Description

Technical Field

[0001] This utility model belongs to the field of T-beam anti-overturning technology, and more specifically, relates to a T-beam anti-overturning device. Background Technology

[0002] In highway and railway bridge construction projects, T-beams are a commonly used main beam structure due to their rational cross-sectional shape, excellent load-bearing performance, and convenient construction. They are widely used in the construction of both simply supported beam bridges and continuous beam bridges. However, throughout the entire process of T-beams—from storage and transportation after precast casting to the bridge erection site, and finally to their installation using bridge erecting machines or cranes—their "wider at the top and narrower at the bottom" cross-sectional characteristics result in a relatively high center of gravity. This makes them highly susceptible to overturning accidents under external load disturbances (such as wind, lifting impact, and transport bumps) or support imbalances. Such accidents not only damage the T-beam structure and construction equipment but can also lead to serious casualties, directly impacting the safety, economy, and progress of the project. Therefore, T-beam anti-overturning devices, as core auxiliary equipment to ensure construction safety, are widely used at various bridge construction sites. However, with the diversification of bridge design and the increasing complexity of construction environments, existing T-beam anti-overturning devices have revealed many technical bottlenecks in practical applications. In particular, they are significantly lacking in the convenience and accuracy of device height adjustment and the flexibility of support member connection angles. This results in limited adaptability to different working conditions and makes it difficult to effectively ensure the stable support of T-beams in complex environments, which has become a prominent technical problem restricting construction efficiency and safety.

[0003] To address the aforementioned issues, various improvement schemes have been proposed in existing technologies to enhance the adaptability and stability of T-beam anti-tipping devices. Common solutions mainly include employing a telescopic support rod structure, achieving height adjustment through threaded sleeves, hydraulic cylinders, or segmented pin connections. For example, some devices use multiple sets of positioning holes on the support column, coupled with pins, to lock the height, thus adapting to different T-beam installation elevations; other technical solutions introduce screw lifting mechanisms or jack structures, allowing for continuous or graded adjustment of the support height through rotation.

[0004] Despite numerous explorations in structural forms and adjustment methods, existing technologies still exhibit significant shortcomings in practical applications, preventing them from fundamentally solving the problems of existing T-beam anti-tipping devices. For instance, existing height adjustment methods are generally cumbersome to operate and lack precision. While the adjustment method based on positioning holes and pins is structurally simple, the adjustment step size is limited by the hole spacing, making it difficult to achieve millimeter-level precise positioning. Furthermore, each adjustment requires disassembling the pins and realigning the holes, which is time-consuming and labor-intensive, severely impacting construction efficiency. Secondly, existing devices are weak in achieving T-beam hoisting and centering functions. Most devices only provide lateral limiting and lack active guidance and fine-tuning centering mechanisms, resulting in repeated manual adjustments when the T-beam is in place, increasing operational risks. In addition, height adjustment and angle adjustment functions are often independent and lack linkage and coordination, making it difficult to achieve rapid and accurate comprehensive adaptation in multi-dimensional space, limiting the versatility and reliability of the device under complex working conditions.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please refer to the figure. This utility model provides a T-beam anti-overturning device, comprising: a base plate 1, a height adjustment assembly 2, an angle adjustment assembly 3, and a first pressure plate 4; wherein: The substrate 1 is a square plate, and scales 101 are provided on both sides along its length. The bottom ends of the two height adjustment components 2 are respectively hinged to the upper surface of the substrate 1 and arranged in a mirror symmetrical manner with respect to the center line of the substrate 1, for adjusting the height of their top ends; The angle adjustment component 3 is fixedly mounted on the upper end of the height adjustment component 2, and the upper end of the angle adjustment component 3 is detachably connected to the first pressure plate 4. It is used to adjust the angle of the first pressure plate 4 so that the first pressure plate 4 adapts to and presses the connection between the T-beam flange and the web.

[0024] During use, the coordinated operation of the base plate 1, height adjustment component 2, angle adjustment component 3, and first pressure plate 4 effectively solves the technical problems of inconvenient height adjustment, fixed support angle, difficulty in centering, and poor versatility in existing anti-tipping devices. Specifically, the base plate 1, as the foundational support platform of the entire device, has a square structure with markings 101 on both sides along its length. This facilitates quick determination of the device's lateral position relative to the T-beam centerline during T-beam hoisting using visual inspection or measuring tools, achieving initial centering and significantly improving installation efficiency and accuracy. Simultaneously, the two height adjustment components 2 are mirror-symmetrically arranged about the centerline of the base plate 1, ensuring not only balanced structural stress and improved overall stability, but also ensuring that their bottom ends are aligned with the base plate 1. The upper surface is hinged, allowing for flexible adjustment of the tilt angle of the height adjustment component 2 within a certain range. This enables continuous and precise adjustment of the spatial height of the first pressure plate 4, adapting to the T-beam support requirements under different elevation conditions. Secondly, the angle adjustment component 3 is fixedly mounted on the upper end of the height adjustment component 2 and is detachably connected to the first pressure plate 4. This allows the direction of the first pressure plate 4 to be freely adjusted according to the actual tilt angle at the connection between the T-beam flange and the web, ensuring that the upper surface of the first pressure plate 4 can closely fit the corner of the T-beam structure, effectively transmitting lateral constraint force, preventing slippage and stress concentration, and greatly enhancing the reliability and adaptability of the support. Furthermore, this detachable connection method facilitates the disassembly, transportation, and maintenance of the device, improving the convenience of on-site operation.

[0025] In an optional embodiment, the base plate 1 is composed of a truss and multiple rust-proof steel plates disposed around the truss. This ensures the overall strength and load-bearing rigidity of the base plate 1 while significantly reducing its weight, facilitating on-site handling and installation. It is understood that the "around the truss" refers to the two sides, bottom surface, and top surface of the base plate 1 along its length, thereby further reducing its weight while meeting strength requirements and providing openings on both sides for easy handling.

[0026] In an optional embodiment, the scale 101 is a zero-point centered scale, and the zero-point line coincides with the center line of the side. This is used to quickly determine the lateral position of the device relative to the center line of the T-beam by visual inspection or measuring tools during the T-beam hoisting process, so as to achieve preliminary centering and positioning, and significantly improve installation efficiency and accuracy.

[0027] In an optional embodiment, at least one horizontal bubble 102 is embedded on the upper surface of the substrate 1, and the horizontal bubble 102 is not located in the area between the two angle adjustment components 3, in order to avoid installation interference and reduce the risk of construction collision. At the same time, the horizontal and longitudinal horizontal status of the substrate 1 can be monitored in real time to ensure that the device is placed stably, effectively prevent the support from becoming unstable due to foundation tilt, and improve the installation accuracy and safety of the T-beam anti-overturning device under complex terrain conditions.

[0028] In an optional embodiment, the upper end of the first pressure plate 4 is arc-shaped or L-shaped, and the upper surface is covered with a rubber pad to better fit the corner profile at the connection between the flange plate and the web of the T-beam, increase the contact area, and distribute the pressure evenly; in addition, the rubber pad can effectively prevent the first pressure plate 4 from damaging the concrete surface of the T-beam, while increasing the friction and preventing slippage.

[0029] Furthermore, the height adjustment assembly 2 includes an outer tube 201, an inner support rod 202, and an electro-hydraulic rod 203; the bottom end of the outer tube 201 is hinged to the upper surface of the substrate 1; the electro-hydraulic rod 203 is disposed inside the outer tube 201, and its movable end is connected to the bottom end of the inner support rod 202; the top end of the inner support rod 202 extends out of the outer tube 201 and is connected to the angle adjustment assembly 3.

[0030] Understandably, the continuous height adjustment of the inner support rod 202 via the telescopic drive of the electro-hydraulic rod 203 offers advantages such as rapid response, precise control, and strong load-bearing capacity. This significantly improves the automation level and operational efficiency of height adjustment. Furthermore, the hinged structure allows for adaptation to multi-directional tilting conditions, enhancing the adaptability and stability of the T-beam anti-tipping device in complex environments. Simultaneously, the inner support rod 202 bears the main supporting force, effectively distributing the load and preventing excessive direct stress on the electro-hydraulic rod 203. This protects the electro-hydraulic rod 203 from external impacts, bending moment damage, and potential collision damage during T-beam hoisting, extending its service life.

[0031] In an optional embodiment, at least two bushings are fixedly provided on the inner wall of the outer sleeve 201; the inner support rod 202 passes through multiple bushings and its outer diameter is adapted to the inner diameter of the bushings, which is used to guide the inner support rod 202 through the cooperation of the bushings and the inner support rod 202, effectively improving the coaxiality and movement stability of the inner support rod 202 during the lifting process, reducing swaying and off-center load; at the same time, it reduces metal-to-metal friction and wear, protects the surfaces of the outer sleeve 201 and the inner support rod 202, extends the service life of the height adjustment component 2, and ensures the reliability and accuracy of the device in long-term operation.

[0032] In an optional embodiment, the outer surface of the inner support rod 202 is provided with a scale along its length, which is used to combine with the scale 101 and the level bubble 102 on the base plate 1 to realize the visualization and precise quantification of the height adjustment process. This makes it easy for construction personnel to read the extension and contraction in real time, ensure that the height adjustment components 2 on both sides are adjusted synchronously, avoid the first pressure plate 4 from tilting or uneven force due to height deviation, improve the centering accuracy and stability of the T-beam support, and enhance the convenience of device operation and the accuracy of control.

[0033] In an optional embodiment, an inspection door 201a is provided on the outer wall of the outer sleeve 201 away from the middle region of the base plate 1, which is used to facilitate regular inspection, maintenance and troubleshooting of key components such as the internal electro-hydraulic rod 203 and bushings without disassembling the overall structure, significantly improving the maintainability and reliability of the device; in addition, this layout avoids opening holes in areas of concentrated stress, ensuring the structural strength of the outer sleeve 201, while facilitating quick on-site maintenance and ensuring the long-term stable operation of the T-beam anti-overturning device.

[0034] Furthermore, the angle adjustment component 3 includes a ball head 301 and a ball head seat 302; the ball head 301 is located at the upper end of the inner support rod 202; the bottom end of the ball head seat 302 is provided with a ball socket that is adapted to the ball head 301, and forms a spherical pair structure with the ball head 301; the ball head seat 302 is detachably connected to the first pressure plate 4.

[0035] It is understandable that the spherical joint structure of the ball head 301 and the ball head seat 302 allows the first pressure plate 4 to deflect flexibly in multiple directions, ensuring that its upper surface is in close contact with the inclined surface at the connection between the T-beam flange and the web, thus improving contact reliability; in conjunction with the detachable connection, it facilitates installation and replacement, enhancing the adaptability and practicality of the device.

[0036] It should be noted that in this embodiment, the ball head seat 302 is detachably connected to the first pressure plate 4 by bolts. In other embodiments, other types of detachable connection methods may be used, which are not specifically limited here.

[0037] In an optional embodiment, the anti-tipping device further includes a diagonal brace 5, which is a hydraulic telescopic rod. One end of the diagonal brace is hinged to the upper surface of the base plate 1, and the other end is hinged to the outer wall of the outer sleeve 201. It is used to extend and retract synchronously during height adjustment, providing additional lateral support force, effectively enhancing the bending stiffness and overall stability of the height adjustment component 2 in the tilted state, and significantly improving the anti-tipping ability and structural reliability of the device under complex working conditions.

[0038] In an optional embodiment, the anti-overturning device further includes limiting members 6, with multiple limiting members 6 symmetrically arranged on both sides of the web of the T-beam; each limiting member 6 includes: an L-shaped limiting member body 601, a first bolt 602, a second bolt 603, and a second pressure plate 604; wherein: The limiting member body 601 is formed by connecting a horizontal plate 601a and a vertical plate 601b; The first bolt 602 passes through a matching threaded hole on the horizontal plate 601a and is connected to a matching threaded hole on the upper surface of the base plate 1, for driving the horizontal plate 601a to press the bottom protruding structure of the T-beam web. The second bolt 603 passes through a matching threaded hole on the vertical plate 601b, and its end is threadedly connected to one side of the second pressure plate 604. The second pressure plate 604 faces the web of the T-beam on one side, and a rubber pad is provided on that side.

[0039] Understandably, the compact and flexible design of the limiting component 6, combined with the bidirectional bolt tightening mechanism, enables dual constraint of the T-beam in both the lateral and transverse directions, significantly improving the overall stability and safety of the anti-overturning device. It is especially suitable for precise positioning and reliable fixing under complex stress conditions.

[0040] In an optional embodiment, there are at least two of the first bolt 602, the second bolt 603, and the second pressure plate 604, and the second bolt 603 and the second pressure plate 604 correspond one-to-one. This is used to improve the uniformity of the constraint force of the limiting member 6 on the T-beam and the overall stability. In addition, it effectively avoids device eccentricity or local stress concentration caused by single-point force, enhances the anti-overturning ability, and improves the adjustment accuracy and connection reliability, ensuring the safety and stability of the T-beam during the hoisting process.

[0041] The working principle of this utility model is as follows: Before the T-beam hoisting construction, the base plate 1 is first placed stably in the predetermined support position, and the level bubble 102 is used to ensure that the base plate is in a horizontal state. Then, by observing that the scale 101 on the side of the base plate 1 is aligned with the center line of the T-beam, the initial horizontal centering is achieved. The level bubble 102 embedded in the upper surface of the base plate 1 is used to adjust the horizontal state to ensure the stability of the foundation. Subsequently, the electric hydraulic rod 203 in the height adjustment component 2 is activated to drive the inner support rod 202 to rise and fall along the outer sleeve 201. By reading the scale on the surface of the inner support rod 202, the extension and retraction of the height adjustment components 2 on both sides are adjusted synchronously to achieve precise control of the height of the pressure plate 4. When the pressure plate 4 approaches the flange of the T-beam... At the connection point with the web, the spherical substructure formed by the ball head 301 and ball head seat 302 in the angle adjustment assembly 3 plays a role, allowing the pressure plate 4 to freely deflect in multiple directions in space, ensuring that its arc-shaped or L-shaped upper end is tightly attached to the corner of the T-beam, and the rubber pad effectively prevents slipping and protects the concrete surface; at the same time, the diagonal brace 5 acts as a hydraulic telescopic rod to adjust its length synchronously, providing additional lateral support force and enhancing the overall structural stability; then, the T-beam is double-constrained by multiple limiting components 6, that is, rotating the first bolt 602 causes the horizontal plate 601a to press down the bottom protruding structure of the T-beam, restricting lateral movement, and adjusting multiple second bolts 603 to drive the corresponding second pressure plate 604 to press the web of the T-beam, achieving lateral limitation.
