  In the wall washer of the present invention, the anti-collision wheel provided in the anti-collision device 8 of the rack 1 employs an air ring, has a function of both surfaces, one is used for collision prevention, and a linear guide having an annular rail 4. By making the height higher than the rail 41, the linear guide rail 41 is protected so as not to collide with the wall surface, the other stabilizes the wall surface washing machine, functions to limit the displacement thereof, and has a function of adjustment. it can.

The wall cleaning machine of the present invention shown in FIG. 8 is relatively easy, simple and lightweight, and is particularly suitable for cleaning a high-rise wall.
FIGS. 9a and 9b show two configurations in which the present invention is used in conjunction with a hanging basket of a window cleaner.

  For safeguarding and carrying a person, it may be possible to adopt a method in which protective frames 11 are fixed to the upper and lower ends of the rack 1. As shown in FIG. 9a, a construction may be adopted in which the wall washer of the present invention is set outside the hanging basket 12 of the window cleaner, and at the same time the water storage container 9 is placed in the hanging basket 12 of the window cleaner. . The water storage container 9 may be placed in the hanging basket 12 of the window cleaner. As shown in FIG. 8b, the wall surface cleaner according to the present invention may be structured to be hung on the lower surface of the hanging basket 12 of the window cleaner.

When a person operates the wall cleaner, the nozzle lever 6 and the wall suction device 7 are not necessarily attached. If the situation permits, the water storage container 9 is not necessarily deployed.
It is possible to artificially clean such a wall surface by placing an operator in the hanging basket 12 of the window cleaner against a wall surface that is difficult to wash or a rugged wall surface. When processing the wall surface, it is possible to select whether to use the wall surface adsorption device 7 or to artificially operate the wall surface adsorption device 7 according to a specific implementation situation, and to fix the high-empty wall surface washer.

  As shown in FIG. 10, the wall washer of the present invention employs a structural form in which a water stop plate 14 is provided above the lower collision prevention wheel axle 13 in front of the rack 1. When the wall washer cleans the wall from bottom to top, the sewage that washed the wall often flows down and becomes secondary contamination. By providing the water stop plate 14 above the lower collision prevention wheel shaft 13, it is as close to the wall surface cleaning device 5 as possible and covers and protects the area under the wall cleaning device 5, thereby solving the problem of secondary contamination to the maximum. Since the water stop plate 14 may be designed in a J shape, one narrow tube used for connecting to the hose can be fixedly connected in the middle of the inner curve at the lower end, which is convenient for collecting sewage.

There are two types of structure of the water stop plate 14,
Proposal 1: As shown in FIG. 11 a, the arm 141 to which the water stopper plate 14 is attached is welded to the lower ends of the left and right upright columns at one end approaching the work surface of the wall washer, and the upper and lower surfaces of the other end of the arm 141 are welded. Two small horizontal plates are welded, a linear hole 142 is provided in the small horizontal plate, the small horizontal plate and the connection piece on the long horizontal plate 144 of the water stop plate 14 are connected by a screw, and the water stop plate 14 It is possible to install it by appropriately adjusting the distance of extension. Surface treatment of a system such as sticking an adhesive on the other side of the long horizontal plate 144 of the water stop plate 14 can be performed.

  Proposal 2: As shown in FIG. 11 b, the arm 141 to which the water stopper plate 14 is attached is welded to the lower ends of the left and right upright columns at one end close to the work surface of the wall washer, and one thin plate is attached to the end of the arm 141. 1 to 2 linear bearings 143 are fixed to one side of the thin plate, and a guide screw 145 and a guide screw 145 are placed on the long horizontal plate 144 of the corresponding water stop plate 14 at a position corresponding to the arm 141 and the linear bearing 143. A spring 146 is provided, and a surface treatment is performed on one side of the long horizontal plate 144 of the water stopper plate 14 in the same manner, such as attaching an adhesive to the surface. Because of the combination of the guide screw 145 and the linear bearing 143 and the action of the spring 146, when the water stop plate 14 comes into contact with the wall surface, the distance can be automatically adjusted.

  When the wall washer of the present invention is used for wall washing of a high-rise building, the rack 1 of the wall washer, the elevator and the crane are first connected together. When someone operates the wall cleaning machine, the wall surface cleaning device 5 is artificially placed to activate the wall cleaning device 5, and the PLC or single chip in the control system 3 performs water from the nozzle lever 6 based on the scheduled program. Alternatively, the cleaning agent is ejected, and the wall surface cleaning device 5 cleans the wall surface along the annular rail 4 according to a predetermined program. After the cleaning is completed, the cleaning program is restarted by artificially reducing the appropriate distance according to the working method of the hanging basket of the window cleaner.

  When no one operates, the wall cleaner of the present invention is set out of the window cleaner hanging basket 12 or under the window cleaner hanging basket 12 or lowered to the proper position by a direct crane hang. It becomes like this. As the linear reciprocating motor 71 of the wall surface adsorbing device 7 is activated and the linear moving rod 72 gradually approaches the wall surface, and at the same time, the linear moving rod 72 moves forward, the distance sensor 75 in the linear moving rod 72 is similarly moved to the wall surface. When approaching and reaching the set distance, the suction cup 74 is attached to the wall surface, and the distance sensor 75 sends a signal to the PLC or single chip of the control device 3 to stop the rotation (or reverse) of the linear reciprocating motor 71. The work of the vacuum pump system 73 is started, that is, the vacuum pump system 73 is turned on, the solenoid valve is turned off, the suction cup 74 is extracted into vacuum, the linear reciprocating motor 71 is reversed, and the starting point is restored. . The nozzle lever 6 ejects a cleaning agent or water, and the wall surface cleaning device 5 cleans the wall surface based on a scheduled program. In this process, the user can use one or two nozzle levers 6, one or a plurality of cleaning devices 5 depending on a specific situation. However, only one main drive slider 51 provided with a drive motor is used. After the cleaning of the wall surface is completed, the PLC or single chip issues a command based on the scheduled program, and the wall surface adsorption device 7 leaves the wall surface and lowers or raises the crane to the work surface of another location. In this process, since it can be remotely operated by a human hand and a signal can be sent by attaching a distance sensor or the like, a crane can be controlled and a fully automated operation can be realized.

As shown in FIG. 10, the wall washer of the present invention employs a structural form in which a water stop plate 14 is provided above the collision prevention wheel shaft 13 in front of the rack 1.
When the anti-collision wheel 8 attached to the front of the rack 1 replaces the anti-collision wheel shaft 13 and the anti-collision wheel shaft 13 contacts the wall surface, the water stop plate 14 on the front surface of the rack 1 also contacts the wall surface. Will be blocked without flying down. The structure of the collision prevention wheel shaft 13 employs a system in which a sponge is set outside the rubber tire.

  When water sprayed from the nozzle of the nozzle lever 6 to the wall flows downward along the wall, the drive motor 52 fixed to the main drive slide 51 provided with the first wiper plate 55 is activated, and the shaft of the drive motor 52 is activated. By driving the rotation of the end and the gear 53 that meshes with the toothed belt 45 on the annular guide 4, the main drive slide 51 is driven to travel forward along the guide 4. The driven slide 51 ′, which is successfully connected to the main drive slide 51 by the wire rope, drives the cleaning head 57 of the wall surface cleaning device 5, moves forward along the guide, moves to the linear guide 41, and then moves down. Begin wall cleaning from top to bottom. After the cleaning head 57 of the wall surface cleaning device 5 cleans the wall surface, it rotates from the driven slide 51 ′ to the 42 steps of the semicircular guide rail. After the cleaning head 57 leaves the wall surface, the first wiper plate 55 in the mounting holder 54 of the main drive slide 51 of the wall surface cleaning device 5 is driven by the gear 54 of the drive motor 52 so that the wall surface moves from top to bottom. The upper watermark and residue are scraped to achieve automatic cleaning of the wall here. After all wall cleaning, the outer wall cleaning machine is lowered to the lower cleaning position by the roof elevator, and the next automatic cleaning operation is continued. After cleaning up to the bottom layer, the wall washer is moved by the distance of the width of one cleaning head 57 in the lateral direction by the elevator on the roof, and then the wall is cleaned from the bottom to the top. What needs to be explained is that the drive motor 52 in the main drive slide 51 on which the first wiper plate 55 is provided rotates in the reverse direction when cleaning from bottom to top. In this way, the cleaning head 57 in the driven slide 51 'is driven by the main drive slide 51, and the wall surface is cleaned step by step from the bottom to the top. With the first wiper plate 55 in the mounting holder 54 of the main drive slide 51, the watermark on the wall surface is stepped down from the bottom up. If there is no dripping of water, the wiper operation need not be performed.

  It is not necessary to use the wall surface cleaning device 5 provided with the first wiper plate 55 for the non-smooth wall surface, and a device provided with the cleaning head 57 may be used. Depending on the contamination of the wall surface, the cleaning head 57 is conveniently replaced with a steel wire roller brush, or the cleaning process is performed with a roller brush to ensure the cleanliness of the wall surface cleaning.

  In the wall cleaning machine of the present invention, the main drive slide 51 of the wall cleaning apparatus 5 is provided with conductive wheels 58 that are in conductive contact with the respective conductive bands 46 on the inner surface of the annular rail 4. The slide 51 separately acquires the power output from the control device 3 with the conductive band 58 in contact with the slide 51 in its own rack without causing any interference.

  FIG. 13 shows that a plurality of sets of wall surface cleaning devices 5 are provided on the annular guide 4 of the wall surface cleaning machine of the present invention. The cleaning of the wall surface can be cleaned cleanly by the cleaning head 57 and the first wiper plate 55 of the plurality of sets of the wall surface cleaning device 5 in the process of circulating one week against the cleaning of the relatively dirty wall surface. Greatly increase efficiency.

  In the wall washer of the present invention, the clamp 15 is attached to the connecting rod 2 of the rack 1 without using a method of connecting and fixing the wire rope by drilling the normal connecting rod 2 in consideration of the balance and strength of lifting. It is attached. Specifically, the cavity of one rectangular (or circular) clamp 15 is divided into two symmetrical parts, side blocks 151 symmetrical to both sides of the clamp 15 are provided, and the side block 151 has a wire rope insertion hole 152. Then, a rubber 153 is provided in the cavity of the clamp 15, the clamp 15 is fixed at an appropriate equilibrium position on the connecting rod 2 via a screw screw nut 154, and the lifting and lowering is inserted through a wire rope and a hole through which the clamp 15 passes. What is necessary is just to latch a wire rope to each.

Of course, this proposal switches to a lifting structure and safety lock for the electric hanging basket.
The control process of the present invention is as follows. The PLC (or single chip) sends a command, the linear reciprocating motor rotates, and the linear moving rod gradually approaches the work surface together with the suction cup and sensor attached thereto, and simultaneously stores the time S1. When the sensor approaches a certain range on the work surface, the suction cup sticks to the work surface, sends a command, stops the forward movement of the linear reciprocating motor, turns on the vacuum pump, and the suction cup sucks the wall surface.

  The linear reciprocating motor reverses and similarly travels at time S1 and arrives at the initial position of the motor. After the four linear reciprocating motors have completed such an operation, the PLC (or single chip) dispatches commands and causes the wall washer to clean the work surface based on the scheduled program (also different Reduce sensor use by designing area setup times). After the cleaning operation is finished, the PLC (or the single chip sends out a command, the vacuum pump is stopped, the suction cup is released, and the wall washer can be raised or lowered.

  Moreover, the distance sensor used for the raising / lowering of a crane elevator may be attached in the appropriate position of this invention.

This embodiment is different from the first embodiment as follows.
In the present embodiment, only the two-stage linear guide 41 is used, and both ends of the two-stage linear guide 41 are connected to the fixed connecting rods 42 at the connection points of the fixed connecting rod 42 and the linear guide rail 41, respectively. A turning pulley 98 is provided.

  A guide lever 90 projects over the back of the driven slide 51 ′, and a spring 91 is provided on the guide lever 90. On the outside of the cleaning head 57, a wiper provided with two second wiper plates 92 that are respectively provided above and below the cleaning head 57 and connected to the elastic clip, and a wiper holder 93 from which the elastic clip projects. A mechanism is provided. The guide hole 90 is provided at a position corresponding to the guide lever 90 of the wiper holder 93, the guide lever 90 is slidably connected to the guide hole 94, and the spring 91 is interposed between the driven slide 51 ′ and the wiper holder 93. A suction nozzle 95 is provided on the back of the driven slide 51 ′ to slide the wiper holder 93 with respect to the driven slide 51 ′ by suction so that the second wiper plate 92 can be projected and wiped.

  Specifically, the cleaning head of the wall surface cleaning device and the second wiper plate are integrally provided, and the cleaning head has a cavity through which a rail is inserted and a pulley group is mounted therein. One side has a cleaning roller for mounting the outer rotor type motor system, and the four outer corners on the other side are screws without screws. The screw is connected to a spring, and a suction nozzle is attached and fixed to the middle portion. The screw and the suction nozzle correspond to the second wiper plate, and the second wiper plate and the four screws are attached and fixed. Corresponding to four linear bearings, the suction nozzle corresponds to a smooth plane.

  When washing from the bottom to the top, in order to prevent secondary contamination from occurring at the position where the sewage flowing down is washed, a water collecting plate 96 having a J shape is fixed to the lower end of the rack, and the hook portion 97 is It is provided on the inner side facing the rack and is used to collect wiped water. When collecting water, the hook portion 97 of the water collecting plate 96 can be connected to a water guide pipe connected to the water collector.

  In the present invention, an upper stroke sensor and a lower strok sensor can be provided at both ends of the linear guide rail. When washing from the bottom to the top, the main drive slide 51 is turned by the wire rope via the turning pulley 98, and then the washing head 57 in the driven slide 51 'is driven to wash the wall surface from the bottom to the top. When the driven slide 51 'arrives at the upper end of the linear guide rail, the upper stroke sensor is triggered to control the main drive slide 51 to stop after the signal is fed back to the PLC. Then move one cleaning distance. The PLC controls the main drive slide 51 to move downward to clean the wall surface. If there is water that falls, collect it with a water collecting plate. Moreover, the vertical movement is controlled by setting the movement time of the main drive slide 51 by PLC.

  According to the present invention, cleaning can be performed outdoors and the wall surface can be cleaned indoors. When cleaning an indoor wall surface, a caster 99 is provided at the bottom of the rack 1, and when the wall surface is being cleaned, the wall surface adsorbing device adsorbs and positions firmly after moving to the position where the cleaning is required via the caster 99. Then wash. When cleaning an indoor wall surface, the wall surface adsorption device does not have to employ an overhanging arm structure.

  The control process is as follows. The PLC (or single chip) sends a command, and the linear reciprocating motor rotates. The linear moving rod 72 gradually approaches the work surface together with the suction cup 74 and the distance sensor attached thereto, and simultaneously stores the time S1. When the distance sensor approaches a certain range on the work surface, the suction cup 74 sticks to the work surface, sends a command, stops the linear reciprocating motor 71 from moving forward, and the vacuum pump 73 is turned on. In this way, the suction cup 74 can be adsorbed to the wall surface.

  The linear reciprocating motor reverses and similarly travels at time S1 and arrives at the initial position of the motor. After all of the four linear reciprocating motors have completed such operations, the PLC (or single chip) sends a command to clean the work surface of the wall washer based on the scheduled program. . After the operation of the cleaning head 57 is finished, the PLC (or single chip) sends a command, and the vacuum pump system of the suction nozzle connected between the cleaning head 57 and the first wiper plate 55 is activated, and the suction is performed. The nozzle pulls the wiper holder 93 with respect to the driven slide 51 ′ so as to project the second wiper plate 92 to perform the wiper. After the wiper operation is finished, the suction cup and the suction cup are separated, and the wall washer can be raised or lowered.

  As shown in FIGS. 20, 21, 22, 23, and 24, the wall surface cleaning apparatus is divided into three parts: a slide 100, a cleaning roller 100A, and a wiper 100B. Two to four electromagnets (or motors and suction cups) 103 are fixed to the left and right ends of the slide 100. The electromagnets (motors) 103 are divided into two groups, each having two on the left and right sides. The shafts of the electromagnets (or motors) 103 are extended to be fixed to the upper surfaces of the cleaning roller 100A and the wiper 100B. I do. Therefore, by forming an open / close state between the cleaning roller 100A and the wiper 100B, it is possible to perform roller cleaning of the wall surface and free conversion of the wiper as necessary. Further, for the convenience of use and the reduction of push-pull resistance, a lifting shaft 101 whose middle is fixed to the slide 100 is provided. In the corresponding cleaning roller 100A and wiper 100B, linear bearings are attached, and the elevating shafts are respectively connected corresponding to the linear bearings, thereby reducing the push-pull resistance of the electromagnet.

Of course, the cleaning roller 100A and the slide 100 can be designed to be integrated as required. The use of the two electromagnets 103 can be reduced.
