Safety protective fence for road and bridge construction
The invention belongs to the technical field of protective fences, and particularly relates to a safety protective fence for road and bridge construction. The safety protective fence aims to solve the problem that the length of a protective fence in the prior art is inconvenient to change. According to the scheme, the safety protective fence comprises a lower cross rod and an upper cross rod which are provided with openings in the same direction, are parallel to each other and are of a groove-shaped structure, extending sliding rods are slidably connected to the ends of the upper cross rod and the lower cross rod, the same end rod is fixed to the same ends of the two extending sliding rods, rolling wheels are fixed to the bottom end of the end rod and the two ends of the lower surface of the lower cross rod, and protective rods which are distributed at equal intervals and are of an arch structure are fixed between the two extending sliding rods. When the safety protective fence is used and the overall length of the protective fence is not enough, the two extending sliding rods connected into the cross rods in a sliding mode can be drawn out according to the needed length, then a hook is hooked into a hanging ring at the end of the other protective fence, and therefore the length of the protective fence can be changed flexibly.
本发明属于防护栏技术领域，尤其是一种道路桥梁施工用安全防护栏，针对现有技术中的防护栏的长度不便于更改的问题，现提出以下方案，包括两根开口同向且互相平行呈槽形结构的下横杆和上横杆，且上横杆和下横杆的端部均滑动连接有延伸滑杆，两个所述延伸滑杆的同一端固定有同一个端杆，且端杆的底端以及下横杆的下表面两端处均固定有滚轮，两个延伸滑杆之间固定有等距离分布呈弓形结构的防护杆。本发明能够在使用时，当防护栏的整体长度不够的时候，可以根据需要将两个滑动连接在横杆内的延伸滑杆根据需要的长度抽出，之后再将挂钩勾再另一个防护栏的端部的挂环中即可，从而使得装置的长度变换较为灵活。
