Description

[Detailed description of the invention] This invention relates to an elevator system.

First, a conventional elevator system tube will be explained with reference to FIG.

In the figure, (1) is the elevator hoistway, electric 2) is the landing equipment installed there, and (2a) Fi landing equipment (2) is the elevator hoistway.
s (2b) is the door of the landing which formed the main part of the elevator shaft (2b) is the nine-hoisted joint installed on it, (3) is the rail installed on both sides of the hoistway (1), and (4) is the rail (3). ), (4a) is an entrance/exit provided there and facing the hall equipment (2), (4'b) U entrance/exit (4a)
The corner door that opens and closes* (4c) is provided on the car door (4b) and has a retaining piece that engages with the retaining piece (2b) in the main part;
(5) A well-known roller guide shoe that is provided on the heel (4) and has three rollers facing each side of the rail (3), (6) is a rail set up in the hoistway (1). The counterweight ()) is a transmission body consisting of a main rope, which is guided by the . The other end is connected to a counterweight 46).

That is, when the first hoist is energized, the heel (4) and the counterweight (61) are driven in opposite directions through the transmission body (7). The rail (31tlj) has a smooth mechanically-finished guide surface and is vertically installed in a predetermined position with precision. With such a rail (3), the ride comfort of the elevator is improved, and .

The movement of the car door (4b) causes the retaining piece (4C) and the engaging body (2
It is transmitted to the landing door (2a) through the connection in b).

Both the retaining piece (4e) and the engaging body (2b) are arranged at predetermined positions. However, there is a problem in that processing and erecting the rail 13> requires complicated labor and increases the manufacturing cost of the elevator.

The present invention aims to eliminate the above-mentioned drawbacks and to provide an elevator system that has a simple structure and provides the required car guiding action.

Below, Part 2. An embodiment of the present invention will be explained with reference to FIG.

In the figure, the same symbols as in FIG. 1 indicate corresponding parts.

(4d) A hanging frame placed at a distance in the depth direction from the center of gravity of the heel (4), (51i! A guide device attached to the hanging frame (4d) and facing the rail 3), will be described later, but the rail (3) that supports the unbalanced load of the car (4)
) is provided with a guide tool (5a) consisting of a roller that transfers in contact with the corresponding guide surface, and an opposing portion (5b) that faces away from the guide surface other than the upper corresponding guide surface.

(7a) It is attached to the ti hanging frame (4d) (4)
A transmission body (7
), at the connection part of (rb)Fi, the transmission body (
7) is a retainer.

That is, the connecting portion (Va) is provided apart from the center of gravity A, and an unbalanced load acts on the car (4).

By setting the position of the connecting portion (1a) as described below, the load in the horizontal force direction of the heel (4) is reduced to the guide tool (
Supported only by 5a). Namely.

In the case of a passenger elevator, the load on the car (4) is assumed to be offset at a position approximately 1/8 of the inner dimension from the center of the inner diameter of the car (4) when the car is at its rated load capacity.

Therefore, the hanging frame (
The position of the connecting portion (1a) is set so that the rotational moment generated in the car (4d) is larger by □t·1° than the rotational moment generated by the deviation of the loaded load of the car (4).

That is, point A shown in Figure 2 is (4) center of gravity.

Point B is the connecting part (1a), that is, the hanging core, and point 0 is the point (4).
Assume that the center of the unbalanced load is the center of the load.

Supported only by a). For this reason, rail (3)
Even if there is a V, mutual spacing error, etc., the heel (4) is guided in a state in which it is pressed to one side in the horizontal direction. Therefore, the relative position of the engagement piece (4c) and the engagement body (2b) can be maintained in a predetermined state. Furthermore, even if a part of the passenger moves within the heel (4), no lateral oscillation occurs in which the heel (4) is held horizontally and pressed to one side. Furthermore, the guide surface of the rail (3) does not need to be particularly smooth, and suitable steel sections such as H section steel and lipped channel steel can be used as they are, and can be manufactured at low cost. Also, the guide device (5)
can be manufactured at low cost since it is only necessary to provide the guide tool (5a) only at a location facing the required rail+31 guide surface. In addition, when abnormal lateral shaking occurs in the heel (4) due to an earthquake, etc., the opposing part (5b) of the guide device (5) moves to the rail +3.
), it is possible to prevent the rail from falling off (3).

In addition, in the case of cargo elevators, etc., the degree of deviation is taken into consideration depending on the actual load situation.11,7j

As explained above, the present invention connects the car to a transmission body at a position away from the center of gravity at least in the frontage direction on the plane of the car to generate an uneven load on the car, and the car has a structure corresponding to the above-mentioned uneven load support of the rail. A guide tool placed in contact with the guide surface is provided so that the car is always kept at a minimum of 6 in the horizontal direction.
It is designed to be guided in a pressed state at least to one side in the frontage direction. As a result, an inexpensive elevator system is realized in which the car can be normally raised and lowered by easily manufactured and erected rails and by simply configured guide tools.
