Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery and equipment, in particular to a ceiling spraying machine for building decoration and renovation. Background Art

[0002] When decorating a pointed ceiling, it is usually necessary to spray the top of the building. Traditional spraying is mainly done manually, and there are usually two ways of working: one is to build a scaffolding, and workers climb to the top to manually spray the wall in turn. During the operation, the scaffolding cannot be moved, and it is necessary to spray in different areas. After spraying, it needs to be dismantled and rebuilt to adjust the position. The operation efficiency is low and the safety performance is poor. The second is to use special manned lifting equipment to lift workers and paint to the roof in turn. Workers carry out spraying operations in a lifting platform or hanging basket. The spraying speed is slow, the spraying quality is poor, the paint transportation cost is high, and it is time-consuming and labor-intensive, making it difficult to meet the requirements of high-efficiency and high-quality spraying.

[0003] A Chinese patent with authorization announcement number CN205036054U discloses a ceiling sprayer for building decoration and renovation, including a sprayer, a sprinkler, an upper arm, a lower arm and a spray gun bracket. A waist joint is movably fixed on the sprinkler, the waist joint is movably connected to the upper arm, the top of the upper arm is movably connected to the lower arm joint, the lower arm joint is movably connected to the wrist joint through the lower arm, and the end of the wrist joint is connected to the spray gun bracket. A first drive motor is installed in the waist joint, a second drive motor is installed in the lower arm joint, and a third drive motor is installed in the wrist joint. Paint tubes are provided in the upper arm and the lower arm to realize the adjustment of different heights and angles of the spray gun bracket. The transmission precision is high, the action is fast, it replaces manual operation, has high safety performance, increases the spraying area and spraying uniformity, and improves the spraying quality.

[0004] Although the above technical solution overcomes the technical problems of traditional spraying methods that are time-consuming and labor-intensive and difficult to meet the requirements of high-efficiency and high-quality spraying, in the actual working environment of ceiling spraying, other equipment is also installed on the surface of the ceiling, such as lamps, switches and sockets, fire protection systems, etc. If these components are not avoided, their surface paint will be covered, thereby increasing the workload of subsequent construction and decoration, and will also cause time-consuming and labor-intensive problems. Therefore, avoiding these components for spraying is the point that this application focuses on, and thus a building decoration and decoration ceiling sprayer is proposed in this application.
