[0002] Water supply and drainage pipeline engineering is a pipeline (channel) system engineering for transporting and distributing industrial water supply and domestic drinking water, as well as collecting, transporting and discharging industrial wastewater, domestic sewage and rainwater. Water supply and drainage pipeline engineering is an integral part of the water supply and drainage system and plays an important role in the entire water supply and drainage system. It includes the pipeline (channel) system itself and various structures on the pipeline (channel) system (such as pumping stations, water storage tanks, pipe bridges, gate wells, sewage inspection wells, rainwater inlets, etc.). Its engineering investment accounts for the majority of the total investment in water supply and drainage system engineering. During the laying process of water supply and drainage pipelines, cutting equipment is required to cut the pipelines into pipes of different lengths.

[0003] Currently, the main technology for cutting pipes is to use a handheld cutting machine, but manual cutting is dangerous and the cuts are not very neat. Therefore, a pipe cutting device for water supply and drainage engineering is proposed to optimize and solve the above problems. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0021] Reference Figure 1-3 As shown, a pipe cutting device for water supply and drainage engineering includes an operating table 1, with a cutting mechanism in the middle of the operating table 1 and a clamping mechanism on each side.

[0022] The clamping mechanism includes a fixed frame 2, which is fixed to the operating table 1. Four sets of clamping drive assemblies are arranged in a circumferential array on the inner wall of the fixed frame 2. Each clamping drive assembly includes a first telescopic member 3, a mounting frame 4, a rotating roller 5, and a first motor 6. The first telescopic member 3 is fixed to the inner wall of the fixed frame 2, and the mounting frame 4 is fixed to the end of the push rod of the first telescopic member 3. The rotating roller 5 and the first motor 6 are both mounted on the mounting frame 4, and they are driven by a chain. Furthermore, four sets of clamping assemblies are arranged in a circumferential array on the inner wall of the fixed frame 2. The clamping assemblies and clamping drive assemblies are staggered. Each clamping assembly includes a third telescopic member 7 and a clamp 8. The third telescopic member 7 is fixed to the inner wall of the fixed frame 2, and the clamp 8 is fixed to the end of the push rod of the third telescopic member 7.

[0023] The cutting mechanism includes a second telescopic device 9, a fixed plate 10, a cutting blade 11, and a second motor 12. The second telescopic device 9 is fixed on the inner wall of the operating table 1, and the fixed plate 10 is fixed to the end of the push rod of the second telescopic device 9. The cutting blade 11 and the second motor 12 are both mounted on the fixed plate 10 and are driven by a chain. The central axis of the cutting blade 11 is parallel to the central axis of the rotating roller 5.

[0024] In addition, vertical fourth telescopic devices 13 are installed at both the front and rear ends of the bottom inner side of the control panel 1, and the push rod end of the fourth telescopic device 13 is fixedly connected to an arc-shaped bracket 14.

[0025] More specifically, the first telescopic joint 3, the second telescopic joint 9, the third telescopic joint 7, and the fourth telescopic joint 13 are all electric push rods.

[0026] In use, one end of the pipe is passed horizontally through the two sets of clamping mechanisms, and then both ends of the pipe are placed on the arc-shaped bracket 14. The fourth expansion joint 13 is activated to raise the pipe on the arc-shaped bracket 14 to the center of the two sets of clamping mechanisms. Then, by activating multiple first expansion joints 3 and multiple third expansion joints 7, multiple rotating rollers 5 and multiple clamps 8 are respectively driven to approach the pipe until they are tightly fitted to the outer wall of the pipe, thus completing the fixed clamping of the pipe. At this time, the fourth expansion joint 13 drives the arc-shaped bracket 14 to reset. Then, the second motor 12 in the cutting mechanism is activated to drive the cutting blade 11 to rotate at high speed. The second expansion joint 9 is further activated to drive the high-speed rotating cutting blade 11 on the fixed plate 10 to approach the pipe until the high-speed rotating cutting blade 11 contacts the pipe to perform the cutting operation. Finally, the third expansion joint 7 is activated to drive the clamps 8 away from the pipe, and the first motor 6 is activated to drive the rotating rollers 5 to rotate. In turn, the rotating rollers 5 drive the pipe to rotate, thus cutting the pipe during rotation. Example 2

[0027] As a preferred embodiment of this utility model, this embodiment optimizes the cutting mechanism based on Embodiment 1, specifically as follows:

[0028] In this embodiment, the operating table 1 is provided with two sets of cutting mechanisms arranged symmetrically in the middle. Each cutting mechanism contains two second telescopic devices 9, which are arranged side by side. The push rod ends of both are fixedly connected to the fixed plate 10.

[0029] Reference Figure 3 As shown, four sets of auxiliary support assemblies are provided on the opposite surfaces of the two fixed plates 10. The auxiliary support assemblies include a cylinder 15, a rod 16, a spring 18, and an auxiliary roller 17. The cylinder 15 is fixedly embedded in the fixed plate 10. One end of the rod 16 is slidably connected inside the cylinder 15, and the other end is fixedly connected to the fixing frame of the auxiliary roller 17. The two ends of the spring 18 are fixedly connected to the opposite sides of the fixing frames of the cylinder 15 and the auxiliary roller 17, respectively. The central axis of the auxiliary roller 17 is parallel to the central axis of the cutting blade 11 and is located on the same vertical plane.

[0030] During cutting, the upper and lower cutting mechanisms move synchronously. The auxiliary roller 17 is pressed against the outer wall of the pipe under the action of the spring 18, which together play an auxiliary supporting role in the pipe being cut.

[0031] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
