Detailed Description
The present invention will be described in further detail with reference to the drawings and embodiments. The features and advantages of the present invention will become more apparent from the following description.
In which, although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.
The utility model provides a longitudinal sleeper system with a maintenance system, which comprises a sleeper body 1 and a damping pad 2 arranged at the bottom of the sleeper body 1, wherein the damping pad 2 is laid on a track bed 9, as shown in figures 1 and 3,
the sleeper body 1 is provided with a vertically through grouting hole 11,
the damping pad 2 is provided with a through hole 21 at a position corresponding to the grouting hole 11.
When empty hanging, as shown in fig. 2, grouting is performed on the lower area of the vibration damping pad 2 through the grouting holes 11 and the through holes 21, so that the hollow area can be filled, and then repairing is completed.
In a preferred embodiment, the system further comprises a sealing plug 12, wherein the sealing plug 12 is arranged in the grouting hole 11, and protects the grouting hole 11 when the sleeper is not hung empty, so that sundries are prevented from entering the grouting hole 11 and further blocking the grouting hole 11.
In a preferred embodiment, the system further comprises a pressure sensor 3, the pressure sensor 3 is placed in the grouting hole 11 and is positioned at the lower part of the sealing plug 12, and a spring 4 is arranged between the pressure sensor 3 and the sealing plug 12, so that the pressure sensor 3 and the track bed 9 have pressure.
When a train passes above the sleeper body 1, the sleeper body 1 can press down the damping pad 2, so that the damping pad 2 slightly sinks by 1-2mm, at the moment, the spring 4 can protect the pressure sensor 3, and the sealing bolt 12 is prevented from being directly in hard contact with the pressure sensor 3 to cause the pressure sensor 3 to be extruded and damaged.
According to the utility model, the pressure sensor 3 detects pressure discontinuously, and when the pressure values detected twice are not obviously changed, namely the fluctuation is lower than the set threshold value, the empty hanging phenomenon is not generated; when the pressure values detected in two adjacent times fluctuate greatly and exceed a set threshold value, the spring force is changed greatly, namely the distance from the bottom of the sealing bolt 12 to the top of the ballast bed 9 is changed, so that the pressure is changed, and the empty hanging phenomenon is likely to occur at the moment.
