Description

Technical Field

[0001] This utility model relates to the field of steel structure spraying technology, and in particular to a steel structure outer surface spraying device. Background Technology

[0002] During the use of steel structures, spraying is usually required to improve their corrosion resistance and rust prevention. However, different steel structures have different shapes and sizes, and existing spraying equipment has certain functional limitations, making it difficult to meet the spraying requirements of different types of steel structures, resulting in unsatisfactory spraying effects and low work efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a steel structure outer surface spraying device to solve the problem that existing spraying equipment cannot handle the spraying of different types of steel structures.

[0004] This utility model is achieved through the following technical solution:

[0005] A steel structure exterior surface spraying device includes a base, a clamping mechanism, and a spraying mechanism. The clamping mechanism is set in a groove on the upper surface of the base. Two columns perpendicular to the base are set on both sides of the upper surface of the base. A horizontal plate is installed between the upper ends of the two columns. The spraying mechanism is installed below the horizontal plate. The spraying mechanism includes a lifting part, a rotating part, and a spraying part. The lifting part is vertically installed below the horizontal plate. The lower end of the lifting part is fixedly connected to the rotating part and the side is hinged to the spraying part through a connecting rod. The rotating part is connected to the spraying part through a horizontal telescopic rod.

[0006] Furthermore,

[0007] The lifting unit includes a threaded guide rod, a vertical guide block, and a limiting block. The threaded guide rod is fixedly inserted vertically downwards onto the horizontal plate. The vertical guide block is sleeved on the threaded guide rod. A limiting block parallel to the horizontal bar is set at the lower end of the vertical guide block. One end of the connecting rod is hinged to the perimeter of the vertical guide block, and the other end is hinged to the spraying unit.

[0008] Furthermore,

[0009] The rotating part includes a rotary motor and a rotary shaft. The rotary motor is mounted on the lower surface of the limiting block. The output end of the rotary motor is connected to the rotary shaft. Horizontal telescopic rods are connected around the rotary shaft.

[0010] Furthermore,

[0011] The spraying unit includes a shrink ring, a feed hopper, a storage bin, a micro pump, and a nozzle. The shrink ring is composed of four quarter-circle arcs. The four arcs are divided into two types: outer arcs and inner arcs. There are two of each type. The outer and inner arcs are alternately spliced ​​to form the shrink ring. The outer arcs can nest the inner arcs. The lower half of the inner side of the middle position of each arc is fixedly connected to a horizontal telescopic rod, and the upper half of the inner side is hinged to a connecting rod. A storage bin is set at the middle position of each arc, penetrating the shrink ring. The feed hopper is installed on the upper surface of the storage bin, and the micro pump is installed on the lower surface of the storage bin. The lower end of the micro pump is connected to the nozzle.

[0012] Furthermore,

[0013] The base has two identical grooves in a direction parallel to the horizontal plate. A lead screw is installed in each groove and passes through the left and right sides of the base to connect with the motor. A slider is installed on the lead screw in the groove, and the width of the slider is the same as the width of the groove.

[0014] Furthermore,

[0015] The clamping mechanism is installed on the upper surface of the slider. The clamping mechanism includes a support cylinder, a bearing plate, a support column, a clamping rotary motor, a U-shaped block, a support telescopic cylinder, and a pressure plate. The support cylinder is vertically arranged on the slider, and the other end of the support cylinder is vertically connected to the bearing plate. A support column is installed on the bearing plate, and a horizontal clamping rotary motor is installed on the inner side of the end of the support column. The other side of the clamping rotary motor is connected to the bottom of the U-shaped block. Support telescopic cylinders are vertically arranged on the inner side of the upper plate and the inner side of the lower plate of the U-shaped block, and pressure plates are installed on the output ends of the support telescopic cylinders.

[0016] Furthermore,

[0017] The inner side of the column has a vertical groove, and a threaded rod is installed in the groove. The bottom of the threaded rod is connected to the threaded rod rotation motor at the bottom of the groove, and a horizontal plate passes through the threaded rod.

[0018] Furthermore,

[0019] The horizontal telescopic rod reaches its maximum length precisely when the contraction ring is about to reach its maximum loop size.

[0020] The beneficial effects of this utility model are:

[0021] 1. The clamping mechanism can not only fix the steel structure, but also rotate the steel structure during the spraying process through the clamping rotary motor outside the U-shaped block. This is especially important for complex-shaped steel structures that require uniform spraying, ensuring the uniformity and comprehensiveness of the spraying.

[0022] 2. Driven by a rotating motor on a threaded rod, the horizontal plate and spraying mechanism can move up and down on the threaded rod, thereby adjusting the distance between the nozzle and the steel structure and changing the coverage area of ​​the nozzle. This design makes the spraying operation more flexible, allowing the density and uniformity of the spray to be adjusted as needed.

[0023] 3. By using a rotary motor to drive the rotating shaft and horizontal telescopic rod, along with the expansion and contraction mechanism of the shrink ring, the position of the nozzle in the horizontal direction can be further adjusted, increasing the flexibility and precision of the spraying operation. This design is particularly suitable for steel structures with complex shapes or large dimensions, ensuring that the spray coating covers all surfaces that need to be sprayed.

[0024] 4. The design of the storage silo and feed hopper makes paint management more convenient. When the paint is insufficient, it can be added immediately, avoiding the interruption of spraying operations due to insufficient paint. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] See the example. Figures 1 to 6 :

[0038] A steel structure exterior surface spraying device includes a base 1, a clamping mechanism 3, and a spraying mechanism 4. The clamping mechanism 3 is disposed in a groove opened on the upper surface of the base 1. Two columns 2 perpendicular to the base 1 are provided on both sides of the upper surface of the base 1. A horizontal plate is installed between the upper ends of the two columns 2. The spraying mechanism 4 is installed below the horizontal plate. The spraying mechanism 4 includes a lifting part 40, a rotating part 41, and a spraying part 42. The lifting part 40 is vertically installed below the horizontal plate. The lower end of the lifting part 40 is fixedly connected to the rotating part 41, and its side is hinged to the spraying part 42 through a connecting rod 5. The rotating part 41 is connected to the spraying part 42 through a horizontal telescopic rod 6.

[0039] The steel structure to be sprayed is clamped and fixed by the clamping mechanism 3. The rotating part 41 drives the spraying part 42 to rotate. The rotation of the spraying part 42 causes the lifting part 40 to move up and down. The lifting part 40 and the spraying part 42 are hinged and the length of the hinge is fixed. So when the lifting part 40 rises, the adjustable spraying part 42 can be contracted. When the lifting part 40 falls, the adjustable spraying part 42 expands.

[0040] Furthermore,

[0041] The lifting unit 40 includes a threaded guide rod 401, a vertical guide block 402, a connecting rod 5, and a limiting block 403. The threaded guide rod 401 is vertically fixedly inserted into the horizontal plate. The vertical guide block 402 is sleeved on the threaded guide rod 401. A limiting block 403 parallel to the horizontal bar is provided at the lower end of the vertical guide block 402. One end of the connecting rod 5 is hinged to the perimeter of the vertical guide block 402, and the other end is hinged to the spraying unit 42.

[0042] The vertical guide block 402 can move up and down on the threaded guide rod 401. The limiting block 403 is set to prevent the vertical guide block 402 from disengaging from the threaded guide rod 401 when it moves downward. The connecting rod 5 has a fixed length. When the spraying part 42 rotates, the connecting rod 5 will drive the vertical guide block 402 to rotate, thereby causing the vertical guide block 402 to move up or down, resulting in the angle between the connecting rod 5 and the vertical guide block 402 becoming smaller or larger, so that the spraying part 42 contracts or expands.

[0043] Furthermore, the rotating part 41 includes a rotating motor 410, a horizontal telescopic rod 6, and a rotating shaft 411. The rotating motor 410 is mounted on the lower surface of the limiting block 403, and the output end of the rotating motor 410 is connected to the rotating shaft 411. The horizontal telescopic rod 6 is connected around the rotating shaft 411.

[0044] The rotary motor 410 drives the rotary shaft 411 to rotate, causing the horizontal telescopic rod 6 mounted on the rotary shaft 411 to rotate, which in turn drives the spraying part 42 to rotate, causing the lifting part 40 to rise and fall, thereby causing the spraying part 42 to contract or expand. When the spraying part 42 contracts or expands, the horizontal telescopic rod 6 also contracts or expands accordingly.

[0045] Furthermore,

[0046] The spraying unit 42 includes a shrink ring 420, a feed hopper 421, a storage bin 422, a micro pump 423, and a nozzle 424. The shrink ring 420 is composed of four quarter-circle arcs. The four arcs are of two types: outer arcs 4200 and inner arcs 4201. There are two of each type of outer arc 4200 and inner arc 4201. The outer arcs 4200 and 4200 are alternately spliced ​​to form the shrink ring 420. The outer arcs 4200 can nest the inner arcs 4201. The lower half of the inner side of the middle position of each arc is fixedly connected to the horizontal telescopic rod 6, and the upper half of the inner side is hinged to the connecting rod 5. A storage bin 422 is set in the middle position of each arc, penetrating the shrink ring 420. The feed hopper 421 is installed on the upper surface of the storage bin 422, and the micro pump 423 is installed on the lower surface of the storage bin 422. The lower end of the micro pump 423 is connected to the nozzle 424.

[0047] The connection points of connecting rod 5 and horizontal telescopic rod 6 with the arc are all at the middle position of the arc. The purpose is to ensure that the force received by the contraction ring 420 is uniform when it contracts or expands, and that the contraction or expansion speed of each arc is the same.

[0048] Furthermore,

[0049] The base 1 has two identical grooves in a direction parallel to the horizontal plate. A lead screw 11 is installed in each groove and passes through the left and right sides of the base 1 and is connected to the lead screw motor 12. A slider 10 is installed on the lead screw 11 in the groove and the width of the slider 10 is the same as the width of the groove.

[0050] The purpose of having the same width of the groove as the slider 10 is to prevent the slider 10 from rotating with the lead screw 11 by using the groove wall, thereby allowing the slider 10 to move left and right within the groove.

[0051] Furthermore,

[0052] The clamping mechanism 3 is installed on the upper surface of the slider 10. The clamping mechanism 3 includes a support cylinder 30, a bearing plate 31, a support column 32, a clamping rotary motor 33, a U-shaped block 34, a support telescopic cylinder 341, and a pressure plate 342. The support cylinder 30 is vertically arranged on the slider 10. The other end of the support cylinder 30 is vertically connected to the bearing plate 31. The support column 32 is installed on the bearing plate 31. The horizontal clamping rotary motor 33 is installed on the inner side of the end of the support column 32. The other side of the clamping rotary motor 33 is connected to the bottom of the U-shaped block 34. The support telescopic cylinder 341 is vertically arranged on the inner side of the upper plate and the inner side of the lower plate of the U-shaped block 34. The pressure plate 342 is installed on the output end of the support telescopic cylinder 341.

[0053] The height is adjusted by using a support cylinder 30, and the clamping rotary motor 33 drives the U-shaped block 34 to rotate. The U-shaped block 34 is equipped with a support telescopic cylinder 341 and a pressure plate 342 at the output end of the support telescopic cylinder 341. The support telescopic cylinder 341 and the pressure plate 342 at the output end of the support telescopic cylinder 341 are used to fix the steel structure to be sprayed. The fixed steel structure will rotate together with the U-shaped block 34.

[0054] Furthermore,

[0055] The inner side of the column 2 has a vertical groove, and a threaded rod 20 is installed in the groove. The bottom of the threaded rod 20 is connected to the threaded rod rotation motor 21 at the bottom of the groove. A horizontal plate passes through the threaded rod 20. The horizontal plate can move up and down on the threaded rod 20 to adjust the distance between the spray nozzle 424 and the steel structure to be sprayed, and also adjust the coverage of the spray nozzle 424 on the steel structure.

[0056] Furthermore,

[0057] The horizontal telescopic rod 6 reaches its maximum length precisely when the contraction ring 420 is about to reach its maximum annular shape. The length of the horizontal telescopic rod 6 is used to limit the contraction ring 420, preventing the inner arc 4201 from disengaging from the outer arc 4200.

[0058] The principle of this utility model is as follows:

[0059] Before spraying, start the lead screw motor 12 to rotate the lead screw 11, allowing the slider 10 to move left and right on the lead screw 11. Adjust the distance of the clamping mechanism 3 according to the length of the steel structure. Then, start the support cylinder 30 to adjust the distance between the clamping mechanism 3 and the upper surface of the base 1 according to the height of the steel structure. After adjustment, place the steel structure on the clamping mechanism 3 and start the support telescopic cylinder 341 inside the U-shaped block 34 to push the pressure plate 342 to clamp and fix the steel structure. The clamping rotary motor 33 outside the U-shaped block 34 can rotate the U-shaped block 34 to make the steel structure... The system rotates together with the other components, and checks if there is any paint left in the storage silo 422. If there is no paint, paint can be added to the storage silo 422 through the feed hopper 421. Then, the micro pump 423 and the threaded rod rotary motor 21 are started simultaneously. The rotation of the threaded rod rotary motor 21 drives the threaded rod 20 to rotate, causing the horizontal plate 7 to move up and down on the threaded rod 20. This causes the spraying mechanism 4 on the lower surface of the horizontal plate 7 to move up and down as well, adjusting the distance between the spraying mechanism 4 and the steel structure below, thereby changing the coverage area of ​​the nozzle 424 below. When the horizontal plate 7 is at its highest point, the nozzle... Sprayer 424 has the maximum spray range downwards. If the spray range of nozzle 424 is still insufficient to completely cover the steel structure, the rotary motor 410 can be activated. The rotary motor 410 rotates the rotating shaft 411, causing the horizontal telescopic rod 6 and the contraction ring 420 connected to the horizontal telescopic rod 6 to rotate together. The connecting rod 5 is hinged to the contraction ring 420 and the vertical guide block 402, respectively. Therefore, when the contraction ring 420 rotates, it can drive the vertical guide block 402 to rotate, thus allowing the vertical guide block 402 to move up and down on the threaded guide rod 401. Since the length of the connecting rod 5 is fixed, when... When the vertical guide block 402 moves upward, the connecting rod 5 pulls the four quarter-circles that form the contraction ring 420 together to move towards the center, thereby causing the arcs to nest together and achieve the contraction of the contraction ring 420. When the guide block moves downward, the connecting rod 5 pushes the four quarter-circles that form the contraction ring 420 together to move away from the center, reducing the nested portion of the arcs and achieving the expansion of the contraction ring 420. The expansion and contraction of the contraction ring 420 changes the position of the nozzle 424 in the horizontal direction, and the rotation of the contraction ring 420 can change the spatial position of the nozzle 424.

[0060] Based on the above description, this utility model can accommodate steel structures of different shapes, sizes, and heights, and can be sprayed onto them.

[0061] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
