Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to an external wall spraying device. Background Technique

[0002] With the continuous emergence of high-rise buildings, the amount of external wall spraying work has increased. Some significant technical defects have emerged in the existing external wall spraying devices during actual application, especially the problems of small horizontal coverage area and frequent need to move the hoisting position during the spraying operation of large-area high-rise external walls. These problems have greatly restricted the construction efficiency.

[0003] Most of the existing external wall spraying devices rely on external operation platforms such as traditional hanging baskets, hanging boards or aerial work platforms. To ensure balance, these platforms usually have limited spraying arm lengths designed, resulting in a relatively small horizontal coverage area of the spraying device. When spraying the large-area external walls of high-rise buildings, the position of the spraying device needs to be adjusted multiple times, which not only increases the construction time but also may lead to uneven spraying effects, affecting the overall aesthetics and protection performance of the external wall.

[0004] To solve these problems, improve the efficiency and quality of external wall spraying operations, and reduce construction costs, a new type of external wall spraying device with a larger horizontal coverage area and higher construction efficiency is urgently needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an external wall spraying device to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution:

[0007] An external wall spraying device includes a hanging basket, a spray head, an air compressor and a paint bucket. The hanging basket is driven to lift by a hoisting device installed on the roof of the building. The spray heads are arranged symmetrically on the front side of the hanging basket. The spray heads are connected to the air compressor and the paint bucket through pipelines. A spray head synchronous driving mechanism is arranged on the front side of the hanging basket. The spray head synchronous driving mechanism controls a pair of spray heads to move synchronously towards or away from each other. The spray head synchronous driving mechanism includes a pair of slide bars slidably installed and having the same width as the hanging basket. Rack teeth are provided on the opposite sides of the front and rear slide bars. A gear is installed at the central position on the front side of the hanging basket. The gear is meshed with the rack teeth and is driven to rotate by a driving motor installed at the bottom of the hanging basket.

[0008] Furthermore, a pair of sliding seats are fixedly installed on the front side of the hanging basket. The sliding seats are fixedly installed on the hanging basket through the mounting plates at the bottom. The slide bars are slidably installed on the sliding seats. The cross-sections of the slide bars and the inner chutes of the sliding seats are both arranged in a dovetail structure.

[0009] Further, one end of one side of the sliding bar is provided with a cantilever seat extending horizontally forward. A slider is slidably mounted on the cantilever seat, the spray head is fixedly mounted on the slider, and an electric telescopic rod is fixedly mounted at the rear side of the cantilever seat. The end of the telescopic column of the electric telescopic rod is fixedly connected to the slider.

[0010] Further, moving rollers are installed at the four corners of the bottom of the hanging basket. A pair of guide wheel mounting arms extending horizontally downward are fixedly mounted on the front side of the hanging basket, and a pair of vertically arranged guide wheels are mounted on each guide wheel mounting arm.

[0011] Further, a side railing extending upward is fixedly connected to each of the left and right sides of the hanging basket. A cross beam is connected between the left and right side railings, and a plurality of hanging hooks are equidistantly distributed on the cross beam.

[0012] Further, a panoramic camera is installed at the central position of the cross beam.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, since the spray heads are synchronously and symmetrically distributed on the front side of the hanging basket, no matter whether they move towards each other or away from each other, the overall mass distribution is relatively uniform, so that a large offset of the center of gravity of the hanging basket will not be caused. This design ensures the stability of the hanging basket during the spraying process and reduces potential safety hazards caused by unstable center of gravity. A pair of vertically arranged guide wheels are mounted on each guide wheel mounting arm, and during the working process, the guide wheels are closely attached to the wall to ensure the stability of the hanging basket. By arranging the spray heads in pairs and cooperating with the synchronous movement mechanism in the present utility model, the horizontal coverage area is increased, a larger spraying operation range can be completed at one time, and the time for repeated position adjustment is reduced.

[0015] 2. In the present utility model, the cross-sections of the sliding bar and the inner chute of the sliding seat are both arranged in a dovetail shape: on the one hand, one side of the sliding bar is exposed to facilitate the engagement of the rack and the gear; on the other hand, it has good load-bearing and anti-disengagement performance.

[0016] 3. In the present utility model, the electric telescopic rod drives the slider and the spray head to move back and forth, and the position of the spray head can be adjusted back and forth when encountering an uneven wall surface. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment 1: Please refer to Figures 1 to 7 , an external wall spraying device, including a hanging basket 1, a nozzle 15, an air compressor 18 and a paint bucket 17. The hanging basket 1 is driven to lift by a hoisting device installed on the roof. The nozzles 15 are arranged symmetrically on the front side of the hanging basket 1. The nozzles 15 are connected to the air compressor 18 and the paint bucket 17 through pipelines 16. A nozzle synchronous drive mechanism 5 is arranged on the front side of the hanging basket 1. The nozzle synchronous drive mechanism 5 controls a pair of nozzles 15 to move synchronously towards or away from each other; the nozzle synchronous drive mechanism 5 includes a pair of sliding bars 9 that are slidably installed and have the same width as the hanging basket 1. Rack 8 is provided on the side of the front and rear sliding bars 9 facing each other. A gear 7 is installed at the center position on the front side of the hanging basket 1. The gear 7 is meshed with the rack 8. The gear 7 is driven to rotate by a drive motor 6 installed at the bottom of the hanging basket 1.

[0027] Moving rollers 2 are installed at the four corners of the bottom of the hanging basket 1. A pair of horizontally extending downward guide wheel mounting arms 3 are fixedly installed on the front side of the hanging basket 1. A pair of vertically arranged guide wheels 4 are installed on each guide wheel mounting arm 3.

[0028] On both the left and right sides of the hanging basket 1, there is a side railing 20 fixedly connected and extending upward. Between the left and right side railings 20, there is a crossbeam 21, and a plurality of hanging hooks 22 are equidistantly distributed on the crossbeam 21.

[0029] A panoramic camera 19 is installed at the central position of the crossbeam 21.

[0030] The working principle of this embodiment:

[0031] The hanging hook 22 is connected to a rope, and the hanging basket 1 is lifted and lowered by a hoisting device installed on the roof to adapt to the external wall spraying requirements at different heights. The paint bucket 17 contains the paint to be sprayed, which is connected to the spray head 15 through a pipeline 16. The air compressor 18 provides stable air pressure for the spraying system, driving the paint to flow out of the paint bucket and be transported through the pipeline to the spray head. When the hanging basket 1 reaches the designated height, the driving motor 6 starts, driving the gear 7 installed at the central position on the front side of the hanging basket 1 to rotate. The gear 7 meshes with the racks 8 on the front and rear sliding bars 9, enabling the racks and the spray heads 15 installed on the racks to move linearly in opposite or away directions synchronously. This design allows the spray heads to be freely adjusted horizontally to cover a wider spraying area. As the spray heads 15 move synchronously, the paint is evenly sprayed onto the external wall under the action of the air pressure provided by the air compressor 18, achieving large-area and high-efficiency spraying operations.

[0032] Since the spray heads 15 are synchronously and symmetrically distributed on the front side of the hanging basket 1, regardless of whether they move towards or away from each other, their overall mass distribution is relatively uniform, so it will not cause a large offset of the center of gravity of the hanging basket. This design ensures the stability of the hanging basket during the spraying process and reduces potential safety hazards caused by unstable center of gravity.

[0033] A pair of upper and lower separated guide wheels 4 are installed on the guide wheel mounting arms 3. During the working process, the guide wheels 4 are closely attached to the wall to ensure the stability of the hanging basket.

[0034] The panoramic camera 19 facilitates video remote monitoring of the spraying process.

[0035] In this embodiment, by setting the spray heads 15 in pairs and cooperating with the synchronous movement mechanism, the horizontal coverage area is increased, a larger spraying operation range can be completed at one time, and the time for repeated position adjustment is reduced.

[0036] Embodiment 2: Please refer to Figures 4 to 6 , an external wall spraying device, which is different from Embodiment 1 in that a pair of sliding seats 11 are fixedly installed on the front side of the hanging basket 1. The sliding seats 11 are fixedly installed on the hanging basket 1 through the mounting plates 12 at the bottom. The sliding bars 9 are slidably installed on the sliding seats 11, and the cross-sections of the sliding bars 9 and the inner chutes of the sliding seats 11 are both set as dovetail-shaped structures.

[0037] In this embodiment, the cross-sections of the sliding bar 9 and the inner chute of the sliding seat 11 are both arranged in a dovetail structure: on the one hand, one side of the sliding bar 9 is exposed to facilitate the engagement of the rack and the gear; on the other hand, it has good load-bearing and anti-disengagement performance.

[0038] Embodiment 3: Please refer to Figure 7 , an exterior wall spraying device, which is different from Embodiment 1 in that a cantilever seat 10 horizontally extending forward is provided at the end of one side of the sliding bar 9, a slider 14 is slidably mounted on the cantilever seat 10, a nozzle 15 is fixedly mounted on the slider 14, an electric telescopic rod 13 is fixedly mounted at the rear side of the cantilever seat 10, and the end of the telescopic column of the electric telescopic rod 13 is fixedly connected to the slider 14.

[0039] In this embodiment, the electric telescopic rod 13 drives the slider 14 and the nozzle 15 to move back and forth, and the position of the nozzle 15 can be adjusted back and forth when encountering an uneven wall surface.
