[0003] Engineering surveying instrument is a kind of measuring instrument, which is a variety of orientation, distance measurement, angle measurement, height measurement, mapping and photogrammetry instruments used in the planning and design, construction and operation management stages of engineering construction. , but the existing engineering surveying instruments have the following disadvantages when used. First, the bracket of the surveying instrument is not easy to use, occupies a large area, and is not easy to carry and transport. The measuring instrument is too large during transportation and is easy to be damaged by impact. Secondly, when the measuring instrument is in use, it is difficult to adjust the bracket at the bottom to a horizontal position when facing the ground with complex terrain, resulting in a decrease in measurement accuracy. Measurement inefficiency

Embodiment 1

[0033] Such as figure 1 and figure 2 As shown, the limiting device 402 is composed of a supporting column 401, a limiting device 402 and an adjusting device 403. A supporting column 401 is arranged between the limiting plates 5, and the supporting column 401 is connected with the limiting plate 5 through a rotating shaft. The supporting column 401 A limit device 402 is provided on one side, and an adjustment device 403 is provided at the bottom of the support column 401. The support column 401 and the adjustment device 403 are connected by the limit device 402. When the support column 401 and the adjustment device 403 need to be folded and stored, pull the limit device 402 can directly rotate and position the adjusting device 403 , which is easy to use and convenient for folding and storage of the supporting device 4 .

[0034] The limit device 402 is composed of a limit rod 40201, a limit spring 40202 and a slide plate 40203. A limit rod 40201 is provided on one side of the...

Embodiment 2

[0038] Such as figure 1 , figure 2 , image 3 , Figure 4 and Figure 5As shown, the push-off device 7 is composed of a push-off shell 701, a push-off spring 702 and a ejector rod 703. The support device 4 is provided with a push-out rod 703 on one side, and the ejector rod 703 is rotationally connected with the support device 4. The ejector rod One side of the 703 is provided with a top-opening shell 701, and a top-opening spring 702 is arranged between the top-opening shell 701 and the ejector rod 703. The ejector rod 703 and the push-off spring 702 support the ejection of the ejector rod 703, and further push away the support column 401 to facilitate the ejection of the support device 4 in the positioning device.

[0039] A baffle 6 is provided on one side of the fixed housing 40301 and the supporting device 4, and the baffle 6 is rotatably connected with the fixed housing 40301, and the supporting device 4 is blocked by the baffle 6 to limit the position of the suppor...

Embodiment 3

[0041] Such as figure 1 and Figure 6 As shown, a level 8 is provided on the top of the fixed plate 1, and the level 8 is fixedly connected to the fixed plate 1. The level 8 facilitates the adjustment of the surveying telescope 3 to a horizontal position, facilitates the operation of the surveying telescope 3, and enhances the mapping accuracy of the surveying telescope 3.

[0042] Working principle: When the positioning device needs surveying and mapping, first, carry the positioning device to the position where surveying and mapping is required, pull out the handle, the handle drives the limit rod 40201, the limit rod 40201 pulls out the support column 401, the limit spring 40202 shrinks, and the housing 40301 is fixed Rotate 180 degrees, then loosen the handle, the limit spring 40202 ejects the limit rod 40201 and inserts it into the fixed shell 40301, the fixed shell 40301 is positioned, and the four supporting devices 4 are rotated and opened respectively, and then the ba...

Abstract

The invention discloses a portable positioning device for engineering surveying and mapping. The device comprises a fixing plate, wherein a mounting plate is fixed on the top of the fixing plate; a surveying and mapping telescope is set on the top of the mounting plate; the surveying and mapping telescope is fixedly connected with the mounting plate; supporting devices are set at the bottom of thefixing plate; limiting plates are set at two sides of the supporting devices; the supporting devices are rotationally connected with the fixing plate through utilization of the limiting plates; ejection devices are set among the supporting devices; and the ejection devices are rotationally connected with the supporting devices. The device can be directly folded and stored, so occupied space is relatively small, and the positioning device is convenient for carrying and transportation. Lengths of supporting frames can be adjusted, surveying and mapping can be carried out conveniently at an outdoor floor uneven position, surveying and mapping precision is relatively accurate, and application and development of land in a later period are facilitated.

Description

technical field [0001] The invention relates to the technical field of construction engineering surveying and mapping, in particular to a portable positioning device for engineering surveying and mapping. Background technique [0002] Surveying and mapping is literally understood as surveying and drawing. It is based on computer technology, photoelectric technology, network communication technology, space science, and information science. It is based on global navigation satellite positioning system (GNSS), remote sensing (RS), and geographic information system (GIS). The technical core is to select the existing feature points and boundaries on the ground and obtain the graphics and position information reflecting the current situation of the ground through measurement means for engineering construction, planning and design and administrative management. [0003] Engineering surveying instrument is a kind of measuring instrument, which is a variety of orientation, distance m...
