Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown, the present invention includes a bottom plate 1, a tripod, and a supporting plate 2. Both the bottom plate 1 and the supporting plate 2 are circular plates. The upper end surface of the bottom plate 1 is provided with a chute 3, and the chute 3 has an arc-shaped structure. The distance D1 from the center of the bottom plate 1 is greater than the distance D2 between the tail end of the chute 3 and the center of the bottom plate 1. The groove depth of the chute 3 decreases from the head end to the end, and the chute 3 is evenly arranged along the circumferential direction. A tripod includes three telescopic rods 4, the telescopic rod 4 adopts multiple plug-in rod bodies in the prior art, and the adjacent rod bodies are positioned by bolts. The lower end of the telescopic rod 4 is hinged with the sliding rod 5, and the lower end of the sliding rod 5 is sleeved. Set the slider 6, the slider 6 is slidingly matched with the sliding groov...

Embodiment 2

[0033] The structure of this embodiment is basically the same as that of the first embodiment, the difference lies in: Figure 5 As shown, the lower end surface of the limiting protrusion 8 is provided with a return spring 10, the return spring 10 is sleeved on the lower end of the slide bar 5 and is located in the chamber 7, and the lower end of the slide bar 5 is provided with a first magnet 11, and the bottom of the blind hole 9 A second magnet 12 attracted to the first magnet 11 is arranged at the end, and the attraction force between the first magnet 11 and the second magnet 12 is greater than the elastic force of the return spring 10.

Embodiment 3

[0035] The structure of this embodiment is basically the same as that of the first embodiment, the difference lies in: Image 6 As shown, the lower end surface of the bottom plate 1 is provided with a groove 13, which can greatly reduce the weight of the entire device, and three sets of shock-absorbing sleeves 14 and walking wheels 15 are arranged on the lower end surface of the bottom plate 1, and the shock-absorbing sleeve 14 is located in the concave On the outside of the groove 13, the structure design can make the entire device slide quickly on a flat road, and the design of the shock-absorbing sleeve 14 can prevent the road bumps from damaging the measuring instrument.

Abstract

The invention discloses a height adjusting device for surveying and mapping. The device comprises a bottom plate, a tripod and a supporting plate. The bottom plate is a circular plate, the upper end face of the bottom plate is provided with sliding grooves which are each of an arc structure, the distance D1 between the head end of each sliding groove and the center of the bottom plate is larger than the distance D2 between the tail end of each sliding groove and the center of the bottom plate, the three grooves are evenly arranged in the circumferential direction, the tripod comprises three telescopic rods, the lower ends of the telescopic rods are hinged to sliding rods, the sliding rods are in sliding fit with the sliding grooves, the bottom of each sliding groove is provided with multiple blind holes, and the lower ends of the sliding rods are in inserted connection fit with the blind holes. By means of the eccentric sliding grooves, the height of a whole supporting device is accurately and finely adjusted to be kept consistent with the height of a measured target, and practical using significance is great.

Description

Technical field [0001] The invention belongs to the technical field of surveying and mapping equipment, and particularly relates to a height adjusting device for surveying and mapping. Background technique [0002] Surveying and mapping is measuring and drawing. Based on computer technology, photoelectric technology, network communication technology, space science, and information science, with global navigation satellite positioning system (GNSS), remote sensing (RS), geographic information system (GIS) as the core technology, the existing features on the ground Points and boundaries are obtained through measurement methods to reflect the current status of the ground graphics and location information for the planning, design and administrative management of project construction. [0003] In the process of measuring with theodolite or total station and other equipment, it is necessary to continuously adjust and record by the surveying personnel. In order to reduce the measurement ...
