Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying devices, specifically a spraying device for steel structure processing. Background Technology
[0002] Spraying is an indispensable part of steel structure processing. Its main purpose is to protect the steel structure from corrosion and fire, prevent it from being corroded by chemical substances, extend its service life, or improve its fire resistance rating to prevent it from rapidly losing its load-bearing capacity in a fire.
[0003] In existing technologies, steel structures are generally clamped by fixtures when spraying. However, during use and observation, it has been found that this spraying method can result in the fixtures obscuring the area of the steel structure, leading to uneven spraying. Consequently, the position of the steel structure needs to be adjusted multiple times after spraying, making the spraying operation more cumbersome.
[0004] Therefore, a spraying device for steel structure processing is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A spraying device for steel structure processing, comprising a frame, with multiple spraying mechanisms fixedly installed on the top of the frame; the spraying mechanisms are symmetrically distributed; a hydraulic cylinder is fixedly connected to one side of the frame; a support frame is fixedly connected to the output end of the hydraulic cylinder; a telescopic rod is fixedly connected to the other side of the frame; the telescopic rod and the support frame are both fixedly connected; the support frame and the frame are slidably connected; a steel component is provided on the top of the support frame; both sides of the frame are symmetrically rotatably connected. The device includes fixed pulleys; steel wire ropes are symmetrically fixed to the top of both sides of the support frame; the steel wire ropes and adjacent fixed pulleys are in contact; a connecting frame is fixed to the end of each steel wire rope; the connecting frame and the machine frame are slidably connected; a screw is threaded through the connecting frame; a sliding plate is rotatably connected to the end of the screw; the sliding plate and the connecting frame are slidably connected; through the cooperation of the support frame and the connecting frame, the steel component can be uniformly sprayed without adjusting its position during spraying, thereby improving the convenience of the device when spraying steel components.
[0007] Preferably, the outer wall of the skateboard has multiple positioning grooves; the positioning grooves are equidistant; by setting the positioning grooves, the distance between the skateboard and the inner wall of the steel component can be intuitively judged by observing the positioning grooves, reducing the direct contact between the skateboard and the steel component during adjustment, and reducing the friction and wear between the skateboard and the steel component when the support frame descends.
[0008] Preferably, a heating plate is fixed to the inner wall of the frame; the inner wall of the heating plate is perforated; an air inlet pipe is connected to one side of the heating plate; the heating plate is located at the bottom of the steel component; by setting the heating plate and the air inlet pipe, when spraying the steel component, the air inlet pipe can be connected to a hot air blower, so that the drying airflow can enter the interior of the heating plate through the air inlet pipe and be sprayed out through the holes in the inner wall of the heating plate. These heated airflows can heat the environment around the steel component and accelerate the drying speed of the coating on the surface of the steel component.
[0009] Preferably, a hydrophobic breathable membrane is fixed to the top of the heating plate. By setting the hydrophobic breathable membrane, on the one hand, the liquid coating that drips during the spraying of the steel component surface will fall onto the surface of the hydrophobic breathable membrane. Since the hydrophobic breathable membrane is hydrophobic, the liquid will continue to slide down along the arc surface of the hydrophobic breathable membrane, reducing the contamination of the coating on the inner wall of the heating plate. On the other hand, the hydrophobic breathable membrane will be in an expanded state under the action of airflow, so that the liquid coating on the surface of the hydrophobic breathable membrane will be quickly detached under the guidance of the arc surface, reducing the amount of liquid coating adhering to the surface of the hydrophobic breathable membrane.
[0010] Preferably, a guide plate is fixed to the bottom of the heating plate; a collection trough is provided on the inner wall of the frame; the collection trough is located at the bottom of the guide plate; by setting the guide plate and the collection trough, the liquid coating sliding down the surface of the hydrophobic and breathable membrane will flow into the collection trough under the guidance of the outer wall of the guide plate, which improves the convenience of the device to collect excess coating and facilitates the recycling of coating.
[0011] Preferably, a guide plate is fixed to the top of the collection tank; the outer wall of the guide plate is inclined; by setting the guide plate, the collection area of the collection tank for paint is further expanded, thereby reducing the pollution and waste of other parts caused by paint splashing when it falls into the collection tank.
[0012] The advantages of this utility model are:
[0013] 1. The steel structure processing spraying device of this utility model, through the cooperation of the support frame and the connecting frame, enables the steel components to be uniformly sprayed on the surface without adjusting their position during spraying, thereby improving the convenience of the device when spraying steel components.

Detailed Implementation
[0022] 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 scope of protection of the present utility model.
[0023] Specific implementation examples are given below.
[0024] Please see Figures 1 to 5As shown in the embodiment of this utility model, a spraying device for steel structure processing includes a frame 1, on the top of which a plurality of spraying mechanisms 12 are fixedly installed; the spraying mechanisms 12 are symmetrically distributed; a hydraulic cylinder 13 is fixedly connected to one side of the frame 1; a support frame 15 is fixedly connected to the output end of the hydraulic cylinder 13; a telescopic rod 14 is fixedly connected to the other side of the frame 1; the telescopic rod 14 and the support frame 15 are both fixedly connected; the support frame 15 and the frame 1 are slidably connected; a steel component 16 is provided on the top of the support frame 15; fixed pulleys 17 are symmetrically rotatably connected to both sides of the frame 1; the support... Steel wire ropes 18 are symmetrically fixed to the top of both sides of the frame 15; the steel wire ropes 18 and the adjacent fixed pulleys 17 are in contact; a connecting frame 19 is fixed to the end of the steel wire rope 18; the connecting frame 19 and the frame 1 are slidably connected; a screw 111 is threaded through the connecting frame 19; a sliding plate 110 is rotatably connected to the end of the screw 111; the sliding plate 110 and the connecting frame 19 are slidably connected; during operation, the steel component 16 can be hoisted to the top of the support frame 15 by hoisting equipment, and then the outer wall of the steel component 16 can be sprayed with paint by the spraying mechanism 12, which can be a robot spraying mechanism. The coating can be applied manually or by spraying. After spraying, the hydraulic cylinder 13 can be controlled and activated to lower the support frame 15. When the support frame 15 lowers, it will pull the steel wire rope 18, causing the connecting frame 19 to rise under the pull of the steel wire rope 18. Before the hydraulic cylinder 13 is activated, the screw 111 can be rotated to move it along the connecting frame 19. The sliding plate 110 will also move along the connecting frame 19 along with it. The sliding plate 110 will move with the screw 111. After adjustment, until the sliding plate 110 contacts and supports the inner wall of the steel component 16, the support frame 15 will also detach from the steel component 16. The spraying mechanism 12 can re-spray areas on the surface of the steel component 16 that were not sprayed due to obstruction by the support frame 15, until the surface of the steel component 16 is uniformly sprayed. Then, the hydraulic cylinder 13 can be controlled to lower the steel component 16 onto the surface of the support frame 15, and the screw 111 can be reversed to allow the slide plate 110 to enter the connecting frame 19. Finally, the steel component 16 can be hoisted to the next processing area by the hoisting equipment. Through the cooperation of the support frame 15 and the connecting frame 19, the steel component 16 can be uniformly sprayed without adjusting its position during spraying, thereby improving the convenience of the device when spraying the steel component 16.
[0025] Please see Figure 4As shown, the outer wall of the slide plate 110 is provided with multiple positioning grooves 2; the positioning grooves 2 are equidistantly arranged; by setting the positioning grooves 2, when the screw 111 is rotated to slide the slide plate 110 out of the connecting frame 19, the sliding distance of the slide plate 110 can be quickly determined by observing the number of positioning grooves 2 that have slid out. The spacing between the positioning grooves 2 should be marked on the surface of the slide plate 110, thereby avoiding the situation where the slide plate 110 moves too far and comes into contact with and is squeezed against the inner wall of the steel component 16; by setting the positioning grooves 2, the distance between the slide plate 110 and the inner wall of the steel component 16 can be intuitively determined by observing the positioning grooves 2, reducing the direct contact between the slide plate 110 and the steel component 16 during adjustment, and reducing the friction and wear between the slide plate 110 and the steel component 16 when the support frame 15 descends.
[0026] Please see Figure 5 As shown, a heating plate 3 is fixed to the inner wall of the frame 1; the inner wall of the heating plate 3 is perforated; an air inlet pipe 32 is connected to one side of the heating plate 3; the heating plate 3 is located at the bottom of the steel component 16; by setting the heating plate 3 and the air inlet pipe 32, when spraying the steel component 16, the air inlet pipe 32 can be connected to a hot air blower, so that the drying airflow can enter the interior of the heating plate 3 through the air inlet pipe 32 and be sprayed out through the holes in the inner wall of the heating plate 3. These heated airflows can heat the environment around the steel component 16 and accelerate the drying speed of the coating on the surface of the steel component 16.
[0027] Please see Figure 5 As shown, a hydrophobic breathable membrane 4 is fixed to the top of the heating plate 3. By setting the hydrophobic breathable membrane 4, on the one hand, the liquid paint that drips when the steel component 16 is sprayed will fall onto the surface of the hydrophobic breathable membrane 4. Since the hydrophobic breathable membrane 4 is hydrophobic, the liquid will continue to slide down along the arc surface of the hydrophobic breathable membrane 4, reducing the contamination of the inner wall of the heating plate 3 by the paint. On the other hand, the hydrophobic breathable membrane 4 will be in an expanded state under the action of airflow, so that the liquid paint on the surface of the hydrophobic breathable membrane 4 will quickly detach under the guidance of the arc surface, reducing the amount of liquid paint adhering to the surface of the hydrophobic breathable membrane 4.
[0028] Please see Figure 5 As shown, a guide plate 5 is fixedly connected to the bottom of the heating plate 3; a collection trough 52 is provided on the inner wall of the frame 1; the collection trough 52 is located at the bottom of the guide plate 5; by setting the guide plate 5 and the collection trough 52, the liquid coating that slides down the surface of the hydrophobic breathable membrane 4 will flow into the collection trough 52 under the guidance of the outer wall of the guide plate 5, which improves the convenience of the device to collect excess coating and facilitates the recycling of coating by the device.
[0029] Please see Figure 2As shown, a guide plate 6 is fixed to the top of the collection tank 52; the outer wall of the guide plate 6 is inclined; by setting the guide plate 6, the collection area of the collection tank 52 for paint is further expanded, thereby reducing the pollution and waste of other parts caused by paint splashing when it falls into the collection tank 52.
[0030] Working principle: The steel component 16 is hoisted to the top of the support frame 15 by hoisting equipment. Then, the outer wall of the steel component 16 is sprayed with paint by the spraying mechanism 12, which can be either robotic or manual. After spraying, the support frame 15 is lowered by controlling and activating the hydraulic cylinder 13. When the support frame 15 lowers, it pulls the wire rope 18, causing the connecting frame 19 to rise under the pull of the wire rope 18. Before the hydraulic cylinder 13 is activated, the screw 111 can be rotated to move it along the connecting frame 19. The sliding plate 110 will also move along the connecting frame 19 along with the screw 111. After adjustment, the sliding plate 110 and the steel component 16 are aligned. The inner wall contacts and supports the steel component 16. At this time, the support frame 15 will also detach from the steel component 16. Then, the spraying mechanism 12 can spray the areas on the surface of the steel component 16 that were not sprayed due to the obstruction of the support frame 15 until the surface of the steel component 16 is evenly sprayed. Then, the hydraulic cylinder 13 can be controlled to make the steel component 16 fall onto the surface of the support frame 15, and the screw 111 is reversed to make the slide plate 110 enter the interior of the connecting frame 19. Finally, the steel component 16 can be hoisted to the next processing area by the hoisting equipment. By setting the positioning groove 2, when the screw 111 is rotated to slide the slide plate 110 out of the interior of the connecting frame 19, the sliding distance of the slide plate 110 can be quickly judged by observing the number of positioning grooves 2 that slide out. The spacing between the positioning grooves 2 should be marked on the slide plate. The surface of the 110 plate is designed to prevent the sliding plate 110 from traveling too far and coming into contact with and being squeezed against the inner wall of the steel component 16. By setting up a heating plate 3 and an air inlet pipe 32, when spraying the steel component 16, the air inlet pipe 32 can be connected to a hot air blower, allowing the drying airflow to enter the interior of the heating plate 3 through the air inlet pipe 32 and be sprayed out through the holes in the inner wall of the heating plate 3. This heated airflow can heat the surrounding environment of the steel component 16, accelerating the drying speed of the coating on the surface of the steel component 16. By setting up a hydrophobic breathable membrane 4, the liquid coating that drips during spraying of the steel component 16 will fall onto the surface of the hydrophobic breathable membrane 4. Because the hydrophobic breathable membrane 4 is hydrophobic, the liquid will continue to flow along the curved surface of the hydrophobic breathable membrane 4. The sliding action of the guide plate 5 and the collection tank 52 reduces the contamination of the inner wall of the heating plate 3 by the coating. On the other hand, the hydrophobic breathable membrane 4 will expand under the action of airflow, allowing the liquid coating on the surface of the hydrophobic breathable membrane 4 to quickly detach under the guidance of the curved surface, reducing the amount of liquid coating adhering to the surface of the hydrophobic breathable membrane 4. By setting the guide plate 5 and the collection tank 52, the liquid coating sliding down the surface of the hydrophobic breathable membrane 4 will flow into the collection tank 52 under the guidance of the outer wall of the guide plate 5, improving the convenience of the device to collect excess coating and facilitating the recycling of coating. By setting the guide plate 6, the collection area of the collection tank 52 is further expanded, thereby reducing the contamination and waste of other components caused by the splashing of coating when it falls into the collection tank 52.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
