Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a weighing device verification device for testing a weighing device of an elevator.

Generally, an elevator weighing device 10 is disposed between an elevator floor frame 8 and a support frame 5, as shown in FIGS. It is designed to work in response to the deflection of the vibrating rubber 7. In addition, in the figure, 1
is the upper beam, 2 is the main rope, 3 is the vertical column, 4 is the emergency stop, 6
is the key.

Elevator weighing device 10 configured in this way
The law requires that the test be conducted once a year, and traditionally this test was carried out by placing the rated weight x 1.
For example, an 11-seater elevator weighs about twice as much.
It is carried out by carrying a weight of 860 kg.

However, when testing a weighing device using such a method, a large amount of manpower is required for transporting and loading and unloading the weight, increasing elevator management costs. Moreover, since this verification work is time-consuming, it also impairs the service provided to passengers.

This invention was made in view of the above-mentioned drawbacks, and it is possible to provide a load device and a load meter on the car body, without placing a test weight on the floor of the elevator.
An elevator weighing device verification device capable of testing an elevator weighing device is provided.

An embodiment of the present invention will be described below based on FIG. 3. In the figure, 11 is a verification device;
11a is a pair of arms whose one end is hooked to the floor beam 8a of the floor frame 8; 11b is a connecting member whose both ends are connected to the pair of arms 11a, 11a, and has a threaded portion 111b in the center; 11c is a connecting member A load device consisting of a screwdriver such as a bolt that is screwed into the threaded portion 111b of the connecting member 11b, 11e is a support plate that is installed in contact with the lower surface of the emergency stop 4 and supports the load, and 11d is this support plate and the above-mentioned Load device 1
1c is a load meter made up of a load cell or the like, and 12 is a displacement meter made of a dial gauge or the like that shows the relationship between load and displacement.

With this configuration, when verifying the elevator weighing device 10, the screw of the load device 11c is screwed into the threaded portion 111b of the connecting member 11b, and the floor frame 8 and the support frame 5 or emergency stop 4 that supports it are connected. In the meantime, a displacement similar to that when a load is placed on the floor frame 8 is caused, and the weighing device 1 is
It is sufficient to verify the operating load of 0.

In addition, in the above explanation, the case was described where the displacement meter 12 was not installed, but if the displacement meter 12 is installed, once the amount of displacement of the floor frame 8 until the scale device 10 is activated is determined, it can be calculated from the verification load. Therefore, the operation of the weighing device 10 can be predicted with a small load, and furthermore, the verification work is simplified.

FIG. 4 shows another embodiment of the present invention, and in the figure, 11a is installed through a hole 8b provided in the center of the floor frame 8, has a threaded part at the upper part, and supports the lower part. A rod fixed to the plate 11e, 1
1c is a load device consisting of a nut or the like that is screwed into the threaded portion of this rod 11a and loads the floor frame 8; 11d;
11f is a load plate that distributes and loads a load on the floor, and is interposed between the load cell 11d and the floor frame 8.

Even with this structure, when verifying the elevator weighing device 10, the floor frame 8 and the Support frame 5 that supports
Alternatively, it is sufficient to generate a displacement similar to that of placing a load on the floor frame 8 between the emergency stop 4 and the load at which the scale device 10 operates using the load meter 11d.

In the case of this embodiment, in addition to obtaining the same effects as the embodiment shown in Fig. 3, the inspection work can be performed on the floor, making the work safer and easier. It's also effective.

FIG. 5 shows still another embodiment of the present invention, and the embodiment shown in FIG.
In contrast, in this embodiment, the load is applied between the floor frame 8 and the upper beam 1, and the load is applied between the floor frame 8 and the upper beam 1. This provides the same effects as the embodiment shown in FIG.

As described above, this invention provides a load device between the floor frame and the support frame or emergency stop that supports it, or the upper beam of the car frame, in order to verify the weighing device installed under the floor of the elevator. At the same time, a load meter was installed to verify the operating load of the weighing device, so the transportation of verification weights, which was previously done, was eliminated.
It is possible to carry out inspection work extremely easily and in a short time without carrying out inspection work that requires a large amount of manpower such as loading and unloading, which has the effect of reducing elevator management costs and improving service to elevator passengers. There is.
