Specific embodiment
With reference to Figure of description and specific embodiment, the utility model will be further described：
Embodiment 1
As shown in Figures 1 and 2, fixed to hit not bad height-limiting frame, the height-limiting frame includes support body, and support body top is crossed with
Buffering limit for height crossbeam 3, described buffering limit for height crossbeam 3 is rotated with support body and is connected, when there is external force collision to buffer limit for height crossbeam 3,
Buffering limit for height crossbeam 3 is rotatable.Described support body includes two columns 1, and described column 1 is triangle frame structure.It is described
The top of column 1 be crossed with fixed beam 6, the bottom of fixed beam 6 is hinged with buffering limit for height crossbeam 3.Described buffering limit for height crossbeam 3
The telescopic spring pin 8 with the corresponding matching of jack 7 is provided with the left and right sides.The material of described buffering limit for height crossbeam 3 is reinforcing bar
Concrete, the outer surface of described buffering limit for height crossbeam 3 is enclosed with metal (stainless steel or special steel) material of resistance to collision.It is described
Buffering limit for height crossbeam below be provided with electric rotating mechanism.
