Method of Making Steel Railway Sleepers

At present, wooden sleepers and disposable cement sleepers for fixing rail track are easy to damage and inconvenient to install. Such disadvantages as destroying resources and consuming energy are not conducive to the development of energy conservation and emission reduction in China.

In order to solve the problems of wood sleepers and one-time cement sleepers with fixed rail track, such as easy damage, inconvenient installation, resource damage, energy consumption and so on, the utility model provides one kind of Steel Railway Sleepers.

The train sleeper provided by the utility model includes a special-shaped I-beam, a C-type rail clamp base, a knife tooth inclined iron, a rubber pad and a track, which is characterized in that the lower leg width of the special-shaped I-beam is larger than the upper leg width. The C-type rail clamp base is provided with an upward C-shaped flanging, wherein one flanging is higher than the other flanging, and the higher flanging is provided with a fixed hole, and the C-type rail clamp base is welded on the upper end face of the special I-shaped steel in pairs. The rubber pad is located in the clamping groove of the C-type rail clamp base, and the track is located on the rubber pad. The bottom end of the rail is fixed in the clamping groove of the base of the C-type rail clamping device by a knife tooth angle iron. Further, the cutter tooth angle iron can be locked by a fastening pin.

Specifically, the fastening pin is located in the fixing hole on the base of the C-type rail clamping device, one side of the knife tooth angle iron is provided with a tooth shaped seaming groove, and the fastening pin is engaged with the tooth shaped seaming groove of the knife tooth angle iron. The cutter tooth inclined iron can also be locked in the following ways. The part of the front end of the cutter tooth inclined iron beyond the base of the C-type rail clamp and the special-shaped I-steel is provided with a fixing hole. The spring cylindrical pin is located in the fixing hole of the cutter tooth inclined iron, and the spring cylindrical pin is connected with the base of the C-type rail clamp and the special-shaped I-steel. Thus, the utility model can effectively prevent the loosening and falling out of the inclined iron, and has a constant clamping force on the rail, and prevents the movement of the rail and the sleeper. Because the utility model adopts the special-shaped I-beam, the bottom contact area is increased, and the pressure of the track on the ground is effectively reduced. Specifically, the width of the lower leg of the shaped I-beam can be 1.5 times that of the upper leg. The Steel Railway Sleepers of the utility model have the advantages of simple structure, firm reliability, convenient installation and disassembly, accurate gauge, reusable, etc. It helps the mine completely end the era of using wooden sleepers and disposable cement sleepers. In line with the environmental protection requirements of China's low-carbon economy, it saves valuable wood resources for the country and reduces the labor intensity of workers.
