Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping, in particular to an adjustable surveying and mapping stand. Background Art

[0002] Surveying and mapping is the use of measurement techniques and tools such as theodolites, total stations, GPS, etc. to determine the position, shape, and size of points on the ground, accurately measure the coordinates and height of each point on the ground, and provide basic data for urban or external topography and planning.

[0003] Among them, the application number is CN202222743478.6, which is a geographic surveying and mapping stand. The geographic surveying and mapping stand has three docking columns inserted into the docking holes at the bottom of the expansion platform, so that the support poles and the telescopic sleeve rods support the expansion platform. At the same time, the support poles and the telescopic sleeve rods are telescopic movable structures, which always support the expansion platform with the rotation and movement of the support poles, forming an extended support structure for the expansion platform, so that the surveying and mapping stand can be supported and placed more stably, so that the expansion platform can be more stably installed and used for multiple surveying and mapping instruments; among them, the shortcomings are as follows:

[0004] When the staff uses this type of geographic surveying and mapping stand to support the surveying and mapping instrument, the retractable rod on the movable ring pushes the support rod to rotate around the connecting plate, thereby unfolding the three support rods, and then the foot pad at the lower end of the telescopic rod is used to fit the ground. At the same time, the telescopic rod can be telescopic and movable inside the support rod to adjust the support height and place the surveying and mapping stand. When the surveying and mapping stand is fixed by the support rod and the foot pad is unfolded, and the height of the surveying and mapping stand is supported, because the height adjustment of the foot pad is simultaneous and cannot be adjusted separately, the surveying and mapping stand will still be prone to shaking when placed on an uneven ground, and will not be stable and will tip over, making the supporting effect of this type of geographic surveying and mapping stand relatively poor.

The staff member twists the side adjustment screw 303 of the leg B301 that is not in contact with the ground to engage and rotate the inner thread of the thread groove 304, pushing the leg B301 to slide downward under the inside of the leg A3. At the same time, the staff member observes that the pointer 305 is at the position of the scale 302, and makes the leg B301 contact the ground. Then, the staff member adjusts the other two legs B301 in the same way, while observing the tilt amplitude of the horizontal cone 403 through the wire 402. After the horizontal cone 403 is aligned with the protrusion 401, the horizontal adjustment of the surveying frame 1 is completed, which can avoid the surveying and mapping data being affected by the surveying and mapping data when the surveying and mapping instrument 108 is used for subsequent surveying and mapping, thereby improving the effect of freely performing the horizontal adjustment on the surveying and mapping frame 1.

[0030] Reference Figure 1-2 ,Furthermore, the surveying instrument 108 is electrically connected to the battery through a matching control panel.

When the staff pushes the adjustment frame 102 to rotate through the bearing and drives the surveying instrument 108 to adjust to the specified direction, the limit bracket 104 is pushed to slide into one of the relative slide-out limit grooves A101, and the limit block 107 is squeezed to drive the damping telescopic rod A106 and the outer spring to contract, and the limit bracket 104 is rotated half a circle on the inner side of the limit groove A101, so that the limit groove B105 is close to the limit block 107, and the damping telescopic rod A106 and the outer spring pop out the limit block 107 with a relatively inclined shape all around and slide into the inner side of the limit groove B105 with a relatively inclined shape all around the inner wall, so that the limit groove B105 and the limit block 107 have a larger contact area and generate greater friction, so as to stably limit the limit bracket 104. Compared with the first embodiment, the limiting effect is better.

[0033] Working principle: First, the staff will bring the surveying instrument 108 and the surveying frame 1 to the work site. When the surveying frame 1 needs to be placed on the ground, the staff will push the limit frame 203 to slide out of the limit slot C201 to drive the damping telescopic rod B204 and the outer spring to contract. After releasing the sliding stop frame 202, the sliding stop frame 202 is pushed to slide to the specified position on the inner side of the slide slot B2 in the direction away from the support leg A3 through the slider. After that, the staff will release the limit frame 203 to make the damping telescopic rod B204 and the outer spring pop out of the limit frame 203 to slide into one of the limit slots C201 to limit the sliding stop frame 202. After that, the staff will adjust the other two sliding stop frames 202 to the same position in the same way, and then push the three support legs A3 to slide out of the slide slot C404 through the rotating shaft and move them to the surrounding After unfolding and contacting the side surface of the sliding stop frame 202, the staff puts the surveying frame 1 on the ground and contacts the ground through the leg B301. Then, if the ground is rough and uneven, the support length of the leg B301 needs to be adjusted. The staff twists the side adjustment screw 303 of the leg B301 that does not contact the ground to engage and rotate in the thread groove 304, pushing the leg B301 to slide downward under the inside of the leg A3. At the same time, the staff observes that the pointer 305 is at the position of the scale 302, and after the leg B301 contacts the ground, the staff adjusts the other two legs B301 in the same way, and observes the tilting degree of the horizontal cone 403 through the wire 402. After the horizontal cone 403 is opposite to the bump 401, After the horizontal adjustment of the surveying frame 1 is completed, it can be avoided that the surveying frame 1 is not level when the surveying instrument 108 is used for surveying and mapping in the future, which affects the surveying and mapping data. Finally, the staff fixes the surveying and mapping instrument 108 on the top of the adjustment frame 102 with bolts. When the surveying and mapping instrument 108 is used for surveying and mapping at the workplace and the direction of the surveying and mapping instrument 108 needs to be adjusted, the staff rotates the limit bracket 104 and rotates it half a circle inside the limit groove A101, squeezes the limit block 107 to slide out of the limit groove B105, drives the damping telescopic rod A106 and the outer spring to contract, and releases the limit bracket 104. Push the limit bracket 104 to slide out of the limit groove A101 inside the slide groove A103. After loosening the adjustment frame 102, the staff pushes the adjustment frame 102 to rotate through the bearing, driving the surveying and mapping instrument 108 to rotate. After the plotter 108 is adjusted to the specified direction, the limit bracket 104 is pushed to slide into the inner side of one of the relative sliding limit slots A101, the limit block 107 is squeezed to drive the damping telescopic rod A106 and the outer spring to contract, and the limit bracket 104 is rotated half a circle inside the limit slot A101, so that the limit slot B105 is close to the limit block 107, and the damping telescopic rod A106 and the outer spring pop out the limit block 107 to slide into the inner side of the limit slot B105 to limit and fix the adjustment frame 102, and the surveying direction adjustment of the surveyor 108 is completed. After the surveying is completed, the staff removes the surveyor 108 from the top of the adjustment frame 102, and lifts the surveying frame 1 to push the three sliding blocks 202 to slide through the slider on the inner side of the slide slot B2 toward the direction close to the support leg A3.The extrusion limit frame 203 slides out of the limit slot C201, driving the damping telescopic rod B204 and the outer spring to contract, and pushing the leg A3 to rotate through the shaft and slide into the inner side of the slide slot C404. After that, the damping telescopic rod B204 and the outer spring pop out the limit frame 203 to slide into the inner side of the relative limit slot C201, limiting the leg A3, and completing the folding process of the surveying frame 1.
