Because the tower wagon height is higher, when the operation of railway bend, has the unstability risk, the railway is overhead contact net construction operation with the tower wagon accident emergence occasionally, the tower wagon topples and often produces serious consequences such as personal injury and death. At present, the rail clamping device of the contact net operation tower wagon can only be used when the tower wagon operates statically, and the rail clamping device must be taken down from a steel rail in the advancing process of the tower wagon. Therefore, the ladder car has no anti-overturning measure in the advancing process, and people pushing the ladder car completely lean against the bottom of the ladder car to prevent the ladder car from overturning. In the field construction process, the ladder car frequently travels under the condition that operators are on the top, for example, when the distance between the hanging strings is 8-12 meters, the operators on the top cannot frequently get on or off the ladder car. When the ladder truck works in a straight line section, the ladder truck is in a vertical state because the inner rail and the outer rail are on the same horizontal plane, and overturning accidents are not easy to happen. However, in the curve section, because the inner rail and the outer rail have height difference, and the smaller the curve, the higher the speed, the larger the height difference of the inner rail and the outer rail, the ladder car can move in an inclined state under the condition, and the overturn accident is easy to happen. If during the curve operation, the ladder car personnel can only advance after getting on or off the ladder car, will influence the efficiency of construction to a great extent, and site operation personnel often do not get on or off the ladder car in order to improve construction speed, bring serious potential safety hazard for site operation.
