Abstract

PURPOSE: Pairs of elevators are provided to have better transmission ability per unit area than an escalator, to decrease an installation space and the consumption of electricity, to save installation cost and to improve safety. CONSTITUTION: Power of a motor from a power motor(20) is transmitted to a chain connected to a rope through a decelerator. Then, a middle rotary shaft is hung with plural folds of heavy steel wheels are hung and is rotated to have inertia through a fly wheel(29). Accordingly, the free fall acceleration force by the force of a spring and gravity is naturally divided so that the movement upon start and stop becomes soft. In addition, it passes through a pulley(21) and connected to a frame chassis unit for covering an elevator BOX. In the meantime, a brake device(34) for keeping position energy controls the movement of the elevator by holding the rope on stopping.

Description

A pair of elevators

The present invention relates to an elevator that applies the principle of the law of conservation of energy dynamics, such as the reason that the pendulum reciprocates, and connects several elevator boxes up and down, and the vertically connected elevator box groups [Flock] are on both sides. By symmetrical with each other arranged as shown in Fig. 1 to balance, the frame doors to form a pair of the whole to give out the door to pass in all directions, forming a skeleton chassis,

The upper and lower sides of the elevator box group symmetrically connected to each other in a row as shown in the drawing [Fig. 7], and between the power transmission unit using a fry wheel [29], and a pair of elevators at the bottom of the spring [Fig. 9]. A load offsetting portion [40] which induces a reciprocating motion of the pendulum so that almost all of the load of the rod is supported;

Floor height adjusting device portion between the elevator box group, that is, the floor height adjustment control device [Fig. 10] between the upper and lower elevator boxes,

It consists of an automatic control system [FIG. 7] management unit that handles all operations such as start and stop, opening and closing of doors, and a brake control unit [FIG. 7] and [FIG. 8] for preserving potential energy.

The left and right elevator BOX group moves up and down in the opposite direction by one floor or two floors [Fig. 3], and is a mechanical equipment device for stopping side by side facing each other, and is mainly used for short-distance mass transportation at the lower floor of a building. It is about a pair of elevators.

The conjugator mainly repeats the ups and downs continuously and repeatedly within several floors of the lower floors of the building, allowing passengers to move with each other as shown in FIG. Its properties make it suitable for short-distance mass transport in low-rise parts.

An escalator is a mechanical technology that is used for short-distance mass transportation within existing lower floors of buildings.

Escalators take up a lot of area to install first and are difficult to apply without a large building. In addition, because the installation cost is excessive, there are many economic difficulties.

And even after installation, power consumption is too high, and the operation is suspended during off hours during the rush hour.

In addition, frequent safety accidents injure passengers.

For example, an escalator puts your foot on a moving scaffold when you get on and off, often with your feet between the stairs and the stairs. There is a danger of stepping on your feet. In some cases, the head is incorrectly pushed out of the moving guide rail, and the head is hit by the stairs on the other side of the rail, causing head injury.

In addition, there are many safety problems, such as moving between stairs and fixed railing walls, women's heels wearing high heels, and accidents involving long coats of clothing. And the escalator has an ascending and descending entrance far away from the opposite position, and when the customer changes his mind about going up, or when he goes down to find the entrance to go down, the stairs to go up appear again. There is inconvenience.

The present invention aims to solve the above problems, and in particular, compared to an escalator, it has a larger transportation capacity per unit area, but has a comparative advantage in the small footprint and low installation cost, and a small amount of power consumption and safety, etc. Is to provide a pair of lifters.

In order to achieve this object, the conjugate according to the present invention,

It relates to an elevator that applies the principle of the law of conservation of energy dynamics, such as the reason that a pendulum reciprocates. It connects several elevator boxes up and down, and the vertically connected elevator box groups [groups] are symmetrically to the side. By arranging as shown in [Fig. 1] to achieve a balance, the frame door to form a pair of the entire frame by giving out the doors so that they can pass in all directions,

And it consists of a brake control unit [Fig. 7] and [Fig. 8] for preserving potential energy,

The left and right elevator BOX group moves up and down in the opposite direction by one floor or two floors [Fig. 3], and is a mechanical equipment device for stopping side by side facing each other, and is mainly used for short-distance mass transportation at the lower floor of a building. It is characterized by.

Hereinafter, with reference to the accompanying drawings will be described the operation principle and operation of the conjugate of the present invention.

First, in [Figure 2], the state before the movement of the conjugate is further down the [a] part of the left side. [A] Part 2F has A and 1F C rides, and part [B] has B riding 2F. A, B and C moved to elevator BOX opposite each other.

After a while, after moving the elevator, the [I] part of the right side is further down.

As a result of the movement, [A] is riding B on part 3F, and [B] is riding A on B and C on B1. They moved from one layer to another at the same time.

In the next [FIG. 3A], the left part of the state before the movement of the conjugate is further down. A on the left side 1F and B on the B1, respectively, C on the 1F on the right side.

After a while, the right side is further down after moving the elevator.

As a result, B on the left side 2F, A, 1F, and C on the right side, respectively. [A] is riding B on part 3F, and [B] is riding A on B and C on B1.

After a while, the first part of the pair's move is again in the left part.

A moved down from 2F, B moved from B1 to 2F, and D moved from 1F to B1.

After a while, the right side is further down after the second movement of the conjugate.

B got off at 2F, D got off at B1, and F moved from 2F to 1F.

In the next [Fig. 3b], the left part of the state before the movement of the conjugate is further down.

In the same way, A is from 1F to 4F after the 2nd move, B from 1 to 2F after the 1st move, C from 1F to B1 after the 1st move, and D is 2F to 1F after the 2nd move. F moves from 4F to 1F after the 2nd move, and K moves from 2F to 1F after the 1st move.

This time, the principle and operation of the multi-pair elevator (Mulki Elevator), which has a more complicated structure by applying the conjugate, will be explained.

First, FIG. 5A illustrates a dual structure of a multi-paired elevator (multi-elevator) in which a pair of elevators 'Ga' and 'I' and a pair of elevators 'D' and 'Dar' are arranged in duplicate. Top view.

Figure 5b is a cross-sectional view of the operation of the multi-pair elevator (multi-lever) showing that many people can move several floors at the same time in the first movement.

See the three-dimensional drawings on the right for easy understanding.

FIG. 6A is a diagram of a multi-pair elevator (multi-elevator) showing an example of a function in which 40 elevators are connected to ten floors and are repeatedly operated in double pairs. In the enlarged view of FIG. 6D, (a) and (b), Ra is an unfolded plane.

Then, the figure before the movement of the conjugate in Figure 6a is further down the left part.

As the figure shows, A is 1F to 10F after the 2nd move, B is 1F to B2 after the 1st move, C is 1F to 6F after the 2nd move, and D is 1F after the 1st move. In B3, F moved from 1OF to 1F after the 2nd movement.

Referring to FIG. 7 again, the mechanical operation, structure, and physical operation principle of the conjugate elevator [pair elevator] will be described in detail.

The conjugate of FIG. 7 is composed of three floors, and the applied building has different heights of B1, 1F, and 2F, and 2F and 3F have the same height.

The rope power transmission process of this pair of elevators,

From the power motor [20] to the chain through the reduction gear for transmitting the power of the motor of [28] to the chain, it is transmitted to the chain [Fig. 8] connected to the rope. The heavy rotation wheels are attached to the intermediate rotation axis to rotate them so that they have inertia through the flywheel [20], thereby naturally distributing the free fall acceleration force due to the spring force and gravity to smooth the movement during start and stop operation. Guided by the pulley [21], it is connected to the skeleton chassis surrounding the elevator box group.

In the meantime, the brake braking device 24, which holds the rope when it stops and conserves potential energy, controls the operation of the elevator.

On the other hand, the height of the elevator box does not coincide with the floor due to the difference in the height when the elevator stops in [7], the floor height adjustment control unit 30 to correct the error will be described.

Figure 10a is a view explaining the principle of the floor height adjustment device to adjust the difference when the floor height is different for each floor when the foot elevator [pair].

If the height of each floor is different when the elevator [pair] is stopped [Fig. 10b] can be applied as a floor height adjustment device to adjust the height so that the elevator box of the upper and lower two floors all move in the same direction. If the floor height is different for each floor [Fig. 10c] when the elevator is stopped [Fig. 10c] can be applied to the floor height control device for adjusting the height so that the elevator box of the upper and lower two floors move in opposite directions.

And there is no floor height adjustment device between the upper and the middle of the elevator BOX of [Fig. 7], because the floor heights of 2F and 3F are the same.

Finally, a spring (Fig. 9) acting as a reaction force at the bottom to cancel the load of the elevator (pair) will be described.

This is the same as the pendulum reciprocating [48], applying the principle of the law of conservation of energy mechanics.

When all the loads acting on the left side of the upper pair elevators are applied, one can see the shape of the left spring group 41 which is constricted in the balance of the forces. At this time, the brake braking device 24 holds the rope in the upper part of the right foot elevator.

In addition, when all the loads acting on the left side of the upper pair elevator [lifter] are applied, the shape of the right spring group 42 relaxed by the balance of the force can be seen. At this time, the brake braking device 24 holds the rope in the upper right foot elevator.

Here, the brake braking device 24 serves to maintain the potential energy of the right foot elevator.

By the way, there is an imaginary line 45 showing the neutral position at the moment when [41] and [42] are at the same position.

What if the brake brakes [24] let go of the ropes?

Here, the law of conservation of energy dynamics will be explained with reference to the reciprocating motion of the pendulum [48].

The pendulum stops at both ends and has maximum velocity in the center.

Similarly, the conjugates are stopped at the positions [41] and [42], where the potential energy is maximum and the kinetic energy is zero. In addition, at the position of the imaginary line of [45], the conjugate moves at the fastest speed, and the potential energy is zero at the maximum.

Due to the reaction of the spring, the weight of the elevator is almost zero, so that the elevator enters into the natural law of motion like the reciprocating motion of the pendulum and is driven by the restoring force to return itself to the neutral position [45]. The power consumption of the load on the motor is only marginal, making up for the loss of passengers and other friction.

As described above, according to the conjugate of the present invention

The transport capacity of the conjugate is about two-thirds that of the escalator,

The occupancy area is less than half, and the installation cost is about 2/5.

Therefore, even if two sets of conjugates are installed,

It is more economical than the cost and area of installing one set of escalator.

The transport capacity is increased 1.2 times.

And power consumption is less than 1/5.

As a result, the advantage of large transport capacity at low cost, small area, and low power increases the utilization of large-scale transport in the lower part of the elevator.

Most buildings want smooth copper lines [upstairs] between the upper and lower floors [underground floor-1st floor, 2nd floor] of the lower floor, but this makes it a burden to install an escalator. This is because escalators occupy a large area and require excessive installation and maintenance costs.

In that sense, the applicability of conjugates is enormous.

For example, it can be easily installed from the basement floor to the second-floor banquet hall in the lobby of the hotel's lower floor, and it can be applied to the lower floor neighborhood living facilities of the multi-purpose building.

Passengers are used on each floor at the same time, so that many people can be transported simultaneously.

In addition, compared to elevators, passengers can spend less time waiting for elevators. The waiting time of the conjugator is only a further travel time [5 to 8 seconds].

In a row, even if 50 people flock together, 25 people can ride first, and the remaining 25 people can board in 5 to 8 seconds. If the directions are different, 25 people can go both ways at once.

It is effective to maximize the space utilization of the structure because the elevator is used at the same time by filling the elevator aisle.

And elevators need to add balance, but in elevators they also do not need counterweights.

The effect of eliminating the inconvenience of the escalator will be described again.

The escalator's up and down entrances are far away from each other on the opposite side, so when customers change their minds when they try to go up, or when they go to the entrance to go down, when the stairs appear, they have to go back again. .

The pair of elevators are all over the place, and if you move one step, you can go up or down as you like.

The escalator puts your foot on the footrest when you get on and off, often with your feet between the steps. In addition, accidents often occur when the wrong head is pushed out of a moving guide rail that rises and hits the head on the stairs across.

In addition, there are many safety problems, such as accidents in which shoes are caught by moving stairs and fixed railing walls, and accidents in which cloth is caught.

The elevator is safer than a normal elevator. Especially well balanced on both sides, there is no risk of falling even when power is lost.

In particular, in the case of department stores, the entire floor is installed as an escalator. When the escalator is replaced by a pair of elevators, construction is possible with a smaller area and a lower price, and as a result, the rental area can be increased.

And since doors are opened and closed at the same time in all directions, free handling of pedestrian traffic is possible.

In addition, it is possible to contribute to the design of free and refined space composition because it enables interesting space composition from various angles in architectural design.
