Pulling the hook 38 moves, the hook 38 pulls the guard band 30 out of the reel 29 and snaps the hook 38 into the hanger ring 34 of the adjacent pier, so that the guard band 30 can function as a spacer.
After the protective operation is completed, the hooks 38 are removed from the links 34 of the adjacent piers, and the rotating plate 32 is rotated clockwise, whereby the reel 29 is wound up, and the protective belt 30 is retracted into the second mounting frame 27.
Since the first guide wheel 31, the second guide wheel 35, and the guide hole 37 guide the guard belt 30, the guard belt 30 is not wound when the reel 29 is retracted.
Wherein, the crashproof pier for highway construction also comprises a clamping block 39; the clamping block 39 is fixedly connected to one end of the protection belt 30 far away from the reel 29, the hook 38 is fixedly connected to the clamping block 39, and the clamping block 39 solves the problem that the hook 38 is difficult to take out due to the fact that the hook 38 is easy to clamp into the guide hole 37.
Wherein, the crashproof pier for highway construction also comprises a fixed plate 40 and a butterfly bolt 42; the fixed plate 40 is fixedly connected to the top of the anti-collision barrel 1, the fixed plate 40 is provided with a threaded hole 41, a butterfly bolt 42 is in threaded connection with the threaded hole 41, a slot 43 is formed in one side part of the discharge hole 6 away from the chute 2, and the baffle plate 5 is in insertion fit with the slot 43.
When the guard belt 30 protects, the butterfly bolt 42 is rotated clockwise, and the butterfly bolt 42 fixes the rotating plate 32, so that the guard belt 30 can be shortened or lengthened according to actual conditions, and always keeps a tight state, and the effect of isolating and protecting a construction site is achieved.
After the baffle 5 is inserted into the slot 43, the baffle 5 can be prevented from being separated from the discharge hole 6 due to the movement of the anti-collision pier, so that sand leaks from the anti-collision barrel 1.
Wherein, the material of guard plate 21 is hard rubber, and hard rubber receives the effect that self can play certain buffering after the striking, has increased the crashproof ability of crashproof mound.
It is apparent that the above examples of the present application are merely examples for clearly illustrating the present application and are not limiting of the embodiments of the present application. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. Any modifications, equivalent substitutions, improvements, etc. that fall within the spirit and principles of the present application are intended to be included within the scope of the claims of this application.
