[0002] During the building construction process, building steel is often used to improve the bearing capacity and service life of buildings. Since building steel is easily affected by moisture, oxygen and other corrosive substances in the atmospheric environment, corrosion occurs. In order to slow down or prevent the corrosion process and extend the service life of the steel, it is necessary to spray a rust-proof coating on the surface of the building steel.

[0003] When the existing steel rust-proof coating spraying device for building construction sprays a rust-proof coating on the surface of building steel with different thicknesses, it is necessary to manually adjust the distance between the nozzle and the steel surface. Manually adjusting the position of the nozzle easily leads to inaccurate nozzle position, resulting in uneven coating sprayed on the steel surface. Therefore, improvement is needed. Content of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a steel rust-proof coating spraying device for building construction, which solves the problem that when the existing steel rust-proof coating spraying device for building construction sprays a rust-proof coating on the surface of building steel with different thicknesses and manually adjusts the distance between the nozzle and the steel surface, the nozzle position is inaccurate, resulting in uneven coating sprayed on the steel surface.

[0005] To achieve the above object, the utility model provides the following technical solution: A steel rust-proof coating spraying device for building construction, including a fixed frame. At the central position of the bottom of the fixed frame, a double-output shaft motor is fixedly installed. On both sides of the bottom of the fixed frame, support plates are symmetrically and fixedly installed. At both ends of the double-output shaft motor, rotating shafts are symmetrically provided. And the end of the rotating shaft far away from the double-output shaft motor passes through the support plate and is rotatably connected with the support plate. On both sides of the fixed frame, rectangular grooves are symmetrically provided. Inside the rectangular groove, a moving screw is rotatably installed. On the surface of the fixed frame between the two groups of moving screws, a lifting strip is provided. At the bottom of the lifting strip, a nozzle is provided. At the bottom of both sides of the fixed frame, mounting frames are symmetrically and fixedly installed. At the four corners of the bottom of the two mounting frames, bases are fixedly installed.

[0006] As a further scheme of the utility model: On both sides of the inner wall of the rectangular groove, limit sliding grooves are symmetrically provided. On the surface of both ends of the lifting strip, limit rollers are symmetrically provided, and the limit rollers correspond to the limit sliding grooves.

[0007] As a further solution of the utility model: a bevel gear is fixedly installed on one end of the rotating shaft away from the double-output shaft motor, the bottom end of the movable stud passes through the rectangular groove and extends to the bottom of the fixed frame where a bevel gear is fixedly installed, and the bevel gear at the bottom end of the movable stud is meshed with the bevel gear at one end of the rotating shaft.

[0008] As a further solution of the utility model: three groups of installation shafts 1 are fixedly installed at equal intervals inside the installation frame, and a conveying roller is rotatably installed on the surface of the installation shaft 1.

[0009] As a further solution of the utility model: mounting plates are fixedly installed on both sides of the mounting frame on one side of the fixing frame, clamping rods are symmetrically fixedly installed on the top of the mounting plates, and a top plate is fixedly installed between the top ends of the four groups of clamping rods.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The anti-rust coating spraying device for steel used in construction is provided with a double-shaft motor, a bevel gear, a movable stud and a lifting strip. According to the thickness of the steel, the double-shaft motor is controlled to rotate, and the two groups of movable studs are controlled to rotate synchronously under the meshing action of the bevel gear, so that the lifting strip is lifted and lowered on the surface of the two groups of movable studs, and the distance between the nozzle and the bottom of the fixed frame is controlled until the nozzle is located at a suitable height on the top of the steel. It is convenient to adjust the distance between the nozzle and the steel according to the thickness of the steel, and control the number of rotations of the double-shaft motor, so as to realize the precise positioning of the nozzle height.

Specific embodiments

[0018] The technical solutions of this patent will be further described in detail below in conjunction with specific embodiments.

[0019] As Figures 1 - 3 shown, the present utility model provides a technical solution: a rust-proof coating spraying device for steel in building construction, including a fixing bracket 1, a double-output shaft motor 2 is fixedly installed at the central position of the bottom of the fixing bracket 1, and support plates 4 are symmetrically and fixedly installed on both sides of the bottom of the fixing bracket 1. Rotating shafts 3 are symmetrically arranged at both ends of the double-output shaft motor 2, and the ends of the rotating shafts 3 far away from the double-output shaft motor 2 pass through the support plates 4 and are rotatably connected to the support plates 4. By providing the double-output shaft motor 2, the double-output shaft motor 2 is controlled to drive the two groups of rotating shafts 3 to rotate synchronously, so as to control the two groups of moving studs 8 to rotate synchronously, so that the lifting bar 9 can be lifted on the surfaces of the two groups of moving studs 8;

[0020] Rectangular grooves 6 are symmetrically arranged on both sides of the fixing bracket 1, limit chutes 7 are symmetrically arranged on both sides of the inner wall of the rectangular grooves 6, limit rollers 11 are symmetrically arranged on the surfaces of both ends of the lifting bar 9, and the limit rollers 11 correspond to the limit chutes 7. Due to the provision of the limit rollers 11, when the lifting bar 9 moves on the surfaces of the two groups of moving studs 8, the limit rollers 11 are driven to slide inside the corresponding limit chutes 7, ensuring that the lifting bar 9 will not deflect during the lifting movement. At the same time, the limit rollers 11 roll inside the limit chutes 7, which can reduce the friction force when the lifting bar 9 moves between the inner walls of the rectangular grooves 6.

[0021] Moving studs 8 are rotatably installed inside the rectangular grooves 6, a lifting bar 9 is arranged on the surface of the fixing bracket 1 between the two groups of moving studs 8, and a spray head 10 is arranged at the bottom of the lifting bar 9. Due to the provision of the spray head 10, when the steel passes under the spray head 10, the spray head 10 evenly sprays the rust-proof coating to cover the top of the steel;

[0022] One end of the rotating shaft 3 away from the double-output shaft motor 2 is fixedly installed with a bevel gear 5. The bottom end of the moving stud 8 passes through the rectangular groove 6 and extends to the bottom of the fixed frame 1 and is fixedly installed with a bevel gear 5. And the bevel gear 5 at the bottom end of the moving stud 8 meshes with the bevel gear 5 at one end of the rotating shaft 3. By providing the bevel gear 5, under the meshing action of the two bevel gears 5, the rotation of the output rotating shaft 3 of the double-output shaft motor 2 is transmitted to the moving stud 8, so as to control the rotation of the moving stud 8 inside the rectangular groove 6.

[0023] On both sides of the bottom of the fixed frame 1, mounting frames 12 are symmetrically and fixedly installed. At the four corners of the bottoms of the two mounting frames 12, bases 22 are fixedly installed. Inside the mounting frame 12, three mounting shafts 13 are fixedly installed at equal intervals. On the surface of the mounting shaft 13, a conveying roller 14 is rotatably installed. Due to the provision of the conveying roller 14, when the steel is placed on the top of the conveying roller 14 and pushed to move, the conveying roller 14 rolls under the bottom of the steel, thereby reducing the friction when the steel moves on the top of the mounting frame 12.

[0024] On both sides of the mounting frame 12 on one side of the fixed frame 1, mounting plates 15 are fixedly installed. On the top of the mounting plate 15, pressing rods 16 are symmetrically and fixedly installed. Between the tops of the four pressing rods 16, a top plate 17 is fixedly installed. On the surfaces of the two pressing rods 16 on the top of the mounting plate 15, pressing seats 18 are slidably installed. On the surface of the mounting plate 15 between the top plate 17 and the pressing seat 18, a pressing spring 21 is provided. By providing the pressing spring 21, under the rebounding action of the pressing spring 21, the pressing seat 18 is pressed towards the mounting plate 15, so that the pressing roller 20 is pressed downwards to approach the conveying roller 14, ensuring that the steel can be tightly fixed between the conveying roller 14 and the pressing roller 20;

[0025] Between the two pressing seats 18, three mounting shafts 19 are fixedly installed at equal intervals. On the surface of the mounting shaft 19, a pressing roller 20 is rotatably installed. Due to the provision of the pressing roller 20, when the steel is pushed to move between the conveying roller 14 and the pressing roller 20, the pressing roller 20 rolls on the top of the steel, thereby reducing the friction between the pressing seat 18 and the steel when the pressing seat 18 presses on the top of the steel.

[0026] The working principle of the present utility model is as follows:

[0027] Start the double-shaft motor 2 to rotate, control the two groups of moving studs 8 to rotate synchronously, so that the lifting strip 9 is lifted and lowered inside the fixed frame 1, and control the distance between the nozzle 10 and the bottom of the fixed frame 1 to a suitable height according to the thickness of the steel. Then stop the double-shaft motor 2 to fix the lifting strip 9 at a suitable height inside the fixed frame 1, insert the steel between the clamping roller 20 and the conveying roller 14, control the nozzle 10 to evenly spray the anti-rust coating, and at the same time push the steel through the bottom of the nozzle 10. The steel lifts the clamping roller 20, and the clamping roller 20 is pressed against the top of the steel under the rebound action of the clamping spring 21 to ensure that the unsprayed part of the steel will not arbitrarily tilt up and collide with the nozzle 10 on the top of the conveying roller 14.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
