When it moves to the position of the contact network that needs to be repaired, compressed gas is produced by the air pump 2 and transported to the cylinder 4 along the air pipe 3. At this time, the manual control switch 10 is used to make the cylinder 4 work. The cylinder 4 pulls the pull rod 6 upward, driving the connecting rod 7 to merge the two clamps 8 and clamp them on the track 13, thereby fixing the entire device on the track 13 to prevent the vehicle from slipping or tilting and collapsing. When the pull rod 6 moves downward, the clamp 8 will open and be unlocked. After a period of use, the solar panel 14 will It is easy to be damaged and needs to be replaced in time. First, pull the rod 16 to drive the baffle 17 to compress the spring 18. At the same time, the rod 16 is separated from the solar panel 14 and retracted into the shell 15. At this time, the skateboard 12 automatically falls into the shell 15 due to gravity, blocking the exit of the rod 16. Then the solar panel 14 is removed and replaced and reinserted into the ladder frame 1. At this time, the skateboard 12 is lifted under the limit of the limit plate 19, and the spring 18 will immediately push the baffle 17, driving the rod 16 to reset and pop out, and reinsert it into the solar panel 14 to achieve fixation. The whole operation saves time and effort, and effectively improves work efficiency.
