[0049] Example 1
[0050] like Figures 1 to 3 As shown, the bridge and roadbed displacement sensing activation device described in the utility model includes a fixed component 1, a movable component 2, an elastic member 3, a sensing rope 4, an adjustment rope 5, a plug-in trigger component 6, a first rope 7, a guide component 8 and an acousto-optic travel switch 9.
[0051] For example, Figure 1 and Figure 3As shown, the movable component 2 is arranged between the fixed component 1 and the plug-in trigger component 6, the elastic member 3 is connected between the movable component 2 and the fixed component 1, and the sensing rope 4 passes through the fixed component 1 and is anchored to the movable component 2; wherein, the fixed component 1 includes a fixed plate 11, a first sleeve 12 and a stiffening plate 13, and the movable component 2 includes a movable plate 21, a second sleeve 22 and an anchor 23; the stiffening plate 13 is connected to the fixed plate 11, and the stiffening plate 13 and the fixed plate 11 are connected to a bridge or a roadbed, the first sleeve 12 is connected to the fixed plate 11, and the first sleeve 12 is directed toward the movable component The component 2 is provided, the stiffening plate 13 is provided away from the movable component 2, the elastic member 3 is provided in the first sleeve 12, the second sleeve 22 is connected to the movable plate 21, the second sleeve 22 is slidably connected to the first sleeve 12, the elastic member 3 is provided in the second sleeve 22, and the two ends of the elastic member 3 are respectively abutted on the fixed plate 11 and the movable plate 21; the anchor 23 is connected to the sensing rope 4 and anchored on the movable plate 21, the sensing rope 4 is provided along the length direction of the bridge or roadbed, the sensing rope 4 is configured to be in a straightened state, and the sensing rope 4 is used to deform with the displacement of the bridge or roadbed. With this structure, by providing the fixed component 1, the movable component 2 and the elastic member 3 as the connecting structure of the movable end of the sensing rope 4, appropriate prestress can be applied to the sensing rope 4, making it easy for the sensing rope 4 to be straightened.
[0052] For example, Figures 1 to 3 As shown, the plug-in trigger assembly 6 includes a first support 61, a latch 62 and a limit pin 63. The first support 61 is connected to the bridge or roadbed, and the latch 62 is plugged into the first support 61. The latch 62 is connected to the anchor 23 through the adjustment rope 5. The adjustment rope 5 is configured to be in a relaxed state. The limit pin 63 is provided on the latch 62, and the limit pin 63 is set away from the adjustment rope 5. The limit pin 63 is used to limit the relative position of the latch 62 and the first support 61 to prevent the latch 62 from falling off easily. With this structure, in some cases where non-disasters cause large deformation and displacement of the bridge or roadbed, such as temperature deformation or deformation caused by vehicle collision, the end of the sensing rope 4 will still be displaced, and these non-disaster deformations can be adapted to by setting the relaxed adjustment rope 5.
[0053] For example, Figures 1 to 3As shown, one end of the first rope 7 is sleeved on the pin 62, and the other end is connected to the counterweight after passing through the guide assembly 8. The movement of the first rope 7 can activate the switch of the alarm device; the guide assembly 8 is used to change the direction of the first rope 7. The guide assembly 8 includes a third support 81 and a pulley group 82. The third support 81 is connected to the bridge or roadbed. The pulley group 82 is provided on the third support 81.

With this structure, the sound and light limit switch 9 is integrated with the mechanical activation device. When the latch 62 is pulled out, the restriction on the contact rod 91 is released, and the contact rod 91 pops out and extends. The sound and light limit switch 9 activates the remote sound and light warning device, which works together with the warning device released by the mechanical structure to improve the warning effect.
[0055] In an optional embodiment, the fixing plate 11 , the stiffening plate 13 , the first support 61 , and the third support 81 are all connected to a base, and the base is connected to a bridge or a roadbed.
[0056] In an optional embodiment, the fixed component 1, the movable component 2, the elastic member 3, the plug-in trigger component 6, and the guide component 8 are all made of steel structure, the sensing rope 4 is made of steel wire rope, and the adjustment rope 5 and the first rope 7 are both made of nylon rope or steel wire rope.
[0057] In an optional embodiment, the warning device can be a banner with warning slogans such as "Road blocked ahead, emergency vehicle pickup" written on the banner. 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 banner can be made of reflective material. The banner is usually stored in a box body, and the box body is hung high on a bridge or roadbed. A box cover is set at the bottom of the box body and connected through a box body switch. The first rope 7 is connected to the box body switch. The movement of the first rope 7 can open the box body switch to open the box cover, and the banner falls from the box body and unfolds to issue a warning; the box body switch uses a pin shaft or a lock buckle, and 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 in which the first rope 7 can move. Therefore, the movement of the first rope 7 can drive the pin shaft or the lock buckle to release the connection between the box body and the box cover.
[0058] When a disaster occurs, the bridge or roadbed undergoes large deformation and damage, causing the sensing rope 4 to be pulled. The movable end of the sensing rope 4 compresses the elastic member 3, straightens the adjusting rope 5, and pulls the pin 62 in the plug-in trigger assembly 6 out of the first support 61 through the adjusting rope 5. The pin 62 is pulled out of the loop of the first rope 7, that is, the first rope 7 is unlocked. Under the action of the counterweight, the first rope 7 is configured to be pulled and moved. During the movement, the first rope 7 pulls the switch of the alarm device, so that the alarm device is activated.
[0059] The present embodiment describes a bridge and roadbed displacement sensing activation device. When a disaster occurs, causing the bridge or roadbed to be severely deformed and damaged and unable to operate, the displacement deformation of the bridge or roadbed pulls the sensing rope 4 to deform; the end of the sensing rope 4 pulls out the latch 62 to unlock the first rope 7, and the first rope 7 moves under the action of the counterweight, unlocking the alarm device during the movement. The plug-in trigger assembly 6 and the first rope 7 cooperate sensitively and quickly, and are not prone to jamming and failure. The alarm device is quickly unlocked by the above-mentioned mechanical activation device, which does not rely on electricity and communication, has a good effect, and is conducive to promotion.
[0060] Example 2
[0061] like Figure 4 As shown, the bridge and roadbed displacement sensing activation device described in the present invention includes a fixed component 1, a movable component 2, an elastic member 3, a sensing rope 4, an adjustment rope 5, a rocker-type trigger component, a second rope 104 and an acousto-optic travel switch 9.
[0062] For example, Figure 4As shown, the movable component 2 is arranged between the fixed component 1 and the rocker trigger component, the elastic member 3 is connected between the movable component 2 and the fixed component 1, and the sensing rope 4 passes through the fixed component 1 and is anchored to the movable component 2; wherein, the fixed component 1 includes a fixed plate 11, a first sleeve 12 and a stiffening plate 13, and the movable component 2 includes a movable plate 21, a second sleeve 22 and an anchor 23; the stiffening plate 13 is connected to the fixed plate 11, and the stiffening plate 13 and the fixed plate 11 are connected to the bridge or roadbed, the first sleeve 12 is connected to the fixed plate 11, and the first sleeve 12 is directed toward the movable component The movable assembly 2 is provided with a stiffening plate 13, the stiffening plate 13 is provided away from the movable assembly 2, the elastic member 3 is provided in the first sleeve 12, the second sleeve 22 is connected to the movable plate 21, the second sleeve 22 is slidably connected to the first sleeve 12, the elastic member 3 is provided in the second sleeve 22, and the two ends of the elastic member 3 are respectively abutted against the fixed plate 11 and the movable plate 21; the anchor 23 is connected to the sensing rope 4 and anchored to the movable plate 21, the sensing rope 4 is provided along the length direction of the bridge or roadbed, the sensing rope 4 is configured to be in a straightened state, and the sensing rope 4 is used to deform with the displacement of the bridge or roadbed. With this structure, by providing the fixed assembly 1, the movable assembly 2 and the elastic member 3 as the connecting structure of the movable end of the sensing rope 4, appropriate prestress can be applied to the sensing rope 4, making it easy to straighten the sensing rope 4.
[0063] For example, Figure 4 As shown, the rocker-type trigger assembly includes a second support 101, a transmission roller 102, and a rotating shaft 103. The second support 101 is connected to the bridge or roadbed, and the transmission roller 102 is hinged to the second support 101 via the rotating shaft 103. The anchor 23 is connected to the adjustment rope 5. The sensing rope 4 is connected to the end of the transmission roller 102 near the hinge point via the adjustment rope 5, and the adjustment rope 5 is configured to be in a relaxed state. The second rope 104 is connected to the end of the transmission roller 102 away from the hinge point. The movement of the second rope 104 can activate the alarm device. With this structure, in some non-disaster-induced large deformation and displacement of the bridge or roadbed, such as deformation caused by temperature or vehicle impact, the end of the sensing rope 4 will still move. The relaxed adjustment rope 5 can accommodate these non-disaster deformations.
[0064] For example, Figure 4As shown, the sound and light travel switch 9 includes a contact rod 91; the rocker-type trigger assembly also includes a return spring 105, which is connected to the transmission roller 102. The return spring 105 and the sound and light travel switch 9 are both located on the side away from the sensing rope 4. The return spring 105 pulls the transmission roller 102 against the contact rod 91. With this structure, the sound and light travel switch 9 is integrated with the mechanical activation device. When the transmission roller 102 is pulled, the restriction on the contact rod 91 is released, and the contact rod 91 is ejected and extended. The sound and light travel switch 9 activates the remotely installed sound and light warning device, which works together with the warning device released by the mechanical structure to enhance the warning effect.
[0065] In an optional embodiment, the fixing plate 11 , the stiffening plate 13 , and the second support 101 are all connected to a base, and the base is connected to a bridge or a roadbed.
[0066] In an optional embodiment, the fixed component 1, the movable component 2, the elastic member 3, and the rocker trigger component are all made of steel structure, the sensing rope 4 is made of steel strand, and the adjustment rope 5 and the second rope 104 are both made of nylon rope or steel wire rope.
[0067] In an optional embodiment, the warning device can be a banner with warning slogans such as "Road blocked ahead, emergency vehicle pickup" written on the banner. 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 banner can be made of reflective material. The banner is usually stored in a box body, which is hung high on a bridge or roadbed. A box lid is set at the bottom of the box body and is connected through a box body switch. The second rope 104 is connected to the box body switch. The movement of the second rope 104 can open the box body switch to open the box lid, and the banner falls from the box body and unfolds to issue a warning; the box body switch uses a pin shaft or a lock, for example. The pin shaft is plugged into the box body and the box lid, or the lock locks the box body and the box lid. The initial plugging direction of the pin shaft or the locking direction of the lock buckle is the same as the direction in which the second rope 104 can move. Therefore, the movement of the second rope 104 can drive the pin shaft or the lock buckle to release the connection between the box body and the box lid.
[0068] When a disaster occurs, the bridge or roadbed undergoes large deformation and damage, causing the sensing rope 4 to be pulled. The movable end of the sensing rope 4 compresses the elastic member 3, straightens the adjusting rope 5, and pulls the transmission roller 102 through the adjusting rope 5 to rotate close to the fixed component 1. The transmission roller 102 rotates and pulls the second rope 104 to move. During the movement, the second rope 104 pulls the switch of the alarm device, so that the alarm device is activated.
[0069] The present embodiment describes a bridge and roadbed displacement sensing activation device. When a disaster occurs, causing the bridge or roadbed to be severely deformed and damaged and unable to operate, the displacement deformation of the bridge or roadbed pulls the sensing rope 4 to deform; the end of the sensing rope 4 pulls the transmission roller 102 to rotate, and the transmission roller 102 pulls the second rope 104 to move, unlocking the alarm device during the movement. The displacement of the end of the sensing rope 4 is amplified by the force arm of the transmission roller 102, so that the second rope 104 moves sensitively and is not easily blocked and fails; the alarm device is quickly unlocked by the above-mentioned mechanical activation device, which does not rely on electricity and communication, has a good effect, and is conducive to promotion.
[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
