[0023] The present disclosure is described more fully below with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are described. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] like Figure 1-2 As shown, the present invention provides a positioning device for installing furnace door casting blocks, which is used for positioning the furnace door and the casting blocks when they are installed, and includes a fixing frame unit and a gap control plate 200, wherein the gap control plate 200 is arranged on the fixing frame unit.

[0025] The fixing frame unit and the gap control plate 200 are used to position the casting material blocks. Through the design of the fixing frame unit and the gap control plate, the installation of the furnace door casting material blocks can achieve higher accuracy, reducing the time and error of manual adjustment.

[0026] In one embodiment, the fixing frame unit includes a cross beam 101, a longitudinal beam 102, a longitudinal beam column 103, a bottom plate 104 and a connecting plate 105. The cross beam 101 and the longitudinal beam 102 form a quadrilateral frame through the connecting plate 105. The longitudinal beam columns 103 are arranged at both ends of the longitudinal beam 102, and the bottom plate 104 is arranged at the bottom of the longitudinal beam columns 103.

[0027] The cross beam 101 and the longitudinal beam 102 form a quadrilateral frame by means including but not limited to bolts and welding to ensure the stability and load-bearing capacity of the structure. The connecting plate 105 is located at the connection between the cross beam 101 and the longitudinal beam 102 to reinforce the connection between the cross beam 101 and the longitudinal beam 102. The longitudinal beam columns 103 are arranged at both ends of the longitudinal beam 102, and the bottom plate 104 is located at the bottom of the longitudinal beam columns 103 to provide support for the entire structure.

[0028] In one embodiment, the fixing frame unit further includes a middle column 106 . The middle column 106 is disposed at the lower end of the beam 101 , and the bottom plate 104 is disposed at the bottom of the middle column 106 .

[0029] In order to accommodate different numbers and sizes of cast blocks, several intermediate columns 106 can be arranged at the bottom of the crossbeam 101, and the bottom plate 104 is located at the bottom of the intermediate columns 106, which further enhances the stability of the fixed frame unit, especially when handling larger or heavier cast blocks, providing additional support. The addition of intermediate columns improves the overall stability and load-bearing capacity of the fixed frame unit, ensuring safety when hoisting heavy objects for installation.

[0030] In one embodiment, the gap control plate 200 is disposed on the beam 101 .

[0031] In order to adapt to casting blocks of different sizes and shapes, a gap control plate 200 is provided on the beam 101. The width of the gap control plate 200 is determined by the thickness of the ceramic fiber blanket provided on the casting block and the position of the casting block in the furnace door. The gap control plate 200 can also be designed to be adjustable. A slide rail is provided on the beam 101 so that the gap control plate 200 can be moved within a certain range and fixed at a desired position by a locking mechanism to meet different installation requirements.

[0032] In one embodiment, the connecting plate 105 contacts the outer wall of the furnace door 300 to limit the position of the furnace door 300 .

[0033] The connecting plate 105 can not only fix the cross beam 101 and the longitudinal beam 102, but also limit the furnace door 300 by controlling the tilt angle, so as to ensure that the furnace door can be accurately positioned during installation.

[0034] like Figure 3 As shown, in order to facilitate the use of a positioning device for installing a furnace door casting block provided by the present disclosure, the present disclosure also provides a construction method for installing a furnace door casting block, including:

[0035] S100, hoisting the casting block to the planned position in the fixed frame unit;

[0036] Assemble the positioning device at the construction site, ensure that all parts are firmly connected, check whether the gap control plate is in the correct position, and prepare the required casting blocks, ceramic fiber blankets, cranes and other necessary tools and equipment. Use the crane to lift the first casting block to the planned position in the fixed frame unit, ensuring that the casting block is located between the longitudinal beam 102 and the gap control plate 200 to ensure the correct spacing.

[0037] S200, installing a ceramic fiber blanket on a surface of the castable block adjacent to other castable blocks;

[0038] Install a ceramic fiber blanket on the surface of the first castable block adjacent to other castable blocks. The ceramic fiber blanket can not only play a role in heat insulation, but also fill possible tiny gaps to improve sealing. Make sure that the ceramic fiber blanket fits tightly to the surface of the castable block, but do not over-compress it so as not to affect its thermal insulation performance.

[0039] S300, hoisting another casting material block to a position adjacent to the previous casting material block in the fixing frame unit;

[0040] Another castable block is hoisted to a position adjacent to the previous castable block in the fixing frame unit, ensuring that the castable block is located between the gap control plates 200, and the ceramic fiber blanket is installed again.

[0041] S400, repeat the above steps until all the casting blocks are placed, hoist the furnace door 300 to the corresponding position above the casting blocks, and install it with the casting blocks.

[0042] Repeat the above steps to place all the casting blocks in sequence until all the installation is completed. The position and gap of the casting blocks should be carefully checked at each step to ensure that they meet the design requirements. When all the casting blocks are correctly placed, use a crane to lift the furnace door 300 and slowly lower it to the corresponding position above the casting blocks. The furnace door 300 is limited by the connection plate 105 in contact with the outer wall of the furnace door 300 to ensure that it is accurately installed on the casting blocks. After the installation is completed, check the fit between the furnace door 300 and the casting blocks, and make fine adjustments if necessary to ensure the best sealing effect. A complete set of construction methods is proposed, from the hoisting of the casting blocks, the installation of the ceramic fiber blanket to the final positioning of the furnace door, which simplifies the construction steps and improves work efficiency.

[0043] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention.
