Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator system in which an emergency stop device can be engaged with a rail by a simple operation.

First, based on Figures 1 and 2, for example,
A conventional elevator system similar to that shown in Publication No. 21727 will be described.

In the figure, 1 is the elevator hoistway, 1a is its pit, 2 is a platform fixed to the bottom of the pit 1a,
3 is a shock absorber erected in the center of platform 2; 4 is a rail erected from each end of platform 2 to hoistway 1;
4a is an end face of the rail 4, 4b is a side surface, 5 is a counterweight, 6 is a rail fixed to the hoistway 1 and guides the counterweight 5, 7 is assembled in a square shape and is suspended from the main rope 8. 7a is a side wall of the frame 7 whose cross section is groove-shaped and the groove is loosely fitted into the rail 4; 9 is an emergency stop device formed on the lower side of the frame 7; A fitting portion 9a that fits into the rail 4 is provided. 10 is a frame 7
The cage 11 provided inside is attached to the upper surface of the frame 7 and the lower surface of the emergency stop device 9, respectively, and is connected to the rail 4.
It is a guide tool movably engaged with.

That is, when installing an elevator, the rail 4 is erected and the emergency stop device 9 is fitted onto the rail 4. Next, the frame body 7 is assembled, the guide tool 11 is attached, and the cage 10 is also assembled. The equipment disassembled in this way is assembled in the hoistway 1,
The inside of the hoistway 1 is narrow and the working conditions are poor, and installation requires complicated and difficult work, and there are also problems that require a lot of time.

The present invention aims to overcome the above-mentioned drawbacks and provides an elevator system in which the assembled frame can be easily engaged with the rails and can be easily installed.

An embodiment of the present invention will be described below with reference to FIGS. 3 to 5.

In the figure, the same reference numerals as those in Figures 1 and 2 indicate corresponding parts, and numeral 7 indicates steel materials assembled in a shape.
The frame body 9 having a side frame 7a disposed facing the frame body 7 is an emergency stop device fastened to one side of the vertical surface of the frame body 7 by a fastener 9b, and the frame body 9 is connected to the side face 4b of the rail 4. The fitting portion 4c of the emergency stop device 9 having dimensions A and B shown in FIG. This is a notch having dimensions C and D larger than A and B.

That is, the emergency stop device 9 is carried into the hoistway 1, and the fitting portion 9a is fitted into the rail 4 which is erected. Next, the frame 7 assembled outside the hoistway 1 and at the factory is carried into the hoistway 1 and the emergency stop device 9
are fastened by the fasteners 9b, and the guide tool 11 is attached to the frame body 7, resulting in the state shown in FIG. 4. Thereby, the frame body 7 can be assembled outside the hoistway 1, the work inside the hoistway 1 is reduced, and an elevator system that can be easily installed is obtained.

In addition, in this embodiment, the rail 4 has a notch 4c.
Since this is provided, the following effect can be obtained incidentally.

That is, the assembled frame 7 with the emergency stop device 9 attached thereto is carried into the pit 1a, and the fitting portion 9a is fitted to the rail 4 through the notch 4c. Then, the frame body 7 and the like are pulled up, and the shock absorber 3 and guide tool 11 are attached, resulting in the state shown in FIG. 4. As a result, the frame body 7 and the emergency stop device 9 can be assembled outside the hoistway 1 or in the factory, and the work inside the hoistway 1 is reduced, so that an elevator system that can be easily installed is obtained. In addition, the frame body 7
A notch 4c is provided at a position where the guide 11 does not come off the rail 4 even when the shock absorber 3 is compressed by pushing down the cage.

FIG. 6 shows another embodiment of this invention,
In the figure, the same reference numerals as in FIG. 4 indicate corresponding parts, 4e is a leg of the rail 4 whose one end is fixed to the base 2 and the other end is fixed to the lower end of the rail 4, and 4c is formed by the lower end surface of the rail 4 and the leg 4e. This is the cutout.

That is, it is clear that even with such a notch 4c, the same effect as in the embodiments shown in FIGS. 3 to 5 can be obtained.

7 and 8 also show other embodiments of the present invention, in which FIGS. 3 to 5 show corresponding parts;
7 is a rail formed on the other side of the stringer 13 that supports the landing device 12 on one side, and 7 is the car door device 14.
It is a frame body that supports the emergency stop device 9 and is equipped with an emergency stop device 9.

That is, in this embodiment as well, the emergency stop device 9 is provided on one side of the vertical surface of the frame 1, and the assembled frame 7 with the emergency stop device 9 and the car door device 14 is installed in the pit 1a. The fitting portion 9a of the emergency stop device 9 can be fitted to the rail 4 through the notch portion 4c after being carried in. Therefore, detailed explanation will be omitted, but in this embodiment as well, the third to fifth
It is clear that a similar effect to the illustrated embodiment can be obtained.

As explained above, the present invention is assembled by providing the lower ends of the rails, which are set upright in the hoistway facing each other, with a notch that opens at the end face of the guide part and is larger than the fitting part of the emergency stop device. The emergency stop device can be engaged with the rail, and a square-shaped frame is fastened to one side of the emergency stop device at a position offset from the rail, so the emergency stop device can be engaged with the rail. After that, the assembled frame can be carried into the hoistway and fastened to the emergency stop device, thereby realizing an elevator system that reduces work in the hoistway, is easy to install, and reduces installation costs. be.
