When the upper and lower rotary rods of the central rotary rod 920 rotate in the first direction by the central rotary motor 923, the upper and lower nut coupling portions 924 and 925 coupled thereto are as shown in FIG. Each moves to approach each other, so that the upper and lower horizontal bars 921 and 922 also move to approach each other. The upper horizontal bar 921 is coupled to all of the second ends of the plurality of upper sloped beams 913, and the lower horizontal rod 922 is coupled to all of the second ends of the plurality of lower sloped beams 914. 921 is lowered and the lower horizontal bar 922 is raised to move to approach each other, along the upper and lower vertical rails (915, 916) such that the second ends of the upper and lower inclined beams 913, 914 also approach each other. As a result, the rear end portions of the upper horizontal stretchable beam 911 and the lower horizontal stretchable beam 912 move toward the outer wall so that the work module 800 moves toward the outer wall.

On the contrary, when the upper and lower rotating rods of the central rotating rod 920 rotate in the second direction by the central rotating motor 923, the upper and lower nut coupling parts 924 and 925 coupled thereto are shown in FIG. 8. As they are moved away from each other, the upper and lower horizontal bars (921, 922) are also far from each other. That is, the upper nut coupling part 924 is raised to raise the upper horizontal bar 921, and at the same time, the lower nut coupling part 925 and the lower horizontal bar 922 are lowered and move away from each other. Accordingly, the second end of the upper inclined beam 913 coupled to the upper horizontal rod 921 is raised upward, and at the same time, the second end of the lower inclined beam 914 coupled to the lower horizontal rod 922 is lowered downward. They are separated from each other. As such, the second ends of the upper and lower inclined beams 913 and 914 coupled to the upper and lower horizontal bars 921 and 922 also move vertically along the upper and lower vertical rails 915 and 916 so as to move away from each other. As a result, the work module 800 coupled to the rear ends of the upper horizontal stretchable beam 911 and the lower horizontal stretchable beam 912 is pulled in the direction of the receiving frame 712 to retreat.

FIG. 10 is a schematic perspective view showing a state in which the work module 800 is retracted from the outer wall in the outer wall working apparatus 600 of the present invention shown in FIG. 2. In the present invention, by the advancing unit having the above-described configuration, the work module 800 is advanced toward the outer wall as shown in FIG. 2 in accordance with the state of the outer wall, and the situation of the outer wall work, or conversely, as shown in FIG. The module 800 is pulled toward the receiving frame 712 to retreat, so that the outer wall working device 600 can perform the outer wall work in the state positioned at the optimum interval in the front and rear from the outer wall 900, As a result, the exterior wall work is very smooth and efficient. In particular, when a jaw (protrusion jaw) protruding from the outer wall or a window in the position recessed from the outer wall is present, by advancing the working module 800 in the manner described above to go over the protruding jaw or enter the depression to perform the outer wall work It can be done. Therefore, according to the present invention, even if any uneven obstacles such as high protrusions or depressions exist on the outer wall, the outer wall work can be performed in a state where the working module 800 is disposed at the optimum interval. Of course, even in the case of the external wall work such as cleaning that needs to be in close contact with the outer wall in the present invention through the advancing configuration of the work module 800 as described above, the required part of the work module 800 in the optimum state to approach or close to the outer wall The state can be stably maintained, thereby maximizing the efficiency of exterior wall work.

In the present invention, the drive module 700 may be provided with a counterweight for making the outer wall working device 600 can achieve a balanced state of the weight without tilting. The counterweight may consist of a left and right balance counterweight 770 for adjusting the horizontal balance in the lateral direction, and a front and rear balance counterweight 771 for adjusting the horizontal balance in the front and rear directions. Left and right adjustment counterweight 770 may be installed on the lower side of the storage frame 712, as illustrated in the figure, the horizontally extending balancing rod is installed by hanging below the storage frame 701 and on both sides of the balance bar Each of the balance weights is mounted to adjust the balance in the cross direction while moving the position of the balance weight 775 fitted to the balance bar 774 in the cross direction. Front and rear adjustment counterweight 771 is similarly installed by hanging the balance bar extending in the front and rear direction under the storage frame 712, and the balance weight is mounted on the balance bar to adjust the position of the balance weight fitted to the balance bar. The balance in the front-rear direction is adjusted while moving in the front-rear direction. Therefore, the outer wall work device 600 can maintain a stable equilibrium in the course of the outer wall work. Particularly, as described above, when the work module 800 is advanced toward the outer wall, the overall weight balance of the outer wall work device 600 is adjusted by adjusting the position of the balance weight of the front and rear balance counterweight 771 forward and backward. The advantage of being able to grab and thus maintaining a very stable state is exerted.

The outer wall working apparatus 600 of the present invention is provided with a propeller 750 that generates wind by rotating the driving module 700 toward the outer wall by generating wind by rotation. Propeller 750 may be provided in plurality, as shown in the embodiment shown in the figure, it is installed coupled to the receiving frame 712, is fixedly installed in the required position of the top, bottom, left and right outside the storage frame 712. 11 is a schematic perspective view showing one example of the propeller 750. As illustrated in the figure, the propeller 750 may have a cylindrical shroud ring 760 to concentrate thrust towards the rear outer wall, the shaft passing through the cross-sectional center of the shroud ring 760. The support 761 may be installed in the shroud ring 760 in the radial direction, and the rotary shaft may be installed to be orthogonal to the shaft support 761, and the rotary blade 762 may be coupled to the rotary shaft. At this time, in order to increase the rearward thrust, it is preferable to have the form of a coaxial rotary blade equipped with two rotary blades 762 on one rotary shaft as illustrated in FIG. However, the propeller 750 provided in the present invention is not necessarily limited to one having a coaxial rotating blade as illustrated in FIG. 11, and may have one rotating blade as illustrated in other drawings besides FIG. 11. In the embodiment illustrated in the drawings, the member number 763 is a drive motor 763 provided on the rotating shaft 764 to rotate the rotary blade 762. On the other hand, when a circular, elliptical or polygonal cross-section pipe member having hollows is used as the shaft support 761, a power line (not shown) is disposed in the hollow of the shaft support 761 to drive the motor 763. Can be connected to Although not explicitly expressed in the drawings, the electric power for driving the propeller motor in the present invention may be supplied in a wired manner, and thus, the thrust may be continuously generated by the propeller during stable driving and external wall work of the driving motor 763. Done. That is, the operation of the propeller 750 is discontinued due to the discharge of the battery during the outer wall work, thereby the effect that can be prevented from being stopped by the source is exerted. Of course, a signal line can also be arranged in the hollow of the shaft support 761.

12 (a), (b), (c) and (d) describe a state in which the outer wall working device 600 is in close contact with the wall surface of the outer wall by pushing the retreating unit and the propeller 750 in the outer wall direction, respectively. In order to see the outer wall work device 600 in a transverse direction, a schematic conceptual view in the form of a side view is shown. 12 (a), (b), (c) and (d) of the outer wall working device 600 is shown as a small circle for convenience, the work module 800 provided in the outer wall working device 600 is a small circle. It is shown in the shape of a T-shaped stick (the English capital letter T lying sideways) attached to the back of the. In Figure 12 (a), (b), (c) and (d) W represents the total weight of the outer wall working device 600.

As described above, if there is a large obstacle such as a protruding jaw on the outer wall while performing the outer wall work, the outer wall working device 600 should be spaced apart from the outer wall so that the outer wall working device 600 can move up and down the obstacle. 12 (a) is vertical by placing a large obstacle such as a protruding jaw on the outer wall 600 so that the outer wall working device 600 is spaced apart from the outer wall 600 so as to have a larger distance than the protruding length of the obstacle. When moving, the work module 600 shows a state made not to catch the obstacle. In FIG. 12A, U is a front and rear gap between the wire 3 hanging from the outer wall working device 600 and the outer wall 900, when the operation of the retraction unit and the thrust of the propeller 750 do not work. It is a gap between the outer wall working device 600 and the outer wall 900.

As described above, in the outer wall working device 600 of the present invention, the working module itself may have a configuration capable of advancing and retreating within a predetermined distance toward the outer wall. In this case, through the rear advancing operation of the retreating unit as necessary. Work module 800 may be located at the optimum interval (S). 12 (b) shows that the work module 800 is moved to the outer wall direction by the operation of the retreat unit in a state where the outer wall working device 600 is located in front of the outer wall 900, so that the work module 800 has an optimum interval ( It shows the state that is placed at the position of S). Of course, even when the outer wall has a depression, the operation module 800 may approach the outer wall 900 such that the gap between the working module 800 and the outer wall 900 becomes an optimum interval S by the operation of the retreat unit. . Here, the optimum spacing S is a gap between the outer wall working device 600 and the outer wall 900 when it is suitable to perform the outer wall work. Of course, if there are no obstacles such as protrusions and depressions on the outer wall, the outer wall work is performed while the outer wall working device 600 is raised and lowered to maintain the optimum distance S in front of the outer wall from the beginning. .

On the other hand, in the present invention may maintain the optimum interval (S) through the thrust generation of the propeller (750). 12 (c) is a state in which the working module 800 is disposed at the optimum interval S by generating a thrust by the propeller 750 in the state where the outer wall working device 600 is located in front of the outer wall 900. Is shown.

As described above, the work module 800 may be disposed at the optimum interval S using only one of the operation of the advance unit and the thrust generation of the propeller 750, but both may be used if necessary. . 12 (d) shows a state in which the optimum interval S is zero by using both the operation of the advance unit and the thrust generation of the propeller 750. For reference, as shown in (a) to (c) of FIG. 12, the work module 800 may be spaced apart from the outer wall 900 by a predetermined length as an optimum interval S, depending on the type of outer wall work. As shown in FIG. 12D, the rear end of the work module 800 is in close contact with the outer wall 900 such that a horizontal distance (interval) between the rear end of the work module 800 and the outer wall 900 is zero (zero). ) May be a state of the optimum interval (S).

In the case of the cleaning operation, the outer wall working device 600 is moved to the outer wall 900 by the operation of the propeller 750 while the rear end of the working module 800 approaches or contacts the outer wall 900 through the rear entry and exit operation of the retreat module. By generating a thrust pushing toward the working module 800, it is possible to apply a close contact pressure and accordingly maintains a constant adhesion between the rotary cleaning drum and the outer wall such as a brush provided in the working module at all times to perform the cleaning operation efficiently Effect is exerted. Of course, even if the work module is not for cleaning but for paint painting or other exterior wall work, only one of the above-mentioned operation of the retraction unit and thrust operation by the propeller 750 or both may be used. By using it, it is possible to maintain a constant distance to the degree of adhesion between the work module and the outer wall, the work efficiency is further improved accordingly.

On the other hand, as the outer wall work device 600 is lowered, the length of the wire (3) hanging it is increased, and the length of the various work lines are also increased to increase the weight of the entire outer wall work device 600, the outer wall work The thrust of the propeller 750 required for bringing the device 600 into close contact with the outer wall surface is also varied. Therefore, in order to constantly push the outer wall work device 600 to the optimal close contact by applying a thrust, it is necessary to control the operation of the propeller 750 in consideration of the total weight increase according to the raising and lowering of the outer wall work device 600. In particular, when a plurality of propellers 750 are respectively installed on the top, bottom, left and right sides of the storage frame 712, it is necessary to control the operation of the propeller 750 continuously and balance, respectively.

12 (a), (b), (c) and (d), the propeller 750 should be exerted to take into account the length of the vertical wire 3 and to always have a constant adhesion toward the outer wall. Necessary thrust "is a function of the vertical distance y from the upper end of the wire 3 to the outer wall working apparatus 600, and the following equation 1 holds.

는 와이어(3)의 상단으로부터 외벽작업장치(600)까지의 수직거리가 y일 때 외벽작업장치(600)를 외벽 쪽으로 항상 일정한 밀착력(P)으로 밀어주기 위해 프로펠러(750)가 발휘해야 할 필요 추력이며, W는 외벽작업장치(600)의 총중량이고,

는 와이어(3)와 외벽작업에 필요한 각종 작업선(전선, 세척수 호스, 고압공기 호스 등)을 합한 모든 선 전체의 단위길이 당 중량이고, s는 외벽과 외벽작업장치(600) 사이의 수평간격이다. 따라서 위의 수학식 1을 이용하여 프로펠러(750)의 작동을 제어함으로써 필요추력을 발생시킬 수 있다. 물론 외벽작업이 완료되어 외벽작업장치(600)를 상향 이동시킬 때, 그리고 외벽작업장치(600)가 외벽에 존재하는 장애물을 통과하여 승하강할 때에는 프로펠러(750)의 작동을 정지시킨다. In Equation 1 above

When the vertical distance from the top of the wire (3) to the outer wall working device 600 is y, the propeller 750 needs to be exerted to always push the outer wall working device 600 toward the outer wall with a constant adhesion force (P). Thrust, W is the total weight of the outer wall working device 600,

Is the weight per unit length of all wires combined with wires (3) and various work lines (wires, washing water hoses, high pressure air hoses, etc.) necessary for external wall work, and s is a horizontal gap between the external wall and the external wall working device 600. to be. Therefore, it is possible to generate the required thrust by controlling the operation of the propeller 750 using the above equation (1). Of course, when the outer wall work is completed to move the outer wall work device 600 upward, and when the outer wall work device 600 ascends and descends through the obstacle present in the outer wall, the operation of the propeller 750 is stopped.

FIG. 13 is a schematic perspective view showing an example of a work module 800 for cleaning the outer wall separated from the drive module 700, and FIG. 14 is a schematic lateral direction of the work module 800 of FIG. 13. A side view is shown. Figures 15 (a) and 15 (b) show a schematic plan view of the work module 800 of Figure 13, respectively, Figure 15 (a) is a top down view, Figure 15 (b) is I looked up from the bottom up. FIG. 16 is a schematic perspective view showing only the washing water spraying device 820 separately provided to the work module 800 of FIG. 13 to spray washing water. Here, the work module 800 is not only to clean the wall surface of the outer wall, but also to clean the window provided on the outer wall, the term "outer wall" in connection with the work module 800 for performing the cleaning operation as the outer wall work is the window ( Glass window).

 As shown in the drawings, the work module 800 for the cleaning operation includes a module frame 815 disposed toward the outer wall, and a cylinder extending laterally, and rotatably installed on the module frame 815 and being rotated. It comprises a rotary cleaning drum 810 to shake off or wipe off the foreign matter by the outer wall. In the embodiment illustrated in the drawings, the module frame 815 is composed of a rectangular frame member, the square plane is disposed to face the outer wall, the rear side of the module frame 815 is formed of a horizontally extending cylindrical Rotary cleaning drum 810 is provided. The rotary cleaning drum 810 may be in the form of a soft brush made of fusing or microfiber, which is easy to remove foreign substances, and cleans the outer wall by brushing off or wiping off foreign substances on the outer wall by rotation. Although one rotary cleaning drum 810 is illustrated in the embodiment of the figure, the rotary cleaning drum 810 may be provided in plural numbers, and in particular, the plurality of rotary cleaning drums 810 may be disposed thereon. It may be provided in parallel down. If necessary, a washing water spraying device 820 for spraying the washing water on the outer wall may be further provided in the module frame 815. The washing water spraying device 820 may be installed below the rotating cleaning drum 810 so as to spray the washing water onto the outer wall before removing the foreign matter by the rotating cleaning drum 810. As shown in FIG. 16, the washing water spreading apparatus 820 may include a fan-shaped spray hole 821 in which the width in the horizontal direction increases toward the rear side so that the washing water may be evenly sprayed in a wide range in the lateral direction. As the washing water is sprayed to the outer wall from the washing water spraying device 820, foreign substances such as dust existing on the outer wall are firstly removed and water is supplied to the outer wall, thereby providing two of the foreign substances by the subsequent rotary cleaning drum 810. Tea removal is more smooth and efficient.

If necessary, the washing water spraying device 820 may be further provided with a high pressure air mixing device 843 for mixing the high pressure air and water to spray the washing water at a high pressure. The high pressure air mixing device 843 receives the high pressure air from the high pressure air hose and sprays it toward the outer wall. At this time, the washing water supplied through the water supply hose connected to the high pressure air mixing device 843 is strongly sucked during the injection process of the high pressure air and mixed with the high pressure air to be sprayed in the form of high pressure fine water. In particular, as shown in the drawings may be further provided with a configuration for spraying the washing water in the form of high-pressure particulate water disturbed like a tornado. It may be further provided with an additional configuration that can be sprayed to the outer wall in the form of a strong flow in the form of whirlwind or tornado in high pressure fine water. Specifically, as shown in the drawing, a nozzle-shaped nozzle bar 822 is provided inside the fan-shaped injection hole 821 in an extended form toward the outer wall, and the particulate water inside the nozzle bar 822. Injection pipe 828 is located. The nozzle bar 822 is connected to the high pressure air mixing device 843, and high pressure air is discharged around the fine water injection pipe 828. A weight 823 is provided at the nozzle bar 822. When the nozzle bar 822 is provided in such a form, the high pressure fine water generated from the high pressure air mixing device 834 is spouted from the nozzle bar 822, and the nozzle bar 822 is caused by the pressure of the fine water. In the fan-shaped injection hole 821, the oscillating motion, so that the fine water is tornado-like tornado is injected toward the outer wall. That is, the high pressure fine water injected while the nozzle bar 822 oscillates is guided in the outer wall direction by the fan-shaped injection port 821 and is scattered on the cleaning part of the outer wall. As such, when the washing water is injected into the tornado-type perturbed high-pressure fine water through the nozzle bar 822 oscillating in the fan-shaped nozzle 821 in the washing water spreading device, a very small amount of water Consumption can be carried out effectively while cleaning, bar is a very useful effect that can not only save water but also minimize the discharge of contaminated water by cleaning. Washing water spraying device 820 may be provided with one or a plurality.

The rear side of the module frame 815 may be provided with a wheel 830. Wheels 830 may be provided in plurality, in particular, as shown in the figure may be provided in each of the four rear side edges of the module frame 815. The wheel 830 serves to help the work module 800 move along the outer wall and also function as a shock absorber to protect the outer wall. It is also preferable to use a low pressure pneumatic tire as the wheel 830. In the case of a low pressure pneumatic tire, since the pressure is low, the wheel can be easily changed according to the shape of the obstacle, so that the window during the cleaning operation Small obstacles such as joints can be easily crossed so that the outer wall work such as cleaning can be performed while moving along the outer wall very easily and smoothly. In this way, while working over the small obstacles such as window joints through the wheels 830, when encountering large obstacles such as protrusions or depressions, the work module is moved forward and backward by the operation of the retreat unit to proceed with the exterior wall work. do.

In particular, when using low-pressure pneumatic tires, the largely traded flexible wheels are pressed and pressed against the glass surface by propeller thrust, so as to be caught like a sucker on the glass surface. There is an advantage that effectively reduces.

Further, in mounting the wheel 830, by using a shock absorber (shock absorber) using a spring and an attenuator to install on the rear side of the module frame 815, the wheel 830 to block the obstacles It is also desirable to pass smoothly with minimal impact when passing.

FIG. 17 is a schematic perspective view corresponding to FIG. 13 showing another embodiment of the work module 800 for cleaning the outer wall. It can often happen that the foreign matter is not simply cleaned by simply applying pressure and spraying the wash water and wiping the surface with the rotary cleaning drum 810, such as in the case of foreign matter that is difficult to remove, such as dust, on the outer wall. have. For this case, as shown in FIG. 17, if necessary, the work module 800 may have a configuration capable of spraying the washing water in the form of heated steam, that is, steam. In detail, in the case of the work module 800 illustrated in FIG. 17, the fluid supply pipe 861 extends in the lateral direction at the rear side of the module frame 815. The fluid injection nozzle part 860 is formed in the fluid supply pipe 861 toward the outer wall. In particular, in the embodiment shown in the drawing, the fluid injection nozzle part 860 is formed with a plurality of intervals. Therefore, when the supplied washing water is made in the form of steam and supplied to the fluid supply pipe 861, it is sprayed to the outer wall through the fluid injection nozzle unit 860. When steam is sprayed on the outer wall, it is preferable to use the rotary cleaning drum 810 provided with a hard brush on the surface of which the outer wall can be strongly washed. When the fluid supply pipe 861 and the fluid injection nozzle unit 860 are further installed in the work module 800 and the steam is sprayed on the outer wall using the same, even if the outer wall is contaminated with foreign matter such as dust, etc., The advantage is that it can be removed and cleaned very effectively.

The configuration of the fluid supply pipe 861 having the fluid injection nozzle unit 860 described above can be used to inject paint in addition to spraying steam. When the rotary cleaning drum is removed from the work module 800 shown in FIG. 17 and the paint is supplied to the fluid supply pipe 861 to spray paint paint on the outer wall through the fluid spray nozzle part 860, the work module 800 is to function as a painting operation module to perform painting as a substantially outer wall work. FIG. 18 is a schematic perspective view of a working module 800 having a plurality of fluid supply pipes 861 as another embodiment of the working module 800. As illustrated in FIG. In case of working downward with a plurality of 861, the primer for spraying is sprayed by the fluid supply pipe and the fluid ejection nozzle unit located at the lower side, and the fluid supply pipe and the fluid ejection nozzle unit located at the upper side are used. The work module 800 may be configured by spraying paint paint, and thus, the work module 800 may be efficiently configured by configuring the work module according to various paint methods.

In such a configuration, the existing work module can be removed and a new work module can be assembled and assembled to the upper and lower horizontal stretching beams 912, so that the work module 800 of the required shape can be replaced and installed in accordance with the exterior wall work. Therefore, it is possible to create a state optimized for exterior wall work. Furthermore, in such a configuration in which the work module 800 can be easily replaced and assembled to the driving module 700, repair or management work is performed in a state in which the work module 800 and the driving module 700 are separated from each other. As a result, maintenance is also very easy.

As shown in the figure, the cable hanger 400 is formed of a ring-shaped member in which a hollow through which the ropeway cable 1 penetrates is formed, and a slit 490 cut and opened is formed at a lower portion thereof. Swing gate (410) for opening and closing is provided. In the exemplary embodiment shown in the drawing, a guide groove 412 through which the swing gate 410 is inserted and moved is formed at one outer surface of the cable hanger 400. A swing gate 410 is inserted into the guide groove 412. A compression spring 411 is built in the guide groove 412. When the holding box does not pass, the swing gate 410 is guided by the pressing force. 412, the swing gate 410 blocks the slit 490, so that the cable hanger 400 remains in a closed ring shape as shown in FIGS. 24 and 25, such that the ropeway cable 1 It penetrates through this cable hanger 400, and keeps it suspended safely.

When the holding box 2 has to pass through the cable hanger 400, the neck part 511 of the cable coupling part 510 provided in the holding box 2 pushes in the transverse direction while touching the swing gate 410. And as shown in FIGS. 26 and 27, the swing gate 410 is slid further into the guide groove 412 so that the slit 490 is opened, thereby coupling the cable provided in the holding box 2. As the neck portion 511 of the portion 510 passes through the slit 490, the holding box 2 is smoothly transversely horizontally along the ropeway cable 1 without being disturbed by the cable hanger 400. You can move. When the holding box 2 passes completely through the cable hanger 400, the compression spring 411 that was pressed as the swing gate 410 is pushed into the guide groove 412 exerts a restoring force, and accordingly, FIG. 24. As shown in the swing gate 410 is automatically slid again to close the slit 490 so that the ropeway cable 1 is again securely hung on the cable hanger 400.

When the neck portion 511 of the cable coupling portion 510 provided in the holding box 2 touches the swing gate 410 as described above, the swing gate 410 may be pushed into the guide groove 412 more smoothly. In order to ensure that, the chamfer 420 is inclined (inclined to about 45 degrees) at the end of the view point of the swing gate 410 to which the neck portion 511 first touches (see FIG. 23). As will be described later, in the cable coupling part 510 provided in the holding box 2, when the equilateral triangular inclined surface 520 of about 45 degrees is formed at the transverse edge of the neck part 511, the chamfering part 420 is formed. The inclined surface 520 of the neck portion 511 abuts to smoothly open the swing gate 410. The cable hanger 400 provided with the swing gate 410 is provided in plurality in the hanger connecting member 121. When the neck portion 511 is cut into a planar shape and its cross-sectional shape is seen, the front and rear portions of the neck portion 511 have an equilateral triangular shape. According to this configuration, the holding box may be moved forward or as needed. When the neck 511 easily pushes the inclined surface of the swing gate chamfer 420 formed on the cable hanger 400 to make the slit 490 open, the holding box is always held regardless of the forward and backward movement of the holding box. (2) can pass smoothly through the cable hanger (400).

As shown in FIG. 19, the holding box 2 suspended from the outer wall working device 600 is horizontally moved along the ropeway cable 1, and the ropeway cable 1 is suspended from the cable hanger 400. The cable hanger 400 may be an obstacle when the holding box 2 moves. However, as described above, the cable hanger 400 has an open slit 490 formed at a lower portion thereof, and is provided with a swing gate 410 for opening and closing the bar hanger. When the horizontal movement of the holding box 2 is unnecessary, When the swing gate 410 closes the slit 490 so that the ropeway cable 1 stably hangs on the cable hanger 400 while penetrating the cable hanger 400, the holding box 2 moves horizontally. The neck portion 511 of the cable coupling part 510 provided in the holding box 2 pushes the swing gate 410 to open the slit 490, so that the holding box 2 smoothly hangs the cable hanger ( It is possible to move horizontally past 400). That is, in the present invention, through the above configuration, the cable hanger 400 can be effectively prevented from hindering the movement of the holding box 2 is exhibited.

FIG. 28 is a schematic enlarged perspective view of the circle G portion of FIG. 1 showing the holding box 2 movably hanging on the ropeway cable 1 in the ropeway system 100. 29 (a) and 29 (b) show a schematic enlargement of the circle D portion of FIG. 28 showing a detailed configuration in which the cable coupling part 510 of the holding box 2 is suspended from the ropeway cable 1, respectively. A perspective view (FIG. 29A) and a schematic lateral front view (FIG. 29B) are shown, and FIG. 30 is a schematic cross-sectional view in the vertical direction according to the arrow YY in FIG. 29B. Is shown. FIG. 31 shows a schematic cross-sectional perspective view along line E-E of FIG. 29. FIG. 32 is a schematic partial perspective view illustrating a state in which the cable coupling part 510 enters the cable hanger 400 so that the holding box 2 passes through the cable hanger 400 in the direction of the arrow. 33A to 33D are schematic front views sequentially illustrating a process of approaching and entering a cable hanger 400 having a slope 430, respectively, by the cable coupler 510. For convenience, the configuration of the brake device described below is omitted in FIGS. 29 to 32, and only the ring portion of the through case 512 and the cable hanger 400 is illustrated in FIG. 33. In particular, the cable hanger 400 has a cross-sectional shape. Shown.

As shown in FIGS. 28 to 32, a cable coupling part 510 is provided at an upper portion of the holding box 2, and the cable coupling part 510 passes through the slit 490 of the cable hanger 400. It comprises a neck portion 511 made of a member having a thin thickness, and a through case 512 made of a tubular member through which the ropeway cable 1 penetrates integrally provided on the neck portion 511. do. Neck portion 511 in the embodiment shown in the Figure is made of a plate member, the inside of the through-case 512 is provided with a roller pulley (Roller Pulley) 513 to roll over the ropeway cable (1) It is. As described above, it is preferable to form a chamfer 420 at the end of the view portion of the swing gate 410 to which the cable coupling portion 510 of the holding box 2 first touches. It is preferable to form inclined surfaces 520 having equilateral triangular shapes on both sides of the transverse direction at both longitudinal edges of the neck portion 511 which are in contact with the chamfer 420. That is, as shown in FIG. 30, the inclined surfaces 520 are formed at both longitudinal edges of the neck portion 511. At this time, the inclination angle of the inclined surface 520 is preferably about 45 degrees. As such, when the chamfer 420 and the inclined surface 520 are formed, the inclined surface 520 of the neck portion 511 is chamfered when the cable coupling portion 510 passes through the slit 490 of the cable hanger 400. The slit 490 is opened by pushing the swing gate 410 very smoothly with 420. That is, in the present invention, when the cable coupling portion 510 of the holding box 2 touches the swing gate 410 of the cable hanger 400 and exerts a force in the transverse direction, the swing gate 410 slides vertically and guides. It is pushed into the groove 412 and thus the slit 490 is opened, forming a chamfer 420 in the swing gate 410 and correspondingly the transverse direction of the neck 511 in the cable coupling portion 510 When the inclined portion 520 is also formed at the edge, an advantageous effect of opening the swing gate 410 more smoothly is exerted.

In addition, as shown in FIGS. 28 to 32, the through case 512 of the cable coupling portion 510 is formed of a cylindrical member, and cuts inclined with a gentle slope at both transverse ends of the through case 512. It is preferable that the portion 531 is formed. That is, the cutout portion 531 is formed by cutting inclined downward by a predetermined distance from both transverse end portions of the through case 512 toward the center portion. At both ends of the through-case 512 above the cutout 531, a tapered portion 530 having a cylindrical cross-sectional size may be formed toward the longitudinal end. In the cable coupling part 510, the neck part 511 is integrally coupled to the through case 512. As illustrated in the drawing, the longitudinal length of the upper end of the neck part 511 is provided at both ends of the through case 512. Is shorter than the longitudinal length between cutouts 531. Accordingly, in the state where the neck portion 511 is coupled to the through case 512, a short cylindrical section 532 in which the neck portion 511 does not exist is formed in the through case 9512 at the rear of the cutout 531 in the longitudinal direction. It will exist. That is, the cutout portion 531 is formed by cutting down the inclined portion by a predetermined distance from both transverse ends of the through-case 512 to the center portion, and the neck portion does not exist immediately after the cutout portion 531 is finished. The non-short cylindrical section 532 is a through-case 512, the neck portion 511 starting with the cylindrical section 532 and then the equilateral triangular inclined surface 520 is coupled to the through-case 512.

Corresponding to the cutout portion 531, as shown in (a) to (d) of FIG. 33, an upper portion of the cable hanger 400 is located at the center of the inner side of the cable hanger 400 in the transverse both ends of the cable hanger 400. The slope portion 430 is formed of a downwardly inclined surface. The inclined angle of the slope portion 430 formed on the inner side surface of the cable hanger 400 is preferably the same as the angle of the cutout portion 531. According to this configuration, when the through case 512 enters the inside of the cable hanger 400, the cutout portion 531 of the through case 512 meets the slope portion 430 of the cable hanger 400, and the through case The effect of being able to smoothly cross the step (the height difference in the vertical direction) existing between the 512 and the cable hanger 400 is exerted.

As shown in (a) of FIG. 33, the ropeway cable 1 is suspended in the cable hanger 400, and the ropeway cable 1 passes through the inside of the through case 512 entering the cable hanger 400. 512 is located in the lower portion of the roller pulley 513 mounted inside, due to the weight of the holding box (2), the through case 512 is located below the cable hanger 400, thereby through A step occurs between the case 512 and the cable hanger 400. This step causes inconvenience to the through case 512 to enter the cable hanger 400. However, in the present invention, as described above, a cutout portion 531 is formed at both ends of the transverse case 512 inclined with a gentle slope, and the cutout portion 531 is formed at the center of the inner side of the cable hanger 400. By forming the slopes 430, each of which is inclined downward on both sides in the lateral direction so as to have an angle corresponding to the photograph, the through case 512 smoothly moves to the cable hanger 400 despite the presence of the step difference. Entering the holding box 2 has an advantage that can pass through the cable hanger 400 smoothly. Looking in detail, while the slit 490 is closed by the swing gate 410 of the cable hanger 400, while the through case 512 of the holding box 2 approaches the cable hanger 400, Firstly, the cutout 531 of the through case 512 enters the cable hanger 400. Since the cutout 531 is formed to have a gentle slope in the same way as the slope 430 inside the cable hanger 400, despite the step difference due to the height difference between the through case 512 and the cable hanger 400. And the cable hanger 400 as the through case 512 ascends along the slope portion 430 in a state in which the cutout portion 531 is in close contact with the slope portion 430 as shown in (b) to (d) of FIG. 33. ) Will go smoothly. That is, the cutout portion 531 of the through case 512 is to enter the cable hanger 400 easily and preferentially while overcoming the step. In particular, in the embodiment shown in the figure, the neck portion 511 is not yet present in the short cylindrical section 532 following the cutout 531 in the lower and longitudinal direction of the cutout 531 and thus such cutout. It is very natural that 531 enters the cable hanger 400.

The cable coupler 510 enters the cable hanger 400 a little further from the state shown in FIG. 33C, and the cutout 531 and the subsequent cylindrical section 532 are connected to the cable hanger 400. After fully entering, the inclined surface 520 formed at the longitudinal edge of the neck portion 511 touches the swing gate 410. At this time, as described above, the inclined surface 520 formed on the neck portion 511 meets the chamfer 420 of the swing gate 410, and applies a force to push the swing gate 410, and accordingly, the swing gate 410. Is pushed into the guide groove 412 to open the slit 490. Subsequently, the neck portion 511 of the cable coupler 510 passes through the opened slit 490 as shown in FIG. 33 (d), so that the holding box 2 is free of any cable hanger 400. They move horizontally without any problems. In the present invention by the above process, the process of passing the holding box 2 through the cable hanger 400 is very easy and naturally proceeds.

While the outer wall work device 600 moves vertically in the vertical direction, and the outer wall work on the outer wall is performed by the outer wall work device 600, the holding box 2 should be stopped on the ropeway cable 1. do. It is also possible to configure the holding box 2 so that the holding box 2 can run and stop itself by installing an automatic driving means such as a motor in the holding box 2, but by connecting the holding box pull line to the holding box 2 in the transverse direction When the holding box 2 is moved in a pulling manner, a brake device for stopping the holding box 2 on the ropeway cable 1 should be provided in the holding box 2. 34 and 35 show an enlarged schematic perspective view of part D of FIG. 28 with the brake device according to the present invention shown in FIG. 34. FIG. 34 shows the holding box 2 in the locked state. The state in which the movement of the vehicle is stopped is illustrated, and FIG. 35 illustrates a state in which the brake device is released to enable the movement of the holding box 2.

In the present invention, as illustrated in the drawings, the brake device, the brake pad 570 is mounted on the upper end and the lower end of the rotary bar (Rotary Bar) is rotatably coupled to the cable coupling portion 510 or the holding box (2) 571). When the rotation bar 571 rotates upward and the brake pad 570 comes into contact with the ropeway cable 1, the brake box 570 is in a "brake operating state" to prevent the holding box 2 from moving due to friction, and vice versa. When the brake pad 570 is no longer in contact with the ropeway cable 1 by rotating downward, the holding box 2 is moved to a "break release state". The rotary bars 571 are positioned at both sides of the cable coupling part 510, and the pair of rotary bars 571 positioned at both sides of the cable coupler 510 are connected to each other by the horizontal connecting bar 573. Both ends of the horizontal connecting bar 573 are rotatably coupled to a pair of rotating bars 571 respectively positioned in both transverse directions. And both ends of the horizontal connection bar 573 is coupled to move in the longitudinal direction of the rotation bar 571 along the rotation bar 571. Accordingly, when the horizontal connecting bar 573 is downward, the rotating bar 571 coupled to the horizontal bar 571 is rotated downward to release the brakes to move the holding box 2. On the contrary, when the horizontal connecting bar 573 is upward, the rotary bars 571 of both ends coupled thereto are rotated upward, and the brake is operated to make the holding box 2 impossible to move.

The elevating support bar 5730 is located at the center position of the horizontal connecting bar 573 for the vertical ascending and descending of the horizontal connecting bar 573, and two pulleys, that is, the upper and lower pulleys, are provided at the elevating support bar 5730. 576 and 577 are provided, and the horizontal connecting bar 573 is positioned between the upper and lower pulleys 576 and 577. The first brake tow line 578 is horizontally coupled from the one side and is turned downward through the upper pulley 576 and coupled upwardly through the lower pulley 577 and coupled with the horizontal connecting bar 573. have. In this configuration, when the first brake traction line 578 is pulled in the first direction (to the right in the drawing), the horizontal connecting bar 573 is lowered and the brake is released as described above.

The compression spring member 580 is vertically installed below the horizontal connecting bar 573 at a position spaced apart from both sides in the transverse direction with respect to the position where the elevating support bar 5730 is installed. As described above, when the first brake tow 578 is pulled in the first direction (to the right in the drawing) to release the brake, the horizontal connection bar 573 descends to release the brake and at the same time, the compression spring member 580 is compressed. Will be in a state. In this state, when the first brake pull line 578 is no longer pulled, the compression spring member 580 automatically inflates and restores the horizontal connecting bar 573 upward, thereby automatically restoring the brake to the operating state. do. Although the first direction holding box pull line for moving the holding box 2 in the first direction and the first brake pulling line 578 for operating the brake device may be provided separately, the compression spring member 580 as described above. In the case of having a configuration of automatically restoring to the brake operating state by using a reference numeral 1), the first brake tow line 578 can be used as the holding box tow line 28 for moving the holding box 2 in the first direction. That is, one string can be used together as the first brake tow line 578 and the holding box tow line. When the first brake traction line 578 is pulled in the first direction to move the holding box 2, the horizontal connection bar 573 descends as described above to release the brake. Since both ends of the horizontal connecting bar 573 only move along the rotation bar 571, the horizontal connecting bar 573 no longer lowers even when the first brake tow 578 is continuously pulled to move the holding box 2. The brake release state is maintained without going, and the holding box 2 is horizontally moved in the direction of pulling the first brake tow line 578, that is, in the first direction. When the movement of the holding box 2 is completed, the first brake tow line 578 is no longer pulled out. In the configuration in which the compression spring member 580 is provided, the compression spring member 580 is automatically inflated and restored to the horizontal connection bar. The brake is operated as the 573 is automatically lifted up, and the holding box 2 remains stationary on the ropeway.

If necessary, a second brake tow line 579 extending in a direction opposite to the first direction (second direction) in which the first brake tow line 578 extends may be further installed, and furthermore, the holding box 2 may be provided. Another holding box tow line for moving the vehicle in the second direction and the second brake tow line 579 for operating the brake device may be provided separately. The second brake tow line 579 proceeds horizontally from the opposite side to the first brake tow line 578, turns downward through the upper pulley 576, and then turns upward again through the lower pulley 577. To the horizontal connection bar 573. Accordingly, when the second brake pull cord 579 is pulled in the second direction (left to left in the drawing), the horizontal connecting bar 573 is lowered, and the brake is released as described above.

When the compression spring member 580 is provided, when releasing the pulled state of the second brake traction line 579, the horizontal connection bar 573 is automatically raised upward by the expansion and restoration of the compression spring member 580, and the brake is applied. Will work again. Accordingly, when the compression spring member 580 is provided as described above, like the first brake tow line 578, the second brake tow line 579 also serves as a holding box tow line necessary to move the holding box 2 in the second direction. It can also function. When the second brake pull cord 579 is pulled in the second direction, as described above, the horizontal connecting bar 573 descends to release the brake. Since both ends of the horizontal connecting bar 573 move only along the rotation bar 571, when the second brake tow line 579 is pulled continuously, the horizontal connecting bar 573 does not go down any more and the brake release state is maintained. The holding box 2 is horizontally moved in the second direction. When the movement of the holding box 2 is completed and the second brake tow line 579 is no longer pulled out, the compression spring member 580 is automatically inflated and restored, and the horizontal connecting bar 573 is automatically raised upward to brake the brake. The holding box 2 is kept stationary on the ropeway. As such, one string may be used together with the second brake tow line 579 and the second direction holding box tow line. When two brake tow lines 578 and 579 extending on both sides are provided and the two brake tow lines also function as holding box tow lines for lateral movement of the holding box, respectively, the first brake tow line 578 is pulled out and held. When the box 2 is moved in the first direction, the second brake tow 579 should naturally be released, and conversely, when the second brake tow 579 is pulled, the first brake tow 578 should be released.

As described above, in the outer wall working system of the aerial structure according to the present invention, while the outer wall working device 600 suspended in the holding box 2 is moved downward, while the outer wall work is in progress, and the outer wall working device 600 is pulled up again. During operation, the brake is operated so that the holding box 2 stops on the ropeway cable 1, and after the outer wall work of the corresponding working width is completed, the brake box of the holding box is released to horizontally move the holding box and then again. When the tension of the brake traction line is released, the brake is automatically operated again by the restoring force of the compression spring member 580, so that the holding box 2 is stopped and the outer wall work downward is repeated. The transverse movement along the ropeway cable is effective for continuous and very smooth exterior wall work.

FIG. 36 is a schematic perspective view showing an internal configuration of the holding box 2 provided in the ropeway system 100. The holding box 2 which is horizontally moved along the ropeway cable 1 is a member having an inner space, and a lifting device 551 for winding and releasing the vertical wire 3 is provided in the inner space. Various work lines such as electric wires, washing water hoses, high pressure air lines, etc. required for external wall work may enter the inner space of the holding box 2 and pass down through the through-hole 572, for which the holding box 2 In the inlet 570 for the introduction of the working ship is formed. The bottom plate of the holding box 2 is formed with a through hole 572 through which the vertical wire 3 penetrates downward. In order to prevent the wire 3 from excessively shaking when the wire 3 moves up and down through the through hole 572, a wire support 552 having a small hole through which the vertical wire passes is provided in the holding box ( It may be further provided in the internal space of 2).

The ropeway system as described above can be horizontally arranged very simply and firmly using the wall of the open window of the aerial structure, easily at any height of the aerial structure if the location of the wall of the open window is formed or the roof wall is located. Can be installed. Therefore, even if the outer wall work area is located at the middle of the height of the aerial structure or the lower floor, it is possible to hang the wires from the vicinity of the outer wall work area, rather than extending the wires from the rooftop, and thus the length of the outer wall work device 600 to hang is relatively. It is reduced to the outer wall work device 600 is exhibited the effect of reducing the distance to be raised and lowered. In particular, when the length of the outer wall working device 600 is reduced, the risk of shaking the outer wall working device 600 by the wind or the like decreases, thereby increasing work safety and greatly improving work efficiency. Ropeway systems can be applied to rooftop walls as well as walls of open windows in the same way.

In addition, even in a very high height structure such as a high-rise building, since the "ropeway system using an open window or a roof wall" can be easily applied as a horizontal movement means of the outer wall work device 600, even for any height height structure It is effective to perform various exterior wall works efficiently and economically. Furthermore, in the ropeway system 100, since the holding box is horizontally moved along the ropeway cable arranged horizontally, the outer wall work device 600 is easily horizontally moved to a desired position in the horizontal direction to perform the outer wall work. Being able to perform the effect that can significantly improve the progress and work efficiency of the exterior wall work.
