[0038] An implementation method of the present application is described in detail below with reference to the accompanying drawings.

[0039] The first implementation method:

[0040] The present invention provides a fire protection pipeline laser cutting machine, please refer to Figure 1-6 , including a pipe cutting platform 1 and a pipe cutting frame 2 installed on the upper end of the pipe cutting platform 1, a laser cutting head 4 is installed on the top inner end of one side of the pipe cutting frame 2, and also includes a limiting mechanism and an alternating driving mechanism 5.

[0041] The limiting mechanism includes a plurality of guide assemblies 3 arranged in sequence along the feeding direction of the fire pipe, and the guide assemblies 3 are installed on the inner side of the pipe cutting frame 2. Specifically, Figure 2 As shown, the guide assembly 3 includes a fixed ring 31 and a plurality of telescopic drive devices 32. The fixed ring 31 is fixed to the inner side of the pipe cutting frame 2. The plurality of telescopic drive devices 32 are evenly distributed and fixed along the circumference of the fixed ring 31. The output end of the telescopic drive device 32 is extended toward the center of the fixed ring 31.

[0042] The telescopic drive device 32 can adopt conventional telescopic drive equipment in the prior art, such as an electric push rod, a cylinder, etc. The output end of the telescopic drive device 32 is used to contact the fire-fighting pipe to limit the position of the fire-fighting pipe, and the fire-fighting pipe can be clamped when necessary.

[0043] Among them, a spherical roller 33 is movably installed at the output end of the telescopic driving device 32, which can reduce the resistance encountered by the fire-fighting pipe during the feeding and rotation process.

[0044] The alternating drive mechanism 5 includes a mounting frame 51, a feeding wheel 52, a rotating wheel 53 and a switching mechanism 56. Specifically, Figure 3 and Figure 4 As shown, the middle part of the mounting frame 51 is horizontally rotatably mounted on the inner top end of the pipe cutting machine frame 2, and the rotation axis of the mounting frame 51 is arranged perpendicular to the feeding direction of the fire-fighting pipe, the feeding wheel 52 is rotatably mounted on one end of the mounting frame 51, and the rotation axis of the feeding wheel 52 is arranged parallel to the rotation axis of the mounting frame 51, and the rotating wheel 53 is horizontally rotatably mounted on the other end of the mounting frame 51, and the rotation axis of the rotating wheel 53 is arranged perpendicular to the rotation axis of the mounting frame 51.

[0045] The switching mechanism 56 is installed between the pipe cutting frame 2 and the mounting frame 51 to drive the mounting frame 51 to rotate around its rotation axis. Regarding the switching mechanism 56, specifically, Figure 4 As shown, the switching mechanism 56 includes a lifting drive device 561, a limit slide frame 562 and a limit rod 563. The lifting drive device 561 is fixed to the inner top end of the pipe cutting machine frame 2, the limit slide frame 562 is fixed to the output end of the lifting drive device 561, the limit rod 563 is horizontally installed on the end surface of the side of the mounting frame 51 away from the power mechanism, and the limit slide frame 562 is sleeved on the outer side of the limit rod 563; in the process of the lifting drive device 561 driving the limit slide frame 562 to lift and lower, the limit rod 563 moves horizontally in the limit slide frame 562, thereby causing the mounting frame 51 to rotate a certain angle along the middle thereof, so that one of the feed wheel 52 and the rotating wheel 53 contacts the fire pipe.

[0046] Among them, the limiting round rod 563 is fixed to the side end of the mounting frame 51, and a plurality of balls in contact with the limiting sliding frame 562 are movably installed on the outer side of the limiting round rod 563 along its circumferential side surface, thereby reducing the resistance of the limiting round rod 563 during horizontal movement in the limiting sliding frame 562.

[0047] The feeding wheel 52 and the rotating wheel 53 are driven together by a power mechanism, and the power mechanism is installed on the mounting frame 51.

[0048] The fire-fighting pipe laser cutting machine is configured by the cooperation of a power mechanism, a feed wheel 52, a rotating wheel 53 and a switching mechanism 56. The switching mechanism 56 can be used to make the feed wheel 52 and the rotating wheel 53 contact the fire-fighting pipe alternately, thereby realizing a stable switching of the feeding and rotating effects on the fire-fighting pipe, which is beneficial to reducing cutting errors. The feed wheel 52 and the rotating wheel 53 are driven together by a power mechanism, which reduces the operating energy consumption of the laser pipe cutting machine.

[0049] The rotating wheel 53 is spherical in shape, and the spherical rotating wheel 53 can meet the rotation driving requirements of fire-fighting pipes with different diameters.

[0050] Regarding the power mechanism, specifically, Figure 3 , Figure 4 and Figure 5 As shown, the power mechanism includes a driving motor 54 and a transmission mechanism 55. The driving motor 54 is fixed to the inner top end of the pipe cutting frame 2, and the output end axis of the driving motor 54 is arranged to coincide with the rotation axis of the mounting frame 51. The transmission mechanism 55 includes a transmission assembly and a reversing assembly. The transmission assembly is installed between the output shaft of the driving motor 54 and the feed wheel 52, and the reversing assembly is installed between the transmission assembly and the rotating wheel 53.

[0051] More specifically, Figure 5 As shown, the reversing assembly includes bevel gear 1 553 and bevel gear 2 554. Bevel gear 2 554 is coaxially fixed with the rotating wheel 53. Bevel gear 1 553 is horizontally rotatably mounted on the mounting frame 51. The rotation axis of bevel gear 1 553 is arranged parallel to the rotation axis of the feed wheel 52. Bevel gear 1 553 is connected to the transmission assembly.

[0052] Among them, the transmission assembly includes a transmission belt 551 and a transmission pulley 552. There are three transmission pulleys 552. The three transmission pulleys 552 are coaxially fixed with the output shaft of the driving motor 54, the rotating shaft of the feed wheel 52 and the rotating shaft of the bevel gear 553 respectively. The transmission belt 551 is installed between the three transmission pulleys 552.

[0053] Working principle: When in use, first, put the fire-fighting pipe along the guide assembly 3, and use the output end of the telescopic driving device 32 to contact the fire-fighting pipe to limit the fire-fighting pipe;

[0054] Next, the switching mechanism 56 is used to make the feed wheel 52 contact with the fire pipe. Specifically, the lifting drive device 561 drives the limit slide frame 562 to move. During this process, the limit round rod 563 moves horizontally in the limit slide frame 562, thereby causing the mounting frame 51 to rotate along the middle thereof by a certain angle, so that the feed wheel 52 contacts with the fire pipe. Then, the power mechanism is used to drive the feed wheel 52 to rotate, and the fire pipe is fed. Figure 7 As shown;

[0055] When the fire-fighting pipe is fed to the preset position, the switching mechanism 56 is used to make the rotating wheel 53 contact with the fire-fighting pipe, specifically: the lifting drive device 561 drives the limit sliding frame 562 to move in the opposite direction. During this process, the limit round rod 563 moves horizontally in the limit sliding frame 562 in the opposite direction, thereby driving the mounting frame 51 to rotate in the opposite direction along the middle part by a certain angle, so that the rotating wheel 53 contacts with the fire-fighting pipe, and then the power mechanism is used to drive the rotating wheel 53 to rotate, drive the fire-fighting pipe to rotate, and cooperate with the laser cutting head 4 to cut the rotating fire-fighting pipe, such as Figure 8 shown.

[0056] The fire-fighting pipe laser cutting machine is configured by the cooperation of a power mechanism, a feed wheel 52, a rotating wheel 53 and a switching mechanism 56. The switching mechanism 56 can be used to make the feed wheel 52 and the rotating wheel 53 contact the fire-fighting pipe alternately, thereby realizing a stable switching of the feeding and rotating effects on the fire-fighting pipe, which is beneficial to reducing cutting errors. The feed wheel 52 and the rotating wheel 53 are driven together by a power mechanism, which reduces the operating energy consumption of the laser pipe cutting machine. Among them, the rotating wheel 53 is spherical in shape, and the spherical rotating wheel 53 can adapt to the rotation drive requirements of fire-fighting pipes of different diameters.

[0057] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
