Description

Vehicle fall prevention device of parking facility

The present invention relates to a device for preventing a vehicle fall of a parking facility, and more particularly, to prevent a vehicle waiting on an elevation surface of a mechanical parking facility from rushing and falling due to sudden acceleration or operation mistake, thereby preventing damage to a parking facility and a vehicle or human casualties.

In general, parking facilities such as buildings are provided with a plurality of parking storage compartments, and a bogie moving space in which a vehicle is mounted is disposed between one or both storage compartments.

A bogie for loading and storing vehicles is installed on each floor, and a lift for transporting vehicles vertically between each floor and the entry surface is installed on one side of the parking compartment.

For example, in the case of a flat reciprocating parking system, the process of putting a vehicle in is as follows.

When the cage door is opened by pressing a button on the control panel (not shown), and the car placed on the cage in standby is parked through the open door, the cage moves to the designated floor and stops on the carriage unit, and then the pallet placed on the cage is transported to the traveling carriage.

Next, the traveling cart again travels and stops in the designated storage room to store the pallet.

In addition, after the pallet was transferred to the storage room, the empty pallet was put on the bogie again and transferred to the cage, and the cage on which the empty pallet was placed rose to the elevation surface and stopped in a standby state.

On the other hand, when the vehicle is shipped out, it proceeds in the reverse order of the time of warehousing as described above, and a device for transferring the pallet from the storage room to the bogie position is provided in the cart.

As a device for transferring the pallet from the storage room to the bogie position, a moving pallet for transporting the vehicle from the cage to the storage room and a fraction roller device for driving the pallet are provided to load or leave the vehicle.

A vehicle waiting for warehousing is located on the entrance surface of the parking facility, and when a gate that is mainly raised and lowered is opened, it enters the elevating cage, is loaded, and then warehousing is performed.

Conventionally, the gate installed on the entrance surface is used to maintain only the shape of a door that is lifted only when the vehicle is released from the cage or in a state where the vehicle can enter the parking facility, so its structure is simple and rigidity against the impact of the vehicle cannot be sufficiently secured

However, unexpected abnormal situations, such as sudden acceleration of the vehicle or operation mistakes, or a case where a driver waiting at the entrance of the elevator misunderstands that the elevator gate is open and moves the vehicle forward often occur.

In this way, when the vehicle proceeds toward the parking facility in a state where the elevator gate is not opened, an accident occurs in which the vehicle enters through the weak gate and falls, and the vehicle and the parking facility are greatly damaged.

In addition, there was a problem such as the loss of life to a driver riding in the vehicle.

Conventionally, Korean Patent Registration No. 10-1214466 has proposed a technique of separately installing an elevating safety fence in the form of a crossbar on the door to prevent the above problem.

Therefore, when such a vehicle is impacted, the safety fence part buffers the impact of the vehicle at the front or rear of the door, so the fall of the vehicle can be prevented, but the safety fence part has to be installed separately from the door.

Domestic Patent Registration No. 10-1214466 (registration date: December 14, 2012)

The present invention has been made to solve the above-mentioned problems, and even when the vehicle is rushed due to sudden acceleration or operation mistake linked to the inside of the gate installed on the entrance surface, it is possible to prevent the case of falling into the parking facility. It is to provide a vehicle fall prevention device.

Another object of the present invention is to provide a vehicle fall prevention device capable of preventing severe damage to a vehicle and a parking facility when the vehicle is greatly damaged.

In order to perform a characteristic function to achieve the object of the present invention as described above, the characteristics of the present invention are as follows.

A vehicle fall prevention device according to an embodiment of the present invention is a parking facility for loading and unloading by loading a vehicle into a cage (3) inside a gate (2) that is opened and closed vertically for vehicle entry and exit on a boarding surface (1),

A fixing frame body 10 fixedly installed between the gate 2 and the cage 3 on the upper surface of the riding surface 1 and having an open top;

A pair of shafts 20 rotatably installed to the fixed frame body 10 while maintaining a distance therebetween;

A pair of stoppers 30 respectively axially coupled to the shafts 20;

Drive gears 40 and 41 that are axially coupled to one side of the stopper 30 to the shaft 20 and geared to each other in a meshed state;

A pinion 50 geared to either one of the drive gears 40 and 41;

It is characterized in that it is configured to include a forward and reverse motor 60 that transmits rotational force to the pinion 50 so that the pair of left and right stoppers 30 rotate simultaneously when the gate 2 is opened and closed.

A rotation lever 70 having a slot 71 attached to the outside of the fixed frame body 10 is coupled to the shaft 20, and the movement range is controlled by blocking the rotation of the forward and reverse motor 60 by the proximity sensors S1 and S2 installed at positions where the stoppers 30 are rotated in horizontal and vertical directions with respect to the ground.

The rotation lever 70 and the shaft 20 are fixed in position with a bolt 72.

According to the present invention, a stopper interlocked with the gate is rotatably installed between the gate and the cage in a state in which the vehicle is waiting on the entrance surface for parking by driving the forward and reverse motor.

Therefore, in a state in which the gate is lowered and the entrance of the parking facility is closed, the stopper maintains a state raised perpendicular to the ground, so that the vehicle damages the gate and rushes unintentionally due to sudden acceleration or careless operation. By preventing a fall, damage to the vehicle or breakdown of the parking facility can be prevented.

In addition, it is possible to prevent serious personal injury to occupants, thereby significantly improving the reliability and safety of the parking system.

Effects of the present invention are not limited to those described above, and other effects not mentioned will be clearly recognized by those skilled in the art from the description below.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In general, parking facilities such as buildings are provided with a plurality of parking storage compartments, and a truck moving space in which a vehicle is mounted is disposed between one or both storage compartments.

A bogie for loading and storing vehicles is installed on each floor, and a lift cage for vertically transporting vehicles between each floor and the entry surface is installed on one side of the parking compartment.

When a control panel is provided at the entrance of the parking facility, the gate is opened by pressing a button for warehousing, and the car loaded on the cage in the waiting state is loaded, the cage is moved to the designated floor and warehousing is performed.

In addition, at the time of leaving the car, it proceeds in the reverse order at the time of warehousing as described above.

The fall prevention device of the present invention is characterized in that it is possible to prevent the case where the vehicle waiting on the entrance surface rushes and falls for reasons such as sudden acceleration or operation mistake, thereby preventing damage to parking facilities and vehicles or human casualties.

First, the frame body 10 is firmly fixed to one side of the gate 2 installed on the entry surface 1, that is, to the inside of the parking facility in which the cage 3 moves up and down.

The fixed frame body 10 has a square frame shape with an open top so that the stopper 30 can be rotated, and its height is located in the center between both tires in consideration of the extent to which it does not come into contact with the bottom surface of the vehicle body entering. (FIGS. 1 and 2)

And, the stopper 30 axially coupled to the shafts 20 while maintaining a spaced distance is set to a length that does not contact the tire even when positioned horizontally so as to contact the riding surface 1.

A pair of shafts 20 are rotatably installed by bearings 11 on the fixed frame body 10 while maintaining a spaced distance from each other, and a pair of stoppers 30 are axially coupled to the shafts 20 through a key to rotate together.

In addition, drive gears 40 and 41 are axially coupled to one side of the stopper 30 to the shaft 20 in a state of meshing with each other, and to the drive gear 41 on one side of the drive gears 40 and 41, the pinion 50 coupled to the shaft portion of the forward and reverse motor 60 is geared (FIGS. 5 and 6).

The forward/reverse motor 60 transmits rotational force to the pinion 50. An electric circuit is configured so that the gate 2 rotates simultaneously when the gate 2 is opened and closed for the entry and exit of the vehicle. The left and right pair of stoppers 30 coupled to the drive gears 40 and 41 through the shaft 20 are rotated vertically or horizontally from the entry surface at the same time.

Here, the shaft 20 is coupled with a rotation lever 70 to which a slot 71 is attached to the outside of the fixed frame body 10, and the stoppers 30 are rotated in horizontal and vertical directions with the ground. Proximity sensors S1 and S2 are installed, respectively.

The proximity sensors S1 and S2 are installed at an angle of about 90 degrees from the center of the shaft 20, so that when the shaft 20 is rotated by driving the forward and reverse motor 60, the rotational movement angle is controlled vertically and horizontally in the range of about 90 degrees.

The rotation lever 70 and the shaft 20 are firmly fixed with bolts 72 and rotated together. For example, when the slot 71 is detected by the proximity sensor S2 located at the bottom, the downward rotation operation of the stopper 30 is stopped, and at this time, the gate 2 is opened and the vehicle enters and exits.

And, when the vehicle entry/exit is completed, an electric signal is applied to the forward/reverse motor 60 again at the moment when the gate 2 is lowered, and the rotational force is transmitted by the pinion 50 and the drive gears 40 and 41, so that the stoppers 30 rotate approximately perpendicular to the entrance surface 1, and when the slot 71 is detected at the position of the upper proximity sensor S1, the rotational operation of the stopper 30 stops while maintaining the vehicle fall prevention state. 1 and Figure 3)

In this way, the stoppers 30 are installed vertically at a certain height inside the gate 2, so that the stoppers 30 are blocked when entering the inside of the parking facility while damaging the gate 2 due to abnormal operation of the vehicle. It is possible to prevent a fall.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope of the technical spirit of the present invention. It will be clear to those skilled in the art.
