fig. 2 is a schematic diagram of the effect of the vertical turnover type automatic reset height limiting frame before and after being impacted.
Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1 to 2, the invention provides a vertical turnover type automatic reset height limiting frame, which comprises: the height-limiting horizontal connection device comprises a height-limiting horizontal connection 4, lifting hand-operated hoists 9, a front cross bar 1, a rear cross bar 2, two upright posts 7 and a top beam 16, wherein each upright post 7 is formed by assembling an upper section 71 and a lower section 72, the upper section 71 and the lower section 72 are connected through a flexible pad 19, the top beam 16 is horizontally erected between the tops of the two upper sections 71 and is fixed with the tops of the two upper sections 71 through a flange 12, the height-limiting horizontal connection 4 is horizontally arranged below the top beam 16 and is positioned between the upper sections 71, two ends of the height-limiting horizontal connection 4 are respectively suspended by the two hand-operated hoists 9 arranged on the top beam 16, the middle part of the height-limiting horizontal connection 4 is also connected with the top beam 16 through a steel wire rope 10, ribbed plates 14 are arranged on the front side and the rear side of the lower parts of the two upper sections 71, the top ends of inclined supports 8 are connected with the ribbed plates 14 on, height-limiting cross-connection 4 is connected with preceding horizontal pole 1 through hinge 13 rotation, the length of preceding horizontal pole 1 is greater than the interval of two stands 7, make preceding horizontal pole 1 flagging in upper segment 71 front side, preceding horizontal pole 1 faces upward segment 71 one side and is articulated through hinge 6 with back horizontal pole 2, the top of hinge 6 sets up spring 5, spring 5's both ends link to each other with preceding horizontal pole 1 and the relative one side of back horizontal pole 2 respectively, the length of back horizontal pole 2 is less than the interval of two stands 7, the interval of 2 downside of back horizontal pole and ground is less than the interval of 1 downside of preceding horizontal pole and ground, one side that back horizontal pole 2 deviates from preceding horizontal pole 1 is equipped with the chamfer, back horizontal pole 2 collides with the vehicle after, do not blockked by height-limiting cross-connection 4 when making back horizontal pole 2 upwards overturn around hinge 6, and extrude spring 5 when the upset, the energy of absorption. As another embodiment, when the spring 5 is disposed below the hinge shaft 6, the extension spring 5 can absorb collision energy when the rear cross bar 2 is turned upward around the hinge shaft 6 after collision with the vehicle.
The side of the front cross bar 1 opposite to the rear cross bar 2 is provided with a strip-shaped flexible material 20, and the lower side of the rear cross bar 2 facing the front cross bar 1 is also provided with a strip-shaped flexible material 20.
