Adjustable device for railway to cross active faults

An adjustable device for railway to cross active faults, configured to fix a rail (1) and a sleeper (2), wherein the device comprises:

• a fastener mounting base (3), disposed between the rail (1) and the sleeper (2);
• clamping pipes (4), disposed between the fastener mounting base (3) and the sleeper (2), wherein the sleeper (2) is provided with a through groove (201), and the clamping pipes (4) are detachably fixed inside the through groove (201);
• control parts, disposed on inner walls of the clamping pipes (4) respectively, wherein each of the control parts is configured to detect lateral pressures between the fastener mounting base (3) and corresponding one of the clamping pipes (4), thereby to separate the corresponding one of the clamping pipes (4) from the through groove (201);
• wherein the clamping pipes (4) are detachably matched with the through groove (201) of the sleeper (2), thereby the rail (1) and the sleeper (2) are fixed again after a relative sliding;
• wherein each of the control parts comprises:
• pressure sensors (5) and an electromagnet (6), the pressure sensors (5) and the electromagnet (6) are fixed on the inner wall of the corresponding one of the clamping pipes (4), each of the pressure sensors (5) is configured to detect the pressure between the fastener mounting base (3) and the corresponding one of the clamping pipes (4), the pressure sensor (5) converts the pressure into an electrical signal and transmits the electrical signal to the electromagnet (6), and the electromagnet (6) is configured to control the corresponding one of the clamping pipes (4) to separate from the through groove (201).
