In this example, the front side fixedly connected with anticreep piece 19 of arrester 17, the inner wall and the connecting wire 7 fixed connection of anticreep piece 19 can avoid connecting wire 7 because often being pulled off the disconnection that leads to connecting wire 7 and arrester 17 through setting up anticreep piece 19.

In this example, the bottom fixedly connected with stopper 21 of slide bar 901, the top fixedly connected with stabilizing block 20 of guide rail 2, the top and the square 1 fixed connection of pipe of stabilizing block 20 can avoid the slider 902 on the slide bar 901 landing from slide bar 901 through setting up stopper 21, and the stabilizing block 20 through setting up is connected square 1 and guide rail 2 for the structure is more stable.

It should be noted that the invention is a signal collecting device special for rail transit, first, connect the connecting wire 7 and the equipment wire 10, and make it more stable and difficult to break through the stabilizing mechanism 12, the two left half hoops 1201 and the right half hoop 1204 are sleeved outside the equipment wire 10 and the connecting wire 7, and the right half hoop 1204 is screwed in through the fixing screw 1207 to make its position fixed and avoid sliding, the equal length rod 1202 can limit the length of the connecting place of the connecting wire 7 and the equipment wire 10, install the equipment inside the carriage, when in normal use, the controller 405 controls the stepping motor 404 to rotate slowly, drive the rail wheel 401 to rotate, make it move back and forth along the guide rail 2, and collect the video image information through the video collecting camera 5, and the circuit of the device is rolled up through the rolling mechanism 9, when the connecting wire 7 is redundant, the balancing weight block 904 falls with the sliding block, and straighten connecting wire 7, when slide mechanism 4 was close to winding mechanism 9, can drag connecting wire 7 to the direction of self removal, connecting wire 7 can slide along second pulley 903 this moment, pulls the slider 902 simultaneously and rises for connecting wire 7 remains the state of flare-outing throughout.

While the invention has been described above with reference to an embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the various features of the disclosed embodiments of the invention may be used in any combination, provided that no structural conflict exists, and the combinations are not exhaustively described in this specification merely for the sake of brevity and resource conservation. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
