DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Reference Figs. 1-3The utility model provides a kind of surface rust-proof device for steel truss production usage, including workbench 1 and cleaning component, workbench 1 is the basic platform of entire device, for carrying steel truss and other components, provide support and installation foundation for various operations, cleaning component is installed with the outside of workbench 1, the bottom of workbench 1 is fixedly connected with installation cylinder 2, inside accommodate piston 3 etc.

[0023] Specifically, after the steel truss is clamped and positioned, the motor 9 is started, the motor 9 drives the reciprocating screw rod 8 to rotate, at the same time, the cam 22 will also rotate with the operation of the motor, and the protruding part of the cam 22 will periodically contact and push the sliding rod 4 to move during the rotation process. When the protruding part of the cam 22 leaves the sliding rod 4, the piston 3 will quickly reset under the elastic force of the spring 5, so that the piston 3 realizes the reciprocating movement in the installation cylinder 2. When the piston 3 moves outward, it will inhale from the connecting pipe 7, and when the piston 3 moves inward, it will deliver the inhaled gas to the spray head through the conduit 6. At this time, the spray head will perform a blowing operation, and the blown gas will be used to preliminarily clean the dust on the surface of the steel truss, and the floating dust and other impurities on the surface will be blown away. At the same time, under the rotating action of the reciprocating screw rod 8, the paint spraying frame 12 will drive the brush plate 13 to move reciprocally along the guide rod 10. The brush of the brush plate 13 will fully contact the surface of the steel truss during the movement, further cleaning the dust on the surface of the steel truss, and cleaning the stubborn dust and impurities, so as to prepare for the paint spraying process. When it is necessary to spray paint on the steel truss, the connecting pipe 7 is connected to the external protective paint storage pipeline. At this time, the original blowing mode can be changed to the paint spraying mode. Under the reciprocating movement of the piston 3, the protective paint will be continuously extracted and delivered to the spray head through the conduit 6, and then uniformly sprayed on the surface of the steel truss. In this way, the overall protection and decoration of the steel truss can be realized, the service life and appearance quality of the steel truss are improved, and the working efficiency and operation accuracy are improved through the coordinated work of various components.

[0024] Referring to Figs. 1-3 The positioning assembly includes a mounting box 16 for providing installation space and protection for the internal rotating column 17, cylindrical gear 18 and other components. The mounting box 16 is fixedly connected to the outside of the workbench 1. Two rotating columns 17 are rotatably connected in the inside of the mounting box 16. The outside of the rotating column 17 is fixedly connected with a cylindrical gear 18. The top of the rotating column 17 is fixedly connected with an arc-shaped rod 19. A slot hole 20 is formed in the inside of the mounting box 16. A rack 21 is slidably connected to the inside of the slot hole 20. The cylindrical gear 18 is engaged with the outside of the rack 21. The bottom of the arc-shaped rod 19 is provided with an anti-skid column. The anti-skid column at the bottom of the arc-shaped rod 19 is used to contact with the steel truss to clamp and fix the steel truss from the side or other directions.

[0025] Specifically, before the rust-proof treatment, the steel truss is carefully placed on the top of the workbench 1, the electric push rod 14 is started, the electric push rod 14 starts to work and drives the push plate 15 to push the steel truss to move, when one end of the steel truss contacts the rack 21, the rack 21 slides smoothly along the inside of the slot hole 20 due to the continuous pushing force of the push plate 15, the sliding of the rack 21 drives the two cylindrical gears 18 engaged with the rack 21 to rotate, with the rotation of the cylindrical gears 18, the two arc-shaped rods 19 gradually move towards the middle, in this process, the arc-shaped rods 19 not only can tightly clamp the two sides outside the steel truss, ensure that the steel truss does not deviate in the subsequent operation process, but also can correct the deviation of the steel truss during clamping, the clamping and stable operation of the steel truss from four directions can effectively ensure that the steel truss is in a stable and correct position on the workbench, which provides a good foundation condition for the subsequent dust removal and paint spraying processes.

[0026] Working principle: first, the steel truss is directly placed on the top of the workbench 1, the electric push rod 14 is started to drive the push plate 15 to push the steel truss to move, when one end of the steel truss contacts the rack 21, the rack 21 slides towards the inside of the slot hole 20, the rack 21 also drives the two cylindrical gears 18 to rotate, so that the two arc-shaped rods 19 gradually move towards the middle to clamp the two sides outside the steel truss, and the arc-shaped rods 19 can also correct the deviation of the steel truss during clamping, so that the steel truss can be clamped and stabilized from four directions.

[0027] After the steel truss is clamped and positioned, the motor 9 is started to drive the reciprocating screw rod 8 to rotate, the cam 22 rotates at the same time and pushes the sliding rod 4 to drive the piston 3 to move, under the elastic force of the spring 5, the piston 3 quickly resets, realizing the reciprocating movement of the piston 3, which can inhale air from the connecting pipe 7 and then deliver the air to the nozzle for blowing, at the same time, the paint spraying frame 12 moves along the guide rod 10 to drive the brush plate 13 to reciprocate, and the surface of the steel truss is treated for dust removal, the connecting pipe 7 is connected to the external pipeline for extracting protective paint, and the blowing mode can be changed to the paint spraying mode.

[0028] Finally, it should be pointed out that: the above only describes the preferred embodiments of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
