Description

Technical Field

[0001] This utility model belongs to the field of metallurgical construction technology, and in particular relates to a positioning device for installing casting blocks for furnace doors. Background Technology

[0002] In coking equipment installation, the coke oven door is a crucial piece of equipment, and the castable blocks are a key component of the door. The door operates frequently in high-temperature and harsh environments during production. The average weight of the castable blocks for large tamped coke ovens exceeds 500 kg, requiring a set of M32 bolts for installation between the blocks and the door, with high precision in bolt positioning. This weight makes installation extremely labor-intensive, necessitating the use of large cranes and other equipment, increasing construction difficulty and cost. Installation quality directly affects coke quality and the coke oven's lifespan, and may result in non-compliance with environmental standards during production. During construction, the ceramic fiber blanket is prone to displacement, leading to increased gaps between castable blocks, misalignment of machined bolt holes, and large dimensional errors in the positioning and installation of the castable blocks. Lack of control over these issues makes subsequent adjustments difficult and can result in the inability to securely install the blocks to the door.

[0003] Existing installation methods primarily involve on-site construction on a hard surface, laying out the blocks according to installation dimensions, and then manually securing them with pry bars. This method has several drawbacks: increased labor costs and reduced efficiency; poor installation accuracy and quality, leading to cumulative installation errors; severe damage to the glaze layer of the material, resulting in material waste; and the emission of harmful gases during production, polluting the environment. Therefore, there is an urgent need for a positioning device for installing furnace door casting blocks that can solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a positioning device for installing casting blocks for furnace doors, which is particularly suitable for positioning during the installation of casting blocks for coke oven doors.

[0005] The technical solution adopted by this utility model is as follows: Firstly, a positioning device for installing furnace door casting blocks is provided for positioning the furnace door and casting blocks during installation. The device includes a fixing frame unit and a gap control plate, wherein the gap control plate is disposed on the fixing frame unit.

[0006] Furthermore, the fixed frame unit includes a crossbeam, a longitudinal beam, longitudinal beam columns, a base plate, and a connecting plate. The crossbeam and the longitudinal beam form a quadrilateral frame through the connecting plate. The longitudinal beam columns are located at both ends of the longitudinal beam, and the base plate is located at the bottom of the longitudinal beam columns.

[0007] Furthermore, the fixing frame unit also includes an intermediate column, which is disposed at the lower end of the crossbeam, and the base plate is disposed at the bottom of the intermediate column.

[0008] Furthermore, the gap control plate is disposed on the crossbeam.

[0009] Furthermore, the connecting plate contacts the outer wall of the furnace door to limit the movement of the furnace door.

[0010] The advantages and positive effects of this utility model are as follows: By adopting the above technical solution and through the design of the fixing frame unit and the gap control plate, the installation of the furnace door casting blocks can achieve higher precision, reducing the time and error of manual adjustment; the addition of the intermediate column improves the overall stability and load-bearing capacity of the fixing frame unit, ensuring safety when hoisting heavy objects for installation; a complete construction method is proposed, from the hoisting of the casting blocks and the installation of the ceramic fiber blanket to the final positioning of the furnace door, simplifying the construction steps and improving work efficiency.

[0017] The present disclosure will now be described more fully with reference to the accompanying drawings, which illustrate exemplary embodiments of the present disclosure. The technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative effort are within the scope of protection of the present disclosure.

[0018] like Figure 1-2 As shown, this utility model provides a positioning device for installing furnace door casting blocks, used for positioning the furnace door and casting blocks during installation. It includes a fixing frame unit and a gap control plate 200, with the gap control plate 200 disposed on the fixing frame unit.

[0019] The fixing frame unit and gap control plate 200 are used to position the castable blocks. The design of the fixing frame unit and gap control plate allows for higher precision installation of the castable blocks at the furnace door, reducing the time and error associated with manual adjustments.

[0020] In one embodiment, the fixing frame unit includes a crossbeam 101, a longitudinal beam 102, a longitudinal beam column 103, a base plate 104, and a connecting plate 105. The crossbeam 101 and the longitudinal beam 102 form a quadrilateral frame through the connecting plate 105. The longitudinal beam column 103 is disposed at both ends of the longitudinal beam 102, and the base plate 104 is disposed at the bottom of the longitudinal beam column 103.

[0021] The crossbeam 101 and the longitudinal beam 102 are assembled into 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 crossbeam 101 and the longitudinal beam 102 and serves to reinforce the connection between the crossbeam 101 and the longitudinal beam 102. The longitudinal beam column 103 is set at both ends of the longitudinal beam 102, and the base plate 104 is located at the bottom of the longitudinal beam column 103 to provide support for the entire structure.

[0022] In one embodiment, the fixing frame unit further includes an intermediate column 106, which is disposed at the lower end of the crossbeam 101, and a base plate 104 is disposed at the bottom of the intermediate column 106.

[0023] To accommodate different quantities and sizes of castable refractory blocks, several intermediate columns 106 can be installed under the crossbeam 101, with the base plate 104 located at the bottom of the intermediate columns 106. This further enhances the stability of the fixing frame unit, providing additional support, especially when handling larger or heavier castable refractory blocks. The addition of intermediate columns improves the overall stability and load-bearing capacity of the fixing frame unit, ensuring safety during installation when hoisting heavy objects.

[0024] In one embodiment, a gap control plate 200 is disposed on a crossbeam 101.

[0025] To accommodate casting blocks of different sizes and shapes, a gap control plate 200 is provided on the crossbeam 101. The width of the gap control plate 200 is determined by the thickness of the ceramic fiber blanket set 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, with a slide rail provided on the crossbeam 101, so that the gap control plate 200 can move within a certain range and be fixed in the required position by a locking mechanism to meet different installation requirements.

[0026] In one embodiment, the connecting plate 105 contacts the outer wall of the furnace door 300 to limit the furnace door 300.

[0027] While fixing the crossbeam 101 and the longitudinal beam 102, the connecting plate 105 can also limit the furnace door 300 by controlling the tilt angle, ensuring that the furnace door can be accurately positioned during installation.

[0028] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
