DETAILED DESCRIPTION

[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Combined with reference Figure 1-Figure 4 The utility model provides a spraying device for anti-corrosion of steel components, including a spraying baffle 1, a mounting hole is provided on the spraying baffle 1, and the mounting hole can cooperate with bolts to install the spraying baffle 1 in a designated spraying area, and a circulating transmission structure 2 is provided on the spraying baffle 1, and a plurality of chain fixing blocks 3 are provided on the circulating transmission structure 2, and a spraying rotary rod 4 is rotatably connected to the chain fixing block 3, and a plurality of tooth grooves 5 are annularly provided on the spraying rotary rod 4, and a hanging ear 6 for hanging steel components is fixedly connected to the bottom end of the spraying rotary rod 4, and the hanging ear 6 can cooperate with the steel component with a hole for hooking, so as to realize the mobile anti-corrosion spraying of the steel component, and the hanging ear 6 can meet the requirements of taking and placing the steel component. The spraying baffle 1 is provided with a transmission member for engaging the tooth groove 5, and a hanging plate 8 is fixedly mounted on the spraying baffle 1. A telescopic device 9 is fixedly connected to the side of the hanging plate 8. The telescopic device 9 can adopt telescopic equipment such as an electric telescopic rod. A mounting plate 10 is provided at the output end of the telescopic device 9. A pair of spray frames 11 facing the spraying baffle 1 are fixedly connected to the mounting plate 10. When the spray frames 11 face the spraying baffle 1 to perform anti-corrosion spraying on the steel structure, the spraying baffle 1 can prevent the spray material from scattering.

[0023] The circulating transmission structure 2 includes a pair of sprockets 21 rotatably connected to the spray baffle 1, a transmission chain 22 transmission-connected to the pair of sprockets 21, and a rotating motor 23 fixedly connected to the spray baffle 1. The output end of the rotating motor 23 is fixedly connected to one of the sprockets 21. A tensioning gear can be provided on the spray baffle 1 of the present application to engage the transmission chain 22, thereby improving the transmission stability of the transmission chain 22.

[0024] The chain fixing block 3 is fixedly connected to the chain plate of the transmission chain 22 .

[0025] Specifically, by controlling the step-by-step driving of the rotary motor 23 , the rotation of the sprocket 21 can make the transmission chain 22 move in a circular motion, so that the plurality of chain fixing blocks 3 can move in a circular motion on the path of the transmission chain 22 .

[0026] In the present application, a suitable spacing should be reserved between the chain fixing block 3 arranged on the transmission chain 22 and the spray baffle 1 to ensure that the steel component on the hanging ear 6 can rotate within the effective range.

[0027] The transmission part includes a bracket 7 fixedly connected to the spray baffle 1 and a tooth block array 71 fixedly connected to the bracket 7. The tooth block array 71 is meshed with the tooth groove 5. In the present application, the tooth block array 71 is composed of a plurality of tooth blocks arranged in sequence. The meshing with the tooth groove 5 can make the spray rotary rod 4 rotate at least three times, thereby ensuring that the suspended and rotating steel components can be evenly and fully sprayed with anti-corrosion.

[0028] It is worth noting that, since the rotary motor 23 is driven in a step-by-step manner, the travel distance of each step of the transmission chain 22 should be greater than the length of the tooth block array 71, so as to ensure that the steel component can be effectively sprayed during the step-by-step movement.

[0029] A cantilever 12 is fixedly connected to the spraying baffle 1 , and one end of the cantilever 12 facing away from the spraying baffle 1 is fixedly connected to the hanging plate 8 .

[0030] A slide 13 is fixedly connected to the mounting plate 10, and the slide 13 is slidably connected to the hanging plate 8. The sliding connection of the slide 13 to the hanging plate 8 can give the mounting plate 10 stability in linear movement, thereby ensuring the stability of the spray rack 11 during mobile spraying.

[0031] A pair of spray racks 11 are fixedly connected with a three-way material pipe 14, and valves are arranged on the two-way pipelines of the three-way material pipe 14 facing the pair of spray racks 11. One end of the three-way material pipe 14 facing away from the pair of spray racks 11 is externally connected to an anti-corrosion material pumping device. The setting of a pair of valves can independently control the spray rack 11 located at the top to realize the on and off of spraying or the synchronous spraying of a pair of spray racks 11. When shorter steel components are sprayed, the spray rack 11 located at the top can be used. When longer steel components are sprayed, a pair of spray racks 11 can be used at the same time. This can effectively adapt to the spraying of steel components of different lengths, thereby reducing the waste of spraying materials.

[0032] Specifically, after the steel component is manually hung on the hanging ear 6, the transmission chain 22 drives the steel component to move in a straight line below the transmission chain 22. When the tooth block row 71 engages the tooth groove 5, the spraying rotary rod 4 can rotate at least three circles on the chain fixing block 3. At this time, the telescopic device 9 can drive the spraying frame 11 on the mounting plate 10 to move along with the moving steel component, so that the spraying frame 11 can spray the rotating steel component with anti-corrosion material to ensure the uniformity of the spraying. Until the next steel component moves to the transmission part position, the telescopic device 9 drives the spraying frame 11 to restore its position, so as to continue the anti-corrosion spraying operation on the steel component on one side.
