Description

Technical Field

[0001] This utility model relates to the field of crystallizer technology, specifically to a hydraulic clamping device for the frame of a crystallizer. Background Technology

[0002] The crystallizer is a key piece of equipment used in the continuous casting process in the metallurgical industry. Its main function is to form the required shape during the solidification of molten metal. In order to ensure the stability and sealing of the crystallizer during operation, a frame hydraulic clamping device is usually used to fix the various parts of the crystallizer.

[0003] In the existing technology, a crystallizer wide-face clamping device with publication number CN201940565U is used. The single-acting hydraulic cylinder used in this structure is an independent hydraulic component. The pull rod, disc spring seat, disc spring and pressure cover can be pre-assembled into independent parts. It is not only easy to assemble and simple in structure, but also ensures the safety of steel pouring in the crystallizer, avoids accidental steel leakage, and can also realize online heat adjustment.

[0004] However, in the above structure, when the frame needs to be aligned with other machines after it is clamped and fixed, the clamping distance is not fixed, which causes the clamping to shift and requires readjustment of the clamping position, resulting in increased labor costs and wasted time and effort. Utility Model Content

[0005] The purpose of this invention is to provide a hydraulic clamping device for a crystallizer frame. This device solves the problem that the clamping may shift due to the non-fixed clamping distance, requiring readjustment of the clamping position.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic clamping device for a crystallizer frame, comprising a base plate, wherein the upper end of the base plate is provided with a transverse clamping assembly for horizontally clamping the frame and a vertical clamping assembly for vertically clamping the frame, and the lower end of the base plate is provided with a support leg;

[0007] The lateral clamping assembly includes a motor A mounted on the upper part of the base plate. The output end of the motor A is provided with a rotating shaft, and the upper end of the rotating shaft is provided with a gear. The upper part of the base plate is provided with a fixing block, and there are two sets of fixing blocks. The upper ends of the two sets of fixing blocks are provided with limit plates, and a sliding plate is slidably connected between the two sets of limit plates. A toothed block is provided on one side of the sliding plate, and the toothed block meshes with the gear. A fixing plate is provided on one side of the fixing plate, and a rubber pad A is engaged with one side of the fixing plate.

[0008] Furthermore, a fixed shaft is provided on one side of the base plate, and a support plate is rotatably connected to one side of the fixed shaft.

[0009] Furthermore, a fixing rod is provided at the upper end of the base plate, and two sets of fixing rods are provided. One set of fixing rods is provided with a motor B on one side, and a winding roller is provided at the output end of the motor B. A rope is sleeved on the outer surface of the winding roller.

[0010] Furthermore, the rope is provided in two sets, and the other end of the rope is fixedly connected to the support plate.

[0011] Furthermore, the vertical clamping assembly includes a slide rail disposed on the upper end of the base plate, a hydraulic cylinder disposed on the inner wall of the slide rail, a slider slidably connected inside the slide rail, and the telescopic end of the hydraulic cylinder being fixedly connected to the slider.

[0012] Furthermore, a movable plate is provided on one side of the slider, and a rubber pad B is engaged with the lower end of the movable plate. Engaging grooves are provided on one side of both the movable plate and the fixed plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model proposes a hydraulic clamping device for a crystallizer frame. Through the arrangement of a base plate, motor A, rotating shaft, gears, toothed blocks, a fixing plate, rubber pads A, a fixing block, and a limiting plate, the crystallizer frame is placed on the base plate. The rotation of motor A drives the gears to rotate, causing the meshing toothed blocks to move horizontally. Two sets of meshing toothed blocks can simultaneously move in opposite directions at equal distances until both sets of rubber pads A contact and clamp the frame. At this point, motor A stops running. Rubber pads A protect the frame, reducing the risk of damage from excessive clamping during the clamping process. This ensures that the clamping distances on both sides are equal, keeping the frame in the clamping center position and preventing frame misalignment due to uneven clamping centers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0022] Combination Figure 1 A hydraulic clamping device for a crystallizer frame includes a base plate 1. The upper end of the base plate 1 is provided with a transverse clamping component 2 for transversely clamping the frame and a vertical clamping component 6 for clamping the frame vertically. The lower end of the base plate 1 is provided with a support leg 11.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1:

The output end of the motor A21 is provided with a rotating shaft 22. A gear 23 is mounted on the upper end of the rotating shaft 22. A fixing block 7 is mounted on the upper end of the base plate 1. Limiting plates 71 are provided on the upper ends of the two sets of fixing blocks 7. There are two sets of limiting plates 71. A sliding plate 27 is slidably connected between the two sets of limiting plates 71. A toothed block 24 is provided on one side of the sliding plate 27. The toothed block 24 is meshed with the gear 23. A fixing plate 25 is provided on one side of the sliding plate 27. A rubber pad A26 is engaged with one side of the fixing plate 25.

[0026] Specifically, the crystallizer frame is placed on the base plate 1. The motor A21 rotates, driving the gear 23 to rotate, causing the meshing toothed blocks 24 to move horizontally. The two sets of meshing toothed blocks 24 can move in opposite directions at the same distance until the two sets of rubber pads A26 contact the frame and clamp it. Then the motor A21 stops running. The rubber pads A26 can protect the frame and reduce the possibility of damage caused by excessive clamping during the frame clamping process. This ensures that the clamping distance on both sides is equal, so that the frame is in the clamping center position, avoiding the situation where the frame is fixed and offset due to uneven clamping center.

A rubber pad B64 is engaged at the lower end of the moving plate 63. Engaging grooves 3 are provided on one side of both the moving plate 63 and the fixed plate 25.

[0029] Specifically, motor B51 controls the rotation of winding roller 53, adjusts the length of rope 52 to change the angle and position of support plate 4, and support plate 4 is rotatably connected through fixed shaft 12, so that support plate 4 can rotate around fixed shaft to adjust angle. Support plate 4 contacts the ground, which facilitates the crystallizer to feed material from support plate 4 into bottom plate 1. Hydraulic cylinder 62 is used to push slider 65 to slide along slide rail 61. Rubber pad B64 is provided at the lower end of moving plate 63 to increase friction and protect the surface of clamped frame.
