Abstract

PURPOSE:To effectively use a floor area and the like by running a stacker crane on a running rail between a shelf and carrying in/out part, mounting an elevator on the stacker crane, and mounting both a cargo-holding means and a holding carriage which is provided with a traveling means to the shelf, on the elevator. CONSTITUTION:When a segment carrying-in truck 46 enters a segment carrying-in part 45, a traveling carriage 9 of a stacker crane 8 is run in the direction of an arrow-mark A and stopped over the carrying-in part 45. Next, an elevator 11 is lowered, so that the elevator 11 is held to a tongs carriage 19 by means of a holding-arm 29 of the tongs carriage 19. After this, the tongs carriage 19 is moved to a housing part 42 and stopped therein, taking advantage of elevating motion of the elevator 11 and traveling motion of the traveling carriage 9 in the direction of B. Next, the crane-side rail is brought in line with the shelf-side rail, and the tongs carriage 19 is moved to the shelf side and shifted over a pedestal 43 of the shelf. In the case of carrying out, the above procedure is reversed.

Then, the elevating body is raised and the traveling frame is moved to stop at a position where the crane side rail of the elevating body is continuous with the shelf side rail in front of the shelf. Then, after moving the holding cart and transferring it from the crane side rail to the shelf side rail,
The load is released from the holding arm and stored on the shelf, and the holding cart is returned from the shelf side rail to the crane side rail. The shipping process is performed in the reverse order of the warehousing process. Therefore, even if there are obstacles such as structures or equipment below the transport path, the load can be transported. In addition, since loads are loaded and unloaded onto the shelves by moving the holding cart to the shelf side rail, no cantilever load is applied to the elevating body of the stacker crane, and even heavy loads can be transferred smoothly.

In the configuration of the second invention, when carrying a load from the carry-in mountain part to the shelf, the running frame of the stacker crane runs along the running rail, stops above the carry-in part, and lowers the hanging body to hold it. The load is held by the holding arm of the cart. Then, the suspended body is raised and the traveling frame is run,
In front of the shelf, the crane side rail of the hanging body stops at a position where it is continuous with the shelf side rail. After the holding cart is moved and transferred from the crane side rail to the shelf side rail, the load is released from the holding arm and stored on the shelf, and the holding cart is returned from the shelf side rail to the crane side rail.

When transporting loads from the shelves to the shaft, the stacker crane takes out the loads from the shelves in the reverse order to the above, and then the traveling platform is moved to the upper part of the shaft. After the hanging body is lowered to the lower limit position of the guide post, the guide post and the hanging body are separated, and the rope of the winch is let out to lower the hanging body into the shaft. When the bottom of the shaft is reached, the holding arm is released to unload the load, and the hanging body is raised and connected to the guide post. When transporting cargo from the shaft to the shelves, perform the procedure in reverse order. It is also possible to carry unloaded cargo in and out between the other two loading mountain sections and the shaft. Therefore, since the hanging body is connected to the guide post when loading and unloading the load from the shelf, the hanging body can be accurately positioned facing the shelf side rail. Furthermore, since the holding cart is transferred from the crane side rail to the shelf side rail, no cantilever load is applied to the crane side, and even heavy loads can be transferred smoothly.

Furthermore, when carrying in and out of the shaft, the guide post and the hanging body are separated and only the hanging body is lowered, making it easy to handle cargo at high heights. Furthermore, cargo handling can be carried out between the loading pile, the shelf and the shaft using a single stacker crane, resulting in lower costs and shorter cycle times, and the effective use of the ground surface (floor surface) below the transport route. .

According to the above embodiment, (1) segment loading truck 4;
The stocking operation from the loading platform 6 to the shelf 41 and the carrying operation from the shelf 41 to the bottom of the starting shaft 3 can be performed with one stacker crane, resulting in low cost. (2) Compared to using conventional overhead cranes and forklifts, the cargo handling line is simple, with no segment 31 transfers along the way;
Cycle time can be shortened and safety can be improved. (Since the 31-stack crane 8 is a suspended type that runs on the traveling rail 4 arranged above the ground 7, the installation ground 7 can be used effectively, and equipment can be installed below the segment transport route 1. (4) When loading the segment onto the shelf 41, the lifting frame 15 is guided by the guide post 14.
Since the work is carried out with the and hanging body 17 fixed by the fixing device 23, the positioning of the elevating body 11 can be performed accurately. (
5) When inserting the segment into the starting shaft 3, the lifting frame 15 and the hanging body 17 are separated and only the hanging body 17 is lowered, so it is easy to carry the hanging body 17 into the mine at an extremely high height. You can work safely because you are guided by the cell guide 50. (When stocking the 6J segment 31, move the tongs cart 19 to the crane side rail 24 of the hanging body 17.
Since the load is transferred from the stacker crane to the storage section 42 by moving the load onto the shelf side rail 44, a cantilever load is applied to the crane side, compared to a stacker crane that transfers the load by moving a fork or the like toward the shelf side. Therefore, the heavy segment 31 can be transferred extremely smoothly.

Effects of the Invention As described above, according to the warehouse equipment of the first invention, the stacker crane is guided by a traveling mount that runs on a traveling rail above the ground (floor surface) and a guide post below the traveling mount. Since a lifting body is provided, the load can be transported even if there are obstacles such as structures or equipment below the transport route.

Further, according to the loading/unloading stage @ of the second invention, loading and unloading of loads to/from the shelf is performed by connecting the hanging body to the guide post.
The hanging body can be accurately positioned with respect to the shelf, and the holding cart is transferred from the crane side rail to the shelf side rail, so no cantilever load is applied to the crane side.
Even heavy loads can be transferred smoothly. Further, when carrying the cargo into and out of the shaft, the guide post and the hanging body are separated and only the hanging body is lowered, making it easy to handle cargo at high heights. Furthermore, since a single stacker crane can perform cargo handling between the loading pile, the shelf, and the shaft, costs can be reduced, cycle time can be shortened, and the ground (floor surface) below the transport route can be used effectively.
