Abstract

The invention belongs to the field of equipment for construction costs, and particularly discloses a lifting type working table for the construction costs. The lifting type working table for the construction costs comprises a table top, wherein a vertical display board is arranged on the table top, and the display board is connected with a wiping mechanism. The wiping mechanism comprises a transverse sliding rail vertically and slidably connected to the table top, a sliding seat is transversely and slidably connected to the sliding rail, and a sliding driving piece for driving the sliding seatto slide on the sliding rail is connected to the sliding seat; a driving shaft is rotationally connected with the sliding seat, and a rotating rod is fixed to the driving shaft, and wiping brushes are separately connected to both ends of the rotating rod; and a pressing piece for driving the wiping brushes to move close to the display board is further arranged below the sliding seat, and a scraping board capable of scraping the wiping surfaces of the wiping brushes is fixed above the sliding seat. According to the lifting type working table for the construction costs, the problem that the wiping effect of a blackboard eraser to be poor due to the fact that chalk dust forms blocks on a sponge of the blackboard eraser when a display board on an existing working table for the construction costs is manually wiped.

Description

technical field [0001] The invention relates to the field of equipment for engineering cost, in particular to a lift-type workbench for engineering cost. Background technique [0002] Project cost refers to the total cost of carrying out a certain project construction. Project cost is a broad concept, and it has different meanings on different occasions. Due to different research objects, project cost includes construction project cost, single project cost, unit project cost and construction installation project cost. Project cost is the basis for project decision-making, an important basis for project financial analysis and economic evaluation, the basis for formulating investment plans and controlling investment, and an indicator for evaluating investment effects. [0003] When working, cost engineers often use lift-type engineering cost special workbenches to meet the work needs of workers of different heights. Usually, there is a vertical display board installed on the...
