Description

Accurate alignment and efficient exhaust operation method for wagon of wagon dumper Technical Field The invention belongs to the technical field of production scheduling of railway transportation and metallurgical enterprises, and particularly relates to an operation method for accurate alignment and efficient exhaust of a turning-over locomotive skin, which is particularly suitable for railway shunting operation of a raw material transportation line of a steel enterprise. Background In the operation of the existing car dumper, the conventional decentralized operation mode is generally adopted in the air exhaust, pipe removal, hook jump prevention operation of a car wagon and the alignment process of a locomotive, so that the problems of complex operation flow, long time consumption and low alignment precision exist. Taking a typical 22 mineral powder wagon as an example, the traditional car-by-car air exhaust mode takes about 20 minutes, the overall efficiency of the car turning operation is seriously affected, the fuel consumption of the locomotive is increased, and equipment abrasion and operation safety risks are not easy to cause due to inaccurate alignment. Therefore, a systematic, efficient and high-precision method for handling and aligning the skin of a car dumper is needed to solve the above-mentioned problems. Disclosure of Invention The invention aims to solve the technical problems of complex operation flow, long time consumption and low alignment precision of the traditional decentralized operation mode. In order to solve the problems, the technical scheme of the invention is that the control method for dry dedusting and explosion venting of the converter comprises the following steps: 1. Preparation stage of train wagon (1) Finishing the marshalling of the mineral powder wagon required by the wagon tipper at a marshalling station, and dragging or jacking the mineral powder wagon to a designated working line by the wagon; (2) And (5) checking the train wagon by factory inspection personnel, and commanding the locomotive trailer by a shunting operator after the train wagon is qualified. 2. High-efficiency integrated exhaust, pipe picking and hook jumping prevention operation (1) The centralized air exhaust is carried out, namely the pre-turning car train is arranged into a preparation stock way in advance, the centralized and quick air exhaust is carried out on the auxiliary air cylinders of the whole car, namely the air exhaust of the air exhaust pull rod of each car is carried out for 4-6 seconds, and the fact that the auxiliary air cylinder piston is completely retracted and the car is completely relieved is confirmed, so that all the car is in a relieved state at the same time; (2) Quick pipe removing, namely, uniformly and quickly removing the air pipe connection; (3) And pulling the anti-jump hook, namely rapidly pulling the anti-jump hook bolt and preventing the car coupler from jumping up accidentally. 3. Accurate alignment command method for shunting personnel (1) Station, shunting personnel are positioned at a preset observation point; (2) Pressing down the wireless command device to start communication; (3) Sending an operation instruction to a locomotive driver; (4) And the method is used for commanding the locomotive to start and finish accurate alignment. 4. Locomotive driver cooperative operation flow (1) Confirming an operation signal; (2) Accelerating the lifting handle to start the locomotive; (3) The speed is reduced steadily to approach the towed vehicle; (4) The car coupler is tightly supported by the trailer by light acceleration; (5) Controlling the speed of the vehicle to enable the train to run at a constant speed; (6) Accurate parking is achieved according to the on-site signboard. In the technical scheme, more specific scheme is that the air exhaust pull rod is used for exhausting air for 5 seconds per car. By adopting the technical scheme, compared with the prior art, the invention has the following beneficial effects: 1. the operation time is greatly shortened, for example, the exhaust time of 22 train carriages is reduced from 20 minutes to 10 minutes, and the efficiency is improved by 50 percent; 2. the comprehensive benefit is obvious, the number of turns over 3 groups of carriages per shift can be saved by 30 minutes, the daily time can be saved by 90 minutes, and a great amount of operation time can be saved by annual accumulation; 3.
