Description

Technical Field

[0001] This utility model belongs to the field of coking oven construction technology, specifically relating to a device for positioning longitudinal tension bars in a coking oven. Background Technology

[0002] After the brickwork of a newly built coke oven is completed, the protective iron components are installed. During this stage, the longitudinal tie bars are installed. However, as the coke oven is dried, the oven body expands upwards, affecting the installation height of the tie bars. To solve this problem, shims are often placed in the tie bar grooves during construction, and their height is changed periodically to roughly ensure the installation height of the tie bars. However, since the tie bar grooves are slightly larger than the tie bars, this is extremely inconvenient and requires numerous adjustments. Each adjustment of the shim height requires multiple people working together, which is time-consuming, inefficient, and wastes manpower. Therefore, this invention provides a convenient, adjustable, and easy-to-operate installation device that greatly improves work efficiency and reduces labor intensity. Utility Model Content

[0003] The purpose of this invention is to provide a novel coke oven longitudinal tie bar installation and adjustment device. This device can accurately adjust the tie bars according to the expansion of the oven body during oven drying, and can monitor the expansion size of the oven body in real time. It is simple and convenient to operate and does not require a large amount of labor.

[0004] To address the aforementioned technical problems, the technical solution of this utility model is as follows:

[0005] A coke oven longitudinal tie bar positioning device includes a fixed base, an adjusting suspension, adjusting screws, a support rod, a hanging rod, a hanging rope, a displacement sensor, a display, a communication cable, and longitudinal tie bars. The fixed base is symmetrically arranged on both sides of the tie bar groove on the top of the coke oven, and multiple sets are evenly arranged along the length of the longitudinal tie bars. The support rod is welded to the adjusting suspension. The adjusting suspension has bolt holes for use with the adjusting screws. The hanging rod is fixed to the support rod. The hanging rope is fixed in the middle of the hanging rod for lifting the longitudinal tie bars. The displacement sensor is placed below the longitudinal tie bars and connected to the display via a communication cable.

[0006] The number of bolt holes on each side of the adjustable suspension shall not be less than two.

[0007] The number of adjusting screws is adapted to the number of bolt holes in the adjusting suspension.

[0008] The adjustment range of the adjusting screw is 200mm to 250mm.

[0009] The beneficial effects of this utility model are as follows:

[0010] This device is installed on both sides of the longitudinal bar adjustment groove for operation, avoiding the problem of limited operating space in traditional coke oven longitudinal bar adjustment. It is simple and convenient to operate, which can improve labor efficiency and reduce the number of operators. At the same time, this device adds real-time displacement monitoring, which can record the furnace body expansion data at any time during construction. On the one hand, it can provide accurate adjustment dimensions, which helps to adjust the bar position. On the other hand, it can also provide auxiliary parameters for oven drying, providing data support for the hot engineering construction of coke oven, thereby ensuring the smooth progress of oven drying.

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0016] like Figure 1 As shown, Figure 2 for Figure 1 The left view shows a coke oven longitudinal tie bar positioning device, including a fixed base 1, an adjusting suspension 2, an adjusting screw 3, a supporting rod 4, a hanging rod 5, a hanging rope 6, a displacement sensor 7, a display 8, a communication cable 9, and longitudinal tie bars 10. The fixed base is symmetrically and firmly arranged on both sides of the tie bar groove on the top of the oven, with multiple sets evenly arranged along the length of the coke oven longitudinal tie bars. The supporting rod is welded to the adjusting suspension. Bolt holes are opened on the adjusting suspension for use with the adjusting screws. The hanging rod is fixed to the supporting rod. The hanging rope is fixed in the middle of the hanging rod for lifting the longitudinal tie bars. The displacement sensor is placed below the longitudinal tie bars and connected to the display via a communication cable.

[0017] The number of bolt holes on each side of the adjustable suspension shall not be less than two.

[0018] The number of adjusting screws is adapted to the number of bolt holes in the adjusting suspension.

[0019] The adjustment range of the adjusting screw is 200mm to 250mm.

[0020] During the later stages of coke oven construction, as the drying process continues, the coke oven exhibits different expansion trends. To adapt to these expansion changes and ensure that the installation elevation of the longitudinal tie bars is not affected by the oven's expansion, the expansion amount of the oven can be observed and recorded in a timely manner using displacement sensors and displays according to the established drying plan. Then, the corresponding amount can be adjusted downwards by adjusting the screws, thereby ensuring that the installation position of the longitudinal tie bars remains unchanged until the drying stage is completed. At the same time, the real-time monitoring by the displacement display can also generate a trend chart of the oven's expansion amount as the temperature rises. This data can also corroborate manual data measurements and is more helpful for controlling the drying process.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
