[0002] In project construction, pipe welding is the most common method of pipe connection. At this stage, the country vigorously promotes prefabricated construction, and pipe prefabrication production is gradually increasing.

[0003] When welding pipes, welders generally use movable brackets to support the pipe clamps and motors. However, when the pipe clamps and motors are in a parallel state for flat fillet welding, it is easy to produce defects such as undercuts and uneven weld feet. In order to adjust the fillet weld to a boat-shaped weld, it is necessary to adjust the welding angle, that is, to adjust the inclination angle of the pipe clamps and motors. However, the existing brackets are generally fixed and inconvenient to adjust. Therefore, we proposed a chuck-type pipe rotation device to assist pipe welding. Utility Model Content

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] The embodiment of the utility model discloses a chuck-type pipeline rotating device for assisting pipeline welding.

[0024] According to the attached Figure 1-4 As shown, including:

[0025] The support unit mainly includes a support plate 1, a first support rod 101 and a second support rod 102 are installed at the bottom of the support plate 1, the bottom of the first support rod 101 is connected to a limited seat 103, the bottom of the second support rod 102 is rotatably connected to a fixed seat 104, and a limited lifting assembly is installed between the limited seat 103 and the first support rod 101, and the limited lifting assembly is used to drive the bottom end of the first support rod 101 to move in an arc;

[0026] The rotating unit mainly includes a driving motor 2 and a pipe chuck 203. The driving motor 2 and the pipe chuck 203 are both installed on the top of the support plate 1. The driving motor 2 is transmission-connected to the pipe chuck 203, and the pipe chuck 203 is used to fix the pipe.

[0027] By setting a limit lifting assembly, the limit lifting assembly can drive the bottom end of the first support rod 101 to move in an arc, thereby making the support plate 1, the first support rod 101 and the second support rod 102 rotate relative to the fixed seat 104 with the bottom end of the second support rod 102 as the axis, and the driving motor 2 on the top of the support plate 1 and the pipe clamp 203 can be adjusted. The pipe clamp 203 is used to fix the pipe, so that the pipe can be adjusted accordingly, and when welding, it is convenient to adjust the pipe to a suitable angle, and adjust the fillet weld to a boat-shaped weld, thereby overcoming the defects of undercut and uneven weld feet that are easy to produce when flat fillet welding.

[0028] Furthermore, a base 105 is installed at the bottom of the limiting seat 103 and the fixing seat 104 .

[0029] Furthermore, a reducer 201 is installed at the end of the driving motor 2 , and a coupling 202 is installed between the reducer 201 and the pipe chuck 203 .

[0030] Specifically disclosed, the position-limiting lifting assembly includes:

[0031] The limiting groove 3 is formed on the outer wall of the limiting seat 103 and is connected to the interior of the limiting seat 103. The bottom of the first support rod 101 is inserted into the interior of the limiting seat 103, and the limiting rod 301 is movably inserted into the interior of the bottom of the first support rod 101. The end of the limiting rod 301 extends outward through the limiting groove 3;

[0032] The moving block 4 is slidably disposed inside the limiting seat 103 , and the moving block 4 is tightly against the bottom of the first support rod 101 .

[0033] Because the moving block 4 is tightly against the bottom of the first support rod 101, when the moving block 4 moves upward, it can push the bottom of the first support rod 101 to move upward, and the bottom of the first support rod 101 can only move in an arc along the limiting groove 3 under the action of the limiting rod 301. When the moving block 4 moves downward, the first support rod 101 moves in an arc along the limiting groove 3 under the weight of the structure above it, so that the bottom end of the first support rod 101 is always against the moving block 4.

[0034] Furthermore, the end of the limiting rod 301 at the outside is threadedly connected to a positioning ring 302 , and the positioning ring 302 fits with the outside of the limiting seat 103 .

[0035] The positioning ring 302 is provided so as to fit in with the exterior of the limiting seat 103 , thereby positioning the limiting rod 301 .

[0036] Furthermore, a screw rod 401 is fixedly installed inside the limiting seat 103 , and a threaded sleeve 402 is threadedly connected to the outer peripheral wall of the screw rod 401 , and the top end of the threaded sleeve 402 is rotatably connected to the moving block 4 .

[0037] When the threaded sleeve 402 is rotated, the outer wall of the screw rod 401 is threadedly connected to the threaded sleeve 402, so that the threaded sleeve 402 moves vertically relative to the screw rod 401, and the top end of the threaded sleeve 402 is rotationally connected to the moving block 4, so the top end of the threaded sleeve 402 can push the moving block 4 to move vertically inside the limit seat 103.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
