Description

Technical Field

[0001] The present invention relates to the technical field of pipe cutting equipment, in particular to a pipe cutting machine with a pipe rotary cutting function. Background Art

[0002] During the construction of water conservancy projects, pipelines are needed to regulate and control surface water and groundwater. During the construction of pipelines, cutting is required to meet the construction and installation requirements. The above cutting methods mostly use saw blades or flame cutting;

[0003] During the flame cutting process, as the pipe continues to rotate, the nozzle will complete the cutting process of the pipe. However, since the flame nozzle needs to be closed in an orderly manner and then the power supply of the equipment is cut off, the flame will remain for a period of time after the cutting is completed. At this time, the flame will burn the outer wall of the pipe, causing the edge of the pipe to deform slightly due to the high temperature. To solve the above problems, the following solutions are proposed. Summary of the Invention

[0019] The transmission member includes a rotating wheel fixedly connected to the side wall of the rotating rod;

[0020] When the pipe is placed on the inner wall of the mounting platform, due to the heavy weight of the metal pipe, the pipe will force the contact assembly to rotate around the rotating rod.

[0021] Preferably, the steering mechanism comprises:

[0022] An energy storage component is fixedly connected to a side wall of the moving platform through a limiting member;

[0023] The limiting member includes a fixing rod fixedly connected to the side wall of the moving platform, and a rotating disk is rotatably connected to the side wall of the fixing rod;

[0024] A spray gun assembly, the spray gun assembly is fixedly connected to the side wall of the rotating disk through a positioning piece;

[0025] The positioning member includes a rotating square rod fixedly connected to the side wall of the rotating disk, a flame spray gun fixedly connected to the side wall of the rotating square rod, and a gas pipe is connected to the top of the flame spray gun;

[0026] Among them, after the pipe is placed firmly, the flame spray gun sprays flames to cut the outer wall of the pipe, and at this time the rotating column 2 will drive the pipe to rotate in a circle to complete the basic cutting process.

[0027] Preferably, the rolling assembly includes a plurality of rotating columns rotatably connected to the inner wall of the mounting platform;

[0037] Preferably, the spray gun assembly includes a right-angle rod fixedly connected to the side wall of the rotating square rod, and a right-angle plate is fixedly connected to the side wall of the movable platform;

[0038] When the spray gun assembly is not in use, the flame spray gun and the bottom fixing frame are in a horizontal state. After the pipeline is placed on the top of the rolling assembly, the pressure generated forces the flame spray gun to rotate downward.

[0039] The present invention has the following beneficial effects:

[0040] (1) After the device of the present invention completes the cutting, the pipe will be divided into two parts, namely the main body and the cut end. The main body is still on the top of the rotating column, while the cut end will fall downward due to the loss of restraint, showing as follows Figure 11 When the cut end is completely separated from the curved plate, the pressure on the top of the curved plate is lost, and the torsion spring will release the mechanical power, forcing the rotating disk and the flame spray gun to reset at the same time, away from the outer wall of the pipe. Through the application of the above components, the equipment can ensure that the flame spray gun can quickly move away from the cutting area after the cutting is completed. The high temperature flame of the flame spray gun causes slight deformation of the edge of the pipe.

[0041] (2) The present invention utilizes the characteristics of the flame spray gun in cutting pipes and sets the flame spray gun at the vertical top of the pipe. With the above design, the flame spray gun will show the following when the pipe cutting is about to be completed. Figure 10 state, at this time Figure 10 The position of G in the middle is the only remaining connection point between the main body and the cut end. At this time, all the pressure of the cut end will act on the end position of the arc plate, that is, Figure 10 The L position in the middle forces the curved plate to always face downward, ensuring that the flame spray gun is always perpendicular to the pipe before completing the thorough cutting. This prevents the curved plate from rotating due to the reduction in the space between the main body and the cut end, which ultimately causes the cutting path of the flame spray gun to change and affects the flatness of the cutting area.

[0042] (3) The present invention utilizes the characteristic of the rotating square rod to generate rotation, and a right-angle rod and a right-angle plate are arranged inside the equipment. When the rotating disk and the rotating square rod rotate, the rotating square rod will drive the right-angle rod to contact the plane of the right-angle plate, so that the flame spray gun and the right-angle plate form a horizontal state. Through the application of the above components, after the pipeline drives the arc plate to rotate downward to the lowest position, the flame spray gun can form a vertical state with the pipeline, thereby accelerating the early positioning efficiency of the equipment.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] For example 1, please refer to Figure 1-Figure 7 The present invention is a pipe cutting machine with a pipe rotary cutting function, comprising a fixed frame 13, a support rail 14 fixedly connected to the top of the fixed frame 13, an operating table 15 fixedly connected to the side wall of the fixed frame 13, and a movable table 16 fixedly connected to the side wall of the fixed frame 13, and further comprising:

[0059] The pressure mechanism 1 is fixedly connected to the inner wall of the fixing frame 13 and is used to drive the pipeline to rotate;

[0060] A steering mechanism 3, which is fixedly connected to the side wall of the movable platform 16 and is used for flame cutting the pipe;

[0061] The linkage mechanism 2 is fixedly connected to the side wall of the pressure mechanism 1 and is used to contact the outer wall of the pipe and drive the steering mechanism 3 to rotate after the pipe is cut;

[0062] Before use, the pipe is first placed on the inner wall of the fixed frame 13 , and then the staff forces the moving platform 16 to drive the steering mechanism 3 to move to the cutting area through the operating platform 15 .

[0063] The pressure mechanism 1 comprises:

[0064] The rolling assembly 11 is fixedly connected to the inner wall of the fixing frame 13 through a support member;

[0065] The support member includes a fixing plate 111 fixedly connected to the inner wall of the fixing frame 13, and a mounting platform 112 is fixedly connected to the top of the fixing plate 111;

[0066] The driving assembly 12 is rotatably connected to the inner wall of the mounting platform 112 via a rotating member;

[0067] The rotating member includes two supporting round rods 122 rotatably connected to the inner wall of the mounting platform 112, and a belt 123 is sleeved on the outer wall of the two supporting round rods 122;

[0068] Before use, the pipe is placed on the top of the second rotating column 121, and during operation, the second rotating column 121 drives the pipe to rotate.

[0069] The linkage mechanism 2 includes:

[0070] The contact assembly 21 is fixedly connected to the side wall of the mounting platform 112 through a steering member;

[0071] The steering member includes a mounting frame 211 fixedly connected to the side wall of the mounting platform 112, and a rotating rod 212 fixedly connected to the inner wall of the mounting frame 211;

[0072] The linkage assembly 22 is fixedly connected to the side wall of the rotating rod 212 through a transmission member;

[0073] The transmission member includes a rotating wheel 221 fixedly connected to the side wall of the rotating rod 212;

[0074] When the pipe is placed on the inner wall of the mounting platform 112 , due to the heavy weight of the metal pipe, the pipe will force the contact assembly 21 to rotate around the rotating rod 212 .

[0075] The steering mechanism 3 includes:

[0076] Energy storage assembly 31, the energy storage assembly 31 is fixedly connected to the side wall of the movable platform 16 through a limiting member;

[0077] The limiting member includes a fixed rod 311 fixedly connected to the side wall of the movable platform 16, and a rotating disk 312 is rotatably connected to the side wall of the fixed rod 311;

[0078] The spray gun assembly 32 is fixedly connected to the side wall of the rotating disk 312 through a positioning member;

[0079] The positioning member includes a rotating square rod 321 fixedly connected to the side wall of the rotating disk 312, a flame spray gun 322 fixedly connected to the side wall of the rotating square rod 321, and a gas pipe 323 is connected to the top of the flame spray gun 322;

[0080] After the pipe is placed securely, the flame spray gun 322 sprays flames to cut the outer wall of the pipe, while the rotating column 121 drives the pipe to rotate in a circle, completing the basic cutting process.

[0081] The operator uses the operating table 15 to force the movable table 16 to drive the steering mechanism 3 to move to the cutting area. After confirming the cutting position, the flame spray gun 322 is activated, forcing the flame spray gun 322 to spray flames onto the outer wall of the pipe. At this time, the CNC motor 124 drives the supporting round rod 122 and the second rotating column 121 to rotate through the output rod 125 and the belt 123. The second rotating column 121 forces the top pipe to rotate, changing the cutting position of the flame spray gun 322 on the pipe.

[0082] For example 2, please refer to Figure 3-Figure 11 The present invention is a pipe cutting machine with a pipe rotary cutting function. Based on Example 1, the rolling assembly 11 includes a plurality of rotating columns 113 rotatably connected to the inner wall of the mounting platform 112;

[0083] When the second rotating column 121 drives the pipe to rotate, the outer walls of the first rotating column 113 will contact the pipe and assist the pipe to rotate.

[0084] When the pipe is placed on top of the rolling assembly 11, the pressure of the pipe itself will force the arc plate 213 to rotate counterclockwise, showing the following Figure 5 state, and at this time the arc plate 213 drives the rotating wheel 221 to rotate in the same direction through the rotating rod 212, and the rotating wheel 221 drives the rotating disk 312 to rotate along the outer wall of the fixed rod 311 through the transmission belt 222. At the same time, the torsion spring 1 313 is compressed and deformed, and the rotating disk 312 drives the flame spray gun 322 to be perpendicular to the outer wall of the pipe through the rotating square rod 321, so that the flame spray gun 322 enters the cutting state.

[0085] The drive assembly 12 includes a CNC motor 124 fixedly connected to the bottom of the fixed plate 111. The output end of the CNC motor 124 is fixedly connected to the output rod 125. The end of the belt 123 away from the two supporting round rods 122 is rotatably connected to the outer wall of the output rod 125.

[0086] The rotational force generated by the CNC motor 124 drives the supporting rod 122 and the second rotating column 121 to rotate in the same direction through the output rod 125 and the belt 123;

[0087] After the equipment completes the cutting, the pipe will be divided into two parts, namely the main body and the cut end. The main body is still on the top of the rotating column 113, while the cut end will fall down due to the loss of restraint, showing as follows. Figure 11 When the cut end is completely separated from the curved plate 213, the pressure on the top of the curved plate 213 is lost, and the torsion spring 313 will release the mechanical power, forcing the rotating disk 312 and the flame spray gun 322 to reset at the same time and move away from the outer wall of the pipe. Through the application of the above components, it is ensured that after the equipment completes cutting, the flame spray gun 322 can quickly move away from the cutting area, and the high temperature flame of the flame spray gun 322 causes slight deformation of the edge of the pipe.

[0088] The contact assembly 21 includes an arc-shaped plate 213 fixedly connected to the side wall of the rotating rod 212, and an inclined contact block 214 is fixedly connected to the outer wall of the arc-shaped plate 213;

[0089] During the placement process, the pipe contacts the outer wall of the inclined contact block 214, forcing the arc plate 213 to rotate counterclockwise around the rotating rod 212, thereby driving the rotating wheel 221 to rotate.

[0090] By utilizing the characteristics of the flame spray gun 322 in cutting the pipe, the flame spray gun 322 is set at the vertical top of the pipe. With the above design, the flame spray gun 322 will show the following when the pipe cutting is about to be completed. Figure 10 state, at this time Figure 10 The position of G in the middle is the only remaining connection point between the body and the cut end. At this time, all the pressure of the cut end will act on the end position of the arc plate 213, that is, Figure 10 The L position in the middle forces the curved plate 213 to remain in a downward position, ensuring that the flame spray gun 322 is always perpendicular to the pipe before completing the complete cutting, and preventing the curved plate 213 from rotating due to the reduction in the distance between the main body and the cut end, which ultimately causes the cutting path of the flame spray gun 322 to change and affects the flatness of the cutting area.

[0091] The linkage assembly 22 includes a transmission belt 222 sleeved on the outer wall of the rotating wheel 221, and one end of the transmission belt 222 away from the rotating wheel 221 contacts the outer wall of the rotating disk 312;

[0092] When the rotating wheel 221 drives the transmission belt 222 to rotate, the transmission belt 222 drives the rotating disk 312 to rotate.

[0093] The energy storage assembly 31 includes a torsion spring 1 313 fixedly connected to the inner wall of the fixed rod 311, and one end of the torsion spring 1 313 away from the fixed rod 311 is fixedly connected to the inner wall of the rotating disk 312;

[0094] When the rotating disk 312 rotates, the rotating disk 312 forces the torsion spring 1 313 to deform and accumulate mechanical power to provide power for the subsequent reset of the spray gun assembly 32 .

[0095] The spray gun assembly 32 includes a right-angle rod 324 fixedly connected to the side wall of the rotating square rod 321, and a right-angle plate 325 fixedly connected to the side wall of the movable platform 16;

[0096] When the spray gun assembly 32 is not in use, the flame spray gun 322 and the bottom fixing frame 13 are in a horizontal state. After the pipeline is placed on the top of the rolling assembly 11, the pressure generated forces the flame spray gun 322 to rotate downward;

[0097] Taking advantage of the rotation characteristics of the rotating square rod 321, a right-angle rod 324 and a right-angle plate 325 are provided inside the equipment. When the rotating disk 312 and the rotating square rod 321 rotate, the rotating square rod 321 will drive the right-angle rod 324 to contact the plane of the right-angle plate 325, so that the flame spray gun 322 and the right-angle plate 325 form a horizontal state. Through the application of the above components, after the pipeline drives the curved plate 213 to rotate downward to the lowest position, the flame spray gun 322 can form a vertical state with the pipeline, thereby accelerating the early positioning efficiency of the equipment.

[0098] A specific application of this embodiment is: before using the present invention, the pipeline is placed on the top of the two sets of pressure mechanisms 1, and the pipeline is presented as follows: Figure 1 state, and part of the pipe will press the curved plate 213, forcing the curved plate 213 to rotate around the rotating rod 212. After the staff confirms that the rotating column 121 can drive the pipe to rotate, the staff forces the moving platform 16 to drive the steering mechanism 3 to move to the cutting area through the operating table 15. After confirming the cutting position, the flame spray gun 322 is started, forcing the flame spray gun 322 to spray flame onto the outer wall of the pipe. At this time, the CNC motor 124 drives the supporting round rod 122 and the rotating column 121 to rotate through the output rod 125 and the belt 123. The rotating column 121 will force the top pipe to rotate, changing the cutting position of the flame spray gun 322 on the pipe.

[0099] When the pipe is placed on top of the rolling assembly 11, the pressure of the pipe itself will force the arc plate 213 to rotate counterclockwise, showing the following Figure 5 At this time, the arc plate 213 drives the rotating wheel 221 to rotate in the same direction through the rotating rod 212, and the rotating wheel 221 drives the rotating disk 312 to rotate along the outer wall of the fixed rod 311 through the transmission belt 222. At the same time, the torsion spring 1 313 is compressed and deformed, and the rotating disk 312 drives the flame spray gun 322 to be perpendicular to the outer wall of the pipe through the rotating square rod 321, so that the flame spray gun 322 enters the cutting state;

[0100] After the equipment completes the cutting, the pipe will be divided into two parts, namely the main body and the cut end. The main body is still on the top of the rotating column 113, while the cut end will fall downwards due to the loss of restraint, showing as follows: Figure 11 In the state F, after the cut end is completely separated from the curved plate 213, the pressure on the top of the curved plate 213 is lost, and the torsion spring 1 313 will release the mechanical power, forcing the rotating disk 312 and the flame spray gun 322 to reset at the same time and move away from the outer wall of the pipe. Through the application of the above components, the flame spray gun 322 can be quickly moved away from the cutting area after the equipment completes the cutting, and the high temperature flame of the flame spray gun 322 causes slight deformation of the edge of the pipe.

[0101] By utilizing the characteristics of the flame spray gun 322 in cutting the pipe, the flame spray gun 322 is set at the vertical top of the pipe. With the above design, the flame spray gun 322 will show the following when the pipe cutting is about to be completed. Figure 10 state, at this time Figure 10 The position of G in the middle is the only remaining connection point between the body and the cut end. At this time, all the pressure of the cut end will act on the end position of the arc plate 213, that is, Figure 10 The L position in the middle forces the curved plate 213 to always face downward, ensuring that the flame spray gun 322 is always in a vertical state with the pipe before completing the thorough cutting, and preventing the curved plate 213 from rotating due to the reduction in the space between the main body and the cut end, which ultimately causes the cutting path of the flame spray gun 322 to change and affects the flatness of the cutting area.

[0102] Taking advantage of the rotation characteristics of the rotating square rod 321, a right-angle rod 324 and a right-angle plate 325 are provided inside the equipment. When the rotating disk 312 and the rotating square rod 321 rotate, the rotating square rod 321 will drive the right-angle rod 324 to contact the plane of the right-angle plate 325, so that the flame spray gun 322 and the right-angle plate 325 form a horizontal state. Through the application of the above components, after the pipeline drives the curved plate 213 to rotate downward to the lowest position, the flame spray gun 322 can form a vertical state with the pipeline, thereby accelerating the early positioning efficiency of the equipment.
