Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment, and in particular relates to a uniform spraying device for anti-corrosion coating on steel structure surface. Background Technology

[0002] Steel structures are building structures formed by connecting steel materials through welding, bolting, or rivets. They are characterized by light weight, high strength, and fast construction, and are widely used in large factories, high-rise buildings, bridges, and other fields. Their core components include steel beams, steel columns, and steel trusses. Before being put into use, steel structures need to undergo anti-corrosion treatment. Commonly used anti-corrosion coatings include epoxy zinc-rich primer, epoxy micaceous iron oxide intermediate paint, and polyurethane topcoat. Anti-corrosion treatment can effectively block corrosive media such as oxygen, moisture, or salt, prevent steel from rusting and failing, effectively extend service life, and ensure the stability of the building.

[0003] In the process of steel structure anti-corrosion treatment, the surface spraying of anti-corrosion coating is a key step. Existing spraying equipment usually adopts a unidirectional spraying method, and the nozzle cannot move around the entire steel structure surface, resulting in spraying dead corners and reducing the anti-corrosion effect. Secondly, the paint droplets of existing spraying equipment are too large, which easily form particles on the paint surface, making the paint surface rough and uneven, affecting the protective performance. At the same time, the clamping mechanism of existing spraying equipment is usually designed with a fixed size, which cannot flexibly adjust the clamping range and is difficult to adapt to steel structures of different specifications and sizes. It is necessary to frequently change clamping parts of different specifications, which is cumbersome. Utility Model Content

[0004] The purpose of this utility model is to provide a uniform spraying device for anti-corrosion coating on steel structures, in order to solve the problems of existing spraying devices having dead corners and poor clamping adaptability.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a uniform spraying device for anti-corrosion coating on steel structure surface, including an operating table, a mounting plate slidably connected to the top of the operating table, a spraying mechanism, the spraying mechanism including a fixed ring connected to the top of the mounting plate, a toothed ring slidably connected to the inner wall of the fixed ring, multiple spray heads arranged around the fixed ring axis inside the toothed ring, the toothed ring being configured to rotate relative to the fixed ring and drive the spray heads to rotate, so that the spray heads rotate around the steel structure and spray the anti-corrosion coating on the outer surface of the steel structure, and a clamping mechanism, the clamping mechanism including a mounting ring connected to the top of the operating table, multiple rotating rods rotatably connected to one side of the mounting ring, a contact wheel rotatably connected to one end of each rotating rod, the multiple rotating rods being configured to be arranged along the axis of the mounting ring, and the steel structure being clamped and fixed by contacting the outer wall of the steel structure through the contact wheel.

[0006] Preferably, the inner wall of the toothed ring is provided with a plurality of mounting blocks along the axis, and the two nozzles are symmetrically arranged at corresponding positions on the outer walls of the mounting blocks on both sides.

[0007] Preferably, the top of the mounting plate is connected to two rotating frames, and a gear is rotatably connected between the two rotating frames. A first motor is installed on one outer wall of each rotating frame, and the output end of the first motor is connected to the outer wall of the gear.

[0008] Preferably, a sliding ring is slidably connected to the inner wall of the mounting ring, and a plurality of limiting blocks are rotatably connected to one side of the sliding ring. The rotating rod passes through the limiting block, and a limiting ring is rotatably connected to one side of the limiting block.

[0009] Preferably, a rotating plate is connected to the outer wall of the sliding ring, a connecting block is connected to one side of the outer wall of the mounting ring, a lead screw is rotatably connected to one side of the outer wall of the connecting block, a movable seat is provided outside the lead screw, and one side of the movable seat is rotatably connected to the rotating plate through a column.

[0010] Preferably, a second motor is installed on one side of the outer wall of the connecting block, and the output end of the second motor is connected to one end of the lead screw.

[0011] Preferably, the top outer wall of the operating table has two sliding grooves, and sliding plates are connected to both sides of the mounting plate. The outer wall of the sliding plate is slidably connected to the inner wall of the sliding groove.

[0012] Preferably, a push block is connected between the two slide plates, and an electric push rod is installed at the bottom of the operating table. The push rod of the electric push rod is connected to the corresponding position of the outer wall of one side of the push block.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, the spraying mechanism allows the spray nozzle to spray around the surface of the steel structure, preventing spraying dead angles. The nozzle axes of two adjacent nozzles intersect, allowing the sprayed paint to collide and atomize, dispersing large paint droplets into tiny paint droplets. This prevents paint droplets from forming particles on the paint surface due to their large size, ensuring a smooth and even paint surface. At the same time, the spraying mechanism can reciprocate, allowing for repeated spraying of the outer surface of the steel structure, thus improving the paint quality.

[0014] 2. In this utility model, the clamping mechanism can stably clamp and fix the steel structure, preventing the steel structure from shifting during the spraying process and causing uneven paint surface. At the same time, the clamping mechanism can adjust the clamping range through the second motor, which can clamp and fix steel structures of different specifications, thus improving the versatility of the device.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: a uniform spraying device for anti-corrosion coating on steel structure surface, including an operating table 1, an mounting plate 2 slidably connected to the top of the operating table 1, a spraying mechanism 7, the spraying mechanism 7 including a fixing ring 701 connected to the top of the mounting plate 2, a toothed ring 702 slidably connected to the inner wall of the fixing ring 701, a plurality of spray nozzles 704 arranged around the inside of the toothed ring 702 along the axis of the fixing ring 701, the toothed ring 702 is configured to rotate relative to the fixing ring 701 and drive the spray nozzles 704 to rotate, so that the spray nozzles 704 rotate around the steel structure and spray the anti-corrosion coating on the outer surface of the steel structure, and a clamping mechanism 8, the clamping mechanism 8 including a mounting ring 801 connected to the top of the operating table 1, a plurality of rotating rods 803 rotatably connected to one side of the mounting ring 801, a contact wheel 805 rotatably connected to one end of the rotating rods 803, the plurality of rotating rods 803 are all configured to be arranged along the axis of the mounting ring 801, and the steel structure is clamped and fixed by contacting the outer wall of the steel structure through the contact wheel 805.

[0019] Multiple mounting blocks 703 are arranged around the inner wall of the toothed ring 702 along the axis, and two nozzles 704 are symmetrically arranged at corresponding positions on the outer walls of the mounting blocks 703 on both sides.

[0020] The top of the mounting plate 2 is connected to two rotating brackets 705, and a gear 706 is rotatably connected between the two rotating brackets 705. A first motor 707 is installed on one side of the outer wall of the rotating bracket 705, and the output end of the first motor 707 is connected to the outer wall of one side of the gear 706.

[0021] Two sliding grooves 5 are provided on the top outer wall of the control panel 1, and sliding plates 3 are connected to both sides of the mounting plate 2. The outer wall of the sliding plate 3 is slidably connected to the inner wall of the sliding groove 5.

[0022] A push block 4 is connected between the two slide plates 3. An electric push rod 6 is installed at the bottom of the operating table 1. The push rod of the electric push rod 6 is connected to the corresponding position on the outer wall of one side of the push block 4.

[0023] Specifically, the first motor 707 drives the gear 706 to rotate via its output end. The teeth on the outside of the gear 706 mesh with the teeth on the outside of the gear ring 702, causing the gear 706 to rotate. Multiple mounting blocks 703 are arranged around the inner wall of the gear ring 702 along its axis. Spray nozzles 704 are symmetrically arranged on the outer walls of both sides of the mounting blocks 703, with the axes of the nozzles of two spray nozzles intersecting. After the anti-corrosion coating is sprayed from the nozzles of the spray nozzles 704, it collides at the intersection of the two nozzle axes. The impact force generated by the collision disperses large coating droplets into smaller droplets, preventing excessive coating droplet flow. Large particles are formed on the paint surface, making the painted surface smoother and flatter. The toothed ring 702 drives the mounting block 703 to rotate, and the spray head 704 follows the rotation of the mounting block 703, allowing the spray head 704 to rotate around the outer surface of the steel structure, preventing spraying dead corners. The electric push rod 6 drives the push block 4 to move back and forth through the push rod, which in turn drives the slide plate 3 to move. The slide plate 3 drives the mounting plate 2 to move back and forth along the slide groove 5. The mounting plate 2 drives the spraying mechanism 7 to move back and forth as a whole, allowing the spraying mechanism 7 to repeatedly spray the outer surface of the steel structure, ensuring the quality of the anti-corrosion coating.

[0024] It should be noted that the selection of the first motor 707 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0025] It should be noted that the electric push rod 6 mentioned above is a new type of linear actuator composed of a motor, a push rod, and a control device. It is an electric drive device that converts the rotational motion of the electric motor into the linear reciprocating motion of the push rod. This part is well-known technology in the field and will not be described in detail here.

[0026] A sliding ring 802 is slidably connected to the inner wall of the mounting ring 801. Multiple limiting blocks 804 are rotatably connected to one side of the sliding ring 802. The rotating rod 803 passes through the limiting block 804. A limiting ring 806 is rotatably connected to one side of the limiting block 804.

[0027] A rotating plate 810 is connected to the outer wall of the sliding ring 802. A connecting block 807 is connected to one side of the outer wall of the mounting ring 801. A lead screw 808 is rotatably connected to one side of the outer wall of the connecting block 807. A movable seat 809 is provided outside the lead screw 808. One side of the movable seat 809 is rotatably connected to the rotating plate 810 through a column.

[0028] A second motor 811 is installed on one side of the outer wall of the connecting block 807, and the output end of the second motor 811 is connected to one end of the lead screw 808.

[0029] Specifically, the steel structure is inserted through the opening of the mounting ring 801. The motor drives the lead screw 808 to rotate through its output end. The external thread of the lead screw 808 meshes with the internal thread of the moving seat 809, allowing the moving seat 809 to move along the direction of the lead screw 808. When the second motor 811 runs in the forward direction, the moving seat 809 moves closer to the connecting block 807 along the direction of the lead screw 808. One end of the rotating plate 810 rotates counterclockwise around the column on one side of the moving seat 809. The moving seat 809 drives the sliding ring 802 to rotate counterclockwise through the rotating plate 810. The limiting block 804 rotates clockwise relative to the sliding ring 802, causing the rotating rod 803 to rotate around the column on one side of the mounting ring 801, thereby bringing the three contact wheels 805 closer together and into contact with the steel structure. The tight fit of the walls clamps and fixes the steel structure. When the second motor 811 runs in reverse, the moving seat 809 moves away from the connecting block 807 along the direction of the lead screw 808. One end of the rotating plate 810 rotates clockwise around the column on one side of the moving seat 809. The moving seat 809 drives the sliding ring 802 to rotate clockwise through the rotating plate 810. The limiting block 804 rotates counterclockwise relative to the sliding ring 802, causing the rotating rod 803 to rotate around the column on one side of the mounting ring 801. This causes the three contact wheels 805 to move away from each other and release the clamping and fixing of the steel structure. There is damping between the contact wheel 805 and the inner wall of one end of the rotating rod 803. Multiple anti-slip grooves 5 are opened on the outer wall of the contact wheel 805 to increase the friction between the contact wheel 805 and the outer wall of the steel structure.

[0030] It should be noted that the selection of the second motor 811 and the control unit in the above description are selected as needed. This part is well-known technology in the field and will not be described in detail here.

[0031] It should be noted that, as described above, the lead screw 808 and the moving seat 809 constitute a lead screw structure. The lead screw is a precision transmission element that converts rotary motion into linear motion or vice versa. Its core function is to convert rotary motion into linear motion, achieving high-precision and high-efficiency linear transmission through the thread structure and rolling friction. This part is a well-known technology in the field and will not be elaborated here.

[0032] Working principle: In use, the operator places both ends of the steel structure into the clamping mechanism 8 through the opening of the mounting ring 801. Then, the operator starts the second motor 811 in the forward direction to clamp and fix the two ends of the steel structure. Then, the operator starts the first motor 707, and the spray nozzle 704 rotates around the outer surface of the steel structure to spray anti-corrosion coating. Then, the operator starts the electric push rod 6 to make the spraying mechanism 7 reciprocate to repeatedly spray the outer surface of the steel structure. After the spraying is completed, the operator turns off the first motor 707 and the electric push rod 6 and runs the second motor 811 in the reverse direction to take out the sprayed steel structure.
