Description

[Detailed explanation of the invention] (Field of industrial application) This invention runs a parent cart carrying a car together with a child car, lifts the car a certain distance with the child car at an empty position, and moves it laterally. This invention relates to a multilevel parking device for parking cars in a room.

(Conventional technology) In a parking system that transports a car to a vacant room using a trolley, moves the car sideways in front of the vacant room, and then parks it in the vacant room, the forks alternately enter each other and move from one fork to the other. A fork type in which the fork is transferred, and a belt conveyor type in which a belt conveyor is inserted into one of the forks to take in the wheels on the fork have been developed.

(Problems to be solved by the invention) In this conventional fork type, the forks must be of a cantilever structure in order to allow the forks to fit into each other, and widening the mounting pitch of the forks may have a negative effect on the tire. In this case, it is necessary to achieve mounting accuracy that allows the fork to smoothly enter any of the many parking positions without interfering with it, which poses problems such as being time-consuming and difficult to adjust.

In addition, with the belt conveyor type, it is difficult to simultaneously take in four tires that do not have equal pressure from the fork, and the belt conveyor may slip, and the belt conveyor has a wider width than the fork type. Because it has to be inserted into the fork, the frontage of the fork must be further widened, and in order to be able to use it for small-diameter tires, etc., the belt conveyor etc. must be downsized, which poses problems in terms of manufacturing and strength. The point was hot.

(Means for Solving the Problems) The present invention has been made in order to solve the problems of the conventional technology. To provide an economical multilevel parking device which can always be normally held and moved laterally regardless of its size, and does not require precise installation.

The gist of this is that a pair of running rails are fixedly installed inside a cage that lifts and lowers electrically and stops at a fixed position, and the cage is moved up and down with a connected running rail and an external running rail that extends outside the cage that runs electrically. A main bogie that stops at a fixed position is provided, and a transverse rail that is orthogonal to the running rail is fixed on the parent bogie, and an electric motor connects the transverse rail that runs on the parent bogie and connects to the external transverse rail that is installed parallel to the outside of the cage. The child car is equipped with a frame that travels sideways and stops at a fixed position, and the child car is equipped with a frame whose upper surface is approximately on the same level as the parent car when it moves up and down a certain distance using cylinders, and the left and right parts that extend and contract back and forth in the direction of travel are provided with cylinders. A pair of slide arms are installed inside the same frame, and when the slide arms are contracted and the frame is lowered, they come into contact with a stopper protruding from the child truck, and the upper surface closes the gap between the parent truck and the frame, forming a passage for the car. At the same time, when the frame is raised and the slide arm is extended, a tire holder is installed at each end of the slide arm, and the tire holder is inserted close to the ground contact surface of the tire of a car placed on the parent truck and locks each tire with the sharpened end. This mechanical multilevel parking system is characterized by being pivotably supported vertically to be rotatable at a fixed angle and having a stopper slightly protruding from the top surface of the slide arm above the tire holder position of the slide arm.

(Function) In the present invention, a parent truck and a child truck are used to travel and traverse, and the child truck is provided with a slide arm and a frame that hold tires and lift the car.

A parent cart on which a car is mounted is raised by a cage to a floor with a designated vacant room, and the traveling rail and the external traveling rail are aligned, and then the parent cart is run to the vacant room. The running rail of the parent truck and the external traversing rail are brought into alignment, the parent truck is stopped, and then the frame with the slide arm inside is raised a certain distance.

At this time, the tire pedestal, which is pivotally supported at the tip of the slide arm, comes off the stopper and rotates downward at a certain angle, aligning the sloped upper surface of the tire pedestal with the slope of the tread near the tire contact surface. Thereafter, the slide arm is extended forward and backward by a cylinder, and is held by pressing outward from the inside under the front and rear tire treads with a tire cradle, and the tire cradle is raised together with the frame a certain distance again to levitate the car.

The cylinder of this slide arm is of a floating type, and the front and rear slide arms are connected to the piston rod and the cylinder, so that the pressure can be applied evenly even when the automobile is at an unspecified stopping position.

After the car floats up, the subcarriage is moved sideways to the external traverse rail, and the frame is then lowered to ground the tires on the floor of the empty room. After the tires are completely in contact with the ground, the slide arm is retracted to park the car and the frame is lowered. is lowered to the initial position, the child car is returned and stored in the parent car, and the parent car is returned to the starting point.

Incidentally, each operation can be automatically performed by sequence control using a limit switch, a photoelectric switch, a proximity switch, etc.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

Figures 1A, 1B and 1C show the sequence of operations when the vehicle is raised in this embodiment.

In the figure, 1 is the parent truck, 2 is the child truck, 3 is the frame,
Reference numeral 4 designates a slide arm installed inside the frame 3, 5 designates a tire pedestal whose upper surface is flat and is pivotally supported at the tip of the slide arm 4, and 6 designates a stopper provided protruding from the child truck 2. Further, 7 is a cage, 8 is a traveling rail fixedly installed in the cage 7, and 9 is a traversing rail fixedly installed on the parent truck 1, and is provided in a direction perpendicular to the traveling rail 8.
