[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a bridge construction anti-fall device with a convenient adjustable range is designed. The anti-fall mechanism within this device blocks falling objects. The controller activates an electric push rod, which pushes the traveling wheel downwards. The downward-moving traveling wheel lands on the ground, supporting the support frame and adjustment frame. Pushing the support frame and adjustment frame, the controller moves them below the bridge deck. The controller then activates a winding motor and a servo motor. The winding motor drives the winding shaft to rotate, releasing the wound protective pad. Simultaneously, the servo motor drives a drive gear to rotate via a rotating shaft. The rotating drive gear pushes a transmission rack outwards, causing the transmission rack to move outwards. The sliding plate moves the adjusting frame to both sides of the support frame. The adjusting frame moving to both sides tightens the released protective pad. When the adjusting frame moves to the appropriate position, the controller shuts off the servo motor and the winding motor, and the adjusting frame stops moving. The electric push rod drives the traveling wheels to move upward. The rising traveling wheels enter the support frame or adjusting frame, and the support frame and adjusting frame fall to the ground. Workers use bolts to fix the support frame and adjusting frame to the ground. The tightened protective pad between the support frame and adjusting frame can block objects falling from the bridge deck. The protective area can be adjusted according to the size of the construction site, which solves the problem that the existing anti-fall device cannot change its protective area, making it inconvenient to use on site.
