Abstract

The utility model discloses a height-limited portal frame, which comprises upright columns and a cross beam disposed at upper ends of the upright columns. The height-limited portal frame is characterized in that the lower end of the cross beam is provided with anti-impact short beams and a movable hanging object, the distance from the lower end of each anti-impact short beam to the lower end of the cross beam ranges from 15mm to 20mm, and the distance from the lower end of the movable hanging object to the lower end of the cross beam ranges from 30mm to 40mm. The anti-impact cross beams are short beams which are arranged at intervals. The anti-impact short beams can stop ultra-high vehicles from passing forcedly, and when the ultra-high vehicles can produce sound when impacting to the movable hanging object so as to remind drivers of the ultra-high vehicles to drive the vehicles away from the roadway. Compared with the prior art, the height-limited portal frame emphasizes people foremost, reduces damage to vehicles, drivers and passengers to the utmost extent while protecting bridges, not only stops the ultra-high vehicles, but also guides the ultra-high vehicles to be away from the roadway by aid of height-limited marks on the portal frame.

Description

Height-limiting gantry
Technical field
The utility model relates to a kind of height-limiting gantry that bridge, tunnel etc. prevent too high vehicle pass-through that is used to stride.
Background technology
Overpass design headway is a H rice, in order to prevent destroyed by the superelevation car, avoids causing traffic accident.Need height-limiting gantry to be set in appropriate location, branch line overpass the place ahead.Present height-limiting gantry generally is made up of column and crossbeam, height by crossbeam limits current height of car, consistent with crossbeam or when being higher than crossbeam, the upper end of vehicle will bump with crossbeam when the height of car that passes through, damage vehicle and also damage portal frame simultaneously.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned the deficiencies in the prior art, and a kind of height-limiting gantry that reduces impact damage is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of height-limiting gantry, the crossbeam that comprises column and be arranged on the column upper end, it is characterized in that: be provided with crashproof short beam and movable hanger in the lower end of described crossbeam, the lower end of described crashproof short beam is 15~20mm apart from the distance of crossbeam lower end, and the distance of end distance crossbeam lower end is 30~40mm under the described movable hanger.
Described crashproof crossbeam is the short beam that is provided with at interval.
The height distance road surface of height-limiting gantry lower transverse beam is a H rice, the high H-0.2 in identity distance road surface~H-0.15 rice, H-0.4~H-0.3 rice are provided with crashproof short beam and movable suspender respectively under lower transverse beam, crashproof short beam can stop Overheight Vehicles current by force, and can find that when Overheight Vehicles are run into movable suspender sound sails out of this highway section to remind Overheight Vehicles.Compared with prior art, the height-limiting gantry of the utility model design emphasizes that people-oriented, reduces the damage to vehicle and driver and crew in the protection bridge security to greatest extent.Height-limiting gantry not only stops passing through of Overheight Vehicles, also utilizes the limit for height sign above the portal frame that Overheight Vehicles are induced this highway section simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A portion schematic diagram of Fig. 1.
Fig. 3 is the B portion schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated, as shown in Figure 1, the utility model height-limiting gantry comprises column 1, at the upper end of column 1 welding beam 2, the height distance road surface of crossbeam 2 is a H rice, and the high H-0.2 in identity distance road surface~H-0.15 rice, H-0.4~H-0.3 rice are provided with crashproof short beam 3 and movable suspender 4 respectively under crossbeam, movable suspender 4 is made of the hinge 42 of movable hanger 41 and upper end, and crashproof short beam is the short beam that is provided with at interval.In the present embodiment, crashproof short beam 3 is 15mm apart from the lower end distance H 1 of crossbeam, and movable suspender 4 is 30mm apart from the distance H 2 of crossbeam 2 lower ends, as Fig. 2, shown in Figure 3.

Claims (2)

1. height-limiting gantry, the crossbeam that comprises column and be arranged on the column upper end, it is characterized in that: be provided with crashproof short beam and movable hanger in the lower end of described crossbeam, the lower end of described crashproof short beam is 15~20mm apart from the distance of crossbeam lower end, and the distance of end distance crossbeam lower end is 30~40mm under the described movable hanger.
2. height-limiting gantry according to claim 1 is characterized in that: the short beam of described crashproof crossbeam for being provided with at interval.
