the bottom of each side structure at two sides comprises a limiting system (8), each limiting system (8) comprises a sliding seat (81) and a sliding rail (82), each sliding rail (82) is positioned in a groove of each sliding seat, so that the middle structure and the side structures at two sides are positioned in a same line, the sliding seats (81) and the sliding rails (82) are integrally cast below the middle structure and cannot move, and the side structures and the sliding seats (81) integrated with the side structures can move along the sliding rails (82);
the subsequent protocol is any one of the following:
A. the two sides of the side structure respectively comprise a groove, and the grooves on the two sides are respectively an outer extrusion groove (4) and an inner extrusion groove (5); when internal extrusion is carried out, the motor (11) drives the extrusion bevel gear and the horizontal threaded shaft (9) to rotate so as to further drive the side structure to extrude outwards, the outer extrusion groove (4) can be extruded on the inward surface (19) of the rail, when external extrusion is carried out, the motor (11) drives the extrusion bevel gear and the horizontal threaded shaft (9) to rotate so as to further drive the side structure to extrude inwards, the inner extrusion groove (5) can be extruded on the outward surface (21) of the rail, and the extrusion groove (5) and the middle groove (7) extrude the rail body together;
B. the side structure outwards comprises an extrusion protrusion (22), the other side of the side structure comprises an inner extrusion groove (5), when external extrusion is carried out, the motor (11) drives the extrusion bevel gear and the horizontal threaded shaft (9) to rotate so as to further drive the side structure to inwards extrude, the inner extrusion groove (5) can extrude the rail outwards (21), and the extrusion groove (5) and the middle groove (7) extrude the rail body together; when internal extrusion is carried out, the motor (11) drives the extrusion bevel gear and the horizontal threaded shaft (9) to rotate so as to further drive the side structure to extrude inwards, and the extrusion bulge (22) can be matched with the inwards-facing surface (19) of the rail to realize the internal extrusion;
the shell with the upward middle structure comprises a jack groove (12) in which a jack can be placed; the jack is upward and can support the wheel-shaft;
combining any one of the tools, adopting an external extrusion mode in the scheme A or B, and tensioning the rails on two sides by the side structures on two sides; a force sensor is arranged on the horizontal threaded shaft (9), when the pulling force is too large or too small, the situation that the railway is extruded or pulled by external force is judged, and a debris flow system is warned.
10. A method of providing a railway warning as claimed in claim 9 wherein the force sensors are connected to a remote system via internet of things communication, the remote system being capable of monitoring the magnitude of the force at any time and providing a warning of an abnormally large force.
