Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, a specific embodiment of the utility model is a highway is safety device for side slope with prevent falling rocks protection, including supporting seat 1, this supporting seat 1 vertical setting, the screw fastening is passed through to the bottom, the back is fixed through bracing piece 2. Be equipped with two at least toper crushing boards 3 and ejector pad 4 on the supporting seat 1, 3 tail end both sides of toper crushing board are connected to ejector pad 4 through connecting rod 7, ejector pad 4 is connected with and blocks the subassembly, and when toper crushing board 3 pressurized, connecting rod 7 rotates and makes ejector pad 4 outwards release and block the subassembly. During the use, when the mountain upper portion falling rocks pound on the surface of toper crushing board 3, the pointed end of toper crushing board 3 can carry out the breakage to great falling rocks, and toper crushing board 3 pressurized and drive articulated connecting rod 7 and deflect this moment makes connecting rod 7 support and presses ejector pad 4 and remove, and ejector pad 4 drives and blocks the subassembly and further smash falling rocks to effectively block the protection to great falling rocks.
Specifically, it includes crushing pole 11, baffle 12, briquetting 10 and compression spring 14 to block the subassembly, briquetting 10 is fixed on ejector pad 4, briquetting 10 is trapezoidal briquetting 10, trapezoidal briquetting 10 both ends are connected to the inclined plane of two ejector pads 4, are formed with movable groove 9 between two ejector pads 4, and ejector pad 4 inclined plane and the cooperation of trapezoidal briquetting 10 inclined plane slide, make trapezoidal briquetting 10 remove to baffle 12 one side, and the crushing pole stretches out from the inside through-hole of baffle this moment and further smashes the rockfall.
