[0013] Figure 2 It is the top view of Figure 1 . DETAILED DESCRIPTION

[0014] The utility model features and other related features are further explained in detail in the following by examples combined with drawings, so that the understanding of the same industry technical personnel is facilitated:

[0015] As shown in Figures 1-2 , the figure reference 1-13 respectively indicates for: fixed assembly 1, T type bolt 2, elastic strip 3, flat washer 4, nut 5, rail end baffle 6, buffer pad 7, track gauge pad 8, buffer pad 9, universal wheel 10, spring washer 11, spiral anchoring bolt 12, rail 13.

[0016] Example: as Figure 1 And Figure 2 Indicated, the rail short distance horizontal transportation track protection damage prevention device in this embodiment is used to carry out short distance horizontal transportation to rail 13.

[0017] Specifically, the device body in the embodiment includes fixed assembly 1, the lower four quarters of the fixed assembly 1 are respectively provided with universal wheel 10, the universal wheel 10 adopts replaceable 360 ° direction travel wear-resistant tire, so that fixed assembly 1 can move along the line direction smoothly, the universal wheel 10 can be further selected soft rubber tire, to realize the effect of silence.

[0018] In the embodiment, as Figure 1 Indicated, universal wheel 10 is fixed on fixed assembly 1 through spiral anchoring bolt 12, and spring washer 11 is arranged between the two, to reduce damping effect.

[0019] As Figure 1As shown, the rail 13 is fixedly installed on the fixed assembly 1 through the fastener to ensure the stability of the rail 13 during horizontal transportation. The fastener comprises a T-shaped bolt 2, a spring strip 3, a flat washer 4, a nut 5 and a gauge pad 8, wherein the gauge pad 8 is arranged on both sides of the rail 13, and the corresponding T-shaped bolt 2 is arranged at each gauge pad 8, each T-shaped bolt 2 is inverted and connected with the fixed assembly 1, the spring strip 3 is fixed and buckled through the cooperation between the T-shaped bolt 2 and the nut 5, and the spring strip 3 is pressed on the gauge pad 8.
