Technical Field
[0001] This utility model belongs to the field of wall spraying technology, specifically relating to a device for stabilizing the spraying distance of building exterior walls. Background Technology
[0002] Exterior wall coatings are used to paint the exterior walls of buildings. One of the most important indicators is resistance to ultraviolet radiation, requiring no discoloration even after prolonged exposure. They also need to be waterproof, self-cleaning, and easy to clean. Spraying requires centralized, one-time mixing of the coating to avoid color differences, and controlled spraying time to prevent damage to the substrate. However, the exterior walls of high-rise buildings have relatively large areas, with vertical working distances exceeding 100 meters. The coatings required for construction can weigh tons, posing inconvenience. Using "spider-men" for spraying is inconvenient, and using drones for spraying presents challenges in terms of weight, accuracy, safety, stability, and flight time. Therefore, a suspended platform is needed to spray the exterior walls of high-rise buildings. Maintaining a stable spraying distance during suspended platform operations is crucial for the spraying effect, especially given the frequent fluctuations in the relative distance between the platform and the wall due to airflow disturbances at high altitudes. How to maintain a stable spraying distance is a pressing issue that needs to be addressed. Utility Model Content
[0003] To overcome the aforementioned shortcomings, the inventors of this utility model, through long-term exploration, experimentation, and continuous innovation, have proposed a device for stabilizing the spraying distance of building exterior walls. This device utilizes a propeller to generate thrust, propelling the entire suspended platform towards the wall. The support arm and flexible rollers contact the wall, with the support arm length adjusted to the ideal spraying distance. The large-area flexible rollers prevent scratching the wall surface from previous processes. The rollers are made of flexible materials such as sponge, and the contact area is maximized to avoid damaging the wall. The flexible rollers and support arm are located below the spray nozzle, contacting surfaces that have already dried and hardened from the previous process, preventing them from crushing the freshly sprayed surface. A laser rangefinder precisely calibrates the thrust generated by the propeller, ensuring the flexible rollers remain in contact with the wall, preventing them from being blown away by high-altitude airflow, while also minimizing damage to the wall.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for stabilizing the spraying distance of building exterior walls is provided. It includes a wall support arm mounted on a suspended platform, a laser rangefinder, and a positive pressure generating device. The wall support arm is positioned between the suspended platform and the wall, and a roller is provided at the end of the support arm. The laser rangefinder is positioned on the side of the suspended platform closest to the wall to measure the distance between the suspended platform and the wall. The positive pressure generating device is positioned on the suspended platform to generate positive pressure on the side of the suspended platform away from the wall, causing the suspended platform to move closer to the wall. The laser rangefinder is electrically connected to the positive pressure generating device.
[0005] A further preferred technical solution of the building exterior wall spraying distance stabilization device according to the present invention is: positive air pressure generating equipment is set on both sides of the suspended basket.
[0006] A further preferred technical solution of the building exterior wall spraying distance stabilization device according to the present invention is: the positive pressure generating equipment is a positive pressure propeller, and a protective frame is set on the periphery of the positive pressure propeller.
[0007] A further preferred embodiment of the building exterior wall spraying distance stabilization device according to the present invention is as follows: the wall support arm includes a telescopic adjustment rod and an installation rod, the telescopic adjustment rod connects the basket and the installation rod, a roller is installed on the installation rod, and the telescopic adjustment rod is used to adjust the distance between the roller and the basket.
[0008] A further preferred embodiment of the building exterior wall spraying distance stabilization device according to the present invention is: the front end of the wall support arm is an installation rod parallel to the horizontal plane, and a roller is installed on the installation rod so that the rotation direction of the roller is perpendicular to the horizontal plane in the up-down direction.
[0009] A further preferred technical solution of the building exterior wall spraying distance stabilization device according to the present invention is: the roller is a drum-shaped structure or an ellipsoidal structure with a large middle and small ends, and the roller is made of flexible material.
[0010] A further preferred embodiment of the building exterior wall spraying distance stabilization device according to the present invention is that the roller is positioned in front of the suspended platform spraying device to avoid damaging the spraying surface.
[0011] A further preferred embodiment of the building exterior wall spraying distance stabilization device according to the present invention is that the positive wind pressure manufacturing equipment is symmetrically distributed on the suspended basket.
[0012] A further preferred technical solution of the building exterior wall spraying distance stabilization device according to the present invention is: the positive wind pressure manufacturing equipment is symmetrically distributed on both sides of the suspended basket.
[0013] A further preferred embodiment of the building exterior wall spraying distance stabilization device according to the present invention is that the laser rangefinder is mounted on the suspended basket and arranged in parallel with the wall support arm.
[0014] Compared with the prior art, the technical solution of this utility model has the following advantages / benefits: 1. The propeller generates thrust, propelling the entire suspended platform towards the wall. It contacts the wall via a support arm and flexible rollers. The support arm length is adjusted to the ideal spraying distance. Large-area flexible rollers prevent scratching of the previous layer of wall surface. These rollers are made of flexible materials like sponge, and the contact area is maximized to avoid damaging the wall. The flexible rollers and support arm are located below the spray nozzle, contacting surfaces that have already dried and hardened from the previous spraying process, ensuring they do not crush the freshly sprayed surface.
[0015] 2.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the detailed description of the embodiments of this utility model provided below is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model.
[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
[0023] Example 1: like Figure 1 As shown, a device for stabilizing the spraying distance of building exterior walls is disclosed. It includes a wall support arm 1011 mounted on a suspended platform 4, a laser rangefinder 2, and a positive pressure generating device 3. The wall support arm 1011 is positioned between the suspended platform and the wall, with a roller 102 at its end. The laser rangefinder 2, mounted on the suspended platform 4 near the wall 5, measures the distance between the platform and the wall 5. The positive pressure generating device 3, mounted on the platform 4, generates positive pressure towards the side of the platform away from the wall 5, bringing the platform closer to the wall 5. The laser rangefinder 2 is electrically connected to the positive pressure generating device 3. After detecting the distance, the laser rangefinder 2 can control the force of the positive pressure generating device 3 blowing air towards the rear of the platform, ensuring the platform is pressed firmly against the wall 5.
[0024] The positive air pressure generating equipment 3 is set on both sides of the suspended platform to avoid interfering with its operation. Of course, if necessary, it can also be set in other positions that do not interfere with the operation of the suspended platform, such as at the bottom. If it is set in other positions, it is necessary to consider not interfering with the overall stability of the equipment, and at the same time, the symmetrical structure should be maintained to ensure the stability of the suspended platform's movement. If necessary, the positive air pressure generating equipment 3 of the suspended platform should be operated in conjunction with the equipment.
[0025] The positive pressure generating device 3 is a positive pressure propeller, and a protective frame 302 is set around the positive pressure propeller. Of course, in practice, any device that can provide thrust and whose thrust is adjustable can be used. In actual use, the propeller is just a simple description of the principle, and it can be a fan or other similar blowing device.
[0026] The wall support arm 1011 includes a telescopic adjustment rod 1011 and a mounting rod 1012. The telescopic adjustment rod 1011 connects the suspended platform and the mounting rod 1012. A roller 102 is installed on the mounting rod 1012. The telescopic adjustment rod 1011 is used to adjust the distance between the roller 102 and the suspended platform. The telescopic adjustment rod 1011 is set with an initial distance according to the usage requirements. This distance can be used to control the distance between the suspended platform and the wall 5. For the telescopic adjustment rod 1011, it is only necessary to achieve stable fixation at the set distance. For example, it can be fixed by bolt compression and supplemented by secondary fixation with pins. The specific form of the telescopic adjustment rod 1011 is not limited. For example, it can adopt a square frame structure as shown in the figure, or a four-legged bracket structure, as long as it can achieve stable fixation.
[0027] The front end of the support arm 1011 of the wall 5 is a mounting rod 1012 parallel to the horizontal plane. A roller 102 is installed on the mounting rod 1012 so that the rotation direction of the roller 102 is perpendicular to the horizontal plane in the up and down direction. The main purpose of this structure is to keep the rotation direction of the roller 102 consistent with the movement direction of the suspended platform. The rest can be set up adaptively.
[0028] The roller 102 is a drum-shaped structure or an ellipsoidal structure that is larger in the middle and smaller at both ends. The roller 102 is made of flexible material and adopts a drum-shaped or ellipsoidal structure (actually, it is higher in the middle and lower at both ends, supplemented by a smooth transition surface). It can achieve deformation in the middle to provide strong support. After deformation, the lower ends can also contact the wall surface 5 to achieve a support function, achieving a support effect with a large contact surface. Therefore, the elastic value of the flexible material is related to the weight of the suspended basket, wind speed, etc., and can be selected as needed. When the roller 102 contacts the wall surface 5, the elastic material can also play a buffering role to avoid impact damage to the wall surface 5.
[0029] The roller 102 is positioned in front of the hanging basket spraying device to avoid damaging the spraying surface, that is, to ensure that the roller 102 will not roll over the new spraying area and to ensure that the paint layer of the already sprayed area is not damaged.
[0030] The positive pressure manufacturing equipment 3 is symmetrically distributed on the suspended basket. The symmetrical distribution can ensure the symmetrical stability when the distance is stable, and realize the synchronous pressing of both ends.
[0031] The positive air pressure generating equipment 3 is symmetrically distributed on both sides of the suspended platform. The arrangement on both sides can avoid interfering with the operation of the suspended platform.
[0032] The laser rangefinder 2 is mounted on the suspended platform and arranged parallel to the support arm 1011 of the wall 5. The laser rangefinder 2 is used to detect the distance between the suspended platform and the wall 5. After detecting the distance, it can be fed back to the positive wind pressure generating device 3. The wind pressure is controlled according to the distance. The farther the distance, the greater the required wind pressure and the farther the platform can move. The smaller the distance, the less required wind pressure and the less force is needed to avoid collisions. By placing the laser rangefinder next to the support arm 1011 of the wall 5, more accurate distance can be detected, and more accurate data monitoring can be achieved.
