Abstract

The embodiment of the invention provides a water quenching car and a control method thereof, and relates to the technical field of coking. The water quenching car comprises a carriage and the abnormal opening prevention device, wherein the carriage comprises a carriage door and a carriage wall which are connected with each other; the abnormal opening prevention device comprises a connecting plate, an electric-hydraulic push rod and a locking frame, the connecting plate is connected to the compartment door, a lock hole is formed in the connecting plate, the locking frame is connected to the compartment wall, and a telescopic rod of the electric-hydraulic push rod is used for penetrating through the lock hole and being inserted into the locking frame so as to prevent the compartment door from being opened abnormally. Thus, an abnormal opening prevention device is additionally arranged, after pressure is insufficient due to pressure relief of a transmission pipeline and under the condition that the compartment door is extremely easy to open under the impact of high-pressure water, the abnormal opening prevention device is started, a telescopic rod of an electric-hydraulic push rod penetrates through a lock hole and is inserted into a locking frame, so that the compartment door is prevented from being opened abnormally, and the compartment door does not act in the water quenching tower; and the carriage door is always closed.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a water quenching vehicle and a control method thereof. Background technique [0002] The compartment door of the existing coke oven water quenching car adopts a compressed air device, which sends the compressed air to the opening and closing cylinder installed on the structural beam through the pipeline, and then the opening and closing cylinder drives the crank linkage mechanism to open the compartment door or off. The compressed air pipeline is highly corroded, and it is very easy to leak air and release pressure. In addition, the water quenching car will bear the impact of high-pressure water in the quenching tower, and the crank linkage mechanism is very easy to move, and then the door of the car is opened, which leads to all the coke. It falls on the track inside the tower, affecting production. [0003] Therefore, it is a technical problem to be solved urgently how to loc...
