Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flame cutting, and in particular relates to a protective structure for a steel structure flame cutting machine. Background Art
[0002] In the field of steel pipe processing, flame cutting machines, as one of the key cutting tools, play a vital role. Specifically, flame cutting machines utilize a mixture of fuel gas and oxygen, or gasoline and oxygen, to efficiently cut metal materials. However, when using traditional flame cutting machines to process steel pipes, a magnetic transmission mechanism is commonly used to achieve circular cutting of the steel pipe. To ensure that the transmission mechanism can smoothly circle the steel pipe and complete the entire cut, the end of the steel pipe to be cut is usually suspended in the air. However, this practice often causes the cut steel pipe section to fall due to loss of support. This not only poses a safety threat to the operator, but also, due to the cylindrical nature of the steel pipe, it is prone to rolling during the fall, potentially damaging surrounding production equipment and the completed steel pipe product. It also increases the complexity and burden of subsequent processing. In view of this, the present utility model designs a protective structure specifically for steel structure flame cutting machines. This structure is designed to effectively support and stabilize the cut steel pipe section, preventing it from accidentally falling due to loss of support, thereby significantly improving the safety and stability of the cutting operation and reducing potential safety hazards and unnecessary losses.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.
[0017] Example
[0018] See also Figure 1-2 The utility model provides the following technical solutions: A protective structure for a steel structure flame cutting machine, comprising a connecting assembly and a supporting assembly, wherein the connecting assembly comprises a telescopic rod 1, both ends of which are equipped with pipe holders, and the two pipe holders are arranged symmetrically to ensure the stability and balance of the structure. The supporting assembly is installed at the bottom of one of the pipe holders to ensure the stable support of the cut section of the steel pipe. The telescopic rod 1 consists of a fixed tube 2 and an extension rod 3. One end of the extension rod 3 extends into the interior of the fixed tube 2 and is tightly combined with the fixed tube 2 by a sliding connection, giving the telescopic rod 1 flexible adjustment capabilities. The pipe holder comprises an upper pressure plate 4 and a lower pressure plate 5. The upper pressure plate 4 is directly fixedly connected to the end of the telescopic rod 1, while the upper pressure plate 4 and the lower pressure plate 5 are fastened together by long rod bolts, which not only ensures the stability of the connection but also facilitates subsequent disassembly and maintenance. The upper pressure plates 4 of the two pipe holders are fixedly connected to the fixed tube 2 and the end of the extension rod 3, respectively, to enhance the integrity and stability of the entire protective structure.
[0019] In order to better fit the steel pipe body and ensure the fixing strength, in this embodiment, as a preferred technical solution of the present utility model, the upper pressing plate 4 and the lower pressing plate 5 are both arc-shaped structures.
[0020] In order to facilitate the adjustment of the height of the support assembly so as to adapt to the use of pipe fittings of different heights, in this embodiment, as a preferred technical solution of the utility model, the support assembly includes a top plate 6 and a bottom plate 7, and a cross frame 8 is symmetrically installed between the top plate 6 and the bottom plate 7. The upper and lower ends of the two cross frames 8 are movably connected to the top plate 6 and the bottom plate 7 respectively, and a connecting shaft 9 is installed between the two upper and lower movable connection points of the two cross frames 8. The two connecting shafts 9 are fixed with nut barrels 10 on the shaft body, and the internal thread of the nut barrel 10 is connected to the screw 11. The thread directions of the rod body at both ends of the screw 11 are opposite, and the threads inside the nut barrel 10 adapted thereto are also opposite.
[0021] In order to facilitate the adjustment of the length of the telescopic rod 1, in this embodiment, as a preferred technical solution of the present invention, the extension rod 3 is equipped with a handle 12, and the fixed tube 2 is provided with a makeshift groove 13 at the handle 12 of the extension rod 3, and the handle 12 is placed in the makeshift groove 13.
[0022] In order to facilitate pulling apart the cut pipes, in this embodiment, as a preferred technical solution of the present invention, casters 14 are evenly installed on the bottom of the lower pressing plate 5.
[0023] In summary, according to the technical solution of the present invention, in actual application, the two fixtures should first be firmly installed on both sides of the target cutting point. The specific steps are: place the upper pressure plate 4 and the lower pressure plate 5 accurately on the upper and lower sides of the pipe body, respectively, and then use long rod bolts to tightly fix them on the pipe body. Next, by rotating the screw 11, the two nut barrels 10 are driven to move toward each other by the rotational movement of the screw 11, thereby causing the two connecting shafts 9 to approach each other. This action will drive the two cross frames 8 to gradually retract until the casters 14 at the bottom of the base plate 7 abut against the foundation surface to ensure a firm fixation. After the flame cutting machine completes the cutting operation of the steel pipe, the user can pull the handle 12 so that the handle drives the extension rod 3 to extend a certain length from the inside of the fixed tube 2 to achieve the extension of the rod body and pull the cut pipe body apart. Finally, the cut pipe body can be removed from the fixture.
[0024] Finally, it should be noted that in the present invention, unless otherwise clearly stipulated and limited, terms such as "installation", "setting", "connection", "fixation", and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.
