Embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used to explain the utility model, is not to be used to limit scope of the present utility model.
The utility model railway bed cable trough adopts thermoplastic or thermoplastic composite to make, and adopts the railway bed cable trough of this material, in light weight, easy construction, mechanical property and good endurance, smooth, coefficient of friction is low, therefore meet the growth requirement that modern railways is built.
Describe the structure of a kind of embodiment of the utility model below in detail.
As shown in Figure 1, the railway bed cable trough comprises cell body 10, described cell body 10 have base plate 1 and about two sidewalls 2, cell body 10 inside also are provided with dividing plate 3.Two Room about dividing plate 3 is divided into cell body are respectively applied for and lay power transmission cable and communicaton and signal cable.Power transmission cable and communicaton and signal cable are separated by dividing plate 3, significantly do not disturb each other.According to on-the-spot needs, the Room near the railway side in the cell body 10 is wide than another chamber, and communicaton and signal cable is located at this near railway one side, and power transmission cable is located at opposite side.
The bottom surface of cell body 10 inside, promptly the upper surface of base plate 1 is the inclined-plane, and it is near a lateral deviation height of railway, and gradient is 0～5 °.With reference to Fig. 1, Fig. 2, the sidewall 2 of base plate 1 side on the low side and the bottom of dividing plate 3 are provided with spilled water hole 4.The rainwater that helps like this entering in the cell body 10 is discharged smoothly, can not gather too much immersion cable cable is caused damage.
The two ends of cell body 10 are respectively equipped with the tenon 5 of protrusion and recessed mortise 6.With reference to Fig. 2, Fig. 3, Fig. 4, tenon 5 and mortise 6 are separately positioned on the two ends of cell body base plate 1 and sidewall 2, and each cable trough connects from beginning to end during installation, and the tenon 5 of previous cable trough and the mortise 6 of next cable trough dock mutually, form good fit.
