[0013] Beneficial effects of the present invention:

[0014] The support bracket for bridge construction of the present invention is provided with a functional structure of a deceleration and diversion mechanism, wherein the deceleration and diversion mechanism has a certain inclination and is arranged at the outer position of the supporting steel plate, and the deceleration and diversion mechanism is composed of a receiving and guiding layer and a raised deceleration strip arranged in an array on the outer side, and the receiving and guiding layer can realize the receiving effect of fine falling objects such as dust during the construction process, thereby preventing them from falling directly downward and affecting the ecological environment and water quality problems, and the end of the deceleration and diversion mechanism is placed inside the falling object receiving body, so that the falling objects are collected and stored through the falling object cavity in the falling object receiving body, and at the same time, the raised deceleration strips arranged in an array on the surface can realize the interception and deceleration effect of the falling objects, maintenance materials or construction tools in the process of rolling downward by the raised deceleration strips when large falling objects, maintenance materials or construction tools fall, thereby preventing the problem that falling objects with a certain weight and volume have a certain destructive force when rolling down the deceleration and diversion mechanism at too fast a speed and rush out of the falling object receiving body;

[0015] The invention relates to a bridge construction support bracket for preventing falling objects from being affected by the present invention. The slow-speed diversion mechanism of the support bracket is connected by the carrying shaft of the oblique supporting steel frame and the rotatable transmission shaft in the functional angle plate. The fallen object receiving body is connected by the lifting structure in the carrying slide plate, so that the height of the fallen object receiving body can be controlled by the lifting cylinder in the carrying slide plate, thereby changing the vertical height distance between the carrying shaft and the transmission shaft, thereby changing the inclination degree of the slow-speed diversion mechanism.

At the same time, it can also be achieved that after a long period of construction, the receiving guide layer is driven to rotate clockwise around the transmission shaft and the carrying shaft, so that the falling objects remaining on the surface of the receiving guide layer and intercepted by the raised deceleration strips flow into the falling object storage body under the effect of rotation for storage.

A transmission shaft 38 is rotatably installed in the carrying angle groove 36. A deceleration guide mechanism 20 with adjustable inclination is rotatably installed between the two groups of transmission shafts 38 and the two groups of carrying shafts 18 on the same side.

[0026] During operation, the rotating shaft 18 is fixed by the welded supporting I-beam 12 and the fixed steel bar 13 between the supporting I-beam 12 and the bridge pier. At the same time, oblique supporting steel frames 15 are welded at the four corners of the supporting steel plate 11.

During the maintenance and construction process, the function of the slow-speed diversion mechanism 20 is used. Structural setting, the deceleration and diversion mechanism 20 has a certain inclination and is arranged at the outer side of the supporting steel plate 11. The deceleration and diversion mechanism 20 is composed of a receiving guide layer 40 and a raised deceleration strip 41 arranged in an outer array. The receiving guide layer 40 can achieve the receiving effect of fine fallen objects such as dust during the construction process, thereby preventing them from falling directly downward and affecting the ecological environment and water quality problems.
