Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 and 2, a flexible energy dissipation height limiting frame is arranged in a road, a bridge, a tunnel, a pipe culvert and other areas needing protection or a traffic safety management area, and a position where the height limiting frame needs to be arranged is selected according to a field situation; this limit for height frame adopts assembled structure, adopts energy dissipation structure, can reduce the biggest impact force that collides the vehicle.

A flexible energy dissipation height limiting frame comprises a cross beam 1, wherein one side of the cross beam 1 is connected with an upright post 2 through a first connecting flange 101, and a flexible limiting piece 3 is installed on the upright post 2;

the flexible limiting part 3 comprises a bearing 301, the bottom of the bearing 301 is connected with a first limiting plate 302, one side of the first limiting plate 302 is connected with the upright post 2 through a first connecting plate 303, the top and the bottom of the bearing 301 are respectively provided with a first adapter plate 304 and a second adapter plate 305, and the first adapter plate 304 and the second adapter plate 305 are connected with the limiting rod 4 through a second connecting flange 306.

Wherein, the height of crossbeam 1, the height of stand 2 can be adjusted according to the needs on scene.

The bottom of bearing 301 is connected with dwang 501 through third flange 502, dwang 501 with the one end that bearing 301 leaves is installed and is dialled pole 503.

The rotating rod 501 is sleeved with a fixing ring 504, and the fixing ring 504 is connected with the upright 2 through a connecting rod 505.

The structures on two sides of the beam 1 are symmetrically arranged.

The limiting rods 4 on the two sides are spliced with one ends of the upright posts 2 away from each other.

Wherein, rotating the poking rod 503 can drive the rotating rod 501 to rotate, thereby driving the bearing 301 to rotate, and further driving the limiting rod 4 to rotate, and the limiting rods 4 at both sides can rotate to the position perpendicular to the upright post 2 from the horizontal position.

When the limiting rods 4 on the two sides are in a horizontal state, the limiting rods are in a contact state.

When the vehicle runs into the limiting rods 4 on the two sides, the impact force of the vehicle reaches the maximum instantly, so that the rotating rod 501 cannot rotate in time, the fixing ring 504 and the connecting rod 505 are damaged, and then only the fixing ring 504 and the connecting rod 505 need to be replaced, and the damage cost is saved to the maximum extent.

Further, since the stopper rod 4 is connected to the bearing 301, when a vehicle collides against the stopper rod 4, the impact force between the vehicle and the stopper rod 4 can be reduced.

In addition, because two gag lever posts 4 are the contact state, and not integrated into one piece or the stationary phase is connected, when the vehicle strikes two gag lever posts 4, two gag lever posts 4 easily knock off, have further reduced the impact force between vehicle and the gag lever post 4.

Each limiting rod 4 is provided with a first positioning piece and a second positioning piece which are arranged at intervals;

the first positioning element comprises a first supporting rod 401, and the first supporting rod 401 is connected with the indication board 402 through a fourth connecting flange;

the second positioning member includes a support sleeve 403, and the support sleeve 403 is sleeved with an indicator lamp 404.

Both ends of the beam 1 are arc-shaped.

That is, the both ends of crossbeam 1 are the arc, and what be connected with the arc is straight portion, promptly, crossbeam 1 integrated into one piece has guaranteed the stability of whole energy dissipation height-limiting frame.

The upright post 2 is connected with a tubular pile 103 through a tubular pile flange plate 102 at one end separated from the cross beam 1.
