Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a pipe trench processing device. Background Technology

[0002] A pipeline grooving device, with publication number CN 220277984 U, is described. In use, the operator first inserts the right side of the pipe to be grooved into the first grooving wheel. Then, the operator controls the second motor to operate via a control switch group. The output shaft rotates, driving the lead screw to rotate, thus inserting the second grooving wheel on the sliding plate into the left side of the pipe, securing both. Next, the operator rotates the hexagonal head with a wrench, causing the screw to rotate and move the adjusting pressure wheel to be parallel to the second grooving wheel. Then, the operator controls the third motor to operate via a control switch group. The output shaft rotates, driving the bidirectional lead screw to rotate, causing the connecting rods on both rotating frames to retract inwards. This moves the sliding plate on the rotating seat downwards, bringing the pressure wheel and adjusting pressure wheel close to the surface of the pipe. Finally, the operator controls the third motor to operate via a control switch group. The output shaft rotates, driving the first grooving wheel to rotate, causing the pipe to rotate under the pressure of the pressure wheel and adjusting pressure wheel, completing the grooving process. However, when the above-mentioned device provides rotational support for the pipeline, it only uses a sliding plate to push and fix the end. During the rotation process, the pipeline may fail to rotate. In addition, the position of the adjusting pressure roller needs to be readjusted according to the length of the pipeline, which causes inconvenience to use. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-7 As shown, a pipe grooving device includes a support frame 1, on which a rotating support mechanism for rotating and supporting a pipe is provided, and a grooving mechanism for simultaneously grooving both ends of the pipe.

[0028] In this embodiment: the rotating support mechanism includes a support base 21 disposed opposite to each other, a fixing component for clamping and limiting the pipe is disposed on the support base 21, and a rotating component for rotating the fixing component is disposed between the fixing components.

[0029] The fixing assembly includes a mounting ring 22 rotatably mounted on a support base 21. Three grooves 221 are evenly distributed on the outer side of the mounting ring 22. A rotating ring 23 is disposed inside the mounting ring 22. A clamping rod 24 is installed between the rotating ring 23 and the grooves 221. A limiting disc 25 is installed on the outermost side of the rotating ring 23 to limit the clamping rod 24. A worm gear ring 26 is installed on the side of the rotating ring 23 away from the limiting disc 25. A worm 27 that meshes with the worm gear ring 26 is rotatably mounted on the mounting ring 22. The rotating ring 23 is rotatably connected to the mounting ring 22. The clamping rod 24 and the grooves 221 are... 21. Sliding connection; Limit pins are provided on both sides of the clamping rod 24 away from the slide groove 221. The limit pins are rotatably connected to the rotating ring 23 and the limit plate 25. The limit plate 25 is fixedly connected to the rotating ring 23 by bolts. After the pipe is placed between the clamping rods 24, the worm 27 is rotated so that the worm 27 meshes with the worm wheel ring 26 and rotates, driving the rotating ring 23 and the limit plate 25 to rotate. During the rotation, the angle of the clamping rod 24 is adjusted under the limit of the slide groove 221 so that the clamping rod 24 clamps and fixes the pipe, thereby supporting and fixing the pipe.

[0030] The rotating assembly includes a connecting sleeve 28 fixed between rotating rings 23. A gear ring 29 is fixed on the outer diameter of the connecting sleeve 28. A drive gear 210 meshes with the lower side of the gear ring 29. One end of the drive gear 210 is connected to a reduction motor 211. The reduction motor 211 drives the drive gear 210 to mesh with the gear ring 29 and rotate, causing the connecting sleeve 28 to rotate, which in turn drives the fixed assembly and the pipe to rotate as a whole.

[0031] In this embodiment: the grooving mechanism includes a guide post 31 and left and right spiral screws 32 arranged parallel to each other on the upper side of the rotating support mechanism. One end of the left and right spiral screws 32 is connected to a servo motor 33. Adjusting seats 34 are installed opposite to each other on the guide post 31 and the left and right spiral screws 32. A first hydraulic cylinder 35 and a second hydraulic cylinder 36 are installed sequentially from the outside to the inside on the adjusting seat 34. A grooved wheel 37 is fixed to the lower end of the first hydraulic cylinder 35, and a pressure wheel 38 is fixed to the lower end of the second hydraulic cylinder 36. The left and right spiral screws 32 are rotatably connected to the support frame 1, the adjusting seat 34 is threadedly connected to the left and right spiral screws 32, and the adjusting seat 34 is slidably connected to the guide post 31. The top of the support frame 1 has a through groove through which the first hydraulic cylinder 35 and the second hydraulic cylinder 36 pass. After rotating the support mechanism, the servo motor 33 drives the left and right helical screws 32 to rotate, causing the left and right helical screws 32 to push the adjusting seat 34 to move towards the middle position under the limit of the guide post 31. At the same time, the first hydraulic cylinder 35 extends and pushes the grooved wheel 37 down to align and limit the two ends of the pipe, and then clamps and fixes the pipe. The second hydraulic cylinder 36 extends and pushes the grooved wheel 37 down to contact the pipe for grooving. The first hydraulic cylinder 35 and the second hydraulic cylinder 36 are connected to a hydraulic system (not shown in the figure) to control the extension and retraction of the first hydraulic cylinder 35 and the second hydraulic cylinder 36. Those skilled in the art know how to set up the control when the above actions are to be completed. This is prior art and will not be described in detail here.

[0032] The working principle and usage process of this utility model are as follows: The pipe passes through the limiting plate 25, the rotating ring 23, and the connecting sleeve 28. The clamping rod 24 supports the pipe. The servo motor 33 drives the left and right helical screws 32 to rotate, causing the left and right helical screws 32 to push the adjusting seat 34 to move towards the middle position under the limit of the guide post 31. At the same time, the first hydraulic cylinder 35 extends and pushes the grooved wheel 37 down to align and limit the two ends of the pipe. Then, the worm 27 is rotated, so that the worm 27 meshes with the worm wheel ring 26 and rotates, causing the rotating ring 23 and the limiting plate 25 to rotate. During the rotation, the clamping rod 24 is adjusted in angle under the limit of the slide groove 221, so that the clamping rod 24 clamps and fixes the pipe. Then, the reduction motor 211 drives the drive gear 210 to mesh with the gear ring 29 and rotate, causing the connecting sleeve 28 to rotate, which in turn drives the fixed pipe to rotate. The second hydraulic cylinder 36 extends and pushes the grooved wheel 37 down to contact the pipe for grooving processing.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
