Problems solved by technology

Although the construction project bidding device has various functions and can automatically clean the writing board and the display screen, it needs to keep the relevant information on the writing board confidential because it is carried out by different units during the bidding process of the process cost. There are many bidding units in the entire bidding site, and each time the information on the writing board needs to be erased before the next unit can proceed to the bidding process, which delays the entire bidding process
In addition, the overall structure of the construction project bidding equipment is relatively large, which is inconvenient for subsequent storage and storage, and the entire device is inconvenient to move

Abstract

The invention discloses a bidding indication system for project cost. The system comprises a bottom U-shaped frame and a display frame, guide rail strips are fixedly arranged on the upper surfaces of the left end and the right end of the bottom U-shaped frame, a first motor is arranged at the rear end of the bottom U-shaped frame, a rotating shaft is connected to an output shaft of the first motor, and a first driving belt wheel and a second driving belt wheel are arranged on the rotating shaft front and back; a first lead screw and a second lead screw are arranged in the two sliding cavities correspondingly, and vertical strips are connected to the left end and the right end of the display frame correspondingly; a dustproof roller shutter is arranged on the front side surface of the display frame (2) above a display screen (212); the whole display frame can lie flat and stand up under the driving action of the first motor, the whole display frame can be quickly stored on the bottom U-shaped frame when the display frame is not used, and the system is small in size, convenient to store and high in practicability.

Description

technical field [0001] The invention relates to the technical field of engineering cost, and specifically discloses a bidding instruction system for engineering cost. Background technique [0002] Project cost refers to the construction price of a project, which refers to the sum of all the expected or actual costs required to complete the construction of a project. Defined from the perspective of the owner (investor), the project cost refers to the construction cost of the project, that is, all the fixed asset investment expenses that are expected to be paid or actually paid for the construction of a project. At the site of engineering cost bidding, it is often necessary to use a variety of auxiliary equipment to carry out the bidding process. [0003] The invention with the application number of CN 110060613A discloses a construction project bidding device, which includes a device base, a supporting shell fixedly connected to the left side of the top of the device base, a...
