Description

Technical Field

[0001] The utility model belongs to the technical field of surfacing welding machines, and in particular relates to a continuous casting roller repair surfacing welding machine. Background Art

[0002] During long-term use, the surface of the coupling roller will appear reduced in size and irregular in shape due to wear, corrosion and other reasons. The cladding machine can add metal materials to the surface of the coupling roller by cladding to restore it to its original size and shape, ensuring that it can be installed and used normally. For example, when the diameter of the coupling roller becomes smaller due to wear, cladding can accumulate a certain thickness of wear-resistant material on its surface to restore its diameter to the design requirements.

[0003] After searching, in the relevant field, the patent "A continuous casting machine roller surfacing device" with announcement number CN221582307U uses a roller frame to support the continuous casting roller, but the lifting distance of the roller frame is fixed and cannot be adjusted. In practical applications, this device can only play an auxiliary role for continuous casting rollers of specific sizes, and has poor adaptability. It cannot meet the use requirements of continuous casting rollers of different diameters and sizes, and it is difficult to adapt to existing repair requirements. For this reason, another continuous casting roller repair surfacing machine is provided to solve the above technical problems. Utility Model Content

The utility model provides a continuous casting roller repair surfacing machine, which slides and installs two brackets with auxiliary wheels in a ground frame, and a spacing adjustment device is provided between the brackets. When assisting the lifting of coupling rollers of different sizes, the spacing adjustment device can synchronously drive the two brackets to move inward or outward, thereby changing the lifting position of the auxiliary wheels to adapt to the auxiliary operation requirements of coupling rollers of different sizes. This design makes the surfacing machine more adaptable, and can easily meet the current needs of welding machines for repair operations of continuous casting rollers of different sizes, and effectively solves the problems of the roller frame structure used in the surfacing device in the prior art being single, poor adaptability, unable to meet the use requirements of continuous casting rollers of different diameters, and difficult to adapt to the existing repair requirements. Its specific technical scheme is as follows:

[0005] A continuous casting roller repair surfacing welding machine comprises a ground frame, in which a walking and lifting welding equipment body is installed, and two brackets are slidably installed in the ground frame, and the brackets are located below the walking and lifting welding equipment body.

[0006] In the above technical scheme, the spacing adjustment device includes a stepper motor and a forward and reverse bidirectional screw, the stepper motor is fixedly mounted on the left surface of the grounding frame, and the output end of the stepper motor is fixedly connected to the left end of the forward and reverse bidirectional screw, the forward and reverse bidirectional screw is rotatably mounted in the grounding frame, and the outer surface of the forward and reverse bidirectional screw is threadedly mounted with two double-end adapter blocks, the front and rear ends of the double-end adapter block are rotatably mounted with hinged rods, the end of the hinged rod away from the double-end adapter block is rotatably connected with a U-shaped connecting block, the U-shaped connecting block is fixedly connected to the adjacent bracket, a directional rod is fixedly mounted in the grounding frame, and the directional rod is slidably connected to the double-end adapter block.

[0007] In the above technical solution, a plurality of load-bearing ground wheels are fixedly mounted on the lower surface of the bracket.

[0010] In the above technical solution, the locking member is a locking bolt, the locking bolt is threadedly connected to the L-shaped slider, and one end of the locking bolt close to the bracket is in contact with the outer surface of the bracket.

[0011] Compared with the prior art, the continuous casting roller repair surfacing machine of the utility model has the following beneficial effects:

[0012] The utility model slides two brackets with auxiliary wheels in the ground frame, and sets a spacing adjustment device between the brackets. When assisting the lifting of coupling rollers of different sizes, the spacing adjustment device can synchronously drive the two brackets to move inward or outward, thereby changing the lifting position of the auxiliary wheels to meet the auxiliary operation requirements of coupling rollers of different sizes. This design makes the cladding machine more adaptable and can easily meet the current requirements of welding machines for repairing continuous casting rollers of different sizes.

[0013] The utility model sets a plurality of auxiliary wheels on the bracket for sliding movement, and sets locking parts between the auxiliary wheels and the bracket.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In this embodiment, the front, rear, left, right, top and bottom are represented by Figure 1 Describes the datum surface. Figure 1-Figure 7 , the utility model provides a technical solution:

[0024] A continuous casting roller repair surfacing welding machine comprises a ground frame 1, a walking and lifting welding equipment body 2 is installed in the ground frame 1, two brackets 3 are slidably installed in the ground frame 1, the brackets 3 are located below the walking and lifting welding equipment body 2, a plurality of auxiliary wheels 4 are slidably installed on the upper surfaces of the brackets 3, locking pieces are arranged between the auxiliary wheels 4 and the brackets 3, and a spacing adjustment device 5 is installed between the two brackets 3;

[0025] It should be noted that, combined with Figure 4 and Figure 5As shown, the spacing adjustment device 5 includes a stepper motor 51 and a forward and reverse bidirectional screw 52. The stepper motor 51 is fixedly mounted on the left surface of the ground frame 1, and the output end of the stepper motor 51 is fixedly connected to the left end of the forward and reverse bidirectional screw 52. The forward and reverse bidirectional screw 52 is rotatably mounted in the ground frame 1, and the outer surface of the forward and reverse bidirectional screw 52 is screwed with two double-end adapter blocks 53 (the two double-end adapter blocks 53 are as shown in FIG. Figure 4 As shown, the outer surface of the forward and reverse bidirectional screw 52 is symmetrically installed with the middle part of the forward and reverse bidirectional screw 52 as the reference), the front and rear ends of the double-end transfer block 53 are rotatably installed with hinge rods 54, and one end of the hinge rod 54 away from the double-end transfer block 53 is rotatably connected with a U-shaped connection block 55, and the U-shaped connection block 55 is fixedly connected to the adjacent bracket 3, and a directional rod 56 is fixedly installed in the grounding frame 1, and the directional rod 56 is slidably connected to the double-end transfer block 53;

[0026] When it is necessary to adjust the distance between the two brackets 3 and adjust the auxiliary wheel 4 to a suitable lifting position for the continuous casting roller, start the stepper motor 51, and the stepper motor 51 drives the forward and reverse bidirectional screw 52 to rotate forward or reversely to drive the two double-end adapter blocks 53 to move synchronously inward or outward. When the two double-end adapter blocks 53 move synchronously inward, the two brackets 3 can be pulled inward by the hinge rod 54 to narrow the distance, and the position of the auxiliary wheel 4 can be changed to lift the coupling roller with a smaller diameter. Conversely, when the two double-end adapter blocks 53 move synchronously outward, the two brackets 3 can be pushed outward by the hinge rod 54 to increase the distance, and the position of the auxiliary wheel 4 can be changed to lift the coupling roller with a larger diameter. Compared with the prior art, the present cladding machine can adapt to the auxiliary operation requirements of coupling rollers of different sizes, making the present cladding machine more adaptable and able to easily meet the current needs of welding machines for repair operations of continuous casting rollers of different sizes.

[0027] In addition, in order to enhance the load-bearing capacity of the bracket 3 and prevent deformation caused by the weight during the lifting of the coupling roller, thereby affecting the sliding connection effect between the bracket 3 and the grounding frame 1, as shown in FIG. Figure 2 or Figure 3 As shown, a plurality of load-bearing wheels 31 are fixedly mounted on the lower surface of the bracket 3 , and the load-bearing wheels 31 can be used to support the bracket 3 , thereby enhancing the load-bearing capacity of the bracket 3 .

[0028] Combination Figure 3 and Figure 1 As shown, C-shaped blocks 33 are fixedly installed at both left and right ends of the bracket 3, and the C-shaped blocks 33 are slidably connected to the grounding frame 1, and the bracket 3 is slidably connected to the grounding frame 1 through the C-shaped blocks 33.

[0029] Specifically, if Figure 3 As shown, the front surface of the bracket 3 is provided with a slide groove 32, Figure 6and Figure 3 As shown, the front and rear surfaces of the auxiliary wheel 4 are fixed with L-shaped sliders 41 by bolts, and the L-shaped sliders 41 are slidably installed in the slide groove 32 to achieve a sliding connection between the auxiliary wheel 4 and the bracket 3, as shown in FIG. Figure 3 As shown, the locking member is a locking bolt 42, and the locking bolt 42 is threadedly connected to the L-shaped slider 41. After tightening the locking bolt 42, one end of the locking bolt 42 close to the bracket 3 fits with the outer surface of the bracket 3 to fix the position of the auxiliary wheel 4;

[0030] For shorter continuous casting rollers, the position of the auxiliary wheel 4 on the bracket 3 can be slidably adjusted by loosening the locking bolts 42 at the corresponding positions to ensure uniform support of the coupling rollers, thereby maintaining the balance of the support and effectively preventing the problem of unstable placement of the continuous casting rollers due to local uneven force. Excellent stability is crucial to improving the quality of repair. It reduces the repair error caused by the shaking of the continuous casting rollers and ensures that the repaired continuous casting rollers can meet high-precision usage standards.
