[0040] Specifically, the working principle of this pipeline cutting device is as follows: During use, a hoisting device is utilized to move a large pipeline onto the first support frame 150. According to the cutting height, the first motor 137 operates. The rotation of the output shaft of the first motor 137 drives the rotation of the third gear transmission member 136. The rotation of the third gear transmission member 136 drives the rotation of the second connecting rod 135. The rotation of the second connecting rod 135 drives the rotation of the first gear transmission member 132. The rotation of the first gear transmission member 132 drives the rotation of the first connecting rod 131. The rotation of the first connecting rod 131 drives the rotation of the second gear transmission member 133. The rotation of the second gear transmission member 133 drives the rotation of the lead screw 134. Under the combined action of the first gear transmission member 132, the second gear transmission member 133, and the third gear transmission member 136, the second frame 120 moves up and down, that is, the height of the large pipeline is adjusted. After adjustment, when it is necessary to move the large pipeline, the second motor 144 operates. The rotation of the output shaft of the second motor 144 drives the rotation of one of the sprockets 142. The rotation of the sprocket 142 drives the rotation of the chain 141, realizing the movement of the push block 143. Under the combined action of the push block 143 and the first support frame 150, the large pipeline moves forward. When the large pipeline moves to the designated position, according to the cutting angle of the large pipeline, the third motor 183 operates. The rotation of the output shaft of the third motor 183 drives the rotation of the first gear 181 and the second gear 182. The rotation of the first gear 181 drives the rotation of the circular plate 170, realizing the adjustment of the angle of the cutting tool of the cutting machine 1904. After adjustment, the fourth motor 1931, the hydraulic cylinder 1902, and the cutting machine 1904 operate simultaneously. The retraction of the piston rod of the hydraulic cylinder 1902 drives the cutting tool of the cutting machine 1904 to move downward. The cutting machine 1904 operates to make the cutting tool rotate. The fourth motor 1931 operates to drive the rotation of the first wire reel 1932. One of the two first wire reels 1932 winds up the steel wire rope 1933, and the other first wire reel 1932 pays out the steel wire rope 1933. Under the combined action of the fourth motor 1931, the hydraulic cylinder 1902, and the cutting machine 1904, the large pipeline is cut as required. This pipeline cutting device only needs to adjust the orientation of the cutting machine 1904 to cut the large pipeline as required, with high precision, high efficiency, and low requirements for the operator's proficiency, bringing a better user experience to the user.

[0041] It should be noted that the specific model specifications of the first motor 137, the second motor 144, the third motor 183, the hydraulic cylinder 1902, the cutting machine 1904, and the fourth motor 1931 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail here.

[0042] The power supply and its principle of the first motor 137, the second motor 144, the third motor 183, the hydraulic cylinder 1902, the cutting machine 1904 and the fourth motor 1931 are clear to those skilled in the art and will not be described in detail herein.
