Technical Field

[0001] The utility model relates to a water conservancy pipeline cutting device, belonging to the technical field of pipeline cutting devices. Background Art

[0002] During the construction of water conservancy and hydropower pipelines, pipe cutting devices are often used to cut the pipes for easy maintenance or laying. Pipe cutting devices of different specifications are used for pipes of different sizes. For pipes with a smaller radius, handheld cutting devices are usually used to increase the convenience of operation.

[0003] When using a cutting device to cut a pipe, the operator usually steps one foot on the surface of the pipe to fix the position of the pipe to prevent the pipe from moving along when the moving cutting device moves on the pipe surface. However, the method of fixing the pipe by stepping on it is less stable, and when the foot steps on the outer surface of a pipe with a slightly larger diameter, slipping may occur easily, causing safety hazards. Summary of the invention

[0004] The utility model aims to solve the problem that when using a cutting device to cut a pipe, an operator usually steps one foot on the surface of the pipe to fix the position of the pipe to prevent the pipe from moving along when the moving cutting device moves on the pipe surface, but the method of fixing the pipe by stepping on the foot is relatively unstable, and when the foot steps on the outer surface of a pipe with a slightly larger diameter, slipping is likely to occur, causing safety hazards. A hydraulic pipe cutting device is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a water conservancy pipeline cutting device, comprising a machine head, a cutting knife is rotatably connected inside the machine head, a rotating rod and two clamping rods are rotatably provided on one side of the machine head, the outer surface of the rotating rod is threadedly connected to the inner wall of the clamping rod, an auxiliary device is provided on one side of the machine head, the auxiliary device comprises a U-shaped rod, the inner wall of the U-shaped rod is threadedly connected to a first screw rod, the bottom end of the first screw rod is rotatably connected to a fan-shaped block, one side of the fan-shaped block is fixedly connected to a positioning rod, one side of the positioning rod slides on one side of the U-shaped rod, a sliding groove is provided on one side of the U-shaped rod, the inner wall of the sliding groove is slidably connected to a cylinder, the inner wall of the cylinder is slidably connected to a round rod, and the end of the round rod away from the cylinder is fixedly connected to one side of the machine head.

At the same time, one end of the cylinder will slide on the inner wall of the slide groove, and the position of the pipe is fixed by the fan-shaped block so that the operator does not need to fix the pipe by other means. When the pipe needs to be rotated, the first screw can be rotated to raise the fan-shaped block to a certain position, and the position fixation of the pipe is released and then the pipe is pushed to rotate.

[0007] Preferably, a grooved plate is fixedly connected to the top end of the first screw rod, and a plurality of through holes are formed on the outer surface of the grooved plate.

[0008] The effect achieved by the above components is that by holding the through hole on the outer surface of the groove plate, the groove plate can be rotated more conveniently to control the first screw to rotate and adjust the position of the sector block.

[0011] Preferably, two sector-shaped pieces are fixedly connected to one side of the machine head, and one side of the sector-shaped pieces slides on the outer surface of the cylinder.

[0012] The effect achieved by the above components is: when the machine head is pulled to make the round rod slide on the inner wall of the cylinder, one side of the two sector pieces will slide on both sides of the cylinder respectively. The sector pieces can further reinforce the mutual angle between the cylinder and the round rod to avoid the angle between the round rod and the cylinder from being deflected as much as possible.

[0017] Preferably, one end of the second screw is fixedly connected to an elastic rope, and one end of the elastic rope away from the second screw is fixedly connected to one side of the threaded ring.

[0018] The effect achieved by the above components is that the threaded ring can be always fixed to one side of the second screw by arranging the elastic rope to prevent the threaded ring from falling off the surface of the second screw when the threaded ring is rotated outwards.

[0019] Preferably, a rubber sheet is fixedly connected to the bottom end of the sliding rod, and a plurality of protrusions are provided on one side of the rubber sheet.

[0020] The effect achieved by the above-mentioned components is that the rubber sheet with a plurality of protrusions on the surface is provided to make the bottom end of the sliding rod more stable and less likely to slide when in contact with the ground.
