Description

Intelligent rigid contact net maintenance ladder car Technical Field The utility model belongs to the technical field of maintenance equipment of rigid contact networks, and particularly relates to an intelligent maintenance ladder car for a rigid contact network. Background The rigid contact net is an important component of a rail transit power supply system, and the rigid metal structure is used for directly transmitting electric energy to an electric locomotive or a subway train. With the continuous running of the train, the contact line surface clamped by the rigid contact net is easy to wear, so that the stability of a power supply system can be affected, and equipment faults and potential safety hazards can be caused. Therefore, the regular maintenance of the rigid contact net is a key measure for ensuring the normal operation of the power supply system. And the traditional rigid contact net maintenance mode is manually polished and maintained. The process requires a ladder truck to be used for ascending, and maintenance personnel are required to polish the ladder truck along the direction of the contact line by using coarse sand paper and fine sand paper to finish polishing and polishing. The process has the advantages of high operation intensity, unstable manual polishing pressure, poor polishing effect caused by too low polishing pressure, low polishing efficiency caused by repeated polishing at the same position, excessive polishing caused by too high polishing pressure, reduced contact line service life, influence on bow-net coupling relationship, and influence on train operation stability. And there is certain potential safety hazard in the maintenance process, the contact line has burrs and can cut maintainers, a large amount of metal particles and dust that produce in the polishing process, and the inhalation can seriously influence healthy when maintainers work. In addition, an anchor section and a pull-out value position section are present in the rigid contact line. The anchor section is a section which divides the contact net into a certain length along the line and has independent mechanical stability structurally, and the two bus bars of the anchor section are connected with each other in a staggered manner at the joint so as to achieve the effect of smooth joint of the pantograph. The pull-out value refers to a certain offset between the contact line and the center of the pantograph slide plate of the electric locomotive at a locating point on a line according to technical requirements in order to ensure that the pantograph and the contact line are reliably contacted, are not off-line and ensure that the abrasion of the pantograph is uniform in the rigid contact net. The anchor section and the pull-out value section increase the working strength of the manual maintenance contact net, the individual positions cannot be manually maintained, only the mode of replacing the whole contact line can be selected, the maintenance cost of the rigid contact net is increased, and the maintenance efficiency is reduced. The problem that the contact wire is eccentric in the use process of the rigid contact wire is one of the common problems, and the contact wire is in uneven contact with a carbon sliding plate of a pantograph, so that one side of the contact wire is seriously worn, and the other side of the contact wire is worn slightly, which can cause the change of the geometric shape of the contact wire, and influence the service life of the contact wire and the stability and reliability of power supply. When the contact line is eccentric, the contact line needs to be manually polished again for maintenance, the geometric shape of the contact line is restored to be circular arc, and the phenomenon of sharp edges between the contact line and the carbon sliding plate is prevented from influencing the bow net relation. The eccentric wear problem not only increases the working difficulty of manual maintenance, but also increases the polishing pressure regulation and control difficulty during maintenance, and the individual eccentric wear positions are more severe, so that the manual recovery effect is poor.
