Technical Field

[0001] The utility model relates to the technical field of painting devices, in particular to a steel structure painting device. Background Art

[0002] A steel structure is a structure composed of steel metal materials and is one of the main types of building structures. The structure is mainly composed of components such as steel beams, steel columns, and steel trusses made of sections and steel plates. Since steel structures are all made of metal materials, in order to prevent steel structures from rusting, anti-rust measures such as painting are often taken on steel structures to extend the service life of steel structures.

[0003] In the prior art, during the construction of a steel structure building, it is inevitable to damage the paint layer on the surface of the steel structure. Therefore, after the construction of the steel structure building is completed, there are often operators who will spray the built steel structure building again to achieve the purpose of extending the service life of the steel structure building. However, this painting method is usually carried out at high altitudes, and the operator needs to move continuously at high altitudes to achieve full spraying of the steel structure building. This painting method is both time-consuming and unsafe. Summary of the Utility Model

[0030] Next, the embodiments of the present invention will be described according to the overall structure of the present invention.

[0031] A paint application device for steel structures, as Figures 1-7 shown, includes a tank body 1. A base 8 is fixedly connected to the bottom of the tank body 1. An extrusion bin 2 is fixedly connected to one side of the top of the base 8. A hydraulic pipe 3 is fixedly connected to the top of the extrusion bin 2. One end of the hydraulic pipe 3 is slidably connected to a first extrusion rod 4. A pedal 7 is fixedly connected to the top of the first extrusion rod 4. A spring seat 5 is fixedly connected to one side of the top of the base 8. One end of the pedal 7 is rotatably connected to one end of the spring seat 5 through a rotating shaft 23. The pedal 7 and the spring seat 5 are elastically connected through a spring 6. A second extrusion rod 28 is slidably connected to the inside of one end of the hydraulic pipe 3. A piston 29 is fixedly connected to the bottom of the second extrusion rod 28. A paint delivery pipe 10 is fixedly connected to one end of the extrusion bin 2. A sleeve 13 is movably connected to the top of the paint delivery pipe 10. One end of the sleeve 13 is movably connected to a rotating shaft 12. One end of the rotating shaft 12 is movably connected to a handle 11. A lead screw 25 is fixedly connected to the inside of the rotating shaft 12. An extension rod 15 is threadedly connected to the outside of the lead screw 25. Two groups of first fixing rings 14 are fixedly connected to the bottom of the sleeve 13. A second fixing ring 16 is fixedly connected to the end of the extension rod 15. A spray head 17 is threadedly connected to the end of the paint delivery pipe 10;

[0032] When in use, the user can push the push rod 20. The push rod 20 will apply a force to the bottom plate 18 and drive the universal wheel 19 to move at the same time, so as to realize the movement of the overall device;

[0033] When the user pushes the overall paint application device to the vicinity of a steel structure building that needs to be sprayed with paint, the user first restricts the universal wheel 19 to prevent the universal wheel 19 from moving;

[0034] After that, the user holds the handle 11 and can pick up the sleeve 13 and the paint delivery pipe 10;

[0035] Then the user rotates the rotating shaft 12 counterclockwise, which will drive the lead screw 25 to rotate counterclockwise. At the same time, it will drive the extension rod 15 to move, causing the extension rod 15 to continuously extend. When the spray head 17 at the top of the extension rod 15 moves to a position where it can spray the steel structure building to be painted, stop rotating;

[0036] Next, the user first opens the cover 22 and pours the paint to be sprayed into the tank body 1 from the feed port 21. After the tank body 1 is filled with paint, cover the cover 22;

[0037] At this time, the paint in the tank body 1 will flow along the bottom discharge port through the second one-way valve 24 and reach the inside of the extrusion chamber 2;

[0038] Then the user needs to step on the pedal 7 with the foot. The pedal 7 will rotate around the rotating shaft 23 and squeeze the first extrusion rod 4. The first extrusion rod 4 will squeeze the hydraulic oil inside the hydraulic pipe 3;

[0039] The hydraulic oil moves along the hydraulic pipe 3 and will squeeze the second extrusion rod 28, causing the second extrusion rod 28 to move, thereby pushing the piston 29 to move, and thus squeezing the paint inside the extrusion chamber 2;

[0040] Due to the existence of the second one-way valve 24, the paint cannot flow back into the tank body 1 and can only flow along the discharge port of the extrusion chamber 2 through the first one-way valve 9 and into the paint delivery pipe 10;

[0041] At this time, the user lifts the foot. Under the elastic action of the spring 6, the pedal 7 will return to the initial position, thereby driving the first extrusion rod 4 to return to the initial position, and further causing the second extrusion rod 28 and the piston 29 to return to the initial position;

[0042] During the return process of the piston 29, the air pressure inside the extrusion chamber 2 will change, and it will suck the paint inside the tank body 1. Due to the existence of the first one-way valve, the paint flowing into the paint delivery pipe 10 cannot flow back into the extrusion chamber 2;

[0043] The user continuously steps on the pedal 7, and the above work will be continuously repeated, causing the paint to continuously flow along the paint delivery pipe 10 until it is sprayed out from the spray head 17, thus realizing the painting work of the steel structure building.

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 . A feed port 21 is provided at the top of the tank body 1, and an external thread of the feed port 21 is connected with a cover 22. By setting the above structure, the present utility model can convey the paint to be sprayed into the painting device.

[0045] Please refer to Figure 3 , two sets of sliding grooves 27 are provided inside the sleeve 13. Two sets of sliders 26 are fixedly connected to the outside of one end of the extension rod 15, and each set of sliders 26 is slidably connected to the sliding groove 27. By setting the above structure, the present utility model can make the extension rod 15 slide inside the sleeve 13, thereby driving the nozzle 17 to move.

[0046] Please refer to Figure 1 、 Figure 2 and Figure 3 , a plurality of bottom plates 18 are fixedly connected to the bottom of the base 8 through a plurality of bolts. One end of the top of the bottom plate 18 is fixedly connected to a push rod 20, and a plurality of universal wheels 19 are fixedly connected to the bottom of the bottom plate 18. By setting the above structure, the present utility model can move the overall painting device.

[0047] Please refer to Figure 3 、 Figure 4 and Figure 8 , a second one-way valve 24 is threadedly connected between the tank body 1 and the extrusion chamber 2, and a first one-way valve 9 is threadedly connected between the extrusion chamber 2 and the paint delivery pipe 10. By setting the above structure, the present utility model can control the flow direction of the paint.

[0048] Please refer to Figure 3 and Figure 6 , annular retaining rings are provided on the outer walls at both ends of the rotating shaft 12, and grooves are provided inside one end of the sleeve 13 and one end of the handle 11 to cooperate with the annular retaining rings at both ends of the rotating shaft 12. By setting the above structure, the present utility model can fix the sleeve 13 to the handle 11 and the rotating shaft 12, and can also make the rotating shaft 12 rotate independently.

[0049] Please refer to Figure 3 、 Figure 4 and Figure 8 , internal threads are provided inside both ends of the first one-way valve 9 and the second one-way valve 24. External threads are provided on the outside of the discharge port of the tank body 1 and the feed port of the extrusion chamber 2 to cooperate with the internal threads of the second one-way valve 24. External threads are provided on the outside of the discharge port of the extrusion chamber 2 and one end of the paint delivery pipe 10 to cooperate with the internal threads of the first one-way valve 9. By setting the above structure, the present utility model can tightly connect the tank body 1 to the extrusion chamber 2 and the second one-way valve 24, and can tightly connect the extrusion chamber 2 to the paint delivery pipe 10 and the first one-way valve 9.

[0050] The working principle of the present utility model is as follows: When in use, the user can push the push rod 20, and the push rod 20 will exert a force on the bottom plate 18, and at the same time drive the universal wheels 19 to move, thereby realizing the movement of the overall device;

[0051] When the user pushes the overall painting device to the vicinity of the steel structure building that needs to be painted, the user first restricts the universal wheels 19 to prevent the universal wheels 19 from moving;

[0052] After that, the user holds the handle 11 and can pick up the sleeve 13 and the paint delivery pipe 10;

[0053] Then the user rotates the rotating shaft 12 counterclockwise, which will drive the lead screw 25 to rotate counterclockwise. At the same time, it will drive the extension rod 15 to move, making the extension rod 15 continuously extend. When the spray head 17 at the top of the extension rod 15 moves to a position where it can spray the steel structure building that needs to be painted, stop rotating;

[0054] Next, the user first opens the cover 22 and pours the paint to be sprayed into the tank body 1 from the feed port 21. After the tank body 1 is filled with paint, cover the cover 22;

[0055] At this time, the paint in the tank body 1 will flow along the bottom discharge port through the second one-way valve 24 and reach the inside of the extrusion chamber 2;

[0056] Next, the user needs to step on the pedal 7 with the foot. The pedal 7 will rotate around the rotating shaft 23 and squeeze the first extrusion rod 4. The first extrusion rod 4 will squeeze the hydraulic oil inside the hydraulic pipe 3;

[0057] The hydraulic oil moves along the hydraulic pipe 3 and will squeeze the second extrusion rod 28, making the second extrusion rod 28 move, thereby pushing the piston 29 to move, and then squeezing the paint inside the extrusion chamber 2;

[0058] Due to the existence of the second one-way valve 24, the paint cannot flow back into the tank body 1 and can only flow along the discharge port of the extrusion chamber 2 through the first one-way valve 9 and enter the paint delivery pipe 10;

[0059] At this time, the user lifts the foot. Under the elastic action of the spring 6, the pedal 7 will return to the initial position, thereby driving the first extrusion rod 4 to return to the initial position, and further making the second extrusion rod 28 and the piston 29 return to the initial position;

[0060] During the return process of the piston 29, the air pressure inside the extrusion chamber 2 will change, and it will suck the paint inside the tank body 1. Due to the existence of the first one-way valve, the paint flowing into the paint delivery pipe 10 cannot flow back into the extrusion chamber 2;

[0061] The user continuously steps on the pedal 7, and the above work will be continuously repeated, making the paint flow continuously along the paint delivery pipe 10 until it sprays out from the spray head 17, thus realizing the painting work on the steel structure;

[0062] In summary, the user can move the painting device to the vicinity of the steel structure building to be painted. By continuously rotating the rotating shaft 12, the lead screw 25 inside the sleeve 13 can be continuously rotated, thereby achieving the effect of extending the extension rod 15, and further making the paint delivery pipe 10 movably connected to the extension rod 15 and the sleeve 13 continuously extend;

[0063] Finally, the spray head 17 at the end of the paint delivery pipe 10 can reach the vicinity of the steel structure building to be painted. By continuously stepping on the pedal 7, the paint in the tank body 1 continuously flows into the paint delivery pipe 10 through the extrusion bin 2 and is then sprayed out from the spray head 17;

[0064] Thus, the effect that the operator can paint the high steel structure building while standing on the ground is achieved, and further the technical problem that the operator needs to work at height to paint the steel structure building is solved, ensuring the safety of the operator.
