Construction engineering management bid inviting device

Abstract

The invention discloses a construction engineering management bid inviting device which comprises a bottom board. Universal wheels are fixed to four corners of the bottom outer wall of the bottom board through screws respectively. Vertical supporting rods are welded to two ends of the top of the bottom board, a vertical electric slide rail is fixed to the outer wall of one side of one of the supporting rods, and a slider is slidably connected to the inner wall of the electric side rail. A horizontal connection rod is fixed to the outer wall of one side of the slider through a screw, a brush sleeves the outer peripheral wall of the connection rod, and a same canopy is fixed to top ends of the two supporting rods through screws. After starting of a step motor, an output shaft of the step motor drives a rotating rod to rotate together, so that a display device on a mounting board is enabled to rotate by 360 degrees to realize bidirectional display without manual adjustment; the front faceand the back face of the display screen are dedusted by the brush without manual cleaning, and accordingly workload of workers is relieved.

[0002] Building construction is an inevitable product of social and economic development. With the continuous acceleration of urbanization, the demand for building construction is also increasing, and the demand for construction engineering management is also gradually increasing, and the demand for equipment for construction engineering management It is constantly increasing. Taking bidding devices as an example, it is a necessary tool for healthy competition. Nowadays, there are many types and styles of bidding devices on the market, but there are still more or less deficiencies that affect their use. They are used for display The display screens of the bidding content are fixed and cannot be adjusted, which cannot satisfy viewers from different directions. When there is dust on the display screen, it is usually cleaned manually, and the workload of the cleaning personnel is relatively large.
