Protective device for road and bridge engineering

technical field

The utility model is applicable to the field of auxiliary technology for road and bridge engineering, in particular to a protective device for road and bridge engineering.

Background technique

At present, during the construction of roads and bridges, in order not to affect pedestrian traffic, protective warning nets are often installed on bridges.

According to the patent (the publication number is "CN211368412U"), a protective device for road and bridge engineering belongs to the technical field of bridge engineering. A protection device for road and bridge engineering, comprising a fixing seat, a fixing pipe is arranged on the top of the fixing seat, a supporting column is plugged into the inside of the fixing tube, and a fixing piece is fixedly connected to the top of the supporting column; the utility model , through the cooperation between the top plate, the chute, the protective groove, the return spring, the slider, the first protective net, the second protective net and the support spring, since the return spring supports the slider, the first protective net will be There is a certain slope, if the mass is heavy, the first protective net will move downward, so that the slider moves inside the chute, and the return spring is compressed, which can make the first protective net more uniform in force and load-bearing capacity. Strong, through the support of the supporting spring and the protection of the second protective net, the protection effect can be effectively improved and the personal safety of pedestrians can be guaranteed.

However, there are still some deficiencies in the above-mentioned patents: when adjusting the slope of the protective net, the above-mentioned patent requires the operator to manually adjust the distribution of multiple groups of support columns at the bottom, and the adjustment steps are increased accordingly, thus Increasing the labor consumption of the operator will also lead to different heights and positions between different parts of the protective net. It is impossible to ensure that the protective net can block and protect falling objects horizontally, which will affect the subsequent protection quality and efficiency. Therefore, we propose a protective device for road and bridge engineering.
