Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-2 In this embodiment of the utility model, a pipe welding robot includes a base 1, a welding robot body 2, and an outer frame 3. The welding robot body 2, model SP235, is mounted on the base 1. The outer frame 3 is mounted on one side of the base 1. A slag guide hopper 4 is mounted inside the outer frame 3. A slag collection drawer 5 is mounted directly below the slag guide hopper 4 inside the outer frame 3. Four wheels 6 are mounted on the bottom of the slag collection drawer 5. Two rollers 7 are mounted on the outer frame 3. A latch 16 is mounted on the drawer door of the slag collection drawer 5. The latch 16 engages with a hook 15 mounted on the outer frame 3. The engagement of the latch 16 and the hook 15 can fix the slag collection drawer 5 to the outer frame 3, preventing the slag collection drawer 5 from sliding out from the bottom of the outer frame 3 during use. A handle 14 is mounted on the drawer door of the slag collection drawer 5. The handle 14 facilitates pulling the slag collection drawer 5 outward.
[0021] Please see Figure 1 and Figure 3 A baffle 8 is installed on the outer frame 3 to prevent welding slag from splashing onto one side of the baffle 8. A fume hood 9 is installed on the baffle 8, and a fume pipe 10 is connected to the fume hood 9. The other end of the fume pipe 10 is connected to a fume treatment box 11 located on one side of the outer frame 3. The fume treatment box 11 is equipped with a coarse filter plate 17, a fine filter plate 18, and an activated carbon plate 19. A fan 13 is installed on the wall of the fume treatment box 11. The coarse filter plate 17, the fine filter plate 18, the activated carbon plate 19, and the fan 13 are arranged sequentially from front to back along the direction of flue gas flow. The carbon plate 19 is inserted into the flue gas treatment box 11 from above. The bottom surface of the flue gas treatment box 11 is equipped with a slot 20 that matches the coarse filter plate 17, the fine filter plate 18 and the activated carbon plate 19. The slot 20 serves as a limit. The top of the coarse filter plate 17, the fine filter plate 18 and the activated carbon plate 19 are all equipped with sealing covers. The sealing covers are pressed on the flue gas treatment box 11 and are used to seal the insertion port at the top of the flue gas treatment box 11. A pull ring 21 is installed on the sealing cover to facilitate personnel to pull out each filter plate or activated carbon plate 19 for surface cleaning or replacement.
[0022] A cleaning door panel 12 is installed on the front end of the flue gas treatment box 11. The upper part of the cleaning door panel 12 is hinged to the flue gas treatment box 11, and the lower part of the cleaning door panel 12 is fixed to the flue gas treatment box 11 by screws. There are two cleaning door panels 12, which correspond to the cavity between the coarse filter plate 17 and the flue gas treatment box 11 and the cavity between the coarse filter plate 17 and the fine filter plate 18, respectively. This facilitates the regular cleaning of the smoke and dust intercepted by the coarse filter plate 17 and the fine filter plate 18 in the flue gas treatment box 11.
[0023] It should be noted that this application must be used in conjunction with a circular pipe rotation fixture. The circular pipe rotation fixture clamps the non-welded ends of the two pipe sections and drives the pipe to rotate through its own drive device. This makes it easier for the welding robot body 2 to perform circumferential welding on the circular pipe. The circular pipe rotation fixture model is QW-XZ005, which is an existing mature product and will not be described in detail here.
[0024] The working principle of this utility model is as follows:
[0025] During use, the welding robot body 2 will cause welding slag to fall into the outer frame 3 during the welding process of the pipe, and then be guided into the slag collection drawer 5 through the slag guide hopper 4. After the welding is completed, the operator can directly pull out the slag collection drawer 5 by holding the handle 14 and being driven by the walking wheels 6 to clean the welding slag in the slag collection drawer 5. The fumes raised during the welding process will be drawn into the fume hood 9 and enter the fume hood 10 by the fan 13, and then enter the flue gas treatment box 11 through the fume hood 10. The particulate impurities in the flue gas will be filtered when passing through the coarse filter plate 17 and the fine filter plate 18, and finally the harmful gases in the flue gas will be adsorbed by the activated carbon plate 19 before being discharged.
[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
