Abstract
Description
Technical Field
[0001] The utility model relates to an opening and closing device for an upper furnace door of a coke oven, belonging to the technical field of coke ovens. Background Art
[0002] Currently, the existing opening and closing lifting rings of the upper furnace door all adopt a fixed structure. Due to the high height of the lifting rings, when the lifting rings are not in use, they affect the normal operation of other equipment. Content of the Utility Model
[0003] In order to solve the technical problems existing in the prior art, the utility model provides an opening and closing device for an upper furnace door of a coke oven, which has a simple structure, reasonable design, adopts a movable structure, and can be laid down and erected as needed.
[0004] To achieve the above object, the technical solution adopted by the utility model is an opening and closing device for an upper furnace door of a coke oven, including lifting rings installed on both sides of the upper furnace door. The lifting rings include a fixed seat and an upper lifting ring. The fixed seat is installed on the upper furnace door of the coke oven. First hinge ears are respectively installed on both sides of the fixed seat. Second hinge ears are respectively installed on both sides of the bottom of the upper lifting ring. One of the second hinge ears is installed on the first hinge ear through a pin shaft. The upper lifting ring is used to rotate around the fixed seat through the pin shaft. The other second hinge ear and the first hinge ear are connected through a movable pin. A limiting plate is also installed on the fixed seat. When the upper lifting ring rotates 90° around the fixed seat, the upper lifting ring is supported on the limiting plate.
[0005] Preferably, a positioning plate is also installed on the fixed seat. The positioning plate is located on one side of the upper lifting ring. A positioning hole is provided on the positioning plate. When the upper lifting ring rotates 90° around the fixed seat, the second hinge ear is installed in the positioning hole of the positioning plate through a movable pin.
[0006] Preferably, a buffer pad is installed on the limiting plate.
[0007] Compared with the prior art, the utility model has the following technical effects: The utility model has a simple structure, reasonable design, the lifting rings adopt a movable structure, can be laid down and erected, the operation is simple, and it is convenient to use. When the upper furnace door is operating, the lifting rings can be laid down without affecting the operation of other equipment. Description of the Drawings
[0008] Figure 1 It is a structural schematic diagram of the utility model.
[0009] Figure 2 It is a structural schematic diagram of the lifting ring in the vertical state of the utility model. Detailed Implementation Modes
[0010] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0011] As Figure 1 and Figure 2 shown, an opening and closing device for the upper furnace door of a coke oven includes lifting rings 1 installed on both sides of the upper furnace door. The lifting rings 1 include fixed seats 2 and upper lifting rings 3. The fixed seats 2 are installed on the upper furnace door of the coke oven. First hinged ears 4 are installed on both sides of the fixed seat 2. Second hinged ears 5 are installed on both sides of the bottom of the upper lifting ring 3. One of the second hinged ears 5 is installed on the first hinged ear 4 through a pin shaft 6. The upper lifting ring 3 is used to rotate around the fixed seat 2 through the pin shaft. The other second hinged ear 5 and the first hinged ear 6 are connected by a movable pin. A limiting plate 7 is also installed on the fixed seat 2. When the upper lifting ring 3 rotates 90° around the fixed seat, the upper lifting ring 3 is supported on the limiting plate 7.
[0012] In the present utility model, the lifting rings adopt a combined structure. The upper lifting ring 3 is hinged to the fixed seat 2 and can rotate around the fixed seat 2. When the lifting rings are needed, the upper lifting ring 3 is vertical on the fixed seat 2, and at the same time, the upper lifting ring 3 and the fixed seat 2 are connected by a movable pin. When not in use, the upper lifting ring 3 can be laid flat and supported on the limiting plate 7, which is convenient to operate and does not affect the operation of other equipment. A buffer pad is installed on the limiting plate 7, which can reduce the noise generated by the collision between the upper lifting ring 3 and the fixed seat 2.
[0013] Among them, a positioning plate 8 is also installed on the fixed seat 2. The positioning plate 8 is located on one side of the upper lifting ring. A positioning hole 9 is provided on the positioning plate 8. When the upper lifting ring 3 rotates 90° around the fixed seat, the second hinged ear 5 is installed in the positioning hole 9 of the positioning plate through a movable pin. The positioning plate 8 can fix the upper lifting ring 3. When the upper lifting ring 3 is laid down, the upper lifting ring 3 is connected to the positioning plate 8 through a movable pin to ensure reliable positioning of the upper lifting ring 3.
[0014] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present utility model shall be included within the scope of the present utility model.
