[0005]
[Problems to be solved by the invention]
However, in the former (paragraph 0003) heavy article installation device and method for placing and storing a heavy article on a gantry, the heavy article is hung by a crane or the like and placed on the heavy article placement plate of the heavy article installation device, or The heavy load installation device itself is a forklift. A heavy load placing plate is provided on the arm of the forklift, and the heavy load is placed on the heavy load placing plate.
When using a forklift, when placing it on the upper part of the battery storage package as shown in FIG. 10, since there is about 3 tons of battery modules, it cannot be lifted unless it is a large forklift. However, the large forklift (with its own weight 12t) is too large to be suspended by a crane via a normal underground entrance hatch. Even if a large forklift is used, there is about 3.5m up to the uppermost level in FIG. 10, so when trying to lift a battery module of about 3t to the uppermost level, there are two forklift fulcrums. In addition, the battery module cannot be supported by the weight of the forklift, and the forklift is likely to rotate forward, resulting in an extremely unstable state.
When hanging a battery module using a crane, it can only be used in a building where the crane is installed on the ceiling, so when installing in a narrow space such as a basement, the crane is installed. It is not possible to install because For this reason, the current situation is that a chain must be hung on the end of the ceiling of the basement, such as an H-pile, and lifted manually for a long time.
In addition, during the work of transferring heavy objects to the gantry using these heavy object installation devices using forklifts, the heavy object placement plate of the heavy object installation device must be completely free of heavy objects. The heavy object placement device cannot be moved in order to place the heavy object on the heavy object placement device. Therefore, it takes a lot of time to place a large number of heavy objects on these multi-stage and multi-row mounts, which is extremely inefficient.
[0006]
Also, in the heavy equipment installation device of the latter (paragraph 0004), in the work in the basement, the heavy goods are loaded directly on the heavy goods placement plate of the wheeled carriage from the ground crane through the underground entrance hatch. A heavy object is placed on a wheeled carriage, traveled on a rail, transported to the frame, and then the heavy object on the heavy object loading plate of the wheeled carriage is placed on the heavy object loading shelf of the frame. However, when this work is finished and the wheeled carriage becomes empty, the wheeled carriage must be run to load the next heavy object, and the heavy object must be placed there. In addition, when placing a heavy object on the top of the pedestal, attach one support base on the wheeled carriage, and when placing a heavy support on the top tier, attach two support bases and The height of the object mounting board must be matched. When removing a heavy object from the gantry, the reverse procedure is performed after removing the support so as to match the height of the heavy object placing plate. Therefore, when carrying heavy objects on a carriage one by one, carrying them from the bottom of the hatch to the gantry, and then installing them on the gantry, when placing them on a gantry of different height, It is necessary to attach the necessary number of support stands to the carriage when it is placed on the carriage. For this reason, it takes a lot of work time to install a large number of heavy objects on a multi-stage, multi-row frame.
[0007]
In view of this, the present invention is provided with a carriage separately from the heavy equipment installation jig for transferring a heavy article to the gantry, and the trolley is moved between the operations of transferring the heavy article to the gantry, and the heavy article is mounted on the trolley. In addition, an object of the present invention is to provide an operation method for returning a large number of heavy objects to a gantry in a short time and an apparatus used for the method, and to return the heavy object installation jig to the place, and to solve the above-mentioned problems.
