Description

Technical Field

[0001] The present application relates to the technical field of blast furnace bottom carbon brick masonry construction, and in particular to a blast furnace lining ring carbon brick construction tool. Background Art

[0002] The method of laying carbon bricks for blast furnaces is to use the electric hoist of the radiation suspension beam of the construction protection shed to lift, raise and lower the carbon bricks, and put them in place. Due to the influence of the cooling wall of the blast furnace, the middle sleeve of the tuyere, and the construction platform in the furnace, the carbon bricks around the bottom of the blast furnace and the annular carbon bricks in the furnace cannot be lifted and lowered vertically by the electric hoist. Construction units often use multiple people to hold the carbon bricks together, and at the same time, with the cooperation of the operator, they are forcibly pushed, tilted and lifted to the surrounding positions. According to the traditional method, it not only violates the operating specifications, but also has high labor intensity, high safety and quality risks, and difficult to ensure work efficiency (it is difficult to successfully put the carbon bricks in place once by pushing the method, and it is necessary to lift and lower the carbon bricks many times, and multiple adjustments will repeat the above problems), which is very easy to cause the carbon bricks to be damaged. Due to the high price of carbon bricks, the purchase of spare bricks is limited when ordering. If the carbon bricks are damaged, re-ordering will have a great impact on the construction period and cost. Utility Model Content

[0003] In view of the above problems, the utility model provides a blast furnace lining ring carbon brick construction tool.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1 , Figure 2 As shown, a blast furnace lining ring carbon brick construction tool includes a main rod 6, a first lifting ear 4 and a second lifting ear 9. The first lifting ear 4 is fixed to one end of the main rod 6 and is connected with a lifting rope for connecting the carbon brick 3; the second lifting ear 9 is arranged in the middle of the main rod 6, and the second lifting ear 9 is connected with a lifting rope, and an electric hoist 2 for pulling the lifting rope is installed on the construction protection shed.

[0026] The sling is a steel wire rope or a nylon sling. The steel wire rope or the nylon sling has a high tensile strength.

[0027] Reference Figure 1 and Figure 2 The second lifting lug 9 is connected with a sliding sleeve 5, and the sliding sleeve 5 is slidingly sleeved on the main rod 6. The main rod 6 is provided with a locking member for locking the position of the sliding sleeve 5. The locking member includes a bolt that penetrates the sliding sleeve 5 and the main rod 6 along the radial direction of the main rod 6, and the bolt is threadedly connected with a nut. The arrangement of the bolt and the nut enables the sliding sleeve 5 to be better fixed on the main rod 6 and is not easy to loosen.

[0028] Reference Figure 2 The main rod 6 is provided with a bolt hole 8 for the bolt to pass through, and the sliding sleeve 5 is provided with a through hole 10 for the bolt to pass through, and the bolt hole 8 has the same aperture as the through hole 10. Five bolt holes 8 are provided on the main rod 6, and the five bolt holes 8 are arranged in sequence along the length direction of the main rod 6. The provision of five bolt holes 8 is conducive to adjusting the position of the sliding sleeve 5 under different working conditions, so that the carbon bricks 3 can be lifted vertically.

[0029] Reference Figure 2 , a handrail 7 is fixedly connected to one end of the main rod 6 away from the first lifting ear 4. The handrail 7 is used to facilitate multiple workers to operate at the same time, which is more labor-saving. The distance between the handrail 7 and the sliding sleeve 5 is greater than the distance between the first lifting ear 4 and the sliding sleeve 5. Using the lever principle, the worker operates at the other end of the first lifting ear 4, which is more labor-saving.

[0030] When laying the carbon bricks around the furnace bottom and the annular carbon bricks in the furnace cylinder, adjust the position of the sliding sleeve 5 according to the working conditions, align the through hole 10 with the bolt hole 8, and tighten with bolts. Then use a wire rope or nylon sling to connect the hook of the electric hoist 2 of the construction protection shed with the second lifting ear 9, and connect the first lifting ear 4 with the carbon brick 3. Three masonry workers hold the handrail 7, and two masonry workers hold the carbon brick 3, and put the carbon brick 3 in place one by one. Since the hook of the electric hoist 2 is located in the middle of the main rod 6, the lifting rope can be lifted vertically at a position away from the air outlet sleeve 1, and the carbon brick 3 can be smoothly put in place.

[0031] The utility model provides a blast furnace lining ring-laying carbon brick construction tool, which is designed with a sliding sleeve to adjust the fulcrum position, and is applied to different working conditions and utilizes the lever principle to reduce labor intensity and reduce labor quotas; the new ring-laying carbon brick tool is combined with a traditional blast furnace protection shed electric hoist to work in coordination, thereby eliminating the external pulling and oblique lifting and illegal operations during traditional ring-laying, and reducing the number of repeated adjustments of carbon bricks.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
