平に横引きされるようにしている。[Prior Art] Taking the construction of a blast furnace as an example, conventionally, when constructing a blast furnace, a turret is built to the required height, and a main lifting machine installed on the turret or a climbing crane or the like is used to lift the turret to the ground. The construction method used is to take in more iron skin, suspend this iron skin inside the turret, and then pull it horizontally and install it. That is, as shown in Fig. 7, a tower a is erected at the construction location of the blast furnace, and an outrigger, such as a crab trolley that can run in one direction, is installed on the top of the tower as the main lifting device b, or a climbing tower is installed outside the tower. A crane is installed, the split furnace shell placed on the ground is taken in using the above-mentioned club trolley, etc., and suspended to a predetermined height.
In the moving direction of the club trolley, the suspended split steel shell is carried and installed, and since the final form of the blast furnace is cylindrical, the split steel shell is moved away from the above movement direction by a winch installed on tower a. c, chain block d, etc., and since the furnace body is constructed in a hollow conical shape, it is impossible to use only a club trolley, so the steel shell pulled horizontally to the specified position is carried out on a beam in the turret or on the turret. It is being rehanged and installed using a In this case, since the blast furnace will be constructed from the bottom, the steel shell e at the bottom of the blast furnace will first be installed in a divided state and installed in a suspended state. The tuyere skin f is installed by the following operations, and the steel skin g of the morning glory section and the furnace belly is installed in this order, the steel skin h of the shaft, and the steel skin i of the gas collection section are installed in this order, and each of the above parts is installed. During horizontal pulling, the hanging hook j of the main lifting machine b and the steel skin are pulled underground so that the steel skin is pulled horizontally.

等の問題があつた。[Problems to be Solved by the Invention] However, in the conventional construction method described above, horizontal pulling is performed when installing the split steel skin taken in from the ground, so as the installation position of the steel skin moves to the upper part, The angle θ when the wire rope k of the main lifting machine b is pulled horizontally from the vertical state
As the wire rope becomes larger, there is a risk that the wire rope may come off the drum groove and wind up in a disorderly manner.Due to horizontal pulling, the main lifting machine b is installed at a high position, and the weight of the divided steel sheathing increases. Because it weighs over 30 tons and is attached in a conical shape, it requires a huge amount of winches for horizontal pulling, winches for lifting, and accompanying tools and jigs, and it takes a lot of personnel to operate them and the club trolley until the lifting is completed. Since it is not possible to separate the steel, the cost and construction time are enormous.In addition, the height of a single steel shell may be over 7m, which poses a risk of work when rehanging. The number of wires required to handle the shell is slow, so the speed is slow; the lifting machine cannot be removed until the shell is set, which has a large impact on critical processes; There were problems such as the need to select the length of the wire rope according to the height of the steel shell when taking it up to the outrigger, and there were also restrictions on the steel shell division and length.
