Description

Technical Field

[0001] The utility model relates to the field of positioning benchmarks, and more specifically, to a boundary positioning benchmark within the planned land range that prevents tipping. Background Art

[0002] Urban and rural planning is a general term for urban system planning, urban planning, town planning, rural planning, and village planning; it is a comprehensive deployment, specific arrangement, and implementation management of urban and rural social and economic development, land use, spatial layout, and various construction projects within a certain period. During the process of urban and rural planning and construction, land surveys are required, and positioning markers are needed during the surveys, and positioning benchmarks are used.

[0003] After retrieval, the existing patent (publication number: CN218628350U) discloses a positioning benchmark, which includes a first rod body, a second rod body, and a straightness detection mechanism. The first rod body and the second rod body are coaxially arranged, and one end of the first rod body and one end of the second rod body are detachably connected; the end of the first rod body away from the second rod body is a tapered end, and the end of the second rod body away from the first rod body is detachably connected to the straightness detection mechanism. The straightness detection mechanism is used to assist the vertical insertion of the first rod body and the second rod body into the ground after combination. In the technical solution proposed by the utility model, the first rod body and the second rod body are combined before insertion, and during insertion, the straightness detection mechanism assists the staff to use, so that the staff can insert the positioning benchmark straight into the land to be surveyed, ensuring the accuracy of the measurement data. The inventor found the following problems in the prior art during the implementation of the present utility model:

[0004] The bottom end of the existing positioning benchmark is often spiked for easy fixation. When carrying, the spiked part is often not easy to store and can easily stab the staff or pierce the carrying items. At the same time, when the rod body of the positioning benchmark is tilted during positioning, it often does not have the function of assisting verticality, and it is easy for the rod body to tip over.

[0005] Therefore, a boundary positioning benchmark within the planned land range that prevents tipping is proposed to solve the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a boundary positioning benchmark within the planned land range that prevents tipping to solve the problems raised in the above background art.

[0007] To achieve the above object, the present utility model provides the following technical solution: A boundary positioning benchmark within the planned land range that prevents tipping, including a main rod. An adjusting rod is embedded in the inner wall of the top of the main rod. Scale lines are provided on the surface of the adjusting rod. A limiting groove is provided at one end of the main rod away from the adjusting rod. A positioning cone is embedded in the limiting groove. A screw rod is connected to the top of the positioning cone. The outer wall of one end of the screw rod away from the positioning cone is threadedly connected to a threaded cylinder. One end of the threaded cylinder away from the screw rod is connected to the inner wall of the limiting groove through a bearing. A worm gear is connected to the outer wall of the threaded cylinder. One side of the bottom of the main rod is connected to an adjusting shell. The adjusting shell is communicated with the limiting groove. A worm is connected to the inner wall of the middle of the adjusting shell through a bearing. The worm meshes with the worm gear. An adjusting knob is provided on one side of the adjusting shell. The adjusting output end of the adjusting knob is connected to the worm. Limiting chutes are provided at both ends of the limiting groove. Sliders are connected to both outer walls of the positioning cone. The sliders are embedded in the limiting chutes.

[0008] Preferably, a fixing ring is connected to the outer wall of the middle of the main rod through bolts. Electric push rods are arranged in an array connection at the edge of the fixing ring through damping rotating shafts.

[0009] Preferably, one end of the electric push rod away from the fixing ring is connected to a counterweight through a rotating shaft. An anti-slip pad is connected to the bottom end of the counterweight through bolts.

[0010] Preferably, a level is provided above the outer wall of one side of the main rod. A controller is connected to the bottom end of the level. The controller is connected to the level and the electric push rod through electric wires respectively.

[0011] Preferably, an rtk positioning instrument is screwed to the top of the adjusting rod. A strip-shaped groove is provided on the outer wall of one side of the adjusting rod.

[0012] Preferably, a fixing mechanism is provided on one side of the top of the main rod. The fixing mechanism includes a movable groove, an adjusting bolt, an abutting block and an adjusting rotating ring. The inner wall of the movable groove is threadedly connected to the adjusting bolt. One end of the adjusting bolt is connected to the abutting block. The abutting block is embedded in the strip-shaped groove. One end of the adjusting bolt away from the abutting block passes through the main rod and is connected to the adjusting rotating ring.

[0013] The technical effects and advantages of the present utility model:

[0014] 1. Compared with the prior art, when carrying the boundary positioning benchmark within the planned land area that prevents tipping, the adjustment knob can be twisted. The rotation of the adjustment knob drives the worm to rotate, and the rotation of the worm drives the worm wheel to rotate, thereby causing the threaded cylinder to rotate. The rotation of the threaded rod drives the screw rod to contract and translate, thereby driving the positioning cone to retract into the limiting groove. At the same time, when the positioning groove moves, it drives the slider to slide in the limiting chute so that the positioning cone can move smoothly. By retracting the positioning cone, it is avoided that the pointed part of the positioning cone pierces the carried objects or accidentally injures the staff during the process of carrying the positioning benchmark.

[0015] 2. Compared with the prior art, the boundary positioning benchmark within the planned land area that prevents tipping can detect the horizontal angle of the main rod through a level. When the inclination of the main rod exceeds the set safety range, a signal is transmitted to the controller, and the controller controls the electric push rod to push the main rod, thereby preventing the positioning benchmark from tipping over.

A limiting groove 4 is arranged at one end of the main rod 1 away from the adjusting rod 2. A positioning cone 5 is embedded in the limiting groove 4. A screw rod 6 is connected to the top of the positioning cone 5. The outer wall of one end of the screw rod 6 away from the positioning cone 5 is threadedly connected to a threaded cylinder 7. One end of the threaded cylinder 7 away from the screw rod 6 is connected to the inner wall of the limiting groove 4 through a bearing. A worm gear 8 is connected to the outer wall of the threaded cylinder 7. One side of the bottom of the main rod 1 is connected to an adjusting shell 9. The adjusting shell 9 is communicated with the limiting groove 4. A worm 10 is connected to the inner wall of the middle of the adjusting shell 9 through a bearing. The worm 10 meshes with the worm gear 8. An adjusting knob 11 is arranged on one side of the adjusting shell 9. The adjusting output end of the adjusting knob 11 is connected to the worm 10. Limiting chutes 12 are arranged at both ends of the limiting groove 4. Sliders 13 are connected to the outer walls on both sides of the positioning cone 5. The sliders 13 are embedded in the limiting chutes 12.

[0023] Among them: The adjusting rod 2 can be telescoped above the main rod 1 to facilitate adjusting the height of the RTK positioning instrument 21 during positioning for accurate positioning.

The rotation of the adjusting knob 11 drives the worm 10 to rotate. The rotation of the worm 10 drives the worm gear 8 to rotate, so that the threaded cylinder 7 rotates. The rotation of the threaded rod 7 drives the screw rod 6 to perform a contraction and translation movement, thereby driving the positioning cone 5 to retract into the limiting groove 4. At the same time, when the positioning cone 5 moves, it drives the slider 13 to slide in the limiting chute 12 so that the positioning cone 5 can move smoothly. By retracting the positioning cone 5, it is avoided that the pointed part of the positioning cone 5 pierces the carried objects or accidentally injures the staff during the process of carrying the positioning benchmark. Embodiment

[0024] Based on Embodiment 1, the solution in Embodiment 1 is further refined and introduced in combination with the following specific working methods, as Figures 1 to 4 shown, and the details are described in the following text:

[0025] As a preferred embodiment, a fixing ring 14 is connected to the outer wall of the middle part of the main rod 1 by bolts, and electric push rods 16 are arranged and connected at the edge of the fixing ring 14 through damping rotating shafts 15; further, the main shaft 1 can be assisted in positioning and fixing by expanding multiple groups of electric push rods 16, thereby preventing the positioning benchmark from tipping over. As a preferred embodiment, one end of the electric push rod 16 away from the fixing ring 14 is connected to a counterweight 17 through a rotating shaft, and an anti-slip pad 18 is connected to the bottom end of the counterweight 17 by bolts; further, the counterweight 17 increases the weight of the bottom end of the electric push rod 16, making it more stable, and at the same time, the anti-slip pad 18 plays an anti-slip role.

[0026] As a preferred embodiment, a spirit level 19 is arranged above the outer wall of one side of the main rod 1, the bottom end of the spirit level 19 is connected to a controller 20, and the controller 20 is connected to the spirit level 19 and the electric push rod 16 through wires; further, the horizontal angle of the main rod can be detected by the spirit level 19. When the inclination of the main rod 1 exceeds the set safety range, a signal is transmitted to the controller 20, and the controller 20 controls the electric push rod 16 to push the main rod 1, thereby preventing the positioning benchmark from tipping over.

[0027] As a preferred embodiment, an RTK positioning instrument 21 is screwed to the top of the adjusting rod 2, and a strip-shaped groove 22 is arranged on the outer wall of one side of the adjusting rod 2; further, the RTK positioning instrument 21 is a high-precision global positioning system (GPS) technology, which can provide centimeter-level real-time positioning information and quickly and accurately obtain the spatial position information of ground features, which is crucial for topographic surveying in national land space planning, so as to locate the boundaries within the planned land area, and the strip-shaped groove 22 plays a limiting role.

[0028] As a preferred embodiment, a fixing mechanism 23 is arranged on one side of the top of the main rod 1. The fixing mechanism 23 includes a movable groove 24, an adjusting bolt 25, an abutting block 26 and an adjusting rotating ring 27. The inner wall of the movable groove 24 is threadedly connected with the adjusting bolt 25, one end of the adjusting bolt 25 is connected to the abutting block 26, the abutting block 26 is embedded in the strip-shaped groove 22, and the end of the adjusting bolt 25 away from the abutting block 26 passes through the main rod 1 and is connected to the adjusting rotating ring 27; further, by twisting the adjusting rotating ring 27, the adjusting bolt 25 can be driven to rotate, thereby pushing the abutting block 26 to abut against the inner wall of the strip-shaped groove 22, so as to position and fix the adjusting rod 2.

[0029] The working process of the utility model is as follows: First, the adjusting rod 2 can be telescoped above the main rod 1 to facilitate adjusting the height of the RTK locator 21 during positioning for accurate positioning.
