Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in a vertical circulation type parking facility in which vehicles are stored by moving a large number of vehicle loading cages in a vertical direction.

(Prior Art) The above-mentioned vertical circulation type parking equipment generally has a large number of vehicles connected via hanging members 2 to two endless chains 1 in the front and back that circulate in the vertical direction, as partially shown in FIG. The loading cages 3 are suspended in a chain, and a vehicle entry area 4 is set at the lowest part of the lower turning section, and an entrance/exit 6 is opened on the above-ground wall of the building 5 facing the vehicle entry area 4. has been done. Each cage 3 pivotally supports side guide rollers 7, 7 on the left and right sides of the chassis 3a, and upper guide rollers 8a, 8 on the upper left and right of the rear cage frame 3b.
It supports b. In addition, inner and outer guide rails 9 and 10 are provided along the left and right vertical movement paths of the third cage group.
In the upper and lower rotation parts, arc-shaped rotation guide rails 11a and 11b (only the rotation guide rail of the lower rotation part is shown) are installed separately on the left and right sides, respectively, as cage rotation guide means. There is.

Therefore, as the endless chain 1 circulates, the cages 3 move in circulation, and when each cage 3 moves up and down along the left and right vertical movement paths, the left and right side guide rollers 7, 7 move inside. - Engages with the outer guide rails 9 and 10 to provide guidance when going up and down. Now, it is assumed that the desired cage 3 is moved circularly in the clockwise direction in FIG. The upper guide roller 8b on the right side is fitted into the guide groove _11b1 of the swing guide rail 11b on the right side, and the side guide rollers 7, 7 are separated from the inner and outer guide rails 9, 10. In this way, the cage 3 descends while being rotationally guided by the right rotation guide rail 11b, and just before reaching the bottom, the left upper guide roller 8a moves to the left rotation guide rail 11b.
It fits into the guide groove _11a1 of a. When the cage 3 reaches the bottom and stops, the left and right upper guide rollers 8a and 8b are supported in a state where they are fitted into the lower end openings of the guide grooves 11a ₁ and 11b ₁ , respectively.

(Problems to be Solved by the Invention) The above-mentioned swing guide rails 11a and 11b, which have been conventionally and generally used, are formed by curving a channel material having a U-shaped cross section, and are fixed to the frame of the building 5. The inner width B of the guide grooves 11a ₁ and 11b ₁ is slightly wider than the diameter d of the upper guide rollers 8a and 8b in order to allow the upper guide rollers 8a and 8b to pass through them smoothly. Therefore, when the cage 3 reaches the bottom and stops as described above, due to the large inertia of the cage 3 and the mounted vehicle W, the upper guide rollers 8a and 8b move to the lower ends of the guide grooves 11a ₁ and 11b ₁ . The cage 3 bounces when it is fitted into the opening, causing the entire cage 3 to vibrate and generate large noise.

(Means for solving the problem) In the present invention, the cage rotation guide means of the lower rotation section is provided with a pair of guide plates that are vertically spaced apart and form guide grooves, and at least one of the guide plates is made swingable. It is attached by an actuating cylinder.

(Function) Prior to the start of circulating movement of the cage group, the width of the guide groove is maintained wide enough to allow the smooth passage of guided tools (for example, guide rollers) attached to the left and right sides of the upper part of the cage frame of each cage. , at the same time as the circulating movement of the cage group is stopped, the at least one guide plate is swung in a direction toward the other guide plate by actuation of the actuating cylinder to narrow the width of the guide groove, and the cage is stopped at the lower turning portion. The guided tool is pressed between both guide plates to prevent the cage from steadying.

(Example) The example shown in FIGS. 1 to 4 will be described. For convenience of explanation, the left and right in Figures 1, 3, and 4 are referred to as "left" and "right," and the right and left in Figure 2 are referred to as "front."
