Description

Technical Field

[0001] This utility model belongs to the technical field of continuous casting equipment, specifically relating to a support structure for installing continuous casting rolls. Background Technology

[0002] In steel continuous casting production, the continuous casting roll is a core component that undertakes the key functions of supporting and conveying high-temperature billets and implementing pressure deformation. The reliability of its support structure directly affects the quality of the continuous casting billets, equipment operating efficiency, and maintenance costs.

[0003] Traditional continuous casting rolls often employ a segmented roll design, using multiple small-diameter roll sections combined with intermediate support bearing seats to support the cast billet. Some continuous casting machines use integral continuous casting rolls, but the support structure still relies on the direct connection between the built-in bearing seats and the frame. During the installation of the continuous casting roll and the support frame, the devices for fixing the bearings are mostly fixed and cannot be adjusted in distance. This means that the support frame can only support continuous casting rolls of a fixed diameter and cannot adjust the position of the fixing mechanism according to the diameter of the continuous casting roll, thus reducing the scope of application of the support frame and decreasing its practicality and convenience. Therefore, a support structure for installing continuous casting rolls is proposed to solve the above problems. Utility Model Content

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] In this embodiment, see Figure 1-4 A support structure for installing a continuous casting roll includes a support column 2 and a fixed box 6. An adjustable clamping assembly is provided on the outside of the support column 2. The adjustable clamping assembly includes a mounting box 91, which is located outside the fixed box 6. A lead screw 92 with one end extending into the inside of the fixed box 6 is rotatably mounted on the inner wall of the mounting box 91. Two moving blocks 93 are threadedly connected to the surface of the lead screw 92. A connecting rod 94 with one end extending into the outside of the fixed box 6 is provided on the outside of each of the two moving blocks 93. A clamping block 95 is provided on the surface of each of the two connecting rods 94. A worm gear 96 is fixedly mounted on the surface of the lead screw 92. A worm 97 with one end extending into the outside of the mounting box 91 is rotatably connected to the inner wall of the mounting box 91.

[0020] It should be added that both clamping blocks 95 are arc-shaped when viewed from the front. The purpose of this is to make the inner wall fit against the surface of the bearing housing, so that the clamping blocks 95 can be more firmly fixed to the surface of the bearing housing, achieving the purpose of limiting the installation of the bearing housing and improving the convenience of bearing housing installation. Two moving slots are opened on the top of the fixed box 6, and the surfaces of the two connecting rods 94 are slidably connected to the inner walls of the two moving slots respectively. At the same time, a weld overlay layer is required on the bottom of the bearing housing to prevent cooling water from entering the moving slots in the water spray operation environment, thereby avoiding damage to the internal components of the fixed box 6 and corrosion of the bearing housing, indirectly extending the service life of the continuous casting roll.

[0021] Since the worm gear 96 and the worm 97 have a self-locking function, after the worm 97 drives the worm gear 96 to rotate, there is no need to set up a fixing device. When the operator does not rotate the worm 97, the worm gear 96 will not drive the lead screw 92 to rotate.

[0022] Technical effect: By using the cooperation of lead screw 92, moving block 93, connecting rod 94, clamping block 95, worm gear 96 and worm 97, the distance between the two clamping blocks 95 can be adjusted, so that the two clamping blocks 95 can fix bearing seats of different diameters, and the support frame can install and support continuous casting rolls of different sizes, improving the convenience of installation and also making the support frame more widely used.

[0023] Optionally, see Figure 2-3 It also includes a base plate 1, a pad 3 is provided below the support column 2, an angle steel 4 is provided between the surface of the support column 2 and the pad 3, and the pad 3 and the base plate 1 are connected by a bolt assembly 5.

[0024] It should be noted that the setting of angle steel 4 can increase the firmness between support column 2 and pad plate 3, and at the same time facilitate more secure support for continuous casting roll, making continuous casting roll safer during use, indirectly improving the working efficiency of continuous casting roll, and facilitating better support for continuous casting roll.

[0025] Technical effect: The use of the pad 3 and bolt assembly 5 together can make the support column 2 more secure, thus making the support column 2 more stable when supporting the continuous casting roll, avoiding the continuous casting roll from shaking during use, and improving the stability of the continuous casting roll installation.

[0026] Optionally, there are two support columns 2 and two fixing boxes 6. The two fixing boxes 6 are respectively located above the two support columns 2. A support rod 7 connects the two fixing boxes 6. Two reinforcing columns 10 are provided between the lower part of the support rod 7 and the upper part of the pad 3. The two reinforcing columns 10 are connected by a hinge. The purpose of providing the support rod 7 and the reinforcing columns 10 is to make the connection between the two fixing boxes 6 more stable, and at the same time to reinforce the connection between the two support columns 2 and the base plate 1, so that the continuous casting roll will not loosen during installation.

[0027] Optionally, a pad 98 is provided above each of the two fixed boxes 6, and the two pads 98 are located in the same horizontal direction.

[0028] In addition, in the actual use of the pad 98, the actual material selected for the pad 98 should be a material with a certain hardness and corrosion resistance. At the same time, the hardness requirement comes from the pressure required by the steel billet on the bearing seat. In addition, the height of the pad 98 can be set according to the installation requirements of the continuous casting roll. At the same time, the pad 98 needs to be placed on top of the weld overlay. If the weld overlay is uneven during welding, it needs to be finely machined. The height range of the weld overlay after fine machining can be set to 1.5-2.5mm.

[0029] Technical effect: By setting the pad 98, the purpose is to improve the sealing of the continuous casting roll installation, thereby making the continuous casting roll safer to use.

[0030] Optionally, the worm 97 is provided with a handle at one end outside the mounting box 91. The worm 97 is located above the worm wheel 96, and the surface of the worm 97 meshes with the surface of the worm wheel 96. Its function is to allow the worm 97 to drive the worm wheel 96 to rotate, which in turn causes the worm wheel 96 to drive the lead screw 92 to rotate, while adjusting the distance between the two clamping blocks 95.

[0031] Optionally, the surface of the lead screw 92 is provided with two different types of threads, and the two threads are in opposite directions. The end of the lead screw 92 extends to the fixed box 6 and is rotatably connected to the inner wall of the fixed box 6, so that the lead screw 92 can drive the two clamping blocks 95 to move in opposite directions at the same time, thereby enabling the two clamping blocks 95 to clamp and fix the bearing seat at the same time.

[0032] Among them, anti-slip pads are provided between the opposite sides of the two clamping blocks 95. The purpose is to ensure that the clamping blocks 95 do not loosen during the clamping process of the bearing housing, thereby improving the stability of the bearing housing installation.

[0033] Optionally, each of the two moving blocks 93 is provided with a limiting block below it. The inner wall of the fixed box 6 is provided with two limiting grooves. The surfaces of the two limiting blocks are slidably connected to the inner walls of the two limiting grooves, which can limit the two moving blocks 93, so that the two moving blocks 93 can move left and right under the action of the screw 92, which is convenient for clamping and fixing the continuous casting roll.

[0034] Optionally, two adjustable clamping components are provided, with the two adjustable clamping components located above the two support columns 2 respectively, so as to clamp and fix the continuous casting roll from different directions, thereby preventing the continuous casting roll from loosening during use and improving the stability of the continuous casting roll installation.

[0035] Working principle: When installing continuous casting roll bodies 8 of different diameters, firstly, place the two bearing seats of the continuous casting roll body 8 above the two fixed boxes 6, and place them on the two pads 98 and the two weld overlay layers. Then, rotate the worm gear 97, causing the worm gear 97 to drive the worm wheel 96 to rotate clockwise. The worm wheel 96 drives the lead screw 92 to rotate clockwise. The lead screw 92 simultaneously drives the two connecting rods 94 to move to the opposite side. The two connecting rods 94 simultaneously drive the two clamping blocks 95 to move to the opposite side. The two clamping blocks 95 clamp and fix the bearing seats from both sides. At the same time, the adjustable clamping device on the other side performs the same operation. Thus, the continuous casting roll body 8 can be clamped and fixed from different directions, thereby completing the installation and support of bearing seats of different diameters.
