Description

[Detailed Description of the Invention] This invention relates to an improvement of a fixing device that can be used when installing an elevator.

When installing an elevator car, it must first be secured to the emergency stop that serves as its foundation within the hoistway.

This work is carried out using the emergency stop device.

This will be explained with reference to FIGS. 1 to 3. In Figure 1, 1
2 is the elevator car, 2 is the emergency stop frame supporting the foot 14, 3 is the emergency stop device stored in the emergency stop frame 2,
When the elevator speed of the car 1 reaches an abnormal speed that exceeds the rated speed, the speed governor (not shown) detects this sound and pulls the car up to the brake 3a' via the speed governor rope (not shown) 4. The guide rails erected on both sides of 1 are designed to hold the 4 metals in place so that the 1 metal can come to a sudden stop.

5 is a fixture fixed to the emergency stop frame 2 and extending upward;
6 is a cage frame fastened to the fixture 5, and 7 is a main rope from which the cage frame 6 is suspended.

In this way, the car 1 is guided by the guide rails 4 and moves up and down.

In FIGS. 2 and 3, reference numeral 8 indicates a pull-up lever having a pin 9 connected to the governor rope, and 16 indicates an emergency stop frame 24.
A main shaft passes through the shaft and has a pull-up lever 8 fixed to one end and an operating lever 11 fixed to the other end, 12 is a pin provided on the brake 3a and connected to the tip of the operating lever 11, and 13
is a rope with one end connected to a suitable position in the hoistway and the other end connected to pin 9, and is used only during installation.

Now, the installation work begins by erecting four guide rails on the hoistway.

Then, the emergency stop frame 2 in which the emergency stop device 3 is housed is carried in, and the brake 3ak is placed opposite the guide rail 4.

At this time, the rope 13 is connected to the hoistway.

Next, when the emergency stop frame 24 is moved downward, the pull-up lever 8 is pulled by the rope 13 and rotated, so that the operating lever 11 also rotates via the main shaft 10 metal.

As a result, the brake 3a is pulled up and clamps the guide rail 4, so that the emergency stop frame 2 is fixed to the guide rail 4.

The emergency stop frame fixed in this way will be assembled with one metal as a two-metal foundation.

Therefore, when installing the emergency stop frame 2, alignment, levelness, etc. are constantly required.

However, since the emergency stop frame 2 is lowered as described above, it is difficult to make the brake 3a hold the guide rail 4 metal while the emergency stop frame 2 is in a horizontal state.

1. It is also difficult to align the emergency stop device 3 with respect to the guide rail 4 in the left and right direction.

Therefore, for cases that fall within these metal tolerances, the above-mentioned work must be repeated several times, and installation work is poor. To provide an elevator fixing device which can be easily and quickly clamped to a guide rail.

Hereinafter, one embodiment of this invention will be explained with reference to FIGS. 4 and 5.

In the figure, reference numeral 14 denotes a lifting device consisting of a jack bolt provided on the emergency stop frame 2 and supporting the lifting lever 8.

The rest is the same as in FIGS. 2 and 3. However, rope 1
3 is not used.

When the emergency stop frame is carried between the 2-metal guide rails 4 and leveled, the lifting device 14-metal is pushed up, the main shaft 10 rotates via the lifting lever 8, and the actuating lever 11 also rotates, so the brake is activated. Child 3a can move up and down.

Therefore, the brake 3a can be made to clamp the guide rail 4 without moving the emergency stop frame 24.

Since the alignment and levelness of the emergency stop device 3 can be adjusted in advance and the safety stopper can be operated in that state, the alignment and levelness will not be disturbed.

FIG. 6 shows another embodiment 4 of this invention.

In the figure, 15 is a support arm fixed to the fixture 5, 16 is a threaded rod whose lower end is connected to the pin 9 and has a screw metal at the upper end, into which the support arm 15 is loosely fitted, and 17 is a support arm. It is a handle that is screwed onto a threaded rod 16 above the arm 15.

When the handle 17 is rotated, the threaded rod 16 moves upward and the pull-up lever 8 rotates, so it is possible to perform the same operation as in the above embodiment.

In each of the above embodiments, the brake lever 3ak is operated through metal such as the lifting lever 8, the main shaft 10, and the operating lever 11. It is also possible to do so.

As explained above, in this invention, the emergency stop device is attached to the side of the guide rail and the emergency stop device facing this surface by manually braking the emergency stop device without moving the body of the frame on which the emergency stop device is installed. A lifting device 4 is provided that can be inserted between the slope of the car and the brake guide rail is clamped by the operation of this lifting device, so that the sound of installing the frame, which is the basis for assembling the car, can be easily and accurately reduced. installation time and noise can be reduced.
