Description

Technical Field

[0001] The present 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 are the cornerstones 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 an important basis 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 large areas to be planned, accurate land boundary measurement data are not available. However, the operation is difficult, and 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 workers 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

[0011] Preferably, the leveling assembly includes a hub motor, which is fixedly connected to the lower part of the periphery of the column. A fixing ring is fixedly connected to the periphery of the hub motor, and a plurality of connecting rods are fixedly connected to one side of the periphery of the fixing ring. The bottom of the connecting rods is fixedly connected to a scraper.

[0012] Preferably, the calibration component includes a pump compartment, and multiple air pumps are installed inside the pump compartment. The output ends of the air pumps are respectively connected to connecting pipes and through pipes. The sides of the through pipes away from the air pumps are fixedly connected to the top of the column. An air storage cavity is provided on the inner side of the upper part of the column, a pressure valve is installed in the lower part of the air storage cavity, and a positioning groove is provided at the lower part of the air storage cavity. A rotating sleeve is rotatably connected to the outer periphery of the positioning groove.

[0013] Preferably, the bottom of the calibration column is fixedly connected to an insertion column, the upper inner part of the insertion column is provided with a counterweight ball, the upper outer periphery of the calibration column is provided with evenly distributed reserved grooves, the inner sides of the reserved grooves are provided with side frames, the tops of the side frames are fixedly connected to rotating columns, the upper parts of both sides of the side frames are provided with card slots, the inner sides of the card slots are engaged with card blocks, the card blocks are fixedly connected to both sides of the upper inner part of the reserved grooves, and one side of the side frame is provided with a corner block.

[0015] Preferably, the locking groove and the middle part of one side of the rotating sleeve are both provided with openings, and a plurality of spring locking columns are installed in the lower part of the locking groove.

[0016] Preferably, the ends of the connecting tubes away from the air pump are connected to the universal ball seats at both ends of the damping rod, and the interiors of the universal ball seats are made of deformable materials.

[0017] Preferably, the side frames are rotatably connected to the inner side of the reserved groove through a rotating column, and coil springs are provided on both sides of the outer periphery of the rotating column.

[0018] 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 provided on the outer side of the side frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 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 slot, and then rotate to close the positioning slot, start the air pump inside the pump bin, and through the work of the air pump, the gas can be compressed by using the through pipe to the air storage chamber on the upper part of the column. When the gas is compressed to a certain pressure in the air storage chamber, 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 and push the calibration column downward, so that the calibration column will be rushed 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 column can be used to calibrate the land boundary points, which is convenient for subsequent measurement and actual planning work.

[0021] 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 soil is too soft and the calibration column is completely sunken into the ground, 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.

[0022] Before calibration, people can first start the motor inside the drive bin, which can drive the gear to rotate through the motor, and the gear can use the tooth groove engaged with it to drive the sliding part to slide up and down inside the drive bin, so as to adjust the distance between the bottom of the column and the ground, so as to fully cope with the high and low height of the outdoor land. 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 maintain a stable vertical posture into the ground during marking, which is conducive to ensuring the accuracy of boundary point calibration and positioning.

[0023] 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 conducive to subsequent marking work.

[0024] When the column is stable, the motor inside the drive bin can be used to lower the column, and the hub motor can be 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, thereby leveling the land at the bottom of the column to avoid the deviation of the calibration column during marking due to uneven land, which is conducive to improving the stability of the marking and positioning work. The counterweight block on one side of the fixed ring can be used to counterweight the fixed ring, so that the overall center of gravity of the column can be kept in the center, which is conducive to the posture adjustment work before marking.

[0034] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0035] like Figures 1-8 The device for measuring land planning boundaries is shown, comprising a marking machine 1, which includes a posture adjustment component, a leveling component, a calibration component, a calibration column 112, and a main structure. The main structure includes a frame 101, a storage bin 119 fixedly connected to the inner rear portion of the frame 101, a plurality of calibration columns 112 disposed within the storage bin 119, and pump bins 108 mounted on both rear sides of the frame 101.

[0036] The posture adjustment component is used to adjust the calibration posture before positioning;

[0037] The leveling component is used to level the land before calibration;

[0038] The calibration component is used to stimulate the calibration column 112 to calibrate and locate the land boundary points;

[0039] The main structure is used to carry the posture adjustment component, the leveling component, the calibration component and the calibration column 112;

[0040] The posture adjustment component includes a column 103, a sliding portion 106 is provided in the middle of the column 103, a plurality of tooth grooves 117 are provided in the middle of the outer periphery of the sliding portion 106, a driving chamber 107 is slidably connected to the middle of the outer periphery of the sliding portion 106, a plurality of motors are installed inside the driving chamber 107, the motor driving ends are fixedly connected to gears, the gears are meshed with the tooth grooves 117, both sides of the outer periphery of the driving chamber 107 are rotatably connected to the rotating rod 123, the end of the rotating rod 123 away from the driving chamber 107 is rotatably connected to the fixed block 122, and the fixed block 122 is away from the rotating rod 123. A slider 121 is fixedly connected to the middle of one end, a slide 120 is provided on the side of the fixed block 122 away from the drive bin 107, a fixed column 111 is fixedly connected to the middle of the side of the slide 120 away from the fixed block 122, the end of the fixed column 111 away from the slide 120 is fixedly connected to the main structure, and the slider 121 is slidably connected to the inner side of the slide 120. A damping rod 118 is movably connected to the middle of the rear side of the outer periphery of the drive bin 107 through a universal ball joint, and the end of the damping rod 118 away from the drive bin 107 is movably connected to the storage bin 119 through a universal ball joint;

[0041] Furthermore, in a specific implementation, before calibration, people can first start the motor inside the drive chamber 107, which can drive the gear to rotate. The gear can use the tooth groove 117 engaged with it to drive the sliding part 106 to slide up and down inside the drive chamber 107, thereby adjusting the distance between the bottom of the column 103 and the ground, so as to fully cope with the high and low land outdoors. At the same time, the driving chamber 107 can be automatically adjusted under the action of gravity through the rotating rod 123 and the fixing block 122, so that the column 103 can remain vertically downward. The calibration column 112 can be kept stably vertically into the ground during marking, which is beneficial to ensuring the accuracy of boundary point calibration and positioning. During 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 chamber 108 and input gas 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, thereby achieving stable support for the column 103 and preventing it from shaking, which is beneficial to subsequent marking work.

[0042] The leveling assembly includes a hub motor 113, which is fixedly connected to the lower part of the outer periphery of the column 103. A fixing ring 110 is fixedly connected to the outer periphery of the hub motor 113. A plurality of connecting rods 116 are fixedly connected to one side of the outer periphery of the fixing ring 110. The bottom of the connecting rods 116 are fixedly connected to scrapers 109. The scrapers 109 on both sides are set in an inclined state. A counterweight 114 is fixedly connected to the middle part of the outer periphery of the fixing ring 110 away from the connecting rods 116.

[0043] Furthermore, in specific implementation, after the column 103 is stabilized, the column 103 can be lowered by driving the motor inside the bin 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 connecting rod 116 fixed on the outside of the fixing ring 110 can drive the scraper 109 to rotate rapidly. The scraper 109 can scrape the land at the bottom of the column 103, thereby leveling the land at the bottom of the column 103, avoiding the situation where the calibration column 112 is tilted during marking due to uneven land, which is conducive to improving the stable development 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.

[0044] Among them, the calibration component includes a pump compartment 108, and multiple air pumps are installed inside the pump compartment 108. The output ends of the air pumps are respectively connected to 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 chamber is provided on the inner side of the upper part of the column 103, and a pressure valve is installed in the lower part of the air storage chamber. A positioning groove 126 is provided at the lower part of the air storage chamber. The outer periphery of the positioning groove 126 is rotatably connected to a rotating sleeve 105. The positioning groove 126 and the middle part of one side of the rotating sleeve 105 are both provided with openings. A plurality of spring clamping columns 127 are installed in the lower part of the positioning groove 126. The ends of the connecting pipes 115 away from the air pump are connected to the universal ball seats at both ends of the damping rod 118. The interior of the universal ball seats is made of deformable material. The upper rear side of the frame 101 is fixedly connected to the armrest 102.

[0045] Furthermore, in the specific implementation, people can complete the marking work of the marking machine 1. When performing the marking work, people can first take out the calibration column 112 from the storage bin 119, and then rotate the rotary sleeve 105 so that the opening on the rotary 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. The spring clamping column 127 at the lower part of the positioning groove 126 can clamp the calibration column 112 and keep the calibration column 112 in the positioning groove 126. Then, the rotary sleeve 105 is rotated to stagger the opening to achieve the closure of the positioning groove 126. At this time, the pump is started. The air pump inside the bin 108 can use the through pipe 104 to compress the gas into the air storage chamber on 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.

[0046] Among them, the bottom of the calibration column 112 is fixedly connected with a plug column 124, and a counterweight ball 128 is provided 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 frames 125 are rotatably connected to the inner side of the reserved groove 131 through the rotating column 132. Coil springs are provided on both sides of the outer periphery of the rotating column 132. A clamping groove 133 is provided on the upper part of both sides of the side frame 125. A clamping block 130 is clamped on the inner side of the clamping groove 133. The clamping block 130 is fixedly connected to both sides of the inner upper part of the reserved groove 131. A corner block 129 is provided on one side of the side frame 125. The corner block 129 is rotatably connected to the calibration column 112. One end of the corner block 129 is set on the lower side of the counterweight ball 128, and a reflective layer is provided on the outer side of the side frame 125.

[0047] Furthermore, in specific implementation, when 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 inserted further 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 block 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 to a horizontal state, thereby avoiding the situation where the soil at this location 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.

[0048] Work away from:

[0049] In actual use, people can complete the marking work of the marking machine 1. When performing the marking work, people can first take out the calibration column 112 from the storage bin 119, and then rotate the rotary sleeve 105 so that the opening on the rotary 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 and keep the calibration column 112 in the positioning groove 126. Then, the rotary sleeve 105 is rotated to stagger the opening to achieve the closure of the positioning groove 126. At this time, the air pump inside the pump bin 108 is started, and the air pump can use the through pipe 104 to compress the air into the air storage chamber 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. 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, thereby achieving stability of 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. When the plug 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 plug 124, thereby driving the plug 124 to be further inserted downward, making the calibration column 112 more stable, and the counterweight ball 128 When the cam 125 is turned downward, the bottom corner block 129 will be driven to flip. When the corner block 129 flips, 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 preventing the calibration column 112 from being completely sunken into the ground due to the soft 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 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 engaged with it to drive the sliding part 106 to slide up and down inside the driving chamber 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 low height of the outdoor land. At the same time, the driving chamber 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 be kept vertically downward, so that the calibration column 112 can be kept vertically into the ground during 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 chamber 108.The gas is inputted 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 and the two ends of the damping rod 118 are locked with the damping rod 118, thereby achieving stable support for the column 103 and preventing it from shaking, which is beneficial for subsequent marking work. At the same time, when the column 103 is stable, the motor inside the drive chamber 107 can be used to lower the column 103, 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 can be used to rotate. The externally fixed connecting rod 116 can drive the scraper 109 to rotate rapidly. The scraper 109 can scrape the ground at the bottom of the column 103, thereby leveling the ground at the bottom of the column 103. This prevents the calibration column 112 from tilting 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 maintained in the center, which is conducive to posture adjustment before marking.
