After the cutting is completed, the mobile flip unit can move the pipe to the discharge end, and flip the pipe to the discharge inclined plate 2 for discharge.

[0021] In some preferred embodiments, the mobile flipping unit includes a mobile plate 4, which is slidably arranged on the upper end surface of the base 1, has a corresponding supporting force, and is connected to a push-pull drive. Here, the push-pull drive can be a hydraulic push rod, and the telescopic end is connected to the end of the mobile plate 4 away from the discharge end. The hydraulic push rod is driven, and the mobile plate 4 can slide along the approach to and away from the discharge end; the support member 5 is arranged above the mobile plate 4, has a corresponding supporting force, and is connected to the mobile plate 4 through the flipping unit. Preferably, the support member 5 is L-shaped, and a supporting working surface is formed on the inner side, and support rollers 13 are rotatably installed on the support working surface. The support rollers 13 are arranged in an array at intervals. After changing the cutting position, they continue to advance along the length direction of the support member 5. The support rollers 13 arranged along the length facilitate the pushing of the fire-fighting pipe; the flipping unit is arranged on the mobile plate 4 and is located at both ends of the support member 5 to perform corresponding flipping operations;

[0022] Among them, the flipping unit includes a flipping shaft 14, which is mounted above the moving plate 4 through a group of fixed side plates and is rotatably connected to the fixed side plates. The flipping shaft 14 is fixedly connected to the corner of the support member 5; the flipping cylinder 6 is mounted on the moving plate 4 through the fixed side plates, and the fixed end of the flipping cylinder 6 is hinged to the fixed side plates, and the telescopic end is hinged to a corresponding rotating distal end of the support member 5; the support block 15 is assembled on the side of the moving plate 4 close to the discharging end and can be supported on the other rotating distal end of the support member 5. When the telescopic end of the flipping cylinder 6 is telescoped, the support member 5 can be rotated and flipped along the flipping shaft 14. When moving to the bottom of the positioning operation, the positioning member is flipped to a V shape, and the fire-fighting pipe is positioned in cooperation with the fixed member 9 and the movable member 10; when moving to the discharging end, the positioning member is reset, that is, flipped to an L shape, so that the fire-fighting pipe on the positioning member rolls to the discharging inclined plate 2 for discharging.

[0023] In some preferred embodiments, the adjustment positioning unit is arranged on the supporting upper plate 3, and the positioning height is adjusted by the lifting rod 8, and the corresponding positioning operation is performed at a predetermined height. It should be noted that the lifting rod 8, hydraulic push rod, etc. in the present application are all connected to the hydraulic working system.

[0024] Among them, the adjustment and positioning unit includes a fixed transverse plate 7, which is located below the supporting upper plate 3, connected to the telescopic end of the lifting rod 8, and has corresponding supporting force; a fixed part 9 and a movable part 10, which are fixedly installed at both ends of the fixed transverse plate 7, and the movable part 10 is displaced along the length direction of the fixed transverse plate 7 between the two fixed plates, and the bottom arc-shaped concave of the fixed part 9 and the movable part 10 forms a positioning groove 11; a positioning ruler 12, which is assembled between the two fixed plates, and a scale is set on the outer surface. The positioning ruler 12 is in contact with one side of the movable part 10 and can slide in contact. A positioning strip is set at the corresponding position on the movable part 10 to facilitate observation of the corresponding scale after the movable block moves. When positioning the cutting site, the pressing position of the movable part 10 can be changed to confirm the cutting site. After marking, the movable part 10 can be moved again to position the pipeline near the cutting position.

[0025] In this embodiment, the movable part 10 is connected to the mobile drive, and a sliding groove is provided on the fixed horizontal plate 7. The fixed plate slides along the sliding groove through the limiter 18. The mobile drive includes a support screw 16 that passes through the movable part 10. The support screw 16 is threadedly connected to the movable part 10, and both ends are rotatably connected to the fixed part 9, and one end of the support screw 16 extends out of the corresponding fixed part 9 to connect the drive motor 17. The output end of the drive motor 17 is fixedly connected to one end of the support screw 16. After the drive motor 17, the output end of the drive motor 17 rotates to drive the support screw 16 to rotate. At this time, the movable part 10 slides along the sliding groove, changes the positioning position of the positioning groove 11 of the movable top part, and cooperates with the positioning groove 11 of the fixed part 9 to perform three-point positioning of the pipeline. The distance between the positioning groove 11 of the movable part 10 and the positioning groove 11 of the fixed part 9 can be changed. When the pipeline cutting equipment (such as the cutting equipment connected to the mechanical arm) is cutting, the cutting can be performed between the fixed and movable positioning points to ensure the stability of the pipeline during cutting.

[0026] When in use, the device is placed in a suitable working position; in the initial state, the movable plate 4 is located below the supporting upper plate 3, and the support member 5 is flipped into a V shape (in the present application, the direction of the opening after the V-shaped to L-shaped support member 5 is flipped, and the angle is always 90 degrees). The fire-fighting pipe to be cut is pushed onto the support along the support roller 13, and the front end is located at a specific position at one end of the support member 5 (to facilitate the scale counting of the positioning ruler 12 and determine the length of the pipe. For example, the length of the support member 5 can be a predetermined length, and the vertical distance between one end and the fixed member 9 is predetermined); start the drive motor 17, and after the movable member 10 moves to the cutting site, it is marked, and then the movable member 10 is continued to be moved to position the pipe near the marked cutting site; when positioning the pipe, the lifting rod 8 is controlled to extend and retract to press down the fixed member 9 and the movable member 10, so that the inner side of the positioning groove 11 contacts the outer wall of the pipe, and pipes of different outer diameters are positioned, and then the pipe cutting equipment is used to cut them.

[0027] After the cutting is completed, the positioning member and the movable member 10 can be lifted up, the movable plate 4 moves toward the discharge end, the turning cylinder 6 works to transform the support member 5 into an L shape, and the cut pipe is sent to the discharge inclined plate 2 for discharge.
