A municipal engineering surveying and mapping system and its surveying and mapping method

Abstract

The invention discloses a municipal engineering surveying and mapping system and a surveying and mapping method. The system comprises a first support plate, a second support plate and a fixing ring. Connecting rods are fixedly installed on both sides of the upper end of the first support plate. A third support plate is installed horizontally and fixedly between the upper ends of the connecting rods, a fixing mechanism is arranged inside the fixing ring, a lubricating mechanism is arranged at the upper end of the third support plate, and a center position of the upper end of the second support plate is provided. There is a placement slot, a pressing mechanism is arranged at the upper end of the second support plate, and a first hole slot is opened at the center of the third support plate. When the balance ball moves in the present invention, the balls are driven to roll, so that the lubricating oil is applied to the outside of the balls, so as to ensure the rolling property. At this time, although the storage box is in a sealed state, the elastic film is squeezed by the atmospheric pressure to ensure the flow of the lubricating oil. When the ball is stationary, the ball is squeezed so that the ball seals the outlet of the connecting pipe, thereby preventing the leakage and waste of lubricating oil.

Description

technical field [0001] The invention relates to the technical field of municipal surveying and mapping equipment, in particular to a municipal engineering surveying and mapping system and a surveying and mapping method. Background technique [0002] Municipal refers to the various administrative work of the city. Also refers to market trade affairs; city management work. Including industry and commerce, transportation, public security, culture and education, environment, sanitation, capital construction, etc., some municipal projects need to be surveyed and mapped during construction to facilitate understanding of the topography. It is a high-tech measuring instrument integrating light, machine and electricity. It is a surveying and mapping instrument system integrating the functions of horizontal angle, vertical angle, distance (oblique distance, horizontal distance) and height difference. [0003] In order to ensure the accuracy of surveying and mapping, the existing tot...

Problems solved by technology

[0003] In order to ensure the accuracy of surveying and mapping, the existing total station needs to be adjusted horizontally during use. Generally, it is generally adjusted first, and then accurately adjusted through bolts to ensure that the equipment is in a horizontal state. The operation is cumbersome and reduces the measurement. Efficiency, and the support is carried out through the support frame during the measurement, but each support frame moves independently when the support is adjusted, resulting in the need to operate separately for the opening work. At the same time, due to the outdoor work during the detection work, the total station in high temperature weather does not For sunshade equipment, you need to stand for measurement work during measurement work, which will be exposed to the sun and reduce work comfort, so a device is urgently needed to solve the above problems
