Description

Technical Field

[0001] The utility model relates to the technical field of early warning structures, in particular to a linkage device and a linkage system for sensing road structure deformation. Background Art

[0002] In recent years, natural disasters have occurred frequently in China. 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 road traffic construction and operation, and even caused major casualties, sounding the alarm for road disaster prevention and mitigation work.

[0003] Currently, existing warning systems often rely on optical and electrical circuit disconnection sensing systems to detect line damage. These systems have strong demands for power and communications. When lines are in an emergency, such as during a mudslide or landslide, there's a high probability of power outages and network outages, which can render these sensing systems ineffective and prevent early warnings. Therefore, there's an urgent need for mechanical sensing devices that can handle extreme situations like power and network outages. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the line break sensing system cannot effectively transmit the line damage situation when the network is disconnected and the power is off, and to provide a linkage device and linkage system for sensing road structure deformation.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] In the first aspect, the utility model provides a linkage device for sensing road structure deformation, comprising a connecting rope arranged along a line, both ends of the connecting rope being fixed ends, at least one end of the connecting rope being used to connect an alarm component, and the relative proximity of the two fixed ends enabling the connecting rope to trigger the corresponding alarm component.

[0007] This linkage device is used to be installed along the line and is applicable to curved lines and straight lines. The device is installed by connecting it to the line structure to be monitored through two fixed ends. The setting length of the connecting rope and the installation position of the two fixed ends are set according to actual needs. For example, for the entire bridge arrangement, the two fixed ends are respectively located at both ends of the bridge (on the bridge or outside the bridge) or one end is located on the bridge and the other end is located outside the bridge. For example, for a section prone to landslides and mud and rock flows, the two fixed ends are respectively located in front and behind the corresponding section. For a longer line, several linkage devices can also be arranged in sections along the line to complete the monitoring and perception of the entire line.

[0008] The fixed end is fixedly connected to the line structure in the initial installation state. The road section that needs to be sensed is located between the two fixed ends. During operation, if the connection with the line structure is disconnected due to external force, the two fixed ends may be relatively close. If the fixed end is connected to the line structure through a connector, the deformation of the connecting cable may cause the connector to be cut, which will cause the two fixed ends to be close. The designed shear force of the two fixed ends can be set differently, so that one end is mainly closer to the other end, thereby judging whether the road structure has displacement and deformation.

[0009] The connecting rope can trigger the alarm component directly or through the transmission component. The structural form of the transmission component and the structural form of the alarm component can both adopt mechanical structural forms (separate application), thereby ensuring that the entire alarm link does not require electricity and communication, thereby improving disaster prevention and mitigation capabilities.

[0010] The present invention employs a linkage device for sensing road structure deformation. Both ends of a connecting cable are fixed, fixing the initial installation length of the connecting cable. At least one end of the connecting cable is connected to an alarm component. When a disaster such as an earthquake, landslide, or mudslide causes damage to a line, the line will deform, causing beams to fall or jump, or the road to tilt or collapse. This significantly deforms the connecting cable, driving the two fixed ends closer together. This changes the distance between the fixed ends of the connecting cable and the corresponding alarm component, triggering an alarm component such as a switch or safety device connected to the alarm device. This device mechanically detects line displacement by installing a connecting cable, sensing line damage and transmitting it to the alarm component, creating a mechanical triggering mechanism. This device effectively responds to emergencies involving highways, bridges, and tunnels, while requiring no power or communications, being less dependent on environmental factors, and exhibiting high stability, reliability, and timeliness. This improves line disaster monitoring and early warning capabilities, scientifically guiding vehicles to avoid danger, and minimizing disaster losses and casualties.

[0011] Preferably, the fixed end includes a first anchor plate, an anchor head and a connecting plate, the first anchor plate is connected to the connecting plate, and a second anchor plate is provided between the anchor head and the first anchor plate for connecting one end of the warning component, and an elastic component is provided between the second anchor plate and the first anchor plate, and in the initial state, the elastic component is in a compressed state.

[0012] The connecting plate is used for fixed connection with main beams, roadbed, etc.

[0013] At least one of the fixed ends is in the form of an elastic component, and the second anchor plate moves toward the first anchor plate to make the two fixed ends relatively close to each other, so that the two fixed ends can be relatively close to each other under a certain force.

[0014] The first anchor plate is used to limit the anchor head. By adding an elastic component between the anchor head and the first anchor plate, the elastic component is in a compressed state in the initial state. The elastic force of the elastic component is effectively utilized to keep the connecting rope in a tensioned or straight state, thereby improving the perception accuracy of deformation caused by disasters and reducing false alarms. At the same time, the deformation ability of the elastic component can better adapt to the temperature deformation and creep of the line structure, avoid the breakage of the connecting rope, effectively extend the service life of the device, and improve the applicability of the device.

[0015] Further preferably, the elastic component is a spring, and the spring is sleeved on the connecting rope.

[0016] Further preferably, a sleeve is provided on the outer side of the spring, the sleeve is retractable, and two ends of the sleeve are respectively connected to the first anchor plate and the second anchor plate.

[0017] The sleeve is provided to guide the deformation of the spring. The sleeve can be a bellows compensator, a sleeve compensator, etc.

[0018] Further preferably, the sleeve comprises an inner sleeve and an outer sleeve, and the inner sleeve and the outer sleeve are connected in a longitudinal sliding manner along the sleeve.

[0019] Preferably, the fixed end is replaced by a tensioning end.

[0020] That is, a tensioning machine is used as the fixed end. If a jack is provided, it is convenient to tension the connecting cable during installation, and it is also convenient to re-tension the connecting cable, thereby ensuring the long-term effectiveness of the device.

[0021] Further preferably, the connecting rope is a plurality of steel strands.

[0022] Further preferably, a plurality of limiting members are provided at intervals along the longitudinal direction of the connecting cable, and the limiting members are used to limit the installation position of the connecting cable in the lateral and vertical directions, and the connecting cable can move relative to the limiting members.

[0023] The limiter is connected to the line structure to be installed like the fixed end, and is used to limit the horizontal and vertical positions of the connecting cable, which is beneficial for straightening the connecting cable during installation, so as to better sense the deformation of the line structure and facilitate tensioning.

[0024] Further preferably, the linkage device is arranged on the main beam, guardrail, roadbed, shoulder or inner wall of the tunnel.

[0025] When used in bridge structures, they can be set on the side, bottom, guardrail, etc. of the main beam; when used in road structures, they can be set on the roadbed, guardrail, hard shoulder, etc.; when used in tunnel structures, they can be set on the side wall, arch, etc. of the tunnel.

[0026] The utility model also provides a kind of linkage system of knowing road structure deformation, comprising two as described above one kind of linkage device of knowing road structure deformation, the position of the elastic component of two linkage devices is set to different sides.

[0044] Example 1

[0045] The utility model adopts a linkage device for sensing road structure deformation, which includes a connecting rope 1. The connecting rope 1 is arranged along the line. Both ends of the connecting rope 1 are fixed ends. At least one end of the connecting rope 1 is used to connect to an alarm component. The relative proximity of the two fixed ends can enable the connecting rope 1 to trigger the corresponding alarm component.

[0046] The fixed end is fixedly connected to the line structure in the initial installation state, such as by connecting the fixed end to the line structure through embedded parts or other structures.

[0047] In some embodiments, the two ends of the connecting cable 1 are not limited to being located at the two ends of the line. For example, for a bridge structure, both ends of the connecting cable 1 can be set on the same side of the same span, such as anchoring from one side of the beam span to the other side; or, for a tunnel structure, it can be arranged horizontally along the tunnel to monitor cross-sectional damage, that is, the road section to be sensed is located between the two fixed ends as needed.

[0048] In some embodiments, the fixed end comprises a first anchor plate 21, an anchor head 23 and a connecting plate 24, wherein the first anchor plate 21 is connected to the connecting plate 24, and the structures of the two fixed ends are the same, such as Figure 1 As shown, the connecting plate 24 is used to connect the line structure. For example, by means of shear nails, the shear force of the shear nails can be determined according to the design requirements, so that when the force exceeds the preset force, that is, in the event of a natural disaster, it can be cut off, thereby triggering the alarm component.

[0049] In some embodiments, if it is necessary to adapt to temperature deformation, strip-shaped holes may be provided so that the connecting rope 1 can adapt to deformation in some normal operation links.

[0050] In some embodiments, the first anchor plate 21 may be connected to a plurality of stiffening ribs.

[0051] In some embodiments, one of the fixed ends can be replaced with a tensioning end, such as Figure 1 The left side of the middle connecting cable 1 is connected to the warning component, and the fixed end on the right side is replaced by the tensioning end, that is, an anchor and a jack are set.

[0052] In some embodiments, the connecting rope 1 is a plurality of steel strands, and other rope structures that can meet the force requirements can also be selected.

[0053] In some embodiments, a plurality of limiting members 5 are provided at longitudinal intervals along the connecting cable 1 . The limiting members 5 are used to limit the installation position of the connecting cable 1 in the lateral and vertical directions. The connecting cable 1 can move relative to the limiting members 5 .

[0054] In some embodiments, the limiting member 5 may include a connecting plate, on which structures such as rings, hooks, and clips are provided. The spacing of the limiting members 5 is set according to actual needs.

[0055] In some embodiments, the line structure may be a main beam, a guardrail, a roadbed, a shoulder, or an inner wall of a tunnel.

[0056] When used in bridge structures, they can be set on the side, bottom, guardrail, etc. of the main beam; when used in road structures, they can be set on the roadbed, guardrail, hard shoulder, etc.; when used in tunnel structures, they can be set on the side wall, arch, etc. of the tunnel.

[0057] In some embodiments, a second anchor plate 22 is further provided between the anchor head 23 and the first anchor plate 21 for connecting one end of the warning component, and an elastic component 3 is provided between the second anchor plate 22 and the first anchor plate 21. In the initial state, the elastic component 3 is in a compressed state, and the second anchor plate 22 approaches the first anchor plate 21, thereby causing the two fixed ends to be relatively close, such as Figure 2 As shown, the structures of the two fixed ends are the same, that is, both ends of the connecting rope 1 are connected with warning components.

[0058] Since the second anchor plate 22 is not connected to the corresponding connecting plate 24, the displacement and deformation of the connecting cable 1 can cause the anchor head 23 on the corresponding side to drive the second anchor plate 22 to move toward the first anchor plate 21, thereby triggering the alarm component.

[0059] The first anchor plate 21 is used to limit the anchor head 23. By adding an elastic component 3 between the anchor head 23 and the first anchor plate 21, the elastic force of the elastic component 3 is used to keep the connecting rope 1 in a tensioned or straight state, thereby improving the perception accuracy of deformation caused by disasters. At the same time, the deformation ability of the elastic component 3 can better adapt to the temperature deformation and creep of the line structure, thereby avoiding the breakage of the connecting rope 1, effectively extending the service life of the device, and improving the applicability of the device.

[0060] In some embodiments, the elastic component 3 is a spring, which is sleeved on the connecting cable 1 and can also be circumferentially arranged around the connecting cable 1 .

[0061] In some embodiments, a sleeve 4 is provided on the outside of the spring. The sleeve 4 is retractable, and two ends of the sleeve 4 are respectively connected to the first anchor plate 21 and the second anchor plate 22 .

[0062] In some embodiments, the sleeve 4 includes an inner sleeve 41 and an outer sleeve 42 , and the inner sleeve 41 and the outer sleeve 42 are connected in a longitudinal sliding manner of the sleeve 4 to allow the sleeve 4 to extend and retract.

[0063] In some embodiments, the fixed end can be replaced with a tensioning end, such as Figure 2 The left side of the middle connecting cable 1 is connected to the warning component, and the fixed end on the right side is replaced by the tensioning end, that is, a jack and anchor are set, and the left side can also be replaced by the tensioning end.

[0064] In some embodiments, the connecting cable 1 can be connected to the plug-in switch of the alarm component. When the connecting cable 1 is displaced and deformed, the plug-in switch is driven to move and then turned on, thereby triggering the alarm component to alarm.

[0065] In some embodiments, the warning components may include banners, foam barriers, etc., with warning slogans such as "Road blocked ahead, emergency vehicle pickup" written on the banners. Taking into account the use scenarios where there is a lack of light such as at night or in tunnels, the warning slogans on the banners may be made of reflective materials. The banners are usually stored in a box body, which is hung high on a bridge or roadbed. A box cover is provided at the bottom of the box body and is locked by a box body switch. The movement of the plug-in switch can open the box body switch and allow the banner to fall from the box body and unfold to issue a warning. The box body switch may use a pin shaft or a lock buckle, for example. The pin shaft is plugged into the box body and the box cover, or the lock buckle locks the box body and the box cover. The initial plug-in direction of the pin shaft or the locking direction of the lock buckle is opposite to the direction of movement of the connecting rope 1.

[0066] Both ends of the connecting cable 1 are fixed, securing the initial installation length of the connecting cable 1. At least one end of the connecting cable 1 is connected to an alarm component. When a disaster such as an earthquake, landslide, or mudslide damages the line, the line will deform, causing beams to fall or jump, or the road to tilt or collapse. This will cause the connecting cable 1 to deform significantly, driving the two fixed ends closer together. This changes the distance between the fixed ends of the connecting cable 1 and the corresponding alarm component, triggering an alarm in the alarm component, such as a switch or safety device connected to the alarm device. This device mechanically detects line displacement by installing a section of connecting cable 1, thereby sensing line damage and transmitting it to the alarm component, creating a mechanical triggering mechanism. This device can effectively respond to disaster emergencies such as highways, bridges, and tunnels, while requiring no power or communications, being less dependent on environmental factors, and possessing high stability, reliability, and timeliness. This improves the line's disaster monitoring and early warning capabilities, scientifically guiding vehicles to avoid danger, and minimizing disaster losses and casualties.

[0067] Example 2

[0068] The present invention adopts a linkage device for sensing road structure deformation, and its structure is roughly the same as that of embodiment 1, except that the structures of the two fixed ends are different, such as Figure 3 As shown, Figure 3 The fixed end on the left side has an elastic component 3, and the fixed end on the right side is a common anchoring form, so that the shear forces that can be borne by the two ends are different. The left side of the connecting rope 1 is connected to the warning component.

[0069] In some embodiments, Figure 3 The fixed ends on the right and / or left sides of the center are replaced by tensioned ends.

[0070] The damage, deformation and displacement of the line may cause the connecting cable 1 to deform and trigger the alarm component, such as Figure 4 shown.

[0071] Example 3

[0072] The utility model adopts a linkage system for sensing road structure deformation, which includes two linkage devices for sensing road structure deformation as in Example 2. The elastic components 3 of the two linkage devices are arranged on opposite sides, such as Figure 5 As shown, the structural forms of the fixed ends on the same side are different. Of course, the fixed ends of the ordinary anchoring form can be replaced by tensioning ends.

[0073] In some embodiments, the two linkage devices are located on both sides of the line, that is, one linkage device is provided on one side.

[0074] In some embodiments, a linkage system may be provided on each side of the line.

[0075] The linkage device for sensing road structure deformation is used for bidirectional driving, two linkage devices are combined for use, and the end of the linkage device connected with the warning device is located in different directions, so that two oncoming vehicles can be warned, and the two linkage devices can be arranged on the same side of the line or different sides of the line

[0076] The above are only preferred embodiments of the utility model, and are not used to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
