Description

Technical Field

[0001] This utility model relates to the field of coke oven door technology, specifically a rigidly reinforced 7-meter coke oven door. Background Technology

[0002] Coke oven doors are auxiliary equipment used to open and close the openings at both ends of the coke oven's carbonization chamber. They play a crucial role in coke oven production, providing a sealing function: when the door is closed, the carbonization chamber is isolated from the atmosphere, maintaining a dry distillation state; when opened, the pusher rod allows coke to be pushed out. Structural classification: Coke oven doors are divided into machine-side doors and coke-side doors. The machine-side door has a small door at the upper end for the leveling rod to extend into the carbonization chamber to level the coal.

[0003] Most existing furnace doors have several internally welded support beams to make them more stable. However, some of these support beams are rectangular in shape. When the furnace door expands due to heat, the rectangular support beams do not absorb radial expansion well, which can lead to stress concentration and weld breakage, thus reducing the stability of the furnace door.

[0004] Meanwhile, some of the existing support beams are directly welded to the inside of the furnace door, without any interlocking relationship between them and the furnace door. They are only connected by welding, which leads to the support beams breaking under the weight of the furnace door and the tension of the opening and closing mechanism. Furthermore, when the furnace door is hoisted by the hoisting mechanism, there is no structure to limit the steel wire rope, which makes the steel wire rope prone to movement during hoisting, affecting the safety of hoisting the furnace door. Utility Model Content

[0005] The purpose of this invention is to provide a rigidly reinforced 7-meter coke oven door to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rigidly reinforced 7-meter coke oven door, including a door mechanism and a locking groove formed on its surface, and further comprising:

[0007] A support beam, which is installed inside the furnace door mechanism, can absorb the radial thermal expansion of the furnace door through its shape. Both sides of the surface of the support beam are fixedly connected to a fixing plate that works with the locking groove to increase the connection strength. Both sides of the surface of the support beam are fixedly connected to a support plate that increases the stability of the support beam through diagonal support.

[0008] A connecting groove is formed on the surface of the supporting beam. On both sides of the top of the connecting groove, a positioning groove is formed by the shape of the groove to limit the steel wire rope. On both sides of the surface of the supporting beam, a locking mechanism is installed to facilitate adjustment of the position and further limit the steel wire rope.

[0009] Preferably, the positioning mechanism includes a blocking frame fixedly disposed on one side of the supporting beam, the inner cavity of the blocking frame is provided with bolts, and the surface of the supporting beam is provided with threaded holes.

[0010] Preferably, the cross-sectional shape of the blocking frame is an L-shaped structure, and the raised side of its surface faces the outside of the supporting beam.

[0011] Preferably, the fixing plate and the supporting beam are integrally formed, and the top of the supporting beam is an arc-shaped structure.

[0012] Preferably, one side of the support plate has an inclined structure design with an inclination angle of 45 degrees.

[0013] Preferably, the positioning groove is symmetrically designed with respect to the center point of the supporting beam, the inner cavity of the positioning groove is an arc-shaped structure, and its edges are provided with rounded chamfers.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention effectively absorbs the radial thermal expansion of the furnace door through the shape of the supporting beam, thereby reducing the possibility of stress concentration and weld breakage in the furnace door. It effectively improves the stability of the furnace door connection. Furthermore, the cooperation between the locking groove and the fixing plate increases the stability of the supporting beam. With the cooperation between the positioning groove and the locking mechanism, the steel wire rope can be limited during the hoisting process, preventing it from moving arbitrarily and affecting the safety of hoisting. This solves the problem of poor stability and low safety of existing furnace doors during use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, a rigidly reinforced 7-meter coke oven door includes a door mechanism 1, which isolates the carbonization chamber from the atmosphere, thus preserving the dry distillation state. The surface of the door mechanism 1 has several locking grooves 2, arranged symmetrically in pairs. Inside the door mechanism 1 is a supporting beam 3, with fixing plates 4 fixedly connected to both sides of the beam. The fixing plates 4 and the supporting beam 3 are integrally formed, enhancing the connection between them. The top of the supporting beam 3 has an arc-shaped structure, which supports the interior of the door mechanism 1, buffering the stress on the door mechanism 1 during use and making it more stable. The shape of the beam further contributes to the overall design. It can greatly absorb radial expansion, thereby reducing local stress concentration and effectively reducing the possibility of cracking at the end weld due to linear expansion of the furnace door. The inner wall of the locking groove 2 and the surface of the fixing plate 4 are connected to each other by welding. Under this effect, the welding area between the locking groove 2 and the fixing plate 4 can be increased compared with the existing ordinary connection. Furthermore, by embedding the fixing plate 4 into the interior of the locking groove 2, the connection effect between the furnace door mechanism 1 and the supporting beam 3 can be further enhanced, effectively reducing the possibility of weld seam detachment between the supporting beam 3 and the furnace door mechanism 1. This effectively improves the connection effect between the furnace door mechanism 1 and the supporting beam 3, enhances the stability of the furnace door, and also increases the furnace door's ability to withstand its own weight and the tension of the opening and closing mechanism during use, thus effectively improving the stability of the furnace door.

[0023] Support plates 5 are fixedly connected to both sides of the surface of the supporting beam 3. The other side of the support plate 5 is used in conjunction with the furnace door mechanism 1. Under this action, the furnace door mechanism 1 and the supporting beam 3 can be supported, thereby making the supporting beam 3 more stable. One side of the support plate 5 has an inclined structure design with an inclination angle of 45 degrees. Under this action, the connection effect between the supporting beam 3 and the furnace door mechanism 1 can be further improved by the shape of the support plate 5. Moreover, the support angle is the optimal force angle, which improves the normal effect of the supporting beam 3. The surface of the supporting beam 3 is provided with a connecting groove 6. The connecting groove 6 is used to provide an effective force point when hoisting and opening and closing the furnace door, thereby making the furnace door easier to move. Positioning grooves 7 are provided on both sides of the top of the inner cavity of the connecting groove 6. The positioning grooves 7 are symmetrically designed with respect to the center point of the supporting beam 3. The inner cavity of the positioning groove 7 is arc-shaped. The furnace door features a unique structural design with rounded chamfers at its edges. This design allows the wire rope to be secured within the positioning groove 7 via the connecting groove 6 during hoisting, thus positioning the rope and preventing it from moving freely due to low friction with the inner wall of the connecting groove 6. This effectively improves the stability of the furnace door during hoisting. Furthermore, the rounded corners within the positioning groove 7 reduce the shear force exerted on the wire rope by the inner wall of the positioning groove 7, thereby reducing the risk of breakage and enhancing the applicability of the positioning groove 7. Two locking mechanisms 8 are installed on both sides of the support beam 3 surface, further limiting the wire rope's movement within the positioning groove 7 and further improving its stability during furnace door hoisting.

[0024] The positioning mechanism 8 includes a blocking frame 81 fixedly mounted on one side of the supporting beam 3. A bolt 82 is installed inside the blocking frame 81, and a threaded hole 83 is formed on the surface of the supporting beam 3. The inner wall of the threaded hole 83 is threadedly connected to the surface of the bolt 82. Under this action, the blocking frame 81 can be installed through the cooperation of the bolt 82 and the threaded hole 83. The blocking frame 81 has an L-shaped cross-section, with its convex side facing the outside of the supporting beam 3. Under this action, the shape and position further obstruct the wire rope. This further limits the movement of the wire rope, preventing it from moving arbitrarily and affecting the safety of the furnace door during hoisting, effectively improving the applicability of the furnace door. Furthermore, with the cooperation of bolt 82 and threaded hole 83, the blocking frame 81 can be disassembled, making it easy to remove the blocking frame 81 from the surface of the support beam 3 that does not require hoisting. This not only allows the blocking frame 81 to be easily installed on the surface of the support beam 3 in a suitable position, but also prevents the position of the blocking frame 81 from affecting the movement of the furnace door by the subsequent opening and closing mechanism, effectively improving the applicability of the furnace door.

[0025] It is worth noting that the technical features such as the furnace door mechanism 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, control method and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0026] Working principle: First, the cooperation between the locking groove 2 and the fixing plate 4 increases the welding area, making the supporting beam 3 more stable during use. When the furnace door expands due to high heat, the shape of the supporting beam 3 effectively absorbs the radial expansion, reducing stress concentration and lowering the risk of weld cracking. When the furnace door needs to be hoisted, the worker passes the wire rope through the connecting groove 6 and then locks it in the positioning groove 7. The positioning groove 7 limits the wire rope, preventing it from moving freely and affecting the safety of hoisting the furnace door. With the cooperation of the blocking frame 81, the wire rope can be further limited, further improving its stability and effectively enhancing the safety of the furnace door during hoisting.
