Description

Technical Field

[0001] This invention belongs to the field of anti-falling beam technology, and more specifically, relates to a self-sensing anti-falling beam device. Background Technology

[0002] Bridge girder collapse is one of the main forms of bridge structural failure under impact loads such as earthquakes. When bridge girder collapse occurs, it often leads to the disruption of vital transportation routes, causing significant damage to life and property. Therefore, to mitigate bridge damage under seismic loads, anti-girder collapse structural measures need to be considered in bridge design.

[0003] In existing technologies, the anti-fall beam devices exert significant restraint on the beam, which to some extent affects the beam's expansion and contraction under normal use conditions. This can further impact the performance of connection nodes, reducing their degree of freedom in expansion and contraction, and potentially causing damage to the anti-fall beam device or the beam itself, thus reducing the device's safety. Furthermore, most existing anti-fall beam devices cannot promptly assess the device's performance and the safety of the bridge connection nodes, thus failing to detect problems or risks in a timely manner. Summary of the Invention

[0004] The purpose of this invention is to provide a self-sensing anti-fall beam device, which aims to solve the technical problems of existing anti-fall beam devices having large constraints on the beam body, being unable to adapt to the expansion and contraction deformation of the beam body under normal use, and being unable to timely assess the safety of the bridge.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a self-sensing anti-falling beam device, comprising:

[0006] The transition steel rods extend from both ends onto the two adjacent sets of beams;

[0007] Two sets of anchoring components are respectively installed at both ends of the transition steel rod and are fixedly connected to the beam.

[0008] A telescopic assembly extends axially along the transition steel rod; the telescopic assembly includes two connecting rods corresponding to the two sets of anchoring assemblies, and a telescopic load-bearing rod disposed between the two connecting rods; both ends of the telescopic load-bearing rod are respectively limited on the corresponding connecting rods by elastic elements, and the telescopic load-bearing rod and the transition steel rod are slidably connected axially along the transition steel rod; and

[0009] Two sets of first strain sensors are symmetrically arranged on the telescopic support rod, one above the other.

[0010] When the beam is displaced or vibrates, the telescopic load-bearing rod compresses the elastic element and slides on the transition steel rod.

[0011] In one possible implementation, limit baffles are provided at both ends of the telescopic support rod;

[0012] A limiting groove is formed on the connecting rod from top to bottom; in the axial direction of the connecting rod, the limiting groove is a stepped groove extending inward from the end of the connecting rod, and the groove size of the stepped groove near the end of the transition steel rod is larger than the groove size of the stepped groove away from the end of the transition steel rod.

[0013] The telescopic support rod passes through the limiting groove, and the limiting baffle is limited at the stepped surface of the limiting groove.

[0014] In some embodiments, the elastic element includes:

[0015] An elastic rubber pad is provided in the limiting groove and is placed at the end of the telescopic support rod and at the bottom of the limiting groove away from the telescopic support rod;

[0016] An elastic rubber ring is fitted onto the telescopic support rod and positioned between the limiting baffle and the stepped surface.

[0017] For example, the transition steel rod is provided with an intermediate barrier, and the telescopic load-bearing rod passes through the intermediate barrier; buffer springs are respectively provided between the intermediate barrier and the opposite ends of the two connecting rods, and the buffer springs are all sleeved on the telescopic load-bearing rod.

[0018] In one possible implementation, the self-sensing anti-falling beam device further includes a limiting ring, which is fixed to a beam column used to support two adjacent sets of beams; a flexible steel rope is connected between the two ends of the telescopic load-bearing rod, and the flexible steel rope passes through the limiting ring.

[0019] In some embodiments, a second strain sensor is provided on the flexible steel rope.

[0020] For example, the flexible steel rope includes a steel wire rope and an epoxy protective layer surrounding the steel wire rope, and two sets of the second strain sensors are symmetrically arranged on the epoxy protective layer along the radial direction of the steel wire rope.

[0021] In one possible implementation, the anchoring component includes:

[0022] An anchor plate is fixed to the corresponding beam; the end of the transition steel rod is fixed to the anchor plate; the connecting rod abuts against the top of the anchor plate.

[0023] An anchor nut is provided on the anchor pad and fixed to the connecting rod;

[0024] An anchoring baffle is disposed on the anchoring pad, parallel to the anchoring nut, and the anchoring baffle abuts against the outer circumferential surface of the connecting rod.

[0025] In some embodiments, the anchoring assembly further includes:

[0026] A spring washer is fitted onto the connecting rod and positioned between the anchoring baffle and the anchoring nut;

[0027] A honeycomb aluminum pad is disposed between the anchoring pad and the transition steel rod; wherein the connecting rod passes through the honeycomb aluminum pad.

[0028] For example, the anchoring baffle includes:

[0029] Multiple sets of vertical rods are distributed at intervals along the axial direction of the connecting rod on both sides of the connecting rod and are fixed to the anchoring plate;

[0030] The cover plate abuts against the top of the connecting rod and is fixed to the plurality of the vertical rods respectively.

[0031] The solution shown in this application, compared with the prior art, ensures the stability of the connection between the two sets of beams and the constraint strength of the beams by setting a transition steel rod between the two sets of beams and fixing the transition steel rod with an anchoring component; by limiting the telescopic load-bearing rod between the two connecting rods, the telescopic load-bearing rod slides on the transition steel rod when the beam is displaced or vibrates, and then the elastic element counteracts the telescopic deformation force generated when the beam is displaced or vibrates, so that the anti-falling beam device adapts to the telescopic deformation of the beam under normal use; by setting a first deformation sensor to monitor the deformation of the beam in real time, and by symmetrically setting two sets of first strain sensors on the telescopic load-bearing rod, the influence of temperature and uneven stress distribution can be reduced, and the accuracy of monitoring the telescopic deformation force of the beam can be improved, so as to timely and accurately assess the safety of the bridge.

Detailed Implementation

[0041] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention 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 merely illustrative of the present invention and are not intended to limit the present invention.

[0042] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0043] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0044] Please refer to the following: Figures 1 to 6 The self-sensing anti-fall beam device provided by the present invention will now be described. The self-sensing anti-fall beam device includes a transition steel rod 1, two sets of anchoring components 2, a telescopic component 3, and two sets of first strain sensors 4; the two ends of the transition steel rod 1 are respectively set on two adjacent sets of beams 5; the two sets of anchoring components 2 are correspondingly set on the two ends of the transition steel rod 1 and fixedly connected to the beams 5; the telescopic component 3 extends along the axial direction of the transition steel rod 1; the telescopic component 3 includes two connecting rods 31 that are connected one-to-one with the two sets of anchoring components 2, and a telescopic load-bearing rod 32 set between the two connecting rods 31; the two ends of the telescopic load-bearing rod 32 are respectively limited on the corresponding connecting rods 31 by elastic elements, and the telescopic load-bearing rod 32 is slidably connected to the transition steel rod 1 along the axial direction of the transition steel rod 1; the two sets of first strain sensors 4 are symmetrically arranged on the telescopic load-bearing rod 32; wherein, when the beam 5 is displaced or vibrates, the telescopic load-bearing rod 32 compresses the elastic element and slides on the transition steel rod 1.

[0045] It is important to understand that the telescopic support rod 32 extends in the same direction as the axial direction of the transition steel rod 1. Specifically, the telescopic support rod 32 extends and retracts along the interval between two adjacent beams 5. When the telescopic support rod 32 slides and retracts on the transition steel rod 1, both ends of the telescopic support rod 32 are always limited to the corresponding connecting rod 31, and the telescopic support rod 32 compresses or stretches the elastic element so that the elastic element can counteract the telescopic deformation caused by the displacement or vibration of the beam 5, thereby ensuring the stability of the beam 5.

[0046] Specifically, please refer to Figure 5 The telescopic support rod 32 has first grooves on its upper and lower sides, suitable for attaching and fixing the first strain sensor 4, and the first grooves extend along the axial direction of the telescopic support rod 32. To eliminate the influence of temperature and external force, specifically, the two first strain sensors 4 are an upper strain gauge and a lower strain gauge. Let the strain value of the upper strain gauge be X1 and the strain value of the lower strain gauge be X2. When both X1 and X2 are positive, the strain value is X = (X1 + X2) / 2. At this time, the stress is relatively uniform and the influence of temperature can be ignored. When X1 and X2 are one positive and one negative, the strain is X = (X1 - X2) / 2. At this time, the stress on the upper strain gauge and the lower strain gauge is opposite, that is, upward pull and downward compression or upward compression and downward pull. X is defined as... T X is the temperature-induced strain. F The strain is caused by external force, at which point X1 = X F +X T X² = X F +X T Therefore, X1-X2 can eliminate the effect of temperature and obtain uniform strain.

[0047] The self-sensing anti-fall beam device provided by this invention, compared with the prior art, ensures the stability of the connection between the two sets of beams 5 and the constraint strength of the beams 5 by setting a transition steel rod 1 between the two sets of beams 5 and fixing the transition steel rod 1 with an anchoring component 2; by limiting the telescopic bearing rod 32 between the two connecting rods 31, the telescopic bearing rod 32 slides on the transition steel rod 1 when the beam 5 is displaced or vibrates, and then the elastic element counteracts the telescopic deformation force generated when the beam 5 is displaced or vibrates, so that the anti-fall beam device can adapt to the telescopic deformation of the beam 5 under normal use; by setting a first deformation sensor to monitor the deformation of the beam 5 in real time, and by symmetrically setting two sets of first strain sensors 4 on the telescopic bearing rod 32, the influence of temperature and uneven stress distribution can be reduced, and the accuracy of monitoring the telescopic deformation force of the beam 5 can be improved, so as to timely and accurately assess the safety of the bridge.

[0048] Please see Figure 3 In some possible embodiments, limit baffles 321 are respectively provided at both ends of the telescopic support rod 32; a limit groove 311 is opened from the top surface downward on the connecting rod 31. In the axial direction of the connecting rod 31, the limit groove 311 is a stepped groove extending inward from the end of the connecting rod 31, and the groove size of the stepped groove near the end of the transition steel rod 1 is larger than the groove size of the stepped groove away from the end of the transition steel rod 1; wherein, the telescopic support rod 32 passes into the limit groove 311, and the limit baffles 321 are limited at the stepped surface of the limit groove 311.

[0049] By setting a limiting baffle 321, a limiting structure is always maintained between the end of the telescopic support rod 32 and the connecting rod 31 to prevent the telescopic support rod 32 from detaching from the connecting rod 31 and affecting the force on the telescopic support rod 32.

[0050] Specifically, the groove near the end of the transition steel rod 1 is defined as the first connecting groove, and the groove away from the end of the transition steel rod 1 is defined as the second connecting groove. The first connecting groove and the second connecting groove form a stepped surface at their junction. The telescopic support rod 32 passes through the second connecting groove into the first connecting groove, and the limiting baffle 321 is always limited within the first connecting groove. Furthermore, the elastic element is also provided in the corresponding first connecting groove.

[0051] Please see Figure 3 In some embodiments, the elastic element includes an elastic pad 33 and an elastic ring 34; the elastic pad 33 is disposed in the limiting groove 311 and is located at the end of the telescopic support rod 32 and at the bottom of the limiting groove 311 away from the telescopic support rod 32; the elastic ring 34 is sleeved on the telescopic support rod 32 and is located between the limiting baffle 321 and the step surface.

[0052] Specifically, the elastic pad 33 is located in the first connecting groove and near the end of the transition steel rod 1. When the telescopic support rod 32 extends or retracts in the first connecting groove, the elastic pad 33 is compressed. Optionally, the elastic pad 33 is a columnar structure extending in the vertical direction. The elastic ring 34 is located in the first connecting groove and between the limiting baffle 321 and the step surface. When the telescopic support rod 32 extends or retracts in the opposite direction in the first connecting groove, the elastic ring 34 is compressed. The elastic pad 33 and the elastic ring 34 can provide a large buffer space for the telescopic support rod 32 and absorb most of the telescopic energy generated when the beam 5 is displaced or vibrates, thereby adapting to the telescopic deformation of the beam 5 when it is displaced or vibrates.

[0053] Please see Figure 2 For example, the transition steel rod 1 is provided with an intermediate barrier 11, and the telescopic support rod 32 passes through the intermediate barrier 11; buffer springs 12 are respectively provided between the opposite ends of the intermediate barrier 11 and the two connecting rods 31, and the buffer springs 12 are all sleeved on the telescopic support rod 32.

[0054] The buffer spring 12 of the present invention is separated by an intermediate barrier 11. When the anti-fall beam device is subjected to tension or compression, the spring can fully exert its energy absorption performance. At this time, regardless of whether the beam 5 is subjected to tension or compression, one of the two buffer springs 12 is deformed under tension and the other under compression, which greatly increases the energy absorption capacity of the two buffer springs 12. At the same time, it can balance the deformation of the buffer springs 12, effectively prevent the buffer springs 12 from reaching their elastic limit, and extend the service life of the buffer springs 12.

[0055] Please see Figure 1 In some possible embodiments, the self-sensing anti-falling beam device also includes a limiting ring 61, which is fixed to the beam column 6 used to support two adjacent sets of beams 5; a flexible steel rope 7 is connected between the two ends of the telescopic load-bearing rod 32, and the flexible steel rope 7 is threaded inside the limiting ring 61.

[0056] By setting up flexible steel ropes 7, an additional layer of protection is added to both ends of the telescopic support rod 32 so that when the beam 5 tilts or leans, the deformation and displacement of the beam 5 are limited by the flexible steel ropes 7, thereby improving the stability of the beam 5 support.

[0057] Please see Figure 6 In some embodiments, a second strain sensor 73 is provided on the flexible steel rope 7. By setting the second strain sensor 73, the expansion and contraction deformation of the beam 5 can be monitored from multiple directions and angles, so as to accurately assess the safety of the beam 5 in a timely manner.

[0058] Please see Figure 6For example, the flexible steel rope 7 includes a steel wire rope 72 and an epoxy protective layer 71 surrounding the steel wire rope 72. Two sets of second strain sensors 73 are symmetrically arranged on the epoxy protective layer 71 along the radial direction of the steel wire rope 72.

[0059] By setting the epoxy protective layer 71, on the one hand, the wear resistance of the flexible steel rope 7 is improved, which can protect the steel wire rope 72 inside the flexible steel rope 7 and prevent the steel wire rope 72 from wearing and breaking during use; on the other hand, it is convenient to open a second groove on the epoxy protective layer 71 so that the second strain sensor 73 can be glued and fixed in the second groove.

[0060] Please see Figure 2 In some possible embodiments, the anchoring assembly 2 includes an anchoring pad 21, an anchoring nut 22, and an anchoring baffle 23; the anchoring pad 21 is fixed to the corresponding beam 5; the end of the transition steel rod 1 is fixed to the anchoring pad 21; the connecting rod 31 abuts against the top of the anchoring pad 21; the anchoring nut 22 is disposed on the anchoring pad 21 and fixed to the connecting rod 31; the anchoring baffle 23 is disposed on the anchoring pad 21 parallel to the anchoring nut 22, and the anchoring baffle 23 abuts against the outer peripheral surface of the connecting rod 31.

[0061] Anchor plate 21 is fixed on beam 5 so that the end of connecting rod 31 is fixed on anchor plate 21 by anchor nut 22 and anchor baffle 23; preferably, the anchor plate 21, anchor nut 22 and anchor baffle 23 are made of stainless steel with galvanized outer layer or 40 chromium material.

[0062] Specifically, the anchor plate 21 has several bolt holes, and bearing-type high-strength bolts are later installed in the bolt holes to fix the anchor plate 21 to the corresponding beam 5.

[0063] Please see Figure 2 In some embodiments, the anchoring assembly 2 further includes a spring washer 24 and a honeycomb aluminum pad 25; the spring washer 24 is sleeved on the connecting rod 31 and placed between the anchoring baffle 23 and the anchoring nut 22; the honeycomb aluminum pad 25 is disposed between the anchoring pad 21 and the transition steel rod 1; wherein the connecting rod 31 passes through the honeycomb aluminum pad 25.

[0064] A spring washer 24 is disposed between the anchoring baffle 23 and the anchoring nut 22. The placement of the spring washer 24 allows for a certain amount of expansion and contraction space between the anchoring baffle 23 and the anchoring nut 22, thereby eliminating the effects of thermal expansion and contraction of the anchoring baffle 23 and the anchoring nut 22.

[0065] The honeycomb aluminum pad 25 has good energy absorption capacity. If an earthquake or other accidental load occurs, the honeycomb aluminum pad can absorb some energy. When the honeycomb aluminum pad 25 absorbs energy and undergoes large deformation, its pad effect fails. At this time, the telescopic load-bearing rod 32 located in the middle has more deformation space, thereby increasing the ductility of the node in case of failure and improving the safety of the node.

[0066] Please see Figure 4 For example, the anchoring baffle 23 includes multiple sets of vertical rods 231 and a cover plate 232; the multiple sets of vertical rods 231 are distributed at intervals along the axial direction of the connecting rod 31 on both sides of the connecting rod 31 and are fixed to the anchoring pad 21; the cover plate 232 abuts against the top of the connecting rod 31 and is fixed to the multiple sets of vertical rods 231 respectively.

[0067] Specifically, the vertical rod 231 is welded and fixed to the anchor plate 21, and the cover plate 232 is connected to the vertical rod 231 by bolts to limit and fix the connecting rod 31, thereby ensuring the stability of the anti-fall beam device.

[0068] The self-sensing anti-fall beam device provided by the present invention is easy to assemble, has reliable stress performance, and can adapt to the expansion and contraction deformation of the beam 5. It has significant tensile and compressive strength and can also sense the stress of the beam 5 through the first strain sensor 4 and the second strain sensor 73. It can effectively ensure the anti-fall beam effect under seismic action and facilitate accurate assessment of the safety of bridge nodes.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
