Description

Technical Field

[0001] The utility model belongs to the field of preheating devices, in particular to a device used for preheating a coke oven door. Background Art

[0002] In order to avoid a sharp increase in temperature caused by direct installation and use of a cold furnace door, the furnace door is usually fixed on a preheating rack, and then part of the heat energy released by the side combustion chamber is used to preheat the repaired coke oven door. This not only reduces the investment in equipment and energy consumption, but also prevents a sharp increase in temperature caused by direct installation and use of a cold furnace door, and avoids the lining bricks in the furnace door from being subjected to the impact of rapid cooling and heating, thereby extending the service life of the furnace door.

[0003] After searching, it was found that the patent document with application number: 202111386794.6 uses bolts to connect the protective plate and the connecting plate. Therefore, when connecting the protective plate and the connecting plate, it is necessary to first align the connecting holes on the protective plate and the connecting plate, and then use tools such as wrenches to install and tighten multiple bolts, which is relatively inconvenient.

[0004] To this end, we provide a device for preheating a coke oven door to solve the above-mentioned problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0028] See also Figure 1-4 The utility model is a device for preheating a coke oven door, comprising a protection plate 1 and a connecting plate 2. A positioning block 3 is fixedly connected to the front surface of the protection plate 1, and a positioning groove 5 is provided on the positioning block 3. An inserting block 4 is fixedly connected to the left surface of the connecting plate 2, and the outer surface of the inserting block 4 is movably connected to the positioning groove 5.

[0029] The fixed structure 15 includes a connecting block 6, a connecting rod 7, a flip block 8, a screw rod 9, a movable block 10 and a docking block 11. The rear surface of the connecting block 6 is fixedly connected to the protective plate 1, the side surface of the connecting rod 7 is fixedly connected to the connecting block 6, the inner surface of the flip block 8 is rotatably connected to the connecting rod 7, the right surface of the flip block 8 is fixedly connected to the screw rod 9, the inner surface of the movable block 10 is threadedly connected to the screw rod 9, the right surface of the docking block 11 is fixedly connected to the connecting plate 2, and the outer surface of the screw rod 9 is movably connected to the docking block 11.

[0030] Specifically, one end of the screw rod 9 away from the flip block 8 is fixedly connected with a first anti-slip block 12, the left surface of the movable block 10 is in contact with the docking block 11, and one end of the connecting rod 7 away from the connecting block 6 is fixedly connected with a second anti-slip block 13, the side surface of the second anti-slip block 13 is in contact with the flip block 8, and a movable groove 14 is provided on the docking block 11, and the outer surface of the screw rod 9 is movably connected with the movable groove 14. Through the setting of the first anti-slip block 12, the movable block 10 is prevented from detaching from the screw rod 9, and at the same time, under the action of the second anti-slip block 13, the flip block 8 is prevented from detaching from the connecting rod 7. Specific embodiment 2

[0032] See also Figure 1-4 On the basis of the specific embodiment 1, the connecting rod 7 passes through the flip block 8, the side surface of the connecting block 6 contacts the flip block 8, the rear surface of the connecting plate 2 contacts the protection plate 1, the number of the positioning blocks 3 is two and they are distributed up and down, the number of the plug blocks 4 is two and they are distributed up and down, and the number of the fixing structures 15 is two and they are distributed up and down.

[0033] Specifically, by setting the positioning block 3 and the plug block 4, the preliminary connection between the protection plate 1 and the connecting plate 2 can be achieved, and by setting the fixing structure 15, it is easy to fix the protection plate 1 and the connecting plate 2 between them.

[0034] The working principle of the utility model is as follows: by rotating the movable block 10, the movable block 10 can move horizontally on the screw rod 9. When the movable block 10 is no longer in contact with the docking block 11, the fixation of the screw rod 9 is released. When the movable block 10 after movement is not affected by the docking block 11 to flip, the screw rod 9 is flipped, so that the flipped screw rod 9 drives the flipping block 8, the movable block 10 and the first anti-detachment block 12 to flip with the connecting rod 7 on the connecting block 6 as the central axis. At the same time, under the action of the second anti-detachment block 13, the flipping block 8 can be restricted to prevent the flipping block 8 from detaching from the connecting rod 7. When the screw rod 9 after flipping is detached from the movable groove 14, the connection between the protection plate 1 and the connecting plate 2 is released, and the protection plate 1 and the connecting plate 2 can be connected. When the protection plate 1 and the connecting plate 2 are separated, the initial connection between the protection plate 1 and the connecting plate 2 can be achieved by inserting the plug block 4 on the connecting plate 2 into the positioning groove 5 on the positioning block 3, so that the screw rod 9 can correspond to the movable groove 14, and then the screw rod 9 is flipped in the reverse direction, so that the flipped screw rod 9 drives the flip block 8, the movable block 10 and the first anti-slip block 12 to flip. When the flipped screw rod 9 is inserted into the movable groove 14, the movable block 10 is rotated in the reverse direction to move the movable block 10 horizontally on the screw rod 9. When the moved movable block 10 contacts the docking block 11, the movable block 10 can no longer move, thereby realizing the fixation of the screw rod 9, and completing the connection and fixation between the protection plate 1 and the connecting plate 2 at the same time, which is convenient and quick.
