Description

Technical Field

[0001] This utility model relates to the field of gas cutting machine technology, and in particular to a gas cutting machine for seamless steel pipes. Background Technology

[0002] A seamless steel pipe gas cutting machine is a device specifically designed for cutting seamless steel pipes. By combining a high-temperature flame with a high-pressure oxygen flow, it can quickly cut seamless steel pipes of different materials and thicknesses. It has high cutting efficiency and is widely used in pipeline processing in industries such as petroleum, chemical, shipbuilding, and construction.

[0003] When cutting steel pipes using a seamless steel pipe gas cutting machine, combustible gases such as oxy-acetylene or oxy-propane and high-pressure oxygen are introduced into the pipe. These gases are then delivered to the cutting torch head through a hose. There are usually three hoses: two for delivering the high-pressure oxygen flow and one for delivering the combustible gas. To reduce the limitations of hose length on the cutting operation, the hoses are usually designed to be quite long. However, this also means that during operation, an excessively long hose may droop onto the steel pipe, obstructing the movement of the permanent magnet wheel of the gas cutting machine and hindering its normal operation. Utility Model Content

[0004] This utility model is a seamless steel pipe gas cutting machine proposed to solve the problem that excessively long hoses may droop onto the steel pipe during the operation of a gas cutting machine, obstructing the movement of the permanent magnet wheel of the gas cutting machine and hindering the normal operation of the seamless steel pipe gas cutting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a seamless steel pipe gas cutting machine, comprising a gas cutting machine body, with permanent magnet wheels rotatably installed at the four corners of the bottom of the gas cutting machine body, and three hoses (generally two of which are used to transport high-pressure oxygen flow and the other is used to transport combustible gas) provided on one side of the top of the gas cutting machine body, with the same cutting torch head installed at one end of the three hoses, and an electric telescopic rod installed on one side of the gas cutting machine body, one end of which is fixedly installed on the outer surface of the cutting torch head, and a support device provided on the outer surface of the three hoses, wherein the support device supports and limits the three hoses by setting a rectangular rod that can extend and retract in a rectangular tube.

[0006] The effect achieved by the above components is as follows: by setting a rectangular rod, the rectangular rod can slide on the inner wall of the rectangular tube, which makes it easy to adjust the height of the rectangular rod according to the actual length of the hose. When the top of the rectangular rod abuts against the hose, the hose is fully stretched, which can support and limit the hose. This helps to prevent the hose from hanging on the steel pipe and obstructing the movement of the permanent magnet wheel of the gas cutting machine, thus facilitating the normal operation of the seamless steel pipe gas cutting machine.

[0007] Preferably, the support device includes an extension plate, a rectangular tube is provided on the top of the extension plate, a disassembly assembly is provided between the rectangular tube and the extension plate, a rectangular rod is slidably installed on the inner wall of the rectangular tube, a support plate is fixedly installed on the top of the rectangular rod, the outer surfaces of the three hoses abut against the top of the support plate, four clamping plates are evenly fixedly installed on the top of the support plate, the hoses are disposed between two adjacent clamping plates, a spring is sleeved on the outer surface of the rectangular rod, and the two ends of the spring are respectively fixedly installed on the bottom of the support plate and the top of the rectangular tube.

[0008] The effect achieved by the above components is as follows: pressing the support plate downward causes the rectangular rod connected to the support plate to slide downward on the inner wall of the rectangular tube. The support plate will compress the spring, causing the spring to deform. After the hose is inserted between the two clamping plates, the spring will reset and drive the support plate to move upward until the hose is fully stretched. Then the support plate can support and limit the hose.

[0009] Preferably, a card block is fixedly installed on the top of the two adjacent card plates on the side closest to each other. The vertical cross-section of the card block is triangular, and the card block is made of rubber.

[0010] The effect achieved by the above components is as follows: by setting the locking blocks with the top of the locking blocks being beveled, after the hose is inserted between the two locking plates, it is easy to squeeze the two locking blocks through the hose, causing the locking blocks to deform and the hose to detach from the two locking blocks. At this time, the bottom of the locking blocks can limit the hose, which helps to prevent the hose from easily detaching from the locking plates, thereby making the support for the hose more stable.

[0011] Preferably, a bolt is threaded into the inner wall of one side of the rectangular tube.

[0012] The effect achieved by the above components is as follows: by rotating the bolt, one end of the bolt abuts against one end of the rectangular rod, the bolt can fix the rectangular rod and the rectangular tube, thereby fixing the height of the support plate and preventing the rectangular rod from shifting and causing the hose to lose support.

[0013] Preferably, a soft rubber strip is adhered to the inner wall of one side of the rectangular rod, and the bolt is located on one side of the soft rubber strip.

[0014] The effect achieved by the above components is that by setting up soft rubber strips, one side of the rectangular rod abuts against one end of the bolt, which increases the friction between the bolt and the rectangular rod, making the bolt more secure in fixing the rectangular rod and the rectangular tube.

[0015] Preferably, the disassembly and assembly assembly includes two circular hole blocks, one side of which is symmetrically fixedly installed on both sides of the bottom of the rectangular tube. Threaded pins are inserted into the inner wall of the circular hole blocks, and the two threaded pins are symmetrically fixedly installed on the top of the extension plate. Nuts are threadedly connected to the outer surface of the threaded pins.

[0016] The effect achieved by the above components is as follows: when both threaded pins are inserted into the inner wall of the circular hole block and the nut is rotated, the nut presses against the circular hole block, so that one side of the circular hole block fully abuts against the top of the extension plate, thus fixing the rectangular tube and the extension plate. At the same time, the rectangular tube can be disassembled, which facilitates the individual maintenance and replacement of the support device.

[0017] Preferably, a rubber pad is fixedly installed on one side of the nut, and the outer surface of the threaded pin is slidably inserted into the inner wall of the rubber pad.

[0018] The effect achieved by the above components is that by setting the rubber pad, the friction between the nut and the round hole block can be increased, making the nut less likely to loosen.

[0019] Preferably, U-shaped blocks are symmetrically fixedly installed on the top of the extension plate, and the outer surface of the circular hole block is inserted into the inner wall of the two U-shaped blocks.

[0020] The effect achieved by the above components is that by setting two U-shaped blocks, the round hole block can be quickly positioned, and the U-shaped blocks can fix the round hole block more firmly.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, a rectangular rod is provided that can slide on the inner wall of the rectangular tube. This allows the height of the rectangular rod to be adjusted according to the actual length of the hose. When the top of the rectangular rod comes into contact with the hose, the hose is fully stretched, which supports and limits the hose. This helps prevent the hose from hanging down onto the steel pipe and obstructing the movement of the permanent magnet wheel of the gas cutting machine, thus facilitating the normal operation of the seamless steel pipe gas cutting machine.

[0028] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a seamless steel pipe gas cutting machine, including a gas cutting machine body 1. Permanent magnet wheels 2 are rotatably installed at the four corners of the bottom of the gas cutting machine body. The permanent magnet wheels 2 are made of permanent magnet material, ensuring that the gas cutting machine will not detach from the steel pipe when moved. Three flexible hoses 3 are provided on one side of the top of the gas cutting machine body 1; generally, two are used to deliver high-pressure oxygen flow, and the other is used to deliver combustible gas. A common cutting torch head 4 is installed at one end of each of the three flexible hoses 3. An electric telescopic rod 5 is installed on one side of the gas cutting machine body 1. One end of the electric telescopic rod 5 is fixedly installed on the outer surface of the cutting torch head 4. The electric telescopic rod 5 can adjust the cutting torch head 4 according to the outer diameter of the steel pipe and actual needs. The positions are adjusted and fixed accordingly. Support devices 6 are provided on the outer surfaces of the three hoses 3. The support devices 6 support and limit the three hoses 3 by setting a rectangular rod 63 that can extend and retract in the rectangular tube 62. By setting the rectangular rod 63, the rectangular rod 63 can slide on the inner wall of the rectangular tube 62, so that the height of the rectangular rod 63 can be adjusted according to the actual length of the hose 3. When the top of the rectangular rod 63 abuts against the hose 3, the hose 3 is fully stretched, which can support and limit the hose 3. This helps to prevent the hose 3 from hanging on the steel pipe and obstructing the movement of the permanent magnet wheel 2 of the gas cutting machine, and facilitates the normal operation of the seamless steel pipe gas cutting machine.

[0029] Reference Figures 2-4As shown, the support device 6 includes an extension plate 61, a rectangular tube 62 is provided on the top of the extension plate 61, a disassembly assembly 7 is provided between the rectangular tube 62 and the extension plate 61, a rectangular rod 63 is slidably installed on the inner wall of the rectangular tube 62, a support plate 64 is fixedly installed on the top of the rectangular rod 63, the outer surfaces of the three flexible hoses 3 all abut against the top of the support plate 64, four clamping plates 65 are evenly fixedly installed on the top of the support plate 64, the flexible hoses 3 are placed between two adjacent clamping plates 65, a spring 66 is sleeved on the outer surface of the rectangular rod 63, the two ends of the spring 66 are respectively fixedly installed on the bottom of the support plate 64 and the top of the rectangular tube 62, when the support plate 64 is pressed downward, the rectangular rod 63 connected to the support plate 64 slides downward on the inner wall of the rectangular tube 62, the support plate 64 will compress the spring 66, causing the spring 66 to... After the hose 3 is inserted between the two clamping plates 65, the spring 66 will reset and drive the support plate 64 to move upward until the hose 3 is fully stretched. Then the support plate 64 can support and limit the hose 3. The top of the two adjacent clamping plates 65 is fixedly installed with a clamping block 67. The vertical cross section of the clamping block 67 is triangular and made of rubber. By setting the clamping block 67, the top of the clamping block 67 is inclined. After the hose 3 is inserted between the two clamping plates 65, it is easy for the hose 3 to squeeze the two clamping blocks 67 and deform the clamping blocks 67 until the hose 3 is separated from the two clamping blocks 67. At this time, the bottom of the clamping block 67 can limit the hose 3, which helps to prevent the hose 3 from easily separating from the clamping plate 65, thus making the support of the hose 3 more stable.

[0030] Reference Figure 2 and Figure 3 As shown, a bolt 68 is threaded into the inner wall of one side of the rectangular tube 62. By rotating the bolt 68, one end of the bolt 68 abuts against one end of the rectangular rod 63, thus fixing the rectangular rod 63 and the rectangular tube 62 together. This also helps to fix the height of the support plate 64, preventing the rectangular rod 63 from shifting and causing the hose 3 to lose support. A soft rubber strip 69 is adhered to the inner wall of one side of the rectangular rod 63. The bolt 68 is positioned on one side of the soft rubber strip 69. By setting the soft rubber strip 69, one side of the rectangular rod 63 abuts against one side of the bolt 68, increasing the friction between the bolt 68 and the rectangular rod 63, making the fixation between the rectangular rod 63 and the rectangular tube 62 by the bolt 68 more secure.

[0031] Reference Figure 2 and Figure 4As shown, the disassembly and assembly assembly 7 includes two round hole blocks 71. One side of each round hole block 71 is symmetrically fixedly installed on both sides of the bottom of the rectangular tube 62. Threaded pins 72 are inserted into the inner wall of the round hole block 71. The two threaded pins 72 are symmetrically fixedly installed on the top of the extension plate 61. Nuts 73 are threadedly connected to the outer surface of the threaded pins 72. When both threaded pins 72 are inserted into the inner wall of the round hole block 71 and the nuts 73 are rotated, the nuts 73 press against the round hole block 71, so that one side of the round hole block 71 fully abuts against the top of the extension plate 61. This can fix the rectangular tube 62 and the extension plate 61, and at the same time make the rectangular tube 62 detachable, thereby facilitating the individual maintenance and replacement of the support device 6.

[0032] Reference Figure 2 and Figure 4 As shown, a rubber pad 74 is fixedly installed on one side of the nut 73, and the outer surface of the threaded pin 72 is slidably inserted into the inner wall of the rubber pad 74. By setting the rubber pad 74, the friction between the nut 73 and the round hole block 71 can be increased, making the nut 73 less likely to loosen. U-shaped blocks 75 are symmetrically fixedly installed on the top of the extension plate 61, and the outer surface of the round hole block 71 is inserted into the inner wall of the two U-shaped blocks 75. By setting the two U-shaped blocks 75, the round hole block 71 can be quickly positioned, and the U-shaped blocks 75 can fix the round hole block 71 more firmly.

[0033] Working principle: The support plate 64 is pressed downwards, causing the rectangular rod 63 connected to it to slide downwards along the inner wall of the rectangular cylinder 62. The support plate 64 compresses the spring 66, causing it to deform. The hose 3 is then inserted between the two clamping plates 65 and pushed downwards, causing it to press against the two clamping blocks 67, deforming them until the hose 3 detaches from them. At this point, the bottom of the clamping blocks 67 again limits the hose 3, preventing it from easily detaching from the clamping plates 65. Removing the pressure on the support plate 64 causes the spring 66 to reset, moving the support plate 64 upwards until the hose 3 is fully stretched. Rotate bolt 68 so that one end of bolt 68 abuts against the rubber strip on one side of rectangular rod 63. Bolt 68 can fix the rectangular rod 63 and rectangular tube 62, thereby fixing the height of support plate 64. Support plate 64 can support and limit hose 3, which helps prevent hose 3 from drooping off the steel pipe. Insert round hole block 71 into the inner wall of two U-shaped blocks 75 and insert two threaded pins 72 into the inner wall of round hole block 71. Rotate nut 73 so that rubber pad 74 on one side of nut 73 squeezes round hole block 71, so that one side of round hole block 71 fully abuts against the top of extension plate 61, thereby fixing rectangular tube 62 and extension plate 61.
