Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a cylindrical steel leveling device. Background Technology

[0002] In industrial production, construction, and heavy equipment installation, cylindrical steel sections are often used as core load-bearing components. The levelness of their installation directly determines the stability of the overall structure, the operational accuracy of the equipment, and its service life. For example, in steel structure buildings, horizontal imbalance of cylindrical steel supports may lead to uneven stress distribution in the overall frame, reduce the load-bearing capacity of the components, and cause localized stress damage, structural deformation, and even safety hazards with long-term use.

[0003] Currently, the industry primarily employs traditional, rudimentary methods for leveling cylindrical steel sections, which suffer from the following technical drawbacks: First, the "shim leveling method" is commonly used. This involves inserting metal shims (such as steel plates or iron sheets) of varying thicknesses based on the height difference between the cylindrical steel base plate and the mounting surface. This method requires repeated disassembly of the base plate and trial insertion of different shims, making the adjustment process cumbersome and inefficient. Furthermore, gaps can easily form between the shims due to insufficient fit, leading to loosening under vibration or load changes, resulting in secondary leveling deviations and extremely poor stability. Second, the "adjustable bolt leveling method" is used in some scenarios. This involves installing several adjusting bolts under the base plate, changing the support height by tightening the bolts. However, this method is not well-suited for cylindrical steel sections: due to their circular structure, the bolts must be distributed along the outer circumference of the base plate to fit the circular contour, which can easily lead to imbalances in the stress points, causing radial displacement of the cylindrical steel section. Additionally, the bolts are prone to corrosion due to long-term exposure, affecting subsequent maintenance and secondary adjustment capabilities.

[0004] In summary, existing cylindrical steel leveling technologies suffer from problems such as low adjustment efficiency, insufficient stability, and weak adaptability, making it difficult to meet the demands of modern industry for high-efficiency and high-stability installation of cylindrical steel components. There is an urgent need for a dedicated leveling device that can adapt to the characteristics of cylindrical steel structures and can be adjusted efficiently. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a cylindrical steel leveling device, which solves the technical problems of cumbersome operation and low efficiency in the prior art for cylindrical steel leveling.

[0006] According to one aspect, at least one embodiment of the present invention provides a cylindrical steel leveling device for installation on a base plate of a cylindrical steel section. The leveling device comprises jacks driven to the cylindrical steel section and a plurality of support blocks located below the base plate. The jacks are spaced apart along the outer periphery of the base plate and are used to drive one side of the cylindrical steel section up and down to adjust the overall levelness. The support blocks are spaced apart along the outer periphery of the base plate, each support block having a supporting inclined surface extending downward toward the center of the base plate. The supporting inclined surface abuts against and slides against the bottom of the base plate. The support blocks are configured to slide radially toward or away from the center of the base plate to support the leveled cylindrical steel section.

[0007] As a further technical solution, it also includes several baffles located at the bottom of the base plate, with one baffle on each side of each support block.

[0008] As a further technical solution, the supporting inclined surface has a groove, the base plate has a through hole located above the groove, and the base plate is provided with a limiting rod that passes through the through hole and slides with the through hole. The bottom end of the limiting rod extends into the groove, and the groove is provided with rack one and rack two distributed vertically. The teeth of rack one and rack two are arranged opposite each other. The bottom end of the limiting rod is rotatably provided with a gear. The gear meshes with rack one alone or with rack one and rack two simultaneously. The gear is configured to follow the limiting rod down and mesh synchronously with rack one and rack two to lock the position of the support block; the gear follows the limiting rod up and meshes with rack one to release the locking of the support block.

[0009] As a further technical solution, a baffle is provided at the top of the limiting rod, and an elastic element is connected between the baffle and the base plate. The elastic element is used to provide a force for the limiting rod to descend so that the gear meshes synchronously with the first rack and the second rack.

[0010] As a further technical solution, the support block is wedge-shaped or triangular.

[0011] As a further technical solution, a level is also provided on the base plate.

[0012] The beneficial effects of this utility model are as follows: In this invention, a structure in which several support blocks are spaced apart along the outer periphery of the base plate can adapt to the circular contour of the cylindrical steel base plate, ensuring that the supporting force of the support blocks on the base plate is evenly distributed along the outer periphery of the base plate. This avoids radial displacement of the cylindrical steel due to uneven distribution of support points, solving the problem of insufficient adaptability in existing adjustable bolt leveling methods. The support blocks are configured to slide closer to or further away from the center of the base plate to adjust the levelness. Unlike the shim leveling method, there is no need to repeatedly disassemble the base plate and try different sizes of shims, nor is there a need to tighten bolts as in the adjustable bolt leveling method. Height adjustment can be achieved simply by sliding the support blocks, simplifying the operation steps and improving the leveling efficiency. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] like Figure 1 , Figure 2The diagram illustrates the installation position of the leveling device on a cylindrical steel section 1 in one embodiment of the present invention. The leveling device is used to mate with the base plate 11 of the cylindrical steel section 1. The leveling device includes several support blocks 2 and jacks 7. The support blocks 2 are positioned below the base plate 11, and all support blocks 2 are arranged at intervals along the outer periphery of the base plate 11. The jacks 7 are positioned around the outer periphery of the base plate 11, and all jacks 7 are arranged at intervals along the outer periphery of the base plate 11. Each support block 2 has a supporting inclined surface 21, which extends towards the center of the base plate 11 and downwards. The supporting inclined surface 21 of the support block 2 contacts the bottom of the base plate 11, and relative sliding can occur between the supporting inclined surface 21 and the bottom of the base plate 11.

[0022] A mounting bracket can be extended radially along the side wall of the cylindrical steel section 1. The jack 7 can be driven by this mounting bracket to coarsely and finely adjust the levelness of the cylindrical steel section 1. The support block 2 can be moved radially by human power or with the help of external drives such as motors, hydraulic cylinders, electric push rods, etc.

[0023] In this embodiment, the level 6 can collect the levelness data of the cylindrical steel 1 in real time (such as X-axis deviation of 0.8° and Y-axis deviation of 0.3°) and transmit it to the PLC controller; the PLC controller judges the deviation threshold: if the deviation is >0.5°, it triggers coarse adjustment; if 0.05° < deviation ≤0.5°, it directly triggers fine adjustment (the preset allowable deviation is ≤0.05°).

[0024] During coarse adjustment, the PLC controller outputs a signal to jack 7. For every 0.5mm slide, the level 6 synchronously reports the deviation value, and the PLC controller dynamically adjusts the moving speed of jack 7. When the level deviation drops to 0.05°~0.1° (the acceptable range for coarse adjustment), the coarse adjustment ends. The PLC controller switches to "fine adjustment mode" and outputs a signal to jack 7, which is still at a low position after coarse adjustment, controlling the jack to slowly lift the base plate 11 with an accuracy of 0.1mm / step. For each lifting step, the level 6 checks once, until the deviation is ≤0.05°, at which point jack 7 stops moving, and the fine adjustment is completed.

[0025] During leveling, a locking block can be inserted below the boss 42 of the limiting rod 4 to raise the limiting rod 4, causing gear 41 to mesh with rack 212 but not with gear 213, thus releasing the lock on the support block 2. Then, the PLC controller can output a signal to the external drive of the support block 2, driving the corresponding support block 2 to move radially to support the base plate 11 of the cylindrical steel 1, keeping the whole structure stable.

[0026] The support block 2 is configured to slide either close to the center of the base plate 11 or away from the center of the base plate 11, thereby providing support for the cylindrical steel 1 before and after leveling. A bubble level can be used as the level instrument 6 to visually observe whether the levelness of the cylindrical steel 1 meets the requirements.

[0027] The leveling device is designed based on the inclined characteristics of the support ramp 21. By utilizing the sliding contact between the support ramp 21 and the bottom of the base plate 11, the base plate 11 is quickly supported by changing the position of the support block 2 relative to the center of the base plate 11. When the support block 2 slides closer to the center of the base plate 11, the support point where the support ramp 21 contacts the bottom of the base plate 11 rises along the ramp, thereby increasing the height of the base plate 11 at the corresponding position. When the support block 2 slides away from the center of the base plate 11, the support point where the support ramp 21 contacts the bottom of the base plate 11 falls downwards along the ramp, thereby decreasing the height of the base plate 11 at the corresponding position. The workflow is as follows: First, several support blocks 2 are arranged at intervals along the outer periphery of the base plate 11 below the base plate 11, so that the support slope 21 of each support block 2 forms an abutment fit with the bottom of the base plate 11; then, the levelness of the cylindrical steel 1 is checked, and leveling is achieved using jacks 7, while simultaneously driving the support blocks 2 to move to adapt to the adjusted height position of the base plate 11; for positions with low levelness, the corresponding support block 2 is pushed to slide towards the center of the base plate 11, thereby raising the height of the base plate 11 at that position by raising the support point of the support slope 21; for positions with high levelness, the corresponding support block 2 is pushed to slide away from the center of the base plate 11, thereby lowering the height of the base plate 11 at that position by lowering the support point of the support slope 21; the above sliding adjustment action is repeated until the levelness of the cylindrical steel 1 meets the requirements.

[0028] The structure of several support blocks 2 spaced apart along the outer periphery of the base plate 11 can adapt to the circular contour of the cylindrical steel base plate 11, so that the supporting force of the support blocks 2 on the base plate 11 is evenly distributed along the outer periphery of the base plate 11, avoiding radial displacement of the cylindrical steel 1 due to uneven distribution of support points, and solving the problem of insufficient adaptability in the existing adjustable bolt leveling method. The support blocks 2 are configured to slide closer to or further away from the center of the base plate 11 to adjust the levelness. Unlike the shim leveling method, there is no need to repeatedly disassemble the base plate 11 and try different specifications of shims, nor is there a need to tighten bolts like the adjustable bolt leveling method. The height can be adjusted simply by sliding the support blocks 2, which simplifies the operation steps and improves the leveling efficiency.

[0029] The leveling device also includes several baffles 3, which are set at the bottom of the base plate 11, with one baffle 3 on each side of each support block 2. The baffles 3, located on both sides of the support block 2, limit the displacement of the support block 2 along the outer periphery of the base plate 11, ensuring that the support block 2 can only slide in a direction close to or away from the center of the base plate 11. This prevents lateral displacement of the support block 2 during sliding adjustment and ensures the stability of the relative sliding direction between the support block 2 and the bottom of the base plate 11. Combined with the structure of the support blocks 2 spaced apart along the outer periphery of the base plate 11, the cooperation between the baffles 3 and the support blocks 2 limits the sliding trajectory of each support block 2, further ensuring the stability of the support position of each support block 2 on the base plate 11.

[0030] The cooperation between the baffle 3 and the support block 2 ensures that the support block 2 will not disengage from the preset support position during sliding. Combined with the surface contact support between the support inclined surface 21 and the bottom of the base plate 11, the stability of the leveling device during and after adjustment is further improved, avoiding uneven distribution of support force caused by lateral displacement of the support block 2. Compared with the existing adjustable bolt leveling method, which is prone to radial displacement of the cylindrical steel 1 due to the lack of a lateral limiting structure, the baffle 3 indirectly ensures that the cylindrical steel 1 will not undergo radial displacement during the leveling process by limiting the displacement direction of the support block 2, thus improving the adaptability of the device to the cylindrical steel 1.

[0031] like Figure 3 , Figure 4 The diagram illustrates the specific structure of the limiting rod 4, elastic element 5, gear 41, rack 1 212, and rack 2 213 in one embodiment of this utility model. A groove 211 is provided on the supporting inclined surface 21, and a through hole 111 is provided on the base plate 11, located above the groove 211. A limiting rod 4 is provided on the base plate 11, penetrating the through hole 111 and slidingly engaging with it. The bottom end of the limiting rod 4 extends into the groove 211. Rack 1 212 and rack 2 213 are arranged vertically within the groove 211, with their teeth facing each other. A gear 41 is rotatably mounted on the bottom end of the limiting rod 4. The gear 41 can mesh with rack 1 212 individually or simultaneously with both rack 1 212 and rack 2 213. A boss 42 is provided at the top of the limiting rod 4, and an elastic element 5 connects the boss 42 and the base plate 11. Its design principle is to use the elastic force of the elastic element 5 to keep the limiting rod 4 in a downward trend, ensuring that the gear 41 meshes synchronously with rack 1 212 and rack 2 213 in the non-adjustment state. When the level needs to be adjusted, a long rod is supported between the boss 42 and the base plate 11 to overcome the elastic force of the elastic element 5, causing the limiting rod 4 to rise, the gear 41 to separate from rack 2 213, and the support block 2 to slide and adjust; after the adjustment is completed, the long rod is removed, the elastic force of the elastic element 5 pushes the limiting rod 4 to fall, the gear 41 meshes synchronously with rack 1 212 and rack 2 213, and the position of the support block 2 is locked.

[0032] The elastic element 5 continuously applies a downward force to the boss 42, keeping the limiting rod 4 in the lowered position when not in operation. The gear 41 stably meshes with racks 212 and 213, preventing separation of gear 41 from the racks due to vibration or other factors, thus preventing accidental slippage of the support block 2 and enhancing the reliability of the locking mechanism. The boss 42 provides a force-bearing point for the elastic element 5, and the elastic force of the elastic element 5 is transmitted to the limiting rod 4 through the boss 42, ensuring uniform force distribution on the limiting rod 4 and guaranteeing the precise meshing of gear 41 and racks. Combined with the sliding fit between the limiting rod 4 and the through hole 111, this extends the service life of the device. The elastic element 5 eliminates the need for additional fixing structures during locking; unlocking is achieved simply by pulling with external force, simplifying operation. Combined with the sliding adjustment of the support block 2 and the locking function of the gears 41 and racks, this improves the overall efficiency of the leveling device.

[0033] The support block 2 has a wedge-shaped or triangular structure, which, combined with the requirement that the support ramp 21 extends downward toward the center of the base plate 11, allows the structure of the support block 2 itself to meet the requirements of the support ramp 21, eliminating the need for additional ramp processing, simplifying the manufacturing process of the support block 2, and reducing production costs. The wedge-shaped or triangular structure has high structural stability and strong compressive strength along the sliding direction. Combined with the support method of the support blocks 2 being spaced along the outer periphery of the base plate 11, it can evenly bear the load transmitted by the cylindrical steel 1, avoiding changes in support height caused by deformation of the support block 2, and improving support stability. The support block 2 of this shape has a compact structure, occupies little space, and can be flexibly arranged below the base plate 11, adapting to cylindrical steel 1 base plates 11 of different diameters, improving the adaptability of the device.
