Background
The railway contact net maintenance vehicle is a common railway maintenance vehicle type and is used for checking problems existing in contact nets and timely repairing the problems so as to guarantee safe operation activities of railway operation. The operation object of a railway maintenance operation platform (a contact network maintenance vehicle) is a railway power supply network, and an operator is generally required to climb to an aerial operation platform to detect the problems of the contact network, so that the operation risk is high, and the safety factor of the railway maintenance operation platform is required to be high.
At present, the contact network overhaul platform at home and abroad mainly comprises two types, namely a large-scale engineering machinery contact network overhaul vehicle with power and a simple sheet-mounted contact network overhaul vehicle without power.
The maintenance vehicle for the contact net of the large-scale engineering machinery is high in cost, large in number of operators (requiring 8-10 operators to work simultaneously), high in safety level of operation requirements, not easy to detach due to the fact that the vehicle is of a fixed structure, only capable of being transported and moved by power of the vehicle, and incapable of flexibly and quickly processing sudden faults of the contact net on the line. Therefore, such vehicle models are currently limited to a small range of use.
The simple sheet-mounted maintenance vehicle widely used at present is a fixing structure of a simple sheet-mounted operation platform, and also has the technical problems that long-distance maintenance cannot be carried out without configuring a power module, more parts are needed, more time is consumed for assembly, and the modularization degree is low. Meanwhile, the simple sheet-mounted maintenance vehicle does not have a manned function, is poor in operation comfort, cannot reduce the height during inspection, is low in safety performance, needs 2 persons for maintenance and 4 persons for support during operation, is low in working efficiency, and cannot adapt to the technical problems of rapid processing requirements of sudden faults in a long tunnel when the vehicle advances by manual push-pull.
At present, the ladder frame of the widely used ladder car which is a simple piece-mounted ladder car is of a fixed structure, a power module is not configured, long-distance maintenance cannot be carried out, the number of parts is large, the assembly is time-consuming, the problem of low modularization degree exists, and the ladder car can not adapt to the requirement of rapid processing of sudden faults in a long tunnel when going forward by manual pushing and pulling.
Therefore, in the prior art, a relatively ideal railway maintenance operation platform which is simple in structure, light in weight, few in operation personnel and convenient to transport manually and meets the requirements of maneuvering, flexible and rapid processing of sudden faults of a contact network and personnel carrying does not exist.
