Construction engineering cost on-site surveying and mapping device capable of achieving rapid leveling

Abstract

The invention discloses a rapid leveling construction engineering cost on-site surveying and mapping device, and the device comprises a plurality of movable bases; locking universal wheels are arranged at four opposite angles of the bottoms of the movable bases, the tops of the bases are connected with horizontal plates through adjusting mechanisms, and the tops of the horizontal plates are fixedly connected with rotating shafts. A placement plate is fixedly connected to the top of the rotating shaft, a limiting mechanism is arranged at the bottom of the placement plate, threaded rods are rotationally connected to the inner side walls of the two mounting grooves, the opposite ends of the two threaded rods penetrate through the mounting grooves and are fixedly connected with handles, and the two threaded rods are connected with a gradienter body through fixing mechanisms. According to the device, a telescopic rod and a limiting block are clamped, meanwhile, a rotating shaft rotates to drive a placement plate to rotate, meanwhile, the placement plate rotates to drive the telescopic rod to rotate, after the telescopic rod rotates to the needed position, the limiting block is inserted into an inserting groove, the placement plate is fixed, the device is located at the horizontal position, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of engineering cost surveying and mapping, in particular to a rapidly leveling on-site surveying and mapping device for construction engineering cost. Background technique [0002] Project cost refers to the construction cost that constitutes the estimated or actual expenditure of the project during the construction period. It comprehensively uses the knowledge and skills of management, economics and engineering technology to predict, plan, control, account, analyze and evaluate the project cost, etc. The work process is called project cost management. In accordance with the procedures, methods and basis stipulated in laws, regulations and standards, the prediction or determination of project cost and its components is called project valuation. The project valuation basis includes the content of valuation, Valuation methods and price standards related to engineering measurement and valuation standards, proje...

Problems solved by technology

[0003] In the prior art, when conducting on-site surveying and mapping, first set up the tripod, then take out the surveying and mapping device from the box of the surveying instrument, place it on the tripod, then perform level adjustment, and finally perform surveying and mapping, and the surveying and mapping device performs measurement on the construction site Calibration is very inconvenient, and moving the device back and forth consumes a lot of manpower. At the same time, due to the uneven ground, the position of the device is easy to tilt, and when measuring, most construction workers rely on their own feelings and experience. Calibration cannot accurately guarantee whether the surveying device is really parallel to the horizon, which will affect the measurement results, and it is not possible to measure different angles during the measurement. The entire device needs to be rotated and re-fixed. Therefore, in order to solve the above problems, a proposal A rapid leveling device for on-site surveying and mapping of construction engineering cost
