Problems solved by technology

In the existing technology, the staff directly erect the surveying and mapping instrument on the top of the bracket, and then use the centering rod to perform centering and leveling. However, in practice, the measurement accuracy of the surveying and mapping device is also affected by the vibration of the ground near the device. These vibrations include human activities. vibrations, including microseisms inside the crust, if these vibrations can be eliminated, the accuracy of surveying and mapping will be greatly improved

Embodiment 1

[0033] combine Figure 1-Figure 5 As shown, a high-precision shockproof surveying and mapping device includes a stage 1 for placing surveying and mapping instruments, and three brackets 2 arranged under the stage 1. In order to reduce the weight of the surveying and mapping device, the main structure of the bracket 2 is a rod shape (refer to Figure 5 for specific structure details), three brackets 2 are evenly distributed along the center ring of the stage 1;

[0034] The key point of the present invention is: the main frame 3 that is used to support the stage 1 is also provided at the central position of the three supports 2, and the above-mentioned support 2 includes an outer support 21 that is arranged away from the main frame 3 and an outer support 21 that is arranged near the main frame 3. Inner bracket 22, the bottom of outer bracket 21 is provided with the pillar 5 that contacts with the ground, is used for supporting, and one end of inner bracket 22 is hinged on the to...

Embodiment 2

[0038] A high-precision anti-seismic surveying and mapping device, such as Figure 6 As shown, the device has made the following improvements on the structural basis of Embodiment 1: In order to improve the shock absorption effect of the surveying and mapping device, a shock absorbing mechanism 6 is installed on the bottom pillar 5 of the above-mentioned outer support 21, and the shock absorbing mechanism 6 includes a double-chamber column The sleeve 61 and the second spring 62, the double-chamber sleeve 61 includes a pillar chamber 63 at the top and a spring chamber 64 at the bottom, the pillar 5 is plugged into the pillar chamber 63, and the second spring 62 is vertically abutted against the spring chamber 64 The upper and lower inner walls, and the double-chamber sleeve 61 is preferably made of microporous rubber, because the double-chamber sleeve 61 of this material has a large specific surface area and deformation capacity, which can evenly transmit the vibration and impac...

Embodiment 3

[0040] A high-precision anti-seismic surveying and mapping device, combined with Figure 7-Figure 9 As shown, the device has made the following improvements on the basis of the structure of Embodiment 2: In order to further improve the shock absorption effect of the surveying and mapping device, two shock-absorbing blocks 9 are provided at the bottom of the above-mentioned main frame 3 (a symmetrical structure with a small upper part and a larger lower part) ), two shock-absorbing blocks 9 are located on both sides of the main frame 3, and are arranged symmetrically, and are hinged on the main frame 3 through a pin structure. The groove 91 and the rolling groove 91 are equipped with a rolling ball 92 that can freely roll left and right. The side edge of the rolling groove 91 has a protrusion that restricts the rolling of the rolling ball 92. During the application process, the excess vibration energy will make the shock-absorbing block 9 presents different degrees of swing, an...

Abstract

The invention discloses a high-precision anti-seismic surveying and mapping device, relating to the technical field of surveying and mapping devices, comprising a stage for placing a surveying and mapping instrument, and three brackets arranged under the stage, wherein a main frame is arranged at the center of the three brackets, the top of the main frame is connected to the bottom of the stage, the bracket comprises an outer bracket and an inner bracket, the bottom end of the outer bracket is in contact with the ground, one end of the inner bracket is hinged at the top end of the outer bracket, and the other end is hinged on the main frame; the middle portions of the outer bracket and the inner bracket are respectively provided with shock absorbers, the bottom end of the outer bracket isprovided with a pillar, and a shock absorbing mechanism is mounted on the pillar. The surveying and mapping device provided by the invention has the advantages of simple structure, convenient production and application, and stable structure. By installing a bracket on the surveying and mapping device, and installing a shock absorber, a shock absorbing mechanism and the like on the bracket, the vibration transmitted from the nearby ground is fully absorbed, reduced or even eliminated, thereby avoiding the influence on the surveying and mapping instrument placed on the top of the main frame, andimproving the accuracy of surveying and mapping.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping devices, in particular to a high-precision shockproof surveying and mapping device. Background technique [0002] Surveying and mapping instruments are instruments and devices designed and manufactured for data acquisition, processing, and output for surveying and mapping operations. They mainly include theodolites, levels, flat panels, rangefinders, and total stations. Accuracy requires centering and leveling, which is to align the center of the instrument with the station, and then keep the surveying and mapping instrument in a horizontal state. In the existing technology, the staff directly erect the surveying and mapping instrument on the top of the bracket, and then use the centering rod to perform centering and leveling. However, in practice, the measurement accuracy of the surveying and mapping device is also affected by the vibration of the ground near the device. These vibra...
