Special drawing-measuring device for highway design

Abstract

The invention discloses a special drawing-measuring device for highway design. The device is characterized in that a baseplate is arranged at the upper part of a box body; a folding plate is arranged on the baseplate on the box body; connection clamping rings are arranged at both ends of the box body; a left hemispheroid and a right hemispheroid are respectively arranged on the connection clamping rings; a camera shooting device and a storage battery B are arranged in the left hemispheroid; a camera shooting hole corresponding to the camera shooting device is formed in the front end of the left hemispheroid; a ranging device and a storage battery A are arranged in the right hemispheroid; and a range display connected with the ranging device is arranged at the front end of the right hemispheroid. In the fields of drawing and measuring for highway design, a plurality of new functions such as terrain shooting, terrain recording and automatic ranging are added for the device, so that the device fills in the market blank, greatly improves the working efficiency of highway survey technicians, gives the highway survey technicians great assistance in survey, measuring and draft drawing, saves a lot of manpower and material resources, and has very high actual and economic values.

Description

technical field [0001] The invention relates to a drawing measurement device, in particular to a special drawing measurement device for highway design. Background technique [0002] As is well known, highway survey and design refers to the specific completion of all the work of field survey and interior design for a highway. Due to the wide coverage and many influencing factors, it is necessary to go through a process of investigation and research ranging from large to small, and the depth of work from coarse to fine. According to the nature of use, technical level and construction scale of the highway, it is usually divided into three design methods: first stage, second stage and third stage. Among them, one-stage design is suitable for small-scale construction projects with simple technology and clear schemes, also known as one-stage construction drawing design. The construction drawing design of the first stage should adopt a fixed measurement accordingly, that is, with...

AI Technical Summary

Problems solved by technology

[0004] In the process of on-site surveying and drafting, when encountering complex terrain and landforms that need to be drawn, shooting tools are urgently needed to record the geographical features for future work and drawing needs. However, current technicians do not have professional geological photography when conducting on-site surveys equipment, which will bring great inconvenience to future work; in addition, when the technicians need to measure the distance in the survey, they often need to use external equipment such as a measuring ruler for auxiliary measurement. There is no automatic distance measuring device, which is a blank in the market. Undoubtedly, the number of tools is increased, and it is very inconvenient to measure with a ruler, especially when encountering complex terrain and needing distance measurement.

[0005] At the same time, in the process of on-site surveying and sketching, technicians carry a large number of measuring equipment and some hand-drawn drawing tools. During the survey process, a lot of manpower is required to carry and protect these measuring equipment. When walking on rough roads, you will also face problems such as difficulty in carrying tools and inconvenient walking.

During surveying, when it is necessary to design and make sketches, some drawing tools are needed. Because there are many types of drawing tools, they are not only easy to lose, but also need to be rummaged during carrying and using, which is very inconvenient. Nowadays, there is a lack of one. Measurement records, and convenient portable special equipment for staff to make sketches

[0006] In the field of highway design and painting measurement, there is no survey tool that can provide technicians with functions such as shooting records, automatic distance measurement, and drawing. new equipment, therefore, the present invention must bring huge economic value
