Technical Field

[0001] The utility model relates to the technical field of wall maintenance, in particular to an automatic spray maintenance device for side walls of a subway station. Background Art

[0002] Wall spray maintenance is an indispensable part of construction, especially after the wall is plastered. Purpose and importance: Wall spray maintenance aims to keep the wall moist by evenly spraying water mist, thereby preventing cracks and shrinkage of the cement mortar layer due to rapid drying, and ensuring the flatness and strength of the wall. In addition, proper spray maintenance also helps the cement hydration reaction and improves the durability and safety of the wall. Operation process: Before spray maintenance, it is necessary to ensure that the water source is sufficient and the water quality meets the requirements, and remove debris and dirt on the wall. When spraying, it is necessary to use a suitable nozzle and adjust the water pressure to an appropriate spray intensity to ensure that the wall is sprayed evenly. During the spraying process, , be careful to avoid excessive or insufficient, and spray directly on the wall, maintenance cycle: the spray maintenance cycle is usually 5 to 7 days, the first 2 to 3 days, spray once a day; the 4th to 7th day, spray 2 to 3 times a day, so that the carefully maintained wall can not only ensure the strength, but also improve the appearance, matters needing attention: during the spray maintenance process, the status of the nozzle and pipeline must be checked regularly to ensure that there is no blockage or damage. At the same time, attention must be paid to the safety and environmental protection of the construction site to avoid adverse effects on the surrounding environment. In short, wall spray maintenance is an important part of construction and must be operated in strict accordance with the specifications to ensure the quality and safety of the wall.

[0003] The walls of subway stations need to be sprayed for maintenance. Most existing spray devices are manually sprayed, which is time-consuming and labor-intensive, increases the labor intensity of users, and has low efficiency, which is not conducive to user use. To this end, we propose an automatic spray maintenance device for the side walls of subway stations. Utility Model Content

[0026] The limiting mechanism 4 is arranged inside the spray box 2 and is used to limit the spray mechanism 3 .

[0027] The spray mechanism 3 includes a motor 301, which is fixedly mounted on the right side of the inner wall of the spray box 2. The output end of the motor 301 is fixedly connected to a first synchronous wheel 302, the surface of the first synchronous wheel 302 is meshed with a first synchronous belt 303, and the top of the first synchronous belt 303 is meshed with a second synchronous wheel 304. The rotation of the motor 301 drives the first synchronous wheel 302 to rotate, thereby driving the first synchronous belt 303 to rotate, and the second synchronous wheel 304 is driven to rotate through the first synchronous belt 303. Through the setting of the spray mechanism 3, it is convenient to quickly spray the wall surface 1, thereby improving the efficiency of the maintenance of the wall surface 1.

The rotation of the first bidirectional screw 305 drives the transmission synchronous wheel 306 to rotate, and drives the second bidirectional screw 308 to rotate through the second synchronous belt 307.

[0029] The first bidirectional screw 305 and the second bidirectional screw 308 are both movably connected with screw sleeves 309 on both sides of the surface, and the bottom of the screw sleeve 309 is movably connected with a clamping rod 310 through an axle pin, and the bottom of the clamping rod 310 is movably connected with a placement plate 311 through an axle pin.
