing mechanism 2. At the same time, it is fixed by the tightening bolt 20, so that the fixing clamps 3 on the first fixing mechanism 1 and the second fixing mechanism 2 are in contact with the rail. At this time, the handle 7 can be rotated to drive the first lead screw 6 to rotate. Under the guidance of the first guide rod 5, the movable clamp 4 approaches the fixed clamp 3 to clamp the rail. At this time, the locking nut 18 is tightened to squeeze the movable clamp 4 and strengthen the clamping state. At this time, the first motor 13 and the second motor 16 are started.
