[0002] The coke oven door is the core component of the coke oven carbonization chamber sealing system. During installation, it must be accurately aligned with the sealing surface of the oven body, which directly affects the environmental emission compliance rate and thermal efficiency of the coke oven.

[0003] Currently, the dismantling and installation of coke oven doors mainly relies on specialized door replacement equipment or coke oven cranes. However, such equipment is expensive to purchase, complex to maintain, and has a limited operating range, making it difficult for small and medium-sized coking enterprises to equip themselves with it. Some enterprises use wire ropes with hooks for hoisting, but the swing amplitude during hoisting is large and difficult to control, which can easily lead to hard collisions between the door and the oven opening, and it is also difficult to align the door with the oven opening for installation. Summary of the Invention

[0004] Based on the above-mentioned technical problems, the purpose of this invention is to provide a coke oven door installation component and installation method adapted to excavators, which can be directly adapted to excavators on the construction site without the need for additional special equipment. It can be directly used to replace the bucket, reducing investment costs, and can stably install the oven door, avoiding oven door swing, thereby reducing hard collisions between the oven door and the oven opening during installation.

[0005] The specific technical solution is as follows: A coke oven door mounting component adapted for excavators includes: a main frame, two excavator connecting seats, two door contact plates, two reinforcing ribs, two protective contact parts, mounting holes, steel pipes, and bolt slots. The two excavator connecting seats are fixed to the main frame and hinged to the excavator boom via pins. The two door contact plates are welded to both sides of the main frame and are located on the side facing the coke oven door. The two reinforcing ribs are welded to both the main frame and the door contact plates. The two protective contact parts are connected to the sides of the two door contact plates closest to the coke oven door. Mounting holes are provided on the two door contact plates, through which the steel pipe passes. One end of the steel pipe has a bolt slot for engaging the bolt of the coke oven door.

[0006] In addition, the coke oven door mounting component adapted to an excavator in the above-mentioned technical solution provided by the present invention may also have the following additional technical features: In the above technical solution, the protective contact part is a rubber pad with a thickness of 10mm.

[0007] In the above technical solution, the thickness of the main frame of the component is 18-20mm, the thickness of the furnace door contact plate is 20mm, and the thickness of the reinforcing rib is 16mm.

[0008] In the above technical solution, the bolt slot is a U-shaped groove.

[0009] In the above technical solution, the other end of the steel pipe is provided with an external thread, and a fixing nut is threadedly connected to the external thread.

[0010] An installation method for a coke oven door mounting component adapted to an excavator includes the following steps: S1: Remove the excavator bucket, connect the excavator connecting seat of the component to the hinge seat of the excavator boom through the pin, tighten the pin nut to complete the fixing of the component to the excavator; S2: Select a steel pipe of the corresponding length according to the bolt spacing of the coke oven door to be installed, pass the steel pipe through the installation hole, and fix the position of the steel pipe with the fixing nut; S3: Operate the excavator to move the components so that the door bolt of the furnace door is engaged in the door bolt slot of the steel pipe, so that the door bolt and the door bolt slot are tightly fitted. S4: Operate the excavator to adjust the posture of the component, lift the furnace door, and transport it above the coke oven opening; adjust the movement of the excavator's boom to precisely align the sealing surface of the furnace door with the furnace opening, and push the furnace door to the sealing position; S5: After confirming that the furnace door is installed in place, operate the excavator to move the component away from the furnace door, so that the door bolt slot is disengaged from the furnace door bolt, and the installation work is completed.

[0011] The present invention provides a coke oven door installation component and installation method adapted for excavators, which, compared with the prior art, has the following advantages: 1.

Detailed Implementation

[0015] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described, but the present invention is not limited to these embodiments.

[0016] A coke oven door mounting component adapted for excavators, such as Figure 1-5 As shown, the system includes: a main frame 10, two excavator connecting seats 11, two furnace door contact plates 12, two reinforcing ribs 13, two protective contact parts 14, mounting holes 15, steel pipes 16, and bolt slots 17. The two excavator connecting seats 11 are fixed to the main frame 10 and are hinged to the excavator arm via pins. The two furnace door contact plates 12 are welded to both sides of the main frame 10 and are located on the side facing the coke oven door 19.

Mounting holes 15 are provided on the two furnace door contact plates 12, through which the steel pipe 16 passes. One end of the steel pipe 16 has a bolt slot 17 for engaging the bolt 20 of the coke oven door 19.

[0017] With the above structure, this component is hinged to the excavator boom pin via the excavator connecting seat 11, and can be directly used to replace the bucket. There is no need to purchase a special furnace door 19 to replace the equipment or a special coke oven crane. By using it in conjunction with excavators commonly found on construction sites, the investment cost of the equipment is reduced.

[0018] The excavator drives the main frame 10 of the component to move laterally, so that the bolt 20 of the furnace door 19 is inserted into the bolt slot 17 of the steel pipe 16, realizing the quick connection between the furnace door 19 and the main frame 10 of the component. Then, the excavator drives the furnace door 19 for installation, realizing precise control of the position of the furnace door 19 and preventing the furnace door 19 from swinging during hoisting. After the furnace door 19 is installed, the excavator controls the main frame 10 of the component to move laterally in the opposite direction, so that the bolt slot 17 of the steel pipe 16 is disengaged from the bolt 20 of the furnace door 19, quickly completing the unhooking, improving work efficiency, and supporting reuse.

[0019] By symmetrically arranging furnace door contact plates 12 and protective contact parts 14 on both sides of the main frame, the protective contact parts 14 can prevent the furnace door contact plates 12 from directly scraping the surface of the furnace door 19 during hoisting.

[0020] Specifically, the width of the furnace door contact plate 12 is ≥300mm.
