[0002] Now the construction is also speeding up. The construction progress is speeding up. Under such continuous construction day and night, how to ensure the safety of pedestrians and citizens has always been the focus of the construction party, because the warning device is not bright enough, and the existing warning device cannot adjust the warning area. The effect is not good, and it can not meet the general needs, and it is very common that citizens are injured. In order to solve the above problems, we have introduced the following devices

The invention belongs to the technical field of warning devices and especially relates to a warning device for road and bridge construction. The warning device for road and bridge construction comprises a supporting table, supporting rods, a warning box and a movable bin. The supporting rods are fixedly connected to the upper surface of the supporting table, the warning box is fixedly connected tothe upper ends of the supporting rods, the number of the supporting rods is two, the supporting rods are symmetrically arranged at the lower end of the warning box, and the movable bin is formed in the warning box. According to the invention, a motor, a first threaded column, a second threaded column and a threaded cap are matched; people only need to control the motor to operate through the control switch. Therefore, a first rotating shaft is driven to rotate, the first threaded column and the second threaded column are driven to rotate under the cooperation of a first bevel gear and a second bevel gear, an expansion plate is driven to move under the cooperation of the first threaded column, the second threaded column and the threaded cap, and after the expansion plate moves to a designated position, people only need to control the motor to stop operating through the control switch.
Description
technical field [0001] The invention belongs to the technical field of warning devices, and in particular relates to a warning device for road and bridge construction. Background technique [0002] Now the construction is also speeding up. The construction progress is speeding up.
