Abstract

The utility model discloses a vehicle limit for height frame. The anti-blocking device comprises a support frame, swing arms and blocking rods, wherein the support frame is of an inverted U-shaped structure, a cross rod is arranged at the bottom of the support frame, the two support rods of the support frame are respectively rotated to be connected with the swing arms, the far ends of the two swing arms are respectively provided with a fixed hoop, the blocking rods are suspended in the middle of the support frame through a plurality of connecting ropes, and the swing arms are connected with the fixed hoops at the two ends of the blocking rods. The far end of the swing arm is fixedly connected with the support frame through a connecting rope. The supporting frame, the swing arm and the blocking rod are of hollow structures. The utility model discloses a pair of vehicle limit for height frame can block the vehicle when the vehicle speed passes limit for height frame at the excessive speed, and the damage of furthest reduction vehicle simultaneously protects vehicle and people's safety, has fine social value.

Description

Vehicle height limiting frame

Technical Field

The utility model relates to a traffic field, in particular to vehicle limit for height frame.

Background

The height-limiting structure is generally applied to the positions of bridges, tunnels and the like which have limitation on the passing height of vehicles. The function of the device is to block the passing of the ultrahigh vehicle, thereby avoiding the damage to bridges, tunnels and the like. The common structure of the height limiting frame is generally in a door shape and comprises two upright posts and a height limiting cross beam at the top, and when an ultrahigh vehicle forcibly passes through the height limiting frame, the ultrahigh vehicle can collide with the height limiting cross beam at the top, so that the passage of the ultrahigh vehicle is limited.

At present, when a common height limiting frame structure is impacted by an ultrahigh vehicle, because the existing height limiting rod and the height limiting frame are in rigid connection structures, the height limiting beam and the ultrahigh vehicle have huge mutual impact in a short time, no buffer exists during vehicle impact, the vehicle is damaged, and particularly when the impact speed is high, passengers in the vehicle are likely to be injured

Disclosure of Invention

For solving the defect of the traditional limit for height frame that mentions in the background art, the utility model discloses a novel vehicle limit for height frame has been demonstrated.

In order to achieve the above purpose, the following technical solutions are provided:

the utility model provides a vehicle limit for height frame, includes support frame, swing arm, arresting bar, the support frame is the type of falling U structure, the support frame bottom sets up the horizontal pole, two support bars of support frame rotate respectively and connect the swing arm, two swing arm distal ends set up fixed hoop respectively, arresting bar use a plurality of connecting ropes hang in the middle part of support frame, arresting bar's both ends by fixed hoop connects the swing arm.

Furthermore, the far end of the swing arm is fixedly connected with the support frame through a connecting rope.

Furthermore, the support frame, the swing arm and the blocking rod are of hollow structures.

The utility model has the advantages that:

1. the utility model discloses a pair of vehicle limit for height frame can block the vehicle when the vehicle speed passes limit for height frame at the excessive speed, and the damage of furthest reduction vehicle simultaneously protects vehicle and people's safety.

2. The utility model discloses a vehicle limit for height frame, when the vehicle striking blocks the bar, fixed hoop is destroyed, and the swing arm swing has effectively cushioned the striking of vehicle, blocks the bar simultaneously and is connected through being connected the rope with the support frame, has avoided falling of blocking the bar to injure by a crashing object of vehicle and people.

fig. 2 is a schematic diagram of a three-dimensional structure of a height-limiting frame of a vehicle after being impacted.

Detailed Description

In order to make the technical solutions of the present invention clearer and clearer for those skilled in the art, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings, but the embodiments of the present invention are not limited thereto.

As shown in fig. 1-2, a vehicle limit for height frame, includes support frame 1, swing arm 2, hinders rail 3, support frame 1 is the type of falling U structure, two bracing piece bottoms of support frame 1 set up horizontal pole 11, two bracing pieces of support frame 1 rotate respectively and connect

swing arm

2, 2 distal ends in two swing arms set up fixed hoop 21 respectively, hinder rail 3 use a plurality of connecting ropes hang in the middle part of support frame 1, hinder the both ends of rail 3 by fixed hoop 21 connects. The far end of the swing arm 2 is fixedly connected with the support frame 1 through a connecting rope 12. The supporting frame 1, the swing arm 2 and the blocking rod 3 are of hollow structures. The two ends of the arresting bar 3 are in clearance connection with the fixed hoops 21 on the swing arms.

When the vehicle passes through the vehicle limit for height frame at a high speed, the vehicle strikes and blocks the barrier rod 3, the fixed hoop 21 is destroyed by the impact force, the swing arm 2 swings to one side, the fixed hoop 21 is deformed to the plastic by elastic deformation, the impact force is effectively buffered, the damage of the impact force to the vehicle is reduced, and the injury of personnel is reduced.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and those skilled in the art can make many variations and modifications of the present invention without departing from the scope of the present invention by using the method and contents disclosed above.

Claims
