A spraying device for processing steel structure columns in buildings

Abstract

This invention discloses a spraying device for processing steel structure columns in buildings, relating to the field of steel structure technology. The spraying device includes two bases, each with a support column fixedly connected to its top. A frame is fixedly connected between the two support columns, and a scraping mechanism is installed inside the frame. A paint storage cylinder is fixedly mounted on the front of one of the support columns, and a spray gun is fixedly connected to the front of the paint storage cylinder. The scraping mechanism includes a motor. Through the design of the scraping mechanism and the collection mechanism working together, the rotating plate vibrates by colliding with the outer surface of the collection shell, thereby accelerating the flow of paint inside the collection shell. This makes the paint inside the collection shell more concentrated, preventing it from drying quickly and avoiding the problem of thin layers of paint remaining on the inner wall of the collection shell drying out and becoming difficult to collect.

Description

Technical Field

[0001] This invention relates to the field of steel structure technology, specifically to a spraying device for processing steel structure columns in buildings. Background Technology

[0002] Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, making it particularly suitable for constructing large-span, super-high, and super-heavy buildings. It also has good homogeneity and isotropy, making it an ideal elastic body that best conforms to the basic assumptions of general engineering mechanics. Furthermore, it has good plasticity and toughness, allowing for large deformations and effectively withstanding dynamic loads. Construction time is short, and its high degree of industrialization enables highly mechanized and specialized production.

[0003] Currently, after spraying steel structures, air drying is required to ensure the quality of the coating. If a large number of steel structure columns need to be sprayed, a long waiting time is required, resulting in low work efficiency. Furthermore, uneven spraying is common during the process, causing the paint to flow continuously before it dries, leading to concentrated solidification and waste in some areas, requiring rework, which is very inconvenient. Therefore, further improvements are needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a spraying device for processing steel structure columns in buildings, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a spraying device for processing steel structure columns in buildings, comprising two bases, each base having a support column fixedly connected to its top, and a frame fixedly connected between the two support columns, the frame having a scraping mechanism inside, and a paint storage cylinder fixedly installed on the front of one of the support columns, the paint storage cylinder having a spray gun fixedly connected to its front.

[0006] The scraping and leveling mechanism includes:

[0007] The motor is fixedly connected to one of the support columns on the outside side. The motor is fixedly connected to a reciprocating lead screw through its output end. The reciprocating lead screw extends into the frame. A bearing seat is provided on the outside of the reciprocating lead screw. The bearing seat and the reciprocating lead screw are connected by a ball nut pair, so that the bearing seat can move laterally back and forth on the outer surface of the reciprocating lead screw.

[0008] A limit rod is fixedly connected to the rear side of the bearing housing, an mounting plate is fixedly installed on the top of the bearing housing, a fixing rod is fixedly connected to the top of the mounting plate, a positioning rod is fixedly connected to the top of the fixing rod, a collection shell is provided on the top of the positioning rod, and the positioning rod and the collection shell are movably connected through a damping rotating shaft, which allows the collection shell to rotate under manual assistance.

[0009] A heating plate is fixedly connected to one side of the collection shell, allowing the heating plate to be moved for drying.

[0010] Preferably, the reciprocating lead screw is connected to the frame and one of the support columns via bearings, and the positioning rod has a Z-shaped cross-section, allowing the reciprocating lead screw to rotate and be supported.

[0011] Preferably, a limiting groove is formed on the rear side wall of the inner cavity of the frame, and the limiting rod extends into the limiting groove, so that the limiting rod can limit the bearing seat.

[0012] Preferably, the outside of the collecting shell is provided with a collecting mechanism, which includes multiple guide rods. The multiple guide rods are all fixedly connected to the rear side wall of the inner cavity of the frame. The cross-section of the multiple guide rods is Z-shaped, which can facilitate the rotation of the rotating plate through the design of the guide rods.

[0013] Preferably, two clamping plates are fixedly connected to one side of the collecting shell. The two clamping plates are arranged in an opposing manner, and a rotating rod is rotatably connected between the two clamping plates to support the rotating rod.

[0014] Preferably, a rotating plate is fixedly connected to the outside of the rotating rod. The cross-section of the rotating plate is arc-shaped, and the arc-shaped design of the rotating plate allows it to brush over the outer surface of the guide rod.

[0015] Preferably, a plurality of restoring springs are fixedly connected to one side of the collecting shell, and one end of each of the plurality of restoring springs is fixedly connected to one side of the rotating plate, so that the restoring springs can be fixedly connected.

[0016] Preferably, the inner walls of the collection shell are provided with arc-shaped grooves, and counterweight scrapers are slidably connected inside the two arc-shaped grooves. The bottom end of the counterweight scraper contacts the inside of the collection shell, and the inside of the collection shell can be cleaned by the counterweight scraper.

[0017] This invention provides a spraying device for processing steel structure columns in buildings, which has the following beneficial effects:

[0018] 1. This spraying device for processing steel structure columns in buildings, through the design of the scraping mechanism, the fixed rod will drive the positioning rod and the collection shell to move simultaneously when it moves. During the movement of the collection shell, the paint concentrated on the outside and bottom of the steel structure column will be scraped off, thereby preventing paint waste and avoiding the need for manual cleaning of the work site.

[0019] 2. This spraying device for processing building steel structure columns, through the design of the scraping mechanism, continuously dries the coating on the already leveled building steel structure columns as the heating plate moves, avoiding the need for long waiting times for drying, saving workers' time costs, and improving the spraying efficiency of building steel structure columns.

[0020] 3. This spraying device for processing steel structure columns in buildings, through the design of the scraping mechanism and the collection mechanism, the rotating plate will collide with the outer surface of the collection shell to generate vibration, thereby achieving the effect of accelerating the falling flow of the paint inside the collection shell, making the paint inside the collection shell more concentrated and difficult to dry quickly, avoiding the situation where the thin paint left on the inner wall of the collection shell is easy to dry and difficult to collect.

[0021] 4. This spraying device for processing steel structure columns in buildings, through the design of a scraping mechanism and a collection mechanism working together, causes the counterweight scraper to change angle synchronously during the rotation of the collection shell. At this time, the counterweight scraper will tilt and slide downwards under its own weight, thereby achieving the effect of adhering to the inside of the collection shell and scraping off the paint inside, avoiding waste.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0032] Please see Figure 1-7 The present invention provides a technical solution: a spraying device for processing steel structure columns in buildings, including two bases 1, a support column 2 fixedly connected to the top of each of the two bases 1, a frame 3 fixedly connected between the two support columns 2, a scraping mechanism 4 provided inside the frame 3, a paint storage cylinder 6 fixedly installed on the front of one of the support columns 2, and a spray gun 7 fixedly connected to the front of the paint storage cylinder 6.

[0033] The scraping mechanism 4 includes:

[0034] Motor 401 is fixedly connected to one of the support columns 2 on the outside. Motor 401 is fixedly connected to reciprocating screw 402 through the output end. Reciprocating screw 402 extends into the frame 3. Bearing seat 403 is provided on the outside of reciprocating screw 402. Bearing seat 403 and reciprocating screw 402 are connected by ball nut pair, so that bearing seat 403 can move laterally back and forth on the outer surface of reciprocating screw 402.

[0035] A limit rod 404 is fixedly connected to the rear side of the bearing housing 403. An installation plate 405 is fixedly installed on the top of the bearing housing 403. A fixing rod 406 is fixedly connected to the top of the installation plate 405. A positioning rod 407 is fixedly connected to the top of the fixing rod 406. A collection shell 408 is provided on the top of the positioning rod 407. The positioning rod 407 and the collection shell 408 are movably connected by a damping rotating shaft, which allows the collection shell 408 to rotate under manual assistance.

[0036] A heating plate 409 is fixedly connected to one side of the collection shell 408, so that the heating plate 409 can be moved to perform drying work.

[0037] The reciprocating lead screw 402 is connected to the frame 3 and one of the support columns 2 via bearings, and the positioning rod 407 has a Z-shaped cross-section.

[0038] A limiting groove is provided on the rear side wall of the inner cavity of frame 3, and the limiting rod 404 extends into the limiting groove.

[0039] The collection shell 408 is provided with a collection mechanism 5. The collection mechanism 5 includes multiple guide rods 501. The multiple guide rods 501 are all fixedly connected to the rear side wall of the inner cavity of the frame 3. The cross-section of the multiple guide rods 501 is Z-shaped.

[0040] Two clamping plates 502 are fixedly connected to one side of the collection shell 408. The two clamping plates 502 are distributed in opposite directions, and a rotating rod 503 is rotatably connected between the two clamping plates 502.

[0041] A rotating plate 504 is fixedly connected to the outside of the rotating rod 503, and the cross-section of the rotating plate 504 is arc-shaped.

[0042] Multiple restoring springs 505 are fixedly connected to one side of the collecting shell 408, and one end of each of the multiple restoring springs 505 is fixedly connected to one side of the rotating plate 504.

[0043] The inner walls of the collection shell 408 are provided with arc-shaped grooves, and counterweight scrapers 506 are slidably connected inside the two arc-shaped grooves. The bottom end of the counterweight scraper 506 is in contact with the inside of the collection shell 408.

[0044] When it is necessary to spray paint the steel structure column of the building, the worker first needs to place the steel structure column on top of the support column 2, and then pull out the spray gun 7 and spray the outer surface of the steel structure column.

[0045] During the above-mentioned work process, since the paint sprayed on the outer surface of the steel structure column by the workers is prone to cause excess paint to spread to the sides and bottom, when the paint is concentrated at the lowest point of its outer surface and has not dripped, the workers turn on the motor 401. The operation of the motor 401 will synchronously drive the reciprocating screw 402 to rotate. During the rotation of the reciprocating screw 402, the bearing seat 403 will move laterally on its outside. During the movement of the bearing seat 403, the mounting plate 405 and the fixing rod 406 will move simultaneously. When the fixing rod 406 moves, it will synchronously drive the positioning rod 407 and the collection shell 408 to move. During the movement of the collection shell 408, the concentrated paint on the outside and bottom of the building steel structure column will be scraped off, thereby preventing paint waste and avoiding the need for manual cleaning of the work site.

[0046] During the above process, since the collecting shell 408 will indirectly drive the rotating plate 504 to move, when the rotating plate 504 comes into contact with the guide rod 501, the rotating plate 504 will brush over the outer surface of the guide rod 501. During this process, the restoring spring 505 will be stretched and then restored.

[0047] During the above-mentioned work process, since the collecting shell 408 moves, it also drives the heating plate 409 to move simultaneously. Therefore, when the heating plate 409 moves, it will continuously dry the coating of the already leveled building steel structure column, avoiding the need to wait for a long time to dry, saving workers' time costs, and improving the spraying efficiency of building steel structure columns.

[0048] After the above work is completed, since the bearing housing 403 has completed the linear trajectory of moving to the left, when it starts to move to the right, it will drive the collecting shell 408 to move again. During the movement of the collecting shell 408, it will drive the clamping plate 502 and the rotating rod 503 to move. At this time, the rotating plate 504 will move synchronously. When the rotating plate 504 comes into contact with the guide rod 501, the guide rod 501 will limit the rotating plate 504, so the rotating plate 504 will start to rotate and drive the restoring spring 505 to compress. Then, when the rotating plate 504 completely slides over the outer surface of the guide rod 501, the restoring spring 505 will quickly deform and return to its original shape. During this process, the rotating plate 504 will quickly collide with the outer surface of the collecting shell 408 to generate vibration, thereby achieving the effect of accelerating the falling flow of the coating inside the collecting shell 408, making the coating inside the collecting shell 408 more concentrated and difficult to dry quickly, avoiding the situation where the thin coating left on the inner wall of the collecting shell 408 is easy to dry and difficult to collect.

[0049] After the above work is completed, since the collection shell 408 has returned to its initial position on the far right, the operator needs to turn off the motor 401. Then, the operator needs to rotate the collection shell 408 downwards. At this time, the paint inside the collection shell 408 will be poured out. During this process, as the collection shell 408 rotates, it will simultaneously drive the counterweight scraper 506 to change angle. Therefore, the counterweight scraper 506 will tilt and slide downwards under its own weight, thereby achieving the effect of adhering to the inside of the collection shell 408 and scraping off the paint inside, avoiding waste.

[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
