Abstract
Description
Technical Field
[0001] This application relates to the field of mechanical maintenance equipment technology, and in particular to a support base and support equipment. Background Technology
[0002] In the field of deep steel processing, hot-rolled strip and plate production lines occupy an important position. The core of this production line lies in the working state of the rolling system, and the core of the rolling system is the mill support rolls. After a certain period of use, various impurities accumulate on the mill support rolls, thus requiring surface quality maintenance. Currently, the surface quality maintenance phase of the mill support rolls requires them to be taken offline. Then, the roll surface is ground, and the bearings inside the bearing housings are inspected, cleaned (or replaced), and necessary reagents such as lubricating oil are added. After this process, the contact surfaces of the assembled mill support rolls and bearing housings need to be cleaned, measured, and adjusted.
[0003] However, there is currently no specialized equipment for inspecting rolling mill support rolls. Inspection is typically carried out using a crane, but this crane-based method has the following problems:
[0004] (1) The hoisting inspection method poses a risk of instability or even falling of the mill support roller, which is a safety hazard. (2) The mill support roller will swing left and right during hoisting, making the measurement process unstable. Utility Model Content
[0005] This application provides a support base and support device to solve the following technical problem: how to improve the stability of rolling mill support rolls during the inspection process.
[0006] In a first aspect, embodiments of this application provide a support base for supporting rolling mill support rolls, the support base comprising:
[0007] Base plate;
[0008] Multiple support blocks are arranged in an array on the surface of the base plate. Two adjacent support blocks are symmetrically arranged with respect to the center line of the base plate. Two adjacent support blocks are inclined inward to form an inclined surface. Multiple inclined surfaces are symmetrically arranged to form a groove-shaped fixed space. There is a vertical distance between two adjacent support blocks, and the vertical distance is ≤100mm.
[0009] Optionally, the inclination angle of the inclined surface is 30° to 45°.
[0010] Optionally, the vertical distance is 50mm to 100mm.
[0011] Optionally, there is a horizontal distance between two adjacent support blocks, the start and end points of which are the geometric center points of the support blocks, and the horizontal distance is 650mm to 750m.
[0012] Optionally, the surface of the inclined surface is provided with an anti-slip flexible layer.
[0013] Optionally, the thickness of the anti-slip flexible layer is 15mm to 25mm.
[0014] Secondly, this application provides a support device, the support device comprising:
[0015] The support base described in the first aspect;
[0016] A support box, one end of which is fixedly connected to the support base;
[0017] A support plate is located at the other end of the support box away from the support base.
[0018] Optionally, the support box is provided with a plurality of grids, which are evenly distributed within the support box and abut against the support base.
[0019] Optionally, the outer side of the support box is provided with multiple lifting lugs, which are symmetrically distributed on both sides of the support box.
[0020] Optionally, the area of the support plate is larger than the area of the support box.
[0021] The technical solutions provided in this application have the following advantages compared with the prior art:
[0022] This application provides a support base that provides multiple support points for rolling mill support rolls by arranging support blocks on a base plate and arraying the support blocks on the base plate. The support blocks are symmetrically arranged relative to the centerline of the base plate, and adjacent support blocks are inclined inwards to form inclined surfaces. These inclined surfaces are symmetrically arranged to form a groove-shaped fixing space. The symmetrically arranged support blocks create a groove-shaped fixing space on the base plate. This groove-shaped fixing space better adapts to the cylindrical shape of the rolling mill support roll and provides better support force, improving the rolling mill support roll's performance during inspection. On the one hand, the groove-shaped fixed space can create a certain self-locking effect, resulting in a certain interaction force between the cylindrical shape of the mill support roll and the support block. At this time, the mill support roll will be clamped by the support block, preventing the mill support roll from sliding or displacing during the inspection process, thereby further improving the stability of the mill support roll during the inspection process. In addition, the vertical distance between the support blocks is ≤100mm, which makes the support blocks evenly distributed on the base plate. The evenly distributed support blocks can work with the fixed space to provide better fit and support force for the mill support roll, and deepen the self-locking effect, further improving the stability of the mill support roll during the inspection process.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] Various embodiments of this application may exist in the form of a range; it should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a hard limitation on the scope of this application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values within that range; for example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range; in addition, whenever a numerical range is indicated herein, it means including any referenced number (fraction or integer) within the indicated range.
[0031] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly.
[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "connection" and "fixation" should be interpreted broadly. For example, "fixation" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection, an electrical connection, or a magnetic connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0033] Unless otherwise specified, all raw materials, reagents, instruments and equipment used in this article can be purchased from the market or prepared by existing methods.
[0034] It should be noted that, regarding the prior art described in the background section, the inventors have also discovered that: the hoisted mill support rolls are generally at a high height, and manual operation requires standing for a long time, which can easily lead to fatigue and affect the accuracy of the inspection process.
[0035] Figure 1An exemplary schematic diagram of a support base provided in an embodiment of this application is shown;
[0036] like Figure 1 As shown in the figure, this application embodiment provides a support base for supporting rolling mill support rolls, the support base comprising:
[0037] Base plate 1;
[0038] Multiple support blocks 2 are arranged in an array on the surface of the base plate 1. Two adjacent support blocks 2 are symmetrically arranged with respect to the center line of the base plate 1. Two adjacent support blocks 2 are inclined inward to form an inclined surface 201. Multiple inclined surfaces 201 are symmetrically arranged to form a groove-shaped fixed space. There is a vertical distance between two adjacent support blocks 2, and the vertical distance is ≤100mm.
[0039] It should be noted that the bottom end of the support block 2 is set perpendicular to the base plate 1.
[0040] It should be noted that this application provides a support base, which, through a unique design structure, achieves stable support and efficient fixation for the rolling mill support rolls. The specific principle is as follows:
[0041] (1) The core feature of this support base is the design of the support blocks 2 on its base plate 1. These support blocks 2 are arrayed on the base plate 1 to provide multiple precise support points for the mill support rolls.
[0042] (2) The support blocks 2 are symmetrically arranged relative to the centerline of the base plate 1. This design ensures the balance of the support base under stress. At the same time, two adjacent support blocks 2 are inclined inward to form an inclined surface 201. Multiple inclined surfaces 201 are symmetrically arranged, thus forming a groove-shaped fixed space on the base plate 1. This groove-shaped fixed space design not only perfectly matches the cylindrical shape of the mill support roll, providing better fit and support force, but also forms a self-locking effect through its unique shape. When the mill support roll is placed in the fixed space, a certain interaction force is generated between its cylindrical shape and the support block 2, so that the support roll is subjected to the clamping force of the support block 2, which effectively prevents the mill support roll from sliding or displacing during inspection and significantly improves its stability.
[0043] (2) The vertical distance between the support blocks 2 is strictly controlled within 100mm. This design ensures that the support blocks 2 can be evenly distributed on the base plate 1. The evenly distributed support blocks 2 not only further enhance the load-bearing capacity of the support base, but also provide more comprehensive and stable support for the mill support rolls by cooperating with the groove-shaped fixing space. This design not only deepens the self-locking effect, but also allows the support base to flexibly adjust the position and number of support points when facing different load conditions to meet actual needs.
[0044] In summary, this application provides a support base that, through its unique design and layout of support blocks 2, symmetrically arranged support blocks 2, and evenly distributed support points, achieves stable, close, and efficient support for the mill support rolls. This design not only improves the stability of the mill support rolls during inspection but also ensures their safety through a self-locking effect, providing a strong guarantee for the efficient operation of the mill.
[0045] In some alternative embodiments, the tilt angle of the tilted surface 201 is 30° to 45°.
[0046] In these embodiments, the tilt angle of the inclined surface 201 can be 30° to 45°, so that the symmetrical support block 2 has a sufficient tilt angle. The symmetrical support block 2 with a sufficient tilt angle can form a groove-shaped fixed space with sufficient depth and tilt angle. This not only better adapts to the cylindrical shape of the mill support roll and provides better fitting support force for the mill support roll, but also forms a certain self-locking effect, so that there is a certain interaction force between the cylindrical shape of the mill support roll and the symmetrical support block 2, thereby improving the stability of the mill support roll during the inspection process.
[0047] The tilt angle of the inclined surface 201 can be 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44° or 45°.
[0048] In some alternative implementations, the vertical distance is 50mm to 100mm.
[0049] In these embodiments, the vertical distance can be 50mm to 100mm, which ensures that there is sufficient distance between the parallel support blocks 2 to effectively distribute the weight of the mill support rolls; in addition, there are multiple gaps between the parallel support blocks 2 that are sufficiently spaced, which also facilitates cleaning, measurement and adjustment operations by personnel.
[0050] The vertical distance can be 50mm, 60mm, 70mm, 80mm, 90mm or 100mm.
[0051] In some optional embodiments, there is a horizontal distance between two adjacent support blocks 2, the start and end points of which are the geometric center points of the support blocks 2, and the horizontal distance is 650mm to 750m.
[0052] In these embodiments, there is a horizontal distance between two adjacent support blocks 2, and the start and end points of the horizontal distance are both the geometric center points of the support blocks 2. The horizontal distance can be 650mm to 750mm, so that the fixed space formed by the support blocks 2 is large enough to accommodate the mill support roll and has a high degree of fit between the mill support roll and the support base. Furthermore, the unique shape of the fixed space forms a self-locking effect, thereby effectively preventing the mill support roll from sliding or displacing during inspection.
[0053] The horizontal distance can be 650mm, 660mm, 670mm, 680mm, 690mm, 700mm, 750mm, 720mm, 730mm, 740mm or 750mm.
[0054] In some alternative embodiments, the surface of the inclined surface 201 is provided with an anti-slip flexible layer 202.
[0055] In these embodiments, the surface of the inclined surface 201 may be provided with an anti-slip flexible layer 202. By providing an anti-slip flexible layer 202 on the surface of the inclined surface 201, not only can the fit between the mill support roll and the support base be increased, but the interaction force between the mill support roll and the support base during the self-locking effect stage can also be increased, preventing the mill support roll from sliding or displacing during the inspection process, thereby improving the stability of the mill support roll during the inspection process.
[0056] In some alternative embodiments, the thickness of the anti-slip flexible layer 202 is 15mm to 25mm.
[0057] In these embodiments, the thickness of the anti-slip flexible layer 202 can be 15mm to 25mm, ensuring that the anti-slip flexible layer 202 has sufficient thickness. The sufficiently thick anti-slip flexible layer 202 can not only increase the fit between the mill support roll and the support base, but also increase the interaction force between the mill support roll and the support base during the self-locking effect stage, preventing the mill support roll from sliding or displacing during inspection, and improving the stability of the mill support roll during inspection.
[0058] The thickness of the anti-slip flexible layer 202 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm or 25mm.
[0059] Figure 2 An exemplary structural schematic diagram of a support device provided in an embodiment of this application is shown;
[0060] Based on a general inventive concept, such as Figure 2As shown in the figure, this application embodiment provides a support device, the support device including:
[0061] The supporting base;
[0062] A support box 3 is provided, one end of which is fixedly connected to the support base;
[0063] Support plate 4 is located at the other end of the support box 3 away from the support base.
[0064] The support device is based on the support base described above. The specific structure of the support base can be referred to in the above embodiments. Since the support device adopts some or all of the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.
[0065] It should be noted that the support base, support box 3 and support plate 4 can all be made of 4cm high-quality Q345B steel.
[0066] It should be noted that the support base and the support box 3 can be fixedly connected by welding or adhesive; the support plate 4 and the support box 3 can be fixedly connected by welding or adhesive.
[0067] It should be noted that the support box 3 can be used as a lifting component for the support base, which can lift the mill support rolls on the support base, thereby facilitating the operation of maintenance personnel.
[0068] Figure 3 An exemplary schematic diagram of the structure of a support box for a support device provided in an embodiment of this application is shown;
[0069] In some alternative implementations, such as Figure 3 As shown, the support box 3 is provided with a plurality of grids 301, which are evenly distributed in the support box 3 and abut against the support base.
[0070] In these embodiments, the support box 3 may be provided with a plurality of grids 301, and the plurality of grids 301 are evenly distributed in the support box 3, and the grids 301 abut against the support base. The grids 301 can distribute the weight of the support base and the rolling mill support roll, so that the gravity of the support base and the rolling mill support roll is evenly distributed, thereby avoiding the support base from shaking during the lifting stage and further improving the stability of the rolling mill support roll during the inspection process.
[0071] It should be noted that the grid spacing of grid 301 can be designed according to the specific weight of the mill support roll and the support base, which can prevent the support base from shaking during the lifting stage and further improve the stability of the mill support roll during the inspection process.
[0072] In some optional embodiments, the outer side of the support box 3 is provided with a plurality of lifting lugs 302, and the plurality of lifting lugs 302 are symmetrically distributed on both sides of the support box 3.
[0073] In these embodiments, the outer side of the support box 3 may be provided with multiple lifting lugs 302. The multiple lifting lugs 302 are relatively symmetrically distributed on both sides of the support box 3. The support box 3 can be hoisted through the lifting lugs 302, thereby enabling the rapid arrangement of the support equipment.
[0074] In some alternative embodiments, the area of the support plate 4 is larger than the area of the support box 3.
[0075] In these embodiments, the area of the support plate 4 can be larger than the area of the support box 3, so that the support plate 4 can effectively distribute the weight of the support box 3, the mill support roll and the support base, which can prevent the support base from shaking during the lifting stage and further improve the stability of the mill support roll during the inspection process.
[0076] In summary, the support device provided in this application embodiment has the following usage process:
[0077] First, use a crane or gantry crane to hoist the support box 3, support base, and support plate 4 onto the ground via the lifting lug 302. Then, hoist the mill support roll onto the support base. At this time, the anti-slip flexible layer 202 of the inclined surface 201 of the support block 2 abuts against the cylindrical roll surface of the mill support roll. Through the fixed space between the support blocks 2 and the action of the anti-slip flexible layer 202, the mill support roll is stably placed on the support equipment, making it convenient for workers to carry out subsequent cleaning, measurement, and adjustment operations.
