Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a portable spraying device for anti-corrosion treatment of steel structures. Background Technology

[0002] Steel structures are widely used in construction, bridges, and ships due to their high strength, lightweight, and design flexibility. However, corrosion caused by humid and polluted environments seriously affects their service life. Traditional manual brushing and air spraying methods have drawbacks such as low efficiency, unstable coating quality, and serious environmental pollution, prompting the industry to seek more efficient anti-corrosion solutions.

[0003] Existing portable steel structure anti-corrosion spraying devices typically rely on guide wheels and spraying equipment to work together when spraying the inside of steel pipes. However, since the diameters of the steel pipes to be sprayed vary, the equipment needs to be adjusted. Existing devices can only adjust the guide wheels or spraying components individually, and an operating interval must be reserved inside the steel pipe during the adjustment process. This makes the adjustment process cumbersome and complicated, thus affecting the spraying efficiency and equipment applicability. To address this, we propose a portable steel structure anti-corrosion spraying device. Utility Model Content

[0004] One of the technical problems to be solved in this application is: how to design a portable spraying device for anti-corrosion treatment of steel structures that can quickly and synchronously adjust the guide wheels and the spraying plate.

[0005] To address the aforementioned technical problems, this application provides a portable spraying device for anti-corrosion treatment of steel structures, comprising a protective shell, guide wheels, and a spraying mechanism. A spraying plate connected to the spraying mechanism is provided on the outer side of the protective shell. A threaded rod is provided on the inner wall of the protective shell, and a threaded ring is threaded on the outer surface of the threaded rod. A synchronous adjustment component is provided inside the protective shell, which can push the guide wheel and the spraying plate to adjust their deformation synchronously when the threaded ring moves.

[0006] In some embodiments, the synchronization adjustment assembly includes a connecting clamp sleeved on the outer surface of the guide wheel, a collar connected to the threaded ring being movably sleeved on the outer surface of the threaded rod, and two rotating plates being provided at the bottom of the connecting clamp. Each of the two rotating plates is provided with a fixing clamp connected to the connecting clamp. The fixing clamp at one end of one rotating plate is connected to the threaded rod, and the fixing clamp at one end of the other rotating plate is connected to the collar.

[0007] In some embodiments, the bottom of the connecting clamp is provided with an arched plate, the outer surface of the threaded rod is fitted with a guide ring, and a telescopic rod is provided between the guide ring and the arched plate.

[0008] In some embodiments, the end of the threaded rod is provided with a fixing rod that is connected to the inside of the protective shell, the outer surface of the fixing rod is fitted with a connecting ring, and the outer surface of the connecting ring is provided with an inclined plate.

[0009] In some embodiments, the end of the threaded ring is provided with a movable ring sleeved on the threaded rod, a connecting rod is provided between the side of the inclined plate and the end of the movable ring, and a U-shaped plate that movably fits the inclined plate is provided on the outer surface of the fixed rod.

[0010] In some embodiments, a spline groove is provided on the top of the U-shaped plate, a spline shaft is movably disposed inside the spline groove, an inclined rod is fixedly connected to the spray plate inside the spline shaft, the bottom end of the inclined rod is movably disposed on the inclined surface of the inclined plate, and a tension spring connected to the U-shaped plate is sleeved on the outer surface of the spline shaft.

[0011] In some embodiments, the side of the inclined plate is movably inlaid with ball bearings that are movably connected to the outside of the fixing rod.

[0012] This utility model has at least the following beneficial effects: by rotating and moving the threaded ring on the outer surface of the threaded rod, the synchronous adjustment component can be driven to realize the linkage adjustment of the length of the guide wheel and the spray plate. In this way, when spraying anti-corrosion materials on steel pipes of different diameters, there is no need to adjust them individually. The equipment parameters can be switched quickly, which significantly improves the adaptability and operational efficiency of the spraying operation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a portable spraying device for anti-corrosion treatment of steel structures, including a protective shell 11, a guide wheel 2 and a spraying mechanism 4. A spraying plate 3 connected to the spraying mechanism 4 is provided on the outer side of the protective shell 11. A threaded rod 6 is provided on the inner wall of the protective shell 11. A threaded ring 7 is threaded on the outer surface of the threaded rod 6. A synchronous adjustment component 5 is provided inside the protective shell 11, which can push the guide wheel 2 and the spraying plate 3 to adjust their deformation synchronously when the threaded ring 7 moves.

[0022] The spraying mechanism 4 and the spraying plate 3 are connected by a hose, and the spraying mechanism 4 can spray materials according to the set program. The guide wheel 2 can be made of rubber, which can increase the friction with the inner wall of the steel pipe.

[0023] The synchronous adjustment assembly 5 includes a connecting clamp 55 sleeved on the outer surface of the guide wheel 2, a collar 58 connected to the threaded ring 7 movably sleeved on the outer surface of the threaded rod 6, and two rotating plates 52 provided at the bottom of the connecting clamp 55. Each end of the two rotating plates 52 is provided with a fixing clamp 56 connected to the connecting clamp 55. The fixing clamp 56 at one end of one rotating plate 52 is connected to the threaded rod 6, and the fixing clamp 56 at one end of the other rotating plate 52 is connected to the collar 58.

[0024] The fixing clamp 56 connected to the threaded rod 6 along one of the rotating plates 52 will not move. The fixing clamp 56 at the end of the other rotating plate 52, being connected to the collar 58, will move under the drive of the threaded ring 7, thereby enabling the connection and guide wheel 2 to adjust its height.

[0025] An arched plate 57 is provided at the bottom of the connecting clamp 55, and a guide ring 54 is sleeved on the outer surface of the threaded rod 6. A telescopic rod 53 is provided between the guide ring 54 and the arched plate 57. Both the telescopic rod 53 and the guide ring 54 serve to guide and support. The arched plate 57 is provided to connect the telescopic rod 53 and the connecting clamp 55 and provide a movement trajectory.

[0026] The end of the threaded rod 6 is provided with a fixing rod 51 that is connected to the inside of the protective shell 11. A connecting ring 511 is sleeved on the outer surface of the fixing rod 51, and an inclined plate 510 is provided on the outer surface of the connecting ring 511.

[0027] The end of the threaded ring 7 is provided with a movable ring 514 sleeved on the threaded rod 6. A connecting rod 59 is provided between the side of the inclined plate 510 and the end of the movable ring 514. A U-shaped plate 513 that is movably fitted with the inclined plate 510 is provided on the outer surface of the fixed rod 51.

[0028] The movement of the threaded ring 7 on the threaded rod 6 can drive the moving ring 514 to move. When the moving ring 514 moves, it will drive the inclined plate 510 to move through the connecting rod 59.

[0029] The top of the U-shaped plate 513 is provided with a spline groove 515, and a spline shaft 512 is movably arranged inside the spline groove 515. A diagonal rod 517 fixedly connected to the spray plate 3 is arranged inside the spline shaft 512. The bottom end of the diagonal rod 517 is movably arranged on the inclined surface of the inclined plate 510. A tension spring 516 connected to the U-shaped plate 513 is sleeved on the outer surface of the spline shaft 512.

[0030] Moving the inclined plate 510 will drive the inclined rod 517 to move. The end of the inclined rod 517 is set with an inclined surface, and its inclined surface corresponds to the inclined surface of the inclined plate 510. The tension spring 516 can drive the inclined rod 517 and the spline shaft 512 to return to their original positions. The spline groove 515 opened on the U-shaped plate 513 corresponds to the spline shaft 512, so that the spray plate 3 can be raised and lowered to prevent it from rotating.

[0031] When using this device, if it is necessary to adjust the guide wheel 2 and the spray plate 3, firstly, the rotating threaded ring 7 moves on the outer surface of the threaded rod 6. The threaded rod 6 will drive the collar 58 to move. The collar 58 will drive the fixed clamp 56 and the rotating plate 52 to move. The other fixed clamp 56 and the rotating plate 52 have a fulcrum, so they will drive the connecting clamp 55 to move. At this time, the threaded ring 7 can also drive the moving ring 514 to slide on the outer surface of the fixed rod 51. The moving ring 514 will drive the connecting rod 59 at the end to move. The collar 58 will drive the inclined plate 510 to slide on the outer surface of the fixed rod 51. The inclined surface of the inclined plate 510 will press the inclined surface of the inclined rod 517, causing the inclined rod 517 to rise. When the inclined rod 517 descends, it will descend under the action of the tension spring 516, thereby completing the synchronous and rapid adjustment of the guide wheel 2 and the spray plate 3.

[0032] Example 2: Please refer to Figure 6 This utility model provides a technical solution: the side of the inclined plate 510 is movably inlaid with ball bearings 8 that are movably connected to the outer side of the fixed rod 51. When the inclined plate 510 is not moving, the ball bearings 8 reduce the friction on the outer surface of the fixed rod 51, thereby increasing the service life of the inclined plate 510.
