Problems solved by technology
[0010] However, in the shock-absorbing structure of the frame disclosed in Patent Document 1, there is a problem that since the ultra-soft steel column made of steel with an ultra-low yield point is used as the lowest part of the column of the frame, there is a problem that it is different from that without the ultra-soft steel column. The frame strength of the column is lower than that of a normal column frame
[0011] That is to say, it is originally a frame that needs to have strength against earthquakes, but since the frame is provided with low-strength parts to absorb the energy of a large earthquake, the strength of the entire frame cannot be avoided.

[0059] Hereinafter, the shock absorbing structure of the storage rack according to the first embodiment will be described with reference to the drawings.
[0060] This embodiment is an example in which the shock-absorbing structure of the storage rack is applied to the storage rack of the automatic warehouse.
[0061] Such as figure 1 As shown, the automatic warehouse 10 includes: a plurality of storage racks 11; a stacking crane 13 reciprocating on rails 12 provided between the storage racks 11; and an above-ground control panel C as a control device.
[0062] The stacker crane 13 serving as an article transfer device conveys the articles W for rearranging the articles W in the storage rack 11 in addition to conveying the articles W between the storage rack 11 and the loading and unloading platform 14 provided at the end of the storage rack 11 .
[0063] The above-ground control panel C performs not only the entry and exit management and inventory management of the articles ...

[0135] The second embodiment differs from the first embodiment in that the hydraulic dampers are installed on the sub-frames, except that steel is used as the horizontal bars connecting the main frame and the sub-frames.
[0136] The other configurations are the same as those of the first embodiment, and for the same configurations, the description of the first embodiment is cited and the same reference numerals are used.
[0137] Such as Figure 7 As shown, the storage frame 31 is equipped with the connection member 32 which is a horizontal diagonal rod which connects the main frame 15 and the subsidiary frame 20. As shown in FIG.
[0138] In the present embodiment, the connecting member 32 is formed of steel.
[0139] On the subsidiary facet 23 of the subsidiary frame 20 , a pair of hydraulic shock absorbers 33 connecting the front and rear subsidiary column members 21 is provided diagonally and obliquely.
[0140] A pair of hydraulic shock absorbers 33 are provided for ea...

Abstract
The invention provides a vibration control strucutre of storage rack, which does not reduce strength of main frame of the storage rack and can efficiently absorb seismic energy by using the vibration control strucutre, thereby fully performing the vibration control property. The storage rack comprises: a main frame , which has a main dimension surrounding a main support part, wherein, the main dimension is arrange dwith a latticed column; an auxiliary frame, which has an auxiliary dimension surrounding an auxiliary support part, wherein, the auxiliary dimension is parallel with the main dimension; and a connecting part which connectes the main frame and the auxiliary frame, wherein, the connecting part is arranged with a hydralic shock absorber.
Description
technical field [0001] The present invention relates to a shock-absorbing structure of a storage rack including a plurality of frames including column members and beam members. Background technique [0002] As a prior art related to the shock absorbing structure of the storage rack, for example, a frame shock absorbing structure disclosed in Patent Document 1 is known. [0003] In the frame damping structure disclosed in Patent Document 1, an automatic warehouse including an outer truss and an inner truss is installed. [0004] The outer truss is constructed by joining together by means of pin joints two vertical columns pinned to column base members and a horizontal bar and a diagonal bar. [0005] Also, the inner truss is constituted by joining together two standing columns, a center column standing between the two columns, a horizontal bar, and a diagonal bar by means of pin joints. Component pin engagement. [0006] The uppermost parts of the outer truss and the inner...
