By rotating the crank 33, the adjusting screw 32 drives the mounting seat 34 to approach the tire, and then the turntable 36 contacts the tire, thereby improving the stability of the locomotive braking detection and preventing the locomotive from running off the track.

[0035] The slope protection 2 includes a triangular plate 21, two sets of side blocks 22 are fixedly connected to both sides of the triangular plate 21, and fixing bolts 24 are inserted into one side of the two sets of side blocks 22.

[0037] When in use, the tire of the locomotive is located on the locomotive brake roller 75 and the auxiliary roller 76. The crank 33 is turned to make the adjusting screw 32 drive the mounting seat 34 close to the tire, so that the turntable 36 contacts the tire, limits the locomotive and prevents the detection from deviation. The dual-axis motor 81 drives the rotating shaft 82 to drive the driving gear 84 to engage the driven gear 96, so that the transmission screw 97 drives the fixing block 94 to move on the guide rod 98, and then the hot air box 93 moves back and forth along the locomotive brake roller 75. At the same time, the hot air generated by the hot air blower 91 is passed into the hot air box 93 through the heat-conducting hose 92, and then blown onto the locomotive brake roller 75 through the air outlet 95 on the hot air box 93, so as to melt the frost on the locomotive brake roller 75, thereby facilitating the locomotive brake detection and improving the detection efficiency.
