Abstract

PURPOSE:To make it possible to perform confirmation of the operation of a scaling device efficiently, by mounting load devices, in which liquid is accommodated, on a cage, and confirming the operation of the scaling device. CONSTITUTION:In confirming the operation of a scaling device 1 for an elevator, load devices 8, wherein liquid 8a is accommodated, are mounted on a cage in place of conventional steel bodies. As the liquid 8a, e.g., water is used. A scale line 8b indicating the amount of the accommodated liquid is provided on the load device 8. The load devices 8, in which a specified amount of the liquid 8a is accommodated, are brought on the cage so that a specified weight is obtained. Then the operation is confirmed. Therefore, a conveying means of a heavy material such as the steel bodies can be alleviated and warehouses for the heavy material can be omitted. Thus, the confirmation of the operation of the scaling device 1 can be performed very efficiently.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a labor-saving means for installing an elevator, and more particularly to a test method for an elevator scaffold device for detecting overload of an elevator. It is.

[Background of the invention]

Generally, the performance of an elevator is comprehensively evaluated based on various items such as technical level such as high speed, power saving, and control intelligence, safety, ease of installation, and maintainability to determine its commercial value.

Recent elevators have significantly advanced service functions through the adoption of electronic technology, and are now being used as safe and comfortable transportation equipment. However, when considering the efficiency of installation work and maintenance, the following problems remain due to the environment in which elevators are installed.

In other words, elevator equipment uses a so-called on-site installation method in which its component parts are manufactured at a manufacturing factory and the overall assembly work proceeds in accordance with the construction process of the building. They are often constrained by this and are forced to work in extremely inefficient ways. Also,
The harsh working conditions at this site are exacerbated by the product-specific configuration of the elevator itself, in which equipment is distributed throughout the hoistway, in the upper and lower machine rooms, and at each entrance and exit.

Therefore, in order to meet the demand for shortened delivery times, which is considered one of the overall performance of elevators, it is essential to take various measures, including reducing the number of parts, simplifying the design of the structure, and improving installation ease. On the other hand, this type of improvement is also necessary for maintenance and inspection work to check the elevator function and safety, and the improved maintainability is effective in reducing elevator downtime.

Here, one of the bottlenecks in installation and maintenance work has been testing work to check the operation of the replacement device. This weighing device is compatible with the Statutory Building Standards Act Enforcement Ordinance 12.
9 of 9. This is a safety device in item 12 (a), which stops the elevator from starting when a load exceeding approximately 110% of the live load is loaded, but the test work to confirm its operation has traditionally been inefficient. is considered typical.

Up to now, the two methods shown in FIGS. 1 to 3 have been the main methods for checking the operation of a security device.

In general, the scale device 1 is located below a box-shaped passenger seat 6 made up of a main frame 2, a side panel 3, a door 4, and a floor plate 5, and is installed between the main frame 2 and the floor plate 5. The subsidence of the contracted body 7 is detected. When the gap g between the floor plate 5 and the switch S forming the scaffolding device 1 disappears due to the passenger load, the elevator is completely stopped by electrical means.

The conventional method for checking the operation of the evacuation device 1 is the second
As shown in the figure, there is a method of placing a steel body W corresponding to the live load on the floor 5. Another method is to pull the metal fitting K fixed to the floorboard 5 toward the main frame 2 by rotating the pole B, and convert the amount of pull (change in gap) of the pole B into the live load. This is for checking the operating status of the weighing device 1.

Among the methods described here, the method using the steel body W has the problem that a great deal of labor is expended in transporting the steel body W from the storage warehouse to the installation site (transportation means) and within the site (hand-held). However, there are drawbacks that require special consideration, such as curing when transporting the vehicle into the carriage and preventing it from slipping. In addition, the method using POL) B has disadvantages in terms of cost required for attachment to the metal fittings, as well as drawbacks in terms of reliability due to loosening of POL) B itself over time. There are problems with the working space below.

It can be seen that there is room for improvement in the conventional test method for verifying the operation of elevator transport systems as described above.

[Purpose of the invention]

In view of this point, the present invention has been made in order to provide a test method that can efficiently check the operation of an elevator insulating device.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described based on the drawings. Fourth
In the figures and FIG. 5, the structure of the rider and the rider 6 indicated by the same reference numerals as in FIG. The test method is characterized in that the operation of the device 1 is confirmed by placing it on the handle 6. Here, as the liquid 8a, for example, water sanitation or industrial liquid is used, and the load device 8 that stores the liquid is provided with a scale line 8b that clearly indicates the amount stored. Then, the operating status of the lid device 1 is checked by bringing the loading device 8 containing a certain amount of liquid 8a, which is visually measured by the scale line 8b, into the passenger car 6 in the number of people that will form a predetermined loading type lid. It has become.

In this case, the storage capacity of the load device 8 is preferably about 20 to 30 kg so that the installation or maintenance personnel can carry it without any burden.
The load device 8 may be more effective if it is provided with a handle for convenient carrying and a measure to prevent the liquid 8a from scattering.Furthermore, it can be made into a low-cost item such as a plastic bag and made disposable. The water used as the liquid 8a is extremely easy to handle as it can be easily obtained at the site where the elevator is installed and can be disposed of anywhere after the test.

The load device 8 described above not only requires less transportation means such as the steel body W shown in FIG. 2, but also does not require a warehouse for storing heavy objects. In addition, the cost aspect explained in Figure 3,
Problems such as reliability and work space can be solved all at once.

〔Effect of the invention〕

As described above, the method for testing an elevator cover device of the present invention has the effect that the operation of an elevator cover device can be efficiently checked.
