Description

Technical Field

[0001] This utility model relates to the field of fire protection pipeline cutting technology, specifically to a cutting device for fire protection pipeline installation. Background Technology

[0002] Firefighting pipelines are specialized piping materials used to transport firefighting water or media. They possess characteristics such as pressure resistance, corrosion resistance, and high temperature resistance, and are typically marked with red paint. Their main materials include ductile iron pipes, galvanized steel pipes, stainless steel pipes, alloy pipes, composite pipes, and plastic pipes. Among these, galvanized steel pipes are suitable for fire hydrant systems, ductile iron pipes are mostly used in large-diameter, high-pressure scenarios, and composite pipes combine the advantages of both metallic and non-metallic materials.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1

[0026] Combined with appendix Figure 1-4 A cutting device for fire pipeline installation includes a frame 1, wherein a plurality of rotatable concave support rollers 2 are evenly arranged on the inner side of the top of the frame 1, and a lifting and limiting device 3 that cooperates with the concave support rollers 2 is provided inside the frame 1.

[0027] An L-shaped rod 4 is provided on one side of the frame 1. A telescopic rod 5 is provided on the L-shaped rod 4. An installation plate 6 is provided at the output end of the telescopic rod 5. A fixing device 7 and a cutting device 8 are provided on the installation plate 6 to cooperate with the lifting limit device 3.

[0028] The bottom of the frame 1 is evenly provided with a number of casters 20.

[0029] The casters 20 facilitate the movement of the device by personnel. The personnel place the fire pipe to be cut on the concave support roller 2. The concave support roller 2 can place the fire pipe in the middle position of the concave support roller 2, and at the same time facilitate the movement of the fire pipe. After the fire pipe is aligned with the cutting device 8, the personnel control the lifting limit device 3 to move. The lifting limit device 3 lifts the fire pipe and controls the extension rod 5 to extend. The extension rod 5 drives the fixing device 7 and the cutting device 8 to move downward. The fixing device 7 and the lifting limit device 3 cooperate to fix the fire pipe, and the cutting device 8 can then cut the fire pipe.

[0030] The lifting and limiting device 3 includes a plate 9 disposed within the frame 1. The plate 9 is provided with a lifting telescopic rod 10. The output end of the lifting telescopic rod 10 is provided with a horizontal plate 11. The horizontal plate 11 is provided with a plurality of first V-shaped fixing members 12 disposed between the concave support rollers 2. When the lifting telescopic rod 10 extends, it drives the horizontal plate 11 and the first V-shaped fixing members 12 to lift the fire pipe, so that it is separated from the concave support rollers, preventing the fire pipe from rolling when the cutting device 8 cuts the fire pipe.

[0031] The fixing device 7 includes a plurality of through holes 13 evenly arranged on the mounting plate 6. A movable optical rod 14 is provided in the through hole 13. A second V-shaped fixing member 15 is provided at the bottom of the optical rod 14 and cooperates with the first V-shaped fixing member 12. A spring 16 is fixedly provided on the second V-shaped fixing member 15 and sleeved on the optical rod 14. The other end of the spring 16 is fixedly connected to the mounting plate 6.

[0032] The cutting device 8 includes a cutting motor 17 mounted on the mounting plate 6, and the output end of the cutting motor 17 is provided with a cutting blade 18.

[0033] The extension rod 5 extends, causing the fixing device 7 and the cutting device 8 to move downwards. After the second V-shaped fixing member 15 on the fixing device 7 comes into contact with the fire pipe, the spring 16 contracts under force, and the smooth rod 14 moves upwards towards the mounting plate 6. The cutting blade 18 on the cutting device 8 comes into contact with the fire pipe and cuts the fire pipe.

[0034] Both the first V-shaped fastener 12 and the second V-shaped fastener 15 are equipped with anti-slip pads 19, which can make the fire pipe more securely fixed.

[0035] The telescopic rod 5, the lifting telescopic rod 10, and the cutting motor 17 mentioned in this utility model, as well as their matching power supply and controller, can be provided by the manufacturer. Apart from that, the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.
