[0002] During the coal charging process of the top-loading coke oven in the coking plant, a flat coal rod is required for leveling the coal. A small furnace door is designed at the upper part of the furnace door. When charging coal, the small furnace door needs to be opened, and the flat coal rod performs the coal leveling operation through the opening of the small furnace door. After the coal leveling is completed, the small furnace door is closed again. The function of the side-opening small furnace door opening and closing mechanism is to open or close the small furnace door by the manipulator clamping the rocker arm of the small furnace door and rotating it by 90°, realizing automatic operation and avoiding dangers such as burns caused by manual opening and closing of the small furnace door.

[0003] At present, the opening and closing mechanism of the side-opening small furnace door of the coke oven in the coking plant is driven by a fixed oil cylinder. The manipulator is driven by the oil cylinder to drive the connecting pin to slide in the slideway to complete the action. The device has a complex structure, large frictional resistance, is easy to wear and cause inaccurate actions. Coupled with the harsh use environment, it has a high failure rate, difficult maintenance, large consumption of spare parts, and affects the coal charging time. Therefore, there is an urgent need to improve the existing small furnace door opening and closing mechanism. Summary of the Utility Model

[0017] Figure 1 、 2It is shown that the base 2 is a rectangular plate, and an oil cylinder base plate 3 is fixed to the rear end of the base 2. The oil cylinder base plate 3 extends outside the base 2, and the oil cylinder 4 is installed on the oil cylinder base plate 3 outside the base 2. Such a design can make the oil cylinder rod 5 at the front end of the oil cylinder 4 not in a straight line with the manipulator 1 below the base 2. The dislocation of the oil cylinder 4 and the manipulator 1 can pull the manipulator 1 to rotate when the oil cylinder rod 5 moves back and forth.

[0018] Figure 1 、 2 It is shown that there is an oil cylinder tail seat 6 at the rear end of the oil cylinder 4, which is connected to the oil cylinder base plate 3 through a rotating pin shaft 7. Changing the existing fixed connection of the oil cylinder 4 to a rotatable connection can cooperate with the rotation of the oil cylinder rod 5 and the arc-shaped rotating plate 8.

[0019] Figure 1 、 2 It is shown that the front end of the oil cylinder rod 5 of the oil cylinder 4 is connected to the rear end of the arc-shaped rotating plate 8 through a connector 10. The front end of the oil cylinder rod 5 of the oil cylinder 4 has a thread, and the rear end of the connector 10 is threadedly connected to the front end of the oil cylinder rod 5 and is fixed by a locking nut 11.

There are opposite pin holes on both side surfaces of the U-shaped groove 12, and a connector pin shaft 13 connects the front end of the connector 10 and the front end of the arc-shaped rotating plate 8 through the pin holes.

[0021] Figure 1 、 2 It is shown that the manipulator 1 is located below the front end of the base 2, the rear end of the arc-shaped rotating plate 8 is opposite to the manipulator 1 above the base 2, the upper end of the manipulator connecting pin shaft 9 is connected to the rear end of the arc-shaped rotating plate 8, the manipulator connecting pin shaft 9 vertically passes through the plate surface of the base 2, and the lower end of the manipulator connecting pin shaft 9 is connected to the manipulator 1.

It is changed to connect the arc-shaped rotating plate 8 with the connecting head 10, and through the pulling action of the cylinder rod 4 of the oil cylinder 4 on the arc-shaped rotating plate 8, the 90° rotation of the manipulator 1 connected to the manipulator connecting pin shaft 9 is completed; the fixed oil cylinder 4 of the existing manipulator driving mechanism is also changed to a swingable oil cylinder, and the connecting rod 16 at the front of the cylinder rod 5 is removed by rotation and changed to the rotation of the cylinder tailstock 6. These improvements have simplified the opening and closing driving mechanism of the small furnace door of the coke oven.

When the manipulator 1 rotates 90°, the small furnace door opens; after the coal leveling rod extends into the small furnace door to complete coal leveling and then withdraws, the cylinder rod 5 moves forward, drives the manipulator 1 to rotate back 90°, and toggles the small furnace door rocker arm to close the small furnace door.
