Description

Technical Field

[0001] The utility model belongs to the technical field of surveying and mapping, and in particular relates to a surveying and mapping beacon fixing device. Background Art

[0002] During the planning, design, construction and operation and management stages of engineering construction, it is often necessary to mark certain geographical locations. Currently, beacon poles are usually inserted into the ground as an indication to facilitate subsequent surveying and mapping work by observers. In order to reduce measurement errors, it is necessary to ensure that the beacon is perpendicular to the ground.

[0003] A Chinese patent with publication number CN215491740U discloses a beacon indicating device for airport survey and mapping. The solution includes a connecting block with a spherical cavity, support legs and a sphere. The support legs are arranged at intervals on the outer side of the connecting block, and the sphere is embedded in the cavity. A benchmark is fixed above the sphere, and a plumb bob is fixed below the sphere. The above solution uses the gravity of the plumb bob to rotate the sphere relative to the cavity, ensuring that the benchmark is in a vertical state, thereby improving the accuracy of surveying and mapping.

[0004] When the above solution is in use, it is necessary to unfold the three support legs arranged at intervals on the outer surface of the connecting block to support the connecting block, resulting in the orthographic projection of the benchmark at the upper end of the sphere always being located between the three support legs, which in turn makes it impossible for the benchmark to mark the geographical location of the adjacent edge, and the applicable scenarios are relatively limited. Utility Model Content

[0005] The utility model aims to provide a surveying and mapping beacon fixing device to solve the problem that the application scenarios of the above-mentioned solution are relatively limited.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A surveying and mapping beacon fixing device comprises a centering rod and a sphere, wherein one side of the top of the centering rod is rotatably connected to two supporting rods, the sphere is fixedly provided with a benchmark pole along the center of the sphere, a plumb bob is fixedly provided at the bottom of the benchmark pole, and a platform for installing the beacon is fixedly provided at the top of the benchmark pole, the sphere is arranged above the centering rod and can rotate relative to the centering rod.

[0008] The principle and effect of this technical solution:

[0009] Place the bottom of the centering rod on the edge of the geographical location to be marked, unfold the two supporting rods, and make the bottoms of the supporting rods contact the ground to fix the device. The sphere rotates relative to the centering rod under the action of the gravity of the plumb bob until it is in a stationary state. At this time, the pole is vertical relative to the horizontal plane.

[0010] Through the above setting, the sphere is set above the centering rod, and the centering rod is placed at the geographical location to be marked on the edge, so that the geographical location on the edge can be marked, ensuring the accuracy of the surveying and mapping results while solving the problem of the limited applicable scenarios of the above solution.

[0011] The utility model also includes an extension mechanism, which includes a first cross bar and a second cross bar. A first rotating shaft is fixedly provided at the bottom of one end of the first cross bar, a groove is provided at the top of the centering rod, the first rotating shaft is rotatably inserted in the groove, and is connected to the centering rod through a locking assembly, a connecting rod is fixedly provided at the top of the other end of the first cross bar, a second rotating shaft is fixedly provided at the bottom of one end of the second cross bar, the second rotating shaft is rotatably inserted in the connecting rod, and a cavity cooperating with the sphere is provided at the other end of the second cross bar, openings are provided at the top and bottom of the cavity, the sphere is rotatably embedded in the cavity, and the two ends of the benchmark rod pass through the corresponding openings respectively.

[0012] In the utility model, a driving rod is rotatably inserted in the first crossbar along its length direction, a second bevel gear is fixedly sleeved outside the second rotating shaft, and a first bevel gear meshing with the second bevel gear is fixedly sleeved at one end of the driving rod close to the second rotating shaft.

[0013] In the utility model, the locking assembly includes a limit block and a compression spring. A limit shaft is fixedly arranged at the bottom of the first rotating shaft. The outer periphery of the limit shaft has edges arranged at equal intervals. The limit block is slidably embedded in the groove, and a groove is recessed at the top of the limit block to cooperate with the edges of the limit shaft. The compression spring is arranged between the limit block and the bottom wall of the groove.

[0014] In the utility model, a through slot is formed on the side wall of the groove, and a protrusion which is slidably arranged in the through slot is fixedly provided on the side wall of the limiting block.

[0015] The principle and effect of this technical solution:

[0016] Press the protrusion downward to lower the limit block, so that the limit block is separated from the limit shaft, and then the first cross bar is rotated to an appropriate position, and the protrusion is released. The limit block moves upward under the action of the compression spring and makes the limit shaft clamped in the slot, thereby preventing the first cross bar from continuing to rotate. Then, the driving rod is rotated, and the driving rod drives the second rotating shaft to rotate through the first bevel gear and the second bevel gear to rotate the second cross bar to an appropriate position. The plumb bob naturally falls under the action of gravity, thereby ensuring that the benchmark is perpendicular to the horizontal plane.

[0017] Through the above arrangement, the device can be set up at a location far away from the edge, and the geographical location of the edge can be marked, thereby reducing the risk of falling of surveying personnel and surveying equipment and improving the safety when marking the geographical location of the edge.

[0018] In the utility model, a screw rod is threadedly inserted into the bottom of the centering rod, and a spike portion is arranged at the bottom of the screw rod.

[0019] In the utility model, a rod sleeve is slidably sleeved outside the support rod, and a bolt is threadedly penetrated through the side wall of the rod sleeve, and one end of the bolt can be pressed against the support rod.

[0020] In the utility model, the bottom of the rod sleeve is rotatably connected with a support plate, and the top of the support plate is slidably penetrated with a drill rod.

[0021] The principle and effect of this technical solution:

[0022] According to the actual situation, the screw rod is rotated to change the placement height of the ball relative to the ground, and the rod sleeve is slid to make the first cross bar tend to be horizontal. At this time, the support plate contacts the ground, and a drill rod is inserted into the top of the support plate and inserted into the ground.

[0023] Through the above-mentioned arrangement, on the one hand, the height of the sphere relative to the ground can be changed to make it suitable for more application scenarios; on the other hand, the device can be fixed to the ground to prevent the device from tipping over during the rotation of the first cross bar and the second cross bar, thereby improving the stability of the utility model during use.

[0024] In the present invention, the diameter of the opening is smaller than the diameter of the sphere.

[0025] In the utility model, an infrared emitter is fixedly embedded in the bottom of the plumb bob along its axial direction. Through the above arrangement, it is convenient for surveying and mapping personnel to align the geographical location to be marked, thereby ensuring the accuracy of the surveying and mapping results.

A connecting rod 412 is fixedly provided at the top of the other end of the first cross bar 41, and a second rotating shaft 421 is fixedly provided at the bottom of one end of the second cross bar 42. The second rotating shaft 421 is rotatably inserted into the connecting rod 412, and a cavity 422 matching the sphere 30 is provided at the other end of the second cross bar 42. Openings 423 are provided at the top and bottom of the cavity 422. The sphere 30 is rotatably embedded in the cavity 422, and the two ends of the marker 31 pass through the corresponding openings 423 respectively.

[0036] In this embodiment, a driving rod 413 is rotatably inserted in the first crossbar 41 along its length direction, a second bevel gear 62 is fixedly sleeved outside the second rotating shaft 421, and a first bevel gear 61 meshing with the second bevel gear 62 is fixedly sleeved on one end of the driving rod 413 close to the second rotating shaft 421.

[0037] In this embodiment, the locking assembly 50 includes a limit block 51 and a compression spring 52. A limit shaft 414 is fixedly arranged at the bottom of the first rotating shaft 411. The outer periphery of the limit shaft 414 has edges arranged at equal intervals. The limit block 51 is slidably embedded in the groove 11, and the top of the limit block 51 is recessed with a slot 511 that cooperates with the edge of the limit shaft 414. The compression spring 52 is arranged between the limit block 51 and the bottom wall of the groove 11.

[0038] In this embodiment, a through slot 111 is formed on the side wall of the groove 11 , and a protrusion 512 that is slidably disposed in the through slot 111 is fixedly disposed on the side wall of the limiting block 51 .

[0039] In this embodiment, a screw rod 12 is threadedly inserted into the bottom of the centering rod 10 , and a spike portion is provided at the bottom of the screw rod 12 .

[0040] In this embodiment, a rod sleeve 21 is slidably sleeved outside the support rod 20 , and a bolt 211 is threadedly penetrated through the side wall of the rod sleeve 21 , and one end of the bolt 211 can be pressed against the support rod 20 .

[0041] In this embodiment, the bottom of the rod sleeve 21 is rotatably connected to a support plate 22 , and a drill rod 221 is slidably penetrated through the top of the support plate 22 .

The sphere 30 rotates relative to the centering rod 10 under the action of the gravity of the plumb bob 32 until it is in a stationary state. At this time, the marker rod 31 is vertical relative to the horizontal plane.

[0046] The protrusion 512 is pressed downward to lower the limit block 51, so that the limit block 51 is disengaged from the limit shaft 414, and then the first cross bar 41 is rotated to an appropriate position, and the protrusion 512 is released. The limit block 51 moves upward under the action of the compression spring 52, and the limit shaft 414 is clamped in the clamping groove 511, thereby preventing the first cross bar 41 from continuing to rotate.
