[0020] Reference Figure 1-4 A heavy-duty pipe cutting and lifting mechanism comprises a fixed frame 1, which is arranged in an "L" shape. A plurality of lifting plates 2 are slidably connected to the side wall of the fixed frame 1, and the plurality of lifting plates 2 are fixedly connected to each other. A pushing cylinder 3 is fixedly arranged at the top of the horizontal end of the fixed frame 1, and a pushing rod 4 is fixedly connected to the output end of the pushing cylinder 3. The other end of the pushing rod 4 is arranged in contact with the bottom wall of the lifting plate 2.

An adjusting groove 7 corresponding to the adjusting block 6 is opened at the top of the lifting plate 2, and a clamping structure is arranged on the adjusting groove 7. The pipe is placed on the lifting plate 2, and the pushing cylinder 3 is started. The pushing cylinder 3 pushes the pushing rod 4 to move, so that the lifting plate 2 and the pipe move upward together, thereby facilitating the cutting of the pipe.

[0021] An adjusting screw 8 is rotatably connected to the side wall of the adjusting block 6 away from the vertical end of the fixing frame 1. The adjusting screw 8 penetrates the inner wall of the adjusting slot 7 and extends to the outer side of the lifting plate 2. A fixed gear 9 is sleeved on the lifting plate 2, and the fixed gear 9 is rotatably connected to the side wall of the corresponding lifting plate 2 through a rotating rod. A plurality of fixed racks 10 are fixedly connected to the top of the horizontal end of the fixing frame 1, each fixed rack 10 corresponds to a fixed gear 9, and the fixed rack 10 is meshed with the fixed gear 9. One end of the adjusting screw 8 away from the adjusting block 6 is fixedly connected to a limited block, and a limit block is provided at the connection between the lifting plate 2 and the adjusting screw 8. The thread groove corresponding to the pitch screw 8; the fixed gear 9 is slidably connected with the adjusting screw 8, and a plurality of connecting card grooves 12 are opened on the side wall of the adjusting screw 8. The inner wall of the fixed gear 9 is also fixedly connected with a connecting card block 11 matching each connecting card groove 12. When the lifting plate 2 moves upward, the adjusting screw 8 will move along with it, so the fixed gear 9 also moves upward. Under the action of the fixed rack, the fixed gear 9 rotates clockwise, so that the adjusting screw 8 also rotates clockwise. Under the action of the thread groove, the adjusting screw 8 will move to the left when it rotates, thereby pushing the adjusting block 6 and the fixed plate 5 to move to the left, so that the fixed plate 5 fixes the pipe;

[0022] The clamping structure includes a connecting block 13 slidably connected to the side wall of the fixed plate 5, the connecting block 13 is arranged at one side of the vertical end of the fixed plate 5 close to the fixed frame 1, a sliding block 14 is fixedly connected to the side wall of the connecting block 13, a vertically arranged connecting spring 16 is fixedly connected to the bottom wall of the sliding block 14, the other end of the connecting spring 16 is fixedly connected to the lower inner wall of the sliding groove 15, a sliding groove 15 corresponding to the sliding block 14 is provided on the fixed plate 5, the sliding groove 15 runs through the left and right ends of the fixed plate 5, a connecting shaft 17 is rotatably connected between the connecting blocks 13, a fixed pressure plate 18 is fixedly sleeved on the connecting shaft 17, a moving groove is provided on the top of the fixed pressure plate 18, a fixed shaft 19 is slidably connected between the front and rear inner side walls of the moving groove, a mounting rod 21 is rotatably sleeved on the fixed shaft 19, the side wall of the sliding block 14 away from the connecting block 13 is fixedly connected to the fixing rod 20 through the mounting block, and the other end of the mounting rod 21 is rotatably connected to the fixed The top of the fixed plate 5 is fixedly connected with a connecting rod 22, and the two connecting rods 22 are respectively arranged on the left and right sides of the mounting rod 21. The two connecting rods 22 are fixedly connected with a central axis 23 on the side wall of the side close to the mounting rod 21. The other end of the central axis 23 is rotatably connected to the side wall of the mounting rod 21, and the central axis 23 is connected to the middle of the connecting rod 22. When the pipe and the bottom wall of the fixed pressure plate 18 are in contact, the side wall of the pipe will squeeze the fixed pressure plate 18, so that the fixed pressure plate 18 moves upward, thereby driving the sliding block 14 to move upward. When the sliding block 14 moves upward, the fixed rod 20 will move accordingly, so that the end of the mounting rod 21 located on the fixed rod 20 moves upward. Under the action of the central axis 23, the end of the mounting rod 21 away from the fixed rod 20 moves back downward, so that the end of the fixed pressure plate 18 away from the connecting axis 17 rotates downward to press the pipe, thereby firmly fixing the pipe.

[0023] The fixing frame 1, the lifting plate 2 and the fixing plate 5 are all made of aluminum alloy material, so the weight of the device is relatively low.

[0024] In the present invention, when the device is in use, the pipe is first placed on the lifting plate 2, and then the pushing cylinder 3 is started. The pushing cylinder 3 pushes the pushing rod 4 to move, so that the lifting plate 2 and the pipe move upward together. When the lifting plate 2 moves upward, the adjusting screw 8 will move together, so the fixed gear 9 also moves upward. Under the action of the fixed rack, the fixed gear 9 rotates clockwise, so that the adjusting screw 8 also rotates clockwise. Under the action of the thread groove, the adjusting screw 8 moves to the left when it rotates, thereby pushing the adjusting block 6 and the fixed plate 5 to move to the left, so that the fixed plate 5 and the vertical end of the fixed frame 1 fix the pipe together, and at the same time, one end of the fixed plate 5 will make the pipe contact with the bottom wall of the fixed pressure plate 18, so the side wall of the pipe will squeeze the fixed pressure plate 18, so that the fixed pressure plate 18 moves upward, thereby driving the sliding block 14 to move upward, and the sliding When block 14 moves upward, the fixing rod 20 will move accordingly, so that the end of the installation rod 21 located on the fixing rod 20 will move upward. Under the action of the central axis 23, the end of the installation rod 21 away from the fixing rod 20 will move downward, so that the fixed pressure plate 18 away from the end of the connecting shaft 17 will rotate downward to press the pipe, thereby firmly fixing the pipe. Since the device fixes both the left and right ends and the upper and lower ends of the pipe, some pipes with special shapes can also be fixed, thereby facilitating the cutting of the pipe. When cutting, the fixed pressure plate 18 and the fixed plate 5 can prevent the pipe from falling from the lifting plate 2 and causing injuries to workers. By pushing the cylinder 3 to move the push rod 4 downward, the lifting plate 2 also moves downward, causing the pipe to move downward. At the same time, the clamping structure is loosened, and the fixed plate 5 moves in a direction away from the pipe, so that the pipe can be taken out after cutting.
