DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The disclosed technology belongs to the structural technology field of an apparatus for painting the side surface of a high-rise building such as an oil storage tank of a steel structure.

<Summary of the gist> The invention of this application is an apparatus for painting the outer surface of a high-rise building made of iron such as a flat-bottomed cylindrical oil storage tank for regular or irregular maintenance. The high-rise building is mounted on a turret-type guidebost mounted on the side of the horizontally movable trolley mounted on the wind girder at the top of the high-rise building so as to be substantially close to the foundation at the bottom. This invention relates to a coating device for a high-rise building, which is provided with a support roller for the outer surface of the building, and is provided with a gondola having a coating device body such as a robot that can move up and down along a guide post. A device such as a roller supporting the foundation of a high-rise building is provided integrally with the lower part of the post, and a supporting force imparting device is further provided to apply an upward reaction force to the guide post on the movable support. This invention relates to a painting device for high-rise buildings.

<Prior Art> As is well known, some structures include high-rise buildings such as oil storage tanks, silos, and steel towers that are constructed from materials such as steel due to their design, cost, function, etc. Although there are different shapes, there are high-rise buildings in which a predetermined number of wind guard ribs are integrally installed externally in a ring shape in terms of wind pressure function and the like.

Naturally, in order to maintain the durability of these high-rise buildings, not only during construction, but also during operation, regular and irregular maintenance is required, especially on the external surfaces. It is supposed to be painted.

Since most of the painting of these types of high-rise buildings is done at high places, the work has generally been carried out using scaffolding or crane trucks in order to improve safety, efficiency, and finish accuracy. .

However, for example, in the case of oil storage tanks, service tanks and storage tanks are becoming larger due to the recent increase in energy demand and demand from the chemical industry.
There are some large-scale wind girders with a height of around 30 m and a diameter of around 100 m, and naturally many large-sized wind girders are being installed. There was a problem like this.

That is, as mentioned above, when working on high-rise buildings, if scaffolding is erected, the preliminary work period is long, and the safety of the preliminary work itself is not always sufficient, which is a disadvantage, and the working environment is also insufficient. Another problem is that the finishing accuracy is not always satisfactory.

Further, when work is carried out by suspending the gondola using a crane or the like, there is also the disadvantage that it is difficult to manage and control the gondola, resulting in high costs.

There has been a strong desire to develop a technology that would allow automation technology to be introduced into painting work for such large, high-rise buildings, allowing painting work to be carried out safely and at high openings in a good working environment.

In response to this, an automatic coating device 1 as shown in FIG. A wind girder at the top of a large oil storage tank 4 as a high-rise building having wind girders 3, 3...
A turret-type guide post 6 is suspended from a self-propelled horizontally movable trolley 5 set at the storage tank 4.
In order to prevent lateral wobbling, a support roller 7 is provided at the lower end facing inward, and a gondola 9.9' is provided which is moved up and down along the guide post 6 via a wire by an air motor 8 or the like provided at the bottom. For example, the coating device main body 11 for the side surface of a one-pot type, etc., and the coating device main body 11' for the wind girder 3 are equipped, and the coating device main body 11' is equipped for the wind girder 3 as shown in FIGS. 7 and 8. , technology for automatically painting the top and back surfaces of such devices has come into practical use.

<Problems to be Solved by the Invention> As mentioned above, these oil storage tanks 4 as high-rise 111' 3W products have recently been made larger due to the demand for storage M, etc. -Goo 3, especially the top wind girder 3' also made a noise of 1 person,
Its width has become overhanging, well over 1m.

Naturally, in order to paint the outer surface of the side plate 10 of the oil storage tank 4, which is becoming larger, and the wind girders 3, 3', the coating equipment 1 must also be enlarged, and it will become heavier and heavier. Most of the weight of the large and heavy coating device 1 is maintained on the wind girder 3' at the top, and the lateral couple at the bottom is supported by the side plates 10. girder
The large amount of overhang of the tank 3' leads to insufficient strength, and the strength of the tank side wall 10 also becomes insufficient, resulting in a drawback.

Furthermore, the wind girder 3' at the top of the oil storage tank of the actual structure is not formed in a perfect circle shape, but due to the construction h1 and site construction reasons, it is polygonal, and each side is straight. Therefore, the connection points between them are turning points, which makes it difficult to move the large and heavy coating device 1 around the side of the oil storage tank 4 smoothly. It started coming.

<Purpose of the Invention> The purpose of the invention of this application is to develop a technical solution to solve the problems of large and heavy painting equipment that paints the sides of high-rise buildings such as oil storage tanks, which are becoming larger based on the above-mentioned prior art. The challenge is to reduce the load on the wind girders and side panels of high-rise buildings, even though they will inevitably become larger due to the increase in the size of the high-rise soup stock, and will become heavier due to the installation of various automatic devices. Therefore, the load on high-rise buildings is effectively reduced without requiring the collapse shrine to increase the strength of high-rise buildings, and the benefits of automation are promoted, allowing painting work around high-rise buildings to be carried out safely and smoothly. In this way, it is an object of the present invention to provide a painting device for high-rise buildings in the construction industry.

<Means/effects for solving the problem> In accordance with the above-mentioned purpose, the structure of the invention of this application, which is summarized in the claims of the above-mentioned patent, is to solve the above-mentioned problem. When painting the outside surface of the wind girder and the wind girder, a horizontal movable trolley is set on the wind girder at the top of the wind girder. A device such as the above is installed to take an upward reaction force to the foundation and reduce the gravity of the coating equipment without applying an excessive load to the wind girder at the top. The upward reaction force is controlled to be slightly smaller than the weight of the painting equipment depending on the conditions, minimizing the cart applied to the wind girder, and synchronizing the lateral moving cart and the movable support. During this time, the gondola moves around the high-rise building in synchronization with the guide boss, and the gondola lowers its back in a predetermined position, and the coating equipment, such as a robot, is installed on the side of the high-rise building or the window. The predetermined painting work on the girder can be carried out freely and automatically and efficiently, and at the same time, the movable support absorbs the unevenness of the foundation and smoothly moves the painting equipment around the high-rise building. In this process, as the coating equipment increases in size and weight, it is necessary to avoid applying unreasonable loads to the wind girders and side panels of the high-rise building equipment, thereby affecting the functions of the high-rise building. This is a modification of technical means that prevents this from occurring.

Practical Example-Structure> Next, one embodiment of the invention of this application will be described as follows based on FIGS. 1 to 5. Note that the same parts as in FIGS. 6 to 8 will be described using the same reference numerals.

The illustrated embodiment relates to painting a large oil storage tank as a high-rise building, and is shown in FIGS. 1 to 3. In the J-embodiment, 1' is a coating device which is constructed on base RA2 and has wind girders 3, 3, . . . , 3' in its tenth half. The purpose is to paint the outer surface of the side plate 10 of a high-rise building 4, and a self-propelled horizontally movable trolley 5 set on the wind girder 3' at the top in the same manner as in the conventional manner is equipped with turret-type guide posts 1 to 3. 6 is mounted in a suspended manner with its lower end close to the foundation 2, and a movable support 12 is integrally provided at the lower end of the support J,! j The D-ra 15 comes into contact with the %@2 and takes an upward reaction force, so that the entire gravity of the coating device 1' is not applied to the lateral moving cart 5, but instead is applied to the wind girder 3'. A light load, which is calculated by subtracting the upwardly tilted horn from the coating device 1', is applied to the wind girder 3'.
It is designed to be able to support it with sufficient strength.

The guide post 6 is provided with a support roller 7 at its lower end in order to avoid applying an impactful load to the oil storage tank 4, so that the guide post 6 always maintains a constant hanging position. The gondola 9.9' installed on the kite boss 6 so as to be able to be raised and lowered is stopped at a predetermined position via a wire 18 by a winch 17 which is rotated by an air motor 8 provided at the lower part of the kite boss 1.
0 to the gondola 9,
Further, a coating device main body 11' for the wintogargou 3.3... is mounted on the gondola 9'.

And for gondola 9.9', guide post 1-6
It is also possible to allow a lateral movement within a predetermined stroke.

As shown in FIG. 4.5, in the movable support 12, a damper spring 13 whose elastic force can be adjusted is attached to a bracket 14 fixed downwardly at the lower end of the guide post 6.
is provided so that the upward reaction force of the support roller 15 can be adjusted freely, and the support roller 15, which is slightly movable up and down with respect to the guide post 1-0 via the damper spring 13, is Air motor 1 installed in
Rotating torque is applied by 6 to allow the coating device 1' to self-propel in synchronization with the lateral moving trolley 5, so that the coating device 1' can self-propel in circles while always maintaining the same attitude with respect to the side plate 10. has been done.

Furthermore, since the wind girder 3 has its upper and lower surfaces, the robot-type painting device main body 11 installed on the gondola 9'
As shown in FIG. 2.3, the wind girder 3 is arranged parallel to and perpendicular to the side plate 10, so that the upper and lower surfaces of the wind girder 3 can be painted.

It should be noted that the coating device 1' is disassembled and stored as appropriate when no coating work is to be performed.

<Embodiment - Effects> 1) In the E configuration, when painting the outer surface of the oil storage tank 4 for regular or irregular maintenance during construction or operation, 1%'XM neck 1 ', as shown in Figure 1.2, stand upright on the outside of the side plate 10 of the oil storage tank 4, and attach the wind girder at the top.
3', a movable support 12 is installed on the NIT 12, and the guide post 6 is mounted. Therefore, as described above, the total weight of the coating device 1' is , are not all maintained by the movable support 12, but the cart obtained by subtracting the upward reaction force from the movable support 12 from the own vehicle is transferred to the lateral movable cart 5, that is, the wind girder 3' at the top. Therefore, the wind girder 3' is not of a robust structure to maintain the metal skewer of the coating device 1'.

Thus, the spring force of the damper spring 13 of the movable support body 12 is adjusted in advance so that a load of 1q is applied to the lateral moving truck 5 supported by the wind girder 3' when moving the car.

Then, the air motor 8 is started to raise and lower the gondola 9.9' to a predetermined position, and the outer surface of the lower half side plate 10 is coated with the coating device main body 11 through the lateral movement of the lateral moving trolley 5. Moreover, the robot painting device main body 11' maintains its posture appropriately under robot l-control and paints the outer surfaces of the wind guards 3, 3, . . . and the side plates 10 between them. The air motor 16 of the movable support 12 and the
The air motor in the groove moving platform 5 is operated, and the coating device 1' always maintains the same posture around the oil storage tank 4 and travels around the oil storage tank 4, so that the coating device main body 11, 11' moves vertically and horizontally in a diagonal pattern. This allows for thorough painting work on all sides.

During this period, even if some wind blows, the coating device 1' will not be separated from the side plate 10 by the support rollers 7, nor will any impact load be applied to the side plate 10 by applying a pressing force or the like.

Therefore, as a result, the strength of the side plate 10 of the oil storage tank 4 is not particularly increased, and the strength against the hydraulic pressure and seismic force of the stored oil is sufficient.

In this way, once the coating is completed on the outside surface of the oil storage tank 4, the coating device 1' is appropriately folded and stored, and the next coating is carried out again. Be prepared.

It goes without saying that the embodiments of the invention of this application are not limited to the above-mentioned embodiments. For example, the movable support may be replaced with a crawler, or the movable support may be replaced with a crawler. On the other hand, it is possible to provide a circumferential rail on the foundation, provide multiple joints on the guide post itself to make it expandable and retractable, or install a hydraulic damper or the like as a support force imparting device on the movable support to reduce the upward reaction force. It is possible to make it adjustable.

Even if there are irregularities in the circumferential direction of the foundation 2 when the coating device 1' runs around, the damper spring 13 absorbs the rise and fall, and the horizontal moving cart 5 and the wind girder 3
′ is prevented from increasing the applied load.

The high-rise buildings to which this method is applied are not limited to oil storage tanks, but can also be applied to 1-layer buildings, steel towers, etc.

<Effects of the Invention> As described above, according to the invention of this application, when painting the operating port 4 on the outer surface of a high-rise building such as a large oil storage tank, a painting device such as a robot, a gondola, or Even if the coating equipment with the guide boss equipped with the air motor shade becomes large and quick, the entire load is applied to the wind girder through the horizontal moving cart that is attached to the wind girder butt 1 at the top. By providing a movable support that is supported against the foundation at the lower end of the guide post, a slight load is applied to the wind girder at the top by removing the upward reaction force from the weight. In order to avoid this, the wind girder's overhang and strength must be sufficient to counter the wind force, and the coating equipment itself does not have to be tied in any way even if it becomes large and heavy, and the side plate is also movable at the lower end of the guide post. Because there is a support, it receives an excessive support reaction force (in order to play against the stress, the strength must be increased as well, and the excellent effect of bending in the original structure of high-rise buildings such as tanks). be done.

Therefore, even if the painting equipment becomes large and heavy, there is no need for any restrictions that restrict automation, so automation can be freely implemented, and it is an excellent system that is highly safe and increases work efficiency. The effect is Qin.

By making the movable support self-propelled, it can run around in synchronization with the horizontally movable cart set on the wind girder, so the coating equipment always remains in the same position. It can be driven easily, and from that point of view, the 92M can be painted in one way, resulting in a highly accurate painting finish and improved reliability.

By equipping the movable support with a support force imparting device, it is possible to adjust the upward reaction force using the strip 1, and it is also possible to absorb uneven surfaces in the circumferential direction of the foundation when traveling in circles. The excellent effect of Qin.
