Problems solved by technology

At present, most of the installation methods use manual, greenhouse driving and other mechanical methods to slowly move from the machine side to the focal side. The threaded fasteners at the end of the lower brace must be protected separately, which takes a long time and costs a lot.
[0003] Therefore there are above-mentioned various inconveniences and problems in the installation mode of the lower horizontal bracing of the known extra-large coke oven

Embodiment 1

[0036] In the method for installing horizontal braces at the lower part of an extra-large coke oven according to the present invention, the braces run through the entire hearth plate from the coke side to the machine side. The length of the hearth plate is 18660mm, the length of the braces is 21135mm, and the weight is greater than 430kg. The material is Q345B. Include the following steps:

[0037] a. Pulling device for making braces

[0038] see now Figure 1-Figure 3 , figure 1 It is a schematic structural diagram of the drawing device according to the embodiment of the present invention, figure 2 for figure 1 A schematic diagram of image 3 for figure 1 B direction schematic diagram. As shown in the figure, use a steel pipe to make a short pipe 6 with an inner threaded buckle at one end. The steel pipe is φ65*7.5mm and the length is 200mm, so that the inner threaded buckle 11 of the short pipe can match the outer threaded buckle at the end of the tie rod 7. An ear p...

Abstract

The invention provides a mounting method of a lower cross brace of an ultra-large coke oven. The brace penetrates through a whole furnace bed plate from a coke side to a machine side, the length of the brace is greater than or equal to 21135mmm, the weight of the brace is greater than or equal to 430kg and the brace is made of Q345B; the mounting method is characterized by comprising the followingsteps: a, manufacturing a drawing device of the brace; b, providing a winch; c, connecting the drawing device; d, mounting the lower cross brace of the coke oven; and pulling one section of the braceand adjusting and moving the position of a winch base until the mounting work of the brace is finished. The mounting method of the lower cross brace of the ultra-large coke oven, provided by the invention, has the advantages that the drawing device is simple in structure and convenient to manufacture and a pulling device can be used for realizing the effect of protecting a screw thread; the windlass is used for carrying out pulling work and the working efficiency is greatly improved; and the labor cost is less and the installation engineering cost is reduced.

Description

technical field [0001] The invention relates to a method for installing a horizontal brace at the lower part of a coke oven, in particular to a method for installing a horizontal brace at the lower part of an extra-large coke oven. Background technique [0002] As an important equipment for coking, the coke oven is an extremely complicated industrial furnace. With the development of science and technology, its structure is continuously improved and perfected, and it is developing in the direction of large volume. Domestic coke ovens have developed from the early 4.3m coke ovens to the current 7.65m coke ovens, in which the furnace column is one of the important furnace protection equipment, and the machine and coke side furnace columns are fixed by upper and lower tie bars. Small and medium-sized The lower brace of the coke oven is a short brace, which is relatively easy to install. The lower brace of a super-large coke oven is a long brace, which needs to pass through the ...
