Description

Technical Field

[0001] The present application relates to the field of building exterior wall spraying technology, and in particular to a building exterior wall spraying device. Background Art

[0002] In today's society, with the continuous development of the urbanization process, the number of high-rise buildings in cities is also increasing. The exterior walls of these buildings usually need to be spray-decorated, which not only affects the appearance of the buildings but also the overall appearance of the city.

[0003] Traditional exterior wall spraying mainly relies on hanging baskets or elevators to carry workers for spraying. However, manual spraying not only has disadvantages such as low efficiency and poor quality assurance of spraying, but most importantly, the personal safety of workers cannot be guaranteed.

[0004] Regarding the above related technologies, the inventor believes that there are problems such as the inability to guarantee the personal safety of workers in the process of traditional exterior wall spraying work. Summary of the Invention

[0005] In order to solve the problems of low work efficiency and low safety of manual painting, the present application provides a building exterior wall spraying device.

[0006] The building exterior wall spraying device provided by the present application adopts the following technical solutions:

[0007] A building exterior wall spraying device includes a guide rail device, a fixing device for fixing the guide rail device, a lifting device installed on the guide rail device, a moving device installed on the lifting device, and a nozzle installed on the moving end of the moving device. The nozzle is connected to an external paint source.

[0008] By adopting the above technical solutions, when the exterior wall of a building needs to be spray-decorated, the guide rail device is fixed by the fixing device so that the guide rail is vertically perpendicular to the outside of the building exterior wall, and at the same time, the guide rail device is placed at intervals from the exterior wall surface. The lifting device is started, and the lifting device drives the moving device to slowly descend at the upper part of the building. At the same time, the moving device is started to drive the nozzle on its moving end to move horizontally. With the up and down and horizontal movements of the lifting device and the moving device respectively, the nozzle can perform a comprehensive spraying operation on the exterior wall surface, thereby replacing manual spraying on the building exterior wall to improve the safety during the spraying work process. Spraying the exterior wall with a spraying device can not only significantly improve the efficiency of the spraying work, but also effectively improve the uniformity of the spraying compared with manual spraying based on work experience.

[0009] Optionally, the fixing device includes a first fixing component and a second fixing component respectively fixedly connected to both ends of the guide rail device;

[0010] The guide rail device includes two chain guide rails arranged at intervals, and a set of lifting devices are installed on each chain guide rail. The lifting device includes an installation box, a driving component installed inside the installation box, and an anti-retreat component;

[0011] The driving component includes a lifting sprocket group fixedly connected to the inner wall of the installation box, and a first motor connected to the lifting sprocket group and installed on the inner wall of the installation box.

[0012] By adopting the above technical solution, before use, one end of the chain guide rail is fixed to the roof of the building through the first fixing component, and the other end of the chain guide rail is fixed to the ground on the outer wall of the building through the second fixing component, so that the chain guide rail can be stably arranged outside the wall to be painted; start the first motor, so that the lifting sprocket group can move up and down on the chain guide rail, and the lifting sprocket group drives the installation box to move up and down. The lifting device has a simple structure and stable transmission, and a single chain guide rail is fixed stably, so that the lifting device will not generate large-amplitude shaking when moving up and down.

[0013] Optionally, a camera device is installed on the mobile end of the mobile device, and a wireless transmission module is provided on the camera device.

[0014] By adopting the above technical solution, the camera device can record the progress of the exterior wall painting work in real time. Through the wireless transmission module, the camera device can transmit the sprayed pictures to a display screen wirelessly connected to the camera device, so that the staff can observe the wall that has been painted in real time, reduce the work content of the later acceptance, and also reduce the possibility of rework due to uneven painting.

[0015] Optionally, the mobile device includes a detachable beam with two ends respectively connected to two installation boxes, and a horizontal sensor is installed on the detachable beam.

[0016] By adopting the above technical solution, when painting the exterior wall of a building, the horizontal sensor can monitor whether the detachable beam is in a horizontal state. When the horizontal sensor alarms, it is necessary to operate the leveling device to level the detachable beam. After leveling the detachable beam, it is convenient to spray different color paints on the same exterior wall surface later, and it is beneficial to keep the boundary between different paints horizontal.

[0017] Optionally, the detachable beam includes two connecting beams respectively fixedly connected to two installation boxes, a secondary cross beam with an end detachably connected to the end of the connecting beam, and a main cross beam with an end detachably connected to the end of the secondary cross beam. There are two secondary cross beams;

[0018] The moving device also includes a moving seat of the sliding device on the detachable beam, fixed pulleys respectively mounted on the two connecting beams, and a wire rope connected to the moving seat and located on the two fixed pulleys, and the nozzle is located on the moving seat;

[0019] An adjusting device is arranged on the side of the main beam away from the nozzle, and the adjusting device comprises an adjusting end, a second motor is mounted on the adjusting end, a driving wheel is mounted on the rotating shaft of the second motor, and the steel wire rope is located on the driving wheel.

[0020] By adopting the above technical solution, the length of the detachable beam can be increased or decreased according to the width of the paint spraying to achieve the purpose of improving the applicability of the spraying device. The adjusting device can support the steel wire rope at the same time. When the length of the detachable beam becomes smaller, the extra length of the steel wire rope can be stored and stored. Therefore, when the length of the detachable beam increases or decreases, there is no need to replace other steel wire ropes, and the spraying device can continue to work.

[0021] Optionally, a baffle device that can fit the exterior wall of the building is installed on the lifting device.

[0022] By adopting the above technical solution, when different colors of paint need to be sprayed on the exterior wall for decoration during the painting process, the practical baffle device can effectively shield the paint surfaces of different colors, thereby reducing the possibility of easy mixing of paints at the boundaries between different paints.

[0023] Optionally, the fixing device further comprises a supporting assembly, and a connecting assembly for connecting the supporting assembly;

[0024] The support assembly includes a first support block and a second support block, and a connecting groove penetrating the support blocks is provided on the side surfaces of the first support block and the second support block;

[0025] A sprocket support frame is fixedly connected to one end of the first support block, and a supporting sprocket is installed at one end of the sprocket support frame away from the first support block.

[0026] By adopting the above technical solution, the support assembly and the connecting assembly can store the unused chain guide rails and facilitate subsequent use; the sprocket support frame and the supporting sprocket can keep the chain guide rails and the wall surface of the building's exterior wall at a stable distance, which is convenient for subsequent painting work.

[0027] Optionally, the baffle device includes a second electric push rod with one end of the piston cylinder fixed to the connecting beam, a second connecting plate fixed to one end of the piston rod of the second electric push rod, an auxiliary baffle detachably connected to the second connecting plate, and a main baffle detachably connected to the auxiliary baffle;

[0028] There are two second electric push rods which are respectively located on two connecting beams, and there are two auxiliary baffles. Both ends of the main baffle can be detachably connected to the two auxiliary baffles;

[0029] The length of the baffle device is not less than the length of the detachable beam.

[0030] By adopting the above technical solution, the structure of the baffle device is simple, and the second electric push rod can be controlled to push the baffle to fit on the wall according to actual use requirements, so as to facilitate the formation of a clear boundary between different paints.

[0031] Optionally, reinforcing ribs are arranged on the surfaces of the main baffle and the auxiliary baffle facing the nozzle.

[0032] By adopting the above technical solution, the reinforcing ribs can effectively enhance the structural strength of the baffle, so as to reduce the thickness of the baffle itself and achieve the purpose of reducing the weight of the baffle.

[0033] Optionally, rubber pads are laid on the surfaces of the main baffle and the auxiliary baffle facing away from the nozzle.

[0034] By adopting the above technical solution, the rubber pads can make the baffle fit the outer wall surface better, reduce the possibility of gaps between the baffle and the wall surface, and thus reduce the possibility of paint flowing from between the baffle and the wall surface to another colored wall surface.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. By setting the guide rail device, fixing device, lifting device, moving device and nozzle, instead of manually spraying the building exterior wall, the safety during the spraying work process can be improved. Spraying the exterior wall with a spraying device can not only significantly improve the efficiency of the spraying work, but also effectively improve the uniformity of the spraying compared with manual spraying according to work experience;

[0037] 2. By setting the baffle device, when different color paints need to be sprayed on the exterior wall for decoration during the spraying process, the baffle device can effectively block different color paint surfaces, thereby reducing the possibility of paint mixing at the boundary between different paints;

[0038] 3. By setting the camera device, the progress of the exterior wall spraying work can be recorded in real time, and the sprayed images can be transmitted to a display screen wirelessly connected to the camera device, so that the staff can observe the wall surface after spraying in real time and reduce the work content of the later acceptance.

After the second connecting plates 82 are installed, they are at a 90° angle to the axis of the second electric push rod 81, and the second connecting plates 82, the auxiliary baffles 84, and the main baffle 83 are coplanar after installation.

[0079] Combined with Figure 5 and Figure 6 , on the plate surface of each set of detachable baffles facing the detachable beam 42, a reinforcing rib 85 in a frame structure is installed. The reinforcing rib 85 increases the strength of the detachable baffle, maintains the flatness of the plate surface of the detachable baffle, and enables the detachable baffle to better fit the exterior wall of the building. On the plate surface of each set of detachable baffles facing away from the detachable beam 42, a rubber pad 87 is installed, and the rubber pad 87 enables the detachable baffle to better fit the wall surface of the building 9.

[0080] During use, the two sets of baffle devices 8 cooperate with the two sets of moving devices 4 to work on the lifting device 3. When different paints need to be sprayed up and down, the two nozzles 5 on the two sets of moving devices 4 can be connected to different external paint tanks, so that the spraying work of two colors can be carried out successively, effectively improving the work efficiency. At the same time, the two sets of baffle devices 8 can form a good isolation effect, effectively ensuring the flatness at the connection line of different paints.

[0081] Combined with Figure 8 and Figure 9, each camera device 6 is installed on the surface of the high side plate of each moving seat 43 facing away from the detachable beam 42, and the camera device 6 is located above the nozzle 5. The camera device 6 includes a camera 61 installed on the high side plate, a protective housing 62 installed on the high side plate, a protective cover 63 installed above the protective housing 62, and a support base 64 installed below the protective housing 62. The camera 61 is located inside the protective housing 62. The camera 61 is provided with a wireless connection module, and through the wireless connection module, the video signal can be transmitted to a display screen wirelessly connected to the camera 61.

[0082] Combined with Figure 8 and Figure 9 , the protective housing 62 is in the shape of a rectangular cylinder with barrel openings at both ends. The protective housing 62 is horizontally arranged and one end is installed on the high side plate. A sealing ring 621 is installed on the end face of the end of the protective housing 62 away from the high side plate. The sealing ring 621 is arranged along the end face of the protective housing 62 and is only arranged at the two side edges and the upper edge of the end face.

[0083] Combined with Figure 8 and Figure 9 , a glass plate (not shown in the figure) with the same size as the barrel opening is installed on the barrel opening at the end of the protective housing 62 away from the high side plate of the moving seat 43, which is convenient for protecting the camera 61 from being contaminated by paint, so that the camera 61 can always clearly capture the painting situation of the wall.

[0084] Combined with Figure 8 and Figure 9 , the protective cover 63 is an L-shaped structure composed of a horizontal side plate and a vertical side plate. One end of the horizontal side plate is hinged on the high side plate, and the vertical side plate is connected to the end of the horizontal side plate away from the moving seat 43. Two first electric push rods 631 and a connecting rod 632 are installed on the protective cover 63. One end of the piston cylinder of each of the two first electric push rods 631 is hinged on the high side plate, and the two first electric push rods 631 are respectively located on both sides of the horizontal side plate. The other ends of the two first electric push rods 631 are respectively hinged to the two ends of the connecting rod 632, and the connecting rod 632 is horizontally installed at the end of the bottom of the horizontal side plate away from the moving seat 43.

[0085] Combined with Figure 8 and Figure 9, during use, the first electric push rod 631 is activated. The first electric push rod 631 extends, and the connecting rod 632 drives the protective cover 63 to rotate upward. The protective cover 63 opens the protective shell 62, allowing the camera 61 to perform the shooting operation. Thus, the staff can stay away from the wall and observe the exterior wall painting condition. After use, the first electric push rod 631 contracts, and the connecting rod 632 drives the protective cover 63 to rotate downward. The protective cover 63 closes and cooperates with the sealing ring 621 to seal the protective shell 62. The sealing ring 621 makes the seal between the protective cover 63 and the protective shell 62 more airtight. At the same time, when closing the protective cover 63, it can buffer the protective cover 63, effectively reducing the possibility of the imaging device 6 shaking when closing the protective cover 63.

[0086] Combined with Figure 8 and Figure 9 , the support base 64 includes a second fixed plate 641 horizontally arranged with one side fixed on the high side plate of the moving base 43, a fixed groove 642 horizontally installed on the upper surface of the second fixed plate 641 and located on the side away from the moving base 43, a slider 643 adapted to the fixed groove 642 and slidably installed in the fixed groove 642, a first rack 644 integrally formed with the slider 643 and horizontally arranged, a third motor 645 fixedly installed below the second fixed plate 641 with its rotating shaft vertically penetrating the second fixed plate 641, a second gear 646 horizontally installed on the rotating shaft of the third motor 645 and meshing with the first rack 644, a first brush 647 vertically installed at the middle position of the slider 643, a second brush 648 used in cooperation with the first brush 647, and magnets 649 respectively installed at both ends of the two brushes. Two travel switches 65 are installed at the end of the protective shell 62 away from the high side plate. Both travel switches 65 are electrically connected to the third motor 645. The two travel switches 65 are respectively located on the horizontal two sides of the protective shell 62 and inside the upper part of the sealing ring 621. The first brush 647 can respectively contact the two travel switches 65. The second fixed plate 641 is located below the protective shell 62.

[0087] Combined with Figure 8 and Figure 9, the length and width of the second fixing plate 641 are both greater than those of the protective case 62. The length of the fixing groove 642 is consistent with that of the second fixing plate 641, and the width of the fixing groove 642 is less than the width by which the second fixing plate 641 extends beyond the protective case 62. The cross-section of the fixing groove 642 is T-shaped. The first brush 647 is located outside the glass, and the second brush 648 is located inside the protective case 62. The bristles of the two brushes both come into contact with the glass plate. The magnets 649 at both ends of the two brushes attract each other, enabling the second brush 648 to be suspended inside the protective case 62. When stains or water vapor appear on the glass, the third motor 645 is activated to drive the second gear 646 and the first rack 644, causing the slider 643 to drive the first brush 647 and the second brush 648 to move together to wipe the glass. When the first brush 647 contacts the two travel switches 65 respectively, the two travel switches 65 can respectively change the direction of the current flowing into the third motor 645, so that the first brush 647 and the second brush 648 move reciprocally in the horizontal direction, facilitating the camera 61 to better capture the exterior wall painting situation.

[0088] Combined with Figure 10 and Figure 11 , the adjusting device 7 includes a square tube 71 horizontally arranged and fixedly connected at one end in the groove on the side of the main crossbeam 422 away from the nozzle 5, a second rack 72 movably inserted into the square tube 71, a connecting member 73 vertically installed at the top of the square tube 71 and away from one end of the main crossbeam 422, two support rods 74 obliquely installed on both sides of the square tube 71, and a horizontal sensor 75 installed on one of the support rods 74.

[0089] Combined with Figure 10 and Figure 11 , the square tube 71 is suspended outside the main crossbeam 422, and the square tube 71 is located above the upper part of the lower side plate of the moving seat 43. The second motor 46 is installed at the end of the second rack 72 away from the main crossbeam 422. Both ends of the support rod 74 are installed in the groove and on one side of the square tube 71 respectively. The installation position of the support rod 74 does not affect the movement of the lower side plate of the moving seat 43. The horizontal sensor 75 can detect whether the detachable beam 42 is in a horizontal state. When the detachable beam 42 is tilted, the horizontal sensor 75 can send out a signal to remind the staff to make adjustments.

[0090] Combined with Figure 10 and Figure 11, the connecting member 73 includes a housing 731 vertically installed at the top of the square tube 71 and near one end of the second motor 46, a pin body 732 vertically and movably penetrating through both ends of the housing 731, a pull ring 733 installed at the top end of the pin body 732, a third spring 734 sleeved on the pin body 732 and located inside the housing 731, and an abutting plate 735 fixedly connected to the pin body 732 and located below the third spring 734. The housing 731 has a structure with an opening at one end and a closed end at the other end. The opening end of the housing 731 is fixedly connected to the square tube 71, and an opening for the pin body 732 to pass through is provided on the closed end of the housing 731. The pin body 732 is a cuboid with a wedge-shaped surface at the lower end. The wedge-shaped surface slopes downward and faces the main cross beam 422. The teeth of the second rack 72 are adapted to the wedge-shaped surface of the pin body 732. A hole for the lower end of the pin body 732 to pass through is provided on the square tube 71, so that the pin body 732 passes through the hole and engages with the second rack 72. The spring is in a compressed state and its two ends respectively abut against the closed end of the housing 731 and the abutting plate 735.

[0091] Combined with Figure 10 and Figure 11 , when increasing the length of the detachable beam 42, pull the pull ring 733 upwards. The pin body 732 moves upwards, the abutting plate 735 compresses the third spring 734, and the second rack 72 moves towards the main cross beam 422, then the available length of the extension wire rope 48 can be increased. After adjustment, release the pull ring 733, the pin body 732 moves downwards, and under the action of the third spring 734 in the compressed state, the pin body 732 can always engage with the second rack 72 to ensure the tensioned state of the wire rope 48. When the length of the detachable beam 42 decreases, the second rack 72 can be pulled in the direction away from the detachable beam 42 to tighten the redundant wire rope 48, and the moving device 4 can work normally.

[0092] The implementation principle of an exterior wall spraying device in an embodiment of the present application is as follows: After the staff fixes the position of the entire device, connect an external paint tank, make the wire rope 48 taut through the adjusting device 7, start the first motor 323, and the driving component 32 starts to move up and down on the chain guide rail 11. As the driving component 32 drives the installation box 31 to move, after the moving device 4 and the baffle device 8 installed on the installation box 31 reach the appropriate positions, the nozzle 5 starts to work, and at the same time the imaging device 6 is turned on to detect the spraying situation. During the work, if the horizontal sensor 75 sends out a signal that the detachable beam 42 is tilted, the driving component 32 will move up and down to adjust the detachable beam 42 to be balanced. During the work process, the auxiliary cross beam 423 can be increased or decreased according to the specific situation. When different colors need to be sprayed, the two nozzles 5 can be connected to external paint tanks of different colors to improve work efficiency.

[0093] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
