Description

Technical Field

[0001] The invention relates to the technical field of vertical correction devices, in particular to a vertical correction device for remote sensing and mapping landmarks. Background Art

[0002] In remote sensing mapping, it is often necessary to set up landmarks. During the mapping process, the landmarks are set in advance and the location and height of the landmarks are obtained. In remote sensing mapping, the landmarks are measured by surveying equipment, and then the measured data can be compared with the known landmark data to correct the errors of the surveying equipment. When correcting parameters such as height, since the length of the landmark pole is fixed, in order to accurately know the height of the sensor on the landmark pole, the landmark pole needs to be kept perpendicular to the horizontal plane. Therefore, when setting the landmark pole, the landmark pole needs to be vertically corrected to avoid the landmark pole being skewed when it is installed. During the installation process of existing remote sensing mapping landmark poles, the pole is mostly vertically calibrated by a level bubble. The legs of the pole need to be constantly adjusted to correct the verticality of the pole. The accuracy of the level bubble is not high, and it needs to be adjusted repeatedly, which is inconvenient to use. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5In an embodiment of the present invention, a vertical correction device for remote sensing mapping includes a support frame 100, a horizontal support mechanism 200, and a locking mechanism 300. The support frame 100 is used to be placed on the ground. The support frame 100 includes a base 110. One side of the top surface of the base 110 is fixedly connected to two vertical frame groups 120, and the other side of the top surface of the base 110 is fixedly connected to two vertical frame groups 130. The horizontal support mechanism 200 is arranged on the vertical frame group 120 and the vertical frame group 2 130. The horizontal support mechanism 200 includes two containing members 220, and one of the containing members 220 can be moved to the top of the other containing member 220. Liquid is contained in the two containing members 220. The locking mechanism 300 is used to clamp and fix with the benchmark. The locking mechanism 300 includes two hollow members 310. The two hollow members 310 correspond to the two containing members 220 one by one. The hollow members 310 are used to float on the liquid in the corresponding containing members 220.

[0030] Specifically, the support frame 100 is placed at the marking point so that the containing member 220 is roughly aligned with the top of the marking point, the locking mechanism 300 is clamped and fixed with the benchmark, and the locking mechanism 300 is moved to the horizontal support mechanism 200 so that the hollow member 310 floats on the containing member 220. By setting the liquid level in the containing member 220, when the support frame 100 is in an inclined state, the liquid level in the containing member 220 is also in a horizontal state. After the two hollow members 310 float on the containing member 220, after the locking mechanism 300 clamps the benchmark, the overall center of gravity of the locking mechanism 300 is located at the axial center position of the benchmark, so that the locking mechanism 300 floats the containing member 220. 20, the benchmark is in a vertical state, and the hollow member 310 is not in rigid contact with the containing member 220. When the support frame 100 and the horizontal support mechanism 200 are operated, the support frame 100 and the horizontal support mechanism 200 generate vibrations that are difficult to affect the floating locking mechanism 300 and the benchmark. Subsequently, by lowering the liquid level in the containing member 220, the locking mechanism 300 and the benchmark are driven to move downward until the bottom end of the benchmark contacts the ground, and then the support legs of the benchmark are connected to the benchmark, and the benchmark is supported by the support legs, and then the locking mechanism 300 is released from the clamping fixation of the benchmark, thereby separating the device from the benchmark and realizing the vertical placement of the benchmark.

[0031] Embodiment 1

[0032] like Figures 3 to 5As shown, in this embodiment, the two receiving members 220 are both C-shaped, the notches of the two receiving members 220 are in opposite directions, the outer contour of the hollow member 310 is smaller than the inner contour of the receiving member 220, one side of one of the two receiving members 220 is fixedly connected with a movable frame 210, and one side of the other receiving member 220 is fixedly connected with a fixed frame 270, the movable frame 210 is installed on the second vertical frame group 130, and the fixed frame 270 is fixedly installed between the top ends of the two vertical frame groups 120, and one side of the movable frame 210 and the fixed frame 270 is provided with a container tank 230 that can be movably adjusted up and down, and a lifting assembly 240 is provided on the outer side of the container tank 230, and the lifting assembly 240 is used to drive the container tank 230 to move up and down, and the two container tanks 230 are connected to the two There is a one-to-one correspondence between the individual containing parts 220, and a connecting pipe 260 is fixedly connected between the bottom end of the container tank 230 and the bottom end of the containing part 220. An inclined rail portion 131 is provided in the middle position of the second frame group 130, and the movable frame 210 is slidably sleeved between the two inclined rail portions 131. Both ends of the movable frame 210 are screwed together with a fixing knob 211, and a lower limit block 133 is fixedly sleeved at the bottom end of the inclined rail portion 131, and an upper limit block 134 is fixedly sleeved at the top end of the inclined rail portion 131. The fixing knob 211 is used to fix the fixing knob 211 to the inclined rail portion 131. A vertical rod portion 132 is provided at the top of the second frame group 130, and a lower pressure plate 140 is slidably sleeved between the two vertical rod portions 132, and a tightening knob is installed at one end of the lower pressure plate 140.

[0033] In this embodiment, the C-shaped setting of the receiving member 220 facilitates the locking mechanism 300 to enter the middle of the receiving member 220 from the notch position, and the opposite side settings of the notches of the two receiving members 220 make the combined center of gravity of the two hollow members 310 located at the central axis position of the hollow member 310, thereby facilitating the removal and insertion of the locking mechanism 300 from between the two receiving members 220, while keeping the center of gravity of the locking mechanism 300 on the central axis, so that the locking mechanism 300 remains vertical after floating, and clean water is added to the container tank 230, and the connecting pipe 260 is set to make the container tank 230 and the liquid levels in the receiving member 220 be in the same plane, and the height of the container tank 230 is adjusted by the lifting assembly 240 to adjust the liquid level in the receiving member 220, thereby facilitating the overall descent of the locking mechanism 300 by controlling the liquid level in the receiving member 220 to drop.

[0034] like Figures 3 to 6As shown, in this embodiment, the lifting assembly 240 includes a movable frame 241, the movable frame 210 and the fixed frame 270 are respectively fixedly connected to the adjacent movable frame 241, the lifting assembly 240 is slidably sleeved with the outer wall of the adjacent container tank 230, the outer wall of the movable frame 241 is fixedly connected with an internal threaded tube 242, the inner wall of the internal threaded tube 242 is screwed and connected with an external threaded sleeve 245, the bottom end of the external threaded sleeve 245 is rotatably connected with a bracket 244, and both sides of the bottom surface of the movable frame 241 are fixedly connected with sliding rods 2 43, the bracket 244 is slidably plugged between the two slide bars 243, a penetrating ridge hole is opened between the two ends of the external threaded sleeve 245, the horizontal support mechanism 200 is equipped with a ridge bar, a connecting pipe 250 is fixedly connected between the bottom ends of the two container tanks 230, a manual valve 251 is installed in the middle position of the connecting pipe 250, a connecting rod 320 is fixedly connected between the two sides of the inner wall of the two hollow parts 310, and a clamping module 330 is fixedly connected between the top and bottom ends of the two connecting rods 320.

[0035] During the specific implementation, the movable frame 210 is slid to the bottom end position of the inclined rail portion 131, and the movable frame 210 is limited by the lower limit block 133. At this time, the containing member 220 on one side of the movable frame 210 falls to the same height as the other containing member 220 (the height is the height relative to the base 110, not the absolute height relative to the ground), and then the manual valve 251 is opened to connect the two container tanks 230. Then, after adding liquid into one container tank 230, the two containing members 220 and the liquid levels in the two container tanks 230 are at the same height, and then the manual valve 251 is closed to disconnect the two container tanks 230, and the movable frame 210 is slid upward along the inclined rail portion 131 until the movable frame 210 contacts the upper limit block 134, and the movable frame 210 is fixed to the inclined rail portion 131 by the fixing knob 211. At this time, one containing member 220 moves to the other containing member 220. The locking mechanism 300 holding the standard rod is then inserted into the two receiving parts 220, and the hollow part 310 is floated on the corresponding receiving part 220. When the standard rod needs to be driven downward, the rib rod is simultaneously inserted into the two externally threaded sleeves 245, and the rib rod is rotated, thereby rotating the externally threaded sleeve 245 at the same time. The rotation of the externally threaded sleeve 245 drives the bracket 244 to move downward, and the downward movement of the bracket 244 drives the container tank 230 to move downward, so that the receiving part 2 The liquid in 20 flows back into the container tank 230, causing the liquid level in the containing member 220 to drop, thereby driving the locking mechanism 300 and the benchmark to move vertically downward until the bottom end of the benchmark contacts the ground, and loosening the fastening knob on the lower pressure plate 140 so that the lower pressure plate 140 slides downward along the vertical rod portion 132, so that the lower pressure plate 140 presses down on the top of the benchmark, thereby stabilizing the benchmark, making it convenient for the benchmark to remain stationary when the support legs are subsequently connected to the benchmark.

[0036] Embodiment 2

[0037] like Figure 6 As shown, in the present embodiment, the clamping module 330 comprises two clamping plates 331, the top ends of the two clamping plates 331 are rotatably connected to one side wall of the two connecting rods 320 respectively, one side of the bottom end of the clamping plate 331 is rotatably connected to a driving rod 332, a rotating seat 333 is rotatably connected between one ends of the two driving rods 332, the top end of the rotating seat 333 is rotatably connected to a threaded seat rod 334, a sliding groove is provided on one side of the threaded seat rod 334, a fixing ear 336 is slidably sleeved on the top end of the threaded seat rod 334, one end of the fixing ear 336 is fixedly connected to the inner wall of the adjacent hollow member 310, and the other end top surface of the fixing ear 336 is rotatably connected to a rotating member 335, the rotating member 335 is screwed and sleeved with the threaded seat rod 334, and the spacing between the two connecting rods 320 is smaller than the width of the C-shaped notch position of the containing member 220.

[0038] In specific implementation, the C-shaped setting of the hollow member 310 facilitates the insertion of the benchmark into the two connecting rods 320, and the hollow member 310 is separated from the benchmark. The rotating member 335 drives the threaded seat rod 334 to move upward, and the threaded seat rod 334 pulls the rotating seat 333 to move upward. The rotating seat 333 drives the bottom end of the clamping plate 331 to deflect upward through the driving rod 332, so that the bottom ends of the two clamping plates 331 clamp and fix the benchmark toward the middle. By setting the two clamping modules 330, the benchmark can be clamped in parallel. The support frame 100 and the horizontal support mechanism 200 are then separated from the benchmark pole, and the support frame 100 and the horizontal support mechanism 200 are separated from the benchmark pole, thereby realizing vertical calibration and placement of the benchmark pole.
