Its surface is coated with lead powder and there is an opening in the middle. The ladle slide plate is mainly used to control the flow rate of the molten steel inside the ladle. And the ladle slide plate has a large mass. When hot repairing the large ladle, the slide plate needs to be replaced and tested before it can be put into use.

[0027] The following further illustrates the present utility model in conjunction with the attached drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited do not limit the present utility model.

[0028] Refer to Figure 1 - Figure 6 As shown, a ladle slide plate detection device of the present utility model includes a base 1, a ladle body 2 is fixedly connected to the top of the base 1, and a driving mechanism is provided on one side of the base 1; the driving mechanism includes a fixed seat 9 fixedly connected to the base 1, the fixed seat 9 is rotationally connected to a first rotating arm 10 through a pin shaft, one end of the first rotating arm 10 is rotationally connected to a second rotating arm 11 through a pin shaft, one end of the second rotating arm 11 is rotationally connected to a third rotating arm 12 through a pin shaft, one end of the third rotating arm 12 is fixedly connected to a protective shell 13, a lifting plate 26 is slidably connected to the inner wall of the protective shell 13, and a hydraulic cylinder 14 is installed on the top of the lifting plate 26.

[0029] During operation, when testing the skateboard, since the position of the skateboard is not fixed in the up-down, left-right, front-back directions, the installation position of the hydraulic cylinder 14 is also not fixed. To solve the problem of quickly installing the hydraulic cylinder 14, through the cooperation of the first rotating arm 10, the second rotating arm 11, and the third rotating arm 12, it can move back and forth, left and right in the horizontal direction, and the third rotating arm 12 drives the protective shell 13 and the hydraulic cylinder 14 to move, realizing the function of adjusting the movement of the hydraulic cylinder 14 back and forth, left and right. And when the hydraulic cylinder 14 is not working, by folding the first rotating arm 10, the second rotating arm 11, and the third rotating arm 12 in cooperation, it is stored, which facilitates the outflow of molten steel from the ladle body 2 and reduces damage to the hydraulic cylinder 14.

[0030] Furthermore, as Figure 5 shown, the bottom of the lifting plate 26 is rotatably connected to a reciprocating screw rod 27 through a bearing. The reciprocating screw rod 27 is threadedly connected to the bottom of the protective shell 13, and the bottom of the reciprocating screw rod 27 is fixedly connected to a driving rod 28.

[0031] During operation, when the hydraulic cylinder 14 may have different heights during installation and it is inconvenient to lift the hydraulic cylinder 14 inside the protective shell 13, the driving rod 28 needs to be rotated. By driving the driving rod 28, the reciprocating screw rod 27 is driven to rotate. During the rotation of the reciprocating screw rod 27 on the protective shell 13, it moves up and down. By the upward movement of the reciprocating screw rod 27, the lifting plate 26 is driven to move up and down, and the hydraulic cylinder 14 is driven to move up and down by the lifting plate 26, thereby realizing the function of adjusting the height of the hydraulic cylinder 14.

[0032] Furthermore, as Figure 4 shown, two fixing plates 22 are fixedly connected to the side wall of the protective shell 13 away from the third rotating arm 12. A bidirectional ball screw 23 is rotatably connected to the two fixing plates 22 through bearings. Two moving plates 21 are threadedly connected to the bidirectional ball screw 23, and the moving plates 21 are all slidable on the protective shell 13; one end of each moving plate 21 is fixedly connected to a clamping plate 20, and the two clamping plates 20 are symmetrically arranged on both sides of the hydraulic cylinder 14; a second motor 25 is fixedly connected to one of the fixing plates 22, and the output shaft of the second motor 25 is fixedly connected to the bidirectional ball screw 23.

[0033] During operation, to improve the stability of the hydraulic cylinder 14, the top of the hydraulic cylinder 14 needs to be fixed. By driving the second motor 25, the second motor 25 drives the bidirectional ball screw 23 to rotate through the output shaft. The moving plates 21 are driven to move towards the center by the bidirectional ball screw 23, and the clamping plates 20 are driven to move towards the center by the moving plates 21 until the clamping plates 20 clamp and fix the hydraulic cylinder 14.

[0034] Furthermore, as Figure 4As shown, the output end of the hydraulic cylinder 14 is fixedly connected with a mounting seat 15; a first motor 16 is fixedly connected to the top side wall of the mounting seat 15. The output shaft of the first motor 16 is rotatably connected to the mounting seat 15 through a bearing. The output shaft of the first motor 16 is fixedly connected with a rotating block 17, and a distance sensor 18 is fixedly connected to the top of the rotating block 17.

[0035] During operation, by turning on the first motor 16, when the first motor 16 rotates, it drives the rotating block 17 to rotate. The rotating block 17 drives the distance sensor 18 to rotate. When the distance sensor 18 rotates to the top of the rotating block 17, through the cooperation of the first rotating arm 10, the second rotating arm 11 and the third rotating arm 12, it drives the distance sensor 18 to detect the balance of the lower slide plate 6. If the value of the distance sensor 18 is within the error range, it is qualified; if the error value of the distance sensor 18 is relatively large, it is unqualified and needs to be reinstalled.

[0036] Furthermore, as Figure 2 shown, the bottom of the ladle body 2 includes a water inlet 3 installed on the seat brick. The bottom of the water inlet 3 is connected and fixedly connected with an upper slide plate 5; a lower slide plate 6 is arranged below the upper slide plate 5, and a water outlet 4 is connected and fixedly connected to the lower slide plate 6; an installation frame 7 is fixedly connected to the bottom of the ladle body 2. The upper slide plate 5 is installed on the installation frame 7. Two sliding frames 8 are arranged on both side walls of the lower slide plate 6, and the sliding frames 8 all slide on the installation frame 7.

[0037] During operation, the molten steel in the ladle body 2 flows out from the water inlet 3, passes through the sliding connection of the installation frame 7 and the sliding frames 8. The positions where the upper slide plate 5 and the lower slide plate 6 are staggered are different. When the water inlet 3 cooperates with the water outlet 4, it then flows out from the water outlet 4.

[0038] Furthermore, as Figure 5 and Figure 6 shown, a first clamping part 19 is fixedly connected to the side wall of the rotating block 17 far away from the distance sensor 18, and a second clamping part 29 is fixedly connected to the bottom of the lower slide plate 6. The first clamping part 19 cooperates with the second clamping part 29.

[0039] During operation, when the first motor 16 rotates, it drives the rotating block 17 to rotate. When the first clamping part 19 rotates to the top of the rotating block 17, through the cooperation of the first clamping part 19 and the second clamping part 29, the lower slide plate 6 and the hydraulic cylinder 14 are connected together, facilitating the driving of the sliding of the lower slide plate 6 by the hydraulic cylinder 14, thereby driving the lower slide plate 6 for detection.

[0040] Furthermore, as Figure 3 shown, a side plate 30 is fixedly connected to the side wall of the second rotating arm 11, and an electric push rod 31 is fixedly connected to the top of the side plate 30. The output end of the electric push rod 31 penetrates through the side plate 30 and is fixedly connected with a fixing block 32.

[0041] When working, when the first rotating arm 10, the second rotating arm 11, and the third rotating arm 12 are not working, they are retracted and folded. At this time, the electric push rod 31 is turned on, and the output end of the electric push rod 31 drives the fixed block 32 to move downward. When the fixed block 32 contacts the base 1, the movement stops. The electric push rod 31 provides a supporting force for the driving mechanism to maintain the stability of the driving mechanism.

[0042] Furthermore, as Figure 4 shown, two guide rods 24 are fixedly connected between the two fixing plates 22, and the moving plates 21 all slide on the guide rods 24.

[0043] When working, during the movement of the moving plate 21, the moving plate 21 slides on the guide rod 24, and the guide rod 24 limits the moving plate 21 in the horizontal direction.

[0044] Working principle: When testing the skateboard, since the position of the skateboard is not fixed in the up and down, left and right, front and back directions, and the installation position of the hydraulic cylinder 14 is also not fixed. To solve the problem of quickly installing the hydraulic cylinder 14, through the cooperation of the first rotating arm 10, the second rotating arm 11, and the third rotating arm 12, it can move back and forth, left and right in the horizontal direction, and the third rotating arm 12 drives the protective shell 13 and the hydraulic cylinder 14 to move, realizing the function of adjusting the front, back, left, and right movement of the hydraulic cylinder 14. And when the hydraulic cylinder 14 is not working, by folding the first rotating arm 10, the second rotating arm 11, and the third rotating arm 12 in cooperation, it is stored, which is convenient for the molten steel in the ladle body 2 to flow out and reduces damage to the hydraulic cylinder 14; when the hydraulic cylinder 14 may have different heights during installation and it is not convenient to lift the hydraulic cylinder 14 in the protective shell 13, the driving rod 28 needs to be rotated. The driving rod 28 drives the reciprocating lead screw 27 to rotate. During the rotation of the reciprocating lead screw 27 on the protective shell 13, it moves up and down. The upward movement of the reciprocating lead screw 27 drives the lifting plate 26 to move up and down, and the lifting plate 26 drives the hydraulic cylinder 14 to move up and down, thereby realizing the function of adjusting the height of the hydraulic cylinder 14;

[0045] To improve the stability of the hydraulic cylinder 14, the top of the hydraulic cylinder 14 needs to be fixed. By driving the second motor 25, the second motor 25 drives the bidirectional ball screw 23 to rotate through the output shaft. The bidirectional ball screw 23 drives the moving plate 21 to move towards the center. The moving plate 21 drives the clamping plate 20 to move towards the center until the clamping plate 20 clamps and fixes the hydraulic cylinder 14;

[0046] By turning on the first motor 16, when the first motor 16 rotates, it drives the rotating block 17 to rotate. The rotating block 17 drives the distance sensor 18 to rotate. When the distance sensor 18 rotates to the top of the rotating block 17, through the cooperation of the first rotating arm 10, the second rotating arm 11 and the third rotating arm 12, it drives the distance sensor 18 to detect the balance of the lower slide plate 6. If the value of the distance sensor 18 is within the error range, it is qualified. If the error of the value of the distance sensor 18 is large, it is unqualified and needs to be reinstalled. When the first motor 16 rotates, it drives the rotating block 17 to rotate. When the first clamping member 19 rotates to the top of the rotating block 17, through the cooperation of the first clamping member 19 and the second clamping member 29, the lower slide plate 6 and the hydraulic cylinder 14 are connected together, which is convenient for driving the sliding of the lower slide plate 6 through the hydraulic cylinder 14, so as to drive the lower slide plate 6 to conduct detection.

[0047] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
