Description

[Detailed Description of the Invention] (Industrial field of application) This invention is a traveling crane equipment that can be stored in the ceiling above the ceiling installed in factories or showrooms where a good environment is required to be preserved. Regarding

(Prior Art) When a heavy object is transported in a factory or the like, an overhead traveling crane is generally used.

This overhead traveling crane is a traveling girder traveling (longitudinal) on a traveling rail provided on the ceiling by a traveling device, and a trolley (horizontal traveling on the traveling girder in the longitudinal direction thereof) for elevating and lowering a transported object. This means a concept including a traveling type hoist type, which is the same in this specification), and a traverse device which is a drive device for traveling of this trolley.

In factories and the like equipped with the above-mentioned overhead traveling crane, the height from the floor is generally quite high because of the nature of lifting things to be transported upwards and moving them above other objects installed on the floor. , The air conditioning, lighting, etc. are not as good as those in ordinary offices, and the traveling girders and traverse devices are exposed, so it cannot be said that the appearance inside the building is more beautiful than in ordinary offices. .

Therefore, where good air conditioning, certification, etc. are required, and where beauty in appearance is required in the building, even though it is known that it is excellent in transporting heavy goods inside the building, Without attaching such an overhead traveling crane, heavy goods were carried by a simple carrying device such as a lifter or manually.

(Problems to be solved by the invention) By the way, in recent years, especially in the factory that produces high-value-added brain-intensive products, etc., it is suitable for brain labor from the factory having the conventional structure of production efficiency. There is a growing demand for factories that have an environment (aesthetics, air conditioning, certification). However, even in such an environmentally excellent factory, due to the nature of the factory, the layout of the equipment and the like is changed or the equipment is brought in as appropriate, so it is better to make the above layout changes efficiently. There is no.

Further, in a showroom, museum, or the like that requires good environment as described above, it is often necessary to carry in and carry out a heavy product or work, and conventionally, even in such a building, such work has to be carried out. There has been a demand for a transfer facility that can be easily carried out.

The present invention has been made in view of the above-mentioned current situation, and provides a traveling crane of a ceiling storage type capable of carrying heavy objects inside while maintaining good environment such as aesthetics in a building. The purpose is to

(Means for Solving the Problem) The ceiling stowage type traveling crane equipment according to the present invention is divided into a ceiling surface configured to be movable up and down from a position below a traveling rail to a position above the traveling rail, and this ceiling. Ceiling storage traveling crane having a traveling rail arranged on a side portion of a building part that does not planarly interfere with a surface and a traveling crane main body arranged on the traveling rail so as to travel freely in a direction orthogonal to the traveling rail. When used as a traveling crane, the ceiling surface portion of the divided ceiling surface where the traveling crane body is not located above the divided ceiling surface first rises, and then the traveling crane below the raised ceiling surface portion. Controls so that the main unit moves, and then the remaining ceiling part, which could not be raised due to the presence of the traveling crane main body, is raised, and the traveling crane is stored behind the ceiling. When doing so, it characterized in that it has a control means for controlling to operate in the reverse order.

(Operation) However, when using the overhead stowage type traveling crane equipment configured as described above, when each ceiling portion is lifted by the above procedure and the traveling crane main body is moved below the ceiling portion, the normal operation can be easily performed. Can be used as an overhead traveling crane, while on the other hand, when not used as a traveling crane, the traveling crane body can be easily stored in the back of the ceiling in the reverse procedure.
The ceiling surface is located below the traveling rail and traveling crane main body, which are the lowered positions, and these are housed behind the ceiling. Therefore, the appearance of the interior of the building below the ceiling surface can maintain the same aesthetic appearance as an ordinary beautiful office.

Moreover, like a conventional overhead traveling crane, it can be transported or moved in a planar manner to all parts inside the building.

In addition, an air-conditioning outlet or suction port is provided on this elevating ceiling surface, and these are connected by a fixed air-conditioning duct and a flexible duct in the back of the building ceiling. By connecting to the electric wire on the side of the building, the height under the ceiling can be reduced compared to the conventional factory,
It is easy to maintain the air conditioning and lighting in good condition as in a normal office.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing the overhead traveling traveling crane equipment according to this embodiment, FIG. 2 is a view taken along the line II of FIG. 1, and FIG.
The figure is a flow chart showing the control procedure of the control device.

In the figure, reference numeral 1 denotes a ceiling surface, and this ceiling surface 1 is divided into a plurality of portions, in the present embodiment, two portions (ceiling surface portions) 1A and 1B, and these ceiling surface portions are respectively provided at four corners via wires. And is suspended by four hoists 2 (see FIG. 2). The hoist 2 is suspended from the structure of the building above the hoist 2, and the wire wound around the built-in drum is taken in and out to raise and lower the ceiling surface portion.
In this embodiment, in order to prevent the positions of the four corners of the ceiling surface portion from changing due to the use due to the extension of the wire due to use, between the four corners of the building and each ceiling surface portion at the rising position for each lifting operation. An attached position detection limit switch (not shown) is operated to determine the raised position of each hoist 2 each time, and its extension does not affect the position control. Further, a position detection limit switch (not shown) for detecting the descending position of the ceiling surface 1,
It is attached to the ceiling descent position of the building.

Also, on the building side that abuts the four corners of each of the ceiling surface portions 1A, 1B, as shown in the figure, a guide rail 3 is arranged vertically,
Each ceiling surface portion is configured to move up and down along the guide rail 3. Further, traveling rails 4 are arranged on both sides of the building that do not interfere with the ceiling surface 1 in plan view. A traveling crane main body A is mounted on the traveling rail 4 so as to travel freely on the traveling rail 4.

The traveling crane main body A is composed of a traveling girder 5, a trolley 7, etc., and the traveling girder 5 is configured to drive the front wheels attached to the traveling girder 5 by a traveling electric motor 6 to travel on the traveling rail 4. ing. Further, as shown in FIG. 2, a trolley 7 having a traverse device 7A for traveling (traversing) on the travel girder 5 and a hoisting device 7B is placed on the travel girder 5.

By the way, in the case of the present embodiment, the respective driving parts of the hoist 2, the traveling electric motor 6, the traverse device 7A, and the hoisting device 7B are
For convenience of operation, it is configured to be remotely operated by wireless.

Then, when the traveling crane main body A is housed under the ceiling or the traveling crane main body A is exposed under the ceiling during use by a control device (not shown), the procedure shown in the flowchart of FIG. Such control is performed. The control device can be formed by either a sequence circuit or a micro computer.

That is, as shown in FIG. 4 (a), when the traveling crane main body A stored in the ceiling is to be used, the traveling crane use button (not shown) is turned on, and the control device is activated. Then, the traveling crane main body A is at a predetermined position (in this embodiment, the ceiling portion 1A at the boundary between the ceiling portions 1A and 1B).
Side), and as shown in Fig. 4 (b),
Above ceiling part 1B where traveling crane body A does not exist above
But rises. In this state, at the position below the ceiling portion 1B, the wires of the hoist 2 and the like disappear as the ceiling portion 1B rises, and the traveling crane body A can move freely on the moving rails.

Then, when the rise of the ceiling portion 1B is confirmed by the action of the limit switch, the traveling crane main body A then
As shown in FIG. 4 (c), it moves to a position below the ceiling portion 1B. In this state, there is no traveling crane body above the ceiling portion 1A, and there is nothing that can prevent the ceiling portion 1A from moving upward.

When it is confirmed that the traveling crane main body A has moved below the ceiling portion 1B, next, as shown in FIG. 4 (d), the ceiling portion 1A reaches the same height position as the ceiling portion 1B. To rise.

In this state, the traveling crane (traveling crane main body and traveling rail) is exposed below the ceiling surface 1, and nothing prevents the traveling crane main body A from moving on the traveling rail 4. Therefore, it can be used in the entire building as a normal overhead traveling crane.

On the other hand, when the traveling crane main body A is to be housed in the ceiling, the above procedure is reversed, that is, the traveling crane main body A is first moved to a position below the ceiling portion 1A, and when this movement is confirmed, the ceiling portion 1B is detected. Goes down. When this drop is confirmed,
When it is confirmed that the traveling crane body A has moved to the end of the ceiling portion 1B on the boundary side with the ceiling portion 1A, and then the traveling crane body A has completely moved to the ceiling portion 1B, the ceiling portion 1A
Goes down. When this descent is confirmed, the traveling crane main body A is moved to a predetermined position (in this embodiment, the ceiling parts 1A, 1
The control is performed so that it returns to the ceiling portion 1A side of the boundary portion of B) and stops.

In this state, the traveling crane main body A is housed behind the ceiling and only the ceiling surface can be seen from below as in a normal office or the like.

In the above embodiment, the position of the traveling crane body A is detected by the limit switch.

In addition, in the case of the above-mentioned overhead storage type traveling crane equipment of the present embodiment, although not shown in the figure, the air outlets of the air conditioning equipment are formed downward in each of the ceiling portions 1A and 1B. This outlet is connected to a duct fixed to the building through a flexible tube at the upper side, and conditioned air is supplied from this duct or dirty air or the like is discharged to this duct.

Further, the above-mentioned ceiling portions 1A, 1B are provided with lighting fixtures of lighting equipment facing downward, and the lighting equipment is supplied with electricity from the building side by electric wires.

Therefore, when the ceiling surface is descending due to the elevation of the ceiling surface, it is possible to efficiently perform both air conditioning and lighting as in a normal office.

In the above description, expressions such as a hoist, a traveling girder, and a trolley are used, but other expressions having the same function may be used instead. That is, the above expression should be understood as a superordinate concept including means having equivalent functions. Similarly, instead of a hoist, a hydraulic cylinder, a screw mechanism, or the like may be used as the ceiling elevating means.

(Effects) Since the present invention has the above-described configuration, when a heavy load is transported, it can be easily transported by exposing the traveling crane body below the ceiling surface, and the traveling crane can also be transported. By storing the main body behind the ceiling,
It can be used as a building with a good environment.

Therefore, even in the case of brain labor, unlike the conventional factory, it is possible to concentrate in a good environment.

In particular, mental work is required for brain work, but when the ceiling surface is lowered despite having a traveling crane, the ceiling surface becomes lower and mental stability is obtained.
