Description

Technical Field

[0001] This invention relates to the field of coking engineering technology, and in particular to an auxiliary device and method for installing large furnace door lining bricks. Background Technology

[0002] Currently, in the coking industry, the furnace door lining bricks used domestically are mostly small cordierite bricks. These bricks are small in size, making them convenient for workers to install. However, these bricks have significant drawbacks: they are time-consuming and labor-intensive to install, and if damaged, they require a long time to replace and repair, affecting the normal production and operation of coking plants.

[0003] In light of this, a new type of furnace door lining brick has emerged in recent years. This type of furnace door lining brick is a large refractory precast block, made of high-alumina cordierite material and glazed on the surface. Designed in sections according to the furnace door height, furnace doors commonly used in the industry are generally divided into 5 to 7 sections, with 4 to 6 sections at the top, each section being 1.3 meters high. The bottom section, which needs to be combined with the brick support groove, uses a lining brick with a height of 0.6 meters. Each lining brick section is designed with fastener connection holes, using stainless steel fasteners to arrange the lining bricks in a row, tightly connecting and fixing them to the bolt holes inside the furnace door frame. This new type of furnace door lining brick is a large refractory precast block (castable block), with a single lining brick weighing over 500 kg. In actual installation, it cannot be done manually and requires tools. Therefore, traditional construction methods are no longer suitable for the industry's development, and finding a simple, fast, and low-cost installation method for large furnace door lining bricks is urgently needed.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1 to 4 As shown, the present invention proposes an auxiliary device for installing large furnace door lining bricks, comprising an installation platform and a moving mechanism. At least two installation platforms are provided, each with a bench-like structure, consisting of columns 1, beams 2, and cross braces 3. Four columns 1 are vertically arranged. A horizontal beam 2 connects the tops of adjacent columns 1, serving to connect the columns 1 into a whole and support the furnace door 9. Horizontal cross braces 3 connect adjacent columns 1 to enhance the stability of the installation platform.

[0020] The moving mechanism consists of an axle 4, wheels 5, a bracket 6, a main beam 7, and hooks 8. Wheels 5 are mounted on both ends of the axle 4. Two brackets 6 are connected to the axle 4 at a certain angle. Each bracket 6 consists of two support rods, one end of which is connected to one end of the main shaft, and the other ends of the two support rods are connected together and then to the main beam 7. The ratio of the power arm to the resistance arm of the main beam 7 is greater than or equal to 4:1, and hooks 8 are connected to the ends of the resistance arms of the main beam 7.

[0021] The following describes the auxiliary device for installing large furnace door lining bricks with specific embodiments: Ordinary welded steel pipes with a specification of Ф48×3.0 are cut to a certain length to serve as the uprights 1 and crossbeams 2 of the installation platform. In this embodiment, four uprights 1 are provided. Round steel with a diameter of 20mm is cut to a certain length to make the cross braces 3 of the installation platform. The uprights 1, crossbeams 2, and cross braces 3 are fixedly connected together by welding to form the installation platform. In this embodiment, two installation platforms are provided.

[0022] The moving mechanism can be modified from a trolley, specifically by adding a bracket 6 and a main beam 7 to the axle 4. The specific construction method is as follows: the trolley's wheels 5 and axle 4 serve as the moving chassis. The bracket 6 is installed on the axle 4, and the main beam 7 is installed on the bracket 6. Both the bracket 6 and the main beam 7 are made of ordinary welded steel pipe with a specification of Ф48×3.0, and are installed and fixed together by welding. Based on the lever principle, the front end of the main beam 7 is shorter than the rear end, and the ratio of the effort arm to the resistance arm is not less than 4:1. This greatly saves manpower and allows for easy operation by two people. A hook 8 is welded to the front end of the main beam 7 for hanging the furnace door lining bricks, and the rear end is an operating lever for manually operating the moving mechanism.

[0023] The installation method for large furnace door lining bricks shall be carried out according to the following steps: S1. Place the installation platform near the furnace door lining brick stacking area and secure it firmly. The placement of the installation platform should follow the principle of proximity, while also considering that the operating area is flat and free of debris, the furnace door lining brick transfer channel is clean and tidy, and the site is hardened. Then place the furnace door 9 on the installation platform, with the side of the furnace door 9 that is in contact with the furnace door lining brick facing upwards.

[0024] S2. According to the design requirements, attach refractory asbestos rope to the furnace door 9, determine the installation sequence of the furnace door lining bricks, and do the preparatory work before the installation of the furnace door lining bricks.

[0025] S3. According to the installation sequence of the furnace door lining bricks, the moving mechanism is used to transfer the furnace door lining bricks to be installed to the installation platform, and the position of the furnace door lining bricks is adjusted so that the bolt holes on the furnace door lining bricks are aligned with the mounting holes on the furnace door 9. The specific steps are as follows: According to the installation sequence of the furnace door lining bricks, the moving mechanism, in conjunction with the furnace door lining brick hoisting clamp device, hangs the furnace door lining bricks to be installed on the hook 8. Press down on the power arm of the main beam 7 to lift the furnace door lining bricks hanging on the hook 8 upwards. Push the moving mechanism to slowly move the furnace door lining bricks to above the installation position of the furnace door lining bricks on the furnace door 9, and slowly lower the furnace door lining bricks, constantly adjusting the alignment during the descent, and using a pry bar as needed to assist in aligning the bolt holes on the furnace door lining bricks with the mounting holes on the furnace door 9.

[0026] S4. Use fasteners to pass through the bolt holes and mounting holes respectively. The fasteners can be bolts. Tighten the nuts on the bolts to fix the furnace door lining bricks to the furnace door 9.

[0027] S5. Adhere refractory asbestos rope to the vertical surface of the furnace door lining bricks.

[0028] S6. Repeat S3 to S5 to install the next furnace door lining brick.

[0029] The embodiments of this invention are intended to cover all such substitutions, modifications, and variations falling within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
