[0002] Flame cutting machine is a kind of equipment that uses gas flame to cut metal materials into required shapes and sizes. Flame cutting machine mainly generates high-temperature flame by mixing and burning gas (such as acetylene, propane, etc.) and oxygen. In the continuous casting process, liquid steel is continuously cast into solid continuous casting billets through a series of devices such as crystallizers. When the continuous casting billet reaches a certain length or according to the pre-set cutting length instruction, the continuous casting machine flame cutting machine starts to work. It needs to be accurately positioned at the cutting position of the continuous casting billet. Flame cutting machine is generally composed of flame cutting head, gas supply system and slide rail.

[0003] Flame cutting head: Its structure is similar to that of a spray gun, with gas channels, oxygen channels and high-pressure oxygen cutting channels inside;

[0004] Gas supply system components: including gas cylinders and oxygen cylinders and corresponding pressure reducing devices and pipelines;

Example

[0026] like Figure 1 - Figure 6 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem of the inconvenience of using the existing device, and the overall idea is as follows:

[0027] In view of the problems existing in the prior art, the utility model provides a flame cutting device for a continuous casting machine with convenient operation, comprising a flame cutting machine 11 and a slide rail 12, wherein the two slide rails 12 are both located below the flame cutting machine 11, and a plurality of one-way wheel brackets 13 are fixedly installed at the lower end of the flame cutting machine 11, each one-way wheel bracket 13 is located at the four corners of the flame cutting machine 11, and a pulley 14 is rotatably installed between each one-way wheel bracket 13;

[0028] The upper ends of the two slide rails 12 are symmetrically provided with limiting structures;

[0029] The limiting structure includes a limiting plate 15, each limiting plate 15 is located on both sides of the pulley 14, a first fixing plate 18 is fixedly installed on the side walls of the two slide rails 12, a storage groove 19 is opened inside the two slide rails 12, and a screw rod 22 is rotatably installed inside the two storage grooves 19, and the two screw rods 22 are partially exposed outside the slide rails 12. The circumferential surfaces of the two screw rods 22 are threadedly installed with a transmission block 23, and the lower ends of the two transmission blocks 23 are fixedly installed with a second fixing plate 25, each one-way wheel bracket 13 is located above the limiting plate 15, and each limiting plate 15 is penetrated by a through groove 16. By placing the two slide rails 12 as a whole on the continuous casting machine , and fit one side of the first fixed plate 18 with the continuous casting machine installation area, then the staff can adjust the parallelism of the slide rail 12 to ensure that the angle of the slide rail 12 after installation is parallel to the cutting angle of the workpiece, and then the staff can insert a flat-blade screwdriver into the rotating head of the screw rod 22 exposed outside the slide rail 12 and rotate it, so that the screw rod 22 and the transmission block 23 are threadedly transmitted, thereby driving the transmission block 23 and the second fixed plate 25 to approach the side of the first fixed plate 18, so that the second fixed plate 25 can clamp the side wall of the continuous casting machine installation area, so that the slide rail 12 can be fixed as a whole on the continuous casting machine installation area, which is convenient for disassembly and maintenance.

[0030] A slider 17 is symmetrically fixedly installed at the lower end of each one-way wheel bracket 13, each pulley 14 is fitted with the surface of the slide rail 12, and each slider 17 is slidably installed inside the through groove 16. The limiting grooves 21 are symmetrically provided on the side walls of the two storage grooves 19. By providing the through grooves 16, when the staff limits the flame cutting machine 11 on the slide rail 12, the staff can align the slider 17 with the through groove 16 of the upper limit plate 15 on the slide rail 12 and insert it for sliding installation, thereby facilitating docking and improving convenience.

[0031] Limiting blocks 24 are symmetrically fixedly installed on the side walls of the two transmission blocks 23, and each limiting block 24 is slidably installed inside the limiting groove 21. The two second fixed plates 25 are partially exposed to the outside of the slide rail 12. A plurality of connecting rods 26 are fixedly installed between the two slide rails 12. A flame cutting head 27 is provided at the upper end of the flame cutting machine 11. By setting the limiting groove 21 and the limiting block 24, when the transmission block 23 drives the second fixed plate 25 to move, the second fixed plate 25 can drive the limiting block 24 to slide in the limiting groove 21, thereby further improving stability.

[0032] Working principle:

[0033] In the first step, when using, the staff can first place the two slide rails 12 as a whole on the continuous casting machine installation area that needs to be cut (the installation area is U-shaped), and then the staff can pull the slide rail 12 in the direction away from the first fixed plate 18, so that the first fixed plate 18 fits with the U-shaped side wall of one side of the continuous casting machine installation area, and then the staff can adjust the parallelism of the slide rail 12 to ensure that the angle of the slide rail 12 after installation is parallel to the cutting angle of the workpiece, and then the staff can insert a flat screwdriver into the rotating screw 22 exposed outside the slide rail 12 The screw rod 22 and the transmission block 23 are screwed together, and the transmission block 23 and the limit block 24 are driven to slide in the storage groove 19 and the limit groove 21 respectively, and then the second fixing plate 25 is pulled closer to the first fixing plate 18, so that the second fixing plate 25 can be clamped on the other side of the U-shaped side wall of the continuous casting machine installation area, so that the slide rail 12 can be fixed on the continuous casting machine installation area as a whole. If disassembly is required, the staff can reversely rotate the screw rod 22 so that the second fixing plate 25 no longer clamps the continuous casting machine installation area.

[0034] In the second step, the staff can then align the pulley 14 on the flame cutting machine 11 between the slide rails 12, and align the slider 17 with the through groove 16 to insert the slider 17 into the through groove 16, and then the pulley 14 can be naturally inserted between the slide rails 12, so that the flame cutting machine 11 is limited on the slide rails 12, and then the staff can adjust the cutting position of the flame cutting head 27, and then the staff can start the flame cutting machine 11 to complete the cutting of the workpiece.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
