[0014] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 and attached Figure 2 As shown, a special turning device for welding a shovel loader bucket comprises a U-shaped bracket 1, wherein a rotating shaft 2 is connected to a bearing on the upper middle side of the U-shaped bracket 1, and the front end of the rotating shaft 2 passes through the front side of the U-shaped bracket 1; a worm gear reduction motor 3 is fixedly connected to the upper middle side of the front part of the U-shaped bracket 1, and the hollow output shaft of the worm gear reduction motor 3 is key-connected to the front end of the rotating shaft 2; a connecting block 4 is fixedly connected to the upper middle side of the rotating shaft 2, and the connecting block 4 is located on the inner side of the U-shaped bracket 1, wherein a V-shaped supporting plate 5 is fixedly connected to the upper middle side of the connecting block 4; ear plates 6 are fixedly connected to the front and rear sides of the inner bottom of the V-shaped supporting plate 5, respectively, and plug holes are respectively provided on the upper middle side of the ear plates 6, wherein a plug rod 7 is internally inserted between the plug holes; through holes are longitudinally provided on the front and rear sides of the plug rod 7, and cotter pins 8 are installed inside the through holes, wherein the cotter pins 8 are respectively located on the outer sides of the ear plates 6.

[0015] One of the special flipping devices for welding a shovel loader bucket also includes a protective support assembly 9, and the protective support assembly 9 is respectively fixedly connected to the front and rear sides of the inner bottom of the U-shaped bracket 1, which is conducive to achieving the protective effect and can effectively avoid the problem of sudden rotation of the V-shaped support plate 5, thereby effectively improving the safety of the device.

[0016] Among them, the protective support assembly 9 includes an arc-shaped fixed tube 91, and a protective support rod 92 is slidably arranged inside the arc-shaped fixed tube 91; the left and right openings on the upper side of the arc-shaped fixed tube 91 are respectively threadedly connected with fastening bolts 93, and the arc-shaped fixed tube 91 is fastened and connected to the protective support rod 92 by the fastening bolts 93.

[0017] In this embodiment, specifically, the middle and lower sides of the arc-shaped fixing tube 91 are fixedly connected to the front and rear sides of the middle part of the inner bottom of the U-shaped bracket 1 respectively.

[0018] In this embodiment, specifically, one end of the protective support rod 92 is respectively against one side of the V-shaped support plate 5 .

[0019] In this embodiment, specifically, the arc-shaped fixed tube 91 is an arc-shaped alloy steel tube.

[0020] In this embodiment, specifically, the protective support rod 92 is an alloy steel rod adapted to the interior of the arc-shaped fixed tube 91 .

[0021] In this embodiment, specifically, the worm gear reduction motor 3 is electrically connected to an external control panel.

[0022] In this embodiment, combined with the Figure 3 and attached Figure 2 As shown, when using the device, the U-shaped bracket 1 needs to be fixed on the external ground first; when installing the bucket, the operator can first place the bucket on the inner side of the V-shaped support plate 5, and insert the insertion rod 7 into the insertion hole and the installation hole of the bucket to fix the bucket on the inner side of the V-shaped support plate 5, and then insert the cotter pin 8 into the through hole, thereby avoiding the problem of the insertion rod 7 moving out of the insertion hole or the installation hole of the bucket by itself, and then completing the installation of the bucket; when flipping the bucket, the operator can directly control the worm gear reduction motor 3 to start through the external control panel, so that the worm gear reduction motor 3 drives the rotating shaft 2 to rotate slowly, and the rotating shaft 2 will drive the V-shaped support plate 5 to rotate through the connecting block 4, and the bucket is flipped at this time. Because the right side of the bucket is slightly higher than the bottom of the U-shaped bracket 1 after the bucket is flipped, when welding the bucket, the operator does not need to use the heightening structure to weld the bucket, so as to achieve the effect of installing the bucket at a low height, which can effectively avoid the problem that the operator needs to use the heightening structure to process the bucket.

[0023] When the bucket is turned over, the operator can loosen the fastening bolts 93 with an external wrench to allow the protective support rod 92 to slide inside the arc-shaped fixed tube 91. The operator can then observe the deviation of the center of gravity of the device. When the center of gravity shifts to the right, the operator can lean the right end of the protective support rod 92 against the right side of the V-shaped support plate 5. When the center of gravity shifts to the left, the operator can lean the left end of the protective support rod 92 against the left side of the V-shaped support plate 5. Finally, the operator can tighten the fastening bolts 93 with a wrench, thereby preventing the V-shaped support plate 5 from suddenly and damagingly rotating through the protective support rod 92, thereby effectively ensuring production safety and greatly improving the safety of the device.

[0024] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
