Description

Multi-speed Speed Escalator

The present invention relates to a multi-stage speed escalator, and more particularly, to a multi-stage speed escalator that can control the operating speed of the escalator in multiple stages to prevent unnecessary power consumption, thereby extending the mechanical life and reducing energy consumption. will be.

In general, an escalator is widely used as a vertical transporter together with an elevator, and the escalator is a device for continuous mass transportation in a certain direction, and is characterized by being able to ride without waiting.

In the early days, commercial facilities such as department stores were the center of demand, but with the development of subways and the solidification of stations, the demand for public transportation increased, and now it is spread to a wide range of fields such as art museums, theaters, amusement parks and amusement facilities. It came to be.

The speed and inclination angle of the escalator are specified to be 30m or less and 30 ° or less each minute. Therefore, the standard escalator has an inclination angle of 30 ° and a speed of 30m per minute so as to be most efficient within the prescribed range.

FIG. 1 is a block diagram of a general escalator, and as shown in FIG. 1, power generated through the driver 1 is transmitted to the upper sprocket 2 and the lower sprocket 3 through the step chain 4. It comprises a step (5) fixed to the step shaft of the step chain (4) and a driving device for driving the handrail (6) by the power transmitted from the upper sprocket (2). 6) The passengers move as standing in the step (5), and the upper and lower landings that the passengers ride on are called the upper and lower upper plates, respectively.

At this time, in the conventional escalator structure as described above, when the passenger travels on the escalator at a speed of 30 m / min or when there are no passengers, the escalator automatically stops and stops the operation, so the frequency of ON / OFF There is a problem that the mechanical life is high, so many shorten the life is shortened, the power consumption is increased.

The present invention was devised to solve the above problems, and the object of the present invention is to control the driving speed in multiple stages according to the passenger's boarding status to prevent unnecessary power consumption, increase the mechanical life, and reduce the energy consumption. To provide a multi-speed escalator that can be made.

In order to achieve the above object, the power generated through the driver is transmitted to the upper sprocket and the lower sprocket through the step chain, and the hand is driven by the power transmitted from the step and the upper sprocket fixed to the step shaft of the step chain. It is composed of a driving device for driving the rails and the passengers move as the passengers stand on the step in the state where the step and the handrail are moved, and the escalator including the upper and lower upper boards, which are the upper and lower platforms, which the passengers ride on and off. In the above, the first and second sensing sensors for binding the entrance and exit of the passengers on the upper and lower ends of the rectangular upper and lower ends, respectively, and the left and right end spaced apart from the landing plate of the upper upper plate and a predetermined distance, respectively Installed on one side of the upper comb plate of the upper and lower upper plates A second sensor for installation with a multi-speed type escalator respectively to detect the boarding of a passenger are provided.

Hereinafter, with reference to the accompanying drawings an embodiment of a multi-stage speed escalator according to the present invention will be described in detail.

Figure 2 is a perspective view showing a multi-stage speed escalator according to the present invention, Figure 3 is a flow chart for explaining the operation of the multi-stage speed escalator according to the present invention, Figure 4 shows a speed curve of the multi-stage speed escalator according to the present invention As a graph, the multi-stage speed escalator according to the present invention transmits the power generated by the driver to the upper sprocket and the lower sprocket through the step chain, and to the power transmitted from the step fixed to the step shaft of the step chain and the upper sprocket. It is composed of a driving device for driving the handrail by the passengers to move as the standing state in the step in the step and the handrail is moved, and comprises a top and bottom platform that is the upper and lower platform for the passengers ride down In the escalator, the phase Square pillars 70 are attached to the landing plates 52 and 62 of the upper plate 50 and the lower plate 60, respectively, and spaced apart from each other by a predetermined distance, and the passengers are placed on the upper and lower ends of the inner surface of the square column 70. The first detection sensor 72 is installed to detect the entry and exit of each, and detects the occupant of the passenger on one side of the upper plate (54) 64 of the upper upper plate 50 and the lower upper plate (60) The second detection sensor 82 is installed respectively.

It describes the operation of the present invention configured as described above.

As shown in Figures 2 to 4, ① the escalator is in a stopped state in the initial state, ② passengers separated by a predetermined distance from the landing plate 52, 62 of the upper upper plate 50 and lower upper plate 60. At the moment of passing through the rectangular pillar 70, which is bound at both ends of the left and right ends, the escalator is in response to the deceleration of the above-described driver by detecting the first detection sensor 72 installed on the upper and lower ends of the inner side of the square pillar 70. The vehicle starts to travel at a speed of 15 m / min, and a passenger passes through the second detection sensor 82 installed at one side of the upper comb 54 and 64 of the upper upper plate 50 and the lower upper plate 60, respectively. At the moment, the escalator operates normally at a speed of 30 m / min in response to the acceleration of the driver by the detection of the second detection sensor 82.

At this time, assuming that the time setting is set to 2 minutes when the first detection sensor 72 is operated, and that the time setting is set to 1 minute when the second detection sensor 82 is operated, e. Afterwards, if there is no passenger on board after one minute, the escalator will automatically run at 15m / min. If there is no passenger on board, the escalator will stop automatically.

At this time, if the passenger boarded 2 minutes before the automatic low speed operation at the speed of 30m / min → 15m / min elapsed, the escalator will resume normal operation at the speed of 30m / min, and the escalator ① Repeating section ④ will continue the operation.

As described above, according to the multi-stage speed escalator according to the present invention, the operation speed of the escalator is adjusted step by step according to the presence or absence of passengers, thereby reducing the mechanical crowd of the escalator due to unnecessary ON / OFF operation of the escalator, and accordingly It has a useful effect of improving life and reducing unnecessary power consumption.
