Description

Technical Field

[0001] The invention relates to the technical field of geological surveying and mapping, in particular to a surveying and mapping instrument positioning device used for geological survey. Background Art

[0002] Engineering geological survey is a geological investigation and research work carried out to identify the geological factors that affect engineering buildings. The geological factors that need to be surveyed include geological structure or geological structure: landform, hydrogeological conditions, physical and mechanical properties of soil and rock, natural (physical) geological phenomena and natural building materials, etc. Surveying instruments are needed when conducting geological surveys.

[0003] Announcement No. CN 219734692 U discloses a geological survey surveying instrument positioning device. By setting an adjustment component and utilizing the self-locking property of the worm gear and the worm, the movable seat can move stably when the height is adjusted, and will not fall rapidly, thereby improving the protection of the device. By setting a fixing component, the device can fix different surveying instruments, making it convenient and quick to install the surveying instrument and easy to use. However, the patent still has the following problems in actual use: Although the positioning device for the surveying instrument for geological surveying is provided with an adjustment component and utilizes the self-locking property of the worm gear and the worm to enable the moving base to move stably and not fall rapidly when the height of the moving base is adjusted, the support rod cannot be stably inserted into the ground during geological surveying.

By setting the bracket fixing mechanism, not only can the first fixing cone and the reinforcement cone at the bottom of the fixed base be used to make the fixed base fit closely with the ground, thereby improving the placement stability of the entire device, but also the lifting slider is squeezed by the own weight of the device, so that the lifting slider squeezes the first connecting piece and the first spring, and under the action of the second rotating support, the unfolding rotating rod rotates around the second rotating support while driving the unfolding sliding sleeve to slide on the outside of the unfolding sliding rod, and the unfolding sliding sleeve drives the bent connecting rod and the rotating support rod to slide inside the fixed base, so that the rotating support rod and the arc-shaped supporting claw are unfolded, and the first connecting piece drives the clamping support rod to continue to move downward by stepping on the lifting slider, and when the clamping support rod squeezes the second connecting piece and the second spring, the second connecting piece pulls the stable connection The rope makes the stable connecting rope pass around the connecting pulley and pull the rotating support rod.

The top of the lifting bracket 201 is rotatably connected to a lifting turntable 202, and a lifting handle 203 is rotatably connected to the top side of the lifting turntable 202. The bottom of the lifting turntable 202 is fixedly connected to a lifting threaded rod 204, and the outer side of the lifting threaded rod 204 is threadedly connected to a lifting threaded sleeve 205.

[0022] Working principle: Before using this kind of surveying and positioning equipment for geological survey, it is necessary to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.10As shown, first, the first fixed cone 127 and the reinforcement cone 128 at the bottom of the fixed base 101 are used to make the fixed base 101 fit closely with the ground, thereby improving the placement stability of the entire device, and the lifting slider 105 is squeezed by the weight of the device itself, so that the lifting slider 105 squeezes the first connecting piece 110 and the first spring 111, and under the action of the second rotating support 113, the unfolding rotating rod 114 rotates around the second rotating support 113 while driving the unfolding sliding sleeve 115 to slide on the outside of the unfolding sliding rod 116, and the unfolding sliding sleeve 115 drives the bent connecting rod 117 and the rotating support rod 119 to slide inside the fixed base 101, so that the rotating support rod 119 and the arc-shaped supporting claw 120 are unfolded, and the lifting slider 105 is stepped on to make the first connecting piece 110 drive the pressing support rod 112 to continue When the support rod 112 moves downward, the second connecting piece 124 and the second spring 125 are squeezed, so that the second connecting piece 124 pulls the stabilizing connecting rope 121, so that the stabilizing connecting rope 121 passes around the connecting pulley 122 and pulls the rotating support rod 119. Under the action of the third rotating support 118, the rotating support rod 119 rotates downward, and the arc-shaped supporting claw 120 is inserted into the ground, so that the stable support of the fixed base 101 can be achieved. At the same time, when the lifting slider 105 descends to the top of the lifting sliding frame 102, the fixing block 108 at the top of the rotating rod 107 is engaged with the lifting slider 105, so that the lifting slider 105 is fixed, and the rotating support rod 119 and the arc-shaped supporting claw 120 can be stably inserted into the ground, further improving the support stability of the fixed base 101. Secondly, when it is necessary to move the fixed base 101, the fixed block 108 is separated from the lifting slider 105 by rotating the engaging rotating rod 107, and the rotating support rod 119 and the arc-shaped supporting claw 120 are reset under the elastic force of the first spring 111 and the second spring 125, so as to facilitate the movement of the fixed base 101. The lifting handle 203 is used to drive the lifting turntable 202 and the lifting threaded rod 204 to rotate, so that the lifting threaded sleeve 205 and the lifting limit plate 206 drive the stable connecting block 207 and the fixed support ring 208 to move up and down, and the height of the rotating disk 212 and the clamping bracket 215 can be adjusted, so as to facilitate the use of the surveying instrument. Through the gravity of the plumb bob 214 itself and under the action of the first rotating shaft 209 and the second rotating shaft 211, the rotating disk 212 and the clamping bracket 215 can be adjusted to always remain in a vertical state.

[0023] Finally, by rotating the counterweight connecting rod 213, the clamping rotating rod 217 and the bevel gear transmission assembly 218 are driven to rotate. At the same time, the bevel gear transmission assembly 218 drives the clamping threaded rod 219 to rotate, so that the clamping threaded sleeve 220 drives the clamping limit block 221 and the arc-shaped clamping plate 222 to move relative to each other, so that the surveying instrument can be clamped and fixed. The surveying instrument can be fixed for a second time by the clamping arm 224 and the fixing bolt 225, thereby improving the clamping stability of the surveying instrument. Not only does it not need to be leveled, but when vibration occurs during surveying, the counterweight connecting rod 213 and the plumb block 214 can keep the surveying instrument in a vertical state at all times, thereby improving the accuracy of surveying data.
