Abstract

PROBLEM TO BE SOLVED: To simplify and reduce size by providing a securing device consisting of a plurality of freely rotatable securing pieces which come out by interlocking with the lift and fall of pallets and support the pallets for each stage of posts of sky parking facilities. SOLUTION: A pallet 6 holding a car or the like is raised by a hoisting motor with a wire, and if a securing piece 62 attached to a pallet 2 touches a first member (securing piece) 81 provided at column side, then the first securing piece 81 turns upward, and permits the passing of the securing piece 62 of the pallet 6. When the securing piece 62 has passed, the rise of the pallet 6 is stopped, and a first securing piece 81 restores by its deadweight and supports the securing piece 62. In this case, the first securing piece 81 will not turn reversely because of the presence of a stopper 85. When lowering a pallet 6, it is slightly raised, the securing piece 62 touches and rotates the second securing piece 82, the first securing piece 81 is rotated upward through a chain 84, and it is sidetracked. By doing this, power equipment for securing becomes unnecessary and the equipment can be simplified.

を果たす。FIG. 3 shows an engaged state of the locking mechanism 8 and the pallet 6 (the locking mechanism provided on the opposite side is constructed symmetrically). In this case, a locking piece 62 is provided at the end portion 61 on the side surface of the pallet 6, and this is engaged with the first member 81 of the locking mechanism 8 to lock and hold the pallet 6 at that position. The first member 81 is pivotally supported by the shaft 81 ′ and is rotatable although the rotation angle is limited, and the second member 82 is located slightly above the first member 81 and pivots on the shaft 82 ′. It is supported, and it is also rotatable with a limited rotation angle. The shaft 81 and the shaft 82 ′ have a small diameter gear 8 on both shafts so as to rotate in conjunction with each other.
1 "and a large diameter gear 82" are fixedly installed, and a belt chain 84 is installed between both gears. Therefore the first
If the member 81 is slightly larger, the angle of rotation with the second member 82 is different, but the members 81 rotate in conjunction with each other. In addition, a third member 83 is fixedly mounted on the shaft 81 ′ together with the first member 81. The third member 83 is fixed to the housing as the locking mechanism 8 and is partially housed in the intermediate beam member 5 of the structure. It is provided. That is, the first, second,
The third member rotates in conjunction with each other, and a part of the member or the like projects and retreats in the ascending / descending region of the end portion 61 of the pallet 6 to perform their respective functions.

することができる。FIG. 4 is an explanatory view showing the operation process of the locking device of the present invention. With this drawing, the locking mechanism 8 and the pallet 6 are shown.
The engagement and disengagement of the pallet 6 will be described in chronological order. The pallet 6 is lifted by the hoisting motor 71 via the hoisting wire 71, and the locking pieces 62 provided at both end portions of the pallet 6 are projected in the hoisting region. Approaching the tip of the member 81 <(A) in FIG. 4>, making contact and pushing and rotating the member <(B) in FIG. 4>, beyond which the pallet 6 stops (pallet). Although a series of operations of No. 6 are omitted in the drawing, each operation is controlled by reversing the limit switch provided locally). At this time, the first member 81 is pushed up and rotated by the locking piece 62, but since the rotation angle for overcoming this is not large (the center of gravity is still on the left side of the shaft in the figure), the stopper 85 is moved by its own weight. Return to the original position with. Then pallet 6
Is slightly lowered and the tip of the first member 81 and the locking piece 62 are engaged with each other, so that the pallet 6 can be locked and held in a predetermined space in the state shown in FIG.

のである。Next, the releasing and lowering of the locking and holding of the pallet 6 will be described with reference to FIGS. 4 (C) and 4 (D).
The pallet 6 is slightly raised and the locking piece 62 is moved to the second member 8
Contact the tip of No. 2 and push up the member a little and rotate it to stop. At this time, gear 81 "that works with gear 82"
Is rotated further to retract the tip of the first member 81 from the ascending / descending region of the pallet 6, and at the same time, the third member 83 fixed integrally with the same member alternates in the ascending / descending region. The tip protrudes. Subsequently, the pallet 6 reverses and begins to descend, but since the first member 81 largely rotates as described above and the center of gravity of its own weight is located on the right side of the axis in the figure,
Even if the locking piece 62 is separated from the second member 82, the locking piece 62 is kept in the retracted state by its own weight, and its passage is allowed without any contact with the falling locking piece 62. Further, the pallet 6 descends, the locking piece 62 contacts the tip of the third member 83, and pushes down and rotates this. At this time, the first member 81, which is coaxial with the third member 83, projects again into the elevation region of the pallet 6,
At the same time, the tip of the third member 83 is retreated and alternates. In addition, the second which is interlocked with the above operation via the chain belt 84
Member 82 returns to its original position and returns to the original state. The pallet 6 (6) of this multi-storey car park repeats the series of operations described above to store the vehicle in the upper stage and to leave the vehicle, and this also functions similarly when it is adopted in an article warehouse. .

効利用がなされるなどの効果をもたらすものである。When a pallet locking device uses a power device such as a power cylinder to drive the locking mechanism, sufficient maintenance of related devices and members required for the power is essential.
Therefore, this locking mechanism is installed on the front and rear structures of the pallet so that maintenance and inspection from the outside can be facilitated. Therefore, the locking and holding of the pallet in the front and back, that is, in the longitudinal direction is unavoidable. Since such a pallet is provided with locking margins before and after the pallet, the pallet becomes longer and the deflection near the longitudinal center is large.
Since it is necessary to make the entire pallet sturdy, the weight of the pallet itself must be increased. Since the pallet locking mechanism of the present invention eliminates the power unit and has a small bulk,
Maintenance is almost unnecessary and it can be installed in the inner part of the structure, which allows the pallet to be locked and held at both ends, and thus this short width-wise holding is possible. In the comparative test (experimental value by the applicant), the result that the same vehicle can be loaded and the weight of about 2/3 of the pallet weight can be produced is obtained. Further, the locking mechanism is housed within the width of the pillars of the compact structure and the non-structured structure, and the effect that the frontage of the entire facility is effectively utilized due to the narrow space in the frontage direction.
