Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling beam devices, in particular to an adaptive damping anti-falling beam device. Background Art

[0002] In bridge construction, the angle between the side and bottom surfaces of beams is often non-perpendicular. Due to factors such as construction errors and material deformation, the angle of each beam can vary. This inconsistency poses challenges to the installation and use of beam-fall prevention devices. Traditional beam-fall prevention blocks typically utilize rigid connections, which are difficult to adapt to variations in beam side angles. This results in difficult installation, poor connection quality, and even potential damage due to excessive internal stress in extreme conditions, such as earthquakes. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an adaptive damping anti-falling beam device.

[0004] The top of the lifting board is connected with the support of the lifting bridge, and the bottom of the lifting bridge is connected with the support of the lifting bridge.

[0005] Preferably, a circular groove is formed through the side wall of the damping plate.

[0006] Preferably, the side wall of the anti-buckling plate close to the damping plate is connected to the bottom plate through reinforcing ribs.

[0007] Preferably, the connecting structure includes a limit plate and a first limit groove. The limit plate is fixedly connected to the side wall of the adaptive side plate. The limit plate is provided with a first limit groove on the side wall away from the adaptive side plate. The end of the upper plate close to the adaptive side plate is a cylinder. The cylinder at one end of the upper plate is slidably engaged in the inside of the first limit groove. The adaptive side plate, upper plate, limit plate and first limit groove constitute a sliding pair.

[0008] Preferably, the connecting structure includes a connecting plate and a second limiting groove. The connecting plate is fixedly connected to the side wall of the adaptive side plate. The upper and lower surfaces of the connecting plate are connected to the adaptive side plate through reinforcing ribs. The side wall of the connecting plate away from the adaptive side plate is provided with a second limiting groove. The end of the upper plate close to the adaptive side plate is a cylinder. The cylinder at one end of the upper plate is slidably clamped in the inside of the second limiting groove. The adaptive side plate, upper plate, connecting plate and second limiting groove constitute a sliding pair.

[0009] Preferably, the connection structure includes a fixed roller and a fixed plate, the two fixed plates are fixedly connected to the side wall of the adaptive side plate close to the upper plate, the fixed roller is fixedly connected to one end of the upper plate close to the adaptive side plate, and the two ends of the fixed roller are respectively rotatably connected to the two fixed plates.

[0010] The utility model has the following beneficial effects:

[0011] 1. Traditional beam-fall prevention blocks are mostly made of rigid materials such as concrete and I-beams. Direct collisions between beams and blocks during earthquakes can easily lead to block damage or partial damage to the beam itself. This utility model uses steel blocks and creatively combines them with mild steel damping plates and steel cables. During an earthquake, the mild steel damping plates effectively dissipate seismic energy through elastic-plastic deformation, significantly reducing the seismic response of the bridge structure. When seismic forces exceed the design limit, the mild steel damping plates and steel cables work together to form a dual protection mechanism, effectively avoiding the risk of beam falls and ensuring the safety of the bridge structure.

[0012] 2. Considering that the sides and bottoms of beams are generally not perpendicular, and that the angles of each beam vary slightly, this utility model incorporates a cylindrical connection between the adaptive side panels and the upper panel. This design allows the adaptive side panels to flexibly adapt to the beam angle during installation, closely fitting the beam side for a better connection. Furthermore, the adaptive side panels can adapt to certain beam angles, preventing excessive stress within the anti-drop beam block and ensuring structural stability and durability.

[0013] 3. The sliding pairs formed by the adaptive side panels, upper panels, and connecting structures can adapt to the longitudinal displacement of the bridge under extreme conditions such as earthquakes. This design allows the bridge to deform to a certain extent during an earthquake, thereby absorbing and dissipating seismic energy and protecting the bridge structure from serious damage.

[0014] 4. To prevent excessive deformation on one side of the upper plate when subjected to horizontal force, which could affect the uniformity of the damping plate's force, the utility model incorporates an anti-buckling plate. This plate ensures uniform horizontal force on the damping plate, providing a stable damping force and further enhancing the bridge structure's seismic performance.

[0015] 5. The beam-fall prevention device of this utility model is installed sideways on the beam, providing ample space for daily inspection, maintenance, and subsequent replacement. This design not only improves work efficiency but also reduces maintenance costs, ensuring the long-term safe operation of the bridge structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0021] like Figure 1 As shown, an embodiment of the utility model provides an adaptive damping anti-falling beam device, including an adaptive side panel 1 and an upper panel 2. The side walls of the adaptive side panel 1 are fixedly connected with a connecting structure, which is connected to the upper panel 2. A bottom panel 6 is provided below the upper panel 2. Both side walls of the upper panel 2 and the bottom panel 6 are fixedly connected with connecting ears. The connecting ears on both sides of the upper panel 2 and the connecting ears on both sides of the bottom panel 6 are respectively connected by two steel cables 4. A plurality of damping plates 3 are equidistantly arranged between the two steel cables 4. A plurality of slots are equidistantly provided at the bottom of the upper panel 2 and the top of the bottom panel 6. The upper and lower ends of the plurality of damping plates 3 are respectively clamped in the bottom slots of the upper panel 2 and the top slots of the bottom panel 6. The top of the bottom panel 6 is fixedly connected with an anti-buckling plate 5. The anti-buckling plate 5 is located on the side of the damping plate 3 away from the adaptive side panel 1. The anti-buckling plate 5 is located below the upper panel 2. Both the adaptive side panel 1 and the bottom panel 6 are installed with a plurality of anchors 7.

[0022] The circular grooves running through the sidewalls of the damping plate 3 further optimize the stress state and deformation pattern of the damping plate 3. During an earthquake, the presence of the circular grooves allows the damping plate 3 to undergo more uniform elastic-plastic deformation, thereby more effectively dissipating seismic energy and reducing the seismic response of the bridge structure.

[0023] The sidewalls of the anti-buckling plate 5 near the damping plate 3 are connected to the base plate 6 via reinforcing ribs. This design significantly enhances the overall stability and load-bearing capacity of the anti-buckling plate 5. The presence of the reinforcing ribs allows the anti-buckling plate 5 to better resist deformation when subjected to stress, ensuring that the damping plate 3 is subjected to uniform horizontal force and providing a stable damping force.

[0024] The limiting plate 8 and first limiting groove 9 in the connecting structure, along with the adaptive side plate 1 and upper plate 2, form a sliding pair. This design allows the upper plate 2 to slide within the first limiting groove 9 when the bridge undergoes longitudinal displacement under extreme conditions such as earthquakes, thereby absorbing and dissipating seismic energy and protecting the bridge structure from serious damage. The sliding pair also enhances the flexibility and adaptability of the structure, allowing the anti-drop beam device to better adapt to the deformation requirements of different bridges. Example 2

[0025] like Figure 2 As shown, an embodiment of the utility model provides an adaptive damping anti-falling beam device, and the connecting structure includes a connecting plate 10 and a second limiting groove 11. The connecting plate 10 is fixedly connected to the side wall of the adaptive side panel 1, and the upper and lower surfaces of the connecting plate 10 are connected to the adaptive side panel 1 through reinforcing ribs. The side wall of the connecting plate 10 away from the adaptive side panel 1 is provided with a second limiting groove 11, and the end of the upper plate 2 close to the adaptive side panel 1 is a cylinder, and the cylinder at one end of the upper plate 2 is slidably engaged in the inside of the second limiting groove 11. The adaptive side panel 1, the upper plate 2, the connecting plate 10, and the second limiting groove 11 constitute a sliding pair.

[0026] The present invention further optimizes the structure of the sliding pair by introducing the connecting plate 10 and the second limiting groove 11. The connecting plate 10 is not only fixedly connected to the side wall of the adaptive side panel 1, but is also connected to the upper and lower surfaces of the adaptive side panel 1 via reinforcing ribs. This design significantly enhances the stability and load-bearing capacity of the connecting plate 10.

[0027] The second retaining groove 11 allows the cylindrical end of the upper plate 2 to slide and engage more stably, thus forming a more reliable and efficient sliding pair. This design not only improves the flexibility and adaptability of the structure, but also ensures that the upper plate 2 can slide smoothly under extreme conditions such as earthquakes, effectively absorbing and dissipating seismic energy.

[0028] The optimized design of the sliding pair allows the anti-drop beam device to better adapt to the deformation requirements of the bridge during an earthquake, thereby more effectively protecting the bridge structure from damage. Through the sliding action of the sliding pair, the upper plate 2 can move the damping plate 3 and the anti-buckling plate 5 together, jointly dissipating seismic energy and reducing the seismic response of the bridge structure.

[0029] The introduction of the reinforcement ribs not only enhances the stability of the connecting plate 10, but also improves the overall stability and durability of the entire anti-falling beam device. These reinforcement ribs can effectively resist the effects of external loads and seismic forces, ensuring that the anti-falling beam device maintains stable performance during long-term use. Example 3

[0030] like Figure 3 As shown, an embodiment of the utility model provides an adaptive damping anti-falling beam device, the connection structure includes a fixed roller 12 and a fixed plate 13, the two fixed plates 13 are fixedly connected to the side wall of the adaptive side plate 1 close to the upper plate 2, the fixed roller 12 is fixedly connected to one end of the upper plate 2 close to the adaptive side plate 1, and the two ends of the fixed roller 12 are respectively rotatably connected to the two fixed plates 13.

[0031] By fixing the fixed roller 12 to one end of the upper plate 2 and rotatably connecting it to the two fixed plates 13, this design creates a stable connection point between the upper plate 2 and the adaptive side plate 1. The fixed roller 12 can rotate within a certain range to accommodate slight deformations of the bridge, while providing strong support to ensure a tight connection between the anti-fall beam device and the bridge structure.

[0032] The rotational connection of the fixed rollers 12 allows the upper plate 2 to fine-tune relative to the adaptive side plates 1 under extreme conditions such as earthquakes, thereby absorbing and dissipating seismic energy. This fine-tuning capability helps reduce the seismic response of the bridge structure and protect it from severe damage.

[0033] The combined design of the fixed roller 12 and the fixed plate 13 simplifies installation. Workers can easily install the fixed roller 12 on the upper plate 2 and rotatably connect it to the fixed plate 13. This design also facilitates subsequent maintenance and inspection, as the connection between the fixed roller 12 and the fixed plate 13 is relatively simple, making them easy to disassemble and replace.

[0034] Because the rotating connection of the fixed roller 12 offers a certain degree of flexibility, this design can adapt to the deformation requirements of different bridge structures. Whether it is the longitudinal displacement of the bridge or slight deformation in other directions, the fixed roller 12 can adapt within a certain range, ensuring that the anti-fall beam device always maintains a tight connection with the bridge structure.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
