Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically a steel structure spraying and turning frame. Background Technology

[0002] Steel structures are structures composed of steel materials, mainly including round steel pipes and square steel pipes. Steel structures are one of the main types of building structures, characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation. Steel structures are prone to corrosion, so a layer of paint needs to be sprayed on the surface of the steel structure. In order to facilitate comprehensive and rapid spraying of the components of the steel structure, a spraying turnover frame is often required for implementation.

[0003] Existing technology, such as publication number CN221245709U, provides a steel structure spraying tilting frame, including a frame. A tilting mechanism and a spraying mechanism are mounted on the upper end of the frame. The tilting mechanism includes two tilting parts, each comprising a fixing ring, a rotating disk, and multiple screws. The rotating disk is rotatably mounted inside the fixing ring, and the multiple screws are evenly threaded through the rotating disk. This invention, through the arrangement of multiple screws, allows for flexible fixation of the steel structure at multiple positions, improving the stability of the steel structure during tilting and thus ensuring stable painting. By coordinating a distance sensor and a lifting drive device, the distance sensor can detect the distance to the steel structure directly below the spray gun in real time, and the lifting drive device can adjust the height of the spray gun in real time, ensuring that the distance between the spray gun and the steel structure surface remains consistent during spraying, thereby improving the uniformity of the spray.

[0004] Existing painting equipment often uses exposed components for clamping and securing the ends of steel structures, lacking necessary shielding. This results in paint mist easily accumulating on the clamping mechanism during painting, causing it to jam and requiring frequent cleaning. Therefore, we propose a steel structure painting tilting frame. Utility Model Content

[0005] The purpose of this utility model is to provide a steel structure spray painting turning frame, which solves the problem that paint mist easily disperses and accumulates on the clamping mechanism during the painting process, causing the mechanism to jam and requiring frequent cleaning.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A steel structure spray painting turning frame includes a base, a rotating ring rotatably connected to the top of the base, and a stepper motor for driving the rotating ring to rotate is provided inside the base;

[0008] The top of the rotating ring is provided with a rotating mechanism for driving the pipe to rotate;

[0009] A spraying mechanism is provided at the center of the rotating ring for spraying the pipe.

[0010] The rotating mechanism includes a rotating cylinder, which is rotatably connected to the top of the rotating ring. Several rotating cylinders are provided. A support rod is fixed to the top of the rotating cylinder. The support rod is a hollow rod, and abutment blocks are slidably connected to the four sides of the support rod to abut against the inner wall of the pipe for fixation.

[0011] Preferably, the outer wall of each rotating drum is fixedly connected with a driven wheel, and the outer wall of the base is fixedly connected with an arc-shaped rack for engaging the driven wheel.

[0012] Preferably, the abutment block has a locking block at one end inside the support rod, and the position where the abutment block contacts the inner wall of the pipe is arc-shaped.

[0013] Preferably, a piston rod is slidably connected to the inner wall of the rotating cylinder, and a spring is fixedly connected between the bottom of the piston rod and the inner wall of the rotating cylinder.

[0014] Preferably, the inner wall of the piston rod has a through hole for connecting the inside of the rotating cylinder and the support rod.

[0015] Preferably, the length of the arc-shaped rack is longer than the circumference of the driven wheel.

[0016] Preferably, the spraying mechanism includes a spray pipe, which is fixedly connected to the top of the rotating ring at the position corresponding to each support rod, and a row of spray heads is fixedly connected to one side of each spray pipe corresponding to the support rod. A solenoid valve is provided on the spray pipe.

[0017] By employing the above technical solution, this utility model provides a steel structure spraying and turning frame. It possesses at least the following beneficial effects:

[0018] I. This utility model uses a method where the pipe is fitted onto each support rod and fixed to the inner wall of the pipe by abutting blocks. This method can hide the pipe fixing mechanism and avoid the problem of a large amount of paint adhering to the fixing pipe structure during spraying, which could cause it to jam or even fail. Furthermore, the rotating ring can be driven by a stepper motor to switch between different pipes for spraying. Because the arc-shaped rack meshes with the driven wheel, when the spraying mechanism is spraying the pipe, the driven wheel drives the support rod above the rotating drum to rotate together with the fixed pipe, so as to facilitate comprehensive spraying of the pipe.

[0019] II. In this utility model, because the inner wall of the rotating cylinder is slidably connected to a piston column, when the pipe is sleeved on the outer wall of the support rod, the weight of the pipe will press on the top of the piston column, causing the piston column to sink into the inside of the rotating cylinder. This forces the air inside the rotating cylinder into the support rod, and the increased pressure of the support rod will squeeze out the abutment block and abut against the inner wall of the pipe, so as to facilitate the fixing of the pipe.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] A steel structure spray painting and turning frame, such as Figure 1 - Figure 4As shown, the device includes a base 1, with a rotating ring 2 rotatably connected to the top of the base 1. A stepper motor is installed inside the base 1 to drive the rotating ring 2. A rotating mechanism 3 is installed on the top of the rotating ring 2 to drive the pipe to rotate. A spraying mechanism 4 is located at the center of the rotating ring 2 to spray the pipe. The rotating mechanism 3 includes rotating cylinders 31, which are rotatably connected to the top of the rotating ring 2. Several rotating cylinders 31 are provided. A support rod 32 is fixed to the top of the rotating cylinder 31. The support rod 32 is a hollow rod, and four sides of the support rod 32 are slidably connected to abutment blocks 321 to abut against the inner wall of the pipe for fixation. The method of setting abutment blocks 321 on four sides allows the pipe to be fixed, whether it is a square or round pipe. The outer wall of the rotating drum 31 is fixedly connected to the driven wheel 33, and the outer wall of the base 1 is fixedly connected to the arc-shaped rack 34 for meshing with the driven wheel 33. The length of the arc-shaped rack 34 is longer than the circumference of the driven wheel 33 to ensure that the driven wheel 33 will rotate at least one full turn when it passes the position of meshing with the arc-shaped rack 34. The end of the abutment block 321 inside the support rod 32 is provided with a locking block to prevent the abutment block 321 from disengaging from the support rod 32. The position where the abutment block 321 contacts the inner wall of the pipe is set with an arc surface.

[0028] In this embodiment, during actual processing, the pipe is fitted onto each support rod 32, and the pipe is fixed by abutting the inner wall of the pipe with abutting block 321. This method can hide the pipe fixing mechanism and avoid the problem of a large amount of paint adhering to the fixing pipe structure during spraying, which could cause it to jam or even fail. Furthermore, the rotating ring 2 can be driven by a stepper motor to switch between different pipes for spraying. When the support rod 32 moves to the position of the arc-shaped rack 34, the spraying mechanism 4 starts spraying the pipe, and stops spraying when the support rod 32 leaves the position of the arc-shaped rack 34. Since the arc-shaped rack 34 is meshed with the driven wheel 33, when the spraying mechanism 4 is spraying the pipe, the driven wheel 33 drives the support rod 32 above the rotating drum 31 to rotate together with the pipe, so as to facilitate comprehensive spraying of the pipe.

[0029] like Figure 4 As shown, preferably, a piston column 311 is slidably connected to the inner wall of the rotating cylinder 31, and a spring 312 is fixedly connected between the bottom of the piston column 311 and the inner wall of the rotating cylinder 31. A through hole 322 is opened on the inner wall of the piston column 311 to connect the interior of the rotating cylinder 31 and the support rod 32.

[0030] In this embodiment, since the inner wall of the rotating cylinder 31 is slidably connected to the piston column 311, when the pipe is sleeved on the outer wall of the support rod 32, the weight of the pipe will press on the top of the piston column 311, causing the piston column 311 to sink into the interior of the rotating cylinder 31. This causes the air inside the rotating cylinder 31 to be squeezed into the support rod 32. The increased pressure of the support rod 32 will squeeze out the abutment block 321 and abut against the inner wall of the pipe, so as to facilitate the fixing of the pipe.

[0031] like Figure 1 , Figure 2 As shown, the spraying mechanism 4 includes a spray pipe 41, which is fixedly connected to the top of the rotating ring 2 at the position corresponding to each support rod 32. Each spray pipe 41 is fixedly connected to a row of spray heads 42 on one side corresponding to the support rod 32. A solenoid valve is provided on the spray pipe 41.

[0032] In this embodiment, the spraying mechanism 4 opens the solenoid valve of the corresponding spray pipe 41 when the pipe passes the position of the arc-shaped rack 34, so as to facilitate spraying the pipe through the spray head 42. When the pipe leaves the position of the arc-shaped rack 34, the solenoid valve of the spray pipe 41 closes.

[0033] In the actual processing of this utility model, a steel structure spraying and turning frame is used. The pipe is fitted onto each support rod 32. Because a piston column 311 is slidably connected to the inner wall of the rotating cylinder 31, when the pipe is fitted onto the outer wall of the support rod 32, the weight of the pipe presses down on the top of the piston column 311, causing the piston column 311 to sink into the interior of the rotating cylinder 31. This forces air inside the rotating cylinder 31 into the support rod 32. The increased pressure on the support rod 32 forces the abutment block 321 to be squeezed out and abut against the inner wall of the pipe, facilitating the fixing of the pipe and enabling… The rotating ring 2 is driven by a stepper motor to switch between different pipes for spraying. When the pipe passes the position of the arc-shaped rack 34, the solenoid valve of the corresponding spray pipe 41 is opened to facilitate spraying of the pipe through the spray head 42. When it leaves the position of the arc-shaped rack 34, the solenoid valve of the spray pipe 41 is closed. Since the arc-shaped rack 34 is meshed with the driven wheel 33, when the spraying mechanism 4 sprays the pipe, the driven wheel 33 drives the support rod 32 above the rotating drum 31 to rotate together with the pipe to facilitate comprehensive spraying of the pipe.
