[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports, and auxiliary structures. The superstructure is also called the bridge span structure, which is the main structure for crossing obstacles. When building a bridge, protective devices are usually required to protect and prevent construction workers and other personnel from standing unsteadily on the bridge and falling.

[0003] In the patent document with the published announcement number CN209162646U, a construction anti-fall device for municipal bridge engineering is provided, including a base, a screw, a waterproof motor and a fixing box, a waterproof motor is fixedly installed on the middle part of the base by screws, a connecting head is fixedly welded on the output end of the waterproof motor, a bottom plate is fixedly welded on the top of the base, and a first protective rod is respectively installed on the four corners of the bottom plate by threads; the utility model is provided with a waterproof motor to drive the screw to rotate, thereby driving the lifting plate to a set position, without the need for workers to climb up and down, and the risk of slipping can be prevented. A protective net is tied around it to avoid the risk of workers falling from the side and protect the personal safety of workers. Compared with the same type of scaffolding or elevator, it has the characteristics of small size and easy movement. During construction, only the surrounding area of ​​the device needs to be protected, which has little impact on traffic and is convenient for passage without affecting construction safety.

[0004] In actual use of the above device, the structure for height adjustment occupies the workers' construction platform, so that the workers' already smaller platform is partially occupied. For this reason, we provide a construction anti-fall device for municipal bridge engineering. Utility Model Content
