Problems solved by technology

Therefore, when the distance between the side rollers is increased, the liftable distance of the lift section is shortened, and the storage efficiency of goods decreases.
[0011] Therefore, in existing tower cranes, it is not possible to increase the distance between the side rollers, but to increase the rigidity of the support body supporting the side rollers, or to increase the rigidity of the side rollers themselves to withstand the offset load at the time of delivery. structure

no. 1 Embodiment approach

[0040] figure 1 It is a top view of the automatic warehouse S equipped with the tower crane of this embodiment. figure 2 It is a side view of the automatic warehouse S.

[0041] As shown in the figure, the automatic warehouse S includes a tower crane C and racks T1 and T2 arranged opposite to each other across a guide rail R serving as a track for the tower crane C, and the tower crane C transports goods to the racks. Stored on T1 and T2. Furthermore, the automatic warehouse S is equipped with a storage conveyor (not shown) for storing goods in and a delivery conveyor (not shown) for taking goods out of the warehouse, and the tower crane C can Cargo is handed over between the inbound conveyor and the outbound conveyor.

[0042] In addition, in the present embodiment, the cargo is a cargo box X for accommodating a plurality of glass substrates, and the racks T1 and T2 and the tower crane C are arranged in a clean room CL1 with a degree of cleanliness of 10 degrees, for exam...

no. 2 Embodiment approach

[0081] Hereinafter, the second embodiment of the present invention will be described, and in the description of the second embodiment, the description of the same parts as those of the first embodiment will be omitted or simplified.

[0082] Figure 9 It is the perspective view which looked at the state which the lifting frame 40 descended from the downward direction in the tower crane of this embodiment.

[0083] In the above-mentioned first embodiment, the space between the guide part 70a and the guide part 70b is lengthened compared with the prior art, so the side frame 43 itself is made long in the up-down direction.

[0084] And in the tower crane of this embodiment, as Figure 9 As shown, the side frame 43 is not lengthened, but the lower guide portion 70b is configured to protrude downward of the side frame.

[0085] Specifically, the guide part 70b is fixed to the support body 80 extending downward from the side frame 43, the support body 80 is reinforced by the rib ...

no. 3 Embodiment approach

[0089] Hereinafter, a third embodiment of the present invention will be described technically. In addition, in the description of the third embodiment, the description of the same parts as those of the first embodiment or the second embodiment will be omitted or simplified.

[0090] Figure 10It is the perspective view which looked at the state which the lifting frame 40 descended from the downward direction in the tower crane of this embodiment.

[0091] As shown in the figure, in the tower crane according to the present embodiment, the lower guide portion 70b is protrudingly provided below the side frame as in the above-mentioned second embodiment. Moreover, in the tower crane of this embodiment, the lower frame 10 is not formed in a frame shape, but the penetration part 10b through which only the guide part 70b, the support body 80, and the reinforcement rib 90 can pass is formed.

[0092] According to the tower crane of the present embodiment having such a structure, whe...

Abstract

A stacker crane in which a mast (20) is extended below from an upper surface of a lower frame (10), guide sections (70a, 70b) capable of moving while sliding on a wall surface of the mast (20) are arranged in the direction of up and down of a lifting section, and the lower frame (10) has a guide section movement region (A) in which the lowermost guide section (70b) of the guide sections (70a, 70b)is movable downward from the level of the upper surface of the lower frame (10). The guide sections can be separated from each other without a decrease in receiving efficiency of goods in an automatic warehouse.

Description

technical field [0001] The present invention relates to a tower crane, and more particularly, to a tower crane including a guide part that can slide and move on a column erected on a lower frame. [0002] This application claims the priority of Japanese Patent Application No. 2007-166000 filed in Japan on June 25, 2007, and uses the content here. Background technique [0003] For example, in an automatic warehouse in which goods are stored on a plurality of storage racks arranged vertically and horizontally, goods are transported using tower cranes. Such a tower crane can travel on rails provided along cargo storage racks, and use a driving device to raise and lower a lifting frame suspended by a lifting cable to transfer cargo between arbitrary storage racks. [0004] This type of tower crane includes a column erected on a lower frame, and side rollers (guide sections) that can move up and down by sliding relative to the column are provided on the elevating section so that...
