Description

Technical Field

[0001] The utility model relates to the technical field of crystallizer width limiting devices, and more specifically, the utility model relates to a crystallizer width limiting device for steel mills that is easy to adjust. Background Technique

[0002] In the current steel industry, the on-line width adjustment technology of crystallizers has been fully applied. This technology enables the production of billets with different cross-sectional sizes without stopping the continuous casting machine, so that production can be organized more flexibly according to orders, improving the operation rate of the continuous casting machine and increasing production capacity. At present, there are various driving methods for on-line width adjustment, and the hydraulic width adjustment method is the most widely used. The hydraulic width adjustment is powered by an independent hydraulic station, relying on a hydraulic servo valve to control the speed and position of the piston rod of the width adjustment hydraulic cylinder, and adjusting the opening of the servo valve through the feedback signal of the position sensor, so as to achieve closed-loop control of speed and displacement.

[0003] Among them, the patent with the patent application number CN201720727113.0 discloses a variable-frequency hydraulic width adjustment device for a crystallizer. A variable-frequency hydraulic width adjustment device for a crystallizer, including a crystallizer, is characterized in that: it also includes a motor, a frequency converter, a controller, a hydraulic pump, an oil tank, a servo valve group, a hydraulic cylinder and a displacement sensor. The output shaft of the motor is connected to the hydraulic pump, the oil outlet of the hydraulic pump is connected to the cylinder body of each hydraulic cylinder through a pipeline, a servo valve group is provided at the oil inlet of each cylinder body, a displacement sensor is provided on the piston rod of the hydraulic cylinder, and the moving end of the piston rod is connected to the movable plate on the same side;

[0004] When this structure is in use, by rotating the movable plate relative to the horizontal plane, the included angle between the movable plate and the horizontal plane can be adjusted within the range of 15° to 90°, so as to adjust the shape of the crystallizer. When the piston rods of the left and right hydraulic cylinders move towards or away from each other, the movable plate can be translated relative to the fixed plate, so as to adjust the size of the crystallizer. However, its installation position is fixed, which results in limitations in width adjustment. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a crystallizer width limiting device for steel mills that is easy to adjust, aiming to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A crystallizer width limiting device for steel mills that is easy to adjust, including an electric slide rail, and adjustment and guidance components are arranged at both ends of the electric slide rail;

[0007] The adjusting and guiding component includes a sliding table arranged at one end of the electric slide rail. A connecting block is installed on the top of the sliding table through bolts. An installation groove is formed on one side of the connecting block. A triangular plate is arranged in the installation groove, and the triangular plate is rotatably connected to the connecting block through a pin;

[0008] One end of the triangular plate is provided with a pin plate with adjustable angle. A reinforcing plate is arranged on one side of the pin plate, and the pin plate is detachably connected to the reinforcing plate.

[0009] It can be seen that in the above technical solution, the sliding table, the connecting block and the triangular plate are driven to displace, realizing the function of firstly adjusting the positions of the pin plate and the reinforcing plate, adjusting the distance between the adjusting and guiding components, enabling them to be located on both sides of the mold, and facilitating the guiding of the workpiece.

[0010] Optionally, in a possible implementation manner, a through groove is formed through one end of the triangular plate away from the pin plate. A pulley is slidably connected in the through groove. A connecting cover is arranged on the pulley, and the connecting cover is rotatably connected to the pulley. The connecting cover covers the outside of the triangular plate. A hydraulic rod is arranged on one side of the connecting cover. The hydraulic rod is installed on one side of the sliding table. The output end of the hydraulic rod penetrates through the sliding table and extends to the connecting cover. The hydraulic rod is detachably connected to the sliding table. A cover plate is inserted into the top of the sliding table, and a slider is arranged at the bottom of the sliding table. The slider is slidably connected to the electric slide rail;

[0011] It can be seen that in the above technical solution, when the hydraulic rod is started, the output end of the hydraulic rod drives the connecting cover to drive the pulley to displace. When the pulley displaces, it rubs against the through groove, causing the triangular plate to rotate along the axis point of the connection between the triangular plate and the connecting block, and then enabling the pin plate and the reinforcing plate to be adjusted again in terms of angle and position, realizing the diversity and convenience during adjustment.

[0012] Technical effects and advantages of the present utility model:

[0013] By setting the adjusting and guiding component, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the sliding table, the connecting block and the triangular plate are displaced, realizing the function of firstly adjusting the positions of the pin plate and the reinforcing plate, adjusting the distance between the adjusting and guiding components, enabling them to be located on both sides of the mold, and facilitating the guiding of the workpiece;

[0014] And the output end of the hydraulic rod drives the connecting cover to drive the pulley to displace. When the pulley displaces, it rubs against the through groove, causing the triangular plate to rotate along the axis point of the connection between the triangular plate and the connecting block, and then enabling the pin plate and the reinforcing plate to be adjusted again in terms of angle and position, realizing the diversity and convenience during adjustment.

The spacing between each adjustment and dredging component is adjusted so that it can be located on both sides of the crystallizer, which is convenient for dredging the workpiece. When the pulley 9 is displaced, it rubs against the through groove 8, so that the triangular plate 5 rotates along the axis point of the connection between the triangular plate 5 and the connecting block 3, and then the shaft pin plate 6 and the reinforcing plate 7 can be adjusted in angle and position again, so as to realize the diversity and convenience during adjustment, and the specific structure of the component is arranged as follows;
