[0002] As an important equipment for continuous casting in the process of steel smelting, the ladle is a container for holding, transporting and refining molten steel outside the furnace from steel tapping to pouring. It can perform deoxidation and alloying operations to calm the molten steel in order to adjust the temperature of the molten steel, make the composition uniform, and make the non-metallic inclusions in the molten steel float. At the same time, the flow rate of molten steel can be controlled during the casting process. The ladle consists of a barrel body, an inner lining, a water inlet opening and closing device, and a breathable brick. After a long period of use, the working layer of the ladle lining is affected by high temperature for a long time and is prone to damage. It needs regular maintenance, and the damaged prefabricated blocks of the working layer of the ladle lining need to be dismantled and repaired. Due to the large size of the ladle, when dismantling the prefabricated blocks at a higher position, the staff needs to board the lifting platform device, control the lifting platform to a certain height, and then dismantle and repair the prefabricated blocks of the working layer of the ladle lining.

[0020] 2. The present invention controls the moving crawler to move the installation base to the surface of the working layer of the ladle lining. After the staff climbs onto the top of the working base, the adjusting motor is controlled to rotate, and the two-way screw is controlled to rotate synchronously under the mutual engagement of the two sets of bevel gears, so that the moving seats on both sides of the two-way screw move in opposite directions on the surface of the limiting slide bar, driving the lifting fork frame to start shrinking and deforming, and lifting the work table, so that the staff can move the working layer of the ladle lining to a suitable height as the work table moves up, and the prefabricated blocks at different heights inside the working layer of the ladle lining can be dismantled and repaired.

[0035] As a further solution of the present invention, side panels 101 are symmetrically fixedly installed on both sides of the top of the mounting base 1, a bidirectional screw 102 is rotatably installed between the two groups of side panels 101, an adjusting motor 104 is fixedly installed on one side of one group of side panels 101, and a bevel gear 103 is fixedly installed on the output end of the adjusting motor 104 and the end of the bidirectional screw 102 close to the adjusting motor 104, respectively, and the two groups of bevel gears 103 are meshed with each other, and limited sliding rods 105 are symmetrically fixedly installed on both sides of the bidirectional screw 102 between the two groups of side panels 101, and a moving seat 106 is symmetrically slidably installed on the surfaces of both sides of the bidirectional screw 102 and the two groups of limited sliding rods 105; the adjusting motor 104 is controlled to move Rotate, thereby driving two sets of mutually meshing bevel gears 103 to rotate synchronously, so that the bidirectional screw 102 starts to rotate, and controls the moving seats 106 on the two side surfaces of the bidirectional screw 102 to move in opposite directions. The two ends of the bottom of the lifting fork frame 3 are rotatably connected to the side plates 101 and the moving seats 106 respectively. When the moving seats 106 are close to the side plates 101, the bottom ends of the lifting fork frame 3 are driven to approach each other, so that the lifting fork frame 3 contracts and extends, driving the lifting fork frame 3 to move, thereby facilitating the control of the height of the workbench 5 on the top of the lifting fork frame 3 at the top of the mounting base 1, so that the staff standing on the top of the workbench 5 can dismantle and repair the prefabricated blocks at different heights of the working layer of the ladle lining.

[0036] As a further solution of the present invention, a material discharge trough 501 is provided on one side of the workbench 5, and a material discharge plate 502 is rotatably installed on one side of the bottom of the workbench 5, and the material discharge plate 502 is located below the material discharge trough 501. A slide plate 503 is slidably installed on one side of the material discharge plate 502. The interior of the material discharge plate 502 is hollow, so that the slide plate 503 can slide inside the material discharge plate 502, so that the slide plate 503 can be pulled out from the inside of the material discharge plate 502, and the slide plate 503 is away from the surface and the side of the material discharge plate 502. The bottom surface is symmetrically fixed with a rubber clamping pad 504, and a pad 505 is fixedly installed at one end of the slide plate 503 away from the blanking plate 502; guide plates 506 are symmetrically fixedly installed on both sides of the top of the blanking plate 502; the pad 505 is pulled to pull the slide plate 503 out from the inside of the blanking plate 502, and the blanking plate 502 is controlled to tilt at the bottom of the workbench 5 until the pad 505 at one end of the slide plate 503 contacts the ground, so that the prefabricated block falling on the top of the blanking plate 502 slides toward the slide plate 503 and falls inside the steel plate. At the same time, when storing, the slide plate 503 is inserted into the blanking plate 502 so that the rubber clamping pad 504 is squeezed and deformed inside the blanking plate 502, so that the slide plate 503 is clamped and fixed inside the blanking plate 502, which is convenient for storing the slide plate 503 and the blanking plate 502.

[0037] As a further solution of the present invention, limiting slide grooves 508 are symmetrically arranged on both sides of the bottom of the workbench 5, and a support bar 507 is rotatably installed at one end of the guide plate 506 away from the discharge chute 501 through a rotating shaft or a pin shaft, and a connecting rod 510 is fixedly installed between the ends of the two groups of support bars 507 away from the guide plate 506 to ensure that the two groups of support bars 507 can move synchronously. At the same time, a convex column protrudes from one end of the support bar 507 close to the limiting slide groove 508 and is stuck in the limiting slide groove 508. The convex column slides in the limiting slide groove 508 to limit the support bar 507, and a convex column protrudes from the end of the support bar 507 away from the guide plate 506 The column is stuck in the limiting slide groove 508 and is slidably connected inside the limiting slide groove 508. A fixed plate 509 is fixedly installed on one side of the discharge chute 501 at the bottom of the workbench 5. An electric push rod 511 is symmetrically fixedly installed on one side of the fixed plate 509, and the end of the electric push rod 511 away from the fixed plate 509 is rotatably connected to the surface of the connecting rod 510. The electric push rod 511 is controlled to extend and retract, so that the connecting rod 510 at one end of the electric push rod 511 drives the support bar 507 to slide inside the limiting slide groove 508, thereby facilitating the control of the support bar 507 to lift the guide plate 506, and drive the discharge plate 502 to tilt to a suitable angle at the bottom of the workbench 5.

[0038] As a further solution of the present invention, a material unloading rack 6 is fixedly installed on one side of the top of the workbench 5, and a buffer plate 601 is symmetrically rotated and installed on the inner wall of the material unloading rack 6. An arc-shaped slide bar 602 is symmetrically fixedly installed on the bottom of the buffer plate 601. The arc-shaped slide bar 602 is slidably connected to the material unloading rack 6. The arc-shaped slide bar 602 passes through the side of the material unloading rack 6. When the buffer plate 601 is pushed to flip, the arc-shaped slide bar 602 is driven to slide on the side of the material unloading rack 6. A buffer spring 604 is provided on the surface of the arc-shaped slide bar 602, and one end of the arc-shaped slide bar 602 away from the buffer plate 601 passes through the material unloading rack 6 and is fixedly installed with a connecting plate 603. The connecting plate 603 connects the two groups of arc-shaped slide bars 602, so that the two groups of arc-shaped slide bars 602 can slide synchronously on the side of the material unloading rack 6 when the buffer plate 601 is flipped. After the dismantled prefabricated block is put into the unloading rack 6, it falls on the top of the two groups of buffer plates 601. Under the action of gravity, the buffer plates 601 are pressed down and rotate inside the unloading rack 6, squeezing the buffer springs 604 to deform. After the prefabricated block passes between the two groups of buffer plates 601, the buffer plates 601 are lifted up and reset under the rebound action of the buffer springs 604. At the same time, the prefabricated block passing through the buffer plates 601 is buffered more smoothly and passes through the unloading trough 501 below the unloading rack 6 and falls on the top of the unloading plate 502.

[0039] During operation, the movable crawler 2 is controlled to drive the workbench 5 to move to the inner wall of the working layer of the ladle lining. After the staff climbs onto the top of the workbench 5, the movable seat 106 is controlled to drive the lifting fork frame 3 to move. After the workbench 5 is lifted to a suitable height, the unloading plate 502 is controlled to tilt and deflect at the bottom of the workbench 5, so that the slide plate 503 is close to the bottom of the ladle. After the staff removes the prefabricated blocks of the working layer of the ladle lining, the removed prefabricated blocks are put into the unloading rack 6. After being buffered by the two groups of buffer plates 601 inside the unloading rack 6, the prefabricated blocks fall on the top of the unloading plate 502, slide from the top of the unloading plate 502 to the slide plate 503 and fall on the bottom of the ladle, thereby preventing the prefabricated blocks from being directly dropped from the high workbench 5 and causing damage to the bottom of the ladle.

[0040] As a further solution of the present invention, a protective frame 7 is fixedly installed on the top of the workbench 5 on one side of the unloading rack 6, and the protective frame 7 includes a protective side frame 1 701, and a protective side frame 2 702 is rotatably installed on one side of the protective side frame 1 701. The protective side frame 2 702 is provided with two groups of rectangular grooves 703 at the edge of one side away from the protective side frame 1 701, and an installation slide groove 704 is provided at the top of the rectangular groove 703 and inside the protective side frame 2 702. An installation groove 705 is connected to one side of the installation slide groove 704. The installation groove 705 is located longitudinally inside the protective side frame 2 702, and a pull rod 706 is slidably installed inside the installation groove 705. The top of 706 passes through the protective side frame 702, and the bottom end is located at the bottom of the installation groove 705 and is installed with a limiting plate 707. The surface of the pull rod 706 located inside the installation groove 705 is provided with a fixed spring 708, and the bottom end of the fixed spring 708 is blocked by the limiting plate 707. The middle part of the installation groove 705 is stepped and narrowed, and the top of the fixed spring 708 is blocked by the stepped narrowing position; the surface of the pull rod 706 located at the top of the installation groove 705 is fixedly installed with a fixed column 709, and the fixed column 709 corresponds to the position of the installation slide groove 704, and the fixed column 709 is L-shaped and the end longitudinally passes through the installation slide groove 704 and extends to the inside of the rectangular slot 703. A protective side frame three 710 is fixedly installed on one side of the unloading rack 6 away from the protective side frame one 701, and two groups of rectangular blocks 711 are fixedly installed on one side of the protective side frame three 710, and the positions of the rectangular blocks 711 correspond to the rectangular slots 703, and the rectangular blocks 711 are provided with holes for accommodating the fixed clamping columns 709.

[0041] Pulling the pull rod 706 drives the limit plate 707 to slide inside the installation slot 705, squeezing the fixed spring 708 to deform, and at the same time causing the fixed clamping column 709 to move up and out of the rectangular clamping slot 703, rotating the protective side frame 2 702 and the protective side frame 3 710 to close, so that the rectangular clamping block 711 is clamped into the corresponding rectangular clamping slot 703; loosening the pull rod 706, under the rebound action of the fixed spring 708, the limit plate 707 is pressed down to the bottom of the installation slot 705, and at the same time driving the fixed clamping column 709 to move down and insert into the rectangular clamping block 711 inside the rectangular clamping slot 703, thereby clamping the protective side frame 2 702 on one side of the protective side frame 3 710.

[0042] After the rectangular clamping block 711 is clamped and fixed inside the corresponding rectangular clamping groove 703, and the protective side frame 2 702 and the protective side frame 3 710 are closed and clamped, the workers who have stepped onto the workbench 5 are blocked inside the protective frame 7, ensuring that the workers will not fall off the workbench 5 from a height when they dismantle and repair the prefabricated blocks of the working layer of the ladle lining on the top of the workbench 5.

[0043] A construction method for a ladle lining working layer prefabricated block repair processing device, the construction method comprising the following steps:

[0044] The two groups of moving crawlers 2 are controlled to drive the installation base 1 to move, until the installation base 1 is moved to the inner wall of the ladle lining working layer, the pull rod 706 is pulled upward to drive the fixed clamping column 709 to move up and disengage from the rectangular clamping block 711, and the protective side frame 2 702 is rotated away from the protective side frame 3 710, so that the staff can climb onto the top of the workbench 5. After the staff climbs onto the top of the workbench 5, the protective side frame 2 702 is rotated to be close to the protective side frame 3 710, so that the rectangular clamping block 711 is clamped into the corresponding rectangular clamping groove 703, and the pull rod 706 is released. Under the rebound action of the fixed spring 708, the limit plate 707 is pressed against the bottom of the installation groove 705, thereby driving the pull rod 706 to move downward so that the fixed clamping column 709 extends out of the installation slide groove 704 and is clamped into the rectangular clamping block 711 inside the rectangular clamping groove 703, and the protective side frame 2 702 and the rectangular clamping block 711 are closed and clamped;

[0045] The pad 505 is pushed to make the rubber card pad 504 be pulled out from the inside of the blanking plate 502, and the control regulating motor 104 starts to rotate. After the meshing transmission of the two sets of bevel gears 103, the bidirectional screw 102 is controlled to rotate, so that the two sets of moving seats 106 move in opposite directions on the surface of the limiting slide bar 105, so that the lifting fork frame 3 begins to shrink and extend, and the working table 5 is lifted to a certain height, which is convenient for removing the prefabricated blocks of different heights of the working layer of the ladle lining. At the same time, the electric push rod 511 is controlled to extend, and the connecting rod 510 is pushed away from the fixed plate 509, driving the support bar 507 to slide in the limiting slide groove 508, so that the blanking plate 502 is tilted and rotated at the bottom of the working table 5, until the blanking plate 502 is rotated and tilted at a certain angle at the bottom of the working table 5, and the slide plate 503 slides out from the inside of the blanking plate 502 until the pad 505 is tightly attached to the bottom of the ladle;

[0046] The prefabricated blocks in the working layer of the ladle lining are removed, and the removed prefabricated blocks are dropped from the top of the unloading rack 6. After the prefabricated blocks fall inside the unloading rack 6 and contact the buffer plate 601, the prefabricated blocks push the two groups of buffer plates 601 to rotate inside the unloading rack 6, so that the buffer spring 604 slides on the surface of the arc-shaped slide bar 602 until the distance between the two groups of buffer plates 601 increases to the point where the prefabricated blocks pass through, so that the prefabricated blocks pass through the unloading trough 501 and fall on the top of the unloading plate 502. Since the unloading plate 502 is inclined at a certain angle at the bottom of the working table 5, the prefabricated blocks falling on the top of the unloading plate 502 slide from the surface of the unloading plate 502 to the slide plate 503 until the prefabricated blocks fall on the bottom of the ladle, thereby preventing the prefabricated blocks from piling up on the top of the working table 5 or being directly thrown to the bottom of the ladle after being removed, causing harm to the staff behind the bottom of the ladle.
