Description

Technical Field

[0001] This utility model relates to the field of refractory material production technology, and in particular to a steel structure arch frame used for building large arch bricks in glass melting furnaces. Background Technology

[0002] The bricks used for the large arch bricks of melting furnaces are small and lightweight, making them easy to transport and lay. Wooden arch supports are generally sufficient for laying these bricks. However, with the development of oxygen-based glass melting furnace technology, large arch bricks now often use cast zirconia and corundum or cast alumina. These bricks are typically truncated pyramidal in shape, wider at the top and narrower at the bottom. The bricks are larger and heavier, making transport and laying extremely difficult, and wooden arch supports can no longer withstand the weight during construction.

[0003] Constructing large arches requires perfectly tight joints between bricks. However, once these large and heavy bricks are placed on the arch support surface, their immense weight and friction make movement extremely difficult. Precise millimeter-level adjustments to the bricks' positions are virtually impossible for workers. In practice, they often resort to crude methods such as prying with crowbars or hammering with sledgehammers for positioning. This approach easily causes the expensive cast iron bricks to chip at the edges or suffer internal damage, resulting in material waste and affecting the final construction quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a steel structure arch formwork for laying large arch bricks in glass melting furnaces, which solves the problems of insufficient support strength and difficulty in accurately positioning and adjusting the bricks when laying new heavy large arch bricks using existing arch formwork.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a steel structure arch frame used for constructing the large arch bricks of a glass melting furnace, comprising:

[0006] The circular arc mechanism serves to provide fixed support.

[0007] The support mechanism, installed inside the arc mechanism, is used to support the large arch bricks;

[0008] The support mechanism includes a first nut, the internal threads of which are connected to a hexagonal internal bolt, and one end of the hexagonal internal bolt is provided with a steel ball;

[0009] A horizontal mechanism, mounted on the lower surface of the arc mechanism, is used to support the arc-shaped support mechanism;

[0010] The horizontal mechanism includes two supporting channel steels, which are fixed together by connecting channel steels. The channel steels are fixed together in parallel with their flat surfaces facing upwards and maintaining a consistent horizontal position.

[0011] A stabilizing mechanism, installed inside the horizontal mechanism, is used to support the horizontal mechanism.

[0012] As a further description of the above technical solution:

[0013] The arc mechanism includes two arc-shaped angle steels, which are fixed by multiple connecting angle steels to ensure that the arc surfaces of the arc-shaped angle steels are kept horizontal.

[0014] As a further description of the above technical solution:

[0015] The two curved angle steels have round holes drilled at their center lines according to the width of the arch brick material.

[0016] As a further description of the above technical solution:

[0017] The outer walls of the first nuts are all fixed to the lower surface of the arc-shaped angle steel at the location of the round hole.

[0018] As a further description of the above technical solution:

[0019] One end of the internal hexagonal bolt has an arc groove, the radius and depth of which are greater than the radius of the steel ball.

[0020] As a further description of the above technical solution:

[0021] The upper surfaces of the two supporting channel steels are respectively fixedly connected to the two ends of the two arc-shaped angle steels. Multiple supporting angle steels are fixedly connected between the arc-shaped angle steels and the supporting channel steels. Multiple round holes are symmetrically opened inside the two supporting channel steels.

[0022] As a further description of the above technical solution:

[0023] The stabilizing mechanism includes multiple second nuts, which are evenly fixed on the upper surface of the support channel steel at the location of the circular hole. The internal threads of the second nuts are connected to large bolts.

[0024] As a further description of the above technical solution:

[0025] Four running wheels are symmetrically arranged on the lower surface of the two supporting channel steels.

[0026] This utility model has the following beneficial effects:

[0027] In this invention, firstly, multiple first nuts are fixed to the lower surface of the round hole of the arc-shaped angle steel. Then, the hexagonal bolt is rotated and inserted into the first nut to adjust the distance between it and the large arch brick. The movement of the hexagonal bolt pushes the steel ball to move and contact the large arch brick. The rolling of the steel ball achieves the effect of conveniently moving the large arch brick.

[0028] In this invention, two supporting channel steels are fixedly connected to the two ends of two arc-shaped angle steels, and multiple supporting angle steels are fixed between the arc-shaped angle steels and the supporting channel steels, thereby supporting the arc-shaped angle steels. The four running wheels fixed on the lower surface of the supporting channel steels can easily move the supporting channel steels and the arc-shaped angle steels, thus bearing the weight of the large arch bricks and increasing the construction speed of the large arch bricks in the melting furnace.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0037] Reference Figure 1-5 One embodiment of this utility model is a steel structure arch frame used for constructing large arch bricks in a glass melting furnace, comprising:

[0038] The arc mechanism serves as a fixed support; the arc mechanism includes two arc-shaped angle steels 1, which are fixed by multiple connecting angle steels 3 to keep the arc surface of the arc-shaped angle steels 1 horizontal; the arc-shaped angle steels 1 have round holes drilled at the center line of the two angle steels according to the width of the arch brick material;

[0039] Specifically, the curvature of the arc angle steel 1 is manufactured according to the curvature of the main arch. The radius of curvature of the arc angle steel 1 is 10-15mm smaller than that of the main arch. The two arc angle steels 1 are fixed together by multiple connecting angle steels 3 with the arc surface facing upward to ensure that the arc surface is horizontal and consistent. Multiple round holes are opened at the center line position of the two arc angle steels 1. The spacing of the round holes is set according to the width of the main arch brick, so that at least four round holes are aligned with the main arch brick.

[0040] A support mechanism, installed inside the arc mechanism, is used to support the large arch bricks. The support mechanism includes a first nut 10, with a hexagonal bolt 8 threaded inside the first nut 10. One end of the hexagonal bolt 8 is provided with a steel ball 9. The outer walls of multiple first nuts 10 are fixed to the lower surface of the arc angle steel 1 at the position of the circular hole. One end of the hexagonal bolt 8 is provided with an arc groove, the radius and depth of which are greater than the radius of the steel ball 9.

[0041] Specifically, by fixing multiple first nuts 10 to the lower surface of the circular hole of the arc-shaped angle steel 1, the hexagonal bolt 8 is rotated and inserted into the first nut 10. The distance between the hexagonal bolt 8 and the large arch brick is adjusted by rotating the hexagonal bolt 8. A circular groove is set in the hexagonal bolt 8, and a steel ball 9 is installed in the circular groove. The depth and radius of the circular groove are greater than the radius of the steel ball 9. The movement of the hexagonal bolt 8 pushes the steel ball 9 to move and contact the large arch brick. The large arch brick can be easily moved by the rolling of the steel ball 9.

[0042] A horizontal mechanism, mounted on the lower surface of the arc mechanism, is used to support the arc-shaped support mechanism;

[0043] The horizontal mechanism includes two supporting channel steels 2, which are fixed together by connecting channel steels 4. The channel steels are fixed together in parallel with their flat surfaces facing upwards and maintaining a consistent horizontal position. The upper surfaces of the two supporting channel steels 2 are respectively fixedly connected to the two ends of two arc-shaped angle steels 1. Multiple supporting angle steels 5 are fixedly connected between the arc-shaped angle steels 1 and the supporting channel steels 2. Multiple round holes are symmetrically opened inside the two supporting channel steels 2.

[0044] Specifically, the two supporting channel steels 2 are fixed together by multiple connecting channel steels 4 with their flat surfaces facing upwards to ensure horizontal alignment. The two ends of the two supporting channel steels 2 are respectively fixedly connected to the two ends of the two arc-shaped angle steels 1. Multiple supporting angle steels 5 are fixed between the arc-shaped angle steels 1 and the supporting channel steels 2 to support the arc-shaped angle steels 1. Multiple round holes are symmetrically opened inside the two supporting channel steels 2 according to the span. The diameter of the round holes is larger than the diameter of the bolts.

[0045] A stabilizing mechanism is installed inside the horizontal mechanism to support and stabilize the horizontal mechanism. The stabilizing mechanism includes multiple second nuts 11, which are all fixed to the upper surface of the support channel steel 2 at the position of the round hole. The internal threads of the second nuts 11 are connected to large bolts 6.

[0046] Specifically, by fixing multiple second nuts 11 at the circular holes opened in the support channel steel 2, and screwing the large bolt 6 into the inside of the second nuts 11, the large bolt 6 moves inside the support channel steel 2 and contacts the ground, thereby achieving a supporting effect and improving the stability of the support channel steel 2.

[0047] Four running wheels 7 are symmetrically arranged on the lower surface of the two supporting channel steels 2;

[0048] Specifically, the four running wheels 7 fixed on the lower surface of the support channel steel 2 can be used to easily move the support channel steel 2 and the arc angle steel 1.

[0049] Working principle: First, the running wheel 7 is moved by pushing the supporting channel steel 2, which in turn moves the arc-shaped angle steel 1. Then, the large bolt 6 is rotated inside the second nut 11, so that one end of the large bolt 6 contacts the ground, supporting the supporting channel steel 2 and thus providing stability. The large arch brick is placed on the arc-shaped angle steel 1, and the hexagonal bolt 8 is rotated inside the first nut 10. The movement of the hexagonal bolt 8 pushes the steel balls 9 to move, so that the steel balls 9 contact the large arch brick. The bottom surface of the large arch brick contacts the four steel balls 9. By pushing the large arch brick to move on the steel balls 9, the steel balls 9 roll inside the hexagonal bolt 8, thus facilitating the movement of the large arch brick and avoiding damage to the brick caused by hitting it with a sledgehammer.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
