Abstract
The utility model relates to an energy-attenuation guide type anti-collision protection fence which solves the problem that a traditional protection fence is usually not good in impact resistance, can not play a buffering role under impact and is prone to damage. The energy-attenuation guide type anti-collision protection fence comprises main beams (3) which are fixed to a butterfly-shaped assisting plate (6). The butterfly-shaped assisting plate is composed of arched ribs (7) which are connected and fixed through soldering lugs (4). A middle beam (5) is installed in the middle of the butterfly-shaped assisting plate. A bottom beam (10) is installed at the bottom end of the butterfly-shaped assisting plate. The main beams on the butterfly-shaped assisting plate are connected and fixed through frame beams (2). The butterfly-shaped assisting plate is fixed to a bottom plate (8). The ends of the main beams, the ends of the middle beam and the ends of the bottom beam are provided with connecting rings (1). Guide devices (9) are arranged between the main beams, the middle beam and the bottom beam. The energy-attenuation guide type anti-collision protection fence is obtained.
Description
technical field:
the utility model relates to a kind of energy attenuation guidance type anticollision barrier.
background technology:
anticollision barrier is most important traffic infrastructure, and China's speedway grew up from the eighties, and it plays important influence to national economy and social development, is the important maintenance of speedway and safety guarantee facility.The just simple square and circular configuration of at present traditional anticollision barrier, the middle column that adopts connects, when there is shock accident, often vehicle body hit with guardrail together with guardrail and car body all cause injury to a certain degree, and traditional guardrail often impact resistance be not fine, while occurring to impact, do not play cushioning effect guardrail and easily damage, so just need the protective guard of impact resistance, good buffer effect to occur.
summary of the invention:
the purpose of this utility model is to provide a kind of energy attenuation guidance type anticollision barrier.
above-mentioned object realizes by following technical scheme:
a kind of energy attenuation guidance type anticollision barrier, its composition comprises: main beam, described main beam is fixed on buttferfly-type and helps on plate, described buttferfly-type helps plate to consist of arched ribs, between described arched ribs, by weld tabs, be connected and fixed, described buttferfly-type helps plate middle that middle girder is installed, described buttferfly-type helps plate bottom that bottom girder is installed, described buttferfly-type helps the main beam on plate to be connected and fixed by cruciform bracing, described buttferfly-type helps plate to be fixed on base plate, described main beam, middle girder, bottom girder end is provided with connecting ring, described main beam, middle girder, between bottom girder, be provided with guiding device.
the beneficial effects of the utility model:
1. the utility model adopts buttferfly-type to help plate, buttferfly-type helps plate to adopt arched ribs form, can improve impact resistance like this, improved the anti-impact force of protective guard, on main beam, middle girder, bottom girder, be provided with guiding device simultaneously, guiding device can rotate, thereby when there is crash, can utilize like this guiding device to guide advancing of car body to alleviate the pressure that bears of guardrail, and the while has also reduced the impact force of car body.
2. the utility model arranges buttferfly-type and helps plate arched ribs, can independently use, and after separating, can be used in one-way street, combines and can be used in two-way street, has solved the unicity that guardrail uses, and in use simple to operate, anti-impact force is strong.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
the specific embodiment:
embodiment 1:
a kind of energy attenuation guidance type anticollision barrier, its composition comprises: main beam 3, described main beam is fixed on buttferfly-type and helps on plate 6, described buttferfly-type helps plate to consist of arched ribs 7, between described arched ribs, by weld tabs 4, be connected and fixed, described buttferfly-type helps plate middle that middle girder 5 is installed, described buttferfly-type helps plate bottom that bottom girder 10 is installed, described buttferfly-type helps the main beam on plate to be connected and fixed by cruciform bracing 2, described buttferfly-type helps plate to be fixed on base plate 8, described main beam, middle girder, bottom girder end is provided with connecting ring 1, described main beam, middle girder, between bottom girder, be provided with guiding device 9.
Claims (1)
