The using method comprises the following steps:
when in use, the device is arranged on the outer side of the strand steel rail in the small radius curve. When the train passes through the track with a small curve radius, a transverse force is given to the T-shaped guard rail 1, the transverse force is transmitted to the double-head special-shaped bolt 10, the double-head special-shaped bolt 10 gives transverse pressure to the thickened round table type elastic rubber ring 9, the thickened round table type elastic rubber ring 9 deforms due to the pressure, and along with the increase of the pressure, the deformation is increased, and the rigidity is continuously increased to be smaller and smaller. And, the horizontal pressure of the circular truncated cone-shaped elastic rubber ring 9 of the thickening is transmitted to the upper support 6 of the guard rail, the upper support 6 of the guard rail is fixed with the triangular groove 4-1 of the lower support 4 of the guard rail through the triangular boss 6-1 at the tail end, the horizontal pressure born by the upper support 6 of the guard rail is effectively transmitted to the lower support 4 of the guard rail, the lower support 4 of the guard rail is fixed with the steel rail 12, and the horizontal force is transmitted to the railway track, so that the guard rail device and the railway track form a whole to increase the structural strength.
At this time, the stud bolts 10 inserted into the rail upper bracket 6 move to the left, and the nuts 7 threaded on the stud bolts 10 on the outer side of the rail upper bracket 6 also move to the left.
With the increase of the deformation of the thickened round table type elastic rubber ring 9, the thin-wall steel sleeve 11 starts to play a role, and the thickened round table type elastic rubber ring 9 is prevented from being deformed continuously, so that the rigidity is increased again. Therefore, when the train has no derailment risk, the abrasion of the outer rail can be stably reduced under the condition of reducing the abrasion wheel backs no matter the magnitude of the transverse force value. When the train has derailment risk, the movement amplitude of the T-shaped guard rail 1 is very large, the thickened round table type elastic rubber ring 9 in the thin-wall steel sleeve 11 is deformed too much at this time, the thin-wall steel sleeve 11 is prevented from being deformed continuously, and the guard rail device is close to a rigid body at this time, so that the train wheel pair can be prevented from being deflected continuously.
In addition, the spring 8 is not subjected to transverse force, and after the thin-wall steel sleeve 11 moves along with the deformation of the thickened round table type elastic rubber ring 9, the elastic force of the spring 8 can enable the thin-wall steel sleeve 11 to return to the initial position, so that the thickened round table type elastic rubber ring 9 is prevented from being corroded.
After the train passes, the thickened round table type elastic rubber ring 9 rebounds, and drives the stud bolt 10 to move rightwards through the round boss 10-1, so that the T-shaped guard rail 1 returns to the initial position, and meanwhile, the nut 7 threaded on the stud bolt 10 on the outer side of the guard rail upper bracket 6 also moves rightwards and abuts against the outer side of the guard rail upper bracket 6, so that the stud bolt 10 is prevented from moving rightwards further to fall off.
When the steel rail 12 is required to be maintained, the upper support 6 of the guard rail and the lower support 4 of the guard rail can be separated only by pulling out the bolt 5, so that a space is provided for maintenance.
