[0029] As Figures 1 to 5 shown, the present utility model provides an orbital engineering steel rail welding device, including an orbital automatic welding machine 1. The orbital automatic welding machine 1 is an existing public technology and will not be elaborated here. A displacement component 2 is installed on the orbital automatic welding machine 1. The displacement component 2 is connected to a movable baffle 3. An inhalation component 4 is installed on the movable baffle 3. During welding, the movable baffle 3 is moved to the position where the sparks splash, so as to block the sparks from splashing outward and avoid the sparks from splashing onto the surrounding staff, thereby protecting the staff;

[0030] The inhalation component 4 includes an air pump 401. The inlet of the air pump 401 is connected to a water tank 402 through a pipeline. The water tank 402 is connected to a U-shaped pipe 403 through a pipeline. The U-shaped pipe 403 is fixed on the outer side of the movable baffle 3. The U-shaped pipe 403 is connected to an air suction port 404. The air suction port 404 is installed on the inner side of the movable baffle 3. During welding, the inhalation component 4 sucks away the generated smoke and some sparks by sucking air, and uses water for cooling and adsorption to reduce the impact of the smoke on the surrounding working environment.

[0031] Specifically, the displacement component 2 includes a driving motor 201. The output end of the driving motor 201 is connected to a lead screw 202. A positioning slide bar 203 is arranged below the lead screw 202. A movable sliding sleeve 204 is connected between the lead screw 202 and the positioning slide bar 203. The movable sliding sleeve 204 is fixedly connected to the movable baffle 3.

[0032] Further, two corresponding fixed plates 5 are fixed on the orbital automatic welding machine 1. One end of the lead screw 202 is connected to the fixed plate 5 through a bearing, and the other end penetrates through the fixed plate 5 and is connected to the driving motor 201. Both ends of the positioning slide bar 203 are fixedly connected to the fixed plate 5.

[0033] Still further, a threaded hole 6 is provided at a position on the movable sliding sleeve 204 corresponding to the lead screw 202. The threaded hole 6 is threadedly connected to the lead screw 202.

[0034] It should be noted that a positioning slide hole 7 is provided at a position on the movable sliding sleeve 204 corresponding to the positioning slide bar 203. The positioning slide bar 203 is arranged in the positioning slide hole 7.

[0035] It should be noted that the top position of the movable baffle 3 is bent inward to form a bent section 8.

[0036] It is worth introducing that cooling water 9 is provided in the water tank 402. A corresponding filter screen 10 and a partition 11 are provided above the cooling water 9. A liquid level window 12 is installed on the front side of the water tank 402.

[0038] Working principle and process: Place the track automatic welding machine 1 on the steel rail to be welded through specific mechanical equipment. Subsequently, the track automatic welding machine 1 operates for welding work. At the same time, start the drive motor 201 of the displacement component 2, and then the lead screw 202 rotates. Under the limitation of the thread and the positioning slide bar 203, the moving slide sleeve 204 moves, which can drive the moving baffle 3 to move to the position where the sparks splash, so as to block the outward splash of the sparks and prevent the sparks from splashing onto the surrounding staff, ensuring the personal safety of the staff. Start the air pump 401 of the suction component 4. The smoke and some sparks generated by the air mixture welding enter through the suction port 404, and are introduced into the water tank 402 after passing through the U-shaped pipe 403. The sparks and some smoke particles are intercepted by the filter screen 10, and the sparks fall into the cooling water 9 for rapid cooling. Then, blocked by the partition plate 11, they pass through the water surface, enabling the cooling water 9 to adsorb the smoke particles, and finally are discharged by the air pump 401 to reduce the impact of the smoke on the surrounding working environment.
