Protective fence for road and bridge construction
The invention discloses a protective fence for road and bridge construction, and relates to protective fences used during road and bridge construction. The protective fence is mainly designed for solving the problems that an existing protective fence is tedious in weight increasing installation and the like. The device comprises two supporting frames, a supporting plate is connected between the bottoms of the two supporting frames, the bottom of a weight increasing bag is fixed to the supporting plate, an opening is formed in the top of the weight increasing bag, and a liquid outlet is formed in the bottom of the weight increasing bag; and an extrusion roller is arranged below the opening of the weight increasing bag. The supporting frame is provided with a vertical sliding rail, the sliding frame is arranged on the vertical sliding rail, a sliding block is arranged on a horizontal sliding rail of the sliding frame, the spring is fixed to the sliding frame and the sliding block, the extrusion roller is fixed to the sliding block on the sliding frame, a lead screw is arranged on one supporting frame, a nut is fixed to the sliding frame, a rotating wheel is fixed to the upper end of the lead screw, and a guardrail assembly is arranged above the weight increasing bag. A plurality of cross rods are connected between the two shear-fork type telescopic mechanisms of the guardrail assembly, the lower ends of the shear-fork type telescopic mechanisms are connected with the sliding frame, and the upper ends of the shear-fork type telescopic mechanisms are fixed to the top of the supporting frame. The method has the advantage of easy weight increment.
一种道路桥梁施工用防护栏涉及道路桥梁施工时使用的防护栏。主要是为解决现有的防护栏增重安装繁琐等问题而设计的。它包括两个支撑架，两个支撑架的底部之间连接有支撑板，增重袋底部固定在支撑板上，增重袋顶部有开口、底部有排液口；增重袋开口下方设有挤压辊。支撑架有竖直滑轨，滑动架设置在竖直滑轨上，滑动架的水平滑轨上有滑块，弹簧与滑动架和滑块固定，挤压辊与滑动架上的滑块固定，一个支撑架上设置有丝杆，滑动架上固定有螺母，丝杆的上端固定有转轮，增重袋上方有护栏组件，护栏组件的两个剪叉式伸缩机构之间连接有若干个横杆，剪叉式伸缩机构的下端与滑动架连接，上端固定在支撑架的顶部。优点是增重容易。
