JPH033880A - Ventilating device for inside elevator passage for inclined elevator - Google Patents

Abstract

PURPOSE:To lower the temperature in an elevator passage inside which hot air is confined in summer, by installing a ventilating door which is opened and closed by the output signal supplied from a temperature sensor ad installing a device for forcibly operating a cage when the ventilating door is opened and the cage is put into unmanned state. CONSTITUTION:Ventilating doors 8a and 8b for closing the ventilating ports 7a and 7b installed in an elevator passage 1 are opened when the temperature in the elevator passage 1 becomes over a prescribed value, and when a cage 4 is in unmanned state, forcible operation is carrid out. Since the ventilating doors 8a and 8b are in closed state when the temperature in the elevator pas sage 1 is within a set value, the intrusion of dusts from outside can be suppressed to the min. value, and the contamination in the elevator passage 1 can be reduced. Further, the supply of air into the elevator passage 1 can and the discharge of air from the inside of the elevator passage 1 can be carried out forcibly by the rising/lowering of the cage 4, and the warm air in the eleva tor passage can be speedily discharged outside.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hoistway ventilation system for an inclined elevator having a car that moves within an inclined hoistway.

[Conventional technology]

Recently, as a means of transportation between buildings built on sloped land or buildings built on the upper and lower parts of sloped land, a hoistway is formed along the slope, and a slope equipped with a carriage that goes up and down diagonally within this hoistway has been developed. Row elevators are used. Since this oblique elevator is installed on a sloping ground, in consideration of the scenery, an elevator with a single elevator car and a hoistway provided with transparent glass is mainly put into practical use. However, with this structure, there was a problem that the inside of the hoistway was heated by direct sunlight during the summer, and the inside of the car was also heated.

In order to solve this problem, as shown in Japanese Unexamined Patent Publication No. 59-57877, it has been proposed to provide a ventilation hole in the unit part of the hoistway to let outside air flow into the hoistway. There is.

[Problem to be solved by the invention]

In the conventional technique proposed above, the ventilation opening is always open in the summer.

For this reason, there is a problem in that dust and the like easily enter from the outside and stain the inside of the hoistway.

An object of the present invention is to provide a shaft ventilation system for a diagonal elevator that can reduce contamination in the shaft and more quickly measure the temperature drop in the shaft.

[Means to solve the problem]

The above object is to provide an in-hoistway ventilation system for an inclined elevator, which includes an inclined hoistway, a car movable in the hoistway, and a ventilation vent formed in the hoistway.
a temperature sensor that detects the temperature inside the exit passageway and outputs a signal when the temperature reaches a predetermined temperature; and a temperature sensor that can close the ventilation opening;
and a ventilation foot that opens and closes in response to a signal output from the temperature sensor, and when the ventilation foot is open and the car is unoccupied, the car is forced to close. This is achieved by providing a device to operate the system.

[Function] The ventilation legs installed in the hoistway that block the i-+ rail ventilation openings are designed to open when the temperature in the hoistway reaches a specified level or higher, and when the car is unattended. If there is, it will be forced to drive. In the past, since the ventilation legs were closed at a predetermined temperature within the hoistway, the intrusion of dust and the like from the outside was kept to a necessary minimum, making it possible to reduce contamination within the hoistway. In addition, by forcing the car to operate, air is forced into the hoistway and exhausted from the hoistway by raising and lowering the car, and the warm air in the hoistway is quickly expelled to the outside. Can be discharged.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Figures 1 and 2 are explanatory diagrams of a diagonal elevator equipped with a hoistway ventilation system according to an embodiment of the present invention. Figure 1 is an overall side view, and Figure 2 is a drive circuit diagram of a ventilation door. It is.

In the figure, ] indicates a hoistway, and a machine room 2 equipped with a hoisting machine 3 is provided above the hoistway 1 . 4 is a car, and 5 is a counterway 1-, and these car 4 and counterway 1.5 are connected to a main rope 6 wrapped around the sheave of the second part 3 of the winding. 7a and 7b are ventilation holes provided in the lower part and the second part of the hoistway 1, and this ventilation D7a.

7b is normally closed by ventilation Ji8a, 8b. 9a and 9b are driving devices such as electromagnets that move the ventilation doors 8a and 8b in the unidirectional direction; 10a and 10b are return springs;] 1 is when the temperature inside the hoistway 1 has reached a predetermined temperature, for example, 40 degrees or higher; When the switch closes, ]-2 is the relay, 1
3 is a switch that is turned on when the car 4 becomes unattended, and 14 is a relay that forces the car 4 into operation.

Now, when the temperature inside the hoistway reaches 40 degrees or higher, the switch 11 is turned on. This gives (+)-11
-C2- A (-) circuit is constructed, and the relay 12 is excited to close the contact 12a1.

By closing this contact 12a, (+) 12a
1-9a () and (10)-12a19b-(-) circuits are constructed of the electromagnet 9a.

9b is excited, the ventilation legs 8a, 8b are moved to the second part, and the ventilation lowers a, 7b are opened. Moreover, when the passenger compartment 4 becomes unmanned, the switch 13 is turned on. When the relay 12 is energized, the contact 2a2 closes, which causes (+)
-12a2-13-14(-) is configured, and the relay 14 is excited, so that the car 4 is forced to operate.

When the car 4 moves, for example, when the car 4 moves from below to above, the outside air is forcibly supplied into the hoistway 1 from the ventilation lower a, while the warm air inside the hoistway 1 Air is forced out from ventilation lower b. Also, ride and 4
Even if the elevator is unmanned, the switch 13 is turned on, the elevator is forced to operate, and forced air supply and exhaust into the hoistway 1 continues, making it possible to quickly measure the temperature drop in the hoistway.

When the temperature in hoistway 1 falls below 40 degrees, switch "-1"
, is 0FFL, and the relay 12 is demagnetized. As a result, the electromagnets 9a and 9b are demagnetized, and the return springs 10a and 10b are demagnetized.
Accordingly, the ventilation legs 8a, 8b close the ventilation lowers a, 7b.

According to the above embodiment, the ventilation lowers a and 7b are opened only when the temperature in the hoistway 1 is below a predetermined temperature.

In addition, when the car 4 is unmanned, the elevator is forced into operation to ventilate the inside of the hoistway, making it difficult for external dust to enter the hoistway 1, and preventing contamination caused by this dust. At the same time, the temperature inside the hoistway can be quickly maintained within a predetermined temperature range.

In this embodiment, electromagnets 9a and 9b are provided as driving devices for the ventilation doors 8a and 8b, but the same effect can be obtained even if a motor or the like is provided.

〔Effect of the invention〕

According to the present invention, the ventilation is opened only when the temperature inside the hoistway is above a predetermined temperature, so that the intrusion of external dust, etc. into the hoistway is minimized, and contamination is reduced. In addition, when the car is unattended, ventilation is forced into operation, so the temperature in the hoistway can be quickly maintained within a predetermined temperature range.
