Problems solved by technology
Since the coke-side operating platform (concrete or steel structure) of the super-large coke oven is constructed first, the switch switch below it cannot be installed with a crane or a crane. Most of the current installation methods use a ground flatbed truck to install the switch. Enter the platform, use manual pull to the intermediate platform position, use hand chain hoists to start installation in sequence, the installation time is long, and the installation cost is relatively high
[0004] Therefore, there are above-mentioned inconveniences and problems in the known extra-large coke oven exchange switch installation method

Embodiment 1
[0029] The installation method of the extra-large coke oven exchange switch of the present invention, each exchange switch weighs 3.87t, comprises the following steps:
[0030] a. Set electric hoist track beam
[0031] see now Figure 1 to Figure 3 , figure 1 It is a schematic diagram of the configuration of the extra-large coke oven exchange switch of the embodiment of the present invention, figure 2 for figure 1 The sectional view of A-A in, image 3 for figure 2 Schematic diagram of the device in direction B. Directly above the flue elbow on the coke side of the super-large coke oven, under the coke side operating platform arranged parallel to each other, a cantilever beam is horizontally erected at both ends of several coke oven exchange switches arranged longitudinally along the furnace length As the electric hoist track beam, the distance between the two beams is 3.3m, each exchange switch is between the two beams, the length of the cantilever beam is 112.2m, and...

The invention provides an installation method of super-huge type coke oven exchange shutters. The weight of each exchange shutter is 3.87 t. The installation method is characterized by comprising thefollowing steps of a, arranging an electric hoist track beam; b, installing a 5t electric hoist on the electric hoist track beam; c, starting the electric hoist to hoist the exchange shutters from theside of an end platform; and d, dismantling the electric hoist, a cantilever beam, a connecting plate and a lead screw for reutilization during next installation after completion of installation of all the exchange shutters. The installation method of the super-huge type coke oven exchange shutters has the advantages that the exchange shutters are installed through the electric hoist, and the operation efficiency is substantially improved; the labor cost is less; the installation quality of the exchange shutters is good, the one-time installation qualified rate is high, and there is no need to implement repeated adjustment in the installation process.
Description
technical field [0001] The invention relates to a method for installing an extra-large coke oven exchange switch, in particular. Background technique [0002] As an important equipment for coking, the coke oven is an extremely complex industrial furnace. With the development of science and technology, its structure is continuously improved and perfected, and it is developing towards a large volume. The domestic coke oven has developed from the early 4.3m coke oven to the current 7.65m coke oven, in which the exchange switch is one of the important coke oven equipment, and the waste gas generated during the coking process of the coke oven is discharged to the flue through the switch , the air required for combustion enters the furnace through the switch. [0003] The extra-large coke oven exchange switch is only arranged on the coke side of the coke oven, arranged longitudinally along the length of the oven, and the distance is relatively long. Since the coke-side operating...
