EXAMPLE

The following describes an embodiment of the present invention as follows.

Example 1.

An embodiment of an elevator without a machine room according to the present invention will be described with reference to FIG. 1. 1 is a cross-sectional view showing a cross section of an elevator without a machine room of Embodiment 1 of the present invention.

1 to 10 are the hoistway of the elevator. 11 is an elevator car (hereinafter simply referred to as a 'car') in the hoistway 10, and 12 is an opening and is formed on the wall or ceiling surface in the car 11. A part of the wall surface and a part of the ceiling surface in the car may be integrally opened in the car, and the opening 12 may be open in the car separately from a part of the wall surface and a part of the ceiling surface.

13 is a switch and controls the operation of the elevator when the opening 12 is opened.

14 is a motor and is installed in the top of the hoistway 10. 15 is a sheave and is provided on the top wall side of the hoistway 10, and is provided between the hoistway wall and the car 11 when the car 11 is at the top of the hoistway. 16 is a belt and decelerates and transmits the driving force of the motor 14 to the sheave 15. 17 is a winch and consists of a motor 14, a sheave 15 and a belt 16. 18 is a wire rope and is wound around the sheave 15, one end fixed to the car 11 and the other end fixed to the counterweight 19. 20 is a car guide rail. 21 is a counterweight guide rail. The sheave 15 is installed above the counterweight guide rail 25.

In addition, II Ⅱ sectional drawing of the elevator which does not have a machine room shown in FIG. 1 is shown in FIG. In addition, in FIG. 2, the same code | symbol is attached | subjected to the part same as that shown in FIG. 1, and the description is abbreviate | omitted.

3 is a sectional view taken along the line III-III of the elevator without a machine room shown in FIG.

3, 30 is a car fixing device. In the car fixing device 30 of the present embodiment, the plate attached to the car guide rail 20 is fixed to the car 11 by using a lock bar from the inside of the car.

The car fixing device 3 is not limited to this example. This car fixing device 30 is used when it is necessary to fix the car 11, such as during maintenance work.

3 to 6, the same or equivalent parts are denoted by the same reference numerals, and the description thereof will be omitted, and a part different from FIG. 1 will be described.

Thus, the sheave 15 is provided by providing the opening 12 in the wall surface of the car 11 or the like, by providing the sheave 15 of the hoisting machine 17 having a high necessity for maintenance work between the car 11 and the hoistway wall. ) Can be easily repaired in the car.

In addition, when carrying out maintenance inspection of the sheave 15 etc. in a car, the car may be in the uppermost floor, and may be slightly upward or downward from the uppermost floor.

The vicinity of these top floors is taken as the top of the hoistway. In addition, moving a car in the vicinity of the uppermost floor is based on the predetermined operation using a switch.

In addition, since the sheave 15 provided on the side of the car 11 can be easily repaired in the car interior through the opening 12, the foot can be safely repaired directly on the floor without using a footrest in the car.

In addition, since the car can be repaired, it is not necessary to climb on the car and perform maintenance checks, and the handles provided on the car can be removed, thereby reducing the spatial dimension of the top of the elevator.

In addition, since the sheave 15 and the reducer portion of the winch 17 can be provided between the car 11 and the hoistway wall, the parts installed on the top of the car at the top of the hoistway can be kept to a minimum, and the space at the top of the elevator. The dimension can be made small.

The method of suppressing the top dimension of these elevators can be realized at low cost.

In addition, if the sheave 15 or the motor 14 of the winch 17 can be made thin, the installation space of the elevator can be further miniaturized by the layout as in the present embodiment, which makes the building space more effective. It can be utilized.

Example 2.

Another embodiment of an elevator without a machine room according to the present invention will be described with reference to FIG. 4.

4 is a cross-sectional view showing a cross section of an elevator without a machine room of Embodiment 2 of the present invention. In FIG. 4, 40 is a car side wire rope fixing part, which is installed in the hoistway 10 and one end of the wire rope 18 is fixed. 41 is a car turnaround pulley and is installed below the car 11. 42 is a counterweight forward pulley and is installed on the counterweight 19.

43 is a wire rope fixing part on the counterweight side, and is installed in the counterweight guide rail 21 or the hoistway 10, and the other end of the wire rope 18 is fixed.

In this way, in the elevator without the machine room of the present embodiment, one end of the wire rope 18 is fixed to the car side wire rope fixing part 40 and passes through the car turning pulley 41, the sheave 15, and the counterweight turning pulley 42. The other end is fixed to the counterweight guess wire rope fixing portion 43.

Such a configuration is called a 2: 1 roping configuration.

In addition, in FIG. 4, the same code | symbol is attached | subjected to Example 1 shown in FIG. 1, the description is abbreviate | omitted, and the part different from FIG. 1 is demonstrated.

5 is a cross-sectional view taken along line V-V of the elevator without a machine room shown in FIG. In Fig. 5, the same or corresponding parts as those shown in Fig. 4 are denoted by the same reference numerals and the description thereof is omitted.

By using the 2: 1 roping configuration in this manner, the load on the winch 17 can be halved, and the motor and the like can be miniaturized.

For this reason, the spatial dimension of the top part of an elevator can be suppressed by the layout of the winch | winder 17 of a present Example.

Moreover, since the opening part 12 was provided in the wall surface of the car 11, the maintenance of the sheave 15 etc. which were provided between the hoistway wall and the car 11 can be performed simply and safely.

In addition, since it is not necessary to climb on the car 11 and perform maintenance inspection, the handle provided on the car can be removed, and the space dimension of the top of the elevator can be suppressed.

Example 3.

Another embodiment of an elevator without a machine room according to the present invention will be described with reference to FIG. 6. Fig. 6 is a sectional view showing a cross section of an elevator without a machine room according to the third embodiment of the present invention.

The handle 51 is for securing work on the floor of the car of the maintenance staff. 52 is a door (opening part) provided in the wall surface of the car 11, and this door 52 can be opened and it can go out to the car bottom 50 extended outward of the car 11. As shown in FIG. 53 is a switch and the operation of the elevator is controlled when the door 52 is opened. 54 is a control unit mounted on the wall of the hoistway.

Thus, the elevator without a machine room according to the present embodiment is to install the sheave and the motor of the hoisting machine above the car bottom 50 extending out of the car 11 from the top wall side of the hoistway 10, and the hoistway ( Nothing is installed between the ceiling of 10 and the ceiling of the car 11.

For this reason, the maintenance staff opens the door 52 of the car wall and checks the sheave 15, the motor 14, and the like of the winch 17 on the car floor extended outside the car.

In Fig. 6, the same or equivalent parts as those of the first embodiment shown in Fig. 1 are denoted by the same reference numerals, and the description thereof will be omitted, and the different parts from Fig. 1 will be described.

6 is a cross-sectional view of the elevator without a machine room shown in FIG. 6. In addition, in FIG. 7, the same code | symbol is attached | subjected to the part same or equivalent to what is shown in FIG. 6, and the description is abbreviate | omitted.

As such, the maintenance staff can perform maintenance work outside of the car, thereby widening the scope of the maintenance staff's behavior and repairing the control device installed on the hoistway wall.

In addition, the sheaves and motors of the hoisting machine are installed above the car floor outside the car, and the maintenance is performed on the car floor, so that maintenance work on the upper surface of the car 11 is unnecessary, and the handle provided on the upper surface of the car 11 is removed. It is possible to reduce the space dimension of the top of the elevator.
