[0025] A ruler rod 12 is slidably mounted on the outer wall of one side of the placement seat 1, and a scale is provided on the top of the ruler rod 12. The end face of the ruler rod 12 away from the first portal frame 2 is the zero point of the scale. A positioning baffle 14 is provided on the end of the ruler rod 12 away from the first portal frame 2, and the positioning baffle 14 is in contact with the ruler rod 12. A driven block 15 is fixedly mounted on the bottom of the ruler rod 12. A second screw rod 16 located below the ruler rod 12 is rotatably mounted on the outer wall of one side of the placement seat 1. The second screw rod 16 penetrates the driven block 15 and is threadedly connected with the driven block 15.

[0027] In this embodiment, the cutting structure specifically includes a second gantry 5, a hydraulic cylinder 6, a lifting seat 7, a rotating shaft 8, a cutting wheel 9 and a motor 11.

The output end of the hydraulic cylinder 6 extends into the second gantry 5 and is fixedly connected to the connecting cover 10. After the motor 11 is started, the cutting wheel 9 is driven to rotate. After the output end of the hydraulic cylinder 6 is started and extended downward, the cutting wheel 9 that is continuously rotating at a high speed can be rotated downward, thereby realizing automatic cutting of the pressure pipeline.

[0028] In this embodiment, in order to be able to cut pressure pipes of different diameters within a certain range, a V-shaped groove 101 is provided on the top of the placement seat 1 , and a rubber protective pad is fixedly installed in the V-shaped groove 101 .

[0029] In this embodiment, in order to adjust the position of the positioning baffle 14 so as to limit and block pressure pipes of different diameters, a fixed shaft 13 is fixedly installed at one end of the ruler rod 12 away from the first gantry 2, and the positioning baffle 14 is rotatably sleeved on the fixed shaft 13. Through this design, the limit blocking position of the positioning baffle 14 can be adjusted in a rotating manner. A hexagonal rod 17 is fixedly installed at one end of the fixed shaft 13 away from the ruler rod 12, and a moving piece 18 is slidably sleeved on the hexagonal rod 17. A hexagonal hole is opened on the moving piece 18, which is slidably sleeved on the hexagonal rod 17 through the hexagonal hole. An end plate 19 is fixedly installed on one end of the hexagonal rod 17 away from the fixed shaft 13, and the hexagonal rod A retaining spring 20 is sleeved on 17, one end of the retaining spring 20 is fixedly connected to the end plate 19, and the other end is fixedly connected to the moving piece 18. A locking rod 21 is fixedly installed on the outer wall of the moving piece 18 away from the end plate 19. A plurality of slots 1401 distributed in a circular array are opened on the outer wall of the positioning baffle 14 away from the ruler rod 12. One end of the locking rod 21 away from the moving piece 18 extends into one of the slots 1401. After adjusting the position of the positioning baffle 14, the locking rod 21 is used to limit the positioning baffle 14 so that the positioning baffle 14 is maintained at the current position. In order to facilitate the operation of the moving piece 18, an open pull ring is fixedly installed on the moving piece 18.

[0030] The working principle of the pipe cutting equipment for pressure pipe installation and construction provided by the utility model is as follows:

[0031] When in use, the distance between the positioning baffle 14 and the placement seat 1 (hereinafter referred to as the cutting distance) is adjusted according to the length of the pressure pipe to be cut off. When adjusting, the second screw rod 16 is rotated forward or reversely. During the rotation process, the second screw rod 16 will drive the driven block 15 to move forward or backward, and the driven block 15 drives the ruler rod 12 to move accordingly, and the ruler rod 12 drives the positioning baffle 14 to move. At the same time, during the adjustment process, by observing the scale value corresponding to the indicator rod 22 on the ruler rod 12, the cutting distance can be determined. When the cutting distance reaches the predetermined value, the second screw rod 16 can be stopped from rotating;

[0032] After completing the above operations, the pressure pipe to be cut is placed in the V-shaped groove 101 in the placement seat 1, and then the pressure pipe is pushed forward until the front end of the pressure pipe contacts the positioning baffle 14, and then the first screw rod 3 is rotated clockwise. The first screw rod 3 will move downward during the clockwise rotation, and the first screw rod 3 drives the pressure block 4 and the rubber resistance block to move downward, and finally the resistance block will be pressed tightly against the top of the pressure pipe, and then the motor 11 is started to run, and the motor 11 drives the fixed shaft 13 to rotate at a high speed, and the fixed shaft 13 drives the cutting wheel 9 to rotate in height, and then the output end of the hydraulic cylinder 6 is started to extend downward, and the hydraulic cylinder 6 pushes the lifting seat 7 to move downward, so that the cutting wheel 9 that is constantly rotating in height moves downward. As the cutting wheel 9 continues to descend, the part of the pressure pipe between the placement seat 1 and the positioning baffle 14 can be cut off, thereby completing the cutting. When a batch of pressure pipes need to be cut of the same length, after completing the cutting work of the first pressure pipe, there is no need to adjust the cutting distance for the subsequent pressure pipes.

[0033] When the diameter of the pressure pipe is relatively large or relatively small, causing it to be too high or too low after being placed on the placement seat 1, the pressure pipe can be positioned and blocked by the position of the positioning baffle 14. When adjusting, first hook the open pull ring and pull the movable sheet 18 in the direction away from the ruler rod 12. The movable sheet 18 drives the locking rod 21 to move, so that the locking rod 21 withdraws from the previous slot 1401, so that the positioning baffle 14 loses its restriction, and then the positioning baffle 14 can be rotated upward or downward. When the position of the positioning baffle 14 is appropriate, slowly release the open pull ring and reinsert the locking rod 21 into the slot 1401 that is currently expected to be axially aligned.

Through the arrangement of a first gantry 2, a first screw rod 3, and a pressure block 4, the pressure pipe can be pressed and fixed to prevent the pressure pipe from moving during cutting, and the device has the advantage of reliable use. Through the arrangement of a cutting structure composed of a hydraulic cylinder 6, a lifting seat 7, a cutting wheel 9, a motor 11, and other components, the pressure pipe can be automatically cut, and the device has the advantage of labor saving. Through the arrangement of a ruler rod 12, a positioning baffle plate 14, a driven block 15, a second screw rod 16, and an indicating rod 22, a scale is arranged on the ruler rod 12, and the positioning baffle plate 14 can be adjusted by rotating the second screw rod 16. 4 and the placement seat 1, and observe the scale value indicated by the indicator rod 22 during the adjustment process, so that the user can accurately control the cutting distance.
