KR100251414B1 - A weight balance of parking machine lifter - Google Patents

Abstract

PURPOSE: A weight balancer of a lift is provided to efficiently park a vehicle by maintaining weight gravity of the lift with a regular state without considering a sort of the vehicle settled on a pallet phase and a pallet approach to the lift. CONSTITUTION: A rail(25) is vertically installed on a lower frame(11) of a lift(10) raising or dropping, and wheels(16,17) travelling on the rail. A weight balancer(12) contains a driving motor(18) rotating the wheel by regulating by a controller. The lift rises or drops up and down by an elevator in a multi-stage typed parking device to draw and park by approaching a pallet(13) including a parked vehicle(14) or an unparked vehicle. The weight balancer mounted on the lower frame of the lift moves to left and right sides of the lift by the driving motor controlled by the controller to locate the weight gravity of the lift in the center of the lift while the pallet enters into the lift.

Description

Weight balance of lift for parking machine

The present invention relates to a weight balance of a lift for a parking machine, and more particularly, to maintain an accurate center of gravity of a lift that can park two vehicles at the same time, thereby providing an improved lift for easy lifting. .

Parking lifts are used in multi-stage parking equipment, and are used to transfer and withdraw pallets in which a car to be parked is placed in the multi-stage parking system. The lift is divided into a type for transporting one pallet and a type for moving two pallets simultaneously.

The lift, which can move two pallets at the same time, allows two pallets to be seated in the longitudinal direction to move the car seated on the pallet into the free space of the multi-stage parking system, allowing more cars to be parked quickly. .

Conventionally, the situation is parked by moving a pallet in which a car is placed without a separate device and means capable of maintaining the center of gravity of such a lift.

If there are only one pallet entering the lift, the center of gravity is not greatly affected. However, in the case of a lift that enters two pallets, a pallet with a car seated on one side of the lift enters an empty pallet on the other side. In this case, the center of gravity of the lift will be in the direction of the pallet.

Of course, since the lift is moved up and down by the elevator, the elevator is in a fixed state by a transportation means such as a wire connecting the elevator and the lift phase, but it contains a risk of accident.

And, since the weight of the car placed on the pallet is different, it is impossible to select and place the same vehicle on two pallets entering the lift.

Tolerance: Light, Light: Small, Light: Medium, Light: Large or vice versa;

Tolerance: Small car, Small car: Medium car, Small car: Large car or vice versa;

Tolerance: Medium car, Medium car: When it is a large car or in the opposite state, the center of gravity of the lift is changed so that the lift may swing when the lift is moving or stops during the moving process. It has a great effect and provides a cause of weakening the durability of the entire parking lot value such as the rapid increase in the fatigue of the lift and the elevator that lifts and lowers it.

Accordingly, in the present invention, in order to solve the above problems, the weight balance is provided on the lower frame of the lift to maintain the center of gravity of the lift in a constant state regardless of the pallet entering the lift and the type of vehicle placed on the pallet. It aims to make parking work efficient.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the present invention for achieving the above object will be described.

1 is a front view of a lift for a parking machine to which the technique of the present invention is applied, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a side view of FIG. 1, FIG. 4 is a perspective view of a weight balance which is an essential part of the present invention, and FIG. It demonstrates together as sectional drawing taken along the A-A line of FIG.

In the present invention, the weight balance 12 is further provided in the lower frame 11 of the lift 10 for moving in and out of the parking lot, the pallet in which the car is placed, while moving up and down by the elevator in the multi-stage parking device. The weight balance 12 moves in the left and right directions (lengthwise) of the lift 10 according to the type of the pallet 13 and the vehicle 14 entering and exiting the lift 10, and thus the center of gravity of the lift 10. This is always located in the center of the lift (10).

The weight balance 12 is formed in a rectangular shape having a thin thickness to have wheels 16 and 17 on both sides, and a drive motor 18 connected to and controlled by a controller (not shown) on the top surface of the weight balance 12. Install).

The chain gear 21 is fixed to the shaft of the drive motor 18 to connect the chain gear 21 and the chain 22 fixed to the shaft 20 for supporting the wheels 16 and 17 by weight balance ( 12, the wheels 16 and 17 slide on the rail 25 installed in the longitudinal direction on the upper surface of the lower frame 11 of the lift 10 and move to the left and right sides of the lift 10 in the longitudinal direction. Keep your balance.

The distance in which the weight balance 12 slides on the rail 25 and moves to the left and right sides in the longitudinal direction of the lift 10 is controlled by the controller (not shown). The drive motor 18 is operated to move the weight balance 12 before the entry is completed and the lift 10 moves.

For example, when a light vehicle enters the left side of the lift 10 and a tolerance on the right side;

Left-light: right-small car, left-light: right-medium car, left-light: right-large car and in the opposite state;

Left-small car: right-tolerance, left-small car: right-medium car, left-small car: right-large car and vice versa;

Left-medium car: right-tolerance, left-medium car: right-large car and vice versa;

Left-Large Car: The pallet 13 enters on the lift 10 by inputting in advance which direction the weight balance 12 should be moved in consideration of the right-tolerance case and the opposite state. It is preferable to immediately grasp the center of gravity by moving the weight balance (12) immediately after the detection.

Looking at the working relationship of the present invention as described above, the lift 10 of the present invention in the multi-stage parking device to lift and lift in the up and down direction by the elevator, while the parked car 14 placed in the parked parking lot 13 The pallet 13 having the car 14 placed therein is taken in and taken out and parked.

In this process, when the pallet 13 enters the lift 10, the drive motor 18, which is further provided on the lower frame 11 of the lift 10, is self-contained and controlled by the controller. By moving to the left, right direction of the lift 10 by adjusting the center of gravity of the lift 10 is always located in the center of the lift (10).

That is, by detecting the difference in the weight (weight including the vehicle) of the pallet 13 entering the lift 10, the weight balance 12 can be adjusted in the opposite direction of the heavy pallet 13 to adjust the center of gravity.

The work such as the weight sensing of the pallet 13 entering the lift 10 includes a load cell capable of measuring the weight on the lift 10 or an electrical sensor capable of recognizing the entry and exit of the pallet 13. Limit switches and the like can be solved by incorporating commonly known technical details, such as linking with a controller.

In the present invention as described above, regardless of the type of vehicle placed on the pallet in the lift to move the two pallets at the same time precisely by adjusting the center of gravity of the lift can perform the parking operation in a stable state, as well as providing the efficiency of the parking operation, It has the effect of improving the durability and quality of parking lot and lift.
