Abstract

PROBLEM TO BE SOLVED: To provide an elevator device having a large degree of freedom for the fitting positions of a winder and an apparatus in a hoistway without applying a large load to the wall of a building and a specific guide rail in an elevator having no machine room. SOLUTION: The winder 5 is fixed to a fitting member 30 fixed to a car guide rail 4 and a counterweight guide rail 13 in a space by a projection face in the lift direction of a car 2 and a space with the wall of the hoistway 1 at the lower section of the hoistway 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an installation structure of a hoist in an elevator without a machine room, and more particularly, to installing a hoist between a space defined by a projection plane of a car in a hoisting direction and a hoistway wall. About elevators that do.

[0002]

2. Description of the Related Art In recent years, there has been a demand for space saving in elevators, and elevators without a machine room are increasing. At this time, the hoist may be installed at the upper part in the hoistway or at the lower part.

FIG. 3 shows a conventional example in which a hoist is installed above a hoistway, and FIG. 4 is a plan view of FIG. In the figure, 1 is a hoistway, 2 is a car, 3 is a counterweight, 4 is a guide rail for a car that guides the car 2 to go up and down, and 5 is a hoist fixed to the guide rail 4 by an attachment member 6. , 7 are traction sheaves. Reference numeral 10 denotes a main rope, one end of which is attached to the fixed portion 11 at the upper part of the hoistway 1. The other end passes through the sheaves 2a and 2b of the car 2, the traction sheave 7, and the sheave 3a of the counterweight 3 and the other end. Is attached to the upper fixed part 12. 13 is a guide rail for counterweight, 14
Is a landing doorway.

FIG. 5 shows a conventional example in which the hoisting machine 5 is installed below the hoistway 1, and FIG. 6 is a plan view of FIG. In this example, the hoisting machine 5 is fixed to the wall of the hoistway 1 by the mounting member 20. Numerals 21 and 22 are sheaves attached to the upper part of the hoistway 1, and the same reference numerals as those in FIGS.

[0005]

In the case of the examples shown in FIGS. 3 and 4, since only one guide rail 4 supports all the loads acting on the hoisting machine 5, the guide rail 4 has a large strength. Or reinforce it. Further, since the installation position of the hoisting machine 5 is limited to the position of the guide rail 4, there is a problem that the arrangement of various devices in the hoistway 1 is restricted.

In the case of FIGS. 5 and 6, since the load acting on the hoisting machine 5 is supported by the wall of the building, it is necessary to strengthen the wall structure. There is also a problem that the installation position of the hoisting machine 5 is often limited by the shape and structure of the building.

[0007]

SUMMARY OF THE INVENTION The present invention provides a guide rail and a counterweight for a car in a space below a hoistway and between a space defined by a plane of projection of the car in a hoisting direction and a wall of the hoistway. The hoisting machine is fixed to a mounting member fixed to the guide rail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. 1 and FIG. In the drawing, reference numeral 30 denotes a mounting member of the hoisting machine 5, and the upper support beam 3
1, lower supporting beam 32, upper and lower supporting beam 31,
It consists of a base 33 fixed to a lower support beam 32. One side of the upper support beam 31 and the lower support beam 32 is clipped to the car guide rail 4 and the other side is connected to the counterweight guide rail 13. Clipped.

According to this embodiment, the load acting on one guide rail is reduced, so that a relatively low strength guide rail can be used or no reinforcement is required. Further, since the hoisting machine 5 is fixed to the mounting member 30, the degree of freedom of the mounting position of the hoisting machine 5 in the horizontal direction is increased, and thus the degree of freedom of arrangement of other devices is also increased. Furthermore, since the load is supported by the guide rails 4 and 13, the burden on the building is small, and the mounting position of the hoist is not restricted by the shape and structure of the building. Also, the degree of freedom of the mounting position is increased.

In the above-described embodiment, the case where the counterweight 3 falls on the opposite side of the landing entrance 14, that is, when the counterweight 3 falls behind the car 2, is described. However, the present invention can be similarly implemented.

[0011]

As described above, according to the present invention,
It is possible to realize an elevator apparatus which does not impose a large burden on the walls of the building, has a relatively small load on the guide rails, and has a high degree of freedom in mounting positions of the hoist and the equipment in the hoistway.
