Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of accessories for coke guide cars, in particular to a high-temperature-proof device for a door taking hydraulic cylinder of a coke guide car. BACKGROUND

[0002] When the coke guide car opens the door of the coke oven, the door taking machine rotates to make the door of the coke oven horizontally loose, at the same time, the operator needs to pull the horizontal card to make the horizontal iron separate from the door frame groove, thus completing the door opening operation. This operation needs to be repeated every time the door is opened, thus there is a great safety hazard. The door taking machine of the coke guide car takes the door of the coke oven, and the door taking machine has one up and down swing type door bolt oil cylinder to press the door bolt nut of the coke oven, so that the horizontal iron of the door is loosened and retracted. The door bolt oil cylinder presses the door bolt nut several hundred times a day. Since the head of the door bolt oil cylinder and the door bolt nut are not completely aligned every time, the force is uneven, the protective pad of the head of the door bolt oil cylinder often falls off, the door bolt stroke is not in place, and the door cannot be taken, which affects production.

[0003] After searching, a coke oven coke guide car door taking mechanism (publication number: CN205024148U) is disclosed in the prior art. The document records that "the frame is a right side opening frame structure, the oil cylinder frame is also a right side opening frame structure, the frame and the oil cylinder frame are connected by the sliding rods on the upper and lower end faces of the oil cylinder frame; the drive oil cylinder is fixed on the left side wall outside the frame; the door pressing oil cylinder is fixed on the inner side wall of the oil cylinder frame in an upper and lower structure; the door lifting oil cylinder is fixed on the inner side wall of the frame and connected with the upper door pressing oil cylinder through the piston rod." The mechanism drives the door opening through the driving of the drive oil cylinder, the lifting of the door lifting oil cylinder and the pressing of the door pressing oil cylinder, and fixes the door through the positioning of the positioning mechanism and the detachable fixed connection mechanism. The mechanism effectively solves the problems of uneven force caused by misalignment of the head of the door bolt oil cylinder and the door bolt nut, frequent falling off of the protective pad of the head of the door bolt oil cylinder and out-of-position of the door bolt stroke, and improves the service life of the door taking mechanism of the coke guide car. However, the oil cylinder parts in the mechanism are close to the door, and the high temperature radiation in the door can easily increase the temperature around the various oil cylinder parts arranged in the oil cylinder frame, which can cause abnormal error of the sensor data on the oil cylinder parts, thus affecting the normal work of the coke guide car.

During the operation of the coke guide car, the switch of the external high-pressure water source connected to the liquid injection pipe is started, and the cooling liquid in the high-pressure water source can flow into the inside of the bus bar 13 on one side of the oil cylinder box 2 through the liquid injection pipe.
