The specific meaning of such terms in this patent will be understood by those of ordinary skill in the art as the case may be.
As shown in fig. 1, the height limiting assembly capable of alarming provided by the embodiment comprises a height limiting rod 1 horizontally arranged, two support rods 2, wherein the two support rods 2 are fixedly installed on two sides of a road respectively, and the top ends of the two support rods 2 are fixedly connected with the height limiting rod 1.
The height limiting rod 1 is perpendicular to the road direction, the height limiting rod 1 spans the road, the height limiting rod 1 mainly plays a role in interception, the set height of the height limiting rod 1 is usually the limit height of road traffic, when the height of a passing vehicle reaches or exceeds the height of the height limiting rod 1, the passing vehicle cannot smoothly pass through a subsequent road, but partial truck drivers cannot accurately judge the highest height of the vehicle, particularly a truck filled with cargoes, usually needs to be started to the front of the height limiting rod 1 to stop, and then the truck is started to observe and judge whether the height of the truck can pass through the height limiting rod 1 through naked eyes, so that a great amount of time is wasted, and the passing efficiency is reduced. In order to facilitate a driver to quickly judge whether the vehicle can pass through the height limiting rod 1, the height limiting assembly provided by the embodiment further comprises an alarm system 3.
As shown in fig. 2, the alarm system 3 includes a first transmission rod 31, a mounting plate 32, a pressure sensor 33, a baffle 34, a second transmission rod 35, a first spring 36, a second spring 37, and an alarm 38.
The height limiting rod 1 is provided with two first through holes in a penetrating mode along the road direction, the two first transmission rods 31 penetrate through the two first through holes respectively, and the first transmission rods 31 are matched with the first through holes, so that the first transmission rods 31 can slide in the first through holes in a front-back stable mode. The first transmission rod 31 is fixedly connected with the mounting plate 32 towards one end of the coming vehicle, and the bottommost end of the mounting plate 32 is not lower than the bottommost end of the height limiting rod 1. The first spring 36 is sleeved on the outer side of the first transmission rod 31, one end of the first spring 36 is fixedly connected with one end of the mounting plate 32 opposite to the coming vehicle, the other end of the first spring 36 is fixedly connected with one end of the height limiting rod 1 opposite to the coming vehicle, and the first spring 36 plays a role in elastically supporting the mounting plate 32.
The pressure sensor 33 is fixedly installed at one end of the mounting plate 32 facing the coming vehicle, the mounting plate 32 is provided with two second through holes in a penetrating manner along the road direction, the two second transmission rods 35 respectively penetrate through the two second through holes, and the second transmission rods 35 are matched with the second through holes, so that the second transmission rods 35 can stably slide in the second through holes front and back. The second transmission rod 35 towards one end of the coming vehicle and fixedly connected with the baffle 34, the baffle 34 is horizontally arranged, and the bottom end of the baffle 34 is flush with the bottom end of the height limiting rod 1. The second spring 37 is sleeved on the outer side of the second transmission rod 35, one end of the second spring 37 is fixedly connected with one end of the mounting plate 32 facing the coming vehicle, the other end of the second spring 37 is fixedly connected with one end of the baffle 34 facing away from the coming vehicle, and the second spring 37 can play a role in elastically supporting the baffle 34.
The alarm 38 is fixedly arranged on the height limiting rod 1, and the pressure sensor 33 is electrically connected with the alarm 38.
Based on the above system, when the height of the vehicle is lower than the height of the baffle 34, the vehicle can smoothly pass under the baffle 34, and the vehicle can smoothly pass through the height limiting rod 1 at this time because the bottom end of the baffle 34 is flush with the bottom end of the height limiting rod 1.
When the height of the vehicle is not lower than the height of the baffle 34, the vehicle can push the baffle 34 backwards when moving forwards to collide with the baffle 34, the second spring 37 is compressed, the second transmission rod 35 slides backwards in the second through hole, the baffle 34 moves backwards for a certain distance to collide with the pressure sensor 33, the pressure sensor 33 is stressed to transmit a signal to the alarm 38, and the alarm 38 gives an alarm after receiving the signal to remind a driver that the vehicle cannot pass smoothly. When the vehicle continues to travel forward, the first spring 36 is compressed, and the first transmission rod 31 slides backward in the first through hole, so that the pressure sensor 33 can be prevented from being damaged by rigid extrusion. When the driver knows that the vehicle cannot pass through, the vehicle should be backed up and moved away, and after the vehicle is separated from the baffle 34, the second transmission rod 35 slides forward to the original position in the second through hole under the action of the second spring 37, and the baffle 34 is separated from the pressure sensor 33. Similarly, the first transmission rod 31 slides forward to the original position in the first through hole due to the action of the first spring 36.
It should be noted that the distance between the baffle 34 and the pressure sensor 33 should be small, and when the vehicle collides with the baffle 34, the baffle 34 moves backward a small distance to collide with the pressure sensor 33. At the same time, the elastic potential energy of the first spring 36 should be greater than that of the second spring 37, avoiding that the first spring 36 has been compressed to shorten when the shutter 34 has not been in contact with the pressure sensor 33. Effectively ensures the sensitivity and rapidness of the system.
In summary, the driver can quickly judge whether the vehicle is over-high according to the method, and the driver does not need to get off the vehicle for observation. The traffic efficiency is greatly improved, and traffic jam caused by long-time stay of vehicles in front of the height limiting rod 1 can be avoided.
After the first spring 36 is compressed, if the force is suddenly released, the first spring 36 will rebound rapidly, and in order to prevent the first transmission rod 31 from sliding out of the first through hole, in this embodiment, a first stop block 39 is fixedly connected to an end of the first transmission rod 31 facing away from the vehicle. The first limiting block 39 is larger than the first through hole in size, so that the first transmission rod 31 is effectively prevented from sliding out of the first through hole.
Similarly, a second limiting block 40 is fixedly connected to one end, opposite to the vehicle, of the second transmission rod 35. The second limiting block 40 is larger than the second through hole in size, so as to effectively prevent the second transmission rod 35 from sliding out of the second through hole.
In this embodiment, as shown in fig. 2, the left and right ends of the baffle 34 are aligned with the left and right ends of the height-limiting rod 1, respectively. In this way, the bearing surface of the baffle 34 can cover the whole road, preventing the part of the vehicle exceeding the height limit from passing by the baffle 34.
The baffle 34 is fixedly provided with a buffer cushion 4 towards one end of the coming vehicle. The cushion pad 4 may be a rubber plate. The rubber sheet is soft in texture and does not have a large loss even if the vehicle collides with the cushion pad 4.
In this embodiment, the support rod 2 is vertically disposed. The supporting rods 2 are vertically arranged and have small occupied area.
The side wall of the support rod 2 can be coated with warning paint. The warning paint is beneficial to reminding drivers of timely noticing the height limiting assembly, especially under the condition of poor night vision.
