Detailed implementation mode

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Embodiment 1

[0027] As Figures 1 to 3 shown, the preferred implementation mode of the continuous casting roll dismounting device of the present invention includes a base 1, a hydraulic rod 2, a support mechanism and a baffle 4. The hydraulic rod 2, the support mechanism and the baffle 4 are all sequentially installed on the base 1. The base 1 has a first step 11 and a second step 12. The first step 11 is higher than the second step 12. The hydraulic rod 2 is located on the first step 11. The support mechanism and the baffle 4 are both located on the second step 12, which is convenient for compensating the height difference of the hydraulic rod 2. The support mechanism is used to support the continuous casting roll 7 and adjust the height of the continuous casting roll 7 to align the center of the continuous casting roll 7 with the center of the hydraulic rod 2. The output rod of the hydraulic rod 2 extends into the continuous casting roll 7 located on the support mechanism to eject the spacer sleeve, bearing and shaft sleeve in the continuous casting roll 7. The baffle 4 is used to resist the continuous casting roll 7 to prevent the continuous casting roll 7 from moving laterally. An industrial control computer 5 is arranged on the base 1, and the industrial control computer 5 is used to control the hydraulic rod 2 and the support mechanism. A jack is fixed at the output end of the hydraulic rod 2, and the jack is detachably fixed on the hydraulic rod 2 and can be replaced according to different sizes of the continuous casting roll 7 to better eject the spacer sleeve, bearing and shaft sleeve.

[0028] Two slide rails 13 are arranged on the second step 12. The slide rails 13 are symmetrically arranged on the second step 12, and the center lines of the two slide rails 13 are on the same straight line as the center line of the hydraulic rod 2. In this way, it is convenient to quickly align the center lines when installing the support mechanism and the baffle 4 without lateral adjustment.

[0029] The support mechanism includes a V-shaped support base 31, a support plate 32, a base plate 33, a lifter 34, a positioning strip 35, a detection rod 36, a return spring 37, and a distance sensor 38. The base plate 33 is fixed to the base 1 by screws. The lifter 34 is installed on the base plate 33. The support plate 32 is installed on the lifter 34. The V-shaped support base 31 is installed on the support plate 32. The lifter 34 drives the support plate 32 to move up and down. The support plate 32 drives the V-shaped support base 31 to move up and down. The up and down movement of the V-shaped support base 31 drives the continuous casting roll 7 to move up and down. The lifter 34 uses a hydraulic cylinder, and in other embodiments, it can also be other lifting devices such as a cylinder. The V-shaped support base 31 is fixed and does not change its position due to continuous casting rolls 7 of different diameters. The V-shaped support base 31 has a movable space for accommodating the positioning strip 35. The positioning strip 35 is located within the movable space of the V-shaped support base 31. When the positioning strip 35 is not under force, the top surface of the positioning strip 35 is flush with the axis line of the output rod of the hydraulic rod 2, which facilitates calculating the distance between the axis line of the continuous casting roll 7 and the axis line of the output rod. The upper end of the detection rod 36 extends into the V-shaped support base 31 and is fixed to the positioning strip 35. The lower end of the detection rod 36 passes through the support plate 32 and the base plate 33 and extends into the base 1. The base 1 is provided with a receiving cavity. The lower end of the detection rod 36 extends into the receiving cavity. The distance sensor 38 is provided directly below the detection rod 36. The distance sensor 38 is used to detect the distance between itself and the detection rod 36. A feedback plate 362 is provided at the bottom of the detection rod 36. The feedback plate 362 is used to increase the feedback area to prevent the distance sensor 38 from missing detection. A retaining ring 361 is provided on the detection rod 36. The return spring 37 is sleeved on the detection rod 36. One end of the return spring 37 abuts against the retaining ring 361 of the detection rod 36, and the other end of the return spring 37 abuts against the support plate 32 to ensure that the detection rod 36 can return to its original position when not under force. Both the distance sensor 38 and the lifter 34 are electrically connected to the industrial control computer 5. The distance sensor 38 detects the height of the detection rod 36, that is, the distance a between the distance sensor 38 and the lower end face of the feedback plate 362 on the detection rod 36. The industrial control computer 5 subtracts the radius of the continuous casting roll 7 from the distance value to obtain a difference. This difference is the height that the lifter 34 needs to adjust. When the difference is negative, the lifter 34 needs to be lowered. When the difference is positive, the lifter 34 needs to be raised. If the difference is 0, no adjustment is required. Generally speaking, only when removing continuous casting rolls 7 of the same diameter is the difference 0. When replacing continuous casting rolls 7 of different diameters, the difference will inevitably change. It should be known that the radius of the continuous casting roll 7 is manually input into the industrial control computer 5, and the radius value needs to be changed when replacing the continuous casting roll 7.

[0030] The V-shaped support base 31 includes two inclined plates 311 and support rods 312 provided on the inclined plates 311. There are multiple support rods 312 to ensure that the inclined plates 311 can support the continuous casting roll 7. An activity opening 3111 is provided on each inclined plate 311, and the positioning strip 35 is located in the activity opening 3111. The activity opening 3111 is arranged in the height direction to ensure sufficient space for the positioning strip 35 to move. There is a spacing between the lower ends of the two inclined plates 311 to increase the spacing of the inclined plates 311.

[0031] The baffle 4 includes a vertical plate 41, a reinforcing plate 42 and a horizontal plate 43. The vertical plate 41 is fixed on the horizontal plate 43, and the reinforcing plate 42 is connected to both the vertical plate 41 and the horizontal plate 43. The reinforcing plate 42 is used to increase the strength of the vertical plate 41. A discharge opening 401 is provided on the vertical plate 41, facilitating the dropping of the spacer sleeve, bearing and shaft sleeve from the discharge opening 401 when they are ejected. A guiding plate 44 is also provided at the discharge opening 401, facilitating the guiding of the spacer sleeve, bearing and shaft sleeve so that they do not drop directly, being able to buffer the spacer sleeve, bearing and shaft sleeve to avoid damage.

[0032] When replacing the continuous casting roll 7, the continuous casting roll 7 is placed on the V-shaped support base 31. The distance sensor 38 detects the distance of the detection rod 36, and the industrial control computer 5 calculates the amount that the lifter 34 needs to lift or lower according to the detected value. The industrial control computer 5 controls the lifter 34 to perform corresponding lifting or lowering, so that the axis line of the continuous casting roll 7 is aligned with the axis of the hydraulic rod 2; at the same time, the ejector rod on the hydraulic rod 2 and the baffle 4 are replaced with appropriate sizes. In this way, the continuous casting roll 7 can be disassembled. Replacing the baffle 4 is mainly to replace the discharge opening 401 of different sizes. When it needs to be disassembled, the hydraulic cylinder extends, and the ejector rod on the hydraulic rod 2 penetrates into the continuous casting roll 7 to eject the spacer sleeve, bearing and shaft sleeve, thus completing the disassembly.

[0033] Embodiment 2

[0034] As Figure 5 and Figure 6 shown, compared with Embodiment 1, this embodiment further includes a displacement hydraulic cylinder 6.

[0035] The displacement hydraulic cylinder 6 is connected to the baffle 4, and the displacement hydraulic cylinder 6 is installed on the base 1. The displacement hydraulic cylinder 6 drives the baffle 4 to move to adapt to continuous casting rolls 7 of different lengths. To ensure the stability of the position of the baffle 4, a locking member 61 is further provided on the baffle 4. The locking member 61 is a screw, and the base 1 is not provided with screw holes, that is, the corresponding position is flat, so that the baffle 4 can be fixed in position by rotating the locking member 61.

[0036] Embodiment 3

[0037] As Figures 7 to 9As shown in the figure, in this embodiment, the structure of the baffle 4 and the connection relationship between the baffle 4 and the guiding plate 44 are different from those in the first and second embodiments.

[0038] The vertical plate 41 includes a fixed plate 411 and a movable plate 412. The movable plate 412 is inserted into the fixed plate 411, and the guiding plate 44 is fixed on the horizontal plate 43. Specifically, slots are provided on the fixed plate 411, and protrusions adapted to the slots are provided on both sides of the movable plate 412. The protrusions are inserted into the slots. By setting the vertical plate 41 as a split structure, it is more convenient to replace the size of the discharge opening 401, without the need to disassemble and fix the horizontal plate 43, reducing the workload during replacement. The lower end of the guiding plate 44 is fixed on the horizontal plate 43, and a support column 441 is further provided on the guiding plate 44. The lower end of the support column 441 abuts against the horizontal plate 43 to provide support for the guiding plate 44.

[0039] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structures made by using the content of the specification and drawings of the present invention, directly or indirectly applied in other related technical fields, are equally within the patent protection scope of the present invention.
