Description

Technical Field

[0001] This utility model relates to the field of cable tray spraying technology, specifically to a device for uniformly spraying anti-corrosion coatings on cable trays. Background Technology

[0002] Cable trays, as important support and protection facilities in power systems, are widely used in various buildings and industrial sites. Because cable trays are often in environments with moisture, corrosive gases, or chemicals, their surfaces are easily corroded, affecting their structural strength and service life. To improve the corrosion resistance of cable trays, it is usually necessary to spray an anti-corrosion coating on their surface. The nozzle position on traditional spraying equipment is fixed, and because the angle is difficult to adjust, it can only spray cable trays of a specific width. When the cable tray is narrow (that is, the length of the pipe is greater than the width of the cable tray), the anti-corrosion coating sprayed on both sides of the pipe is easy to adhere to other parts of the spraying box, resulting in waste and increased spraying costs. Utility Model Content

[0003] The purpose of this invention is to provide a uniform spraying device for anti-corrosion coating of cable trays to solve the problems mentioned in the background art.

[0016] 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.

[0017] Please see Figures 1 to 3 This utility model provides a uniform spraying device for anti-corrosion coating of cable trays, including a spraying box 1. A chute 2 is provided on the top of the spraying box 1, and a storage tank 3 is fixedly connected to the spraying box 1. A discharge port is fixedly connected to the rear surface of the spraying box 1 to facilitate the discharge of excess anti-corrosion coating. A centrifugal pump 4 is fixedly connected to the top of the storage tank 3. A sliding mechanism 5 is installed above the chute 2. The sliding mechanism 5 includes a first baffle 51, a second baffle 52, and an adjusting block 53. The first baffle 51 and the second baffle 52 are fixedly connected to the top of the spraying box 1. A first servo motor 511 is fixedly connected to the first baffle 51. The drive end of the first servo motor 511 passes through the first baffle 51 and is fixedly connected to a first screw 512. An adjusting block 53 is fitted with an external thread. A horizontal plate 54 is fixedly connected to the adjusting block 53. A limiting groove 541 passes through the interior of the horizontal plate 54. A first support plate 55 and a second support plate 56 are fixedly connected to the top of the limiting groove 541. A second servo motor 551 is fixedly connected to the first support plate 55. The drive end of the second servo motor 551 passes through the first support plate 55 and is fixedly connected to a second screw 552. A rack 57 is fitted with an external thread on the second screw 552. A gear 58 meshes with the rack 57. A transmission shaft 581 passes through the interior of the gear 58. A pipe 582 is fixedly connected to the bottom end of the transmission shaft 581. Multiple sets of nozzles 583 are fixedly connected to the bottom of the pipe 582. A limiting block 59 is fixedly connected to the bottom of the rack 57.

[0018] Furthermore, one end of the first screw 512 is rotatably connected to the second baffle 52 via a bearing, and one end of the second screw 552 is rotatably connected to the second support plate 56 via a bearing. The first screw 512 and the second screw 552 are perpendicular to each other, which realizes the precise positioning of the nozzle 583 in the horizontal direction and the flexible adjustment of the spraying angle, thereby adapting to the actual spraying of narrow cable trays and avoiding paint waste.

[0019] Furthermore, the limiting block 59 and the limiting groove 541 are adapted to each other. The limiting block 59 is slidably connected inside the limiting groove 541 to ensure the stability of the rack 57 during movement and to ensure that the meshing transmission of the gear 58 is accurate and reliable, thereby making the rotation and spraying action of the nozzle 583 more precise.

[0020] Furthermore, the drive shaft 581 passes through the horizontal plate 54, and the drive shaft 581 and the horizontal plate 54 are rotatably connected by bearings, so that when the gear 58 drives the pipe 582 and the nozzle 583 to rotate more smoothly, it avoids jamming, ensures that the spraying angle can be flexibly adjusted, and further improves the uniformity of coating coverage.

[0021] Furthermore, a slider is fixed to the bottom of the adjusting block 53. The slider is slidably connected inside the slide groove 2 to enhance the stability of the horizontal plate 54, the pipe 582 and the nozzle 583 when they move back and forth, and to prevent uneven spraying caused by vibration or offset.

[0022] Furthermore, the inlet end of the centrifugal pump 4 is fixedly connected to the storage tank 3, and the outlet end of the centrifugal pump 4 is fixedly connected to the pipeline 582 through a hose, ensuring a continuous and stable supply of paint. At the same time, the flexible design of the hose does not restrict the freedom of movement of the nozzle 583, ensuring the continuity and efficiency of the spraying process.

[0023] The first servo motor 511 and the second servo motor 551 are both model ACSM110-G04030LZ.

[0024] Working principle: The cable tray is placed in the spray box 1. The centrifugal pump 4 draws anti-corrosion coating from the storage tank 3 and delivers it to the pipe 582 through a hose. Finally, it is sprayed out by multiple sets of nozzles 583. The first servo motor 511 starts, driving the first screw 512 to rotate. The adjusting block 53 moves laterally along the first screw 512 through threaded engagement, causing the horizontal plate 54, pipe 582, and nozzles 583 to slide on the slide groove 2, thereby adjusting the lateral position of the nozzles 583 so that the anti-corrosion coating is evenly sprayed on the cable tray. When the length of the horizontally set pipe 582 is greater than the width of the cable tray, the second servo motor 551 starts, driving the second screw 552 to rotate. The rack 57 moves laterally along the slide groove 2 through threaded engagement. The second screw 552 moves, driving the gear 58 meshing with it to rotate. The gear 58 drives the pipe 582 and the nozzle 583 to rotate through the transmission shaft 581. The pipe 582 and the nozzle 583 then tilt to spray, thereby adjusting the spray angle of the pipe 582 and the nozzle 583. At this time, all the nozzles 583 are positioned above the cable tray to adapt to the actual spraying of the narrower cable tray. The limiting block 59 slides in the limiting groove 541 to ensure the stability of the rack 57 when it moves. The slider at the bottom of the adjusting block 53 slides in the sliding groove 2 to ensure the smoothness of the lateral movement. Through the synergistic effect of lateral movement and angle adjustment, it can be used for spraying on narrower cable trays, avoiding paint waste.
