The device enables two second spraying pipes to be connected to the first spraying pipe through a fixing sleeve and an installation groove, thereby increasing the spraying area. The cooperation of the connecting spring, the pressing sheet, the limiting protrusion and the movable groove facilitates the disassembly and assembly of the second spraying pipe, and facilitates the change of the spraying area according to the terrain of the sprayed building. The threaded sealing cover can seal the two ends of the first spraying pipe, thereby improving the spraying efficiency of the spraying device and increasing the applicability of the spraying device to the spraying terrain. The base and the push handle can drive the storage box and the spraying unit to cooperate with the universal wheels to move freely, thereby reducing labor consumption and improving the spraying efficiency of the waterproof coating.

[0004] The above existing devices can increase the spraying area on the ground when in use. However, in the process of bridge construction, waterproof coating is usually sprayed on the ground and the side walls of the bridge. The above existing devices adjust the spraying angle according to the spraying position. At the same time, when the spraying vehicle of the above existing devices cannot move to a position, the above existing devices have certain limitations, which is inconvenient for the staff to carry the device for spraying work. Therefore, in view of the above problems, a waterproof coating spraying device for bridge construction is specially proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 6As shown, a waterproof coating spraying device for bridge construction comprises a movable spraying vehicle 1, a coating storage box 2 is arranged on the upper surface of the movable spraying vehicle 1, a booster pump 3 is arranged on the inner top wall of the coating storage box 2, a clamping spring telescopic rod 4 for clamping the top of the coating storage box 2 is evenly arranged on the upper surface of one end of the movable spraying vehicle 1, an angle adjustment bracket 5 is symmetrically arranged on the upper surface of the other end of the movable spraying vehicle 1, a coating main pipe 6 is rotatably installed on the angle adjustment bracket 5, a fixing component 7 for fixing the coating main pipe 6 is arranged on the inner wall of one side of the angle adjustment bracket 5, and a coating delivery pipe 8 is connected to the top of the coating storage box 2.

[0024] like Figure 2 As shown, a placement groove is provided on the upper surface of one end of the movable spraying vehicle 1, and one end of the paint storage box 2 is inserted into the placement groove, and an anti-slip pad 9 is laid on the bottom wall of the placement groove. The clamping spring telescopic rod 4 is respectively arranged at the four corners of the paint storage box 2, and an extrusion plate 10 is rotatably installed on the top of the clamping spring telescopic rod 4. One side surface of the extrusion plate 10 is tightly fitted with the upper surface of the paint storage box 2, and a linkage rod 11 is provided between the outer surfaces of the upper ends of the clamping spring telescopic rod 4 symmetrically arranged on one side of the paint storage box 2, so that when the staff places the paint storage box 2 in the placement groove, the staff can clamp and limit the top of the paint storage box 2 through the evenly arranged clamping spring telescopic rod 4 and the extrusion plate 10.

[0025] like Figure 4-Figure 6 As shown, a paint nozzle 12 is evenly connected to the outer wall of one side of the paint main pipe 6, and a pressure valve 13 is arranged in the paint nozzle 12. A joint threaded sleeve 14 is connected to the outer wall of the other side of the paint main pipe 6. A butt threaded sleeve 15 is sleeved on the outer surface of one end of the paint delivery pipe 8. The butt threaded sleeve 15 is rotatably engaged and arranged in the joint threaded sleeve 14. A spring groove is opened on the outer wall of one side of the upper end of the angle adjustment bracket 5. The fixing component 7 includes an adjustment spring 701, which is arranged in the spring groove, and one end of the adjustment spring 701 is provided with a conical The adjusting rod 702 and the side walls at both ends of the paint main pipe 6 are provided with a snap-in groove 16 along the circumference, and the conical adjusting rod 702 and the snap-in groove 16 are slidably snap-fitted with each other. An adjustable shoulder strap 17 is symmetrically provided on the outer wall of one side of the paint storage box 2, so that the staff can rotate the docking threaded sleeve 15 set at one end of the paint delivery pipe 8 into the joint threaded sleeve 14 set at one side of the paint main pipe 6. At the same time, the paint delivery pipe 8 is a hose with a certain length margin. When the staff needs to rotate the paint main pipe 6, the paint delivery pipe 8 can still carry out the paint delivery work.

[0026] When the utility model is in use, the staff moves the device to a suitable position, and then turns on the booster pump 3 in the paint storage box 2. The booster pump 3 can transport the paint in the paint storage box 2 to the paint delivery main pipe, and then transport it to the paint main pipe 6 through the paint delivery pipe 8. At this time, the paint main pipe 6 begins to accumulate paint under the action of the pressure valve 13 in the paint nozzle 12. When a certain pressure is reached, the paint will be sprayed out from one end of the paint nozzle 12, thereby completing the paint spraying work. At the same time, the staff can adjust the paint spraying position on one side of the paint main pipe 6 according to the spraying position. To adjust the angle of the paint nozzle 12, the staff can directly rotate the paint main pipe 6, and then engage the conical adjustment rod 702 with the engaging grooves 16 set at both ends of the paint main pipe 6 to complete the angle adjustment of the paint nozzle 12. When the staff finds that some spraying positions are movable spray vehicles 1 and cannot carry out paint spraying, the staff will disconnect the paint delivery pipe 8 from the paint main pipe 6. At this time, the staff will carry the paint storage box 2 on their back through the adjustable shoulder strap 17 to carry out spraying. The device has a simple structure and outstanding effect, and can enable the staff to efficiently complete the paint spraying work.
