Intelligent unhooking system for railroad freight transportation and method

Abstract

The invention provides an automatic unhooking system for a draw gear connected with a disassembled carriage during railroad freight transportation and a method. The system comprises a data center, a client side, a site monitoring unit, a sensing device and an unhooking robot. During work, the site monitoring unit is in real-time communication with the data center, information such as disassembly operation notice orders and locomotive parameters is obtained through a comprehensive automation system interface of a marshalling station, the information collected by the sensing device is analyzed,an unhooking instruction is transmitted to the unhooking robot, and then all units of the unhooking robot cooperate to complete an unhooking task. The automatic unhooking system is ingenious in idea,reasonable in structure, convenient to use, flexible to adjust, high in universality and easy to maintain, the working efficiency of the marshalling station during railroad freight transportation is obviously improved, and the automatic unhooking system can be widely applied to various kinds of electrified railway construction.

Description

technical field [0001] This patent relates to the technical field of reorganization of railway freight carriages, in particular to a system and method for realizing the automatic decoupling of couplers connected to disassembled carriages in a railway freight hump marshalling station. Background technique [0002] In the prior art, the decoupling work in the freight marshalling station is done manually. According to the requirements of the work sheet, the decoupling staff will record the number of carriages passing by random cars while walking, find a suitable decoupling position based on experience, and hold the decoupling by hand. The handle lifts the knuckle pin, so that the compressed coupler is automatically opened under the drive of the coupler's own gravity, and the decoupling work is completed. [0003] There are many disadvantages in manual decoupling, such as complex working conditions and high labor intensity. Considering factors such as personal safety limits, the...

Problems solved by technology

[0003] There are many disadvantages in manual decoupling, such as complex working conditions and high labor intensity. Considering factors such as personal safety limits, the maximum pushing speed of the disintegrated train can only reach 6-7km / h, which limits the further improvement of the working efficiency of the hump marshalling station ; Especially in bad weather such as wind, frost, rain, snow, fog, etc., it is easy to cause the work sheet to be stained and lost. Coupled with the tense work of the personnel, the wrong number of carriages, the wrong sorting of disintegrated carriages, and the slipping and encoding sequence often occur Inconsistency with the reservation plan, etc., resulting in wrong hooks and missing hooks, which further lead to safety accidents; in order to eliminate mistakes such as wrong hooks and missing hooks, it is necessary to mobilize other staff in relevant positions to assist in finding the wrong hooked compartment and pull back the push button again. The grouping operation is carried out on the peak section, which reduces the efficiency of hump disintegration
