Description

Technical Field

[0001] This utility model belongs to the field of steel structure processing and surface treatment technology, specifically an adjustable steel structure spraying device. Background Technology

[0002] Steel structures are widely used in industrial buildings and infrastructure, and surface coating is a crucial step in corrosion prevention and extending service life. Currently, patent CN116140108B discloses a surface paint spraying device for steel structures, published on January 23, 2024. This device includes a support frame, clamps, a spraying mechanism, and a traveling mechanism. It can automatically move along the length of the workpiece and complete simultaneous spraying on both sides, thereby improving work efficiency. Simultaneously, the device also includes a cleaning component and a mixing component, which help improve the surface treatment quality before spraying. However, in practical applications, this device struggles to dynamically adjust the paint application amount according to changes in the workpiece's curvature during the spraying process, leading to uneven coating thickness on curved or irregular surfaces. Furthermore, its traveling mechanism relies on tracks, limiting the equipment's flexibility and applicability in complex construction sites.

[0003] Therefore, it is necessary to design an adjustable steel structure spraying device to solve the problems of coating uniformity and equipment flexibility mentioned above. Utility Model Content

[0029] Example 1:

[0030] like Figures 1 to 4 As shown, this embodiment provides an adjustable steel structure spraying device, comprising: a base 1 for support; a left-right adjustment component 2, disposed above the base 1 for adjusting the horizontal position of the spraying, including a second connecting plate 209 and a left-right drive mechanism for driving the second connecting plate 209; a base plate 3 connected to the left-right adjustment component 2 and having a lifting component 4 on its top, the lifting component 4 for adjusting the vertical position of the spraying, the lifting component 4 including a second nut 403 and a lifting drive mechanism for driving the second nut 403 to move up and down; and a spraying mechanism 5 disposed on the base plate 3 and connected to the lifting component 4 for spraying.

[0031] In this embodiment, the left and right adjustment components and the lifting components constitute an adjustable steel structure spraying device according to this application, which realizes uniform spraying of objects.

[0032] It should be noted that the base 1 is I-shaped, and its stable plane provides support to bear the weight of the components above and the force generated during the spraying operation, ensuring the overall stability of the device and preventing shaking during the spraying process. The left and right adjustment component 2 and the lifting component 4 drive the spraying mechanism 5 to move in the horizontal and vertical directions respectively, realizing two-dimensional adjustment of the spraying position. The spraying position can be flexibly adjusted according to the steel structure size and spraying requirements.

[0033] Specifically, the left and right driving mechanism includes: a drive motor 201, placed above the first connecting plate 202, and the first connecting plate 202 is connected to the base 1 by welding; a first lead screw 203, connected to the drive motor 201 by a coupling 205, and the first lead screw 203 is threadedly connected to the first nut 204; a horizontal guide slider 207, fixedly connected to the first nut 204 by a second connecting plate 209; and disposed above the slide rail 206, achieving left and right movement through a ball connection.

[0034] In this embodiment, the drive motor 201 rotates, which drives the first lead screw 203 to rotate through the coupling 205. The first nut 204 moves left and right along the first lead screw 203 under the action of the thread, which drives the horizontal guide slider 207 to slide left and right on the slide rail 206, thereby realizing the left and right movement of the second connecting plate 209. The horizontal position of the spraying can be precisely adjusted, and the precise horizontal adjustment of the spraying position can be achieved with an adjustment accuracy of ±0.1mm.

[0035] Specifically, the left and right adjustment component 2 also includes a stop 208, which is disposed on the base 1 and located at one end of the first lead screw 203, for preventing the first nut 204 from disengaging from the first lead screw 203.

[0036] In a preferred embodiment, when the first lead screw nut 204 moves to the end of the lead screw, the stop block 208 prevents it from moving further, preventing it from disengaging from the first lead screw 203, ensuring the safe operation of the device, and avoiding damage to components.

[0037] Example 2:

[0038] Based on embodiment 1, a lifting component 4 is provided;

[0039] Specifically, the lifting assembly 4 also includes: a guide rail 401, placed above the base plate 3; a second lead screw 402, threadedly connected to a second nut 403, the rotational movement of the lead screw is converted into the vertical movement of the lead screw nut along the lead screw axis; a limit block 404, welded above the guide rail 401, the limit block 404 serves the functions of equipment safety and position limitation; and a T-shaped slider 405, welded and fixed to the second nut 403, slidably connected to the limit block 404.

[0040] It should be noted that the rotation of the second lead screw 402 drives the second lead screw nut 403 to move axially, and the T-shaped slider 405 slides on the guide rail 401 accordingly, realizing the vertical movement of the spraying mechanism 5 and achieving precise vertical adjustment of the spraying position, with an adjustment accuracy of ±0.1mm.

[0041] Specifically, the lifting drive mechanism includes: a stepper motor 406, the output end of the stepper motor 406 is connected to a reducer 407, and the output end of the reducer 407 is connected to a second lead screw 402 for driving the second lead screw 402 to rotate.

[0042] In a preferred embodiment, the stepper motor 406 outputs power, which is reduced and amplified by the reducer 407, and then drives the second lead screw 402 to rotate, providing a stable driving force for the lifting assembly 4 and achieving precise position control.

[0043] Example 3:

[0044] Based on Example 2, a spraying mechanism 5 is provided;

[0045] Specifically, the spraying mechanism 5 further includes a spraying head 501, which is fixed to the second nut 403 by welding. A hose 502 is connected to the lower part of the spraying head 501 and the hose 502 is wound around and connected to the coil shaft 505 for winding and unwinding the hose 502.

[0046] It should be noted that the spray head 501 moves up and down with the second lead screw nut 403, and the hose 502 is wound up and down on the reel shaft 505 to ensure smooth paint delivery, realize the position adjustment of the spray head 501, and ensure the continuity of the spraying operation.

[0047] Specifically, a torsion spring 504 is provided on the side of the coil shaft 505. One end of the torsion spring 504 is connected to the rotating shaft inside the coil shaft 505, and the other end of the torsion spring 504 is connected to the coil shaft 505. It is used to drive the hose 502 to wind around the coil shaft 505, and the hose 502 is connected to the bottom pipe of the paint storage tank 503.

[0048] In this embodiment, when the spray head 501 rises, the hose 502 is pulled out, and the torsion spring 504 is twisted and stores energy; when the spray head 501 descends, the torsion spring 504 releases energy, drives the reel shaft 505 to rotate, and winds and retracts the hose 502, automatically retracting and extending the hose 502 to prevent the hose 502 from becoming loose or tangled, ensuring smooth paint delivery.

[0049] In use, the operator starts the drive motor 201 according to the spraying requirements. Then, the drive motor 201 drives the first lead screw 203 to rotate through the coupling 205, causing the first nut 204 to drive the horizontal guide slider 207 to move along the first lead screw 203. The rotational motion of the lead screw is converted into the horizontal movement of the lead screw nut along the lead screw axis, thereby adjusting the horizontal position of the upper spraying mechanism 5. At the same time, when it is necessary to adjust the vertical position, the stepper motor 406 is started, driving the second lead screw 402 to rotate, which in turn drives the second nut 403 to move up and down, thereby adjusting the vertical position of the spraying mechanism 5. Then, the pump is started to draw the spraying liquid from the paint storage tank 503 and deliver it to the spray head 501 through the hose 502 to realize spraying. The torsion spring 504 can keep the hose 502 always wrapped around the intermediate shaft of the coil 505, preventing the hose 502 from accumulating and affecting the delivery of the spraying liquid and improving the service life of the hose 502.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
