Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a wall protection layer spraying device for tunnel construction. Background Art

[0002] A tunnel is an engineering structure buried in the ground and is a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, etc. The structure of a tunnel consists of two parts: the main building and ancillary equipment. The main building consists of the tunnel body and the tunnel portal, and the ancillary equipment includes car shelters, fire-fighting facilities, emergency communications, and drainage facilities.

[0003] During tunnel construction, waterproofing equipment is required to lay waterproofing materials on the inner wall of the tunnel. However, some equipment is not equipped with wheels, making it impossible to move the equipment, increasing the labor cost, and not being suitable for tunnels of various apertures, which reduces the practicality of the equipment. In addition, some equipment sprays unevenly and is not suitable for curved tunnels, which greatly reduces the utilization rate of the equipment.

[0004] At present, the Chinese utility model with the publication number CN216879913U discloses a tunnel construction waterproof material spraying device, including a connecting column and a frame bottom plate. A motor is provided on one side of the center of the frame bottom plate and is fixedly connected. The motor is respectively provided with an open button, an off button, a forward button, and a reverse button. The outer side of the motor center is rotated and connected to the motor gear shaft. The side of the motor gear shaft away from the motor is fixedly connected to the motor gear. The motor gear and the frame gear are engaged with each other. The advantage of the tunnel construction waterproof material spraying device of the utility model over other utility models is that it can be used in tunnels with large, medium and small apertures, and is equipped with wheels for easy movement, reducing the workload of workers. The equipment uses motor rotation to drive the equipment to complete a series of spraying processes. It is simple, easy to understand and easy to operate. The equipment uses a curved plate design nozzle, which makes the equipment have great advantages in curved tunnels.

[0005] In response to the above problems, the existing patent provides a solution. When the staff sprays the protective layer on the wall inside the tunnel, they are usually required to manually stir the paint of the protective layer before spraying the wall, which increases the workload of the staff. In addition, the paint is easily solidified if it remains stationary for a long time during the spraying process, so the staff is required to stir the protective layer paint again, which reduces the work efficiency of the staff and is not conducive to the use of the staff. At the same time, in the process of spraying the wall, the paint cannot be shielded, which will cause the paint to splash, and the splashed paint cannot be effectively collected, so it will fall on the ground. It is time-consuming and laborious for the staff to clean up the paint later, so it cannot meet the use needs of the staff.

[0006] Therefore, a wall protective layer spraying device for tunnel construction is proposed. Utility Model Content

[0030] In this embodiment: by setting a base plate 1, a spraying component 2 and a collecting component 3, when the staff sprays the protective layer on the wall inside the tunnel, by starting the spraying component 2, it can be achieved that the staff does not need to manually stir the paint of the protective layer before spraying the wall, thereby reducing the workload of the staff and avoiding the situation where the paint solidifies after being stationary for a long time during the spraying process. Therefore, the staff does not need to stir the protective layer paint again, thereby improving the work efficiency of the staff, which is beneficial to the use of the staff. When spraying the wall, the collecting component 3 can be used to effectively block the splashing paint, thereby avoiding the splashing of the paint during spraying. At the same time, the splashing paint can be effectively collected so that it will not fall to the ground, so that the staff does not need to clean the base plate 1 later, thereby meeting the use needs of the staff.

[0031] Specifically, such as Figure 1 、 Figure 3 As shown, the collection component 3 includes a collection cover 301, which is clamped on the outside of the high-pressure nozzle 207. The bottom of the collection cover 301 is connected to a return pipe 302. The rear side of the return pipe 302 is bolted to the absorption end of the recovery pump 303. The discharge end of the recovery pump 303 is bolted to a liquid guide tube 304. The rear side of the liquid guide tube 304 is connected to the recovery box 305.

[0032] Specifically, such as Figure 1 、 Figure 3 As shown, a ball 4 is provided on the front side of the collecting cover 301 , and the ball 4 is rotatably connected to the inner side of the collecting cover 301 , and there are several balls 4 .

[0033] Specifically, such as Figure 1 、 Figure 5 As shown, a supporting frame 5 is bolted to the top of the base plate 1 , and the high-pressure nozzle 207 is clamped on the inner side of the supporting frame 5 .

[0034] In this embodiment: by providing a collection cover 301, a return pipe 302, a recovery pump 303, a liquid guide pipe 304, a recovery box 305, a ball 4 and a supporting frame 5, when the staff is spraying the inner wall of the tunnel, the collection cover 301 can be used to block the paint splashed by the spraying, and then the recovery pump 303 is started to transport the splashed paint through the return pipe 302 and the liquid guide pipe 304 to the inside of the recovery box 305, so that the splashed paint can be effectively blocked, thereby avoiding the splashing of the paint during spraying. At the same time, the splashed paint can be effectively collected so that it will not fall to the ground, so that the staff does not need to clean the bottom plate 1 later, thereby meeting the staff's use needs. By providing the ball 4, it can be achieved that the collection cover 301 is facilitated to move on the wall, thereby facilitating the staff to spray the wall. By providing the supporting frame 5, the high-pressure nozzle 207 can be supported, thereby facilitating the staff to place the high-pressure nozzle 207 when not in use.

[0036] Specifically, such as Figure 1 、 Figure 5 As shown, a push-pull handle 7 is bolted to the rear side of the base plate 1 , and a protective cover is sleeved on the outer side of the push-pull handle 7 .

[0037] In this embodiment: by providing a scraping rod 6, it is possible to scrape the inner wall of the tank body 201 to prevent the protective layer paint from adhering to the inner wall of the tank body 201. By providing a push-pull handle 7, it is convenient for the staff to push and pull the spraying device, and at the same time protect the hands of the staff during the pushing and pulling process.

[0038] Specifically, such as Figure 1 、 Figure 5 As shown, universal wheels 8 are bolted to the bottom of the base plate 1 , and the universal wheels 8 are evenly distributed at the four corners of the bottom of the base plate 1 .

[0039] Specifically, such as Figure 4 As shown, a cylinder telescopic rod 9 is bolted to the bottom of the base plate 1 , and a limit plate 10 is bolted to the bottom of the cylinder telescopic rod 9 .

[0040] In this embodiment: by providing universal wheels 8, it is possible to facilitate the staff to move the spraying device, thereby facilitating the staff to spray different positions inside the tunnel. By providing a cylinder telescopic rod 9 and a limit plate 10, the spraying device can be limited in the process of the staff spraying the wall to prevent shaking during use.

[0041] Working principle: When the staff is spraying the protective layer on the wall inside the tunnel, the staff starts the driving motor 202 on the top of the tank body 201 to drive the stirring rod 203 to stir the internal protective layer paint. After the stirring is completed, the high-pressure pump 205 is started to transport the paint to the inside of the delivery hose 206 through the liquid extraction pipe 204, and then sprayed out through the high-pressure nozzle 207. It can be achieved that the staff does not need to manually stir the protective layer paint before spraying the wall, thereby reducing the workload of the staff and avoiding the situation where the paint will solidify if it is stationary for a long time during the spraying process. Therefore, there is no need for the staff to stir the protective layer paint again. The protective coating is stirred, thereby improving the work efficiency of the staff, which is convenient for the staff to use. Then, the collection cover 301 can be used to block the paint splashed by the spraying, and then the recovery pump 303 is started to transport the splashed paint through the return pipe 302 and the liquid guide pipe 304 to the inside of the recovery box 305. Therefore, the splashed paint can be effectively blocked, thereby avoiding the splashing of the paint during spraying. At the same time, the splashed paint can be effectively collected so that it will not fall to the ground, so that the staff does not need to clean the base plate 1 later, so it can meet the use needs of the staff.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
