Description

Technical Field

[0001] This utility model relates to the field of metallurgical equipment installation technology, and to an auxiliary tool for hoisting furnace shells. In particular, it relates to an auxiliary tool for hoisting furnace shells that can solve the problem that the tool shackles cannot be inserted due to the large distance between the furnace shell water pipe hole and the upper opening of each section of the furnace shell during current furnace shell installation. Background Technology

[0002] In the metallurgical industry, blast furnace shells or industrial furnace shells need to be assembled in sections. In the past, prefabricated shackles and plate clamps were used as lifting tools. However, according to process requirements, some furnace shells cannot meet the lifting requirements. For example, when installing a new furnace shell section, the cooling wall water pipe holes are generally used as lifting points. However, since the height of each section of the blast furnace shell and the distance of the cooling wall water pipe holes are different, this often results in the shackles not being able to pass through the cooling wall water pipe holes during lifting, which brings difficulties to the furnace shell replacement work.

[0003] Therefore, developing a furnace shell hoisting auxiliary tool that can solve the problem that the tool shackles cannot be inserted due to the large distance between the furnace shell water pipe holes and the top opening of each section of the furnace shell during the current furnace shell installation is of great practical significance. Utility Model Content

[0004] Due to the aforementioned defects in the existing technology, this utility model provides a furnace shell hoisting auxiliary tool that can solve the problem that the tool shackles cannot be inserted due to the large distance between the furnace shell water pipe hole and the top opening of each section of the furnace shell during the current furnace shell installation. Specifically, by optimizing the hoisting point design and using this furnace shell hoisting auxiliary tool, the problem that the current tool shackles cannot be inserted can be overcome, which can significantly improve the installation efficiency and installation accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A furnace shell hoisting auxiliary tool includes a hoisting plate and a hanging plate pin;

[0007] The hoisting plate includes a main body and an insertion part connected to each other. The main body is a flat plate structure and has hoisting holes with the opening direction perpendicular to the plane of the main body. The insertion part is a plate structure and its cross-section matches the opening position on the furnace shell. The insertion part has pin holes with the opening direction perpendicular to the plane of the main body and matching the pin of the hanging plate.

[0008] Both ends of the hanging plate pin have pin hanging holes. By tying or hanging the fixing rope on the two pin hanging holes or inserting the fixing pin on the two pin hanging holes, it can be ensured that the pin will not detach from the hanging plate after the furnace shell hoisting auxiliary tool is installed, thus ensuring the safety of the hoisting process.

[0009] This utility model provides a furnace shell hoisting auxiliary tool with a simple structure and reasonable design. The main body of the hanging plate serves as the hoisting attachment point. After the hanging plate insertion part penetrates the furnace shell through the cooling wall water pipe hole, it is fixed to the furnace shell by the hanging plate pin. It is easy to install, has good applicability, high work efficiency, and short construction cycle, and has great application prospects.

[0010] As a preferred technical solution:

[0011] As described above, in a furnace shell hoisting auxiliary tool, the hanging plate pin is a square pin.

[0012] As described above, in a furnace shell hoisting auxiliary tool, the pin insertion hole is a square hole that matches the hanging plate pin.

[0013] As described above, a homemade auxiliary tool for hoisting a furnace shell includes a hanging plate body comprising a semi-circular plate and a rectangular plate of the same thickness that are connected to each other. The straight edge of the semi-circular plate is connected to one side of the rectangular plate to form a plate-like structure with a smooth edge. The presence of the semi-circular plate can prevent interference between the hook and the hook when the hook rotates around the hoisting hole, thus avoiding damage to the hook.

[0014] As described above, in a furnace shell hoisting auxiliary tool, the hoisting hole is located at the center of a semi-circular plate.

[0015] As described above, in a furnace shell hoisting auxiliary tool, the hanging plate insertion part is coaxial with the hanging plate body and the thickness of the hanging plate insertion part is the same as that of the hanging plate body;

[0016] With the straight edge of the semi-circular plate as the width direction, the width of the insert portion of the hanging plate is smaller than the width of the main body of the hanging plate.

[0017] The above technical solution is only one feasible technical solution of this utility model. The protection scope of this utility model is not limited to this. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0018] The above-mentioned utility model has the following advantages or beneficial effects:

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0029] Example 1

[0030] A furnace shell hoisting auxiliary tool, such as Figures 1-2 As shown, it includes a hoisting plate 2 and a mounting pin 3;

[0031] Hanging plate 2 Figure 3 As shown, the system includes a hanging plate body 23 and a hanging plate insertion part 24 that are connected to each other. The hanging plate body 23 is a flat plate structure. The hanging plate body includes a semi-circular plate and a rectangular plate that are connected to each other and have the same thickness. The straight edge of the semi-circular plate is connected to one side of the rectangular plate to form a plate structure with a smooth edge. The semi-circular plate has a hoisting hole 21 with the opening direction perpendicular to the plane of the hanging plate body 23 and located in the center of the semi-circular plate. The hanging plate insertion part 24 is a plate structure and the cross section of the hanging plate insertion part 24 matches the opening position on the furnace shell 1. The hanging plate insertion part 24 has a pin insertion hole 22 (a square hole that matches the hanging plate pin 3) with the opening direction perpendicular to the plane of the hanging plate body 23 and matching the hanging plate pin 3. The hanging plate insertion part 24 is coaxial with the hanging plate body 23 and has the same thickness as the hanging plate body 23. With the straight edge of the semi-circular plate as the width direction, the width of the hanging plate insertion part 24 is smaller than the width of the hanging plate body 23.

[0032] Mounting pin 3 Figure 4 As shown, it is a square pin with pin hanging holes 31 at both ends.

[0033] Both the hoisting plate 2 and the hanging plate pin 3 are made of low alloy steel plate with a thickness of 30mm.

[0034] The usage methods of the above-mentioned furnace shell hoisting auxiliary tools are as follows:

[0035] First, insert the hanging plate insertion part 22 of the lifting plate 2 into the pre-reserved cooling wall water pipe hole in the furnace shell 1. Then, on the outside of the furnace shell, insert the hanging plate pin 3 into the pin insertion hole 22 on the lifting plate 2 and fix it. Next, insert the fixing pin into the pin hanging hole 31 on the hanging plate pin 3 to ensure that the hanging plate pin 3 does not detach from the lifting plate 2 during operation. The inside of the furnace shell is connected to the shackle for furnace shell lifting. Because the furnace shell has a certain degree of inclination, therefore... Figure 1 The inclination angle located inside the furnace shell depends on the furnace shell.

[0036] Verification has shown that this utility model's furnace shell hoisting auxiliary tool is reasonably designed. It uses the main body of the hanging plate as the hoisting attachment point. The hanging plate insertion part penetrates the furnace shell through the cooling wall water pipe hole and is then fixed to the furnace shell by the hanging plate pin. It is easy to install, has good applicability, high work efficiency, and a short construction cycle. The structure is simple, and all components can be quickly fabricated on-site, resulting in low cost. It is also convenient to use, enabling rapid on-site installation and furnace shell hoisting operations, making it highly promising for future applications.
