Description

Technical Field

[0001] This utility model relates to the field of building tools technology, specifically a wall cleaning device for pretreatment of exterior wall spraying. Background Technology

[0002] During exterior wall construction, a layer of paint is sprayed onto the exterior wall to improve its protective performance and reduce corrosion from rain and sunlight. However, when spraying the paint, the wall surface is often uneven due to the cement coating. If the cement is not applied evenly, the surface will be rough. When the paint is applied to these uneven areas, uneven spraying will occur, affecting the paint's protective properties. Therefore, pretreatment of the exterior wall surface is necessary before spraying.

[0003] When using a pretreatment device to process exterior walls, workers need to move the device onto the wall and control it to grind and level the surface. However, due to varying wall heights, scaffolding needs to be erected for pretreatment at higher locations to raise workers' height and allow them to treat the corresponding areas. Both erecting scaffolding and controlling the pretreatment device increase the workload of workers. Therefore, we propose a wall cleaning device for exterior wall spraying pretreatment. Utility Model Content

[0004] To address the shortcomings of existing wall cleaning devices for pretreatment of exterior wall spraying, this utility model provides a wall cleaning device for pretreatment of exterior wall spraying. It features the ability to adjust the position of the sliding rod outside the slide rail, and simultaneously activate the roller. The roller drives the connecting rope to rotate, allowing the height of the sealing sleeve to automatically move on the exterior wall surface. This reduces the workload of workers and improves work efficiency, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a wall cleaning device for pretreatment of exterior wall spraying, comprising a slide rail, a slide rod movably sleeved on the outside of the slide rail, a roller sleeved inside the slide rod via a bearing, a connecting rope sleeved on the outside of the roller, an installation plate fixedly connected to the end of the connecting rope, a sealing sleeve fixedly connected to the inside of the installation plate, a positioning sleeve fixedly connected to the side of the sealing sleeve, an auxiliary roller movably sleeved inside the positioning sleeve, a bellows fixedly connected to the front end of the sealing sleeve, a sealing gasket fixedly connected to the inside of the bellows, a spring installed inside the bellows, a clamp fixedly connected inside the sealing sleeve, and a motor installed inside the clamp.

[0006] Preferably, the two sets of slide rails are installed on the roof and the foundation respectively, and an electric motor is installed on the outside of the rollers.

[0007] Preferably, the connecting rope is movably sleeved between two sets of auxiliary rollers, and the connecting rope is installed on both sides of the sealing sleeve.

[0008] Preferably, the sealing sleeve is externally fixedly connected to a diagonal rod, the end of the diagonal rod is fixedly connected to a spring steel, the end of the spring steel is fixedly connected to a diagonal support foot, and the inner side of the diagonal support foot contacts the wall surface.

[0009] Preferably, the spring is installed between the sealing sleeve and the sealing gasket, and the bellows is wavy.

[0010] Preferably, the motor is located in the middle of the sealing sleeve, and a rotating disk is fixedly connected to one end of the motor output shaft. A grinding pad is fitted onto the outside of the rotating disk.

[0011] Preferably, a funnel is fixedly connected to the lower part of the sealing sleeve, a dust discharge pipe is fixedly connected to the lower part of the funnel, and an air pump and a dust collection box are installed at the end of the dust discharge pipe.

[0012] Compared with existing wall cleaning devices for pretreatment of exterior wall spraying, this utility model has the following advantages:

[0013] Beneficial effects:

[0014] 1. This wall cleaning device for pre-treatment of exterior wall spraying uses a sealing sleeve mounted on a connecting rope. By installing a slide rail on the exterior wall, adjusting the position of the slide rod outside the slide rail, and starting the roller, the roller drives the connecting rope to rotate. The connecting rope then adjusts the position of the sealing sleeve horizontally. As the sealing sleeve moves to different positions on the wall, the grinding pad installed inside the sealing sleeve grinds the wall surface, improving its neatness and facilitating subsequent spraying treatment.

[0015] 2. This wall cleaning device for pre-treatment of exterior wall spraying uses a grinding pad to grind the wall surface. The grinding generates dust, and the sealing gasket is attached to the wall surface under the action of the spring elasticity, which can collect the dust and prevent the dust from being discharged from the inside of the sealing sleeve. At the same time, the air pump installed on the outside of the dust exhaust pipe is activated, and the negative pressure generated by the air pump is used to absorb the dust, preventing the dust from being dispersed into the air and causing environmental pollution.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A wall cleaning device for pretreatment of exterior wall spraying includes a slide rail 1, a slide rod 2 movably sleeved on the outside of the slide rail 1, the slide rail 1 driving the slide rod 2 to adjust its position laterally, a roller 3 sleeved inside the slide rod 2 via a bearing, a connecting rope 4 sleeved on the outside of the roller 3, the roller 3 driving the connecting rope 4 to adjust its position, i.e., adjusting the height of a sealing sleeve 6, an installation plate 5 fixedly connected to the end of the connecting rope 4, a sealing sleeve 6 fixedly connected to the inner side of the installation plate 5, and a positioning sleeve 7 fixedly connected to the side of the sealing sleeve 6. An auxiliary roller 8 is connected to the internal movable sleeve of the 7. The auxiliary roller 8 limits the movement trajectory of the connecting rope 4 to ensure the stability of the connecting rope 4 during movement. A bellows 12 is fixedly connected to the front end of the sealing sleeve 6. A sealing gasket 13 is fixedly connected to the inner side of the bellows 12. A spring 14 is installed inside the bellows 12. The spring 14 pushes the sealing gasket 13 to move inward, so that the sealing gasket 13 continues to maintain a state of contact with the wall. A clamp 15 is fixedly connected inside the sealing sleeve 6. A motor 16 is installed inside the clamp 15.

[0024] Please see Figure 1Two sets of slide rails 1 are installed on the roof and the foundation respectively. At the same time, the roller 3 is equipped with an electric motor. After the slide rails 1 are installed on the roof and the foundation respectively, the cleaning device is set between the two sets of slide rails 1. The position of the slide rod 2 driven by the slide rail 1 is adjusted laterally. By starting the motor installed on the outside of the roller 3, the roller 3 can be driven to rotate. The roller 3 drives the connecting rope 4 to be wound up, that is, the height of the sealing sleeve 6 at the outer wall position can be adjusted. By adjusting the position of the slide rod 2, the convenience of spraying position adjustment is improved.

[0025] Please see Figure 1 The connecting rope 4 is movably sleeved between the two sets of auxiliary rollers 8. The connecting rope 4 is also installed on both sides of the sealing sleeve 6. By sleeved between the two sets of auxiliary rollers 8, the auxiliary rollers 8 limit the movement trajectory of the connecting rope 4 and improve the convenience of adjusting the position of the sealing sleeve 6.

[0026] Please see Figure 4 The sealing sleeve 6 is externally fixedly connected to a diagonal rod 9. A spring steel 10 is fixedly connected to the end of the diagonal rod 9. An inclined support foot 11 is fixedly connected to the end of the spring steel 10. The inner side of the inclined support foot 11 contacts the wall surface. The diagonal rod 9 is externally fixedly connected to the sealing sleeve 6. The inclined support foot 11 is installed on the side of the diagonal rod 9 through the spring steel 10. At the same time, the spring steel 10 drives the inclined support foot 11 to be installed on the wall surface. That is, the inclined support foot 11 keeps in contact with the wall surface, ensuring the stability of the sealing sleeve 6 when it is adjusted at different positions on the outer wall.

[0027] Please see Figure 5 The spring 14 is installed between the sealing sleeve 6 and the sealing gasket 13. Meanwhile, the bellows 12 is wavy. The bellows 12 drives the sealing gasket 13 to be installed at the front end of the sealing sleeve 6. Under the elastic action of the spring 14, the sealing gasket 13 is pushed to move towards the front end. At the same time, the sealing gasket 13 wraps around the outside of the cleaning area. The bellows 12 and the sealing gasket 13 can collect the dust generated when cleaning the wall, preventing the dust from spreading everywhere and affecting the surrounding environment.

[0028] Please see Figure 3 The motor 16 is located in the middle of the sealing sleeve 6. One end of the output shaft of the motor 16 is fixedly connected to the rotating disk 17. A sanding pad 18 is fitted to the outside of the rotating disk 17. When the motor 16 is started, the motor 16 drives the rotating disk 17 to rotate, and the rotating disk 17 drives the sanding pad 18 to rotate. During the rotation of the sanding pad 18, the sanding pad 18 sands the wall surface to avoid unevenness of the wall surface, which would affect the paint spraying effect.

[0029] Please see Figure 3A funnel 19 is fixedly connected to the lower part of the sealing sleeve 6, and a dust discharge pipe 20 is fixedly connected to the lower part of the funnel 19. An air pump and a dust collection box are installed at the end of the dust discharge pipe 20. The air pump and dust collection box are existing technologies and are not improved in this application, so they will not be described. With the funnel 19 installed at the lower end of the sealing sleeve 6 and the air pump and dust collection box installed on the outside of the dust discharge pipe 20, when the air pump is started, the air pump creates a negative pressure state inside the sealing sleeve 6. The negative pressure drives the dust to be collected into the interior of the dust discharge pipe 20, thereby improving the dust collection efficiency and reducing the problem of dust diffusion.

[0030] Working principle: In use, the slide rail 1 is installed on the roof and foundation, while the grinding pad 18 is installed against the wall. The inclined support foot 11 supports the position of the sealing sleeve 6 at an angle, improving the stability of the sealing sleeve 6 during position adjustment. At the same time, the slide rail 1 adjusts the position of the roller 3 laterally, and the roller 3 drives the position of the sealing sleeve 6 to adjust vertically, raising the position of the grinding pad 18 on the wall for adjustment. The motor 16 is started, and the motor 16 drives the grinding pad 18 to rotate. The grinding pad 18 polishes the wall surface to avoid unevenness, which would affect the spraying quality. After the grinding pad 18 pre-treats the wall surface, the dust generated by the treatment accumulates inside the sealing sleeve 6. By starting the air pump, the dust is extracted through the dust exhaust pipe 20, reducing the dust from being dispersed into the air and causing air pollution.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
