[0002] The main problem of traditional support devices used in highway bridge construction during use is that they do not have the ability to adjust the height of construction equipment and tools, so that the movement of construction equipment or tools often requires cranes or manual handling, which is laborious and time-consuming, and leads to increased costs. Secondly, the traditional support devices used in highway bridge construction also have the problem of not being able to clamp and restrict construction equipment or tools during use, resulting in the construction equipment or tools being unstable during the lifting process, and easily shaking or falling, posing certain safety hazards. Utility Model Content

[0009] As a preferred technical solution of the present invention: a control panel is fixedly installed on the outer side of the frame, and the motor is electrically connected to the control panel.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The bracket used for highway bridge construction uses a screw rod and a threaded block in combination, uses a control panel to control the motor to work, drives the threaded block to rise on the outer edge of the screw rod through the power output shaft of the motor, and the square plate is raised together by the fixed assembly of the square plate and the outer edge of the threaded block. The threaded rise of the square plate can be limited by the arrangement of two sliding blocks and the cooperation of the matching round rods, and the rise of the square plate can drive the lifting rod to rise on the inner wall of the fixed ring.

[0012] 2. The bracket used for highway bridge construction uses a clamp and a spring in combination, and utilizes a bolt to connect with the threaded connection of the upper end of the cylinder. When the bolt is turned clockwise, the bolt descends at the upper end of the cylinder, thereby driving the clamp to squeeze the spring to deform and shrink, thereby reducing the gap between the clamp and the placement table, clamping and restricting the construction equipment or tools, and avoiding the safety hazard of shaking or falling of the construction equipment or tools during the lifting process.
