Description

Technical Field

[0001] The utility model relates to the field of engineering surveying and mapping, in particular to a benchmark for engineering surveying and mapping. Background Art

[0002] During the exploration and surveying of mineral resources such as coal and oil, a benchmark is needed to indicate the measuring point, so that surveyors can perform accurate measurement and positioning. The traditional engineering surveying benchmark is usually a rod with a conical plug at the bottom. The outer surface of the rod is painted with red and white paint with scales. When in use, the conical plug is manually inserted into the measuring point. This type of rod has no additional support structure and is not very stable. It is easy to tilt or even fall due to external forces during use, and needs to be readjusted, which affects the progress of surveying and mapping, resulting in certain limitations in its use.

[0003] In order to reduce the deflection of the surveying and mapping pole due to external forces such as wind during use, the existing technology (publication number: CN220153588 U) installs a support part at the lower end of the surveying and mapping pole, and presses the surveying and mapping pole with a positioning piece set on the mounting support part; at the same time, the existing technology is also provided with a shaking detection part and an alarm device to ensure the accuracy of the pole calibration height, and when the mounting support part shakes, the device will alarm. The disadvantage of this existing technology is that when encountering a strong external force, the entire device will shake, and at this time, the only way to rely on the alarm to remind the surveyor to manually control it.

[0004] Based on this, it is necessary to provide a benchmark with higher stability for engineering surveying. Utility Model Content

[0005] In view of the technical problem that the existing surveying and mapping benchmarks are insufficiently stable, the utility model provides a benchmark for engineering surveying and mapping. When in use, the limit rod of the limit assembly is extended and inserted into the soil, which improves the standing stability of the device, can effectively reduce the occurrence of tilting or tipping of the surveying and mapping pole, and enhances the ability of the device to resist external forces.

[0006] The technical solution of this utility model is as follows:

[0007] A benchmark for engineering surveying and mapping comprises a surveying and mapping rod, the bottom of which is connected to a limit cylinder via a fixed seat, a driving motor is arranged inside the limit cylinder, an output end of the driving motor is connected to a rotating shaft, at least one set of limit components is arranged on the rotating shaft, the limit components comprise a gear and a toothed plate, the gear is sleeved on the rotating shaft, an outer wall of the gear is meshedly connected to the toothed plate, one end of the toothed plate is connected to a telescopic rod, the other end of the toothed plate is connected to a limit rod, and the limit cylinder is provided with an opening for the limit rod to pass through.

[0008] Furthermore, two sets of limit assemblies are arranged on the rotating shaft, and the tooth plates of the two sets of limit assemblies are perpendicular to each other.

[0009] Furthermore, each set of limiting components includes two tooth plates, the two tooth plates are arranged relative to the gears, and the telescopic rods and the limiting rods on the two tooth plates are arranged in opposite directions.

[0010] Furthermore, an electric push rod is provided on both sides of the gear of each set of limiting components. The electric push rod is located between the two tooth plates. The extended end of the electric push rod faces the gear and is fixed with an arc plate. The other end of the electric push rod is fixed on the limiting cylinder.

[0011] Furthermore, a power supply and a controller are provided inside the fixing seat, the power supply is electrically connected to the controller, an operation button is provided on the outer surface of the fixing seat and is electrically connected to the controller, and the controller is also controlled and connected to the drive motor and / or the electric push rod respectively.

[0012] Furthermore, the surveying rod is threadedly connected to the fixing seat.

[0013] Furthermore, connecting seats are arranged at equal intervals on the outer wall of the fixing seat, the number of the connecting seats is at least three, and the inside of the connecting seat is connected to the supporting legs through a rotating rod.

[0014] Furthermore, the end of the free end of the limiting rod, the bottom of the limiting cylinder, and the bottom of the supporting leg are respectively provided with conical heads.

[0015] The beneficial effects of the utility model are:

[0016] The engineering surveying benchmark provided by the utility model, when in use, the surveying rod is inserted into the soil, and the driving motor inside the limit cylinder drives the rotating shaft and the gear to rotate, thereby driving the toothed plate to move, so that the limit rod extends from the limit cylinder into the soil, thereby improving the standing stability of the benchmark, and further reducing the risk of the benchmark being tilted or even toppled when subjected to external force, thereby improving the practicability of the device to a certain extent, and making the device more widely applicable.
