On-site surveying and mapping device for building construction

Abstract

The invention discloses an on-site surveying and mapping device for building construction, and relates to the technical field of surveying and mapping devices. The on-site surveying and mapping devicecomprises a sleeve, a supporting plate, a shell and a protection mechanism, a sliding groove is formed in the upper surface of the supporting plate, an adjusting mechanism is arranged in the slidinggroove, an outer frame is fixedly connected to the upper surface of the adjusting mechanism, a binding mechanism is fixedly connected to the outer side of the outer frame, a sun-shading mechanism is arranged on the outer side of the outer frame, a protection mechanism is arranged on the outer side of the outer frame, and a rotating shaft is fixedly connected to the lower surface of the supportingplate. By arranging the protection mechanism and the outer frame, a surveying instrument can be placed in the outer frame, two cover plates in the protection mechanism can cover the front side and therear side of the outer frame, and air can be injected into an air bag through an air pipe when an air cylinder is pressed, so that the air bag can expand to protect the surveying instrument; and an air nozzle can exhaust air in the air bag when the air bag is not used, so that the air bag is shrunk and wizened, and the air bag can be conveniently inserted into the outer frame again subsequently to protect the surveying instrument.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping devices, in particular to an on-site surveying and mapping device for building construction. Background technique [0002] In the process of building construction, it is generally necessary to survey and map the place, and draw graphic measurement data to prepare for the next building construction. During the survey and mapping process, it is necessary to use surveying and mapping instruments, precision components of surveying and mapping instruments, such as imaging systems, workbenches, optical rulers, and Z The shaft transmission mechanism needs to be adjusted precisely, and all the adjusting screws and fastening screws have been fixed. The appearance of the surveying instrument has brought great convenience to the construction. [0003] A Chinese patent discloses "a BIM-based on-site surveying and mapping device for construction project cost" (patent number: CN201910786197.9), wh...

Problems solved by technology

[0004] The purpose of the present invention is in order to solve the shortcoming that exists in the prior art, as: 1, the surveying and mapping instrument in this scheme is exposed on the outside, if run into strong wind like this or be subjected to collision during use, can cause surveying and mapping instrument to fall to the ground and ground Collision may cause the surveying and mapping instrument to be damaged. 2. The surveying and mapping device in the prior art does not have a protective device for the staff. When the staff is surveying and mapping on the construction site, they are often exposed to the scorching sun. 3. The supporting legs of the surveying and mapping device in the prior art are generally exposed on the outside, and the supporting legs may be loose and swing when carried, which may cause the supporting legs to collide with other objects and suffer from bending. 4. At the same time, the existing surveying device cannot adjust its steering angle and surveying distance, so if it is necessary to fine-tune the surveying device during surveying and mapping, the entire bracket needs to be moved And adjust the position, it is easy to cause the deviation of the alignment data between and, it is very troublesome to re-calibrate the operation, and a field surveying device for construction is proposed
