Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel grating technology, and in particular to a steel grating anti-rust coating device. Background Technology
[0002] Steel grating is a steel product made of flat steel bars arranged at certain intervals and crossbars, welded together to form a grid with square openings. It is also called steel grating or grid panel. When steel grating is used in humid and highly corrosive environments, such as chemical plants, seaside locations, and sewage treatment plants, even after hot-dip galvanizing, it may require further anti-corrosion coating to enhance its corrosion resistance.
[0003] However, during the rust-proofing and oiling process of existing steel gratings, the existing oiling equipment cannot effectively and evenly apply the rust-proofing oil layer to the edges and corners of the internal mesh of the steel grating. Therefore, when the steel grating is used in a humid environment, the edges and corners of the internal mesh of the steel grating will be the first to show rust marks if no oil layer is applied, thus reducing the service life of the steel grating. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rust-proofing and oiling device for steel grating.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A steel grating anti-rust oiling device includes an operating table. A rectangular through-slot is formed on the top outer wall of the operating table, and an oiling roller brush is rotatably installed on the inner wall of the rectangular through-slot. A fixed support plate is fixed to one end of the operating table by bolts, and a connecting pipe is rotatably installed on one side of the fixed support plate. One end of the connecting pipe is connected to a rectangular square tube, and the bottom inner wall of the rectangular square tube is connected to equally spaced nozzles. An oil injection pipe is rotatably connected to the end of the connecting pipe. An electric telescopic rod is fixed to one end of the operating table, and a rectangular top plate is connected to the piston rod at the top of the electric telescopic rod. A synchronous pulley is rotatably connected to the top outer wall of the rectangular top plate, and a synchronous belt meshes with the outer wall of the synchronous pulley. A drive motor is connected to the top axis of one of the synchronous pulleys.
[0007] As a further embodiment of this utility model: a first side brush baffle is fixed on one side of the top of the operating table along the length direction, and a second side brush baffle is fixed on the other side of the top of the operating table along the length direction.
[0008] As a further improvement of this utility model: a gear is welded to the outer wall of the middle part of the connecting pipe, and a sector gear is meshed and driven at the bottom of the gear, and a servo motor output shaft is connected to the axis of the sector gear.
[0009] As a further embodiment of this utility model: an oiling brush roller is fixed at the bottom shaft of the synchronous pulley, and the size of the oiling brush roller is adapted to the size of the steel grating.
[0010] As a further embodiment of this utility model: symmetrically distributed balance rods are welded to the bottom outer wall of the rectangular top plate, and symmetrically distributed insertion holes are opened through the top outer wall of the operating table, the inner wall size of the insertion holes being adapted to the size of the balance rods.
[0011] As a further embodiment of this utility model: a sprocket is fixed to the end of the oiling roller brush, and a chain is engaged on the outer wall of the sprocket, and one of the sprockets is connected to a reduction motor.
[0012] Compared with the prior art, the present invention provides a rust-proof oiling device for steel grating, which has the following beneficial effects:
[0013] The steel grating anti-rust oiling device designed in this paper can quickly adapt to steel gratings of different sizes and limit their movement by adjusting the distance between the first side brush baffle and the second side brush baffle. In conjunction with the oiling roller brush at the bottom, it can effectively and evenly coat the outer wall of the steel grating with oil.
[0014] The anti-corrosion oiling device for steel grating designed in this way uses a continuously oscillating nozzle set on the top of the steel grating to spray oil, which allows the anti-corrosion oil to be evenly distributed on the outer wall of the steel grating. In addition, the oiling brush roller, which is constantly adjusted up and down and rotated, is precisely inserted into the grid holes of the steel grating, which can evenly apply the anti-corrosion oil to the edges and corners of the grid, thus extending the service life of the steel grating.
[0015] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example
[0021] A rust-proof coating device for steel grating, in this embodiment, as follows: Figure 1-3 As shown, the system includes an operating table 1. A rectangular through-slot 2 is formed through the top outer wall of the operating table 1, and an oiling roller brush 3 is rotatably installed on the inner wall of the rectangular through-slot 2. A fixed support plate 6 is fixed to one end of the operating table 1 by bolts, and a connecting pipe 7 is rotatably installed on one side of the fixed support plate 6. One end of the connecting pipe 7 is connected to a rectangular square tube 8, and the bottom inner wall of the rectangular square tube 8 is connected to nozzles 9 distributed at equal intervals. An oil injection pipe is rotatably connected to the end of the connecting pipe 7. An electric telescopic rod 13 is fixed to one end of the operating table 1, and a rectangular top plate 14 is connected to the piston rod at the top of the electric telescopic rod 13. A synchronous pulley 15 is rotatably connected to the top outer wall of the rectangular top plate 14, and a synchronous belt 16 meshes with the outer wall of the synchronous pulley 15. A drive motor 18 is connected to the top axis of one of the synchronous pulleys 15.
[0022] By adjusting the distance between the first side brush baffle 4 and the second side brush baffle 5 set on the side, the oiling device can quickly adapt to steel gratings of different sizes for positioning, and in conjunction with the oiling roller brush 3 at the bottom, it can effectively and evenly coat the outer wall of the steel grating with oil.
[0023] A first side brush baffle 4 is fixed on one side of the top of the operating table 1 along the length direction, and a second side brush baffle 5 is fixed on the other side of the top of the operating table 1 along the length direction. A gear 10 is welded to the outer wall of the middle part of the connecting pipe 7, and a sector gear 11 is meshed and driven at the bottom of the gear 10. The output shaft of the servo motor 12 is connected to the axis of the sector gear 11.
[0024] An oiling brush roller 17 is fixed at the bottom axis of the synchronous pulley 15, and the size of the oiling brush roller 17 is adapted to the size of the steel grating.
[0025] The end of the oiling roller brush 3 is fixed with a sprocket, and a chain is engaged on the outer wall of the sprocket. One of the sprockets is connected to a reduction motor.
[0026] By spraying oil with a constantly oscillating nozzle 9 on the top of the steel grating, the anti-corrosion oil can be evenly distributed on the outer wall of the steel grating. In conjunction with the oiling brush roller 17, which is constantly adjusted up and down and rotated, it can be precisely inserted into the grid holes of the steel grating, so that the anti-corrosion oil can be evenly applied to the edges and corners of the grid mesh, thus extending the service life of the steel grating.
[0027] In this embodiment, the rust-preventive oiling device is first assembled, then connected to an external power source for trial operation. The oiling pipe is connected to the outer wall of the connecting pipe 7. The steel grating to be oiled is then placed on top of the oiling roller brush 3 on the top of the operating table 1. The spacing of the second side brush baffle 5 is then adjusted to fit against the side wall of the steel grating for positioning. The oiling roller brush 3 is then started to rotate and move the steel grating at a uniform speed. During the movement, the nozzle 9 continuously sprays anti-corrosion oil, and the servo motor 12 drives the sector gear 11 to rotate, thereby causing the rectangular square tube 8 to swing back and forth continuously, so that the anti-corrosion oil is evenly sprayed on the top outer wall of the steel grating. Then, the electric telescopic rod 13 drives the oiling brush roller 17 to move up and down. When the oiling brush roller 17 is inserted into the grating mesh, its rotation can evenly apply the anti-corrosion oil to the edges and corners of the grating mesh, thereby improving the anti-corrosion effect.
