Description

Technical Field

[0001] The utility model relates to the technical field of metal surface cleaning, and particularly relates to an auxiliary device for metal surfaces. Background Art

[0002] Rust not only affects the appearance of metals, but also reduces their strength and corrosion resistance. Therefore, rust removal is an important part of metal processing and maintenance. Metal surface rust removal technology refers to the technology of removing metal surface oxides and rust through physical or chemical methods.

[0003] There are various rust removal methods. Among them, mechanical rust removal uses equipment such as grinders, polishers, and sandblasters for rapid rust removal, which can quickly remove oxides and rust on the metal surface, improve the rust removal efficiency, and shorten the processing time.

[0004] However, during the process of mechanical rust removal on the metal surface, the metal surface will be covered with rust soil, which needs to be manually cleaned. Some workers often use air guns connected to air pumps commonly found in factories to manually blow and clean the rust soil during actual operation. Due to the lack of highly controllable air flow guidance, this is extremely likely to cause large-scale and disorderly flying of dust, and the flying of rust soil and impurities is likely to cause harm to the eyes and respiratory system. Content of the Utility Model

[0005] In view of this, the utility model provides an auxiliary device for metal surfaces, which can guide the moving direction of rust soil and impurities and avoid large-scale and disorderly flying of rust soil.

[0006] To solve the above technical problems, the utility model provides an auxiliary device for metal surfaces, including an auxiliary frame. Both sides of the auxiliary frame are provided with chutes, and middle parts of the chutes are slidably connected with support plates. A dust removal pipe is rotatably connected to the top between the two support plates. A plurality of nozzles arranged in an array along the dust removal pipe are fixedly connected to the bottom of the dust removal pipe. A knob is fixedly connected to the middle part of one side of one of the support plates. A blower is placed on one side of the auxiliary frame, and an air outlet of the blower is communicated with one end of the dust removal pipe through an exhaust pipe. The dust removal pipe is rotatably connected with the exhaust pipe, guiding the moving direction of rust soil and impurities and avoiding large-scale flying of rust soil caused by blowing rust soil vertically or randomly and disorderly.

[0007] Both inner walls of both sides of the auxiliary frame are provided with notch openings corresponding in position. Slide bars are fixedly connected between inner walls at both ends of the notch openings, and middle parts of the slide bars are slidably connected with sliders. A plurality of guiding rods arranged in an array are fixedly connected between the two sliders, and a positioning plate is slidably connected to the middle part of the guiding rods; that is, a multi-directional adjustment function of the support plate is provided.

[0008] Both middle parts of both sides of the positioning plate are fixedly connected with pull rods; that is, the ability to manually adjust the position of the support plate is provided.

[0009] At the four corners of the top of the positioning plate, there are fixedly connected clamping blocks; this ensures the fixation of the metal plate during the cleaning process.

[0010] Between the inner walls at both ends of the sliding groove, there are rotatably connected screw rods, and the bottoms of the support plates are threadedly connected to the middle parts of the adjacent screw rods; this facilitates the adjustment of the position of the support plates.

[0011] At one end of each screw rod, there is fixedly connected a sprocket, and the two sprockets are connected by a chain drive; this enables the two screw rods to move synchronously.

[0012] At the four corners of the bottom of the auxiliary frame, there are fixedly connected mounting plates; this facilitates the fixation of the device.

[0013] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0014] 1. The spraying direction and range of the nozzle can be controlled, effectively cleaning the rust and soil on the metal surface, guiding the moving direction of the rust and impurities, avoiding the large-scale flying of rust and soil caused by blowing the rust and soil vertically or randomly and disorderly, and reducing the harm to the eyes and respiratory system.

[0024] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the technical solutions of the embodiments of the present utility model in conjunction with the appended Figures 1-4 drawings of the embodiments of the present utility model, and describe the technical solutions of the embodiments of the present utility model clearly and completely. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.

[0025] As Figures 1-4 shown: This embodiment provides an auxiliary device for a metal surface, including an auxiliary frame 100. Installation plates 106 are fixedly connected to the four corners of the bottom of the auxiliary frame 100. Installation openings are formed in the middle of the installation plates 106. Slide grooves 101 are formed at the top of both sides of the auxiliary frame 100. Support plates 102 are slidably connected to the middle of the slide grooves 101. Screw rods 103 are rotatably connected between the inner walls at both ends of the slide grooves 101. The bottoms of the support plates 102 are threadedly connected to the middle of the adjacent screw rods 103. One ends of the screw rods 103 are fixedly connected with chain wheels 104. The two chain wheels 104 are driven by a chain 105. The middle of the end of one of the screw rods 103 away from the chain wheel 104 is fixedly connected with a rocker. A dust removal pipe 201 is rotatably connected to the top between the two support plates 102. A plurality of spray heads 202 arranged in an array along the dust removal pipe 201 are fixedly connected to the bottom of the dust removal pipe 201. The middle of one side of one of the support plates 102 is fixedly connected with a knob 203. A blower 204 is placed on one side of the auxiliary frame 100. The air outlet of the blower 204 is communicated with one end of the dust removal pipe 201 through an exhaust pipe 205. The dust removal pipe 201 is rotatably connected to the exhaust pipe 205;

[0026] The auxiliary frame 100 can be fixed through the installation plates 106. When it is necessary to clean rust and soil, the staff can control the rocker to rotate, which can drive the sprockets 104 and the chain 105 to drive, so that the two screw rods 103 rotate synchronously, and then push the support plates 102 to move along the slide grooves 101 to adjust the position of the dust removal pipe 201. After the blower 204 is started, the generated air flow enters the dust removal pipe 201 through the exhaust pipe 205 and sprays out from the spray heads 202. By rotating the knob 203, the angle of the dust removal pipe 201 can be adjusted, and then the angle of the spray heads 202 can be adjusted, and then the angle of the spray heads 202 can be adjusted. In this way, the spraying direction and range of the spray heads 202 can be controlled, the rust and soil on the metal surface can be effectively cleaned, the moving direction of the rust and impurities can be guided, and the large-scale flying of the rust and soil caused by blowing the rust and soil vertically or randomly and disorderly can be avoided, reducing the harm to the eyes and respiratory system.

[0027] The positioning plate 305 is as Figure 2 、 3 shown,

[0028] Both inner walls on two sides of the auxiliary frame 100 are provided with notch openings 301 that are correspondingly positioned. A slide bar 302 is fixedly connected between the inner walls at both ends of the notch opening 301. A slider 303 is slidably connected to the middle of each slide bar 302. A plurality of guide bars 304 arranged in an array are fixedly connected between the two sliders 303. A positioning plate 305 is slidably connected to the middle of the guide bars 304. Pull rods 306 are fixedly connected to the middle parts on both sides of the positioning plate 305. Clamping blocks 307 are fixedly connected to the four corners of the top of the positioning plate 305, and the clamping blocks 307 are all L-shaped.

[0029] When cleaning the rust on the metal surface, the metal plate can be placed on the top of the positioning plate 305. The position of the metal plate can be assisted in positioning through the clamping blocks 307 to prevent the metal plate from moving during the cleaning process. Moving the positioning plate 305 through the pull rod 306 can make the positioning plate 305 move along the guide bar 304. At the same time, the existence of the slide bar 302 can make the slider 303 and the guide bar 304 move as a whole along the slide bar 302, thereby increasing the moving angle of the positioning plate 305 and improving the flexibility of the positioning plate 305. The staff can adjust the position of the positioning plate 305 according to the shape of the metal surface and the cleaning requirements, so that the staff can obtain more diverse and flexible working positions when cleaning the metal surface, improving the efficiency and convenience of cleaning the metal surface.

[0030] Working principle:

[0031] The auxiliary frame 100 is fixed to the installation surface through the mounting plate 106 to ensure stability. The staff rotates the control rocker, drives the sprocket 104 and the chain 105 to drive, makes the screw rod 103 rotate synchronously, and pushes the support plate 102 to move along the chute 101, thereby adjusting the position of the dust removal pipe 201. After the blower 204 is started, the generated air flow enters the dust removal pipe 201 through the exhaust pipe 205 and sprays out from the nozzle 202. The angle of the dust removal pipe 201 is adjusted by rotating the knob 203, and then the angle of the nozzle 202 is adjusted to control the spraying direction and range of the nozzle 202, effectively cleaning the rust and soil on the metal surface. The metal plate is placed on the top of the positioning plate 305 and is assisted in positioning through the clamping blocks 307 to prevent movement. The staff moves the positioning plate 305 through the pull rod 306 according to the shape of the metal surface and the cleaning requirements, makes the positioning plate 305 move along the guide bar 304, and at the same time, the slider 303 and the guide bar 304 move as a whole along the slide bar 302, increasing the moving angle of the positioning plate 305 and improving the flexibility.
