[0027] When using a burner to burn through and expand the furnace eye, the existing burner cannot rotate, and the burner rod on the burner is difficult to expand the furnace eye from a preset direction and angle, resulting in a poor expansion effect.

[0028] The utility model proposes a burn-through device, comprising a movable base plate 10, a rotating support assembly 20, a support beam 30, a guide sleeve 40 and a cooling sleeve 50. The rotating support assembly 20 is installed on the movable base plate 10, and the rotating support assembly 20 can rotate in the horizontal direction relative to the movable base plate 10; the support beam 30 is installed on the rotating support assembly 20, and the support beam 30 can rotate in the vertical direction relative to the rotating support assembly 20; the guide sleeve 40 is connected to the lower side of the support beam 30, and the extension direction of the guide sleeve 40 is consistent with the extension direction of the support beam 30; the cooling sleeve 50 is connected to the lower side of the support beam 30, and the cooling sleeve 50 and the guide sleeve 40 are spaced apart along the extension direction of the support beam 30, and the cooling sleeve 50 and the guide sleeve 40 are used for allowing the burn-through rod 80 to pass through in sequence.

[0029] See also Figure 1 , Figure 2 and Figure 3The support beam 30 is installed on the movable bottom plate 10 through the rotating support assembly 20, and the guide sleeve 40 and the cooling sleeve 50 are both connected to the bottom of the support beam 30, so that when the burn-through rod 80 is inserted into the guide sleeve 40 and the cooling sleeve 50, the extension direction of the burn-through rod 80 is consistent with the extension direction of the support beam 30, and the burn-through rod 80 can rotate synchronously with the support beam 30. The working end of the burn-through rod 80 faces the furnace eye and extends outside the cooling sleeve 50, so that the furnace eye is burned through by the working end of the burn-through rod 80. A plurality of running wheels are arranged at the bottom of the movable bottom plate 10, and the movable bottom plate 10 can drive the support beam 30 and the burn-through rod 80 to move together. The rotating support assembly 20 can drive the support beam 30 to rotate in the horizontal direction while providing support for the support beam 30, and the support beam 30 can rotate in the vertical direction relative to the rotating support assembly 20, thereby driving the burn-through rod 80 to rotate in the horizontal direction and the vertical direction through the support beam 30 to adjust the working direction and angle of the burn-through rod 80. The cooling sleeve 50 is connected to one end of the support beam 30 close to the furnace eye to cool the working end of the burn-through rod 80.

[0030] The burn-through device proposed in the utility model provides support for the support beam 30 by installing a rotating support assembly 20 on the movable bottom plate 10. The movable bottom plate 10 can drive the support beam 30 to move. The rotating support assembly 20 enables the support beam 30 to rotate in the horizontal direction and the vertical direction. The burn-through rod 80 is supported and guided by connecting a guide sleeve 40 and a cooling sleeve 50 below the support beam 30, so that the burn-through rod 80 can move and rotate synchronously with the support beam 30, thereby facilitating the adjustment of the operating direction and angle of the burn-through rod 80, so that the burn-through rod 80 can expand the furnace eye from different directions and angles, thereby improving the expansion effect. The operating end of the burn-through rod 80 is cooled by the cooling sleeve 50 to prevent the burn-through rod 80 from overheating, thereby extending the service life of the burn-through rod 80.

[0031] In one embodiment, the cooling sleeve 50 includes a cylinder 51 and a cooling ring 52. The cooling ring 52 is arranged on one end of the cylinder 51 facing the guide sleeve 40. The cooling ring 52 includes an inner ring 521, an outer ring 522 and two side walls 523. The two side walls 523 are respectively connected to the inner ring 521 and the outer ring 522 on both sides along the axial direction, and the inner ring 521, the outer ring 522 and the two side walls 523 together enclose a cooling cavity for storing coolant.

[0032] See also Figure 4The extension direction of the cylinder 51 is consistent with the extension direction of the support beam 30. The cooling ring 52 is arranged at one end of the cylinder 51 facing the guide sleeve 40. The outer cylinder wall of the cylinder 51 and the outer ring 522 of the cooling ring 52 are both connected to the support beam 30. The inner cylinder wall of the cylinder 51 and the inner ring 521 of the cooling ring 52 can both circumferentially abut against the burn-through rod 80. The outer ring 522 and the inner ring 521 are arranged at intervals along the circumferential direction, and the outer ring 522 and the inner ring 521 are connected by two side walls 523. The inner ring 521, the outer ring 522 and the two side walls 523 enclose a closed cooling cavity. When the burn-through rod 80 abuts against the inner cylinder wall and the inner ring 521 of the cylinder 51, the coolant in the cooling cavity can cool the burn-through rod 80, thereby isolating the heat on the burn-through rod 80 and reducing the heat of the burn-through rod 80 from being transferred to the guide sleeve 40 and other structures on the burn-through device, so as to provide protection for the burn-through device.

[0033] In one embodiment, a liquid inlet and outlet 524 communicating with the cooling cavity is formed on the side wall 523 .

[0034] See also Figure 5 , the coolant can flow into or out of the cooling cavity through the inlet and outlet 524, thereby realizing the circulation of the coolant and improving the cooling efficiency of the coolant. It can be explained that the inlet and outlet 524 can be flexibly set according to the shape of the cooling ring 52. When the cooling ring 52 is disconnected to form the adjustment slit 53, the inlet and outlet 524 are opened on both sides of the side wall 523 along the adjustment slit 53, so that the coolant can fully flow through the cooling ring 52, thereby improving the cooling efficiency.

[0035] In one embodiment, the cooling sleeve 50 is circumferentially disconnected to form an adjustment gap 53, which axially penetrates the cylinder body 51 and the cooling ring 52. The cylinder wall of the cylinder body 51 is provided with two connecting ears 54 on both sides of the adjustment gap 53, each connecting ear 54 extends in a direction away from the cylinder body 51, and the two connecting ears 54 are connected by a plurality of adjusting members 55, each adjusting member 55 is used to adjust the distance between the two connecting ears 54.

[0036] Please continue reading Figure 4 and Figure 5 The cooling sleeve 50 is disconnected along its circumference, and an adjustment gap 53 is formed between the two ends of the cooling sleeve 50 along the circumference. The barrel 51 and the cooling ring 52 can both deform to a certain extent. The adjustment member 55 is used to adjust the spacing between the two connecting ears 54, so that the two connecting ears 54 drive the barrel 51 to deform, and the two ends of the barrel 51 along the circumference are close to or away from each other, and the barrel 51 drives the cooling ring 52 to deform synchronously, so that the inner wall of the barrel 51 and the inner ring 521 of the cooling ring 52 are both in contact with the burn-through rod 80, so that the cooling sleeve 50 can adapt to the burn-through rods 80 of different rod diameters. In one embodiment, the adjustment member 55 is an adjustment bolt.

[0037] In one embodiment, the rotating support assembly 20 includes a turntable 21, a bracket 22 and a hinge shaft 23. The turntable 21 is installed on the movable base plate 10 and can rotate in the horizontal direction relative to the movable base plate 10. The bottom of the bracket 22 is connected to the turntable 21. The bracket 22 is formed with an avoidance cavity for the burn-through rod 80 to pass through. The hinge shaft 23 is rotatably connected to the bracket 22. The support beam 30 is connected to the hinge shaft 23 and can rotate vertically around the hinge shaft 23.

[0038] It should be noted that the turntable 21 is horizontally mounted on the moving base plate 10 and can rotate in the horizontal direction relative to the moving base plate 10. The bottom of the bracket 22 is connected to the turntable 21, so that the bracket 22 can rotate synchronously with the rotation. The bracket 22 is formed with two side walls 523 extending upward. The two ends of the hinge shaft 23 are respectively connected to the two side walls 523. The hinge shaft 23 is horizontally arranged so that the hinge shaft 23 can rotate vertically relative to the bracket 22, and a avoidance cavity is formed between the two side walls 523. The support beam 30 is connected to the hinge shaft 23 so that the support beam 30 can rotate vertically relative to the hinge shaft 23, thereby realizing multi-directional rotation of the support beam 30 in the horizontal direction and in the vertical direction. By setting the rotating support assembly 20, it is convenient to adjust the direction and angle of the support beam 30, thereby facilitating the adjustment of the operating direction and angle of the burn-through rod 80 below the support beam 30.

[0039] In one embodiment, the support beam 30 includes a first support section and a second support section connected to each other, the hinge shaft 23 is located at the connection between the first support section and the second support section, the guide sleeve 40 is connected to the first support section, and the cooling sleeve 50 is connected to the end of the second support section facing away from the first support section.

[0040] It can be understood that the support beam 30 is divided into a first support section and a second support section by the connection position of the hinge shaft 23. The second support section is convenient for the burn-through rod 80 to extend to the furnace eye position. A handle is provided on the first support section. The direction of the first support section is adjusted by the handle to adjust the direction of the second support section, so as to maintain the balance of the support beam 30 during the direction adjustment process of the support beam 30.

[0041] In one embodiment, the burn-through device further includes a plurality of counterweights 60 , a clamping strip is provided on the first support section, the extension direction of the clamping strip is consistent with the extension direction of the support beam 30 , and each counterweight 60 is provided with a clamping slot for clamping with the clamping strip.

[0042] Furthermore, the counterweight block 60 is connected to the first support section by means of a card slot and a card strip, which facilitates the quick installation and removal of the counterweight block 60. By adjusting the number and connection position of the counterweight blocks 60 on the first support section, the center of gravity position of the support beam 30 can be quickly adjusted, which facilitates maintaining the balance of the support beam 30 and improving the stability of the support beam 30.

[0043] In one embodiment, there are multiple guide sleeves 40 , all of which are connected to the first support section, and the multiple guide sleeves 40 are spaced apart along the extension direction of the support beam 30 .

[0044] It is understandable that providing a plurality of guide sleeves 40 to guide the burn-through rod 80 can improve the guiding accuracy, help the burn-through rod 80 to operate more accurately along the preset direction, and provide more stable support for the burn-through rod 80. The plurality of guide sleeves 40 are all connected to the first support section, so that each guide sleeve 40 is as far away from the cooling sleeve 50 as possible, reducing the heat transferred from the burn-through rod 80 to the guide sleeve 40, so as to protect the guide sleeve 40. In one embodiment, the number of the guide sleeves 40 is two.

[0045] In one embodiment, the burn-through device further includes an elastic member 70 , and the elastic member 70 is connected between the moving base plate 10 and the guide sleeve 40 farthest from the cooling sleeve 50 .

[0046] It should be noted that when the support beam 30 rotates relative to the movable base plate 10, the elastic member 70 is correspondingly elastically deformed, and the elastic member 70 provides a pulling force to the guide sleeve 40, thereby limiting the rotation of the support beam 30 within a certain range, preventing the support beam 30 from rotating too much and causing the operating angle of the burn-through rod 80 to deviate too much, thereby protecting the burn-through rod 80. In addition, the elastic member 70 can provide a reset effect for the support beam 30.

[0047] In one embodiment, the extending direction of the movable base plate 10 is consistent with the extending direction of the support beam 30 , and the two ends of the movable base plate 10 along the extending direction are respectively connected to the rotating support assembly 20 and the elastic member 70 .

[0048] Furthermore, the rotating support assembly 20 and the elastic member 70 are respectively connected to the two ends of the movable base plate 10. When the support beam 30 rotates relative to the rotating support assembly 20, the displacement of the guide sleeve 40 connected to the elastic member 70 is the largest, and the elastic member 70 can effectively limit the rotation range of the support beam 30. In addition, the tension applied by the elastic member 70 to the guide sleeve 40 can balance a part of the torque during the rotation of the support beam 30, thereby helping to improve the stability of the support beam 30.

[0049] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
