Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping equipment, and in particular to an adjustable surveying and mapping instrument positioning device for surveying and mapping. Background Art

[0002] Surveying and mapping is the process of measuring and drawing. It is based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with global navigation satellite positioning system, remote sensing, and geographic information system as its technical core. It uses measurement methods to obtain graphics and position information reflecting the current status of the ground from existing feature points and boundaries on the ground, which is used for the planning, design, and administrative management of engineering construction. In the process of using a combined surveying and mapping instrument to survey and map the corresponding project, a positioning adjustment device is needed to fix and adjust the surveying and mapping instrument.

[0003] However, as far as the currently available adjustable surveying instrument positioning devices used for surveying are concerned, commonly used surveying instruments are often supported and positioned by tripods. Due to the rugged ground at the construction site, the tripod-type supporting and positioning device cannot meet the requirements of all-terrain use. The tripod has poor adaptability to the terrain, which often causes the surveying instrument to topple over or the tripod to be unstable due to its tilt on a slope, resulting in large deviations in the surveying and mapping data, affecting the accuracy of the construction. Summary of the invention

[0004] In view of this, the present invention provides an adjustable surveying instrument positioning device for surveying and mapping, which releases the restriction of the pawl on the ratchet wheel by pulling the pawl compression reset spring B upward, and then rotates the counterweight winch counterclockwise by folding the handle to release the cable on the counterweight winch, and then releases the pawl to engage the pawl with the ratchet wheel, and ties the bottom of the cable to the stone, and then rotates the counterweight winch clockwise by folding the handle, and the counterweight winch retracts the cable until the cable is received by the stone and suspended on the ground, so that the main bracket can be guaranteed to be vertical to the ground by the gravity of the stone, ensuring the level of the surveying instrument during surveying and mapping. The invention can reduce the surveying and mapping errors, improve the surveying and mapping accuracy and the accuracy of surveying and mapping positioning, and increase the adaptability of the device to different terrains. Since stones are common materials on construction sites, there is no need to carry additional counterweights, which can reduce the weight of the device when carried and improve the convenience of carrying the device. Under the action of the reset spring A, the double limit pull rod makes the limit pin at the bottom of the double limit pull rod stuck in the limit gear of the swing base, so that the main bracket is fixed when it is adjusted to a vertical state with the ground, preventing the stone from being accidentally touched, causing the main bracket to shake, and better maintaining the stability of the main bracket, so as to improve the accuracy of surveying and mapping.

The main bracket 1 can be ensured to be vertical to the ground by the gravity of the stone, so as to ensure the horizontality of the surveying instrument during the surveying process, reduce the surveying error, improve the surveying accuracy and the accuracy of surveying positioning, and increase the adaptability of the device to different terrains. Common materials are used, so there is no need to carry additional counterweights, which can reduce the weight of the device when carried. Under the action of the reset spring A4, the double limit rod 3 makes the limit pin 301 at the bottom of the double limit rod 3 stuck in the limit gear 602 of the swing base 6, so that the main bracket 1 is fixed when it is adjusted to a vertical state with the ground to prevent stones from being accidentally touched and causing the main bracket 1 to shake, thereby better maintaining the stability of the main bracket 1. By setting a turntable 2 in the top end face of the main bracket 1, the surveying instrument can be rotated, and the main bracket 1 can perform real-time positioning operations through the locator 15, thereby preventing the device from being lost.
