Example (b):
fig. 1 to 4 show schematic structural views of a bridge height-limiting anti-collision device according to a first embodiment of the present application, where the bridge height-limiting anti-collision device specifically includes: including limit for height steel pipe 1 and a plurality of being used for fixing limit for height steel pipe 1's buffering fixed knot constructs 2, limit for height steel pipe 1 transversely sets up along the outside of 3 lower edges of bridge, buffering fixed knot constructs 2 and includes screw rod 21, spring 22 and nut 23, screw rod 21's first end fixed connection bridge 3, other end axial pass spring 22, radially pass limit for height steel pipe 1 and pass through nut 23 is fixed and is locked.
Specifically, in the embodiment of the present application, the height-limiting steel pipe 1 is fixed by the screw 21 of each buffer fixing structure 2, and the height-limiting steel pipe 1 is utilized to provide a good anti-collision effect. It can be understood that, since the height-limiting steel pipe 1 is disposed outside the lower edge of the overpass 3, that is, when the bridge 3 is impacted by a ship or a traveling crane, the height-limiting steel pipe 1 is generally in direct contact with the bridge. The height-limiting steel pipe 1 is of a hollow tubular structure, and when the height-limiting steel pipe 1 is impacted, the impacted part is stressed to generate elastic-plastic deformation so as to resist the impact force of ships or traveling cranes and avoid the situation that the main body of the bridge 3 directly bears the impact force to cause bridge damage and the like.
In one embodiment, the height-limiting steel pipe 1 is coated with a rubber pad on the outer side. The energy dissipation effect of the energy of the force leakage of the height limiting steel pipe 1 can be further optimized through the rubber pad, so that a better anti-collision effect is achieved. And, the rubber pad has also protected limit for height steel pipe 1 to a certain extent, avoids it to receive the striking and excessively warp. It can be understood that the bending deformation damage of the height-limiting steel pipe 1 can be avoided due to the energy consumption of the rubber pad to the force leakage of the impact. For some light impacts, a better protection of the height-limiting steel pipe 1 is provided. Further reducing the maintenance cost of the anti-collision measures. In some embodiments, the height-limiting steel pipe 1 may employ related warning settings to indicate the height limitation of the ship or the crane bridge. Wherein, can set up limit for height steel pipe 1 surface into red, red limit for height steel pipe 1 can provide obvious warning effect to the height restriction of bridge is known directly perceivedly to boats and ships or driving. Furthermore, in some embodiments, the rubber pad may be replaced with other cushioning materials such as sponge and the like. The embodiment of the application does not make fixed restrictions on which material is used to coat the height-limiting steel pipe 1, and is not described herein.
Further, referring to fig. 1, in order to provide a better anti-collision effect, a spring 22 is disposed at the right side of the height-limiting steel pipe 1, and the deformation orientation of the spring 22 is defined by a screw 21 passing through the spring 22. It can be understood that, normally, the spring 22 is in a free state, and when the height-limiting steel pipe 1 is impacted, the impact force acts on the height-limiting steel pipe 1, and the height-limiting steel pipe 1 abuts against the spring 22, so that the spring 22 is compressed and deformed. The impact force can be further resisted through the compression deformation of the spring 22, and a better anti-collision effect is provided on the basis of the height-limiting steel pipe 1.
In one embodiment, the spring 22 may be replaced by an elastic rubber or the like, which is inserted into the screw 21 and is pressed and fixed by the height-limiting steel tube 1. Similarly, when the height-limiting steel pipe 1 is impacted, the impact force acts on the height-limiting steel pipe 1, the elastic rubber is compressed by the height-limiting steel pipe 1, and the impact force is resisted through the elastic deformation of the elastic rubber.
In the embodiment of the present application, one end (i.e., the first end) of the screw 21 is fixedly connected to the bridge, and the other end (i.e., the second end) axially passes through the spring 22, radially passes through the height-limiting steel pipe 1, and is fixedly locked by the nut 23. Therefore, the buffer fixing structure 2 can buffer and fix the height-limiting steel pipe 1. Wherein, the screw 21 and the nut 23 provide a supporting and fixing effect, and the spring 22 provides a buffering and releasing effect. Specifically, the first end of the screw 21 is fixedly connected to the outer side of the lower edge of the bridge. As shown in FIG. 1, the first end of the screw 21 is inserted into the bridge body, the spring 22 and the height-limiting steel tube 1 are sequentially sleeved at the second end, and finally the nut 23 is screwed down, so that a better supporting effect of the screw 21 is realized. In some embodiments, the first end of the screw 21 may also be fixedly connected to the bridge in other fixing connection manners, specifically, the effect of supporting and fixing the screw 21 is achieved, and the embodiment of the present application is not limited to fixing.
Further, according to actual anticollision setting needs, this application embodiment can set up the buffering fixed knot that corresponds quantity constructs 2. The buffer fixing structures 2 are arranged along the axial direction of the height-limiting steel pipe 1 at even intervals. By arranging the buffering fixing structures 2 at even intervals, the springs 22 of the buffering fixing structures 2 can provide balanced buffering and force-releasing effects for the height-limited steel pipes 1. In addition, set up buffering fixed knot through even interval and construct 2, can provide good support fixed effect to limit for height steel pipe 1. In some embodiments, the buffer fixing structure 2 may also be disposed corresponding to two side positions of each navigation channel or lane. For example, the buffer fixing structure 2 is provided at a position corresponding to both sides of each of six lanes outside the lower edge of the bridge corresponding to an upper-span bridge of the six lanes. It can be understood that, when a bridge collision occurs, the buffering fixing structures arranged on the two sides of the corresponding lane can provide better anti-collision effect, so that the springs 22 of the buffering fixing structures 2 can exert optimal force-leakage buffering effect. And simultaneously, the risk that the vehicle and the ship directly impact the screw of the buffering fixed structure 2 is avoided very much.
More specifically, in this application embodiment, bridge limit for height buffer stop can provide the effect of three-layer leakage force buffering. When a vehicle or a ship with an over-limit height running under a bridge firstly impacts the height-limiting steel pipe 1, the impact contact part of the height-limiting steel pipe 1 generates elastic-plastic deformation, and the first-layer stress relief buffering is realized through impact energy consumption; further, under the action of impact force, the height-limited steel pipe 1 is bent and deformed, and the second-layer stress relief buffering is realized through the second-stage impact energy consumption; and then, the impact force received by the height-limiting steel pipe 1 is transmitted to the spring 22, the spring 22 is compressed and deformed, and the third-level impact energy consumption is used for realizing the third-level stress relief buffering. Finally, through the three-level energy consumption, the driving kinetic energy of the vehicle and the ship with the height below the bridge exceeding the limit is obviously reduced, and finally, the impact force transmitted to the bridge through the spring 22 is also obviously reduced, so that the damage of the impact on the bridge structure and the vehicle and the ship is obviously reduced.
In one embodiment, the buffer fixing structure 2 further includes a pressure sensor for acquiring pressure information of the buffer fixing structure 2, and the pressure sensor is in signal connection with the system background and is used for uploading the pressure information to the system background. Referring to fig. 5, the buffer fixing structures 2 corresponding to the bridge height limiting and collision preventing devices are provided with a corresponding number of pressure sensors, and the pressure sensors are used for determining the impact force generated when the current height exceeds the limit vehicle and ship and impacts the bridge by acquiring the pressure information of the buffer fixing structures 2. Further, the pressure information is uploaded to a system background, and the system background can judge whether the bridge collision condition occurs currently according to the pressure information. As shown in fig. 5, the pressure sensor of the bridge height-limiting anti-collision device corresponding to each bridge is connected with the system background signal, so as to form a bridge height-limiting anti-collision alarm and positioning system. It can be understood that when the pressure information sent by the pressure sensor of a certain bridge indicates that the impact force of the bridge exceeds the standard, it can be determined that the corresponding bridge has an impact condition. In order to distinguish different bridges, different numbers can be set for the pressure sensors of different bridges, so as to determine the bridge to which each sensor belongs. In some embodiments, the pressure information includes a position number of the pressure sensor and real-time detected pressure data. It is understood that different location numbers correspond to different locations of the bridge. And the position number of the pressure sensor is used for determining the current position of the bridge where the collision occurs according to the corresponding position number when the pressure data exceeds the standard. In addition, the system background is connected with an alarm unit, and when the pressure data reaches a set pressure threshold value, the system background outputs impact alarm information, wherein the impact alarm information comprises the corresponding pressure information. The alarm unit can prompt the current collision condition of a background manager of the system in a sound-light alarm mode. And according to actual needs, displaying collision alarm information on a display screen of a system background. Further, in some embodiments, the corresponding impact level may be determined according to different pressure data, so that the manager can intuitively and accurately know the current impact condition of the bridge.
Referring to fig. 1, in the embodiment of the present application, the pressure sensor 24 is disposed between the spring 22 and the first end of the screw 21. The pressure sensor 24 collects the pressure information transmitted by the spring 22 and uploads this pressure information to the system background. Furthermore, in some embodiments, the pressure sensor is disposed between the height-limited steel pipe 1 and the spring 22. It can be understood that the larger the pressure data acquired by the pressure sensor is, the larger the impact force to which the current bridge height-limiting and collision-preventing device is subjected is. In the embodiment of the application, the pressure sensor can select a setting position to acquire pressure information according to actual needs. The embodiments of the present application do not limit this.
More specifically, when the alarm point location of the bridge collision is carried out, the collision force is generated through the collision effect of the vehicle and the ship with the height exceeding the limit running under the bridge on the bridge, the collision force is finally transmitted to the pressure sensor through the spring 22, and the pressure information obtained by the sensor is remotely transmitted to the system background through a wired or wireless transmission mode. And displaying the data to the bridge management personnel on a terminal of a system background in real time. At the moment, the bridge manager can know the position and the size of the impact force applied to the bridge structure according to the serial number and the pressure data of the pressure sensor, so that the impact damage part, the range and the degree of the bridge structure can be estimated, impact accidents can be timely known, and a scientific coping and disposal scheme can be timely made. So as to take corresponding reasonable and scientific management measures for the bridge in time and reduce the loss and negative effects brought by the impact accidents to the maximum extent.
The height limiting steel pipe is transversely arranged on the outer side of the lower edge of the bridge, the first end of the screw is fixedly connected with the bridge, and the other end of the screw axially penetrates through the spring, radially penetrates through the height limiting steel pipe and is fixedly locked through the nut so as to fix the height limiting steel pipe. By adopting the technical means, good impact buffering effect can be realized through the height-limiting steel pipe and the spring, the setting of the anti-collision structure is simplified while the anti-collision effect of the bridge is guaranteed, the setting difficulty and the maintenance difficulty of anti-collision measures are reduced, and the setting cost and the maintenance cost of the anti-collision measures are reduced.
In addition, the pressure information of the buffer fixed structure is collected by arranging the sensor, and the pressure information is uploaded to a system background, so that real-time alarming and positioning of bridge impact are realized, and the bridge management effect is optimized.
