Description

Technical Field

[0001] The invention relates to the field of positioning and calibration equipment, and in particular to a positioning device for land planning boundary measurement. Background Art

[0002] In the land planning process, accurate measurement and demarcation of land boundaries is the cornerstone of subsequent work. The measurement accuracy directly determines whether land planning can be carried out reasonably and plays a key role in the efficient use of land resources. Whether it is the planning and construction of new urban areas, the renovation of old urban areas, or the implementation of large-scale infrastructure projects, accurate land boundary measurement data are important bases for planning decisions. However, there are many problems with the current land planning boundary measurement methods. Commonly used boundary markers, such as concrete boundary markers, steel nail boundary markers with aluminum caps, and lime pile boundary markers, are cumbersome to bury and require a lot of manpower and material resources. In the vast area to be planned, it is not easy to measure the boundary. However, the operation is difficult, and the boundary markers can easily lose stability due to environmental factors. Lime piles are easily damaged and offset due to rain erosion and wind erosion, affecting the accuracy of boundary measurement. Burying steel nails in hard ground requires high construction equipment and technology, and the cost is greatly increased. In addition, when encountering areas with complex terrain, existing measurement tools cannot ensure that the calibration columns are vertically inserted into the ground, resulting in deviations in boundary measurements. Traditional calibration columns are not conspicuous enough. When performing large-scale measurement operations or in poor lighting conditions, it is difficult for staff to quickly identify them, which not only reduces measurement efficiency but may also lead to planning errors. Therefore, we propose a positioning device for land planning boundary measurement. Summary of the invention

[0013] Preferably, the corner blocks are rotatably connected to the calibration column, one end of the corner blocks is arranged on the lower side of the counterweight ball, and a reflective layer is arranged on the outer side of the side frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When the present invention is performing marking work, people can first take out the calibration column from the storage bin, put the calibration column into the positioning groove, then rotate to close the positioning groove, start the air pump in the pump bin, and through the work of the air pump, the through pipe can be used to enter the air storage cavity on the upper part of the column and compress it. When the gas is compressed to a certain pressure in the air storage cavity, the pressure valve at the bottom of the air storage cavity will open to release the gas, and the high-pressure gas will impact the calibration column and push the calibration column downward, so that the calibration column will be flushed out of the bottom of the column and the bottom of the column will be deeply inserted into the soil, thereby achieving stability of the calibration column. The calibration of the land boundary point can be achieved through the calibration column, which is convenient for subsequent measurement and actual planning work.

[0015] When the column is inserted into the ground, the counterweight ball on the upper part of the calibration column will continue to move downward under the action of inertia and fall to the bottom of the column, thereby driving the column to be further inserted downward, making the calibration column more stable. When the counterweight ball moves downward, it will drive the bottom corner block to flip over. When the corner block flips over, the other end of the corner block will push the side frame outward, thereby disengaging the slots and blocks on both sides of the side frame. At this time, under the action of the coil springs on both sides of the rotating column, the side frame will unfold to a horizontal state, thereby avoiding the situation where the land is too soft and the calibration column is completely sunken into the land, which is beneficial to actual use. At the same time, the outer sides of the side frames are provided with reflective surfaces, which can effectively increase the visibility of the calibration column, facilitate large-scale calibration and positioning work, and facilitate people to plan and measure.

[0016] Before calibration, people can start the motor inside the driving bin first, and the motor can drive the gear to rotate. The gear can use the tooth groove engaged with it to drive the sliding part to slide up and down inside the driving bin, so as to adjust the distance between the bottom of the column and the ground, so as to fully cope with the undulating land outdoors. At the same time, the driving bin can be automatically adjusted under the action of gravity through the rotating rod and the fixed block, so that the column can remain vertically downward, so that the calibration column can stably maintain a vertical posture into the ground during marking, which is conducive to ensuring the accuracy of boundary point calibration and positioning.

[0017] During the process of the column automatically adjusting to maintain verticality, when the column is adjusted and the posture is stable, people can start the pump body inside the pump chamber and input gas into the universal ball seat at the end of the damping rod through the connecting pipe, so that the universal ball seat is deformed inside and the two ends of the damping rod are locked with the damping rod, thereby achieving stable support for the column and preventing it from shaking, which is beneficial to subsequent marking work.

[0018] When the column is stable, the column can be lowered by driving the motor inside the bin, and the hub motor is started at the same time. The hub motor can drive the fixed ring to rotate, and the connecting rod fixed on the outside of the fixed ring can drive the scraper to rotate quickly. The scraper can scrape the land at the bottom of the column, so that the land at the bottom of the column can be leveled, avoiding the situation where the calibration column is tilted during marking due to uneven land, which is beneficial to improving the stability of marking and positioning work. The counterweight block on one side of the fixed ring can counterweight the fixed ring, so that the overall center of gravity of the column can be kept in the center, which is beneficial to the posture adjustment work before marking.

[0023] The leveling assembly includes a hub motor 113, which is fixedly connected to the lower part of the periphery of the column 103, and a fixing ring 110 is fixedly connected to the periphery of the hub motor 113. A plurality of connecting rods 116 are fixedly connected to one side of the periphery of the fixing ring 110, and a scraper 109 is fixedly connected to the bottom of the connecting rod 116.

[0024] Wherein, the calibration component includes a pump compartment 108, a plurality of air pumps are installed inside the pump compartment 108, the output ends of the air pumps are respectively connected with connecting pipes 115 and through pipes 104, the through pipes 104 are fixedly connected to the top of the column 103 on the side away from the air pump, an air storage cavity is arranged on the inner side of the upper part of the column 103, a pressure valve is arranged in the lower part of the air storage cavity, a clamping groove 126 is arranged in the lower part of the air storage cavity, a rotating sleeve 105 is rotatably connected to the outer periphery of the clamping groove 126, the clamping groove 126 and the middle part of one side of the rotating sleeve 105 are provided with openings, a plurality of spring clamping columns 127 are installed in the lower part of the clamping groove 126, the ends of the connecting pipes 115 away from the air pump are connected with the universal ball seats at both ends of the damping rod 118, the interior of the universal ball seats are all deformable materials, and the handrail 102 is fixedly connected to the upper rear side of the frame 101; Furthermore, in the specific implementation, people can use the marking machine 1 to complete the marking work. When performing the marking work, people can first take out the calibration column 112 from the storage bin 119, and then rotate the rotating sleeve 105 so that the opening on the rotating sleeve 105 coincides with the opening on the positioning groove 126. At this time, the calibration column 112 is placed in the positioning groove 126, and the spring clamping column 127 at the lower part of the positioning groove 126 can clamp the calibration column 112 to keep the calibration column 112 in the positioning groove 126. Then, the rotating sleeve 105 is rotated to stagger the opening to achieve the closure of the positioning groove 126, and the pump is started at this time. The air pump inside the bin 108 can use the through pipe 104 to compress the gas into the air storage chamber in the upper part of the column 103. When the gas is compressed to a certain pressure inside the air storage chamber, the pressure valve at the bottom of the air storage chamber will open to release the gas. The high-pressure gas will impact the calibration column 112, pushing the calibration column 112 downward, so that the calibration column 112 will be flushed out of the bottom of the column 103, and the bottom of the plug 124 will be deeply inserted into the soil, thereby stabilizing the calibration column 112. The calibration column 112 can be used to calibrate the land boundary points, which is convenient for subsequent measurement and actual planning work.

[0025] Among them, the bottom of the calibration column 112 is fixedly connected with a plug column 124, and a counterweight ball 128 is arranged on the upper inner part of the plug column 124. The upper outer periphery of the calibration column 112 is provided with a uniformly distributed reserved groove 131, and the inner side of the reserved groove 131 is provided with a side frame 125. The top of the side frame 125 is fixedly connected with a rotating column 132. The side frame 125 is rotatably connected to the inner side of the reserved groove 131 through the rotating column 132.

The card block 130 is fixedly connected to both sides of the inner upper part of the reserved groove 131. A corner block 129 is arranged on one side of the side frame 125.

A reflective layer is arranged on the outer side of the side frame 125. Furthermore, in the specific implementation, after the column 124 is inserted into the ground, the counterweight ball 128 on the upper part of the calibration column 112 will continue to move downward under the action of inertia and fall to the bottom of the column 124, thereby driving the column 124 to be further inserted downward, making the calibration column 112 more stable. When the counterweight ball 128 moves downward, it will drive the bottom corner block 129 to flip over. When the corner block 129 flips over, the other end of the corner block 129 will push the side frame 125 outward, thereby disengaging the slots 133 on both sides of the side frame 125 from the blocks 130. At this time, under the action of the coil springs on both sides of the rotating column 132, the side frame 125 will unfold into a horizontal state, thereby avoiding the situation where the soil is too soft and causes the calibration column 112 to be completely sunken into the ground, which is beneficial to actual use. At the same time, the outer side surfaces of the side frames 125 are provided with reflective surfaces, which can effectively increase the visibility of the calibration column 112, which is beneficial to large-scale calibration and positioning work, and convenient for people to plan and measure.

[0026] Work away from: In actual use, people can use the marking machine 1 to complete the marking work. When performing the marking work, people can first take out the calibration column 112 from the storage bin 119, and then rotate the rotating sleeve 105 so that the opening on the rotating sleeve 105 coincides with the opening on the locking groove 126. At this time, the calibration column 112 is placed in the locking groove 126, and the spring clamping column 127 at the lower part of the locking groove 126 can clamp the calibration column 112 and keep the calibration column 112 in the locking groove 126. Then, the rotating sleeve 105 is rotated to stagger the opening to achieve the closure of the locking groove 126. At this time, the air pump in the pump bin 108 is started. Through the work of the air pump, the through pipe 104 can be used to compress the air into the air storage cavity at the upper part of the column 103. When the gas is in After the air storage chamber is compressed to a certain pressure, the pressure valve at the bottom of the air storage chamber will open to release the gas, and the high-pressure gas will impact the calibration column 112, pushing the calibration column 112 downward, so that the calibration column 112 will be rushed out of the bottom of the column 103, and the bottom of the plug 124 will be deeply inserted into the soil, so as to achieve the stability of the calibration column 112. The calibration of the land boundary point can be achieved through the calibration column 112, which is convenient for subsequent measurement and actual planning work. When the plug 124 is inserted into the ground, the counterweight ball 128 at the upper part of the calibration column 112 will continue to move downward under the action of inertia and fall to the bottom of the plug 124, thereby driving the plug 124 to be further inserted downward, so that the calibration column 112 can be more stable, and the counterweight ball 128 When the corner block 129 is turned downward, the bottom corner block 129 will be driven to flip. When the corner block 129 is flipped, the other end of the corner block 129 will push the side frame 125 outward, so that the slots 133 on both sides of the side frame 125 are disengaged from the blocks 130. At this time, under the action of the coil springs on both sides of the rotating column 132, the side frame 125 will be unfolded to a horizontal state, thereby avoiding the situation where the land is too soft and causes the calibration column 112 to be completely sunken into the land, which is beneficial to actual use. At the same time, the outer side surfaces of the side frames 125 are provided with reflective surfaces, thereby effectively increasing the visibility of the calibration column 112, which is beneficial to large-scale calibration and positioning work, and is convenient for people to plan and measure. Before calibration, people can first start the motor inside the drive compartment 107, and the motor can The gear is driven to rotate, and the gear can use the tooth groove 117 meshing with it to drive the sliding part 106 to slide up and down inside the driving compartment 107, so that the distance between the bottom of the column 103 and the ground can be adjusted, so that it can fully cope with the high and undulating land outdoors. At the same time, the driving compartment 107 can be automatically adjusted under the action of gravity through the rotating rod 123 and the fixed block 122, so that the column 103 can remain vertically downward, so that the calibration column 112 can stably maintain a vertical posture when marking, which is conducive to ensuring the accuracy of boundary point calibration and positioning. In the process of automatic adjustment of the column 103 to maintain verticality, when the column 103 is adjusted and the posture is stable, people can start the pump body inside the pump compartment 108.Gas is input into the universal ball seat at the end of the damping rod 118 through the connecting pipe 115, so that the universal ball seat is deformed inside, and the two ends of the damping rod 118 are locked with the damping rod 118, so that the column 103 can be stably supported and prevented from shaking, which is beneficial to the subsequent marking work. At the same time, when the column 103 is stable, the column 103 can be lowered by the motor inside the driving chamber 107, and the hub motor 113 is started at the same time. The hub motor 113 can drive the fixing ring 110 to rotate, and the fixing ring 110 The connecting rod 116 fixed on the outside can drive the scraper 109 to rotate quickly. The scraper 109 can scrape the ground at the bottom of the column 103, so that the ground at the bottom of the column 103 can be leveled to avoid the situation where the calibration column 112 is deflected during marking due to uneven ground, which is conducive to improving the stability of marking and positioning work. The counterweight block 114 on one side of the fixing ring 110 can counterweight the fixing ring 110, so that the overall center of gravity of the column 103 can be kept in the center, which is conducive to the posture adjustment work before marking.
