Description

Technical Field

[0001] The invention relates to the technical field of bridge warning, and in particular to bridge damage emergency warning equipment, a composite warning system and a bridge. Background Art

[0002] In recent years, natural disasters have occurred frequently, and geological disasters such as mountain torrents, mud and rock flows, falling rocks, and landslides have seriously threatened the safety of people's lives and property in highway transportation construction and operation.

[0003] Existing warning devices for bridge damage or collapse are mostly sound and light warning devices. However, the sound and light warning devices need to be electrically connected or signal connected to the travel switch. However, when the bridge is damaged or collapsed, there will be power outages and network disconnections, so that the sound and light warning devices cannot be activated and cannot issue warnings. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing bridge warning devices in the prior art, which mostly only use sound and light equipment to alarm. If the bridge collapses, the sound and light warning devices may not be activated and no warning can be issued. The present invention provides bridge damage emergency warning equipment, a composite warning system and a bridge.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] In a first aspect, the present invention provides a bridge damage emergency warning system, comprising:

[0007] A linkage device, the linkage device is used to transmit the displacement of the main beam, the linkage device comprises a sensor cable, the sensor cable comprises at least one A end, and the displacement of the main beam can drive the A end to move;

[0008] A mechanical warning device, wherein the mechanical warning device comprises a trigger rope and a warning member, wherein the warning member is arranged above the driving lane, wherein both ends of the trigger rope are respectively connected to the A end and the warning member, and movement of the A end drives movement of the trigger rope, and movement of the trigger rope causes the warning member to fall.

[0009] The A end of the sensor cable is the end that can be driven to move when the main beam is displaced. When both ends of the sensor cable are A ends, the two A ends can be connected to different trigger ropes. The sensor cable can be set on the guardrail of the bridge, on the bridge deck, or connected to the side of the main beam. The two ends of the sensor cable can be set on the guardrail of the bridge, on the bridge deck, on the bridge piers, or on the roads or tunnels at both ends of the bridge. The warning member can be a rigid folding member, a flexible member, or an inflatable member. The warning member is set above the carriageway, either directly above or diagonally above.

[0010] When the main beam is displaced, it drives end A to move; the displacement of end A drives the displacement of the trigger rope, and the displacement of the trigger rope causes the warning piece to fall and issue a warning. Compared with the prior art that only warns through sound and light alarm suction devices, this device uses the linkage reaction of mechanical devices to warn, rather than through electrical connections or signal connections. This can avoid as much as possible the situation where the warning device is invalid due to network or power outages caused by bridge collapse, and can minimize the number of vehicles driving into damaged or collapsed main beams, which is beneficial to protecting the lives and property safety of pedestrians.

[0011] Preferably, the sensing cable is a prestressed steel bundle, the axis of the sensing cable is arranged along the direction of the bridge, and both ends of the sensing cable are anchored at both ends of the bridge respectively.

[0012] The axis of the sensor cable is parallel to the longitudinal direction of the bridge. The sensor cable is a tensioned sensor cable. Therefore, when the main beam is damaged or collapsed, the displacement of the main beam is avoided as much as possible to drive the displacement of the A end. Instead, the displacement of the main beam is made to drive the displacement of the A end as much as possible, which is beneficial to improving the sensitivity of the linkage device and protecting the lives and property safety of pedestrians.

[0013] Preferably, it also includes a first spring and an anchor head, the A end is connected to the anchor head, the first spring is sleeved on the sensor cable, an anchor plate and a fixing plate are respectively provided at both ends of the first spring, the fixing plate can be fixed to the main beam, the anchor head abuts against the anchor plate, the movement of the A end drives the movement of the anchor head, and the movement of the anchor head can drive the anchor plate to approach or move away from the fixing plate along the length direction of the first spring.

[0014] The first spring is mounted on the sensor cable, and a fixed plate and a movable anchor plate are respectively provided at both ends of the first spring. The fixed plate can be fixed on the main beam, and the anchor head abuts against the anchor plate. When end A is anchored by the anchor head, it can also move along the length direction of the sensor cable. When the main beam is displaced, the anchor head moves toward the other end of the sensor cable. The first spring is provided so that when the first spring is under pressure, a force can be applied to end A to move away from the other end of the sensor cable. The first spring also has a fixed plate, which can limit the maximum displacement of end A, and avoid the situation where end A is displaced too much and damages the mechanical warning device as much as possible, which is beneficial to improving the service life of the device.

[0015] Preferably, the two ends of the trigger rope are respectively connected to the A end and the weight block, or the two ends of the trigger rope are respectively connected to the A end and the second spring, and one end of the second spring is fixed.

[0016] The provision of a weight block or a second spring can provide a force to the anchor head away from the other end of the sensor cable, resisting the shortening of the sensor cable as much as possible, so that the trigger rope remains stationary in the initial state where the A end has not been displaced.

[0017] Preferably, it further comprises a sensing device, the trigger rope is connected to the A end through the sensing device, the movement of the A end drives the movement of the sensing device, and the movement of the sensing device drives the movement of the trigger rope.

[0018] The trigger rope is connected to the A end through the induction device, which makes it difficult for the device to be blocked and fail.

[0019] Preferably, the sensing device comprises a latch, one end of which is connected to the A end, the trigger rope knot loop is placed outside the latch, the movement of the A end drives the latch to move and detach from the trigger rope, and the latch detaches from the trigger rope so that the trigger rope is displaced;

[0020] or,

[0021] The sensing device comprises a rotating shaft and a transmission roller, wherein the transmission roller is wrapped around the rotating shaft and connected to the A end and the trigger rope. The movement of the A end drives the transmission roller to swing along the rotating shaft, and the swing of the transmission roller drives the trigger rope to move.

[0022] The latch can move along its axis. The trigger rope knot loop is placed outside the latch, and the latch limits the displacement of the trigger rope; the movement of end A drives the latch to break away from the trigger rope, and the trigger rope is no longer restricted by the latch, and moves, opening the accommodating device, and the warning piece falls.

[0023] The rotating shaft can be arranged in the middle of the transmission roller, or at one end of the transmission roller. When the rotating shaft can be arranged in the middle of the transmission roller, the A end and the trigger rope can be arranged on both sides of the rotating shaft, or on one side of the rotating shaft. The swing of the transmission roller drives the trigger rope to move, and the displacement of the trigger rope causes the container to open and the warning member to fall.

[0024] Preferably, the sensing device is connected to the A end via an adjustment rope, and the length of the adjustment rope is greater than the maximum distance from the sensing device to the A end.

[0025] When the sensing device includes a latch, the two ends of the adjustment rope are connected to the latch and end A respectively; when the sensing device includes a rotating shaft and a transmission roller, the two ends of the adjustment rope are connected to the transmission roller and end A respectively. The length of the adjustment rope is determined according to the actual situation. If the length of the adjustment rope is greater than the maximum distance from the sensing device to end A, then in the initial state where end A is not displaced, the adjustment rope is in a relaxed state. Then, when the sensing rope is slightly deformed due to temperature or other factors, the adjustment rope can buffer the slight deformation, avoid displacement of the trigger rope, and thus avoid triggering the mechanical warning device, reduce false alarms, and help improve the warning accuracy of the warning device.

[0026] Preferably, it further comprises a plurality of fixing rings, which are spaced apart and distributed on the main beam along the longitudinal direction of the bridge, and are used for limiting the position of the sensor cable.

[0027] The fixing ring can be a clamp or a sliding guide tube. The fixing ring fixes the sensor cable, which can limit the sensor cable to slide only along its axial direction, preventing the sensor cable from detaching from the main beam, thereby causing a false alarm or a situation where an alarm is required but not issued, which is conducive to improving the alarm accuracy of the alarm device.

[0028] Preferably, the two ends of the sensor cable can also be replaced by two B ends, and the two B ends are arranged at the two ends of the bridge through reaction seats, the trigger rope is connected to the B end, and the end of the trigger rope away from the B end is connected to a weight-bearing piece or a second spring, and the displacement of the main beam can drive the reaction seat to separate from the bridge. The reaction seat separates from the bridge so that the B end can be moved by the displacement of the main beam, and the movement of the B end drives the trigger rope to move, and the movement of the trigger rope causes the warning piece to fall.

[0029] The B end of the sensor cable is fixed to the end of the main beam through the reaction seat. Because the movement of the main beam will provide shear force to the reaction seat through the sensor cable, and the sensor cable has excellent tensile strength, the reaction seat will detach from the main beam before the sensor cable is broken. When the reaction seat detaches from the main beam, the B end will move with the displacement of the bridge, so it can drive the trigger rope to move, causing the warning piece to fall.

[0030] In a second aspect, the present invention provides a composite warning system, comprising a bridge damage emergency warning system as described above, and also comprising an audible and visual warning device, wherein the displacement of the main beam drives the movement of the sensor cable, and the movement of the sensor cable causes the audible and visual warning device to connect and issue a warning.

[0031] When the sensor cable includes at least one A end, the movement of the A end causes the sound and light warning device to be connected and an alarm is issued; when both ends of the sensor cable are B ends, the reaction seat separates from the main beam so that the B end is displaced by the displacement of the main beam, and the movement of the B end drives the trigger rope to move, and the movement of the trigger rope causes the sound and light warning device to be connected and an alarm is issued.

[0032] The composite warning device also includes an audible and visual warning device, which can combine audible and visual warnings with mechanical warnings to warn more vehicles and enable vehicles that are far away from the mechanical warning device to receive warnings, thereby avoiding rear-end collisions with the vehicle in front as much as possible, which is beneficial to protecting life and property safety.

[0033] Preferably, it also includes an acoustic and optical travel switch, the contacts of which are connected to a sensing device, the movement of the sensing cable drives the sensing device to be displaced, the displacement of the sensing device drives the contact to be displaced, the displacement of the contact turns on the acoustic and optical travel switch, and the sound and optical travel switch is turned on so that the acoustic and optical warning device is connected to a circuit.

[0034] When the sensing cable includes at least one A end, the movement of the A end drives the contact to move; when both ends of the sensing cable are B ends, the displacement of the B end drives the contact to move.

[0035] When the contact rebounds to turn on the sound and light travel switch, in the initial state when the main beam is not damaged or collapsed, the latch or transmission roller presses on the contact, causing the sound and light travel switch to be disconnected, and the sensor cable moves to drive the latch or transmission roller away from the contact, and the sound and light travel switch is turned on; when the contact is compressed to turn on the sound and light travel switch, in the initial state when the main beam is not damaged or collapsed, the latch or transmission roller does not contact the contact, and the sensor cable moves to drive the latch or transmission roller close to the contact and compress the contact, and the sound and light travel switch is turned on.

[0036] In a third aspect, the present invention provides a bridge, comprising a bridge damage emergency warning system as described above, or comprising a composite warning system as described above.

[0037] A bridge includes the above-mentioned bridge damage emergency warning system or a composite warning system, which can issue a mechanical warning when the main beam is displaced, thereby minimizing the number of vehicles driving into the damaged or collapsed main beam, thereby protecting the lives and property of pedestrians.

[0038] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

A bridge damage emergency warning system, comprising a linkage device and a mechanical warning device, wherein the linkage device comprises a sensor cable, the sensor cable comprises at least one end A, the mechanical warning device comprises a trigger rope and a warning piece, the two ends of the trigger rope are respectively connected to the sensor cable and the accommodating device, and the warning piece is arranged above the carriageway, and when the main beam is displaced, the end A can be driven to move, and the movement of the end A drives the trigger rope to be displaced, and the displacement of the trigger rope causes the warning piece to fall. Compared with the prior art which only warns through an acoustic and visual alarm suction device, this device uses a linkage reaction of a mechanical device to warn, rather than through an electrical connection or a signal connection, so as to avoid as much as possible the situation where the warning device is invalid due to bridge collapse, and can reduce as much as possible the number of vehicles driving into damaged or collapsed main beams, which is beneficial to protecting the lives and property of pedestrians. This device overcomes the shortcomings of the prior art that most bridge warning devices only use acoustic and optical equipment for alarming, and if the bridge collapses, the acoustic and visual warning device cannot be activated and cannot issue a warning.

[0040] 2. A composite warning system includes the above-mentioned bridge damage emergency warning system and also includes an audible and visual warning device. When the main beam is displaced, the sensor cable is driven to move, which enables the audible and visual warning device to be connected and issue a warning.

[0063] Example 1

[0064] like Figures 1 to 14 As shown, a bridge damage emergency warning system adopted in this embodiment includes:

[0065] A linkage device, the linkage device is used to transmit the displacement of the main beam 10, the linkage device comprises a sensor cable 1, the sensor cable 1 comprises at least one A end, and the displacement of the main beam 10 can drive the A end to move;

[0066] A mechanical warning device comprises a trigger rope 5 and a warning member 8. The warning member 8 is arranged above the driving lane. Both ends of the trigger rope 5 are respectively connected to the A end and the warning member 8. The movement of the A end drives the trigger rope 5 to move. The movement of the trigger rope 5 causes the warning member 8 to fall.

[0067] The A end of the sensor cable 1 is the end that can be driven to move when the main beam 10 is displaced. The sensor cable 1 can be set on the guardrail of the bridge, can be set on the bridge deck, and can also be connected to the side of the main beam 10. The two ends of the sensor cable 1 can be set on the guardrail of the bridge, can be set on the bridge deck, can be set on the bridge pier, and can also be set on the road or tunnel 63 at both ends of the bridge, and this embodiment is not limited. When the main beam 10 is displaced, it drives the A end to move; the displacement of the A end drives the displacement of the trigger rope 5, and the displacement of the trigger rope 5 causes the warning member 8 to fall and issue a warning. Compared with the prior art that only warns through the sound and light alarm suction device, this device uses the linkage reaction of a mechanical device to warn, rather than through electrical connection or electrical connection to transmit signals, so as to avoid the situation where the warning device is invalid due to network disconnection or power outage due to bridge collapse, and can reduce the number of vehicles driving into the damaged or collapsed main beam 10 as much as possible, which is beneficial to protecting the life and property safety of pedestrians.

[0068] Furthermore, the sensor cable 1 is a prestressed steel bundle, the axis of the sensor cable 1 is arranged along the bridge direction, and the two ends of the sensor cable 1 are respectively anchored at the two ends of the bridge 10. Both ends of the sensor cable 1 are provided with reaction seats 33, the A end is anchored by the anchor head 12 and the anchor pad 22, and the B end is anchored by the anchor head 12 and the working anchor plate 3.

[0069] Furthermore, if Figure 2As shown, in this embodiment, one end of the sensor cable 1 is end A, and the other end is end B. End A includes a first spring 2, and the first spring 2 is sheathed on the sensor cable 1. An anchor plate 22 and a fixing plate 23 are respectively provided at both ends of the first spring 2. The fixing plate 23 can be fixed to the main beam 10, and the anchor head 12 abuts against the anchor plate 22. The anchor head 12 can drive the anchor plate 22 to approach or move away from the fixing plate 23 along the length direction of the first spring 2. The axis of the sensor cable 1 is parallel to the longitudinal direction of the bridge, and the sensor cable 1 is a tensioned sensor cable 1. When the main beam 10 is damaged or collapsed, the displacement of the main beam 10 is avoided as much as possible to drive the deformation of the sensor cable 1, but the displacement of the main beam 10 drives the displacement of end A as much as possible, which is conducive to improving the sensitivity of the linkage device and protecting the life and property safety of pedestrians. A first limiter 21 is provided outside the first spring 2. In this embodiment, the first limiter 21 includes an inner sleeve and an outer sleeve. The outer sleeve is slidably connected to the inner sleeve, and the inner wall of the outer sleeve is connected to the outer wall of the inner sleeve. The inner sleeve and the outer sleeve are provided to avoid displacement of the end A not along the axial direction of the sensor cable 1 when the end A moves, which is beneficial to improve the accuracy of the device. In this embodiment, one end of the outer sleeve is connected to the anchor plate 22, and one end of the inner sleeve is connected to the fixed plate 23. In actual use, one end of the inner sleeve can also be connected to the anchor plate 22, and one end of the outer sleeve can be connected to the fixed plate 23. This embodiment is not limited.

[0070] Furthermore, if Figure 10-Figure 14 As shown, the two ends of the trigger rope 5 are respectively connected to the A end and the weight block 52, or the two ends of the trigger rope 5 are respectively connected to the A end and, and one end of the second spring 53 is fixed. When the weight block 52 is set, as shown in FIG. Fig.10 As shown, a third stopper 54 needs to be provided in the predetermined falling area of ​​the ballast block 52 to prevent the ballast block 52 from falling into the driving lane and affecting the driving safety of the vehicle.

[0071] Furthermore, it also includes a sensing device, and the trigger rope 5 is connected to the A end through the sensing device. The movement of the A end drives the movement of the sensing device, and the movement of the sensing device drives the movement of the trigger rope 5.

[0072] The same plan Figure 6-Figure 8As shown, the sensing device includes a latch 41, one end of which is connected to the A end, and the trigger rope 5 is looped and sleeved on the latch 41. The movement of the A end drives the latch 41 to move and detach from the trigger rope 5. The latch 41 detaches from the trigger rope 5 so that the trigger rope 5 is displaced. The latch 41 is fixed by a fixing frame 413. A first steering pulley 411 is provided above the fixing frame 413, and the first steering pulley 411 is installed on a supporting frame 412. The trigger rope 5 passes through the supporting frame 412 and bypasses the first steering pulley 411 to be looped on the latch 41. A locking piece 414 is provided on the latch 41 for fixing the latch 41 to the supporting frame 412. As shown Figure 8 As shown, the movement of end A drives the latch 41 to disengage from the fixing frame 413, and the locking member 414 disengages from the latch 41, so that the trigger rope 5 moves toward the warning member 8. To ensure that the trigger rope 5 can cause the warning member 8 to fall, in the initial state where the main beam 10 does not move, the weight block 52 connected to the trigger rope 5 is off the ground or the second spring 53 is in a stretched state, and the falling of the weight block 52 or the rebound of the second spring 53 drives the trigger rope 5 to move. Figure 6 The arrow is the displacement trend direction of the trigger rope 5.

[0073] Option 2 Fig. 9 As shown, the sensing device includes a rotating shaft 42 and a transmission roller 421. The transmission roller 421 is coated with the rotating shaft 42. The transmission roller 421 is connected to the A end and the trigger rope 5. The movement of the A end drives the transmission roller 421 to swing along the rotating shaft 42. The swing of the transmission roller 421 drives the trigger rope 5 to move. In this embodiment, the distance from the trigger rope 5 to the rotating shaft 42 is greater than the distance from the adjustment rope 43 to the rotating shaft 42. The transmission roller 421 can amplify the displacement of the A end, which is beneficial to improve the sensitivity of the device. In actual use, the transmission roller 421 and the adjustment rope 43 can be respectively set on both sides of the rotating shaft 42, or as shown in FIG. Fig. 9 The transmission roller 421 is also connected to a reset spring 422, so that the transmission roller 421 can be reset after being driven by the sensor cable 1 to rotate.

[0074] like Figure 6 and Fig. 9 As shown, the sensing device is connected to the A end through an adjustment rope 43, and the length of the adjustment rope 43 is greater than the maximum distance between the sensing device and the A end. The length of the adjustment rope 43 is greater than the maximum distance between the sensing device and the A end, and the adjustment rope 43 is in a relaxed state in the initial state where the A end is not displaced. When the sensing rope 1 is slightly deformed due to temperature or other factors, the adjustment rope 43 can buffer the slight deformation, avoid displacement of the trigger rope 5, and thus avoid triggering the mechanical warning device, reduce false alarms, and help improve the warning accuracy of the warning device.

[0075] Furthermore, it also includes a plurality of fixing rings 11, which are spaced apart on the main beam 10 along the longitudinal direction of the bridge, and the fixing rings 11 are used to limit the position of the sensor cable 1. The fixing ring 11 can be a clamp or a sliding guide. The fixing ring 11 fixes the sensor cable 1, which can limit the sensor cable 1 to slide only along its axial direction, and prevent the sensor cable 1 from detaching from the main beam 10, thereby causing a false alarm or a situation where an alarm is required but not issued, which is conducive to improving the alarm accuracy of the alarm device.

[0076] In actual use, both ends of the sensor cable 1 can be in the form of A ends. If a two-way lane is provided, a mechanical warning device can be provided at each end of the main beam 10, and the two mechanical warning devices are connected to the two A ends respectively.

[0077] Furthermore, the mechanical warning device further comprises a second diverting pulley 51 and a receiving device 7. The second diverting pulley 51 is used to change the direction of the trigger rope 5, and the receiving device 7 is used to receive the warning member 8. Figure 10-Figure 14 As shown, the accommodating device 7 is rotatably connected to a baffle 71 that can be opened and closed, and the baffle 71 is fixed to the accommodating device 7 by a switch 72. The movement of the trigger rope 5 drives the pin of the switch to move, so that the baffle 71 opens and the warning member 8 falls. The warning member 8 can be a soft warning flag, and the warning surface of the warning flag faces the direction of the driving lane; it can also be a plastic warning plate that is arranged at intervals and can be folded, and several plastic warning plates are connected by a hanging rope 81 so that they can be folded, and a counterweight 81 is connected under the hanging rope 81 to enable the plastic warning plate to fall smoothly; it can also be an airbag, wherein the airbag is in an uncompressed state when stored in the accommodating device 7, the baffle 71 opens, the airbag inflates and falls, and a warning is issued. The principle of the airbag is the same as that of the safety airbag of a car. In actual use, the warning member 8 can be made in the form of a faucet, and the movement of the trigger rope 5 causes the faucet to open and spray water to issue a warning. When the mechanical warning device is arranged inside the tunnel 63, such as Figure 10-12 As shown, the accommodating device 7 is hoisted on the top of the tunnel 63, and a steel hanger 62 and an anti-falling steel rope 621 are provided as required; when the mechanical warning device is provided outside the tunnel 63, as shown in FIG. Figure 13-14 As shown, a gantry 61 is also provided to hoist the accommodating device 7.

[0078] In actual use, the device can also be used to warn of road damage.

[0079] Example 2

[0080] like Figure 5As shown, a bridge damage emergency warning system has substantially the same structure and embodiments, except that: the two ends of the sensor cable 1 can also be replaced by two B ends, and the two B ends are both arranged at the two ends of the bridge 10 through a reaction seat 33, and the trigger rope 5 is connected to the B end, and the end of the trigger rope 5 away from the B end is connected to a weight-bearing member or a second spring 53, and the displacement of the main beam 10 can drive the reaction seat 33 to detach from the bridge 10, and the detachment of the reaction seat 33 from the bridge 10 allows the B end to be moved by the displacement of the main beam 10, and the movement of the B end drives the trigger rope 5 to move, and the movement of the trigger rope 5 causes the warning member 8 to fall.

[0081] The B end of the sensor cable 1 is fixed to the end of the main beam 10 through the reaction seat 33. Because the movement of the main beam 10 will provide shear force to the reaction seat 33 through the sensor cable 1, and the sensor cable 1 has excellent tensile strength, the reaction seat 33 will be separated from the main beam 10 before the sensor cable 1 is broken. When the reaction seat 33 is separated from the main beam 10, the B end will move with the displacement of the bridge, so it can drive the trigger rope 5 to move, thereby causing the warning member 8 to fall.

[0082] Example 3

[0083] A composite warning system includes a bridge damage emergency warning system as described in Example 1 or Example 2, and further includes an acoustic and visual warning device, wherein the displacement of the main beam 10 drives the sensor cable 1 to move, and the movement of the sensor cable 1 causes the acoustic and visual warning device to connect and issue a warning. The distribution of the acoustic and visual warning device is determined according to actual conditions.

[0084] It also includes an acoustic and optical travel switch 9, the contacts of which are connected to a sensing device. The movement of the sensing cable 1 drives the sensing device to be displaced, and the displacement of the sensing device drives the contacts to be displaced. The displacement of the contacts turns on the acoustic and optical travel switch 9, and the sound and light travel switch 9 is turned on so that the acoustic and optical warning device is connected to a circuit.

[0085] When the sensing cable 1 includes at least one A end, the movement of the A end drives the contact 91 to move; when both ends of the sensing cable 1 are B ends, the displacement of the B end drives the contact 91 to move.

[0086] When the contact 91 rebounds to connect the sound and light travel switch 9, in the initial state when the main beam 10 is not damaged or collapsed, the latch 41 or the transmission roller 421 presses on the contact 91, so that the sound and light travel switch 9 is disconnected, and the sensor cable 1 moves to drive the latch 41 or the transmission roller 421 away from the contact 91, and the sound and light travel switch 9 is connected; when the contact 91 is compressed to connect the sound and light travel switch 9, in the initial state when the main beam 10 is not damaged or collapsed, the latch 41 or the transmission roller 421 does not contact the contact 91, and the sensor cable 1 moves to drive the latch 41 or the transmission roller 421 close to the contact 91 and compress the contact 91, and the sound and light travel switch 9 is connected.

[0087] In this embodiment, Figure 6-Figure 9 As shown, the contact 91 rebounds and connects the sound and light travel switch 9. When the sensing device includes a latch 41, in the initial state where the main beam 10 does not move, the contact 91 is compressed by the latch 41; when the latch 41 is driven by the sensor cable 1 to separate from the fixed frame 413, the contact 9 rebounds; when the sensing device includes a rotating shaft 42 and a transmission roller 421, in the initial state where the main beam 10 does not move, the contact 91 is compressed by the transmission roller 421; when the transmission roller 421 is driven by the sensor cable 1 to swing away from the fixed frame 413, the contact 9 rebounds. In actual use, the position of the sound and light travel switch 9 is determined according to actual conditions.

[0088] Example 4

[0089] A bridge includes a bridge damage emergency warning system as described in Example 1 or Example 2, or includes a composite warning system as described in Example 3, which can issue a mechanical warning when the main beam 10 is displaced, thereby minimizing the number of vehicles driving into the damaged or collapsed main beam 10, thereby protecting the lives and property of pedestrians.

[0090] The above are only preferred embodiments of the present invention and are 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 in the protection scope of the present invention.
