Technical Field
The invention relates to the field of railway transportation, in particular to a safety protection system and a safety protection method for handing over of a molten iron combined transport vehicle.
Background
Railway transportation refers to the transportation mode (definition) of running along a laying track using technical equipment such as locomotives, vehicles and the like. Railway transportation is a mode of transportation in which passengers and cargo are transported using railway trains. It plays an important role in the production process of social substances. It features large transportation quantity, fast speed, low cost, no limitation of weather condition, and suitability for long-distance transportation of bulk and heavy goods.
Unit carriers for transporting passengers, freight and for this purpose or for use in passenger and freight trains are in principle grouped on railway tracks. May be referred to simply as a "vehicle". Extracted from (GBT 45491.1-2004).
A locomotive is a self-propelled vehicle (locomotive definition) that operates in a train of tractive or push railcars without loading the commercial load itself. The locomotive or track tractor which has the traction capability and does not load business load and runs on the railway track with power, such as an electric locomotive, a diesel locomotive and the like, adopts manual driving and automatic driving;
the train consists of a plurality of powered vehicles (motor train units) and unpowered vehicles (trailers), and a group of trains which always run in a fixed marshalling mode and cannot be randomly changed in the normal service life cycle becomes a motor train unit (defined by the motor train unit). Vehicles with the capability of carrying commercial loads and having power drive and linked in group operation are called motor train units, such as: the railway passenger transport motor train unit, the freight transport motor train unit, the subway train, the light rail train and the tramcar adopt manned driving or unmanned automatic driving;
the single vehicle with power and no loading business load is called a rail vehicle, is mostly used for maintenance and repair operation of railways, and is generally driven by people at present.
The special railway line is introduced into a port trestle or the front edge of a wharf, a container ship loads a container berthing wharf, the quay bridge unloads the container ship, and a quay bridge crane directly transfers container cargos from the ship to a railway train or directly transfers the container cargos from the railway train to the ship without horizontal transportation equipment such as a transfer yard, an on-site collection truck and the like. The precise positioning of railway container vehicles is required in the automatic process of loading and unloading operation, the requirements of automatic control of the combined transportation and transportation of molten iron are met by adopting an applicable high-efficiency dynamic positioning method and error precision, and the main operation of the existing railway shunting locomotive is the loading and unloading operation between a station and a port and cannot meet the requirement of loading and unloading positioning precision of a shore bridge.

Therefore, a high-efficiency comprehensive transportation system for the combined transportation of molten iron is constructed. The railway shunting locomotive is used for taking and delivering a locomotive without an automatic control system, a pushing vehicle of the railway shunting locomotive enters a port loading and unloading line and then is unhooked, a rail tractor with an accurate positioning function is connected with a rear traction railway train to move forwards or backwards on a wharf at the front edge of a port, and the traction railway train is accurately positioned and moved on the wharf front edge to be matched with a shore bridge for quick loading and unloading operation. The container ship loads the container berthing wharf, the quay crane carries out loading and unloading ship operation on the container ship, and the quay crane directly transfers container cargos to a railway train from the ship or directly transfers the container cargos to the ship from the railway train, so that horizontal transportation equipment such as a transfer yard and an on-site collection truck is not needed, the transfer time of the container through transportation is shortened, and the operation benefit is improved.
