Description

Technical Field

[0001] This application relates to the field of warning devices, and more particularly to a linkage-type beam detachment warning device. Background Technology

[0002] As a vital infrastructure connecting complex terrain, the safety of bridges is of paramount importance. In environments prone to natural disasters, sudden events such as mudslides, landslides, and rockfalls can pose significant risks to the supporting surfaces of bridges.

[0003] Existing bridges typically consist of supporting piers and bearing surfaces, with the bearing surfaces also serving as crossbeams. When the bearing surfaces are joined between two adjacent piers, natural disasters such as rockfalls and mudslides can easily impact them, causing lateral displacement, tearing, or detachment.

[0004] In order to provide timely warnings and handling of accident sites, most bridge safety monitoring systems on the market rely on power supply, sensor networks, and remote data transmission. These methods are costly and complex to maintain, and there are risks in response to adverse environments such as power outages and network interruptions. Using these methods on small bridges in remote mountainous areas results in high costs. Such high-cost, high-tech-intensive solutions are difficult to promote on a large scale and operate in the long term.

[0005] Therefore, how to design a simple and fast-responding beam detachment warning device has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This application provides a linkage-type crossbeam detachment warning device to at least solve the above-mentioned technical problems existing in the prior art.

[0007] A linkage-type crossbeam detachment warning device is provided, comprising at least two sets of warning components, each including a support plate, a warning sign, a folding arm, and a locking mechanism. The support plate is fixedly installed on the bridge support pier and / or bearing surface. One end of the folding arm is rotatably connected to the support plate, and the other end of the folding arm is rotatably connected to the warning sign. It also includes a power mechanism that provides power for the folding arm to switch from the folded state to the unfolded state. The locking mechanism is installed between two adjacent warning pieces and is inserted into the support plate to keep the folding arm in the folded state. The locking pin mechanism is located on one side of the bridge bearing surface and is used to receive the displacement changes of the bearing surface so that the locking pin mechanism can disengage from the support plate and release the restriction on the folding arm.

[0008] In one embodiment, the folding arm includes a first extension arm and a second extension arm. The first end of the first extension arm is rotatably connected to a support plate, and the second end of the first extension arm is rotatably connected to the first end of the second extension arm via a first pivot. The second end of the second extension arm is rotatably connected to a warning sign. When the folding arm is unfolded, the first extension arm is in a horizontal state, and the second extension arm is in a vertically upward extending state.

[0009] In one embodiment, a lifting lug is fixedly provided on the support plate, and the first extension arm is rotatably connected to the lifting lug through a second rotating shaft. The power mechanism includes a first torsion spring, which is sleeved on the outside of the second rotating shaft. One end of the first torsion spring is fixedly connected to the lifting lug, and the other end of the first torsion spring is fixedly connected to the first extension arm.

[0010] In one embodiment, the power mechanism includes a second torsion spring, which is sleeved on the outside of the first rotating shaft. One end of the second torsion spring is fixedly connected to the first extension arm, and the other end of the second torsion spring is fixedly connected to the second extension arm.

[0011] In one embodiment, the second extension arm is provided with a plug hole arranged along the axial direction of the second extension arm, and a rotating rod is fixedly provided on the warning sign. The rotating rod is inserted into the plug hole, and the outer wall of the rotating rod is rotatably connected to the inner wall of the plug hole. The power mechanism includes a third torsion spring, which is sleeved on the outside of the rotating rod. One end of the third torsion spring is fixedly connected to the warning sign, and the other end of the third torsion spring is fixedly connected to the second extension arm.

[0012] In one embodiment, the second extension arm is provided with a limiting groove communicating with the insertion hole. The cross-section of the limiting groove is fan-shaped. A limiting block extending to the limiting groove is fixed on the rotating rod. The side wall of the limiting block abuts against the inner wall of the limiting groove to limit the angle of rotation of the rotating rod.

[0013] In one embodiment, the first extension arm is made of C-shaped steel, and in the folded state of the folding arm, the second extension arm is located in the slot of the first extension arm.

[0014] In one embodiment, it further includes two limiting plates, which are fixedly installed on the support plate and located below the lifting lug. The limiting plates are provided with pin holes, and the locking mechanism includes a locking pin, which is inserted into the pin hole and abuts against the folding arm to lock the folding arm between the two limiting plates.

[0015] In one embodiment, the locking mechanism further includes a traction rope, the two ends of which are fixedly connected to the locking pins on both sides. The traction rope is located on one side of the bridge bearing surface and is used to receive the displacement changes of the bearing surface.

[0016] In one possible implementation, the system also includes a warning light, which has a power supply gap for powering on or off, and a blocking card. The blocking card is fixedly connected to the bridge support pier or bearing surface by a pull rope. When the blocking card is inserted into the power supply gap, the warning light is de-energized and the blocking card is removed from the power supply gap. When the warning light is energized and the folding arm is unfolded, the blocking card is removed from the power supply gap.

[0017] Compared with the prior art, the linkage-type crossbeam detachment warning device of this application has the following beneficial effects: This application utilizes a locking pin mechanism to restrict the folding arm to a folded state, thereby enabling the storage of the warning sign. When the bridge's bearing surface shifts due to a sudden event, it comes into contact with the locking pin mechanism, causing the locking pin mechanism to detach from the support plate. At this time, the locking pin mechanism releases the restriction on the folding arm, and the power mechanism provides power to the folding arm to switch it from the folded state to the unfolded state, thereby changing the position of the warning sign so that pedestrians can promptly observe the warning signs on the side of the bridge, reducing the risk of safety accidents. Compared with existing technologies that use power supply and sensor network data transmission, this application has lower cost, simpler structure, reduces interference from external factors, improves alarm response speed, and is convenient for trial implementation in remote mountainous areas.

[0022] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in 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, and 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.

[0023] like Figure 1 As shown, the warning device includes at least two sets of warning elements 1, wherein the warning elements 1 are distributed along one side of the bridge's length direction, and the warning elements 1 can be fixedly installed on the bridge's supporting piers or bearing surface. A locking pin mechanism 14 is installed between two adjacent warning elements 1, wherein the locking pin mechanism 14 is located on one side of the bearing surface, and the locking pin mechanism 14 is used to monitor changes in the position of the bridge's bearing surface, thereby controlling the warning elements 1 to perform early warning processing.

[0024] Specifically, in this embodiment, two warning elements 1 are used as examples for description, such as... Figure 2 As shown, the warning component 1 includes a support plate 11, a warning sign 12, and a folding arm 13. The two ends of the folding arm 13 are rotatably connected to the support plate 11 and the warning sign 12, respectively. The folding arm 13 can switch between a folded state and an unfolded state. When the folding arm 13 is in the folded state, as shown... Figure 1 and Figure 2 As shown, the folding arm 13 is attached to one side of the support plate 11 and extends longitudinally. When the folding arm 13 is in the unfolded state, as... Figure 3 As shown, at this time, the warning sign 12 is located on the side away from the bridge, extending the warning sign 12 to a conspicuous position so that passers-by can observe it and serve the purpose of warning.

[0025] Specifically, when the folding arm 13 is in a folded state, the locking pin mechanism 14 is inserted into the corresponding support plate 11 to restrict the folding arm 13 and prevent it from unfolding.

[0026] The support plate 11 is fixedly installed on the bridge support pier or bearing surface by means of screws and expansion nuts.

[0027] like Figure 2 and Figure 3 As shown, the folding arm 13 includes a first extension arm 131 and a second extension arm 132. The first end of the first extension arm 131 is rotatably connected to the support plate 11. The second end of the first extension arm 131 and the first end of the second extension arm 132 are rotatably connected through a first rotating shaft 133. The second end of the second extension arm 132 is rotatably connected to the warning sign 12. The folding arm 13 also includes a power mechanism 2, which provides the folding arm 13 with the driving force to switch from the folded state to the unfolded state.

[0028] Specifically, the power mechanism 2 includes a first torsion spring 21, a second torsion spring 22, and a third torsion spring 23. One end of the first torsion spring 21 is fixedly connected to the first extension arm 131, and the other end of the first torsion spring 21 is fixedly connected to the support plate 11. One end of the second torsion spring 22 is fixedly connected to the first extension arm 131, and the other end of the second torsion spring 22 is fixedly connected to the second extension arm 132. One end of the third torsion spring 23 is fixedly connected to the second extension arm 132, and the other end of the third torsion spring 23 is fixedly connected to the warning sign 12. The first torsion spring 21 provides power for the relative rotation of the folding arm 13 and the support plate 11, the second torsion spring 22 provides power for the relative rotation of the first extension arm 131 and the second extension arm 132, and the third torsion spring 23 provides power for the relative rotation of the warning sign 12 and the second extension arm 132.

[0029] Specifically, such as Figure 4 As shown, a lifting lug 111 is fixedly provided on the support plate 11, wherein the first extension arm 131 is rotatably connected to the lifting lug 111 via a second rotating shaft 134; the support plate 11 is also provided with a limiting plate 112 located below the lifting lug 111, wherein two limiting plates 112 are provided, and the limiting plates 112 are provided with pin holes 1121, such that when the folding arm 13 is in the folded state, as Figure 1 and Figure 2 As shown, the folding arm 13 is located between the two limiting plates 112, and the locking pin mechanism 14 is inserted into the corresponding pin hole 1121, thereby restricting the folding arm 13 from rotating around the second rotating shaft 134 and preventing the folding arm 13 from being unfolded.

[0030] Specifically, the locking mechanism 14 includes a locking pin 141 and a traction rope 142. The two ends of the traction rope 142 are fixedly connected to the locking pins 141 on both sides. The locking pins 141 are inserted into the pin holes 1121. The first torsion spring 21 provides the folding arm 13 with the force to open. At this time, the folding arm 13 transmits the force to the locking pin 141, thereby shearing the locking pin 141.

[0031] The traction rope 142 between the two locking pins 141 is taut to receive the pushing force applied by the bearing surface. After the bearing surface collides with the traction rope 142, the pulling force provided by the traction rope 142 to the locking pin 141 causes the locking pin 141 to disengage from the pin hole 1121.

[0032] In order to achieve relative rotation between the warning sign 12 and the second extension arm 132, in this embodiment, as follows: Figure 5 As shown, the second extension arm 132 is provided with a plug hole 1321 arranged along the axial direction of the second extension arm 132. A rotating rod 121 is fixedly provided on the warning sign 12. The rotating rod 121 is inserted into the plug hole 1321. The outer wall of the rotating rod 121 is rotatably connected to the inner wall of the plug hole 1321. A third torsion spring 23 is sleeved on the outside of the rotating rod 121. One end of the third torsion spring 23 is fixedly connected to the warning sign 12, and the other end of the third torsion spring 23 is fixedly connected to the second extension arm 132.

[0033] In order to control the twist angle of the warning sign 12 after it is unfolded, in this embodiment, as follows: Figure 7 As shown, the second extension arm 132 is also provided with a limiting groove 1322 that communicates with the insertion hole 1321. The cross-section of the limiting groove 1322 is fan-shaped. The side wall of the rotating rod 121 is fixedly provided with a limiting block 1211 that extends to the limiting groove 1322. The side wall of the limiting block 1211 abuts against the inner wall of the limiting groove 1322, thereby limiting the rotation angle of the rotating rod 121.

[0034] When warning element 1 is deployed, in order to provide a more obvious warning to pedestrians, in this embodiment, as follows: Figure 2 and Figure 6 As shown, it also includes a warning light 3 fixedly installed on the warning sign 12. The warning light 3 is provided with a power supply gap 31 for turning the power on and off. It also includes a blocking card 4. When the blocking card 4 is inserted into the power supply gap 31, the warning light 3 is in an off state. When the blocking card 4 is removed from the power supply gap 31, the warning light 3 is lit to increase the warning effect.

[0035] Specifically, the blocking card 4 is connected to the supporting pier or bearing surface of the bridge via a pull rope. When the warning element 1 is in a folded state, the blocking card 4 is inserted into the power supply gap 31 and the pull rope is taut. When the warning element 1 is unfolded, the blocking card 4 is pulled out of the power supply gap 31 by the force provided by the pull rope.

[0036] Specifically, the first extension arm 131 is made of a C-shaped steel channel. When the folding arm 13 is folded, the second extension arm 132 is stored in the slot of the first extension arm 131.

[0037] With the above configuration, multiple warning elements 1 are provided and distributed along the length of the bridge. A locking pin mechanism 14 locks the folding arm 13 between adjacent warning elements 1, thereby causing the folding arm 13 to be in a folded position. Figure 1 In the folded state, the traction rope 142 of the locking mechanism 14 is taut, and the folding arm 13 applies a thrust to the locking pin 141 so that the locking pin 141 and the pin hole 1121 generate a shearing force to prevent the folding arm 13 from unfolding unnecessarily.

[0038] When the bridge's supporting surface is affected by a natural disaster, its position shifts. At this time, the supporting surface pushes against the traction rope 142, causing the traction rope 142 to deform and push the locking pin 141 out of the pin hole 1121. The locking pin 141 then releases its lock on the folding arm 13, and the first torsion spring 21 causes the first extension arm 131 to rotate ninety degrees to a horizontal position. Figure 3 As shown, at this time, the second torsion spring 22 drives the second extension arm 132 to rotate around the first rotating shaft 133, so that the first extension arm 131 and the second extension arm 132 rotate relative to each other, thereby keeping the second extension arm 132 in a vertically upward extending state, which can drive the warning sign 12 beyond the horizontal plane of the bridge to play a warning role. At the same time, the third torsion spring 23 drives the warning sign 12 to twist, so that the sign face of the warning sign 12 faces the direction of travel, so that pedestrians can see it. At this time, the pull rope pulls out the blocking card 4, and the warning light 3 lights up to warn pedestrians that there is a failure in this section of the bearing surface, so as to avoid unnecessary safety accidents.

[0039] It is worth noting that the folding arm 13 can be folded. When the first extension arm 131 of the folding arm 13 is in a vertical position, the second extension arm 132 can be folded into the slot of the first extension arm 131. At this time, the warning sign 12 is rotated at a certain angle, and the warning surface of the warning sign 12 faces the bridge, so as to avoid the warning surface being exposed to the outside and reduce the damage of the external environment to the warning surface.

[0040] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
