Abstract

PURPOSE:To prevent contact between a central protrusive face and a car and to improve the strength of a pallet by providing both the sides of a central protrusive part extending longitudinally with a wheel guide recess part, and protrusively forming a wheel supporting face having a fixed height on the wheel guide recess part through right and left reinforcing groove parts. CONSTITUTION:Inner and outer vertical walls 12, 14 secure the width of a wheel supporting face 21, and improves its strength, and moreover enlarges its modulus of section in cooperation with reinforcing grooves 24, 25. Next the wheel supporting face 21 is increased in its height so as to prevent the occurrence of contact trouble between a central protrusive part 1 and the bottom of a car. Thus a pallet can prevent contact between the central protrusive part 1 and the car, and increase the bending strength, and can be unitedly formed by a press to reduce a rise in manufacturing cost.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical circulation type pallet for a multi-storey parking lot, which is used for mounting a vehicle and carrying it between an elevator device and a parking rack.

[0002]

2. Description of the Related Art In a vertical circulation type multi-storey parking lot, an endless chain is wound between two sets of sprockets which are vertically separated from each other, and a pallet is mounted on each of a plurality of cages suspended between the chains. It is arranged. In the elevator-type multi-storey parking lot, an elevator system for vehicles that moves up and down each parking floor in the building, a carriage that is freely movably arranged in the transport space on each parking floor, and a transport to a parking shelf on the parking floor It has a parking room formed facing the space for use, and a pallet for loading and unloading the vehicle by a transfer device such as a lift of an elevator system for vehicles, a carriage, and a roller conveyor arranged in the parking room. Has been done.

For example, in a conventional pallet used for a vertical circulation type multi-storey parking lot, as shown in FIG. 4, a plate material is bent by press working or the like to form wheel guide concave surface portions 1 on which the left and right wheels are placed on the left and right sides. As a result, the central convex surface portion 3 is formed between the wheel guide concave surface portions 1 via the inner inclined wall portion 2 having a height H of about 80 mm, and the wheel guide concave surface portion 1 is formed.
Reinforcing convex edge portions 5 bent in the lengthwise direction were formed on the inner edge portions of the pallets through the outer inclined wall portions 4 having a height h of about 140 mm to secure the bending strength of the entire pallet.

[0004]

However, in the above structure, the height H of the central convex surface portion 3 is calculated from materials such as the automobile industry, but this condition is that the tire pressure is regulated and unmanned. It is a standard, and there is a possibility that the wheel guide concave surface portion 1 may be recessed due to the load of the vehicle, and the low vehicle height that has been recently desired. At the time of departure or at the time of departure, there was concern that the bottom of the vehicle would rub against the central convex portion 3.

As a countermeasure, it is conceivable to reduce the height H of the central convex surface portion 3, but this cannot be adopted because the section modulus of the pallet becomes small and the bending deformation of the pallet becomes large. Also. It is conceivable to provide a floor plate in the wheel guide concave surface portion 1 of the pallet, which raises the support height of the wheel, but there is a problem in that the weight of the pallet increases and the manufacturing cost increases.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and provide a pallet for a multi-storey parking lot without worrying about contact with the bottom of the vehicle and having sufficient strength.

[0007]

In order to solve the above-mentioned problems, a pallet for a multi-storey parking lot of the present invention has a central convex surface portion extending in the longitudinal direction and wheels provided in the longitudinal direction on both sides of the central convex surface portion. A wheel guide concave surface portion for guiding and supporting, and a reinforcing convex edge portion provided in the lengthwise direction on the outer edge of these wheel guide concave surface portions are a pallet for a three-dimensional parking lot that is integrally formed by bending a plate material, In the center of the wheel guide concave part,
Via the reinforcing groove between the central convex portion and the reinforcing convex edge portion,
The wheel supporting surface is formed by projecting at a predetermined height over the length direction.

[0008]

According to the above structure, since the wheel supporting surface is formed by projecting through the reinforcing groove, it is possible to prevent the accident that the supporting position of the wheel is displaced to the upper position and the vehicle comes into contact with the central convex surface portion. Bending strength can be increased by further increasing the sectional modulus of the pallet, and it can be molded integrally with other components by press working, so there is no increase in weight,
It can be manufactured with a very small increase in cost.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pallet used in a vertical circulation type multi-storey parking lot according to the present invention will be described below with reference to FIGS.

First, the load of a conventional pallet when mounted on a vehicle will be examined, as shown in FIG. Ie A
The cross-hatched part of No. 2 is a place where an extremely large load is applied, and the hatched part of B is a place where a large load is applied. According to this, it can be seen that, except for the supporting portion of the wheel, the load is large on the inner and outer inclined wall portions 2 and 4 as a whole.

Therefore, in the present invention, the inner and outer inclined wall portions of the pallet are formed on the vertical U inner and outer vertical walls 12 and 14, respectively, and the wheel guide concave surface portion 1 is formed on the inner and outer vertical walls 12 and 14.
A wheel supporting surface 21 having a height N lower than the height H of the central convex surface portion 3 is formed by pressing upwards at a constant interval on the inner surface 14 of the wheel supporting surface 21.
23 for reinforcement between the vertical wall 12 and the inner and outer vertical walls 12, 14.
By forming 4 and 25 respectively, the conventional problem is solved.

That is, the inner and outer vertical walls 12 and 14 secure the width of the wheel supporting surface 21 and improve the strength thereof, and, together with the reinforcing groove 24, increase the sectional modulus to secure the strength of the entire pallet, thereby supporting the wheel. To raise the central convex surface 3
Prevents vehicle contact and rubbing accidents. In addition, the number of press working steps is increased, the weight is not increased, and the manufacturing cost is hardly increased.

Further, the wheel mounting surface 21 is formed with a frontward-inclined entrance portion 21a which allows the vehicle to get in and out at a conventional pallet stop setting position, and a vehicle stop member 26 is provided on the rear upper surface. It is fixed. The pallet is supported by suspending its front and rear portions on a suspension frame (not shown) of a cage.

According to the above construction, the wheel guide recess surface of the conventional pallet can be manufactured by pressing the wheel support surface 21 upward, and the wheel support position can be raised to the center of the vehicle. It is possible to prevent a contact accident with the convex surface portion 1, reduce the manufacturing cost, suppress the increase in weight, and increase the strength of the pallet.

[0015]

As described above, according to the present invention, since the wheel supporting surface is formed by projecting through the reinforcing groove, the wheel supporting position is displaced to the upper position and the vehicle comes into contact with the central convex surface portion. In addition to being able to prevent this, the pallet's section modulus can be further increased to increase bending strength, and since it can be integrally molded with other components by press working, there is no increase in weight and no increase in cost. Very few can be manufactured.
