Description
Technical Field
[0001] This invention belongs to the field of construction tools for steel structures, and specifically relates to a device and method for spraying paint on straight railings. Background Technology
[0002] During the paint spraying process, the first step is to place the railings on the painting site. As we all know, railings are lightweight, occupy a large area, and are basically required in various projects. Therefore, designing a suitable placement tool is very important and is also an important means to solve site problems and improve construction efficiency.
[0003] In existing technologies, most railing painting fixtures consist of two supports with a crossbeam at the top. Multiple hooks are arranged in a row on the crossbeam, and each hook has a pulley fixed to its upper part. The pulleys slide horizontally within a groove on the bottom of the crossbeam. A base is located on the ground below the crossbeam, and a turntable is mounted on the base. The turntable has an upward-extending baffle located in front of or behind the hooks. A guide plate is located on the lower part of the front side of the baffle, and a recovery trough is located below the guide plate on the turntable. This type of device has drawbacks; paint cannot be sprayed at the hook positions, resulting in missed areas, affecting the overall appearance quality and the lifespan of the paint. Therefore, this type of painting device still needs further improvement and optimization. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide an apparatus and method for spraying paint on straight railings, which solves the problem in the prior art that the paint on straight railings is prone to local missed areas, resulting in missed coating and thus the inability to guarantee the quality of the railings.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A device for spray painting straight railings includes a base, and several rows of round steel uprights arranged in a stepped manner in the vertical direction on the base. The spacing between each row of round steel uprights is equal to the spacing between the uprights of the straight railing, and the round steel uprights between adjacent rows are staggered in the horizontal direction.
[0007] Each round steel upright is equipped with a barrier at its lower end. The barriers of each row of round steel uprights are located on the same horizontal line, while the barriers of adjacent rows of round steel uprights are located on different horizontal lines.
[0008] The guardrail is made of round steel welded to both sides of the lower end of a round steel upright.
[0009] The top of the round steel pole is designed with a tapered structure.
[0010] A certain distance is maintained between adjacent rows of round steel uprights.
[0011] The spacing between two adjacent rows of round steel uprights is 70-90mm.
[0012] The diameter of the round steel upright is 8 to 12 mm smaller than the diameter of the straight railing upright.
[0013] A method for spray painting straight railings specifically includes the following steps:
[0014] Step 1: Set up a row of round steel uprights on the painting platform according to the spacing of the straight railing uprights. The number and spacing of the round steel uprights are the same as those of the straight railing uprights.
[0015] Step 2: Install guardrails at a predetermined distance from the top of the round steel pole, ensuring all guardrails are on the same horizontal line;
[0016] Step 3: Install a second row of round steel uprights parallel to the first row at a certain interval. The second row of round steel uprights is horizontally offset from the first row of round steel uprights by at least one round steel diameter.
[0017] Step 4: Apply the method in Step 2 to set up the barrier for the second row of round steel uprights;
[0018] Step 5: Starting from the third row, repeat steps 3 and 4 until all rows of round steel uprights are installed;
[0019] Step 6: Connect the uprights of the straight railings one by one to the round steel uprights, and complete the placement of all the straight railings in sequence;
[0020] Step 7: Start the painting equipment and paint all the straight railings. During the painting process, adjust the direction of the spray nozzle in real time to ensure that the outer surface of the straight railings is painted evenly.
[0021] Each row of round steel uprights is fitted with a corresponding straight railing.
[0022] The top of the round steel pole is machined into a tapered structure, and the diameter of the tapered tip is 8-12mm.
[0023] Compared with the prior art, the present invention has the following beneficial effects:
[0024] 1. The painting device of the present invention adopts a vertically stepped distribution and a horizontally staggered arrangement, which makes the painting of the straight railing uniform and without any missed areas.
[0025] 2. The painting device of the present invention directly connects the straight railing uprights to the round steel uprights, ensuring that the railings can be erected, thereby improving the painting quality and work efficiency.
[0026] 3. It solves the problem of poor coating quality in finished railings and saves a significant amount of time during the coating process.

[0033] The markings in the diagram are: 1-base; 2-round steel upright; 3-guardrail to stop vehicles; 4-straight guardrail upright. Detailed Implementation
[0034] The structure and working process of the present invention will be further described below with reference to the accompanying drawings.
[0035] Based on the characteristics of the railing, the uprights are all made of straight-seam pipes, and after the finished railing is assembled and welded, the uprights are not sealed. The railing is usually 6 meters long and 1.2 meters high. Both the horizontal bars and uprights are made of steel pipes and are not enclosed. Therefore, we thought of using pins for fixing.
[0036] Therefore, several round steel bars are erected on the paint spraying platform. These bars are supported vertically by the steel pipe uprights of the railing, ensuring the railing stands upright. To prevent the railing from falling directly onto the platform, two round steel guide rails are welded to each steel bar. The guide rails on each row of steel bars are on the same horizontal line. The guide rails on adjacent rows are not on the same line, creating a height difference. This ensures that the kick plates and crossbars of each railing section are not obstructed by the railing in front, allowing several railing sections to be painted at once. This method eliminates the need to reverse the railing, allowing the paint to be applied to both sides of the railing in one go.
[0037] A device for spray painting straight railings includes a base, and several rows of round steel uprights arranged in a stepped manner in the vertical direction on the base. The spacing between each row of round steel uprights is equal to the spacing between the uprights of the straight railing, and the round steel uprights between adjacent rows are staggered in the horizontal direction.
[0038] Specific embodiments, such as Figures 1 to 6 As shown,
[0039] A device for spray painting straight railings includes a base 1, and several rows of round steel poles 2 arranged in a stepped manner in the vertical direction on the base. The spacing between each row of round steel poles 2 is equal to the spacing between the railing poles 4, and the round steel poles 2 of adjacent rows are staggered in the horizontal direction.
[0040] This railing spraying device is simple to manufacture. The specifications of the round steel used in the device are determined by the specifications of the railing upright steel pipes. The specifications of commonly used railing uprights are as follows: Select The uprights of the round steel fabrication device are arranged in 16 rows. Each row has 6 round steel bars, and the spacing between the round steel bars is arranged according to the spacing between the railing uprights. The spacing between the railing uprights is 1 meter, so the spacing between two adjacent round steel bars in each row is 1 meter.
[0041] The first row of round steel uprights in this device is 600mm high, and welding is done on both sides at a position 500mm from the top of the uprights. Round steel bars are used as guardrails and wheel stops. The top 100mm of the round steel uprights are machined into a tapered shape, with a diameter of [missing information - likely a diameter value]. One railing can be placed in each row.
[0042] The second row of round steel uprights is 660mm high, 60mm higher than the first row. This height is determined by the width of the kick plate to prevent the kick plate of the first row from obstructing the kick plate of the second row. Also, like the first row, welds are made on both sides at a position 500mm from the top of the round steel uprights. Round steel bars are used as guardrails and wheel stops. The top 100mm of the round steel uprights are machined into a tapered shape, with a diameter of [missing information - likely a diameter value]. The second row of uprights is 80mm vertically and 80mm horizontally from the first row. This is to prevent the second row of railings from being obstructed by the first row during the painting process. Alternatively, one railing panel can be placed in the second row.
[0043] The arrangement of the third to the last row is the same as that of the second row.
[0044] Each round steel upright is equipped with a guardrail 3 at its lower end. The guardrails of each row of round steel uprights are located on the same horizontal line, while the guardrails of adjacent rows of round steel uprights are located on different horizontal lines.
[0045] The guardrail is made of round steel welded to both sides of the lower end of a round steel upright.
[0046] The top of the round steel pole is designed with a tapered structure.
[0047] A certain distance is maintained between adjacent rows of round steel uprights.
[0048] The spacing between two adjacent rows of round steel uprights is 70-90mm.
[0049] The diameter of the round steel upright is 8 to 12 mm smaller than the diameter of the straight railing upright.
[0050] The round steel uprights at both ends of the same row are taller than the round steel uprights in the middle, which makes it easier for the straight railings to be placed more firmly on the support.
[0051] A method for painting straight railings involves fixing the straight railings using the aforementioned straight railing painting device, followed by a painting operation. The method specifically includes the following steps:
[0052] Step 1: Set up a row of round steel uprights on the painting platform according to the spacing of the straight railing uprights. The number and spacing of the round steel uprights are the same as those of the straight railing uprights.
[0053] Step 2: Install guardrails at a predetermined distance from the top of the round steel pole, ensuring all guardrails are on the same horizontal line;
[0054] Step 3: Install a second row of round steel uprights parallel to the first row at a certain interval. The second row of round steel uprights is horizontally offset from the first row of round steel uprights by at least one round steel diameter.
[0055] Step 4: Apply the method in Step 2 to set up the barrier for the second row of round steel uprights;
[0056] Step 5: Starting from the third row, repeat steps 3 and 4 until all rows of round steel uprights are installed;
[0057] Step 6: Connect the uprights of the straight railings one by one to the round steel uprights, and complete the placement of all the straight railings in sequence;
[0058] Step 7: Start the painting equipment and paint all the straight railings. During the painting process, adjust the direction of the spray nozzle in real time to ensure that the outer surface of the straight railings is painted evenly.
[0059] Each row of round steel uprights is fitted with a corresponding straight railing.
[0060] The top of the round steel pole is machined into a tapered structure, and the diameter of the tapered tip is 8-12mm.
[0061] In this spraying method, all specific parameters can be referenced from the parameters of the aforementioned device. Those skilled in the art can make adaptive changes based on the site conditions and construction requirements, and are not limited to the listed data. This method primarily provides a design scheme and does not require specific data; those skilled in the art can still construct the necessary device.
[0062] The device of the present invention has the following advantages:
[0063] This invention provides a fixture for batch painting of railings, which allows for effective staggering of front and rear railings without obstruction, thus solving the problem of large space requirements for railing painting. Using this fixture significantly reduces the space needed for batch railing painting and avoids defects such as repeated spraying, missed areas, and uneven spraying. Furthermore, this fixture makes it particularly easy to position and fix the railings, saving considerable time and improving painting efficiency. This fixture can be used for paint spraying in similar railing painting processes, and its market application prospects are very broad.
