[0012] Further, the height limiting plate is provided with a buffer layer.
[0013] The working principle and beneficial effects of the present application are as follows:
[0014] 1. The utility model mainly includes height limiting frame, monitoring mechanism, wherein, the height limiting frame mainly includes height limiting mechanism, support frame body, and the mounting rod for installing monitoring mechanism, namely, the height limiting mechanism and the monitoring mechanism in the utility model are located at different positions on the support frame, so that the driving vehicle can avoid damaging the monitoring mechanism when contacting the height limiting mechanism, or the triggering of the height limiting mechanism affects the normal operation of the monitoring mechanism.

The height limiting mechanism in the utility model mainly includes a height limiting plate, an angle sensor and a buzzer, the height limiting plate is rotatably connected to the support frame body, the detection shaft of the angle sensor is linked with the height limiting plate, and the angle sensor itself is fixed in the support frame body, and the buzzer is electrically connected with the angle sensor.

[0016] Although the height limiting plate (height limiting rod) in the utility model also needs to contact with the vehicle, the height limiting plate in the utility model can rotate due to the contact with the vehicle, so that the impact force of the vehicle acting on the height limiting plate can no longer be concentrated on a certain fixed point of the plate, but is dispersed through the entire plate surface. Rotation causes the impact force to be distributed along different areas of the plate, thereby reducing the impact pressure of a certain specific point, which can effectively reduce the risk of local damage; and in some cases, the rotation of the height limiting plate can change the motion trajectory or direction of the plate, thereby slowing down the relative speed during impact. For example, after the height limiting plate starts to rotate, the original impact path and angle will change, which can cause the contact time with the impact object to be prolonged and the instantaneous peak value of the impact force to be reduced. The impact force brought by the vehicle (only the vehicle in contact with the height limiting plate) is difficult to cause the limiting device to tilt and collapse as a whole.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. Embodiment
[0030] As Figures 1-2 shown, this embodiment proposes a height limit anti-collision device combined with monitoring facilities, which mainly includes an overhead height limit device 1 and a monitoring mechanism 2. Among them, the overhead height limit device 1 mainly includes a height limit mechanism 11, a support frame body 12, and an installation rod 13 for installing the monitoring mechanism 2. The monitoring mechanism 2 in this embodiment preferably includes multiple cameras, and the cameras are arranged in sequence along a linear direction to ensure the monitoring range of this embodiment; and the installation rod 13 is located above the height limit mechanism 11, so as to prevent some drivers with a fluke mentality from causing damage to the monitoring mechanism 2 when triggering this embodiment, and reducing economic losses.
[0031] Specifically, as Figure 1 、 Figure 8 shown, the height limit mechanism 11 in this embodiment mainly includes a height limit plate 111, an angle sensor 112, and a buzzer 113. The height limit plate 11 is rotatably connected to the support frame body 12. The detection shaft of the angle sensor 112 is linked with the height limit plate 111. The buzzer 113 is electrically connected to the angle sensor 112, and in order to ensure that the angle sensor 112 can stably play a detection role, the angle sensor 112 itself should be fixed inside the support frame body 12.
[0032] Thus, by virtue of the rotational connection between the height-limiting plate 111 and the support frame body 12, when the height-limiting plate 111 contacts a vehicle (a restricted vehicle), the height-limiting plate 111 will rotate and flip, and the impact force of the vehicle acting on the height-limiting plate 111 will no longer be concentrated on a certain fixed point of the height-limiting plate 111, but will be dispersed through the entire plate surface; rotation causes the impact force to be distributed along different regions of the height-limiting plate 111, thereby reducing the impact pressure at a certain specific point, which can effectively reduce the risk of local damage; and in some cases, the rotation of the height-limiting plate 111 can change the trajectory or direction of the height-limiting plate 111, thereby slowing down the relative speed during impact. For example, after the height-limiting plate 111 starts to rotate, the original impact path and angle will change, which can result in an increase in contact time with the impact object and a decrease in the instantaneous peak value of the impact force. Thus, the damage caused by the restricted vehicle to the present embodiment when triggering the present embodiment is effectively reduced.
[0033] And it is difficult for the impact force brought by the vehicle (only in contact with the height-limiting plate) to cause the entire height-limiting device to tilt and collapse.
[0034] At the same time, since the height-limiting plate 111 will rotate upon impact, the angle sensor 112 located inside the support frame body 12 can detect whether a restricted vehicle passes through the present embodiment by detecting whether the height-limiting plate 111 rotates: when a restricted vehicle passes through the present embodiment, it will drive the height-limiting plate 111 to rotate, thereby driving the detection shaft of the angle sensor 112 to rotate, and triggering the angle sensor 112, so that the angle sensor 112 sends an electrical signal to the control module in the buzzer 113 for controlling the buzzer 113 itself to start, causing the buzzer 113 itself to start working and emitting a sound, warning the driver and surrounding workers (security personnel, traffic police): informing the driver that the vehicle is a restricted vehicle; informing the workers that a restricted vehicle is attempting to pass through the present embodiment, so that the workers can stop the driver from continuing to drive, quickly arrive at the scene, and direct traffic at the scene.
[0035] The height-limiting plate 111 includes a trigger rotating shaft 1111 and a contact plate body 1112, the trigger rotating shaft 1111 being located between the contact plate body 1112 and the mounting rod 13, and the trigger rotating shaft 1111 being rotatably connected to the support frame body 12 by hole shaft cooperation, so as to ensure the stability of the height-limiting plate 111 on the support frame body 12.
[0036] And considering the overall width (triggering the axial length of the shaft 1111) of the height limiting plate 111 is longer, it only has two ends of the support point, the middle position is easy to sink, bend and other phenomena due to gravity, affecting the structural strength of the height limiting plate 111, the limit precision (shorten the distance between the end of the height limiting plate 111 close to the ground and the ground), therefore, the mounting rod 13 and the triggering shaft 1111 are provided with an auxiliary support structure 3, and the contact plate body 1112 is provided with an evasive opening 11121 for preventing the auxiliary support structure 3 from interfering with the overturning movement of the contact plate body 1112, avoiding the influence of the existence of the auxiliary support structure 3 on the normal rotation of the height limiting plate 111.
[0037] Specifically, as shown in Figure 3 The auxiliary support structure 3 in the embodiment includes a plurality of auxiliary support rods 31, each auxiliary support rod 31 is arranged in a linear direction in turn and is fixedly connected with the mounting rod 13, so that the auxiliary support structure 3 can more evenly disperse and share the load from the height limiting plate 111, each support rod will bear the same or similar load, avoiding some support points bearing excessive load, thereby reducing the risk of local failure or deformation. And each auxiliary support rod 31 includes a connecting rod body 311 and a cooperating ring 312, the triggering shaft 1111 is rotatably connected with each cooperating ring 312, and the evasive opening 11121 is provided with a plurality of evasive openings 11121, each evasive opening 11121 corresponds to each cooperating ring 312. That is, the middle position of the triggering shaft 1111 also has a support point in the embodiment, effectively preventing the middle position from sinking, bending and other phenomena due to gravity.
[0038] As shown in Figure 1 Each auxiliary support rod 31 and the mounting rod 13 are provided with a reinforcing rib 32, and the two sides of each auxiliary support rod 31 should have a reinforcing rib 32, so that the mounting rod 13, each auxiliary support rod 31 and each reinforcing rib 32 can form a triangular structure, and the firmness of the triangular structure ensures the support performance of each auxiliary support rod 31 to the height limiting plate 111.
[0039] At the same time, in order to further reduce the damage of the contact between the vehicle and the height limiting plate 111 to the height limiting plate 111 itself, a buffer layer 5 is arranged on the height limiting plate 111, which is preferably composed of elastic materials such as rubber, that is, the buffer layer 5 plays a buffering role by virtue of the elastic properties of the elastic materials constituting it; preferably, the buffer layer 5 is fixed on the height limiting plate 111 by adhesion, avoiding the need to damage the structure of the height limiting plate 111 itself (such as hole) for the setting of the buffer layer 5, and ensuring the structural strength of the height limiting plate 111 itself. Embodiment
[0040] On the basis of embodiment 1, as shown in Figures 4-7As shown, the mounting rod 13 in the embodiment and the contact plate body 1112 are provided with a buffer structure 4, that is, by virtue of the presence of the buffer structure 4, the impact force and the impact force applied to the embodiment when the vehicle contacts the embodiment are further reduced, thereby reducing the damage degree of the vehicle to the embodiment.
[0041] Specifically, the buffer structure 4 includes a buffer cylinder 41 and a buffer shaft 42, the buffer shaft 42 is slidingly connected in the buffer cylinder 41, and the end of the buffer shaft 42 away from the buffer cylinder 41 is rotatably connected to the contact plate body 1112, the end of the buffer cylinder 41 away from the buffer shaft 42 is rotatably connected to the mounting rod 13, and the buffer shaft 42 and the buffer cylinder 41 are provided with an elastic element 43, both ends of the elastic element 43 are fixedly connected to the buffer shaft 42 and the buffer cylinder 41. That is, when the height limiting plate 111 is impacted (contacts the vehicle), the height limiting plate 111 rotates, drives the buffer shaft 42 to move in the buffer cylinder 41, and triggers the elastic element 43 to deform, and the elastic force of the elastic element 43 plays a buffering role for the height limiting plate 111 itself.
[0042] Preferably, the mounting rod 13 and the height limiting plate 111 are respectively provided with a first rotating frame for rotatably connecting the buffer cylinder 41 and a second rotating frame for rotatably connecting the buffer shaft 42, so as to realize the linkage movement between the height limiting plate 111 and the buffer structure 4.
[0043] The elastic element 43 in the embodiment is preferably a common elastic element 43 on the market such as a compression spring, so that the elastic element 43 can be quickly replaced when it is damaged in the embodiment.
[0044] The buffer structure 4 is provided with a plurality of buffer structures 4 arranged in sequence along the linear direction and located between adjacent auxiliary support rods 31, so that the auxiliary support structure 3 and each buffer structure 4 can cooperate with each other to more evenly disperse and share the load from the height limiting plate 111 during the rotation of the height limiting plate 111. Embodiment
[0045] Based on the embodiment 2, as shown, Figure 9 The first rotating frame and the second rotating frame in the embodiment are lengthened, that is, compared with the embodiment 2, the connection positions of the buffer cylinder 41 and the first rotating frame (the rotation center of the buffer cylinder 41) and the connection positions of the buffer shaft 42 and the second rotating frame (the rotation center of the buffer shaft 42) are farther away from the height limiting plate 111, so that the height limiting plate 111 can also rotate in the opposite direction of the vehicle, avoiding that the restricted vehicle that reverses causes damage to the embodiment when passing through the embodiment. Embodiment

[0047] The above are only preferred embodiments of the present application and are not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
