Description

Technical Field

[0001] The invention relates to the technical field of coke side furnace protection, and in particular to a coke side furnace protection iron piece track site crane lifting structure. Background Art

[0002] In the past, during the installation of coke ovens, when installing the iron parts on the coke side of the coke oven, it was necessary to stand a truck crane inside the quenching car track on the coke side. Due to the complexity of the process, the space on the coke side of the coke oven is extremely insufficient. For example, there are two quenching car tracks and a coke platform on the coke side for wet quenching, and two coke blocking car tracks and a quenching car track for dry quenching. As a result, there is no space outside the coke side track to transport and place the iron parts for the furnace protection equipment, and most lifting machinery and equipment cannot be supported and set up after entering the site.

[0003] In the past, after the coke oven was built, the next construction process required was the installation and debugging of the furnace protection iron parts. In the previous construction process, when installing to the coke side of the coke oven, a truck crane was required to enter the inside of the quenching car track on the coke side of the coke oven. The crane model is generally 25-75t. Taking a 25t crane as an example, the outrigger width is 6m, and the center distance between the inner and outer rails of the quenching car is 4 meters (the center distance between the inner and outer rails of the 6.25m, 6.75m, and 7.65m models of coke ovens is 4m). The crane leg width is insufficient, and the quenching car track is a pedestal track foundation. The height difference from the pedestal surface to the upper surface of the track beam is 700mm-2100mm (the height difference varies depending on the different design heights of the ground, and the final ground is generally 700mm), and the crane leg height is also limited. The outside of the inner track of the quenching car on the coke side of the coke oven is the flue on the coke side of the coke oven, which is less than one meter away. The outside of the outer track of the quenching car is the coke blocking car track or coke platform, which is less than 3 meters away from the outer track. The height difference between the flue, coke blocking car track, coke platform and the track is more than 3.5 meters, and the extended width varies from 4 to 10 meters. It is impossible to place equipment and materials, and vehicles cannot pass, so operations can only be carried out between the inner and outer tracks of the quenching car.

[0004] At present, a 25-75t truck crane is first placed between the inner and outer rails of the coke quenching car to set up the legs at the lifting operation point. After the truck crane is set up, the truck carrying the furnace protection iron parts equipment is placed on the plate for lifting. However, the width and height of the coke oven quenching car track are limited, and even a crane of at least 25t cannot be set up, so this patent is used to solve the problem.
